Embodiment 1

[0065] The material carrying device, when driving and transporting on flat ground, controls the motor 34 to rotate forward through the touch control panel 5, the output shaft of the motor 34 drives the screw rod 34-1 to rotate forward through the coupling 35, and the drive and the screw rod 34-1 pass through The nut sleeve 36 connected by the spiral pair moves down along the limit guide rail 30-2, because the telescopic rod 37 is provided with multiple pieces, and one end of the telescopic rod 37 is fastened to the nut sleeve 36 by the fourth set of bolts 3-4 connection, the other end of the telescopic rod 37 is fastened to the telescopic disc 39 through the sixth set of bolts 3-6, the lower end cover 32 is provided with a plurality of through holes 32-1, and the telescopic rod 37 passes through the through holes 32-1 , the middle part of the second wheel frame 300 is provided with a connecting flange 301, the connecting flange 301 is fastened to the telescopic disc 39 through ...

Embodiment 2

[0067] A stair-climbing method for a material carrying device, when it is necessary to carry out stair-climbing transportation,

[0068] The first step: pull the device to the front of the first step through the handle 13;

[0069] Step 2: Control the reverse rotation of the motor 34 through the touch control panel 5, the output shaft of the motor 34 drives the screw rod 34-1 to reverse through the coupling 35, and drives the screw nut sleeve 36 connected with the screw rod 34-1 through the screw pair. As the limit guide rail 30-2 moves upwards, the telescopic rod 37 moves upwards along with the thread nut sleeve 36 and shrinks in the cylinder body 30. Move upward together with the universal wheel 302 until the bottom of the universal wheel 302 is coplanar with the first step, and then turn off the drive of the motor 34;

[0070] Step 3: Pull the device forward through the handle 13, so that the support wheel 21 moves to contact with the side wall surface of the second step, ...

Embodiment 3

[0075]On the basis of Embodiment 1 and Embodiment 2, a brake handle 13-1 is provided at the lower end of the handle 13, a brake disc 22 is provided for coaxial rotation on the wheel shaft 20, and a brake caliper is fixed on the side of the wheel frame 1. 23, and the brake caliper 23 is buckled on the brake disc 22, and the brake handle 13-1 is connected with the brake caliper 23 through a brake wire. This braking system ensures that the material is stopped in time when encountering obstacles or pedestrians. device to ensure the safety of transportation; the telescopic rod 37 is provided with multiple pieces, one end of the telescopic rod 37 is tightly connected with the nut sleeve 36 through the fourth group of bolts 3-4, and the other end of the telescopic rod 37 is connected through the sixth group of bolts 3 -6 is tightly connected with the expansion plate 39, the pressure plate 38 is tightly connected with the nut sleeve 36 through the fifth set of bolts 3-5, and the upper ...

Abstract

The invention discloses a material carrying device. The material carrying device comprises a bearing frame, a first wheel stand, a telescopic mechanism, two lithium batteries, a touch control screen and U-shaped lock catches, the bearing frame is provided with a first supporting rod, a second supporting rod and a third supporting rod, a handle is formed by integrally bending with the bearing frame, the first wheel stand is connected with the lower end of the bearing frame, a wheel axle is arranged at the lower end of the first wheel stand, supporting wheels are rotationally arranged at the twoends of the wheel axle, the upper end and the lower end of the telescopic mechanism are connected with the second supporting rod and the third supporting rod through the U-shaped lock catches in a fastened mode, the two lithium batteries are correspondingly arranged on the two sides of the telescopic mechanism, the lower ends of the lithium batteries are connected with the second supporting rod,the upper ends of the lithium batteries are connected with the third supporting rod, and the touch control screen is fixedly mounted on the third supporting rod and electrically connected with the lithium batteries. Traveling transport and stair climbing and obstacle crossing of different stairs are achieved, and in the processes of traveling and stair climbing, stable bearing of materials is maintained, and the phenomenon of tilting or bumping vibration is avoided.

Description

technical field [0001] The invention belongs to the technical field of transportation devices, in particular, the invention relates to a material carrying device and a stair climbing method thereof. Background technique [0002] Cargo transportation plays an important role in social life, and cargo transportation devices are indispensable devices in life. When transporting goods in the factory warehouse or carrying large and heavy objects up and down the stairs, the traditional method of manual handling is time-consuming, labor-intensive, labor-intensive, and poor in safety. [0003] At present, the devices that can simultaneously realize the functions of driving and climbing stairs and surmounting obstacles mainly include planetary wheel type, crawler type, leg-foot type, compound kinematic mechanism and variable structure type. Among them, planetary wheel type and crawler type are used more. [0004] 1. Features of the planetary wheel-type stair-climbing material carryin...
