Description

Technical Field

[0001] The utility model relates to the technical field of lightning protection grounding jumper wire processing, in particular to a grounding down conductor bending device. Background Art

[0002] In the long-term operation of high-voltage transmission lines, the safety role of the grounding grid cannot be ignored. Generally speaking, in the lightning protection grounding system of high-voltage transmission lines, the components must be connected into an electrical path. When the grounding bus encounters an obstacle and needs to be connected across, a lightning protection grounding down conductor is used. Since the towers are generally high, grounding down conductors are required when the towers are built. Grounding down conductors can effectively prevent lightning and leakage, and can effectively protect the equipment or transmission cables installed on the towers. Nowadays, common grounding down conductors usually use galvanized grounding down conductors, mainly galvanized round steel and galvanized flat steel. Galvanized round steel is usually used when conditions permit.

[0003] When laying the grounding grid, the unsightly production of the grounding down conductor is a common quality problem of the line project. The previous treatment method was to compare and print it with the foundation and the protective cap, and then manually bend it, hit it with a sledgehammer, or oxy-weld it. The efficiency of manual bending and oxy-welding is very low, time-consuming and labor-intensive, and this treatment method is limited by the operator's sense of responsibility and operating level, and the operation is not easy. Manual bending is time-consuming and has low efficiency. A sledgehammer can easily damage the galvanized layer on the surface of the grounding grid. Under external operating conditions, it is easy to cause the grounding grid to rust and break in a short time, affecting the safe operation of the line, and it is easy to hurt people, posing a safety hazard; manual bending.

[0004] In addition, although there are electric steel bar bending machines in the construction industry, some existing bending devices have complex structures and some have simple structures, but none of them are suitable for the bending requirements of grounding down conductors in high-voltage transmission lines in power systems.

[0005] In view of this, the present application provides a simple and easy-to-operate grounding down conductor bender. Utility Model Content

[0033] The present invention is further described in detail below with reference to the accompanying drawings and embodiments:

[0034] like Figure 1 As shown, a grounding down conductor bender comprises a base plate 1 fixedly mounted on a rail 5, a baffle plate 2 arranged on one side of the upper end of the base plate 1, a baffle column 3 arranged on one side of the end of the baffle plate 2 close to the center position of the base plate 1, and a crank 4 inserted in the baffle column 3 and rotatable; the crank 4 is provided with an insertion rod 41 which can be inserted in the baffle column 3 and a baffle rod 42 arranged inside the insertion rod 41; the insertion rod 41 is arranged at the front end of the crank 4.

[0035] Further, such as Figure 2 As shown, the bottom plate 1 is configured as a rectangular parallelepiped structure, and a plurality of mounting holes 11 are arranged around it.

[0036] Further, such as Figure 2 As shown, one mounting hole 11 is provided at each diagonal position of the bottom plate 1 , and the bottom plate 1 is fixedly mounted on the ballast 5 by means of nails, or by means of bolts and nuts.

[0037] Furthermore, one mounting hole 11 is provided around the bottom plate 1 , respectively. The bottom plate 1 can be fixedly mounted on the rail 5 by nails, or the bottom plate 1 can be mounted on the rail 5 by bolts and nuts.

[0038] Further, such as Figure 2 As shown, the blocking column 3 is configured as a round tube with an upper opening; the inserting rod 41 is configured as a cylinder; and the inner diameter of the round tube is greater than the outer diameter of the inserting rod 41 .

[0039] Specifically, the bottom end of the round tube is welded to the upper plane of the bottom plate 1, and the height of the round tube can be set to be consistent with the height of the baffle 2. The outer diameter of the plug rod 41 can be slightly smaller than the inner diameter of the round tube to ensure that the plug rod 41 can rotate flexibly in the round tube. The wall thickness of the round tube needs to ensure the strength of use.

[0040] Further, such as Figure 3 As shown, the insertion rod 41 and the blocking rod 42 are arranged in parallel and have the same height; the distance between the insertion rod 41 and the blocking rod 42 is greater than the diameter of the grounding down conductor 6, so that the blocking rod 42 can rotate with the grounding down conductor 6 when the crank 4 rotates. The blocking rod 42 can be welded with a steel bar head to ensure the strength of the grounding down conductor 6 when it is bent.

[0041] Furthermore, the baffle plate 2 is arranged parallel to the long side of the bottom plate 1 , and one end of the baffle plate 2 is located at the center of the bottom plate 1 .

[0042] Furthermore, the distance between the baffle 2 and the baffle column 3 is greater than the diameter of the grounding down conductor 6 .

[0043] Specifically, the bottom of the baffle 2 is welded on the bottom plate 1, and the baffle 2 must be vertically arranged with respect to the bottom plate 1. The baffle column 3 is arranged at the end of the baffle 2 close to the center of the bottom plate 1, and the distance from the baffle 2 is greater than the diameter of the grounding down conductor 6, that is, the grounding down conductor 6 can be smoothly placed between the baffle 2 and the baffle column 3.

[0044] Further, such as Figure 4-6 As shown, several positions to be bent are marked on the grounding down conductor 6. The positions to be bent are marked on the grounding down conductor 6 according to the shape of the protective cap foundation. After all the grounding down conductors 6 are bent, they are transported to the construction site for direct installation. Figure 7 As shown, the grounding down conductor 6 can be closely fitted to the base of the protective cap, thus avoiding the problem of inconvenient bending or unsightly bending on site.

[0045] Furthermore, the above-mentioned base plate 1, baffle plate 2, baffle column 3, crank handle 4, plug rod 41, baffle rod 42, etc. are all made of carbon structural steel Q235, high carbon steel or stainless steel.

[0046] Grounding down conductor bender processing method:

[0047] (1) Press baffle 2 Figure 1 The position shown is welded on the bottom plate 1, as shown in FIG. Figure 2 As shown;

[0048] (2) Press the stopper 3 Figure 1 The position shown is welded on the bottom plate 1, as shown in Figure 2 As shown; when the diameter of the grounding down conductor 6 changes, the distance between the baffle 3 and the baffle 2 can be set farther;

[0049] (3) Fix the bottom plate 2 on the end surface of the rail 5 by nails or bolts. Figure 1 As shown;

[0050] (4) A cylindrical plug rod 41 is welded to one end of the crank 4, and a stop rod 42 is welded to the inner side of the plug rod 41. The distance between the plug rod 41 and the stop rod 42 is slightly larger than the diameter of the grounding down conductor 6. When the diameter of the grounding down conductor 6 changes, the distance between the plug rod 41 and the stop rod 42 can be adjusted, that is, the stop rod 42 can be welded farther away from the plug rod 41, such as Figure 3 shown.

[0051] How to use the grounding down conductor bender:

[0052] like Figure 4-6 As shown, one operator places the grounding down conductor 6 between the baffle 2 and the stop column 3, and another operator operates the crank 4 to insert the plug 41 into the stop column 3, and clamps the grounding down conductor 6 between the plug 41 and the stop rod 42 according to the marked bending position of the grounding down conductor 6. The crank 4 is turned to rotate the grounding down conductor 6 around the stop column 3 until it is bent to the required angle, which is generally a right angle. After the grounding down conductor 6 is fully bent according to the shape of the protective cap base 7, it is cut off and then transported to the installation site for installation. Figure 7 As shown, the grounding down conductor 6 can be closely fitted to the base of the protective cap, thus avoiding the problem of inconvenient bending or unsightly bending on site.

[0053] In summary, the grounding down conductor made by the grounding down conductor bending device provided by the utility model has beautiful craftsmanship, saves time and labor, is easy to operate, and can complete three times the workload in the same number of working days.
