[0022] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] It should be noted that all components in the technical solution of this application require necessary additional facilities for water supply, oil supply, electricity supply and gas supply for driving and / or control. If there is no further explanation, it is assumed that the existing technology is used and equipped, and no special explanation is required.

[0024] It should be noted that, in order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0025] Depend on Figure 1-4 The adjustable power hardware wire clamp shown includes a pull frame, which is fixedly connected to an external fixed hanger. Two sets of clamps are slidably connected to the bottom end of the pull frame. The clamps include a clamping plate 1, and a push plate 2 is slidably connected inside the clamping plate 1. One end of the push plate 2 clamps the cable with one end of the clamping plate 1, and the other end of the push plate 2 is adapted and slidably connected to a wedge block 3. The wedge block 3 is slidably connected to the bottom end of the pull frame; the push plate 2 is slidably connected to the clamping plate 1.

[0026] A further optimized solution is that the two ends of the splint 1 are C-shaped structures with openings facing each other. The bottom surface of the inner cavity of the splint 1 is fixedly connected with a slide rail 4. The slide rail 4 preferably uses a special-shaped block or a guide block with anti-pullout, which can guide and limit the push plate 2. A first slide groove 5 is provided on the bottom surface of the push plate 2, and the slide rail 4 is slidably connected to the first slide groove 5; a groove is provided at one end of the push plate 2, and one end of the push plate 2 is adapted to one end of the splint 1 to form a clamping groove 6 for placing the cable. The inner wall of the C-shaped opening at both ends of the splint 1 is provided with a number of anti-slip grooves 17, and further, a number of anti-slip grooves 17 are also provided in the groove. By setting the anti-slip grooves 17, the friction between the splint 1 and the push plate 2 and the cable can be increased, thereby improving the fastening force of the cable.

[0027] A further optimization scheme is that the other end of the push plate 2 is chamfered, and the two side surfaces of the wedge block 3 are adapted to and slidably connected to the other end surface of the push plate 2. The cross-section of the sliding guide portion of the wedge block 3 is an isosceles triangle, and the wedge block 3 is pulled by the pull rod 7 to drive the push plate 2. The top surface of the wedge block 3 is fixedly connected to the pull rod 7, and the top surface of the pull rod 7 is fixedly connected to the chuck 8. The pull rod 7 is set through the pull frame. The pull rod 7 and the chuck 8 are respectively slidably connected to the pull frame, and the side surface of the pull rod 7 is adapted to the other end surface of the push plate 2, avoiding the problem of the wedge block 3 sliding out from the other end side of the push plate 2.

[0028] Furthermore, a sliding hole is provided on the bottom surface of the wedge block 3, and a guide column is slidably connected in the sliding hole. The guide column is fixedly connected to the bottom surface of the inner cavity of the splint 1. The wedge block 3 is guided and limited by the guide column, thereby improving the stability of the wedge block 3.

[0029] A further optimized solution is provided, in which the tension frame includes a bow plate 9 and a chord plate 10. The two ends of the bow plate 9 are fixedly connected to the two ends of the chord plate 10, and a second slide groove 11 is provided in the middle of the chord plate 10. The second slide groove 11 is slidably connected to the bottom surface of the chuck 8 on the side of the pull rod 7. A fixing assembly is provided in the center of the chord plate 10. The top of the fixing assembly passes through the bow plate 9 and is fixedly connected to a lifting ring 12. The lifting ring 12 is fixedly connected to an external fixed sling. The fixing assembly includes a fixing rod 13 and a flange 14. The fixing rod 13 is fixedly connected to the flange 14. The fixing rod 13 passes through the second slide groove 11 and the bow plate 9 and is fixedly connected to the lifting ring 12. The fixing rod 13 has a thread on its side. The fixing rod 13 is screwed with a nut 15. The nut 15 and the flange 14 clamp the chord plate 10. The nut 15 is used to press the chord plate 10 against the top surface of the flange 14, thereby achieving a fixed connection of the fixing rod 13.

[0030] Furthermore, the fixing rod 13 passes through the bow plate 9 and is screwed to the bow plate 9, thereby improving the structural stability of the tension frame.

[0031] To further optimize the solution, the fixing rod 13 is slidingly connected to the second slide groove 11, and the top surface of the flange 14 is symmetrically fixedly connected with a protrusion 16, which fits into the side of the chord plate 10. The protrusion 16 is used to limit the chord plate 10 to prevent the chord plate 10 from being deformed due to the movement of the fixing rod 13 or the pull rod 7.

[0032] To further optimize the solution, a rubber layer 18 is provided on the bottom surface of the inner wall of the C-shaped opening at both ends of the splint 1, one end of the rubber layer 18 is fixedly connected to the bottom surface of the inner cavity of the splint 1, and the other end of the rubber layer 18 is detachably connected to the bottom surface of one end of the push plate 2. By pushing up one end of the push plate 2, one end of the rubber layer 18 is completed to squeeze the cable, thereby improving the fixing effect of the cable.

[0033] The working process of this embodiment is as follows:

[0034] Depend on Figure 1-4 As shown, the cable is passed through the clamping groove 6, and the clamping plate 1 is pressed down by the dead weight of the cable. The downward pressure of the clamping plate 1 drives the push plate 2 downward, which will prompt the lifting ring 12 to pull the fixing rod 13 and the flange 14 to remain stationary. At this time, the pull rod 7 and the chuck 8 will pull the wedge block 3. At this time, the downward movement of the push plate 2 and the stability of the wedge block 3 will form a relative movement. The wedge block 3 will drive the push plate 2 to slide sideways to achieve the clamping of the cable. At the same time, when the push plate 2 pushes toward one end of the clamping plate 1, it will shovel up the rubber layer 18 and wrap the cable, which can not only increase the support area on the outside of the cable, but also buffer the mutual friction between the cable and the clamping plate 1.

[0035] Moreover, by adjusting the cable length between the two clamps, the spacing between the clamps can be adjusted, which can improve the ability of the utility model to adapt to complex working conditions, and can increase the fastening nodes, thereby increasing the stress points, reducing the degree of local fatigue wear of the cable, and increasing the service life.

[0036] The above are merely preferred embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
