Abstract

The adjustable holder is for a laser, particularly as used in mining. A disc has a vertical spindle on which a flange slewing in the horizontal plane is mounted, also a rail with a horizontal axis tilting the slewing plane in relation to the disc. The flange (14) with two ring-type mounting (15) fits on the vertical spindle, and has an adjusting screw with spring, a pressure spring, a yoke with clamping screw and a seal, acting against the disc flange. A plate (4) with a drilling (7) accommodates a clamping bolt (9). The screw is fixed in an outer wall (2) and slides in an inner one (3), fixed to the rail (1) with an elastic cover (23).

Description

The invention relates to a base for attachment and pivoting. of the mine-laser in the horizontal and vertical plane.

Pro. The so far known bases and tripods of geodetic laser instruments served as a model solution for photographic tripods and tripods for theodolites. These constructions are adapted to work with cameras or binoculars of not very large size and weight. The mine laser, intended for transportation and working in the mine, must - have adequate mechanical strength, be stored in a spark-proof cabinet and is therefore a heavy equipment. Heavy equipment using known pedestals or mounted on load-bearing structures causes premature wear of their moving parts and deviations that reduce the measuring accuracy of the equipment. Moreover, the known pedestal solutions do not guarantee dust, waterproof and resistance to active substances.

Known solutions pedestals for heavy equipment, allow free sliding. movement in two mutually perpendicular planes, but they do not have a fine drive train and therefore cannot provide a fine adjustment of the laser. They are mainly intended for film cameras, but it is not suitable for work in harsh working conditions, especially the environment contaminated - coal dust.

2.

Another known solution - it has - ten. regulatory options and allows subtle. however, the direction setting, or - this solution -, is not suitable for work in - heavy - - mine - conditions. It consists of many exposed movable adjusting elements which wear quickly in mining working conditions. The design is designed to work in one place and is not suited for its complexity to constantly relocate to new workplaces. Attaching this device '- to a vertical wall or ceiling would require special costs.

Another known solution is intended for cameras, antennas and lasers, it allows adjustment of direction in two mutually perpendicular planes, but does not allow fine adjustment. The pedestal of the present invention guarantees a fixed center of gravity, but can only operate in a vertical position. In addition, the cooperation of the bearing roller with the sliding bore cannot ensure permanent cooperation with heavy equipment.

The object of the present invention is to develop a stable and durable base suitable for working with a heavy laser apparatus for determining the direction of coal mining and driving tunnels.

This object is achieved by the development of a laser pedestal for use in mines, with a disc and a vertical axis on which it is placed 207648 on a flange for pivoting in a horizontal plane, and a rail with a horizontal axis for inclination of the plane relative to the disc of the pedestal; The principle is that a flange with two ring holders is mounted on the vertical axis, in which the adjusting screw with the adjusting spring and the sleeve with the clamping screw are arranged, the compression spring and the sealing element abutting on the disc flange on which the hole bracket is arranged; a screw terminated with a threaded nut, the screw being slidably inserted into the outer wall and slidable into the inner wall, the outer wall and the inner wall being fixed to the rail by a flexible cover and a movable wall with a skirt, adjusting screw and spring between them is rotatably mounted on the water arable axis.

The base according to the invention allows a stable laser attachment, both on the side wall and on the corridor ceiling, and ensures coarse and fine positioning in two mutually perpendicular planes. Its high mechanical strength allows transportation and collaboration with heavy-duty laser housings housed in spark-proof cabinets designed to work in mines in a methane atmosphere. The base according to the invention has a long service life and maintains the set position.

The construction is adapted to the harsh working conditions and is particularly resistant to dust, moisture and active substances. When working with a laser, it significantly eases the alignment of corridors and the direction of coal mining without the time-consuming adjustment of traditional theodolites on tripods. It is also suitable for coal harvester guidance. All this leads to an increase in mining output and to a precise delimitation of seams.

1 is a longitudinal section of the pedestal in the plane vertical to the horizontal axis; FIG. 2 is a longitudinal section of the pedestal along the horizontal axis; FIG. 1 and 4 show a partial cross-sectional view of a fine slope of the pedestal.

The base consists of a rail 1 (Fig. 2) to which the outer wall 2 and the inner wall 3 are fixed, between which a movable wall 6 is fixed on the horizontal axis 5. In the bracket 4 and in the movable wall 6 there are openings 7, 8 A screw 12 and a vertical axis 13 are attached to the lower end of the bracket 4, on which a flange 14 with brackets 15, 16 is mounted. Inside the flange 14, a sleeve 17 with a tightening screw 20 is inserted. on which a compression spring 18 and a sealing element 19 are mounted, and on the other hand an adjusting spring 21 and a screw 22 for horizontal adjustment.

The device is protected by a flexible cover 23. The movable wall 6 is provided with a flange 25 with an adjusting screw 24 for vertical adjustment by a spring 26, between which a carrier 27 of the bracket 4 is arranged.

The pedestal is rotated horizontally by rotating the flange 14 on the vertical axis 13 and precisely adjusted by the adjusting screw 22 after the collar 17 is fastened with the clamping screw 20. The compression spring 18 acts on the sealing element 19 and closes the opening around the retention bolt 20. This is done by turning the bracket 4 on the horizontal axis 5. Fine rotation is achieved by an adjusting screw 24 passing through the skirt 25 and the springs 2B acting on the carrier connected to the bracket

4. The coarse adjustment is carried out by a tightening nut 11, after which the position is precisely adjusted by means of the adjusting screw 24.
