Description

Technical Field

[0001] This utility model relates to the field of road clearing equipment technology, and in particular to a modular superimposed heavy vehicle wheel auxiliary support moving mechanism. Background Technology

[0002] Road clearing vehicles are essential equipment in modern transportation. However, when encountering heavily damaged vehicles with flat tires, no tires, no rims, or no hubs, they cannot be towed away. Large cranes and flatbed trucks must be used for rescue and removal, resulting in low clearing efficiency and high costs.

[0003] Therefore, wheel support devices are now commonly used to assist tow trucks. For example, CN204775180U discloses a heavy-duty auxiliary wheel device for a tow truck, and CN210391093U discloses an auxiliary wheel device for driving a car involved in an accident. By supporting the tires of a heavy-duty accident vehicle, the tow truck can move instead of the vehicle's wheels, thereby assisting the tow truck in achieving traction.

[0004] However, due to the different sizes of the tires and wheels on the accident vehicle, or the tires possibly having detached from the rims, this type of wheel support device cannot be precisely matched to the wheels of different vehicle models. When the accident wheel is placed on this wheel support device, there will be some room for movement. Therefore, it is necessary to tie the accident wheel to the wheel support device or use a relevant locking mechanism to lock it. Otherwise, during the towing process by the tow truck, the accident wheel may fall off the wheel support device, causing danger. At the same time, because the tires of the accident wheel may have been displaced or are deflated, when the accident wheel is placed on the wheel support device, the height of the accident wheel will be lower than the height of other normal wheels, which will cause the entire vehicle to tilt to a certain extent, posing a risk of tipping over when the tow truck tows it. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a modular, stacked heavy vehicle wheel auxiliary support moving mechanism, which can handle various wheel accidents of different types of heavy vehicles, assist the clearing vehicle in clearing operations, and ensure the safety, speed, and effectiveness of clearing operations.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model provides a modular superimposed heavy vehicle wheel auxiliary support moving mechanism, including a wheel support frame, a set of wheel axles set at the front and rear ends of the wheel support frame, and a set of rollers rotatably connected to the wheel axles. The wheel support frame includes a set of side supports arranged opposite to each other. The front and rear ends of the two side supports are connected by a front fixed plate and a rear fixed plate, respectively. Several parallel support connecting rods are fixed between the two side supports, and an arc-shaped support part that can support the heavy vehicle wheel is formed between each support connecting rod.

[0008] The modular stacked heavy vehicle wheel auxiliary support moving mechanism also includes at least one modular pad that can be placed on the arc-shaped support. The bottom end of the modular pad has a lower arc-shaped support surface that can abut against the top end of each bracket connecting rod, and the top end of the modular pad has an upper arc-shaped support surface. The upper arc-shaped support surface can support the lower arc-shaped support surface of another modular pad, so as to realize the stacking of the two modular pads, or the upper arc-shaped support surface can support the heavy vehicle wheel.

[0009] To prevent the modular pad from sliding on the arc-shaped support, limiting beams are fixed at the front and rear ends of the two side supports respectively. The limiting beams have a horizontal surface that can support the end of the modular pad and a vertical surface that can prevent the modular pad from moving forward or backward.

[0010] To prevent relative sliding between modular pads, connecting plates are fixed at both ends of the modular pads, and the two connecting plates at the same end of two adjacent modular pads can be locked together by a first bolt assembly.

[0011] To prevent the accident wheel from sliding within the upper arc-shaped support surface of the modular pad, the modular stacked heavy vehicle wheel auxiliary support moving mechanism also includes a fastening sleeve that can fasten the heavy vehicle wheel to the modular pad. The top surface of the modular pad has several through holes, and both ends of the fastening sleeve are connected to the through holes through a second bolt assembly. The fastening sleeve has an arc-shaped surface that can fit against the surface of the heavy vehicle wheel.

[0012] To reduce the overall weight of the modular stacked heavy vehicle wheel auxiliary support moving mechanism and to facilitate easy stacking by operators, the modular pads are made of wood. To ensure the strength of the wooden modular pads, reinforcing plates are fixed to both ends of the modular pads.

[0013] To facilitate quick assembly and disassembly of the roller support frame and the axle, the side bracket has U-shaped holes at both ends that can be fitted onto the axle from top to bottom.

