The working principle is as follows: this electric power steel pipe quick connect structure, at the in-process that the steel pipe is connected, at first as shown in fig. 1, insert the upper end of a steel pipe in the cover seat 2 of another steel pipe lower extreme, later can accomplish the connection to the steel pipe through rotating main drive post 83, whole process is not only simple but also quick very big improvement the efficiency that the tower was connected to the steel pipe group, corresponding efficiency that whole tower was built has also been improved, the concrete joint process is as follows:

in the process of rotation of the main driving column 83, the annular connecting member 82 is driven to rotate, in the process of rotation of the annular connecting member 82, the rotating portion 71 is synchronously driven to rotate in the fixed seat 81, in the process of rotation, the rotating portion 71 drives the corresponding incomplete thread sliding portion 72 to rotate, at this time, due to the threaded connection of the incomplete thread sliding portion 72 and the sleeve seat 2, the incomplete thread sliding portion 72 synchronously slides upwards in the process of rotation, the incomplete thread sliding portion 72 slides upwards to drive the bevel block 11 thereon to synchronously move upwards, as shown in fig. 4, at this time, under the limitation of the bevel groove 10, the supporting member 6 is forced to slide in the direction of the steel pipe inserted into the sleeve seat 2, in the process of sliding, the supporting member 6 synchronously drives the flexible tightening sleeve 5 connected thereto to move, at this time, as shown in fig. 2, because the flexible tightening sleeve 5 is uniformly sleeved on the flexible connecting portion 3 and the rigid connecting portion 4, when support piece 6 drives rather than 5 synchronous movement of the tough tightening sleeve of coupling part, the tough tightening sleeve 5 can be because of the synchronous steel pipe direction slip of pegging graft in all flexible connecting portion 3 of drive of deformation and rigid connection portion 4 to the cover seat 2, and be connected with the steel pipe, tighten up fixedly to the steel pipe, whole connection process is not only simple quick, and simultaneously, it is fixed with unified synchronous tightening up through the direct grafting of steel pipe, the precision of steel pipe connection has effectively been improved, corresponding reduction connection error's production, and then the relative stability and the anti stress ability that have improved the shaft tower.

In the process of connecting the steel pipes, as shown in fig. 3, the flexible connecting part 3 is composed of rubber blocks which are uniformly distributed, the contact surface of the rubber blocks and the steel pipes is in a concave arc shape, when the arc-shaped receiving and limiting block 31 is driven by the tightening force of the flexible tightening sleeve 5 to move towards the steel pipe and tighten and fix the steel pipe, the uniformly distributed rubber blocks are used for contacting and fixing the steel pipe, and when the rubber blocks are contacted and fixed with the steel pipe due to the higher friction coefficient of the rubber material, can effectively reduce the sliding deviation of the steel pipe, can utilize the clearance between the rubber blocks to accelerate the air flow in the steel pipe, avoid the influence of the inner heat dissipation caused by the over-closed steel pipe, of course, the flexible connecting portion 3 may be provided as an arc rubber layer or uniformly distributed rubber strips corresponding to the arc receiving limiting blocks 31 as required.

Secondly, through the cooperation of the rotating part 71 of the pushing part 7 and the incomplete thread sliding part 72, in the connection process, the supporting part 6 can be pushed to drive the tough tightening sleeve 5 to move synchronously, and the position of the supporting part 6 to move can be locked instantly through the threaded connection of the incomplete thread sliding part 72 and the sleeve seat 2, so that the situation that the supporting part 6 moves backwards in the moving process can be effectively prevented, and further the stability of the supporting part 6 in the moving process is improved, correspondingly, the toughness tightening sleeve 5 is improved to drive the flexible connecting part 3 and the rigid connecting part 4 to tighten and fix the corresponding steel pipe, and meanwhile, through the threaded connection of the incomplete thread sliding part 72 and the sleeve seat 2, the convenience of the steel pipe connection operation is also improved.

In addition, as shown in fig. 6, the flexible tightening sleeve 5 is a flexible annular closed sleeve formed by mutually fastening iron rings, so that the flexible tightening sleeve 5 not only has stable tightening force, but also has a longer service life, wherein the smaller the iron, the greater the softness, the greater the corresponding cost, and therefore the removable attachment of the flexible tightening sheath 5 to the support 6, for its repeated use, of course, the iron ring can be made of other rigid metals, and the flexible tightening sleeve 5 can be other annular closed sleeves with high toughness and flexible deformation force but no elasticity, such as an annular closure sleeve woven from iron or steel wire or an annular closure sleeve made from carbon fibre cloth, secondly, because the general diameter of the steel pipe for the pole tower is larger, the corresponding needed 5-circumference-length of the toughness tightening sleeve is also larger, and the influence of the rigidity of the single iron ring on the flexibility of the whole flexible annular closing sleeve can be basically not considered.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
