Description

Technical Field

[0001] This application relates to the field of automotive repair equipment technology, and more specifically, to a safe dual-column hydraulic car lift. Background Technology

[0002] A double-column hydraulic car lift is a common type of automotive repair equipment, mainly used in auto repair shops, 4S stores, and other similar locations. It consists of two columns, a crossbeam, a hydraulic system, and a control box. The hydraulic system drives the two columns to rise synchronously, lifting the car to a certain height so that repair personnel can inspect and repair parts such as the chassis and engine.

[0003] In related technologies, wire ropes are prone to breakage and wear. After the wire rope is in operation, local friction generates heat, causing temperature changes that affect the friction force and easily lead to lifting imbalance. In order to make the transmission of the dual-post hydraulic lifting electric vehicle lift smooth, for example, the patent with the prior art publication number CN204057849U provides a dual-post hydraulic lifting electric vehicle lift. This device uses a support component, a support arm component, and a power component. The support component includes a left column, a right column, and a crossbeam fixedly connected between the tops of the left column and the right column, which makes the dual-post hydraulic lifting electric vehicle lift smooth in transmission, with low motion inertia, fast response speed, large load capacity, long service life, and smooth and safe lifting. It avoids the situation where the lifting arm suddenly drops rapidly due to the wire rope breaking when using wire rope for lifting.

[0004] Although the existing technical solutions mentioned above use hydraulic drive to raise and lower the lifting arm, avoiding the situation where the lifting arm suddenly and rapidly descends when the steel wire rope breaks, the lifting arm still requires manual adjustment by the staff to adjust the support block to the corresponding lifting position of the vehicle. This increases the workload of the staff, and manually adjusting the support block is time-consuming and labor-intensive.

[0005] In view of this, we propose a safe dual-column hydraulic car lift. Utility Model Content

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] Reference Figure 1 , Figure 2 and Figure 4 This application discloses a safe dual-column hydraulic car lift, including a hydraulic slide column 1, a slider 11 slidably disposed on the inner side of the hydraulic slide column 1, and telescopic arms 2 raised and lowered disposed on the inner side of the hydraulic slide column 1. Support blocks 3 are raised and lowered on one side of each of the two telescopic arms 2. A drive assembly A4 is disposed on one side of each of the two telescopic arms 2, and the drive assembly A4 is used to drive the two telescopic arms 2 to rotate. A drive assembly B5 is disposed at the bottom of each of the two telescopic arms 2, and the two drive assemblies B5 are used to drive the two support blocks 3 to rise and fall.

[0033] When the equipment is in use, the two telescopic arms 2 are driven to rotate by the drive component A4 and to extend and retract, so that the support block 3 is aligned with the lifting position of the car. Then, the support block 3 is driven to rise by the drive component B5, so that the support block 3 directly contacts the lifting position of the car. Then, the telescopic arms 2 are hydraulically driven to rise by the hydraulic slide column 1, so that the telescopic arms 2 rise and drive the support block 3 to rise, thereby achieving the effect of lifting the car.

[0034] The hydraulic slide column 1 is an existing technical structure, which is a mechanical device that uses hydraulic principle to drive the slider 11 to reciprocate up and down, such as a hydraulic cylinder, to drive the slider 11 and its connected structure to achieve reciprocating up and down motion.

[0035] Reference Figure 1 , Figure 2 and Figure 3A mounting plate A111 is fixedly installed on one side of the slider 11. The drive assembly A4 includes two gears 41, both of which are rotatably mounted on the mounting plate A111. The tops of the two gears 41 are fixedly mounted on one side of the two telescopic arms 2 respectively. A drive column 42 is fixedly mounted on the top of one of the gears 41. The drive column 42 rotates under external force. An installation port 21 is opened on one side of each of the two telescopic arms 2. The inner sides of the two installation ports 21 are slidably mounted on the outer sides of the two support blocks 3 respectively. Each of the two drive assemblies B5 includes a threaded rod 51. The outer sides of the two threaded rods 51 are threadedly mounted on the inner sides of the two support blocks 3 respectively. The bottoms of the two threaded rods 51 are fixedly mounted on the output ends of the corresponding gearboxes 52. A hydraulic motor B53 is fixedly mounted on the bottom of each of the two telescopic arms 2. The output ends of the two hydraulic motors B53 are fixedly mounted on the input ends of the two gearboxes 52 respectively.

