Background technology:

At present, the various parking slide-proof equipment kinds that use on railway line the home and abroad are a lot, as: skate, stop support, stopping device, automatic soling device etc.All be difficult to fixedly mount use on the circuit of intermediate station because of its a variety of causes, its major cause is that to can be used for installing the available space of fixed equipment between circuit and travelled by vehicle position very narrow, so be difficult to realize carry out product design and fixed installation use by needed barrier force, after particularly installing, safety problem is outstanding, as: what the anti-slip device product of the braking of skate, stop support etc. and so on relied on is that the lifting car body carries out the brake snub mode, can cause the off-line accident to the vehicle that passes through at a high speed; What rely on as: stopping device is brake mode to the wheel dry friction, and to outside extrusion technique condition is had requirement, so be difficult to the unrestricted friction force that improves stopping device, no person can cause the travelled by vehicle position to damage, and train operation accident occurs because of vehicle wheel.Above equipment also exists other corresponding problem simultaneously, as: installing transfinites, controls difficulty etc.So Above Transmission Lines does not have the applicable anti-slip device product of a kind of energy so far.From now on, equally do not have such can fixedly mount the fixing anti-slip equipment that uses in this interval abroad yet, more do not have mature technology to use for reference.

In view of the difficulty in the defective that exists on above-mentioned known technology and enforcement, our designer is according to the research and development experiences and practices of this respect for many years, for the problem of above-mentioned existence, in conjunction with the use of electromagnetism viscous know-why, fixedly controllable permanent magnetic slide-proof device of the present invention has been proposed.

Summary of the invention:

Content of the present invention mainly contains: 1. a plurality of trepannings that are provided with bottom the controllable permanent magnetic sucker, be sleeved on the top that slide plate is provided with skate and retracing spring one side, and make it do horizontal slip and to keep appropriate clearance by operation requirements and rail upper.2. every upper side of slide plate all is provided with skate and retracing spring, two also is provided with fixedly keyhole, can overlap hole count according to controllable permanent magnetic sucker bottom in use forms by many, every slide plate is respectively with laterally fixed installation on the line between two one steel rails bottoms two sleepers of fixed bolt, need not change existing railway line original base during installation, not occupy rolling stock clearance [for railway and track clearance after installation.3. the controllable permanent magnetic sucker is connected with solenoid-operated switch with drawing electric wire, produce adsorption affinity (magnetizing) or demagnetization in order to the Long-distance Control permanent magnet chuck to rail one side, the magnetic force that produces when magnetizing can make the gap of itself and rail reduce to stop it to pass through in order to the wheel that absorption is passed through to rail one side the sucker integral sliding, or demagnetization magnetic head demagnetization disappears its adsorption affinity, and the adsorption of removing wheel guarantees that vehicle can pass through smoothly.4. the retracing spring on slide plate after magnetic head demagnetization, can push away permanent magnet chuck wheel and strengthen magnetic head and the gap of rail, make permanent magnet chuck can by operation requirements be in all the time and rail between the position of reasonable clearance on, assurance vehicle, line security.

Major advantage of the present invention is, has simple in structurely, easy for installation, the controllable permanent magnetic sucker can be fixed on the inboard, station track with slide plate and operate control; Do not need the outside to provide the energy can produce long-term strong adsorption effect, energy-conserving and environment-protective; Principle of work rationally, it does not rely on the lifting vehicle or the wheel that rubs stops braking to vehicle, but rely on the effect of viscous principle that vehicle is braked, and has the good clear superiority of safety; But remote operation is controlled, and has convenience, flexible, the fast characteristics of response speed; Simultaneously it also have advantages of movable part few, should not damage, extensive management, easy to maintenance, good economy performance.
