Abstract

The invention relates to a charged bolt fastening special tool, which is characterized in that the special tool comprises two parts, wherein, one part is a lower clamping head which is used for preventing a bolt from rotating; the other part is an upper clamping head which is used for fastening the bolt; the upper clamping head is characterized in that the head part of an insulating rod is connected with a rotary connector through a bolt and a nut; a connecting pipe is also connected with the rotary connector through a bolt and a nut; a lengthened jack wrench is inserted in the connecting pipe; the sleeve of the wrench is sleeved in the lengthened jack wrench; and an angle-variable supporting plate is hinged with the connecting plate of the connecting pipe; the lower clamping head is characterized in that the joint is mounted at the head part of a lower insulation rod through a bolt and a nut; an anti-turning device is further mounted on the lower insulation rod; and the joint is provided with a wrench. The special tool has the advantages of light weight, convenient movement, safe use and the like. As maintenance personnel can inspect and repair electric power equipment without climbing high or getting close to the equipment, the special tool further has the advantages that the economic loss caused by power failure is reduced; and the economic and social benefits are remarkable.

Description

A kind of charged fastening bolt specific purpose tool
Technical field
The invention belongs to electric power maintenance equipment and instrument, specifically a kind of charged fastening bolt specific purpose tool.
Background technology
At the 110---220KV of power supply department transforming plant primary equipment, as switch, CT, PT lead-in wire etc., becoming flexible of these equipment will cause heating, and often breaks down.Main cause has: 1, contact-making surface oxidation; 2, the excessive lead-in wire of wind-force wave cause loosening; 3, bolt quality; 4, ply-yarn drill (surface irregularity, contact-making surface is below 80%) of poor quality.Its consequence is the heating of lead-in wire ply-yarn drill, the processing that needs to have a power failure (this fault has more the peak power supply phase in summer now).With a 110KV line outage 2 hours was example, and the loss of outage that every processing once causes is 30,000 KWh, directly bigger economic loss.For the maintenance of power equipment, existing general utility tool as all kinds of spanners, uses these instruments to need power equipment to have a power failure, and needs the maintainer to ascend a height and near equipment, just can overhaul, and operating efficiency is low like this, the also normal power supply of influence.Develop a kind of charged fastening bolt specific purpose tool for the ease of needs.
Summary of the invention
Order of the present invention is the power equipment maintenance and repair for power supply department, provides a kind of simple in structure, and easy to use can charged fastening bolt specific purpose tool.
Technical scheme of the present invention to achieve these goals is:
A kind of charged fastening bolt specific purpose tool is characterized in that being made up of two parts, and a part has been the following dop that prevents that bolt from rotating, and another part is the upper chuck that is used for fastening bolt; Described upper chuck comprises insulating bar, rotational connector, tube connector, bolts and nuts, the very heavy spanner of lengthening, wrench socket, varied angle gripper shoe; The head of described insulating bar connects rotational connector with bolts and nuts, tube connector also connects rotational connector with bolts and nuts, the very heavy spanner that extends is inserted in the tube connector, and wrench socket is inserted on the very heavy spanner of lengthening, and the varied angle gripper shoe is hinged on the connecting plate on the tube connector; Described dop down comprises insulating bar, joint, anti-rotation device; Adorn a joint at described insulating bar head by bolts and nuts, described anti-rotation device is contained in down on the insulating bar, has wrench socket on the described joint.The described joint and the wrench socket of dop down can be made into one.
Outstanding substantial characteristics of the charged fastening bolt specific purpose tool of the present invention and obvious improvement are:
1, have in light weight, conveniently moving, advantage such as safe in utilization,
Though 2 scientific and technological contents are not high, under the situation of normal power supply, do not need the maintainer to ascend a height and, just can carry out the maintenance of power equipment near equipment, in production reality, can play a significant role.As certain substation equipment maintenance and repair work area take place altogether this type of fault 6 this, handle through using this instrument, obtain good result.
3, guarantee the power supply of power equipment, reduce the economic loss that causes because of power failure, economic and social benefit is remarkable.
Description of drawings
Fig. 1 is upper chuck structural representation among the present invention;
Fig. 2 is following dop structural representation among the present invention.
The specific embodiment
Describe in detail below in conjunction with accompanying drawing:
The charged fastening bolt specific purpose tool of the present invention is made up of two parts, and a part has been the following dop that prevents that bolt from rotating, and another part is the upper chuck that is used for fastening bolt.
As shown in Figure 1, upper chuck comprises insulating bar 1, rotational connector 7, tube connector 9, bolts and nuts 10, the very heavy spanner 5 of lengthening, wrench socket 6, varied angle gripper shoe 8; The head of described insulating bar connects rotational connector with bolts and nuts, tube connector also connects rotational connector with bolts and nuts, the very heavy spanner that extends is inserted in the tube connector, and wrench socket is inserted on the very heavy spanner of lengthening, and the varied angle gripper shoe is hinged on the connecting plate on the tube connector.
As shown in Figure 2, following dop comprises insulating bar 1, joint 2, anti-rotation device 3, wrench socket 6; Described joint is contained in the insulating bar head by bolts and nuts, and described anti-rotation device is contained in down on the insulating bar, and anti-rotation device can be adjusted height arbitrarily on the insulating bar of following dop, and wrench socket is loaded on the joint.The described joint and the wrench socket of dop down also can be made into one, a kind of fastening maintenance of bolts and nuts of specification on the so only suitable electrical equipment, and the wrench socket of the split type replacing different size of joint and wrench socket just can be suitable for the fastening and maintenance of the bolts and nuts of all size on the electrical equipment.
The using method of the charged fastening bolt specific purpose tool of the present invention
At first, the insulating bar of dop makes down dop that bolt or nut on the electrical equipment of required maintenance are blocked under one personal hand-held, then, another person also is placed in the electrical equipment top nut or bolt of required maintenance the wrench socket of upper chuck, and the varied angle gripper shoe is supported on certain point of electrical equipment, at this moment the very heavy spanner of the insulating bar of hand-held upper chuck swing lengthening, get final product screw bolt and nut on the fastening electrical equipment, make that screw bolt and nut obtains fastening on the loosening electrical equipment, finish service work, thereby guarantee that electrical equipment normally moves.
