[0001] The utility model relates to a transportation protection device, in particular to a transportation protection device for high-speed rail wheels. Background Art

[0002] Train wheels are steel wheels made of steel ingots (billets) through hot rolling processing method and are used in cooperation with railway tracks for train movement. The whole wheel is integrally rolled from a wheel blank. The specific production process is as follows: first, the steel ingot is put into a forging industrial furnace for calcination, then it is put under a press by a robotic arm for preliminary forming of the wheel, and then the preliminarily formed wheel is further processed and formed by a hot rolling mill, and the formed wheel is naturally cooled.

[0003] In the production workshop of train wheels, it is usually necessary to carry steel wheels. The existing tools for transporting steel wheels are not targeted. When transporting steel wheels, there is no special tool to fix the steel wheels.

Specific embodiments

[0030] The present utility model will be described in detail below in conjunction with the accompanying drawings and embodiments:

[0031] The existing high-speed rail wheels include a wheel body 1. A wheel rim 2 is convexly provided on the upper side of the outer surface of the wheel body 1. Circular grooves 3 are provided on both the upper end surface and the lower end surface of the wheel body 1. The wheel hub 4 is coaxially and fixedly provided through the upper circular groove 3 and the lower circular groove 3 of the wheel body 1. The upper wheel hub 4 is flush with the upper end surface of the wheel body 1, and the lower wheel hub 4 protrudes from the lower end surface of the wheel body 1. The fixing method during the handling of high-speed rail wheels in the following embodiments is that multiple high-speed rail wheels are stacked between several threaded rods 7. When the high-speed rail wheels are stacked, the wheel rim 2 of the wheel body 1 is on the top, and the lower wheel hub 4 of the wheel body 1 is placed on the upper wheel hub 4 of the adjacent lower wheel body 1. Since the lower wheel hub 4 protrudes from the lower end surface of the wheel body 1, a gap will be generated when the two wheel bodies 1 are stacked.

[0032] Please refer to Figure 1-10, the transportation protection device for high-speed rail wheels of the present utility model includes a vehicle board 5 and moving wheels 6 provided on the lower end surface of the vehicle board 5. A plurality of threaded rods 7 are arranged on the upper end surface of the vehicle board 5 in the vertical direction. A plurality of high-speed rail wheels to be transported are stacked between the plurality of threaded rods 7. When the high-speed rail wheels are stacked, the wheel rim 2 of the wheel body 1 is on the top, and the hub 4 below the wheel body 1 is placed on the hub 4 above the adjacent wheel body 1 below. Since the hub 4 below protrudes from the lower end surface of the wheel body 1, a gap will be generated when two wheel bodies 1 are stacked. In order to prevent the wheel rim 2 of the wheel body 1 from damaging the external thread of the threaded rod 7, a plurality of T-shaped guard plates 8 are sleeved on each threaded rod 7. The T-shaped guard plate 8 is composed of a first horizontal plate 9, a second horizontal plate 10 and a vertical plate 11. The lower end surface of the first horizontal plate 9 contacts the upper end surface of the corresponding wheel body 1. A through hole 12 is provided on the second horizontal plate 10, and the second horizontal plate 10 is sleeved on the threaded rod 7 through the through hole 12. The vertical plate 11 is located between the corresponding wheel rim 2 and the threaded rod 7, playing a role in protecting the external thread of the threaded rod 7 from being damaged by the wheel rim 2 of the wheel body 1. Then, two pressing plates 13 are placed on the topmost high-speed rail wheels, and the corresponding threaded rods 7 pass through the corresponding pressing plates 13. Then, a locking nut 14 is screwed on each threaded rod 7, so that the locking nut 14 moves downward to press the pressing plate 13, and further the pressing plate 13 presses the topmost high-speed rail wheels to complete the fixation of the high-speed rail wheels.

[0033] During use, first place the first high-speed rail wheel between the plurality of threaded rods 7, and then put the T-shaped guard plates 8 on each threaded rod 7, so that the lower end surface of the first horizontal plate 9 of the T-shaped guard plate 8 contacts the upper end surface of the first high-speed rail wheel, and the vertical plate 11 is located between the wheel rim 2 of the wheel body 1 of the first high-speed rail wheel and the corresponding threaded rod 7 to protect the external thread of the threaded rod 7 from being damaged by the wheel rim 2 of the wheel body 1. Then place the second high-speed rail wheel so that the second high-speed rail wheel is stacked on the upper end surface of the first high-speed rail wheel. Then, put the T-shaped guard plates 8 on each threaded rod 7 again. Place a set number of high-speed rail wheels in sequence, and then press the topmost high-speed rail wheels through the locking nuts 14 and the pressing plates 13 to complete the fixation of the high-speed rail wheels. Then move the vehicle board 5 through the moving wheels 6 to realize the handling work of the high-speed rail wheels.

