Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of a method for replacing a sliding contact line in a corrosive area. BACKGROUND

[0002] With the development of science and the continuous improvement of industrial technology, mobile equipment, cranes, vehicles and other equipment with fixed tracks are widely used in production areas such as factories. However, when the sliding contact line needs to be replaced in a corrosive area such as an emulsion plant or an acid washing plant, the bolts of the hanging clamp are severely corroded due to severe corrosion, and the sliding contact line cannot be replaced by normal disassembly through the bolts.

[0003] In non-corrosive areas, the sliding contact line is generally replaced by loosening the bolts, thereby replacing the hanging clamp and the sliding contact line inside it. Since the nuts and screws are now generally made of metal, the screw can easily be rotated out of the nut in a normal environment. However, since the nut and screw are in a corrosive area, the nut and screw are solidified as one, and the screw is difficult to rotate out of the nut. Therefore, when replacing the sliding contact line in such a corrosive area, after protecting the overhead bridge of the sliding contact line, the bolts are generally cut off by a welding tool or a cutting machine for replacement. Since the sliding contact line is generally three parallel and close to the overhead bridge, the cutting process is time-consuming and labor-intensive, the working position is limited, and the construction efficiency is affected.

[0004] Therefore, a construction method for replacing a sliding contact line in a corrosive area is designed to avoid the use of oxyacetylene welding in high-altitude field operations, improve the safety and quality of construction, improve construction efficiency, and save costs. It belongs to the field of metallurgical production. SUMMARY

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the present application is to provide a method for replacing a sliding contact line in a corrosive area to solve the problem of reduced construction efficiency caused by the use of oxyacetylene welding in high-altitude field operations in the prior art.

[0006] To achieve the above-mentioned purposes and other related purposes, the present application provides a method for replacing a sliding contact line in a corrosive area, comprising:

[0007] A sliding contact line support is provided on the support of the crane track, and the sliding contact line support nut screw connects the hanging clamp. The hanging clamp is provided with a sliding contact line.

[0008] The replacement method comprises the following steps:

[0009] Step S1: cutting the part of the sliding contact line support connected with the nut screw from the hanging clamp by a cutting method;

[0010] Step S2: cutting off the bolt screw rod by cutting method, removing the bolt screw rod;

[0011] Step S3: setting a new hanging clamp with slide wire, fixing it to the slide wire support by the new bolt screw rod.

[0012] Preferably, the cutting method in step S1 can cut the slide wire support by a cutting machine.

[0013] Preferably, the cutting method in step S2 can melt and break the bolt screw rod by welding.

[0014] Preferably, a gap is provided between the slide wire in the hanging clamp and the bottom of the nut screw rod.

[0015] As described above, the corrosion area slide wire replacement method of the present application has the following beneficial effects:

[0016] The method of the present application reduces the total construction time by cutting off the hanging clamp first and then cutting the nut screw rod, increases the construction efficiency; at the same time, since the cutting of the nut screw rod is accelerated, the use time of oxyacetylene welding is reduced, and the cost is reduced.

Any modification of the structure, change of the proportional relationship, or adjustment of the size, without affecting the effects and purposes that can be achieved by the present application, should still fall within the scope of the technical content disclosed by the present application. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are merely for the purpose of clear understanding of the description, and are not used to limit the scope of the present application. The change or adjustment of the relative relationship, without substantially changing the technical content, is also considered as the scope of the present application.

[0025] As shown in Figure 1 The present application provides a method for replacing a corrosion area sliding contact line, which comprises:

[0026] A sliding contact line support 12 is arranged on the support of the crane track, and the sliding contact line support 12 is connected to the hanging clamp 3 through the nut screw 2; the hanging clamp 3 is provided with the sliding contact line 31.

[0027] The replacement method comprises the following steps:

[0028] Step S1: cutting the part of the sliding contact line support 12 connected to the nut screw 2 from the hanging clamp 3 by cutting method.

[0029] Step S2: cutting the bolt screw 2 by cutting method, and removing the bolt screw 2.

[0030] Step S3: setting a new hanging clamp 3 with the sliding contact line 31, and fixing it to the sliding contact line support 12 through the new bolt screw 2.

[0031] Through the replacement method, the hanging clamp 3 can be cut open by cutting method, and the bolt screw 2 can be cut off from the sliding contact line support 12 again; the hanging clamp 3 is fixed and connected to the sliding contact line support 12 through the new nut bolt 2; the difficulty coefficient of directly cutting the bolt screw 2 in the air is avoided, the labor amount is reduced, and the work efficiency is improved; under the construction method, the same work amount can be completed within 24 hours by the same personnel, which requires 36 hours under the original 200m distance construction.

[0032] Since the hanging clamp 3 is made of plastic, and is cut by welding method, the plastic may be melted, which may affect the health of the operator; therefore, the cutting method by using the cutting machine can not only reduce energy consumption, but also quickly complete the cutting of the hanging clamp 3 under the condition of ensuring operation safety.

[0033] Although the hanging clamp 3 with the slide wire 31 is taken off, the corroded nut screw 2 is still in the mounting hole used for connecting the hanging clamp 3 with the slide wire support 12; therefore, in order to take out the nut screw 2, the nut screw 2 needs to be cut open and then taken out.

[0034] In order to accelerate the cutting speed of the nut screw 2, the nut screw 2 can be separated by using the welding method; then, a new hanging clamp 3 is re-installed, and the hanging clamp 3 is fixed to the slide wire support 12 through the new nut bolt 2.

[0035] In summary, the method of the present application reduces the total construction time and increases the construction efficiency by preferentially cutting off the hanging clamp and then cutting the nut screw again; at the same time, the cutting speed of the nut screw is accelerated, the use time of the oxyacetylene welding is reduced, and the cost is reduced.

[0036] Therefore, the present application effectively overcomes the various shortcomings in the prior art and has a high industrial utilization value.

[0037] The above embodiments only exemplarily illustrate the principles and effects of the present application, and are not used to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the present application should be covered by the claims of the present application.
