Description

Technical Field

[0001] This invention relates to the field of hoisting equipment technology, specifically to a hoisting equipment for automotive parts. Background Technology

[0002] Lifting equipment is a type of mechanical device used to lift, move, and precisely position heavy objects. Its core functions cover vertical lifting and horizontal handling. This type of equipment has a wide range of applications and is indispensable in scenarios such as handling heavy parts in the automotive parts manufacturing industry. It is a key piece of equipment supporting industrial production.

[0003] In the traditional auto parts industry, pallet jacks are mostly used for transporting auto parts, but there is a lack of effective equipment for hoisting parts, even though there are corresponding hoisting devices that can lift auto parts.

[0004] However, existing technologies still have significant shortcomings, such as: Traditional hoisting equipment often relies on a single base or simple support frame, resulting in a small support area that cannot effectively distribute the hoisting load. Furthermore, due to the insufficient support area, the equipment itself is prone to tilting when hoisting heavy components due to excessive localized stress, which can even lead to safety accidents. Summary of the Invention

[0005] The purpose of this invention is to provide an automotive parts hoisting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An automotive parts hoisting device includes a base, on which are provided casters and guide wheels. A rotating shaft is rotatably mounted on the base, and a vertical frame is fixedly mounted on the rotating shaft. A plurality of first telescopic cylinders are rotatably mounted on the base, and the movable ends of the first telescopic cylinders are rotatably connected to the vertical frame. A lifting frame is slidably mounted on the upright frame, and a second telescopic cylinder is fixedly mounted on the upright frame. The movable end of the second telescopic cylinder is fixedly connected to the lifting frame, and a hoisting assembly is slidably mounted in the lifting frame. The hoisting assembly includes a hoisting frame slidably disposed in a lifting frame, a hoisting arm rotatably disposed on the hoisting frame, a hoisting rod slidably disposed on the hoisting arm, and a hoisting ring slidably disposed on the hoisting rod; A sprocket is rotatably mounted on the movable end of the second telescopic cylinder. A chain is wound around the sprocket. One end of the chain is fixedly mounted on the lifting frame, and the other end of the chain is fixedly mounted on the hoisting frame. The base is provided with a support component, which is linked to the rotating shaft.

[0007] Preferably, the base has a groove, the support assembly includes a rotating shaft rotatably disposed in the groove, a support arm is fixedly disposed on the rotating shaft, and the rotating shaft and the rotating shaft are driven by a first bevel gear set.

[0008] Preferably, the support assembly further includes a plurality of connecting rods rotatably mounted on the support arm, and the other end of the plurality of connecting rods is rotatably mounted with a support foot.

[0009] Preferably, a bevel gear ring is fixedly mounted on the base, a linkage rod is rotatably mounted on the support arm, and a driven bevel gear is fixedly mounted at one end of the linkage rod, the driven bevel gear meshing with the bevel gear ring for transmission; The other end of the linkage rod is driven between the shaft of one of the connecting rods via a second bevel gear set.

[0010] Preferably, a pull rod is rotatably provided on the base.

[0011] Preferably, a rotating seat is fixedly installed on the upright frame, and a handle is movably installed in the rotating seat. A positioning groove is opened on the rotating seat, and the positioning groove is located on both sides of the rotation center of the handle. A positioning shaft that cooperates with the positioning groove is provided on the handle, and a spring is sleeved on the shaft of the handle. The spring is located between the handle and the rotating seat.

[0012] Preferably, the guide wheel is rotatably mounted on the base via a wheel frame.

[0013] Preferably, a limit plate is fixedly installed on the hoisting frame, and the hoisting arm is L-shaped.

[0014] Preferably, a protective cover is fixedly installed on the base, and the protective cover is located on the outside of the first bevel gear set.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This device innovatively integrates transportation and hoisting functions. In its retracted state, it can be easily towed like a pallet jack to achieve horizontal transportation and transfer of automotive parts. In its extended state, the first telescopic cylinder drives the upright frame to stand up, switching to hoisting mode. No additional transportation equipment is required. One device meets two operational needs, greatly improving the versatility of the equipment and reducing the equipment investment cost for enterprises.

