Description

Technical Field

[0001] The utility model relates to the technical field of engineering vehicles, in particular to a split-type engineering vehicle rear door which is easy to maintain. Background Art

[0002] The most basic function of engineering vehicles is to be used in earthmoving operations. They can dig, fill, and level the land to build foundations or other facilities that meet the requirements. In addition to earthmoving operations, engineering vehicles can also perform transportation work. In the process of engineering construction, various materials and equipment need to be transported to the corresponding locations. Therefore, large-scale transport vehicles are needed to ensure smooth and efficient transportation. For example, dump trucks can easily and quickly transport large amounts of construction materials or waste materials, thereby ensuring that the site is clean and safe. For this reason, a split engineering vehicle rear door that is easy to maintain is proposed.

[0003] The existing Chinese utility model patent with reference announcement number CN214928885U discloses a rear door of an engineering vehicle that can effectively insulate heat. The rear door of the engineering vehicle that can effectively insulate heat includes a compartment, a hinge is fixedly connected to the front surface of the compartment, and the rear door of the engineering vehicle is fixedly connected to one side of the hinge. The front and rear surfaces of the rear door of the engineering vehicle are both provided with heat-insulating paint, and a hollow layer is opened in the middle of the inner surface of the compartment; during the use of the device, the rear door of the engineering vehicle is closed to start the cooling fan, and the heat passing through the rear door of the engineering vehicle is first reduced by the heat-insulating paint on the front and rear surfaces of the rear door of the engineering vehicle and the asbestos insulation layer inside the rear door of the engineering vehicle. After part of the heat reaches the inside of the hollow layer, the heat dissipation layer on the inner wall of the hollow layer reduces the absorption of heat by the rear door of the engineering vehicle, and then the air flow inside the hollow layer is driven by the operation of the heat dissipation fan, and the heat inside the hollow layer is dissipated through the heat dissipation port, wherein the filter is used to prevent dust and other debris from entering the interior of the rear door of the engineering vehicle, so as to improve the heat insulation effect of the rear door of the engineering vehicle.

[0004] During the use of the existing split-type engineering vehicle rear door that is easy to maintain, since the engineering vehicle is in use and contains a certain volume of materials, it is subject to bumps during transportation. The materials are likely to press against the rear door of the engineering vehicle, which will not only cause the engineering vehicle to be impacted, but also cause the rear door to deform. In addition, the engineering vehicle needs to be repaired after being transported for a period of time. The rear door is large in size and not easy to disassemble, which increases the difficulty for the staff and needs to be improved. Therefore, the technical personnel in this field provide a split-type engineering vehicle rear door that is easy to maintain to solve the problems raised in the above background technology.
