Pin hole, ejector tail end and end stop are fixedly connected by passing through shear pinhole with the shear pin of pin hole.
The end stop two sides are additionally provided with bar shaped key, the key that the setting of ejector tail end two sides cooperates with bar shaped key respectively
Slot.
The shear strength of the shear pin is less than the frame body bursting stress of ejector and the maximum cushioning power of hydraulic bjuffer.
Mounting bracket is fastened with by fastening bolt in the middle part of the end stop, hydraulic bjuffer, which passes through, to be fixedly mounted
Bracket.
Shear pinhole and pin hole on the two opposite medial surfaces in the end stop two sides and ejector tail end are at least
Including two, shear pin is connected in the shear pinhole and pin hole that are correspondingly arranged, multiple shear pins have different shear strengths.
The utility model has the beneficial effects that
(1) high reliablity: low speed launches hydraulic bjuffer braking buffering under operating condition, and shear pin is cut under high speed ejection operating condition
Disconnected, brake buffer unit flies away from ejector together with coaster, effectively protects the safety of ejector frame structure and coaster.
(2) structure is simple: ingenious in design, part is few, and processing cost is low, is readily produced manufacture.
(3) applicability is good: shear force value is adjustable, is applied in combination with the shear pin of different size, and it is strong to be suitable for different structure
The ejector of degree.
(4) easy to maintain: maintaining method is simple, at low cost, only needs to change the shear pin cut.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
The utility model provides a kind of ejector brake buffer unit, which is installed on ejector tail end 6, when coaster exists
It is slided in ejector 6, after needing the object launched to launch away, brake buffer unit buffers the movement of coaster, i.e.,
In braking process, which provides cushion effect for coaster.If the coaster kinetic energy after ejection accelerates is smaller, hydraulic cushion is provided
Cushion effect be enough to carry out buffer-braking to coaster, if coaster kinetic energy is excessive, using shear pin shearing function, make coaster, buffering
Device and end stop fly away from ejector together, and ejector frame body is prevented to be damaged with coaster.
It is a kind of specific structural schematic diagram of the utility model as shown in Fig. 1 ~ 4.I.e. as shown in Figure 1, the utility model
Buffer brake device include end stop 1, there is hollow hydraulic bjuffer mounting hole 8, hydraulic cushion in the middle part of end stop 1
Device 3 is mounted on the middle vacancy of end stop 1, and 1 two sides of end stop are provided with shear pinhole 7, the setting point of 6 two sides of ejector tail end
The pin hole 11 not cooperated with shear pinhole 7, ejector tail end 6 and end stop 1 are by passing through cutting for shear pinhole 7 and pin hole 11
Pin 2 is cut to be fixedly connected.
As shown in Fig. 1 and Fig. 3, Fig. 4, for convenience of the installation of ejector tail end 6 and end stop 1,1 two sides of end stop are also
It is provided with bar shaped key, the keyway 10 with the cooperation of bar shaped key, ejector tail end 6 pass through keyway to the setting of 6 two sides of ejector tail end respectively
After 10 cooperation and end stop with bar shaped key is installed together, shear pinhole 11 is docked with the pin hole 7 of end stop two sides, and
Brake buffer unit is fixedly mounted on ejector tail end 6 by shear pin 2, after shear pin is cut, keyway 10 can also be to winged
From end stop 1 play certain guiding role.
For the safe operation for guaranteeing buffer unit, the shear strength of shear pin 2 needs to be less than the bursting stress of ejector frame body
And the maximum cushioning power of hydraulic bjuffer.
As shown in Figure 1, passing through fastening bolt 5 and spiral shell in the middle part of end stop 1 to increase the stability maintenance of hydraulic bjuffer
The cooperation of keyhole 9 is fastened and fixed mounting bracket 4, and hydraulic bjuffer 3 passes through mounting bracket 4.
End stop two sides are disposed with the pin hole 7 of different size, and there is hydraulic bjuffer positioning hole in baffle center position
8, surrounding bolt hole 9 is used for mounting and fixing bracket 4.
Shear pinhole 7 and pin hole 11 on the opposite medial surface in 1 two sides of end stop and 6 two sides of ejector tail end are at least
Including two, that is, two pairs, and the sample diversified in specifications of two pairs of pin holes are included at least, so that being connected to different shear pinhole 7 and pin
Shear pin 2 on hole 11 has different shear strengths, by selecting suitable hydraulic bjuffer model and reasonable shearing pin bank
Configuration is closed, the safety of ejector frame structure can be protected to the greatest extent.When the shearing pin connection of different number and specification, two sides
Connection type keep symmetrical.
The entire braking buffering embodiment process of the utility model is as follows: ejector tail end 6 is with buffer unit by cutting
After cutting pin connection together, coaster rushes at end stop 1 with certain ejection speed, and hydraulic bjuffer buffers it, if sliding
Vehicle kinetic energy is excessive, and cushion effect makes coaster, buffer and end stop one take off more than certain value using shear pin shearing function
From launcher, coaster and launcher is prevented to be damaged.
