Description

Technical Field

[0001] This utility model relates to the field of power transmission line support technology, and in particular to a power transmission line adjustment support frame. Background Technology

[0002] With my country's rapid development, the demand for power transmission is increasing. For example, the construction of subways and high-speed railways will lay a large number of power transmission lines. These power transmission lines are usually laid in conjunction with support frames. The role of the support frames is to support the high-voltage conductors and overhead ground wires in the power transmission lines, so that these lines can be suspended in the air to avoid contact with the ground or other obstacles and ensure the safe transmission of electricity.

[0003] The existing support frame is fixed in one position by pre-embedding. Generally, multiple sets are set in layers at one position to allow the transmission line to be laid in layers. However, the gaps between these multiple sets of support frames are set in advance and fixed, so it is difficult to adjust the gaps between the support frames. When encountering a thicker transmission line, the gap between two support frames is insufficient and it cannot be laid.

[0004] Therefore, how to provide a transmission line adjustment support frame is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide a power transmission line adjustment support frame, which solves the problem that the spacing between two sets of existing support frames is difficult to adjust.

[0006] According to an embodiment of the present utility model, a power transmission line adjustment support frame includes a mounting plate and a support frame. The mounting plate is embedded in the wall by a pre-embedded part. A sliding component is provided inside the mounting plate. A locking component is provided on the sliding component to lock the position of the sliding component. A connector is fixedly connected to the side of the sliding component. The connector is installed on the side of the support frame.

[0007] The sliding assembly includes two guide grooves for guidance, and a guide plate is movably connected inside the mounting plate, with both ends of the guide plate slidably connected inside the guide grooves.

[0008] The mounting plate has a toothed groove on its inner wall. The locking assembly includes a through groove and a flexible rod. The through groove is located on the surface of the guide plate, directly above the connector. The top of the flexible rod is fixedly connected to the top of the inner wall of the through groove. A clip is fixedly connected to the side of the flexible rod near the bottom. The clip engages with the inside of the toothed groove. A locking assembly is provided on the other side of the flexible rod near the bottom.

[0009] The locking assembly includes a positioning seat and a locking block. The positioning seat is fixedly connected to the surface of the guide plate at a position directly above the through groove. The locking block is fixedly connected to the side of the flexible rod away from the locking head. A positioning pin is movably inserted into the interior of the positioning seat. The bottom end of the positioning pin passes through the positioning seat and the locking block and extends to the bottom of the locking block.

[0010] The positioning seat has a rubber pad for pressing the positioning pin fixedly connected inside, and a limit protrusion is fixed on the side of the positioning pin away from the guide plate.

[0011] The support frame has a slot at the top and a limiting top bracket at the top. The bottom end of the limiting top bracket is movably inserted into the slot. A threaded hole communicating with the outermost slot is provided on the side of the support frame away from the connector. A positioning bolt for positioning the limiting top bracket is threaded into the inside of the threaded hole. One end of the positioning bolt extends to the surface of the limiting top bracket.

[0012] The beneficial effects of this utility model are:

[0013] By setting up a sliding component and a locking component, the sliding component slides within the mounting plate to drive the mounting frame to move up and down via the connector, and the locking component locks the position of the sliding component. Thus, the position of the support frame is locked by the sliding component and the connector, achieving the effect of adjusting the height of the support frame and solving the problem that the spacing between the two sets of support frames is difficult to adjust.

[0014] By setting a limiting top frame, the top of the transmission line is limited, so that the transmission line is stably placed on the support frame. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] refer to Figure 1 It includes a mounting plate 1 and a support frame 2, wherein the mounting plate 1 is embedded in the wall by pre-embedded parts;

[0022] Example 1

[0023] The mounting plate 1 is internally provided with a sliding assembly 3, which includes two guide grooves 6 for guidance. The two guide grooves 6 are vertically arranged along both sides of the inner wall of the mounting plate 1. A guide plate 7 is movably connected inside the mounting plate 1. Both ends of the guide plate 7 are slidably connected inside the guide grooves 6. The width of the two end faces of the guide plate 7 matches the width of the guide grooves 6, thus preventing the guide plate 7 from shaking inside the guide grooves 6. A connector 5 is fixedly connected to the side of the guide plate 7. The connector 5 is installed on the side of the support frame 2. The support frame 2 is fixed to the guide plate 7 through the connector 5, so that the support frame 2 is fixed in a horizontal position. During operation, the support frame 2 is moved, so that the support frame 2 drives the guide plate 7 to slide up and down inside the groove through the connector 5, thereby realizing the height adjustment of the guide plate 7.

