Description

Technical Field

[0001] The invention relates to the technical field of power tower maintenance, and in particular to an auxiliary tool for repairing a suspension string of hardware for a linear pole tower of a power transmission line. Background Art

[0002] As the voltage level of transmission lines increases, the size of transmission line towers and hardware is getting larger and larger. At present, ice-covered tension sensors are often installed in sections of transmission lines with large spans and heavy ice areas. Due to the complex operating environment and other reasons, they need to be inspected and maintained.

[0003] Due to the large size of the pole tower and the long hardware at the grounding end of the suspended string of the straight pole tower, it is difficult for workers to operate using live working methods. They can only operate by standing on the vertically suspended insulator string during power outages. This has great limitations and affects the power supply of the line. Summary of the invention

[0004] The invention provides an auxiliary tool for repairing a suspension string fitting of a linear pole tower of a power transmission line, and aims to provide an auxiliary tool that can facilitate the repair operation.

[0005] The present invention is achieved through the following technical scheme: an auxiliary tool for repairing the suspension string hardware of a linear pole tower of a transmission line, comprising two vertical rods, a horizontal rod connected between the two vertical rods, and a workbench, the two sides of the workbench are respectively connected to the two vertical rods, one end of the workbench is connected to an abutment plate, the abutment plate is located between the two vertical rods, and the end of the abutment plate away from the workbench is an arc concave surface.

[0006] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0007] When the auxiliary tool in this scheme is in use, the vertical rod is connected to the cross arm at the location to be inspected by a rope, and the abutment plate is inserted between two adjacent insulators in the insulator string. At the same time, the arc concave surface of the abutment plate is abutted against the outer side of the steel cap between the two insulators for support and limitation. The operator squats on the working platform to operate to avoid short-circuiting the insulators.

[0008] The auxiliary tool in this solution enables the operator to work in a live state, and the auxiliary tool is more convenient for maintenance operations and can provide the operator with a support point to facilitate the operator to perform maintenance operations.

[0009] In addition, the insulator strings in the straight pole towers of high-voltage lines are usually large and long, and each insulator is made of glass. The setting of the abutment plate in the present application can limit the entire auxiliary tool, reduce the shaking of the auxiliary tool, improve the safety of the workers during maintenance, and avoid the damage of the insulator caused by the collision of the auxiliary tool with the insulator due to the shaking of the auxiliary tool.

[0010] Furthermore, the two sides of the workbench are respectively hinged to two vertical rods, and a first connecting plate and a second connecting plate are connected between the vertical rods and the workbench. The first connecting plate and the second connecting plate are hinged to each other, and the ends of the first connecting plate and the second connecting plate away from each other are respectively hinged to the vertical rods and the workbench.

[0011] Beneficial effect: In this solution, the workbench is hinged to the two vertical rods, so that it can be folded when the auxiliary tool is not needed, which is convenient for storage and movement. The setting of the first connecting plate and the second connecting plate facilitates the tightening of the workbench when the workbench is unfolded, thereby improving the stability of the workbench and making it easier for operators to work on the workbench.

[0012] Furthermore, the two vertical rods are connected with hinge blocks, and the two sides of the workbench are respectively hinged to the hinge blocks.

[0013] Beneficial effect: In this solution, the hinge block is connected to the vertical rod, which is convenient for hinged installation with the workbench and more convenient to operate.

[0014] Furthermore, both of the vertical rods are telescopic rod structures, and the vertical rods include an inner rod and an outer rod. The inner rod is located inside the outer rod and axially slides with the outer rod. A limiting member for limiting the sliding of the inner rod is installed on the outer rod.

[0015] Beneficial effects: The telescopic rod structure of the vertical rod in this solution is easy to shrink according to actual conditions, the length can be adjusted, it is easy to install on different tower types, and it is more flexible and convenient to use.

[0016] Furthermore, the outer rod is provided with an outer hole, and the inner rod is provided with a plurality of inner holes in sequence along its axial direction, and the limiting member can be inserted into the outer hole and the inner hole that overlap with each other for locking and fixing.

