DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0024] like Figure 1-Figure 5 As shown, a material transport trolley with a stair climbing function of the present invention comprises a transport trolley body, the transport trolley body comprises a vehicle bottom plate 1 and two fixed columns 2 fixedly connected to one end of the vehicle bottom plate 1, the two fixed columns 2 are symmetrically arranged with the center of the vehicle bottom plate 1 as the center, a rotatable roller 3 is installed at the bottom of the fixed column 2, a rotatable baffle 6 is installed at the top of one end of the vehicle bottom plate 1 close to the fixed column 2, a battery 17, a fixed bracket 10, a drive motor 25, a gear commutator 8, a controller 22 and a support column 11 are fixedly connected to the bottom of the vehicle bottom plate 1, and the controller 22 is electrically connected to the battery 17 and the drive motor 25. The battery 17 is fixedly connected to the top of the fixed bracket 10, the drive motor 25 is fixedly connected to the bottom of the fixed bracket 10, the output end of the drive motor 25 is fixedly connected to the input end of the gear commutator 8, and the two output ends of the gear commutator 8 are fixedly connected to the climbing legs 9. Two support rods 14 are fixedly arranged at the bottom of the end of the vehicle floor 1 away from the fixed column 2. The two support rods 14 are symmetrically arranged with the center of the vehicle floor 1 as the center, and one end of the two support rods 14 is connected by a rotatable U-shaped handle 15. A control switch 16 is fixedly sleeved on the U-shaped handle 15, and the control switch 16 is electrically connected to the controller 22 through a wire.

[0025] The function of the storage battery 17 is to provide electric energy for the controller 22 , the drive motor 25 , and the electric hydraulic telescopic rod 18 .

[0026] The input end of the gear commutator 8 is driven to rotate by rotating the driving motor 25. It should be noted that the output end of the driving motor 25 is connected to the input end of the gear commutator 8 through a coupling. The two output ends of the gear commutator 8 respectively drive the two climbing legs 9 to rotate, thereby achieving the effect of the material transport trolley climbing up the stairs, so as to reduce the work intensity of the user in carrying materials and improve the work efficiency of the user in carrying materials.

[0027] The controller 22 is used to control the working state of the driving motor 25 and the electric hydraulic telescopic rod 18 .

[0028] Two fixing blocks 4 are fixedly connected to one end of the vehicle bottom plate 1 away from the U-shaped handle 15. The two fixing blocks 4 are symmetrically arranged with the center of the vehicle bottom plate 1 as the center. The two fixing blocks 4 are connected by a rotating member 5, and a baffle 6 is fixedly connected to the outer side wall of the rotating member 5. The baffle 6 can be rotated on the top of one end of the vehicle bottom plate 1, so that when the material transport trolley is used to transport materials, the baffle 6 can prevent the materials from sliding off. When the material transport trolley is not needed, the baffle 6 is rotated to be close to the vehicle bottom plate 1, saving floor space.

[0029] The two fixing blocks 4 are connected by a limiting plate 7, and the limiting plate 7 is used to limit the baffle 6. The function of the limiting plate 7 is to limit the baffle 6 to rotate only 90° on the vehicle bottom plate 1, which can prevent materials from sliding off the vehicle bottom plate 1 to a certain extent.

[0030] The gear commutator 8 is located between the two rollers 3 .

[0031] Four limiting cylinders 12 are fixedly connected to the bottom of the vehicle floor 1 for limiting the two support rods 14, wherein the two limiting cylinders 12 are connected to the support rods 14 by fixing bolts 13. The limiting cylinders 12 are slidably sleeved on the outer side wall of the support rods 14, so that the length of one end of the support rods 14 extending out of the vehicle floor 1 can be adjusted as needed, so as to facilitate pulling the material transport trolley forward on the ground.

[0032] One end of the support rod 14 is provided with a groove a, in which a rotating shaft is rotatably connected, and a fixed disc 23 is fixedly sleeved on the outer wall of the rotating shaft, and both ends of the U-shaped handle 15 are respectively fixedly connected to the outer wall of the fixed disc 23, and the fixed disc 23 is connected to the support rod 14 through a limiting bolt 24. The function of the fixed disc 23 and the limiting bolt 24 is to adjust the angle between the U-shaped handle 15 and the support rod 14 as needed, thereby improving the convenience of the material transport trolley when in use.

[0033] The climbing support leg 9 includes a climbing bracket 901 fixedly sleeved on the output end of the gear commutator 8. Both ends of the climbing bracket 901 are provided with grooves b, and detachable rubber tubes 902 are installed in the grooves b. During the rotation of the climbing support leg 9, the top of the stair step can be supported, and the roller 3 can be used to climb up. The function of the rubber tube 902 is to avoid damage to the surface of the stair step.

[0034] The bottom of the vehicle floor 1 is connected to a lifting plate 19 through an electric hydraulic telescopic rod 18, the electric hydraulic telescopic rod 18 is electrically connected to a controller 22, and the electric hydraulic telescopic rod 18 is located between the battery 17 and the controller 22. A universal wheel 20 is installed at the bottom of the lifting plate 19. The electric hydraulic telescopic rod 18, the lifting plate 19 and the universal wheel 20 are used to support the vehicle floor 1, so that when the vehicle floor 1 is in a horizontal state, the material transport trolley is pulled to transport materials. When the vehicle floor 1 is in an inclined state, the distance between the universal wheel 20 and the vehicle floor 1 can also be adjusted as needed to avoid affecting the use of the material transport trolley.

[0035] The lifting plate 19 is connected to the vehicle bottom plate 1 through a plurality of limiting telescopic rods 21, and the plurality of limiting telescopic rods 21 are arranged around the electric hydraulic telescopic rod 18. The limiting telescopic rod 21 is used to reduce the horizontal force received by the electric hydraulic telescopic rod 18 and prevent the electric hydraulic telescopic rod 18 from bending.

[0036] When the present invention is used, firstly, the distance between the U-shaped handle 15 and the vehicle floor 1 is adjusted as required, and fixed with the fixing bolt 13, then the angle between the support rod 14 and the U-shaped handle 15 is adjusted as required, and fixed with the limit bolt 24, then the baffle 6 is rotated so that the angle between it and the vehicle floor 1 is 90°, and finally the material is placed on the vehicle floor 1, and the material transport trolley is pulled to move. When it is necessary to transport materials upstairs, the material transport trolley is pulled to the stair steps, and the roller 3 is made to stick to the side of the stair steps, and then the control switch 16 is used to control the driving motor 25 to rotate, and the driving motor 25 rotates to drive the two output ends of the gear commutator 8 to rotate, and the two output ends of the gear commutator 8 rotate to drive the climbing legs 9 to rotate, so that the material transport trolley climbs on the stair steps, reducing the work intensity of the user in carrying materials and improving the work efficiency of the user in carrying materials. When only materials need to be transported on the ground, the control switch 16 is used to adjust the length of the electric hydraulic telescopic rod 18 so that the vehicle floor 1 is placed on the ground in a horizontal state, the materials are placed on the vehicle floor 1, and the material transport trolley is pulled to move.
