Description
Technical Field
The utility model relates to a semitrailer equipment technical field, specific theory especially relates to a semitrailer landing leg winding and unwinding devices.
Background
A semitrailer is a trailer whose axle is positioned behind the center of gravity of the vehicle (when the vehicle is evenly loaded) and which is equipped with a coupling device that transmits horizontal and vertical forces to the tractor. Semitrailers are generally three-axle semitrailers, and the types of semitrailers are divided into eleven-meter-bin-column semitrailers, thirteen-meter-bin semitrailers, low-bed semitrailers and the like. Is a heavy transport vehicle connected with a semitrailer head through a towing pin.
Due to the characteristics of high efficiency and convenience, the semitrailer plays an important role in the transportation process in a field. When the tractor head and the semitrailer are separated, the traction frame of the traction type semitrailer needs to be supported by means of the supporting legs, so that the whole semitrailer forms three-point support, and the traction type semitrailer and the traction head can still be kept stable in a separated mode. The manual mechanical type landing leg of commonly used belongs to external installation, and the manual operation crank can realize the flexible of landing leg, and this form landing leg is used extensively, the bearing capacity is big, but its shortcoming is big to the installation space requirement, can not satisfy the requirement of ultralow semitrailer traction frame to the space, bumps easily at the in-process of traveling, causes the damage of landing leg, influences the life of landing leg, improves use cost.
