Description

Technical Field

[0001] This utility model relates to the field of suspension clamp technology, and in particular to a suspension clamp with an automatic limiting mechanism. Background Technology

[0002] Suspension clamps are used to fix conductors to insulator strings on straight-line towers, or to suspend lightning protection wires on straight-line towers. They can also be used to support transposed conductors on transposed towers and to fix jumpers on tension angle towers.

[0003] For example, CN106532609A discloses a suspension clamp with an automatic limiting mechanism, which includes a grooved shell, a grooved buckle plate that mates with the grooved shell, guide ridges distributed on the two outer sides of the grooved buckle plate, guide grooves that mate with the guide ridges distributed on the inner side of the grooved shell that mates with the grooved buckle plate, fixing ears provided at both ends of the grooved shell, a clamping plate hinged in the fixing ears, an eccentric wheel rotatably mounted at the bottom end of the clamping plate, and the longest wheel edge of the eccentric wheel abutting against the upper end of the grooved buckle plate.

[0004] In the existing technology, when the suspension clamp is used to fix the line, the line will be subjected to external forces such as wind deflection and conductor galloping, which will cause the conductor to deflect excessively, resulting in the distance between the conductor and the pole or other objects being less than the safe distance. At the same time, the conductor will slip and wear within the suspension clamp, and may even break strands, which will accelerate the damage to the hardware and reduce its service life. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that the line is subject to external forces such as wind deflection and conductor galloping, which can cause the conductor to deflect excessively, resulting in the distance between the conductor and the tower or other objects being less than the safe distance. The invention proposes a suspension clamp with an automatic limit mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a suspension clamp with an automatic limiting mechanism, comprising a suspension clamp hull, a positioning mechanism installed on one side of the suspension clamp hull, and an anti-deviation mechanism installed on the inner side of the suspension clamp hull. The anti-deviation mechanism includes a fixed sleeve plate, a positioning frame fixedly connected to one end of the fixed sleeve plate, a steering plate rotatably connected to the inner side of the positioning frame, an abutment strip abutting one end of the steering plate, a fixed connection of one end of the abutment strip to the other end of the fixed sleeve plate, a telescopic rod fixedly connected to the inner side of the steering plate, an anti-deviation plate fixedly connected to one end of the telescopic rod, and a compression spring sleeved on the outside of the telescopic rod, the compression spring being installed between the steering plate and the anti-deviation plate.

[0007] Preferably, a second elastic pad is fixedly connected to the inner ring surface of the anti-deviation plate.

[0008] Preferably, the outer surface of the fixing sleeve is fixedly connected to the inner side of the suspension clamp hull, and a first elastic pad is fixedly connected to the inner ring surface of the fixing sleeve.

[0009] Preferably, the positioning mechanism includes a positioning plate, with positioning blocks fixedly connected to both ends of the positioning plate, one side of the two positioning blocks abutting against one side of the steering plate, and a U-shaped ring sleeved on one side of the suspension line clamping the hull.

[0010] Preferably, a limiting pad is fixedly connected to one side of the positioning plate, and the other side of the positioning plate is engaged with the bend of the U-shaped ring.

[0011] Preferably, both ends of the U-shaped ring are fitted with elastic collars, one side of the elastic collar is abutted against a fixing nut, and the inner ring surface of the fixing nut is threadedly connected to the outer surface of the U-shaped ring.

[0012] Preferably, clamps are fixedly connected to both sides of the hull of the suspension clamp, and a connecting rod is installed between the two clamps.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the cable is placed on the inner ring surface of the first elastic pad, and the steering plate is rotated to make it abut against the abutment strip. The second elastic pad abuts against the outer surface of the cable. Within the normal working range, the compression spring is in its natural state. When the suspension clamp body deflects significantly, the compression spring will generate elastic force, which will drive the telescopic rod to retract and apply a reverse force to the suspension clamp body, so that it returns to the normal working position. This can limit the deflection angle of the cable, avoid excessive movement of the suspension clamp body, reduce wear and fatigue of the wire and hardware, and extend the service life.

