Description

Technical Field

[0001] This invention relates to the field of industrial equipment handling technology, and in particular to a handling vehicle. Background Technology

[0002] In industrial production, lead-acid batteries are widely used in energy storage and power supply fields due to their low cost and wide applicability. Currently, the handling of lead-acid batteries faces two main challenges: First, traditional manual handling methods are inefficient and risky. A single battery cell often weighs over 100kg, requiring 4-6 people to work together, exceeding the safety threshold for each person's workload. Industry data shows that accidents caused by coordination errors account for as much as 38%, and electrolyte leakage on the battery surface can cause slippage (accounting for 42% of accidents), easily leading to limb fractures and chemical burns.

[0003] Secondly, existing material handling equipment is not sufficiently adaptable. 80% of industrial material handling equipment on the market has a volume exceeding 1.2m. 3 These devices are ill-suited for battery compartment passageways with an average width of only 1.5m. Furthermore, the lack of dedicated securing devices results in a 23% damage rate to battery casings and a 17% internal failure rate during transport, causing significant economic losses for the company.

[0004] Existing improvement solutions, such as dedicated handles and conveyors, have improved manual handling conditions or increased automation to some extent, but still have problems such as poor space adaptability, insufficient leakage protection, and poor ease of operation.

[0005] Therefore, there is an urgent need to develop a specialized handling device to address key issues such as adaptability to confined spaces, handling stability, and operational safety. Summary of the Invention

[0006] The purpose of this invention is to provide a transport vehicle to solve the problems existing in the prior art. The U-shaped opening on the chassis facilitates the entry of the transported items, which can be lifted by the lifting component and placed on the support plate. This makes it easy to place the transported items on the transport vehicle for transport, improves adaptability to narrow spaces, and enhances transport stability and operational safety.

[0007] To achieve the above objectives, the present invention provides the following solution: This invention provides a transport vehicle, including a chassis, a body, a lifting assembly, and wheels. The chassis has a U-shaped opening for the lateral entry of the transported object, and a support plate for supporting the transported object is movably disposed on the top of the U-shaped opening. The body is mounted on the chassis. The lifting assembly includes a lifting rope and a lifting device mounted on the body. The lifting device is connected to the lifting rope, and the lifting end of the lifting rope is located above the chassis. The wheels are mounted on the chassis.

[0008] In one embodiment, the chassis includes horizontal tubes and longitudinal tubes, with two horizontal tubes and one longitudinal tube connected to form a U-shaped structure. The longitudinal tube is used to connect the vehicle body, and a stepped surface is provided on one side of the two horizontal tubes opposite each other. The stepped surface is used to place the load-bearing plate.

[0009] In one embodiment, the vehicle body includes a vertical pole, a horizontal pole, a first diagonal pole, and a second diagonal pole. The bottom end of the vertical pole is connected to the longitudinal tube. The first diagonal pole is provided on both sides of the vertical pole, and the two ends of the first diagonal pole are respectively connected to the vertical pole and the longitudinal tube. The vertical pole, the first diagonal pole, and the longitudinal tube are combined to form a first triangular structure. The horizontal pole is vertically connected to the top end of the vertical pole. The second diagonal pole is also provided between the horizontal pole and the vertical pole. The two ends of the second diagonal pole are respectively connected to the horizontal pole and the vertical pole. The horizontal pole, the vertical pole, and the second diagonal pole are combined to form a second triangular structure.

[0010] In one embodiment, a reversing structure is also included, wherein the lifting device is installed upside down on the upright, the working end of the lifting device raises and lowers the hoisting rope, and the hoisting rope extends downward toward the chassis after passing around the reversing structure by the lifting device.

[0011] In one embodiment, the reversing structure includes a first fixed pulley and a second fixed pulley. The first fixed pulley is installed on the side of the upright, and the second fixed pulley is installed on the top of the crossbar. The hoisting rope is smoothly passed over the first fixed pulley and the second fixed pulley by the lifting device.

[0012] In one embodiment, the device further includes an angle iron and a baffle, both of which are connected to the upright. A locking space for installing the lifting device is formed between the baffle and the angle iron. The baffle is L-shaped and fastens to the top of the lifting device, and the angle iron is located at one bottom corner of the lifting device.

