Description

one

The invention relates to the field of lifting: transport and can be used for installation and maintenance (during operation of electrical communications, for example, trolls located in industrial buildings and open areas in the area of the crane girder, as well as can be applied in other areas industry to perform various types of work: plumbing | installation and maintenance of communications and is an improvement of the device according to aut. St. number 863506.

The purpose of the invention is to reduce labor costs.

FIG. 1 shows a lifting device for installation work, a general view; in fig. 2 is the same side view} in FIG. 3 shows section A-A in FIG. 1 (operating position of the support bracket in contact with the side surface of the crane beam), in FIG. 4 shows a section BB in FIG. 3

The lifting and transporting device comprises a frame 1 movable from the drive, mounted on rails 2 of crane girder 3 by means of horizontal running rollers 4 and 5 and vertical runners of rollers 6. Fixes the running frame in a specific place and gives it additional stability relative to the rail clamping mechanism 7, consisting The screw is made of right and left threads with screwed-on cheeks that cuts the rail head when clamping.

The frame 1 has a mechanism for its movement, consisting of an electric motor 8, a gearbox 9 and a horizontal drive 4 and a slave 5 rollers, as well as a load lifting mechanism consisting of an arrow 10 turning 120, and an electric hoist 11,

 A movable frame of 12 L-shaped form with a support bracket 13 mounted on its vertical part is mounted on the mobile from the drive of the PC1me 1.

The main part of the support bracket 13 is made in the form of a frame 14 with guides mounted on two supporting posts 15, mounted on the vertical part of the suspension frame 12 is L-shaped and provided with 203007

 iTbix with asterisks 16, installed with the help of axes 17 on the supporting racks 15. The main part of the support bracket is equipped with a regulating device that allows adjusting the installation of the support bracket in height and length (not shown). The movable part relative to the main part of the support bracket 13 is executed as a closed circuit 18, located in the guide frames 14 and tensioned onto the sprockets 16 with the possibility of moving around them. To each cargo link 19, installed

f5 on the chain 18 with the same pitch with the help of the axis 20, the roller 21 is attached, in contact with the guide frame 14. To the load link m 19 of the chain 18 there are fixed supporting

20 pillars 22 (at least six), each of which has two rollers 23 each in contact with the surface of the crane beam.

On a suspension frame 12 L-shaped

25, a movable working platform (cabin) 24 with a control panel (not shown) is installed. The hanging frame 12 is made with guides designed to move 30 NIN of the movable working platform 24 in a vertical plane with its height fixed with the aid of bolts 25.

The proposed device is used as follows.

Using a truck crane, the device is installed on the rail 2 of the crane girder 3, and on the ground the level of installation of the mobile working platform 24 is pre-adjusted. The installer moves to the mobile working platform 24. The truck-crane is released.

Electricity is connected to the control panel using a cable. The entire device moves to the Pestle of the work and is rigidly fixed by a clamping mechanism for the rail head 2 to give it additional stability. At the same time, with the help of fur} lifting cargo, namely, booms 10 and electric hoist 11, a lengthy load (trolls, channel bars, pipes, etc.) is delivered to the height, and a small load (brackets, angles, etc.) and the tool is located in a moving work site. After lifting the load 35

It is necessary to perform installation work, such as mounting trolls. The device is periodically moved along the crane beam 3 and the cargo is delivered during installation work by the installer from the control panel located in the working platform 24. When the device is moved along the rail of the crane crane, the rollers 23 located on the supporting posts 22 on the lateral surface of the crane girder, while the pillars 22, the chain 18 and the sprockets 16 remain stationary relative to the main part of the support bracket 13 and the working platform 24. In the process of moving the lift The o-transportable device contacts the side surface of the crane beam with several support posts 22 with rollers 23 (for example, 6 stands) evenly spaced along the entire length of the working platform, and therefore the stability of the working platform relative to the crane beam increases.

As soon as the first support leg 22 collides with Kakime

or an obstacle, such as a stiffening rib 26, moves chain 18, which, together with supporting struts 5 22 located on it, moves relative to the main part of the support bracket 13 around sprockets 16 along frame guides 14. Movement of chain 18 relative to sprockets 16 The 10-ka post, having encountered an obstacle, will not come out of contact with it (stiffener 26) and the lateral surface of the sub-beam. Subsequently, the movement of the lifting and transporting device takes place with fixed posts 22, rolling along the side surface of the beam with the help of rollers 23.

Thus, the lifting and transporting device of the proposed design allows one to step over obstacles without stopping and without the intervention of the installer in the process of moving it along the 25 crane girder.

When complete installation work is completed, the device is removed from the rail and transported to the next installation site.
