Description

Technical Field

[0001] This utility model relates to the field of logistics turnover cart technology, and in particular to a logistics cart connection structure, a steel basket logistics cart, and an I-beam wheel logistics cart. Background Technology

[0002] In the production of products such as steel cord and steel strand, I-beams are used to wind the product wires. These I-beams rotate between different production workshops to transfer the product wires. During rotation, the I-beams can be wound with product wires, or they can rotate empty, with no product wires on them or the wires already released.

[0003] The turnover of the I-beam wheels is handled by logistics carts. If the I-beam wheels are carrying product materials, they need to be neatly arranged; if they are empty, they do not need to be neatly arranged, thus increasing the turnover rate. Conventional logistics carts are individual units, only able to move the I-beam wheels one cart at a time, but each cart requires manual pushing and pulling, consuming considerable manpower. By connecting the logistics carts in series, the I-beam wheels can be moved in a continuous line, providing convenience for workers.

[0004] The conventional method of connecting logistics carts is to use a pin-type connection. This means that a connecting plate with holes is set at the bottom of the front and rear of each logistics cart. After the connecting plates of two adjacent logistics carts are aligned, a pin is used to pass between the two connecting plates, thus connecting the two logistics carts. In this way, multiple logistics carts can be connected in series to form a row.

[0005] For example, patent publication number CN201249690Y discloses a vehicle bumper transport trolley, in which the connecting device consists of a U-shaped steel body with a central pin hole and pins of appropriate length, thereby allowing multiple trolleys to be connected sequentially. Another example is a textile fabric turnover device disclosed in patent publication number CN212579954U, in which traction plates with positioning holes are hinged at the front and rear of the turnover trolley, and pins are arranged between corresponding traction plates, inserting into the positioning holes to achieve connection between the turnover trolleys.

[0006] The above-described pin-type connection structure has the following problems: 1. The pin and the corresponding connecting plate are located at a low position on the trolley, requiring frequent bending and manual operation, resulting in high labor intensity. 2. The pin can only be inserted after aligning the holes on the corresponding connecting plates, which makes alignment difficult due to the lack of guidance, making pin insertion inconvenient. 3. There is contact friction between the two corresponding connecting plates, and the pin has to withstand a certain traction force, making the pin and connecting plate prone to wear. Summary of the Invention

[0007] To address the problems of inconvenient operation and easy wear of conventional pin-connection methods, this utility model provides a logistics vehicle connection structure, an iron basket logistics vehicle, and an I-beam wheel logistics vehicle. When two adjacent logistics vehicles are connected, they can achieve guided docking, which greatly facilitates manual docking operations. At the same time, the iron basket logistics vehicle can handle a large number of empty wheels, and the I-beam wheel logistics vehicle can handle I-beam wheels with product lines in an orderly manner.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A logistics vehicle connection structure is used to connect two adjacent logistics vehicles in front and behind, so as to facilitate the series connection of multiple logistics vehicles.

The insertion rod passes vertically upward through the guide sleeve and then bends horizontally to form a handle section. The handle section facilitates the operation of the entire insertion rod. The front end of the front connecting plate is recessed inward to form a docking groove. The connecting rod is mounted on the insertion rod. When the insertion rod rotates and moves, the connecting rod moves along with it. One end of the connecting rod is vertically inserted into the docking groove.

[0011] The rear connecting plate is located at the rear of the logistics vehicle. The rear end of the rear connecting plate protrudes outward to form a docking protrusion. The docking protrusion and the docking groove are adapted to each other, which facilitates the alignment and connection between logistics vehicles. The connecting rod passes vertically through the docking protrusion and is rotatably connected to the docking protrusion, which facilitates the connection between logistics vehicles.

[0012] Furthermore, the guide sleeve and the front connecting plate are fixedly connected to the front of the logistics vehicle. The guide sleeve is provided with a locking bolt, the head of which is pressed against the insertion rod to facilitate locking and unlocking of the insertion rod. The front connecting plate is provided with a front bearing, and the lower end of the insertion rod passes downward through the front bearing and connects to a limit block to avoid friction between the insertion rod and the front connecting plate, while also preventing the insertion rod from detaching upward. The mating groove and the front bearing are arranged in a front-to-back pattern.

[0013] Furthermore, the connecting rod is bent into a "𠃍" shape and is arranged on the insert rod above the front connecting plate. A reinforcing rib is provided between the connecting rod and the insert rod to improve the connection strength between the connecting rod and the insert rod. The horizontal end of the connecting rod is connected to the insert rod, and the vertical end of the connecting rod extends downward into the mating groove.

[0014] Furthermore, the front connecting plate and the rear connecting plate are arranged on the same horizontal plane to facilitate the interlocking and mating between the mating groove and the mating protrusion. The rear connecting plate is provided with a rear bearing, and the lower end of the connecting rod passes vertically through the rear bearing to avoid friction between the connecting rod and the rear connecting plate.

