Damping supporting leg for mounting mine ventilator

Abstract

The invention discloses a damping supporting leg for mounting a mine ventilator. The damping supporting leg for mounting the mine ventilator comprises a stand column, a rotating swivel nut and a supporting rod, wherein the rotating swivel nut is arranged at the top end of the stand column; a cavity of the rotating swivel nut is in threaded connection with the supporting rod; a nut is welded to the top end of the supporting rod; a backing ring is arranged at the bottom of the nut; a first damping spring is arranged at the bottom of the backing ring; a ventilator mounting frame is arranged at the bottom of the first damping spring; a second damping spring is arranged at the bottom of the ventilator mounting frame; and a damping adjusting piece is arranged at the bottom of the second damping spring. The first damping spring and the second damping spring sleeve the periphery of the supporting rod, so that the damping supporting leg for mounting the mine ventilator has good damping effect. Meanwhile, by the rotating swivel nut, a bearing, a limiting ring, a limiting hole and a latch as well as a spiral groove formed in the surface of a part, which is close to the bottom end, of the supporting rod, the damping supporting leg for mounting the mine ventilator has a height adjustable function.

Description

technical field [0001] The invention relates to the technical field of mining machinery, in particular to a shock-absorbing foot for installing a mine ventilator. Background technique [0002] Mines include coal mines, metal mines, non-metal mines, building materials mines and chemical mines, etc. Mine scale (also known as production capacity) is usually expressed by annual output or daily output. Annual output refers to the amount of ore produced by a mine every year. According to the size of output, it is divided into three types: large, medium and small. The size of the mine should be compatible with the economically reasonable service life of the mine. Only in this way can we save infrastructure costs and reduce costs. In the mine production process, the mining operation not only consumes the most manpower, material resources, occupies the most funds, but also is the production link with the greatest potential to reduce mining costs. The main way to reduce mining cos...

Problems solved by technology

[0004] The object of the present invention is to provide a shock-absorbing foot for installing a mine ventilator, which has the advantages of shock absorption and height adjustment, and solves the problem of high flatness of the ground when the mine ventilator is installed in the prior art and the problem that the ventilator is installed on the ground. The vibration generated during work affects the stability of the fan installation
