[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example 1

[0031] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a tire control device for mining dump trucks. Through the designed support mechanism 200 and operating mechanism 300, the tires of the truck can be lifted and separated from the ground, thereby facilitating the towing and transfer of a disabled truck parked on the roadside.

[0032] Specifically, it includes a docking plate 100, a docking rod 101 slidably inserted into the docking plate 100, multiple insertion holes 102 adapted to the docking rod 101 on the outer end of the wheel hub of the mining dump truck, and a docking groove 103 on its outer end. A docking post 104 adapted to the docking groove 103 is fixed on the docking plate 100. A limiting groove 105 is opened at the outer edge of the docking plate 100, and a sliding seat 106 is slidably installed on the outer side of the limiting groove 105. It also includes two support mechanisms 200 fixed on the outer side of the sliding seat 106. The support mechanisms 200 are used to lift the mining dump truck, and an operating mechanism 300 for the support mechanisms 200 to extend is installed on the outer side of the sliding seat 106.

[0033] It should be noted that in this solution, the docking plate 100 and the docking rod 101 are connected by insertion, and the docking rod 101 and the docking post 104 are designed to be inserted into the insertion hole 102 and the docking groove 103. Then, the docking plate 100 is fixed and limited by the threaded nut sleeve on the outside of the docking rod 101. After that, the personnel rotate the sliding seat 106 on the outside of the limiting groove 105 to adjust the two support mechanisms 200. With the adjustment of the operating mechanism 300, the support mechanism 200 can lift the vehicle tire, which facilitates the towing and transfer of the disabled vehicle.

[0034] It should be noted that: (referring to...) Figures 3-5 Two support mechanisms 200 are fixed at the bottom ends of the sliding seat 106 respectively. The support mechanism 200 includes an oil tank 201 fixed on the outside of the sliding seat 106. An outer pipe 202 is fixed inside the oil tank 201, and an inner rod 203 is slidably sleeved inside the outer pipe 202. An abutment 204 that contacts the ground is fixed at the outer end of the inner rod 203. An oil outlet pipe 205 is fixedly connected to one end of the oil tank 201 near the abutment 204, and an oil inlet pipe 206 is fixedly connected to the other end. One-way valves 207 facing opposite directions are installed at the outer ends of the oil outlet pipe 205 and the oil inlet pipe 206, and are connected to the operating mechanism 300 through the one-way valves 207. The oil outlet pipe 205 injects oil into the operating mechanism 300 through the one-way valves 207, and the other one-way valve 207 can inject the oil in the operating mechanism 300 into the oil inlet pipe 206. An oil draining device 208 is installed on the top of the oil tank 201.

[0035] Among them, the oil draining component 208 includes an oil draining rod 208a and a threaded cylinder 208b fixed on the oil storage tank 201. The oil draining rod 208a is threadedly inserted into the threaded cylinder 208b, and an oil outlet hole is opened on the outer tube 202. One end of the oil draining rod 208a is threadedly connected to the oil outlet hole, and a rotating cap 208c is fixed to the other end.

[0036] Meanwhile, the abutting component 204 includes a rotating rod 204a fixed to the outer end of the inner rod 203, and abutting wheels 204b are fixed to both ends of the rotating rod 204a;

[0037] The principle behind the extension and lifting mechanism 200 is as follows: (Refer to...) Figure 3 First, the operating mechanism 300 circulates and drains oil through the two one-way valves 207. The oil between the oil tank 201 and the outer pipe 202 is drawn into the operating mechanism 300 through the oil outlet pipe 205 and the one-way valve 207. Then, the operating mechanism 300 discharges the drawn oil through the one-way valve 207 into the oil inlet pipe 206 and into the outer pipe 202, causing the inner rod 203 to move outward. This causes the abutting wheel 204b in the abutting part 204 to contact and abut against the ground. With the extension of the inner rod 203, it supports the wheel. By installing docking plates 100 on the outside of multiple wheels of the disabled vehicle and opening the internal support mechanisms 200 of each, the disabled vehicle can be lifted. Through the abutting wheel 204b, it can be transported over a short distance, reducing road blockage and affecting the driving of other vehicles.

[0038] It is worth noting that after the vehicle is successfully transported and transferred, the personnel rotate the rotating cap 208c, causing the outer end of the drain rod 208a to disengage from the oil outlet on the outer tube 202. When the inner rod 203 is retracted under force, the oil in the outer tube 202 enters the cavity between the oil tank 201 and the outer tube 202 through the oil outlet, which facilitates the extension of the inner rod 203 next time.

[0039] Meanwhile, in this plan, refer to Figure 8 The one-way valve 207 includes a valve tube 207a. The inner diameter of the openings at both ends of the valve tube 207a is smaller than the inner diameter of the middle part. The outer ends of the valve tubes 207a in the two one-way valves 207 are respectively connected to the outer ends of the oil inlet pipe 206 and the oil outlet pipe 205. The valve tube 207a is fixed to the operating mechanism 300. A sealing ball 207b is provided inside the valve tube 207a. The sealing ball 207b abuts against one end of the valve tube 207a. The other end of the sealing ball 207b is fixed with a compression spring 207c that abuts against the inside of the valve tube 207a.