[0013] In one embodiment, the device further includes a fixing hook and a fixing ring. The fixing hook is installed at the bottom of the lifting device, and the fixing ring is installed on the upright. The fixing hook is connected to the fixing ring to provide a tension opposite to that of the lifting rope.

[0014] In one embodiment, the system further includes a fence, which includes a first movable fence, a second movable fence, a third movable fence, and a fixed fence fixedly connected to the longitudinal tube. The first and second movable fences are sequentially hinged to one side of the fixed fence, and the third movable fence is hinged to the other side of the fixed fence. The second and third movable fences are connected by snap-fit ​​fasteners.

[0015] In one embodiment, the device further includes a clamp comprising a hanging ring and a sling, the sling being used to pass around the bottom of the object being transported, both ends of the sling being connected to the hanging ring, the sling being connected to a hook, and the hanging ring being used to connect to the hook.

[0016] In one embodiment, the device further includes scissor clamps and clamping plates. The hanging ring is connected to the boom, and the two ends of the boom are respectively hinged to the scissor clamps. The clamping end of the scissor clamp is connected to the clamping plate. The two clamping plates of the same scissor clamp are located on both sides of the object being transported, and the two ends of the sling are respectively connected to the two scissor clamps.

[0017] The present invention achieves the following technical effects compared to the prior art: This invention utilizes a U-shaped opening on the chassis to facilitate the entry of transported items. The lifting assembly can then lift the items and place them on a support plate, making it easier to load them onto a transport vehicle for transport. This improves adaptability to confined spaces and enhances transport stability and operational safety compared to manual handling. Attached Figure Description

[0020] 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.

[0021] The purpose of this invention is to provide a transport vehicle to solve the problems existing in the prior art. The U-shaped opening on the chassis facilitates the entry of the transported items, which can be lifted by the lifting component and placed on the support plate. This makes it easy to place the transported items on the transport vehicle for transport, improves adaptability to narrow spaces, and enhances transport stability and operational safety.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1-6As shown, this invention provides a transport vehicle, including a chassis 2, a body 1, a lifting assembly 4, and wheels 6. The chassis 2 has a U-shaped opening for the lateral entry of a transported object 7. That is, for an object 7 (such as a lead-acid battery) placed on the ground or a platform, the transport vehicle can be positioned around the object 7 through the U-shaped opening. A support plate 23 for supporting the transported object 7 is movably mounted on the top of the U-shaped opening. In practice, when the object 7 needs to be inserted into the U-shaped opening, the support plate 23 is already opened or detached from the U-shaped opening. The support plate 23 can be hinged to one of the arms or the bottom arm of the U-shaped opening, slidably connected to the chassis 2, or simply placed on the chassis 2. In other words, the support plate 23 can be opened by sliding, flipping, or direct removal. The body 1 is mounted on the chassis 2 and has a certain height, allowing the transported object 7 to be lifted to a certain height after the lifting assembly 4 is installed. The lifting assembly 4 includes a lifting rope 42 and a lifting device 41 mounted on the vehicle body 1. The lifting device 41 connects to the lifting rope 42, such as a winch or hoist. The lifting end of the rope 42 is located above the chassis 2. By connecting the lifting end of the rope 42 to the object 7 being transported (either by direct binding or by hanging it via a hook 43), the lifting device 41 can lift and lower the object 7 under the action of retracting and extending the rope 42. Wheels 6 are mounted on the chassis 2 to facilitate the movement of the transport vehicle. The wheels 6 can be swivel casters, one-way casters, or a combination of both, and can be driven manually or electrically. Additionally, handrails can be provided for easy movement of the transport vehicle. The handrails can be mounted on the vehicle body 1 or on the lifting device 41.

[0024] The present invention utilizes the U-shaped opening on the chassis 2 to facilitate the entry of the transported object 7, so that it can be lifted by the lifting component 4 and placed on the support plate 23. This makes it easier to place the transported object 7 on the transport vehicle for transport, improving adaptability to narrow spaces. At the same time, compared with manual handling, it improves the stability of handling and the safety of operation.

