In order to enable the roller 6 to effectively roll on the inner wall of the crack; as shown in fig. 5, an elastic rubber layer is arranged on the outer wall of the roller 6; through setting up the elastic rubber layer, can improve the frictional force of gyro wheel 6 and crack inner wall to let gyro wheel 6 also can carry out effectual rotation when the device of caulking moves forward.

When the asphalt filling device is used, firstly, melted asphalt is filled into the storage box 2, then the joint filling device is pushed by the handle 12 to move to a crack to be filled, then the electric push rod 3 is controlled to push the push frame 17 to move downwards, the push frame 17 can push the U-shaped plate 5 to move downwards integrally, so that the high-pressure spray pipe 7 positioned at the bottom of the U-shaped plate 5 is inserted into the crack, at the moment, a worker can open the high-pressure spray pipe 7, the asphalt stored in the storage box 2 can enter the high-pressure spray pipe 7 through the conveying pipe 16 and the conveying hose 19, then the asphalt is sprayed into the crack through the high-pressure spray pipe 7 to fill the crack, the worker can push the joint filling device to continuously advance to repair the crack, when the crack with concave and convex inner wall needs to be filled, after the high-pressure spray pipe 7 is inserted into the crack, the four rollers 6 positioned at the bottoms of the first sliding block 20 and the second sliding block 25 can be respectively supported on the inner walls at two sides of the crack, along with the continuous forward movement of the caulking device, when the roller 6 moves to the position with uneven inside of the crack, the mounting plate 18 rotates through the rotating column 27 and the return turntable 26, and simultaneously the mounting plate 18 is pushed by the thrust to push the first sliding block 20 and the second sliding block 25 to move relatively, at this time, the elastic telescopic rod 23 can guide and limit the first sliding block 20 and the second sliding block 25 in relative movement, and simultaneously buffer the thrust received by the first sliding block 20 and the second sliding block 25, so that the high-pressure nozzle 7 can adjust the position along with the first sliding block 20 inside the crack, a worker only needs to push the caulking device to move forward along the crack at a constant speed, the T-shaped sliding groove 21 and the T-shaped sliding block 34 can effectively guide and fix the first sliding block 20 and the second sliding block 25, and the stability of the first sliding block 20 and the second sliding block 25 during the back-and forth movement is improved, meanwhile, the insertion port 31 can guide and limit the fixing plate 30, so that the overall stability of the high-pressure spray pipe 7 during working is improved.

When the two mounting plates 18 and the high-pressure nozzle 7 between the two mounting plates 18 need to be inserted into the crack, a worker firstly pushes the first sliding block 20 and the second sliding block 25 relatively to enable the inserting fixing block 33 to be inserted into the inserting frame 28, then fixes the inserting fixing block 33 in the inner wall of the inserting frame 28 through screws, so that the two mounting plates 18 can be tightly attached to the two sides of the high-pressure nozzle 7, the unfolding area of the two mounting plates 18 is greatly reduced, the two mounting plates 18 can be conveniently inserted into the crack to be repaired, after the two mounting plates 18 are inserted into the crack, the worker can twist off the screws for fixing the inserting fixing block 33, at the moment, the first sliding block 20 and the second sliding block 25 can be flicked towards the two sides under the action of the elastic telescopic rod 23, and the four rollers 6 at the two sides of the mounting plates 18 are abutted to the inner walls at the two sides of the crack, and then the crack filling operation can be started, when the rotating column 27 is stressed to rotate through the return turntable 26, the arc-shaped guide groove 35 and the rotating guide plate 24 can guide the rotation of the mounting plate 18 and the rotating column 27, the guide block 29 and the guide sliding groove 32 can guide the back-and-forth movement of the fixing plate 30, the conveying hose 19 passes through the conveying interface 36 to be connected with the fixing plate 30, when the fixing plate 30 moves back and forth along with the first sliding block 20 and the second sliding block 25, the conveying hose 19 also moves back and forth along with the fixing plate 30, at the moment, the connecting block 37 can slide back and forth along with the conveying hose 19 on the inner wall of the rectangular through groove 22, and therefore the whole conveying hose 19 is guided and limited.

The deflector 4 can lead to U template 5, let U template 5 can be more stable when reciprocating through electric putter 3, staff's accessible slide bar 13 adjusts the height of scraping the flat board 15 apart from ground, when the device of caulking begins the during operation, the staff will scrape flat board 15 and adjust to the height of hugging closely ground, scrape flat board 15 and remove along with the device this moment, and scrape flat to overflowing fissured pitch, balancing weight 14 can improve the whole weight of scraping flat board 15, let scraping flat board 15 can be better flatten overflowing fissured pitch, limiting plate 11 can carry on spacingly to slide bar 13's position simultaneously, also let two slide bars 13 connect to become a whole simultaneously, let slide bar 13 can be better support and fix scraping flat board 15.

Example 2:

a using method of an asphalt high-pressure gap filling device for water conservancy construction is shown in figures 1-7 and comprises the following steps:

s1: firstly, injecting melted asphalt into the storage box 2, and then pushing the gap filling device to move to a crack needing to be filled through the handle 12;

s2: the worker pushes the first sliding block 20 and the second sliding block 25 relatively to insert the insertion fixing block 33 into the insertion frame 28, and then fixes the insertion fixing block 33 in the inner wall of the insertion frame 28 through screws;

s3: the operator controls the electric push rod 3 to push the push frame 17 to move downwards, so that the high-pressure spray pipe 7 and the mounting plates 18 on the two sides are inserted into the crack, and then screws for fixing the inserting and connecting fixing blocks 33 are screwed off;

s4: the operator moves the scraping plate 15 to the position close to the ground through the sliding rod 13, then opens the high-pressure spray pipe 7, and pushes the caulking device to move forward along the crack at a constant speed through the handle 12;

s5: after the crack filling device is pushed to the end of the crack, the high-pressure spray pipe 7 is controlled to be closed, the electric push rod 3 is controlled to reset, then the handle 12 is used for pushing the crack filling device to return to the original way, the scraping plate 15 is used for flattening the asphalt overflowing the crack again, and therefore the crack repairing work is completed.
