Description

Throttle setting

Technical field

The utility model relates to a kind of mine ventilation facility, particularly relates to a kind of air door that is used for the distinguished and admirable usefulness of manufacture control under the coal mine.

Background technology

In order to ensure production safety, the safety regulations in coal mine regulation, must there be the ventilation system of independent and perfect in the colliery.Must build air door in the airway, down-hole for this reason, close ventilation equipments such as wall, air crossing.Air door is one of modal ventilation equipment in the downhole production of colliery, its effect mainly is regulate air quantity, be open to traffic, pedestrian etc.Under the coal mine in the ventilation system, air door be cut off under the mine, outgoing airflow, but again can the current a kind of facility of guarantor's car.According to the ventilation safety quality specifications, one group of air door needs to install the twice air door at least, and people's car by the time can not open simultaneously.Mainly contain in the prior art and utilize closed-loop path fluid power to promote latch, these equipment mostly need power sources such as extraneous wind or electricity, exist parts to cooperate defective tightness in various degree, poor stability, and the operation timeliness is short, the uncertain problem of unfailing performance.

Vehicles such as mine car, flat car, fork truck are the main tool of colliery downhole materials transportation.Since the twice air door of one group of air door people's car by the time can not open simultaneously, vehicle needs through stopping and a series of processes such as moving, arrange and connect, in these processes through air door the time, car need be stopped and hold, continue the next course of work again.At present, existing car arrester is by manually-operated, inconvenience, and work efficiency is low, and labour intensity is big, and the safety inadequately that operates.Temporarily hold up traffic mode but all have the not high defective of security reliability of down-hole, often because of factors such as peopleware and responsibility cause amplify sliding, even hurt sb.'s feelings, damage equipment etc.

The utility model content

The purpose of this utility model just is: a kind of throttle setting is provided, and it is a kind of easy to use, and the fluent movements that are open to traffic are smooth, prevents to squeeze people, safe and reliable, reusable, high-quality coal mine air door.

For solving the problems of the technologies described above, technical scheme provided by the utility model is:

Throttle setting comprises the twice air door, opens and closes between the twice air door and closes interlocking, and the pneumatic control system of control door leaf folding also comprises operation control valve and the anti-extrusion people's device that prevents unexpected folder people; Air door does not have threshold, and parallel orbit passes the twice air door, and the forward and backward side of per pass air door is car arrester, and the distance when closed is greater than air door folding radius apart from air door for car arrester, and operation control valve is connected with the folding control link of pneumatic control system and car arrester; Described anti-extrusion people's device is arranged on the doorframe; Described car arrester bottom is fixing in orbit.

Described anti-extrusion people's device comprises a connecting rod, pivoted arm and compression spring, and door connecting rod one end is butted on the door leaf, described pivoted arm one end rotational fixation, and the other end is provided with the bar shaped chute; Be fixed with the bearing pin of projection on the described door connecting rod, bearing pin snaps in the chute, and the bearing pin inboard is provided with the compression spring.

Described twice air door anti-extrusion people's distance at closing time is 0.4-0.6m.

According to the technical scheme that the utility model provides, it has following advantage with respect to prior art:

Also comprise operation control valve and the anti-extrusion people's device that prevents unexpected folder people; The forward and backward side of per pass air door is car arrester, and car arrester reaches control and holds up traffic and the purpose of the state that is open to traffic.By operation control valve control door leaf folding and the current state of car arrester, order is finished the action of stopping-opening the door-being open to traffic-closing the door-stopping-opening the door, avoid the mine car accident to knock air door, reach current smoothly purpose, time saving and energy saving precise control, can realize automatic control, alleviate labour intensity effectively; Adopt modular construction, be convenient to the repetition dismounting and use; Can carry out suitability for industrialized production, also create condition for mine standardization construction.

Overall construction design is reasonable, and is simple to operate, and the security reliability height is easy for installation, and easy maintenance is reusable and overhead cost are low.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and embodiments:

Fig. 1 is a three-dimensional reference diagram of the present utility model;

Fig. 2 is the vertical view of the utility model apoplexy header case;

Fig. 3 is the structural representation of anti-extrusion people's device in the utility model.

The figure number explanation:

1 air door, 11 door leafs, 2 car arresters

41 connecting rods of 3 operation control valves, 4 anti-extrusion people's devices

411 bearing pins, 42 pivoted arms, 421 chutes

43 compression spring A parallel orbits

The specific embodiment

Throttle setting as shown in Figure 1, comprises twice air door 1, opens and closes between the twice air door 1 and closes interlocking, and air door 1 bottom does not have threshold, and parallel orbit A passes twice air door 1, and the forward and backward side of per pass air door 1 is car arrester 2.Device comprises the pneumatic control system of controlling the folding of system door leaf, also comprises operation control valve 3 and the anti-extrusion people's device 4 that prevents unexpected folder people.Operation control valve 3 is connected with the folding control link of pneumatic control system and car arrester.As shown in Figure 2, anti-extrusion people's device 4 is arranged on the doorframe; Car arrester 2 bottoms are fixed on the track A.Anti-extrusion people's device 4 comprises a connecting rod 41, pivoted arm 42 and compression spring 43, and door connecting rod 41 1 ends are butted on the door leaf 11, pivoted arm 42 1 end rotational fixation, and the other end is provided with bar shaped chute 421; Be fixed with the bearing pin 411 of projection on the door connecting rod 41, bearing pin 411 snaps in the chute 421, and bearing pin 411 inboards are provided with compression spring 43.

In order to guarantee that door leaf 11 can open fully, car arrester 2 apart from air door the distance when closed greater than air door folding radius.Twice air door of the present utility model anti-extrusion people's distance at closing time is 0.4-0.6m.

As shown in Figure 2, be wind header case vertical view.Air door switch, interlocking, and car arrester interlock required drive are for mine is provided compressed air for oneself.Door connecting rod 41 is released in the arm bearing pin rotation but being switched on or switched off of operation control valve control cylinder, promotion pivoted arm 42 rotate, and door leaf 11 is unlocked.

When the master cylinder piston bar was withdrawn fully, door leaf was promptly closed tight.In case when between the two fan doors people or object being arranged, then door leaf should not closed tight, vertical welding is connected to the bearing pin 411 extruding compression springs 43 on the connecting rod 41, moves inward along the chute on the pivoted arm 42 421; As shown in Figure 3, after personnel or object were withdrawn, because the effect of compression spring 43, door leaf 11 can be closed tight.

Oppositely door leaf can be made according to user's needs.

Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or variation, therefore, all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
