[0041] As Figure 1 shown, the monorail vehicle snow removing device of the embodiment includes a support frame structure A and a brush fixing structure B, and the brush fixing structure B is connected below the support frame structure A.
[0042] As Figure 2 and Figure 4 shown, the support frame structure A includes a main beam plate 1, a guide column 3, a linear bearing 4, a hoop 5, an L-shaped mounting plate 6, a tightening tool 7, and a gas spring 8.

[0044] Preferably, the material of the main beam plate 1 in the embodiment is 5083-H111 aluminum alloy.
[0045] The both ends (specifically, the main beam plate bending portions 12) of the main beam plate 1 are connected with the hoop 5, and the L-shaped mounting plate 6 is connected to the outer end of the hoop 5. The support frame structure A is installed on the crush tube at the front end of the vehicle body through the hoop 5, and the support frame structure A is installed on the opening and closing cover at the front end of the vehicle body through the L-shaped mounting plate 6 to realize the fixing function.

[0047] Preferably, the upper and lower ends of the guide column 3 are respectively provided with the dust cover 2 and the guide column protection sleeve 9, which are used to prevent accumulated water from splashing into the interior during the cleaning process to cause rusting of the internal components.
[0048] In the cleaning process, due to the height fluctuation of the track beam, the linear bearing 4 and the gas spring 8 realize the buffering adjustment function of the monorail vehicle snow removal device of the embodiment. The linear bearing 4 is fixed on the cavity of the main beam plate body for placing the guide column 3, and the guide column 3 reduces the friction during the up-down movement through the linear bearing 4.
[0049] Preferably, the linear bearing 4 will inevitably be subjected to radial impact load from the guide column 3, so a shaft sleeve 13 is welded on the cavity of the main beam plate body for placing the guide column 3, to reduce the impact of the impact vibration on the main beam plate body. More preferably, the overall strength of the main beam plate body is improved by welding the shaft sleeve reinforcing rib plate 15 around the shaft sleeve 13 and welding the main beam plate reinforcing rib plate 14.
[0050] The gas spring 8 is connected to the brush holder 10 by bolts, and the telescopic end of the gas spring 8 is connected to the main beam plate body.
[0051] The side of the main beam plate body is provided downward with a tightening tool 7, and the tightening tool 7 of the embodiment is provided as a long bolt. The tightening tool 7 cooperates with the threaded hole on the brush holder 10 through the bolt thereof, so that the height of the brush 11 can be raised without disassembling the device, avoiding wear and tear of the brush 11 during train travel, and effectively reducing the cost of manpower and material resources.
[0052] As shown in Figure 3 and Figure 5 The brush fixing structure B includes the brush holder 10 and the brush 11, and the brush holder 10 is symmetrically arranged with an included angle of 148-152° (preferably an included angle of 150°) on both sides.

[0053] The brush holder 10 and the gas spring 8 are connected by bolts to realize the connection of the two modules. In the forward direction of the vehicle, the brush 11 is arranged in the shape of an arrow, and when the vehicle is running, the brush 11 will sweep the accumulated snow on the track beam from the middle to both sides, and when the vehicle is raised to a certain speed, the accumulated snow on the track beam will be cleaned to the ground.
[0054] Preferably, in order to meet the ability of the brush support 10 to bear impact in a low temperature environment, a high-strength structural steel Q355B is selected in the embodiment, which has a yield strength of 355 MPa or above and a tensile strength of 490 MPa or above, and the performance requirements meet the working strength.
[0055] Preferably, the inner side tube of the brush support 10, the tightening tool connecting square tube 16, the guide column connecting square tube 17 and the fixed brush connecting square tube 18 are all welded and sealed by using carbon steel plates.
[0056] The manufacturing process of the monorail vehicle snow removing device of the embodiment includes machining, welding, painting, assembly and other processes, and the specific process route is: blanking → beveling → sub-assembly welding → profiling → sub-assembly flaw detection → post-weld machining → painting treatment → assembly. The important manufacturing processes will be described below:
[0057] First, the main beam plate 1 is welded, and the brush support 10 is welded. The steel plates and rectangular tubes used are all removed of surface oxidation film by an angle grinder:
[0058] 1) Welding of the main beam plate 1: In order to reduce the weight of the entire device while meeting the specified load requirements, according to finite element calculation, the bending portion 12 of the main beam plate is a stress concentration area, and the maximum stress is 20.2 MPa. In the embodiment, 5083-H111 aluminum alloy is selected as the material of the main beam plate 1 (the tensile strength of 5083-H111 aluminum alloy is generally between 240-280 MPa, and the yield strength is generally 110-130 MPa, which meets the strength requirements; and the elongation is generally between 10-25%, indicating that it has good plasticity and can deform greatly under stress without breaking).
[0059] 1.1) Welding of the bending portion 12 of the main beam plate: Due to the limitation of the bending process, the gap can only be filled by patch welding. This position is a stress concentration area. After welding, the entire weld is subjected to penetration detection. If there are welding cracks in the weld, the defect needs to be repaired and re-detected until the defect is eliminated to prevent the crack from being impacted and cracking during work, as shown in Figure 6 .
[0060] 1.2) Welding of the shaft sleeve 13 and the reinforcing rib plate: When the snow removing device is working, the guide column 3 reduces the friction during the up-down movement through the linear bearing 4. The linear bearing 4 will inevitably be subjected to radial impact load from the guide column 3. Therefore, the shaft sleeve 13 is welded to reduce the impact of vibration on the main beam plate 1, and the shaft sleeve reinforcing rib plate 15 and the main beam plate reinforcing rib plate 14 are welded to improve the overall strength of the main beam plate, as shown in Figures 7 to 9 .
[0061] 2) The brush support 10 welding: in order to meet the brush support 10 in low temperature environment under the ability to bear impact, the material of the brush support 10 in this embodiment is selected to be high-strength structural steel Q355B, the yield strength of which can reach 355MPa or above, and the tensile strength can reach 490MPa or above, and the performance requirements meet the working strength. As shown in Figures 10 to 11 The brush support 10 is composed of a square tube, which has the functions of fixing the angle of the brush 11, fixing the main beam and the support through the guide column 3, and connecting the tightening tool 7. In order to avoid the splashing rain and snow from entering the square tube and causing the internal rust of the support, carbon steel plates are used to weld the fillet weld at both ends of the square tube. After the welding of the brush support 10 is completed, magnetic powder detection is performed on all the welds, and repair welding is performed at the defect position.
[0062] Secondly, the concentricity of the main beam plate 1 and the brush support 10 is ensured, so that the guide column 3 can smoothly slide in the linear bearing 4 without being stuck. Post-weld machining is required for the main beam plate 1 and the brush support 10, and the machining size is as shown in Figure 12 and Figure 13 The transverse distance of the center is 488±0.3mm, and the longitudinal distance is 106±0.2mm.
[0063] Finally, paint treatment: in order to avoid the monorail snow sweeping device from rusting in a humid environment while ensuring the overall appearance, the surface except the threaded mounting hole is sprayed with primer, intermediate coating and topcoat.
[0064] The above only describes the preferred embodiment of the present application, and does not constitute a limitation on the protection scope of the present application. Any modification, equivalent replacement and improvement made within the spirit and principles of the present application shall be included in the protection scope of the claims of the present application.
