[0024] In an exemplary embodiment of the present disclosure, a cable trailer crossing bracket is provided, such as Figure 1 As shown, Figure 1 is a schematic diagram showing a cable trailer crossing bracket structure according to an exemplary embodiment; Figure 2FIG. 1 is a schematic diagram showing a through-hole distribution method according to an exemplary embodiment. Figure 1 and Figure 2 Provide explanation.

[0025] Some specific implementation modes described below are intended to facilitate those skilled in the art to understand the present embodiment, and the present embodiment is not limited to some specific implementation modes described below.

[0026] Reference Figure 1 An exemplary embodiment of the present disclosure provides a cable trailer crossing bracket, the cable trailer crossing bracket comprising:

[0027] The vertical beam 1 includes a fixing plate 12 for clamping the tail platform of the belt conveyor, and a fixing rod 11 fixedly connected to the fixing plate 12 and extending upward. The fixing plates 12 are provided with two pieces and are spaced apart and parallel to each other. The two fixing plates 12 are connected by bolts.

[0028] The cross beam 2 includes a support plate 21 fixed to the top of the fixed rod 11 in a horizontal posture and extending in the direction of the belt conveyor, and baffles 22 fixed to the opposite sides of the support plate 21 and extending upward, the baffles 22 are arranged on both sides of the fixed rod 11, and a through hole 4 is opened on the support plate 21 and penetrates the support plate 21 along the length direction of the vertical beam 1;

[0029] The guide roller group 3 includes a transverse guide roller 32 which is rotatably connected to the beam 2 in a horizontal posture, and a vertical guide roller 31 which is rotatably connected to the two ends of the beam 2 in a vertical posture. The transverse guide rollers 32 are spaced apart along the length direction of the beam 2, the top surface of the baffle 22 is higher than the top edge of the arc-shaped side wall of the transverse guide roller 32, and the vertical guide rollers 31 are arranged on two opposite sides of the end of the beam 2.

[0030] For example, refer to Figure 1 and Figure 2 The fixing rod 11 is in the shape of a long straight rod in a vertical posture. There are two fixing plates 12 and both are in a vertical posture. One fixing plate 12 is fixedly connected to the bottom end of the side wall of the fixing rod 11, and the other fixing plate 12 is flush with the edge of the fixing plate 12 fixed to the bottom end of the side wall of the fixing rod 11, and is spaced apart from the fixing plate 12 fixed to the bottom end of the side wall of the fixing rod 11. The two fixing plates 12 are used to respectively abut against the opposite sides of the tail platform of the belt conveyor, and the two fixing plates 12 are fixed by bolts so that the two fixing plates 12 are clamped on the belt conveyor.

[0031] The support plate 21 is in a horizontal position and is fixed to the top of the fixing rod 11. One end of the support plate 21 is fixedly connected to the top of the fixing rod 11, and the other end of the support plate 21 extends in a direction away from the fixing plate 12. The support plate 21 and the fixing plate 12 are arranged on opposite sides of the fixing rod 11. There are two baffles 22 in an angle steel shape. The two baffles 22 are arranged on opposite sides of the top edge of the support plate 21 and are located on opposite sides of the fixing rod 11. The edges of the angle steel-shaped baffles 22 are flush with the side edges of the top surface of the support plate 21, that is, part of the baffle 22 is in a horizontal position and fixedly connected to the edge of the top surface of the support plate 21, and the other part of the baffle 22 is in a vertical position and extends vertically upward in a direction away from the support plate 21, and part of the top surface of the support plate 21 is exposed between the two baffles 22. The through holes 4 penetrate the support plate 21 in the vertical direction, and the through holes 4 are distributed at intervals from the end of the support plate 21 connected to the fixing rod 11 to the other end of the support plate 21 .

[0032] There are two groups of four vertical guide rollers 31. The rotation axis of the vertical guide rollers 31 is vertically arranged and the top is higher than the top surface of the baffle 22. The two groups of vertical guide rollers 31 are respectively arranged at the two ends of the support plate 21. The two vertical guide rollers 31 of the same group are respectively arranged at the two opposite sides of the support plate 21. The arcuate side walls of some vertical guide rollers 31 are located in the area between the two baffles 22, and the arcuate side walls of some vertical guide rollers 31 are located in the area outside the side walls opposite to the two baffles 22. The spacing between the two vertical guide rollers 31 at the end of the crossbeam 2 away from the vertical beam 1 is smaller than the spacing between the two vertical guide rollers 31 at the other end of the crossbeam 2. The two vertical guide rollers 31 with a larger spacing provide a larger entrance for the cable that is about to enter the support plate 21, reducing the difficulty of placing the cable on the support plate 21. The two vertical guide rollers 31 with a smaller spacing provide a limit for the cable leaving the support plate 21, reducing the amplitude of the lateral displacement of the cable and improving the posture stability of the cable.

