Description

Technical Field

[0001] The present invention relates to the technical field of cargo transportation equipment, and in particular to a transportation device with adjustable cargo position. Background Art

[0002] In the automotive industry, the storage and transportation of parts are important components of the production process. In the process of vehicle production in the automotive industry, a single production line will produce multiple models, and different models and configurations will be produced continuously. The types and quantities of parts required for different models and configurations are also different, and the sizes of some parts also vary. In order to ensure production efficiency and part quality, it is necessary that during the transportation of parts, the transportation equipment must meet the characteristics of different parts.

[0003] In the prior art, the cargo space of the transport equipment is fixed and mainly consists of two parts. The first part of the cargo space is fixed with a flat plate to place the parts transport boxes, which are divided into large and small sizes. Transport boxes that do not meet these two sizes need to be subcontracted, making the parts transportation procedure more complicated; the second part of the cargo space is arranged in a pocket grid, mainly for placing single parts with protection requirements, and the grid size is divided into large and small. Therefore, this type of transport equipment can only transport parts of four models (corresponding to four sizes).

[0004] There are many types of transport equipment in the existing technology. Different equipment is used according to the different models and configurations of the production line. Therefore, the number of equipment required increases, which will occupy a large amount of logistics space, increase management difficulty and maintenance costs. The subcontracting process of transport boxes increases the operation links and poses quality risks. If large-sized parts need to be transported, adjacent models and configurations can only use large-grid-sized transport equipment. Large-grid-sized equipment transports small-sized parts, which results in a decrease in the number of transport equipment and an increase in the frequency of transportation.

[0005] Identification management is also an indispensable part of the storage and transportation of parts. Traditional identification methods often use labels or identification cards to mark part information, but this physical contact method can easily cause labels to fall off or be lost, increasing the difficulty of finding and managing.

[0006] There is currently no effective solution to the above problems. Summary of the invention

[0007] The main purpose of the present invention is to provide a transport device with adjustable cargo space, so as to solve the problem in the prior art that the space of the transport equipment is not fully utilized during the transportation process due to the fixed cargo space of the transport equipment.

[0044] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0045] Combination Figures 1 to 4 As shown, according to a specific embodiment of the present application, a transport device with adjustable cargo space is provided.

[0046] Specifically, the transport device comprises: a three-dimensional frame 1 and a cargo space size adjustment mechanism. The three-dimensional frame 1 has a storage space; the cargo space size adjustment mechanism comprises at least one slide bar group 2, the slide bar group 2 is connected to the three-dimensional frame 1, and the slide bar group 2 divides the storage space into at least two cargo spaces 3. The slide bar group 2 and the three-dimensional frame 1 are relatively slidable along a first direction, so that the size of each cargo space 3 can be adjusted. The first direction is along the length direction of the three-dimensional frame 1.

[0047] By applying the technical solution of the present invention, the slide bar group can slide relative to the three-dimensional frame, and the space in the frame can be flexibly divided into multiple cargo spaces with adjustable sizes by sliding, so as to achieve effective carrying and flexible adjustment of parts and transport boxes of different specifications. By using this transport device, the size of the cargo space can be dynamically adjusted according to the size of the parts, thereby avoiding the problem of space waste caused by only selecting the transport equipment according to the largest size part when transporting parts of different sizes. The dynamic displacement of the slide bar group can adapt to the transportation needs of parts of various sizes, so as to solve the problem of insufficient space utilization of the transport equipment during transportation due to the fixed cargo space in the prior art.

[0048] Specifically, there are multiple slide bar groups 2, and the multiple slide bar groups 2 are arranged at intervals along the first direction. A cargo space 3 is formed between adjacent slide bar groups 2, and a cargo space 3 is formed between the slide bar groups 2 and the three-dimensional frame 1. The size of the cargo space 3 will change with the movement of the slide bar groups 2, and the cargo space 3 can be flexibly adjusted to better meet the transportation needs of different parts.

