Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wheelset paint removal technology, and particularly relates to a wheelset paint removal room. Background Technology
[0002] Wheelsets are the parts of locomotives and rolling stock that come into contact with the rails, consisting of two wheels securely mounted on the same axle. The function of wheelsets is to ensure the locomotive's movement and steering on the rails, bear all static and dynamic loads from the locomotive and rolling stock, transfer them to the rails, and distribute loads caused by track irregularities to other components of the locomotive and rolling stock. Paint removal from wheelsets requires a separate paint removal area to prevent widespread environmental pollution.
[0003] Paint stripping rooms typically use electric doors to open the entrance or exit. However, conventional electric doors have a lot of mechanical components and the door panels themselves are too heavy, so a higher power motor is needed to drive them up, which results in conventional electric doors in paint stripping rooms being relatively wasteful of energy.
[0004] Therefore, we propose using a wheel-type paint stripping room to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to solve the problem of energy waste caused by conventional electric doors in paint stripping rooms, and to propose a wheeled paint stripping room.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] The wheelset paint stripping room includes a housing. Guide sleeves are symmetrically fixedly connected to the entrance and exit of the housing, and a lifting door is slidably installed between the two. A weight bar is slidably installed on the guide sleeves. A fixed frame is fixedly connected to the upper end of the housing. A fixed pulley is rotatably installed on the upper part of the fixed frame. A sling is fitted onto the fixed pulley. One end of the fixed pulley is fixedly connected to the upper end of the weight bar, and the other end is fixedly connected to the lifting door. A motor is fixedly connected inside the upper part of the fixed frame. A winding wheel is fixedly connected to the rotor of the motor. A pull rope is fixedly connected to the upper end of the lifting door, and the upper end of the pull rope is fixedly connected inside the winding wheel. When the lifting door needs to be raised, the drive motor drives the winding wheel to rotate, which in turn winds up the pull rope, pulling the lifting door upwards. During this process, a weight acts downwards on the end of the suspension cable opposite the lifting door, reducing the load on the motor and temporarily opening the lifting door. The motor's power supply is then disconnected, and the weight of the lifting door pulls the pull rope downwards. The pull rope's reaction force acts on the winding wheel, causing the winding wheel to act on the motor's rotor, thus automatically closing the lifting door. This reduces energy consumption compared to conventional electric doors.
[0008] Preferably, a limiting block is provided on the upper side of the lifting door, and the limiting block is fixedly connected to the fixing frame. The limiting block blocks the upper side of the lifting door to prevent the lifting door from rising excessively.
[0009] Preferably, a reinforcing bracket is fixedly connected between the motor and the housing. The reinforcing bracket increases the stability of the motor.
[0010] Preferably, the guide sleeve includes a sleeve body and a first stop block, the first stop block being fixedly connected to the outside of the housing. The sleeve body facilitates the raising and lowering of the weight bar, and the first stop block facilitates the raising and lowering of the lifting door.
[0011] Preferably, the lifting door includes a door panel and a slide bar, with the slide bar symmetrically and fixedly connected to the side end of the door panel. When the door panel is pulled upward by the pull rope, the door panel causes the slide bar to slide upward along the side of the sleeve, and vice versa, the slide bar slides downward along the side of the sleeve, facilitating the lifting and lowering of the lifting door.
[0012] Preferably, the lifting door further includes a weight, which is fixedly connected to the lower center of the door panel. The weight helps to lower the center of gravity of the lifting door.
[0013] Preferably, the weight bar includes a metal bar and a second stop, the second stop being fixedly connected to the lower part of the metal bar. The second stop, positioned below the sleeve, prevents the metal bar from rising excessively, thus limiting the range of its ascent.
[0014] In summary, the technical effects and advantages of this utility model are as follows:
[0015] 1. When the lifting door needs to be raised, the drive motor drives the winding wheel to rotate, which in turn winds up the pull rope, pulling the lifting door upwards. During this process, a weight acts downwards on the end of the suspension cable opposite the lifting door, reducing the load on the motor and temporarily opening the lifting door. The motor's power supply is then disconnected, and the weight of the lifting door pulls the pull rope downwards. The pull rope's reaction force acts on the winding wheel, causing the winding wheel to act on the motor's rotor, thus automatically closing the lifting door. This reduces energy consumption compared to conventional electric doors.
