Description

Technical Field

[0001] This utility model relates to the field of sheet metal conveying vehicle technology, and more specifically, to a sheet metal conveying vehicle. Background Technology

[0002] A sheet metal conveyor is a vehicle specifically designed for transporting flat objects such as sheet metal. It is widely used in industrial production, construction, and other fields. In operation, the sheet metal is placed on a support component, the centering component is adjusted to position the sheet metal in the center of the support component, and then the moving component drives the vehicle to move, transporting the sheet metal to the designated location.

[0003] Existing sheet metal conveyor vehicles still have some problems. During the conveying process, the sheets are stacked together, which is inconvenient and can easily damage the sheets, especially when using mechanical equipment to unload them directly, which can easily cause wear and tear. The same sheet metal conveyor vehicle cannot adapt to sheets of different sizes, so multiple sheet metal conveyor vehicles need to be configured, which increases the manufacturer's costs. Utility Model Content

[0004] The present invention aims to at least partially solve one of the aforementioned technical problems in the prior art. Therefore, one objective of the present invention is to provide a sheet metal transport vehicle capable of transporting sheets of different widths, reducing equipment investment costs, improving the flexibility of application scenarios, and facilitating the loading and unloading of sheets.

[0015] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0016] like Figures 1 to 3 As shown, a sheet metal conveying vehicle includes: Base frame 1, two base frames 1 are provided, and the two base frames 1 are arranged in parallel with a gap between them; Upright pole 2, two upright poles 2 are provided, and the two upright poles 2 are respectively fixedly placed on the upper end of the two base frames 1; each upright pole 2 is fixedly provided with multiple horizontally arranged support rods 3, the multiple support rods 3 are all above the base frame 1, and the multiple support rods 3 are arranged at equal intervals along the axial direction of the upright pole 2. Cross link 4, which is movably connected to each of the two uprights 2; Two electric push rods 5 are provided. The telescopic ends of the two electric push rods 5 are connected to one of the base frames 1, and the other end of the electric push rod 5 is connected to the other base frame 1.

[0017] In practical applications, when transporting boards of different widths, the two electric push rods 5 are activated. The extension or retraction of the electric push rods 5 causes the two connected base frames 1 to move in a parallel direction, thereby changing the distance between the two uprights 2. During this process, the cross connecting rods 4 move synchronously with the change in the spacing of the uprights 2, maintaining the relative position stability of the two uprights 2 through their own cross support structure, preventing the uprights from tilting. After the spacing is adjusted to suit the width of the board, the board is placed horizontally on the support rods 3 corresponding to the uprights 2 on both sides. Since the support rods 3 are arranged at equal intervals along the axial direction of the uprights 2, a multi-layer bearing space can be formed, realizing the layered placement of multiple boards. After placement, the entire equipment is moved to transport the board to the target location. The layered placement of multiple boards facilitates subsequent loading and unloading of the boards.

[0018] In this embodiment, the spacing between the two base frames 1 can be flexibly adjusted via the electric push rod 5, allowing for the transport of boards of different widths without changing equipment, reducing equipment investment costs and improving the flexibility of application scenarios. The multiple sets of support rods 3 on the uprights 2 form a multi-layer bearing surface, enabling the simultaneous transport of multiple boards, avoiding the inefficiency of transporting only one board at a time, and is especially suitable for scenarios such as factories and building materials markets that require bulk transfer of boards. The cross linkage 4 provides cross support for the uprights 2, effectively preventing the uprights 2 from tilting and the boards from slipping during transportation. At the same time, layered placement avoids the stacking and squeezing of boards, reducing surface scratches, deformation and other losses, and facilitating loading and unloading. Compared with traditional conveyor carts that manually adjust the spacing, the electric push rod 5 achieves automated adjustment, eliminating the need for manual effort to push or pry the base frames to adjust the spacing, reducing the labor intensity of operators, improving adjustment efficiency, and also greatly adjusting the volume of the board conveyor cart, reducing the space occupied by the board conveyor cart when idle.

[0019] The above embodiments also include: There are two telescopic rods 6, each positioned between the two base frames 1, and located on either side of the electric push rod 5; both ends of each telescopic rod 6 are connected to the two base frames 1 respectively.

