Description

Technical Field

[0001] This invention relates to the field of vehicle technology, specifically a device for a small-range displacement obstacle vehicle. Background Technology

[0002] Most existing rescue and clearing vehicles are flatbed structures. When towing, auxiliary wheels and hydraulic winches are needed to pull the obstacle vehicle onto the flatbed clearing vehicle. Usually, two or four auxiliary wheels are used. When using the auxiliary wheels to lift the tires of the obstacle vehicle, the auxiliary wheels need to be manually operated and a large torque needs to be applied to complete the task. In addition, each auxiliary wheel weighs about 50kg, which means that the work of lifting the obstacle vehicle with the auxiliary wheels is usually done by men with greater strength.

[0003] In addition, the process of using a winch to tow an obstacle vehicle requires sufficient open space around the obstacle vehicle.

[0004] Furthermore, the current shortage of parking spaces in the community, along with issues such as haphazard parking, obstruction of fire lanes, and ongoing neighborhood disputes, makes cleanup and relocation difficult.

[0005] Application No. 201610083501.X provides a forklift and wrecker vehicle, which consists of three parts: a base part, a wrecker function part, and common components; the base part is a truck forklift, the wrecker function part is wrecker-type parts, and the common components are fork carriages; the truck forklift has the function of a forklift, but adds the wrecker function, realizing multiple uses of one vehicle.

[0006] Authorization Announcement No. CN112590650 B This invention proposes a fully foldable trailer device and a recovery vehicle, which can solve the problems of existing lifting operation mechanisms having large space requirements and complex structures.

[0007] Authorization Announcement No. CN 213619522U: A foldable tire-holding device for a tow truck, which has a short working time and a high degree of automation, is conducive to improving work efficiency.

[0008] CN 215552815U discloses a clearing and transport vehicle, including a clamping and lifting assembly and a steering assembly. The steering assembly is located on the right side of the clamping and lifting assembly. The clamping and lifting assembly includes an inclined support connecting rod, a longitudinal connecting rod, a front tire clamping lifter, a first connecting cylinder, a connecting column, a rear tire clamping lifter, and a second connecting cylinder. The left end of the connecting column is connected to the rear tire clamping lifter. If the front tire is damaged, push the clearing vehicle to the clearing equipment and align it with the front tire. Then, open the clamps to cover the tire, adjust the width according to the gap, and press the start button to lift the clearing equipment for transport. If the rear tire is damaged, push the clearing vehicle to the clearing equipment and align it with the front tire. Then, open the clamps to cover the tire, adjust the width according to the gap, press the start button to lift the clearing equipment, and then install the rear tire lifting clamp with a manual hydraulic lifter to raise the tire off the ground for transport.

[0009] The aforementioned patent documents fail to address the issue of limited space around the obstacle vehicle, which prevents it from being moved, and also increase the physical labor intensity for workers. Summary of the Invention

[0010] In order to solve the problem of being unable to move an obstacle vehicle due to limited space around it, and to reduce the physical labor intensity of workers, this invention proposes a device for moving obstacle vehicles within a small range.

[0011] Therefore, the technical solution of the present invention is a device for a small-range displacement obstacle vehicle, including a lifting forklift or a pushcart, wherein the lifting forklift or pushcart has two forks, and a tow hook ring is also sleeved on the bottom pin of the rear end of the forklift; characterized in that: a connecting plate is provided between the two forks of the lifting forklift or pushcart near the front end, and the upper surface of the connecting plate is not lower than the upper surface of the two forks. A positioning pivot is provided vertically through a positioning hole at the middle position of the connecting plate. A base plate assembly is hinged above the connecting plate through the positioning pivot. The base plate assembly rotates relative to the fork arm and the connecting plate around the positioning pivot in the horizontal plane. The two outer ends of the base plate assembly are hinged with tire clamps.

