Description

Semitrailer carriage

Technical Field

The utility model relates to a semitrailer component, in particular to a semitrailer carriage.

Background

A plurality of problems can occur in the manufacturing process of the existing semi-trailer carriage part, for example, in the manufacturing process, parts such as an upright post, a side carriage plate and the like need to be assembled together by hinges, handles and the like at the closing position. After welding, the upright columns, the side carriage plates and the like are disassembled, powder spraying operation is carried out, after the upright columns, the side carriage plates and the like are assembled together after powder spraying in a finished vehicle workshop, and the upright columns, the side carriage plates and the like are warehoused after being inspected to be qualified. The operation process wastes working hours seriously, and prolongs the manufacturing period. Meanwhile, because the accessories such as hinges and handles of each trolley are different in manufacturing and welding, the interchangeability of parts of the same batch of trolleys is poor, and the production efficiency is reduced.

In order to solve the above problems, people are always seeking an ideal technical solution.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art, and provides a semitrailer carriage.

In order to achieve the purpose, the utility model adopts the technical scheme that: a semitrailer carriage comprises a boundary beam, an upright post and a side carriage plate, wherein the upright post is vertically detachably arranged on the boundary beam, a lock rod limiting hole is formed in the boundary beam, a plurality of steel plate upper hinges are arranged on one side of the side carriage plate, a plurality of lower hinge holes are formed in the upright post, steel plate lower hinges are detachably arranged on the lower hinge holes, and the steel plate lower hinges and the steel plate upper hinges are transversely in one-to-one correspondence; the steel plate lower hinge and the steel plate upper hinge are rotationally connected through a pin shaft;

an upper lock rod hole and a lower lock rod hole are respectively formed in the position, corresponding to the lock rod limiting hole, of the side carriage plate, and the upper lock rod hole, the lower lock rod hole and the lock rod limiting hole are vertically and linearly distributed; the side of the side carriage plate is also provided with a side lock rod hole, and a lock rod is detachably arranged on the side carriage plate through the upper lock rod hole, the lower lock rod hole, the lock rod limiting hole and the side lock rod hole.

On the basis, the lower hinge hole is detachably provided with the lower steel plate hinge through the fixing bolt.

Based on the above, the hinge welding is on the steel sheet on one side of side railway carriage or compartment board.

Based on the above, the upright column is perpendicular to the boundary beam.

Compared with the prior art, the semi-trailer carriage has substantial characteristics and progress, and particularly, the position of the locking rod limiting device on the side beam is ensured by accurately punching the side beam. Welding the hinges on the steel plates on the specific positions of the side carriage plates by using a positioning tool; the steel plate lower hinge assembled on the stand column is drilled, the stand column is punched by the stand column punching machine, and the accurate position of the steel plate lower hinge on the stand column is guaranteed. And then, directly performing powder spraying operation on parts such as the upright post, the side carriage plate and the like, assembling the lower hinge of the steel plate and the upright post by using bolts, assembling the upper hinge and the lower hinge of the steel plate together by using hinge pins, and finally installing a lock rod, so that the side carriage plate can be freely opened and closed, and the finished vehicle process is completed. Through the manufacturing, after the upright post, the carriage plate and the like are produced, the powder spraying operation is directly carried out, the vehicle closing process is omitted, and the working hours are saved. Meanwhile, the upright columns, the side carriage plates and the like of the same batch of vehicles can be interchanged, so that the production efficiency is greatly improved, and the production cost is reduced.
