SU1450754A3 - Arrangement for fastening upper portion of plough on its lower portion - Google Patents

Abstract

To connect a plough top part, in particular a plate-shaped tool carrier, to a plough bottom part (plough body), a clamp connection is provided according to the invention, with the use of clamp pieces (16) which engage by means of locking projections (21) in locking recesses (22) which are arranged at the outer surfaces of the plough top part (14) and the plough bottom part (1) on either side of the joint. In this arrangement, two clamp pieces (16) opposite one another are conveniently connected and tightened from both sides by means of a common screw bolt (15). The clamp connection enables the plough top part to be put onto the plough bottom part or to be lifted off the latter without the plough top part having to be lifted to a considerable degree in the process. <IMAGE>

Description

The invention relates to a device for fastening the upper part of a plow, in particular a lamellar tool carrier, onto the lower part of the plow using threaded fingers,

The aim of the invention is to reduce the laboriousness of repair work on the maintenance of the plow.

Figure 1 shows the plow, a view of the co | 0 side of the clearing slab in conjunction with an accretion device; on ig.2 - the same, horizontal projection; Fig. 3 shows the upper and lower parts of the plow, a vertical section; on 15 ig.4 - the fixing device, a vertical section.

A plow consists of a body 1, which is mounted on a plow guide (not shown), which can be mounted in a known way 20 on the side of the clearing face on a semi-permanent bottomhole conveyor. The housing 1 of the plow is equipped with tool holders. At its one end, it has two 25 folding tool holders 2 and 3 arranged one above the other, which are respectively equipped with the slotting tools 4 and 5 arranged one above another, which are mounted in a toolbox with a replaceable tool in a known manner. The folding tool post 2 can rotate around the vertical axis 6, the folding tool post 3 can rotate around the vertical axis 7 that is 35 opposite to the rear axle 35. At the other end of the plow body 1, there is a rotary segment equipped with a steaming reamer 8 and a folding tool 9 located above it, which is equipped Sawing atJM cutters 10 and mounted on the body of the plow can be rotated around the vertical axis 11 of the rotation. Equipped with a scalding cutter 8 -45, the portal segment moves known-. a method along an arc guide body of the plow in a vertical plane; it has a steaming cutter 12 and several slotting cutters located above it 50.

The type, location and construction of individual tool holders 2,3,8 and 9 are of secondary importance and therefore do not require further development, especially since numerous versions of the coal plow are known, with mining mining tools located on the re-mounted tool holders.

In the proposed plow, a plate-shaped upper part 14 of the plow is detachably fixed on the lower body of the pillar 1, which is located between the hinged tool holders 3 and 9. The fastening is carried out with the help of threaded pins 15 (the arrangement of which is shown with a line in Fig. 2) and hose clamp 16.

The plow body 1, which forms the lower part, has solid undercuts 18 at the points of its flat, flat surface 17, while the upper part 14 of the plow, on its flat bottom side facing the upper surface 17, has corresponding undercuts 20. When installing the upper part 14 The plow on the lower part of the body 1, the plow of the recess 20 cover the recess 18, and every time the recess 20 with the recess W form a through hole for the bolt for the threaded one. pins 15. Approximately rectangular in configuration, clamps 16 have two parallel locking protrusions 21 in the form of ribs, which can fit into slot-like locking recesses 22 pa opposite lateral surfaces of the bottom part of the pillar 1 and the upper part 14 of the plow; In addition, the clamps 16 have a hole 23 respectively for mounting the threaded pin 15.

The upper part on its lower side 19 has one or more short centering studs 24, which may enter the corresponding recesses 25 for the plugs of the lower part of the plow body 1. "

When mounting the plate top part 14 of the plow is installed. on top of the lower part of the plow body 1, with centering spikes 24 inserted into the recesses 25 and the upper part 14 of the plow is centered relative to the lower part of the plow body 1. Then, at the fixing points, the locking projections 21 of the clamps 16 are inserted into the locking grooves 22 and through the holes for the bolts 23 arranged in pairs against each other the clamps 16 and the holes for the bots formed by pairs of notches 18 and 20, threaded fingers 1 5 are inserted, after which nuts 26 are screwed onto the latter and tightened. Thanks to this, the clamps 16 are firmly fastened. By connecting the locking projections 21 of the clamps to the locking recesses 22 of both parts 1 and 14, they are connected. The short centering types 24 inserted into the recesses 25 formed by blind holes can perceive shear forces arising during the operation of the plow between the upper part 14 of the plow and the lower part of the casing 1 of the plow.

Clamps Ib on opposite locking protrusions 21: the outer surfaces are correspondingly grooved

27DL place the nut 26 or the head 28 of the threaded pin. Threaded alts 15 can also be arranged in the manner that their heads

28 are located in the recesses 27 of the clamps 16, located on the side of the clearing.

The assembly can be carried out in such a way that the threaded pins 15 are first inserted into the recesses 18, after which the upper part 14 of the plow is mounted on top of the lower part of the body 1 so that the undercuts of the underside 19 lie on the threaded fingers 15 and lower recesses 18. Clamps and 6 can be strung on threaded bolts 15 before or after installing the upper part 14 of the plow.

When removing, the nuts 26 of the threaded bolts 15 rf are removed; the clamps are tightened or removed from the threaded bolts 15, after which the upper part 14 of the plow can be removed to the side after being slightly lifted.

Located on the side of the clearing in the plow body, the locking recesses 22 are located at the base of the extracts 29 of the outer surfaces 30 and 31 of the lower part of the pillar body 1 and the upper part 14 of the plow, and these extracts 29 form in pairs a support seat for the clamp 16. Located on the plow from the side of the clearing intake, clamps 16 are covered and. protected inside formed by stretching 29 support nests. Located on the opposite side of the plow, i.e. on

From the side of the worked-out space, the clamps 16 can be located covered respectively in supporting sockets, which are formed by corresponding stretches on the surface of the lower hull frame I and the upper part 14 of the struga. The clamp connection is suitable for joining different constructional hours. tey struga. Presented on the drawing of the plate part 14 of the plow has a sliding vertical nap

5, 32 of FIGS. 1 and 2, which extends upwardly the corresponding slide rail 33 of the hull I of the plow. A plow nozzle equipped with mining tools, adjustable in height, can be inserted into the guide 32, 33 from above.

Collars 16 on opposite piles of plows overlap junction points 34 () between the top

5 14 pallets and the lower part of the plow body 1 and the upper part 14 of the plow are firmly held by clamps from lifting them on the lower part of the plow. The arrangement can also be carried out in such a way that, due to the interlocking of the locking projections 21 with the locking recesses 22, a jamming is achieved, in which the upper part 14 of the plow has its lower side 19

5 is strongly attracted to the upper surface 17 of the lower part of the hull I of the plow.
