Definitions

  • the present invention relates, in general, the so-called bolting machines, intended for the execution of underground work, in particular in mining operations.
  • This invention relates, more particularly, to a drilling and bolting head, also here more simply referred to as “bolting head”, intended to equip such a bolting machine, the bolting head being of very compact structure, and adapted for use in low-rise mine galleries, this head being mounted on a carrier vehicle itself of low height.
  • a bolting head like that of the document EP 0 034 134 , is an assembly supported by a carrier vehicle and allowing to mechanically install retaining bolts in the roof of a mine gallery.
  • a bolting head is mounted at the end of a support arm of changeable length.
  • the assembly thus formed by the bolting head and its support arm is bulky and does not allow use in low pit galleries; in this regard, one must consider not only the bulk of the bolting head and its support arm, but also the large amplitude that results for the feeding movements of the bolting head in each desired working position , and the movements of passage of this bolting head from one position to another.
  • the present invention aims to avoid these drawbacks, by providing a drill head and bolting structure very compact, suitable for use and transport in mine galleries of low height and in other conditions where the available space is limited , thanks to a reduction in size, both in height and laterally and in advance, while maintaining handling qualities and ease of use, as well as good stabilization in working position.
  • the bolting head object of the invention has an orientable portion about a vertical axis, which is arranged a jack which plays the dual role of "advance block" for the slide, and stanchion to support the roof of the gallery, this principle of construction allowing a particularly compact realization and integrating all the necessary functions.
  • the intermediate support is mounted and guided in translation on a table disposed transversely, and provided with means for connecting it to one end of the carrier vehicle, motorized means being provided for control the movement of the slider along the table.
  • the means, provided for connecting the table with one end of the carrier vehicle, are preferably arranged to allow the lifting and lowering of this table.
  • These connecting means may comprise, on the one hand, articulating yokes of the table, about horizontal axes, to bases fixed on the end of the carrier vehicle, and on the other hand, at least one jack mounted between the carrier vehicle and said table.
  • the means for controlling the movement of the slider along the table may comprise a motor carried by said table, and an endless chain transmission connecting the motor to the slider.
  • the intermediate support is slidably mounted vertically on a front part of a telescopic support arm whose rear element is pivotally connected about a vertical axis with one end of the vehicle. carrier, motorized means being provided for controlling the pivoting of the support arm and the telescoping of the support arm.
  • This other embodiment retains, globally, a compact structure.
  • intermediate support may be pivotally mounted about a longitudinal axis, relative to the slide or relative to the front portion of the support arm, according to the embodiment, to "fold" the bolting head when is not in use, which reduces its height and facilitates the movement of the bolting machine equipped with this bolting head.
  • the slide is provided with vertical rear guides, slidably mounted in guide pads fitted to the vertical beam, and is also provided with anterior vertical guides, on which is mounted sliding the perforator.
  • the motorized means for controlling the displacement of the slide relative to the vertical beam, and the displacement of the perforator relative to the slide advantageously comprise a single motor, in particular carried by the vertical beam, which through at least one chain passing on return wheels controls the aforementioned displacements. A telescopic device is thus obtained, in which the total travel of the perforator results from the addition of the displacement of the slide relative to the beam, and the displacement of the perforator on the slide.
  • the bolting head further comprises means for pre-positioning, in a desired position or angular range, the orientable assembly constituted by the vertical beam, the slide and the punch, relative to the intermediate support.
  • These means may comprise, on the upper part of the intermediate support, a pre-positioning sector provided with a series of notches and articulated on the top of the vertical beam, a locking lever capable of being introduced into the notches in the pre-positioning sector.
  • said pre-positioning means comprise, on the intermediate support, a horizontal upper plate in which are formed, on the same circle centered on the vertical axis of rotation defined by said support, at least two successive lights in arc of circle, of angular extent corresponding to the amplitude of the rotation of the slide between the drilling position and the insertion position of a bolt, while on the aforementioned beam is mounted a vertical cylinder whose element mobile, directed upward, is able to be engaged in one of the choice of lights in an arc.
  • the ends of the arcuate lights are here the stops that define, for each selected work area, the two particular positions of the slide.
  • the perforator which is a compact perforator performing at each cycle of operation the drilling of a hole followed by the installation of a bolt, is advantageously mounted on a support, which also laterally carries a vertical housing, for the positioning and the introduction of a bolt, said housing and the drilling line of the drill being located on the same circle centered on the aforementioned vertical axis.
  • the invention thus provides a particularly compact bolting head, both in the vertical direction and in the front-to-back direction, particularly in the case where the usual support arm is replaced by a table providing a transverse movement and also lifting, while the vertical axis of advance to the block coincides with the pivot axis of the slide.
  • the telescopic slide adapting to the available height, fits vertically in the space of the machine, when it is retracted, which allows the machine to move between two successive positions of drilling and laying. a bolt, without having to fold the slide.
  • the bolting head design according to the invention eliminates a rotation movement usually required, which saves time and therefore provides a productivity gain.
  • the pre-positioning means of the slide, and the housing provided for the positioning and the introduction of a bolt make the bolting head of the invention manageable and easy to use.
  • all the motorized movements of translation and rotation of the bolting head are preferably radiocontrolled movements.
  • the figure 1 represents, as a whole, a bolting machine for mining operations, with a carrier vehicle 1 which, in the illustrated example, comprises a rigid monoblock frame 2 and four driving wheels 3, 4, that is two wheels 3 located on the right side of the chassis 2, and two other wheels 4 located on the left side of the frame 2.