[0024] Example 2

[0025] The sliding assembly 3 is provided with a locking assembly 4 for locking its position. The inner wall of the mounting plate 1 has toothed grooves 8, which are horizontally opened and vertically arranged. The locking assembly 4 includes a through groove 9 and a flexible rod 10. The flexible rod 10 is a high-toughness metal rod with excellent springback after bending. The through groove 9 is located on the surface of the guide plate 7, directly above the connector 5. The top end of the flexible rod 10 is fixedly connected to the top of the inner wall of the through groove 9. A locking head 11 is fixedly connected to the side of the flexible rod 10 near its bottom end, and the locking head 11 engages inside the toothed groove 8. The guide plate 7 in section 3 moves up and down, causing the flexible rod 10 and the clamp 11 to move up and down. When the clamp 11 moves, it is squeezed by the tooth groove 8 and moves away from the tooth groove 8 and separates from the tooth groove 8. The movement of the tooth groove 8 causes the flexible rod 10 to bend inside the through groove 9. When the support frame 2 reaches the appropriate height, the clamp 11 will mesh with the tooth groove 8 in other positions through the rebound force of the flexible rod 10. In this way, the position of the guide plate 7 will be locked in advance through the clamp 11 and the flexible rod 10. Then, the guide plate 7 will lock the height of the support frame 2 in advance through the connector 5, thus achieving the effect of adjusting the height of the support frame 2.

[0026] Example 3

[0027] A locking assembly 12 is provided on the other side of the flexible rod 10 near its bottom end. The locking assembly 12 includes a positioning seat 13 and a locking block 14. The positioning seat 13 is fixedly connected to the surface of the guide plate 7, located directly above the through groove 9. The locking block 14 is fixedly connected to the side of the flexible rod 10 away from the locking head 11. A positioning pin 15 is movably inserted into the interior of the positioning seat 13. A rubber pad 16 for pressing the positioning pin 15 is fixedly connected inside the positioning seat 13. A limit protrusion 17 is fixed on the side of the positioning pin 15 away from the guide plate 7. The bottom end of the positioning pin 15 passes through the positioning seat 13 and the locking block 14 and extends to the bottom of the locking block 14. The guide plate 7 locks the locking head 11 and the flexible rod 10 one step ahead to prevent the locking head 11 from separating from the tooth groove 8. This positioning assembly is provided. When the locking head 11 is engaged in the tooth groove 8, the opening on the locking block 14 will align with the opening on the positioning seat 13. Then, the positioning pin 15 on the positioning seat 13 will move downward so that the bottom end of the positioning pin 15 is inserted into the locking block 14 to lock the position of the locking block 14. After the position of the locking block 14 is locked, when the locking head 11 is squeezed, the force is transmitted to the locking block 14 through the tough rod 10. Since the position of the locking block is locked, the tough rod 10 is not easy to bend. In this way, the locking head 11 can be stably locked in the tooth groove 8, ensuring that the guide plate 7 is not easy to slide under force. If the guide plate 7 is not easy to slide under force, the connecting piece 5 and the support frame 2 are also not easy to slide, thereby locking the position of the support frame 2 and achieving the effect of locking the adjusted position of the support frame 2.

[0028] Example 4

[0029] The support frame 2 has a slot 18 on its top. The slot 18 is located on the protruding part of the support frame 2 to avoid the location of the power transmission line. The support frame 2 has a limiting top frame 19 on its top. The limiting top frame 19 blocks the top of the support frame 2 and is used to stably limit the power transmission line on the support frame 2. The bottom end of the limiting top frame 19 is movably inserted into the inside of the slot 18. On the side of the support frame 2 away from the connector 5, there is a threaded hole 20 that communicates with the outermost slot 18. The threaded hole 20 is threadedly connected to a positioning bolt 21 for positioning the limiting top frame 19. One end of the positioning bolt 21 extends to the surface of the limiting top frame 19. During operation, the limiting top frame 19 is inserted into the slot 18. Then, the distance between the top of the limiting top frame 19 and the support frame 2 is adjusted. After adjustment, the positioning bolt 21 is rotated to lock the limiting top frame 19, thus achieving the effect of limiting the power transmission line on the support frame 2.

[0030] It should be noted that the limiting top bracket 19 needs to be installed when there is sufficient distance between the two support brackets 2. If there is not enough distance between the two support brackets 2, the limiting top bracket 19 is not needed.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
