Abstract

The utility model relates to a falling preventing device for a hanging basket of an elevator, comprising ear plates on a cross beam of a hanging basket, bearing shell seat frames, clamping mechanisms with inclined surfaces. Channel plates with inclined surfaces of the two mechanisms are fixed on a fixed plate, clamp chewing blocks of the two channel plates are correspondingly contained beside the side surfaces of a vertical rail for the hanging basket, the two blocks are hinged on gears through hinges and the connecting rods thereof, and the two gears are engaged with a double-face rack which is hinged and fixed on the shaft end face of a shifting shaft through a cardinal shaft and a bolt; the shaft is extended from a falling guide slot hole of the plate and is positioned at the upper end of the hole, the shaft is suspended and connected to the shaft by a compression spring, so that the entirety of the clamping mechanisms can be supported. When the shaft falls down along with the hanging basket, the gears and the connecting rods can be driven by the rack, so that the clamp chewing blocks on the channel plates with inclined surfaces can be moved up and clamped on the upright rail for the hanging basket, and accordingly, the effect of preventing falling and the effect of fixing can be realized.

Description

Gig hanging basket falling proof device

The utility model relates to the improvement of Architectural Equipment, specifically is a kind of gig hanging basket falling proof device, and it belongs to the vehicle for construction technical field.

The gig of construction machine in the prior art generally all is equipped with disconnected rope safety dropping prevent mechanism.These safety dropping prevent mechanisms are by the wedge formula of traction insurance steel cable control and the clamping mechanism of eccentric wheel type.This mechanism will utilize steel rope twice, and its conservative factor is just smaller, and draws insurance steel cable and need debug installation, and its debugging operations is difficulty quite, takes a lot of work, and is time-consuming; There is this steel rope to lose efficacy again because of being in strained condition for a long time and being exposed to outer very easily corrosion.Facts have proved that there is defective in above-mentioned safety dropping prevent mechanism, needs to be resolved hurrily.

The purpose of this utility model is that a kind of later-model gig hanging basket falling proof device will be provided.This device otherwise the traction insurance steel cable is saved in the restriction of being drawn insurance steel cable improves the block construction configuration, in case when realizing that hanging basket is weightless, can clamp the perpendicular rail of hanging basket synchronously, prevents that hanging basket from falling.It is simple that the structure of this device is wanted, and Installation and Debugging are convenient, and are durable in use.

Task of the present utility model is finished by following technical scheme, developed a kind of gig hanging basket falling proof device, it comprises: symmetry is installed in the otic placode on the hanging basket crossbeam two ends, is installed in the bearing shell mounting on the otic placode, and symmetry is installed in the other inclined-plane clamping mechanism in the perpendicular rail both sides of hanging basket.The inclined-plane frid of described two inclined-plane clamping mechanisms symmetry respectively is vertically fixed on the adapter plate, this plate and the folder that two these frid upper embedded grooves are slidingly installed are chewed by relative three sides that are included in the perpendicular rail of hanging basket of piece, two these pieces respectively by hinge and rod hinge connection thereof on the anodontia outer rim of the gear that has several sector faces, be engaged with two-sided tooth bar between two these gears, the upper end of this tooth bar is solid on the axial end of dial axis by hinge bolt hinge, what this axial end was stretched out this plate leads cylindrical void, and by the solid upper end of hinge bolt hinge at this tooth bar, this shaft extension is led in the cylindrical void this plate, and can slide up and down in this hole; When the hanging basket normal operation, this is in the upper end in this hole, and is connected on this axle by the extension of the compression spring in the spring block set that is installed on this plate, thereby is supporting whole clamping mechanism; This other end hinge is solid in the bearing shell of bearing shell mounting.

This gig hanging basket falling proof device, described two-sided tooth bar, it is a hollow rack, and the tooth bar that mates with engaging gear is set in this tooth bar bilateral symmetry; In the center cavity of this tooth bar recoil spring is housed, this spring is supported between hinge bolt and this bottom surface, tooth bar lower end; This tooth bar is during with its pivotally attached dial axis free-falling, except driving its ingear two gears rotate, also born the impulsive force of black box free-falling body by the recoil spring in it, chews piece and is clamped in securely on the perpendicular rail of hanging basket thereby constitute this folder.

This gig hanging basket falling proof device, described inclined-plane clamping mechanism, it is by the inclined-plane frid that has dovetail furrow and be slidingly fitted in folder in this groove and chew piece and form; Two these frids that wherein are " T " font are separately fixed on the adapter plate, two these frid extended lines can intersect with the perpendicular rail of hanging basket respectively, the ratio of right-angled triangle two square edges that constituted is: end square edge: the vertical arm of angle=1: 1.5--5, and promptly this folder is chewed the ratio of two square edges of piece and is: 1: 1.5--5; But this folder is chewed the inclined-plane teeth that the vertical arm of angle piece face of piece is provided with the perpendicular rail of clamping hanging basket.

This gig hanging basket falling proof device, described adapter plate, also can hinged installation two set of contact on its plate face leading sheave on the cylinder of the perpendicular rail both sides of hanging basket, two groups of these pulleys are hingedly mounted on the upper/lower terminal of this clamping mechanism respectively.

Advantage of the present utility model is: owing to designed be fixed with the inclined-plane clamping mechanism on adapter plate, this mechanism is by the inclined-plane frid that has dovetail furrow and be slidingly fitted in folder in this groove and chew piece and form.Two these pieces respectively by hinge and rod hinge connection thereof on the anodontia outer rim of the gear that has several sector faces, two these gears are engaged with two-sided tooth bar again, this tooth bar upper end is solid on the end face of dial axis by hinge bolt hinge again, this shaft extension goes out leads cylindrical void on this adapter plate, and solid by hinge bolt hinge in the upper end of this tooth bar, this axle can slide up and down in this cylindrical void.This axle supports and is in the upper end in this hole by the compression spring in the spring block set that is installed on this plate when the hanging basket normal operation, make the non-clipping state in whole anti-fall device place, and make the hanging basket normal operation.When hanging basket is weightless, dial axis and adapter plate and fixing whole anti-fall devices such as inclined-plane clamping mechanism thereof are free falling body state with hanging basket, under the tension force effect based on compression spring, dial axis glides in this cylindrical void, and then drive this tooth bar and move down and to drive inwardly (the hanging basket erect the rail both sides) rotation respectively of two this gears, being hinged on two connecting rods on two these outer gear rim respectively can promote two folders of sliding fit in dovetail furrow again respectively and chew piece and move up, thereby be clamped in the perpendicular rail both sides of hanging basket, make whole anti-fall device and hanging basket thereof be in arrested state.This device saves the traction insurance steel cable, the substitute is the compression spring in the spring block set with protective value that is installed on the adapter plate, and---gear and connecting rod link are hinged---folder is chewed under the combined action of piece again at tooth bar, can finish clamping action.
