Abstract

The utility model discloses an underwater float body facility anchor rope automatic adjusting device, which comprises a rotary base and a pulley, wherein one end of the rotary base is fixed on a float body facility via a first hinge axle and the other end is connected with the pulley via a second hinge axle; the first hinge axle is vertical to the second hinge axle. When in use, an underground anchor rope bypasses the pulley to anchor a float body facility, since the pulley and the rotary base, the rotary base and the float body facility all adopt the hinge axle structure vertical to each other, when the angle of the underground anchor rope changes vertically and horizontally, the automatic adjusting device can rotate vertically and horizontally, to adapt the change of three-dimensional angle of the underground anchor rope, to automatically adjust the bearing state on the anchor rope, and hold the anchor rope and the automatic adjusting device at normal and safe bearing state.

Description

Buoyancy aid facility anchor line automatic regulating apparatus in the water

Technical field

The utility model belongs to the anchor device of facility in the bridge construction water, is specifically related to buoyancy aid facility anchor line automatic regulating apparatus in a kind of water.

Background technology

The bridge deep water foundation generally must rely on main facilitieses such as open caisson, steel cofferdam, steel bushing case to construct, and sees Fig. 1, Fig. 2.In the foundation construction that buoyancy aid facility 2 is carried out in adopting water such as open caisson, steel cofferdam, self-floating steel bushing case,, anchor line 1 under water also must be set in its bottom below water surface except that these positions more than facility water surface are provided with anchoring stay cord 5 waterborne.Only in this way, could control the state of these facilities in water fully, guarantee its security and stability in water.

Anchor line 1 is drawn the water surface by steering structure under water 4 under water, so that on buoyancy aid facility 2 or the guiding ship 3 it is fixed in water, and can adjust, control it.For the under water steering structure 4 of anchor line on open caisson, steel cofferdam, steel bushing case under water, adopted fixed structure in the past.Because of the anchor body is thrown the uncertainty put the position, and buoyancy aid facility 2 positions will change in the water such as open caisson, steel cofferdam, steel bushing case, and then anchor line 1 this a part of three-dimensional viewpoin between turning point and anchor body also is uncertain under water.Like this, fixing steering structure can not adapt to the variation of anchor line three-dimensional viewpoin, makes the force-bearing situation of steering structure, anchor line uncontrollable, causes steering structure, the destruction of anchor line under improper stresses such as wearing and tearing, card folding easily.

The utility model content

The purpose of this utility model is to provide buoyancy aid facility anchor line automatic regulating apparatus in a kind of water, to solve in the water buoyancy aid facilities such as the open caisson in the foundation construction, steel cofferdam, steel bushing the case anchor line and the stressed safety problem of steering structure under water thereof under water.

The technical scheme that realizes the utility model purpose is: buoyancy aid facility anchor line automatic regulating apparatus comprises swivel base, pulley in the water, one end of described swivel base is fixed on the buoyancy aid facility by first hinge, its other end is connected with pulley by second hinge, and first hinge is vertical mutually with second hinge.

When this device uses, anchor line passes the anchoring of buoyancy aid facility from pulley under water, because between pulley and the swivel base, adopt orthogonal hinge structure between swivel base and the buoyancy aid facility, when the variation of vertical angle of the stressed generation of anchor line under water and level angle, device also can be done vertical and the horizontal direction rotation thereupon, thereby can adapt to the variation of anchor line three-dimensional viewpoin under water, automatically adjust the stress of anchor line, make anchor line and this device remain normal, safe stress.

The utility model is described in further detail below in conjunction with accompanying drawing.

Description of drawings

Fig. 1 is the schematic diagram of buoyancy aid facility anchoring in the water.

Fig. 2 is Fig. 1 vertical view.

Fig. 3 is a structural representation of the present utility model.

Fig. 4 be among Fig. 3 A-B-C to view.

The specific embodiment

See Fig. 3, Fig. 4, the utility model device is located at the bottom of buoyancy aid facilities such as open caisson, steel cofferdam, steel bushing case, comprise swivel base 7, pulley 6, one end of swivel base 7 is fixed on the semi girder 8 of buoyancy aid facility 2 bottoms by the horizontally disposed first hinge rotating shaft 9, and its other end is connected with pulley 6 by the vertically disposed second hinge snap ring latch 10.

Rotating shaft 9 and swivel base 7 can make this device rotate in vertical plane, can adapt to the variation of anchor line 1 vertical angle under water; Snap ring latch 10 and pulley 6 can make this device rotate in horizontal plane, can adapt to the variation of anchor line 1 level angle under water.

The coxopodite of facilities such as open caisson, steel cofferdam, steel bushing case is made on the coast, finishes the installation of steering structure under water on coxopodite in advance.Anchor line is arranged in the side of buoyancy aid facilities such as open caisson, steel cofferdam, steel bushing case under water, and it is decided the control point same more than the water surface and can be located on the buoyancy aid facility, also can be located on its guiding ship.Make under water that anchor line passes pulley, the anchor line two ends are all caused the coxopodite end face, and anchor line is played dish.Cheese is placed in the coxopodite end face, and makes it temporary fixed.Make water under the coxopodite, and with its transportation by driving to the foundation construction position.Cheese is temporarily relayed to guiding ship or other hulls.Splicing block spare on coxopodite, the splicing of carrying out facilities such as open caisson, steel cofferdam, steel bushing case connects height.Will be under water anchor line with after the anchor chain of anchor body is connected, cast the anchor body of anchor line under water.The end waterborne of anchor line under water is connected with hoist engine, tightens up anchor line under water by hoist engine, and regulate the degree of tightness state of anchor line under water, reach the location status of adjusting facility, keep facility stable purpose in water by hoist engine.Anchor line is under water being carried out in the adjustment process,, anchor line is being acted freely owing to rationally be provided with the steering structure under water of anchor line, smooth slippage in steering structure, and make in stressed being in a safe condition of anchor line, steering structure.