[0033] There are three transverse guide rollers 32, and the rotation axes of the transverse guide rollers 32 are horizontally arranged and equidistantly distributed along the length direction of the support plate 21. The two ends of the transverse guide rollers 32 are rotatably connected to the opposite side walls of the two baffles 22, respectively. The bottom edge of the arc-shaped side wall of the transverse guide roller 32 is higher than the support plate 21, and the top edge of the arc-shaped side wall of the transverse guide roller 32 is lower than the top surface of the baffle 22. The three transverse guide rollers 32 are all located between the two groups of vertical guide rollers 31, and the through hole 4 is exposed from one side of the transverse guide roller 32.

[0034] In this embodiment, the vertical beam 1 is fixed to the tail platform of the belt conveyor by a fixing plate 12, so that the bottom end of the vertical beam 1 is fixed to the belt conveyor, and the top end of the vertical beam 1 extends upward away from the belt conveyor. The cable can be carried by the support plate 21 fixed to the top end of the vertical beam 1, and maintains a posture extending along the length direction of the support plate 21 under the limiting action of the baffle 22. The friction between the cable and the cross beam 2 is reduced by the transverse guide roller 32, so that the cable can be more easily dragged, and the friction between the cable and the baffle 22 is reduced by the vertical guide roller 31, thereby reducing the possibility of wear due to excessive friction between the cable and the baffle 22.

[0035] In other embodiments, the fixing rod 11 is hollow, and an I-beam 13 is fixedly connected inside the fixing rod 11, with both ends extending to the two ends of the fixing rod 11 respectively. The two wing plates of the I-beam 13 are fixedly connected to the two opposite inner walls inside the fixing rod 11 respectively. The I-beam 13 inside the hollow fixing rod 11 can improve the bending strength of the fixing rod 11, and at the same time can reduce the dead weight of the vertical beam 1, thereby reducing the load on the two fixing plates 12 fixed on the tail platform of the belt conveyor, and improving the connection stability between the vertical beam 1 and the belt conveyor.

[0036] In an exemplary embodiment of the present disclosure, referring to Figure 1 There are multiple through holes 4 and they are spaced apart along the length direction of the cross beam 2. The spacing between adjacent through holes 4 at one end of the cross beam 2 connecting the vertical beam 1 is smaller than the spacing between adjacent through holes 4 at other positions.

[0037] For example, refer to Figure 1 There are six through holes 4, four of which are in the shape of four sharp corners of a rectangle and are distributed at one end of the support plate 21 connected to the vertical beam 1. The four through holes 4 are spaced apart and are arranged in groups of two on the opposite sides of the support plate 21, and the other two through holes 4 are located in the middle position in the length direction of the support plate 21 and are arranged on the opposite sides of the support plate 21.

[0038] In this embodiment, the cable is laid on the support plate 21 from the end of the support plate 21 connected to the vertical beam 1 and extends toward the end of the support plate 21 away from the vertical beam 1. Therefore, the end of the support plate 21 connected to the vertical beam 1 is more likely to accumulate waste liquid and waste residue from the outer wall of the cable. Providing a larger number of through holes 4 at the end of the support plate 21 connected to the vertical beam 1 can speed up the discharge of waste on the support plate 21.

[0039] In an exemplary embodiment of the present disclosure, referring to Figure 1 and Figure 2The support plate 21 includes a transverse rib 212 covering and extending out of the top end of the fixing rod 11, a vertical rib 213 covering a portion of the side wall of the fixing rod 11 and extending out, and a bearing plate 211 fixedly connected to the transverse rib 212, and the portion of the transverse rib 212 extending out of the fixing rod 11 is fixedly connected to the portion of the vertical rib 213 extending out of the fixing rod 11.

[0040] For example, refer to Figure 1 and Figure 2 The part of the transverse rib 212 extending out of the fixing rod 11 is in a triangular structure, and the part of the vertical rib 213 extending out of the fixing rod 11 is also in a triangular structure. The transverse rib 212 and the vertical rib 213 are integrally formed, and the transverse rib 212 is perpendicular to the vertical rib 213. The boundary between the transverse rib 212 and the vertical rib 213 is located on the side of the fixing rod 11 away from the support plate 21. The side of the transverse rib 212 away from the fixing plate 12 is integrally formed with a connecting plate 2121 in a horizontal posture, and the end of the support plate 21 is fixedly connected to the top surface of the connecting plate 2121, and the end of the support plate 21 is flush with the side wall of the fixing rod 11 away from the fixing plate 12.

[0041] In this embodiment, an obliquely arranged oblique reinforcing rib 5 is fixedly connected between the support plate 21 and the fixed rod 11, and the two ends of the reinforcing rib are respectively fixed to the side wall of the fixed rod 11 away from the fixed plate 12 and the bottom surface of the support plate 21, and the bottom surface of the support plate 21 is fixedly connected with an oblique reinforcing plate 51 fixedly connected to the oblique reinforcing rib 5, and the reinforcing plate is located between the top end of the oblique reinforcing rib 5 and the support plate 21. A horizontal transverse reinforcing rib 6 is fixedly connected between the oblique reinforcing rib 5 and the fixed rod 11, and the two ends of the transverse reinforcing rib 6 are respectively fixed to the side wall of the fixed plate 12 away from the fixed plate 12 and the oblique reinforcing rib 5, and the transverse reinforcing rib 6 is located between the top end and the bottom end of the oblique reinforcing rib 5.
