Movable bearing surface type automobile

Abstract

The invention relates to a truck with a movable bearing surface, which can self-load and self-unload by relying on self outfit when transporting large objects. The truck mainly consists of a speed and direction change driving axle for a separated and vertical swing arm suspension, a movable bearing surface of a carriage and a gantry lifting device. The swing arm suspension is arranged at the ends of the two beam axes in the back of the truck frame respectively, the front beam and the back beam fix a left longitudinal beam and a right longitudinal beam together, every swing arm is provided with a wheel, a supporting spring and a vibration absorber; the movable bearing surface of the carriage comprises an upper layer and a lower layer, the upper layer is divided into a left bearing board and a right bearing board of the upper carriage, the two boards are arranged outside the two longitudinal beams and the position is higher than the outer diameter of the wheel, the lower layer is divided into a front bearing board and a back bearing board of the lower carriage, the two boards are arranged inside the two longitudinal beams and the position height can be lower than the radius of the wheel, wherein, the back bearing board must be movable; the gantry lifting device comprises a portal frame that is arranged above the carriage, a longitudinal beam at the top of the portal frame and a hanging hoist that is arranged on the longitudinal beams and can move along the longitudinal beams.

Description

technical field [0001] The invention relates to a truck with a movable load-carrying surface. The movable load-carrying surface is used to make space for heavy objects to be hoisted, and the vehicle is equipped with a hoist, which can rely on its own equipment to realize automatic loading when transporting larger objects. Loading and self-unloading does not require other loading and unloading equipment other than the vehicle, and is suitable for the occasions without lifting equipment or the transportation of non-big batch objects, especially the self-loading and self-unloading of difficult objects that rely on manual handling. Background technique [0002] When a car is transporting large objects that are difficult to load and unload manually, first of all, it needs lifting equipment such as a crane or a loader to cooperate with the object to be loaded onto the vehicle at the beginning of the transportation.

Problems solved by technology

[0002] When a car is transporting large objects that are difficult to load and unload manually, first of all, it needs lifting equipment such as a crane or a loader to cooperate with the object to be loaded onto the vehicle at the beginning of the transportation. Hoisting equipment is required to unload the object from the vehicle, and hoisting equipment is required at the start and end positions of the object transportation, so it is very difficult to load and unload the object in places where there is no special hoisting equipment

[0003] At present, trucks with their own cranes are not simply supported by car tires when lifting heavy objects. They need auxiliary mechanical foot support to prevent the vehicle from tipping over when lifting heavy objects on the side. The vehicle-mounted crane and auxiliary mechanical support feet Greatly increased the car's own quality and manufacturing cost

In addition, the loading height of the truck is higher than the diameter of the wheel, and the load-bearing surface of the object is above the diameter of the wheel. The loading height of the object is relatively high, especially after the large object is loaded on the vehicle, the height of the center of gravity of the vehicle increases. , bringing safety hazards to the driving of the car
