Description

Technical Field

[0001] This application relates to the technical field of cargo transportation, and in particular to a stackable and connectable sheet metal transport vehicle. Background Technology

[0002] In fields such as machinery manufacturing and sheet metal processing, the turnover and temporary storage of sheet metal parts are common needs. Currently, the common method is to use metal hand-pushed transport carts to transfer sheet metal parts.

[0003] A typical transport vehicle generally includes a base, casters, and a U-shaped pusher frame. The base is used to place sheet metal parts, and the casters are located below the base to move the transport vehicle. The pusher frame is hinged to one end of the upper surface of the base via a hinged joint. When in use, the pusher frame is rotated to a vertical position to push the transport vehicle; when not in use, the handle can be rotated and folded back into the base.

[0004] Because the capacity of a single transport vehicle is limited, multiple transport vehicles need to be used simultaneously to transport goods; therefore, factories generally need a large number of transport vehicles. However, due to structural limitations, transport vehicles in related technologies cannot be effectively stacked when idle, and a large number of empty vehicles will occupy a lot of warehouse space. Utility Model Content

[0005] To reduce the space occupied by transport vehicles when they are idle, this application provides a stackable and connectable sheet metal transport vehicle.

[0006] This application provides a stackable and connectable sheet metal parts transport vehicle, which adopts the following technical solution: A stackable and connectable sheet metal parts transport vehicle includes a base plate, a plurality of pulleys disposed below the base plate, a pusher frame rotatably disposed on the base plate, and four connecting rods disposed at the four corners of the base plate; The upper end of the connecting rod extends upward beyond the upper surface of the base plate, and the lower end of the connecting rod extends downward and is provided with a sleeve block. The lower surface of the sleeve block is provided with a connecting groove for the connecting rod to be inserted. The lower surface of the pulley is lower than the lower surface of the sleeve block. When the connecting rod is inserted into the connecting slot of the upper block of the adjacent transport vehicle, a storage space is formed between the bottom plates of the two adjacent transport vehicles, and the several pulleys and the rotating and folding push frame can be stored in the storage space.

[0007] By adopting the above technical solution, when transporting sheet metal parts, the base plate can be used to place the sheet metal parts, the pulleys drive the transport vehicle to move, and the hand-push frame is used to push the transport vehicle. When idle, the connecting rod can be inserted into the connecting groove of the sleeve block on the adjacent transport vehicle, so that a storage space is formed between the base plates of the two adjacent transport vehicles. At the same time, the pulleys and the rotating and folded hand-push frame can be stored in this space, realizing the stacking and storage of transport vehicles and reducing the warehouse space occupation.

[0008] Optionally, the pusher includes two parallel first rods and a plurality of second rods connected between the two first rods, with the lower ends of the first rods rotatably connected to the base plate.

[0009] By adopting the above technical solution, the hand-pushing frame adopts a structure of two parallel first rods and several second rods connected between the two first rods, and the lower end of the first rod is rotatably connected to the base plate. This makes it convenient for users to push the transport vehicle, and also allows the hand-pushing frame to rotate, meeting the needs of rotating to a vertical position to push the transport vehicle when in use, and rotating and folding it into storage on the base plate when not in use.

[0010] Optionally, the upper end of the connecting rod is provided with a mounting groove, the lower end of the first rod is rotatably connected to the connecting rod, and the first rod can be rotated and folded towards the base plate; the connecting rod is provided with a mounting part for connecting the first rod, and a limiting part that can restrict the rotation of the first rod when the push frame is in use.

[0011] By adopting the above technical solution, an installation groove is opened at the upper end of the connecting rod so that the lower end of the first rod can be rotatably connected to the connecting rod. The first rod can be rotated and folded towards the base plate, which is convenient for storing the push frame when the transport vehicle is not in use. The mounting part is used to connect the first rod and the connecting rod to ensure the connection stability between the push frame and the base plate. The limiting part can restrict the rotation of the first rod when the push frame is used to ensure that the push frame is in a stable working state.

[0012] By adopting the above technical solution, an installation groove is opened at the upper end of the connecting rod so that the lower end of the first rod can be rotatably connected to the connecting rod. The first rod can be rotated and folded towards the base plate, which is convenient for storing the push frame when the transport vehicle is not in use. The mounting part is used to connect the first rod and the connecting rod to ensure the connection stability between the push frame and the base plate. The limiting part can restrict the rotation of the first rod when the push frame is used to ensure that the push frame is in a stable working state.

