Description

Technical Field

[0001] This utility model belongs to the field of railway engineering technology, specifically a track maintenance device for railway engineering. Background Technology

[0002] Railway engineering is a systematic project involving the planning, design, construction and maintenance of railway lines. It covers the construction of facilities such as tracks, bridges, tunnels and stations, and must take into account safety, durability and transportation efficiency. Track maintenance is the key to ensuring smooth operation of the line. Through regular inspection and targeted maintenance, the life of the tracks can be extended to ensure the high-speed, smooth and safe operation of trains.

[0003] According to a search, patent document CN215482004U discloses a railway engineering track maintenance vehicle, including a base. One side of the upper surface of the base has an equipment slot, and the inner wall of the equipment slot has an insertion slot for connecting equipment. An equipment frame is inserted into the insertion slot. A rotary motor is fixedly connected to the upper surface of the base near the equipment slot, and a first pulley is inserted into the output end of the rotary motor. A shaft for transmitting power is fixedly connected to one side of the equipment frame. This railway engineering track maintenance vehicle, through the design of the base and rail pulleys, allows workers to better grasp and operate the equipment via a push handle at one end of the base. The rail pulleys connect to the rails, making propulsion easier and saving labor. When the equipment is not on the rails, the movable pulleys at the bottom allow for horizontal movement, facilitating the transport and relocation of the equipment.

[0004] The aforementioned comparative document also has the following shortcomings: When the track is being ground, the rail pulleys and cleaning rollers are in contact with the track, making it difficult to control the grinding force of the cleaning rollers, which can easily lead to under-grinding or over-grinding. At the same time, when performing forward grinding (the rotation direction of the cleaning rollers is the same as the forward direction of the equipment), the grinding debris can easily remain on the track, causing wheel and rail scratches under the subsequent run-over of trains, thus aggravating equipment wear. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a track maintenance device for railway engineering, which solves the problems that still exist in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a track maintenance device for railway engineering, comprising a mounting plate, a bracket fixedly connected to the top of the mounting plate, a screw threadedly connected to the bracket, a handwheel coaxially fixedly connected to the top of the screw, a lifting plate rotatably connected to the bottom of the screw, two pairs of fixed rods fixedly connected to the bottom of the lifting plate, a mounting frame fixedly connected to the bottom of the two pairs of fixed rods, a grinding component provided on the mounting frame, a cleaning component provided at the bottom of the mounting plate, two pairs of support blocks and two pairs of support columns fixedly connected to the bottom of the mounting plate respectively, a track contact wheel rotatably connected between each pair of support blocks, and a movable roller provided at the bottom of each support column.

[0007] As a further embodiment of this utility model: the grinding assembly includes a mounting base and a rotating shaft. The mounting base is fixedly connected to the top of the mounting frame, and the rotating shaft is rotatably connected to the mounting frame. A motor is fixedly connected to the top of the mounting base. A pulley is coaxially fixedly connected to the output end of the motor. A grinding wheel is coaxially fixedly connected to the rotating shaft. A pulley is coaxially fixedly connected to one end of the rotating shaft. A belt is sleeved between the pulley and the pulley.

[0008] As a further embodiment of this utility model: the cleaning assembly includes a baffle and a second motor, both of which are fixedly connected to the bottom of the mounting plate. A rotating plate is coaxially fixedly connected to the output end of the second motor, and a pair of cleaning brushes are fixedly connected to the bottom of the rotating plate.

[0009] As a further embodiment of this utility model: a pair of guide rods are fixedly connected to the top of the lifting plate, and the top of each guide rod passes through the bracket and is slidably connected to it.

[0010] As a further embodiment of this utility model: a handrail is fixedly connected to the top of the mounting plate.

[0011] As a further embodiment of this utility model, the mounting plate has an opening.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model includes a track contact wheel, a bracket, a screw, a lifting plate, a fixing rod, a mounting frame, and a grinding assembly. The equipment is placed on a track by a pair of track contact wheels to ensure accurate positioning during operation.