[0012] The effect is: This invention utilizes the lifting system of the lifting forklift or trolley to move the two forks up and down, thereby raising and lowering the obstacle vehicle being forked, and using the movement of the lifting forklift or trolley to move the obstacle vehicle (with the brake released); while solving the problem of being unable to move the obstacle vehicle due to limited space around it, it also reduces the physical labor intensity of workers. The upper surface of the connecting plate is not lower than the upper plane of the two forks, which provides a redundancy or clearance for rotation after the base plate assembly is installed; The connecting plate not only connects the two forks of the forklift into one unit, but also provides a support and rotation fulcrum for the floor assembly, enabling the floor assembly to rotate relative to the forks and the connecting plate around the positioning axis in the horizontal plane, achieving spatial relative movement at the bottom of the obstacle vehicle. The base plate assembly extends into the bottom of the obstacle vehicle by moving back and forth through two forks. The two tire clamps, which are hinged to the two outer ends of the base plate assembly, clamp the two tires of the vehicle. Then, a lifting forklift or a pusher is used to adjust the direction and move the obstacle vehicle when space is limited.

[0013] A further improvement is that the base plate assembly consists of an upper plate, a middle space, and a lower plate, wherein the lower plate is opposite to the upper surface of the connecting plate, the middle space forms a relative movable space, and the upper plate forms the upper surface of the base plate assembly.

[0014] The effect is that the arrangement of the upper plate, middle space and lower plate of the base plate assembly not only helps to reduce weight, but also facilitates processing. The middle space forms a relatively large space for movement, giving the tire clamp hinged at its outer end a larger space for movement, which is conducive to the back and forth movement of the tire clamp.

[0015] A further improvement is that a limiting baffle is provided in the middle space of the base plate assembly corresponding to the extreme position of the tire clamp.

[0016] The effect is that the limit baffle provides a safe range for the tire clamp, preventing it from getting stuck.

[0017] A further improvement is that the tire clamp has a C-shaped structure, and when the tire is being held, the openings of the two tire clamps face outwards. The two arms of the tire clamp are a short arm and a long arm, with the short arm located at the far end and the long arm located at the near end.

[0018] The effect is that the C-shaped tire clamp can lift the tire by utilizing its gaps, and then raise it to form a holding structure to ensure its stability; the purpose of setting up the short arm and the long arm is simply to lift the tire.

[0019] A further improvement is that an adjusting sleeve is provided on the short arm of the tire clamp, and the adjusting sleeve and the support arm are adjusted and fixed by a pin; a support plate is also provided on the inner end of the support arm.

[0020] The effect is that the movement of the support arm within the adjusting sleeve is adjusted and fixed by a pin to accommodate tires of different diameters, ensuring that obstacle vehicles with different tire diameters can be lifted.

[0021] A further improvement is that a tension spring is provided between the outer side of the short arm of the tire clamp and the front side of the base plate assembly, so that the two tire clamps are in the same direction as the two arms of the forklift in their natural state.

[0022] The effect is that the tension springs ensure that the two tire clamps are aligned with the forklift arms in their natural state, preventing the tire clamps from shifting direction after gripping the tire.

[0023] A further improvement is that: the inner sides of the two forks of the lifting forklift or trolley are provided with sliding grooves facing each other, the openings of the sliding grooves are facing each other, a limiting hole one is provided on the sliding groove, a limiting pin passes through the limiting hole one, the sliding groove is equipped with a sliding plate, and a limiting hole two is provided on the sliding plate corresponding to the limiting pin, the limiting pin passes through the limiting hole one and the limiting hole two in sequence from top to bottom, and the two opposing sliding plates are connected by a connecting plate. The upper surface of the connecting plate is not lower than the upper surface of the fork arm. A positioning pivot is vertically provided in the middle of the connecting plate. A base plate assembly is hinged above the connecting plate through the positioning pivot. The base plate assembly rotates relative to the fork arm and the connecting plate around the positioning pivot in the horizontal plane. The base plate assembly is a three-section structure, wherein the middle section and the two side sections are connected as one piece by hinges; The outer ends of both sides of the base plate assembly are hinged with tire clamps.