[0040] It should be noted that: the oil in the oil outlet pipe 205 squeezes the sealing ball 207b, causing the sealing ball 207b to detach from one end opening of the valve pipe 207a. After the oil enters the valve pipe 207a, it enters the operating mechanism 300. When the operating mechanism 300 discharges the oil, it will cause the sealing ball 207b to push one end opening, thus sealing the valve pipe 207a. At the same time, it will cause the sealing ball 207b in the other one-way valve 207 to detach from one end opening, injecting oil into the oil inlet pipe 206, thus injecting oil into the outer pipe 202 and pushing out the inner rod 203.

[0041] The maximum outer diameter of the sealing ball 207b is smaller than the inner diameter of the middle part of the valve tube 207a, so that after the sealing ball 207b is separated from one end opening, the oil can pass smoothly through the valve tube 207a. In addition, in order to improve the sealing performance of the sealing ball 207b against the one end opening, a chamfer is provided at the opening at one end of the valve tube 207a to fit against the outer wall of the sealing ball 207b. Example 2

[0042] Reference Figures 4-8 This is the second embodiment of the present invention. This embodiment provides a supplementary description of the first embodiment, which differs from the first embodiment in that it describes one implementation of the operating mechanism 300.

[0043] Specifically, the operating mechanism 300 includes an operating ring frame 301 fixed to the outside of the sliding seat 106. A rotating column 302 is rotatably mounted inside the operating ring frame 301 via a bearing. An adjusting component 303 is mounted on the outside of the rotating column 302. Two sealing plates 304 are fixed inside the operating ring frame 301, and the outer ends of the sealing plates 304 are in contact with the outside of the rotating column 302. Two piston plates 305 are fixed on the outside of the rotating column 302. Two one-way valves 207 in the support mechanism 200 are fixedly connected to the outer wall of the operating ring frame 301 and are installed between one of the sealing plates 304 and the piston plate 305.

[0044] The adjustment assembly 303 includes a crank 303a and a half gear 303b fixed to the outer end of the rotating column 302. An adjustment rod 303c is installed at the bottom of the operating ring frame 301 through a bearing seat. An adjustment gear 303d that meshes with the half gear 303b is fixed to the outer end of the adjustment rod 303c. A prismatic rod 303e is fixed to the outer end of the adjustment rod 303c. The crank 303a is adapted to the outer end of the prismatic rod 303e.

[0045] Operating principle of the operating mechanism 300: First, the operator inserts one end of the crank handle 303a into the prismatic rod 303e. Then, the operator cranks the crank handle 303a accordingly, causing the adjusting rod 303c and the prismatic rod 303e to rotate synchronously. This causes the adjusting gear 303d to rotate, which in turn drives the half gear 303b to rotate, and the rotating column 302 to rotate as well. This causes the piston plate 305 to move synchronously in the same direction, increasing the distance between the piston plate 305 and the sealing plate 304, thus creating negative pressure oil extraction and drawing oil from between the oil storage tank 201 and the outer pipe 202. Oil enters the operating ring frame 301 through the oil outlet pipe 205 and the one-way valve 207. Then, by reversing the direction of the operation, the half gear 303b and the rotating column 302 are reversed, and the piston plate 305 is brought close to the sealing plate 304. The oil between them is squeezed into another one-way valve 207 and the oil inlet pipe 206, and then transmitted to the outer pipe 202. This squeezes the inner rod 202, causing it to extend. After the crank handle 303a is rotated forward and backward multiple times, the inner rod 202 in the support mechanism 200 is continuously extended and contacts the ground. Finally, the wheel is lifted, achieving the wheel anti-lock effect.

[0046] It should be noted that: the outer end of the sealing plate 304 is fixed with a sealing arc plate 304a that fits against the rotating column 302, and the outer end of the piston plate 305 is fixed with an arc plate 304b that fits against the inner wall of the operating ring frame 301. The main function of the sealing arc plate 304a is to improve the sealing effect between it and the rotating column 302. At the same time, the arc plate 304b is designed to improve the tightness of the fit with the operating ring frame 301. The sealing arc plate 304a and the arc plate 304b are made of rubber. Example 3

[0047] Reference Figure 7 and Figure 8 This is the third embodiment of the present invention. This embodiment provides supplementary explanations to the other embodiments. The difference between this embodiment and the other embodiments is the optimization and improvement of the operation ring 301.

[0048] Specifically, the operating ring frame 301 is made of transparent material, and the operating ring frame 301 has an oil drain hole with a plug. There are two oil drain holes designed to be distributed at the positions of the two sealing plates 304, which can drain the oil that seeps out from the outside of the sealing plates 304.

[0049] It should be noted that the transparent operating ring frame 301 allows personnel to easily observe the oil condition inside. At the same time, the designed oil drain hole can handle the oil that seeps out from the outside of the inner sealing plate 304 of the operating ring frame 301. Personnel can directly observe the oil condition and it is also convenient for subsequent oil replenishment and replacement.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
