Detailed description of the invention
A kind of section of track elevator for section of track lifting construction, as shown in Figure 1, 2, comprise the threaded screw rod hoist 1 arranged along section of track bilateral symmetry, every platform threaded screw rod hoist to be movably installed with between adjacent sleeper 2 and the lift carriage 4 stretched into below rail 3; As shown in Figure 3, lift carriage comprises installing plate 5, parallel two lifting brackets 6 being fixed on installing plate side, the location steel disk 8 that installing hole 7 is offered by center in two lifting bracket one end is connected as a single entity, threaded screw rod hoist is through installing hole, be fixed with slowspeed machine 9 above the installing plate of lift carriage, the output shaft of slowspeed machine is connected with the power intake of threaded screw rod hoist by belt and belt pulley 10; Lift carriage is fixed with rail outside the pressing plate 11 that fixes of base.
As shown in Figure 4, be provided with inside rail 3 with rail inside the edge of a wing carry out the position-limit mechanism that fixes, position-limit mechanism structure comprises the hinged spacing connecting rod 13 of the locating shaft 12 between being fixed in the middle part of two lifting brackets, middle part and locating shaft and the lead 14 be fixed in lift carriage and the back-moving spring 15 be sleeved on lead, back-moving spring upper end is connected with spacing flexible block 16, spacing small end and spacing flexible block are fixed, and spacing connecting rod lower end is free end.When lift carriage is placed on rail foot, artificial when inwardly or outwards promoting lift carriage, spacing flexible block blocks or departs from base inside rail under the effect of back-moving spring, and spacing connecting rod can be used for controlling the height that spacing flexible block ejects simultaneously.
Threaded screw rod hoist is trapezoidal thread screw structure turbine and worm drive mechanism, possess hoisting, decline function, mechanical caging, after the section of track needs stable elevation in transverse and longitudinal displacement situation, mechanical ascending and descending is adopted to have self-locking property, 25m long panel track about 22 tons, totally 20, double sided arrangements JWM150 type screw thread hoist, single lifting capacity 15 tons, stroke chooses 1100mm, and Integral lifting ability reaches about 200 tons.Threaded screw rod hoist is connected on belt pulley by slowspeed machine (2.2kw), adopts V belt translation transmitting torque, promotes hoist lifting.Threaded screw rod hoist adopts and is manually arranged on section of track both sides, 10, every side, equidistant layout, hoist is conducted oneself with dignity about 50kg, and can frequently carry, every side hoist is connected on 25kw generator 17, generator needs a dead lift, need to select deadweight light structure, conveniently frequently move, integral elevating speed 6mm/s.
Initial stage uses, and installs threaded screw rod hoist, belt pulley, slowspeed machine in lift carriage, and connect electrical control to generator, debug hoist, section of track both sides control respectively, can integral elevating, also can one-sidedly be elevated.Manually section of track elevator is seated to below the rail between two sleepers, headroom 290mm between two sleepers, hoist width 250mm, section of track elevator length considers the raised position of the standard section of track and track switch and the bridge place section of track, reduction length can adapt to different types section of track lifting needs.Lift carriage is placed on rail foot, inwardly promotes lift carriage, and make spacing flexible block block base inside rail, pressing plate fastens base outside track, and locking rail, prevents rail and lift carriage from throwing off.After both sides hoist installs, one-sided or bilateral hoists the section of track, at the uniform velocity stable lifting, to needs height, lay slide device, fall elevator, section of track entirety drops on slippage frame, spacing flexible block is put down, hoisting frame can throw off rail, manually remove elevator and generator, by section of track vertical shift or traversing, girder, longeron, hoisting cross beam, hoist cylinder, running mechanism is an entirety, crossbeam is installed on girder top, after putting in place, carrying elevator is to station, promote the section of track, remove slide device, elevator declines, drop on use station, take elevator and generator away, fill up the railway ballast adjustment section of track.Start the construction of next sections section of track after having good positioning, can work continuously.