[0025] In one implementation, such as Figure 4 and Figure 5As shown, the chassis 2 includes horizontal tubes 21 and vertical tubes 22. Two horizontal tubes 21 and one vertical tube 22 are connected to form a U-shaped structure. The connection is made by welding or bolting to ensure the connection strength. The wheels 6 are distributed at the bottom of the U-shaped structure to support the movement of the chassis 2. The vertical tube 22 is used to connect the vehicle body 1, that is, the vehicle body 1 is located on one side of the chassis 2. At this time, after the transported object 7 is lifted, it can be located directly above the chassis 2, thereby ensuring the stability of the center of gravity of the transport vehicle and avoiding tilting that could lead to overturning. A stepped surface 211 is provided on the opposite side of the two horizontal tubes 21. The stepped surface 211 is used to place the bearing plate 23. That is, the bearing plate 23 can be placed on the stepped surface 211, located between the two horizontal tubes 21, to prevent the transported object 7 it carries from shifting relative to the chassis 2 due to the displacement of the bearing plate 23.

[0026] In one implementation, such as Figure 3 and Figure 4 As shown, the vehicle body 1 includes a vertical rod 11, a horizontal rod 12, a first diagonal rod 14, and a second diagonal rod 13. The bottom end of the vertical rod 11 is connected to the longitudinal tube 22 by welding or bolting. The first diagonal rod 14 is provided on both sides of the vertical rod 11, and its two ends are connected to the vertical rod 11 and the longitudinal tube 22, respectively. The vertical rod 11, the first diagonal rod 14, and the longitudinal tube 22 form a first triangular structure to ensure the stability of the connection between the vertical rod 11 and the longitudinal tube 22. The horizontal rod 12 is vertically connected to the top of the vertical rod 11. A second diagonal rod 13 is also provided between the horizontal rod 12 and the vertical rod 11, and its two ends are connected to the horizontal rod 12 and the vertical rod 11, respectively. The horizontal rod 12, the vertical rod 11, and the second diagonal rod 13 form a second triangular structure to ensure the stability of the connection between the horizontal rod 12 and the vertical rod 11.

[0027] In one implementation, such as Figure 3 As shown, it also includes a reversing structure 44. The lifting device 41 is installed upside down on the upright 11. The working end of the lifting device 41 raises and lowers the lifting rope 42. The lifting rope 42 extends from the lifting device 41, passes around the reversing structure 44, and extends downward toward the chassis 2. The reversing structure 44 guides the direction of the lifting rope 42. By changing the direction of the lifting rope 42, the lifting device 41 can be installed on the side of the upright 11, avoiding the increase in the overall height of the transport vehicle caused by installing the lifting device 41 on the top of the upright 11. This reduces the height of the transport vehicle and is suitable for applications in height-restricted spaces.

[0028] In one implementation, such as Figure 3As shown, the reversing structure 44 includes a first fixed pulley 441 and a second fixed pulley 442. The first fixed pulley 441 is installed on the side of the upright 11 to match the position of the lifting device 41, realizing the first-stage reversal of the lifting rope 42. The second fixed pulley 442 is installed on the top of the crossbar 12 to match the position of the chassis 2, realizing the second-stage reversal of the lifting rope 42. Thus, after the lifting rope 42 extends from the lifting device 41 and smoothly passes over the first fixed pulley 441 and the second fixed pulley 442, it can be used to lift the object 7 being transported in the vertical direction of the chassis 2.

[0029] In one implementation, such as Figure 3 As shown, it also includes angle iron 414 and baffle 413. Both angle iron 414 and baffle 413 are connected to the upright 11 by welding. A locking space is formed between the baffle 413 and the angle iron 414 for installing the lifting device 41. The baffle 413 provides a barrier against the upward movement of the lifting device 41. One or more baffles 413 can be arranged side by side. When two baffles are arranged, they can be connected to both sides of the upright 11 by support rods. The baffle 413 is L-shaped and fastened to the top of the lifting device 41 to block the lifting device 41 from moving away from the upright 11. The angle iron 414 is located at one bottom corner of the lifting device 41 and can be used to position and place the lifting device 41.

[0030] In one implementation, such as Figure 3 As shown, it also includes a fixing hook 411 and a fixing ring 412. The fixing hook 411 is installed at the bottom of the lifting device 41, and the fixing ring 412 is installed on the upright 11. The fixing hook 411 and the fixing ring 412 are connected to provide a tension opposite to that of the hoisting rope 42, that is, together with the baffle 413, they bear the reverse fixing force for the operation of the lifting device 41.

