Problems solved by technology
However, the energy absorbed by the hydraulic buffer and the rubber buffer is limited. When the kinetic energy of the block is large, the block’s instantaneous impact on the tail end of the catapult is too large, and the structure of the block and the tail end of the catapult frame may be damaged.

Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0021] The invention provides a brake buffer device for a catapult, which is installed at the tail end 6 of the catapult. When the tackle slides in the catapult 6 and ejects the object to be ejected, the brake buffer device buffers the movement of the tackle , that is, during the braking process, the device provides a buffer force for the tackle. If the kinetic energy of the tackle after ejection acceleration is small, the buffer force provided by the hydraulic buffer is sufficient to buffer and brake the tackle. If the kinetic energy of the tackle is too large, use the shear pin to cut off the function to make the tackle, buffer and end baffle fly away from the ejection together. Device to prevent the catapult frame and tackle from being damaged.
[0022] Such as Figure 1~4 Shown is a specific structural schematic diagram of the p...

The invention provides a brake cushioning device for an ejector pulley, being installed on tail end of the ejector. The brake cushioning device comprises an end baffle plate, a hydraulic buff is installed in the middle of the end baffle plate, shear pin holes are arranged on both sides of the end baffle plate, pin holes respectively match with the shear pin holes are arranged on both sides of thetail end of the ejector, and the tail end of the ejector and the end baffle plate are fixedly connected through shear pins passing through the shear pin holes and the pin holes. Under a low-speed ejection condition, hydraulic buff brake cushion is carried out; under high-speed ejection condition, shear pins are cut off, that brake cushion device and a pulley depart from the ejector, effectively protecting the structure of the ejector frame and the safety of the pulley.
Description
technical field [0001] The invention relates to a brake buffer device, in particular to a brake buffer device for a trolley on a catapult. Background technique [0002] The catapult can accelerate the ejection load in a short distance by driving the pulley, and the accelerated high-speed pulley needs to achieve short-distance braking. At present, the technical solution is generally to install a hydraulic buffer or a rubber pad at the tail of the catapult as a terminal braking buffer. However, the energy absorbed by the hydraulic buffer and the rubber buffer is limited. When the kinetic energy of the block is very large, the impact of the block on the tail end of the catapult is too large instantaneously, and the structure of the block and the tail end of the catapult frame may be damaged. Contents of the invention [0003] In order to overcome the deficiencies of the existing terminal braking methods of catapults and to protect the safety of the frame structure, the prese...