[0017] Beneficial effect: In this solution, the length between the inner rod and the outer rod is changed by sliding the inner rod, and after the outer hole on the outer rod coincides with the inner hole on the inner rod, the position between the inner rod and the outer rod is fixed by locking and fixing through the limit piece to maintain the telescopic state.

[0018] Furthermore, the abutment plate is located in the middle of the workbench, and two sides of the abutment plate are arranged to be inclined inwardly from the workbench to the arc concave surface of the abutment plate.

[0019] Beneficial effect: In this solution, the two sides of the abutment plate are inclined to each other, which can reduce the width of the abutment plate and enhance the stability of the abutment plate, so that the arc concave surface of the abutment plate can smoothly abut on the steel cap of the insulator for support and limitation.

[0020] Furthermore, a limiting plate is hingedly connected to the abutting plate, and the limiting plate is an arc plate. The limiting plate and the arc concave surfaces at the ends of the abutting plate can be engaged with each other.

[0021] Beneficial effect: A limiting plate is also provided in the present scheme. When the limiting plate and the abutment plate are buckled with each other, they can wrap the steel cap on the insulator, so that the abutment plate is not easy to separate from the steel cap during operation, which can improve the limiting effect between the abutment plate and the steel cap, making the entire auxiliary tool more stable and safe, and further reducing the shaking of the auxiliary tool during use.

[0022] Furthermore, a connecting belt is connected to one end of the limiting plate away from the abutment plate, a fixing column is connected to the abutment plate, and a fixing block is connected to one end of the connecting belt away from the limiting plate, a fixing hole is provided on the fixing block, and after the arc concave surfaces of the limiting plate and the ends of the abutment plate are buckled with each other, the limiting plate is limited by inserting the fixing column through the fixing hole on the fixing block.

[0023] Beneficial effect: In this solution, when the limit plate and the abutment plate are buckled together, the position of the limit plate after buckling can be further fixed and limited by inserting it into the fixing column through the fixing hole on the fixing column, so as to avoid the limit plate from detaching from the steel cap during use and affecting the limiting support function between the steel cap, thereby avoiding affecting the stability of the auxiliary tool after installation.

[0024] Furthermore, a groove is provided on the inner side of the limit plate, and a clamping block is provided in the groove for radial sliding engagement with the limit plate. The clamping block is also an arc block, and an elastic member is connected between the clamping block and the side wall of the groove. In a natural state, one side of the clamping block is located outside the groove.

[0025] Beneficial effect: The clamping block in the present solution can be pressed against the steel cap under the action of the elastic member, thereby increasing the friction between the clamping block and the steel cap and avoiding slipping due to a gap between the limiting plate and the steel cap. When the limiting plate and the abutment plate are buckled together, the clamping block can be tightly pressed against the steel cap under the elastic action of the elastic member, thereby further improving the stability between the abutment block and the steel cap, thereby further improving the stability of the entire auxiliary tool.

[0026] Furthermore, a plurality of weight-reducing holes are provided on the workbench.

[0027] Beneficial effect: With such arrangement, the workbench is hollowed out, which can reduce the weight of the workbench, make the auxiliary tools lighter as a whole, and facilitate installation and transportation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary implementation modes of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0038] Example 1

[0039] like Figure 1 As shown, this embodiment 1 provides an auxiliary tool for repairing the suspension string hardware of the straight pole tower of the transmission line, including two vertical poles 1, and a horizontal rod 101 is connected between the two vertical poles 1. The horizontal rod 101 connects the two vertical poles 1 into a whole. In this embodiment, the tops of the two vertical poles 1 are fixedly connected with lifting ears 102. The setting of the lifting ears 102 is convenient for fixing them to the cross arm 13 through ropes at a later time.

