Embodiment Construction
[0049] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention is capable of various changes in different embodiments without departing from the scope of the present invention, and that the description and illustrations therein are illustrative in nature and not limiting. this invention.
[0050] The invention provides a semi-trailer and its frame. The semi-trailer frame is mainly composed of two longitudinal beams and several cross beams. The two longitudinal beams are arranged in parallel with each other. The cross beam is connected between the two longitudinal beams and extends The directions are arranged evenly. In some semi-trailer frames used to transport containers or mechanical equipment, locks are provided on two or three beams for fixing containers or mechanical equipment, and the beams with locks can be called "lock beams".

The invention provides a semitrailer and a semitrailer frame, and the semitrailer frame comprises an outer cross beam, an inner beam, a lifting lock head, a base and a lock pin assembly. The inner beam can stretch out and draw back in the extending direction of the outer cross beam, the lifting lock head moves to a certain set position along with the inner beam, and therefore the horizontal position of the lifting lock head in the width direction of the semitrailer frame can be adjusted. Through cooperation of the base, the lock pin assembly, the outer cross beam and the inner beam, the position locking of the outer cross beam and the inner beam is achieved. Meanwhile, a pin in the lock pin assembly is blocked by the base, the base limits the axial movement of the pin, and the situation that the pin is disengaged is avoided. The semitrailer can be used for transporting containers or mechanical equipment with different widths, so that the practicability of the semitrailer is enhanced, the semitrailer is multipurpose, different types of semitrailers do not need to be selected for the containers or the mechanical equipment with different widths, the number and cost of purchased vehicles of vehicle using units are reduced, and contributions are made to energy conservation and environmental protection.
Description
technical field [0001] The invention relates to the technical field of transportation equipment, in particular to a semi-trailer and its frame. Background technique [0002] A semi-trailer is a vehicle used to transport bulk goods. When transporting containers or mechanical equipment, lifting locks are usually used to fix the semi-trailer. The lifting lock head has the advantages of high strength, convenient operation and good reliability. Normally, the position of the lifting lock is fixed and cannot be adjusted by horizontal movement, which limits the scope of use of the semi-trailer with the lifting lock, and can only be selected according to the size of the container or mechanical equipment. semi-trailer to solve. Contents of the invention [0003] An object of the present invention is to provide a semi-trailer frame, which solves the technical problem in the prior art that the lifting lock head cannot be adjusted by horizontal movement, and can ensure that the lifti...
