Abstract
The utility model relates to an adjustable shock absorber of a lateral screw. The shock absorber is used for absorbing the shock of a bridge cable and 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 arranged by being combined oppositely up and down; a barrel-shaped structure is internally provided with a shock absorption block (4); the outer walls of the upper cover plate (2) and the lower cover plate (3) are provided with a plurality of adjusters (1); each adjuster (1) comprises a box body (10) that is fixed on the outer wall of the upper cover plate (2) or the lower cover plate (3); the top outer side edge and the bottom outer side edge of the box body (10) are respectively provided with a through hole; a screw (7) is inserted in the through hole and spirally provided with a nut pin shaft (14) that is connected with a sliding block (8); the sliding block (8) is arranged in the box body (10); and an adjusting block (9) is inserted in the box body (10). The adjustable shock absorber of the lateral screw 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 side direction 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 side direction 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 side direction 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 lateral 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 outside have a screw rod to be inserted in this through hole along respectively being provided with a through hole, and described screw rod bottom is fixed with a back-up ring, revolve on the described screw rod and be equipped with a nut bearing pin, described nut bearing pin is connected with a slide block, and described slide block is arranged in the box body, 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 the nut bearing pin and axially moves, and makes when the slide block that links to each other with the nut bearing pin moves upward, and regulating block outwards can be ejected; Equally, when nut bearing pin drive 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, not only simplified the structure of damper greatly, and in use, can regulate a plurality of adjusters very easily simultaneously, greatly facilitate and 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.
