Description

Technical Field

[0001] This invention relates to the field of machinery, and more specifically, to a wheel-assisted lift. Background Technology

[0002] Car and truck maintenance often requires the regular removal and installation of wheels. A wheel with a tire is quite heavy, typically weighing 30-40 pounds. Furthermore, the wheel's circular shape makes it difficult for a single person to lift and move. During maintenance and repair, it's often necessary to lift the wheel off the ground and push it forward a few inches or a foot to precisely align it with the lug bolts on the rim. For auto mechanics, this involves removing and moving wheels multiple times a day, making it a physically demanding task that frequently results in back strains, finger pain, and other injuries.

[0025] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0026] See Figure 1 , Figure 2 and Figure 3 As shown, the wheel auxiliary lifting frame in this embodiment includes components such as wheel base frame 1, two columns 2, lifting structure 3, transmission structure 4, and tire buckle 5.

[0027] The wheel base 1 supports the entire structure and facilitates movement and transport. Two uprights 2 are fixed to the wheel base 1 to support the lifting structure 3 and transmission structure 4, among other components. The lifting structure 3 is mounted on the uprights 2 and moves up and down along the uprights under the drive of the transmission structure 4. The lifting structure 3 also serves to load wheels or tires. Tire clips 5 are used to press down the wheels or tires loaded on the lifting structure 3 during the movement of the wheel base 1.

[0028] See Figure 4 As shown, the wheel base 1 includes a base body 11 and multiple casters 12. The base body 11 has a U-shaped structure, with two sets of V-shaped connecting ends 111 at each end to fix a caster 12. The V-shaped connecting ends 111 contribute to the overall stability of the wheel base 1. The casters 12 facilitate smooth movement, and two of them are equipped with brakes. Bolt holes are provided on the base body 11 to connect two uprights. The wheel base 1 can be bolted to the front or back of the uprights, effectively adapting to the use in auto parts repair scenarios and meeting obstacle avoidance requirements. Meanwhile, as... Figure 8 As shown, the wheel base frame 1 can be installed in reverse according to lifting requirements, with a counterweight plate 9 on the base frame body 11 to maintain the necessary balance when the auxiliary lifting frame is under load. The edge of the counterweight plate 9 is placed directly on the edge of the base frame body 11.

[0029] Combination Figure 1 As shown, the lower ends of the two uprights 2 are respectively locked to the base frame body 11 of the wheel base frame 1 by fixing bolts. Several safety limiting grooves 21 are evenly distributed on the outward-facing side of the uprights 2. The safety limiting grooves 21 are used in conjunction with safety buckles to limit the movement after lifting and prevent it from falling off during descent, thereby increasing safety during use.

[0030] See Figure 6 The diagram shown is an exploded view of the lifting device structure. As shown, the lifting device structure 3 includes components such as the support body 31, the adjustable roller mechanism 32, and the guide pulley 33.

[0031] As shown in the figure, the main body 31 of the support includes a horizontal main rod 311 and two vertical sleeves 312. The two vertical sleeves 312 are respectively fitted onto two columns 2. A clearance is maintained between the vertical sleeves 312 and the columns to allow the vertical sleeves 312 to move up and down along the columns 2. Positioning holes are provided on the vertical sleeves 312. When the tire is raised to the required height, to prevent the tire from moving downwards due to gravity, a safety lock is inserted into the safety limit groove 21 through the positioning hole, effectively preventing the tire from shifting downwards and demonstrating a higher level of safety.

[0032] An adjustable roller mechanism 32 is horizontally arranged on the front surface of the transverse main rod 311. The adjustable roller mechanism 32 includes two horizontal roller assemblies 321 and a sliding tube 322 to form a support for supporting the wheel or tire.

[0033] In this embodiment, the horizontal roller assembly 321 includes a roller shaft 3211, a roller 3212, a bearing 3213, and a fixing spring 3214. The roller shaft 3211 is connected to the transverse main rod 311, and the transverse main rod 311 can also be provided with adjustment holes of different distances to accommodate tires of different diameters. The roller 3212 is connected to the roller shaft 3211 through the bearing 3214. Driven by the bearing 3214, the roller 3212 rotates, thereby driving the wheel / tire on the roller 3212 to rotate.

[0034] A sliding tube 322 is fitted onto the roller 3212. The sliding tube 322 is shorter than the roller 3212, and the inner diameter of the sliding tube 322 is larger than the outer diameter of the roller 3212. The roller 3212 has slots 32121 at both ends, and several protruding fixing springs 3214 are embedded in the slots 32121 to block the sliding tube 322, thus restricting its movement within the two ends of the roller 3212. The sliding tube 322 can be adjusted back and forth or rotated relative to the horizontal roller assembly 321 to allow the tire to move back and forth and also to drive the tire to rotate freely on it.

[0035] This facilitates the forward and backward movement of the wheels or tires, enabling convenient coordination with tire repair operations. The guide pulley 33 is fixed to the rear surface of the transverse main rod 311, located in the middle of the transverse main rod 311. The guide pulley 33 assists the transmission structure 4 in achieving the lifting of the entire transverse main rod 311.

[0036] Please see again Figure 5 The diagram shown is an exploded view of the transmission structure of the present invention. The transmission structure 4 includes components such as a support frame 41, a transmission belt guide 42, a pulley 43, a geared motor 44, a transmission belt 45, a brake box 46, and a hardware screw box 47.

