Abstract
The invention discloses a reinforcing mechanism for a mining car. The reinforcing mechanism mainly comprises a steel wire rope a, a support plate, a cylindrical reinforcing device, a reinforcing rod a, a reinforcing rod b and a reinforcing rod c, and is characterized in that: a looped link is arranged on the support plate, and is connected with the front end of the steel wire rope a; the steel wire rope a is wound on the inner cylinder of the cylindrical reinforcing device; the cylindrical reinforcing device is arranged on the support plate; one end of a steel wire rope b is wound on the outer cylinder of the cylindrical reinforcing device, and the other end of the steel wire rope b is connected with the reinforcing rod a; the reinforcing rod a is hinged on the support plate through a bolt a; the reinforcing rod b is hinged with the reinforcing rod a through a bolt b; and the reinforcing rod c is hinged with the reinforcing rod b through a bolt c, and is hinged on the support plate through a bolt d. The mechanism is arranged in front of a holding claw, so that the braking force can be increased, and the braking time can be shortened.
Description
Technical field
Patent of the present invention relates to a kind of mine car and uses force-increasing mechanism.
Background technology
Existing automatic anti-running-away mine car workpiece principle is behind mine car generation sport car, to send overspeed signal through the hypervelocity induction installation; Mine car is braked, and brake equipment is divided into inserting grab and embraces two kinds of rail formulas, and inserting grab is to adopt to collude pawl and catch on sleeper; Reach the purpose of braking, this mode is convenient and simple, but only is adapted to the tunnel of sleeper; Compare with inserting grab, embrace rail formula brake equipment and have the prospect of using more widely, but existing armful of rail formula brake equipment only depends on the friction of embracing pawl and track to come consumed energy; Need bigger braking force, and braking time is longer.
Summary of the invention
Need big braking force, the long shortcoming of braking time in order to overcome the existing rail formula brake equipment of embracing, the present invention has designed a kind of mine car and has used force-increasing mechanism, and this mechanism is installed in embraces the pawl front, can amplify braking force, shortens braking time.
The technical scheme that the present invention adopts is: a kind of mine car is used force-increasing mechanism, mainly comprises steel rope a, stay bearing plate, cylinder booster; Reinforcement bar a, reinforcement bar b and reinforcement bar c is characterized in that shackle is installed on the stay bearing plate; And link to each other with steel rope a front end, steel rope a is on the interior cylinder of cylinder booster, and the cylinder booster is installed on the stay bearing plate; Steel rope b one end is on the outside cylinder of cylinder booster, and the other end links to each other with reinforcement bar a, and reinforcement bar a is hinged on the stay bearing plate through bolt a; Reinforcement bar b is hinged through bolt b and reinforcement bar a, and reinforcement bar c is hinged through bolt c and reinforcement bar b, and is hinged on the stay bearing plate by bolt d.
Body diameter is greater than the outside cylinder diameter in the described cylinder booster.
Bolt a on the described reinforcement bar a is positioned at an end of being partial to reinforcement bar b.
Bolt d on the described reinforcement bar c is positioned at an end that deviates from reinforcement bar b.
Shackle of the present invention is used for input brake power, when braking force pulling steel rope a travels forward, because the cylinder booster is a double-decker; And the internal layer circular diameter is greater than outer circular diameter, and amplification multiple is the ratio of interior circular diameter and outside diameter, so steel rope is through behind the cylinder booster; Braking force can amplify certain multiple, because the bolt a on the reinforcement bar a is positioned at an end of being partial to reinforcement bar b, so reinforcement bar a is a boosting lever; Bolt d on the reinforcement bar c is positioned at an end that deviates from reinforcement bar b, so reinforcement bar c also is a boosting lever, therefore; Braking force passes through further to amplify behind reinforcement bar a, reinforcement bar b, the reinforcement bar c; After braking force increased, the friction lining on armful pawl and the friction force of track increased, and braking time shortens.
Description of drawings
A kind of mine car of Fig. 1 is used the force-increasing mechanism assembly drowing.
The specific embodiment
Embodiment
Be installed in the cylinder booster on the stay bearing plate, stay bearing plate be welded on mine car bottom, with steel rope a one end on the interior cylinder of cylinder booster; The other end links to each other with shackle, and on the outside cylinder of cylinder booster, the other end links to each other with reinforcement bar a with steel rope b one end; Reinforcement bar a is hinged on the stay bearing plate through bolt a, and reinforcement bar b is hinged through bolt b and reinforcement bar a, and reinforcement bar c is hinged through bolt c and reinforcement bar b; And be hinged on the stay bearing plate by bolt d, with the lower end of reinforcement bar c with embrace a pawl and link to each other, behind the generation sport car; Speed sensor pulling shackle travels forward, and produces braking force, after braking force process cylinder booster and boosting lever a, boosting lever c amplify; Pawl is embraced in pulling, and the friction force of friction lining and track is increased, and shortens braking time.
