Description

Technical Field

[0001] The present invention relates to the field of brakes, in particular to a disassembly mechanism and a lifting vehicle. Background Art

[0002] Currently, there are three main methods for brake disassembly: the first is to use traditional hand tools such as wrenches and hydraulic jacks, which rely on manual operation; the second is to use electric wrenches or servo-driven gearboxes to achieve rotational disassembly; and the third is to use threaded rotary fixtures, which clamp the brake with a chuck or fixture and combine it with a threaded rotation mechanism for disassembly. However, these existing methods have many problems. For example, they can only achieve horizontal movement by lifting, not direct rotation, and often require the removal of obstacles before complete disassembly. In complex situations such as narrow circumferential space around the brake and extreme friction between the bottom surface and the concrete floor, traditional tools are poorly adaptable and easily cause equipment deviation, making it difficult to meet the needs of efficient disassembly. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is that the existing brake disassembly methods mainly include manual tools, electric wrenches / servo-driven gearboxes and threaded rotary tooling fixtures. However, they generally can only be lifted and moved horizontally but cannot be rotated directly. Obstacles need to be removed first, and they have poor adaptability and are prone to displacement in complex situations such as narrow space and high friction.

[0004] The above technical problem is solved by the following technical solution: The present invention proposes a disassembly mechanism, which includes:

[0005] The rotating sleeve includes four groups of arc plates, one side of the arc plate is provided with a groove, the other side of the arc plate is fixedly connected to an adjustment block, the top of the adjustment block is fixedly connected to a clamping plate, the inner side of the clamping plate is provided with a slot, and the four groups of arc plates are connected end to end in sequence through a connecting plate;

[0006] A support plate, the support plate comprising two sets of side plates, a mounting hole being provided on a side of the side plate away from the rotating sleeve, and the two sets of side plates being assembled by a connecting plate;

[0007] The bottom plate includes two sets of panels, one side of the panels close to the support plate is adapted to be mounted with a jack, and the two sets of panels are assembled through a connecting plate;

[0008] The rotating sleeve is rotatably connected to the top of the support plate, and the output end of the jack is locked into the mounting hole. By fitting the rotating sleeve onto the outside of the brake, with the locking slot facing the brake handle, the position of the clamping plate can be adjusted by rotating the adjustment block, and the brake handle can be fixed in place through the locking slot. Activating the jack pushes the support plate upward, simultaneously raising the rotating sleeve and completing the brake removal. Finally, by grasping the air duct, the brake is rotated 90 degrees to ensure smooth brake removal.

[0009] In a preferred embodiment of the disassembly mechanism of the present invention, the adjustment block includes a bottom block fixedly connected to the side of the arc plate where the groove is not formed, a top block slidably connected to the bottom end of the bottom block, and an adjustment bolt disposed inside the bottom block;

[0010] The position of the top block at the top of the bottom block is adjusted by rotating the adjusting bolt. The sliding contact surface between the bottom block and the top block is an inclined surface, and the inclined surface is inclined downward from the adjusting bolt toward the clamping plate. Rotating the adjusting bolt can drive the top block to move at the top of the bottom block. When the brake handle needs to be fixed, the adjusting bolt is rotated forward, thereby driving the clamping plate from the axis of the rotating sleeve toward the outer diameter of the rotating sleeve, thereby gradually achieving the clamping of the clamping plate with the inner wall of the handle. Furthermore, because the sliding contact surface between the bottom block and the top block is an inclined surface, the top block gradually deflects upward as it slides toward the outer diameter of the rotating sleeve, ensuring stability and firmness after the brake is engaged.

[0011] In a preferred embodiment of the disassembly mechanism of the present invention, the clamping slot includes a circular hole and a U-shaped groove. The diameter of the circular hole is larger than the opening diameter of the U-shaped groove, and the circular hole is closer to the connection end between the clamping plate and the adjustment block relative to the U-shaped groove. During the initial installation of the rotating sleeve, the circular hole ensures that the clamping plate can be located inside the brake handle. When the adjustment block is controlled to drive the clamping plate to tighten the brake, the clamping plate slides toward the outer diameter of the rotating sleeve and deflects upward, thereby clamping the U-shaped groove to the inside of the brake handle, thereby completing the fixation of the brake.

[0012] Furthermore, since the diameter of the circular hole is larger than the opening diameter of the U-shaped groove, it can be ensured that after installation is completed, the clamping plate cannot be separated from the handle of the brake at all, thereby improving the fastening performance.

[0013] Moreover, the fastening method of moving the axis of the rotating sleeve toward the outer diameter of the rotating sleeve and offsetting upward can not only improve the fastening, but also increase the distance between the brake and the support plate as much as possible after the fastening is completed, thereby ensuring the smoothness of subsequent work and reducing the risk of friction caused by the brake.

