Description

Technical Field

[0001] This utility model relates to the field of lift technology, and in particular to a wheel fixing assembly for a lift used for drive system testing. Background Technology

[0002] Tire lifts are a common piece of equipment used in auto repair shops to lift cars for maintenance. Existing tire lifts mainly consist of three parts: a base frame, a lifting mechanism, and a tire clamping device. The tire clamps of the tire clamping device need to rub against the rubber sidewall of the tire frequently. The anti-slip pads on the inside of the clamps are deformed under pressure over a long period of time, which eventually leads to wear on the inside of the clamps and a decrease in grip strength. This means that if the anti-slip pads are damaged during subsequent use, they may scratch the tires, thus requiring frequent replacement of the anti-slip pads.

[0003] However, in practice, it has been found that the wear area of ​​the anti-slip mat is usually concentrated in the part that is in direct contact with the tire or subjected to high-frequency mechanical motion, while the rest of the anti-slip mat is basically undamaged. Moreover, the wear area often accounts for only a small part of the total area of ​​the anti-slip mat. As a result, the non-wear area of ​​the anti-slip mat cannot be effectively utilized and is discarded, which easily leads to waste. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a wheel fixing component for a lift for drive system testing, so as to solve the technical problem that the anti-slip pads of the existing lift tire clamps are easily worn and need to be replaced frequently.

[0005] To achieve the above objectives, this utility model provides a wheel fixing assembly for a lift used for drive system testing, comprising:

[0006] Two opposing tire clamps, each having a bearing surface for supporting a tire;

[0007] A non-slip pad that is detachably disposed on the bearing surface and used to isolate the tire clamp from the tire;

[0008] An adjustment mechanism connected to the lifting and lowering movable end of the lifting mechanism of the hoist is used to drive at least one of the tire clamps to move relative to the other tire clamp, so as to change the contact position between the anti-slip mat and the tire by adjusting the distance between the two tire clamps.

[0009] As a preferred embodiment of this utility model, the lifting mechanism includes:

[0010] A first slider is slidably connected to the frame of the lifting machine, and a first groove adapted to the first slider is provided in the frame;

[0011] A first drive structure for driving the first slider to slide up and down along the first groove.

[0012] As a preferred embodiment of this utility model, the first driving structure includes:

[0013] One end of the first lead screw passes through the top of the frame and extends downward into the first slide groove, and the first lead screw cooperates with the first lead screw groove opened in the first slider;

[0014] A first motor is located at the top of the frame and its output shaft is fixedly connected to the other end of the first lead screw.

[0015] As a preferred embodiment of this utility model, the adjustment mechanism includes:

[0016] A connecting frame that is fixedly connected at one end to the first slider;

[0017] A second slider is fixedly connected at one end to the tire clamping claw. The second slider is slidably engaged with a second slide groove provided in the connecting frame. The second slider has two sliders to be connected to two tire clamping claws respectively.

[0018] A second drive structure for driving the two second sliders to move towards each other and away from each other in the second slide.

[0019] As a preferred embodiment of this invention, the second driving structure includes:

[0020] A second lead screw, one end of which passes through the connecting frame and extends to the second slide groove, is a bidirectional lead screw and is engaged with a second lead screw groove formed in the second slider.

[0021] A second motor is mounted on the connecting frame and its output shaft is fixedly connected to the other end of the second lead screw.

[0022] As a preferred embodiment of the present invention, the component further includes a plurality of locking blocks disposed on the side of the anti-slip pad near the tire clamp, the locking blocks engaging with the locking grooves formed on the bearing surface of the tire clamp.

[0023] As a preferred embodiment of the present invention, the component further includes a threaded rod, one end of which passes through a first threaded groove formed in the tire clamp and extends into a slot, and the clamp block has a second threaded groove adapted to the threaded rod.

[0024] As a preferred embodiment of this utility model, the card block is arranged perpendicular to the anti-slip pad.

