Description

Technical Field

[0001] The utility model relates to a portable disassembly and assembly device for the underbody components of a yard engineering vehicle, belonging to the technical field of special equipment for urban rail transit vehicles. Background Technique

[0002] There are various types of engineering vehicles, which can be divided into rail vehicles, comprehensive inspection vehicles, rail flaw detection vehicles, rail grinding vehicles, flatbed vehicles, etc. according to their structural functions. These vehicles each undertake different functions and tasks. For example, the traction operation vehicle is mainly used for shunting operations within the vehicle depot and traction for train failures on the main line; the inspection operation vehicle is used for the inspection of the technical parameters of the subway contact rail (network) and tracks; and the transportation operation vehicle is mainly used for the transportation of materials. Therefore, the maintenance of engineering vehicles is crucial.

[0003] The maintenance of engineering vehicles includes daily maintenance, fault repair, annual inspection, overhaul, etc. The underbody facilities and equipment of engineering vehicles are an indispensable part of urban rail transit vehicles, directly related to the service life and operation efficiency of the vehicles, and are the key parts to ensure the operation of the vehicles. During the maintenance of the underbody facilities and equipment, the space in the pit is narrow and there are no corresponding auxiliary workpieces. Therefore, in the disassembly and assembly of most underbody facilities and equipment such as the drive shaft, fuel tank of engineering vehicles, inspection module of comprehensive inspection vehicles, and semi-permanent drawbar of rail grinding vehicles, manual handling equipment is still used, resulting in low operation efficiency, high manual labor intensity, and a safety risk of injuring people.

[0004] Currently, about 80% of the underbody maintenance operations of domestic rail engineering vehicles adopt manual disassembly methods, and the remaining 20% use other methods such as double-axis wheel lathes and auxiliary flatbed trolleys for disassembly and assembly. For double-axis wheel lathes, their overall cost is relatively high, and only a few subway industries adopt them, with high procurement costs. For other methods such as Shenzhen Metro, there are auxiliary trolleys, but they only play a role of flat support and cannot stabilize the underbody components, making them inconvenient to use, and still unable to get rid of the need for manual assistance in disassembly. Currently, there is no good working method for the disassembly and assembly of underbody components during the maintenance of underbody components. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is that there is no good working method for the disassembly and assembly of underbody components during the maintenance of underbody components and other technical problems. The utility model proposes a portable disassembly and assembly device for the underbody components of a yard engineering vehicle, which is a movable and portable disassembly and assembly device that can provide functions of fixing equipment, handling equipment, and auxiliary disassembly and assembly when disassembling and assembling underbody equipment such as the drive shaft, fuel tank, inspection module of comprehensive inspection vehicles, and semi-permanent drawbar of rail grinding vehicles. This device can assist in solving the disassembly problems of more than 90% of the underbody components. It solves the situation of manual handling equipment and the lack of professional tools in the underbody disassembly and assembly equipment in the industry, greatly saving labor costs and reducing labor intensity, and significantly improving operation efficiency and safety factor.

[0008] The hydraulic device includes a jacking oil cylinder that drives the scissor lift mechanism to lift through the telescopic movement of the oil cylinder and an oil pump powered by the power system; the movement of the hydraulic oil pump brings about a change in the pump chamber volume, thereby compressing the fluid to make the fluid have pressure energy, enabling the oil cylinder to jack and traverse, with fast speed and high work efficiency; the scissor lift mechanism and the lifting platform are driven by the telescopic movement of the oil cylinder to realize the lifting function.

[0009] A guide rail is installed on the lifting platform, and a detachable execution element that can be replaced according to the working conditions of different engineering vehicles is installed on the guide rail.

[0010] The execution element is an auxiliary device for disassembling and assembling the drive shaft of an engineering vehicle, or an auxiliary device for disassembling and assembling the fuel tank of an engineering vehicle, or an auxiliary device for disassembling and assembling the detection device of a comprehensive inspection vehicle.

[0011] The execution element is one or a combination of a guide wheel set, a front-end annular adjustable support fixture, a front-end flat adjustable support fixture, and a rear-end fixed support frame. These execution elements cooperate together to complete the support function of the device and realize the disassembly and assembly operation of the underbody components.

[0012] It further includes a power supply system and a control system electrically connected to the power supply system. The power supply system consists of a storage battery, and the storage battery is charged using 220V 50Hz, and the full-load continuous use time after being fully charged is ≥ 2 hours. Charging through a 220V 50Hz power supply and being able to be fully loaded and continuously used for at least 2 hours after being fully charged meets the requirements of long-term operation.

[0013] The power supply system includes a storage battery, and the control system includes a control switch and a control circuit. The control system realizes various functions of the device through the control switch and the control circuit. The control switch is designed at the handle of the trolley, which is convenient for the operator to operate at any time and improves the convenience of operation.

[0014] The traveling system includes a handling trolley and rubber solid wheels provided at the four corners under the handling trolley. It has a four-wheel structure, located at the four corners of the handling trolley, with good overall stability and can stop and remain locked at any position. At the same time, it is also designed to be equipped with a motor drive to achieve the function of autonomous walking without manual pushing. It can be increased according to the usage scenario.

[0021] The portable disassembly and assembly device for the underbody components of a depot engineering vehicle provided by the present utility model can implement the lifting and supporting functions for the underbody components of different working conditions by replacing different actuating elements, improving the diversity and adaptability of the operation.

[0022] Eight maintenance personnel are required for manual disassembly. The overall operation depends on the physical strength and skills of the workers and is also limited by individual differences. After equipping with a complete set of equipment for disassembling and assembling the underbody components of a depot engineering vehicle, only two maintenance personnel are required to complete the work, and it is not affected by individual differences, significantly reducing the number of operating personnel.

[0023] Manual disassembly is vulnerable to fatigue and human factors, making it difficult to ensure accuracy. The overall operation duration exceeds 4 hours, resulting in low operation efficiency. After equipping with the complete set of equipment for disassembling and assembling the underbody components of depot engineering vehicles, a special workpiece fixture module is adopted to ensure the accuracy and repeatability of the disassembly and assembly operations. The influence of human factors is reduced, and the operation speed is significantly increased. The operation duration only requires 2 hours. The operation time is significantly reduced, and the efficiency is increased by 100%.

[0024] During manual disassembly, workers directly contact vehicle components, posing safety risks such as falling and impact. The complete set of equipment for disassembling and assembling the underbody components of depot engineering vehicles reduces the direct contact of workers through front and rear end fixtures and safety protection measures, significantly reducing safety risks.