[0049] like Figure 3 As shown, in this embodiment, a total of 4 groups of slide bar groups 2 are arranged, which are arranged at intervals along the first direction. The intervals between the slide bar groups 2 can be different, and adaptive adjustment can be performed according to the size of the transported parts. In this embodiment, by setting the slide bar group 2 to be movable forward and backward, the size of the cargo space 3 can be adjusted according to the size of the parts or transport boxes to be loaded. This independent adjustment function allows the sizes of the cargo space 3 on the front and rear sides to be different, so that parts with large differences in front and back sizes can be handled, thereby improving space utilization. The size of the cargo space 3 on the front and rear sides can be determined by the position of the slide bar group 2 closest to the front side of the three-dimensional frame 1. In actual applications, the cargo space 3 can be adjusted to a form of wide front and narrow rear or narrow front and wide rear according to the size of the parts, which can more effectively fix the transport boxes or parts, reduce displacement during transportation, ensure the safety of the transportation process, and reduce possible damage.

[0050] Specifically, at least one slide bar group 2 includes two slide bars 21, and the two slide bars 21 are respectively arranged on both sides of the three-dimensional frame 1 along the second direction, and the second direction is the height direction along the three-dimensional frame 1. The first end of the slide bar 21 is slidably connected to the top of the three-dimensional frame 1, and the second end of the slide bar 21 is slidably connected to the bottom of the three-dimensional frame 1. The slide bars 21 are arranged along both sides of the three-dimensional frame 1, and can maintain good stability during the adjustment process through the sliding connection between the top and the bottom. This design can prevent the slide bars from accidentally tilting or loosening during transportation or size adjustment, and ensure the safety of loaded parts. The slide bars 21 can be adjusted on both sides of the three-dimensional frame 1, and the operator can conveniently adjust the size of the cargo space 3 at different angles and positions without going around to the other side of the transportation device, thereby improving work efficiency.

[0051] Specifically, a first sliding rail 11 extending in a first direction is provided at the top of the three-dimensional frame 1, and a first end of the sliding rod 21 is connected to the first sliding rail 11, and / or a second sliding rail 12 extending in the first direction is provided at the bottom of the three-dimensional frame 1, and a second end of the sliding rod 21 is connected to the second sliding rail 12. The sliding connection between the sliding rod 21 and the first sliding rail 11 and the second sliding rail 12 enables the sliding rod 21 to move smoothly on the sliding rails, thereby realizing the adjustment of the cargo space 3. This design allows the transport tool to adjust the width or depth of the cargo space according to the specific size requirements of the loaded parts or boxes to accommodate items of different sizes and improve space utilization efficiency.

[0052] like Figure 1 As shown, in this embodiment, the first sliding guide rail 11 and the second sliding guide rail 12 are respectively arranged on both sides of the three-dimensional frame, with a total of 4 rails in the upper and lower, left and right directions. The guide rails are designed to be convex and mainly play a guiding and supporting role, ensuring that the slide rod 21 moves smoothly along the predetermined path during the adjustment process, avoiding deviation or jamming during the movement, and ensuring the structural stability of the entire transport equipment and the smoothness of operation.

[0053] Optionally, the slide bar 21 is connected to the first sliding guide rail 11 and the second sliding guide rail 12 through a roller mechanism 15, each roller mechanism 15 is composed of two U-shaped rollers, and each slide bar 21 has two rollers on the upper and lower sides, forming a four-concave roller group, and the rollers are installed on the slide bar 21 through an axis, and the axis is usually perpendicular to the slide bar 21. The rollers rotate around the axis to ensure that the rollers can slide along the guide rail direction. The design of the four-concave roller group can effectively fit closely with the surface of the convex guide rail, increase the contact area and friction, and reduce the position change of the slide bar 21 caused by vibration or external force during transportation, thereby improving the stability and carrying capacity of the slide bar 21 when moving on the guide rail. The matching design of the U-shaped roller and the convex guide rail can effectively prevent foreign objects from getting stuck. Even on uneven ground or with small obstacles, the rollers can continue to slide smoothly and will not be easily stuck by foreign objects on the ground, reducing the need for maintenance and cleaning. The roller is made of nylon, which has good wear resistance and self-lubricating properties. It can ensure the smoothness and low noise of the roller when sliding on the guide rail, while also reducing the wear on the guide rail and improving the practicality and durability of the transport device.