[0014] In a preferred embodiment of the disassembly mechanism of the present invention, an arc groove is formed on the side of the side plate adjacent to the rotating sleeve, a ball is disposed within the arc groove, the groove fits against the top of the ball, and the rotating sleeve rotates by engaging the ball through the groove. By fitting the groove at the bottom of the arc plate over the top of the ball, after the brake is raised, the brake's air duct can be gripped and rotated, while the ball adaptively rolls within the arc groove, easily completing a 90-degree rotation of the brake. This ensures that contact and friction with obstacles are avoided during the final removal of the brake, greatly improving overall disassembly efficiency.

[0015] In a preferred embodiment of the disassembly mechanism of the present invention, a limit block is screwed onto the side of the side plate proximate the rotating sleeve, and a limit bolt is threadedly connected to the inner side of the limit block. The position of the limit bolt is adjusted by rotating it. When the rotating sleeve is mounted on the top of the support plate, the limit bolt is rotated until it contacts the side wall of the arc plate, thereby limiting the position of the rotating sleeve, ensuring that the rotating sleeve does not deviate during rotation, and ensuring that friction caused by deviation is avoided during final brake removal.

[0016] In a preferred embodiment of the disassembly mechanism of the present invention, a guide wheel is mounted on the side of the panel away from the support plate, and a first fixing plate and a second fixing plate are fixedly connected to the opposite sides of the panel. Positioning the guide wheel on the guide block of the guide frame improves the stability of the base plate's movement. The first fixing plate is connected to the threaded block, and the second fixing plate is connected to the auxiliary wheel.

[0017] The present invention also provides a lifting vehicle, comprising the disassembly mechanism, and further comprising:

[0018] A vehicle body, wherein a slide rail is provided on the top of the platform of the vehicle body, and a slider is provided on the top of the slide rail;

[0019] A guide frame, the top of which is fixedly connected to a guide block, has a guide slot formed on one side, and is fixedly connected to the top of the slider. After the disassembly mechanism completes the lifting of the brake and rotates the brake 90 degrees, the driving member of the guide frame can drive the bottom plate to move and gradually position it above the vehicle body, thereby completing the disassembly of the brake.

[0020] The operator pushes the guide frame to enable the slider at the bottom end of the guide frame to slide on the slide rail.

[0021] In a preferred embodiment of the lift truck of the present invention, side bars are pivotally connected to both sides of the truck body, and support bars are provided at one end of each side bar. When the vehicle is in operation, the side bars are rotated to extend, and the support bars enhance the overall stability of the vehicle, ensuring smooth removal of the entire brake.

[0022] In a preferred embodiment of the lift truck of the present invention, a drive member is disposed on the other side of the guide frame where the guide slot is located. The drive member comprises a motor mounted on the outside of the guide frame, a screw fixedly connected to the output end of the motor, and a threaded block disposed on the outside of the screw, with one side of the threaded block abutting against the guide frame. Activating the motor drives the screw, which in turn drives the threaded block to adjust its position, thereby adjusting the position of a base plate connected to the threaded block.

[0023] In a preferred embodiment of the lift truck of the present invention, an auxiliary wheel is disposed within the guide slot, with a screw fixedly connected to one side of the auxiliary wheel. By inserting the screw into the mounting hole of the second fixing plate and securing it with a nut, the auxiliary wheel ensures smooth movement of the base plate as it moves along the guide frame.

[0024] The beneficial effects of the present invention include: efficient clamping and position-limiting fixation of the brake is achieved through the clamping plate and slots of the rotating sleeve, allowing removal to be completed in conjunction with the lifting action of the jack. The unique structure of the rotating sleeve and the arc groove and spherical design of the support plate enable flexible rotation of the brake, avoiding friction and interference from obstacles during the removal process. Furthermore, the design of the lift truck further improves removal efficiency and operational convenience. The vehicle's slide rails, sliders, and the guide frame's drive components and auxiliary wheels enable smooth movement and position adjustment of the brake, improving the overall stability and smoothness of the removal process.

[0042] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0043] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0044] Reference Figures 1 to 12 、 Figure 16 , this embodiment provides a disassembly mechanism, which includes,

[0045] The rotating sleeve 1 includes four sets of arc plates 11. A groove 12 is provided on one side of the arc plate 11. An adjustment block 13 is fixedly connected to the other side of the arc plate 11. A clamping plate 14 is fixedly connected to the top of the adjustment block 13. A slot 15 is provided on the inner side of the clamping plate 14. The four sets of arc plates 11 are connected end to end in sequence through a connecting plate.

[0046] The support plate 2 includes two sets of side plates 21. A mounting hole 22 is provided on the side of the side plate 21 away from the rotating sleeve 1. The two sets of side plates 21 are assembled by a connecting plate.