[0024] The effect is: In this technical solution, the chute is equipped with a sliding plate, which in turn drives the connecting plate and the upper part to move back and forth to adjust its center of gravity, so as to facilitate the stability of the center of gravity of the obstacle vehicle during forward or backward movement or turning; and it can be removed at any time without affecting the operation of the lifting forklift or trolley. The base plate assembly is a three-section structure, in which the middle section and the two side sections are connected as one piece by hinges; the three-section hinge structure is designed so that the hinged tire clamps can be flipped upwards, saving transportation space.

[0025] A further improvement is that two sets of roller skates are also provided under the skateboard.

[0026] The effect is: The roller skates are designed so that the skateboard can move independently after leaving the track, forming a small car that moves relatively. Beneficial effects

[0027] This invention utilizes the principle of a lifting forklift or trolley's fork arm instead of a tractor, enabling flexible transfer and relocation of obstacle vehicles within a small area. Simultaneously, the connecting plate and upper structure allow for flexible control of the obstacle vehicle's center of gravity stability during forward, backward, or turning movements. After leaving the chute, the sliding plate can move independently, forming a relatively moving trolley. This solves the problem of limited space around the obstacle vehicle preventing its movement, while also reducing the physical labor intensity for workers. Attached Figure Description

Detailed Implementation

[0030] Example 1: As Figure 1-8 As shown.

[0031] A device for a small-range displacement obstacle vehicle includes a lifting forklift or trolley 1, wherein the lifting forklift or trolley 1 has two forks 2, and a hook ring 3 is fitted on the bottom pin at the rear end of the forklift 2. A connecting plate 4 is provided between the two forks 2 near the front end of the lifting forklift or trolley 1, and the upper surface of the connecting plate 4 is not lower than the upper surface of the two forks 2. A positioning pivot 5 is provided vertically at the middle position of the connecting plate 4 through the positioning hole 41. A base plate assembly 6 is hinged above the connecting plate 4 through the positioning pivot 5. The base plate assembly 6 rotates relative to the fork arm 2 and the connecting plate 4 around the positioning pivot 5 in the horizontal plane. The two outer ends of the base plate assembly 6 are hinged with tire clamps 7.

[0032] This invention utilizes the lifting system of the lifting forklift or trolley 1 to move the two fork arms 2 up and down, thereby raising and lowering the obstacle vehicle being forked, and using the movement of the lifting forklift or trolley 1 to move the obstacle vehicle (with the brake released); while solving the problem of being unable to move the obstacle vehicle due to limited space around it, it also reduces the physical labor intensity of workers. The upper surface of the connecting plate 4 is not lower than the upper plane of the two forks 2, so that there is a redundancy or clearance for the base plate assembly 6 to rotate after installation. The connecting plate 4 not only connects the two forks 2 of the lifting forklift or trolley 1 into one unit, but also provides a support and rotation fulcrum for the base plate assembly 6, so that the base plate assembly 6 can rotate relative to the forks 2 and the connecting plate 4 around the positioning pivot 5 in the horizontal plane, and realize spatial relative movement at the bottom of the obstacle vehicle. The base plate assembly 6 extends into the bottom of the obstacle vehicle through the back-and-forth movement of the two forks 2. The two tire clamps 7, which are hinged to the two outer ends of the base plate assembly 6, clamp the two tires of the vehicle. Then, the lifting forklift or pusher adjusts the direction to move the obstacle vehicle when space is limited.

[0033] The base plate assembly 6 is divided into an upper plate 61, a middle space 62 and a lower plate 63. The lower plate 61 is opposite to the upper plane of the connecting plate 4, the middle space 62 forms a relative movable space, and the upper plate 61 forms the upper plane of the base plate assembly 6.

[0034] The arrangement of the upper plate 61, middle space 62 and lower plate 63 of the base plate assembly 6 not only helps to reduce weight, but also facilitates processing. The middle space 62 forms a relatively movable space, giving the tire clamp 7 hinged at its outer end a larger movable space, which is conducive to the back and forth movement of the tire clamp 7.

[0035] The middle space 62 of the base plate assembly 6 is provided with a limiting baffle 64 corresponding to the extreme position of the tire clamp 7.

