Description
Technical Field
[0001] The utility model belongs to the technical field of rail trains, and particularly relates to a train grinding workshop. Background Art
[0002] In recent years, with the rapid development of urban rail transit, the urban traffic congestion problem has been greatly improved. During the whole life cycle of the subway, it is necessary to carry out regular maintenance and overhaul to ensure the normal operation of various components and equipment of the vehicle and achieve the clean operation of the vehicle.
[0003] After disassembling the train, it is overhauled according to the process of cleaning - grinding - painting and spraying - drying;
[0004] Since the train is relatively high, when grinding the train currently, a lift truck is used to lift the staff to grind different positions of the train;
[0005] The existing grinding method has the following deficiencies:
[0006] Since the length of the lift truck is small while the length of the train is long, therefore, the staff needs to continuously move the lift truck to grind different positions in the length direction of the train, which is cumbersome to operate and takes a long time. Content of the Utility Model
[0007] In view of this, the utility model provides a train grinding workshop to solve the problem that in the prior art, the staff needs to continuously move the lift truck to grind different positions in the length direction of the train, which is cumbersome to operate and takes a long time.
[0008] The technical solution adopted by the utility model is as follows:
[0009] A train grinding workshop includes a grinding chamber, in which there is a track adapted to the train, and the track is arranged along the length direction of the grinding chamber; on both sides of the track, there are respectively pedals and lifting devices for lifting the pedals, and the pedals are arranged along the length direction of the grinding workshop.
[0010] In this technical solution, it should be noted that the lifting device can be any one of lifting structures such as cylinder lifting, lead screw lifting, and rack and pinion lifting. The length of the pedal is greater than or equal to the length of a single train car. The pedal is made of steel and has strong load-bearing capacity. In this solution, after the train enters the grinding chamber, its position is between the left and right pedals. The staff can stand on the pedal and use grinding tools to grind the train. And the staff can move on the pedal to grind different positions in the length direction of the train, and also drive the pedal to lift through the set lifting device, which is convenient for the staff to grind different positions in the height direction of the train. That is, this utility model only needs to adjust the height of the pedal through the lifting device to grind different positions of the train, with simple operation and shortened working hours.
[0011] Preferably, the lifting device includes columns and a screw rod. The columns are located on one side of the track. A vertically arranged through groove is provided through the columns. A sliding seat is slidably embedded in the through groove, and one end of the sliding seat extends outside the through groove and is connected to the pedal. The two ends of the screw rod are rotatably connected to the two ends of the through groove, and the screw rod is threadedly connected to the sliding seat. There are two columns, and the two columns are symmetrically arranged with the cross-section passing through the center of the pedal as the symmetry plane.
[0012] In this technical solution, it should be noted that the bottom of the column is fixed to the ground by bolts, and the two ends of the screw rod are rotatably connected to the two ends of the through groove through bearings. In this solution, since the sliding seat is threadedly connected to the screw rod, when the screw rod rotates, it will drive the sliding seat to lift along the axial direction of the screw rod, thereby achieving the purpose of lifting the pedal.
[0013] Preferably, a motor for driving the screw rod to rotate is provided at the top of the column.
[0014] In this technical solution, it should be noted that the output shaft of the motor is fixedly connected to the top of the screw rod, and by controlling the forward or reverse rotation of the motor, the sliding seat can be driven to rise or fall.
[0015] Preferably, a ladder is provided on one side of the column, and the ladder is vertically arranged.
[0016] In this technical solution, it should be noted that the staff can climb the ladder to repair the motor at the top of the column.
[0017] Preferably, dust-proof curtains are provided at both openings of the through groove, and both ends of the dust-proof curtains are fixedly connected to the two ends of the through groove. The side wall of the dust-proof curtain is connected to the sliding seat, and the dust-proof curtain can be telescopic.
[0018] In this technical solution, it should be noted that during train grinding, a large amount of iron filings will be generated, and the iron filings may enter the through groove and accumulate, which is not convenient for the staff to manage. Based on this, in this solution, dust-proof curtains are provided at the openings on both sides of the through groove. The dust-proof curtains can expand and contract adaptively as the sliding seat rises or falls (the function can be achieved as long as the length of the dust-proof curtain is much greater than the length of the through groove). Furthermore, when achieving the dust-proof function, it will not interfere with the sliding seat.
[0019] Preferably, fences are provided at both ends of the pedal and on one side close to the lifting device.
[0020] In this technical solution, it should be noted that the fences provided can prevent the staff from falling off the pedal.
[0021] Preferably, a number of reinforcing ribs are provided on the pedal and are connected to each other in sequence.
[0022] In this technical solution, it should be noted that the reinforcing ribs provided can enhance the rigidity of the pedal.
[0023] Preferably, a lighting lamp is provided in the grinding chamber.
[0024] In this technical solution, it should be noted that the lighting lamp provided facilitates the staff to carry out the grinding work.

