Description

An auxiliary installation tool for grounding down conductors

technical field

The utility model relates to the technical field of transmission line construction, in particular to an auxiliary installation tool for grounding down conductors.

Background technique

With the vigorous development of my country's electric power construction industry, the amount of tower erection projects is increasing, and the corresponding construction rules and regulations are constantly being supplemented and improved, and the construction standards are increasing day by day. According to the requirements of the high-quality power transmission and transformation project of the State Grid Corporation, the grounding wire of the tower is drawn from the grounding hole, and after being led to the cement foundation along the tower leg, it should be attached to the surface of the foundation. Therefore, the grounding wire needs to be checked twice during construction. The bending operation makes the grounding wire fit the horizontal plane and the vertical plane of the cement foundation respectively.

In the current actual construction, there is still a lack of reasonable bending devices. The construction personnel can only use self-made crude devices and rely on manpower to operate. Quality, and the device is heavy, it is inconvenient to carry when carrying out mountain construction.

For example, the Chinese patent announcement number is: CN206597851U, a portable hydraulic pole tower ground wire bending machine announced on April 13, 2017, including a main rod and a lever, and the main rod includes a bending die head and a bending die The hydraulic device connected to the back side of the head, the handle connected to the rear side of the hydraulic device, the bending die head is provided with a bending die groove, and the hydraulic device is equipped with a hydraulic system, a piston, a pressure rod and a control hydraulic pressure The stop valve of the system, the lever is hinged at the fulcrum of the hydraulic device, and connected to the piston through the connecting rod, the lever is repeatedly pressed down and the piston is stretched through the connecting rod, so that the hydraulic system drives the pressure rod to extend forward, and the pressure The rod head cooperates with the bending die groove to complete the bending of the grounding wire. Although this bending machine can greatly save the physical strength of the construction workers, it is difficult to accurately control the operating force, and it is easy to damage the galvanized layer of the grounding wire, reducing the construction quality. , and the bending machine is inconvenient to carry.

The purpose of this utility model is mainly achieved by the following scheme: an auxiliary installation tool for grounding down conductors, including an operating rod and a cross bar arranged on one end of the operating rod, the cross section of the cross bar is square , the middle part of one side of the cross bar is provided with two limit rods along the width direction, a limit gap is formed between the two limit rods, and both ends of the cross bar are rotatably connected with rollers. The roller and the limit rod are arranged on the same side, and the roller is provided with a bending groove along the circumferential direction. The cross section of the cross bar is square, and the cross bar is a square tube. The middle part of one side of the cross bar is provided with two limit rods along the width direction. A limit gap is formed between the two limit rods, and the grounding wire passes through the two Between the limit rods and placed in the limit gap, both ends of the cross bar are rotatably connected with rollers, the rollers and the limit rods are arranged on the same side, and bending grooves are arranged on the rollers along the circumferential direction. During specific operations, Move the grounding wire along the bending groove of one of the rollers and pass through the limit gap, and then pass it to the bending groove of the other roller in the opposite direction to the previous roller, so that the grounding wire forms a line on the cross bar "S"-shaped curve, and finally turn the operating lever to bend the grounding wire. The setting of the roller can effectively reduce the damage to the galvanized layer of the grounding wire during bending, improve the process level, and ensure the construction quality.

As a preference, the bottom of the roller is provided with an adjustment groove on the crossbar, the bottom of the roller is rotatably connected with a positioning column located in the crossbar, and the side of the crossbar away from the roller is provided with a Locating bolts for threaded connection of locating posts. The bottom of the roller is provided with an adjustment groove on the cross bar, the bottom of the roller is connected with a positioning post inside the cross bar, and the side of the cross bar away from the roller is provided with a positioning bolt threaded with the positioning post. Move away from the crossbar. At this time, the roller can move to a suitable position along the adjustment groove according to actual needs. After the roller moves to the proper position, turn the positioning bolt to fix the positioning bolt on the crossbar, so that the roller can The position is fixed.

Preferably, an anti-falling ring is provided on the side of the positioning column close to the roller. The side of the positioning column close to the roller is provided with an anti-off ring, and the setting of the anti-off ring makes the stability of the roller move higher, and it is not easy to detach from the cross bar.

Therefore, an auxiliary installation tool for grounding down conductors of the present invention has the following advantages: the utility model is simple to operate, easy to carry, can accurately control the operating force, will not damage the galvanized layer of the grounding wire, and has high construction quality.
