[0040] The utility model will be further described below in conjunction with the accompanying drawings.
[0041] In recent years, with the continuous development and rapid progress of my country's railway technology, rails, as the core components of the railway system, provide load and guidance for trains, while the operating loads they bear are also increasing. Rolling contact fatigue and wear are the main reasons affecting the service life of rails. Among them, common contact fatigue includes rail head cracks, collapse, peeling, fat edges and rail abrasions. Rail wear includes vertical wear, side wear, and wave wear (referred to as wave wear). These damages will increase the vibration and noise of trains during operation, and even threaten the safety of train operation. Therefore, when the damage to the rails reaches a certain limit, or at the beginning of these damages, the rails need to be maintained.
[0042] Rail grinding is one of the most commonly used line maintenance technologies by railway engineering departments around the world. It is a grinding operation that grinds the top and profile of the rails with the help of grinding machinery and grinding tools to reduce rail head wear and eliminate defects. Current grinding tools are usually grinding stones, grinding wheels, etc. Grinding wheels or grinding stones need to be replaced after a period of use. Currently, they are usually installed, disassembled, and transported manually, which has problems such as low replacement efficiency, high labor intensity, and poor installation quality.
[0043] At present, when replacing grinding wheels and grinding stones manually, there are the following problems: 1) Manual replacement of grinding wheels requires at least three operators to work at the same time. It takes 30 minutes to replace a single grinding wheel. However, each grinding vehicle has a large number of grinding wheels or abrasive tools, which results in excessive working time and workload for workers, which is time-consuming and labor-intensive; 2) The working site is limited. In a trenchless working environment such as a station, it is necessary to enter the bottom of the vehicle when replacing the grinding wheel. The bottom of the vehicle is at a low height from the ground and is equipped with various hanging parts, which is prone to collision accidents; 3) When entering the limited space under the vehicle to work, two workers are required to lift a 30-jin grinding wheel, and the other person is required to disassemble and tighten the wheel. The labor intensity is high and there is a safety hazard of being hit: 4) When manually replacing the grinding wheel, the installation process relies on manual experience for alignment, which is prone to failure to achieve the optimal alignment state, safety hazards of loose installation, and problems that affect the operating effect of the equipment.
[0044] In response to the above technical issues, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the embodiment of the utility model provides a rail 40 grinding vehicle maintenance auxiliary device, comprising:
[0045] A frame base 10, on which an insulating roller structure 110 is provided, and the insulating roller structure 110 is arranged on the rail 40;
[0046] A folding lifter 20 is slidably disposed on the frame base 10 along the length direction of the frame base 10;
[0047] The universal tray 30 is disposed on the folding lifter 20 .
[0048] It should be noted that the frame base 10 is installed on the rail 40 through the insulating roller structure 110, and can move on the rail 40 through the insulating roller structure 110; the folding lifter 20 is arranged on the frame base 10, has a lifting function, and can slide on the frame base 10, thereby realizing movement along the width and height directions of the rail 40; by setting the universal tray 30, the angle of the parts placed on the universal tray 30 can be adjusted, thereby realizing the role of assisting workers to inspect and repair the rail 40 grinding vehicle.
[0049] It should be noted that when replacing parts, the rail 40 grinding vehicle maintenance auxiliary device provided in this embodiment can be moved to the position of the vehicle bottom component that needs to be replaced, and the universal tray 30 can be lifted up to the corresponding height (such as the grinding wheel, grindstone) of the part to be removed (such as the grinding wheel, grindstone) by the folding lifter 20. Figure 1 , Figure 2 ), remove the parts to be disassembled and drop them onto the universal tray 30, and then retract the folding lifter 20 (as shown in FIG. Figure 5 , Figure 6 The disassembled parts are transported to the parts collection place through the rail 40 grinding vehicle maintenance auxiliary device provided in this embodiment, and the parts to be installed that need to be replaced are placed on the universal tray 30, and transported to the position where the parts need to be installed, and the universal tray 30 is lifted to the corresponding height by the folding lifter 20, and the angle of the universal tray 30 is adjusted to adjust the angle of the parts to be installed on the universal tray 30, and the installation operation is performed after alignment.
