Description

Technical Field

[0001] The present application relates to the technical field of material transport devices, and in particular to a material transport vehicle for climbing stairs. Background Art

[0002] Material handling currently refers to the process of transferring raw materials, semi-finished products, or finished products from one location to another using various mechanical devices during production and processing. This process is crucial for achieving continuous, automated production lines, helping to improve production efficiency, reduce labor costs, and maintain consistency and controllability in the production process.

[0003] In the prior art, materials are usually transported using a transport trolley, where the materials are placed on the transport trolley and workers manually push the trolley to transport the materials.

[0004] The above-mentioned existing technical solutions have the following defects: for step areas, the existing material carts cannot transport the materials and can only be carried manually, which puts too much labor intensity on the workers. Utility Model Content

[0005] In order to reduce the labor intensity of workers when carrying materials on steps, the present application provides a material transport vehicle for climbing steps.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] The lifting of the lifting gear is 210。 English: A material conveying vehicle for climbing stairs includes a frame, which is rectangular as a whole, and the two corners at its front end are fixedly connected to a supporting leg, and each supporting leg is provided with a roller that can slide along the ground; the two corners at its rear end are respectively provided with climbing components; each climbing component includes a fixed rod and a movable rod, one end of the fixed rod is fixedly connected to the frame, and the other end of the fixed rod is hinged to the movable rod; each movable rod is provided with a roller that can slide along the ground at an end away from the hinged end of the fixed rod; the length of the supporting leg is less than the maximum length of the climbing component; the climbing component is also provided with an elastic member that can make the climbing component as a whole in a vertical state under its own elastic action; at least one climbing component connected to the frame is also provided between the supporting leg and the climbing component. When the ground is flat, several climbing components can drive the frame to move on the flat ground.

[0008] By adopting the above solution, because the length of the supporting legs is smaller than that of the climbing components, the supporting legs can climb the steps first; and because the movable rods can be bent along the supporting legs, when the movable rods abut against the side walls of the steps, the frame body continues to be pushed forward, the movable rods and the fixed rods are bent, and gradually climb up the steps, so that the entire frame body can climb onto the steps; when materials are handled in the step area, the labor intensity of workers is reduced.

[0009] Furthermore, the hinge point between the fixed rod and the movable rod is located on the side wall of the fixed rod away from the supporting leg, so that the movable rod can only bend in the direction away from the supporting leg.

[0010] By adopting the above solution, the arrangement enables the movable rod to bend only in a direction away from the supporting leg.

[0011] Furthermore, each of the movable rods is fixedly connected to a side wall away from the supporting leg with a limiting rod, the other end of the limiting rod is used to abut against the bottom wall of the frame, and the limiting rod is used to control the maximum bending angle of the movable rod and the fixed rod.

[0012] By adopting the above solution, the setting of the limit rod can control the maximum bending angle of the movable rod and the fixed rod, so that the total length of the movable rod and the fixed rod after relative bending is consistent with the supporting leg, so that the frame is in a balanced state.

[0013] Furthermore, a connecting piece is provided between the roller and the movable rod. The connecting piece is U-shaped as a whole with the U-shaped opening facing the ground. The top wall of the connecting piece is fixedly connected to the movable rod; the two ends of the roller shaft of the roller are respectively fixedly connected to the two sides of the inner wall of the connecting piece.

[0014] By adopting the above solution, since the connecting piece is provided, when the movable rod and the fixed rod are bent relative to each other, the roller can still abut against the ground, so as to facilitate the movement of the frame.

[0015] Furthermore, a handrail is fixedly connected to the rear end of the upper surface of the frame.

[0016] By adopting the above solution, the provision of the handrail frame facilitates the movement of the frame body and is also used to block materials placed on the frame body.

[0017] Furthermore, a blocking rod is fixedly connected to the front end of the upper surface of the frame corresponding to each supporting leg.

[0018] By adopting the above solution, the setting of the blocking rod makes it easy to block the materials placed on the frame to prevent them from falling.

[0019] Furthermore, a reinforcement rod is fixedly connected to the middle of the frame, and both ends of the reinforcement rod are fixedly connected to the two sides of the frame respectively, and the reinforcement rod is used to increase the bearing capacity of the frame.

[0020] By adopting the above solution, the provision of the fixing rod increases the bearing capacity of the frame.

[0021] Furthermore, one end of each of the limiting rods away from the movable rod is fixedly connected to a buffer pad.

[0022] By adopting the above solution, the provision of the buffer pad can reduce the sound generated by the collision between the limiting rod and the bottom wall of the frame, and can also prevent the limiting rod from scratching the bottom wall of the frame.

[0023] In summary, this application has the following technical effects:

[0024] 1. By setting up this transport vehicle, the supporting legs can climb the steps first; and when the movable rod abuts against the side wall of the step, the frame body continues to be pushed forward, the movable rod and the fixed rod bend, and gradually climb up the step, so that the entire frame body can climb onto the step; when carrying out material handling in the step area, the labor intensity of workers is reduced;

[0025] 2. By providing a connecting piece, when the movable rod and the fixed rod are bent relative to each other, the roller can still contact the ground, making it easier to push the frame to move;

[0026] 3. By providing a buffer, the sound generated by the collision between the limit rod and the bottom wall of the frame can be reduced, and the limit rod can be prevented from scratching the bottom wall of the frame. BRIEF DESCRIPTION OF THE DRAWINGS

The setting of the blocking rod 12 is convenient for blocking the materials placed on the frame 1 to prevent them from falling; a reinforcement rod 13 is fixedly connected to the middle part of the frame 1, and the two ends of the reinforcement rod 13 are respectively fixedly connected to the two sides of the frame 1, and the reinforcement rod 13 is used to increase the bearing capacity of the frame 1.

[0033] Reference Figure 1-Figure 2 In this embodiment, in order to enhance the stability of the conveying vehicle in conveying materials, two climbing components 3 are further provided between the climbing component 3 and the supporting leg 2. The two climbing components 3 are respectively provided on both sides of the bottom wall of the frame 1, that is, four climbing components 3 are provided in this embodiment; specifically, each side of the bottom wall of the frame 1 includes a supporting leg 2 and two climbing components 3.
