Abstract
The invention discloses a cutting type anticreeper with a guiding pipe. The cutting type anticreeper comprises an anti-creeping toothed plate, the guiding pipe, a piece to be cut and a cutting component. One end of the guiding pipe is fixedly arranged on the anti-creeping toothed plate, the side wall of the guiding pipe is provided with a groove, and the guiding pipe is used for preventing bending in the impact process. The piece to be cut is arranged in the groove and used for being cut so as to achieve buffer and energy absorption when the impact force reaches a set threshold value. The cutting component is arranged at the other end of the guiding pipe in a sleeving mode, makes contact with the piece to be cut and is used for cutting the piece to be cut when the impact force reaches the set threshold value. Due to the fact that the guiding pipe and the piece to be cut are separated and the guiding pipe is made of high-strength materials, the problem that the integral rigidity is lowered due to the constraint of the piece to be cut is avoided, the vertical bearing capacity of the anticreeper can be greatly improved, and it is ensured that the buffer and energy absorption performance of the anticreeper is not affected on the premise that the anticreeper bears loads in the vertical direction. Meanwhile, the structure is simple, and the size of the anticreeper is reduced.
Description
Technical field
The present invention relates to crash energy absorption equipment technical field, in particular a kind of cutting type anti-creeper with guide pipe.
Background technology
Along with the develop rapidly of high ferro, subway, the trip that convenient, efficient track traffic has become many people is first-selected, and the safety precaution problem meanwhile brought also becomes and can not be ignored.When there is no safety precaution, once have an accident, the train in traveling as high-speed cruising large mass body entrained by huge kinetic energy will moment with other forms of energy dissipation, huge property damage and personal casualty can be caused.Thus how to extend the energy dissipation time, and at short notice a large amount of kinetic energy absorption is just become passive security and protect the difficult problem that must capture.In metal cutting process workpiece plastic deformation, to break and workpiece and cutter friction can at substantial energy, therefore have part-structure form to be exactly the effect utilizing this principle to complete energy-absorbing buffering in existing energy absorption device.
A train of vehicles can be caused to ride the dangerous situation climbed in another train of vehicles in the collision of actual condition Train, therefore the top priority of anti-creeper will avoid analogue to occur, this just requires that anti-creeper normally can work when bearing lateral loading.Pipe is cut as also playing the effect of bearing lateral loading while energy-absorbing original paper in tradition cutting type anti-creeper, often lower for ensureing to be cut the material yield strength of pipe selected by cutting energy-absorbing stablizes, so the existence of lateral loading just requires that being cut pipe has larger external diameter or thickness, which increases the volume of anti-creeper.
And existing cutting type anti-creeper structure is not by energy-absorbing function and bending resistance directional tagging separately, is cut part and selects homogenous material to be cut also will to bear lateral loading.In actual condition, for ensureing that energy-absorbing effect is stable, conformability is good, often intensity is lower for the part material that is cut selected, but impacting the vertical force brought can reach tens of ton, under the situation that installing space is limited, just require that the strength of material of energy absorbing tube is very high, contradicts between both.
Therefore, prior art has yet to be improved and developed.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of cutting type anti-creeper with guide pipe, solve anti-creeper in prior art for ensureing that the material yield strength being cut pipe selected by cutting energy-absorbing stablizes is often lower, so the existence of lateral loading just requires that being cut pipe has larger external diameter or thickness, which increases the volume of anti-creeper, not by defect that energy-absorbing function and bending resistance directional tagging separate.
