Description

Technical Field

[0001] The utility model relates to the technical field of subway vehicle assembly, in particular to an assembly device for a rotating mechanism of a subway vehicle. Background Art

[0002] A one-piece side guard plate of a subway vehicle is made of flexible material and is widely used. It is installed in the subway gangway to play a role in beautification and ensuring the safety of passengers. The two ends of the side guard plate are respectively wound around the rotating mechanism (left) and the rotating mechanism (right). When the vehicle turns or goes up and down slopes, the two carriages will be misaligned with each other. Under the action of the rotating mechanism, the side guard plate will stretch or curl accordingly. To ensure the normal function of the side guard plate, the torsion of the torsion springs inside the two rotating mechanisms and the height of the drum from the ground after the torsion springs are compressed must be the same. In the prior art, when controlling the torsion of the torsion springs of the rotating mechanism, generally, a torque wrench is used to apply force to the central axis of the torsion spring. Whether the force is perpendicular to the central axis during the force application process, the accuracy and quality of the torque wrench, and whether the over-torque is uniform and without impact all affect the final torsion of the torsion spring. The individual differences in the torsion of the torsion springs in the rotating mechanism assembled by the above scheme cause many problems such as abnormal noises during the rotation mechanism collision during vehicle operation, and the signs are not centered after the side guard plate is reset, and the operation safety is low.

[0003] Therefore, it is necessary to provide a new assembly device for a rotating mechanism of a subway vehicle to solve the above technical problems. Summary of the Utility Model

[0024] The realization, functional characteristics and advantages of the object of the present invention will be further described in conjunction with the embodiments with reference to the accompanying drawings. Specific embodiments

[0025] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. However, the present utility model can be implemented in a variety of different ways defined and covered by the claims.

[0026] The present utility model provides an assembling device for a rotating mechanism of a subway vehicle, aiming to solve the problems of large individual differences in the torsion force of the torsion spring in the rotating mechanism processed by the existing assembling device for the rotating mechanism of the subway vehicle and low operation safety.

[0027] As Figure 1 shown, the assembling device for the rotating mechanism of the subway vehicle includes an operation platform 1, an over-torque mechanism 2 and an anti-reverse mechanism 3. The over-torque mechanism 2 is arranged adjacent to the operation platform 1 in a first direction. The rotating mechanism 7 is arranged on the operation platform 1 in the first direction, and the output end of the over-torque mechanism 2 is connected to the first end of the mandrel 7.1 in the rotating mechanism 7. The over-torque mechanism 2 is used to drive the first end of the mandrel 7.1 in the rotating mechanism 7 to rotate so as to pre-tighten the torsion spring in the rotating mechanism 7 and detect the torsion force of the torsion spring in the rotating mechanism 7. The anti-reverse mechanism 3 is arranged on the operation platform 1, and the anti-reverse mechanism 3 is arranged opposite to the rotating mechanism 7, and the anti-reverse mechanism 3 is used to dock with the second end of the mandrel 7.1 in the rotating mechanism 7 and prevent the mandrel 7.1 in the rotating mechanism 7 from reversing. In actual use, the rotating mechanism 7 is arranged on the operation platform 1 in the first direction, the first end of the mandrel 7.1 in the rotating mechanism 7 is connected to the output end of the over-torque mechanism 2, then the anti-reverse mechanism 3 is docked with the second end of the mandrel 7.1 in the rotating mechanism 7, and then the over-torque mechanism 2 is used to drive the mandrel 7.1 to rotate to perform pre-tightening operation on the rotating mechanism 7. At the same time, the over-torque mechanism 2 can detect the torsion force of the torsion spring in the rotating mechanism 7, so as to reduce the individual differences in the torsion force of the torsion spring in the processed rotating mechanism 7, and the anti-reverse mechanism 3 can prevent the mandrel 7.1 from reversing and avoid the torsion spring from driving the reel to hurt people after storing energy, thereby improving the operation safety.

