Description

Technical Field

[0001] This utility model relates to the field of wheel and axle lifting technology, and in particular to a lifting wheel and axle assembly structure. Background Technology

[0002] A wheel and axle system, as the name suggests, is a system composed of a "wheel" and an "axle". This system can rotate around a common axis, which is equivalent to a lever system with the axis as the fulcrum and the radius as the rod. It is commonly found in everyday machinery such as windlasses and winches.

[0003] Patent publication number CN218663119U discloses an automatically adjustable wheel axle lifting structure, including a frame. A cylinder is snapped into the frame, and a push plate is fixedly connected to the other end of the cylinder. Two connecting plates overlap the push plate, and slots are formed on the opposite surfaces of the two connecting plates. Two guide grooves are formed on one side of the connecting plate on the right side, and two connecting rods are snapped into the two guide grooves respectively. Slider blocks are fixedly connected to the opposite sides of the two connecting plates, and the two sliders are slidably connected in two sliding grooves respectively. The two sliding grooves are respectively formed on the opposite surfaces of the two bases. By setting up the cylinder, connecting plates, and connecting rods, the wheel axle structure under the running box can be lifted by the lifting structure, so that the wheel axle structure can be retracted into the interior of the running box. This avoids the wheel axle structure under the running box from obstructing the transport box when the running boxes are stacked or stored.

[0004] The above devices adjust the height of the wheel axle by controlling the overall height of the wheel axle with a cylinder when raising or lowering it. In actual use, since the cylinder needs to bear the function of raising and lowering and providing support after adjustment, the lifting function will not work smoothly when the cylinder is damaged, which has great limitations. Therefore, a lifting wheel axle assembly structure is proposed to solve the above problems. Utility Model Content

[0023] 1. A lifting wheel axle assembly structure, through the design of an adjustment mechanism, controls the rotation of the threaded adjustment rod to drive the lifting plate to adjust its height. After the motor is working, it drives the threaded adjustment rod to rotate through a rectangular rod. If the motor fails or cannot properly perform the lifting control, the rotation of the threaded adjustment rod can also be adjusted by controlling the rotation of the rotating rod. Thus, it can be adjusted through both electric and manual adjustment methods. The lifting operation can still be performed when the motor fails, effectively ensuring the smooth operation of the lifting work.

[0024] 2. A lifting wheel axle assembly structure, through the design of the clamping assembly, after the adjustment step is completed, the cylinder works and pushes the control plate, causing the trapezoidal block to squeeze the inclined surface inside the trapezoidal groove to form a pushing effect.

[0032] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 The present invention will be described in further detail below.

[0033] This utility model discloses a lifting wheel axle assembly structure. (Refer to...) Figures 1-6 It includes a wheel axle body 1, a connecting plate 2 rotatably connected to the outside of the wheel axle body 1, a frame plate 3 provided on the top of the connecting plate 2, an adjustment mechanism 4 provided on the frame plate 3, the adjustment mechanism 4 includes a lifting plate 41, the lifting plate 41 is provided inside the frame plate 3, and the lifting plate 41 penetrates the bottom wall of the frame plate 3.

[0034] A socket 42 is fixedly connected to the top of the connecting plate 2. The lifting plate 41 extends into the socket 42 and matches the socket 42. A threaded adjusting rod 43 is rotatably connected to the inner side of the frame plate 3. The threaded adjusting rod 43 passes through the top wall of the lifting plate 41 and is threadedly connected to the lifting plate 41. A rectangular groove 44 is opened at the top of the threaded adjusting rod 43. A rotating rod 45 is provided on the inner side of the frame plate 3. The rotating rod 45 extends out of the outer side of the frame plate 3 and is rotatably connected to the frame plate 3. A first bevel gear 46 is fixedly connected to the outside of the threaded adjusting rod 43. A second bevel gear 47 is fixedly connected to one end of the rotating rod 45. The second bevel gear 47 is located on the top of the first bevel gear 46 and meshes with the first bevel gear 46. A motor frame 48 is provided on the top of the frame plate 3. A motor 49 is fixedly connected inside the motor frame 48.

[0035] The motor 49 is fixedly connected to a rectangular rod 491 via an output shaft. The rectangular rod 491 extends into and matches the rectangular groove 44. After the threaded adjusting rod 43 is rotated, it drives the lifting plate 41 to adjust its height. After the motor 49 is working, it drives the threaded adjusting rod 43 to rotate via the rectangular rod 491. If the motor 49 fails or cannot properly perform the lifting control, the rotation rod 45 can be controlled to rotate to adjust the rotation of the threaded adjusting rod 43. This allows for adjustment through both electric and manual methods. The lifting operation can still be performed even when the motor 49 fails, effectively ensuring the smooth operation of the lifting work.