[0050] In some embodiments, Figure 4 , Figure 7 As shown, the frame base 10 includes:
[0051] At least two main beams 120, the inner side of which is provided with a slideway for mounting the folding lifter 20;
[0052] A support beam 130 is provided between the two main beams 120;
[0053] At least two sets of insulating roller structures 110 are disposed on the side of the main beam 120 .
[0054] It should be noted that the two main beams 120 are spaced apart along the length direction of the rail 40. The main beams 120 can be made of profiles, such as rectangular profiles, grooved profiles, angle profiles, etc. The slideway is usually arranged on the inner side of the main beam 120 (i.e., the opposite surfaces of the two main beams 120) and is located in a lower position to reduce the height of the entire device. The slideway can be a slot or groove on the main beam 120, and the slideway extends to the entire length of the main beam 120, or extends to the inner side of the rail 40.
[0055] It should be noted that the support beam 130 can also be made of profiles, such as rectangular profiles, groove profiles, angle profiles, etc. The support beam 130 can be fixedly connected between the two main beams 120, or can be slidably embedded in the slide so that the position of the support beam 130 can be adjusted to prevent the support beam 130 from blocking the movement of the folding lifter 20 on the slide, wherein a plurality of slots can be set in the slide, and the support beam 130 or the folding lifter 20 can be limited when they slide into the slots.
[0056] In some embodiments, the distance between the two sets of insulating roller structures 110 is 1433 mm-1441 mm.
[0057] In some embodiments, the insulating roller structure 110 includes two insulating roller mechanisms 1101 , and the distance between the two insulating roller mechanisms 1101 is 55 mm-65 mm.
[0058] It should be noted that the insulating roller structure 110 can be arranged on the outside of the main beam 120 or on the inside of the main beam 120. By arranging the insulating roller structure 110 on the side of the main beam 120 instead of the bottom of the main beam 120, the height of the entire device can be reduced. Among them, the spacing between the two groups of insulating roller structures 110 is 1433mm-1441mm, which can meet the use requirements of the standard track gauge of 1435mm, and the spacing between the two insulating roller mechanisms 1101 is 55mm-65mm, which can meet the requirements of the bottom operation of the grinding vehicle.
[0059] In some embodiments, the insulating roller mechanism 1101 includes:
[0060] The roller support frame 1101A is arranged on the side of the main beam 120;
[0061] The insulating roller 1101B is disposed on the roller support frame 1101A.
[0062] It should be noted that the two insulating roller mechanisms 1101 are symmetrically arranged on the side of the main beam 120, and the roller support frame 1101A extends obliquely downward from the main beam 120. On the one hand, it can reduce the height of the entire device; on the other hand, it can meet the requirement of an appropriate spacing between the bottom of the main beam 120 and the rail 40. Among them, the insulating roller 1101B uses insulating materials (such as rubber, plastic, etc.) to avoid affecting the track circuit.
[0063] In some embodiments, the frame base 10 further includes a limiting member, which is disposed at both ends of the slideway.
[0064] It should be noted that by providing a limiting member, it can be ensured that the folding lifting structure and the support beam 130 will not slide out of the frame base 10, and the limiting member can also be a limiting groove structure.
[0065] In some embodiments, the folding lifter 20 includes:
[0066] A scissor lift structure 210 is provided on the slideway;
[0067] The adjusting screw 220 is disposed on the scissor lift structure 210 and is used for adjusting the scissor lift structure 210 .
[0068] In some embodiments, the scissor lift structure 210 includes two scissor lift mechanisms 2101 , and the adjusting screw 220 is disposed between the two scissor lift structures 210 .