[0028] Combined with reference to Figure 2, the operation platform 1 includes an installation part 1.1 and a movable part 1.2. The installation part 1.1 is provided with a connected horizontal supporting surface 1.1.1 and a vertical supporting surface 1.1.2. The movable part 1.2 is arranged on the horizontal supporting surface 1.1.1 and is rotationally connected to the installation part 1.1. The rotating mechanism 7 is arranged on the movable part 1.2. The assembling device of the rotating mechanism of the subway vehicle further includes a turning driving part 4 and a locking structure 5. The turning driving part 4 is hinged to the installation part 1.1, and the output end of the turning driving part 4 is hinged to the movable part 1.2. The turning driving part 4 can drive the movable part 1.2 to rotate between the horizontal supporting surface 1.1.1 and the vertical supporting surface 1.1.2. The locking structure 5 includes a rotating seat 5.1 and a locking tongue 5.2. The rotating seat 5.1 is arranged on the vertical supporting surface 1.1.2, and the locking tongue 5.2 is rotatably arranged on the rotating seat 5.1. The locking tongue 5.2 can rotate between a first position and a second position to lock or unlock the movable part 1.2. The movable part 1.2 is hinged at the connection of the horizontal supporting surface 1.1.1 and the vertical supporting surface 1.1.2. The operator connects the two ends of the mandrel 7.1 of the rotating mechanism 7 to the anti-rotation mechanism 3 and the over-torque mechanism 2 respectively, and then starts the over-torque mechanism 2 to perform pre-tightening operation on the torsion spring in the rotating mechanism 7. At the same time, the over-torque mechanism 2 can detect the torque of the torsion spring. After the torque reaches the standard, the rotating mechanism 7 is assembled. Then, the turning driving part 4 drives the movable part 1.2 to rotate to the vertical supporting surface 1.1.2 to simulate the loading state of the rotating mechanism 7. And the operator can rotate the locking tongue 5.2 to the first position, so that the locking tongue 5.2 is arranged on the side of the movable part 1.2 away from the vertical supporting part, so that the movable part 1.2 is limited on the vertical supporting surface 1.1.2 to prevent the movable part 1.2 from malfunctioning, which is convenient for the operator to measure the ground clearance of the drum in the rotating mechanism 7 after the torsion spring is compressed. When the locking tongue 5.2 is rotated to the second position, the locking tongue 5.2 unlocks the movable part 1.2, and the turning driving part 4 drives the movable part 1.2 to rotate to the horizontal supporting surface, so as to facilitate the operator to replace the next rotating mechanism 7 to be processed. Thus, it can not only ensure that the torque of the torsion springs in the rotating mechanisms 7 arranged at both ends of the side guard plate is the same, but also ensure that the ground clearance of the drums in the rotating mechanisms is the same, so as to ensure the normal operation of the side guard plate.

[0029] Refer to in combination Figure 3, the over-twisting mechanism 2 includes an installation platform 2.1, an over-twisting driving member 2.2 and a universal joint 2.3. The installation platform 2.1 is arranged adjacent to the working platform 1. The over-twisting driving member 2.2 is arranged on the installation platform 2.1. The universal joint 2.3 is connected between the output shaft of the over-twisting driving member 2.2 and the first end of the core shaft 7.1 in the rotating mechanism 7. The over-twisting driving member 2.2 can drive the first end of the core shaft 7.1 in the rotating mechanism 7 to rotate through the universal joint 2.3. The over-twisting driving member 2.2 drives the core shaft 7.1 in the rotating mechanism 7 to rotate through the universal joint 2.3 to perform pre-tightening operation on the torsion spring. The over-twisting driving member 2.2 is connected to the core shaft 7.1 in the rotating mechanism 7 by using the universal joint 2.3, so as to overcome the position deviation and axis deviation between the torsion spring and the core shaft 7.1 without affecting the torque, so as to achieve the effect of precise transmission and detection, which is more practical.

[0030] Further, the over-twisting mechanism 2 further includes a speed reducer 2.4, an elastic coupling 2.5 and a torque sensor 2.6 connected in sequence. The speed reducer 2.4 is connected to the output shaft of the over-twisting driving member 2.2. The torque sensor 2.6 is connected to the first end of the core shaft 7.1 in the rotating mechanism 7 through the universal joint 2.3. The torque sensor 2.6 is used to detect the torque of the torsion spring in the rotating mechanism 7. The elastic coupling 2.5 is arranged between the torque sensor 2.6 and the over-twisting driving member 2.2, which can avoid the installation error, that is, the axis deviation, between the speed reducer 2.4 and the torque sensor 2.6, and prevent damage to the precision component such as the torque sensor 2.6, affecting the service life and accuracy.

