Description

Technical Field

[0001] The utility model relates to the technical field of transport vehicles, in particular to a material lifting transport vehicle. Background Art

[0002] In modern industrial production and logistics warehousing, material handling and transshipment are essential components of daily operations. Traditional material handling methods rely primarily on manual labor, which is labor-intensive and inefficient, making it difficult to meet growing production demands. In large enterprise warehouses, especially, material transfers are frequent, requiring employees to frequently bend over to retrieve materials. This repetitive motion not only increases labor intensity but can also have long-term effects on employees' back health.

[0003] While some material handling tools, such as forklifts and transport trucks, are already available on the market, these devices are often bulky, complex to operate, and expensive, making them unsuitable for frequent use in warehouses with limited space. Furthermore, these devices often lack automatic material lifting and lowering capabilities, requiring workers to bend over, thus failing to fundamentally address the labor intensity and low efficiency issues.

[0004] Therefore, it is necessary to design a new type of material handling tool to improve the efficiency of material handling and reduce the labor intensity of employees. Utility Model Content

[0005] In order to overcome the problems existing in the related technology, the purpose of the present utility model is to provide a material lifting and transporting vehicle, which can maintain the material carrying platform at an appropriate height through an elastic structure, reduce the frequency of workers bending over to pick up goods, and reduce the problem of waist damage caused by frequent bending over; and the entire transport vehicle can realize the transfer of materials, which can effectively improve the material handling efficiency.

[0006] A material lifting and transporting vehicle comprises a base and a material carrying platform; a bracket is provided on the base, and the material carrying platform can be raised and lowered on the bracket; an elastic structure is provided on the base, and the elastic structure is used to apply a force to the material carrying platform so that the material carrying platform is maintained at a target height.

[0007] During use, the material lift truck maintains the material loading platform at an appropriate height through an elastic structure, which can reduce the frequency of workers bending over, reduce physical fatigue and potential injuries caused by long-term repetitive movements, and improve work comfort. Using a lift truck to transport goods can effectively improve cargo handling efficiency and reduce cargo circulation costs.

[0008] In a preferred technical solution of the present utility model, the elastic structure includes a spring, which is fixed on the base and located on one side of the material carrying platform;

[0009] A fixed pulley is provided on the bracket, and a pull wire is provided on the fixed pulley. One end of the pull wire is fixedly connected to the spring, and the other end thereof is fixedly connected to the material carrying platform.

[0010] The spring, working in conjunction with the fixed pulley and the cable, applies an upward force to the material platform, raising it to a certain height. Conversely, as the weight on the platform increases, the platform lowers accordingly. This allows the platform to automatically maintain a relatively stable height under varying loads, significantly reducing the need for operators to frequently bend or reach to adjust the platform's height.

[0011] In a preferred technical solution of the present invention, the fixed pulley, the pulling wire and the spring form a tension providing group, two tension providing groups are provided, and the two tension providing groups are symmetrically arranged about the middle of the material carrying platform.

[0012] Two symmetrically positioned tensioning elements ensure the platform maintains greater stability and balance during lifting. Even with uneven load distribution, the platform is effectively prevented from tilting or shifting, ensuring safe and accurate handling.

[0013] In a preferred technical solution of the present invention, the elastic structure includes an elastic support member, which is arranged on the base and located below the material carrying platform, and the elastic support member is connected to the top of the material carrying platform.

[0014] In this embodiment, the elastic support member is disposed below the material carrying platform, thereby applying an upward force to the material carrying platform, so that the material carrying platform is maintained at a suitable height.

[0015] In a preferred technical solution of the present invention, the bracket includes at least one support rod and at least one first guide rod, the support rod and the first guide rod are both fixed to the base, the first guide rod is located on one side of the support rod, and the first guide rod is connected to the support rod via a connecting plate;

[0016] A first sliding sleeve is provided on one side of the material carrying platform, and the first sliding sleeve is sleeved on the first guide rod.