[0069] It should be noted that, usually two scissor lifts are provided to meet the height requirement for working under the vehicle. Since the scissor lift structure 210 is installed in the slide, and the slide is located at the lower part of the inner side of the main beam 120, that is, the space between the two main beams 120 and the height of the main beam 120 provide partial space for accommodating the scissor lift structure 210. The scissor lift structure 210 is usually made of profiles, and the width (or thickness) of the profiles used in the scissor lift structure 210 is smaller than the thickness of the main beam 120, so that when the scissor lift structure 210 is folded, it can accommodate the scissor lift mechanism 2101 located below and make the adjusting screw 220 just higher than the upper surface of the main beam 120, wherein the adjusting screw 220 can be controlled manually or electrically.
[0070] In some embodiments, the universal tray 30 includes:
[0071] A universal shaft 310, provided on the folding lifter 20;
[0072] The parts tray 320 is disposed on the universal shaft 310 .
[0073] It should be noted that when replacing parts, it is not only necessary to lift the parts to be installed to the corresponding height, but also necessary to adjust the angle of the parts to be installed. The parts to be installed can be freely rotated through the universal joint 310, thereby achieving the adjustment of the angle of the parts to be installed.
[0074] It should be noted that a parts enclosure may be provided on the parts tray 320 to prevent the parts from slipping during transportation and rotation.
[0075] In some embodiments, the folding lifter 20 , the universal tray 30 , and the roller support frame 1101A are made of aluminum alloy.
[0076] It should be noted that aluminum alloy is relatively light, which can reduce the workload of workers and facilitate transportation.
[0077] It should be noted that the frame base 10, the folding lifter 20, and the universal tray 30 provided in the present embodiment are all detachably connected. They can be disassembled for storage when not in use, and assembled again for use when needed. The working process of the device provided in the embodiment of the present application when in use is as follows: 1) Place the base frame with the insulating roller 1101B on the rail 40, and install the lower part of the folding lifter 20 into the slideway; 2) Move the rail 40 grinding vehicle maintenance auxiliary device parallel to the lower part of the grinding wheel (or grindstone) used, and raise the folding lifter 20 to an appropriate distance below the grinding wheel mounting base by adjusting the screw 220; 3) After the personnel disassemble the grinding wheel, the grinding wheel naturally falls off into the parts tray 320 connected to the universal shaft 310, and the folding lifter 20 is adjusted to the retracted position (i.e., the low position) by adjusting the screw 220; 4) The rail 40 carrying the grinding wheel is polished. The grinding wheel maintenance auxiliary device moves to the place where the grinding wheel is collected, takes out the grinding wheel that has been worn to the limit, and replaces the new grinding wheel to the parts tray 320; 5) Use the rail 40 grinding wheel maintenance auxiliary device to move the grinding wheel to be installed to the place where the grinding wheel is disassembled, and raise the folding lifter 20 to a position close to the bottom of the mounting base by adjusting the screw 220, and use the lateral movement function of the folding lifter 20 and the longitudinal movement function of the frame base 10 to adjust the position and align; 6) After alignment, the folding lifter 20 is raised to the part to be installed (i.e., the grinding wheel) in the parts tray 320 by adjusting the screw 220, and the mounting base is tightly fitted, and the universal shaft 310 is used to repeatedly rotate to check and confirm that there is no gap between the grinding wheel and the mounting base, and it is tightly fitted. After confirming that the inspection is correct, the personnel tighten it; 7) After the tightening is completed, the folding lifter 20 is lowered to the retracted position by adjusting the screw 220, and the rail 40 grinding wheel maintenance auxiliary device is removed to complete the replacement.
[0078] In summary, compared with the prior art, the advantages of the embodiments of the present utility model are that, by arranging an insulating roller structure 110 on the frame base 10, movement in the length direction of the rail 40 is achieved; by slidably arranging the folding lifter 20 on the frame base 10 along the length direction of the frame base 10, movement in the width direction and height direction of the rail 40 is achieved; by arranging a universal tray 30, the angle of the parts on the universal tray 30 can be adjusted, thereby achieving the effect of auxiliary maintenance, which can solve the problems of low replacement efficiency, high labor intensity, and poor installation quality that exist in the existing manual installation, disassembly, and transportation of molds, thereby improving maintenance efficiency, reducing labor intensity, and improving installation quality.