[0016] 2. The device uses a first bevel gear set to link the rotation of the upright frame with the support assembly. When the upright frame rotates around the rotation axis, it synchronously drives the rotation axis of the support assembly, causing the support arm to rotate out of the base groove. Simultaneously, during the movement of the support arm, the driven bevel gear meshes with a fixed bevel gear ring, driving the linkage rod to rotate, which in turn drives the connecting rod to unfold the support legs via the second bevel gear set. This linkage structure allows the support arm and support legs to automatically unfold, forming a support structure extending to both sides from the base as the center. This significantly increases the contact area between the equipment and the ground, disperses the lifting load, and prevents the equipment from tilting due to excessive local stress. Compared to traditional lifting equipment with a single base support, stability is greatly improved, ensuring the safety of lifting operations. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-9 The present invention provides a technical solution: This device is specifically designed for the transportation and hoisting of automotive parts. The base 1 serves as the fundamental support structure for the entire equipment, with its top and sides used to support and install all other functional components, ensuring that each component maintains a relatively stable positional relationship during operation.

[0021] At the four corners or edges of the base 1, casters 2 and guide wheels 3 are installed respectively. The guide wheels 3 are connected to the base 1 via wheel frames 24. The top of the wheel frame 24 is bolted to the bottom of the base 1, and the lower part of the wheel frame 24 has an axle hole through which the axle of the guide wheel 3 passes, allowing the guide wheel 3 to rotate freely relative to the wheel frame 24 around its own axle, guiding the direction of travel when the equipment moves. The casters 2 are directly fixed to the bottom of the base 1 via connectors and have a built-in locking mechanism. When the equipment needs to move on the ground, the locking mechanism is unlocked, allowing the casters 2 to rotate 360 ​​degrees, enabling flexible steering and movement of the equipment in conjunction with the guide wheels 3. When the equipment is in a stationary transport state or in a hoisting working state and needs to be fixed in position, the wheels of the casters 2 are locked to restrict their rotation and prevent the equipment from sliding due to external forces.

[0022] The upper part of the base 1 is rotatably connected to the base 1 through a bearing. The outer ring of the bearing is fixed in the preset mounting hole of the base 1. The rotating shaft 4 is fixedly connected to the inner ring of the bearing, so that the rotating shaft 4 can rotate smoothly relative to the base 1 around its own axis.

[0023] The bottom of the upright frame 5 is fixedly connected to the top of the rotating shaft 4, and their axes are aligned. When the rotating shaft 4 rotates, the upright frame 5 will rotate synchronously around the axis of the rotating shaft 4. At the same time, two first telescopic cylinders 6 are rotatably installed on the top surface of the base 1 on both sides of the rotating shaft 4. The cylinder end of the first telescopic cylinder 6 is rotatably connected to the bracket on the base 1 through a pin, and the movable end of the first telescopic cylinder 6 is rotatably connected to the lower side wall of the upright frame 5 through another set of pins.

[0024] When it is necessary to adjust the angle between the upright frame 5 and the base 1, the movable ends of the two first telescopic cylinders 6 extend or retract synchronously: when the movable end extends, it exerts a pushing force on the side wall of the upright frame 5 connected to it, pushing the upright frame 5 to rotate around the rotation axis 4 in a direction away from the base 1; when the movable end retracts, it exerts a pulling force on the side wall of the pull frame, pulling the upright frame 5 to rotate around the rotation axis 4 in a direction closer to the base 1. By controlling the extension and retraction of the movable ends of the first telescopic cylinders 6, the angle between the upright frame 5 and the base 1 can be adjusted. When the upright frame 5 is parallel to the base 1, the equipment is in a retracted transport state, which facilitates the horizontal transfer of parts; when the upright frame 5 is perpendicular to the base 1, the equipment switches to a hoisting state, providing a structural foundation for subsequent lifting and hoisting operations, thereby providing power support for the equipment to switch between the two functional states.

