Description

Technical Field

[0001] This utility model relates to the field of vehicle spare tire storage devices. More specifically, this utility model relates to a vehicle-mounted lifting spare tire rack device. Background Technology

[0002] With the rapid development of oil drilling and production equipment, many oil drilling and production equipment adopts a vehicle-mounted structure, which can be easily moved and relocated to the well site; among them, spare tires are an indispensable part of oil equipment transport vehicles. Tire wear is inevitable during vehicle operation, therefore vehicles are equipped with spare tires and spare tire racks. For oil equipment vehicles and special vehicles with high chassis, due to limited chassis space, spare tire racks are generally placed under the vehicle chassis or fixed on the chassis platform. The spare tire rack is high off the ground and cannot be moved horizontally, making installation and fixation inconvenient. In existing technology, due to cost constraints, spare tire racks mostly use wire rope coils for lifting and lowering, resulting in low efficiency in unfolding and closing the spare tire rack. Therefore, changing a spare tire takes a long time, requiring personnel to manually flip the spare tire, which is extremely inconvenient. Utility Model Content

[0003] One object of this invention is to solve at least the problems described above and to provide at least the advantages that will be explained later.

[0004] To achieve these objectives and other advantages according to the present invention, a vehicle-mounted lifting spare tire rack device is provided, mounted on a vehicle chassis, comprising: The spare tire frame is a U-shaped frame structure with an opening facing one side, so that the spare tire can enter the interior from the opening side of the spare tire frame; spare tire stops are provided on both sides of the bottom of the spare tire frame. A base is fixedly mounted on the bottom of the spare tire frame; the base is detachably connected to the vehicle chassis. The flip-up frame is a U-shaped rod with its opening facing downwards. The flip-up frame is located on the opening side of the spare tire frame. The bottom of the flip-up frame is hinged to the spare tire frame, and its top is detachably connected to the spare tire. Two sets of hydraulic cylinders are respectively installed on both sides of the tilting frame; one end of the hydraulic cylinder is hinged to the upper middle part of the spare tire frame, and the other end is hinged to the lower middle part of the tilting frame.

[0005] Preferably, it also includes a strapping strap, and a hook is provided at the top center of the flipping frame. The strapping strap is tied to the spare tire and then hung on the hook.

[0006] Preferably, the spare tire frame includes a connecting rod and two sets of symmetrically arranged side frames. The side frames include a long diagonal rod, a short diagonal rod, and a crossbar. The long diagonal rod and the short diagonal rod are connected in an I-shape.

[0010] This utility model has at least the following beneficial effects: The vehicle-mounted lifting spare tire rack device provided by this utility model uses a hydraulic cylinder to drive the tilting frame to tilt, thereby raising and lowering the spare tire. This allows for quick installation and removal of the spare tire without the need for manual tilting, effectively reducing labor intensity. Furthermore, the spare tire will not interfere with the chassis during the lifting process, saving chassis space.

[0011] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

Detailed Implementation

[0013] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0014] It should be noted that, unless otherwise specified, the experimental methods described in the following embodiments are all conventional methods, and the reagents and materials described are all commercially available unless otherwise specified. In the description of this utility model, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They 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. Therefore, they should not be construed as limitations on this utility model.

[0015] like Figure 1 and Figure 2 As shown, this utility model provides a vehicle-mounted lifting spare tire rack device, which is installed on the vehicle chassis and includes: The spare tire frame 1 is a U-shaped frame structure with an opening facing one side, so that the spare tire 5 can enter its interior from the opening side of the spare tire frame 1; spare tire retaining bars 6 are provided on both sides of the bottom of the spare tire frame 1. The base is fixedly installed at the bottom of the spare tire frame 1; the base is detachably connected to the vehicle chassis. The flipping frame 3 is a U-shaped rod with its opening facing downwards. The flipping frame 3 is located on the opening side of the spare tire frame 1. The bottom of the flipping frame 3 is hinged to the spare tire frame 1, and its top is detachably connected to the spare tire 5. Two sets of hydraulic cylinders 8 are respectively installed on both sides of the tilting frame 3; one end of the hydraulic cylinder 8 is hinged to the upper middle part of the spare tire frame 1, and the other end is hinged to the lower middle part of the tilting frame 3.

[0016] In this technical solution, the spare tire frame 1 is the main structure for accommodating the spare tire 5 and is fixed to the vehicle chassis via the base. The tilting frame 3 rotates relative to its hinge point with the spare tire frame 1 under the action of two sets of hydraulic cylinders 8. When the hydraulic cylinders 8 retract to their shortest stroke, the angle between the tilting frame 3 and the spare tire frame 1 is at its minimum. At this time, the spare tire 5 is located within the spare tire frame 1 and is limited by the spare tire stop levers 6 on both sides to prevent the spare tire 5 from rolling. When the hydraulic cylinders 8 extend, the tilting frame 3 begins to rotate, simultaneously causing the spare tire 5 to slowly move away from the spare tire frame 1 and the vehicle chassis; see reference. Figure 2When the tilting frame 3 rotates to a horizontal position, the spare tire 5 moves to or near the ground. The spare tire 5 can then be separated from the tilting frame 3 for use. The vehicle-mounted lifting spare tire rack device uses the hydraulic cylinder 8 to tilt the tilting frame 3, thus raising and lowering the spare tire 5. This allows for quick installation and removal of the spare tire 5 without manual operation, effectively reducing labor intensity. Furthermore, the spare tire 5 does not interfere with the chassis during the lifting process, saving chassis space.

