Description

An attached lifting scaffolding upright hanging hoisting device

technical field

The utility model relates to a hoisting and hanging system for building construction equipment, in particular to an upright hanging hoisting device for an attached lifting scaffold.

Background technique

Attached lifting scaffolding is a kind of protective scaffolding for high-rise buildings that has emerged in recent years, referred to as climbing frame; most of the climbing and descending power equipment of attached lifting scaffolding use chain hoists, commonly known as electric hoists. There are generally three ways to use electric hoists. The first method is to manually carry the hoist. In this way, the climbing frame needs to be manually transported to the working layer for each layer of work. It is labor-consuming and time-consuming to climb or descend after installing and fixing the hoist each time; Two ways: Use conversion parts to install the gourd upside down. Although it is not necessary to manually carry the gourd, the chain is easily broken when the gourd is upside down, and it is not easy to cover the gourd body. The gourd body is easily polluted during concrete pouring or in rainy days; the third method The method adopts the combination of steel wire rope and movable pulley. Although this method does not require manual handling of the hoist, the horizontal scaffolding is cut off at the machine position, and the passage of the scaffolding at the lower part of the scaffold is not smooth and the seal is not tight.

The utility model relates to an attached hoisting device for a lifting scaffold.

The utility model is an attached hoisting device for lifting and lowering scaffolding, which comprises a first sprocket group, a second sprocket group, a third sprocket group, an electric hoist, a hanging seat attached to a wall, an adjusting flower basket bolt, and a spring device. The first sprocket set is fixed on the hanging point, and the second sprocket set is fixed on the wall hanging seat; the third sprocket set is connected with the wall hanging seat by adjusting the turnbuckle bolt and the spring device; The main hook of the electric hoist is fixedly hung on the truss of the lifting point, and the truss of the lifting point is set corresponding to the truss of the lower lifting point, and is fixed on the upper side of the guide rail of the frame body; the other end of the hoist chain is fixed on the third sprocket group The hanging seat attached to the wall is fixedly arranged on the upper part of the structure between the truss at the lifting point and the truss at the lower lifting point;

Further, the hook of the first sprocket set is connected to the hanging point, the second sprocket set is connected to the hanging seat attached to the wall, and the tail end of the chain is fixed on the second sprocket set;

Further, an adjustment turnbuckle bolt and a spring device are arranged between the hoisting point truss and the wall-attached hanging seat;

Further, the relative distance between the hoisting point truss and the lower hoisting point truss can be set according to the height of buildings with different storey heights.

The utility model is an attached lifting scaffold hanging hanging system, prefabricated in the factory, easy to install and dismantle, does not need to manually carry the hoist, facilitates the hoist to cover, prolongs the service life of the hoist, does not need to use a combination of steel wire rope and movable pulley, and does not disconnect the horizontal direction at the position of the guide rail. Scaffolding is conducive to the airtightness of the scaffolding and ensures the smooth passage of the scaffolding at the lower part of the scaffolding.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Figure 1 and Figure 3, it includes the hanging point truss 1, the hanging point 2, the first sprocket set 3, the second sprocket set 4, the wall hanging seat 5, the adjusting turnbuckle bolt 6, and the spring device 7 , the third chain wheel group 8, the electric hoist 9, and the hoisting point 10 and the hoisting point truss 11 in addition.

The hanging point truss 1 is set on the lower side of the frame guide rail; the lifting point truss 11 is set on the upper side of the frame body guide rail; the main hook 901 of the electric hoist 9 is hung on the lifting point truss 11; It is connected with the hanging point 2; the second sprocket set 4 is fixed on the wall hanging base 5, and the tail end of the chain is fixed on the second sprocket set 4; the third sprocket set 8 passes through the wall hanging base 5 Adjust the connection between the basket bolt 6 and the spring device 7; the hoist main hook 901 is fixedly hung on the hoisting point truss 11, and the hoisting point truss 11 is set corresponding to the lower hoisting point truss 1 and fixed on the upper side of the frame guide rail; the other end of the hoist chain It is fixed on the third sprocket group 8; the wall-attached hanging seat 5 is fixedly arranged on the upper part of the structure between the lifting point truss 11 and the lower lifting point truss 1;

As an optimization, an adjusting turnbuckle 6 and a spring device 7 are arranged between the hoisting point truss 11 and the wall-attached hanging seat 5 .

As an optimization, the relative distance between the hoisting point truss 11 and the lower hoisting point truss 1 can be set according to the height of buildings with different storey heights.

The front-hanging hoisting device is realized in this way: when the electric hoist 9 is started, the distance between the first sprocket set 3 and the second sprocket set 4 is shortened, and correspondingly, the elongation between the third sprocket set 8 and the electric hoist 9 is the same Drive the lifting scaffold to climb up.

After the lifting scaffold climbs into place, the wall-attached hanging seat 5 is installed on the next working floor, and the electric hoist 9 is reversed to reverse the chain, and the chain of the hoist is restored to the initial state to enter the next cycle.

During the circulation process of the hoisting system, the turnbuckle bolt 6 and the spring device 7 are tensioned, so that the hoist chain is in a pre-tightened state, eliminating the error of the included angle between the chains, which is beneficial to the reciprocating cycle of the hoist chain.

The above descriptions are only preferred embodiments of the utility model, and are not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