[0015] 2. In this utility model, both ends of the two U-shaped rings pass through one side of the suspension clamp hull, and the positioning blocks abut against the outer surfaces of the two steering plates respectively. The U-shaped rings are fixed by moving the fixing nuts, so that the limiting pads abut against the outside of the cable, thereby fixing the suspension clamp hull to the outside of the cable, which can effectively fix the cable and prevent the cable from shifting and swinging.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a suspension clamp with an automatic limiting mechanism, including a suspension clamp hull 1. A positioning mechanism 3 is installed on one side of the suspension clamp hull 1, and an anti-deviation mechanism 2 is installed on the inner side of the suspension clamp hull 1. The anti-deviation mechanism 2 includes a fixed sleeve plate 21, one end of which is fixedly connected to a positioning frame 29. A steering plate 27 is rotatably connected to the inner side of the positioning frame 29. One end of the steering plate 27 abuts against an abutment strip 25, and one end of the abutment strip 25 is fixedly connected to a fixed... At the other end of the fixed sleeve plate 21, a telescopic rod 26 is fixedly connected to the inner side of the steering plate 27. One end of the telescopic rod 26 is fixedly connected to an anti-deviation plate 24. A compression spring 28 is sleeved on the outside of the telescopic rod 26. The compression spring 28 is installed between the steering plate 27 and the anti-deviation plate 24. A second elastic pad 23 is fixedly connected to the inner ring surface of the anti-deviation plate 24. The outer surface of the fixed sleeve plate 21 is fixedly connected to the inner side of the suspension line clamp hull 1. A first elastic pad 22 is fixedly connected to the inner ring surface of the fixed sleeve plate 21.

[0024] First, flip the steering plate 27 outward to place the cable on the inner ring surface of the first elastic pad 22. Then, rotate the steering plate 27 so that one end of the steering plate 27 abuts against the abutment strip 25. At this time, the second elastic pad 23 set on the inner side of the anti-deviation plate 24 abuts against the outer surface of the cable. Within the normal working range, the compression spring 28 is in its natural state and does not significantly hinder the movement of the suspension clamp body 1. When the suspension clamp body 1 deflects significantly, the compression spring 28 will generate elastic force, which will drive the telescopic rod 26 to retract and apply a reverse force to the suspension clamp body 1, so that it returns to the normal working position. This can limit the deflection angle of the cable, avoid excessive movement of the suspension clamp body 1, reduce wear and fatigue of the wire and hardware, and extend the service life.

[0025] Example 2: Figure 1 , Figure 2 and Figure 3 As shown, the positioning mechanism 3 includes a positioning plate 34, with positioning blocks 36 fixedly connected to both ends of the positioning plate 34. One side of each positioning block 36 abuts against one side of the steering plate 27. A U-shaped ring 33 is sleeved on one side of the suspension clamp hull 1. A limit pad 35 is fixedly connected to one side of the positioning plate 34, and the other side of the positioning plate 34 is engaged with the bend of the U-shaped ring 33. Elastic collars 38 are sleeved on the outside of both ends of the U-shaped ring 33. A fixing nut 37 abuts against one side of the elastic collar 38. The inner ring surface of the fixing nut 37 is threadedly connected to the outer surface of the U-shaped ring 33. Clamps 32 are fixedly connected to both sides of the suspension clamp hull 1, and a connecting rod 31 is installed between the two clamps 32.

[0026] When the cable is passed through the suspension clamp hull 1, the anti-deviation mechanism 2 can limit the cable. Both ends of the two U-shaped rings 33 are passed through one side of the suspension clamp hull 1, so that the outer side of the positioning plate 34 is engaged with the bend of the two U-shaped rings 33. The positioning blocks 36 at both ends of the positioning plate 34 abut against the outer surface of the two steering plates 27 respectively. The elastic collar 38 is put on the outside of the U-shaped ring 33, and the fixing nut 37 rotates on the external thread of the U-shaped ring 33, so that the fixing nut 37 moves to fix the U-shaped ring 33, so that the limiting pad 35 abuts against the outside of the cable, thereby fixing the suspension clamp hull 1 to the outside of the cable, which can effectively fix the cable and prevent the cable from deviating and swinging.

[0027] The usage and working principle of this device are as follows: First, flip the steering plate 27 outward, and place the cable on the inner ring surface of the first elastic pad 22, so that one end of the steering plate 27 abuts against the abutment strip 25. At this time, the second elastic pad 23 abuts against the outer surface of the cable. When the cable passes through the suspension clamp body 1, the anti-deviation mechanism 2 can limit the cable. Both ends of the two U-shaped rings 33 pass through one side of the suspension clamp body 1 and are fixed. The positioning plate 34 is engaged with the two U-shaped rings 33, so that the limiting pad 35 abuts against the outside of the cable, thereby fixing the suspension clamp body 1 to the outside of the cable. Within the normal working range, the compression spring 28 is in a natural state and does not significantly hinder the movement of the suspension clamp body 1. When the suspension clamp body 1 deflects significantly, the compression spring 28 will generate elastic force, which will drive the telescopic rod 26 to retract and apply a reverse force to the suspension clamp body 1, so that it returns to the normal working position.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