[0017] In another technical solution, the detachment and connection between the flipping frame 3 and the spare tire 5 are achieved through a cable tie 10. A hook 4 is provided at the top center of the flipping frame 3, and the cable tie 10 is attached to the spare tire 5 and then hung on the hook 4. The cable tie 10 and the hook 4 enable a flexible connection between the spare tire 5 and the flipping frame 3, which is convenient to install and remove, easy to obtain, has low replacement costs, and can be completed without tools. The cable tie 10 can be a conventional rubber belt. The hook 4 can be directly welded to the top center of the flipping frame 3. The hook 4 includes a U-shaped hook body and a limiting plate. One side of the hook body is fixedly connected to the top center of the flipping frame 3, and the limiting plate is fixedly disposed on the top of the hook body, partially closing the top opening of the hook body. This allows the cable tie 10 to enter the hook body from the gap between the limiting plate and the hook body, and prevents it from automatically detaching from this gap without external force.

[0018] In another technical solution, the spare tire frame 1 includes a connecting rod 12 and two sets of symmetrically arranged side frames. Each side frame includes a long diagonal rod 13, a short diagonal rod 11, and a crossbar 14. The long diagonal rod 13 and the short diagonal rod 11 are connected in an I-shape, and the crossbar 14 is fixedly installed at the bottom of the long diagonal rod 13 and the short diagonal rod 11. Both ends of the connecting rod 12 are fixedly connected to the tops of the two long diagonal rods 13. The length of the connecting rod 12 is determined by the thickness of the spare tire 5. The connecting rod 12 connects the side frames on both sides to form a U-shaped frame structure, which together forms a structure that can accommodate and protect the spare tire 5. The connecting rod 12 limits the position of the spare tire 5 from one side. Both the connecting rod 12 and the side frames are made of rectangular tubing, and both the spare tire frame 1 and the tilting frame 3 are made of high-strength structural steel. Both ends of the crossbar 14 are sealed with end plates.

[0019] Furthermore, a first ear plate 2 is provided on the upper middle part of the long diagonal rod 13, and a second ear plate 31 is provided on the lower middle part of the tilting frame 3. The two ends of the hydraulic cylinder 8 are respectively hinged to the first ear plate 2 and the second ear plate 31 by pins. The bottom sides of the tilting frame 3 are also hinged to the bottom of the two long diagonal rods 13 by pins, and the pins are inserted into the corresponding hinge holes and fixed by pins.

[0020] In another technical solution, the base includes four legs 9, and two legs 8 are symmetrically arranged at the bottom of the two crossbars 14 respectively; an L-shaped connecting plate 7 is provided on one side of each leg 8, and threaded holes are formed on the horizontal part of the connecting plate 7. After the spare tire frame 1 is placed in the corresponding position on the vehicle chassis, the connecting plate is fixed to the vehicle chassis with bolts. A threaded plate can be fixed on the vehicle chassis at the installation position of the spare tire frame 1, and the threaded plate has threaded holes that mate with the connecting plate 7. The bolted connection facilitates the replacement of the spare tire 5 in the later conversion of the continuous tubing vehicle.

[0021] In another technical solution, the distance between the two spare tire stop levers 6 is less than the diameter of the spare tire 5. The contact surface between the spare tire stop lever 6 and the spare tire 5 is set as an inclined surface or an arc surface, so that the spare tire 5 can slide into or out of the spare tire frame 1 along the inclined surface or arc surface, avoiding jamming. Furthermore, the spare tire stop lever 6 closest to the flipping frame 3 is rotatably connected to the spare tire frame 1, while the other spare tire stop lever is fixedly connected to the spare tire frame 1. When the flipping frame 3 drives the spare tire 5 to slide outward, the weight of the spare tire 5 will cause the outer spare tire stop lever 6 to flip outward so that the inclined surface or arc surface faces outward, without interfering with the spare tire 5. When installing the spare tire into the spare tire frame 1, the flipping frame 3 drives the spare tire 5 to move inward, and the spare tire 5 moves to contact the inclined surface or arc surface, further causing the outer spare tire stop lever 6 to flip inward. At this time, without the action of external force, the spare tire lever 6 on the outside will not flip due to the weight of the spare tire 5, thereby limiting the spare tire 5.

[0022] The use of the vehicle-mounted lifting spare tire rack device specifically includes the following two processes: Spare tire removal: On-site personnel operate the control valve of the hydraulic cylinder 8 to extend the hydraulic cylinder 8 and drive the tilting frame 3 to tilt downwards, slowly lowering the spare tire 8; when the spare tire 5 touches the ground, stop operating the control valve; then the on-site personnel manually untie the rubber belt 10 tied to the hook 4, and roll the spare tire 5 to the tire replacement position; operate the control valve of the hydraulic cylinder 8 to retract the hydraulic cylinder 8 and drive the tilting frame 3 to tilt upwards to return to its original position.

[0023] Spare tire installation: On-site personnel operate the control valve of the hydraulic cylinder 8 to extend the hydraulic cylinder 8 and drive the tilting frame 3 to tilt downwards to a suitable position; then, the spare tire 5 is placed directly below the tilting frame 3 and tied with the rubber belt 10, and then hung on the hook 4; the on-site personnel operate the control valve to retract the hydraulic cylinder 8 and drive the tilting frame 3 to tilt upwards, slowly lifting the spare tire 5 until it falls between the two spare tire stops 6, and then stop operating the control valve to complete the installation of the spare tire 5.

They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made.
