Rotary type annular soil-bin test platform braking mechanism

Abstract

The invention discloses a rotary type annular soil-bin test platform braking mechanism which belongs to scientific research and test equipment. A braking mechanism rack is fixedly arranged at a part, which is located on the inner side of the periphery of an inner gear ring and cylinder combined body and is opposite to a center locating supporting wheel, on an annular rail rack; a braking driving cylinder and a friction plate seat are hinged to the braking mechanism rack; a driving shaft is inserted into the braking mechanism rack; a driving arm and a braking cam are fixedly arranged on the driving shaft; the driving arm is hinged to the braking driving cylinder; the braking cam is in contact matching with the friction plate seat; the two ends of a return tension spring are connected with the braking mechanism rack and the friction plate seat respectively; and a braking friction plate is fixedly arranged on the friction plate seat, and is in contact matching or disengagement contact matching with the inner wall surface of a cylinder of the inner gear ring and cylinder combined body. The rotary type annular soil-bin test platform braking mechanism can quickly and reliably brake a rotating annular soil-bin to allow the annular soil-bin to stop rotating, and has the advantages that the structure is novel and reasonable, unexpected accidents are avoided in a test, the test safety is ensured and the test efficiency is improved.

Description

technical field [0001] The invention belongs to scientific research and test equipment, and mainly relates to a braking mechanism of a rotating annular soil tank test bench for the test of agricultural machinery operating parts. Background technique [0002] Based on the characteristics of small footprint, compact equipment, high test efficiency, low manufacturing cost, and wide application range, the rotary annular soil tank test equipment has been widely used in the scientific research of agricultural machinery. The maturity of scientific and technological achievements has played a positive role in safeguarding. However, since the existing rotating annular soil tank test bench is not equipped with a braking mechanism to stop the rotation of the circular soil tank, it is found in the practice of scientific research and experiment that after the test bench works, it relies on slowly reducing the frequency conversion speed regulating motor. Frequency, by reducing the number ...

However, since the existing rotating annular soil tank test bench is not equipped with a braking mechanism to stop the rotation of the circular soil tank, it is found in the practice of scientific research and experiment that after the test bench works, it relies on slowly reducing the frequency conversion speed regulating motor. Frequency, by reducing the number of revolutions of the variable frequency speed regulating motor to drive the annular soil tank to decelerate until it stops rotating, the time of stopping is long and the use efficiency is low

Especially when the emergency stop of the test bench is required, the rotation of the annular soil tank cannot be braked, resulting in accidents