[0025] A slide rail is provided on the side wall of the upright frame 5 along its length direction. A pulley is installed on the lifting frame 7 at the corresponding position of the slide rail. The pulley is embedded in the slide rail and can roll along the slide rail. Through the cooperation of the slide rail and the pulley, the lifting frame 7 can slide smoothly along the length direction of the upright frame 5, avoiding deviation or jamming during the lifting process.

[0026] A second telescopic cylinder 8 is fixedly installed on the upright frame 5. The cylinder body of the second telescopic cylinder 8 is rigidly connected to the upright frame 5, and its movable end extends downward along the length of the upright frame 5, and its end is fixedly connected to the top of the lifting frame 7. When the movable end of the second telescopic cylinder 8 extends, it pushes the lifting frame 7 to slide downward along the slide rail; when the movable end retracts, it pulls the lifting frame 7 to slide upward along the slide rail. The extension and retraction of the second telescopic cylinder 8 directly provides power for the sliding of the lifting frame 7.

[0027] The inner side of the lifting frame 7 is also equipped with a suitable sliding structure (such as a slide rail and a slider). The hoisting assembly is slidably installed inside the lifting frame 7 through this sliding structure and its position can be adjusted along the length of the lifting frame 7. The core of the hoisting assembly is the hoisting frame 91, which is connected to the lifting frame 7 through the sliding structure inside the lifting frame 7. The hoisting arm 92 is rotatably mounted on the hoisting frame 91, and the hoisting arm 92 is L-shaped, with its bending angle adapted to the force and position requirements during hoisting operations.

[0028] A limit plate 25 is also fixedly installed on the side wall of the hoisting frame 91. When the operator manually or through the drive structure rotates the hoisting arm 92 so that the other end of the hoisting arm 92 is perpendicular to the sliding direction of the hoisting frame 91, the side wall of the hoisting arm 92 will fit against the limit plate 25. The limit plate 25 restricts the hoisting arm 92 from continuing to rotate through mechanical blocking, thereby keeping the hoisting arm 92 stably perpendicular to the hoisting frame 91, providing fixed force support for subsequent hoisting operations.

[0029] A sliding rail is provided on the outer side of the lifting arm 92 along its length. One end of the lifting rod 93 engages with the sliding rail via a slider, allowing the lifting rod 93 to slide along the length of the lifting arm 92. To reduce the sliding friction between the lifting rod 93 and the lifting arm 92, guide wheels can be installed at the contact point between the slider and the sliding rail. The guide wheels roll along the sliding rail, converting sliding friction into rolling friction. If automated control is required, a small telescopic cylinder can be additionally installed between the lifting arm 92 and the lifting rod 93. The cylinder body is fixed to the lifting arm 92, and the movable end is fixedly connected to the lifting rod 93. The extension and retraction of the telescopic cylinder drives the lifting rod 93 to slide automatically.

[0030] The top surface of the lifting rod 93 is machined with a T-shaped groove along its length, or a T-shaped slide rail is fixedly installed. The bottom of the lifting ring 94 corresponds to the shape of the T-shaped groove or T-shaped slide rail and is equipped with a matching T-shaped slider. The T-shaped slider is embedded in the T-shaped groove or T-shaped slide rail and can slide freely along its length. The operator can push the lifting ring 94 to slide laterally on the lifting rod 93 according to the lifting point position of the automotive parts, adjust the position of the lifting ring 94, and make the lifting ring 94 precisely correspond to the lifting point of the parts to ensure force balance during lifting.

[0031] A sprocket 10 is rotatably mounted on the movable end of the second telescopic cylinder 8 via a bearing. The inner ring of the bearing is fixedly connected to the movable end of the second telescopic cylinder 8, and the sprocket 10 is sleeved on the outer ring of the bearing, allowing the sprocket 10 to rotate freely around the axis of the movable end of the second telescopic cylinder 8. A chain 11 is wound around the outer side of the sprocket 10. One end of the chain 11 is fixedly connected to the crossbeam of the lifting frame 7 by bolts, and the other end is fixedly connected to the top of the hoisting frame 91 by bolts.

