Abstract

The utility model discloses an elevator mounting cradle, composed of a frame which is composed of at least four posts and a plurality of crossbars and the cross-section of the frame is quadrilateral or polygonal. Both sides of the upper part of the frame is provided with a winding engine, and a hanging beam is above the winding engine, while a work steel cable and a safety steel cable is connected between the hanging beam and the winding engine. The middle part and the lower part of the frame are equipped respectively with an upper flat base and a lower flat base, and a climbing stair is arranged between the upper flat base and the lower flat base, while the upper end and the lower end of the climbing stair are connected respectively with the upper flat base and the lower flat base. The upper part of the frame is provided with a safety lock and the winding engine is provided with a pressure disk. The upper end of the safety steel cable is fixed on the hanging beam and the lower end is fixed on the upper end of the frame after penetrating the safety lock. The upper end of the work steel cable is also fixed on the hanging beam and the lower end is fixed on the bottom of the frame after penetrating the pressure disk of the winding engine. Using the elevator mounting cradle to mount the electrical lift, work efficiency can be raised and the safety of workers can be guaranteed. The device is applicable to make the workers stand in mounting the electrical lift and transport means of the electrical lift.

Description

Elevator Installation Basket

(1) technical field

The utility model relates to a kind of hanging device.Be specifically be used for when elevator is installed for personnel stand and transport the elevator member can lifting Elevator Installation Basket.

(2) background technology

At construction trade, mostly adopt the method that in elevator hoistways, scaffolds erecting to realize the installation of elevator at present.Though adopt scaffold can realize the installation of elevator, it is cumbersome to scaffold erecting, time-consuming more, work efficiency is not high.But also it is very dangerous.

(3) summary of the invention

The purpose of this utility model is to provide a kind of Elevator Installation Basket.Use this Elevator Installation Basket that elevator is installed, can increase work efficiency, guarantee staff's safety.

Above-mentioned purpose of the present utility model is realized by following technical scheme:

Elevator Installation Basket of the present utility model, be characterized in that it comprises that the cross-sectional plane of being made up of at least four columns and some stulls is quadrangle or polygonal framework, there is gig the framework upper both sides, and there is hanging beam its top, is connected to load cable and safe steel rope between hanging beam and gig.In the framework, upper and lower platform is arranged respectively at the bottom, between upper and lower platform cat ladder is arranged, the upper and lower end of cat ladder is connected with upper and lower platform respectively.Framework upper has safety lock, and platen is arranged on the gig.Safe steel rope upper end is fixed on the hanging beam, and its lower end is fixed on the framework upper end after passing safety lock.Load cable upper end paddy is fixed on the hanging beam, and the bottom that is fixed on framework behind the platen of gig is passed in its lower end.

Adopt such scheme, have the following advantages:

Because the cross-sectional plane that Elevator Installation Basket of the present utility model is made up of at least four columns and some stulls is quadrangle or polygonal framework, there is gig the framework upper both sides, there is hanging beam its top, is connected to load cable and safe steel rope between hanging beam and gig.In the framework, upper and lower platform is arranged respectively at the bottom, between upper and lower platform cat ladder is arranged, the upper and lower end of cat ladder is connected with upper and lower platform respectively.When elevator is installed, saved the trouble that scaffolds erecting, can shorten the engineering time, increase work efficiency.Because framework upper has safety lock, platen is arranged on the gig again, safety factor is higher, can guarantee workmen's safety.

(5) specific embodiment

As shown in Figure 1, Elevator Installation Basket of the present utility model contains 11 on 11, four columns of four columns upper and lower platform 9 and 12, is tetragonal framework thereby form a cross-sectional plane.Be provided with stull 1 around the framework that upper mounting plate 9 and lower platform are 12 and around the framework on the upper mounting plate 9, the two ends of each stull 1 all are fixed on the column 11 of corresponding position with fastener.Upper and lower platform 9 and 12 are provided with cat ladder 10, and the upper and lower end of this cat ladder is connected mutually with upper and lower platform 9 and 12 respectively.

On relative two side positions of framework a gig is installed respectively, there is hanging beam 4 its top.This hanging beam is crosswise fixed above the hoistway of elevator.Be connected with safe steel rope 3 by load cable 2 between hanging beam 4 and the gig.A safety lock 5 is respectively installed in the framework upper both sides, and the upper end of safe steel rope 3 is fixed on the hanging beam 4, and the top that is fixed on framework behind the safety lock 5 is passed in its lower end.

See Fig. 2,3,4,5, said gig is made up of braking motor 7, platen and transmission device thereof, and the output shaft of braking motor 7 matches with platen by transmission device.Load cable 2 upper ends also are fixed on the hanging beam 4, and the bottom that is fixed on framework behind the platen of gig is passed in its lower end.

Said braking motor 7 is vertical layout, and promptly its output shaft is a vertical layout and towards the below, its output shaft lower extending end is connected to worm screw 19, and worm screw 19 1 sides have worm gear 16, and this worm gear is meshed with worm screw 19.Worm-wheel shaft one end is fixed with big or small gear pair 17 and 18, and said platen is arranged on the outside of big or small gear pair 17 and 18.Platen wherein contains shell 8, and driving gear 14 and ring gear 13 are arranged in the shell 8, and main,

ring gear

14 and 13 are meshed.Large Gear Shaft During in the size gear pair 17 and 18 stretches in the shell 8 of platen and is fixed in the axis hole of driving gear 14.

Be processed with circumferential step 15 on the one side periphery of said driving gear 14 and ring gear 13, to be used to hold load cable 2.After load cable 2 lower ends enter shell 8 from platen top one side, successively between a side of driving gear 14, the active and passive gear and after the S-shaped trend of opposite side of ring gear 13 walks around, pull out and be fixed in the bottom of framework by means of the circumferential step 15 on master, the

ring gear

14 and 13 and baffle plate thereof at last from the shell 8 bottom opposite sides of platen.

During work, the master, the

ring gear

14 and 13 that are driven in the platen by braking motor 7 and transmission device thereof rotate.Tightly clamp on master,

ring gear

14 and 13 and by this master, ring gear because load cable 2 is S-type, and load cable 2 lower ends are fixed on the framework, main,

ring gear

14 and 13 is in case rotation just can make framework rising or decline.The effect of safety lock 5 then is when fault such as knotting or fracture occurring when load cable 2, can pin safe steel rope 3 immediately, can not fall to guarantee hanging basket, thereby avoid the generation of personal safety and device damage accident.

For the well enclosure of avoiding hanging basket and elevator collides, around the upper and lower end of framework, all be equipped with and crashproofly take turns 6.