[0031] In one implementation, such as Figure 4 and Figure 5As shown, it also includes a fence 3, which includes a first movable fence 32, a second movable fence 33, a third movable fence 34, and a fixed fence 31 fixedly connected to the longitudinal tube 22. The first movable fence 32 and the second movable fence 33 are sequentially hinged to one side of the fixed fence 31, meaning that the first movable fence 32 can tilt relative to the fixed fence 31, and the second movable fence 33 can tilt relative to the first movable fence 32. This expands the movement space of the second movable fence 33, allowing the chassis 2 to have a larger open space. The third movable fence 34 is hinged to the other side of the fixed fence 31, and the third movable fence 34 can tilt relative to the fixed fence 31. The second movable fence 33 and the third movable fence 34 are connected by a buckle 35. That is, the fixed fence 31, the first movable fence 32, the second movable fence 33, and the third movable fence 34 together form a ring fence 3, which can place the transported object 7 inside the fence 3, protecting the transported object 7 and reducing the risk of collision and falling. The fixed railing 31, the first movable railing 32, the second movable railing 33 and the third movable railing 34 may also be provided with cushioning foam pads on the side facing the object 7 to reduce the damage to the object 7 caused by bumps.

[0032] In one implementation, such as Figure 6 As shown, it also includes a clamp 5, which includes a hanging ring 51 and a sling 54. The sling 54 is used to go around the bottom of the object 7 being transported. Both ends of the sling 54 are connected to the hanging ring 51. The lifting rope 42 is connected to the hook 43. The hanging ring 51 is used to connect to the hook 43. Thus, after the hook 43 hooks the hanging ring 51, the object 7 being transported can be lifted by the action of the sling 54.

[0033] In one implementation, such as Figure 6 As shown, it also includes scissor clamps 52 and clamping plates 53. Hanging rings 51 are connected to the lifting rod 55. Scissor clamps 52 are hinged to both ends of the lifting rod 55. The clamping ends of the scissor clamps 52 are connected to clamping plates 53. The two clamping plates 53 of the same scissor clamp 52 are located on both sides of the object 7 being transported. When the lifting rod 55 is subjected to an upward pulling force, the clamping ends of the scissor clamps 52 contract, thereby clamping the object 7 being transported. The two ends of the sling 54 are connected to the two scissor clamps 52 respectively. Thus, it can both clamp the object 7 being transported laterally and support the object 7 being transported from the bottom, thereby improving the stability and safety when lifting the object 7 being transported.

[0034] The present invention provides the following method for using the transport vehicle: 1. The operator pushes the transport vehicle to the storage point of the transported item 7 (such as a battery), removes the fence 3 by pressing the buckle 35 on the fence 3, and then holds the handle on the support plate 23 (or directly grabs the support plate 23 with his hand) to lift or pull out the support plate 23.

[0035] 2. Push the transport vehicle close to the battery, start the control button of the inverted electric hoist (lifting device 41), and drive the hook 43 to the battery lifting point through the reversing structure 44 (pulley group composed of the first fixed pulley 441 and the second fixed pulley 442), and firmly connect the hook 43 to the battery lifting hole (or the hanging ring 51 of the clamp 5).

[0036] 3. Restart the electric hoist to lift the battery and smoothly insert it into the U-shaped opening. After insertion, slowly insert the support plate 23 to place the battery securely on the support plate 23. Then quickly install the guardrail 3, ensuring that the cushioning foam pad fits tightly against the four corners of the battery, and secure the guardrail 3 with the buckles 35.

[0037] 4. Push the transport vehicle and use the omnidirectional wheels in the travel wheels 6 to transport the battery to the battery rack. Once there, remove the fence 3 to release the battery from its fixed position.

[0038] 5. Restart the electric hoist and use the pulley system to lift the battery to a height level with the battery rack installation position (e.g., 1.1 meters).

[0039] 6. Using the structure at the bottom of the transport vehicle that can be inserted under the battery rack, push the transport vehicle forward to accurately position the battery in the installation position, and then slowly lower the battery.

[0040] 7. Remove hook 43, pull the transport vehicle out from under the battery rack, and pull out the support plate 23 to prepare for transporting the next battery.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
