The specific embodiment

Comprise the tractor truck 5, track scale 18 and the control setup that are located on the track 2, as shown in Figure 1, described tractor truck 5 lower ends are provided with two pulleys, a pulley connects the changed course mechanism 1 that is located at track 2 front ends through steel rope 4, another pulley connects driver train 7 through steel rope 4, described driver train 7 rear ends are provided with gravity takeup 8, and described driver train 7 is arranged vertically for 2 one-tenth with gravity takeup 8 and track, and connect tractor truck 5 through changed course pulley 14.

Described driver train 7 comprises variable-frequency motor, hard flank of tooth retarder, coupler and stepless rope friction drum, as shown in Figure 2.

Described changed course mechanism 1 is located at below the orbital plane.

The utility model comprises, (1) driver train 7, and it is made up of two variable-frequency motors, the hard flank of tooth retarder of two covers, coupler, the stepless rope friction drum of two covers; (2) gravity takeup 8, are made up of weight hammer type tensioning pylon, movement weight mass; (3) tractor truck 5, are made up of car body, train hook, counterweight, vertical changed course assembly pulley, inclination assembly pulley, set of wheels etc.; (4) changed course mechanism 1 is made up of trench, vertical pulley, horizontal pulley; (5) steel rope 4 and along Cheng Gaixiang pulley and Steel cable pulley 3; (6) safe limit switch and control system.

Embodiment: the utility model is that a kind of mode of traction of train railway carriage can also carry out the weighing of train railway carriage, special-purpose unloading hole unloading easily simultaneously.This draw gear is partly formed by six:

(1) driver train: driver train is made up of variable-frequency motor, hard flank of tooth retarder, coupler, stepless rope friction drum, its grooving number is by drawing formula calculating to get especially, unlikely to guarantee steel rope and mandrel surface that enough friction force are arranged skidding appears, also have four friction drums on the driver train, steel rope twines by certain method.See Fig. 2 actuating device and Figure 10.

(2) counterweighted take-up: counterweighted take-up is made up of pylon, weight, limit switch, this tensioning form is particularly reasonable to the long travel draw gear, but the elasticity of its automatic compensation steel rope, it is arranged in the back of system's machine room, and hauling rope arrives the tensioning pylon by friction drum, by arriving tractor truck again behind changed course pulley and the counterweight pulley, its stroke of tension is 5m, tower height 10.335m, 5 of counterweight weight are seen Fig. 3 counterweighted take-up.

(3) tractor truck: form by car body, train hook, counterweight, vertical changed course assembly pulley, inclination assembly pulley, set of wheels etc.See Fig. 4,5.

Car body is welded by shaped steel and steel plate, the long 6m of car body is furnished with No. 16 hitches and No. 2 spring boxs of railway special use, the finished product that wheel is bought by locomotive works, two leading sheaves are housed on the axletree, underneath its body is equipped with two inclination assembly pulleys, fills counterweight cement in the car body, rubble etc., be stamped gray iron counterweight above, safety guard net 17 be housed below the car body both sides.

The train coupler arranged railway standard hitch of selecting for use, hitch height of center (apart from rail level) 880mm, shock absorber is assembled into one on the hitch, and directly is fixed on the tractor truck girder, plays the effect of taking over from the past and setting a new course for the future.

Set of wheels is by wheel, axle, vertically alter course pulley, bearing seat etc. are formed, wheel adopts steel casting, diameter is a Φ 710mm single-wheel edge, vertical sliding wheel is used for the steel rope changed course, keep relatively rotating with axletree, the pulley of the band nyliner that spring ruins, the Zhenjiang anchor chain factory that pulley adopts Ministry of Communication to promote produces, this band nyliner pulley can improve steel rope one times～twice in service life.

Inclination pulley and chassis keep the inclination angle of 8 degree, are used for finishing the guiding action of tractor truck haulage cable multiplying power 2, and this pulley and vertical sliding wheel are identical product.

(4) changed course mechanism:

Changed course mechanism 1 is positioned at the front end of system, because railway interests's regulation and stipulation, equipment on the railway diatom can not surpass rail level 75mm, so changed course pulley (discrete pulley, the diameter of phi 710mm of terminal, horizontal diameter of pulley Φ 7100mm) must be below orbital plane, so increase a changed course trench, above-mentioned assembly pulley all be placed in the trench, for rain and snow, add a cover above, so just solved the problem of railway clearance.See Fig. 6,7.

(5) steel rope 4 with along the Cheng Gaixiang assembly pulley:

For steel rope 4 is not contacted with ground in the 420m stroke, establish one group of carrying roller 3 every 6m, (nylon carrying roller) it have in light weightly, and the resistance to abrasion height rotates characteristics such as flexible.

Changed course pulley 14 has vertical and horizontal two kinds, all is used for the usefulness that leads, and its structure and trench changed course pulley be same to go out a factory, all have nylon anti-wearing liner and other pulleys together with C/LOOP of steel rope formation.

(6) safe limit switch:

Native system safety limit switch comprises: the limit switch above the tightening device, prevent that weight from transfiniting up and down, establish a manual switch so that urgent need along journey every 50m in addition, at the tractor truck initial position is that terminal point is established a conductor near switch assurance tractor truck safety, establish a speed reducing switch so that tractor truck near the train railway carriage front reduction gear, is obtained big thrust by designing requirement with low speed in tractor truck the place ahead.Operating mode has operating switch at machine room, outdoor the Remote switch is arranged, and operates easily.

For safety, establish car bumper 10 at the end of track, to prevent the tractor truck derailing.

Aspect safety measure, except that equipment itself has been considered, be in collision with the train in order to prevent working truck, locate to establish safety barrier 16 and warning indicator lamp, siren etc. at the crossing etc. along journey.See Fig. 1 car stop 10, position-sensing switch 13.

Principle of work

Every line of tractor truck can draw 2500 tons of the fully loaded trailing weight of L18 traction engine 30 joints, after locomotive engine is pushed 30 joint heavy duties to unload fare to, locomotive engine breaks off relations and drives to marshalling station, the tractor truck tractor truck is run quickly to railway car with the speed of 0.5m/s and is gone like this, when near train, make tractor truck decelerate to 0.1m/s by frequency converter, knock the train hook and promote train and advance, No. 1 compartment is positioned at carries out the loaded vehicle metering on the track scale, No. 1 car metering finishes, tractor truck falls back to draw and carries out No. 2, No. 3, No. 4 compartment meterings, at last 1～No. 4 compartment is placed and carry out car unloading operation on the trench, 5～No. 8 then, 9～No. 12 ... all measure and unstow up to permutation 30 joint cars, at this moment the tractor truck go-cart of advancing again makes the 30th joint parking stall in the metering of the enterprising line space car of track scale, all measured up to 29～No. 1 cars, tractor truck breaks off relations and turns back to initial position with the speed of 0.5m/s and waits for next work cycle, sees Figure 10.
