Description

Technical Field

[0001] The utility model relates to the technical field of wire clamps, in particular to a wire clamp for power transmission and transformation line equipment. Background Art

[0002] Wire clamps are iron or aluminum metal accessories that can be fixed on wires. Most of them need to withstand large tensile forces during operation, and some must also ensure good electrical contact. Wire clamps are mainly divided into: equipment wire clamps, fusible wire clamps, wire holding clamps, terminal wire clamps, piercing grounding wire clamps, tightening wire clamps, insulation piercing wire clamps, double-headed wire clamps, lead-in wire clamps, etc.

[0003] In a Chinese utility model with publication number CN219918358U, a new energy-saving suspension wire clamp is disclosed, which is provided with a pair of U-shaped pressure rods sliding in the height direction of a boat-shaped carrier, the bottom ends of the two U-shaped pressure rods are fixedly connected by a connecting part, and an adjusting part is provided between the connecting part and the boat-shaped carrier, and the adjusting part enables the two U-shaped pressure rods to slide in the height direction of the boat-shaped carrier. When the staff removes or installs the wires, the two U-shaped pressure rods can be moved in the height direction of the boat-shaped carrier by using the adjusting part, so that the difficulty of installing and removing the wires is greatly reduced, and the work of the staff is easier and more convenient.

[0004] Although the device can complete the synchronous lifting and lowering movement of the two U-shaped pressure bars through the adjusting member, the adjusting member will also impose some restrictions on the U-shaped pressure bar. The U-shaped pressure bar will limit the upper part of the bearing member, and the cable can only be installed in the bearing member by passing through, while the already laid cable is difficult to be installed on the bearing member. To this end, we provide a power transmission and transformation line equipment wire clamp to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-3 As shown, the utility model provides a technical solution: a wire clamp for power transmission and transformation line equipment, comprising a load-bearing member 1, a pressing assembly and a lifting plate 13.

[0026] Two groups of guide grooves 6 are provided on the load-bearing member 1 . The two groups of guide grooves 6 are respectively located at two ends of the load-bearing member 1 . A connecting assembly for installing the load-bearing member 1 is provided on the load-bearing member 1 .

[0027] The connecting assembly includes two connecting parts 2 fixedly connected to the load-bearing member 1 and a fixing bolt 4 arranged above the load-bearing member 1. Both connecting parts 2 are provided with through holes 3 matching the fixing bolts 4. One end of the fixing bolt 4 can be passed through the two connecting parts 2 in sequence and installed on the fixing surface, thereby completing the fixation of the load-bearing member 1.

[0028] Two positioning nuts 5 are threadedly connected to the fixing bolt 4, and the two positioning nuts 5 are respectively located on the side of the two connecting parts 2 away from each other. The two positioning nuts 5 can limit the position of the load-bearing member 1 on the fixing bolt 4, and the load-bearing member 1 can drive the connecting part 2 to rotate on the fixing bolt 4, so that the load-bearing member 1 can be adjusted according to the laying angle of the cable.

[0029] The pressing assembly includes a pressing member 7 disposed in the load-bearing member 1, and two pressing rods 9 disposed on the load-bearing member 1. One end of the pressing rod 9 is fixedly connected to a connecting plate 10, and a space is left between the other end of the pressing rod 9 and the connecting plate 10. The side of the pressing member 7 close to the load-bearing member 1 is arc-shaped, which can cooperate with the inner wall of the load-bearing member 1 to complete the clamping of the cable, and can move the cable to the pressing rod 9 and the connecting plate 10 through the space left between the pressing rod 9 and the connecting plate 10. The structure of the components

[0030] The guide groove 6 matches the pressing rod 9, and an arc groove 8 matching the pressing rod 9 is opened on the pressing piece 7. The pressing piece 7 can be positioned on the load-bearing piece 1 through the guide groove 6, and the arc groove 8 can increase the contact area between the pressing rod 9 and the pressing piece 7, thereby ensuring the extrusion effect of the pressing rod 9 on the pressing piece 7.

[0031] The lifting plate 13 is arranged below the load-bearing member 1, and the two ends of the lifting plate 13 are respectively located above the two connecting plates 10. The load-bearing member 1 is provided with a lifting component for lifting and moving the lifting plate 13. The lifting plate 13 can squeeze the two connecting plates 10 downward at the same time, thereby achieving the effect of synchronously controlling the downward movement of the two pressing rods 9.

[0032] The lifting assembly includes a mounting seat 11 fixedly connected to the load-bearing member 1, an adjusting bolt 12 rotatably connected to the mounting seat 11, a lifting plate 13 threadedly connected to the adjusting bolt 12, a guide rod 15 slidably connected to the lifting plate 13, one end of the guide rod 15 is fixedly connected to the mounting seat 11, and the other end of the guide rod 15 is fixedly connected to the limiting plate 16.

[0033] By rotating the adjusting bolt 12 on the mounting seat 11 , the lifting plate 13 can be moved downward under the guidance of the guide rod 15 , and the limiting plate 16 can limit the movement of the lifting plate 13 on the guide rod 15 .

[0034] Both ends of the lifting plate 13 are fixedly connected with pins 14, and a positioning hole 17 matching the pin 14 is opened on the connecting plate 10. When the lifting plate 13 drives the pin 14 to move downward, it can be inserted into the positioning hole 17, thereby making the connection between the lifting plate 13 and the connecting plate 10 more secure.

[0035] Working principle: First, place the load-bearing member 1 at the bottom of the cable, then cover the pressing member 7 on the top of the cable, then pass one end of the fixing bolt 4 through the two through holes 3 in turn and install it on the fixing surface, and the positioning of the load-bearing member 1 can be completed by adjusting the position of the positioning nut 5 on the fixing bolt 4, then, place the structure formed by the two pressing rods 9 and the connecting plate 10 on the cable through the space left therein, then move the pressing rod 9 on the load-bearing member 1 to the guide groove 6, and make the arc groove 8 on the pressing member 7 be below the pressing rod 9, at this time, the positioning hole 17 is located below the latch 14 Finally, by rotating the adjusting bolt 12 through a tool, the lifting plate 13 can be moved downward under the guidance of the guide rod 15, and the connecting plate 10 can be driven downward after the pin 14 is inserted into the positioning hole 17, so that the pressing rod 9 pushes the pressing member 7 downward through the arc groove 8, and the cable is fixed between the load-bearing member 1 and the pressing member 7. The split pressing assembly can not only synchronously drive the two pressing rods 9 to move downward through the lifting plate 13, but also facilitate the placement of the cable in the load-bearing member 1, so that the device can be applied to both installation environments before and after the cable is laid.
