Description

Air door counterweight device Technical Field The utility model relates to the technical field of air door counter weights, in particular to an air door counter weight device. Background The mine ventilation system is an important component of mine production and is a safety guarantee of mine production. The management of the air door is an important factor for reasonably perfecting a mine ventilation system, and the automatic air door cannot realize automatic closing of the air door after the air supply of the air door is stopped by the compressed air, so that the air door is closed after the air door stops the air supply by the air door counterweight; In the prior art, the damper counterweight is generally hoisted by a rope in the using process, so that the counterweight can directly strike the ground once the rope is broken, and a large potential safety hazard exists. Disclosure of utility model Therefore, the utility model aims to provide the air door counterweight device, which is used for protecting the counterweight block through the mutual matching of the air door counterweight component and the anti-falling locking component, and directly locking the counterweight block in a linkage way when the counterweight block falls out of a stroke, so that the problem of potential safety hazards caused by collision and rolling is avoided, and the use stability of the counterweight block is ensured. In order to solve the technical problems, according to one aspect of the utility model, the utility model provides a damper counterweight device, comprising: The air door counterweight assembly comprises a counterweight block, a connecting rope, a first vertical bracket and a second vertical bracket, wherein the counterweight block is arranged, the connecting rope is connected with the counterweight block, and the first vertical bracket and the second vertical bracket are arranged below the counterweight block; The anti-falling locking assembly comprises a second sliding block sleeved with the first vertical support, a round hole formed in the second sliding block, a supporting plate connected with the second sliding block, a disc fixed to the top surface of the supporting plate, an L-shaped bracket connected with the disc, a guide rod fixed to the inner bottom surface of the first vertical support, a top plate fixed to the top surface of the guide rod, a first sliding block sleeved with the first vertical support, a through hole formed in the first sliding block, a spring sleeved with the guide rod, a long slat connected with the first sliding block, a notch groove formed in the side wall of the long slat, a round shaft arranged in the notch groove, a sleeve sleeved with the round shaft, an L-shaped hook connected with the sleeve and a pressing plate. As a preferable mode of the damper weight device of the utility model, wherein the diameter of the top plate is larger than the inner diameter of the through hole, and the inner diameter of the circular hole is larger than the inner diameter of the through hole. As an optimal scheme of the damper counterweight device, a plurality of notch grooves are formed, and the position of each notch groove is provided with a corresponding round shaft, a sleeve, an L-shaped hook and a pressing plate. As a preferable mode of the damper counterweight device of the utility model, the second slider slides along the guide rod, and the circular hole penetrates the top plate. As a preferable scheme of the damper counterweight device, the second vertical support is identical to the first vertical support in structure, and the second vertical support is provided with an anti-falling locking assembly with the same structure. As a preferable scheme of the damper counterweight device, the damper counterweight device further comprises a joint assembly, wherein the joint assembly comprises a first threaded hole formed in the bottom surface of the counterweight and a second threaded hole formed in the outer wall of the counterweight.
