In this embodiment, the support column unit 1 and the support leg unit 2 are made of materials with higher mechanical strength and extrusion resistance, and are generally made of 304 stainless steel materials, the support column unit 1 is assembled with a connecting part reserved by the motor frame a in a threaded or welded manner, the whole appearance of the support leg unit 2 is in a truncated cone shape, and a mounting groove is reserved in the middle for mounting the support column unit 1, so that the support column unit 1 can be fixed in the support leg unit 2 under the extrusion of the gravity of the motor frame a, and the buffer block unit 3 is arranged on the inner bottom surface of the central reserved groove of the support leg unit 2 and jacks up the support column unit 1 upwards, so that when the support column unit 1 receives the pressure from the motor frame a, the buffer block unit 3 is extruded to shrink, and the buffer effect on the falling instant of the motor frame a is realized.
The support column unit 1 comprises a support column 101 which is arranged on the support leg unit 2 and is used for jacking up the motor frame A; the support foot unit 2 includes a support block 201 provided on the support column 101, and a support column groove 202 provided on the support block 201 for mounting the support column 101; the buffer block unit 3 includes an air bag 301 provided on the bottom surface of the support column groove 202, and a support column spring 302 provided on the top surface of the air bag 301 and used for lifting up the support column 101.
In this embodiment, the supporting column 101 is made of a material with high mechanical strength and extrusion resistance, and is assembled with a connecting portion reserved for the motor frame a by screwing or welding, the appearance of the supporting block 201 is in a truncated cone shape, the supporting column groove 202 is arranged on the upper top surface of the supporting block 201, and the center of the opening circle coincides with the center of the upper top surface circle, so that the supporting block 201 is stressed and balanced, the air bag 301 is supported by an elastic material, and gas is filled in a central closed space formed by coating the elastic material, so that an "air spring" is formed, the elastic deformation degree of the air bag 301 is small, but the pressure resistance is good, the air bag can bear high pressure, when the supporting column 101 is pressed down, the supporting column spring 302 is first contracted, and when the supporting column spring 302 is contracted to a certain degree, the air bag 301 is pressed down, so that the air bag 301 is contracted, and a stepped buffering effect is formed.
The supporting leg unit 2 further includes a pressing block groove 203 provided on a side of the supporting column groove 202, and a pressing block spring 204 provided in the pressing block groove 203; the buffer block unit 3 further includes a pressing block portion 303 provided on the pressing block groove 203 for jacking up the side surface of the air bag 301.
In this embodiment, the pressing block grooves 203 are disposed on the lower side of the support column groove 202 at the same height as the air bag 301, one pressing block spring 204 is disposed in each of the support column grooves 202, and one pressing block portion 303 is disposed between the pressing block spring 204 and the air bag 301, when the air bag 301 is deformed by the downward pressing force of the support column spring 302, the air bag 301 extends to both sides, so that the side of the support column groove 202 is pressed, and if the support column groove 202, the pressing block spring 204 and the pressing block portion 303 are not disposed, there is a risk of the air bag 301 being pressed and exploded, and after the support column groove 202, the pressing block spring 204 and the pressing block portion 303 are disposed, the air bag 301 is supposed to extend to the side, and the pressing block portion 303 is pressed from the side to the inside of the support column groove 202, so that the entire space of the lower side of the support column groove 202 becomes larger, and the air bag 301 is expanded to a part, and the air bag 301 is prevented from being pressed and exploded.
In addition, the stiffness coefficient of the compression block spring 204 is higher than that of the support column spring 302, so that the air bag 301 is driven to deform only after the support column spring 302 is fully compressed, and the compression block spring 204 deforms to form a step-type buffering effect.
The supporting leg unit 2 further comprises a limit groove 205 arranged on the side surface of the extrusion block groove 203; the squeeze block portion 303 includes a squeeze block 303a provided on the squeeze block groove 203 for pushing up the side surface of the air bag 301, and a stopper plate 303b provided on the squeeze block 303a for engaging the stopper groove 205.
In this embodiment, the extrusion block 303a is easily dislocated during the movement of the extrusion block 203, which causes uneven stress with the air bag 301, and affects the buffering performance of the whole device, so that the upper and lower sides of the extrusion block 303a are respectively provided with a limiting plate 303b, and the upper and lower sides of the extrusion block 203 are respectively provided with a limiting groove 205 for clamping the limiting plate 303b, so that the extrusion block 303a can move along a straight line when moving into the extrusion block 203, thereby ensuring that the pressure applied to the air bag 301 is always kept uniform.
The pressing block portion 303 further includes a limiting plate opening 303c provided on the pressing block 303a for mounting the limiting plate 303b, a limiting plate opening ring 303d provided on the limiting plate opening 303c for sleeving the limiting plate 303b, a limiting plate ring 303e provided on the limiting plate 303b, and a limiting plate spring 303f provided between the limiting plate opening ring 303d and the limiting plate ring 303 e.
In this embodiment, the width of the extrusion block 303a and the limiting plate 303b is greater than the opening width of the extrusion groove 203, so that it is inconvenient to directly mount the limiting plate 303b in the limiting groove 205, so that a limiting plate opening 303c for conveniently moving the limiting plate 303b is mounted on each of the extrusion block 303a up and down, so that the limiting plate 303b can move up and down, and a limiting plate opening ring 303d is provided on the limiting plate opening 303c, and a limiting plate spring 303f is provided thereon for pushing up or down the limiting plate ring 303e provided on the limiting plate 303b, so that the limiting plate 303b is always in a pushed-out state without external force.