[0037] Support frame 41 Figure 5As shown, the system includes a top plate 411 and a front cover plate 412. The top plate 411 and the front cover plate 412 are locked together by fasteners, maintaining an accommodating space between them. A belt guide 42 is installed at the top plate 411, through which a drive belt 45 passes. A pulley 43 is installed within the accommodating space. A brake box 46 and a hardware screw box 47 are fixed to the top plate 411 and the front cover plate 412. The first end of the drive belt 45 is fixed to the pulley 43 inside the brake box 46 by a pin. The other end passes through the belt guide 33 located on the transverse main rod of the lifting device after passing through the belt guide 4111, and then the tail end of the drive belt 45 is locked inside the belt guide 42 in the brake box 46. As shown, the pulley 43 can be operated either electrically or manually. Manual control involves connecting a manual wrench 6 to the pulley to manually rotate it. Electric control can be achieved by an electric drill. In order to reduce the speed of the lifting frame rising and falling too fast, a reduction motor 44 is connected to the end of the pulley 43 to keep the speed of rising or falling constant.

[0038] This invention also includes an adjustable braking mechanism. This braking mechanism comprises: a brake disc 431, a brake bracket 481, a brake pad 482, a compression spring 483, a brake bolt 484, and an adjusting nut 485. One end face of the pulley 43 protrudes to form the brake disc 431. The brake pad 482 is fixed to the brake disc 431. The pulley 43 is connected to the geared motor 44 via a bearing 432. The bearing 431 serves as a guide during brake disc installation, preventing misalignment and allowing for more flexible rotation of the brake disc. The brake bracket 481 is fixed in the middle to a support frame 41. One end of the brake bracket 481 is bent and extends to press against the brake pad 482. A compression spring fixing seat is located at the upper edge of the other end of the brake bracket 481. The bottom of the compression spring 483 is secured to the compression spring fixing seat. The top of the brake bolt 484 is fixed to the front cover plate 412. An adjusting nut 485 is provided on the stud of the brake bolt 484, passing over the compression spring 483. The position of the adjusting nut 485 compresses the compression spring 483, thereby adjusting the pressure on the brake bracket 481. Under this influence, the end of the brake bracket 481 corresponding to the brake pad will move closer to or further away from the brake pad, thus adjusting the pressure of the brake bracket on the brake pad. The braking mechanism provides continuous pressure to the brake pad through the compression spring and brake bracket, creating resistance when the brake disc rotates. This prevents the lifting frame from falling directly under load, offsetting the weight effect of increased load. The tension of this braking structure is adjustable. A handle 8 is provided at the support frame 41.

[0039] To secure the electric drill driving the geared motor 44, an adjustable drill chuck is provided behind the geared motor 44 to accommodate electric drills of different sizes. The adjustable drill chuck includes upper and lower drill mounting brackets 491 and connecting plates 492 on both sides, such as… Figure 1 and Figure 5 As shown, the electric drill mounting bracket 491 is connected by connecting pieces 492 on both sides. The electric drill mounting bracket 491 is provided with multiple adjustment mounting holes 493 to accommodate different models of electric drills. A wrench guard 494 is installed on the inner side of the electric drill mounting bracket 491 according to the electric drill model requirements, and an anti-collision sealing strip 495 is fitted on it to protect the surface of the electric drill wrench from damage.

[0040] Combination Figure 2 and Figure 7 As shown, one end of the tire buckle 5 of the present invention is sleeved on a column 2, and the other end of the tire buckle 5 is a fixing hook 52, which is used to press against the tread pattern on the upper surface of the tire.

[0041] The tire buckle 5, fitted onto one end of the column 2, consists of two fixed edges 51 connected at the bottom. Each fixed edge 51 includes a vertical fixed edge 511 and an oblique fixed edge 512 forming an angle greater than 90° with the vertical fixed edge 511. The two vertical fixed edges 511 are respectively connected to the two sides of the top of the fixed hook 52. The tops of the two oblique fixed edges 512 are connected by bolts 53, and nuts 531 are installed on the bolts 53. The distance from the bolts 53 to the vertical fixed edges 511 is greater than the width of the column 2. A screw sleeve 54 is fitted onto the bolts 53, and a rubber sleeve 55 is fitted onto the screw sleeve 54 to increase the friction between the tire buckle and the column, preventing external forces from causing the lifting frame to move up and down along the column. When the tire buckle 5 is not in use, the fixing hook 52 is inverted and stored between a vertical sleeve 312 and the column 2, close to the column 2. When the tire buckle 5 is used to press against the tire, the fixing hook 52 is pulled out along the column 2 and flipped along the angle of the inclined fixing edge, so that the two inclined fixing edges and the bolts grip the column tightly, and at the same time, the top surface of the fixing hook abuts against the column. In addition, an anti-collision rubber strip 7 is affixed to the side of the vertical sleeve that contacts the tire to prevent wear.

[0042] Meanwhile, to prevent damage to the tires from collision and friction between the tires and the front cover plate 412 of the transmission structure during the lifting or lowering of the elevator, the present invention provides an anti-collision structure on the front cover plate 412. This anti-collision structure is a plastic cover attached to the front cover plate. The plastic cover provides cushioning and protection for the tires in case of impact.

[0043] In summary, the wheel-assisted lifting frame of this invention, through the cooperation of the lifting device and the transmission structure, can easily lift tires or heavy objects, and with the wheel base, it can facilitate the simple transportation of tires or heavy objects. The roller mechanism enables the lifting and forward / backward movement of the tires. By adding a geared motor, along with a drill storage box and drill mounting bracket, it can be used with multiple drill models.
