Abstract
A mining linkage device for air door balancing comprises fixing racks on two sides, which correspond to air doors, wherein sprocket wheels are fixed on the fixing racks through torsion shafts fixed with the sprocket wheels and axially fixed with the air doors; a chain transmission closed ring is hung between the two sprocket wheels; the chain transmission closed ring comprises a chain, insert joints and regulating connection rods; the chain is hung on the sprocket wheels, the insert heads are connected with the tips of the chains, and the connecting rods are connected between the two insert heads on the same side of the chain sprockets; a hydraulic door closing device is mounted on a fixing rack; and an output rotating shaft of the hydraulic door closing device is peripherally fixed with the torsion shafts of the sprocket wheels. The mining linkage device used for balancing the pressure of the air doors can be started with a small force, and eliminates the dead points for rotation; the device not only ensures the smooth passage of personnel, but also avoids the generation of phenomena such as air leakage short circuit and ventilation short circuit in a tunnel and ensures the safety of a ventilation system. The mining linkage device has the advantages of simple structure, reliability, flexibility and convenience for regulation.
Description
Technical field:
The utility model relates to a kind of mining balance air door linkage, is used for two of balance air door and fans rotation synchronously between the door.
Background technology:
At present, the lifting of colliery automaticity, informationalized management makes underground work efficient improve, some pit shafts are deep, the big mine that waits of gas density, negative pressure is very big in the underworkings.The single pectinid door pressurized that is provided with in the indispensable tunnel is difficult to open, and accident potential's height; For this reason, need design and the alternative single pectinid door in the past of use balance air door.Existing balance air door utilizes four connecting rods to connect, the use weight cuts out, mechanism can not reliably move neatly, especially the weight of Zeng Jiaing has strengthened the unlatching dynamics, and air door is closed uncontrolled, very easily hurts sb.'s feelings and damages air door, serious damage may cause distinguished and admirable short circuit, violate mine safety ventilation rules, even cause serious accident such as gas explosion, directly influence mine safety production.
Summary of the invention:
The purpose of this utility model provides a kind of mining balance air door linkage, realizes that the pressure release of air door balance opens, and reaches light, opens the effect of balance air door safely and reliably.
The purpose of this utility model realizes as follows: the fixed mount of this is mining balance air door linkage comprises both sides, there is sprocket wheel to be arranged on fixed mount, articulates the chain drive closed-loop between two sprocket wheels by the axle of fixing with it and be used for circumferentially fixing of turning round with air door.
The chain drive closed-loop is by chain, fork-join head and regulate connecting rod and constitute, and chain is articulated on the sprocket wheel, and the fork-join head is connected on the termination of chain, is in to connect between two fork-join heads of sprocket wheel homonymy to regulate connecting rod.This chain drive closed-loop also can adopt the whole piece chain to constitute; Perhaps use wire rope instead, sprocket wheel adopts sheave, with a bit realizing with the fixing mode of sheave of wire rope.
Device hydraulic pressure door closer on the fixed mount, the output revolving shaft of hydraulic pressure door closer is circumferentially fixedlyed connected with the axle of turning round of sprocket wheel, makes the hydraulic pressure door closer as the power of closing air door.
When a pectinid door is artificially opened, pass an other pectinid door by this linkage and do reverse with it breakdown action, realize the purpose of interlock.After pedestrian or driving are passed through, utilize the hydraulic pressure door closer steadily to close air door effectively.
The utility model is realized the air door pressure balance, and opening force is little, does not rotate the dead point, and the personnel that both guaranteed pass through smoothly, has stopped again to leak out in the tunnel, the generation of phenomenon such as ventilation short circuit, guarantees ventilation system safety.Simple in structure, flexibly reliable, the convenient adjustment.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an A-A sectional view among Fig. 1.
The specific embodiment:
With reference to Fig. 1, Fig. 2, the both sides fixed mount 1 of corresponding air door 6 is arranged, sprocket wheel 3 is by fixing with it and being used for being arranged between 1, two sprocket wheel 3 of fixed mount and articulating the chain drive closed-loop with the circumferentially fixing axle 7 of turning round of air door 6.The chain drive closed-loop is made of chain 2, fork-join head 4 and adjusting connecting rod 5, chain 2 is articulated on the sprocket wheel 3, fork-join head 4 is connected on the termination of chain 2, be in to connect between two fork-join heads 4 of sprocket wheel 3 homonymies and regulate connecting rod 5 and constitute the sealing transmission rings, device hydraulic pressure door closer 8 on the fixed mount 1, the output revolving shaft of hydraulic pressure door closer 8 with turn round spools 7 and circumferentially fixedly connected.The utility model is carried out the opening ways that the Zola right side pushes away, and two pectinid doors 6 are realized interlock, and when a pectinid door 6 actives, another pectinid door 6 is done driven motion, oppositely opens with it.After the pedestrian passed through, hydraulic pressure door closer 8 acted directly on to turn round and rotates air door 6 on the axle 7, is effective and closes.