[0013] Optionally, the mounting components are mounting bolts and mounting nuts, and the connecting rod has a first hole for the mounting bolt to pass through, and the first rod has a second hole for the mounting bolt to pass through.

[0014] By adopting the above technical solution, using mounting bolts and mounting nuts as mounting components, and cooperating with the first hole on the connecting rod and the second hole on the first rod, the rotational connection between the first rod and the connecting rod is realized, ensuring that the push frame can rotate normally. At the same time, the structure is simple, easy to install and disassemble, and convenient for the maintenance and replacement of parts of the transport vehicle.

[0015] Optionally, the limiting member includes limiting rods disposed on both sides of the first rod and a third hole disposed on the upper surface of the connecting rod; both the first hole and the third hole extend vertically in an oblong shape, the mounting bolt can slide up and down in the first hole, and the limiting rod can slide up and down in the third hole; when the mounting bolt abuts against the upper surface of the first hole, the limiting rod moves upward and disengages from the third hole; when the mounting bolt abuts against the lower surface of the first hole, the limiting rod engages in the third hole.

[0016] By adopting the above technical solution, the mounting bolts and the limiting rod can be slid up and down using the first and third holes of the waist shape. The limiting rod can be easily controlled to engage or disengage from the third hole, thereby flexibly restricting or releasing the restriction on the rotation of the first rod, ensuring the stability of the push frame in use and the convenience of folding and storing it.

[0017] Optionally, the pusher is provided at both ends of the base plate.

[0018] By adopting the above technical solution, the bottom plate of the stackable and connectable sheet metal parts transport vehicle has push frames at both ends, which allows the transport vehicle to be pushed in both the front and rear directions. During the transportation process, the operator can flexibly choose the pushing direction according to the actual situation, thereby improving the convenience of transportation operation.

[0019] Optionally, a connecting device is also included. When the transport vehicle is used to transport goods, the connecting device can connect two adjacent transport vehicles. When the transport vehicle is idle, the connecting device can be stored in the storage space.

[0020] By adopting the above technical solution, when transporting goods, the connecting device can connect two adjacent transport vehicles to realize multi-vehicle linkage transportation and improve transportation efficiency; when idle, the connecting device can be stored in the storage space to avoid occupying extra space. Combined with the connecting rod and the sleeve block, the adjacent transport vehicles can be stacked to form a storage space to store the pulleys and the folded push frame, further saving storage space.

[0021] Optionally, the connecting device includes a mounting base disposed at one end of the base plate, a connecting frame rotatably disposed on the mounting base, and a connecting pin disposed at the other end of the base plate, wherein the end of the connecting frame away from the mounting base is provided with a connecting hole for the connecting pin to be inserted.

[0022] By adopting the above technical solution, when the transport vehicle is transporting goods, the connecting holes of the connecting frame can be inserted into the connecting pins of the adjacent transport vehicle to realize the connection between the two adjacent transport vehicles and improve the transport efficiency; when the transport vehicle is idle, the connecting device can be stored in the storage space between the floor plates of the two adjacent transport vehicles to reduce space occupation.

[0023] Optionally, rotating rods are provided on both sides of the connecting frame, and two mounting seats are provided, each mounting seat having a fourth hole, with the two rotating rods respectively inserted into and rotating within the fourth hole.

[0024] By adopting the above technical solution, the connecting frame can rotate on the mounting base by using the cooperation between the rotating rod and the fourth hole, which facilitates the connection of two adjacent transport vehicles when transporting goods, and the connecting device can be stored in the storage space when not in use.

[0025] Optionally, positioning rods are also provided on both sides of the mounting base. Each mounting base has a fifth hole on its upper surface along the vertical direction. The fourth hole extends into an oblong shape along the vertical direction. When the positioning rod abuts against the upper surface of the fourth hole, the positioning rod moves upward out of the fifth hole. When the positioning rod abuts against the lower surface of the fourth hole, the positioning rod engages in the fifth hole.

[0026] By adopting the above technical solution, the rotation of the connecting frame can be effectively limited by the engagement and disengagement of the positioning rod with the fifth hole, which facilitates the connection of two adjacent transport vehicles when transporting goods, and allows the connecting device to be stored in the storage space when not in use, further improving the convenience of stacking and storing transport vehicles.

[0030] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0031] This application discloses a stackable and connectable sheet metal parts transport vehicle. (Refer to...) Figure 1 The transport vehicle includes a base plate 1, several pulleys 2 set below the base plate 1, a hand-pushing frame 3 rotatably set on the base plate 1, and four connecting rods 4 set at the four corners of the base plate 1.

