Problems solved by technology

[0002] The explosion-proof manhole covers currently used in our country have been blown away in several underground explosions. As a result, although the fans are intact, the ventilation cannot be restored as soon as possible.

Embodiment Construction

[0028] figure 1 As shown, the implementation consists of a spare explosion-proof manhole cover trolley 1, a trigger mechanism 2, a sliding device 4, a limit device 5 and a guide rail 3.

[0029] The guide rail 3 is arranged on the slope infrastructure, and the inclination angle of the slope infrastructure is 11 degrees;

[0030] The spare explosion-proof manhole cover trolley 1 is arranged on the guide rail 3, and one end of the spare explosion-proof manhole cover trolley 1 is supported by the support frame 14 of the triggering mechanism. The other end (pad frame) of trigger mechanism 2 is pre-buried on the ground. The sliding device 4 is arranged at one end of the guide rail 3 ; the limiting device 5 is fixedly connected with the sliding device 4 .

[0031] figure 2 As shown, the spare explosion-proof manhole cover trolley 1 includes a vehicle frame 6, a wheel assembly 7 and a spare explosion-proof manhole cover 8, the spare explosion-proof manhole cover 8 is fixedly conn...

Abstract

An automatic resetting device for a spare anti-explosion well lid of a mining air well belongs to mining machinery and is mainly used for ensuring that the spare anti-explosion well lid can be automatically reset quickly after explosive blast of an anti-explosion well lid is released. The device is characterized by comprising a spare anti-explosion well lid trolley, a triggering mechanism, a sliding device and a guide rail. The spare anti-explosion well lid trolley is arranged on the guide rail, the triggering mechanism is in contact connection with the spare anti-explosion well lid trolley, and the sliding device is arranged on the guide rail. By means of the automatic resetting device, ventilation can be quickly restored, and a secondary disaster is reduced.

Description

technical field [0001] The invention belongs to mining machinery and is mainly used to ensure that the spare explosion-proof manhole cover can be quickly and automatically reset after the explosion-proof manhole cover is blown away by the explosion shock wave, so as to quickly restore ventilation and reduce the occurrence of secondary disasters. Specifically relates to an automatic reset device for a spare explosion-proof manhole cover. Background technique [0002] The explosion-proof manhole covers currently used in our country have been blown away in several underground explosions. As a result, although the fan is intact, the ventilation cannot be restored as soon as possible, causing the underground ventilation to expand the accident and increase the number of casualties. [0003] Therefore, a method of using a spare explosion-proof manhole cover is proposed. It does not affect the basic functions of the existing explosion-proof manhole cover, but also ensur...