[0040] In the present embodiment, an auxiliary tool for repairing the suspension string hardware of the straight pole tower of the transmission line also includes a workbench 2, and the two sides of the workbench 2 are respectively connected to the two vertical rods 1. The workbench 2 and the vertical rods 1 can be fixedly connected or hinged. When the two sides of the workbench 2 are fixedly connected to the vertical rods 1, the two sides of the workbench 2 are respectively welded and fixed to the two vertical rods 1. In the present embodiment, the two sides of the workbench 2 are respectively hinged to the two vertical rods 1. Specifically: the two vertical rods 1 are connected with hinge blocks 6, and the hinge blocks 6 are located at the lower part of the vertical rods 1. The two sides of the workbench 2 are respectively hinged to the hinge blocks 6 through axes. The setting of the hinge blocks 6 facilitates the hinged installation of the workbench 2.

[0041] A first connecting plate 4 and a second connecting plate 5 are connected between the vertical rod 1 and the workbench 2. The first connecting plate 4 and the second connecting plate 5 are hinged to each other. One end of the first connecting plate 4 and the second connecting plate 5 that are away from each other are hinged to the vertical rod 1 and the workbench 2 respectively. A triangular structure is formed among the first connecting plate 4, the second connecting plate 5, the vertical rod 1 and the workbench 2, which can provide a stable support for the workbench 2.

[0042] Combination Figure 2 As shown, in this embodiment, when the construction auxiliary tools are not needed, the workbench 2 can be folded and stored.

[0043] like Figure 1 As shown, in this embodiment, an abutment plate 3 is connected to one end of the workbench 2, the abutment plate 3 is located between the two vertical rods 1, and the end of the abutment plate 3 away from the workbench 2 is an arc concave surface. In this embodiment, the arc concave surface end of the workbench 2 extends to the other side of the vertical rod 1, and the workbench 2 is located on both sides of the vertical rod 1, so that it is convenient to insert the abutment plate 3 between adjacent insulators 120 later.

[0044] In this embodiment, the abutment plate 3 is located in the middle of the workbench 2, and the two sides of the abutment plate 3 are inclined inward from the workbench 2 to the arc concave surface of the abutment plate 3, so that the abutment plate 3 is similar to a trapezoidal shape, which is more convenient to insert between the two insulators 120.

[0045] In this embodiment, a plurality of weight-reducing holes 201 are provided on the workbench 2, and the weight-reducing holes 201 are rectangular through-hole structures. Similarly, a plurality of weight-reducing holes 201 are provided on the abutment plate 3, and the weight-reducing holes 201 on the abutment plate 3 are trapezoidal through-hole structures, so that the weight of the entire workbench 2 can be reduced.

[0046] The specific implementation process is as follows: Figure 5 As shown, an insulator string 12 is usually connected to the cross arm 13. The insulator string 12 consists of a plurality of insulators 120. The end of each insulator 120 is connected to a steel cap 121. Adjacent insulators 120 are connected by the steel caps 121, so that the plurality of insulators 120 are interconnected to form the insulator string 12.

[0047] When using the auxiliary device of this embodiment, the vertical rod 1 is connected to the cross arm 13 at the location to be inspected by passing a rope through the lifting ear 102, and the abutment plate 3 is inserted between two adjacent insulators 120 in the insulator string 12. At the same time, the arc concave surface of the abutment plate 3 is abutted against the outer side of the steel cap 121 between the two insulators 120 for support and limitation. The operator squats on the working platform to operate to avoid short-circuiting the insulators 120.

[0048] The auxiliary tool in this solution enables the operator to work in a live state, and the auxiliary tool is more convenient for maintenance operations, and can provide a support point for the operator to facilitate maintenance operations. When the auxiliary tool is not needed, the workbench 2 can be folded and stored to reduce the storage space.