[0032] When the movable end of the second telescopic cylinder 8 extends and retracts, causing the lifting frame 7 to slide, the lifting frame 7 will pull one end of the chain 11 to move synchronously. The chain 11, through meshing with the sprocket 10, drives the hoisting frame 91 to slide along the sliding structure inside the lifting frame 7. If the lifting frame 7 slides downward, the chain 11 will pull the hoisting frame 91 downward; if the lifting frame 7 slides upward, the chain 11 will push the hoisting frame 91 upward. Through this linkage structure, the sliding direction of the hoisting frame 91 is the same as that of the lifting frame 7, further expanding the height adjustment range of the hoisting components to adapt to hoisting needs of different heights, while ensuring that the height adjustment process is stable and controllable.

[0033] like Figures 3-7As shown, support components are provided on both sides of the base 1. These support components are linked to the rotating shaft 4 on the base 1 through a transmission structure, ensuring that the support components respond synchronously when the rotating shaft 4 moves. A groove is provided on the base 1 corresponding to the installation position of the support component. The size of the groove is adapted to the volume of the support component when it is folded up, accommodating the support component and preventing it from protruding and occupying space during equipment transportation.

[0034] The core transmission component of the support assembly is the rotating shaft 121. The rotating shaft 121 is rotatably mounted in the groove through a bearing. The outer ring of the bearing is fixed in the mounting hole on the side wall of the groove. Both ends of the rotating shaft 121 are fixedly connected to the inner ring of the bearing, so that the rotating shaft 121 can rotate smoothly around its own axis.

[0035] One end of the support arm 122 is fixedly connected to the rotating shaft 121, and their axes are perpendicular. When the rotating shaft 121 rotates, the support arm 122 will rotate synchronously around the axis of the rotating shaft 121, so that the support arm 122 can rotate out of the groove or retract into the groove. The rotating shaft 121 and the rotating shaft 4 transmit power through the first bevel gear set 13. The first bevel gear set 13 includes two meshing bevel gears. One bevel gear is fixedly sleeved on the rotating shaft 4 and rotates synchronously with the rotating shaft 4; the other bevel gear is fixedly sleeved on the end of the rotating shaft 121 and rotates synchronously with the rotating shaft 121. Through the meshing of the two bevel gears, the torque of the rotating shaft 4 is transmitted to the rotating shaft 121, so that the rotating shaft 121 rotates with the rotating shaft 4.

[0036] Meanwhile, a protective cover 26 is fixedly installed on the base 1 at the position corresponding to the first bevel gear set 13. The protective cover 26 is connected to the top surface of the base 1 by bolts, completely covering the outside of the first bevel gear set 13 to form a closed protective space. The protective cover 26 can prevent external debris (such as dust and metal shavings) from entering the bevel gear meshing part, avoiding the impact of debris on the gear transmission accuracy. At the same time, it can prevent the operator from accidentally touching the rotating bevel gear during equipment operation, and can also buffer the impact of external collisions on the bevel gear set, protecting the structural integrity of the first bevel gear set 13.

[0037] The support assembly also includes at least two connecting rods 123. One end of the connecting rod 123 is rotatably connected to the other end of the support arm 122 via a pin, so that the connecting rod 123 can rotate relative to the support arm 122 around the pin. The other ends of all the connecting rods 123 are rotatably connected to the support foot 124 via the same pin. The support foot 124 is flat to increase the contact area with the ground. When the connecting rod 123 rotates, it can drive the support foot 124 to move away from or towards the support arm 122. A bevel gear ring 14 is fixedly installed on the base 1 at the inner position corresponding to the rotation trajectory of the support arm 122. The axis of the bevel gear ring 14 coincides with the axis of the rotating shaft 4, and its tooth surface faces the support arm 122. A linkage rod 15 is rotatably mounted on the middle position of the support arm 122 via a bearing. The axis of the linkage rod 15 is consistent with the length direction of the support arm 122, and it can rotate relative to the support arm 122 around its own axis. A driven bevel gear 16 is fixedly installed at one end of the linkage rod 15. The driven bevel gear 16 meshes with the tooth surface of the bevel gear ring 14, and the driven bevel gear 16 can roll along the tooth surface of the bevel gear ring 14 as the support arm 122 rotates.

