Description

Technical Field

[0001] This utility model relates to the field of automotive maintenance equipment technology, and in particular to a variable tire holding device for a large horizontal tire changer. Background Technology

[0002] Tire removal and installation is a common scenario in vehicle maintenance. Large-diameter tires are generally removed and installed using large horizontal tire changers. These tire changers typically use a support arm structure to support the tire holding device for clamping the tire.

[0003] The tire holding arm of a horizontal tire changer typically employs a two-section, bendable structure. This type of arm is characterized by good stability and mature technology, and is widely used. However, its structure is complex, limiting its applicability to a narrow range of tire diameters. Another type is the cantilevered support arm, where a tire clamping device is fixed to the end of the arm, upon which the tire is secured. Tire holding devices using this type of arm have a simple and compact structure. However, for handling extra-large tires, a longer support arm is required. An excessively long support arm can cause vibration during tire changer operation and carries the risk of deformation and bending. Furthermore, this type of tire changer also limits its applicability to a wider range of tire diameters. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a tire holding device for large horizontal tire changers that has a variable cantilever beam, good rigidity, and is applicable to a wide range of tire diameters.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a variable position tire holding device for a large tire changer, wherein the variable position tire holding device is fixed on the base of the tire changer via a crossbeam slide rail, the variable position tire holding device includes a cantilever beam and a cantilever beam sleeve forming a kinematic pair, and a first driving component for driving the cantilever beam sleeve to move, wherein one side of the cantilever beam is provided with a slide groove passing through the cantilever beam sleeve and a pivot shaft that can move axially relative to the cantilever beam sleeve; a support sliding column and a cross-moving connecting component fixed on the base to form a kinematic pair, and a second driving component for driving the cross-moving connecting component to move, wherein the cross-moving connecting component is provided with a pivot shaft sliding hole that is slidably connected to the pivot shaft, and when the cross-moving connecting component moves up and down in a linear motion, it drives the cantilever beam to rotate by a corresponding angle.

[0006] In a preferred embodiment of the variable tire holding device of this utility model, it further includes a synchronous rotational connecting component that vertically and fixedly connects the cantilever beam and the crossbeam slide. When the cantilever beam rotates, the synchronous rotational connecting component drives the crossbeam slide to rotate synchronously.

[0007] In a preferred embodiment of the variable tire holding device of this utility model, the cantilever beam rotates upward from the surface of the base by an angle of º25º-30ºº.

[0008] In a preferred embodiment of the variable tire holding device of this utility model, the supporting sliding column is arranged perpendicularly to the base.

[0009] In a preferred embodiment of the variable-position tire retaining device of this utility model, the cross-sections of the cantilever beam, the cantilever beam sleeve, the supporting sliding column, and the cross-moving connecting component are all square.

[0010] In a preferred embodiment of the variable tire holding device of this utility model, the derailleur is a cylinder disposed in the middle of the opposite side of the cantilever beam and the cross-moving connecting component, and the slide groove is a long strip-shaped through groove in which the derailleur can slide along the length direction of the cantilever beam sliding sleeve.

[0015] This utility model of a variable-position tire retaining device has the following advantages over the prior art: it adopts a cantilever beam and a cantilever beam sliding sleeve to form a variable-position cantilever beam structure, and at the same time adopts a cross-moving connecting component to connect the supporting sliding column and the movable connecting cantilever beam. This can ensure that the cross-moving connecting component provides sufficient support force to the middle of the cantilever beam during the rising process, preventing the tire removal arm from vibrating or even bending and deforming; during the rising process of the cross-moving connecting component, the cantilever beam sliding sleeve can move freely along the cantilever beam at the same time, which can expand the diameter range of the tires to be removed and installed.

Detailed Implementation

[0023] 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 the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Please see Figure 1-5 As shown, the variable position tire holding device for a large tire changer in this embodiment includes a variable position tire clamping component 1 disposed on a crossbeam slide 3, wherein the crossbeam slide 3 is rotatably fixed on bearing seats on both sides of the base 4.

