Description

Technical Field

[0001] The utility model belongs to the technical field of lifts, and in particular relates to a side sliding return locking structure of a lift. Background Art

[0002] Car lifts primarily control the lifting and lowering of the machine through a hydraulic pump station that drives hydraulic cylinders. They typically utilize a scissor-type or column-type structure. When a vehicle is positioned above a platform or support arm, the lift is used to lift the vehicle, enabling repair, maintenance, and inspection. Vehicle tires have a built-in inclination angle, so a four-wheel alignment requires adjustment of various tire parameters. This process is accomplished through side sliding, resulting in a certain amount of displacement, left, right, front, and back. For lifts with four-wheel alignment, the return and locking of the side slides are crucial. Therefore, the lift's side slides must not only return quickly and smoothly, but also be reliable and stable when locked to meet the requirements of vehicle maintenance.

[0003] The patent number is 202111036057.3, and the name is "Side Sliding Structure". The side sliding return structure of this patent adopts a combination structure of screws, side sliding sliders and side sliding pin shafts.

[0004] The patent number is 201620971641.6, and the name is "Side sliding return structure of large scissor lift". The side sliding return structure of the patent adopts a combination structure of fastening bolts, side stop washers, tension springs and fastening screws.

[0005] The side-slide return mechanism in the aforementioned patent lacks a locking function and requires manual locking using the fixing pins and the fixing pin insertion holes on the side slides. After the four-wheeled cart is positioned, the side slides will deviate from their initial position. Manual locking requires aligning the side slide positioning holes with those on the side slide base plate one by one (returning them to their initial positions) before inserting the fixing pins, a cumbersome operation. Furthermore, the screws on the side slides are prone to loosening after prolonged use. Utility Model Content

[0006] The utility model aims at solving the above problems and provides a side sliding return locking structure for a lift.

[0007] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme, which includes a side slide 1, a side sliding base plate 10, a return bracket 13 and a return locking drive component 12 that drives the return bracket 13. It is characterized in that a positioning sleeve 2 is provided at the lower end of the side slide 1, and the lower end of the positioning sleeve 2 passes through the opening 11 on the side sliding base plate 10 and is placed in the positioning hole 7 on the return bracket 13. The main part of the return locking drive component 12 is fixedly connected to the side sliding base plate 10.

[0008] As a preferred solution, the positioning sleeve 2, opening 11, return bracket 13 and return locking drive component 12 of the utility model are combined into two groups, which are arranged on both sides of the length direction of the side slide 1; the driving directions of the two return locking drive components 12 are opposite.

[0009] As another preferred solution, the upper end of the positioning sleeve 2 of the present invention is welded to the lower end of the side slide plate 1 .

[0010] As another preferred solution, the return locking drive component 12 of the present invention adopts a return cylinder, and the main body of the return cylinder is fixedly connected to the side sliding base plate 10 through a fastening screw 14.

[0017] The utility model has beneficial effects.

[0018] The return locking drive component 12 of the utility model drives the return bracket 13, and the return bracket 13 drives the positioning sleeve 2, which can ensure that the side slide 1 returns to the initial position quickly and conveniently, locks reliably, and better meets the requirements of use.

DETAILED DESCRIPTION

[0033] As shown in the figure, the utility model includes a side slide 1, a side sliding base plate 10, a return bracket 13 and a return locking drive component 12 that drives the return bracket 13. A positioning sleeve 2 is provided at the lower end of the side slide 1. The lower end of the positioning sleeve 2 passes through the opening 11 on the side sliding base plate 10 and is placed in the positioning hole 7 on the return bracket 13. The main part of the return locking drive component 12 is fixedly connected to the side sliding base plate 10.

[0034] The upper end of the positioning sleeve 2 is welded to the lower end of the side slide 1. The side slide 1 is a welded component (i.e., the positioning sleeve 2 is welded to the side slide 1), and a welded positioning sleeve 2 is added. The lower end of the positioning sleeve 2 is processed with a positioning platform 4 for cooperating with the return bracket 13.

[0035] The return locking drive component 12 is a return cylinder, and the main body of the return cylinder is fixedly connected to the side sliding base plate 10 through a fastening screw 14.

[0036] The outer wall of the lower end of the positioning sleeve 2 has a section 3 on both sides that is recessed toward the middle, and the upper end of the section 3 is a positioning platform 4; the section 3 at the lower end of the positioning sleeve 2 enters the positioning hole 7, and the width of the positioning platform 4 is greater than the width of the positioning hole 7.

