Beneficial effect of the present invention:
1, the present invention adopts the scheme of suspension bracket and pipe clamp combination, under normal state, pipeline is played to normal constraint and fixation, in the time that pipe-line system is subject to impacting, the displacement of restriction pipeline, absorb vibration, there is good shock resistance effect, effectively reduce the amount of deformation of pipe-line system, and adopt lifting type suspension bracket, facilitate adjustable, be applicable to different heights pipeline use;
2, be connected with pipeline and adopt flexible gasket, there is good vibration damping and engage effect;
3, the sandwich clad steel of pipe clamp outside and inner shock resistance device further strengthen vibration damping and shock proof effect;
4, adopt the pipe clamp of docking, within the specific limits, can finely tune for the pipeline of different tube diameters, economic and practical.

Embodiment
For illustrating technological scheme of the present invention and technique effect, below in conjunction with drawings and the specific embodiments, the present invention is described further.
As shown in Figure 1 to Figure 3, a kind of adjustable shock resistance clamp device, comprises following composition member:
(1) pipe clamp 10;
Described pipe clamp 10 is made up of a pair of semicircular arc (comprise semicircle and not to the circular arc of semicircle) hoop sheet, and the two ends of described semicircular arc hoop sheet all extend outward the flap for docking.
The inwall of pipe clamp 10 is covered with one deck flexible material layer 3, and preferred material is rubber material or polyurethane material, and flexible material layer 3 adopts colloid to be bonded on pipe clamp 10 inwalls.For the pipeline of different-diameter specification, capable of regulating uses the flexible material layer of different-thickness.
The outer wall 11 of pipe clamp 10 is the sandwich clad steel of filled polyurethane material, and the cavity between pipe clamp inwall and outer wall 11 is evenly equipped with some shock resistance devices 2 along tube wall.
As shown in Figure 2, described shock resistance device 2 comprises semicircle steel body and upper and lower two bases that pair of openings is relative, the end of described semicircle steel body extends outward kink, the kink of circular arc steel body is inserted solid on upper bed-plate or lower bottom base, in described upper bed-plate and pipe clamp outer wall, the face of side contacts is convex globoidal, the face that lower bottom base contacts with pipe clamp inner wall outside is concave arc surface, shock resistance device 2 can be stablized and fix between pipe clamp 10 inner and outer walls.
Hoop sheet flap is provided with through hole, by bolt 4 and nut 5, the flap docking of two semicircular arc hoop sheet is fixed, between two semicircular arc hoop sheet flap, be also provided with the rubber sheet gasket 6 of some strings on described bolt 4, described bolt 4 adopts middle-carbon steel material, nut 5 can use stainless steel material, and the length of bolt 4 should leave certain surplus, be convenient to be applicable to the pipeline of different thicknesses.
(2) lifting suspension bracket 1;
Described suspension bracket 1 is arranged on pipe clamp 10 tops, is connected with pipe clamp 10.Described suspension bracket 1 comprises top board 9 and a pair of telescopic hanger lever, and described hanger lever is positioned at the below of top board 9, comprises fixing rod and motion bar two-part, and fixing rod is connected with top board 9, scalable, carries out lift adjustment with the pipeline for different heights.Motion bar top is connected to the bottom of fixing rod, and lower end is connected with the flap after pipe clamp docking.
