Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Examples

Referring to fig. 1 and 2, the bearing and limiting mechanism of the telescopic machine in this embodiment includes a bearing shaft 1 mounted on a machine body, a rolling body 2 is sleeved on the bearing shaft 1, a bearing wheel 3 is mounted on the rolling body 2, so that the bearing wheel 3 can rotate relative to the bearing shaft 1, wherein in order to ensure that the position of the rolling body 2 relative to the bearing wheel 3 is fixed, rolling body limiting parts 4 are disposed at two ends of the rolling body 2. In the present embodiment, the rolling elements 2 are two bearings disposed side by side, and the rolling element stoppers 4 are bearing positioning rings.

The bearing and limiting mechanism 100 (a mechanism for short) of the telescopic machine is fixed at the front end of each section of the telescopic machine (except for the first section), and as can be seen from fig. 3, the central line M of the telescopic machine is distributed on the machine bodies at the two sides of each section of the telescopic machine in a mirror symmetry manner, so that the support of the previous section of the telescopic machine 200 is realized. Fig. 4 is a state diagram of the previous compressor section 200 with respect to the current compressor section when it is deployed.

In this embodiment, the side plate 6 of the previous section of the compressor 200 is bent to form the folded edge 5, and the folded edge 5 abuts against the bearing surface 31 of the bearing wheel 3. The outer edge of the bearing wheel 3 protrudes upwards to form a limiting end 32, and the limiting end 32 and the bearing surface 31 cooperate to limit the position of the previous telescopic machine 200.

Specifically, the arc inclined transition between the inner wall 33 of the limit end 32 and the bearing surface 31 forms an arc inclined surface 35, and the bent portion of the side plate 6 abuts against the arc inclined surface 35. Since the main stress surface of the previous section of the compressor 200 is the bending position of the side plate 6, that is, the arc inclined surface 35 is the bearing action point, the bearing capacity of the bearing wheel 3 is enhanced by enhancing the structural strength of the bearing wheel 3 at the arc inclined surface 35. The structural strength of the bearing wheel 3 in the embodiment is strongest at the arc inclined surface 35, so that the bearing wheel 3 can bear heavier force.

In this embodiment, in order to facilitate the placement of the hem 5 and the side plate 6 on the previous section of the telescopic machine 200, the inner wall 33 of the limiting end 32 is an inclined surface, and the inclined surface and the bearing surface 31 form an obtuse angle. Specifically, in the present embodiment, the angle between the inclined surface and the bearing surface is defined to be 110 ° to 120 °, and preferably 115 °.

In this embodiment, the bending angle of the folded edge 5 is 90 degrees, but there is a certain angle error after the forming, in order to ensure that unnecessary up-and-down bouncing occurs in the extending section of the previous telescopic machine 200 at a certain time, a slope 34 is arranged on one side of the bearing wheel 3 away from the limit end 32, and one end of the slope 34 is connected with the bearing surface 31. The slope is used for offsetting the influence caused by the error of the angle of the folded edge, and the protruding section is guaranteed to be firmly stressed and not to unnecessarily bounce up and down. In this embodiment, the spacing end 32 and the bearing surface 31 have certain height difference and arc slope transition, so that effective spacing is achieved, and the side plate of the body of the trailer cannot be dragged by the spacing edge during telescopic movement, which affects attractiveness.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered in the protection scope of the present invention.
