Description

Technical Field

[0001] This invention relates to a wheel disassembly device for monorail vehicles, belonging to the field of bogie maintenance technology. Background Technology

[0002] The bogies of single-axle straddle-type monorail vehicles require frequent maintenance of their running tires. Due to the limited space within the car body underframe, the running tires cannot be directly removed. The bogies must be detached from the car body before disassembly and replacement. Decoupling the bogies is complex and time-consuming, and includes the following steps:

[0003] The vehicle needs to be parked on the working rail, with the guide wheels of the bogie in contact with both ends of the lowering device. The car-mounting fixture is then installed at the driving points on both sides of the vehicle. The vehicle is secured, and the support seat above the lowering device is adjusted to ensure it is firmly in contact with the bogie frame. The hydraulic oil and nitrogen in the auxiliary steering cylinder are then released, first releasing the oil pressure and then the air pressure. The nitrogen is released by pressing the exhaust valve core. The pallet and the side plate of the through passage are removed with a wrench, and the liquid cooling and braking pipeline connections are disconnected. The anti-roll chain is removed, the lateral shock absorber is removed, the connection between the multi-functional bracket and the car body is disconnected, and the traction rod is removed. Only after completing the above steps can the bogie be removed. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a single-rail vehicle wheel disassembly device that can disassemble the running wheels without disassembling the bogie, saving a lot of time, manpower and material resources, and solving the problem that the running wheels cannot be directly disassembled due to the small space inside the bogie embedded in the car body underframe.

[0005] To achieve the above objectives / to solve the above technical problems, the present invention is implemented using the following technical solution:

[0006] A wheel disassembly device for a monorail vehicle includes a support frame, a transmission part for adjusting the position of the support frame, and a connecting mechanism for connecting the transmission part and the support frame.

[0007] The support frame is provided with multiple disassembly parts that match the wheels of the monorail vehicle. Each disassembly part includes a motor, a sleeve for disassembling and assembling fasteners, and a gear assembly for the motor to drive the sleeve to rotate.

[0008] The sleeve is movably connected to the gear assembly, and the sleeve is provided with a locking mechanism for locking the sleeve to the support frame; when the locking mechanism is opened, the sleeve is perpendicular to the support frame.

[0009] The transmission unit includes a transmission rod and two transmission blocks symmetrically arranged on the transmission rod;

[0010] The two transmission blocks are respectively connected to one side of the connecting mechanism, and the other side of the connecting mechanism is connected to the support frame. When the transmission rod rotates, the two transmission blocks can move in opposite directions on the transmission rod and drive the connecting mechanism to extend and retract axially in the wheel.

[0011] Furthermore, the locking mechanism includes a linear electromagnet, an elastic element, and multiple locking holes disposed on the circumferential side of the sleeve; the linear electromagnet is disposed on the support frame and has a built-in power supply, and the elastic element is disposed at the connection between the sleeve and the gear assembly; when the linear electromagnet is not energized, its telescopic end is located in the locking hole.

[0012] Furthermore, the elastic element is a torsion spring.

[0013] Furthermore, the gear assembly includes a first gear and a drive wheel assembly; one side of the first gear is rotatably connected to the support frame, and the other side is hinged to the sleeve; the drive wheel assembly is mounted on the power output end of the motor and meshes with the first gear.

[0014] Furthermore, all of the disassembly parts are located on the same side of the support frame and are distributed at equal angles between adjacent disassembly parts.

[0015] Furthermore, the number of disassembly parts is four, and the included angle between two adjacent disassembly parts is 90 degrees. Without increasing the area of ​​the support frame, the twelve sets of fasteners of the wheel can be quickly removed by simply rotating the wheel three times.

[0016] Furthermore, the connecting mechanism includes a first link and a second link; the first link and the second link are hinged and intersecting; the same side of the first link and the second link are respectively hinged to the two transmission blocks, and the other side of the first link and the second link are respectively hinged to the support frame.

[0017] Furthermore, one end of the transmission rod is provided with a handle, and the transmission rod body is provided with threads of different directions and equal lengths. The two transmission blocks are respectively connected to the threads of different directions. When the handle is rotated, the two transmission blocks can move in opposite directions simultaneously along the transmission rod.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0019] This invention places multiple disassembly parts on the same side of the support frame and uses a locking mechanism to lock the sleeve of the disassembly part onto the support frame, making it easy for the entire support frame to enter between the bogie and the car body. After unlocking, the sleeve is perpendicular to the support frame, and the motor drives the gear assembly to drive the sleeve to disassemble the fastening kit. Ultimately, the running wheels can be disassembled without disassembling the bogie, solving the current problem that the running wheels cannot be directly disassembled due to the small space inside the bogie embedded in the car body underframe.