[0014] Because vibrations may occur during traction, which could cause the support frame to detach from the axle, a connecting rod is fixed at the bottom of the side support to prevent the side support from detaching from the axle. The connecting rod is located below the axle, and both ends of the connecting rod are locked to the front and rear ends of the side support by locking devices.

[0015] To facilitate traction of the modular, stacked heavy vehicle wheel auxiliary support moving mechanism, the front and rear fixed plates are fixed with pull buckles and hook plates capable of traction of the roller frame.

[0016] The beneficial effects of this utility model are as follows: This utility model uses a specially designed roller support frame and modular pads in combination, and adopts a split design, which makes it easy to move quickly and install on site. The modular pads can be stacked on the roller support frame in sequence to match the wheels of different vehicle models and their various accident conditions (including flat tires, no tires, no tires, no steel rims, no rims, etc.). The wheels can be raised according to the actual situation of the wheels and their various accident conditions, so that all the wheels of the accident vehicle are at the same height, while avoiding relative movement between the wheels and the roller support frame, thereby greatly improving the safety, speed and effectiveness of the clearing vehicle.

[0024] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. In the description of this utility model, it should be noted that the terms "upper," "lower," "left," "right," "top," "bottom," "side," "end," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0025] like Figure 1 The modular stacked heavy vehicle wheel auxiliary support moving mechanism shown includes a wheel support frame 2, a set of wheel axles 3 set at the front and rear ends of the wheel support frame 2, and a roller group 4 rotatably connected to the wheel axles 3. The wheel axles 3 include a front wheel axle and a rear wheel axle. A set of rollers is set at each end of the front wheel axle or the rear wheel axle, for a total of four rollers. That is, the wheel support frame 2 can move along the ground through the wheel axles 3 and the roller group 4.

[0026] It also includes at least one modular pad 5 that can be placed on the wheel support 2. There can be one or more modular pads 5, and multiple modular pads 5 can be stacked upwards in sequence. The wheel 1 of the accident vehicle is placed on the topmost modular pad 5 and pressed by the fastening sleeve 6.

[0027] This utility model designs the roller bracket 2, wheel axle 3, and roller assembly 4 as separate installation structures, and with the modular pad block 5, it can achieve rapid movement and rapid on-site assembly.

[0028] Specifically, in combination Figure 2-3As shown, the roller support frame includes a set of opposing side supports 201. The front and rear ends of the two side supports 201 are connected by a front fixing plate 202 and a rear fixing plate, respectively. That is, the side supports 201, the front fixing plate 202, and the rear fixing plate form a rectangular frame structure. Several parallel support connecting rods 203 are fixed between the two side supports 201. The support connecting rods 203 are perpendicular to the end face of the side supports 201. The support connecting rods 203 form an arc-shaped support part that can support the wheel of a heavy vehicle. That is, the height of the support connecting rod 203 gradually decreases from the front and rear ends of the side supports 201 towards the center, forming an arc-shaped support part that can match the wheel. The front of the side support 201... The rear ends are respectively provided with U-shaped holes 205 that can be fitted onto the wheel axle 3 from top to bottom, which can realize easy disassembly and assembly of the side bracket 201 and the wheel axle 3. Correspondingly, the bottom ends of the two side brackets 201 are respectively fixed with connecting rods 206 to prevent the side brackets 201 from falling off the wheel axle 3. The connecting rods 206 are located below the wheel axle 3. The two ends of the connecting rods 206 are respectively locked to the front and rear ends of the side brackets 201 by locking parts 207. Even if there is severe vibration, the side brackets 201 cannot be separated from the wheel axle 3 due to the blocking and limiting effect of the connecting rods 206. Moreover, the two connecting rods 206 can also increase the strength and stability of the entire roller support frame.

[0029] Meanwhile, limiting beams 204 are fixed at the front and rear ends of the two side supports 201 respectively. The two limiting beams 204 are arranged opposite to each other. The limiting beams 204 have a horizontal surface that can support the end of the modular pad and a vertical surface that can prevent the modular pad from moving forward or backward. That is, the limiting beams 204 have a stepped structure, which limits the modular pad and prevents it from moving forward or backward. Furthermore, a row of side limiting pins 208 are fixed on the inner end face of the two side supports 201 respectively, which can prevent the modular pad from moving left or right.

