Carriage refitting assisted equipment for logistics freight semitrailer

Abstract

The invention relates to carriage refitting assisted equipment for a logistics freight semitrailer. The equipment comprises a bottom plate, a guiding plate, an expansion bracket, air cylinders, a U-shaped frame, connecting racks, a driving rod, clamping devices and protecting devices, wherein guiding plate is mounted at the upper end of the bottom plate, the expansion bracket is mounted at the rear end of the guiding plate, the upper end of the expansion bracket is connected with the U-shaped frame through the air cylinders, the connecting racks are uniformly mounted at the front end of the U-shaped frame, the driving rod is arranged between the connectors, the clamping devices are mounted in the middles of the front ends of the connecting racks, and the protecting devices are symmetrically arranged on the upper side and the lower side of the front end of each connecting rack. The equipment can solve the problems that the surface of a handrail is unsmooth due to the fact that cooled sparks produced by welding are easily solidified to form bulging blocks during assembling of a carriage fence, workers are scalded easily by uncooled welding points, an existing clamp clamps a single handrail generally and clamps the handrail again after welding, the positions of the to-be-welded handrail and the welded handrail deviate probably and the like.

Description

technical field [0001] The invention relates to the field of compartment modification, in particular to an auxiliary equipment for compartment modification of a logistics freight semi-trailer. Background technique [0002] A semi-trailer is a trailer whose axle is placed behind the center of gravity of the vehicle when the vehicle is evenly loaded, and is equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. The type carriage is mainly used to transport bulk particles or feed, livestock and poultry and other goods. The carriage is made of high-quality steel as the skeleton and welded in strict accordance with industry standards. Practical, safe and reliable; [0003] When assembling the existing barn-type car fence, the longitudinal railings need to be positioned with the help of clamps, and then the two are welded and connected. This method is cumbersome to weld and has the following problems: [0004] 1. The sparks generated by ...

AI Technical Summary

Problems solved by technology

[0003] When assembling the existing barn-type car fence, the longitudinal railings need to be positioned with the help of clamps, and then the two are welded and connected. This method is cumbersome to weld and has the following problems:

[0004] 1. The sparks generated by welding are easy to splash randomly, and they are easy to solidify into raised blocks after cooling, resulting in the surface of the railings being not smooth and not beautiful, and after the personnel weld a single longitudinal railing, the welding point cannot be cooled in time, so that the personnel can not repair the railing again. When the longitudinal railing next to it is welded, the uncooled welding point is easy to burn the staff;

[0005] 2. The existing fixture usually clamps and positions a single longitudinal railing, and personnel need to clamp it again after welding. When re-clamping, the position of the longitudinal railing to be welded and the welded longitudinal railing group may deviate. Circumstances that cause the final welded longitudinal railings to not be on the same level
