Description

Working platform for mobile vehicle repair and maintenance engineering vehicle

technical field

The utility model belongs to the technical field of mobile automobile repair and maintenance vehicles, in particular to a working platform of a mobile automobile maintenance engineering vehicle.

Background technique

Cars have entered thousands of households, but cars need regular maintenance. The usual way is to drive the vehicle to a 4S shop for maintenance. This method takes time and fuel consumption. However, there are a lot of car repair stations in the streets and alleys, which can easily cause failures. Wrong judgment will affect the normal use of the vehicle. Generally, 4S stores are concentrated in large and medium-sized cities. For car owners in small cities or rural areas, it takes a lot of time and fuel consumption to maintain a car, which creates a burden for car owners. The patent number "A Mobile Vehicle Maintenance and Charging Station" published on the patent website is CN 203876635 U. There are side extension shells with inner openings on both sides of the side extension shell, and the bottom of the side extension shell is slidingly connected with the bottom frame of the car body through the side extension transmission device; four synchronous lifting cylinders are connected to the bottom surface of the maintenance area; There are rear doors, and retractable approach bridges are arranged on both sides below the rear doors; rectangular hydraulic support columns are arranged at the bottom of the main body of the vehicle." The problems of this patent are: 1. It is difficult to find a bus with a front engine. 2. The maintenance area is set on the main body of the bus chassis. It is necessary to drive the vehicle to the maintenance area, which is difficult to achieve due to the steep slope and requires a very professional driver. 3. After the vehicle enters the maintenance area, the basic space on both sides is inconvenient for the maintenance personnel to move, and the maintenance work is basically impossible to carry out. 4. It is difficult to realize the long-distance outward extension of the bus body. 5. Remove the vehicle lifting platform The remaining space is too small to realize office and other tools, accessories, oil storage and operation. 6. If the vehicle to be repaired cannot be driven to the maintenance platform by itself, this patent has no way to move the vehicle to the maintenance platform, and the work cannot be carried out. The patent number published by the patent network is: 201320137006.4 "Passenger Car Mobile Maintenance and Repair Service Vehicle", "The tailgate includes a first tailgate, a second tailgate, and a linked first elevator and second elevator; The first tailgate part is rotatably connected with the box body; the second tailgate part is movably connected with the first tailgate part; the first elevator is arranged on the first tailgate part; the The second lifter is arranged on the second tailgate part." This patent uses the tailgate as a work platform for maintenance, and the length and width of the maintenance work platform are respectively the width and height of the tailgate, which cannot meet the needs of automobiles at all. The space requirement for maintenance is that the length of the vehicle to be repaired is already longer than the length of the working platform of the car. The lift installed on the working platform must be top-heavy to lift the vehicle to be repaired, which is easy to cause the accident of the vehicle slipping. The personal and property of maintenance personnel bring huge potential safety hazards.