[0017] The first guide rod and sleeve structure significantly enhance the stability of the material carrier during lifting. The guide rod provides a clear lifting path for the material carrier, effectively preventing it from shifting or shaking during the lifting process. The support rod and the first guide rod are connected by a connecting plate, enhancing the overall rigidity and deformation resistance of the bracket. This structural design allows the bracket to withstand greater loads and longer use, thereby extending the service life of the material lift truck.

[0018] In a preferred technical solution of the present utility model, the base includes a mounting frame, and the bracket is fixed on the mounting frame;

[0019] A plurality of connecting rods are arranged in the installation frame, and the plurality of connecting rods are arranged in parallel in the installation frame.

[0020] The installation of connecting rods creates a more stable grid-like structure on the base frame, effectively improving the overall structural stability of the vehicle. This design allows the material lift truck to maintain a stable posture when carrying heavy objects, reducing safety hazards caused by equipment shaking and allowing the material lift truck to withstand greater loads. The connecting rods can be made of aluminum alloy.

[0021] In a preferred technical solution of the present invention, each of the connecting rods is provided with a mounting groove, the mounting groove is arranged along the length direction of the connecting rod, and a plurality of rollers are arranged in the mounting groove.

[0022] The connecting rod can be used to carry goods, while the rollers make it easy to adjust the position of the goods on the base to improve the efficiency of cargo handling.

[0023] In a better technical solution of the present invention, a connecting frame is provided at both opposite ends of each connecting rod, and a card slot is provided on the connecting frame, and the card slot is adapted to the mounting frame, and the connecting rod is connected to the mounting frame through the matching card slot with the mounting frame.

[0026] The control handle is used to control the movement of the entire truck. The hinged design between the control handle and the mounting bracket allows the operator to freely adjust the angle and position of the handle within a certain range to adapt to different operating habits and working environments, which can improve the flexibility of truck control.

[0027] In a preferred technical solution of the present invention, a universal wheel is provided at the bottom of the base, and a locking device is provided on the universal wheel.

[0028] The universal wheels can rotate 360 ​​degrees freely, allowing the transporter to move easily in various directions and in small spaces, greatly improving transportation efficiency and convenience. The universal wheels are equipped with a locking function, allowing the operator to firmly lock the transporter in a specific position when needed.

[0029] In one application, when the truck needs to be moved, the lock is opened, allowing the operator to push the truck to the target location for cargo transfer. Once the cargo is in place and needs to be unloaded, the lock is tightened, effectively locking the universal wheels. The universal wheels are now fixed, preventing the truck from moving and allowing the operator to unload the cargo. The lock improves the safety of the truck during use.

[0042] The following describes preferred embodiments of the present invention in more detail with reference to the accompanying drawings. Although preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0043] In modern industrial production and logistics warehousing, material handling and transshipment are essential components of daily operations. Traditional material handling methods rely primarily on manual labor, which is labor-intensive and inefficient, making it difficult to meet growing production demands. In large enterprise warehouses, especially, material transfers are frequent, requiring employees to frequently bend over to retrieve materials. This repetitive motion not only increases labor intensity but can also have long-term effects on employees' back health.

[0044] While some material handling tools, such as forklifts and transport trucks, are already available on the market, these devices are often bulky, complex to operate, and expensive, making them unsuitable for frequent use in warehouses with limited space. Furthermore, these devices often lack automatic material lifting and lowering capabilities, requiring workers to bend over, thus failing to fundamentally address the labor intensity and low efficiency issues.

[0045] Based on this, the present application provides a material lifting and transporting vehicle.

[0046] Example 1

[0047] like Figures 1-8 As shown, the present embodiment provides a material lifting and transporting vehicle, comprising a base 1 and a material carrying platform 2; a bracket 3 is provided on the base 1, and the material carrying platform 2 can be raised and lowered on the bracket 3; an elastic structure is provided on the base 1, and the elastic structure is used to apply a force to the material carrying platform 2 so that the material carrying platform 2 is maintained at a target height.

