Description

Frame for vertical box and transport vehicle

Technical Field

The application relates to the field of transport vehicles, in particular to a frame for a vertical box and a transport vehicle.

Background

The domestic garbage transfer station is an important link in the current environmental sanitation operation, transfers domestic garbage through a closed container and a large-scale transport vehicle, and improves the economy and the environmental protection of garbage transportation.

At present, the structures of the household garbage transfer station mainly comprise two types of vertical boxing and vertical boxing. In the vertical container loading structure, a 15 t-grade container is mostly used domestically, and the container is vertically placed on a berth and is about 6 meters in height. The household garbage collecting vehicle discharges and compresses the garbage into the container through the door at the top of the container until the whole container is filled. The chinese utility model patent with the granted publication number CN2892742Y and the chinese utility model patent with the granted publication number CN201567027U all describe the vertical domestic garbage transfer station. The household garbage transfer trolley transfers the container to the trolley and then carries away the container.

At present, the container is transferred to the transport vehicle in two ways, one is to transfer the container to the transport vehicle through a traction mechanism. A common mode is that a rotary frame is firstly used, for example, a Chinese utility model with an authorization publication number of CN2682039Y describes a rotary frame of a domestic garbage vertical compression transfer station, a garbage can is converted from a vertical state to a horizontal state, and then is hoisted to a transport vehicle by using a hoisting machine, and the mode needs to arrange an additional device at a boxing position, is immovable, is very inconvenient to use, and has high energy consumption and high operation cost; the other is that a traction device is arranged on a frame of a transport vehicle to directly pull the container onto the transport vehicle, for example, the Chinese utility model with the publication number of CN206456285U describes a transfer vehicle container anti-falling device and a transfer vehicle with the anti-falling device, and the Chinese utility model with the publication number of CN201021173Y discloses a steel wire traction mechanism for loading and unloading the vehicle-mounted container, which can directly transfer the container onto the transport vehicle, the power for flexible transfer is provided by the transport vehicle, but a transfer rope set and a winch are used in the transfer process, or steel wires, because the mass of the container is very large and reaches up to 15t, if the transfer rope set and the steel wires are worn due to long-term use, the risk of breakage exists, the potential safety hazard is very large, and in the process of transportation, the container has a state of pulling and hanging, and is easy to shake in the transfer process, and the wear between the contact surfaces of the container and the frame is severe.