[0049] Example 2

[0050] like Figure 3 As shown, an auxiliary tool for repairing the suspended string hardware of a straight pole tower of a power transmission line is different from Example 1 in that: in this embodiment, a limit plate 7 is hinged on the abutment plate 3, and the limit plate 7 is an arc plate. In this embodiment, the limit plate 7 is an arc plate larger than half a circle, and the limit plate 7 and the arc concave surfaces at the ends of the abutment plate 3 can be interlocked. When the limit plate 7 and the abutment plate 3 are interlocked, the steel cap 121 can be wrapped, thereby improving the stability of the entire auxiliary tool, reducing the shaking of the auxiliary tool, and thus improving safety.

[0051] In this embodiment, the end of the limiting plate 7 away from the abutment plate 3 is connected to a connecting belt 8, and a fixing column 9 is connected to the abutment plate 3. The fixing column 9 is vertically welded to the upper surface of the abutment plate 3, and the end of the connecting belt 8 away from the limiting plate 7 is connected to a fixing block 801, and a fixing hole is opened on the fixing block 801. After the arc concave surfaces at the ends of the limiting plate 7 and the abutment plate 3 are buckled with each other, the limiting plate 7 is limited by inserting the fixing column 9 through the fixing hole on the fixing block 801. In this embodiment, the connecting belt 8 adopts an elastic belt. When the fixing block 801 is put on the fixing column 9, the connecting belt 8 can be stretched, and the limiting plate 7 and the abutment plate 3 can jointly press the steel cap 121.

[0052] In this embodiment, under the snap-fitting effect of the limit plate 7 and the abutment plate 3, the stability of the entire auxiliary tool after installation can be enhanced, thereby reducing the shaking of the auxiliary tool, further improving the safety of the operation, and further avoiding the risk of collision with the insulator 120 when the auxiliary tool shakes.

[0053] Example 3

[0054] like Figure 4 As shown, an auxiliary tool for repairing the suspension string hardware of the straight pole tower of the transmission line is different from Example 2 in that: in this embodiment, an arc-shaped groove is opened on the inner side of the limit plate 7, and a clamping block 10 is fitted in the groove along the radial sliding direction of the limit plate 7. The clamping block 10 is also an arc block, so that the shape of the clamping block 10 matches that of the limit plate 7, which is convenient for installation and assembly.

[0055] An elastic member is connected between the clamping block 10 and the side wall of the groove. In this embodiment, the elastic member is a spring 11. In a natural state (ie, the elastic member is not compressed), one side of the clamping block 10 is located outside the groove.

[0056] In this embodiment, the clamping block 10 can be displaced along the radial direction of the limit plate 7 under the action of the elastic member, so that it can adapt to steel caps 121 of different sizes. Under the action of the elastic member, when the limit plate 7 and the abutment plate 3 are mutually engaged on the steel cap 121, the clamping block 10 can be tightly against the steel cap 121, thereby improving the stability between the steel cap 121 and further improving the stability of the auxiliary tool after installation.

[0057] Example 4

[0058] like Figure 6As shown, an auxiliary tool for repairing the suspension string hardware of the linear tower of the transmission line is different from the embodiment 1 in that the two vertical rods 1 in the embodiment are telescopic rod structures, and the vertical rod 1 includes an inner rod 104 and an outer rod 103, the inner rod 104 is located inside the outer rod 103 and axially slides with the outer rod 103, and a limiter for limiting the sliding of the inner rod 104 is installed on the outer rod 103. In the embodiment, the workbench 2 is connected to the lower part of the outer rod 103, and the lifting lug 102 is fixed to the end of the inner rod 104.

[0059] In this embodiment, an outer hole 1022 is opened on the outer rod 103, and a plurality of inner holes 1044 are opened in sequence along the axial direction of the inner rod 104. The limiting member can be inserted into the overlapping outer hole 1022 and the inner hole 1044 for locking and fixing. In this embodiment, the limiting member can be a bolt. After the screw is inserted into the overlapping inner hole 1044 and the outer hole 1022, the inner rod 104 and the outer rod 103 can be fixed by a nut. Alternatively, a cotter pin can be used to limit the connection between the inner rod 104 and the outer rod 103.
