Embodiment 1

[0029] combine figure 1 , figure 2 , image 3 , Figure 4 As shown, an adjustable step-distance stair climbing device includes a frame, two ladder wheels symmetrically installed at the bottom of the frame, a wheel drive mechanism that drives the wheels of the ladder to rotate, and multiple telescopic blocks that drive the telescopic blocks to expose or retract Telescopic block drive mechanism for ladder wheels. The two ladder wheels are symmetrically arranged on the left and right sides of the bottom of the frame, and the telescopic block can expose the circumferential surface of the ladder wheels, and can also be retracted into the inside of the ladder wheels. The interior of each ladder wheel is provided with a plurality of holes evenly distributed along the circumferential direction, that is, a plurality of holes are provided on the circumferential side of the ladder wheel, and the plurality of holes are evenly distributed along the circumferential side of the ladder wh...

Embodiment 2

[0039] Except the following technical features, all the other unmentioned technical features are the same as embodiment 1.

[0040] The difference between this embodiment and Embodiment 1 is that the structure of the telescopic block driving mechanism has been changed. combine Figure 5 , Figure 6 As shown, in this embodiment, the telescopic block driving mechanism includes a third motor, a second driving bevel gear installed on the output end of the third motor, and two groups of third driving assemblies separated on both sides of the second driving bevel gear. The two groups of third drive assemblies are arranged symmetrically and are located on the left and right sides of the second driving bevel gear. The third drive assembly includes a second driven bevel gear, a transmission shaft, a second thrust bearing sleeved on the transmission shaft, and a cam sleeved on the transmission shaft. The two second driven bevel gears mesh with the two sides of the second driving beve...

Embodiment 3

[0043] Except the following technical features, all the other unmentioned technical features are the same as embodiment 1.

[0044] The difference between this embodiment and Embodiment 1 is that the structures of the wheel drive mechanism and the telescopic block drive mechanism have been changed. combine Figure 6 , Figure 7 As shown, in this embodiment, there are two wheel drive mechanisms and telescopic block drive mechanisms, which are symmetrically arranged on both sides of the bottom of the vehicle frame. The wheel drive mechanism includes a fourth motor, a drive gear installed on the output end of the fourth motor, a drive axle, and a first thrust bearing. The first thrust bearing is installed on the vehicle frame, the first thrust bearing is sleeved on the driving axle, one end of the driving axle is connected on the ladder wheel, and the other end of the driving axle is meshed with the driving gear. The telescopic block drive mechanism includes a fifth motor, a c...

Abstract

The invention relates to an adjustable step pitch stair climbing device. The adjustable step pitch stair climbing device comprises a frame, two stair climbing wheels symmetrically installed at the bottom of the frame, a wheel driving mechanism used for driving the stair climbing wheels to rotate, a plurality of telescopic blocks and a telescopic block driving mechanism used for driving the telescopic blocks to expose out or retract into the stair climbing wheels. Each stair climbing wheel is internally provided with a plurality of hole grooves evenly distributed in the peripheral direction, the telescopic blocks are located in the hole grooves, a plurality of springs are arranged in the peripheral direction of the periphery surface of each telescopic block, one ends of the springs are connected to the stair climbing wheels, and the other ends of the springs are connected to the telescopic blocks. The wheel driving mechanism is installed on the lower portion of the frame, the output endof the wheel driving mechanism is connected to the stair climbing wheels, the output ends of the telescopic block driving mechanism is arranged in the stair climbing wheels and in contact with the telescopic blocks. The adjustable step pitch stair climbing device can be used for climbing stairs, and belongs to the technical field of stair climbing devices.

Description

technical field [0001] The invention relates to the technical field of stair climbing devices, in particular to a stair climbing device with adjustable step distance. Background technique [0002] With the rapid development of the economy, there are more and more high-rise buildings. In emergencies such as power outages, people have to climb stairs. In buildings without elevators, residents often climb stairs. When carrying heavy objects to climb stairs , it will be very laborious, and there is no better way to solve this problem at present. Contents of the invention [0003] Aiming at the technical problems existing in the prior art, the object of the present invention is to provide a stair climbing device with adjustable step distance, which can be used for stair climbing. [0004] In order to achieve the above object, the present invention adopts following technical scheme: [0005] A stair-climbing device with adjustable step distance, comprising a vehicle frame, two...
