The invention discloses supporting equipment used for semitrailer head replacement and having a limiting structure, wherein the supporting equipment comprises a supporting frame body and a motor, a sliding groove is formed in the supporting frame body, a threaded sliding body is connected to the interior of the sliding groove, a supporting base body is fixed to the outer surface of the threaded sliding body, and a threaded rod is connected to the interior of the threaded sliding body; an elastic gasket is connected to the top of the supporting plate, a limiting plate is fixedly connected to the end face of one side of the supporting plate, a limiting hole is formed in the limiting plate, a limiting bolt is connected to the interior of the limiting hole, a transverse gear is connected to the lower portion of the threaded rod, and a vertical gear is connected to the outer surface of the transverse gear; and the motor is located on the outer side of the vertical gear. According to the supporting equipment of the limiting structure, through the arranged motor, the vertical gear can form acting force through rotation of the motor, the situation of manual force application is avoided, automation is improved, and labor intensity is reduced.
Description
technical field [0001] The invention relates to the technical field of semi-trailer support equipment, in particular to a support device with a position-limiting structure for replacing the head of a semi-trailer. Background technique [0002] A semi-trailer is a trailer whose axle is placed behind the vehicle's center of gravity (when the vehicle is evenly loaded) and is equipped with a hitch that transmits horizontal and vertical forces to the tractor. Semi-trailers are generally three-axle semi-trailers, and their types are divided into 11-meter warehouse semi-trailers, 13-meter warehouse semi-trailers, and low-bed semi-trailers. It is a heavy-duty transport vehicle connected to the head of the semi-trailer through the traction pin. When the head is replaced, a supporting device is needed to support the car body. [0003] The existing semi-trailer support equipment generally needs to be hand-cranked to form a support force for the car body, which is not only inefficient ...
