Abstract
The utility model discloses a pneumatic safety protection device. The device comprises a base, wherein a front light rail and a rear light rail are respectively and fixedly installed on the two sides of the base, and intermediate light rails are in lap joint between the front light rail and the rear light rail; a steel wire rope pressing plate is connected between the intermediate light rails on the two sides and hinged with the base; upward inclined lifting tracks are respectively arranged on the two sides of the base; two air cylinders are arranged on the other end of the base;, a lateral lifting shaft is fixedly connected with the front ends of the piston rods of the two air cylinders; running wheels are respectively installed on the two ends of the lifting shaft and matched with the lifting tracks; a connecting rod is connected between the lifting shaft and the base of the steel wire rope pressing plate; and pipes are fixed on the outer parts of the intermediate light rails. A broken rail and net dual-protection mode is adopted, and a mine car can also be effectively stopped from passing even if a steel wire rope is broken; and a double air cylinder and connecting rod control mode is adopted, so that the pneumatic safety protection device transfers more stably and responds faster.
Description
Technical field
The utility model relates to pneumatic safety device.
Background technology
At present, pneumatic safety device is a kind of appurtenance for the mine, pneumatic safety device is applicable to places such as inclined gallery, mine, can stop mine car invar silk fracture of rope to make mine car sweep away the descending point by actv., injures descending point personnel's safety and the normal operation of equipment.The protective device in-use performance instability of prior art, function of safety protection can not be guaranteed.
The utility model content
The purpose of this utility model provides a kind of pneumatic safety device, adopts the duplicate protection mode of disconnected rail and blanket net, even wire cable rupture also can stop mine car to pass through by actv..Pneumatic safety device adopts the mode of two cylinders and connecting rod, makes transmission more steady, and speed of response is faster.
The technical solution of the utility model is as follows:
Pneumatic safety device, include base, the base both sides are installed with preceding light rail respectively, back light rail, be overlapped with middle light rail between preceding light rail and the back light rail, be connected with the steel rope pressing plate between the middle light rail of both sides, the steel rope pressing plate is hinged on the base, the base both sides are respectively equipped with the lifting track that is tilted to, the other end of base is provided with two cylinders, the piston rod front end of two cylinders is fixedly connected with horizontal lift shaft, the two ends of lift shaft are separately installed with and promote the running wheel that track matches, and are connected with connecting rod between the base of lift shaft and steel rope pressing plate, and the middle light rail outside is fixed with pipe.
Described tube end is fixed with wear-resistant sleeve.
Described base is to be made of the channel-section steel welding.
The utility model adopts the duplicate protection mode of disconnected rail and blanket net, even wire cable rupture also can stop mine car to pass through by actv..Pneumatic safety device adopts the mode of two cylinders and connecting rod, makes transmission more steady, and speed of response is faster.
The pneumatic safety device of the utility model is easy for installation, can realize Long-distance Control, and actv. has solved difficult problems such as material superelevation, super wide linked network.During installation, pneumatic safety device is installed in the hole of staying in advance, three sleepers in shop, pneumatic safety device below, pneumatic safety device is installed in strict accordance with the regulation of specification sheets apart from the position of grade change point, with winning in succession track is linked up in pneumatic safety device, track must not be greater than 15mm in pneumatic safety device interface gap, rope gripper is installed on pneumatic safety device top, 4 ~ 5 meters, make a call to the anchor pole of 8 Φ 22-2000 according to the position of rope gripper preformed hole, the anchor pole top is fixed rope gripper with bolt.The link method of steel rope tail rope is according to shown in the diagram.Connect source of the gas, with threeway two cylinders are linked up, whether operation hand change over valve, perseveration are observed steel rope and track and are risen and fallen smooth and easy several times.
