Abstract
Description
Technical Field
[0001] This utility model relates to the field of road clearing equipment technology, and in particular to an automatic tire-holding mechanism and a clearing vehicle equipped with the automatic tire-holding mechanism. Background Technology
[0002] Road clearing vehicles are essential equipment in modern transportation. When clearing vehicles, clearing vehicles need to use a tire-holding mechanism to secure the vehicle's tires and prevent them from shaking during the process.
[0003] Existing tire clamping mechanisms typically use hydraulic cylinders to directly drive clamping blocks to clamp the tires. Therefore, four sets of hydraulic cylinders are required for four tires, which is costly. At the same time, since the positions of the hydraulic cylinders and clamping blocks are relatively fixed, they cannot be flexibly adjusted for tires of different sizes or vehicle models, making clamping very inconvenient. Utility Model Content
[0004] To address the aforementioned problems, this utility model proposes an automatic tire-holding mechanism that features rapid clamping, flexible adjustment, and wide applicability, as well as a clearing vehicle equipped with the automatic tire-holding mechanism.
[0005] This utility model is achieved through the following technical solution:
[0006] This utility model provides an automatic tire clamping mechanism, including a base, a tire clamping bracket, and automatic wheel clamping stops. The tire clamping bracket includes two support plates and two rods fixed to the support plates. The support plates are rotatably connected to the base. The two rods are parallel and perpendicular to the rotation direction of the support plates. Automatic wheel clamping stops are respectively provided at both ends of the two rods, and the two automatic wheel clamping stops at the same end of the two rods are arranged opposite each other. The automatic wheel clamping stops include a set of deflection plates, a clamping plate fixed between the two deflection plates, and a support rod. One end of the deflection plate is rotatably connected to the support rod, and the other end extends away from the support rod and is fixed with a support rod. The clamping plate is fixed to the end of the deflection plate near the support rod. When the support rods of the two automatic wheel clamping stops at the same end are subjected to tire pressure, they can drive the deflection plates to deflect downward, thereby driving the two clamping plates to clamp the two sides of the tire.
[0007] To facilitate the rotation of the support plate, a set of support plates is fixed on the base, and the centers of the two support plates are rotatably connected to the two support plates respectively by pins.
[0008] To facilitate the assembly of the support rods, the two support rods pass through both ends of the support plate.
[0009] In order to achieve automatic reset of the deflection plate, a tension spring is provided between one end of the deflection plate and the support rod.
[0010] To facilitate tire support, the strut is parallel to the support rod.
[0011] In order to further and more effectively clamp the tire, the clamping plate is inclined to the horizontal plane, and the top surface of the clamping plate has a row of hollow clamping blocks that can fit against the tire surface.
[0012] Since the tire spacing or size varies for different vehicle models, in order to improve the applicability of this utility model, the automatic tire clamping mechanism also includes a spacing adjustment mechanism that can adjust the position of the base. The spacing adjustment mechanism includes a support base, a sliding frame, and a hydraulic cylinder. The sliding frame is slidably connected to the support base, and the base is slidably connected to the sliding frame. The rear end of the hydraulic cylinder is rotatably connected to the support base, and the telescopic rod at the front end of the hydraulic cylinder is rotatably connected to the base. The hydraulic cylinder can drive the base to slide back and forth along the sliding frame and drive the sliding frame to slide back and forth along the support base, thereby adjusting the position of the automatic wheel clamp.
[0013] To facilitate the extension and retraction of the base and thus flexibly adjust the position of the automatic clamping wheel stop, a set of channel steel is fixed on the support base. The inner side of the channel steel has a first guide groove. There is a pair of sliding frames. The outer sides of the two sliding frames are respectively provided with first rollers that can slide along the first guide groove. The inner side of the sliding frame has a second guide groove. The outer side of the base is provided with second rollers that can slide along the second guide groove.
[0014] This utility model also provides a clearing vehicle, which is equipped with at least one set of the above-mentioned automatic tire-holding mechanism.
[0015] The beneficial effects of this utility model are: the automatic tire clamping mechanism is installed on the recovery vehicle and its position can be flexibly adjusted to meet the tire spacing requirements of different vehicle models. It has a wide range of applications. At the same time, the automatic wheel clamp does not require hydraulic cylinder drive and adopts a self-weight clamping method, which has lower manufacturing cost and better clamping effect, and can adapt to the clamping requirements of tires of different sizes.

[0019] Example 1:
[0020] like Figure 1 An automatic tire clamping mechanism is shown, comprising a base 1, a tire clamping bracket, and automatic wheel clamping stops. The tire clamping bracket includes two support plates 3 and two rods 4 fixed to the support plates 3. A set of support plates 2 is fixed on the base 1. The centers of the two support plates 3 are rotatably connected to the two support plates 2 respectively by pins. The two rods 4 are parallel and pass through both ends of the support plates 3, and are perpendicular to the rotation direction of the support plates 3. Automatic wheel clamping stops are respectively provided at both ends of the two rods 4, and the two automatic wheel clamping stops at the same end of the two rods 4 are arranged opposite each other. The automatic wheel clamping stops include a set of deflection plates 5 and a fixed... The clamping plate 6 and the support rod 7 are located between the two deflection plates 5. One end of the deflection plate 5 is rotatably connected to the support rod 4 and is provided with a tension spring. The other end extends away from the support rod 4 and is fixed with the support rod 7. The support rod 7 is parallel to the support rod 4. The clamping plate 6 is fixed to the end of the deflection plate 5 near the support rod 4. The clamping plate 6 is inclined to the horizontal plane. The top surface of the clamping plate 6 has a row of hollow clamping blocks 8 that can fit against the tire surface. When the support rod 7 of the two automatic wheel clamps at the same end is subjected to tire pressure, it can drive the deflection plate 5 to deflect downward, thereby driving the two clamping plates 6 to clamp the two sides of the tire.
[0021] In addition, the automatic tire clamping mechanism also includes a spacing adjustment mechanism that can adjust the position of the base 1. The spacing adjustment mechanism includes a support base 9, a sliding frame 12, and a hydraulic cylinder 10. A set of channel steels 11 is fixed on the support base 9. The inner side of the channel steels 11 has a first guide groove. There is a pair of sliding frames 12. The outer sides of the two sliding frames 12 are respectively provided with first rollers 13 that can slide along the first guide groove. The inner side of the sliding frame 12 has a second guide groove. The outer side of the base 1 is provided with second rollers 14 that can slide along the second guide groove. The rear end of the hydraulic cylinder 10 is rotatably connected to the support base 9. The telescopic rod at the front end of the hydraulic cylinder 10 is rotatably connected to the base 1. The hydraulic cylinder 10 can drive the base 1 to slide back and forth along the sliding frame 12 and drive the sliding frame 12 to slide back and forth along the support base 9, thereby adjusting the position of the automatic tire clamping stop.
[0022] In use, the hydraulic cylinder 10 drives the base 1 to slide back and forth along the sliding frame 12 and drives the sliding frame 12 to slide back and forth along the support seat 9, so that the automatic wheel clamp is adjusted to the corresponding position of the wheel and tire. The vehicle's tire descends and contacts the two support rods 7, pushing the support rods 7 to move downward. At this time, the two clamping plates 6 deflect inward, which can gradually press the front and rear sides of the tire together to achieve automatic tire clamping.
[0023] Example 2:
[0024] like Figure 2 As shown, this embodiment provides a clearing vehicle. The clearing vehicle 15 is equipped with two sets of the above-mentioned automatic tire clamping mechanisms 16. The two sets of automatic tire clamping mechanisms 16 can adjust their positions and clamp the four tires of the vehicle respectively.