[0038] When the support arm 122 rotates out of the groove along with the rotating shaft 121, the support arm 122 drives the linkage rod 15 and the driven bevel gear 16 to move synchronously. Since the bevel gear ring 14 is fixed, the driven bevel gear 16 will rotate during the rolling process along the tooth surface of the bevel gear ring 14, thereby driving the linkage rod 15 to rotate around its own axis. The other end of the linkage rod 15 is transmitted to the rotation center shaft of one of the connecting rods 123 through the second bevel gear set 17. The second bevel gear set 17 also includes two meshing bevel gears. One bevel gear is fixedly sleeved on the end of the linkage rod 15 and rotates synchronously with the linkage rod 15; the other bevel gear is fixedly sleeved on the rotation center shaft of the connecting rod 123. This shaft is the pin connecting the connecting rod 123 and the support arm 122, and rotates synchronously with the shaft. Through the meshing of the two bevel gears, the torque of the linkage rod 15 is transmitted to the rotation center shaft of the connecting rod 123, causing the connecting rod 123 to rotate around its own rotation center shaft.

[0039] Since all the connecting rods 123 are rotatably connected to the support foot 124, when one of the connecting rods 123 rotates under the drive of the second bevel gear set 17, it will push the other connecting rods 123 to rotate synchronously through the support foot 124, so that all the connecting rods 123 unfold away from the support arm 122, thereby driving the support foot 124 to move towards the ground until the support foot 124 is in close contact with the ground. At this time, the support foot 124 forms a stable support structure with the base 1 through the connecting rod 123, the support arm 122, and the rotating shaft 121, increasing the contact area between the equipment and the ground, dispersing the load during equipment hoisting, and preventing the base 1 from tilting due to excessive local force. When the support arm 122 retracts into the groove, the driven bevel gear 16 rolls in the opposite direction and drives the linkage rod 15 to rotate in the opposite direction. Through the second bevel gear set 17, the connecting rod 123 rotates in the opposite direction, causing the connecting rod 123 to retract towards the support arm 122. The support foot 124 leaves the ground along with the connecting rod 123 and finally retracts into the groove along with the support arm 122, without affecting the movement of the equipment.

[0040] It should be noted that the rotation angle of the rotating shaft 121 can be adjusted by adjusting the transmission ratio between the bevel gear sets. For example, if the transmission ratio is 1:2, the rotating shaft 4 rotates 90 degrees, while the rotating shaft 121 only rotates 45 degrees, thus making the angle between the support arm 122 and the base 1 45 degrees. This application does not limit the parameters of the gear set. A rotating seat 19 is bolted to the side wall of the support frame 5. The rotating seat 19 has a hollow structure, and a handle 20 is movably installed inside it. The middle part of the handle 20 is rotatably connected to the rotating seat 19 by a pin, so that the handle 20 can freely rotate around the pin within the rotating seat 19. The inner wall of the rotating seat 19 is provided with positioning grooves 21, which are symmetrically arranged on both sides of the rotation center of the handle 20 (i.e., the axis of the pin). The positions of the two sets of positioning grooves 21 correspond to the two key states of the handle 20: "retracted" and "operated".

[0041] A positioning shaft 22 is fixedly installed on the side of the handle 20 near the rotating seat 19. The axis of the positioning shaft 22 is parallel to the rotation axis 4 of the handle 20, and the diameter of the positioning shaft 22 is adapted to the width of the positioning groove 21, so that it can be embedded in the positioning groove 21. At the same time, a spring 23 is sleeved on the pin of the handle 20. One end of the spring 23 abuts against the side wall of the handle 20, and the other end abuts against the inner wall of the rotating seat 19. In its natural state, the spring 23 pushes the positioning shaft 22 with its own elastic force, always tending to embed into the positioning groove 21.

