Robbery vehicle

from Wikipedia, the free encyclopedia

A rob vehicle , also Berauber called, is a mobile work machine in mining underground for Bereißen the ridges is used.

General

In potash and rock salt mining as well as in ore mining, routes or chambers are often created at great heights. So that the cavity contours of these pit structures are preserved, they have to be reworked at regular intervals. Due to the great height, this work cannot usually be done manually, so joints and ridges are worked on with a robbery vehicle. Due to their height, these vehicles are used especially in mining and tunnel construction.

Construction and technical execution

Robbery vehicles consist of a carrier vehicle and the swiveling telescopic boom mounted on it. There are both wheel drive and crawler vehicles. Two different mining vehicles have been developed and constructed for the mining operation, which differ in the way the boom works. There are peeling and striking robbers. With the hammering robber, special hydraulic hammers are rigidly attached to the head of the boom, while the peeling robber has a cutting head attached to the head of the boom (similar to a roadheading machine ).

The carrier vehicles are equipped with powerful, air-cooled diesel engines approved for underground operation and are state-of-the-art for underground operation. Hydraulic cylinders and hoses are protected from damage by metal sheets. These vehicles are often equipped with a clearing blade so that a wheel-driven vehicle has a safe stand on the road during work.

technical equipment of a carrier vehicle with all-wheel drive:

  • hydrostatic drive
  • Axis blocking
  • hydrostatic steering
  • all wheel drive
  • Protection against hydraulic overload
  • Exhaust gas scrubbing
  • articulated carrier vehicle
  • Hydraulic multi-disc service brake built into the axles
  • Cable or radio remote control of all functions, except driving

The driver sits in the driver's cab far and safely away from the robbery site. The driver's cab is armored to protect the driver. In addition, there are deflectors in front of the driver's cab to guide peeled or torn-off looseners away from the driver's cab. There are protective grilles in front of the windows, which are designed so that the driver still has good visibility. The driver's seat in modern vehicles can be swiveled hydraulically through 90 °. In today's robbery vehicles with striking robbery, the hammer is operated using a foot switch or a joystick.

Working method

There are robbery vehicles that work statically in a certain way and replace them with careful approach, telescoping and pincer movements. However, this way of working, which is comparable to pecking robbery with a hydraulic hammer, is very time-consuming.

Modern robbery vehicles provide up to twenty-five times more robbery performance than these static robbery vehicles. They can be equipped with a plow-like, hydraulic sliding plate, through which the route is cleared during the forward robbery process. This increases the robbery performance and reduces the wear and tear on the machine.

The robbery arm can - depending on the robbery height - be set up at an angle of 35 ° to 40 °. The robbery tooth is pressed against the roof or the side teeth against the joint with a pressure of up to 100 kN. Then the loose rocks and the larger looseners are torn down in 1st gear. Particularly solid plates or solvers are processed more aggressively by repeating the process.