[0032] The base plate 1 is the fundamental load-bearing component of the entire transport vehicle. It is rectangular in shape and made of metal, such as steel, which offers good strength and durability. In other embodiments, high-strength engineering plastics can be used to reduce overall weight. The connecting rod 4 is a metal rod, its sidewalls fixed to the base plate 1 by welding or other methods, forming a stable connection. The upper end of the connecting rod 4 extends upwards beyond the upper surface of the base plate 1, and the lower end extends downwards beyond the lower surface of the base plate 1, where a sleeve block 5 is welded and fixed. The lower surface of the sleeve block 5 has a connecting groove for the connecting rod 4 to insert into. The pulley 2 is located below the base plate 1 and is generally a universal wheel with brakes, providing good steering flexibility and facilitating the operator to change the direction of the transport vehicle. The pulley 2 is fixedly connected to the mounting base 81 below the base plate 1 via bolts or other connecting parts. The mounting base 81 can be a metal block welded to the base plate 1 to ensure the stability of the pulley 2 installation.

[0033] Reference Figure 1 and Figure 2 When transport vehicles are limited, they can be stacked. When stacking, first rotate and fold the pusher 3 onto the base plate 1, and then connect the connecting rods 4 and the sleeve block 5 on the two adjacent transport vehicles. Specifically, the connecting rod 4 on the bottom transport vehicle can be inserted into the connecting groove of the sleeve block 5 on the upper transport vehicle, forming a storage space between the base plates 1 of the two transport vehicles. All the pulleys 2 and the rotated and folded pusher 3 can be stored in the storage space; thus, stable stacking and storage can be achieved, greatly reducing the space occupied by the limited transport vehicles.

[0034] Reference Figure 1 and Figure 3In this embodiment, the pusher 3 is respectively installed at both ends of the base plate 1. This allows operators to push the transport vehicle from either end of the base plate 1 according to the transportation environment and needs, improving operational convenience. Specifically, the pusher 3 includes two parallel first rods 31 and several second rods 32 connected between the two first rods 31. The first rods 31 and second rods 32 are typically made of metal tubing, such as stainless steel tubing, which has certain strength and corrosion resistance.

[0035] In an optional embodiment, the lower end of the first rod 31 can be directly rotatably connected to the base plate 1. For example, the lower end of the first rod 31 can be connected to the base plate 1 by a hinge. A hinge seat can be provided at the hinge, and a connecting component such as a pin can be used to enable the first rod 31 to rotate around the pin, thereby realizing the folding and unfolding of the push frame 3.

[0036] In this embodiment, the push frame 3 is directly rotatably connected to the connecting rod 4 without the need for an additional hinge seat. Specifically, the upper end of the connecting rod 4 has a mounting groove 41. The lower ends of the two first rods 31 located in the same push frame 3 are respectively inserted into the mounting grooves 41 of the two connecting rods 4 located at the same end of the base plate 1, and are rotatably connected to the connecting rod 4. At the same time, the mounting groove 41 extends towards the base plate 1 and to the side wall of the first rod 31, so that the first rod 31 can be rotated and folded towards the base plate 1. The connecting rod 4 is provided with a mounting member 6 for connecting the first rod 31, and a limiting member 7 that can restrict the rotation of the first rod 31 when the push frame 3 is in use.

[0037] Reference Figure 1 and Figure 3 In this embodiment, the mounting component 6 can be a mounting bolt 61 and a mounting nut 62. The connecting rod 4 has a first hole 42 for the mounting bolt 61 to pass through, and the first rod 31 has a second hole 311 for the mounting bolt 61 to pass through. After the mounting bolt 61 passes through the first hole 42 and the second hole 311, the mounting nut 62 is tightened to connect the first rod 31 to the connecting rod 4. It should be noted that when the first rod 31 is inserted into the mounting groove 41, there is a certain space between the side wall of the first rod 31 and the side wall of the mounting groove 41, allowing the first rod 31 to rotate smoothly. The mounting bolt 61 and mounting nut 62 facilitate the assembly and disassembly of the first rod 31. In other embodiments, the mounting component 6 can also be connected using a pin.

