Description

Technical Field

[0001] The utility model relates to the technical field of railway construction machinery, and particularly relates to a rail welding vehicle with the ability to weld adjacent lines and the line itself. Background Art

[0002] At present, when sporadic rail replacement and on-site welding operations for joint fractures are required for railway rails in China, the following construction methods are mainly adopted:

[0003] 1) Cut the rail to be replaced on-site on this line, manually move the old rail to both sides of the line where it does not affect operation, manually move the new rail to the welding position, adjust the relative position of the rail and the joint, use thermite welding, and use thermite welding agent to weld the rail.

[0004] 2) A container-type rail welding vehicle with a welding machine arranged at the end of the vehicle, which has welding and normalizing functions. After the skylight is closed, the tractor, rail transport vehicle and container rail welding vehicle are grouped and run to the rail to be replaced, hoist the new rail to the relevant position, and drive to other positions. Manually remove the rail fasteners at both ends of the rail joint, cut the rail to be replaced on-site on this line, manually move the old rail to both sides of the line where it does not affect operation, manually move the new rail to the welding position, adjust the relative position of the rail and the joint, and the container rail welding vehicle is slowly pushed by other powered tractors to the welding joint, and the leg device is used to lift the rails on both sides of the joint and slope them. Then, welding and normalizing operations are carried out. After the operation is completed, the rail is placed on the sleeper, the fasteners are restored, the container rail welding vehicle is then towed to the next joint, and serial operations are performed. Finally, after the operation is completed, the formation is restored and the old rail is recovered by the rail transport vehicle, and the rail replacement and old rail recovery are completed within one skylight point.

[0005] 3) The Chinese patent document "A Railway Mobile Rail Welding Vehicle" (Patent No. ZL201920864709.4) discloses a rail welding vehicle or a gas pressure welding vehicle with an end protruding for welding and heat treatment. Its operation mode is similar to that of a container rail welding vehicle, and it has its own power and does not require other tractors to be equipped.

[0006] Under the above welding construction modes, the following deficiencies exist:

[0007] 1) When welding rails by thermite welding, its welding quality is greatly affected by the skill level of operators, the welding quality is uncontrollable, and the rail breakage rate is extremely high, and it has been gradually phased out by gas pressure welding and flash welding.

[0008] 2) Container rail welding vehicles or powered pneumatic rail welding vehicles or flash rail welding vehicles are used on this line, which requires the removal of existing line rail fasteners, cutting of rail joints, manual replacement of rails, rail pads, welding and heat treatment of rail welding vehicle legs, joint grinding, fastener restoration, rail recycling and other operations. The operation requires a large amount of manual cooperation and has low labor efficiency; welding requires legs and rail pads, and the vehicle needs to move back and forth multiple times and cross-operate. The current construction process is complicated and the safety risk is high; when using pneumatic welding, dangerous goods such as acetylene are also required, and their use, transportation and storage are all risky; during operation, only one joint can be completed before going to the next joint, and serial operation has low utilization rate of the entire skylight and low operation efficiency. Utility Model Content

[0009] In view of the defects existing in the prior art, the purpose of the utility model is to provide a rail welding vehicle with the ability to weld adjacent lines and this line, which can weld the rail joints of this line and the rail joints of the adjacent line. A carport is loaded on a flat car, in which a power system, a welding machine system, etc. are arranged, and a crane device is arranged on the other part of the flat car, which can hoist the welding machine to the rail joint of this line, or the adjacent line rail joint of the high-speed railway line, for joint welding and heat treatment. The utility model can make multiple rail fasteners dismantle, replace, and track at the same time when the high-speed railway line is sporadically changed, reduce the cross-operation of man and machine, and greatly improve the efficiency of on-site welding. The entire rail welding vehicle does not run on the line where the fasteners are removed, and there is no need to perform rail padding operations under the vehicle, reducing the safety risks of on-site operations. Further, it can be considered to increase the adjacent line rail retracting and releasing device, which can place new rails at the place to be welded when adjacent to the line, and recycle the replaced rails, which can greatly reduce the number of manual laborers and improve the efficiency of on-site operations and skylight utilization.

