DE7933459U1 - REMOVAL LIFTING DEVICE ON A BREAKING MACHINE - Google Patents

Description

Pa / Me1

The innovation relates to a lifting device, which is used to expand a through a route created by a demonstration machine in the area of the setting head Expansion parts, consisting of one on the helical thread of the machine working platform that can be moved in lengthways, on which the hydraulic actuatable lifting arm for the Aushauteiie is arranged «

Such lifting devices avoid the disadvantage of previously known expansion lifting devices, which were permanently mounted on the cantilever boom. These previously known devices had the disadvantage that each time with the consignor a 3aues move the tunneling machine in the longitudinal direction of the route and un * i ir had to be brought into the correct position. The expansion hoodί,! Direction, from who start with the innovation, avoids this disadvantage for an area limited by the travel stroke, because the machine is within this area can remain in the position required for the cutting process while the extension can be lifted in the right place up to the hanging wall can. Deviations of the tunneling machine from the longitudinal axis of the route are made by lateral pivoting of the cutting boom and pivoting of the lift table balanced at the front end of the lift arm.

However, it often happens that for some reason the expansion is temporary outside of the limited range specified above. In such cases, the procedure described at the beginning was previously time-consuming troublesome process of the tunneling machine in the longitudinal direction of the route is necessary, often because of the pile and the tunneling direction the still standing face was not possible far enough.

Assuming the present Heuerung is an object of the invention to improve the known lifting device so that a setting of the extensions is also possible outside the range limited by the moving stroke of the machine area to have to proceed without the machine in track longitudinal direction.

In order to solve the problem, it is proposed, according to the innovation, that between | Hubari.i and work platform a guide I running in the longitudinal direction of the route Intended for LiifKjsverschiebung of the lifting arm towards the platform \

is. This proposal enables the displacement range of the V

Increase the lifting arm beyond the previous wetness 2u by adding an additional %

borrowed shift between lift arm and platform is proposed. , F

According to another feature of the innovation, the guide consists of zv / ei on the | Working platform provided rails in which the appropriately trained f Bracket of the lift arm is displaceable. Such rails can for example .ξ

v / else be simple and robust U-profiles or I-profiles. ΐ

Another special feature of the innovation is that the \ Rails are provided with holes in which the appropriately marked \

formed counter-bored mounting of the lifting arm by means of the f

Bores pushable bolts can be fixed. This simple construction \

tion enables the displacement range of the lifting device f

by simply pushing the lifting bar forwards in the guides of the work platform, \

where the lifting arm is bolted to the work platform in the desired position \

will. By moving the work platform on the cutting arm as you know it %

This simple measure increases the displacement range by the |

each set dimension. · |

\ The Neueruna is based on the. Drawing described. It shows:

In Fig. 1, 1 denotes the hub, which at 2 is not articulated Bracket 3 is connected. The hydraulic cylinder is also on the bracket 3 4 articulated »with which the lifting arm 1 vcrschwenk + in a vertical plane can be. At the front end of the lifting arm 1, the lifting table holder 5 is also provided in an articulated manner, on which the extensions are placed. Hie working platform 6 is attached to the screw arm indicated at 7, it has the guides (I-profiles) designated by 10 and is with Rollers 9 can be moved lengthways with respect to the cutting arm. The roles 9 are while being guided in the rails 10; it is actuated by the hydraulic cylinder 11th

According to the innovation, the bracket 3 of the lifting arm 1 is also in the guides S (Fig. 2) can be moved lengthways. The rails 8 are provided with bores 12 through which bolts 13 (Fig. 2) can be inserted, which at the same time can v / ground through corresponding holes in the bracket 3 and so cause the fixing of the bracket 3 of the lifting arm 1.

By appropriate selection of the holes 12 in the rails 8, the Bracket 3, lifting arm 1 and hydraulic cylinder 4 existing lifting device opposite the rail 3 can be brought into different positions in which the desired longitudinal displacement of the lifting device is achieved.
