Since the vehicle is equipped with large-size and large-weight special tires, the diameter reaches several meters, and the weight reaches several hundred kilograms, the tire needs to be dismounted and transferred during replacement and maintenance. Due to the large size and complex structure of the tire body, and the limitation of the working conditions, the labor intensity of tire dismounting and transfer is large, and there is a great safety risk.

[0003] At present, the traditional tire dismounting usually adopts a tire wrench, a jack and other tools, and is assisted by a forklift or hoisting equipment to complete the operation. Such operation is not only low in efficiency, but also prone to tire rolling, instability and other situations during operation, which may cause accidents. Especially in narrow or complex terrain areas, when the tire is separated from the axle, there is a lack of effective support and guidance for the tire, which may cause the tire to suddenly fall or deviate, and also cause damage to the tire body or vehicle parts. Based on the above reasons, there is an urgent need for a special device that can realize stable tire dismounting and transfer, so as to improve the operation efficiency and ensure safety.

[0024] In order to make the technical problems, technical schemes and beneficial effects of the utility model to be solved more clear and explicit, the utility model is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0025] As shown in Figure 1 , the application provides a large mine wide-body vehicle tire dismounting and transferring device, which is particularly suitable for mine, port, large construction site and other operation scenes that need to frequently dismount and replace heavy vehicle tires. The device integrates supporting, fixing, dismounting and transferring functions in one, which can effectively improve the safety and operation efficiency of large tire dismounting.

[0026] As shown in Figure 1 and Figure 2 , the large mine wide-body vehicle tire dismounting and transferring device of the application comprises a structurally stable base 1, the lower end of the base 1 is provided with a wheel assembly 2, which preferably comprises a pair of one-way wheel groups and a pair of universal wheel groups, which not only ensures the stability of straight-line propulsion, but also facilitates flexible steering operation in a small space. A pair of vertical rods 3 are welded on the base 1 in the vertical direction, the vertical rods 3 not only serve as the installation reference of the tire fixing device 5, but also are provided with a pair of handrails 7, which are convenient for the operator to hold with both hands to improve the stability and safety during operation.

[0027] In order to effectively support and prevent the tire from falling over, a pair of fork arms 4 are symmetrically hinged on the base 1. Preferably, the fork arms 4 are rectangular pipe frame structures, which have high strength and light weight, and are beneficial to supporting large-diameter tires. A plurality of adjusting tubes 6 with different spacings are provided on the fork arms 4, and the operator can select the appropriate position of the adjusting tube 6 according to the width of the tire to realize the adaptation and support of different specifications of tires. In addition, limiters 8 are also provided on the pipe frame to provide lateral limiting during tire placement to prevent the tire from slipping or deviating.

[0028] As shown in Figure 3As shown, in order to further realize the stable fixing and dismounting assistance of the tire, a tire fixing device 5 is movably mounted between the vertical rods 3. The device includes two horizontal rods 51 distributed upward and downward, and a pair of rotatable hooks 52 is hinged to the upper horizontal rod 51, and the hooks 52 are used to abut against the far end surface of the tire, so as to realize the fixing of the longitudinal position of the tire. The lower horizontal rod 51 movably mounts an adjusting member 53, which includes a threaded rod 531, a hollow sleeve rod 532 sleeved outside the threaded rod 531, and a nut 533 threaded connected to the threaded rod 531. The operator can adjust the extension length of the sleeve rod 532 by rotating the nut 533, so that the sleeve rod 532 is stably abutted against the near end surface of the tire, realizes the clamping and fixing of the front and rear end surfaces of the tire, and prevents the tire from shaking or overturning during dismounting.

[0029] Through the above structural design, the mine large wide tire dismounting and transferring device of the present application can stably support the tire before dismounting, and realize the front and rear clamping through the fixing device, which greatly reduces the displacement risk of the tire during dismounting stress. After dismounting is completed, the operator can control the whole device to move by holding the handrails 7, and the tire is stably transferred to the designated position, avoiding the unstable factors caused by the lifting equipment, and improving the operation flexibility and safety.

[0030] In summary, the device of the present application has compact structure, simple operation, and can adapt to the dismounting requirements of large tires of different specifications, and is especially suitable for use in space-limited or complex terrain mine operation environment. By integrating the supporting, fixing, dismounting and transferring functions, the safety and efficiency of the operation are effectively improved, and the device has high popularization and application value.

[0031] The utility model has been described above in conjunction with the drawings, and obviously, the specific implementation of the utility model is not limited by the above mode. As long as various non-essential improvements are made by adopting the method concept and technical scheme of the utility model, or the concept and technical scheme of the utility model is directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
