Definitions

  • the invention relates to a lowering machine, in particular for use in the routes in underground mining, the level of which has to be lowered to normal level again due to convergence-related elevations, with a machine frame, a running gear and a cutting device which can be inserted into the level of the level with a conveyor, via which the loosened pile is conveyed behind the machine frame.
  • lowering machines In underground mining, lowering machines are used which lower a track base that has swollen up due to mining measures in neighboring seams or for other reasons to such an extent that the cross-section required for the funding, weather management and driving is available again. Sinking machines of this type are used both in temporarily closed lines and in those companies in which the mining operation or the conveyor operation continues.
  • the lower loaders must therefore be very flexible. The dimensions are to be kept small due to the cramped conditions, but sufficient forces have to be applied in the area of the track bottom to be lowered in order to safely loosen the rock.
  • Lower loaders are known from DE-GM 8230528, DE-GM 7509458 and DE-OA 28 13202, the blades of which are equipped with teeth, the blades being articulated on a cantilever arm and being able to be pivoted into the optimum position in each case.
  • the hydraulically movable extension arm is used to press the bucket into the track base.
  • it is known to activate either the entire blade by means of a hydraulic vibrator integrated in the extension arm or the entire blade edge by means of a plurality of pneumatic or hydraulic striking tools arranged close to one another on the blade base.
  • the cutting device consists of two oversized working and arranged on the same drive shaft scraping wheels, on the outer circumference of scraper or fangs are attached.
  • the digging or fang loosen the material, obviously lignite, take it with it when it rotates and transfer it to a first conveyor, which transfers it to an intermediate conveyor provided on the machine frame of the extraction device.
  • Disadvantages are the relatively wide design of the scraper wheels arranged on the boom and the low drive power that can be transmitted because the first conveyor and the scraper wheels must be supplied by the same drive.
  • Rock as it occurs when lowering, cannot be extracted with such a device without additional auxiliary units or separate loosening work.
  • the overall height of such a device is particularly disadvantageous.
  • a sinking machine that works in principle in a similar manner can be found in DE-OS 29 11 705. This is where a cutting roller, which is arranged at the head of a cutting arm and is equipped with fangs or the like, works at the same time for crushing and loosening the rock, as well as for its removal in the direction of the conveyor.
  • a similar sinking machine can also be found in DE-PS 21 60643, which works similarly to the aforementioned sinking machine and has the same disadvantages in that the cutting roller rotating about a horizontal axis can only be operated with a correspondingly complex extension arm, namely the absorb emerging forces. To make matters worse, caterpillar tracks are used in these known machines, which offer only a limited possibility of safely transmitting the forces to be absorbed.
  • the invention is based on the object of providing a lowering machine for the re-cutting of the route sole which is dimensioned significantly smaller both with regard to the cutting forces and also the necessary restoring forces for the cutting device.
  • the cutting device has vertically arranged, pivotable swivel rollers, which are held by means of support arms, are connected to the machine frame which also serves as an abutment, and are height-adjustable.
  • the support arms are rotatably displaced in the case of two pivoting rollers on the side parts of the machine frame and have a compact support arm displacement. This gives you the opportunity to start the cutting work in the area of the track joint without any problems and to work from there swiveling towards the center in order to take full advantage of the advantages described above.
  • the material to be conveyed is moved in the direction of the central conveyor. pushed and fed so that he can advantageously take up and remove the clearing material.
  • the support arm displacement in its compact design enables the necessary forces to be introduced via the swivel rollers and the support arm as well as the support arm locking into the machine frame.
  • the support arms are assigned to the machine frame and are height-adjustable. According to a further development, it is provided that the support arm displacement can be adjusted in height by means of hydraulic actuating cylinders, so that support arms which are of a much simpler design can be used, which themselves have no joints, but rather only require the support arm displacement with their actuating cylinders to adjust the height of the swivel rollers can.
  • the support arms pivot the swivel rollers from the track joint to the middle of the track. According to a development of the invention, this is done in that the support arms have integrated swivel cylinders which enable correspondingly easy swiveling, even when the necessary pressure is exerted on the swivel rollers.
  • a compact design which does not put a lot of strain on the entire design of the lowering machine, is that in which the swivel rollers are equipped with a drive motor integrated into the hollow shaft of the roller body. It has been found here that the integration of drive motors with a power of 100 KW is possible, via which the necessary forces can be applied without problems.
  • Such swivel rollers could theoretically be compared with the breaker rollers on the main drive, the aim of the present invention being to use existing components as far as possible with regard to the components. This means that proven components can be used that have been in use for a long time with the crusher rollers.
  • a stable lowering machine which can be moved according to the progress of the dismantling, but still has optimal standing properties, is the one in which the machine frame consists of a front base plate that accommodates the support arm displacement, and a rear abutment, which can be braced against the track shocks and via hydraulic stepping cylinders and are mutually displaceable via runners which act as a chassis.
  • the hydraulic screeching cylinders are shifted spherically and bends between the base plate and the abutment are easily accommodated without the hydraulic screeching cylinders being loaded.
  • the base plate can also be raised or lowered in a targeted manner, so that troughs and saddles can also be optimally lowered.