[0042] Embodiment
[0043] As Figures 1-4 As shown, an in-train grinding workshop is disclosed in an embodiment of the present utility model, which includes a grinding chamber 10. A track 12 adapted to the train is provided in the grinding chamber 10, and the track 12 is arranged along the length direction of the grinding chamber 10. Pedals 20 and lifting devices for lifting the pedals 20 are respectively provided on both sides of the track 12, and the pedals 20 are arranged along the length direction of the grinding chamber 10. It should be noted that the lifting device may be any one of lifting structures such as cylinder lifting, lead screw lifting, and rack and pinion lifting. The length of the pedal 20 is greater than or equal to the length of a single train car. The pedal 20 is made of steel and has a strong load-bearing capacity. In this solution, after the train enters the grinding chamber 10, its position is between the left and right pedals 20. Workers can stand on the pedals 20 and use grinding tools to grind the train. Moreover, the workers can move on the pedals 20 to grind different positions in the length direction of the train, and the lifting devices provided are used to drive the pedals 20 to lift, facilitating the workers to grind different positions in the height direction of the train. That is, in the present utility model, only by adjusting the height of the pedal 20 through the lifting device, different positions of the train can be ground, with simple operation and shortened working hours.
[0044] As Figures 3-4As shown, in this embodiment, the lifting device includes a vertical column 30 and a screw rod 42. The vertical column 30 is located on one side of the track 12. A vertically arranged through groove 43 is provided through the vertical column 30. A sliding seat 40 is slidably embedded in the through groove 43. One end of the sliding seat 40 extends outside the through groove 43 and is connected to the pedal 20. The two ends of the screw rod 42 are rotatably connected to the two ends of the through groove 43. The screw rod 42 is threadedly connected to the sliding seat 40. There are two vertical columns 30, and the two vertical columns 30 are symmetrically arranged with the cross-section passing through the center of the pedal 20 as the symmetry plane. It should be noted that the bottom of the vertical column 30 is fixed to the ground by bolts, and the two ends of the screw rod 42 are rotatably connected to the two ends of the through groove 43 through bearings. In this solution, since the sliding seat 40 is threadedly connected to the screw rod 42, when the screw rod 42 rotates, it will drive the sliding seat 40 to lift along the axial direction of the screw rod 42, thereby achieving the purpose of lifting the pedal 20.
[0045] As Figures 3-4 shown, in this embodiment, a motor 41 for driving the screw rod 42 to rotate is provided at the top of the vertical column 30. It should be noted that the output shaft of the motor 41 is fixedly connected to the top of the screw rod 42. By controlling the forward or reverse rotation of the motor 41, the sliding seat 40 can be driven to rise or fall.
[0046] As Figure 2 shown, in this embodiment, a ladder 32 is provided on one side of the vertical column 30, and the ladder 32 is vertically arranged. It should be noted that the staff can climb the ladder 32 to repair the motor 41 at the top of the vertical column 30.
[0047] As Figures 3-4 shown, in this embodiment, dust-proof curtains 31 are provided at both openings of the through groove 43, and both ends of the dust-proof curtain 31 are fixedly connected to both ends of the through groove 43. The side wall of the dust-proof curtain 31 is connected to the sliding seat 40, and the dust-proof curtain 31 is telescopic. It should be noted that since a large amount of iron filings will be generated during train grinding, the iron filings may enter the through groove 43 and accumulate, which is not convenient for the staff to clean up. Based on this, in this solution, dust-proof curtains 31 are provided at both side openings of the through groove 43. The dust-proof curtain 31 can telescopically adapt to the rise or fall of the sliding seat 40 (its function can be achieved as long as the length of the dust-proof curtain 31 is much greater than the length of the through groove 43). Therefore, when it achieves the dust-proof function, it will not interfere with the sliding seat 40.
[0048] As Figure 3 shown, in this embodiment, fences 22 are provided at both ends of the pedal 20 and on the side close to the lifting device.
[0049] It should be noted that the fences 22 provided can prevent the staff from falling off the pedal 20.
[0050] AsFigure 2 As shown, in this embodiment, the pedal 20 is provided with a number of reinforcing ribs 21 that are connected to each other in sequence. It should be noted that the rigidity of the pedal 20 can be enhanced by the provided reinforcing ribs 21.
[0051] In this embodiment, a lighting lamp is provided in the grinding chamber 10. It should be noted that the lighting lamp facilitates the staff to carry out the grinding work.
[0052] In this embodiment, lifting doors 11 are respectively provided at both ends of the grinding chamber 10.
[0053] The principle of the present utility model is as follows:
[0054] When the train needs to be ground, the lifting doors 11 are opened, and the train enters the grinding chamber 10 through the track 12. At this time, its position is between the left and right pedals 20. The staff can stand on the pedal 20 and use grinding tools to grind the train, and the staff can move on the pedal 20 to grind different positions in the length direction of the train;
[0055] When it is necessary to grind different positions in the height direction of the train, the motor 41 is started. The motor 41 drives the screw 42 to rotate, thereby driving the sliding seat 40 and the pedal 20 connected to the sliding seat 40 to rise or fall, so as to transport the staff to the designated height of the train for grinding.
[0056] Regarding the circuits, electronic components and modules, they are all prior arts. Those skilled in the art can fully implement them without further elaboration. The content protected by the present utility model does not involve improvements to software and methods either.
[0057] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. For the same or similar parts among the embodiments, reference can be made to each other.
[0058] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model.
