Description

The invention relates to the mining industry, in particular to blasting installations for underground coal mining.

A planing device is known, which is equipped with a smooth planer that moves along an inclined guide, immovably fixed with a scythe on the slaughter side of the remaining pond of the conveyor. The traction chain of the plow is placed in the channels of the bevel guide. (See the book "Operation of planing machines", M.P. Lobanov and others:

Technology, 1984, p. 21-23).

The disadvantage of the known installation is that the traction chain of the planer is located on the slaughter side of the conveyor, which interferes with its maintenance and repair. In addition, the plow rests with grippers on the inclined guide, which has a limited size in height, which is necessary for the effective loading of coal on the conveyor. Such limitation of the height of the bevel guide does not allow to increase the caliber of the traction chain of the planer, which is necessary to increase the reliability of the installation design, and to ensure a stable position of the planer in the vertical plane when working on layers of medium thickness.

The closest in terms of technical substance to the declared solution, adopted as a prototype, is a planing device, which includes a planer of a smooth type with a gantry, which rests with grippers on a beveled guide, immovably fixed with a scythe from the slaughter side on the remaining bed of the conveyor, and with the help of a gantry on a circular guide , installed immovably from the backfill side on the remaining conveyor bed, the traction chain of the planer, placed in the channels of the bevel guide and connected to the lower grip of the planer (See Review of information of the coal industry TsNIEEIIUgugillya "Technical level of planing installations in the mines of countries - members of the CEV", series "Coal mining by underground method". M., 1978, p. 14).

It is possible to use the well-known planer unit on layers of medium thickness, as it is equipped with an additional support in the form of a portal, unlike its counterpart, which ensures the stability of the planer in the vertical plane. However, the disadvantage of this installation is the placement of the traction chain on the slaughter side of the conveyor, which leads to significant downtime during maintenance and repair of the installation, which is associated with difficulties in determining the location of the thrust of the plow traction chain, which is located under the bevel of the guide, and access to. of this circuit, which requires the opening of the bevel guide, which. as a rule, it is filled with coal, as it is used to load the crushed coal onto the conveyor. At the same time, the safety of performing these works decreases, as they are performed from the side of the face, where coal and rock may spill out. In addition, with an increase in the caliber of the chain located on the face side, the height of the bevel guide increases, which leads to additional resistance when loading coal onto the conveyor. In case of uneven operation of the grippers on the body of the planer, jamming of the portal gripper on the round guide installed on the bulk side of the conveyor is possible.

All this has a negative impact on the operation of blasting plants on formations of medium capacity.

The invention is based on the task of creating an effective planer installation of increased reliability and safety of work in the cleaning face due to the implementation of a portal in the form of a support pusher, freely connected to the planer, and the location of the traction chain of the planer with a guide on the backfill side of the conveyor, which will prevent jamming of the planer with the portal on the guides installed on the conveyor and will increase the productivity of the installation.

The solution to the given problem is achieved by the fact that in the planer installation, which includes a planer of a smooth type with a body, a portal, a conveyor with grates, on which a bevel guide with a scythe, according to the invention, is immovably fixed from the slaughter side, the portal is made in the form of a support pusher, which rests on the upper shelves of the grates and is made with a protrusion freely connected to the groove of the body of the planer, and on the back side it is connected to the traction chain placed in the guide. immovably installed on the remains of the conveyor, and additionally equipped with a hinge connected to the body of the plow.

The proposed planer installation compared to the prototype provides the possibility of using a chain of a larger caliber, without increasing the height of the coal load on the conveyor, due to the location of the guide of the traction chain of the planer from the side of the pile, and also reduces the downtime associated with the repair and replacement of the traction chain of the planer and attachments. thereby increasing the coefficient of machine time Those coal mining operations.

In the proposed technical solution, characteristic features are not characteristics of entire parts of the whole object, which can themselves be whole and independent objects with their own functions, that is why they are not classified separately from other parts (features), but the set of features laid out in recognition part of the formula, was not found in known technical solutions, that is why the proposed solution meets the requirement of "inventive level".

The technical result of the invention is an increase in the efficiency, reliability, productivity and safety of work by performing a portal in the form of a support pusher with a hinge connected to the body of the planer, and installing the guide of the traction chain of the planer on the bulk side of the conveyor.

The execution of the portal in the form of a support pusher, which rests on the upper shelves of the grates, and its execution with a protrusion freely connected to the groove of the planer housing, ensures a free connection of the portal with the planer housing, which eliminates their mutual jamming, increases the reliability of the structure. And the installation of a planer chain guide with a chain from the backfill side allows you to increase its caliber and ensure safety and convenience during the maintenance and repair of the installation, which reduces its downtime in the cleaning face.

The entire set of essential features of the proposed solution ensures reliable and efficient operation of the planer due to the possibility of using a chain of a larger caliber, increasing the safety of work, ease of work when repairing attached equipment, the traction chain of the planer.

The sprue installation is explained by the drawings, where in fig. 1 - shows the cross-section of the planer unit with attached equipment; in fig. 2 - view along arrow A in fig. 1.

The planer unit consists of a smooth-type planer with a body 1, a scraper conveyor with grates 2, on which a beveled guide 3 with a screed 4 is immovably fixed on the bottom side. On the backfill side, a guide 5 of a traction chain 6, a planer 1 with a bracket 7 is immovably installed on the grates of the conveyor 2 , on which holes 8 are made for connecting the lever-hydraulic control and movement mechanism. The plow with the body 1 grippers 9 is installed on the inclined guide Z with the possibility of movement along it. The portal is made in the form of a support pusher 10, which rests on the upper shelves of the grates, one end of which is placed movably in the guide 5 of the traction chain and is connected to the traction chain 6.

The second end of the pusher 10 is freely installed with the help of a protrusion 11 with a recess 12 in the body of the planer 1. On the support pusher 10 from the side of the pile, a stop 13 is hingedly installed, which is connected to the body of the planer 1 by means of a hinge connection 14.

The lathe works like this.

After turning on the drive of the planer (not shown in the drawing), the traction chain 6, connected to the support pusher 10, moves along the grates of the conveyor 2, resting on its upper shelves with the help of the traction chain of the planer b. located in the guide of the traction chain of the plow 5.

The support pusher 10 pushes the planer with the body 1 with a protrusion 11 with the help of a recess 12 made in the body of the planer 1 along the inclined guide 3, which separates the coal from the face and loads it onto the conveyor 2. The support pusher 10 provides with the help of a stop 13 and a hinge 14 its free connection with the body of the planer 1. which excludes their mutual jamming and ensures stable position of the planer in the vertical plane. , 15? with 2 ----3. i po ro: iz --i - ki pk sh shky would be A- ny Ugo ch te p, -- ee SYO PIT) "I A - 500 CDN NYA syu y y u EE EV --i y in -i- e - no y dl g -y ep la y. y GP Ya t ; ich ' pi ra "M I