[0034] In this embodiment, there are four threaded rods 7, and each pressing plate 13 is sleeved with the corresponding two threaded rods 7.

[0035] In this embodiment, the two pressing plates 13 are connected together by two connecting rods 15 arranged above, so that the two pressing plates 13 form a whole, and the fixation of the high-speed rail wheels is more firm.

[0036] In this embodiment, a receiving hole 16 is provided on the upper end surface of the vehicle board 5. When placing the first high-speed rail wheel, the hub 4 below the high-speed rail wheel enters the receiving hole 16 of the vehicle board 5 to increase the stability of the high-speed rail wheels.

[0037] In order to further increase the fixing stability of the high-speed rail wheels, in this embodiment, a central bolt 17 is arranged on the vehicle board 5 in the up-and-down direction through the accommodating hole 16. The bottom end of the central bolt 17 penetrates downward through the hub 4 of each high-speed rail wheel and extends from the accommodating hole 16 to the lower side of the vehicle board 5. A fastening nut 18 is threadedly connected to the bottom end of the central bolt 17. By screwing the fastening nut 18, the fastening nut 18 is made to closely adhere to the lower end face of the vehicle board 5, and the nut of the central bolt 17 is made to press downward on the upper end face of the hub 4 above the uppermost high-speed rail wheel, so as to prevent the high-speed rail wheels from shifting during transportation, so that the corresponding threaded rod 7 bears a high pressure.

[0038] In order to achieve the purpose of fixing the high-speed rail wheels of different diameter sizes during handling, in this embodiment, a first slider 19 is fixedly arranged at the bottom end of each threaded rod 7. The first slider 19 is slidably arranged on the vehicle board 5 in the horizontal connection direction between the central axes of the corresponding two threaded rods 7. A regulating bolt 20 is rotatably connected to the outer side surface of each first slider 19. The regulating bolt 20 is threadedly connected to the vehicle board 5; when transporting the high-speed rail wheels, a set number of high-speed rail wheels are stacked between several threaded rods 7, and then by rotating the regulating bolt 20, the regulating bolt 20 moves inward, and further the regulating bolt 20 drives the corresponding threaded rod 7 to move inward through the first slider 19, so that the outer surface of the threaded rod 7 closely adheres to the wheel rim 2 of the high-speed rail wheel, achieving the purpose of fixing the high-speed rail wheel; of course, a corresponding number of T-shaped guard plates 8 are sleeved on each threaded rod 7 to protect the external thread of the threaded rod 7 from being damaged by the wheel rim 2 of the high-speed rail wheel.

[0039] When adjusting the spacing between each threaded rod 7 through the adjusting bolt 20, it is necessary to make an adaptive change in the connection relationship between the pressing plate 13 and the threaded rod 7, or replace the pressing plate 13 with a different one to achieve the purpose of sleeving the pressing plate 13 with the threaded rod 7 with a changed spacing. To solve this problem, in this embodiment, two sliding holes 21 are symmetrically formed on the upper end surface of the pressing plate 13 along the sliding direction of the first slider 19. A second slider 22 is slidably arranged in each sliding hole 21 along the length direction of the sliding hole 21, and the second slider 22 is sleeved with the corresponding threaded rod 7. During use, after placing a set number of high-speed train wheels between several threaded rods 7, then by rotating the adjusting bolt 20, each threaded rod 7 moves inward to fix the high-speed train wheels. Then, the two second sliders 22 of the pressing plate 13 are sleeved on the corresponding two threaded rods 7, so that the pressing plate 13 presses downward on the topmost high-speed train wheels. The two pressing plates 13 are simultaneously sleeved on the four threaded rods 7 and move downward synchronously to press the topmost high-speed train wheels. Since the second slider 22 can move along the moving direction of the first slider 19 in the sliding hole 21, when the second slider 22 is sleeved with the threaded rod 7, it can be adapted by moving the second slider 22. After the two pressing plates 13 are pressed on the topmost high-speed train wheels, then screw on the locking nut 14 to make the pressing plate 13 press the high-speed train wheels tightly.

