Description
Technical field
The utility model relates to a kind of tramroad transportation, is specifically related to a kind of slope vehicle rail transport double track list voussoir brake system, belongs to the mine safety technical field.
Background technology
The slope vehicle rail transport is the extensive a kind of transportation modes that adopt in mine such as colliery; Its types of transportation is to transport through the winch traction mine car group that is installed in the inclined shaft top; Owing to multiple reason, the disconnected rope of haulage cable often takes place easily, cause the safety misadventure of car crash.Several anti sport car system has been adopted in the mine at present, but all has such-and-such defective, does not have to form a kind of perfect solution.
Summary of the invention
The purpose of the utility model is for overcoming the weak point of above-mentioned prior art; A kind of slope vehicle rail transport double track list voussoir brake system is provided; Through between two joint mine cars, increasing the braking car that a joint has this brake system; Can under the situation of disconnected rope with mine car group braking Car Track on, through the braking car with the braking of mine car group on braking orbit, thereby avoid the generation of safety misadventure.
The utility model is realized through following technical scheme: a kind of slope vehicle rail transport double track list voussoir brake system; It is characterized in that: this brake system includes frame; Pull bar is arranged on the frame; There is retarding spring the pull bar lower end, and described pull bar has connecting rod through bolted connection, and the connecting rod two ends have pilot bar respectively; Described pilot bar has the pilot bar bearing respectively in two ends up and down, through regulating bolt spring, slider roller is arranged on the pilot bar bearing; Also have moving voussoir on the described pilot bar and decide voussoir, wherein there is the protruding wing below of moving voussoir.
Also have manual key on the described frame, braking has the key baffle plate on the key.
Described pilot bar is through the pilot bar seat supports, and the pilot bar bearing is fixed on the frame, has oblong aperture on the pilot bar bearing, and the pilot bar of square section can move along the direction that is parallel to wheel axis in this slotted hole under the effect of spring, slider roller.
Described connecting rod is articulated on the frame through bearing pin.
Described key baffle plate is fixed on the frame through adjustment nut.
Described pull bar front end is connected with the mine car round-link chain through bearing pin.
The beneficial effect of the utility model is: in case the winch generation rope-broken accident of traction mine car group takes place; Be installed in the braking car of two joints between the mine cars just under the effect of spring force; Drive moving wedge block movement; To move the voussoir wedge and decide between the fast and track of wedge, it is in orbit stuck to brake car, thereby realizes the braking of whole mine car group; When traction winch drew, under the effect of tractive force, moving voussoir withdrawed from from decide the wedge shape space between voussoir and the track, will brake car and track, thereby not hinder the traction of winch to the mine car group; In the process of gallery transportation, can brake system be closed through manual key, the braking car does not play brake action, and the mine car group can freely be transported.

The specific embodiment
As shown in the figure: a kind of slope vehicle rail transport double track list voussoir brake system; This brake system includes frame 2, and pull bar 1 is arranged on the frame, and there is retarding spring 17 the pull bar lower end; Described pull bar has connecting rod 8 through bolted connection, and the connecting rod two ends have pilot bar 16 respectively; Described pilot bar has pilot bar bearing 15 respectively in two ends up and down, through regulating bolt spring 13, slider roller 12 is arranged on the pilot bar bearing; Also have moving voussoir 11 on the described pilot bar and decide voussoir 10, wherein there is the protruding wing below of moving voussoir 11.
Also have manual key 4 on the described frame, braking has key baffle plate 5 on the key.
Described pilot bar 16 supports through pilot bar bearing 15; The pilot bar bearing is fixed on the frame 2; Have oblong aperture on the pilot bar bearing, the pilot bar of square section can move along the direction that is parallel to wheel axis in this slotted hole under the effect of spring 13, slider roller 12.
Described connecting rod 8 is articulated on the frame through bearing pin 7.
Described key baffle plate 5 is fixed on the frame through adjustment nut 6.
Described pull bar front end is connected with the mine car round-link chain through bearing pin 3.
Working process: when being used in the above mine car group of two joints, the braking car that is equipped with this brake system is connected between the mine car group first-half mine car, when having only one to save mine car, will brake car and be placed on before the mine car.Connection between the mine car group is that three pitch circle loop chains through the afterbody of prosthomere mine car connect with back mine car bearing pin.The disconnected rope of braking car braking procedure: will lose tractive force and relax when round-link chain that the disconnected rope of haulage cable connects braking car and prosthomere mine car takes place; Pull bar 1 is under the effect of retarding spring 17, and drivening rod 8 rotates around bearing pin 7, and connecting rod 8 drives pilot bar 16 motions; Because pilot bar 16 and moving voussoir 11 weld togethers; Thereby driven the motion of moving voussoir 11, brought moving voussoir into decide between voussoir 10 and the track wedge shape space, because the angle of voussoir is less than 2 times equivalent friction angle; Have self-locking property, thereby realized the braking of braking car.The upper section lower edge that moving voussoir has a protruding wing to block track, through with the combined action of braking car wheel, thereby limited the motion of braking car on this direction.Through the constraint on this both direction, under the situation that short rope takes place, will brake the car wedging in orbit, thereby realize the braking of mine car group.
The braking car stops the braking maneuver process: when traction winch draws; The prosthomere mine car drives pull bar 1 with respect to the motion of braking car through round-link chain; Pull bar 1 compression brake spring 17 and drivening rod 8 rotate around bearing pin 7, and connecting rod 8 drives pilot bars 16,11 motions of moving voussoir, thus will move voussoir take out of by track with decide the wedge shape space that voussoir is formed; And under the effect of spring 13 and slider roller 12; To move voussoir and push away track, thereby remove the constraint between braking car and the track, traction winch can drive the mine car group and freely go.
The braking car stops automated procedure in gallery: in gallery, manual key baffle plate 5 is blocked manual key 4 in this position, the course of action of braking car stops the braking maneuver process with the braking car, and the braking car does not produce braking.