In addition, the end of the limiting plate 303b exposed to the outside is a circular arc end, so that the limiting plate 303b can be pressed into the limiting plate opening 303c by laterally pressing the circular arc end, so that the pressing block 303a can be conveniently installed into the pressing block groove 203, and when the pressing block 303a is installed into the pressing block groove 203, the limiting plate 303b protrudes from the limiting plate opening 303c under the action of the limiting plate spring 303f and finally is clamped into the limiting groove 205.
The pressing block portion 303 further includes a pressing column groove 303g provided on the pressing block 303a and communicating with the limiting plate port 303c, a pressing column 303h provided in the pressing column groove 303d, a connection string 303j provided on the pressing column 303e and used for connecting the limiting plate 303b, and a pressing column spring 303k provided on the pressing column groove 303g and used for jacking up the pressing column 303 h.
In this embodiment, the pressing post slots 303d are disposed at the central positions of the sides of the pressing blocks 303a, and are opposite to the central positions of the sides of the air bags 301, when the air bags 301 are installed between the two pressing blocks 303a, the sides of the air bags 301 press the pressing posts 303h into the pressing post slots 303g, at this time, the connecting ropes 303j are in a relaxed state, the limiting plates 303b are not pulled, the limiting plates 303b can be protruded and clamped into the limiting slots 205, and the overall technical effect is that when the air bags 301 press the pressing blocks 303a, the pressing blocks 303a can move linearly along the limiting slots 205.
In addition, after the air bag 301 is removed, the squeezing column 303h loses the squeezing action, and the squeezing column 303h protrudes outwards under the action of the squeezing column spring 303k, so that the connecting rope 303j pulls the limiting plate 303b inwards under the traction action to separate from the limiting groove 205, and the technical effect is that after the air bag 301 is taken out from between the two squeezing blocks 303a, the limiting plate 303b is automatically separated from the limiting groove 205, so that the air bag is convenient to detach.
The pressing block portion 303 further includes a steering column groove 303m provided on the pressing block 303a and communicating with the limiting plate port 303c and the pressing column groove 303g, and a steering column 303n provided in the steering column groove 303m and adapted to press the connection cord 303j to change the extending direction of the connection cord 303 j.
In this embodiment, the steering column groove 303m is disposed on the connecting portion between the limiting plate opening 303c of the extrusion block 303a and the extrusion column groove 303g, two ends of the steering column 303n are disposed on the side surface of the steering column groove 303m, the steering column 303n has a smooth arc-shaped side surface, and the connecting rope 303j extends out along the tangential direction of the steering column 303n and is connected to the bottom surface of the limiting plate 303b, so that the connecting rope 303j can pull the limiting plate 303b along the opening direction of the limiting plate opening 303c all the time, and the lateral pulling of the limiting plate 303b is effectively avoided to be blocked with the limiting plate opening 303 c.
The pressing block portion 303 further includes a pressing post plate 303p provided on the pressing post 303h and pushing up the airbag 301, and a post plate groove 303q provided on a side surface of the pressing block 303a and mounting the pressing post plate 303 p.
In this embodiment, the side surface of the extruding column 303h has a smaller area, so that the pressure to the air bag 301 is larger, and the air bag 301 is easy to be pricked and exploded, so that an extruding column plate 303p with a larger area is arranged on the side surface of the extruding column 303h, and the pressure to the air bag 301 is reduced.
In addition, after the extrusion column 303h completely enters the extrusion column groove 303g, the extrusion column plate 303p cannot enter the extrusion column groove 303g due to the large area, so that the airbag 301 cannot perfectly attach to the side surface of the extrusion block 303a, and the risk of explosion easily occurs due to the excessive local pressure of the airbag 301, so that the column plate groove 303q is disposed around the opening of the extrusion column groove 303g, and when the extrusion column 303h completely enters the extrusion column groove 303g, the extrusion column plate 303p also enters the column plate groove 303q, so that the airbag 301 perfectly attaches to the side surface of the extrusion block 303a, and the contact pressure is reduced.
The support column unit 1 further includes a support column spring groove 102 provided on the bottom surface of the support column 101 for mounting the support column spring 302, and a hanging piece 103 provided on the side surface of the support column spring groove 102 for engaging the support column spring 302.
In this embodiment, the support column spring groove 102 is provided to engage with the support column spring 302, and the suspension tab 103 is provided in the support column spring groove 102 to engage with the support column spring 302, so that the support column spring 302 will not disengage from the bottom surface of the support column 101 in the process of being compressed by an external force.
The bumper unit 3 further includes a spring washer 304 provided on the bottom surface of the support column spring 302 and adapted to jack up the airbag 301 downward.
In this embodiment, the bottom surface of the support column spring 302 is a steel wire ring, and the pressure generated by directly pressing the air bag 301 is too high, so that a spring spacer 304 is disposed between the support column spring 302 and the air bag 301, so as to reduce the pressure generated by pressing the air bag 301 by the support column spring 302.
The embodiments of the present invention have been described in detail, but the present invention is not limited to the above embodiments, and various modifications may be made without departing from the spirit of the present invention within the knowledge of one of ordinary skill in the art.