[0025] The beneficial effects of this utility model are as follows: By adding an adjustment mechanism to the existing lifting machine structure, this utility model can drive the two tire grippers to move relative to each other, thereby adjusting the distance between them. This causes the anti-slip mat to move along with the tire grippers, changing the contact position between the tire and the anti-slip mat's bearing surface. The non-wear area of ​​the anti-slip mat is then used to continue supporting the tire, thus making full use of the anti-slip mat's bearing surface, extending its service life, reducing replacement frequency, and saving costs.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0034] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, a wheel fixing assembly for a drive system detection lift includes: two opposing tire clamps 7, each tire clamp 7 having a bearing surface for supporting a tire; an anti-slip mat 8 detachably disposed on the bearing surface and used to isolate the tire clamps 7 from the tire; and an adjustment mechanism connected to the lifting movable end of the lift mechanism, the adjustment mechanism being used to drive at least one of the tire clamps 7 to move relative to the other tire clamp 7, so as to change the contact position between the anti-slip mat 8 and the tire by adjusting the distance between the two tire clamps 7.

[0036] The above technical solution can improve the service life of the anti-slip mat 8 by adjusting the force-bearing position of the anti-slip mat 8. After the anti-slip mat 8 has been used for a period of time, the contact area between the anti-slip mat 8 and the tire will wear. At this time, by operating the adjustment mechanism, the two tire clamps 7 are driven to move relative to each other, thereby changing the distance between the two tire clamps 7. As the tire clamps 7 move, the anti-slip mat 8 will also move together, changing the contact position between the tire and the anti-slip mat 8. The non-wear area of ​​the anti-slip mat 8 will then be used to continue supporting the tire, thus making full use of the anti-slip mat 8's bearing surface and extending its service life. At the same time, by adjusting the distance between the tire clamps 7, the lifting machine's tire clamps 7 can also adapt to tires of various diameters, improving its applicability.

[0037] like Figure 1 and Figure 2As shown, in this embodiment, the lifting mechanism includes: a first slider 5 slidably connected to the frame 1 of the lifting machine, the first slider 5 serving as a lifting movable end connected to the adjustment mechanism, and a first slide groove 2 adapted to the first slider 5 being provided in the frame 1; a first driving structure for driving the first slider 5 to slide up and down along the first slide groove 2; specifically, the first driving structure includes: a first lead screw 4 with one end penetrating through the top of the frame 1 and extending downward into the first slide groove 2, the first lead screw 4 engaging with a first lead screw groove 6 provided in the first slider 5; and a first motor 3 located at the top of the frame 1 with its output shaft fixedly connected to the other end of the first lead screw 4;

[0038] The above technical solution can lift the tires. When in use, the four lifting machines are moved to the four tires on the side of the vehicle. After ensuring that the tires are just between the tire clamps 7, the first motor 3 is started to drive the first lead screw 4 to rotate. The first lead screw 4, together with the first lead screw groove 6, drives the first slider 5 to rise along the first slide groove 2 of the frame 1, thereby driving the adjustment mechanism connected to the first slider 5 and the tire clamps 7 to rise synchronously. The tire clamps 7 rise to lift the tires.

[0039] like Figure 2 and Figure 3 As shown, in this embodiment, the adjustment mechanism includes: a connecting frame 14 with one end fixedly connected to the first slider 5; a second slider 16 with one end fixedly connected to the tire clamp 7, the second slider 16 slidingly engaging with a second slide groove 15 opened in the connecting frame 14, the second slider 16 having two parts to be respectively connected to two tire clamps 7; a second drive structure for driving the two second sliders 16 to move towards each other and away from each other in the second slide groove 15; specifically, the second drive structure includes: a second lead screw 18 with one end passing through the connecting frame 14 and extending to the second slide groove 15, the second lead screw 18 being a bidirectional lead screw, the second lead screw 18 engaging with a second lead screw groove 19 opened in the second slider 16; and a second motor 17 disposed on the connecting frame 14 with its output shaft fixedly connected to the other end of the second lead screw 18;

[0040] The above technical solution can adjust the distance between the two tire grippers 7. When in use, the second motor 17 is started so that its output shaft drives the second lead screw 18 to rotate. The second lead screw 18, in conjunction with the second lead screw groove 19, drives the second slider 16 to slide in the second slide groove 15, so that the two second sliders 16 move towards each other and away from each other, thereby driving the tire grippers 7 connected to the second sliders 16 to move synchronously, thereby adjusting the distance between them.

