Description

Technical Field

[0001] This utility model relates to the field of wind-powered vehicle jacking technology, specifically an adjustable wind-powered vehicle jack. Background Technology

[0002] The adjustable pneumatic vehicle lifting machine, equipped with a walking device, can move flexibly according to the needs of the operation, adapt to different working environments and positions, and has a built-in lifting rod that can move up and down to ensure the stability and accuracy of the lifting process, making it suitable for lifting operations of various vehicles.

[0003] In existing technology, cylinders are used as the core component of the car-lifting machine to provide lifting and support power. Casters at the bottom ensure the structural stability and movement coordination of the entire car-lifting machine. However, in actual use, during the lifting process of the cylinders, and when the cylinders lose power, the lack of a fall protection device at the bottom can easily cause maintenance parts to fall and cause serious damage to the equipment itself, thus increasing subsequent maintenance costs and time. In addition, during the unloading process, the device is only supported by the casters at the bottom, which makes the overall stability of the device poor and inconvenient for loading and unloading of processed parts. Therefore, there is a need to improve the adjustable pneumatic car-lifting machine. Utility Model Content

[0007] The anti-fall assembly includes a connecting sleeve, which is fixedly connected to the top of the cylinder. A limit post is movably connected to the inner side of the connecting sleeve. An adjusting rod is fixedly connected to the top of the limit post. A rotating ring is rotatably connected to the bottom of the adjusting rod. A flexible rubber post is located at the end of the adjusting rod away from the limit post. A pull rod is fixedly connected to the outer ring of the rotating ring.

[0008] Preferably, the rotating ring is rotatably connected to the top of the cylinder, and a groove is provided at the corresponding position of the limiting post and the connecting sleeve, and the limiting post is movably connected in the groove, so as to synchronously drive the adjusting rod to rotate.

[0009] Preferably, a groove is provided at the position corresponding to the top of the cylinder on the fastening bolt, and the bottom of the fastening bolt abuts against the bottom of the groove, which facilitates fixing the flexible rubber column after it has been moved.

[0010] Preferably, the support assembly includes a sliding column, which is fixedly connected inside the connecting frame. A slider is slidably connected to the outside of the sliding column. A connecting rod is rotatably connected to the top of the slider. A support plate is rotatably connected to the top of the connecting rod. A rubber pad is fixedly connected to the top of the support plate. A first spring is fixedly connected between the slider and the connecting frame. A first damper is fixedly connected between the bottom of the support plate and the top of the connecting frame. A second spring is fixedly connected between the bottom of the support plate and the top of the connecting frame. This facilitates buffering and fixing in the event of overall device failure, thereby protecting the device and equipment.

[0011] Preferably, a groove is provided at the corresponding position of the slider and the connecting frame, and the slider is slidably connected in the groove, which facilitates the improvement of the stability of the support plate.

[0012] Preferably, the stabilizing mechanism includes a worm gear rotatably connected inside the connecting seat.

[0014] Compared with the prior art, this utility model provides an adjustable pneumatic vehicle frame machine, which has the following features:

[0015] Beneficial effects:

[0016] 1. This adjustable pneumatic jacking machine, through its anti-fall support mechanism, releases the fastening bolts from the cylinder. By pulling the lever to the left, the outer flexible rubber column comes into contact with the cylinder output end, forming a friction fixation. This further prevents the maintenance parts lifted on top from suddenly falling when the cylinder loses power. When the maintenance parts on top are too heavy and the flexible rubber column loses its function, the falling maintenance parts will first contact the rubber pad, which will then compress the first and second springs. This allows the first damper to absorb the energy from the impact, thus avoiding damage to the maintenance parts and the equipment itself, reducing subsequent maintenance costs and time.

[0017] 2. This adjustable pneumatic car-mounting machine, through its stabilizing mechanism, rotates a worm gear when unloading is required. The worm gear drives a worm wheel to rotate, which in turn drives a screw to rotate. During the rotation of the screw, the lifting plate moves upward, thereby retracting the casters into the connecting seat. This increases the contact area between the connecting seat and the ground, further improving the overall stability of the device. Attached Figure Description

[0027] Example 1:

[0028] Please see Figure 1-5 This utility model provides a technical solution: an adjustable wind-powered vehicle frame, including a connecting seat 1, a connecting frame 2 fixedly connected to the top of the connecting seat 1, a handle 3 fixedly connected to the left side of the connecting frame 2, a stabilizing mechanism 4 inside the connecting seat 1, a cylinder 5 fixedly connected to the top of the connecting seat 1, and an anti-fall support mechanism 6 on the top of the cylinder 5.

[0029] The fall protection support mechanism 6 includes a fall protection component 61 and a support component 62, with the support component 62 located to the left and right of the fall protection component 61.