[0031] See in combination Figure 4, the anti-reverse mechanism 3 includes a driving component 3.1 and a docking component 3.2. The driving component 3.1 is arranged on the installation part 1.1 of the operation platform 1. The docking component 3.2 includes a bearing seat 3.2.1, a one-way bearing 3.2.2 and a docking rotating shaft 3.2.3. An installation cavity 3.2.1.1 is formed at the first end of the bearing seat 3.2.1. The second end of the bearing seat 3.2.1 is connected to the output shaft of the driving component 3.1. The driving component 3.1 can drive the docking component 3.2 to approach or move away from the rotating mechanism 7 through the bearing seat 3.2.1. The docking rotating shaft 3.2.3 is rotatably arranged in the installation cavity 3.2.1.1 through the one-way bearing 3.2.2, and the docking rotating shaft 3.2.3 is used for docking with the second end of the core shaft 7.1 in the rotating mechanism 7. After the operator sets the rotating mechanism 7 on the operation platform 1, the driving component 3.1 drives the docking component 3.2 to approach the rotating mechanism 7 through the bearing seat 3.2.1 until the docking rotating shaft 3.2.3 is docked with the second end of the core shaft 7.1, so that the core shaft 7.1 can rotate relative to the bearing seat 3.2.1 through the docking rotating shaft 3.2.3, and the one-way bearing 3.2.2 can prevent the core shaft 7.1 from reversing. Preferably, a square hole is formed in the docking rotating shaft 3.2.3, and a square head matching the square hole is formed at the second end of the core shaft 7.1. The square head of the core shaft 7.1 is clamped into the square hole of the docking rotating shaft 3.2.3 to complete the docking of the docking rotating shaft 3.2.3 and the core shaft 7.1, thereby realizing the rotational connection between the core shaft 7.1 and the bearing seat 3.2.1.

[0032] Wherein, a first stepped surface 3.2.3.1 and a second stepped surface 3.2.3.2 are sequentially arranged on the outer periphery of the docking rotating shaft 3.2.3 along the direction close to the second end of the bearing seat 3.2.1. The one-way bearing 3.2.2 is sleeved on the first stepped surface 3.2.3.1. The anti-reverse mechanism 3 further includes a thrust bearing 3.2.4, and the thrust bearing 3.2.4 is sleeved on the second stepped surface 3.2.3.2. The thrust bearing 3.2.4 and the one-way bearing 3.2.2 are arranged at intervals. The docking rotating shaft 3.2.3 abuts against the bearing seat 3.2.1 through the thrust bearing 3.2.4. The one-way bearing 3.2.2 and the thrust bearing 3.2.4 are respectively arranged on the first stepped surface 3.2.3.1 and the second stepped surface 3.2.3.2, and there is a gap between the one-way bearing 3.2.2 and the thrust bearing 3.2.4, so that the axial force from the core shaft 7.1 in the rotating mechanism 7 is completely borne by the thrust bearing 3.2.4, ensuring the service life of the one-way bearing 3.2.2, while the torsional force is completely borne by the one-way bearing 3.2.2, and the rated torsional force of the one-way bearing 3.2.2 is greater than [X] times the torsional force of the torsion spring to ensure safety.

[0033] Specifically, the driving component 3.1 includes a fixed seat 3.1.1, a worm 3.1.2, an anti-reverse component 3.1.3, and a worm gear 3.1.4. The fixed seat 3.1.1 is arranged on the installation part 1.1. The worm 3.1.2 is slidably arranged on the fixed seat 3.1.1 along the first direction, and the worm 3.1.2 is coaxially arranged with the mandrel 7.1 in the rotating mechanism 7. The anti-reverse component 3.1.3 is connected to the worm 3.1.2. The worm gear 3.1.4 is rotatably arranged on the fixed seat 3.1.1 and meshes with the worm 3.1.2. The worm gear 3.1.4 rotates to drive the worm 3.1.2 to move along the first direction. The worm 3.1.2 has a double-pitch structure to ensure fast forward and backward. The fixed seat 3.1.1 is in the shape of "⊥". The worm gear 3.1.4 and the worm 3.1.2 are fixed on the fixed seat 3.1.1, and the fixed seat 3.1.1 is provided with a waist-shaped hole to allow the worm gear 3.1.4 and the worm 3.1.2 to move up and down. Rotating the worm gear 3.1.4 drives the worm 3.1.2 to move along the first direction, so that the worm 3.1.2 drives the docking component 3.2 to dock with the second end of the mandrel 7.1. By adjusting the position of the docking structure through the driving component 3.1, different sizes can be adapted, and the structure is simple and the operation is convenient.

[0034] In an embodiment, the anti-reverse mechanism 3 further includes a pin shaft 3.3. The anti-reverse component 3.1.3 is provided with two limiting surfaces 3.1.3.1 arranged back to back. The first end of the bearing seat 3.2.1 forms two spaced connecting plates 3.2.1.2. The anti-reverse component 3.1.3 is arranged between the two connecting plates 3.2.1.2. The two limiting surfaces 3.1.3.1 are respectively abutted against the two connecting plates 3.2.1.2. The anti-reverse component 3.1.3 is connected to the two connecting plates 3.2.1.2 through the pin shaft 3.3. The worm 3.1.2 is connected to the bearing seat 3.2.1 through the anti-reverse component 3.1.3. The two limiting surfaces 3.1.3.1 on the anti-reverse component 3.1.3 cooperate with the connecting plates 3.2.1.2 on the bearing seat 3.2.1 respectively, which is beneficial to improving the transmission stability between the worm 3.1.2 and the bearing seat 3.2.1.