[0015] Furthermore, the mating groove has an inwardly concave arc-shaped structure, and the mating protrusion has an outwardly convex arc-shaped structure. The mating protrusion and the mating groove are interlocked to facilitate the mating of the front connecting plate and the rear connecting plate and ensure that the connecting rod passes accurately through the rear bearing.

[0016] A steel basket logistics vehicle includes the above-mentioned logistics vehicle connection structure, and also includes a chassis frame, a steel basket, a universal wheel and a directional wheel. The chassis frame is a "U"-shaped plate frame structure, which facilitates the carrying of the steel basket and the limiting of the steel basket. The front connecting component is set in the middle of the front of the chassis frame, and the rear connecting plate is set in the middle of the rear of the chassis frame, realizing the installation of the chassis frame and the logistics vehicle connection structure.

[0017] The iron basket is movably mounted on the chassis frame. The iron basket is not fixedly connected to the chassis frame. The iron basket has an open frame structure at the top, which makes it convenient to hold a large number of empty I-beam wheels. One universal wheel is provided on the front two sides of the chassis frame, and one directional wheel is provided on the rear two sides of the chassis frame, which facilitates the turnover and movement of the chassis frame.

[0018] A logistics vehicle with I-beam wheels includes the above-mentioned logistics vehicle connection structure, and also includes a double-layer frame, a platform plate, a positioning rod, two omnidirectional wheels and two directional wheels. The front connection assembly is provided at the front center of the double-layer frame, and the rear connection plate is provided at the rear center of the double-layer frame, thereby realizing the installation of the double-layer frame and the logistics vehicle connection structure.

[0019] The platform plate is installed above the double-layer frame, and multiple positioning rods are spaced apart on the platform plate.

Detailed Implementation

[0034] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0035] like Figures 1-4 As shown, a logistics vehicle connection structure is used to connect two adjacent logistics vehicles, allowing for convenient manual docking between them. The logistics vehicle connection structure includes a front connecting component 1 and a rear connecting plate 2, as shown... Figure 1 As shown.

[0036] The front connecting assembly 1 is located at the front of the logistics vehicle. The front connecting assembly 1 includes a front connecting plate 101, a guide sleeve 102, an insert rod 103, and a connecting rod 104. The guide sleeve 102 and the front connecting plate 101 are arranged vertically at intervals, and the guide sleeve 102 and the front connecting plate 101 are respectively fixedly connected to the front of the logistics vehicle.

[0037] A rod 103 is rotatably mounted on the front connecting plate 101. The rod 103 is a round rod with a certain height, such as... Figure 2 As shown. To facilitate the installation of the insertion rod 103, a front bearing 3 is provided on the front connecting plate 101, and the lower end of the insertion rod 103 passes downward through the front bearing 3. Under the action of the front bearing 3, the insertion rod 103 can not only rotate relative to the front connecting plate 101, but also move up and down, avoiding friction between the insertion rod 103 and the front connecting plate 101.

[0038] The insertion rod 103 passes vertically upward through the guide sleeve 102 and then bends horizontally to form a handle section 4. This allows the insertion rod 103 to move up and down between the guide sleeve 102 and the front connecting plate 101. The handle section 4 facilitates convenient circumferential and vertical movement of the insertion rod 103. To prevent the insertion rod 103 from accidentally detaching from the front connecting plate 101 during vertical movement, a limit block 5 is connected to the lower end of the insertion rod 103 after passing through the front bearing 3. The limit block 5 prevents the insertion rod 103 from excessively moving upward.

[0039] The front connecting plate 101 has an inwardly recessed front end forming a mating groove 6. The mating groove 6 has an inwardly concave arc-shaped structure, and the mating groove 6 and the front bearing 3 are arranged front and rear on the front connecting plate 101. A connecting rod 104 is provided on the insert rod 103. The connecting rod 104 is bent into an "X" shape and is arranged on the insert rod 103 above the front connecting plate 101. To improve the installation strength of the connecting rod 104, a reinforcing rib plate 7 is provided between the connecting rod 104 and the insert rod 103. The reinforcing rib plate 7 is a triangular plate.

[0040] Under normal conditions, one end of the connecting rod 104 is vertically inserted into the mating groove 6, that is, the horizontal end of the connecting rod 104 is connected to the insert rod 103, and the vertical end of the connecting rod 104 extends downward into the mating groove 6.

[0041] The rear connecting plate 2 is located at the rear of the logistics vehicle, and the front connecting plate 101 and the rear connecting plate 2 are arranged on the same horizontal plane, such as... Figure 3 As shown, the rear end of the rear connecting plate 2 protrudes outward to form a docking protrusion 8, which is an outwardly convex arc-shaped structure. The docking protrusion 8 and the docking groove 6 are adapted to each other. When two adjacent logistics vehicles are connected, the docking protrusion 8 and the docking groove 6 are inserted and matched. It is not that the docking protrusion 8 and the docking groove 6 are matched on only one logistics vehicle.

