Description

Technical Field

[0001] This invention belongs to the field of bogie maintenance technology, and particularly relates to a multifunctional bogie lifting frame. Background Technology

[0002] As the core running gear of rail vehicles, the bogie plays a crucial role in supporting the car body, guiding the vehicle along the track, and buffering vibration and impact. In the inspection and maintenance of bogies, the lifting frame is an indispensable piece of specialized equipment, mainly used to achieve the smooth lifting and lowering of the bogie so that technicians can disassemble, clean, assemble, precisely measure, and comprehensively inspect key components such as the frame, wheelsets, and suspension devices.

[0003] However, in actual use, during long-term repeated lifting operations, the track groove on the surface of the traditional bogie lifting frame is prone to misalignment with the fixed track on the ground, which in turn creates gaps. When the bogie is pushed in or moved out along the track, the drive wheels are prone to collision with the track joints, which can easily cause scratches on the surface of the drive rollers, affecting the appearance and corrosion resistance. Therefore, there is an urgent need for a multi-functional bogie lifting frame to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that gaps in traditional bogies during long-term use cause impacts on the surface of the drive rollers, thus affecting their usability. Therefore, this invention proposes a multifunctional bogie lifting frame.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, by setting a compensation device, when the lifting plate moves downward, the lifting frame causes the compensation block to move downward. The track on the ground presses the inclined surface at the bottom of the compensation block, causing the compensation block to move inward. This causes the compensation block to drive the transmission frame to move through the support rod and transmission block, which in turn causes the transmission frame to press the first spring. When the lifting plate moves to the lower position, the rebound force of the first spring causes the compensation block to fit into the track on the ground to compensate for the gap, thus preventing the gap between the track groove on the surface of the lifting plate and the track on the ground from damaging the drive wheel.

[0016] 2. In this invention, by setting an adjustment device, the worm is driven to rotate by a knob, so that the worm drives the rotating rod to rotate through the worm wheel, the rotating rod drives the threaded rod to rotate, the threaded rod drives the threaded seat to move, and the threaded seat drives the first support box to move. Therefore, the distance between the first support box and the second support box is adjusted, thereby meeting the requirements of the bottom drive wheel distance of bogies of different sizes, thus improving the applicability of the device.

[0017] 3. In this invention, by setting up an ejection device, the lifting plate moves downward, causing the lifting plate to drive the top plate to move downward. This causes the top plate to drive the connecting rod to move via the fixed plate. The connecting rod then drives the ejection plate to move via the connecting plate and the slider. This causes the ejection plate to eject the drive wheel between the two support rollers, allowing the drive wheel to move out of the support rollers. This facilitates the ejection of the bogie after maintenance and improves the ease of use of the device. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-4 The present invention provides a technical solution: a multifunctional bogie lifting frame, including a support frame 1, a lifting module 2 installed inside the support frame 1, and further comprising: Lifting plate 3, the bottom of the two lifting plates 3 are respectively connected to the top of the lifting module 2, and two first mounting grooves 11 and two second mounting grooves 9 are respectively opened on one side of the lifting plate 3. A first support box 7 is slidably connected in the first mounting groove 11, and a second support box 10 is installed in the second mounting groove 9. Two support rollers 8 are installed in both the first support box 7 and the second support box 10. Compensation device 4, multiple compensation devices 4 are respectively installed on both sides of the lifting plate 3. The compensation device 4 includes a side groove 404, which is opened on one side of the lifting plate 3. A compensation block 401 is slidably connected in the side groove 404. The gap between the lifting plate 3 and the bottom track is compensated and fitted by the movement of the compensation block 401.

[0022] Furthermore, the compensation device 4 also includes: An internal slot 403 is provided on one side of the compensation block 401; Support rod 406, one side of support rod 406 is connected to one side of the inner wall of built-in groove 403, and transmission blocks 407 are connected to both sides of support rod 406; Mounting bracket 405, one side of mounting bracket 405 is connected to one side of the inner wall of side groove 404.

[0023] Furthermore, the compensation device 4 also includes: The transmission frame 408 has one side attached to and slidably connected to the inner wall of the mounting frame 405, and two fixing grooves are provided inside the transmission frame 408. The transmission groove 410 has two grooves respectively opened on both sides of the inner wall of the transmission frame 408, and the inner wall of the transmission groove 410 is slidably connected to the outer wall of the corresponding transmission block 407.