[0037] The fixing direction of the return bracket 13 of the utility model cannot be changed, so as to avoid the disadvantages of the fastening screw 9 being loose and the return bracket 13 rotating; the return bracket 13 will not be loose and rotated. The positioning hole 7 of the bracket top plate 5 in the return bracket 13 cooperates with the cross section 3 between the positioning platform 4 of the positioning sleeve 2, and the direction will not change, and the rotation will not occur. Figure 9 As shown. Give full play to the advantages of the lift's pneumatically controlled side sliding return locking to ensure the lift's operating requirements.

[0038] The positioning sleeve 2, the opening 11, the return bracket 13 and the return locking drive component 12 are combined into two groups, which are arranged on both sides of the side slide 1 in the length direction; the driving directions of the two return locking drive components 12 are opposite.

[0039] When the return cylinders are ventilated, the cylinder rods of the return cylinders extend, and the cylinder rod of the front return cylinder pushes the bracket bent plate 6 of the front return bracket 13, while the cylinder rod of the rear return cylinder pushes the bracket bent plate 6 of the rear return bracket 13. When the front and rear return cylinders are ventilated simultaneously, the return brackets 13 at both ends move toward their respective ends, and the positioning holes 7 of the return brackets 13 cooperate with the positioning platforms 4 of the positioning sleeve 2. The return brackets 13 are linked to the side slides 1 to achieve the return action, and are finally locked. When used with conventional fixing pins 15, it is more stable and reliable.

[0040] The device has two working states:

[0041] In the first working state, the front and rear return cylinders are not ventilated, and the cylinder rods of the front and rear return cylinders are not extended. The side slide plate 1 can move forward, backward, left and right within the range limited by the opening 11. Moreover, even though the cylinder rods are not extended, the cylinder rods are always located inside the bracket bent plate 6, thus ensuring that the cylinder rods can hit the bracket bent plate 6 when extended.

[0042] In the second working state, the front and rear return cylinders are both ventilated, and the cylinder rods at both ends press against the bracket bent plates 6 at both ends, so that the side slide plate 1 cannot move.

[0043] The return bracket includes a circular bracket top plate 5, the lower end of the bracket top plate 5 is connected to the upper end of the bracket bent plate 6, and the positioning hole 7 is set in the center of the bracket top plate 5; the upper end of the fastening screw 9 passes through the bracket retaining ring 8 and is screwed into the threaded hole at the lower end of the positioning sleeve 2, and the upper end surface of the bracket retaining ring 8 is against the lower end surface of the bracket top plate 5; the inner side of the bending part of the bracket bent plate 6 cooperates with the drive output end of the drive component 12.

[0044] The positioning hole 7 is a rectangular hole, which cooperates with the cross section 3 between the positioning platforms 4 of the positioning sleeve 2 .

[0045] The bending angle of the bracket bent plate 6 is 90 degrees, the positioning hole 7 is located on the inner side of the bracket bent plate 6, and the center line of the bracket bent plate 6 coincides with the center line of the positioning hole 7.

[0046] like Figure 5 As shown, the front and rear ends of the side slide 1 are not flush; instead, slightly angled cut surfaces 16 are formed at the four corners. When the positioning sleeves 2 are moved within the opening 11, if the front and rear positioning sleeves 2 of the side slide 1 are displaced in opposite directions, the side slide 1 will swing at a certain angle, allowing the tire to be moved for ease of use. Furthermore, the circular support top plate 5 of the return bracket 13 prevents it from falling out (the diameter of the circular support top plate 5 is greater than the width of the opening 11).

[0047] The opening 11 is a rectangular opening, and the length direction of the opening 11 is consistent with the width direction of the sideslip bottom plate 10 .

[0048] The length of the opening 11 is 116 mm, and the width of the opening 11 is 66 mm.

[0049] When pushing the car horizontally, the side slide 1 has a range of movement of 100mm. When pushing the car vertically, the side slide 1 can move forward 10mm and backward 40mm. Figure 10 As shown, the length of the opening 11 is 116 mm, the width of the opening 11 is 66 mm, the diameter of the positioning sleeve 2 is 16 mm, and the positioning sleeve 2 is displaced within the range of the opening 11. The position shown in the figure is the initial position. The left and right directions have a displacement range of 50 mm respectively, the front has a displacement range of 10 mm, and the rear has a displacement range of 40 mm.

[0050] It can be understood that the above specific description of the present invention is only used to illustrate the present invention and is not limited to the technical solutions described in the embodiments of the present invention. Ordinary technicians in this field should understand that the present invention can still be modified or replaced by equivalents to achieve the same technical effects; as long as the use requirements are met, they are within the scope of protection of the present invention.