[0042] After the docking protrusion 8 and the docking groove 6 are inserted and engaged, the connecting rod 104 passes vertically through the docking protrusion 8 and is rotatably connected to the docking protrusion 8. Specifically, a rear bearing 9 is provided on the rear connecting plate 2, and the lower end of the connecting rod 104 passes vertically through the rear bearing 9, which avoids friction between the connecting rod 104 and the rear connecting plate 2, thereby enabling the connection of two adjacent logistics vehicles.

[0043] When connecting logistics vehicles using this utility model's connecting structure, two adjacent logistics vehicles are arranged one in front of the other. The insert rod 103 is operated to first rotate the connecting rod 104 out of the mating groove 6. Then, the two logistics vehicles are brought closer together, and the mating groove 6 and the mating protrusion 8 gradually engage, easily aligning the front connecting plate 101 and the rear connecting plate 2. Finally, the insert rod 103 is operated to insert the connecting rod 104 into the rear bearing 9 on the rear connecting plate 2, thus achieving the connection between the two logistics vehicles. Figure 4 As shown.

[0044] In order to optimize the product structure and lock the insertion rod 103, a locking bolt 10 is provided on the guide sleeve 102. The head of the locking bolt 10 is pressed tightly against the insertion rod 103 to fix the insertion rod 103 and prevent the connecting rod 104 from disengaging from the rear bearing 9. After loosening the locking bolt 10, the insertion rod 103 can continue to move.

[0045] An iron basket logistics vehicle, used for the large - batch transfer of empty wheels, includes the above - mentioned logistics vehicle connection structure, and also includes a chassis frame 11, an iron basket 12, a universal wheel 13, and a directional wheel 14, as Figure 5 and Figure 6 shown. The chassis frame 11 is a "return" - shaped plate - frame structure. Specifically, the chassis frame 11 is welded by four angle steels. An iron basket 12 is movably arranged on the chassis frame 11. The chassis frame 11 can carry the iron basket 12 and at the same time limit the position of the iron basket 12 to prevent the iron basket 12 from shifting. The iron basket 12 can be removed from the chassis frame 11. The iron basket 12 is a frame structure with an open upper end, and the iron basket 12 can be regarded as a wire - welded wire basket.

[0046] On both sides in front of the chassis frame 11, universal wheels 13 are arranged, and on both sides behind the chassis frame 11, directional wheels 14 are arranged to enable the movement of the chassis frame 11. When the logistics vehicle connection structure is installed on the iron basket logistics vehicle, a front connection component 1 is arranged in the middle in front of the chassis frame 11, and a rear connection plate 2 is arranged in the middle behind the chassis frame 11. Accordingly, two adjacent iron basket logistics vehicles can be conveniently connected, as Figure 7 shown.

[0047] After the iron basket logistics vehicle is installed with the logistics vehicle connection structure, multiple iron basket logistics vehicles can be conveniently connected. At the same time, an iron basket 12 is placed on the chassis frame 11, and a large number of empty wheels can be stored in the iron basket 12. The empty wheels do not need to be sorted, which can increase the turnover quantity of empty I - shaped wheels.

[0048] An I - shaped wheel logistics vehicle, used for the regular turnover of I - shaped wheels with product - line wires, includes the above - mentioned logistics vehicle connection structure, and also includes a double - layer vehicle frame 15, a platform plate 16, positioning rods 17, universal wheels 18, and directional wheels 19, as Figure 8 and Figure 9 shown. The double - layer vehicle frame 15 is a frame with a certain height welded by square tubes. On one side of the double - layer vehicle frame 15, a handrail 20 is arranged, and the handrail 20 extends upward to the height of the double - layer vehicle frame 15 to facilitate the operation and movement of the double - layer vehicle frame 15.

[0049] A platform plate 16 is arranged above the double - layer vehicle frame 15. The platform plate 16 is a rectangular plate to ensure that the upper part of the double - layer vehicle frame 15 is a whole plane. Multiple positioning rods 17 are arranged at intervals on the platform plate 16. The positioning rods 17 are arranged vertically, and the I - shaped wheels can be sleeved on the positioning rods 17 to position the I - shaped wheels, and the I - shaped wheels are supported by the platform plate 16.

[0050] The double-layer frame 15 is equipped with swivel wheels 18 on both sides of the front and directional wheels 19 on both sides of the rear, enabling the double-layer frame 15 to be movable. When the logistics vehicle connection structure is installed with the double-layer frame 15, a front connecting component 1 is installed at the center of the front of the double-layer frame 15, and a rear connecting plate 2 is installed at the center of the rear of the double-layer frame 15, thereby facilitating the connection of two adjacent I-beam wheel logistics vehicles.

[0051] After being equipped with a logistics vehicle connection structure, multiple I-beam wheel logistics vehicles can be easily connected together. When transporting I-beam wheels carrying product lines, the I-beam wheels can be fitted onto the positioning rod 17 and supported by the platform plate 16, allowing multiple I-beam wheels to be neatly arranged on the I-beam wheel logistics vehicle. Multiple I-beam wheel logistics vehicles connected in series can then be used to transport product lines.

[0052] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
