Abstract
The utility model relates to a safety device for an inclined shaft in mining production, specifically to an anti-sliding automatic safety door for the inclined shaft during elevation and transport. The anti-sliding automatic safety door comprises a door frame fixed at both sides of the inclined shaft and provided with a moveable transverse rod. The anti-sliding automatic safety door is characterized in that a door frame fixed pulley is fixed at the top of the door frame, and a pull cord is fixed on the moveable transverse rod. The pull cord is wound on the door frame fixed pulley and passes through a guide pulley fixed at the top of the shaft, and is then wound on a fixed pulley fixed on the ground of a vertical shaft and connected with the bottom end of a twin-core suspension wire pulley through a traction pull cord. The top end of the twin-core suspension wire pulley is fixed at the top of the vertical shaft through a steel wire rope and the middle part of the twin-core suspension wire pulley is threaded on a main elevating steel wire rope. One end of the main elevating steel wire rope is moveably suspended on a mine car, while the other end is wound on a winch drum. A shock-absorbing block is fixed at the upper end of the door frame. The automatic safety door designed by the utility model is simple in structure and easy to use local materials in the mine, and can be used together with a winch. The automatic safety door is reliable and agile to operate and high in safety and can prevent accidents.
Description
Technical field
The utility model relates to a kind of Safety Equipment of Shaft of digging up mine and producing, the anti-sport car automatic safety door of specifically a kind of inclined shaft hoisting transportation.
Background technology
Promote in the transportation at slope; Through regular meeting letter extension worker being taken place forgets hook and a chain of; With mine car mistake push inclined shaft or mine car be in operation pin takes place suddenly to jump, break off relations, disconnected rope phenomenon causes derailing accident; In order to prevent derailing accident to take place, its harm is reduced to bottom line, so inclined shaft must be installed catcher.
The slope mouth safety door is the important device that prevents inclined shaft hoisting transportation derailing accident, and present manually-operated safety door can not well be brought into play because of artificial factor in the use; More senior automation safety door is electronic, pneumatic, hydraulic pressure, mechanical linkage, electronic sensor, PLC control, though technology content is high with reliability, its input and installation, Maintenance and Repair are complicacy comparatively, is difficult for supporting promoting the use of with winch.Therefore inventing the anti-sport car safety door of a kind of new inclined shaft is highly profitable.
Summary of the invention
The purpose of the utility model is exactly the defective to existing anti-running device for incline, provides a kind of inclined shaft hoisting transportation anti-sport car automatic safety door, it can with the supporting use of winch, flexible operation is reliable, and is safe, prevents the generation of accident.
The purpose of the utility model is achieved in that it comprises the doorframe that is fixed on the inclined shaft both sides; Movable cross bar is housed on the doorframe, it is characterized in that: the top of doorframe is fixed with the doorframe fixed pulley, is fixed with stay cord on the movable cross bar; Stay cord passes the leading sheave that is fixed on the mine top on the doorframe fixed pulley; After being fixed on the ground-surface fixed pulley of straight well, be connected with the bottom of twin-core messenger wire pulley through the traction stay cord, the top of twin-core messenger wire pulley is fixed on the straight well top through steel rope, is through on the main hoisting cable in the middle of the twin-core messenger wire pulley again; One end activity of main hoisting cable hangs on the mine car, and the other end is on capstan drum.The upper end of described doorframe is fixed with damping block.
The utility model design-calculated automatic safety door simple structure is gathered materials on the spot easily in the mine, through practical application, installs, uses fast, need not be automatically controlled, and flexible operation is reliable, has very high safety benefit, promotes the popularization use easily.
Description of drawings
Fig. 1 is the structural representation of the utility model
The specific embodiment
Below in conjunction with accompanying drawing the technical scheme of the utility model is done and to be further described:
As shown in Figure 1, the utility model comprises the doorframe 13 that is fixed on the inclined shaft both sides, and movable cross bar 14 is housed on the doorframe 13; The top of doorframe 13 is fixed with doorframe fixed pulley 11 and 12; Be fixed with stay cord 10 on the movable cross bar 14, stay cord 10 passes the leading sheave 6 that is fixed on the mine top on doorframe fixed pulley 11 and 12, is connected with the bottom of twin-core messenger wire pulley 3 through traction stay cord 2 around being fixed on the ground-surface fixed pulley of straight well 4 backs again; The top of twin-core messenger wire pulley 3 is fixed on straight well 7 tops through steel rope 5; Be through on the main hoisting cable 1 in the middle of the twin-core messenger wire pulley 3, an end activity of main hoisting cable 1 hangs on the mine car 9, and the other end is on capstan drum 8.The upper end of described doorframe 13 is fixed with damping block 15.
The utility model principle of work: twin-core messenger wire pulley 3 upper ends connect and hang on the sky plate (hang length fall with twin-core messenger wire pulley just contact fixed pulley and be advisable) with the steel rope of Φ 8～10mm; When the mine car hook is transferred; Behind the slope mouth grade change point; The main hoisting cable 1 that drops on ground between capstan drum and the loose wheel can become the stretching state of tightening immediately; This moment, the twin-core messenger wire pulley 3 that is through on the main hoisting cable can increase, the traction that can and then make progress simultaneously of the safety door haulage cable 2 of Φ a 8～10mm of twin-core messenger wire pulley 3 lower end bonded assemblys, and this haulage cable is through being installed in underground fixed pulley 4; Being utilized in the little leading sheave leading sheave 6 of the buckle that plays corner, directional tagging on nation's wall, the top board is connected with movable cross bar 14 on the safety door; Movable cross bar 14 is elevated to the correct position of adjusting in advance by 2 tractions of safety door haulage cable thereupon, and safety door is promptly opened automatically, lets Safety for mine car pass through; If opposite letter is hung the worker because of work mistake; Mine car does not hang up hook and has just just arrived the disconnected suddenly rope of well head grade change point, jumps pin, broken off relations to inclined shaft go-cart or mine car, and main hoisting cable 1 will lose traction and be in relaxed state immediately and land, and twin-core messenger wire pulley 3 lands thereupon; Safety door haulage cable 2 is lax to the inclined shaft direction rapidly; Movable cross bar 14 on the inclined shaft safety door will utilize deadweight to fall rapidly, the SELF CL safety door, thus realization is held up traffic or the purpose of anti-derailing accident.
