Square cabin

Abstract

The invention provides a square cabin, and relates to the technical field of engineering vehicles. The square cabin comprises a fixed cabin body and a movable cabin body. Guiding rails are arranged on outer surfaces of the left side wall and the right side wall of the fixed cabin body, rolling wheels are arranged on the inner surfaces of the left side wall and the right side wall of the movable cabin body, the movable cabin body is erected on the guiding rails of the fixed cabin body through the rolling wheels, the front end of the fixed cabin body is closed, the back end of the fixed cabin body is opened, the front end of the movable cabin body is opened, and a cabin door is arranged at the back end of the movable cabin body, a support is arranged on the upper edge of the back end of the fixed cabin body, a motor is installed on the support, the support can control the motor to ascend and descend, the output end of the motor is in transmission connection with a gear, a rack is arranged on the inner wall of the top of the movable cabin body and is parallel to the guiding rails, and the gear is engaged with the rack. According to the square cabin, under the powering-on condition or the powering-off condition, normal closing of the movable cabin body can be achieved, the structure is simple, and operation is convenient and fast.

Description

technical field [0001] The invention relates to the technical field of engineering vehicles, in particular to shelters on engineering vehicles. Background technique [0002] In some engineering vehicles with special purposes, some equipment carried in the shelter must be used in the open. In the prior art, the shelter of this type of vehicle is usually composed of a fixed cabin and a movable cabin. The fixed cabin is fixed On the chassis of the car, guide rails are installed on the outer surfaces of the two side walls of the fixed cabin, and rollers corresponding to the guide rails are installed on the inner surfaces of the two side walls of the movable cabin. The movable cabin is erected on the guide rails of the fixed cabin through the rollers. , the movable cabin overlaps with the fixed cabin. When the movable cabin is closed, the movable cabin and the fixed cabin together form a closed cabin body. There are generally two ways to control the opening and closing of the mov...

Problems solved by technology

This kind of shelter is relatively simple in structure and low in cost, but it can be seen from the above that this kind of shelter must rely on manual pushing and pulling of the movable cabin to open or close the movable cabin, and the degree of automation is low. When using in the open air, it is necessary to require the vehicle to stop driving first, and then continue driving after opening the activity cabin, which not only delays driving time, but also consumes manpower

[0004] Second, a driving mechanism is installed on the shelter, and the driving mechanism can drive the movable cabin to slide along the side wall of the fixed cabin when there is electricity. Compared with the above-mentioned method of manually controlling the opening and closing of the movable cabin, this method is more convenient , labor-saving, but the shelter with this structure has a big disadvantage. When the shelter does not provide electricity to the motor or the motor fails temporarily, the driving mechanism will not work, and the driving mechanism is fixedly installed in the shelter. The bars are always in the meshing state and cannot be disengaged, and the mobile cabin cannot be pushed or pulled by hand, so the mobile cabin cannot be opened or closed in this case, and the opening and closing of the mobile cabin is controlled by the driving mechanism, and the mobile cabin must be strictly controlled The sliding stroke prevents the movable cabin from sliding out of the cabin due to too long sliding stroke, which affects safety. At present, the structure of the electric control of the opening and closing of the movable cabin is relatively complicated and the manufacturing cost is high
