Description

Technical Field

[0001] This utility model relates to the field of automobile repair, and in particular to a novel automobile repair lifting device. Background Technology

[0002] An existing patent (publication number: CN204224169U) discloses an automotive repair lifting device, including a lifting platform plate, a sleeve, a lifting shaft, and a hydraulic drive device. The lifting platform plate is fixed to the upper end of the lifting shaft, and the lower end of the lifting shaft is connected to the hydraulic drive device. The lifting shaft is provided with a support rod and is disposed within the sleeve. The sleeve has a vertical sliding groove and a horizontal support groove, which are connected. The horizontal support groove is disposed above the vertical sliding groove, and the support rod protrudes from the outer surface of the sleeve. However, this device lacks a wheel limiting mechanism on the "lifting platform plate," which cannot guarantee that the vehicle will not slip during vehicle lifting and repair, posing a safety hazard. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a novel automotive repair lifting device that offers smooth lifting and positioning protection to prevent accidental drop of the carrier plate. Furthermore, by adding a wheel limiting mechanism, it prevents the vehicle from slipping during lifting and maintenance, thereby reducing safety hazards and improving the safety of automotive repair operations.

[0004] The objective of this utility model is achieved through the following technical solution: A novel automotive repair lifting device includes a fixed base, an inclined plate, a carrier plate, a support rod, a limiting plate, a rotating sleeve, and a worm gear. The carrier plate has mounting blocks on both sides, and each mounting block has a sliding track. The sliding track is adapted to the limiting plate, and the limiting plate is connected to the sliding track, allowing it to slide within the track. A control rod is threadedly connected inside the limiting plate, and the lower end of the control rod has a rotating rod that passes through the mounting block. The rotating rod is connected to the rotating sleeve by screws, and the screws sequentially connect the rotating sleeve and the rotating rod. The upper side of the rotating sleeve is fitted to the mounting block, and the lower side of the rotating sleeve has a worm gear adapted to the worm gear and connected to it.

[0005] The present invention describes a carrier plate externally fitted with a rotating wheel, the rotating wheel having a drive rod, the carrier plate having a side through hole, the drive rod being adapted to the side through hole, the drive rod passing through the side through hole, the drive rod being connected to the outer end of a worm gear, the inner end of the worm gear being connected to a bracket, the bracket being connected to a mounting block, the inner side of the bracket having a retaining plate, the worm gear having a retaining groove, the retaining plate being adapted to the retaining groove, and the retaining plate being connected to the retaining groove.

[0006] The carrier plate of this utility model has positioning plates on both sides, and positioning sleeves are provided on the outside of the positioning plates. The positioning sleeves are connected to positioning rods by threads. The positioning rods pass through the positioning sleeves, and the outer end of the positioning rods has a knob. The inner end of the positioning rods is connected to a locking block. Beneficial effects

[0007] The inclined panels on both sides of the fixed base of this utility model facilitate the smooth driving of vehicles onto the carrier. When the carrier is lowered to its maximum extent, the mounting plate falls onto the upper part of the fixed upright plate, which can enhance the stability of the carrier support. The positioning plate rises and falls with the carrier and slides vertically along the direction of the support rod, preventing the carrier from shifting or tilting, improving its stability for vehicle load-bearing, and by raising the bottom of the vehicle, it facilitates maintenance work for operators.

[0008] This invention provides dual protection for the positioning of the carrier plate through hydraulic cylinder drive and mechanical locking. The hydraulic cylinder, with its piston rod, drives the carrier plate to rise and fall smoothly, providing stable power. The locking block and locking groove are embedded and engaged to brake and lock the height of the carrier plate after it has been raised or lowered, preventing the carrier plate from falling accidentally and improving the safety of the device.

[0009] The meshing transmission between the worm gear and worm shaft, combined with the threaded positioning between the control rod and the limiting plate, and the limiting guide between the limiting plate and the slide, allows the corresponding limiting plate to be raised and lowered longitudinally by rotating the rotating wheel. After the plate rises, it limits the position of the front and rear wheels of the vehicle, preventing the vehicle from slipping during lifting and maintenance, reducing safety hazards, and improving the safety of automobile maintenance operations. When the limiting plate descends to the point where its upper surface is parallel to the upper surface of the plate, it facilitates the entry and exit of vehicles.

[0010] This utility model features smooth lifting and positioning protection to prevent the carrier plate from falling accidentally. In addition, by adding a wheel limiting mechanism, it prevents the vehicle from slipping during lifting and maintenance, reducing safety hazards and improving the safety of automobile maintenance operations.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: Example 1: A novel car repair lifting device includes a fixed base 01, an inclined plate 03, a carrier plate 04, a support rod 08, a limiting plate 14, a rotating sleeve 19, and a worm gear 21. The carrier plate 04 has mounting blocks 16 on both sides, and each mounting block 16 has a slide rail 15 inside. The slide rail 15 is adapted to the limiting plate 14, and the limiting plate 14 is connected to the slide rail 15, sliding within the slide rail 15. A control rod 17 is threadedly connected inside the limiting plate 14, and the lower end of the control rod 17 has a rotating rod 18 that passes through the mounting block 01. 6. The rotating rod 18 is connected to the rotating sleeve 19 by screws 20. The screws 20 are connected to the rotating sleeve 19 and the rotating rod 18 in sequence. The upper side of the rotating sleeve 19 is fitted with the mounting block 16. The lower side of the rotating sleeve 19 has a worm gear 22, which is compatible with the worm 21 and is connected to the worm 21. This device lifts and lowers smoothly and is equipped with positioning protection to prevent the carrier plate 04 from falling accidentally. At the same time, by adding a wheel limiting mechanism, it prevents the vehicle from slipping during lifting and maintenance, reduces safety hazards, and improves the safety of automobile maintenance operations.