[0036] The setting of the limit baffle 64 provides a safe range for the tire clamp 7, preventing it from getting stuck.

[0037] The described tire clamp 7 has a C-shaped structure. When holding the tire, the openings 71 of the two tire clamps face outward. The two arms of the tire clamp 7 are a short arm 72 and a long arm 73, with the short arm 72 located at the far end and the long arm 73 located at the near end.

[0038] The tire clamp 7 has a C-shaped structure. It can lift the tire by utilizing its gaps, and then raise it to form a holding structure to ensure its stability. The purpose of setting up the short arm 72 and the long arm 73 is simply to lift the tire.

[0039] An adjusting sleeve 74 is also provided on the short arm 72 of the said tire clamp 7. The adjusting sleeve 74 and the support arm 76 are adjusted and fixed by a pin 75. A support plate 77 is also provided on the inner end of the support arm 76.

[0040] The support arm 76 moves within the adjusting sleeve 74 and is adjusted and fixed by the pin 75 to accommodate tires of different diameters, ensuring that obstacle vehicles with different tire diameters can be lifted.

[0041] A tension spring 8 is provided between the outer side of the short arm 72 of the tire clamp 7 and the front side of the base plate assembly 6, so that the two tire clamps 7 are in the same direction as the two arms 2 of the forklift in their natural state.

[0042] The tension spring 8 is designed so that the two tire clamps 7 are in the same direction as the two arms 2 of the forklift in their natural state, ensuring that the tire clamps 7 are in the same direction as the two arms 7 of the lifting forklift or trolley 1 after they hold the tire, and do not drift in direction.

[0043] Example 2: Figure 9-13 As shown.

[0044] The forklift has two forks 2 with opposite inner sides having grooves 9 with openings facing each other. Each groove 9 has a limiting hole 91 with a limiting pin 92 passing through it. Each groove 9 is fitted with a sliding plate 93 with a limiting hole 94 corresponding to the limiting pin 92. The limiting pin 92 passes through the limiting hole 91 and the limiting hole 94 from top to bottom. The two opposite sliding plates are connected by a connecting plate 4 through the connecting plate 93. The upper surface of the connecting plate 4 is not lower than the upper surface of the fork arm. A positioning pivot 5 is vertically provided at the middle position of the connecting plate 4. A base plate assembly 6 is hinged above the connecting plate 4 through the positioning pivot 5. The base plate assembly 6 rotates relative to the fork arm 2 and the connecting plate 4 around the positioning pivot in the horizontal plane. The base plate assembly 6 is a three-section structure, wherein the middle section 65 and the two side sections 66 are connected as one piece by hinges; The outer ends of the two side sections 66 of the base plate assembly 6 are hinged with tire clamps 7.

[0045] In this technical solution, the slide 9 is equipped with a slide plate 93, which in turn drives the connecting plate 4 and the upper part to move back and forth, thereby adjusting the center of gravity of the forklift and facilitating the stability of the center of gravity during the forward or backward movement or turning of the obstacle vehicle; and it can be removed at any time without affecting the operation of the forklift.

[0046] The base plate assembly 6 has a three-section structure, in which the middle section 65 and the two side sections 66 are connected as one piece by hinges; the three-section hinge structure is designed so that the hinged tire clamp can be flipped upwards, saving transportation space.

[0047] There are two sets of roller skates 10 below the skateboard 9.

[0048] The roller skating assembly 10 is designed so that the skateboard 93 can move independently after leaving the chute 9, forming a small car with relative motion.

[0049] This invention uses a lifting forklift or trolley 1 and a tire clamp 7. It does not require additional complex parts or operations. Simply push the vehicle to be moved up, and the tires will automatically clamp using the vehicle's own weight and mechanical structure. With the lifting forklift or trolley 1, one person can move the vehicle. Applications: One unit in residential communities can quickly clear illegally parked vehicles; one unit in parking lots can immediately clear congested traffic; one unit at accident scenes can greatly improve rescue efficiency. Moreover, the invention itself is a transport tool, making it multi-functional without adding extra burden.