[0020] In practical applications, the two ends of the telescopic rod 6 are fixed to the two base frames 1 respectively, and are symmetrically distributed on both sides of the electric push rod 5. When the electric push rod 5 extends and retracts, causing the two base frames 1 to move closer or further away, the telescopic rod 6 will extend or shorten synchronously, always maintaining a rigid connection with the two base frames 1. Since the telescopic rod 6 can only extend and retract along its own axis and cannot deviate in a direction perpendicular to the axis, it can restrict the two base frames 1 to move only in a parallel direction, avoiding left and right misalignment, twisting, etc. when adjusting the spacing of the base frames 1. In this embodiment, when adjustment is made solely by the electric push rod 5, the base frame 1 may tilt slightly due to uneven force. The telescopic rod 6 provides auxiliary support from both sides, balancing the driving force of the electric push rod 5 and ensuring that the two base frames 1 remain parallel. This prevents the uprights 2 and support rods 3 from becoming unstable due to base frame misalignment. The two telescopic rods 6 can share some of the weight of the material and the vibration and impact during transportation, preventing the electric push rod 5 from bearing lateral or longitudinal stress alone for a long time, extending the service life of the electric push rod 5, and reducing equipment maintenance costs. The synchronous extension and retraction of the telescopic rods 6 can provide guidance for the movement of the base frame 1, preventing the base frame 1 from getting stuck due to uneven ground or gaps between components during movement, making the spacing adjustment process smoother, especially suitable for precise adjustment when transporting heavy materials.

[0021] In the above embodiments, the cross link 4 includes: The first rod 401 has its lower end rotatably connected to a base frame 1, and its upper end is inclinedly connected to another upright 2. The second rod 402 has its lower end rotatably connected to another base frame 1, and its upper end is inclinedly connected to a vertical pole 2. The middle parts of the first rod 401 and the second rod 402 are rotatably connected.

[0022] In practical application, the first rod 401 and the second rod 402 are rotatably connected in the middle by components such as a pin. The lower ends of the first rod 401 and the second rod 402 form fixed rotation fulcrums with the two side base frames 1, respectively, and the upper ends of the first rod 401 and the second rod 402 are movably connected with the opposite uprights 2. When the electric push rod 5 drives the two base frames 1 to move closer or further away, the two uprights 2 move synchronously, causing the upper ends of the first rod 401 and the second rod 402 to slide along the uprights 2. Due to the hinge in the middle, the first rod 401 and the second rod... 402 will rotate synchronously around the hinge point, and the cross angle will be precisely adjusted according to the distance between the two base frames 1, always maintaining a symmetrical X-shaped support state; after the weight of the plate is transmitted to the upright 2 through the support rod 3, the force on the upright 2 will directly act on the upper movable point of the first rod 401 and the second rod 402. Since the first rod 401 and the second rod 402 are hinged in the middle, the force on one side of the upright 2 will be instantly transmitted to the other side of the upright 2 through the hinge point, and then distributed to the opposite base frame 1, forming a closed-loop force path, realizing real-time balance of the force on both sides.

[0023] In this embodiment, the central hinge ensures that the first rod 401 and the second rod 402 move synchronously, preventing unilateral jamming or support shifting due to friction differences or uneven force distribution at the moving ends. This ensures that the uprights 2 on both sides maintain a symmetrical posture when the base frame 1 is adjusted, preventing the plates from slipping due to the tilting of the uprights 2. Compared to crossbars without a central connection, the structure of the first rod 401 and the second rod 402 forms a more stable triangular force-bearing unit, significantly improving its resistance to deformation. Especially when multiple layers of heavy plates are placed, it can effectively resist the longitudinal bending and lateral tilting of the uprights 2, greatly increasing the maximum load capacity of the equipment. The central hinge... This makes the movement trajectory of the first rod 401 and the second rod 402 more precise and controllable, and the contact friction between the upper moving point and the upright 2 more uniform, avoiding the aggravation of local wear caused by excessive force on one side; at the same time, after the force is distributed through the hinge point, the stress of each connection part is more balanced, reducing the risk of loosening or breakage of the parts; the X-shaped hinge support of the cross link 4 and the parallel guide of the telescopic rods 6 on both sides complement each other: the telescopic rod 6 ensures that the base frame 1 does not shift, and the cross link 4 ensures that the upright 2 does not tilt. The two work together to ensure that the entire equipment remains rigid and stable during adjustment, load-bearing and movement, adapting to the needs of plate transportation under complex working conditions.

