Abstract
The utility model relates to a kind of coal mine ventilation door machinery Self-closing lock device.At present in common interlocking device for air doors design, most of colliery all adopts pulley principle, and utilize steel cable and assembly pulley to realize, need artificial operation against rules against regulations when transporting, maintenance capacity is large.A kind of coal mine ventilation door machinery Self-closing lock device, its composition comprises: air door wall (1), described air door wall has one group of fixed pulley A (4), lay winding wire ropes (2) on described fixed pulley, one end of described wire rope is connected with air door, the other end of described wire rope is connected with balance weight body (5) by fixed one group of fixed pulley B (3), described balance weight body is arranged in cylinder barrel (6), described cylinder barrel is U type cylinder barrel, there is in described cylinder barrel oil reservoir (7), there is between described balance weight body self-locking body (8).The utility model is applied to coal mine ventilation door machinery Self-closing lock device.
Description
technical field:
the utility model relates to a kind of coal mine ventilation door machinery Self-closing lock device.
background technology:
coal mine ventilation door machine automatization blocking device is applicable between underground coal mine pedestrian and driving air door, air door can be reduced largely to leak out, avoid opening because of air door causing Air escape branch phenomenon simultaneously, improve the effective wind rate of coal mine, guarantee the reliable, stable of coal mine ventilation system.Coal mine ventilation door causes the violation situation simultaneously opened to happen occasionally because pedestrian drives a vehicle, air door is opened simultaneously and has been upset normal ventilation system, cause Air escape branch, distinguished and admirable disorder, cause the calm or gentle breeze in place, local or methane accumulation, and then cause large coal mining accident.The main common air door of air door that traditional underground coal mine uses and self closing door, although self closing door ratio is easier to realize electric blocking, but on the one hand because its cost is higher, on the other hand because underground coal mine environment is poor, by steam, trickle, the factor impacts such as coal dust, performance is shorter for unreliable application life, so electric blocking is extensive not as mechanical latching Application comparison, at present in common interlocking device for air doors design, most of colliery all adopts pulley principle, steel cable and assembly pulley is utilized to realize, suspended counterweight under wire rope, the chain of air door is realized by controlling effective length, the a lot of problem of such existence, wire rope stretcher strain is influenced, artificial operation against rules against regulations is needed when transporting, maintenance capacity is large, there is different throttle locking devices simultaneously, when it uses, counterweight is comparatively fixing can not change its weight issue, balance weight body is placed in cylinder body simultaneously and can occurs directly to shoot down shock and cause application life low.
summary of the invention:
the purpose of this utility model is to provide a kind of coal mine ventilation door machinery Self-closing lock device.
above-mentioned object is realized by following technical scheme:
a kind of coal mine ventilation door machinery Self-closing lock device, its composition comprises: air door wall, described air door wall has one group of fixed pulley A, lay winding wire ropes on described fixed pulley, one end of described wire rope is connected with air door, and the other end of described wire rope is connected with balance weight body by fixed one group of fixed pulley B, described balance weight body is arranged in cylinder barrel, described cylinder barrel is U-shaped cylinder barrel, has oil reservoir in described cylinder barrel, has self-locking body between described balance weight body.
described coal mine ventilation door machinery Self-closing lock device, described self-locking body is circular sector, and described balance weight body has end cap, and described end cap and balance weight body are threaded connection, and described balance weight body is interior is have balancing weight in hollow, described balance weight body.
the beneficial effects of the utility model:
1. the utility model reliable in action, because fan-shaped locking member and balance weight body are rigid structures, two-way interaction's distortion is less, the flexible secondary effect that one group of fixed pulley B overcomes people's wire rope is provided with in centre, balance weight body is set to the structure that its inside hollow has breeding block, realizes the weight-adjustable joint of balance weight body, oil reservoir is set in cylinder barrel simultaneously, in balance weight body dropping process, realize its buffering, avoid direct shock.
the utility model structure is simple, easy to operate, practical, and manufacture maintenance easily, cost is low simultaneously.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.
accompanying drawing 2 is structural representations of the utility model balance weight body.
detailed description of the invention:
embodiment 1:
a kind of coal mine ventilation door machinery Self-closing lock device, its composition comprises: air door wall 1, described air door wall has one group of fixed pulley A4, lay winding wire ropes 2 on described fixed pulley, one end of described wire rope is connected with air door, and the other end of described wire rope is connected with balance weight body 5 by fixed one group of fixed pulley B3, described balance weight body is arranged in cylinder barrel 6, described cylinder barrel is U-shaped cylinder barrel, has oil reservoir 7 in described cylinder barrel, has self-locking body 8 between described balance weight body.
embodiment 2:
coal mine ventilation door machinery Self-closing lock device according to embodiment 1, described self-locking body is circular sector, described balance weight body has end cap 9, and described end cap and balance weight body are threaded connection, be, in hollow, described balance weight body, there is balancing weight 10 in described balance weight body.
