Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose of the present invention, the following detailed description is given to the embodiments, structures, features and effects according to the present invention with reference to the accompanying drawings and preferred embodiments as follows:

a cross beam, as shown in figures 1 and 2, for mounting a friction wheel comprises a beam body 1 and a positioning pad 2.

The opposite ends of the beam body 1 are provided with convex grooves 101, and the top openings of the convex grooves 101 are positioned on the side surfaces of the beam body 1. The convex groove 101 is used for mounting a friction wheel.

The positioning pad 2 is arranged in the convex groove 101 of the beam body 1, the positioning pad 2 is just arranged at the inner bottom of the convex groove 101, and preferably, the positioning pad 2 is arranged in the beam body 1 through a screw; alternatively, the position pad 2 may be mounted by welding or the like. The top end of the positioning pad 2 is provided with a plurality of arc-shaped grooves 201 for positioning the friction wheel.

The plurality of arc-shaped slots 201 form mounting positions for the mounting wheels, as shown in fig. 3, which facilitate adjustment of the specific positions of the mounting wheels on the arc-shaped slots 201, thereby achieving adjustment of the operating position of the transportation assistance system.

A transportation auxiliary system comprises the beam. Specifically, as shown in fig. 4 and 5, the transportation assistance system further includes a friction wheel, wherein the friction wheel includes a clamping plate 301, at least one pair of locking bolts 302, a first assistance bolt 303, a second assistance bolt 304, a positioning plate 305, a positioning rod 306, a rotating shaft 307 and a rotating wheel 308.

The clamping plates 301 are oppositely arranged on two sides of the beam body 1, and one clamping plate 301 is respectively arranged on the left side and the right side of the beam body 1.

The cylindrical nuts of each pair of the locking bolts 302 are respectively arranged on the arc-shaped grooves 201 of the positioning pads 2 in the beam body 1 and are oppositely arranged, the screws of the locking bolts 302 penetrate through the clamping plate 301, the clamping plate 301 is fixed on the beam body 1 through the nuts of the locking bolts 302, namely the clamping plate 301 is fixed on the beam body 1 through the nuts of the locking bolts 302. Preferably, there are two pairs of locking bolts 302, and the symmetry sets up, and stability is strong.

The first auxiliary bolt 303 is connected with the two oppositely arranged clamping plates 301, and the first auxiliary bolt 303 is positioned above the beam body 1; the second auxiliary bolt 304 is connected to the two oppositely arranged clamping plates 301, and the second auxiliary bolt 304 is located below the beam body 1. The first and second

auxiliary bolts

303 and 304 function as auxiliary coupling members for coupling the girder body 1. Wherein, if the locking bolt 302 is pulled out from the beam body 1, the first auxiliary bolt 303 plays a role of suspending the whole friction wheel on the beam body 1, and plays a role of safety protection. The first auxiliary bolt 303 and the second auxiliary bolt 304 are used together to prevent the clamping plate 301 from being inclined when being fixed on the beam body 1. Preferably, the number of the first auxiliary bolts 303 is two, so that the protection performance is high.

The positioning plate 305 is arranged on the first auxiliary bolt 303, the positioning rod 306 is rotatably arranged on the positioning plate 305, and the bottom end of the positioning rod 306 is abutted against the beam body 1. The design has two functions, namely, the positioning rod 306 can play a positioning role, so that the clamp plate 301 and the beam body 1 are prevented from moving in the horizontal direction; second, the positioning plate 305 can also function as the first auxiliary bolt 303.

The rotating shaft 307 is arranged between the bottom ends of the clamping plates 301, and the rotating wheel 308 is rotatably arranged on the rotating shaft 307. The conveyor belt passes through the rotating wheel to change the direction for use. The outer contour of the rotating wheel 308 is in arc transition from the middle to the two sides, and the conveying belt or the pull rope can still be used when being pulled in a non-positive direction, so that the damage rate of the rotating wheel 308 is reduced.

When in use, the friction wheel is arranged on the beam body 1, and the conveyor belt or the pull rope passes through the rotating wheel 308 for use. When the pull cord is offset by a certain amount, the wheel 308 may move left or right, or the pull cord may make a slight movement on the wheel 308. Once the locking bolt 302 falls off from the beam body 1, the first auxiliary bolt 303 plays a role of protection; when the position of the friction wheel needs to be adjusted, the cylindrical nut of each pair of lock bolts 302 is replaced by a proper arc-shaped groove 201.
