Embodiment Construction

[0019] The implementation mode of the present invention is illustrated by specific specific examples below, and those who are familiar with this technology can easily understand other advantages and effects of the present invention from the contents disclosed in this description. Obviously, the described embodiments are a part of the present invention. , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] Such as Figure 1-4 As shown, the special-shaped wheel of the stair climbing machine includes a chassis 1, a special-shaped blade 2 and a rubber wheel 3.

[0021] Chassis 1 is used as a motor or a transmission device after speed change, and can be cylindrical. An annular protrusion 12 is arranged inside the chassis 1, and a plurality of first threaded holes 13 are arranged at equal interv...

Abstract

The invention discloses a stair climbing machine special-shaped wheel. The stair climbing machine special-shaped wheel comprises a chassis, special-shaped blades and rubber wheels, and the three special-shaped blades are arranged on the surface of the outer ring of the chassis in a surrounding mode. The intervals of the three special-shaped blades are equal; the rubber wheels are arranged at theends, away from the chassis, of the special-shaped blades. Each rubber wheel is rotatably connected with the special-shaped blade through a first rotating shaft, one side of the special-shaped blade is in a cambered surface shape, the other side of the special-shaped blade is in a plane shape, a channel is formed in the position, close to the rubber wheel, of the cambered-surface-shaped side of the special-shaped blade, and a distance adapter is arranged at the position, located at the channel, in the special-shaped blade. By the design of the special-shaped blades, the deviation between the gravity center and a wheel working force point and a middle shaft is reduced; the requirement for power output is lowered, the situation that a motor is overloaded, operation is jammed or equipment isdamaged is avoided, safety is improved, the distance adapter can enable the special-shaped wheel to adapt to the situation that the horizontal length of a stair changes within a certain range, the application range is enlarged, the carrying cost is reduced through the overall design, and the carrying work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of stair climbing machines, in particular to a special-shaped wheel of the stair climbing machine. Background technique [0002] Stair climbers are often used in the field of logistics and handling, which can help people easily carry heavy objects up and down the stairs. The main efficiency of the stair climber depends on the wheels. Currently, the three-wheeled stair climber is widely used in the market. Its traditional structure There are also certain disadvantages. The wheel structure is relatively fixed and cannot be adjusted properly, resulting in unstable operation of the stair climbing machine. When carrying objects, the deviation between the center of gravity and the central axis and the working force point of the wheels is too large, which does not match the height and width of the stairs. If the working load of the motor fluctuates too much, if the manual traction is improper, it is easy to cause s...
