Embodiment Construction

[0023] The invention provides a wheeled stair climbing wheelchair fatigue tester, comprising:

[0024] The bracket is a frame composed of bottom beams, middle beams, upper beams, and columns connecting the bottom beams, middle beams, and upper beams;

[0025] The rotating roller is rotatably supported on the left and right bottom beams;

[0026] Slide rails, installed vertically on the uprights, for guide wheel stair climbing wheelchairs;

[0027] The fixed frame is used to fix the wheeled stair climbing, the fixed frame is connected with the slide rail through the slider and is limited and guided by the slide rail;

[0028] A pair of reciprocal Hall sensors, installed on the left and right sides of the bracket, are used to count the number of up and down movements and the number of rotations of the wheeled stair climbing wheelchair;

[0029] A computer is used to process test data, and the output of the Hall sensor is connected to the computer;

[0030] The power supply pr...

Abstract

The invention discloses a wheel-type stair climbing wheelchair fatigue testing machine, which comprises a bracket, a rotating roller, a sliding rail, a fixed frame, one pair of mutually-emitted Hall sensors and a computer, wherein the rotating roller is supported on a left floor beam and a right floor beam; the sliding rail is vertically installed on the stand columns of the bracket; the fixed frame is used for fixing the wheel-type stair climbing wheelchair and is connected with the sliding rail by a sliding block; the mutually-emitted Hall sensors are installed on the left side and the right side of the bracket and are used for counting the vertical movement times and the operation number of turns of the wheel-type stair climbing wheelchair; the computer is used for processing test data; and the outputs of the Hall sensors are connected to the computer. According to the wheel-type stair climbing wheelchair fatigue testing machine disclosed by the invention, the complex degree of freedom of the movement locus when the wheel-type stair climbing wheelchair climbs the stair is simplified into the operation of a single degree of freedom, and the climbing wheel stressing situation of the wheel-type stair climbing wheelchair under the normal use status is simulated by the large-radius rotating roller. When the wheel-type stair climbing wheelchair travels on the wheel-type stair climbing wheelchair fatigue testing machine disclosed by the invention, all stair climbing actions can be simulated, and meanwhile, the tests are finished without moving. Meanwhile, test parameters, such as recorded revolving speed, number of turns, time, videos and curves, are provided by software.

Description

technical field [0001] The invention relates to a wheeled stair climbing wheelchair fatigue testing machine. Background technique [0002] Normal people cannot go up and down stairs without elevators and escalators in daily life. With the development of society and the increasing attention of vulnerable groups, the construction of some barrier-free facilities has gradually entered the family and us. Since the 2008 Olympic Games, all subway stations have been equipped with rail-type, crawler-type and wheel-type stair climbing devices, and various powerful manufacturers have begun to develop and produce related products and put them on the market. [0003] GB / T18029 is an authoritative testing standard for wheelchair performance issued by the General Administration of Quality Supervision, Inspection and Quarantine. It was officially promulgated in 2008. The standard provides detailed testing instructions for such products in terms of stability, static strength, electrical safe...