[0016] 2. When the door panel is pulled upward by the pull rope, the door panel causes the slide bar to slide upward along the side of the sleeve. Conversely, the slide bar slides downward along the side of the sleeve, which facilitates the raising and lowering of the lifting door. Attached Figure Description

[0022] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments.
[0023] Reference Figure 1 The wheel assembly paint stripping room includes a housing 1. Guide sleeves 2 are symmetrically and fixedly connected to the entrance and exit of the housing 1. A lifting door 3 is slidably installed between the two guide sleeves 2. A weight bar 4 is slidably installed on the guide sleeves 2. A fixed frame 5 is fixedly connected to the upper end of the housing 1. A fixed pulley 13 is rotatably installed on the upper part of the fixed frame 5. A sling 11 is fitted on the fixed pulley 13. One end of the fixed pulley 13 is fixedly connected to the upper end of the weight bar 4, and the other end of the fixed pulley 13 is fixedly connected to the lifting door 3. A motor 6 is fixedly connected inside the upper part of the fixed frame 5. A winding wheel 7 is fixedly connected to the rotor of the motor 6. A pull rope 8 is fixedly connected to the upper end of the lifting door 3, and the upper end of the pull rope 8 is fixedly connected inside the winding wheel 7.
[0024] Reference Figure 1 A limiting block 9 is provided on the upper side of the lifting door 3, and the limiting block 9 is fixedly connected to the fixing frame 5. The limiting block 9 is used to block the upper side of the lifting door 3 to prevent the lifting door 3 from rising excessively.
[0025] Reference Figure 1 A reinforcing base 10 is fixedly connected between the motor 6 and the housing 1. The reinforcing base 10 is used to increase the stability of the motor 6.
[0026] Reference Figure 1 and 2 The guide sleeve 2 includes a sleeve body 22 and a first stop block 21, with the first stop block 21 fixedly connected to the outside of the housing 1. The sleeve body 22 guides the weight bar 4 to rise and fall, and the first stop block 21 guides the lifting door 3 to rise and fall.
[0027] Reference Figure 1 , 2The lifting door 3 includes a door panel 31 and a slide bar 33. The slide bar 33 is slidably embedded in the side of the sleeve 22. The suspension cable 11 and the pull rope 8 are both fixedly connected to the upper end of the door panel 31, and the slide bar 33 is symmetrically fixedly connected to the side end of the door panel 31. When the door panel 31 is pulled upward by the pull rope 8, the door panel 31 causes the slide bar 33 to slide upward along the side of the sleeve 22, and vice versa.
[0028] Reference Figure 1 and 3 The lifting door 3 also includes a weight block 32, which is fixedly connected to the lower center of the door panel 31. The weight block 32 is used to concentrate the center of gravity on the lower part of the door panel 31.
[0029] Reference Figure 1 , 2 4. The weight bar 4 includes a metal bar 41 and a second stop 42. The metal bar 41 is slidably installed inside the sleeve 22, and the upper end of the metal bar 41 is fixedly connected to the sling 11.

The second stop 42 is used to stop the metal bar 41 from rising excessively by blocking it on the lower side of the sleeve 22.
[0030] Working principle: When the lifting door 3 needs to be raised, the drive motor 6 drives the winding wheel 7 to rotate. The winding wheel 7 winds up the pull rope 8, which pulls the lifting door 3 upward. During this process, the weight bar 4 acts downward on the end of the lifting cable 11 facing away from the lifting door 3, reducing the burden on the motor 6 and temporarily opening the lifting door 3. The power supply to the motor 6 is then disconnected. The weight of the lifting door 3 pulls the pull rope 8 downward, and the pull rope 8 reacts to the winding wheel 7, causing the winding wheel 7 to act on the rotor of the motor 6, thereby automatically closing the lifting door 3.
