Abstract

The utility model relates to an air door self-locking device, in particular to a mechanical automatic locking device of coal mine air doors. The device solves the problem of an air flow short-circuit phenomenon caused due to the fact that the air doors are opened at the same time. According to the technical scheme, the mechanical automatic locking device of the coal mine air doors comprises a steel wire rope, a pair of fixed pulleys, a structure framework and a pair of solid counter weights, and is characterized in that a self-locking pin is further included, the fixed pulleys are arranged on the two sides of the upper portion of the structure framework, one end of the steel wire rope is connected with an air door connection rod, the other end of the steel wire rope penetrates through the fixed pulleys and is fixedly connected with the solid counter weights in a hung mode, and the self-locking pin is arranged in the middle of the structure framework and between the two solid counter weights. The mechanical automatic locking device has the advantages that by means of self weight of the counter weights, the steel wire rope is tensioned through the self-locking pin, another air door is prevented from being opened, the self-locking effect is achieved, and the locking device is simple in structure and low in manufacturing cost.

Description

Coal mine ventilation door machine automatization blocking device
Technical field
The utility model patent relates to a kind of air door self-locking device, relates in particular to a kind of coal mine ventilation door machine automatization blocking device.
Background technology
Coal mine ventilation door machine automatization blocking device is applicable under coal mine between pedestrian and driving air door, can reduce largely air door leaks out, avoid opening because of air door the Air escape branch phenomenon causing simultaneously, improve the effective wind rate of mine, guarantee the reliable, stable of mine ventilation system.Underground air door causes the violation situation of simultaneously opening 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 local place calm or gentle breeze or methane accumulation, and then cause large mine accident, for the safety in production of mine brings hidden danger.
Summary of the invention
The purpose of this utility model is to provide a kind of air door self-locking device, solves and opens the Air escape branch phenomenon causing because of air door simultaneously.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of coal mine ventilation door machine automatization blocking device, comprise wire rope, a pair of fixed pulley, structural framing, a pair of solid weight, it is characterized in that, also comprise self-lock pin, described fixed pulley is arranged on both sides, structural framing top, wire rope one end connects throttle linkage, and the other end connects solid weight through fixing suspension of fixed pulley, and described self-lock pin is located in the middle of the solid weight of frame mid portion two.
According to described coal mine ventilation door machine automatization blocking device, it is characterized in that, described self-lock pin is circular sector, described circular sector two straight flanges are provided with self-locking breach.
The utility model has the advantage of, utilize weight deadweight, by self-lock pin, wire rope is strained, prevent another door opening, arrive self-locking effect, this apparatus structure is simple, and cost is low.
Brief description of the drawings
Fig. 1 be the utility model patent overlook johning knot composition;
Fig. 2 is the self-locking device structure chart of the utility model patent;
Fig. 3 is machine automatization lock status figure under door opening state;
In accompanying drawing: 1, wire rope; 2, fixed pulley; 3, self-lock pin; 4, fixing hole; 5, structural framing; 6, solid weight; 7, throttle linkage; 8, air door.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The utility model as shown in the figure,
A kind of coal mine ventilation door machine automatization blocking device, comprise wire rope 1, a pair of fixed pulley 2, structural framing 5, a pair of solid weight 6, it is characterized in that, also comprise self-lock pin 3, described fixed pulley 2 is arranged on structural framing 5 both sides, top, and wire rope 1 one end connects throttle linkage 7, and the other end connects solid weight 6 through fixing suspension of fixed pulley 2, described self-lock pin 3 is located in the middle of the solid weight 6 of frame mid portion two, and described structural framing 5 is fixing by fixing hole 4.
According to described coal mine ventilation door machine automatization blocking device, it is characterized in that, described self-lock pin 3 is circular sector, described circular sector two straight flanges are provided with self-locking breach.
This device is realized and is had following functions feature: in the time of door opening, realize the automatic blocking to another road air door, twice air door can not be opened simultaneously, guaranteed the reliable, stable of mine ventilation system.
In the process of door opening, the rope traction that solid weight is subject to be connected with throttle linkage is raised to be sling, solid weight is got to self-lock pin above the solid weight being connected with another fan throttle linkage in the process of slinging, and is locked, and now another Yishanmen cannot be opened; In the time that air door is closed, solid weight free fall, self-lock pin is the solid weight Lock effect to another pectinid door no longer, and another Yishanmen can be opened.In the process of air door switch, air door machine automatization blocking device repeats above action, has realized the function of air door automatic blocking.
Embodiment recited above is described preferred embodiment of the present utility model; not design of the present utility model and protection domain are limited; do not departing under the prerequisite of the utility model design concept; various modification and improvement that in this area, common engineers and technicians make the technical solution of the utility model, all should fall into protection domain of the present utility model.