[0031] Example

[0032] like Figure 1 and Figure 2As shown, a monorail vehicle wheel disassembly device includes a support frame 1, a transmission part 2, and a connecting mechanism 3. Multiple disassembly parts 4 are provided on the left side of the support frame 1, with adjacent disassembly parts 4 having the same angle. Specifically, each disassembly part 4 includes a motor 401, a sleeve 402, and a gear assembly 403. The motor 401 is mounted on the support frame 1. The gear assembly 403 includes a first gear 4031 and a drive wheel set 4032. The right side of the first gear 4031 is rotatably connected to the support frame 1. The drive wheel set 4032 includes a drive wheel and a second gear. The second gear is rotatably connected to the support frame 1 and meshes with the first gear 4031. The drive wheel is mounted on the power transmission line of the motor 401. At the output end, the drive wheel meshes with the second gear; the left end of the sleeve 402 is the contact end with the fastening kit, and the right end is the installation end. The right end of the sleeve 402 is connected to the first gear 4031. The motor 401 drives the gear assembly 403 to drive the sleeve 402 to rotate forward or backward, thereby realizing the installation or removal of the fastening kit of the wheel 6. In this embodiment, in order to efficiently remove the twelve sets of fastening kits on the current wheel 6, the number of disassembly parts 4 is four, and the included angle between two adjacent disassembly parts 4 sleeves 402 is 90 degrees. Without increasing the area of ​​the support frame 1, the twelve sets of fastening kits of the wheel 6 can be quickly removed by simply rotating the wheel 6 three times.

[0033] like Figure 3 As shown, in order to allow the entire support frame 1 to be inserted between the vehicle bogie 7 and the vehicle body, the sleeve 402 is provided with a locking mechanism 5. The locking mechanism 5 includes a linear electromagnet 501, an elastic element 502, and multiple locking holes 503 evenly distributed on the left circumference of the sleeve 402. The telescopic end of the linear electromagnet 501 matches the locking hole 503. The linear electromagnet 501 is installed on the left side of the support frame 1 and has a built-in power supply. The right end of the sleeve 402 is hinged to the left side of the first gear 4031. The elastic element 502 is installed at the connection between the sleeve 402 and the first gear 4031 for... When the sleeve 402 is folded up, the elastic element 502 is a torsion spring. When the sleeve 402 is folded up, the elastic element 502 is in a compressed state. At this time, the linear electromagnet 501 is not energized, the telescopic end of the linear electromagnet 501 is located in the lock hole 503, and the disassembly part 4 is in a locked state. When the linear electromagnet 501 is energized, the telescopic end of the linear electromagnet 501 retracts and exits from the lock hole 503. The sleeve 402 rotates under the action of the elastic element 502. After the sleeve 402 stops rotating, the angle between it and the left side of the support frame 1 is 90 degrees, and the disassembly part 4 is in an unlocked state.

[0034] like Figure 4As shown, the transmission part 2 includes a transmission rod 201 and two transmission blocks 202 symmetrically arranged on the transmission rod 201; a handle 203 is installed at the bottom of the transmission rod 201 for easy hand gripping, for the operator to rotate the transmission rod 201. The transmission rod 201 has threads with opposite directions and equal lengths. The two transmission blocks 202 are respectively matched with the threads with opposite directions and installed on the transmission rod 201. When the transmission rod 201 is rotated through the handle 203, the two transmission blocks 202 move in opposite directions along the transmission rod 201 at the same time.

[0035] like Figure 4 and Figure 5 As shown, the connecting mechanism 3 includes a first link 301 and a second link 302; the first link 301 and the second link 302 are distributed crosswise and hinged at the midpoint. The right sides of the first link 301 and the second link 302 are respectively hinged to two transmission blocks 202, and the left sides of the first link 301 and the second link 302 are hinged to the right side of the support frame 1. When the handle 203 is turned, the two transmission blocks 202 move closer or further away at the same time, so that the first link 301 and the second link 302 push the support frame 1 to the left or pull the support frame 1 to the right, realizing the extension or contraction of the connecting mechanism, and adjusting the distance between the disassembly part 4 on the support frame 1 and the fastening kit of the wheel 6 in the axial direction of the wheel 6.

[0036] Working principle

[0037] like Figure 6 and Figure 7 As shown, when it is necessary to replace the running wheel 8 of a monorail vehicle, first, hold the transmission rod 201 and insert the locked disassembly part 4 and support frame 1 into the space between the bogie 7 and the car body from the bottom of the bogie 7. When the position is appropriate, start the linear electromagnet 501. When the linear electromagnet 501 is energized, the telescopic end retracts and exits from the locking hole 503. The sleeve 402 springs up under the action of the elastic element 502. Turn the handle 203 to drive the transmission block 202 to move and adjust the position of the disassembly part 4 in the axial direction of the wheel 8. Then, turn the wheel 8 to align the four sleeves 402 with the four fastening kits of the running wheel 8. Make a fine adjustment to the position of the disassembly part 4 again. After the sleeves 402 are tightened, start the motor 401 to remove the four fastening kits. Repeat the rotation of the wheel 8 three times to quickly remove the twelve sets of fastening kits of the wheel 8.

[0038] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
