Technical Field

The utility model relates to a pipeline antidetonation technical field especially relates to a gallows is combatted earthquake to door type.

Background

In the installation of pipeline, need use a antidetonation gallows to fix it at the top of building, current gallows has following defect: the pipeline presss from both sides for split type structure, and the centre all adopts screw fixed connection, but the screw is in long-time use, because there is the vibration problem in pipeline itself, and the pipeline has very strong tensile effect to the screw when the vibration, and the time is longer will break the screw to make the pipeline drop, lose guard action.

SUMMERY OF THE UTILITY MODEL

For overcoming prior art's defect, the utility model provides a door type antidetonation gallows, its aim at solve the problem that is broken when using screw fixed pipe to press from both sides and leads to the pipeline to drop.

The technical scheme for solving the technical problem is as follows: door type antidetonation gallows, including the pipe clamp, the pipe clamp is split type structure, be equipped with the shock pad between pipe clamp and the pipeline, through a plurality of first spring coupling between pipe clamp and the shock pad, the pipe clamp both ends symmetry is provided with first jib and second jib, the pipe clamp is through gim peg fixed connection, the gim peg includes the casing, be the cavity in the casing, it is provided with the piston to slide in the cavity, be fixed with the outer pull rod of body department casing on the piston, the pull rod passes behind the pipe clamp and fixes through the nut, be equipped with the second spring of cup jointing on the pull rod in the cavity, the second spring promotes the piston to the direction of keeping away from the pipe clamp.

The utility model discloses simple structure is ingenious, and convenient to use replaces the screw for the gim peg comes fixed connection pipeline to press from both sides, reduces the atress of connecting piece, increase of service life reduces the maintenance cost, guarantees safe in utilizationly.

Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

From fig. 1 to 5, a portal antidetonation gallows, including pipe clamp 1, pipe clamp 1 is split type structure, be equipped with shock pad 2 between pipe clamp 1 and the pipeline, be connected through a plurality of first springs 3 between pipe clamp 1 and the shock pad 2, pipe clamp 1 both ends symmetry is provided with first jib 4 and second jib 5, pipe clamp 1 is through 6 fixed connection of gim peg, gim peg 6 includes casing 7, be the cavity in the casing 7, it is provided with piston 8 to slide in the cavity, be fixed with the outer pull rod 9 of body department casing 7 on the piston 8, pull rod 9 passes pipe clamp 1 back and fixes through the nut, be equipped with the second spring 10 of cup jointing on pull rod 9 in the cavity, second spring 10 promotes piston 8 to the direction of keeping away from pipe clamp 1.

The piston 8 is provided with a one-way valve 11 and an overflow hole 12, the piston 8 divides the cavity into an upper cavity 13 and a lower cavity 14, and the flow direction of the one-way valve 11 moves from the upper cavity 13 to the lower cavity 14.

The upper chamber 13 is filled with hydraulic oil, and the lower chamber 14 is filled with half of hydraulic oil and air.

The pull rod 9 and the shell 7 slide in a sealing way.

When the utility model is used, the utility model,

be full of hydraulic oil in epicoele 13, pack partial hydraulic oil in the lower chamber 14 to select suitable second spring 10, then pass pipe clamp 1 and shock pad 2 with the pull rod 9 of gim peg 6, use the nut to fasten it, make initial condition down reach the balance, at this moment, shock pad 2 presses around the pipeline, and pipe clamp 1 is fixed it, makes the pipeline by steady fixed.

When vibration is generated, the pipeline can generate displacement, the damping pad 2 is pressed, the first spring 3 firstly performs buffering to absorb energy in the vibration, and when the vibration is transmitted to the pipeline clamp 1, the first suspender 4 and the second suspender 5 perform damping absorption again.

The split type structure of pipe clamp 1 for can produce certain pulling force to pull rod 9 of pipe bolt when the vibration between the pipe clamp 1, will produce the gap between the pipe clamp 1, pull rod 9 pulling piston 8 moves up this moment, second spring 10 compresses, the volume of epicoele 13 reduces, pressure increases, hydraulic oil flows into cavity 14 down from check valve 11 from epicoele 13, play absorbing effect, after the vibration elimination, second spring 10 extension, 8 both sides atress of piston are unbalanced, promote piston 8 and move down, the volume of cavity 14 internal volume reduces down, pressure increases, hydraulic oil flows back into epicoele 13 from overflow hole 12, thereby keep balance, get back to initial condition.

In shock attenuation process, pull rod 9 atress can be followed and pulled out in the casing 7, and the power that receives no longer is the rigidity pulling force on the current screw, but cushions power, avoids rigidity impact pull rod 9, reduces the damage to pull rod 9, and extension pull rod 9's live time, first spring 3 and shock pad 2 can play certain buffering vibration's effect, reduce the impact force to pipe clamp 1 directness.

Compared with the prior art, the utility model, following beneficial effect has: the shock pad and the first spring buffer the direct impact force of the pipeline on the pipeline clamp, so that the damage of rigid impact on the pipeline clamp and the pipeline is avoided; the pipe clamp uses the gim peg fixed connection, converts the rigidity impact force into the compliance, reduces the damage to the pull rod, prolongs the life of pull rod.