[0024] Furthermore, the compensation device 4 also includes: The two fixing rods 409 are slidably connected to the inner wall of the corresponding fixing groove, and the two ends of the fixing rods 409 are respectively connected to the two sides of the inner wall of the mounting bracket 405. First spring 411, multiple first springs 411 are sleeved on the corresponding fixed rod 409, and the two ends of the first spring 411 are respectively connected to one side of the inner wall of the mounting frame 405 and one side of the transmission frame 408. Dustproof groove 412 is opened on one side of the inner wall of side groove 404, and dustproof plate 402 is slidably connected to the inner wall of dustproof groove 412. One side of dustproof plate 402 is connected to one side of compensation block 401.

[0025] The specific implementation method is as follows: By setting up a compensation device 4, the lifting module 2 drives the lifting plate 3 to move downward, causing the lifting frame to drive the compensation block 401 to move downward. When one side of the compensation block 401 contacts the track on the ground, the track on the ground presses against the inclined surface at the bottom of the compensation block 401, causing the compensation block 401 to move inward. This causes the compensation block 401 to drive the support rod 406 to move, and the support rod 406 to drive the transmission block 407 to move. The transmission block 407 slides in the transmission groove 410, causing the transmission block 407 to drive the transmission frame 408 to move through the transmission groove 410. This causes the transmission frame 408 to compress the first spring 411. The fixing rod 409 supports the first spring 411 to prevent the first spring 411 from being compressed. When the lifting plate 3 is lowered, the bending during compression affects the rebound effect of the first spring 411. After the lifting plate 3 is lowered into place, the rebound force of the first spring 411 drives the compensation block 401 to fit against the track on the ground to compensate for the gap. This prevents the gap between the track groove on the surface of the lifting plate 3 and the track on the ground from damaging the drive wheel. The lifting plate 3 has multiple support boxes on its top, allowing a single lifting plate 3 to lift two bogies, thereby improving the lifting and maintenance efficiency of the device. The compensation block 401 drives the dustproof plate 402 to slide in the dustproof groove 412, so that the dustproof plate 402 protects the top of the side groove 404, preventing dust from entering the side groove 404 and adhering to the surface of the first spring 411, thus avoiding affecting the movement of the compensation block 401.

[0026] Please see Figures 5-8 An adjustment device 5 is installed inside the lifting plate 3. The adjustment device 5 includes: Support grooves 505, multiple support grooves 505 are respectively opened on both sides of the inner wall of the first mounting groove 11; Support blocks 504, the outer walls of multiple support blocks 504 are slidably connected to the inner walls of corresponding support grooves 505, and one side of support block 504 is connected to one side of the first support box 7.

[0027] Furthermore, the adjustment device 5 also includes: Two movable slots 510 are formed on one side of the inner wall of the corresponding first mounting slot 11, and a through slot 509 is formed between the two movable slots 510. The inner groove 511 is formed inside the lifting plate 3, and the inner groove 511 is connected to the through groove 509. The rotating rod 501 has its outer wall rotatably connected to the inner wall of the through groove 509, and both ends of the rotating rod 501 are connected to threaded rods 503. One end of the threaded rod 503 is rotatably connected to one side of the inner wall of the movable groove 510. The outer wall of the threaded rod 503 is threadedly connected to a threaded seat 502, and one side of the threaded seat 502 is connected to one side of the corresponding first support box 7.

[0028] Furthermore, the adjustment device 5 also includes: The worm 507 has its bottom rotatably connected to the bottom of the inner wall of the inner groove 511, and a knob 506 is connected to the top of the worm 507, with the top of the knob 506 extending out of the inner groove 511. The worm gear 508 has its inner wall connected to the outer wall of the rotating rod 501, and its outer wall meshes with the outer wall of the worm 507.

[0029] The specific implementation method is as follows: By setting an adjustment device 5, rotating the knob 506 causes the knob 506 to drive the worm gear 507 to rotate, which in turn drives the worm wheel 508 to rotate. The worm wheel 508 drives the rotating rod 501 to rotate, which in turn drives the threaded rod 503 to rotate. The threaded rod 503 drives the threaded seat 502 to move, and the threaded seat 502 drives the first support box 7 to move. Therefore, the distance between the first support box 7 and the second support box 10 is adjusted to meet the spacing of the bottom drive wheels of different sizes of bogies, thus improving the applicability of the device. By setting a support block 504 in the support groove 505, the support block 504 supports the first support box 7, improving the stability of the support of the first support box 7. Furthermore, the support block 504 compensates for the distance between the first support box 7 and the first mounting groove 11, preventing the distance between the first support box 7 and the first mounting groove 11 from affecting the bogie pushing operation.

