The invention relates to a loading and unloading trolley which belongs to the technical field of object transportation and aims to provide the loading and unloading trolley which is convenient for transportation and unloading, low in cost and capable of improving the working efficiency. The adopted technical scheme is described as follows: a lifting frame is hinged at one end of a rack; the middle part of the lifting frame is hinged with a piston rod of a lift cylinder; the cylinder body of the lift cylinder is hinged at the bottom part of the rack; two side-by-side first rollers are arranged on the lifting frame; tops of the first rollers are above the upper surface of the lifting frame; two parallel guide grooves are arranged below the rack; a plurality of long through holes are arranged in the rack above each guide groove; a second roller is arranged in each long through hole; upper surfaces of two shift forks of a control fork are shaped like waves; the two shift forks are respectively arranged in the two guide grooves; and a control cylinder body of the control fork is fixed below the rack. The loading and unloading trolley disclosed by the invention is used for the transportation of heavyweight objects.
Description
technical field [0001] The loading and unloading trolley of the invention belongs to the technical field of object transportation. Background technique [0002] At present, most of the objects are transported by flatbed trucks. People need to lift the objects on the flatbed truck, push them to the destination, and then lift them down. When the objects are heavy, it will bring inconvenience to the staff and time-consuming strenuous. Moreover, in the process of transportation, sometimes there are abnormal situations such as damage to the flatbed car body, non-rotating wheels, broken shafts, and dropped wheels. The repair of the flatbed car is time-consuming and laborious and inconvenient. Work efficiency increases cost again, causes inconvenience to the staff. Contents of the invention [0003] The invention overcomes the shortcomings of the prior art, and the technical problem to be solved is to provide a loading and unloading trolley which is convenient for transportatio...