[0030] In addition, the front fixed plate 202 and the rear fixed plate are both fixed with pull buckles 209 and hook plates 210 that can pull the roller frame, so as to meet the traction requirements of different traction mechanisms.

[0031] Specifically, in combination Figure 4As shown, the modular pad is made of wood. Steel reinforcing plates 503 are fixed on both ends of the modular pad to prevent it from breaking under great pressure. The bottom of the modular pad has a lower arc-shaped support surface 501 that can abut against the top of each bracket connecting rod 203. The two ends of the lower arc-shaped support surface 501 are horizontal support surfaces 502. When the lower arc-shaped support surface 501 is placed on each bracket connecting rod 203, the horizontal support surface 502 is placed on the horizontal surface of the limiting beam 204. The top of the modular pad has an upper arc-shaped support surface. The upper arc-shaped support surface can support the lower arc-shaped support surface of another modular pad, so as to realize the stacking of two modular pads, or the upper arc-shaped support surface can support heavy vehicle wheels, tires, hubs, and axles.

[0032] Meanwhile, the modular pad is fixed with connecting plates 504 at both ends. The two connecting plates 504 at the same end of two adjacent modular pads can be locked together by the first bolt assembly to prevent relative movement between the two adjacent modular pads.

[0033] In addition, the top surface of the modular pad has several through holes 505. The two ends of the fastening sleeve 6 are connected to the through holes 505 by the second bolt assembly 7. The fastening sleeve 6 has an arc-shaped surface that can fit with the surface of the heavy vehicle wheel. Correspondingly, the side end surface of the modular pad has mounting holes 506 that are connected to the through holes 505. The mounting holes 506 can facilitate the second bolt assembly 7 to lock, and can also reduce the weight of the entire modular pad.

[0034] It should be noted that the height of a single modular pad can be designed according to the actual situation, and the curvature of the upper and lower arc-shaped support surfaces of the modular pad can also be designed in a variety of ways according to the actual situation. The number of modular pads stacked can be flexibly adjusted according to the vehicle type, wheel model, or severity of the accident.

[0035] The following examples will illustrate this point.

[0036] Example 1

[0037] In this embodiment, one of the tires of the accident vehicle is in a state of puncture or blowout, that is, the tire of that wheel is still on the rim, and the wheel has only a small height difference relative to the other wheels. This can be addressed by using methods such as... Figure 5 As shown in the structure, the vehicle is lifted by a jack, and the modular stacked heavy vehicle wheel auxiliary support moving mechanism of this utility model is placed under the wheel. At this time, there is no need to place modular pads. The accident wheel is supported by the connecting rods 203 of each bracket, the two limiting beams 204 limit the front and rear of the wheel, and the two rows of side limiting pins 208 limit the left and right sides of the wheel, which can support the accident wheel and achieve auxiliary traction in conjunction with the recovery vehicle.

[0038] Example 2

[0039] In this embodiment, the tire of one of the wheels of the accident vehicle has detached from the rim, therefore this wheel has a certain height difference relative to the other wheels. This can be addressed by using methods such as... Figure 6 The structure shown differs from Embodiment 1 in that a modular pad 5 is placed on the wheel support frame 2, and the wheel hub of the accident wheel is placed on the upper arc-shaped support surface of the modular pad 5. The modular pad 5 raises the wheel hub of the accident wheel so that it is at the same height as other wheels. In addition, depending on the actual situation, it is possible to choose whether to use a fastening sleeve to lock the wheel hub to the modular pad 5, which can support the accident wheel and assist in traction with the recovery vehicle.

[0040] Example 3

[0041] In this embodiment, one of the wheels of the accident vehicle has detached, leaving only the axle. Therefore, this axle has a significant height difference relative to the other wheels, which can be addressed by employing methods such as... Figure 7 The structure shown differs from embodiments 1 and 2 in that the wheel support frame 2 stacks two modular pads 5 in sequence. The two modular pads 5 further raise the axle of the accident wheel so that it is at the same height as the other wheels. In addition, depending on the actual situation, it is possible to choose whether to use a fastening sleeve 6 to lock the axle to the modular pads 5, which can support the axle of the accident wheel and assist in traction with the recovery vehicle.
