Abstract
The utility model relates to a rail lifter which is composed of a bracket, a screw rod and a clamping apparatus, wherein the screw rod is arranged in the center of the bracket and forms a screw pair together with a screw hole on the top of the bracket, and the clamping apparatus is positioned between two supporting legs of the bracket. A clamping apparatus seat is arranged on the bottom end of the screw rod, and two jaws are installed on both sides of the clamping apparatus seat and are hinged with the clamping apparatus seat; the outer side of each jaw is connected with a guiding rod which is arranged in a guiding groove on the side surface of the bracket. The utility model has the advantages of simple structure, small size, light weight and convenient movement, and the jaws are driven to move up and down by rotating the screw rod, so the utility model can easily lift or lay down steel rails. The utility model also has the advantages of high work efficiency, low labor intensity and safe operation and is a practical rail lifter.
Description
Technical field
The utility model belongs to the mechanical lifting device, is specifically related to a kind of utensil that the seamless railroad rail promotes that is exclusively used in.
Background technology
The seamless track steel rail destressing is one of seasonal emphasis operation of railway department, and purpose is to make rail discharge internal stress.Diffuse the stress operation at present and be fastener, anticreeper is all or part of unclamps, and takes certain measure, make its rail break away from sleeper constraint and freely stretch, with the release internal stress.This operation need cut off traffic, block circuit, and labour intensity is big, and the engineering time is also long.Usually during operation, unclamp fastener, anticreeper after, need manually will to grow rail foot and lift certain altitude gradually with track jack, will roll then to shoulder and put into rail foot, make rail be in the state that freely stretches.When reaching the stroke of expection, with track jack rail is lifted again, take out rolling bar rail is locked again.This operational method must be lifted rail by a personal track jack, and another person places (or taking-up) rolling bar, and two people of the minimum needs of setting should take rolling bar again with heavy hydraulic track jack, and are time-consuming, inefficiency and dangerous.
Summary of the invention
The purpose of this utility model is to adopt mechanical device to substitute hydraulic track jack to promote rail, a kind of saving of labor is provided, saves time, labour-saving rail lifter.
Technical solution of the present utility model is: the rail lifter is made up of support, screw rod, jig; Screw rod is arranged on carriage center, forms screw pair with the screw of a top of the trellis; Jig is between two supporting legs of support, and the jig seat is arranged on the screw rod bottom, and two claws are installed in jig seat both sides, and claw is connected with jig seat hinge; Be connected with guide peg in the claw outside, guide peg is arranged in the gathering sill of support side.
During work, at first the rail fastening screw is unclamped, take out buckle and spring, then rail lifter bottom two card bases are stuck between the sleeper rail support groove; Be rotated down screw rod, claw opened move down and catch on rail head, rotate up screw rod then, make claw firmly grasp rail and rail is lifted; Again rolling bar is put under the rail, be rotated down screw rod and unclamp rail, make rail be in the state that freely diffuses.After diffusing end, rotate up screw rod once more rail is lifted, take out rolling bar, again rail is put down, elastic bar fastener to be tightened, operation finishes.
The utility model rail lifter is simple in structure, and volume is little, and is in light weight, moves very convenient.Rotation by screw rod drives the claw upper and lower displacement, can like a cork rail be picked up or put down.Adopt the rail lifter, made originally and must just can independently finish, save manpower and man-hour, improved operating efficiency, reduced labour intensity and cost of production, but also significantly improved the safety of operation by operation one people that two people cooperate.
Description of drawings
Fig. 1 is the structural representation of rail lifter;
Fig. 2 is the lateral view of Fig. 1.
Wherein: 1, screw rod six square toes 2, screw rod 3, support 4, jig seat 5, bearing pin 6, claw 7, guide peg 8, card base 9, gathering sill
The specific embodiment
As shown in Figure 1, support 3 has two supporting legs, and two outsides, supporting leg bottom respectively are provided with a card base 8.Screw rod 2 places in the screw at support 3 tops, forms screw pair.Jig seat 4 is sleeved on screw rod 2 bottoms, and rolling bearing is equipped with in screw rod 2 bottoms, and claw 6 is hinged by bearing pin 5 and jig seat 4.As shown in Figure 2, be connected with guide peg 7 in the outside of claw 6, guide peg 7 is arranged in the gathering sill 9 of support supporting leg side.
During use, available spanner plate moves screw rod six square toes 1, and screw rod 2 relative support 3 rotations make jig seat 4 drive two claws 6 and promote or decline, and guide rail is picked up or put down.Guide peg 7 upper and lower displacement in gathering sill 9 is played guiding and position-limiting action to claw 6.
Claims (2)
1, a kind of rail lifter is characterized in that being made up of support, screw rod, jig; Screw rod is arranged on carriage center, forms screw pair with the screw of a top of the trellis; Jig is between two supporting legs of support, and the jig seat is arranged on the screw rod bottom, and two claws are installed in jig seat both sides, and claw is connected with jig seat hinge; Be connected with guide peg in the claw outside, guide peg is arranged in the gathering sill of support side.
2, rail lifter according to claim 1 is characterized in that bottom the screw rod rolling bearing being housed.