[0036] Driven by the drive column 42, one gear 41 is rotated, which in turn drives another gear 41 to rotate, thereby causing the two telescopic arms 2 to rotate. This causes the two telescopic arms 2 to drive the two support blocks 3 to be located at the bottom of the two lifting positions on the side of the car, thus achieving the effect of adjusting the angle of the two telescopic arms 2.

[0037] Subsequently, two hydraulic motors B53 drive two gearboxes 52 to operate, causing the two gearboxes 52 to rotate the two threaded rods 51. The two threaded rods 51 drive the two support blocks 3 to slide inside the corresponding mounting openings 21, causing the two support blocks 3 to rise until they contact the lifting position of the car, completing the adjustment effect of the two support blocks 3. Then, the hydraulic slide column 1 drives the slider 11 to rise, causing the mounting plate A111 connected to the slider 11 to rise, thereby driving the telescopic arm 2 and the support blocks 3 to rise, completing the car lifting action.

[0038] Reference Figure 1 - Figure 5 A mounting plate B112 is fixedly installed on one side of the slider 11 at the top of the mounting plate A111. The drive column 42 passes through the mounting plate B112. A worm gear 43 is fixedly installed on the top of the drive column 42. A worm 44 is meshed on the outer side of the worm gear 43. One end of the worm 44 is rotatably installed on one side of the support plate 45. The bottom of the support plate 45 is fixedly installed on the top of the mounting plate B112. The other end of the worm 44 is fixedly installed on the output end of the hydraulic motor A46. The bottom of the hydraulic motor A46 is fixedly installed on the top of the mounting plate B112. There are two hydraulic slide column 1, telescopic arm 2, support block 3, drive assembly A4 and drive assembly B5 symmetrically arranged. A control box 12 is installed on one side of one of the hydraulic slide columns 1.

[0039] The worm gear 44 is driven to rotate by the hydraulic motor A46, which in turn drives the worm wheel 43 to rotate. The worm wheel 43 then drives the drive column 42 to rotate, thereby driving the telescopic arm 2 to complete the angle adjustment. Furthermore, the meshing of the worm wheel 43 and the worm gear 44 ensures the self-locking effect of the telescopic arm 2 after adjustment, preventing the telescopic arm 2 from shifting during use.

[0040] In use, the two telescopic arms 2 are first kept in the open state, so that the car is driven to the inside of the two hydraulic sliding columns 1. Then, the corresponding two telescopic arms 2 are driven by the drive components A4 on both sides to move the corresponding two support blocks 3, so that they are aligned with the lifting positions on both sides of the car. The operator can operate the above steps through the control box 12, which is convenient for the operator to use.

[0041] In summary, when using the safety double-column hydraulic car lift disclosed in this application embodiment, the two telescopic arms 2 are initially kept in the open state, allowing the car to drive to the inner side of the two hydraulic sliding columns 1. The drive column 42 drives one gear 41 to rotate, which in turn drives another gear 41 to rotate, thereby causing the two telescopic arms 2 to rotate. This causes the two telescopic arms 2 to drive the two support blocks 3 to be located at the bottom of the two lifting positions on one side of the car, thus achieving the effect of adjusting the angle of the two telescopic arms 2.

[0042] Subsequently, two hydraulic motors B53 drive two gearboxes 52 to operate, causing the two gearboxes 52 to rotate the two threaded rods 51. The two threaded rods 51 drive the two support blocks 3 to slide inside the corresponding mounting openings 21, causing the two support blocks 3 to rise until they contact the lifting position of the car, completing the adjustment effect of the two support blocks 3. Then, the hydraulic slide column 1 drives the slider 11 to rise, causing the mounting plate A111 connected to the slider 11 to rise, thereby driving the telescopic arm 2 and the support blocks 3 to rise, completing the car lifting action.
