Description
Technical field
The present invention relates to electric locomotive brake field, related in particular to a kind of metal mine downhole electrical motor vehicle brake.
Background technology
Underground transportation system tractor equipment mostly adopts DC electric formula frequency control motor car, take 20t electric locomotive and 25t electric locomotive as main flow equipment, this kind equipment drives by DC machine, moment is delivered to wheel to walking through drop-gear box, drive the mine car drawing to carry out Ore Transportation, brake system is comprised of handwheel foundation brake, aerodynamic braking and electrical resistance braking.
Aerodynamic braking is mainly used in the brake snub of electric locomotive, brake shoe, lever system, brake cylinder, transverse arm etc., partly consists of.By pressurized air or manpower manual, make brake block closely connected with wheel rim or separated, thereby realize braking or the alleviation of system.
Handwheel foundation brake is mainly used in electric locomotive stopping brake, by rotation hand wheel, drives screw mandrel, makes that brake shoe is closely connected with wheel rim or separated carries out work, shares part braking principal organ with aerodynamic braking.
Electrical resistance braking is for speed limit, the deceleration of electric locomotive.Locomotive is when low cruise or emergency braking, and electrical resistance braking was used with the aerodynamic braking used time.
The existing brake equipment of electric locomotive as shown in Figure 2, by lever 11 and brake shoe 12, form one group of stop mechanism, connection wire rod 13, wheel 14, close wheel 14 1 sides of described screw mandrel 11 are fixedly connected with brake shoe 12, described brake equipment is provided with two groups of stop mechanisms, the bottom of the screw mandrel 11 of this stop mechanism is connected by connection wire rod 13, there are 3 large shortcomings in the brake mode of this device: 1, electric locomotive aerodynamic braking and handwheel foundation brake are all based upon 1 braking force and act on 2 wheels in front and back to upper by lever 11 and connection wire rod 13, and braking force source is unique; 2, lock torque is limited by cylinder in the installation dimension of electric locomotive inside, and piston rod thrust causes poor stop not, and electric locomotive can not brake in time; 3, brake block 12 give wheel on unilateral thrust can affect the straightness accuracy of wheel to axle, be also wheel to one of initiation reason of off-axis, wheel is produced to negative influence to the life-span, serious affects device security and produces smooth and easy.
Summary of the invention
The deficiency existing for prior art, object of the present invention is just to provide a kind of metal mine downhole electrical motor vehicle brake, solves the long problem of electric locomotive brake distance, eliminates the negative influence that in braking procedure, brake shoe causes axle Unidirectional acting force wheel.
To achieve these goals, the technical solution used in the present invention is such: a kind of metal mine downhole electrical motor vehicle brake, comprise lever, cylinder, brake shoe, first group of abnormity lever, first group of hinge-point, second group of abnormity lever, second group of hinge-point, unitor, the upper end of described lever is installed with cylinder, bottom is provided with brake shoe; One end of described first group of abnormity lever is connected with brake shoe, the other end is fixedly installed in first group of hinge-point; One end of described second group of abnormity lever is fixedly installed in second group of hinge-point, the other end is connected with brake shoe; Described lever bottom is connected by unitor with the bottom of second group of abnormity lever; Described brake shoe comprises brake shoe piece, brake head, and brake shoe piece is connected with brake head.
As a kind of preferred version, between described first group of abnormity lever, be provided with connecting panel, between second group of abnormity lever, be provided with connecting panel.
As a kind of preferred version, described unitor is connection wire rod.
As a kind of preferred version, described first group of hinge-point, second group of hinge-point are connected with the front and back dividing plate of electric locomotive respectively.
Compared with prior art, beneficial effect of the present invention:
1. 2 wheels before and after side, to separately braking, are separately controlled by 2 cylinders, solved and blocked or the problem of locomotive brakeless during crooked locking when cylinder piston rod;
2. right to changing 1 wheel of 1 Braking into by 2 wheels of 1 Braking, improve braking effect, reduce stopping distance;
3. eliminate wheel to the diametral load producing because of cylinder positive thrust, increased the friction force of wheel opposite side, braking effect obviously improves, and reduces the stopping distance of electric locomotive.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is original brake device structure schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
Embodiment:
As shown in Figure 1, a kind of metal mine downhole electrical motor vehicle brake, comprise lever 1, cylinder 2, brake shoe 3, first group of abnormity lever 4, first group of hinge-point 5, second group of abnormity lever 6, second group of hinge-point 7, unitor 8, the upper end of described lever 1 is installed with cylinder 2, bottom is provided with brake shoe 3; One end of described first group of abnormity lever 4 is connected with brake shoe 3, the other end is fixedly installed in first group of hinge-point 5; One end of described second group of abnormity lever 6 is fixedly installed in second group of hinge-point 7, the other end is connected with brake shoe 3; Described lever 1 bottom is connected by unitor 8 with the bottom of second group of abnormity lever 6; Described brake shoe 3 comprises brake shoe piece 9, brake head 10, and brake shoe piece 9 is connected with brake head 10; Between described first group of abnormity lever 4, be provided with connecting panel, between second group of abnormity lever 6, be provided with connecting panel; Described unitor 8 is connection wire rod; Described first group of hinge-point 5, second group of hinge-point 7 are connected with the front and back dividing plate of electric locomotive respectively.During concrete enforcement, lever 1 upper end has been installed cylinder 2 and has been formed separately independently braking force source, when electric locomotive need to be braked, cylinder 2 makes brake shoe 3 be close to wheel by lever 1, connection wire rod on lever 1 drives second group of abnormity lever 6 simultaneously, make it to rotate centered by second group of hinge-point 7, drive brake shoe 3 to be close to wheel simultaneously, form 2 groups of brake shoes, 3 encirclement wheel both sides and carry out bilateral braking, reach two objects: one, eliminate wheel to the diametral load producing because of cylinder 2 positive thrusts, two, increased the friction force of wheel opposite side, braking effect obviously improves, reduce the stopping distance of electric locomotive.Simultaneously between every group of opposite sex lever, design connecting panel, the cylinder 2 of same model carries out work under the effect of same source of the gas, form interlock, when any one cylinder 2 goes wrong, the cylinder 2 of opposite side passes over braking force by connecting panel, and braking when forming both sides wheel is avoided electric locomotive to slide down and even turned on one's side.
Finally it should be noted that, above embodiment is the non-limiting technical scheme in order to technical scheme of the present invention to be described only, those of ordinary skill in the art is to be understood that, those are modified or are equal to replacement technical scheme of the present invention, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of claim scope of the present invention.