[0036] The motor frame 48 has grooves 492 on both sides of its side walls. The top of the frame plate 3 has two vertical plates 493 integrally formed. The motor frame 48 is positioned between the two vertical plates 493 and fits snugly against the vertical plates 493. A U-shaped plate 494 is fixedly connected to one side of the vertical plate 493. The vertical plate 493 provides mounting support for the motor 49. A positioning block 495 is slidably connected to the inside of the U-shaped plate 494. The positioning block 495 passes through the vertical plate 493 and extends into the groove 492, matching the groove 492. A threaded control rod 496 is rotatably connected to one side of the positioning block 495. The threaded control rod 496 passes through one side wall of the U-shaped plate 494 and is threadedly connected to the U-shaped plate 494. When the threaded adjusting rod 43 rotates, it drives the positioning block 495 to move.

[0037] An L-shaped fixing plate 497 is provided on one side of the connecting plate 2. The L-shaped fixing plate 497 passes through the socket 42 and the lifting plate 41 in sequence. The L-shaped fixing plate 497 fixes the lifting plate 41 on the connecting plate 2. Two locking blocks 498 are slidably connected inside the L-shaped fixing plate 497. The locking blocks 498 extend out of the outer side of the L-shaped fixing plate and fit against one side of the socket 42. A spring 499 is fixedly connected inside the L-shaped fixing plate 497. The spring 499 is fixedly connected to one side of the locking block 498 and the spring 499 exerts an elastic force on the locking block 498.

[0038] A clamping assembly 5 is provided on the frame plate 3. The clamping assembly 5 includes two auxiliary frames 51, which are fixedly connected to the left and right sides of the lifting plate 41, respectively. A clamping plate 52 is provided on both sides of the frame plate 3. The clamping plate 52 extends into the auxiliary frame 51 and matches the auxiliary frame 51. A support plate 53 is fixedly connected to the front side of the lifting plate 41. A control plate 54 is provided inside the support plate 53. The control plate 54 extends out of the support plate 53. Trapezoidal rods are fixedly connected to both ends of the control plate 54. The clamping plate 52 has a trapezoidal groove 56 inside the block 55. The trapezoidal block 55 extends into the trapezoidal groove 56 and matches the trapezoidal groove 56. After the trapezoidal block 55 enters the trapezoidal groove 56, it can squeeze and push the inclined side wall inside the trapezoidal groove 56. A cylinder 57 is fixedly connected to the support plate 53. One end of the cylinder 57 is fixedly connected to the control plate 54. A guide rod is fixedly connected to the control plate 54. The guide rod passes through the support plate 53. After the cylinder 57 works, it pushes and pulls the control plate 54.

[0039] In actual operation, when this device is used, first connect the power supply to the device, control the threaded adjusting rod 43 to rotate, the threaded adjusting rod 43 drives the lifting plate 41 to adjust the height, the lifting plate 41 drives the L-shaped fixing plate 497 to move, the L-shaped fixing plate 497 drives the socket 42 to move. Thus, through the above connection relationship, it can be seen that the wheel axle body 1 can be adjusted in height. When controlling the threaded adjusting rod 43 to rotate, the motor 49 can be controlled to work, the motor 49 drives the rectangular rod 491 to rotate, and the rectangular rod 491 drives the threaded adjusting rod 43 to rotate for adjustment. If the motor 49 is damaged or needs to be removed for maintenance, in order to ensure the smooth operation of the lifting adjustment, the rotating rod 45 can be manually controlled to rotate, the rotating rod 45 drives the second bevel gear 47 to rotate, the second bevel gear 47 drives the first bevel gear 46 to rotate, and the first bevel gear 46 drives the threaded adjusting rod 43 to rotate, thereby realizing the lifting control of both motor 49 and manual adjustment.

[0040] In the above lifting and adjusting process, in order to improve the stability after adjustment, after the adjustment steps are completed, the cylinder 57 works and pushes the control plate 54. The control plate 54 drives the trapezoidal block 55 to move deeper into the trapezoidal groove 56, causing the trapezoidal block 55 to squeeze the inclined surface inside the trapezoidal groove 56 to form a pushing effect. At this time, the clamping plate 52 moves into the auxiliary frame 51 until the clamping plate 52 is tightly attached to the outer wall of the frame plate 3. The two have a large friction force, which can effectively ensure the stability after adjustment.

[0041] Finally, this device can be flexibly disassembled and assembled. When it is necessary to remove the motor 49, after rotating the threaded control rod 496, the threaded control rod 496 drives the positioning block 495 to move away from the groove 492, and the motor frame 48 can be taken out to complete the removal of the motor 49. Secondly, if it is necessary to remove the wheel axle body 1, after pushing the locking block 498 on the L-shaped fixing plate 497 into the L-shaped fixing plate 497, after pulling the L-shaped fixing plate 497 out of the socket 42, the lifting plate 41 can be separated from the socket 42. This flexible disassembly and assembly is conducive to the maintenance and inspection work and improves the flexibility of use.

[0042] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
