[0029] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0030] The first implementation method:

[0031] Figure 1-9 and Figure 10-13 A heavy-duty connector for an intelligent construction hoist is shown, comprising an electrical control cabinet 23 with a heavy-duty connector 1, the outer end of the heavy-duty connector 1 is fixedly connected to an insulating shell 2, a round hole is provided at the side end of the insulating shell 2, a waterproof joint 3 is fixedly connected inside the round hole, vertical pipes 4 are fixedly connected to the upper and lower ends of the waterproof joint 3, a horizontal pipe 5 is fixedly connected to the end of the vertical pipe 4 away from the waterproof joint 3, a moving block 6 is movably inserted inside the horizontal pipe 5, a tension spring 7 is fixedly connected between the side end of the moving block 6 and the inner wall of the horizontal pipe 5, a bent pipe 8 is fixedly connected to the end of the moving block 6 away from the tension spring 7, a moving pipe 9 is movably inserted inside the bent pipe 8, a limit block 10 is fixedly connected to the end of the moving pipe 9 away from the bent pipe 8, an arc groove is provided at the end of the limit block 10 away from the moving pipe 9, and the arc groove is used to facilitate the limit block 10 to clamp the cable, and a mounting plate 22 with a plurality of mounting holes is fixedly connected to the lower end of the heavy-duty connector 1;

[0032] The end of the movable tube 9 away from the limit block 10 is fixedly connected with an extrusion block 11, the outer end of the movable tube 9 is sleeved with a compression spring 12, the outer end of the bent tube 8 is provided with a pair of through holes 13, and an inclined plate 14 is movably inserted inside the through hole 13. The end of the extrusion block 11 away from the movable tube 9 is in contact with the outer end of the inclined plate 14, and the end of the inclined plate 14 close to the waterproof joint 3 is fixedly connected with a rectangular block 15, and the internal thread of the rectangular block 15 is connected with a threaded tube 16. The outer end of the bent tube 8 is provided with a plurality of reinforcement grooves 17 movably inserted with the threaded tube 16, the outer end of the movable block 6 is fixedly connected with a pair of sliders 18, and a pair of slide grooves 19 movably inserted with the sliders 18 are provided on the inner wall of the cross tube 5. In the initial state, the tension spring 7 is in an extended state, and the outer diameter of the extrusion block 11 is larger than the outer diameter of the compression spring 12.

[0033] This application is divided into the following steps:

[0034] Step 1: Install, use bolts to fix the mounting plate 22 on the electrical control cabinet 23, and then install the heavy-duty connector 1 on the electrical control cabinet 23 (combined with Figure 2 As shown), then install the electrical control cabinet 23 on the lift:

[0035] Step 2: Pass one end of the cable (indicated by M in the figure) through the waterproof connector 3, extend it into and install it inside the heavy-duty connector 1. When the cable passes through the waterproof connector 3, the remaining length is greater than the length of the waterproof connector 3 groove (combined with Figure 4As shown), to prevent the connection between the heavy-duty connector 1 and the heavy-duty connector 1 from loosening due to the tightening of the cable, and then push the inclined plate 14 so that the inclined plate 14 pushes the extrusion block 11 and the movable tube 9 to move toward one end close to the cable. During the movement of the inclined plate 14, the extrusion block 11 will squeeze the compression spring 12. At the same time, the movable tube 9 will push the limit block 10 to move toward the cable and clamp the cable to improve the stability of the cable after installation. Finally, install the threaded tube 16 in the rectangular block 15 so that one end of it is inserted into the corresponding reinforcement groove 17 to prevent the inclined plate 14 from moving;

[0036] Step 2: When the cable is pulled by external force and the end of the cable connected to the waterproof connector 3 moves toward the outside of the waterproof connector 3, the remaining portion of the cable in the waterproof connector 3 will be straightened (combined with Figure 5 As shown), at the same time, the cable will drive the extrusion block 11 and the moving block 6 to move together to the side away from the waterproof joint 3, so that the tension spring 7 continues to be stretched by the moving block 6, and one end of the moving block 6 moves out of the horizontal tube 5 (combined with Fig. 9 As shown), at the same time, the slider 18 will move in the slide groove 19, and under the action of the elastic force of the tension spring 7, it will exert a reaction force on the cable, pulling the cable to move toward the waterproof connector 3, thereby not only making it difficult for the cable to continue to move toward the outer end of the waterproof connector 3, but also facilitating the cable to reset after displacement;

[0037] To sum up, when the present application is in use, the distance between a pair of mounting plates 22 is controlled by controlling the length of the end of the inclined plate 14 away from the waterproof joint 3 extending from the through hole 13, so that personnel can fix cables of different thicknesses. When the cable is pulled by external force, under the action of the elastic force of the tension spring 7, it will pull the cable, making it difficult for the cable to continue moving and facilitating the cable to reset after displacement.

[0038] The second implementation method:

[0039] This implementation mode adds the following structure based on the first implementation mode, and the rest of the structure is consistent with the first implementation mode, as follows:

[0040] Figure 1 and Figure 3 It is shown that a circular groove is opened at one end of the waterproof joint 3 away from the insulating shell 2, and a sealing ring 20 is fixedly connected to the inside of the circular groove by bolts. The sealing ring 20 can improve the sealing between the circular groove and the inflatable ring 21. The inflatable ring 21 is fixedly connected to the inner wall of the sealing ring 20, and the inflatable ring 21 is provided with an air inlet and an outlet. The inflatable ring 21 is detachable. When the inflatable ring 21 is damaged, the sealing ring 20 is taken out from the circular groove and the inflatable ring 21 is replaced.

[0041] After connecting a cable whose outer diameter is smaller than the interface of the waterproof connector 3 into the waterproof connector 3, the inflatable ring 21 needs to be inflated to expand it until its inner wall fits with the outer end of the cable. The inflatable ring 21 is used to clamp the cable to improve the stability of the cable and improve the sealing between the cable and the waterproof connector 3.

[0042] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
