Abstract

The present invention provides a door opening and closing machine for a coal transport tank truck, which relates to matched equipment for a coal transport tank truck in a railway and performs an opening and closing function for a door leaf of the coal transport tank truck. The present invention belongs to the field of railway transportation. The present invention is matched with the coal transportation tank truck to be used and has the advantages that hundreds of thousands of tons of loss for coal transport in the railway can be reduced per year; the loss of a plurality of billions yuan RMB is reduced (the amount of the coal transport in the railway for the whole nation reaches 12.85 billion tons, the specified road loss is 1.2%, and the current coal price is more than 500 yuan per ton), and the present invention performs great functions for saving energy sources and reducing environment pollution. The present invention is mainly composed of an installation framework, a rotary arm, a pull rod, a hook head arm, etc., and by the rotation of the rotary arm, the pull rod is driven to push the door leaves of the tank truck to be open or close the door leaves.

Description

Coal transport tank truck open and close door machine

Technical field

The present invention is the corollary equipment of railway coal transport tank truck, and the door leaf of coal transport tank truck is played open and close, effect, belongs to railway transport field.

Background technology

Present coal railway transportation all adopts the open-top car transportation, this transportation mode loss is big, inconvenience is unloaded, for this reason, I have invented a kind of tank car transportation, and (applying for patent on January 1st, 2006) still, this tank car is when the coal bunker entrucking of colliery, need open and close the door leaf of tank car could operation in good time, for this reason customized design the supporting machinery of this open and close door leaf.

Summary of the invention

The present invention transforms the existing entrucking fortune coal measures system in colliery, and supporting open and close door machine is to be applicable to applying of coal transport tank truck.

Principle of work of the present invention is: utilize crankshaft-and-connecting-rod to combine, and supporting dead point cylinder holds connecting rod in good time, the rotation of bent axle is become the crank motion of connecting rod and lift and fall action design and form.Wherein the running diameter of pivot arm equals the length that door leaf will move, and pivot arm whenever rotates a circle, pull bar under the effect of dead point cylinder, finish once kick up, descending, fall, up action.Thereby utilize it to reverse and push door leaf when downward open, clockwisely shut door leaf upwards the time, leave doorframe when pull bar is kicked up, hold (or pushing away) doorframe when falling.Wherein hang on the base plate that backboard support is installed in coal bunker, underframe is installed in and hangs on the backboard support, reductor is installed on the underframe, deceleration arbor one end links to each other with motor shaft, (motor is fixed on the reductor) other end links to each other with pivot arm, rotary arm shaft is equipped with in outer end at pivot arm, links to each other with pull bar by axle sleeve, and the other end of pull bar links to each other with the gib head arm.At closing time, the rotation of pivot arm anticlockwise direction, the gib head arm hooks the rotation of the doorframe left side, and the drive door leaf moves to right and closes the door, when opening the door, switched in opposite, the gib head arm props up door leaf the right and is rotated down, and pushes door leaf open.When closing or opening door leaf and reach terminal point, an end of pull bar all can drag pull bar under the effect of dead point cylinder, makes the gib head arm leave doorframe, and when waiting next tank car to arrive then, descending again falling enters next circulation.

The specific embodiment

As shown in Figure 1, tank car D adopts movable loading, at one of coal bunker, a door opener is housed, a door engine is equipped with in the other end, when (door engine does not draw among the figure) enters coal bunker A as tank car D, at first open door leaf by door opener C, coal unloading hole B opens entrucking, and the coal among the coal bunker A enters tank car D by coal unloading hole B, install the back vehicle and enter under the door engine, shut car door by door engine.Be explained respectively below (annotate: entire work process is finished by weight house staff operation).

Door engine mainly contains compositions such as hanging backboard support 1, underframe 2, motor 3, reductor 4, deceleration arbor 5, pivot arm 6, rotary arm shaft 7, pull bar 8, pull bar cylinder 9, connecting pin 10, gib head arm 11, gib head roller 12, dead point axle 13, dead point cylinder 14, location column 15, column cylinder 16, support 22 shown in Fig. 2,3.Wherein hanging backboard support 1 is installed on the base plate appropriate location of coal bunker, underframe 2 is installed in and hangs on the backboard support, butt joint links to each other motor 3 with reductor 4 Both axles, reductor 4 is installed on the underframe 2, pivot arm 6 one ends vertically link to each other with deceleration arbor 5, the other end is equipped with rotary arm shaft 7, one end of pull bar 8 is fixedly linked by axle sleeve and rotary arm shaft 7, the other end is fixedly linked by connecting pin 10 and gib head arm 11, the left side at gib head arm 11, at least plural roller 12 is installed, the longitudinal frictional force when being used to reduce gib head arm 11 and contacting with doorframe 18.(length of pull bar 8 can be regulated) is at the interlude of pull bar 8, be set with pull bar cylinder 9, the friction force of up-and-down movement and column cylinder 16 when being used to reduce pull bar 8 runnings, below pull bar cylinder 9, be horizontally installed with dead point axle 13, the two ends of axle are fixed on the support 22 of special setting, and (support 22 is connected on the underframe 2) is on dead point axle 13, dead point cylinder 14 is housed, contacts the friction force of generation when being used to reduce pull bar 8 whereabouts with the dead point cylinder.Dead point axle 13 can be done the position adjustment of suitable upper and lower, left and right on support 22, be used to regulate the height that gib head arm 11 leaves doorframe 18.

Location column 15 is vertically mounted on the left side of pull bar 8, be fixed on the base of hanging backboard support, last cover column cylinder 16, column cylinder 16 contacts with pull bar cylinder 9 during running, effect is the application force that (arrow representative moving direction) brings pull bar 8 when overcoming tank car and moving, and makes pull bar 8 keep normal relatively position.

At closing time, pivot arm 6 moves to lower dead point position, and pull bar 8 reaches the end, gib head arm 11 falls, and roller 12 hooks the side of left-hand door frame 18, at this moment, pivot arm 6 is under the drive of motor 3, rotate up by reductor 4, it is up that (anticlockwise direction) passes through pull bar 8, gib head arm 11, the doorframe left side 18 spurs door leafs 17, when pivot arm 6 reaches first dead center, pull bar 8 is moved to the left and is at the end, door leaf 17 Close Alls, locating dowel pin 20 fall in the locating dowel pin hole 21, finish the process of closing the door.(Fig. 2 closes the door) pivot arm 6 continues rotation; pull bar 8 is descending; its left end is in low level, and the middle part is propped up by dead point cylinder 14, and right-hand member gib head arm 11 lifts; leave left-hand door frame 18; shut down this moment, when waiting next tank car to arrive, starts door engine pivot arm 6; make pull bar 8 be shifted to the right to the end, repeat above-mentioned action.

Door opener as shown in Figure 4, its structure is identical with door engine basically with principle of work, just pull bar 8 is made suitable lengthening, (roughly increasing by two width between doorframe) removes the roller on the gib head arm 11 12, is installed in the another side of gib head arm 11, promptly outer roller 23, during work, motor 3 rotates in the direction of the clock, and the outer roller 23 on the gib head arm 11 props up one side of right doorframe 19, pull bar 8 is descending, can push the door leaf 17 of car open.(Fig. 4 opens the door, the process of opening the door and the similar process of closing the door, just switched in opposite becomes and draws to pushing away, and no longer describes)
