DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Please refer to Figures 1 to 4 , Figure 1 A schematic structural diagram of a stacking and transporting device provided in a specific embodiment of the present invention; Figure 2 It is a structural schematic diagram of the stacking and transporting equipment when the supporting legs are in an extended state; Figure 3 It is a structural diagram of the stacking and transporting equipment in an operating state; Figure 4 This is a structural diagram of the lifting device of the stacking and transporting equipment.

[0025] A stacking and transporting device provided by an embodiment of the present invention includes a frame 1, on which a load-bearing platform 2 is provided. A front support leg 4 and a rear support leg 5 that extend and retract in the left-right direction are provided at the front and rear ends of the frame 1, respectively. A front lifting device 6 is provided on the movable end of the front support leg 4, and a rear lifting device 7 is provided on the movable end of the rear support leg 5. The drive systems 8 of the front support legs 4 and the rear support legs 5 are provided on the corresponding fixed ends. During specific operation, the front support legs 4 and the rear support legs 5 are extended, and then the material 10 is lifted by the front lifting devices 6 and the rear lifting devices 7 at both ends. The front support legs 4 and the rear support legs 5 are then retracted. After the material 10 moves to the top of the load-bearing platform 2, the material 10 is stably placed on the load-bearing platform 2, and finally the material 10 is transported to the target location. During transportation, the front support legs 4 and the rear support legs 5 can be retracted to adapt to a relatively narrow transportation environment.

[0026] Furthermore, the frame 1 is provided with a wheelbase adjustment device 3 for controlling the forward and backward movement of the front and rear support legs 4, 5. Specifically, the wheelbase adjustment device 3 comprises two telescopic support beams, with the front and rear support legs 4, 5 respectively connected to the load-bearing platform 2 via the two telescopic support beams. The power device for controlling the extension and retraction of the telescopic support beams is preferably located below the load-bearing platform 2. During operation, the wheelbase between the front and rear support legs 4, 5 can be adjusted according to the length of the material 10, thereby changing the spacing between the front and rear lifting devices 6, 7.

[0027] In order to facilitate the placement of the material 10 on the carrying platform 2, slide rails are provided above the fixed ends of the front supporting legs 4 and the rear supporting legs 5, and the telescopic ends are slidably connected to the slide rails. Therefore, after the telescopic ends of the front supporting legs 4 and the rear supporting legs 5 are retracted, the front lifting device 6 and the rear lifting device 7 can be located at the front and rear sides of the carrying platform 2 respectively, so that the material 10 lifted by the front lifting device 6 and the rear lifting device 7 can be dropped onto the carrying platform 2.

[0028] Specifically, the front lifting device 6 and the rear lifting device 7 respectively include a gantry and a lifting frame 12 and a lifting cylinder 11. The lifting frame 12 is used to lift the material 10. The lifting frame 12 is slidably connected to the gantry. The lifting cylinder 11 can drive the lifting frame 12 to rise and fall to realize the stacking operation of the material 10.

[0029] Among them, the gantry includes an outer gantry 13 and an inner gantry 14. The outer gantry 13 is fixedly connected to the movable end of the front support leg 4 or the rear support leg 5. The outer gantry 13 is connected to the inner gantry 14 in an up and down sliding manner. A sprocket is provided on the upper part of the inner gantry 14. The lifting frame 12 is connected to the outer gantry 13 through a chain passing around the sprocket. The fixed end of the lifting cylinder 11 is fixedly connected to the telescopic end of the support leg, and the telescopic end of the telescopic cylinder is connected to the inner gantry 14. Through the sprocket, the telescopic cylinder controls the lifting movement of the inner gantry 14, which will drive the lifting frame 12 to rise and fall at twice the speed, thereby improving the loading and unloading efficiency of the material 10.

[0030] In order to improve the adaptability of the lifting frame 12 to the size of the material 10, the lifting frame 12 is provided with two booms 15 with adjustable spacing, and the booms 15 are provided with slings 9. When the width of the material 10 is wider, the distance between the two booms 15 can be adjusted to be wider; when the width of the material 10 is narrower, the distance between the two booms 15 can be adjusted to be smaller.

[0031] Specifically, the lifting frame 12 is provided with a transverse guide rail 16, and the boom 15 is slidingly connected to the transverse guide rail 16. In addition, the lifting frame 12 is also provided with a telescopic device for controlling the left and right movement of the boom 15. The telescopic device can be a power device such as a cylinder or an oil cylinder. The transverse guide rail 16 can improve the stability of the movement of the boom 15.

[0032] Furthermore, steering wheels are provided on the fixed ends and movable ends of the front supporting legs 4 and the rear supporting legs 5, and servos are respectively installed at the bottom of the end of the fixed end and the end of the movable end, wherein the steering wheels can move in the horizontal plane to facilitate the left and right movement and the forward and backward movement of the frame 1.

[0033] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0034] The above is a detailed introduction to the stacking and transporting equipment provided by the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only intended to help understand the method and core concept of the present invention. It should be pointed out that, for those skilled in the art, without departing from the principles of the present invention, several improvements and modifications may be made to the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