[0030] The fall arrestor assembly 61 includes a connecting sleeve 611, which is fixedly connected to the top of the cylinder 5. A limit post 612 is movably connected to the inner side of the connecting sleeve 611. An adjusting rod 613 is fixedly connected to the top of the limit post 612. A rotating ring 615 is rotatably connected to the bottom of the adjusting rod 613. A flexible rubber post 614 is located at the end of the adjusting rod 613 away from the limit post 612. A pull rod 616 is fixedly connected to the outer ring of the rotating ring 615. A fastening bolt 617 is threaded inside the pull rod 616, which facilitates a secondary fixing effect after the cylinder 5 is raised or lowered, thereby improving the overall stability of the device.

[0031] Furthermore, the rotating ring 615 is rotatably connected to the top of the cylinder 5, and the limiting post 612 and the connecting sleeve 611 are respectively provided with grooves, and the limiting post 612 is movably connected in the groove, so as to synchronously drive the adjusting rod 613 to rotate.

[0032] Furthermore, a groove is provided at the position corresponding to the top of the cylinder 5 on the fastening bolt 617, and the bottom of the fastening bolt 617 abuts against the bottom of the groove, which facilitates fixing the flexible rubber column 614 after it has been moved.

[0033] Furthermore, the support assembly 62 includes a sliding column 621, which is fixedly connected inside the connecting frame 2. A slider 622 is slidably connected to the outside of the sliding column 621. A connecting rod 624 is rotatably connected to the top of the slider 622. A support plate 625 is rotatably connected to the top of the connecting rod 624. A rubber pad 626 is fixedly connected to the top of the support plate 625. A first spring 623 is fixedly connected between the slider 622 and the connecting frame 2. A first damper 627 is fixedly connected between the bottom of the support plate 625 and the top of the connecting frame 2. A second spring 628 is fixedly connected between the bottom of the support plate 625 and the top of the connecting frame 2. This facilitates buffering and fixing in the event of overall device failure, thereby protecting the device and equipment.

[0034] Furthermore, a groove is provided at the corresponding position of the slider 622 and the connecting frame 2, and the slider 622 is slidably connected in the groove, which facilitates the improvement of the stability of the support plate 625.

[0035] Example 2:

[0036] Please see Figure 5 Furthermore, in conjunction with Embodiment 1, the stabilizing mechanism 4 includes a worm gear 41, which is rotatably connected inside the connecting seat 1. A worm wheel 42 is meshed on the back of the worm gear 41. A screw 43 is fixedly connected to the bottom of the worm wheel 42. A lifting plate 44 is threadedly connected to the outside of the screw 43. A second damper 46 is fixedly connected to the inner side of the top of the lifting plate 44. A caster 48 is fixedly connected to the bottom of the second damper 46. A third spring 47 is fixedly connected between the caster 48 and the lifting plate 44 to improve the stability of the device during the unloading process.

[0037] Furthermore, a through groove is provided at the corresponding position of the lifting plate 44 and the connecting seat 1, and the lifting plate 44 is slidably connected in the through groove, and the worm gear 42 is rotatably connected to the inner side of the top of the connecting seat 1, so as to drive the caster 48 to move up and down.

[0038] In actual operation, when the device is in use, firstly, after the maintenance parts are placed at the output end of cylinder 5 and lifted, they are transported to the designated position via casters 48 and then stopped. During the movement, the anti-fall support mechanism 6 releases the fastening bolt 617 from cylinder 5. Then, by pulling the pull rod 616 to the left, the pull rod 616 drives the rotating ring 615 to rotate. As the rotating ring 615 moves, it drives the rotating adjusting rod 613 to rotate at the connection point between the limit post 612 and the connecting sleeve 611. This causes the flexible rubber column 614 to gradually approach the output end of cylinder 5, so that the outer side of the flexible rubber column 614 abuts against the output end of cylinder 5, thus forming friction fixation. Then, by resetting the fastening bolt 617, the bottom of the fastening bolt 617 abuts against cylinder 5 again, completing the fixation of the pull rod 616 and further preventing... When the subsequent cylinder 5 loses power, the maintenance component lifted on its top suddenly falls. When the top maintenance component is too heavy and its flexible rubber column 614 loses its function, the falling maintenance component first contacts the rubber pad 626, thereby pushing the support plate 625 set at the bottom of the rubber pad 626 to move downward. This causes the support plate 625 to push the slider 622 connected to the bottom of the connecting rod 624 to move along the guide of the sliding column 621, thereby compressing the first spring 623 and the second spring 628, causing the first damper 627 to absorb the energy brought by the impact. Then, through the set stabilizing mechanism 4, when it is necessary to unload the part, the worm 41 is rotated, which drives the worm wheel 42 to rotate, and the worm wheel 42 drives the screw 43 to rotate. During the rotation of the screw 43, the lifting plate 44 moves upward, thereby retracting the caster 48 into the connecting seat 1.