[0010] To achieve the above purpose, the technical solution adopted by the utility model is: a rail welding vehicle with the ability to weld adjacent lines and the main line, including a flat car, on which a carport, a crane and a welding machine system are provided; the crane is used to hoist the welding machine system to the adjacent line rail welding joint and / or the main line rail welding joint for welding operations.

[0011] On the basis of the above technical solution, the welding machine system includes a welding machine head and a welding machine protective cover arranged outside the welding machine head.

[0012] On the basis of the above technical solution, the welding machine protective cover includes a slide mechanism and a protective cover frame; the slide mechanism is arranged on a flat car, the protective cover frame is slidably arranged on the slide mechanism, and a door body is arranged on the side of the protective cover frame, and the door body is connected to the protective cover frame by a hinge, and the door body is opened to facilitate the welding machine head to enter and exit; a locking pin is arranged at the lower end of the protective cover frame for fixing the protective cover frame when the vehicle is running.

[0013] On the basis of the above technical solution, the crane includes a slewing mechanism, a luffing mechanism, a telescopic mechanism, and a hoisting mechanism.

[0014] On the basis of the above technical solution, a power storage battery, an inverter cabinet, a normalizing power supply cabinet, an electric control cabinet, a hydraulic power station, a cooling unit, an air compressor, a normalizing air cylinder, a toolbox, and a spare parts cabinet are arranged in the shed.

[0015] On the basis of the above technical solution, an air conditioner is arranged on the top of the shed, glass windows are arranged on the side of the shed, and an end door is arranged at the end of the shed.

[0016] On the basis of the above technical solution, the flat car includes a frame. Couplers are arranged at both ends of the frame, a running gear is arranged at the bottom of the frame, a tread ladder is arranged on the side of the frame, and a braking system is arranged inside the frame.

[0017] On the basis of the above technical solution, a support device is arranged at the bottom of the frame, and the support device is located directly below the crane.

[0018] The beneficial effects of the present utility model are as follows:

[0019] The rail welding vehicle with adjacent line and own line welding functions of the present utility model solves the problems that during sporadic rail replacement at the railway site, when thermite welding is used and manual welding is performed, the welding quality is unstable, the rail breakage rate is relatively high, and it brings great potential safety hazards to the line operation, and improves the on-site rail welding quality.

[0020] The utility model can perform parallel operations when sporadic rails on the high - speed rail line are fractured or severely worn and need to be replaced, separate the rail welding vehicle from the on - site operation personnel, increase the on - site operation efficiency, reduce the interaction time between people and vehicles, and enhance the safety performance of on - site operations. Its operation mode is as follows: The rail welding vehicle and the rail receiving flat car of the utility model run to the vicinity of the rail joint of the adjacent line, hoist the new rail to the welding position, and hoist and recycle the old rail. After the rails are aligned, the rail welding vehicle hoists the welding machine head to the joint for welding operations. After the welding operation is completed, the rail welding vehicle runs to the next joint for operation. Compared with traditional existing rail welding, which can only perform welding operations on the same line and requires processes such as piece - by - piece removal and piercing of fasteners, rail cutting, old rail movement, new rail replacement, rail support at the joint, tightening of some fasteners, joint alignment, movement of the rail welding vehicle to the joint for welding operations, rail joint grinding, movement of the rail welding vehicle to the next welding joint, removal of rail support, and restoration of fasteners, there are a large number of man - machine cross - operations and high on - site operation risks. The rail welding vehicle of the utility model can perform the removal, replacement, and alignment of rail fasteners at multiple locations simultaneously, reduce man - machine cross - operations, and greatly improve the on - site welding efficiency. The entire rail welding vehicle does not run on the line where fasteners have been removed, and there is no need to perform rail padding operations under the vehicle, reducing the on - site operation safety risks. According to the current situation, for sporadic rail replacement at one construction point within a skylight period of 3 hours, only 2 pairs of joint welds, 4 new rails laid, 4 old rails replaced and recycled, and fastener removal and tightening can be completed, and 40 people are required for cooperation. Using the rail welding vehicle of the utility model, more than 4 pairs of joint replacements can be completed within the same skylight time. Cooperating with the rail receiving flat car, only 20 people are required for cooperation, greatly improving the operation efficiency and skylight utilization rate, and significantly reducing manual labor and labor costs.
