Description

Floor pipeline damping device

Technical Field

The invention relates to a device which is arranged at a hole of a floor slab and is used for damping a pipeline passing through the floor slab.

Background

When pouring is carried out on the building floor, in order to reduce the vibration in the pumping process of the pump pipe, a damping device is usually required to be arranged at the position of the pipeline. Current floor pipeline damping device is including cladding casing outside the pipeline and installing the spring between casing and pipeline, and the spring that a plurality of levels set up distributes around the pipeline. The installation of the device needs to pre-embed expansion bolts at the reserved hole of the floor slab, then the expansion bolts are fixed on the floor slab, and the damping and buffering are realized through the deformation of the spring during vibration.

Although the floor pipeline damping device can realize certain damping, the expansion bolts are extremely inconvenient to embed, and secondary damage to the floor slab is easily caused; in addition, the springs are additionally arranged on the periphery, so that the installation firmness is poor, the damping capacity is poor, the vibration force in the vertical direction cannot be effectively converted, and a large part of the vibration force in the horizontal direction can be transmitted to the floor slab through the expansion bolts, so that the concrete of the floor slab is damaged.

Disclosure of Invention

The invention aims to provide a floor pipeline damping device with a better damping effect so as to better protect a pipeline.

The floor pipeline damping device comprises a pipe pad sleeved outside a pipeline, wherein two ends of the pipeline respectively extend to two sides of a floor slab and are fixed on the pipeline through fastening components; a plurality of spring group is installed along the circumference of pipeline between shell and the tube pad, and every spring group all includes two spring shock absorbers along horizontal direction symmetry and slope setting.

According to the floor pipeline damping device, a pipeline penetrates through a hole of a floor slab, a shell is arranged on one side of the hole of the floor slab, a bottom pad is plugged between the shell and the floor slab, a pipe pad sleeved outside the pipeline penetrates through the shell, the bottom pad and the floor slab, two ends of the pipe pad are fixed through fastening assemblies, the shell and the bottom pad are fixed on the floor slab through fixing assemblies, spring groups for damping and buffering are arranged between the shell and the pipeline, and each spring group comprises at least two spring dampers which are arranged upwards and downwards in a tilting mode respectively. When vibration occurs, the spring shock absorber deforms to absorb energy and convert to apply shock absorption and buffering, and the deformation and the vibration direction of the spring shock absorber incline so that the spring shock absorber can be decomposed into two irregular vibration forces in the vertical direction and the horizontal direction; the vibration force in the horizontal direction can be absorbed by the spring shock absorber and the shell, and because the shell is arranged outside the opening of the floor slab instead of in the opening, except that the opening cannot be impacted, most of the vibration force cannot influence the floor slab, and only the rest of the vibration force can be converted into horizontal friction force to be transmitted to the floor slab, so that the influence on the floor slab is very limited; in addition, as for the vibration of the house, the vibration of the house in the horizontal direction is higher than that of the house in the vertical direction, so the vibration force in the vertical direction is small, and the floor slab cannot be damaged after the vibration is absorbed and buffered by the bottom cushion. Through this floor pipeline damping device, can effectively guarantee the buffering to the pipeline, keep the stability and the safety of pipeline, and the shaking force of its production can not direct action on floor and entrance to a cave, can avoid causing the secondary to destroy or cause harmful effects to the floor to the entrance to a cave.

In the floor pipeline damping device, the shell 2 comprises two shell pieces 21 which are oppositely arranged and form a ring, and the opposite ends of the two shell pieces are mutually connected through a locking assembly, so that the shell is convenient to mount or dismount, and the damping device is convenient to maintain. The locking assembly at one of the opposite ends of the two housing pieces 21 may be a hinge or connecting pin 22 for hinging the opposite ends of the two housing pieces 21; and the locking assembly at the other opposite end can be a screw, a bolt and nut pair or a shell quick-release lock 23 for mutually fixing the two shell pieces 21, the ends of the two shell pieces are oppositely contacted to form a ring during installation, and then the two shell pieces are fixed through the locking assembly, so that the operation is simple and convenient, and the work is stable and safe. In addition, shell 2 is equipped with annular through groove in the side department of the floor dorsad, has in addition can cover the shield 24 that annular led to the groove to make things convenient for maintenance personal to open the shield and overhaul damping device's inside, also can avoid the dust to get into inside damping device and influence the normal work of spare part.