[0024] The above embodiments also include: The limiting component 7 is provided in two parts, and the two limiting components 7 are fixed to the upper ends of the two uprights 2 respectively. Each limiting component 7 is provided with a limiting groove 701 along the axial direction of the upright 2. Each limiting groove 701 is provided with a bolt 702 that can be limited to move along the limiting groove 701. One end of the bolt 702 is connected to the upper end of the first rod 401 or the second rod 402, and the other end of the bolt 702 passes through the limiting groove 701 and is threaded to the knob 703.

[0025] In practical applications, when the spacing of the base frame 1 is adjusted, the upper end of the cross link 4 moves with the upright 2, and the bolt 702 slides up and down along the limiting groove 701. The length of the limiting groove 701 directly limits the sliding stroke of the bolt 702, thereby constraining the maximum and minimum opening angles of the cross link 4, that is, the maximum and minimum spacing of the base frame 1. When the spacing of the base frame 1 is adjusted to the width of the matching plate, the knob 703 is tightened. The knob 703 fits tightly against the surface of the limiting part 7, and the position of the bolt 702 in the limiting groove 701 is locked by friction, so that the angle of the cross link 4 is fixed, thereby locking the relative position of the two uprights 2 and the base frame 1, preventing the spacing from shifting due to vibration during transportation.

[0026] In this embodiment, the length of the limiting groove 701 is preset to the maximum and minimum values ​​of the spacing between the base frame 1, preventing the electric push rod 5 from being overextended and causing damage to components such as the cross link 4 and the telescopic rod 6 due to exceeding the design stroke, such as bending of the link or disengagement of the telescopic rod, thus providing mechanical protection. After the knob 703 is tightened, the angle of the cross link 4 is fixed by the bolt 702, keeping the spacing between the upright 2 and the base frame 1 stable, avoiding unexpected changes in spacing due to road bumps and board shaking during transportation, and preventing the board from slipping off the support rod 3, which is especially suitable for moving in uneven terrain. For boards of different thicknesses and weights, the position of the bolt 702 in the limiting groove 701 can be adjusted and locked to select a more stable angle of the cross link 4, so that the equipment can flexibly balance between adaptability and stability.

[0027] In the above embodiment, each of the two uprights 2 is provided with a handle 8 at the end away from the support rod 3.

[0028] In practical applications, the handle 8 is fixed at the end of the upright 2 away from the support rod 3. This position avoids the area where the board is placed and will not interfere with the board being carried. The operator holds the two handles 8 with both hands and applies pushing or pulling force. The force is transmitted through the upright 2 to the base frame 1, which then drives the casters at the bottom of the base frame 1 to roll, thereby controlling the conveyor to move forward, backward or turn.

[0029] In this embodiment, the handle 8 can be designed with a non-slip structure, such as a rubber sleeve, to provide a comfortable and stable grip, reducing hand fatigue during pushing, and is especially suitable for long-distance transport of boards. By placing the handle 8 on the side away from the support rod 3, the operator's body does not need to be close to the load-bearing board when holding it, which can avoid accidental hand contact with the edge of the board and cause scratches, and at the same time prevent the board from accidentally slipping and hitting the hand during pushing, thus forming a safe operating distance. When transporting overweight or overwidth boards, two operators can hold the handles 8 on both sides respectively, apply force synchronously to control the direction and speed, and avoid the vehicle tilting due to uneven force when operating by a single person. This is more stable than pushing and pulling by a single person, and can improve the transport speed, making it suitable for collaborative handling scenarios of heavy boards.

[0030] The above embodiments include: Casters 9, four casters 9 are provided, two casters 9 are respectively placed on both sides of the lower end of one base frame 1, and the other two casters 9 are respectively placed on both sides of the lower end of another base frame 1.

[0031] In practical applications, the four casters 9 correspond to the lower sides of the two base frames 1, forming a four-point rectangular support structure, which evenly distributes the weight of the base frame 1 and all components above it onto the four casters. When the operator applies pushing or pulling force through the handle 8, the wheels of the casters 9 will roll along the ground, driving the entire conveyor to move in the direction of the applied force, thus switching from fixed load-bearing to mobile transportation. Since two casters 9 correspond to one base frame 1, when the electric push rod 5 adjusts the distance between the two base frames 1, the two sets of casters will move closer or further away from the base frame 1 in sync, always maintaining a fixed connection with the base frame 1, without affecting the support and rolling functions of the casters 9, ensuring that the conveyor can still move normally after the distance is adjusted.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
