Description

Technical Field

[0001] This invention belongs to the technical field of railway vehicle equipment, specifically relating to an aerial work platform vehicle suitable for factories and mines. Background Technology

[0002] In the transportation of large-scale industrial and mining materials such as ore and mining machinery, railway transportation has become the mainstream mode of transport due to its significant advantages of high efficiency, low cost, and large carrying capacity. At the same time, the railway overhead contact system, as a core facility ensuring smooth transportation, requires regular maintenance. However, the current power modules of the work vehicles are scattered, requiring separate installation space for each module, occupying more of the vehicle's usable area and hindering the mounting of work equipment. Furthermore, the dispersed distribution necessitates point-by-point inspection for maintenance, increasing disassembly and assembly time and operational complexity. The increased demand for specialized tools also drives up maintenance costs. Therefore, improvements are necessary to address these issues. Summary of the Invention

[0003] The technical problem solved by this invention is to provide an aerial work platform vehicle suitable for factories and mines. By setting a mounting frame at the top right end of the vehicle frame and centrally installing the power pack on the mounting frame, the invention solves the problems of space occupation, inconvenient maintenance, and high maintenance costs caused by the dispersed arrangement of power packs when providing power to the working device in existing vehicles. The invention optimizes the overall structural design, improves operational safety, facilitates maintenance and troubleshooting, and reduces disassembly and assembly time and operational complexity. Furthermore, by setting guardrails on the two long sides of the vehicle frame, with both ends fixedly connected to the canopy and the mounting frame respectively, the risk of workers accidentally falling while working on the metal floor of the vehicle frame can be reduced. The fully enclosed protection at all locations effectively improves operational safety.

[0004] The technical solution adopted in this invention is as follows: an aerial work platform vehicle suitable for factories and mines, including a frame for supporting all components and a walking system located at the bottom of the frame. An iron floor is laid flat and welded to the outdoor position of the upper surface of the frame, and a wooden floor is laid inside the canopy welded and fixed to the left end of the upper surface of the frame. The canopy is equipped with a berth for workers to rest and a video system equipment cabinet.

The long side of the frame is equipped with a guardrail with one end fixed to the side corresponding to the canopy and the other end fixedly connected to one side of the mounting frame.

[0005] The working device includes an aerial work platform for installing, dismantling, and adjusting the upper part of the contact wire and an operating cabinet for operating the aerial work platform.

[0006] Furthermore, the power pack includes a diesel engine with a built-in generator, an intake system, an exhaust system, a cooling system for cooling the diesel engine, and a coupling. The intake system is connected to the intake port of the diesel engine and provides filtered and clean intake air to the diesel engine. The exhaust system is connected to the exhaust port of the diesel engine and discharges exhaust gas with reduced noise. The flywheel end of the diesel engine is connected to a hydraulic pump for driving the working device through a coupling, and the hydraulic pump provides the required power source to the working device. The mounting bracket is equipped with a protective cover for enclosing the various parts of the power pack inside.

[0007] Furthermore, the braking system installed on the frame includes an air braking system, a basic braking device, and a manual braking device located on the outside of the canopy.

[0008] Furthermore, a locking device is provided between the bogie axle box and the frame in the travel system, and the working device locks the car body and bogie by the locking device when it is working.

[0010] Advantages of this invention compared to existing technologies: 1. This technical solution integrates the power pack, including the diesel engine, intake system, exhaust system, cooling system, and coupling, onto a mounting frame. Compared to the traditional distributed layout, this significantly reduces space occupation, saves effective vehicle body area, and provides more space for the mounting of working devices and other equipment. At the same time, the integrated design makes the inspection and maintenance of the power pack more convenient, eliminating the need for point-by-point troubleshooting, reducing disassembly and assembly time and operational complexity, and lowering the demand for special tools and maintenance costs. 2. This technical solution has protective railings at both ends of the two long sides of the frame that are fixedly connected to the canopy and the mounting frame, which can effectively prevent workers from accidentally falling when working on the iron floor of the frame. The full protection of each position effectively improves the safety of the operation. 3. The braking system of this technical solution includes a triple protection system of air braking system, basic braking device and manual braking device to ensure the safety of vehicle operation and parking; during operation, the frame and bogie are locked by a primary locking device to prevent vehicle displacement, ensure the stability of high-altitude operation and further improve the safety of operation.

[0020] In this structure, the power pack 6 is integrated and mounted on the mounting bracket 4 on the right side of the top surface of the frame 1, providing power support for the working device 5. The internal diesel engine 6-1 has its own generator. The intake system 6-2 is connected to the intake port of the diesel engine 6-1, filtering and cleaning the air entering the engine through components such as filters to prevent impurities from entering the engine and causing wear. The exhaust system 6-3 is connected to the exhaust port of the diesel engine 6-1, using components such as mufflers to reduce noise pollution at the work site. The cooling system 6-4 uses a radiator to dissipate the heat generated by the diesel engine 6-1 during operation, ensuring the engine operates at a suitable temperature. The flywheel end of the diesel engine 6-1 is connected to the hydraulic pump via a coupling 6-5. The hydraulic pump converts the mechanical energy of the diesel engine 6-1 into hydraulic energy to power the working device. The action of 5 provides the power source; although the cooling system 6-4, exhaust system 6-3 and intake system 6-2 in the power pack 6 are existing components installed and fixed with the diesel engine 6-1, the optimization of the specific installation position makes the structure more compact. There is no need to plan separate installation areas for each component of the power pack 6, which frees up the effective space of the iron floor of the frame 1, which can be used to carry the working device 5 or other auxiliary equipment, and is more suitable for the limited space of the factory and mine operation site and the need for compact equipment layout; the flywheel end of the diesel engine 6-1 is connected to the hydraulic pump through the coupling 6-5, which shortens the power transmission path, reduces energy loss, and ensures a stable power supply for the lifting, extension and retraction of the aerial work platform 5-1, which is suitable for the stringent requirements of the operation accuracy of the factory and mine contact network maintenance.
