Abstract
The utility model provides rail pincers for maintaining yard rails. The rail pincers comprise two pincer claws, a connecting bolt and a rail clamping plate, wherein the two pincer claws are rotatable connected and fixed through the connecting bolt, the rail clamping plate is respectively fixed on the lower jaw of the two claws, and the upper portions of the two pincer claws are each provided with a top board, of which the upper portions are respectively provided with a hanger. The rail pincers for maintaining yard rails increase safety of the maintenance work and shorten maintenance time. The work had to be done by four persons in five days can be completed by three persons in half day, and the cost is reduced to 4330 yuan/vehicle from 41760 yuan/vehicle. The rail pincers for maintaining yard rails are reliable in structure, low in reconstruction cost, long in service lifetime, and unlikely to be damage and is energy-saving, environmental friendly and pollution-free. The problem that replacing a backing plate is time-consuming and risky during the process is solved.
Description
Technical field
The utility model relates to a kind of rail pincers for bridge track that keeps in repair.
Background technology
The general field bridge using, container in tire type crane mainly contains three great institutions, elevator, dolly, cart.Wherein the driving of trolley body completes by gear, tooth bar, and gear and tooth bar only play driving effect in trolley travelling, does not stress in the vertical direction, only output drive strength in the horizontal direction.
The support of dolly deadweight and lifting cargo weight is to be born by trolley track and dolly road wheel, and vertical forces whole on dolly are all on track and road wheel.
Because travel for a long time dolly road wheel and track contact-making surface of dolly has wearing and tearing, the dolly directly causing declines slightly, and wheel and rack gap reduces, and abnormal sound and vibrations, to tooth root portion, are caused in serious top when operation, have a strong impact on operating efficiency.Meanwhile, the set bolt of dolly tooth bar in use often can rupture, and the tooth bar cushion block of former car is solid " an iron pimple ", and the bolt of fracture fractures has 80% all can not get out inside.In conjunction with these two kinds of faults, adopt the adjustment of replacing backing plate to be convenient for changing highly again the cushion block of bolt.But only dolly single rack cushion block just has 41,82, full car, all changes cushion block and needs the 5 day time of 4 people, although can carry out by stages, also will stop 2 days at every turn, after 2-3 time, just completes.Though it is relatively simple to change the operation of a tooth bar cushion block, the cushion block quantity of every chassis is larger, and completing a chassis needs very large workload and maintenance cost, and each new cushion block cost of manufacture is that all changing is to calculate approximately to need 41760 yuan.
Within 2013, there are again many field bridges to occur this type of fault, change tooth bar cushion block by method for maintaining in the past, not only cost is high, and down time is long, to take personnel many, producing busy in the situation that at harbour 5 days is almost impossible by continuous field bridging parking, and bridge long maintenance, maintenance to other locomotives down time in separate unit field all can exert an influence.
Summary of the invention
For structural deficiency in prior art, the purpose of this utility model is to provide a kind of rail pincers for bridge track that keeps in repair, and is beneficial to reach safety, the efficient and low work on the spot demand of cost.
For achieving the above object, the technical solution adopted in the utility model is to provide a kind of rail pincers for bridge track that keeps in repair, wherein: this rail pincers includes two chelas, binder bolt, rail clamp, described two chelas are connected and fixed by binder bolt is rotating, rail clamp is separately fixed at the lower jaw of two chelas, top at two chelas is respectively equipped with top board, is respectively equipped with hanger on the top of top board.
Effect of the present utility model is the rail pincers that uses this maintenance field bridge track, increase the security of maintenance activity, reduced maintenance time, the work that need 4 people in past complete for 5 days is now as long as 3 people one and half can complete, and expense has reduced to 4330 yuan/car from the 41760 yuan/car in past.Rail pincers reliable in structure, the improvement cost of this maintenance field bridge track are low, long perfomance life, should not damage, energy-conserving and environment-protective are pollution-free, and the time while changing backing plate in the past of fundamentally having solved is long, have the problem of potential safety hazard in process.
Accompanying drawing explanation
Fig. 1 is rail pincers front view of the present utility model;
Fig. 2 is rail pincers side view of the present utility model;
In figure:
1, chela 2, chela 3, binder bolt 4, rail clamp 5, top board
The specific embodiment
The structure of the rail pincers to a maintenance of the present utility model bridge track is illustrated by reference to the accompanying drawings.
The rail pincers design philosophy of a maintenance of the present utility model bridge track is based on not changing tooth bar cushion block but at track lower padding iron plate, raises track and reach identical effect.Trolley track has been the top of bridge on the scene, according to the feature of rail section " work " font, in conjunction with the principle of tongs, has designed the rail pincers of special maintenance field bridge track.
The structure of the rail pincers of a maintenance of the present utility model bridge track is, this rail pincers includes two chelas 2, binder bolt 3, rail clamp 4, described two chelas 2 are connected and fixed by binder bolt 3 is rotating, rail clamp 4 is separately fixed at the lower jaw of two chelas 2, be respectively equipped with top board 5 on the top of two chelas 2, be respectively equipped with hanger on the top of top board 5.
On the rail pincers figure of a maintenance of the present utility model bridge track top hanger of two chelas 2 can be when operating hoisting transportation, coordinating 16 tons of hydraulic tops to support uses, each rail pincers is joined two hydraulic tops, each jack-up track need to arrange respectively a set of mechanism hydraulic top and withstand on top board 5 centre positions of two chelas 2 at track two ends, two hydraulic tops withstand on respectively the middle part of top board 5.Play hydraulic top, rail clamp 4, by after railway clamping, can reach the object of lifting.
Next plan is exactly preparation:
1, first the slippage of field bridge dolly gear is measured, is calculated the height 2mm that track need to be raised,
2, how simply to study, lift track efficiently, utilize tongs principle design to go out the specific purpose tool that can easily lift by crane track, rail pincers.
3, prepare 4 16 tons of conventional hand-hydraulic tops
4, backing plate being processed, be cut into and be slightly less than track width 110mm, is every 2 meters of * 108mm after completing, the backing plate after 2mm
Maintenance procedures:
1, use electric wrench segmentation pine rail pressing plate screw.
2, use special rail pincers and hydraulic top to coordinate track section jack-up.Jack-up 3-4mm, this deflection is in track elastic deformation.
3, backing plate is put into alignment, regains hydraulic top,
4, adjust track linearity.
5, fastening rail pressing plate screw.
Above-mentioned operation all completes 1.5 days total used times, and on personnel, only needs 3 people just can complete, and calculates by this operation:
1, rail pincers: 600 yuan/platform, 260 yuan/platform of hydraulic top, subtotal: 2240(belongs to maintenance tool and once drops into reusable)
2, backing plate: purchase 260 yuan/(1 meter * 2 meters), share 2,200 yuan of processing charges, subtotal: 740 yuan
3, artificial: 3 people, 1.5 days (300 yuan/people. day)
4, amount to: $4330
Adopt the relative original structure of method for maintaining of the rail pincers of a maintenance of the present utility model bridge track both to save cost, more saved maintenance time, to adjust now an expense used be original expense 1/10.Arrange properly to stop at operation gap and just can carry out.Need not employ electrogas welding, reduce potential safety hazard, provide condition for realizing safety in production simultaneously.