[0025] In this embodiment, the cantilever beam 11 slides within the cantilever beam sleeve 12, forming a kinematic pair capable of axial relative movement. One end of the first driving component 13 is connected to the cantilever beam sleeve 12, and the other end is connected to the synchronous rotation connecting component 18 to drive the cantilever beam sleeve 12 to move. Preferably, both the cantilever beam 11 and the cantilever beam sleeve 12 have a square cross-sectional shape. A pivot 111 is provided on the side of the cantilever beam 11 opposite to the cross-moving connecting component 16. The pivot 111 can be a cylinder located in the middle of the cantilever beam 11. A groove 121 is provided on the same side of the cantilever beam sleeve 12 as the cantilever beam 11. The groove 121 is an elongated through-slot along the length of the cantilever beam sleeve 12, and the pivot 111 can slide within the elongated through-slot. The supporting sliding column 15 is fixed on the base 4, and the cross-moving connecting component 16 is fitted outside the supporting sliding column 15 to form a kinematic pair with it. The second driving component 17 connects to and drives the cross-moving connecting component 16 to move. In a preferred embodiment, the supporting sliding column 15 is perpendicular to the base 4, and both the supporting sliding column 15 and the cross-moving connecting component 16 can have a square cross-section. A shift fork 162 is provided on the side of the cross-moving connecting component 16 opposite to the cantilever beam sliding sleeve 12, and a shift shaft sliding hole 161 is provided on the shift fork 162. The shift shaft sliding hole 161 can be a long strip-shaped through hole with a width of 140mm-160mm.

[0026] In this embodiment, the pivot 111 of the cantilever beam 11 passes through the groove 121 of the cantilever beam sliding sleeve 12 and is slidably connected to the pivot sliding hole 161 of the cross-moving connecting component 16 on the opposite side. When the cross-moving connecting component 16 moves vertically, it can drive the cantilever beam 11 to rotate by a corresponding angle through the pivot sliding hole 161 and the pivot 111. The rotation angle is approximately 25º-30º upward from the surface of the base 4. The synchronous rotation connecting component 18 vertically and fixedly connects the cantilever beam 11 and the crossbeam slide 3. The synchronous rotation connecting component 18 includes a first slot 181 for fixing the crossbeam slide 3 and a second slot 182 perpendicular to the first slot 181 for fixing the cantilever beam 11. When the cantilever beam 11 rotates, it drives the crossbeam slide 3 to rotate synchronously through the synchronous rotation connecting component 18.

[0027] In this embodiment, the cantilever beam 11 and the relatively movable cantilever beam sleeve 12 structure enable the cantilever beam to be extended in a variable position. The support sliding column 15 and the relatively movable cross-moving connecting component 16 structure enable the cantilever beam to change its angle with the horizontal plane. The change in the length and angle of the cantilever beam can be adapted to a wider range of tire diameter changes, i.e., it can be adapted to tires of various diameters. When the tire diameter is small, the total length of the cantilever beam and the cantilever beam sleeve can be shortened and a smaller angle can be used. When the tire diameter is large, the total length of the cantilever beam and the cantilever beam sleeve can be extended and a larger angle can be used. Thus, the change in the total length and angle of the cantilever beam and the cantilever beam sleeve allows the tire changer to change and install various tire diameter specifications. The structure employs a sliding connection between the supporting sliding column and the cross-moving connection, where the pivot of the cantilever beam passes through the groove of the cantilever beam sliding sleeve and slides through the pivot hole of the cross-moving connection component on the opposite side. The supporting sliding column provides reliable support for the cantilever beam, and the axial movement of the cantilever beam sliding sleeve will not interfere with the vertical movement of the cross-moving connection component. The angle and length of the cantilever beam can be adjusted simultaneously to ensure that the cantilever beam does not experience vibration or bend.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