[0054] Specifically, at least one end of at least one slide bar 21 is provided with a locking assembly 4, and the locking assembly 4 has a locking state for locking the slide bar 21 at the current position, and an unlocking state for releasing the slide bar 21 so that the slide bar 21 and the three-dimensional frame 1 can slide relative to each other. The locking assembly 4 can lock the slide bar 21 after the slide bar 21 is adjusted to a suitable position, thereby locking the position of the slide bar 21, ensuring that the slide bar will not be displaced due to external force or vibration during transportation, ensuring the stability of the internal parts and material boxes of the transport equipment, and preventing possible damage to the goods during logistics operations. When installing parts, the locking assembly 4 is released to the unlocking state, and the slide bar 21 is moved according to the specific size of the parts, thereby making rational use of space.

[0055] Specifically, the three-dimensional frame 1 includes a fixed rod 13 extending along the first direction, and the locking assembly 4 includes: a foot pedal 41 and a second-order self-locking device 42, the foot pedal 41 is connected to the slide bar 21; the second-order self-locking device 42 is connected to the slide bar 21, and the second-order self-locking device 42 is connected to the foot pedal 41, the second-order self-locking device 42 has an ejection position in which the internal ejector rod is extended to a preset position, and the second-order self-locking device 42 has a retracted position in which the ejector rod is retracted, and the second-order self-locking device 42 can be operated to switch between the ejection position and the retracted position. When the second-order self-locking device 42 is in the ejection position, the ejector rod abuts against the fixed rod 13, so that the locking assembly 4 is in an ascending locking state. By stepping on the foot pedal 41 to switch the second-order self-locking device 42 between the ejection position and the retracted position, the position of the slide bar 21 is accurately controlled and safely locked, ensuring the stability and safety of the transport equipment in different operating environments, while simplifying the operating process and improving the efficiency of logistics operations.

[0056] like Figure 1 As shown, the fixing rod 13 is located below the slide bar 21 and connected to the locking assembly 4. The three-dimensional frame 1 is provided with two fixing rods 13 respectively arranged on both sides of the three-dimensional frame 1 along the first direction, and connected to the corresponding positions of the three-dimensional frame 1 by welding or other means to increase the stability of the three-dimensional frame 1. The fixing rod 13 provides an additional fixing point for the slide bar 21, which helps the slide bar 21 to move smoothly on the first sliding guide rail 11 and the second sliding guide rail 12. At the same time, after the slide bar 21 is adjusted to the desired position, the position of the slide bar 21 is locked through the cooperation of the locking assembly 4 and the fixing rod 13, ensuring that the size of the cargo space 3 will not change during transportation, thereby ensuring transportation safety. In this embodiment, the fixing rod 13 is generally made of a material such as 40*20*2mm square steel. This steel has good strength and rigidity, is suitable for use as a reinforcement and support component, and is also easy to process and install.

[0057] like Figure 2 As shown, the foot pedal 41 is designed as a flat structure that is easy to operate. It is usually made of metal or composite materials and has sufficient strength and rigidity to withstand the pedaling force of the operator. The foot pedal 41 is connected to the second-order self-locking device 42 through a hinge or other types of connectors to ensure that the pedaling action can be directly transmitted to the control mechanism of the second-order self-locking device 42. In order to improve the safety and comfort of operation, anti-slip textures can be provided on the foot pedal 41 to prevent the operator from slipping during the pedaling process.

[0058] Optionally, the second-stage self-locking device 42 is a mechanical mechanism with a two-stage locking function, including two stages of locking and unlocking. It is usually composed of components such as a lock pin, a spring, and a push rod.

