Description
Technical field
The present invention relates to the stop devices of coaster in rocket sled test, especially rocket sled test.
Background technique
Brake in existing rocket sled test is hydromatic brake, umbrella brake, flaps brake and check cable brake.For big
The rocket powered sled of quality can reach brake purpose using elastic check cable in low speed.And for the coaster of small quality,
Small suspension type coaster in orbit is such as installed using idler wheel, since friction is small with track for it, is blocked using elasticity
The case where check cable reversely accelerates coaster is likely to occur after resistance rope brake.Therefore need a kind of device can be in coaster operation side
To guarantee, it is passed through, its movement is prevented when it is reversed acceleration, but there is presently no the methods for solving the problems, such as this.
Summary of the invention
The technical problems to be solved by the present invention are: a kind of one-way stop device is provided, it may ensure that coaster is just
It is passed through to traffic direction, prevents coaster from moving when check cable makes coaster inverted running.
The present invention is set forth above using solution by solving the problems, such as are as follows:
One-way stop device, it includes block, main shaft and support, and main shaft is arranged in outside the track of coaster by support,
The upper end of block and one end of main shaft are hinged；The main shaft is equipped with convex under for the convex platform of limit stop swing angle
Platform is fallen in the track-bound under block.
In above scheme, one-way stop device further includes rocker arm, pull rod and the crank for driving main axis, crank
One end is hinged with one end, and one end of rocker arm and pull rod are hinged.
In above scheme, pull rod is equipped with the clip for positioning to pull rod.
In above scheme, be additionally provided with the big boss for limiting main axis angle on the main shaft, support be equipped with it is big
The gear of boss cooperation.
The operation principle of the present invention is that: when sled test carries out, installation one-way stop device of the present invention in place, this
When block under the effect of gravity, under fall within the scope of pulley rail, coaster is in positive traffic direction one-way stop through the invention
When device, coaster impacts block, and block is swung up around main shaft, leaves in the track-bound, and coaster is in positive traffic direction
It passes through.It after the block of upper pendulum encounters convex platform, falls within the scope of pulley rail down, and obtains down convex under gravity
The support of platform, when check cable makes coaster stop simultaneously inverted running, since coaster speed at this time improves not yet, block can be under
Prevention coaster is back through stopping coaster under the support of boss.
It also have the advantage that
Multiple one-way stop devices of the present invention can be equipped in orbit simultaneously, each one-way stop device is joined by same pull rod
It is tied, after coaster stops, coaster is pushed to leave block certain distance, pull pull rod, pull rod drives each one-way stop dress
It the main shaft set while rotating, each lower convex platform pushes and puts away out pulley rail range on each block, and the reversible course of coaster passes through at this time,
Check cable is unloaded, coaster can smoothly be recycled to transmitting starting point.
When pull rod unclamps, block restores initial position under self gravitation effect, and steady brace can carry out next time
Rocket sled test.
Beneficial effects of the present invention: one-way stop apparatus structure of the present invention is simple and convenient to operate, is time saving and energy saving, reliability
Higher, cost is relatively low.In orbit when installation, multiple it can install, to ensure the coaster stop of different normal dangers.Meanwhile respectively
The distance between one-way stop device is adjustable, is not limited by installation site.By the adjustment to rocking bar and crank length, can be changed
Pull rod is suitable for a variety of different types of tracks at a distance from track and the reciprocating stroke of pull rod, therefore has very high
Application value.

Specific embodiment
Specific embodiments of the present invention are described in further detail below in conjunction with attached drawing:
One-way stop Installation practice of the present invention as shown in Figs 1-4, it include block 2, main shaft 4, support 5, rocker arm 7,
1 upper outside surfaces of track of coaster are arranged in by support 5 in pull rod 8 and crank 6 for driving main shaft 4 to rotate, main shaft 4.Such as
Shown in Fig. 5, main shaft 4 is installed on the carrier 4, is realized radial limit by rolling bearing, is realized axial limiting by retaining ring 16, together
When guarantee 4 flexible rotating of main shaft.The upper end of block 2 and one end of main shaft 4 are hinged, are fallen in 1 range of track under block 2；
As shown in fig. 7, the main shaft 4 is equipped with convex platform 10 and lower convex platform 13 for 2 swing angle of limit stop.
One end of crank 6 and 7 one end of rocker arm are hinged, and the other end and pull rod 8 of rocker arm 7 are hinged.As shown in fig. 6, on pull rod 8
Equipped with the clip 9 for positioning to pull rod 8,1 upper outside surfaces of track of coaster are arranged in clip 9.Pull rod 8 passes through clip 9, by
About 19 compression moulding bearing positions, and guarantees that it can flexibly be moved back and forth.
As shown in Fig. 1,7, the big boss 17 for limiting main axis angle is additionally provided on the main shaft 4, support 5 is equipped with
With the gear 21 of big boss 17 cooperation.
As shown in figure 5, one end of main shaft 4 is connect by pin 20 with crank 6, the other end is connected by bearing with block 2, with
Guarantee that block 2 can be around 4 flexible rotating of main shaft；Shaft end ring 15 is close to bearing, is connected by screw 14 with main shaft 4, plays limit
Effect.The lesser one end of crank 6 is connect by pin shaft 12 and bearing 10 with rocking bar 7, and split pin 11 is installed on the end of pin shaft 12,
Play position-limiting action.
When sled test carries out, block 2 is perpendicular to raceway surface, as shown in Fig. 1,5,8, convex platform 10 and lower convex platform 13
Distribution is used to the rotation of suitable course and inverse the course rotation (counterclockwise) of limit stop 2.The second rubber pad is pasted on lower convex platform 13
It is bonded, does not stress with the second rubber pad 18 when under the free plumbness of 18 block 2.First rubber pad 3 is close to convex platform 10, works as gear
2 rotational angle of block collides when reaching 135 ° with it, rotates for the suitable course of limit stop 2.Impact of the block 2 in coaster
Under coaster can be made to pass through around main shaft 4 along course rotation (state as shown in Figure 2) (clockwise), then in self gravity and
Whereabouts return (state as shown in Figure 1) under the recoil strength of one rubber pad 3.
When coaster inverse course movement under the action of elastic check cable, coaster encounters block 2, the lower convex platform 13 on main shaft
Block can be prevented to rotate with the second rubber pad 18, play the role of individual event stop.Coaster impact force passes through the second rubber pad 18
It is transmitted to main shaft 4 with the binding face of block 2, then support is transferred to by the gear 21 on the big boss 17 and support at 4 middle part of main shaft
5, it is finally transmitted to track 1, reduces impact of the coaster to apparatus of the present invention.
As shown in figure 3, test completion coaster needs to realize against course operation when recycling, loosens clip 9, pull pull rod 8, drawing
Bar 8 is parallel to track under a stretching force and moves against course, so that rocking bar 6 and main shaft 4 rotate clockwise under the pulling of crank 7
90 °, block 2 rotates 90 ° and is remained unchanged under the action of main shaft lower convex platform 13, and the inverse course of coaster is enable to pass through.
The present invention can not also set rocker arm, pull rod, crank, not set big boss on main shaft, main shaft is fixedly connected with support.It
For used aloned one-way stop device.