[0042] When the handle 20 needs to be adjusted, the operator pulls the handle 20 upwards, causing the positioning shaft 22 to disengage from the currently embedded positioning groove 21, and the spring 23 is further compressed. Then, the handle 20 is flipped to the target position, the handle 20 is released, the spring 23 returns to its deformation, and pushes the positioning shaft 22 into the corresponding positioning groove 21, thereby locking the position of the handle 20 and preventing the handle 20 from flipping on its own due to vibration during equipment operation, thus ensuring operational safety and stability.

[0043] In addition, a pull rod 18 is rotatably mounted on the end of the base 1 via a bearing. The pull rod 18 can rotate around its connection point with the base 1. When the equipment is in the retracted state and needs to be moved, the operator can rotate the pull rod 18 to a horizontal position, grasp the pull rod 18, and drag the base 1. With the help of the casters 2 and guide wheels 3 at the bottom of the base 1, the equipment can be moved easily. When dragging is not required, the pull rod 18 can be rotated to a vertical position that fits against the base 1, avoiding taking up extra space and not affecting the operation of other components of the equipment.

[0044] Working principle: During the use of this invention, such as Figure 5As shown, when the equipment is in the retracted state, all components are in a compact storage position: the movable end of the first telescopic cylinder 6 is fully retracted, and the length of its cylinder body and movable end is at its shortest. At this time, the base 1 and the upright 5, which are rotatably connected to both ends of the first telescopic cylinder 6, approach each other and finally reach a parallel and overlapping state. The upright 5 is attached to the top surface of the base 1 and does not occupy additional vertical space. The movable end of the second telescopic cylinder 8 is also fully retracted. Since the cylinder body of the second telescopic cylinder 8 is fixed on the upright frame 5 and the movable end is fixedly connected to the lifting frame 7, the retracted movable end pulls the lifting frame 7 to slide along the slide rail of the upright frame 5 to the lowest position of the upright frame 5, so that the lifting frame 7 is close to the lower part of the upright frame 5; the lifting arm 92 rotates around the pivot 121 on the lifting frame 91 to the position that coincides with the upright frame 5, and the lifting arm 92 is close to the side wall of the upright frame 5 to avoid lateral protrusion. All components of the support assembly are completely retracted into the groove of the base 1. The support arm 122 rotates into the groove with the pivot 121, and the connecting rod 123 and the support foot 124 retract, with the entire assembly not exceeding the outline of the base 1. At this time, the equipment is flat and can move on the ground like a pallet jack using the casters 2 and guide wheels 3 at the bottom of the base 1. The operator can drag the equipment using the pull rod 18 on the base 1 to achieve horizontal transport and transfer of automotive parts.

[0045] When it is necessary to lift automotive parts, such as Figure 1-2 As shown, the operator extends the movable end of the first telescopic cylinder 6 outward through the control device. Since the cylinder body of the first telescopic cylinder 6 is rotatably connected to the base 1 and the movable end is rotatably connected to the upright frame 5, the extended movable end generates a thrust on the upright frame, pushing the upright frame 5 to rotate around the rotation axis 4 on the base 1 until the upright frame 5 and the base 1 are in a vertical state. The upright frame 5 stands vertically on the top surface of the base 1, providing a vertical support foundation for subsequent hoisting.

[0046] During the rotation of the upright frame 5, the upright frame 5 drives the rotating shaft 4, which is fixedly connected to it, to rotate synchronously around its own axis on the base 1. The rotating shaft 4 transmits torque to the rotating shaft 121 of the support assembly through the first bevel gear set 13, which consists of two meshing bevel gears, respectively fixed to the rotating shaft 4 and the rotating shaft 121 of the support assembly, causing the rotating shaft 121 to rotate within the groove of the base 1. The rotation angle of the rotating shaft 121 can be controlled by adjusting the transmission ratio of the first bevel gear set 13 (i.e., the ratio of the number of teeth of the two bevel gears). For example, when the transmission ratio is 1:2, the rotating shaft 4 rotates 90 degrees (the upright frame 5 rotates from parallel to vertical), while the rotating shaft 121 only rotates 45 degrees, thereby causing the support arm 122, which is fixedly connected to the rotating shaft 121, to rotate out of the groove. Finally, a 45-degree angle is formed between the support arm 122 and the base 1. The specific angle can be adjusted by the transmission ratio according to the actual support requirements; no specific parameters are limited here.