[0059] like Figure 2As shown, the second-order self-locking device 42 is connected to the slide bar 21 and the foot pedal 41. In the initial state, the second-order self-locking device 42 is in a locked state, and the locking pin inside it is connected to the slide bar. At this time, when the second-order self-locking device 42 is in the ejected position, the ejector rod abuts against the fixed rod 13 to put the locking assembly 4 in an ascending locked state, and fix the slide bar 21 by a certain friction force or mechanical force to prevent it from moving on the guide rail. When the operator needs to adjust the size of the cargo space 3, the operator steps on the pedal 41 connected to the second-order self-locking device 42, and the downward force of the pedal 41 is transmitted to the top rod inside the second-order self-locking device 42 through the connecting mechanism. The top rod is retracted to the retracted position by the external force, so that the locking relationship between the slide bar 21 and the second-order self-locking device 42 is released. At this time, the slide bar 21 can slide freely on the guide rail along the first direction and adjust to the required cargo space 3 size. When the slide bar 21 is adjusted to the right position, the operator steps on the pedal 41 again. At this time, the spring returns to its original state, so that the second-order self-locking device 42 switches from the retracted position to the ejection position, and the top rod abuts against the fixed rod 13, so that the slide bar 21 is re-locked, ensuring the stability of the cargo size during transportation. The cooperation between the second-order self-locking device 42 and the pedal 41 makes the locking and unlocking operations of the slide bar 21 safer. Even if it encounters bumps or impacts during transportation, the slide bar 21 can remain in the predetermined position, greatly reducing the risk of parts being damaged due to changes in the size of the equipment during transportation. The operator can unlock and lock the slide bar 21 simply by stepping on the pedal 41. The operation steps are simple, which improves the efficiency of logistics operations. This design avoids the cumbersome process of manually adjusting and fixing the slide bar 21, saving operation time.

[0060] Specifically, along the first direction, a first cargo space 31 for placing a material box is formed between a slide bar group 2 among the multiple slide bar groups 2 close to the three-dimensional frame 1 and the three-dimensional frame 1, and a plurality of material box mounting plates 22 are provided on the side of the slide bar group 2 facing the three-dimensional frame 1. The plurality of material box mounting plates 22 are spaced apart along the height direction of the slide bar group 2, and the material box mounting plates 22 divide the first cargo space 31 into a plurality of material box mounting spaces along the height direction.

[0061] like Figure 3As shown, the first cargo space 31 is located on the left side of the transport device. In this embodiment, three material box mounting plates 22 are arranged at intervals along the height direction of the slide bar group 2. One end of the material box mounting plate 22 is fixed to the three-dimensional frame 1, and the other end of the material box mounting plate 22 is fixed to the slide bar 21. The three material box mounting plates 22 divide the first cargo space 31 into four cargo layers. The first cargo space 31 is adjusted by the slide bar 21. Each layer can be changed from placing one material box to placing multiple material boxes, thereby increasing the number of parts placed and improving efficiency. The upper surface of the material box mounting plate 22 is covered with a layer of EVA strips. The EVA strips have excellent flexibility, elasticity and wear resistance, which enables it to adapt well to transport boxes of different sizes and shapes. When the size of the first cargo space 31 is adjusted, the EVA strips can make adaptive changes according to the adjusted size, effectively fix the transport box, and prevent displacement or vibration during transportation. The installation of the EVA strip is also relatively simple, and can be fixed on the material box mounting plate 22 by adhesive, rivets or screws, etc., to provide a stable support for the transport box. The EVA material is light and will not increase the weight of the material box mounting plate 22, thereby reducing the total weight of the transport device and improving the handling efficiency.

[0062] Specifically, a second cargo space 32 for placing a single part is formed between adjacent slide rod groups 2, and a plurality of bearings are connected between adjacent slide rod groups 2. The plurality of bearings are arranged at intervals along the height direction, and the bearings divide the second cargo space 32 into a plurality of part installation spaces along the height direction. The bearings are elastically arranged, and the bearings are used to carry parts. By dividing the second cargo space 32 by elastic bearings, multi-layer and flexible storage of a single part along the height direction is achieved, space utilization and part protection are improved, and loading adaptability and transportation efficiency are enhanced.

[0063] like Figure 3 As shown, the second cargo space 32 is located on the right side of the transport device. It can be seen that the second cargo space 32 is divided into 4 groups by 4 groups of slide rod groups 2 and the three-dimensional frame 1. Multiple bearings are connected between adjacent slide rod groups 2, and the space between every two slide rod groups 2 is divided into 4 layers, with a total of 16 cargo spaces, which increases the number of parts placed and improves efficiency. The 4 groups of cargo spaces can adjust the cargo space size through adjacent slide rod groups 2, so that the transport device can adapt to parts of different sizes, reduce the links that require additional processing due to mismatched part sizes, and improve the efficiency of logistics operations.

