Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bridge shock absorption, and particularly relates to a bridge shock absorption and buffer base structure. Background Technique
[0002] A bridge generally refers to a structure erected over rivers, lakes and seas to enable vehicles, pedestrians, etc. to pass smoothly. To adapt to the modern rapidly developing transportation industry, a bridge is also extended to a building that spans mountain streams, poor geological conditions or meets other traffic needs to make passage more convenient. A buffer base is required at the lower part of the bridge to provide buffering.
[0003] Since the rubber leather seat in the buffer base is non-removable from the buffer seat after the conventional buffer base is installed, when the buffer rubber ages, it is very difficult to replace, resulting in the problem that it is very difficult to replace the aged rubber block in the conventional buffer base.
[0004] Therefore, we propose a bridge shock absorption and buffer base structure to solve the above problems. Content of the Utility Model
[0005] The purpose of the utility model is to solve the problem that it is very difficult to replace the aged rubber block in the conventional buffer base, and to propose a bridge shock absorption and buffer base structure.
[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0007] A bridge shock absorption and buffer base structure includes a top plate. A sliding column is fixedly connected to the lower end of the top plate. A sliding sleeve is slidably installed on the lower part of the sliding column. A guide seat is fixedly connected to the lower end of the sliding sleeve. A buffer leather block is clamped between the top plate and the guide seat. A threaded column is fixedly connected to the lower end of the side part of the top plate. A nut is externally threaded on the threaded column. A blocking block is slidably installed in the guide seat. A first bolt is slidably inserted through the blocking block. The lower part of the first bolt is threaded on the guide seat. A second bolt is threaded on the side part of the guide seat. The second bolt is in movable contact with the buffer leather block. After the device is installed, the second bolt is unscrewed and removed. When the buffer leather block ages and needs to be replaced, the first bolt is unscrewed, then the blocking block is removed, then the second bolt is screwed into the guide seat, and the nut is screwed downward so that the nut presses the guide seat downward. By using the upward action of the nut and the threaded column on the top plate, the pressure between the buffer leather block, the top plate and the guide seat is reduced, thereby reducing the resistance of the buffer leather block. The second bolt is screwed towards the buffer leather block to extrude the buffer leather block outward, and the buffer leather block is removed. Then a new buffer leather block is pushed between the top plate and the guide seat, and the new buffer leather block is driven between the top plate and the guide seat with a hammer. Then the blocking block and the first bolt are reinstalled, and the second bolt is unscrewed, which is convenient for replacing the buffer leather block.
[0008] Preferably, the guide seat includes a seat body and a threaded seat, and the lower end of the threaded seat is fixedly connected to the upper end of the seat body. After the second bolt is screwed, the second bolt moves spirally along the threaded seat, so that the second bolt can squeeze the buffer leather block, facilitating the removal of the buffer leather block.
[0009] Preferably, the guide seat further includes a threaded ring, and the threaded ring is fixedly connected to the threaded seat. The threaded ring is used to increase the threaded contact range of the second bolt.
[0010] Preferably, the buffer leather block includes a block body, and a guiding surface is provided at the upper edge of the block body. The guiding surface is used to facilitate the guiding of the block body into the space between the top plate and the guide seat.
[0011] Preferably, the nut includes a threaded knob and a threaded retaining ring. There are a pair of threaded retaining rings, and the threaded knob is fixedly connected between the two threaded retaining rings. By using a wrench to screw the threaded knob, the threaded retaining rings are driven to rotate, causing the nut to move spirally along the threaded column.
[0012] Preferably, the second bolt includes a threaded bolt body and a knob, and the knob is fixedly connected to one end of the threaded bolt body. By using a wrench to screw the knob, the threaded bolt body is driven to rotate, causing the threaded bolt body to move spirally along the threaded seat and the threaded ring.
[0013] Preferably, the second bolt includes a retaining ring, and the retaining ring is symmetrically and fixedly connected to the side of the knob. The second bolt is used to block the side of the knob to prevent the wrench from slipping off the knob.
[0014] In summary, the technical effects and advantages of the present utility model are as follows:
[0015] 1. After the device is installed, unscrew and remove the second bolt. When the buffer leather block ages and needs to be replaced, unscrew the first bolt, then remove the block, then screw the second bolt into the guide seat, and screw the nut downward, so that the nut presses the guide seat downward. By using the upward action of the nut and the threaded column on the top plate, the pressure between the buffer leather block, the top plate and the guide seat is reduced, thereby reducing the resistance of the buffer leather block. Screw the second bolt towards the buffer leather block to extrude the buffer leather block outward, remove the buffer leather block, then push the new buffer leather block into the space between the top plate and the guide seat, and use a hammer to drive the new buffer leather block into the space between the top plate and the guide seat. Then reinstall the block and the first bolt, and unscrew the second bolt, which is convenient for replacing the buffer leather block.
[0016] 2. After the second bolt is screwed, the second bolt moves spirally along the threaded seat, so that the second bolt can squeeze the buffer leather block, facilitating the removal of the buffer leather block. BRIEF DESCRIPTION OF THE DRAWINGS