[0016] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0017] like Figures 1-3 As shown, this utility model provides a technical solution: A railway track maintenance device includes a mounting plate 1, a bracket 2 fixedly connected to the top of the mounting plate 1, a screw 3 threadedly connected to the bracket 2, a handwheel coaxially fixedly connected to the top of the screw 3, a lifting plate 4 rotatably connected to the bottom of the screw 3, two pairs of fixed rods 5 fixedly connected to the bottom of the lifting plate 4, a mounting frame 6 fixedly connected to the bottom of the two pairs of fixed rods 5, a grinding component on the mounting frame 6, a cleaning component on the bottom of the mounting plate 1, two pairs of support blocks 7 and two pairs of support columns 8 fixedly connected to the bottom of the mounting plate 1 respectively, a track contact wheel 9 rotatably connected between each pair of support blocks 7, a movable roller at the bottom of each support column 8, a handrail 21 fixedly connected to the top of the mounting plate 1, and an opening on the mounting plate 1. Specifically, the equipment is placed on the track via a pair of track contact wheels 9 to ensure accurate positioning during operation. At this time, the moving rollers at the bottom of the support column 8 are suspended in the air. During grinding, the grinding component and the cleaning component are activated respectively. The screw 3 is driven to rotate on the bracket 2 via the handwheel. The screw 3 drives the lifting plate 4 to descend. The lifting plate 4 drives the mounting frame 6 to descend together via the fixed rod 5, so that the grinding component on the mounting frame 6 contacts the track. The contact force between the grinding component and the track is controlled to avoid over-grinding or under-grinding, thereby improving the quality of the rail surface treatment. The mounting plate 1 is moved by pushing the handle 21. During forward grinding, the cleaning component can sweep off and clean the debris remaining on the track after grinding, preventing subsequent trains from running over and causing wheel and rail scratches and equipment wear, thereby improving the safety of train operation. After grinding is completed, the equipment is lifted down and the moving rollers contact the ground for easy movement. The grinding assembly includes a mounting base 10 and a rotating shaft 11. The mounting base 10 is fixedly connected to the top of the mounting frame 6, and the rotating shaft 11 is rotatably connected to the mounting frame 6. A motor 12 is fixedly connected to the top of the mounting base 10. A pulley 13 is coaxially fixedly connected to the output end of the motor 12. A grinding wheel 14 is coaxially fixedly connected to the rotating shaft 11. A pulley 25 is coaxially fixedly connected to one end of the rotating shaft 11. A belt is sleeved between the pulley 25 and the pulley 13. Specifically, starting motor 12, the output of motor 12 drives pulley 13 to rotate, pulley 13 drives pulley 2 15 to rotate via belt, and pulley 2 15 drives grinding wheel 14 to rotate via shaft 11. The surface of grinding wheel 14 contacts the track, and grinding wheel 14 can grind the track when it rotates. The cleaning assembly includes a baffle 16 and a second motor 17. Both the baffle 16 and the second motor 17 are fixedly connected to the bottom of the mounting plate 1. The output end of the second motor 17 is coaxially fixedly connected to a rotating plate 18. A pair of cleaning brushes 19 are fixedly connected to the bottom of the rotating plate 18. Specifically, when the device is placed on the track, a small gap is left between the bottom of the baffle 16 and the track; when the rotating plate 18 is in position... Figure 2 In the state shown, a pair of cleaning brushes 19 are suspended in the air and do not contact the track. The bottom of the cleaning brushes 19 is slightly lower than the upper surface of the track. The baffle 16 can block the splashing debris and sparks to prevent them from falling onto the cleaned track. The second motor 17 is started. The output end of the second motor 17 drives the pair of cleaning brushes 19 to rotate through the rotating plate 18. When the cleaning brushes 19 sweep across the track, they can sweep the debris off. A pair of guide rods 20 are fixedly connected to the top of the lifting plate 4. The top of each guide rod 20 passes through the bracket 2 and is slidably connected to it. Specifically, the lifting plate 4 drives the guide rod 20 to slide on the bracket 2, and the guide rod 20 can prevent the lifting plate 4 from rotating.

[0018] The working principle of this utility model is as follows: The equipment is placed on a track by a pair of track contact wheels 9 to ensure accurate positioning during operation. During grinding, motor 12 and motor 27 are started respectively. Then, the screw 3 is driven to rotate on the bracket 2 by the handwheel. The screw 3 drives the lifting plate 4 to descend. The lifting plate 4 drives the guide rod 20 to slide on the bracket 2. The lifting plate 4 drives the mounting frame 6 to descend together through the fixing rod 5, so that the grinding wheel 14 on the mounting frame 6 contacts the track. The contact force between the grinding wheel 14 and the track is controlled to avoid over-grinding or under-grinding and improve the quality of track surface treatment. The output end of motor 12 drives pulley 13 to rotate. The pulley 13 drives pulley 25 to rotate through the belt. The pulley 215 drives the grinding wheel 14 to rotate through the rotating shaft 11. When the grinding wheel 14 rotates, it can grind the track. The baffle 16 can block the flying debris and sparks, preventing them from falling onto the cleaned track. The output end of the motor 17 drives a pair of cleaning brushes 19 to rotate through the rotating plate 18. When the cleaning brushes 19 sweep across the track, they can sweep away the debris, preventing subsequent trains from running over them and causing wheel and rail scratches and equipment wear, thus improving the safety of train operation.

[0019] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
