Abstract

The utility model discloses a high-speed ejection buffering device which comprises a rubber band buffering unit, a sponge buffering unit, a spring buffering unit and a hydraulic buffering unit, wherein the sponge buffering unit is arranged between the rubber band buffering unit and the spring buffering unit; the spring buffering unit is positioned between the sponge buffering unit and the hydraulic buffering unit. The occupied length of the high-speed ejection buffering device is controlled to be within one meter, so that the occupied effective ejection length is small; a first-stage high-hardness sponge is used for decomposing preliminary collision stress; the speed of a trolley is reduced through graded action of a plurality of second-stage high-energy elastic rubber bands and third-stage high-intensity lengthened springs in sequence; the residual energy is finally absorbed through fourth-stage hydraulic stopping buffers to stop the trolley; the three steps can be instantly finished continuously through collision, speed reduction and stopping; the ejection trolley can be slowed down grade by grade within a short distance under a condition of extremely high speed till the ejection trolley is stopped and is prevented from being damaged; the buffering efficiency is high, and the stopping effect is good.

Description

Launch at a high speed damping device

Technical field:

The utility model relates to a kind of damping device, particularly relates to a kind of high speed and launches damping device.

Background technique:

Current high speed is launched in buffer system, what adopt is one pole buffer system, can not meet like this buffering requirement of launching at a high speed, have launch rear dolly and cannot stop or stopping after the shortcoming such as damage very easily, it is larger that common multi-buffer system takies length, and cost is higher.

Model utility content:

Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of high speed to launch damping device, can be continuously from clashing into, slow down, stop moment, complete this 3 steps, protection dolly stops not being damaged under hypervelocity condition.

The utility model is that the technological scheme that technical solution problem is taked is:

A kind of high speed is launched damping device, described high speed is launched damping device and is arranged on and launches on support body, described high speed is launched damping device and is comprised elastic buffer cell, sponge buffer cell, spring buffer unit and hydraulic cushion unit, between described elastic buffer cell and spring buffer unit, be provided with sponge buffer cell, described spring buffer unit is between sponge buffer cell and hydraulic cushion unit.

Described elastic buffer cell is comprised of many high energy elasticity elastics; Described sponge buffer cell is comprised of high-density hard sponge; Described spring buffer unit comprises that two high strength lengthen spring; Described hydraulic cushion unit comprises that two hydraulic pressure stop buffer.

Positive beneficial effect of the present utility model is as follows:

1, the utility model is integrated by many high energy elasticity elastics, high-density hard sponge, high strength lengthening spring and hydraulic pressure are stopped to buffer organic assembling in the length of 1 meter; can from clashing into, slow down, stop moment, complete this 3 steps continuously; protection is launched dolly moment under the condition of hypervelocity and is stopped and not being damaged; buffering efficiency is high, stops effective.

2, the utility model is decomposed and is just hit stress by first order high hardness sponge, by many of second level high energy elasticity elastic, third level high strength, lengthen spring gradation successively and be used for reducing little vehicle speed, by fourth stage hydraulic pressure stop buffer the most at last dump energy absorption it is stopped.

3, the utility model is because always take length and be controlled within 1 meter, takies that effectively to launch length little.

Accompanying drawing explanation:

Fig. 1 is structural representation of the present utility model.

Embodiment:

Below in conjunction with accompanying drawing, the utility model is further explained and explanation:

Referring to Fig. 1, a kind of high speed is launched damping device, described high speed is launched damping device and is arranged on and launches on support body, launching damping device comprises elastic buffer cell 1, sponge buffer cell 2, spring buffer unit 3 and hydraulic cushion unit 4 at a high speed, between elastic buffer cell 1 and spring buffer unit 3, be provided with sponge buffer cell 2, spring buffer unit 3 is between sponge buffer cell 2 and hydraulic cushion unit 4.Wherein, elastic buffer cell 1 is comprised of many high energy elasticity elastics 5, and sponge buffer cell 2 is comprised of high-density hard sponge, and spring buffer unit 3 comprises that two high strength lengthen spring 6, and hydraulic cushion unit 4 comprises that two hydraulic pressure stop buffer 7.

This model utility is passed through many high energy elasticity elastics, high-density hard sponge, high strength lengthening spring and hydraulic pressure stop buffer organic assembling in the length of 1 meter and are integrated, by first order high hardness sponge, decompose and just hit stress, successively by many of second level high energy elasticity elastic, third level high strength lengthens spring gradation and is used for reducing little vehicle speed, by fourth stage hydraulic pressure stop buffer the most at last dump energy absorb it stopped, can be continuously from clashing into, slow down, stopping moment completing this 3 steps, protection is launched dolly moment under the condition of hypervelocity and is stopped and not being damaged, buffering efficiency is high, stop effective.