[0022] Example 2: The carrier plate 04 of this utility model is externally attached to the rotating wheel 25. The rotating wheel 25 has a drive rod 23. The carrier plate 04 has a side through hole 24. The drive rod 23 is adapted to the side through hole 24 and passes through the side through hole 24. The drive rod 23 is connected to the outer end of the worm gear 21. The inner end of the worm gear 21 is connected to the bracket 26. The bracket 26 is connected to the mounting block 16. The inner side of the bracket 26 has a retaining plate 27. The worm gear 21 has a retaining groove 28. The retaining plate 27 is adapted to the retaining groove 28 and is connected to the retaining groove 28.

[0023] Example 3: The carrier plate 04 of this utility model has positioning plates 29 on both sides. The positioning plates 29 have positioning sleeves 12 on the outside. The positioning sleeves 12 are connected to positioning rods 13 by threads. The positioning rods 13 pass through the positioning sleeves 12. The outer end of the positioning rods 13 has a knob 11. The inner end of the positioning rods 13 is connected to a locking block 10. The meshing transmission between the worm gear 22 and the worm 21 cooperates with the threaded positioning between the control rod 17 and the limiting plate 14 and the limiting guide between the limiting plate 14 and the slide rail 15. This allows the corresponding limiting plate 14 to be raised and lowered longitudinally by rotating the rotating wheel 25. After the carrier plate 04 is raised, it limits the position of the front and rear wheels of the vehicle, preventing the vehicle from slipping during the raising, lowering and maintenance process, reducing safety hazards and improving the safety of automobile maintenance operations. When the limiting plate 14 is lowered to the point where its upper surface is parallel to the upper surface of the carrier plate 04, it facilitates the vehicle to drive in and out.

[0024] Example 4: The support rod 08 of this utility model passes through the positioning plate 29, and the lower end of the support rod 08 is connected to the fixing seat 01. The support rod 08 has multiple locking grooves 09, which are adapted to the locking block 10. The locking block 10 is connected to the locking groove 09 and driven and mechanically locked by the hydraulic cylinder 05, providing double protection for the positioning of the carrier plate 04. The hydraulic cylinder 05 is a piston rod 06 that drives the carrier plate 04 to rise and fall smoothly, providing stable power. The locking block 10 and the locking groove 09 are embedded and engaged, which brakes and locks the height of the carrier plate 04 after it is raised and lowered, preventing the carrier plate 04 from falling accidentally and improving the safety of the device.

[0025] Example 5: The fixed base 01 of this utility model is connected to a hydraulic cylinder 05. The hydraulic cylinder 05 is provided with a piston rod 06, which is connected to a carrier plate 04. The carrier plate 04 has a ramp 07 at both ends. The fixed base 01 has fixed upright plates 02 on both sides. The fixed upright plates 02 are connected to inclined panels 03 on the outside. The ramp 07 is connected to the upper part of the fixed upright plates 02. The inclined panels 03 on both sides of the fixed base 01 facilitate the smooth entry of the vehicle into the carrier plate 04. When the carrier plate 04 is lowered to its maximum extent, the ramp 07 falls onto the upper part of the fixed upright plates 02, which can enhance the support stability of the carrier plate 04. The positioning plate 29 rises and falls with the carrier plate 04 and slides vertically along the direction of the support rod 08 to prevent the carrier plate 04 from shifting or tilting, thereby improving its stability for vehicle load-bearing. By raising the bottom of the vehicle, it is convenient for operators to carry out maintenance work.

The upper surface of the rotating sleeve 19 is in contact with the lower surface of the mounting block 16. Then, place the worm gear 21 and rotating wheel 25 on the inner and outer sides of the carrier plate 04, respectively. The drive rod 23 passes through the side through hole 24 and is fixedly connected to the worm gear 21. The worm gear 21 and worm wheel 22 are aligned and connected. Then, place the bracket 26 outside the worm gear 21 and fix it to the mounting block 16. The retaining plate 27 is embedded in the retaining groove 28. Then, place the limiting plate 14 into the slide rail 15 and fit the limiting plate 14 over the control rod 17. The mounting plate 04 is assembled and then positioned by threads. The locking block 10 and the knob 11 are placed on the inner and outer sides of the positioning plate 29, respectively. The positioning support rod 13 passes through the positioning support sleeve 12 and is fixedly connected to the locking block 10. The positioning support rod 13 is fixedly connected to the positioning support sleeve 12 by threads. After the mounting plate 04 is assembled, the hydraulic cylinder 05 is installed and fixed on both sides of the fixed base 01. Then the mounting plate 04 is placed on the upper part of the fixed base 01, and the upper end of the piston rod 06 is fixedly connected to the mounting plate 04.