[0047] The bottom plate 3 includes two sets of panels 31. A jack 32 is mounted on one side of the panel 31 close to the support plate 2. The two sets of panels 31 are assembled together through a connecting plate.

[0048] The rotating sleeve 1 is rotatably connected to the top of the support plate 2, and the output end of the jack 32 is locked into the mounting hole 22. By fitting the rotating sleeve 1 onto the outside of the brake 100, with the retaining slot 15 aligned with the handle 101 of the brake 100, the position of the clamping plate 14 is adjusted by rotating the adjustment block 13, and the retaining slot 15 secures the handle 101 of the brake 100. Activating the jack 32 pushes the support plate 2 upward, simultaneously raising the rotating sleeve 1 and completing the removal of the brake 100. Finally, by grasping the air duct 102, the brake 100 is rotated 90 degrees to ensure smooth removal.

[0049] As an example provided, Figure 6 The adjusting block 13 includes a bottom block 131 fixedly connected to the side of the arc plate 11 where the groove 12 is not provided, a top block 132 slidably connected to the bottom end of the bottom block 131, and an adjusting bolt 133 provided inside the bottom block 131;

[0050] The adjusting bolt 133 is rotated to adjust the position of the top block 132 at the top of the bottom block 131. The sliding contact surface between the bottom block 131 and the top block 132 is an inclined surface, and the inclined surface is tilted downward from the adjusting bolt 133 toward the clamping plate 14. Rotating the adjusting bolt 133 can drive the top block 132 to move at the top of the bottom block 131. When the handle 101 of the brake 100 needs to be fixed, the adjusting bolt 133 is rotated forward, which drives the clamping plate 14 to move from the axis of the rotating sleeve 1 toward the outer diameter of the rotating sleeve 1, thereby gradually achieving the clamping plate 14 engaging the inner wall of the handle 101. Furthermore, because the sliding contact surface between the bottom block 131 and the top block 132 is an inclined surface, the top block 132 gradually deflects upward as it slides toward the outer diameter of the rotating sleeve 1, ensuring stability and securement of the brake 100 after it is fixed.

[0051] As an example provided, Figure 6 The clamping slot 15 includes a circular hole 151 and a U-shaped groove 152. The diameter of the circular hole 151 is larger than the opening diameter of the U-shaped groove 152, and the circular hole 151 is closer to the connection end between the clamping plate 14 and the adjustment block 13 relative to the U-shaped groove 152. During the initial installation of the rotating sleeve 1, the circular hole 151 ensures that the clamping plate 14 can be located inside the handle 101 of the brake 100. When the control adjustment block 13 drives the clamping plate 14 to tighten the brake 100, the clamping plate 14 slides toward the outer diameter of the rotating sleeve 1 and deflects upward, so that the U-shaped groove 152 can be clamped on the inside of the handle 101 of the brake 100, thereby completing the fixation of the brake 100.

[0052] Furthermore, since the diameter of the circular hole 151 is larger than the opening diameter of the U-shaped groove 152 , it can be ensured that after installation is completed, the clamping plate 14 cannot be separated from the handle 101 of the brake 100 , thereby improving the fastening performance.

[0053] Moreover, the fastening method of moving from the axis of the rotating sleeve 1 toward the outer diameter of the rotating sleeve 1 and offsetting upward can not only improve the fastening, but also increase the distance between the brake 100 and the support plate 2 as much as possible after the fastening is completed, thereby ensuring the smoothness of subsequent work and reducing the risk of friction generated by the brake 100.

[0054] As an example provided, Figures 7 to 9The side plate 21 near the rotating sleeve 1 has an arc groove 23, in which a ball 24 is disposed. The groove 12 fits against the top of the ball 24, and the rotating sleeve 1 rotates by cooperating with the ball 24 through the groove 12. By fitting the groove 12 at the bottom end of the arc plate 11 over the top of the ball 24, after the brake 100 is lifted, the air duct 102 of the brake 100 is gripped and rotated. At this time, the ball 24 adaptively rolls inside the arc groove 23, easily completing a 90-degree rotation of the brake 100. This ensures that the brake 100 avoids contact and friction with obstacles during final removal, greatly improving the overall disassembly efficiency.

[0055] As an example provided, Figures 7 to 9 A limit block 25 is screwed onto the side of the side plate 21 near the rotating sleeve 1. The inner side of the limit block 25 is threadedly connected to a limit bolt 251. The position of the limit bolt 251 is adjusted by rotating it. When the rotating sleeve 1 is installed on the top of the support plate 2, the limit bolt 251 is rotated to contact the side wall of the arc plate 11, thereby limiting the position of the rotating sleeve 1, ensuring that the rotating sleeve 1 does not deviate during rotation, and ensuring that friction due to deviation is not generated during the removal of the final brake 100.