[0035] Refer to in combination Figure 5, the over-twisting mechanism 2 further includes a displacement assembly 2.7. The displacement assembly 2.7 includes a bottom plate 2.7.1, a mounting bracket 2.7.4, a limiting structure 2.7.2, and a indexing pin 2.7.3. The bottom plate 2.7.1 is adjacent to the operation platform 1 along the first direction. The mounting bracket 2.7.4 is slidably disposed on the bottom plate 2.7.1 along a direction perpendicular to the first direction. The mounting platform 2.1 is slidably disposed on the mounting bracket 2.7.4 along the first direction. The limiting structure 2.7.2 includes two limiting blocks 2.7.2.1 oppositely disposed on the bottom plate 2.7.1, and the two limiting blocks 2.7.2.1 are respectively disposed on both sides of the mounting bracket 2.7.4 along a direction perpendicular to the first direction. The limiting block 2.7.2.1 is used to abut against the mounting bracket 2.7.4 to limit the mounting bracket 2.7.4. The indexing pin 2.7.3 is disposed at the bottom of the mounting bracket 2.7.4, and the indexing pin 2.7.3 penetrates through the mounting bracket 2.7.4 and abuts against the bottom plate 2.7.1. Rotating the indexing pin 2.7.3 makes the indexing pin 2.7.3 abut tightly against the bottom plate 2.7.1 to lock the mounting bracket 2.7.4. During actual operation, after the operator sets the rotating mechanism 7 on the operation platform 1 and docks it with the anti-reverse mechanism 3, the operator then pushes the mounting bracket 2.7.4 to slide relative to the bottom plate 2.7.1 until it abuts against the frontmost limiting block 2.7.2.1. At this time, the universal joint 2.3 of the over-twisting mechanism 2 is exactly aligned with the first end of the mandrel 7.1. Connect the universal joint 2.3 to the first end of the mandrel 7.1, and then rotate to tighten the indexing pin 2.7.3 so that the indexing pin 2.7.3 locks the mounting platform 2.1 and the bottom plate 2.7.1, thereby preventing the mounting platform 2.1 from shifting and affecting the over-twisting operation and detection accuracy of the over-twisting mechanism 2. When it is necessary to detect the ground clearance of the drum of the rotating mechanism 7 after pre-tightening, the operator needs to push the mounting bracket 2.7.4 until the mounting bracket 2.7.4 abuts against the rearmost limiting block 2.7.2.1, so that the mounting bracket 2.7.4 is away from the operation platform 1, facilitating the operator to measure the ground clearance of the drum of the rotating mechanism.

[0036] In addition, the assembly equipment of the subway vehicle rotating mechanism further includes a control cabinet 6. The control cabinet 6 is electrically connected to the over-twisting mechanism 2. The control cabinet 6 is used to control the over-twisting mechanism 2 to pre-tighten the rotating mechanism 7, and the control cabinet 6 can display the torque value of the torsion spring in the rotating mechanism 7. The control cabinet 6 is electrically connected to the torque sensor 2.6 in the over-twisting mechanism 2 to receive the torque information detected by the torque sensor 2.6 and display it, so that the operator can intuitively observe the torque value of the torsion spring in the rotating mechanism 7 and ensure that the torque values of the torsion springs in the rotating mechanisms 7 processed each time are the same, so as to ensure that the torque values of the rotating mechanisms 7 at both ends of the side guard plate are consistent, thereby ensuring the normal function of the side guard plate.

[0037] Preferably, the assembling device for the rotating mechanism of the subway vehicle further includes a buffer mechanism 8 and a buffer pad 9. The buffer mechanism 8 includes a plurality of buffer units disposed on the working platform 1. At least two buffer units are disposed at one end of the horizontal supporting surface 1.1.1 away from the hinge joint between the movable part 1.2 and the fixed part, and the two buffer units are spaced apart to cooperate with the supporting of the movable part 1.2; at least two buffer units are disposed at one end of the vertical supporting surface 1.1.2 away from the hinge joint between the movable part 1.2 and the fixed part, and the two buffer units are spaced apart to cooperate with the supporting of the movable part 1.2; the buffer pad 9 is disposed on the vertical supporting surface 1.1.2 and is located between the two buffer units for buffering the movable part 1.2.

Preferably, the buffer pad 9 is a polyurethane shock-absorbing strip.

[0038] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention.