[0048] Specifically, the support 3 supports and guides the lifting and lowering movement of the material carrier 2. The design of the bracket 3 ensures the stability and safety of the material carrier 2 during the lifting process. In one embodiment, the material carrier 2 can be driven to move up and down by a lifting mechanism. The elastic structure applies a force to the material carrier 2, which can be a pulling force or a pushing force, to maintain the material carrier 2 at a target height. The target height is set according to the daily usage habits of the staff.

[0049] For example, the target height may be the waist position of the worker, that is, the material carrying platform 2 can be maintained at the waist position of the worker when there is no external force, which can reduce the defect that the worker needs to bend frequently when taking and placing items.

[0050] The base 1 is provided with a universal wheel 7 at its bottom, equipped with a lock 71. The universal wheel 7 can rotate 360 ​​degrees, allowing the transporter to move easily in various directions and within confined spaces, greatly improving transport efficiency and ease of use. The lock 71 on the universal wheel 7 allows the operator to securely lock the transporter in a specific position when needed.

[0051] Specifically, the lock 71 of the present application can be a brake locking device, which is usually fixed by pressing or rotating the locking device. Alternatively, the lock 71 can be locked by an elastic piece. For example, by pressing down on the pedal, one end of the elastic piece bends downward and the other end rises upward, so that the limit portion on the raised end of the elastic piece is embedded in the limit groove, and the locking purpose is achieved by the snap connection.

[0052] During use, the material lifting and transporting vehicle maintains the material carrying platform 2 at an appropriate height through an elastic structure, which can reduce the frequency of workers bending over to operate, reduce physical fatigue and potential injuries caused by long-term repetitive movements, and improve work comfort. Using the lifting and transporting vehicle to transport goods can effectively improve the efficiency of goods handling and reduce the cost of goods circulation.

[0053] Example 2

[0054] This embodiment is improved on the basis of embodiment 1.

[0055] like Figures 1-8 As shown, in this embodiment, an implementation of the elastic structure is provided, which is as follows:

[0056] The elastic structure includes a spring 8, which is fixed on the base 1 and located on one side of the material carrying platform 2;

[0057] The bracket 3 is provided with a fixed pulley 35 , and the fixed pulley 35 is provided with a pull wire 34 . One end of the pull wire 34 is fixedly connected to the spring 8 , and the other end thereof is fixedly connected to the material carrying platform 2 .

[0058] Spring 8 exerts an upward force on material platform 2 via pull wire 34, causing it to rise to a certain height. Conversely, as the weight on material platform 2 increases, it lowers accordingly. In this way, material platform 2 automatically maintains a relatively stable height under varying loads, significantly reducing the need for operators to frequently bend or reach to adjust the height of material platform 2.

[0059] In practical applications, the spring 8 can be removed from the base 1, so different springs 8 can be replaced for different occasions. That is, by changing the tension of the spring 8 on the pull wire 34, the height of the material carrying platform 2 in the natural state can be changed.

[0060] When the material stacking height on the material supporting platform 2 is too high and the weight of the placed materials is greater than the tension of the spring 8, the height of the supporting platform will automatically drop. When part of the material is used and the weight of the materials on the material supporting platform 2 is less than the tension of the spring 8, the height of the supporting platform will automatically rise, so that the height of the materials on the material supporting platform 2 is always level with the waist of the operator, and the operator does not need to bend over frequently to operate.

[0061] In a preferred embodiment of this embodiment, the fixed pulley 35, the pull wire 34, and the spring 8 form a tension-providing group. Two tension-providing groups are provided, and the two tension-providing groups are symmetrically arranged about the center of the material carrier 2. The fixed pulley 35 is used to change the direction of the action of the spring 8. In actual applications, two fixed pulleys 35 can be provided in each tension-providing group, and the axes of the two fixed pulleys 35 are parallel.

[0062] By using two symmetrically arranged tensioning force providing groups, the material carrying platform 2 can maintain better stability and balance during the lifting process. Even in the case of uneven load distribution, it can effectively prevent the material carrying platform 2 from tilting or shifting, thereby ensuring the safety and accuracy of the handling process.

