Description

Technical Field

[0001] The invention relates to the technical field of jumper wires, in particular to a custom tool for electric welding steel pipe jumper wires. Background Art

[0002] During the construction of electric welded steel pipes, ground jumpers are required at the pipe connection locations to ensure the reliability and safety of the electrical connection. In the actual electric welded steel pipe connection, in order to better achieve electrical conduction and connection stability, the middle part of the jumper wire needs to be bent so that it can better fit the surface of the steel pipe or adapt to a specific installation layout to ensure good contact and conduction of the electrical connection. Secondly, by setting the bending part, the elasticity and adaptability of the jumper wire can be increased, and when it is affected by certain external forces or environmental changes, there can be a certain deformation buffer space, reducing the risk of damage caused by stress concentration.

[0003] The traditional method of making jumper cables is usually cumbersome and lacks specialized tools to efficiently and accurately customize jumper cables. Generally, workers may need to manually bend and perform other operations to make jumper cables, but this can easily lead to irregular shapes of jumper cables, and manual operation is inefficient and difficult to meet the needs of large-scale construction. At the same time, in actual applications, there may be different requirements for parameters such as the width of the bend of the jumper cable, and manual operation cannot control the width of the bend.

[0040] Compared with the prior art, the present invention has the following beneficial effects: the present invention places the jumper body 3 in the positioning ring 20202, and presses the steel pipe body 20103 sleeved in the sleeve 20102 downward, thereby bending the jumper body 3. The operation is simple, and batch customization is possible, thus achieving efficient and standardized production. The threaded adjustment rod 215 is driven to rotate by twisting the handle 216, thereby achieving synchronous contraction of the first pressure plate 208 and the second pressure plate 210, and the width of the jumper body 3 being bent can be flexibly changed, so that the processed jumper body 3 can adapt to a variety of different steel pipes, thereby enhancing the practicability of the device. The materials required for the tool are common and easily available, and the production is simple and convenient, thus having a wide range of applicable value.

[0041] Working principle:

[0042] Step 1: Insert the jumper wire body 3 into the two positioning rings 20202;

[0043] Step 2: Connect the adjustment plate 213 to the first pressing plate 208 and the second pressing plate 210, and connect the first pressing plate 208 and the second pressing plate 210 to the connecting plate 204;

[0044] Step 3: When the bending width of the jumper body 3 needs to be changed, the handle 216 is twisted to rotate the threaded adjustment rod 215, thereby causing the first pressing plate 208 and the second pressing plate 210 to shrink synchronously, changing the area directly in contact with the jumper body 3, and adjusting the width of the bending portion of the jumper body 3;

[0045] Step 4: Put one end of the steel pipe body 20103 into the sleeve 20102;

[0046] Step 5: Grasp the other end of the steel pipe body 20103 and press it downward, thereby driving the connecting plate 204, the first pressing plate 208 and the second pressing plate 210 to move downward to bend the jumper wire body 3;

[0047] Step 6: Lift the other end of the steel pipe body 20103 and take out the jumper wire body 3.

[0048] Insert the jumper wire body 3 into the positioning rings 20202 at both ends. The positioning rings 20202 can prevent the jumper wire body 3 from tilting too high at both ends during the bending process. Insert one end of the steel pipe body 20103 into the sleeve 22, and press downward by grasping the other end of the steel pipe body 20103 to drive the connecting plate 204, the first pressure plate 208 and the second pressure plate 210 to move downward to bend the jumper wire body 3.

[0049] When the width of the bending part of the jumper wire body 3 needs to be changed, the handle 216 is rotated to drive the threaded adjustment rod 215 to rotate. Since the threaded adjustment rod 215 is self-locking and threadedly connected with the slider 217, the threaded adjustment rod 215 will drive the slider 217 to move in the left and right directions when it rotates. When the slider 217 moves, it will squeeze the connecting rod 218 to make it swing. Since the connecting rod 218 is respectively hinged to the first pressing plate 208 and the second pressing plate 210, and two groups are arranged in a front-to-back symmetrical distribution, the rotation of the two groups of connecting rods 218 will drive the first pressing plate 208 and the second pressing plate 210 to open or contract synchronously, thereby The area in direct contact with the jumper body 3 is changed to adjust the width of the bending part of the jumper body 3. The arc surface design of the first pressure plate 208 and the second pressure plate 210 can avoid damage to the jumper body 4 during the bending process, and the two are connected by a slider 217. When separated, the slider 217 can fill the gap to prevent the middle part of the jumper body 3 from being pressed out with a bulge. After the jumper body 3 is bent, move the jumper body 3 forward or backward to disengage one end of it from the single-sided positioning ring 20202, and then disengage the other end from the other side of the positioning ring 20202 in the same way to complete the disassembly.

Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