[0047] As the support arm 122 rotates out of the groove, the supporting leg 124 unfolds synchronously. Simultaneously, the linkage rod 15, rotatably mounted in the middle of the support arm 122, moves accordingly. The driven bevel gear 16, fixed at one end of the linkage rod 15, meshes with the bevel gear ring 14 fixed in the groove of the base 1. Since the bevel gear ring 14 remains stationary, when the support arm 122 moves, the driven bevel gear 16 rolls along the tooth surface of the bevel gear ring 14 and rotates, thereby driving the linkage rod 15 to rotate around its own axis on the support arm 122. The other end of the linkage rod 15 transmits torque to the rotation center axis of the connecting rod 123 via a second bevel gear set 17 (also composed of two meshing bevel gears, respectively fixed on the rotation center axis of the linkage rod 15 and one of the connecting rods 123), causing the connecting rod 123 to rotate around the pin connecting it to the support arm 122. Since the other end of all connecting rods 123 is rotatably connected to the support foot 124, when one connecting rod 123 rotates, it will push the other connecting rods 123 to rotate synchronously through the support foot 124, causing all connecting rods 123 to unfold away from the support arm 122. This ultimately drives the support foot 124 to move towards the ground until it makes tight contact with the ground, providing stable support to both sides of the base 1. The rotation angle of the connecting rod 123 and the rotation angle of the linkage rod 15 can be controlled by the transmission ratio of the second bevel gear set 17 to ensure that the support foot 124 can smoothly contact the ground after unfolding. This section only explains the principle and does not limit specific parameters.

[0048] like Figure 1-2 As shown, after the lifting components are adjusted and the lifting operation is carried out, and the support arm 122 and support legs 124 are fully extended and the entire equipment is in a stable supported state, the operator manually or through the drive structure rotates the lifting arm 92, causing the lifting arm 92 to rotate around the pivot 121 on the lifting frame 91. When the lifting arm 92 rotates to a position perpendicular to the lifting frame 91, the limiting plate 25 fixed on the lifting frame 91 abuts against the side wall of the lifting arm 92, mechanically restricting the lifting arm 92 from continuing to rotate, so that the lifting arm 92 is stably kept in a state perpendicular to the lifting frame 91, providing a fixed force angle for the lifting operation.

[0049] Subsequently, the operator can adjust the position of the lifting components: the lifting rod 93 can slide along the sliding track on the lifting arm 92 (friction can be reduced by guide wheels or automatic sliding can be achieved with the help of an additional telescopic cylinder), adjusting the length of the lifting rod 93 extending beyond the lifting arm 92; the lifting ring 94 can slide laterally along the T-shaped groove or T-shaped slide rail on the lifting rod 93, adjusting the lateral position of the lifting ring 94 so that the lifting ring 94 precisely corresponds to the lifting point of the automotive part. A hook can also be installed on the lifting ring 94 for lifting parts. After adjustment, the parts can be hooked onto the lifting ring 94 for lifting operations.

[0050] When the equipment is in its retracted state, it can easily transport goods like a pallet jack thanks to its flat structure, universal wheels 2, and guide wheels 3. When switched to the extended state, the support arm 122 and support foot 124 extend and form a specific angle with the base 1, significantly increasing the contact area between the equipment and the ground, distributing the load during hoisting, preventing the equipment from tilting, and ensuring stability during the hoisting process. Throughout the entire state switching process, the rotation of the upright 5 and the extension of the support components are linked by a bevel gear set, requiring no additional separate control, simplifying the operation process and improving work efficiency.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