[0040] Since there is a gap between each adjacent pair of high-speed train wheels, to increase the stability of the fixation of the high-speed train wheels, in this embodiment, a plug block 23 is slidably arranged on the upper end surface of the first horizontal plate 9 of the T-shaped guard plate 8 along the length direction of the first horizontal plate 9. An inclined surface is formed on the inner side surface of the plug block 23. A side plate 24 is fixedly arranged on the outer side of the upper end surface of the second horizontal plate 10. Two springs 25 are fixedly arranged between the side plate 24 and the plug block 23, and the two springs 25 are located on both sides of the through hole 12 of the second horizontal plate 10. During use, the plug block 23 will automatically be inserted into the gap between two adjacent wheels under the action of the spring 25, so that the inclined surface of the plug block 23 contacts the bottom end of the upper wheel body 1, playing a role in stabilizing the high-speed train wheels. Although when the high-speed train wheels tilt during transportation, the high-speed train wheels will press on the plug block 23, forcing the plug block 23 to move outward, the plug block 23 will still play a stabilizing role to a certain extent. The offset force generated when the high-speed train wheels tilt during transportation mainly comes from the four threaded rods 7 and the central bolt 17, and the plug block 23 only plays an auxiliary role.

[0041] In this embodiment, in order to facilitate the placement of the high-speed rail wheel, the plug block 23 will not be completely padded under the high-speed rail wheel. In this embodiment, the outer side surface of the plug block 23 is rotatably connected to an L-shaped rod 26. The L-shaped rod 26 penetrates through the side plate 24 and the vertical rod portion of the L-shaped rod 26 is located outside the side plate 24. A blocking block 27 is fixedly arranged on the outer side surface of the side plate 24. During use, after placing the first high-speed rail wheel, a T-shaped guard plate 8 is sleeved on each threaded rod 7. Before placing the second high-speed rail wheel, the L-shaped rod 26 is pulled to drive the plug block 23 to slide outward, and then the L-shaped rod 26 is rotated so that the vertical rod portion of the L-shaped rod 26 is located outside the blocking block 27. Then the L-shaped rod 26 is released. The plug block 23 moves inward under the action of the spring 25 and drives the L-shaped rod 26 to move inward. However, the vertical rod portion of the L-shaped rod 26 is blocked by the blocking block 27 and stops moving, so that the plug block 23 stops moving inward. Then the second high-speed rail wheel is placed. After placing the second high-speed rail wheel, the L-shaped rod 26 is rotated to release the plug block 23 into the gap between the first high-speed rail wheel and the second high-speed rail wheel.

[0042] In this embodiment, the L-shaped rod 26 is arranged inside one of the springs 25.

[0043] The working principle of the present utility model: During use, first place the first high-speed rail wheel between several threaded rods 7, so that the hub 4 under the first high-speed rail wheel enters the receiving hole 16 of the vehicle board 5. Then a T-shaped guard plate 8 is sleeved on each threaded rod 7, so that the lower end surface of the first horizontal plate 9 of the T-shaped guard plate 8 contacts the upper end surface of the first high-speed rail wheel, and the vertical plate 11 is located between the wheel rim 2 of the wheel body 1 of the first high-speed rail wheel and the corresponding threaded rod 7 to protect the external thread of the threaded rod 7 from being damaged by the wheel rim 2 of the wheel body 1. Then place the second high-speed rail wheel so that the second high-speed rail wheel is stacked on the upper end surface of the first high-speed rail wheel. Then a T-shaped guard plate 8 is sleeved on each threaded rod 7 again. Place a set number of high-speed rail wheels in sequence. Then, by rotating the adjusting bolt 20, each threaded rod 7 moves inward, and the high-speed rail wheels are clamped by the T-shaped guard plates 8. Then two pressing plates 13 are simultaneously sleeved on the four threaded rods 7 and move downward synchronously to press the topmost high-speed rail wheel. After the two pressing plates 13 are pressed on the topmost high-speed rail wheel, the locking nut 14 is screwed on, and the topmost high-speed rail wheel is pressed tightly by the locking nut 14 and the pressing plate 13 to complete the fixation of the high-speed rail wheel. Then, the vehicle board 5 is moved by the moving wheel 6 to realize the handling work of the high-speed rail wheel.
