At the same time, there is a lack of fixed structure between the cross limiters, resulting in a single device being subjected to a large force that cannot be dispersed, causing damage, which is not conducive to actual application and operation. Utility Model Content

In the background technology, there is a lack of structure for limiting vertical displacement between the outer damper and the support shell of the device, so that the damper is shaken in the vertical direction during transportation, resulting in damage to the damper and inability to use it normally. At the same time, there is a lack of fixing structure between the cross limiters, resulting in a single device being unable to disperse a large force, thereby causing damage, which is not conducive to practical application and operation. Technical problems.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A shock-absorbing support mechanism for an overhead floor of an assembled subway station, comprising a bottom plate, a shock-absorbing cylinder is fixedly connected to the top of the bottom plate, a fixed column is arranged inside the shock-absorbing cylinder, a connecting block is arranged at the top of the fixed column, a mounting plate is fixedly connected to the top of the connecting block, a mounting bracket is fixedly connected to the top of the mounting plate, the mounting bracket is in a cross shape, fixing blocks are fixedly connected to both sides of the mounting bracket, fixing grooves are fixedly connected to both sides of the mounting bracket, the fixing grooves are used in cooperation with the fixing blocks, and a mounting floor is installed on the top of the four mounting brackets and located on the mounting plate;
[0008] A horizontal shock-absorbing component is arranged inside the shock-absorbing cylinder, and the horizontal shock-absorbing component is used to reduce vibrations in the horizontal direction. A vertical shock-absorbing component is arranged at the top of the fixed column, and the vertical shock-absorbing component is used to buffer vibrations in the vertical direction.
[0009] By setting the device to be fixed to the ground of the subway station, when the subway train is running, it will cause horizontal shaking to the nearby floor. When the device is subjected to horizontal shaking, the mounting floor will drive the mounting plate and the mounting bracket to shake. At the same time, the mounting plate will drive the connecting block to move slightly. The connecting block drives the fixed column to move within the limiting space of the sliding groove cooperating with the sliding rod. The fixed column is reset and shock-absorbed under the action of the horizontal shock-absorbing component. When the connecting block is subjected to a downward pressure, it will also shake at the same time. It is supported and shock-absorbed by the vertical shock-absorbing component. At the same time, when connecting the mounting brackets, the device is convenient and fast to install. During transportation, it avoids the separation of the fixed column from the shock-absorbing cylinder, thereby affecting the use effect. At the same time, the connection between the mounting brackets is more stable, which is convenient for dispersing the force received by a single support device, thereby increasing the overall service life and being beneficial to actual application and operation.
[0010] In a preferred scheme, the horizontal shock-absorbing component includes a return spring, a sliding rod, a sliding groove and a first damper. The sliding grooves are respectively opened at both ends on both sides of the fixed column and are horizontally perpendicular. The sliding rods are respectively slidably connected to the inner walls of the sliding grooves and are fixedly connected to the inner wall of the shock-absorbing cylinder. The return springs are respectively sleeved on both ends of the outer side of the sliding rod and are located between the inner wall of the shock-absorbing cylinder and the outer side of the fixed column. The first dampers are fixedly connected to both ends of the inner walls around the shock-absorbing cylinder, and one end of each first damper is fixedly connected to the outer side of the fixed column.
[0011] By setting when the subway train is running, it will cause horizontal shaking to the nearby floor. When the device is subjected to horizontal shaking, the mounting plate will drive the connecting block to move slightly. The connecting block drives the fixed column to move. The fixed column is reset by the reverse force generated by the first damper and the return spring. The sliding groove cooperates with the sliding rod to make the fixed column have a moving space when moving, so as to facilitate shock absorption and limit the movement of the fixed column in the shock-absorbing cylinder. Both the fixed column and the shock-absorbing cylinder are square.
[0012] In a preferred embodiment, the vertical shock-absorbing assembly includes a limiting groove, a limiting block, a second damper, and a shock-absorbing spring. The limiting groove is formed at the top of the fixed column. The limiting block is slidably connected to the inner wall of the limiting groove. The top of the limiting block is fixedly connected to the bottom of the connecting block. The second damper is fixedly connected to the bottom of the inner wall of the limiting groove and its top abuts against the limiting block. The shock-absorbing spring is sleeved outside the second damper and is located between the inner wall of the limiting groove and the bottom of the limiting block.
[0013] By setting that when the connecting block is subjected to a downward pressure, it will also generate shaking at the same time, and the second damper is used in cooperation with the shock-absorbing spring to support and buffer the downward pressure.
[0014] In a preferred embodiment, clamping members are fixedly connected to both sides of the fixed block. The clamping members are made of elastic plastic. Claw grooves are formed on both sides of the inner wall of the fixed groove. The claw grooves are used in cooperation with the clamping members.
[0015] By setting the clamping members in cooperation with the claw grooves, the stability between the fixed block and the fixed groove is increased. The fact that the clamping members are made of elastic plastic is beneficial to facilitating the entry of the fixed block into the interior of the fixed groove.
[0016] In a preferred embodiment, anti-slip pads are fixedly connected to the top of the mounting plate and around the mounting frame. The anti-slip pads are used in cooperation with the mounting floor. The anti-slip pads are made of rubber.
[0017] By setting the protection plate, the friction between the mounting plate and the mounting floor is increased, thereby preventing the mounting floor from being easily taken out, which affects the use. The rubber material increases its wear resistance.
[0018] In a preferred embodiment, fixing rods penetrate and are slidably connected to the four corners of the bottom plate. The fixing rods are fixed to the ground of the subway station. Anti-corrosion coatings are applied to the outer sides of the bottom plate and the shock-absorbing cylinder.
[0019] By setting the fixing rods in cooperation with the bottom plate, the device is fixed to the ground of the subway station. The anti-corrosion coating is beneficial to preventing the device from being corroded in a humid environment, thereby increasing the service life of the device.