[0038] The limiting component 7 includes limiting rods 71 ​​disposed on both sides of the first rod 31 and a third hole 72 disposed on the upper surface of the connecting rod 4; the limiting rods 71 ​​are circular metal rods that can be welded and fixed. Both the first hole 42 and the third hole 72 extend vertically into an oblong shape, and the mounting bolt 61 can slide up and down in the first hole 42, and the limiting rod 71 can slide up and down in the third hole 72; when the mounting bolt 61 abuts against the upper surface of the first hole 42, the limiting rod 71 moves upward and disengages from the third hole 72, at which time the first rod 31 can rotate and fold freely; when the mounting bolt 61 abuts against the lower surface of the first hole 42, the limiting rod 71 is engaged in the third hole 72, restricting the rotation of the first rod 31, so that the pusher 3 is in a stable working state.

[0039] The implementation principle of this embodiment is as follows: When transporting sheet metal parts, the two pushers 3 are rotated to a vertical position, and the hands are released. The limiting rod 71 falls downward into the third hole 72, which restricts the rotation of the pushers 3. The operator pushes the pushers 3 and uses the pulleys 2 to move the transport vehicle. When the transport vehicle is idle, the pushers 3 are rotated and folded onto the base plate 1. Then, the connecting rod 4 of one transport vehicle is inserted into the connecting groove of the sleeve block 5 on the other transport vehicle, realizing the stacking of transport vehicles. This reduces the space occupied in the warehouse and improves the space utilization rate compared to traditional transport vehicles, thereby reducing the company's warehousing costs.

[0040] Example 2 Compared with Embodiment 1, the present application embodiment differs in that a connecting device 8 is added. If a large number of sheet metal parts need to be transported, the connecting device 8 can be used to connect adjacent transport vehicles to increase the transport capacity and save manpower.

[0041] Reference Figure 1 and Figure 4 In this embodiment, the connecting device 8 includes a mounting base 81 disposed at one end of the base plate 1, a connecting frame 82 rotatably disposed on the mounting base 81, and a connecting pin 83 welded and fixed to the other end of the base plate 1. The end of the connecting frame 82 away from the mounting base 81 has a connecting hole 821 for the connecting pin 83 to be inserted. In use, the mounting base 81 is rotated toward another transport vehicle, so that the connecting pin 83 of the adjacent transport vehicle is inserted into the connecting hole 821, thereby connecting two adjacent transport vehicles.

[0042] Reference Figure 4 and Figure 5Specifically, the overall structure of the mounting base 81 can be a triangular structure formed by bending a metal rod, with its base connected to the mounting base 81 and its apex bent to form a connecting hole 821; rotating rods 822 are welded and fixed on both sides of the bottom edge of the connecting frame 82; the mounting base 81 can be set as a whole as a metal plate structure, which is fixed vertically upward to the base plate 1 by welding, bolts, etc. The mounting base 81 is provided with two rotating rods 822 corresponding to the two mounting bases, and each mounting base 81 is provided with a fourth hole 811. The two rotating rods 822 are respectively inserted into and rotated in the fourth hole 811, so that the connecting frame 82 can rotate around the rotating rod 822.

[0043] The connecting frame 82 is also provided with positioning rods 823 on both sides. Each mounting base 81 has a fifth hole 812 on its upper surface along the vertical direction. The fourth hole 811 extends into an oblong shape along the vertical direction. When the positioning rod 823 abuts against the upper surface of the fourth hole 811, the positioning rod 823 moves upward out of the fifth hole 812, and the connecting frame 82 can rotate freely. When the positioning rod 823 abuts against the lower surface of the fourth hole 811, the positioning rod 823 is engaged in the fifth hole 812, so that the connecting frame 82 is fixed and it is convenient to connect adjacent transport vehicles.

[0044] The implementation principle of this embodiment is as follows: When the transport vehicle is used alone, the connecting frame 82 can be rotated to a vertical state. At this time, the positioning rod 823 is engaged in the fifth hole 812. With the help of the rotating rod 822, the connecting frame 82 is set on the floor in a vertical direction. This does not occupy the space of the base plate 1. At the same time, it can also assist the pusher 3 to limit the items placed on the base plate 1 and improve the stability during transportation.

[0045] When the transport vehicle is folded and stored, the connecting frame 82 rotates toward the base plate 1 and folds onto the base plate 1, so that it can be folded and stored together with the push frame 3 between the base plates 1 of the two transport vehicles.

[0046] When multiple transport vehicles are required, the connecting frame 82 rotates so that the connecting pins 83 of adjacent transport vehicles are inserted into the connecting holes 821, connecting two adjacent transport vehicles. This achieves the effect of connecting multiple vehicles during transportation to increase the transport capacity, and can be controlled by a single person, saving manpower.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