[0041] like Figure 4 and Figure 5As shown, in this embodiment, the component also includes a plurality of locking blocks 9 disposed on the side of the anti-slip mat 8 near the tire clamp 7, the locking blocks 9 engaging with the locking grooves 10 formed on the bearing surface of the tire clamp 7; preferably, the locking blocks 9 are disposed perpendicular to the anti-slip mat 8;

[0042] The above technical solution allows for easy replacement of the anti-slip mat 8. When the anti-slip mat 8 needs to be replaced, pull the anti-slip mat 8 to disengage its locking block 9 from the slot 10 of the tire clamp 7, thereby removing the anti-slip mat 8 from the tire clamp 7. The locking block 9 can be a rectangular or cylindrical geometric structure, as long as it can meet the requirement of restricting the anti-slip mat 8 from sliding along the surface of the tire clamp 7. The anti-slip mat 8 is preferably made of rubber material. The locking block 9 and the anti-slip mat 8 are set perpendicularly, which can better absorb the force of the tire perpendicular to the anti-slip mat 8 and prevent the locking block 9 from breaking.

[0043] like Figure 4 and Figure 5 As shown, in this embodiment, the component also includes a threaded rod 11, one end of which passes through the first threaded groove 12 opened in the tire clamp 7 and extends into the slot 10. The clamp 9 is provided with a second threaded groove 13 that is adapted to the threaded rod 11.

[0044] The above technical solution can improve the connection stability between the anti-slip mat 8 and the tire clamp 7. When the clamping block 9 of the anti-slip mat 8 is inserted into the groove 10 of the tire clamp 7, one end of the threaded rod 11 is screwed into the first threaded groove 12 and passes through the second threaded groove 13 on the surface of the clamping block 9, thereby preventing the clamping block 9 from accidentally coming out of the groove 10.

[0045] Working principle: After the anti-slip mat 8 has been used for a period of time, the contact area between the anti-slip mat 8 and the tire will wear. At this time, the second motor 17 is started so that its output shaft drives the second lead screw 18 to rotate. The second lead screw 18, in conjunction with the second lead screw groove 19, drives the second slider 16 to slide in the second slide groove 15, so that the two second sliders 16 move towards each other and away from each other. This, in turn, drives the tire clamps 7 connected to the second sliders 16 to move synchronously, thereby changing the distance between the two tire clamps 7. As the tire clamps 7 move, they will also drive the anti-slip mat 8 to move together, changing the contact position between the tire and the anti-slip mat 8. The non-wear area of ​​the anti-slip mat 8 is used to continue to support the tire, thereby making full use of the anti-slip mat 8's bearing surface and extending the service life of the anti-slip mat 8. At the same time, by adjusting the distance between the tire clamps 7, the tire clamps 7 of the lifting machine can also adapt to tires of various diameters, improving the applicability range.

[0046] When the anti-slip mat 8 needs to be replaced, rotate the threaded rod 11 to disengage it from the second threaded groove 13 of the locking block 9, and pull the anti-slip mat 8 to disengage the locking block 9 from the locking groove 10 of the tire clamp 7, so that the anti-slip mat 8 can be removed from the tire clamp 7.

[0047] When installing the anti-slip mat 8, insert the locking block 9 of the anti-slip mat 8 into the locking groove 10 of the tire clamp 7, and then screw one end of the threaded rod 11 into the first threaded groove 12 and through the second threaded groove 13 on the surface of the locking block 9 in sequence, so as to prevent the locking block 9 from accidentally coming out of the locking groove 10, thus completing the installation.

[0048] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