[0030] Please see Figure 9 Both the first support box 7 and the second support box 10 are connected to an ejector device 6, which includes: Connecting slots 609, multiple connecting slots 609 are respectively opened on one side of the first support box 7 and the second support box 10; Side plate 612, one side of multiple side plates 612 is connected to one side of the first support box 7 and the second support box 10 respectively, and a sliding groove 606 is provided on one side of the side plate 612.

[0031] Furthermore, the ejection device 6 also includes: Slider 607, one side of each slider 607 is slidably connected to the inner wall of the corresponding slide groove 606; Connecting rod 604, one end of multiple connecting rods 604 is connected to one side of the corresponding slider 607, and the other side of multiple connecting rods 604 extends out of the first support box 7 and the second support box 10 through connecting groove 609 respectively; Connecting plate 610, the bottom of multiple connecting plates 610 is connected to the top of the corresponding connecting rod 604, the top of the connecting plate 610 is connected to the ejector plate 603, one side of the ejector plate 603 is connected to one side of the slider 607.

[0032] Furthermore, the ejection device 6 also includes: The top of the second spring 611 is connected to the bottom of the corresponding ejector plate 603, and the bottom of the second spring 611 is connected to the bottom of the first support box 7 and the second support box 10 respectively. The fixing plate 602 has one side connected to one end of the connecting rod 604, and two trapezoidal grooves 605 are opened on one side of the fixing plate 602. Trapezoidal strips 608 are slidably connected in the trapezoidal grooves 605, and one side of the multiple trapezoidal strips 608 is connected to one side of the first support box 7 and the second support box 10, respectively. Top plate 601, one side of multiple top plates 601 is connected to one side of the corresponding fixing plate 602.

[0033] The specific implementation method is as follows: By setting the ejector device 6, the lifting plate 3 moves downward, causing the lifting plate 3 to drive the top plate 601 downward. When the top plate 601 contacts the ground, the top plate 601 drives the fixed plate 602 to move. The fixed plate 602 drives the connecting rod 604 to move. The connecting rod 604 drives the connecting plate 610 and the slider 607 to move respectively. Both the connecting plate 610 and the slider 607 drive the ejector plate 603 to move, causing the ejector plate 603 to push out the drive wheel between the two support rollers 8, so that the drive wheel moves out of the support rollers 8, thereby facilitating inspection. The repaired bogie is pushed out, improving the ease of use of the device. The trapezoidal groove 605 on one side of the fixed plate 602 slides on the outer wall of the trapezoidal bar 608, so that the trapezoidal bar 608 supports the fixed plate 602, preventing the connecting rod 604 from deflecting and affecting stability when it moves. When the ejector plate 603 moves upward, it stretches the second spring 611, so that the second spring 611 generates a rebound force. Therefore, when the ejector plate 603 moves upward, the rebound force of the second spring 611 pulls the ejector plate 603 downward, so that the support roller 8 can support the drive wheel.

[0034] Working principle: During use, the bogie to be inspected is transported to the top of the lifting plate 3, so that the bottom drive wheels of the bogie are placed on the support rollers 8 inside the first support box 7 and the second support box 10 for support and positioning. If it is necessary to adapt to bogies with different drive wheel spacings, the knob 506 is turned to drive the worm gear 507 to mesh with the worm wheel 508. The worm wheel 508 drives the rotating rod 501 and the threaded rod 503 to rotate synchronously. The threaded rod 503 drives the threaded seat 502 to slide, and the threaded seat 502 drives the first support box 7 to move. By moving the first support box 7, the spacing between the first support box 7 and the second support box 10 is adjusted to adapt to various specifications of bogies. After the inspection is completed, the lifting module 2 drives the lifting plate 3 to descend, and the compensation blocks 401 at both ends move down synchronously to compensate. After the bottom inclined surface of block 401 contacts the ground track, it is squeezed and contracts inward, which drives the support rod 406 to push the transmission block 407 to slide along the transmission groove 410 of the transmission frame 408. This causes the transmission frame 408 to compress the first spring 411 on the outside of the fixed rod 409. After the lifting plate 3 is fully in place, the first spring 411 rebounds and pushes the compensation block 401 to fit the ground track and fill the track gap. When the lifting plate 3 falls to the point where the top plate 601 contacts the ground, the top plate 601 drives the fixed plate 602 to move upward. The fixed plate 602 drives the connecting rod 604 to move upward. The connecting rod 604 drives the slider 607 to slide along the slide groove 606. The connecting plate 610 pushes the ejector plate 603 upward at the same time, lifting the drive wheel between the support rollers 8 away from the support rollers 8, making it easier to push out the bogie that has been repaired.
