Abstract
The utility model relates to a kind of damping device, and it comprises damping spring, is wrapped in the rubber of described damping spring; Described rubber is square structure; Also comprise the multiple transverse steel and multiple longitudinal steel bar that penetrate whole described rubber; Multiple described transverse steel and multiple described longitudinal steel bar arranged in a crossed manner.The beneficial effects of the utility model are: the utility model employing rubber spring cushions can effectively reduce even to eliminate jointly removes product to the jerk effect on ground, makes simple good endurance, is convenient to recycle.
Description
Technical field
The utility model relates to a kind of damping device.
Background technique
Directional demolition blasting vibrations are a kind of main harm that blast working causes, with the explosion hazard ratio such as slungshot, shock wave, dust comparatively, have the advantages that destruction is larger and coverage is wide.In directional demolition blasting construction, blast products vibrations usually produce enormous impact to ground under building, concussion of blasting impact usually cause burying in the soil body under building oil, all kinds of pre-buried structure of feed channel destruction serious, often detection and operating expenses waste are caused to other facilities, constructional difficulties is loaded down with trivial details, hinders the adverse effects such as regional economy development.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of damping device, solves the deficiencies in the prior art.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of damping device, and it comprises damping spring, is wrapped in the rubber of described damping spring; Described rubber is rectangle body structure; Also comprise level and penetrate multiple transverse steel of whole described rubber and multiple longitudinal steel bar; Multiple described transverse steel and multiple described longitudinal steel bar arranged in a crossed manner.
The beneficial effects of the utility model are: the utility model employing rubber spring cushions can effectively reduce even to eliminate jointly removes product to the jerk effect on ground, makes simple good endurance, is convenient to recycle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In accompanying drawing, the list of parts representated by each label is as follows:
1, horizontal Insert Nut, 2, transverse steel, 3, rubber, 4, longitudinal Insert Nut, 5, longitudinal steel bar, 6, damping spring.
Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
A kind of directional demolition blasting form of construction work, first it empty the ground impacting shock position before explosion, again the above damping device of at least one deck is set in described impact endurance test shock position, maximum spacing between described damping device is no more than 0.5m, after finally waiting demolition blasting product clear, described damping device is dragged away.
As shown in Figure 1, a kind of damping device, it comprises damping spring 6, is wrapped in the rubber 3 of described damping spring 6; Described rubber 3 is square structure; Also comprise the multiple transverse steels 2 and multiple longitudinal steel bar 5 that penetrate whole described rubber 3; Multiple described transverse steel 2 is arranged in a crossed manner with multiple described longitudinal steel bar 5.
Preferred: multiple described transverse steel 2 is equidistantly arranged.
Preferred: the two ends of multiple described transverse steel 2 are equipped with horizontal Insert Nut 1.
Preferred: multiple described longitudinal steel bar 5 is equidistantly arranged.
Preferred: the two ends of multiple described longitudinal steel bar 5 are equipped with longitudinal Insert Nut 4.
Damping device itself can not produce extra shake punching effect as other damping device, before construction, damping device is dragged to suitable position and puts well just passable, easy construction.Directional blasting demolishment product drops on rubber, act directly on damping spring, shake punching is pulled off a soft landing substantially, weakened greatly, damping spring passes to rubber and passes to ground again, and now active force obtains the weakening of rubber and damping spring, and a power is separated into face power by rubber, reduce shake punching effect further, can well damping and shock absorbing.
The existence of transverse steel and longitudinal steel bar, the whole damping device lateral deformation of horizontal restrain, allows distortion all concentrate in the vertical, more can subtract cushioning punch effect.The existence of the Insert Nut of termination, retrains transverse steel and longitudinal steel bar, auxiliary damping device effect.After demolition blasting product has been cleared up, damping device just can drag toward next job site after simply checking, can repetitive cycling utilize, and cheap, construction is simple.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
