Description
Technical field
The utility model relates to a kind of tramroad transportation, is specifically related to a kind of slope vehicle rail transport single track folding wedge piece 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 single track folding wedge piece brake system is provided; Increase the braking car that a joint has this brake system between the mine cars through saving, can directly will brake car for the single-unit mine car and be placed on the mine car front under the situation of disconnected rope the mine car group being braked on the Car Track two; Through the braking car with mine car group braking 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 single track folding wedge piece 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, brakes key on the described frame in addition, and the key baffle plate is arranged on the manual key; Described pull bar has the framed structure that is made up of connecting rod and bar through bolted connection; In the described framework pilot bar is arranged, pilot bar has the pilot bar bearing up and down respectively, is fixed with spring, slider roller through setting nut 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.
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 bar and connecting rod are 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; The wedging of motion block wedge is being decided between the fast and track of wedge, and it is stuck on braking orbit 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 deciding wedge soon and the wedge shape space between the track, will brake car and separate with braking orbit, 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.

Among the figure: 1, pull bar, 2, frame, 3, bearing pin, 4, the braking key, 5, the key baffle plate; 6, retarding spring, 7, adjustment nut, 8, bar, 9, bearing pin, 10, connecting rod; 11, pilot bar bearing, 12, setting nut, 13, spring, 14, slider roller; 15, moving voussoir, 16, decide voussoir, 17, pilot bar, 18, wheel.
The specific embodiment
As shown in the figure: a kind of slope vehicle rail transport single track folding wedge piece brake system; It is characterized in that: this brake system includes frame 2, and pull bar 1 is arranged on the frame, and there is retarding spring 6 the pull bar lower end; Also have manual key 4 on the described frame, braking has key baffle plate 5 on the key; Described pull bar has the framed structure that is made up of connecting rod 10 and bar 8 through bolted connection; Pilot bar 17 is arranged in the described framework, and pilot bar has pilot bar bearing 11 up and down respectively, is fixed with spring 13, slider roller 14 through setting nut 12 on the pilot bar bearing; Also have moving voussoir 15 on the described pilot bar and decide voussoir 16, wherein there is the protruding wing below of moving voussoir 15.
Described pilot bar 17 supports through pilot bar bearing 11; 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 14.
Described bar and connecting rod are articulated on the frame through bearing pin 9.
Described key baffle plate is fixed on the frame through adjustment nut 7.
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 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: when the disconnected rope of haulage cable takes place, pull bar 1 drives bar 8 under the effect of retarding spring 6; 17 motions of connecting rod 10, pilot bar because pilot bar 17 and moving voussoir 15 weld togethers, thereby have driven the motion of moving voussoir 15; Bring moving voussoir into decide between voussoir 16 and the track wedge shape space; Because the angle of voussoir has self-locking property less than 2 times equivalent friction angle, thus the braking that has realized 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: we hope to brake car and do not play inhibition when traction winch draw, and when winch draw, the prosthomere mine car drove pull bar 1 through round-link chain and moves with respect to braking car; Pull bar 1 compression brake spring 6 also drives bar 8; 17 motions of connecting rod 10, pilot bar, thus will move voussoir take out of by track with decide the wedge shape space that piece is formed, and under the effect of spring 13 and slider roller 14; 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.
Braking key on the braking car does not only want to let braking car glancing impact just work in the transportation of inclined gallery, does not use generally speaking.
