Description

LIFT FOR CONSTRUCTION AND INSTALLATION WORKS

The utility model relates to elevators for lifting loads and people, as well as for installation work at heights.

According to the current GGTN rules, it is forbidden to deliver goods to window openings and niches from a crane pomp, but in practice such a need often arises. To mechanize the cantilever supply of goods, we suggest using an automobile hydraulic lift equipped with a telescopic handle.

A well-known hoist for installation and construction works comprising a vertical telescopic stand, to which work platforms and a variable boom load boom are suspended on adjustable articulated levers 1. The hoist allows you to cantilever deliver unit loads to the aperture by installing a crane with a horizontal boom.

The proposed design has a large weight, according to the design of the articulated mast and working equipment, which reduces the useful lifting capacity and stability of the lift.

A hydraulic manipulator is known, equipped with a telescopic handle with a hook manufactured by BAKM 2, which allows to feed loads console.

But the design of the handle does not provide for the possibility of using it with other attachments. In addition, the process of loading unloading is complicated since the service area is outside the operator's visibility zone.

Known automobile hydraulic lift containing articulated boom equipment with a working platform.

But the working platform does not allow for the console supply of goods into the openings 3.

due to the installation of various additional equipment, as well as ensuring the supply of cargo to the window opening with a direct overview of the service area by the operator.

The problem is solved by achieving a technical result, which consists in mechanizing the supply of consolio goods and loading and unloading them without the participation of a slinger (with a fork), the possibility of replacing load gripping devices, as well as a direct overview of the operator’s service area, by making fuller use of the car lift during construction -installation work equipped with a telescopic handle.

The specified technical result is achieved by the fact that in the elevator for construction and installation works containing articulated boom equipment with a working platform, the feature is that the handle of the elevator is located in the hinge area of the working platform, and also telescopically slides and has the ability to change the angle of inclination. Management is carried out both from the working platform and from the control panel of the lift. The telescopic handle is also equipped with a movable link on which a removable attachment is fixed.

The causal relationship between the claimed technical result and the signs of the proposed technical solution are as follows:

It is the telescopic handle of the lift, equipped with a movable link, that gives a wide range of changes in working positions, which allows you to feed loads into window openings and niches. Placing the handle in the hinge area of the platform allows the operator to control the telescopic handle in the immediate area. The handle is equipped with interchangeable working equipment: forks, hook, winch, bucket, which allows to expand the range of technological capabilities of the car lift. A distinctive feature of the handle of the lift is that it is used as additional equipment and does not require revision of the serial

car lift constructions. The handle is mounted on the head in the hinge area of the working site or instead of it.

The utility model is illustrated by drawings, where in FIG. 1 shows a general view of the handle; FIG. 2 a handle equipped with a hook in the position of supplying cargo to the opening, in FIG. 3 handle equipped with a fork.

The lift contains a handle and articulated boom equipment. The elevator handle contains telescopic sections 1, a movable link 2 for fixing removable attachments 3. The handle is hung on the upper section 4 of the lift in the hinge area of the platform 5. The hydraulic cylinder 6 is designed to change the position of the handle relative to the upper section 4 of the lift. The hydraulic cylinder 7 is designed to change the position of the movable link 2.

The handle works as follows.

With hydraulic cylinder 7, the movable link 2 with attachments 3 is mounted parallel to the horizon to accommodate tare piece cargo and is maintained in a predetermined position as the load rises or is suspended (in the case of using a hook). After lifting to the height of the opening, the load is cantilevered by changing the position of the handle with a hydraulic cylinder 5 and telescoping sections of the handle 1, lowered to the floor (Fig. 2) or unloaded by tipping (Fig. 3).

The handle also allows you to expand the service area of the lift. It is possible to use the handle to expand the functional capabilities of the hydraulic lift through the use of interchangeable attachments: forks, bucket, grabs, winch.
