Abstract
The utility model relates to a screw-adjustable shock absorber, which is used for shock absorption of bridge cables. The shock absorber comprises adjusters (1), an upper cover plate (2) and a lower cover plate (3), wherein the upper cover plate (2) and the lower cover plate (3) are fastened in an up-and-down manner to form an integral tubular structure, a shock absorbing block (4) is arranged inside the tubular structure, the plurality of adjusters (1) are disposed on the outer walls of the upper cover plate (2) and the lower cover plate (3), each adjuster (1) includes a case body (10) fixed on the outer wall of the upper cover plate (2) or the lower cover plate (3), the top portion and the bottom portion of the case body (10) are respectively provided with a through hole, a screw (7) penetrates into the through hole, a spacer (11) is fixed at the bottom portion of the screw (7), a slider (8) is screwed on the screw (7), and an adjusting block (9) is inserted inside the case body (10). The screw-adjustable shock absorber has the advantages of simple structure, convenient adjustment and wide adjustment range.
Description
(1) technical field
The utility model relates to a kind of damper, and especially a kind of screw rod adjustable shock absorber is used for the damping to bridge cable.
(2) background technology
In the bridge cable industry, for preventing that cable from because of concussion causes damaging, generally adopting damper that cable is carried out bumper and absorbing shock, so that prolong cable application life.Simultaneously because in actual applications, cable can not be in desirable concentric with pre-pipe laying, thereby need damper to have certain adjustable range, a kind of damping device as patent 97219875 is announced has certain adjustable range, but in actual use, not only complex structure, regulate operation many, complexity is installed, and because its structural limitations, when cable and pre-pipe laying eccentric throw were big, this damper can't use because of its adjustable range restriction.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of simple in structure, easy to adjust and screw rod adjustable shock absorber that adjustable range is wide is provided.
The purpose of this utility model is achieved in that a kind of screw rod adjustable shock absorber, described damper includes adjuster, upper cover plate and lower cover, the involutory setting up and down of described upper cover plate and lower cover, form a complete tubular structure, be provided with snubber block in the described tubular structure, described snubber block is that a hollow structure and outer rim are circle, this snubber block outer rim closely contacts with the tubular structure inwall, described upper cover plate and lower cover outer wall are provided with some adjusters, described adjuster includes box body, described box body is fixed on described upper cover plate or the lower cover outer wall, described box body top and bottom respectively are provided with a through hole, there is a screw rod to be inserted in this through hole, described screw rod bottom is fixed with a back-up ring, revolves on the described screw rod to be equipped with a slide block, has a regulating block to be inserted in the box body, described slide block and regulating block are wedge structure, and the cooperation that contacts of the wedge face of slide block and regulating block.
Operating principle is:
Screw rod on the rotary actuator, screw rod drives slide block and axially moves, and when slide block moves upward, regulating block outwards can be ejected; When slide block moved downward, regulating block can fall back in the box body.
During use, the lower cover of in pre-pipe laying, packing into earlier, the adjuster of regulating on the lower cover makes regulating block outwards eject the inwall that compresses pre-pipe laying; The upper cover plate of packing into subsequently utilizes backboard and side shield channeling conduct and location on upper cover plate or the lower cover, and the adjuster of regulating equally then on the upper cover plate makes regulating block outwards eject the inwall that compresses pre-pipe laying; The adjuster that can regulate on upper cover plate and the lower cover is adjusted in the claimed range eccentric throw subsequently.
The beneficial effects of the utility model are:
The regulative mode that adopts screw rod to drive slide block is regulated, and has not only simplified the structure of damper greatly, and in use, can regulate a plurality of adjusters very easily simultaneously, greatly facilitates to install and use and improved precision;
Regulating block directly is inserted in the box body, in the time need regulating bigger eccentric throw, only needs to change larger sized regulating block and gets final product, and has also improved adjustable range in simple in structure greatly.