[0063] Example 3

[0064] like Figures 1-8 As shown, this embodiment is improved on the basis of embodiment 1. The difference between this embodiment and embodiment 2 is that there is no need to set a fixed pulley 35 and a pull rope, and the spring 8 is directly set below the material carrying platform 2. Specifically:

[0065] In this embodiment, the elastic structure includes an elastic support member 9, which is provided on the base 1 and located below the material carrying platform 2. The elastic support member 9 is connected to the top of the material carrying platform 2. The elastic support member 9 of the present application can be a hydraulic rod.

[0066] In this embodiment, the elastic support member 9 is disposed below the material carrying platform 2 , thereby applying an upward force to the material carrying platform 2 , so that the material carrying platform 2 is maintained at a suitable height.

[0067] In a preferred embodiment of this embodiment, the base 1 may also be provided with a drive device, such as a pneumatic cylinder, for driving the material carrier 2 up and down. When the material carrier 2 needs to be maintained at a suitable height, the elastic support member 9 exerts an upward force on the material carrier 2 through its own elastic force. This force is balanced by the gravity of the material carrier 2 and the material on it, thereby ensuring that the material carrier 2 remains stable at the appropriate height. When the material carrier 2 needs to be raised or lowered, the drive device can be used to adjust the degree of compression of the elastic support member 9, thereby achieving the desired elevation.

[0068] Example 4

[0069] This embodiment is improved on the basis of embodiment 1.

[0070] In this embodiment, the bracket 3 is further refined.

[0071] like Figures 1-8As shown, the bracket 3 includes at least one support rod 31 and at least one first guide rod 32. The support rod 31 and the first guide rod 32 are both fixed to the base 1. The first guide rod 32 is located on one side of the support rod 31. The first guide rod 32 is connected to the support rod 31 through a connecting plate 33.

[0072] A first sliding sleeve 36 is provided on one side of the material carrying platform 2 , and the first sliding sleeve 36 is sleeved on the first guide rod 32 .

[0073] In actual applications, two support rods 31 and two first guide rods 32 are provided, and the support rods 31 and the first guide rods 32 are provided in pairs.

[0074] By providing the first guide rod 32 and the sliding sleeve structure, the stability of the material carrier 2 during the lifting process is significantly improved. The guide rod provides a clear lifting path for the material carrier 2, effectively preventing it from shifting or shaking during the lifting process. The support rod 31 and the first guide rod 32 are connected by a connecting plate 33, which enhances the overall rigidity and deformation resistance of the bracket 3. Specifically, the connecting plate 33 is screwed to the support rod 31 and the first guide rod 32. This structural design enables the bracket 3 to withstand greater loads and longer use, thereby extending the service life of the material lift truck.

[0075] Example 5

[0076] This embodiment is improved on the basis of embodiment 1.

[0077] In this embodiment, an implementation of the base 1 is provided.

[0078] like Figures 1-8 As shown, specifically, the base 1 includes a mounting frame 11, and the bracket 3 is fixed on the mounting frame 11; the mounting frame 11 is a main component of the base 1, provides support for the entire transport vehicle, and is provided with a structure for fixing the bracket 3.

[0079] A plurality of connecting rods 12 are disposed in the installation frame 11 , and the plurality of connecting rods 12 are disposed in parallel in the installation frame 11 .

[0080] In actual application, the installation frame 11 is made of lean pipe. The size of the installation frame 11 can be adjusted according to actual needs.

[0081] By providing the connecting rods 12, the mounting frame 11 of the base 1 forms a more stable grid structure, effectively improving the structural stability of the entire vehicle. This design allows the material lift truck to maintain a stable posture when carrying heavy objects, reduces safety hazards caused by equipment shaking, and also allows the material lift truck to withstand greater loads.

[0082] Example 6

[0083] This embodiment is improved on the basis of embodiment 1.

