Abstract
The present invention relates to a safety stop apparatus suitable for stopping a vehicle in a vehicle unloading system of a tilting machine so as to prevent a railroad vehicle from falling into a machine pit or bumping into other devices. The stop apparatus is orderly provided with a front positioning sealing barrier, a back positioning sealing barrier, a push gear block and positioning nuts along an axis direction of a push rod, wherein the push rods between the front and the back sealing barriers and between the front sealing barrier and the push gear block are sheathed with springs. The push gear block fixed to the push rods is engaged with a gear which drives a transmission shaft to rotate; both ends of the transmission shaft are respectively provided with a piece of stop iron which faces the inner surface on one side of a guide rail and is provided with a convex stop block corresponding to a side opening of the guide rail. The stop iron rotates between a rising limited stop block and a falling limited stop block. The front and the back sealing barriers are arranged on a fixed frame. The safety stop apparatus overcomes the defects existing in a high derailment surface of the existing non-return apparatus and the existing one-way stop apparatus, and can be arranged below the surface of the guide rail. The safety stop apparatus satisfies the requirement of a criterion of a railroad department that the stop apparatus is not higher than a rail surface by 50mm when a vehicle passes by the safety stop apparatus, and also satisfies the requirement that the pedaling surface of a wheel is used as an action point.
Description
[technical field] the present invention relates to a kind of safety backstop apparatus, is particularly useful for being used in the tipper unloading system backstop vehicle, to prevent that rolling stock from falling into machine and cheating or bump against on the miscellaneous equipment.
[background technology] tipper unloading system is a kind of high-efficiency automatic operating system that steel mill, power plant, harbour etc. are located that is widely used in.In tipper unloading system, in order to prevent that rolling stock from falling into the machine hole or bumping against miscellaneous equipment, must be provided with holdback and unidirectional backstop apparatus, existing holdback act on wheel rim, except that pressure wheel excessively, all the time exceed rail level 140mm, existing unidirectional backstop apparatus acts on wheel tread, exceeds rail level 150mm all the time.Because the place in operation of railway 8 (changing) bogie truck, the gauge that will show of new Ministry of Railways's standard has changed the above 50mm of rail level into now, and active position do not allow for wheel rim, owing to above reason, and the use that has been under an embargo of former holdback and unidirectional backstop apparatus.
[summary of the invention] the object of the present invention is to provide a kind of safety backstop apparatus, this backstop apparatus not only can be used as holdback but also can make unidirectional backstop apparatus, backstop apparatus is not higher than the boundary requirement of rail level 50mm when having satisfied car excessively, and having satisfied point of action again simultaneously is the requirement of wheel tread.
The objective of the invention is to realize by following technological means.
A kind of safety backstop apparatus, it is characterized in that said backstop apparatus is disposed with the block of forward and backward location, promotes tooth piece and locating sleeve along the push rod axis direction, be set with spring on the push rod between the forward and backward block, be set with compression spring on the push rod between preceding block and the promotion tooth piece, be fixed on promotion tooth piece and gear mesh on the push rod, the gear drive transmission shaft rotates, and axle is equipped with buting iron.In order to guarantee the backstop apparatus stress equalization, a buting iron should respectively be equipped with at the two ends of above-mentioned transmission shaft, and is provided with and the corresponding protruding block of rail-sides opening towards guide rail one side inner face at buting iron, and buting iron is rotated between the positive stop rising and falling.Above-mentioned forward and backward block is installed on the fixed mount.
Safety backstop apparatus provided by the present invention is applicable to be used for the backstop vehicle in the tipper unloading system, to prevent that rolling stock from falling into machine and cheating or bump against on the miscellaneous equipment.This backstop apparatus has overcome existing holdback and unidirectional backstop apparatus exceeds the existing shortcoming of rail level, can be arranged on below the guide pass, satisfied the boundary requirement that backstop apparatus when Ministry of Railways's standard is crossed car is not higher than rail level 50mm, having satisfied point of action again is the requirement of wheel tread.
Introduce the present invention in detail below in conjunction with accompanying drawing.
[description of drawings] Fig. 1 installs and uses structural representation for the present invention;
Fig. 2 is that Figure 1A is to keeping off a car the status architecture scheme drawing;
Fig. 3 is that Figure 1A is to crossing car status architecture scheme drawing;
Fig. 4 is that Figure 1B-B is to the structure cutaway view.
[specific embodiment] as shown in the figure, this safety backstop apparatus is disposed with forward and backward location block 9, promotes tooth piece 2 and locating sleeve 10 along push rod 1 axis direction.Be installed between the forward and backward block 9 on the fixed mount 12 and be set with spring 6 on the push rod 1, be set with compression spring 7 on the push rod 1 between preceding block 9 and the promotion tooth piece 2, promote to be set with recoil spring 15 on the push rod [1] between tooth piece 2 and the locating sleeve 10.Be fixed on promotion tooth piece 2 and gear 3 engagements on the push rod 1, gear 3 drives transmission shaft 11 rotations that a buting iron 4 respectively is equipped with at two ends.Buting iron 4 is provided with and the corresponding protruding block 14 of rail-sides opening near the guide rail side, makes buting iron in the rotation between the positive stop 13 of rising and falling.
The principle of work of safety backstop apparatus is: promote push rod 1 by transfer platform 5, drive slide teeth piece 2 on the push rod 1, gear 3 drives buting iron 4 rotations and is used to keep off a car, crosses car.When transfer platform 5 leaves weight, empty wagons line: promote push rods 1 by spring 6 and drive 3 rotations of tooth piece 2 driven wheels, make buting iron 4 be in the state of keeping off a car that lifts; When transfer platform 5 walks to weight, empty wagons line: when not having wheel 8 to lean against on the buting iron 4, transfer platform 5 will promote push rod 1 drive buting iron 4 and set level car, when on the buting iron 4 wheel 8 being arranged, transfer platform 5 will promote push rod 1, compression spring 7, after treating that car puller promotes vehicle, spring 7 can promote buting iron 4 and set level car.