[0056] As an example provided, Figures 10 to 12 A guide wheel 33 is mounted on the side of the panel 31 away from the support plate 2. A first fixing plate 34 and a second fixing plate 35 are fixedly connected to the two sides of the panel 31. By positioning the guide wheel 33 on the guide block 51 of the guide frame 5, the stability of the movement of the base plate 3 is improved. The first fixing plate 34 is connected to the threaded block 533, and the second fixing plate 35 is connected to the auxiliary wheel 54.

[0057] In summary, the rotating sleeve 1 is placed over the outside of the brake 100. The rotating sleeve 1 is composed of four sets of arc plates 11. A groove 12 is formed on one side of the arc plate 11, and an adjustment block 13 is fixedly connected to the other side. The top of the adjustment block 13 is fixedly connected to the clamping plate 14. The inner side of the clamping plate 14 has a locking groove 15. The position of the clamping plate 14 is adjusted by the adjustment block 13 so that the locking groove 15 is directly opposite the handle 101 of the brake 100, thereby achieving a limited fixation of the brake 100. The support plate 2 includes two sets of side plates 21. The side plates 21 have mounting holes 22 and arc grooves 23. A ball 24 is disposed in the arc groove 23. The groove 12 cooperates with the ball 24 to achieve rotation of the rotating sleeve 1. The base plate 3 includes two sets of panels 31. A jack 32 is installed on the side of the panel 31 close to the support plate 2. The output end of the jack 32 is clamped in the mounting hole 22. The jack 32 is started to push the support plate 2 up, driving the rotating sleeve 1 and the brake 100 to rise to complete the disassembly. Finally, the brake 100 is driven to rotate 90 degrees by holding the air duct 102 to ensure smooth unloading.

[0058] As an example provided, Figure 1 、 Figures 13 to 15 A lifting vehicle, comprising a disassembly mechanism, further comprising:

[0059] The vehicle body 4 has a platform top provided with a slide rail 41, and a slider 42 is provided at the top of the slide rail 41;

[0060] The guide frame 5 has a guide block 51 fixedly connected to its top end. A guide slot 52 is defined on one side of the guide frame 5. The guide frame 5 is fixedly connected to the top end of the slider 42. After the disassembly mechanism has completed lifting the brake 100 and rotating it 90 degrees, the driving member 53 of the guide frame 5 can drive the bottom plate 3 to move and gradually position it above the vehicle body 4, thereby completing the disassembly of the brake 100.

[0061] The operator pushes the guide frame 5 to enable the slider 42 at the bottom end of the guide frame 5 to slide on the slide rail 41 .

[0062] As an example provided, Figure 13 、 Figure 14 The two sides of the vehicle body 4 are rotatably connected with side rods 43, and one end of the side rods 43 is provided with a support rod 44. When the device is in operation, the side rods 43 are rotated to unfold them, and the support rods 44 can improve the stability of the entire device, ensuring the smooth disassembly of the brake 100.

[0063] As an example provided, Figure 13 、 Figure 14 A driving member 53 is provided on the other side of the guide frame 5 where the guide slot 52 is provided. The driving member 53 includes a motor 531 mounted on the outside of the guide frame 5, a screw rod 532 fixedly connected to the output end of the motor 531, and a threaded block 533 disposed on the outside of the screw rod 532. One side of the threaded block 533 is in contact with the guide frame 5. By starting the motor 531, the screw rod 532 can be driven to move. By rotating the screw rod 532, the threaded block 533 can be driven to adjust its position, thereby adjusting the position of the base plate 3 connected to the threaded block 533.

[0064] As an example provided, Figure 14 、 Figure 15 An auxiliary wheel 54 is provided inside the guide groove 52, and a screw rod 541 is fixedly connected to one side of the auxiliary wheel 54. By inserting the screw rod 541 into the mounting hole of the second fixing plate 35 and restraining it with a nut, the auxiliary wheel 54 can ensure smooth movement when the base plate 3 moves along the guide frame 5.

[0065] In summary, the operator pushes the guide frame 5 to enable the slider 42 to slide on the slide rail 41. A drive member 53 is provided on the other side of the guide slot 52 of the guide frame 5. This drive member comprises a motor 531, a screw 532, and a threaded block 533. The threaded block 533 is connected to the base plate 3. Starting the motor 531 rotates the screw 532, which in turn moves the threaded block 533, thereby adjusting the position of the base plate 3. An auxiliary wheel 54 is also provided on the inner side of the guide slot 52. A screw 541 is fixedly connected to one side of the auxiliary wheel 54. When the base plate 3 moves along the guide frame 5, the auxiliary wheel 54 ensures smooth movement.

[0066] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
