Abstract
The utility model discloses an urban rail emergency evacuation ramp expansion buffer device, which comprises a bottom plate, a rubber pad, a compression spring, a guide post plate, a pressing plate, a sleeve and a connecting piece; the compression spring is arranged in the guide plate and is arranged between the bottom plate and the pressing plate; the sleeve is fastened on the pressure plate through a connecting piece; is arranged at the bottom of the foremost end of the emergency evacuation ramp. The emergency evacuation ramp has the advantages of simple structure and light weight, and can reduce vibration caused by contact collision between the ramp and the rail surface when the emergency evacuation ramp is completely unfolded.
Description
Technical Field
The utility model relates to a buffer especially relates to an urgent sparse ramp of urban rail expandes buffer.
Background
After the existing urban rail emergency evacuation ramp is unfolded, a buffer device is not arranged below the foremost end of the ramp, and the following problems exist: when the emergency evacuation ramp is deployed, the ramp will collide in contact with the rail surface. Without a damping device, such hard collisions would produce large vibrations and generate large noise.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: in order to solve the problems existing in the prior art, the utility model provides a reduce urgent sparse ramp of urban rail of vibration, noise and expand buffer.
The technical scheme is as follows: the utility model discloses a buffer device, which comprises a bottom plate, a rubber pad, a compression spring, a guide post plate, a pressing plate, a sleeve and a connecting piece; the compression spring is arranged in the guide plate and is arranged between the bottom plate and the pressing plate; the sleeve is fastened on the pressure plate through a connecting piece; the emergency evacuation ramp is arranged at the bottom of the foremost end of the emergency evacuation ramp; the bottom plate and the rubber pad are fastened on the emergency evacuation ramp through a connecting piece.
The rubber pad is located below the emergency evacuation ramp, and the bottom plate is located below the rubber pad.
The guide post plate is provided with a cylinder, and the compression spring penetrates through the cylinder and is arranged in the cylinder grooves of the bottom plate and the pressing plate.
The bottom plate and the rubber pad are connected and fastened with the emergency evacuation ramp through a connecting piece; the connecting piece passes through the hole of sleeve, the sleeve hangs on the connecting piece, can reciprocate.
Has the advantages that: compared with the prior art, the beneficial effects of the utility model are as follows: the emergency evacuation ramp has the advantages of simple structure and light weight, and can reduce vibration caused by contact collision between the ramp and the rail surface when the emergency evacuation ramp is completely unfolded.
Drawings
Fig. 1 is a schematic view of the deployment of an emergency evacuation ramp according to the present invention;
fig. 2 is a perspective view of the buffering device of the present invention;
fig. 3 is a right side view of the buffering device of the present invention;
fig. 4 is a sectional view taken along the direction a of fig. 3 according to the present invention.
Detailed Description
The technical solution of the present invention will be described in detail with reference to the drawings and the detailed description.
The emergency evacuation ramp is positioned at the front and rear vehicle heads of the urban rail vehicle and beside the cab. Buffer include bottom plate 11, rubber pad 12, compression spring 13, guide post board 14, clamp plate 15, hexagon socket head cap screw 16, sleeve 17, cross recess countersunk screw 18.
Fig. 1 shows an expanded schematic view of an emergency evacuation ramp of the present invention, which includes a buffer device 1, an emergency evacuation ramp 2, an emergency front door 3, and a head 4. The emergency front door 3 is mounted on the vehicle head 4. The emergency front door 3 is opened before the emergency evacuation ramp 2 is used. After the emergency evacuation ramp 2 is used, the emergency evacuation ramp 2 is firstly recovered into the vehicle body, and then the emergency front door 3 is closed.
Fig. 2 is a schematic structural diagram of the buffering device according to the present invention. The compression spring 13 is inserted into the cylindrical body of the guide pillar plate 14, and then the guide pillar plate 14 is inserted through the circular hole in the pressing plate 15. After the compression spring 13 is placed in the cylindrical hole in the base plate 11, the stud plate 14 is fastened to the pressure plate 15 with a cross-recessed countersunk screw 18. After the sleeve 17 passes through the inner hole of the pressure plate 15, the sleeve 17 is fastened on the pressure plate 15 by a cross-recessed countersunk head screw 18. Finally, socket head cap screws 16 are passed through the inner bores in the sleeves 17 and fasten the floor 11, rubber mat 12 together on the emergency evacuation ramp 2.
When an urban rail vehicle encounters an emergency, the emergency front door 3 at the position of the vehicle head 4 is opened, and then the emergency evacuation ramp 2 is unfolded. The buffer 1 is located at the bottom of the emergency evacuation ramp 2. When the emergency evacuation ramp 2 is fully deployed, the buffer device 1 contacts the rail surface below the emergency evacuation ramp 2 and activates the buffer function.
When the emergency evacuation ramp 2 is not in use, the compression spring 13 is in the normal state. When the emergency evacuation ramp 2 is fully deployed, the buffer 1 is in contact with the rail surface, and the function of the buffer 1 is activated. At this time, the compression spring 13 is in a compressed state. When the compression spring 13 is at the compression limit position, the rail surface will contact with the lower side of the rubber pad 12. At this time, the rubber pad 12 plays a secondary buffer role.
Buffer simple structure, light in weight, can effectively reduce the vibration that arouses because of the contact collision between ramp and the rail surface when emergency evacuation ramp expandes completely.
