Portable ground wire gun auxiliary operation trailer

Abstract

The invention relates to a portable ground wire gun auxiliary operation trailer. The portable ground wire gun auxiliary operation trailer comprises a bottom frame with the bottom provided with a plurality of wheels. Each of the left side and the right side of the top of the bottom frame is vertically provided with a lifting beam in a sliding manner. A beam is connected to the position, close to the middle portions of the bottom ends of the two lifting beams, between the two lifting beams. A first oil cylinder used for driving the beam to ascend and descend is arranged between the bottom of thebeam and the top of the bottom frame. A sliding plate driven by the first motor is arranged at the position, close to the top end portions of the lifting beams, between the two lifting beams in the front-back direction in a sliding manner. A folding frame driven by a second motor is arranged at the middle portion of the sliding plate and provided with a supporting groove used for erecting a ground wire gun rod. An electric push rod used for driving a trigger to act is arranged at the bottom of a ground wire gun. The portable ground wire gun auxiliary operation trailer is simple in structure,convenient to achieve, capable of saving time and labor during operation and high in automation degree, and the problem of operation of large-specification ground wire guns is thoroughly solved.

Description

technical field [0001] The invention relates to the field of power transformation operation and maintenance tools, in particular to a portable ground gun auxiliary operation trailer. Background technique [0002] The ground wire loader (commonly known as "ground wire gun" or "loader and unloader") is required for the installation and removal of high-voltage equipment. It has been partially disclosed in the Chinese invention patent of ", and its specific structure includes an insulating sleeve or sleeve, a chuck, a pull rod, an operating trigger, a driving rack, a positioning mechanism, and a reset mechanism. Wherein, the collet includes three openable claws, and the claws are slidably installed on the top of the casing through the fixing piece. In a natural state, the three claws protrude from the top of the casing to keep the collet in an open state. The driving rack is vertically slid and installed at the bottom of the casing. The operating trigger is controlled by the pr...

AI Technical Summary

Problems solved by technology

[0005] 1) The installation location is different. When installing or removing the grounding wire, the chuck must constantly adjust the installation direction, so that the operator must continuously adjust the grounding gun from front, back, left, right, up and down so that The jaws can be aligned with the installation position, which greatly consumes the physical strength of the operator and prolongs the operation time;

[0006] 2) The equipment for installing the grounding wire is different. During the process of installing or removing the grounding wire, the clamp size of the grounding wire needs to be adjusted to adapt to the different sizes of the equipment. In this way, it is necessary to continuously operate the trigger of the loader through the handle to adjust the clamping of the grounding wire Size and clamping force, pressing the trigger by hand requires high grip strength and high labor intensity. If the number of loading and unloading ground wires is large, the operator cannot independently bear such a high labor intensity, and multiple people need to take turns to operate, which consumes a lot of labor. and low work efficiency;

[0007] 3) The voltage level of the on-site equipment in the substation is different, and the insulation distance, equipment volume and height are different. Therefore, the length of the ground wire gun is different, that is, the length of the ground wire gun casing is long or short, and the length of the high voltage level is very long. The length of the lower voltage level is shorter, and the short ground gun is relatively easy to operate, but if the voltage level of the device is high, the length of the ground gun body is longer, which will cause the upper part of the ground gun to be clamped after the ground wire clip is clamped. The weight is too heavy, and the operator cannot lift the ground wire gun to the installation position by personal strength. However, two people cannot participate in the power substation operation and maintenance switching operation, so the ground wire operation at high voltage level cannot rely on the ground. The completion of the wire gun must be assisted by an insulated bucket truck, which greatly increases the difficulty, time and cost of the operation