[0064] Specifically, the bearing member is a connecting cloth, which is made of canvas material, which is not only light but also has certain strength and durability, and can bear the weight of the parts and provide sufficient support.

[0065] Optionally, in this embodiment, the cargo space 3 is divided into a first cargo space 31 and a second cargo space 32, and the design of the first cargo space 31 and the second cargo space 32 can adapt to goods of different sizes and types. The first cargo space 31 is usually designed as a larger, adjustable space, suitable for placing larger parts or transport boxes, while the second cargo space 32 is relatively small, which can more accurately fix and protect smaller parts or transport boxes. This layered space design can ensure that when facing goods of various sizes, the operator can flexibly adjust the size and layout of the cargo space according to the actual size and shape of the goods, and can more efficiently utilize the internal space without changing different transport equipment to meet various transportation needs. The design of the first cargo space 31 and the second cargo space 32 can easily classify and manage the goods, and each space can carry a specific type or size of goods, which simplifies the cargo classification and loading process in logistics operations. At the same time, the independence and adjustability of each space also facilitate the maintenance and modification of the transport equipment, and improve its economy and practicality in long-term use.

[0066] Furthermore, the transport device further comprises a door curtain 5, which is movably connected to the three-dimensional frame 1, and has an unfolded position for shielding at least a portion of the three-dimensional frame 1 along the circumference of the three-dimensional frame 1, and a folded position for rolling up to a preset space. In this device, the door curtain 5 mainly plays a protective role, improving the functionality and durability of the entire transport device.

[0067] like Figure 3 As shown, the door curtain 5 is installed on the front side of the transport device. The door curtain 5 can only block the second cargo space 32, or completely block the front side of the transport device, depending on actual needs. The door curtain 5 is movably connected to the three-dimensional frame 1. It can be considered that the door curtain 5 can be pulled to move along the first direction of the three-dimensional frame 1. The door curtain 5 can be switched between the unfolded position and the folded position at will. For a single part cargo space, the door curtain 5 added in front of each cargo space is designed with a sloped bottom surface, which can effectively prevent the parts from falling due to shaking or sudden braking during transportation. The sloped design uses gravity to make the parts naturally tilt inward, increasing the safety factor.

[0068] It is necessary to further explain that in this embodiment, the door curtain 5 is made of canvas material, which is both durable and dustproof and breathable, suitable for use in industrial logistics environments, and can effectively prevent external dust and foreign objects from entering the interior of the transport equipment, while not being completely closed, maintaining a certain degree of ventilation, and preventing the internal temperature from being too high or the humidity from being too high to cause damage to the parts. Adding a flannel protective layer on the inside of the door curtain 5 can further protect the parts from external factors, especially for single parts with protection requirements, the flannel layer can reduce friction and collision, and reduce scratches and wear on the surface of the parts.

[0069] It should be further explained that the transport device also includes a fork sleeve 14 and a shock-absorbing wheel 7 .

[0070] like Figure 4 As shown, there are 4 shock-absorbing wheels 7, the two front wheels of the transport device are universal wheels, and the two rear wheels are fixed wheels. The setting of the front universal wheels provides the flexibility of 360-degree rotation, which is convenient for steering in a small space or complex environment, and improves the maneuverability of the transport device, while the fixed wheels at the rear maintain the stability of the transport direction, reduce the shaking during non-linear motion, and ensure straight-line travel during transportation. The 4 shock-absorbing wheels 7 are all equipped with foot brakes. The setting of the foot brake improves the convenience and safety of operation, can brake quickly when needed, can stably stop the transport device, and ensure stability during loading and unloading and static. The shock-absorbing wheel 7 usually adopts a hub design with shock-absorbing materials, such as elastic rubber or polymer materials, to absorb the impact caused by uneven ground, thereby improving stability and safety during transportation.