[0084] like Figures 1-8 As shown, in this embodiment, each connecting rod 12 is provided with a mounting groove 122 , and the mounting groove 122 is provided along the length direction of the connecting rod 12 . A plurality of rollers 121 are provided in the mounting groove 122 .

[0085] The connecting rod 12 can be used to carry cargo, while the rollers 121 facilitate adjustment of cargo's position on the base 1, improving cargo handling efficiency. In actual use, the connecting rod 12 is constructed from a high-strength, lightweight alloy to ensure strength and durability when carrying heavy cargo, while also reducing the overall system weight for easier handling and installation. Furthermore, the rollers 121 feature a non-slip texture to increase friction between the rollers 121 and the cargo, reducing sway during handling and improving safety.

[0086] When cargo is placed on base 1, its bottom contacts rollers 121. The position and number of rollers 121 can be adjusted based on the size and weight of the cargo to ensure stable support. Workers can adjust the cargo's position on base 1 by pushing or pulling the connecting rods 12. The presence of rollers 121 allows for easy adjustments without lifting the entire cargo, improving handling efficiency and safety. This design is particularly suitable for situations where frequent adjustments to cargo position are required or for handling irregularly shaped cargo.

[0087] In a more preferred embodiment of this embodiment, a connecting frame 14 is provided at opposite ends of each connecting rod 12. The connecting frame 14 is provided with a clamping slot 141. The clamping slot 141 is adapted to the mounting frame 11. The connecting rod 12 is clamped to the mounting frame 11 through the engagement between the clamping slot 141 and the mounting frame 11. Due to the clamping engagement between the clamping slot 141 and the mounting frame 11, the position of the connecting rod 12 can be flexibly adjusted as needed.

[0088] Specifically, cargo carrying positions are formed between the connecting rods 12 , and the positions of the connecting rods 12 on the mounting frame 11 can be adjusted by the cooperation between the connecting frame 14 and the mounting frame 11 to adapt to the placement requirements of cargo of different sizes.

[0089] In actual use, based on the size and shape of the cargo, the staff first determines the optimal position of the connecting rod 12 on the mounting frame 11, and then aligns the slot 141 of the connecting rod 12 with that on the mounting frame 11 to fix the connecting rod 12 to the mounting frame 11. In addition, the slot 141 and the mounting frame 11 can be locked to each other with screws. In cases where multiple pieces of cargo or large cargo need to be placed, multiple connecting rods 12 may be required to work together. The staff can adjust the positions of multiple connecting rods 12 at the same time according to the layout of the cargo to ensure the stability and handling efficiency of the entire cargo. The design of the connecting rod 12 and the mounting frame 11 makes the base 1 highly flexible and scalable. It can adapt to the carrying of cargo of different sizes and weights.

[0090] Example 7

[0091] This embodiment is improved on the basis of embodiment 1.

[0092] like Figures 1-8 As shown, in this embodiment, a second guide rod 13 is provided in the mounting frame 11, a second sliding sleeve 4 is sleeved on the second guide rod 13, a mounting frame 5 is provided on the second sliding sleeve 4, a control handle 6 is provided on the mounting frame 5, and the control handle 6 is hinged to the mounting frame 5.

[0093] Specifically, the second sliding sleeve 4 can slide on the second guide rod 13, so the position of the second sliding sleeve 4 can be adjusted during use to change the position of the control handle 6, so that the movement of the transport vehicle can be controlled from different directions.

[0094] The control handle 6 is used to control the movement of the entire transporter. The hinged design between the control handle 6 and the mounting frame 5 allows the operator to freely adjust the angle and position of the handle within a certain range to adapt to different operating habits and working environments, which can improve the flexibility of the transporter control.

[0095] In actual application, the handle portion of the control handle 6 is designed to be retractable, and the operator can adjust the length of the handle by rotating or sliding the mechanism. This design allows operators of different heights to find an operating position that suits them, thereby improving the comfort of operation.

[0096] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0097] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0098] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