  • the appropriate walking and at the same time the application of the necessary pressure on the swivel rollers can be achieved in that the base plate and the abutment can be braced independently of each other against the track joints via claws and support cylinders.
  • the claws and the support cylinders enable the necessary forces to be applied without there being a risk that the route extension against which the claws are moved will lose stability.
  • the claws ensure that the forces are applied to several butt segments of the extension at the same time.
  • the hydraulic shock cylinders are shifted spherically and that bends between the base plate and the abutment are designed to permit.
  • the vertical direction of the base plate can now also be changed additionally, for which purpose it is provided that the base plate is equipped with a level control supported on the abutment. This means that the base plate can be adjusted in accordance with all necessary changes in direction, so that the lowering work is completely routine.
  • the base plate is composed of one, the conveyor receiving middle part, two, the claws receiving, side parts and intermediate adapter strips. Depending on the connection of the individual parts, loads and forces can thus be absorbed without the other part being influenced.
  • the loading of loosened piles is facilitated by a special design of the middle part or the base plate, it being provided that the base plate is equipped at the front edge with a shovel-shaped loading ramp with side loading aprons and loading strip. Because of this design, the pile remaining in the Schrämgasse is pushed at the back onto the front part of the base plate, the shovel-shaped design favoring this. In this way, the pile is forcibly fed to the conveyor during the further return operations, so that it is impossible for the pile to slide out of the work area. Loading aprons on the side also capture the pile near the joint and feed it to the conveyor via funnel-shaped mounting plates.
  • a part of the weight of the base plate (total weight approx. 18 to 201) is derived in that, according to the invention, the loading bar has a tip bearing. This ensures that the patient lies clean and counteracts the tendency of the base plate to climb up the pile. This effect can also be countered by level control.
  • the work of the level control is favored by the fact that the rear lower edge of the base plate is chamfered.
  • the base plate can thus be brought into the ascending position by means of the corresponding control cylinder, without there being an obstruction between the base plate and the abutment.
  • the abutment like the base plate, is braced against the impacts.
  • the abutment can perform this function particularly well if it is divided into the middle part, side parts and adapter strips and is equipped with a central support for the conveyor so that the is relative movements between conveyor and abutment receiving.
  • the centrally located support for the conveyor can easily accommodate the relative movements between the abutment and conveyor during the back and also allows in curves, bends and similar positions.
  • the conveyor is constructed according to the invention so that it consists of a rigid frame which is placed on the support of the abutment and is horizontally rotatably mounted on the front part of the base plate. In this way, he can lift from the base plate when driving through troughs or from the abutment when driving through saddles without his function being impaired.
  • the base plate and abutment are additionally connected to provide level control.
  • the level control is formed by level control cylinders which sit rigidly on rockers and, like these, are rotatably fastened to the base plate and are connected via a universal joint to push rods which are mounted in the abutment in the longitudinal direction of the track.
  • the abutment-side stop takes place via two push rods, as mentioned, which are displaceably guided in the abutment in the direction of the route and are gimbally connected to the rockers in the manner described.
  • the prone pressure of the loading ramp can be increased (avoidance of climbing, improvement of the clearing effect) or the base plate can be placed in the - then undercut - lying surface (descending Driving style). This increases the versatility of the new sinking machine.
  • the invention is characterized in particular by the fact that a countersink is created which can be used in a variety of ways and which is small in terms of dimensions because it skillfully absorbs the necessary restoring forces and applies the cutting forces through a simple and very expedient design.
  • the overall optimally dimensioned lowering machine can be used practically in sections of any cross-section, ie width, because the adapter strips make it possible to quickly and easily adjust the width of the lowering machine to the width of the section, the two swivel rollers ensuring that with optimal application of the necessary cutting forces, these are so skillfully introduced into the mountains that the individual components can nevertheless be kept small.
  • the individual parts are coordinated and designed in such a way that the necessary cutting performance is achieved with the smallest possible aggregates, but also the necessary restoring forces are either reduced so far or at least absorbed so well that they hinder operation and prevent one enable the cheapest possible design. It is also advantageous that, with high cutting capacities, care is taken to ensure that the pile is always removed safely and that, due to the design, it is possible to work either with a stationary swivel roller or even with only one swivel roller if the line width or the equipment of the line so requires .

Abstract

Pour creuser des galeries, en particulier dans des mines de houille en exploitation souterraine, on utilise une machine de fonçage (1) dont le dispositif de coupe (17) comprend deux rouleaux pivotants (19, 20) agencés verticalement, ces rouleaux (19, 20) étant maintenus par des bras porteurs (21), reliés au châssis de la machine (10) servant en même temps de contre-appui, et configurés de façon à pouvoir être réglés en hauteur. Les relevages (7) dus à la convergence sont coupés par les rouleaux pivotants (19, 20), à partir du front de galerie (6) vers le milieu de galerie, et sont transférés en même temps sur le transporteur (8) par les rouleaux pivotants (19, 20) en marche contraire. Par suite de sa configuration, cette machine de fonçage (1) offre, en ce qui concerne les forces de coupe, ainsi que les force de rappel requises pour le dispositif de coupe (17), l'avantage d'un faible dimensionnement.