[0071] The fork sleeve 14 is located at the bottom of the transport device. The fork sleeve 14 is a U-shaped structure welded to the lower frame of the three-dimensional frame 1. Two fork sleeves 14 are arranged at intervals along the first direction of the transport device. The fork sleeve 14 is made of metal material and has sufficient strength and stability to withstand the mechanical force when the forklift is inserted. The shape and size of the fork sleeve 14 need to meet the standard size of the forklift inserting teeth to ensure that the forklift can smoothly and safely insert and carry the transport device. By setting the fork sleeve 14, the operator can quickly use the forklift to move the transport device without manual handling, reducing labor costs and operation time.

[0072] It needs to be further explained that if Figure 1 , Figure 4 As shown, the three-dimensional frame 1 is the basic structure of the transport device of the present invention, which is composed of 12 square steels of 40x40x2mm, 7 square steels are reinforced on the upper and lower sides, and 2 square steels are reinforced on the left and right sides. The whole is assembled by welding to form a stable three-dimensional structure. The three-dimensional frame 1 also includes: a first traction component 6, a second traction component 8, a protection mechanism 9 and an identification card frame 10.

[0073] The protection mechanism 9 is constructed of a 2 mm thick iron plate and wrapped around the upper side, front side, rear side, left side and right side of the transport device, effectively preventing dust pollution and providing protection for the parts in transport.

[0074] On the left and right sides of the protection mechanism 9 on the front side of the three-dimensional frame 1, there are identification card frames 10, with the equipment identification card placed on the left side and the parts identification card placed on the right side for easy identification and management. The identification card frame 10 is made of weather-resistant material. The use of weather-resistant material ensures the durability of the identification card frame 10 in various harsh environments and extends its service life. When transporting auto parts outdoors or under extreme weather conditions, the weather-resistant identification card frame 10 can clearly display part information and improve the accuracy and efficiency of transportation.

[0075] The first traction assembly 6 and the second traction assembly 8 are respectively arranged on the protective mechanism on the front and rear sides. In this embodiment, the first traction assembly 6 and the second traction assembly 8 both adopt traction hooks, and the traction hooks can be provided with an anti-drop locking device. The anti-drop locking device ensures the safety and reliability of the traction process and prevents accidental detachment during transportation. The first traction assembly 6 is used to connect another transport device to form a transport chain, or is used when force needs to be applied from the rear. The second traction assembly 8 is arranged at the front of the transport device and can be hooked by other equipment with traction devices (such as trailers and tractors) to drag the entire transport device. The first traction assembly 6 and the second traction assembly 8 usually use finished parts, and the traction hooks are designed with a safety locking structure to ensure stability and safety during the traction process. The first traction assembly 6 and the second traction assembly 8 are made of high-strength stainless steel and are designed to be rotatable. The high-strength stainless steel material and the rotatable design enhance the traction capacity and flexibility and adapt to the traction requirements in different directions. In the multi-directional transportation and handling of automotive parts, this design can improve the flexibility and efficiency of operation and reduce the inconvenience caused by direction adjustment.

[0076] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0077] 1. The transport device can adjust the size of the cargo space according to the needs by making the slide bar group slide on the first sliding rail and the second sliding rail in the first direction, and lock and unlock the slide bar through the cooperation of the second-order self-locking device and the foot pedal to ensure the stability of the cargo space size during transportation. Thus, the original four fixed-size transport tools are replaced by a single adjustable tool, which significantly reduces the types and quantities of tools required, simplifies logistics management, and saves maintenance costs and storage space.

[0078] 2. The cargo space is divided into a first cargo space and a second cargo space. The first cargo space 31 is divided into multiple cargo spaces along the height direction by the material box mounting plate, and the second cargo space 32 is divided into multiple parts installation spaces along the height direction by the bearing member. By dividing the cargo space into two parts, it is possible to efficiently load parts of various sizes on the same transport vehicle, greatly improving space utilization and unit transportation efficiency.

[0079] 3. The height of each cargo position of the transport device is designed from the perspective of ergonomics. The operator moves the slide bar by stepping on the foot pedal, and locks the slide bar after moving it to the corresponding position. A fork sleeve is set at the bottom of the transport device to facilitate forklift operation, reduce the degree of bending and lifting of operators during operation, and reduce the operating burden of operators.
