UA142265U - TENSIONING ASSEMBLY OF THE DRILLING MODULE OF THE DRILL MODULE - Google Patents

Abstract

The tension assembly of the feed mechanism of the drilling module includes a chain tensioner and a base on which is rigidly fixed at least one rack provided with a mounting assembly for the chain tensioner. The chain tensioner is made of prefabricated bracket and hinged two-arm lever. The bracket is fixed in the mounting unit, and the two-arm lever is made with the possibility of attachment to each arm of the corresponding branch of the chain.

Description

The useful model belongs to mining engineering, namely to drilling equipment.

From the state of the art, the tensioning unit of the feeding mechanism of the drilling module is known, taken as the closest analogue, which contains a chain tensioner and a base on which racks are fixed, each of which is equipped with a fastening unit for a chain tensioner. In the design of the closest analogue, the tension unit of the drilling module feed mechanism is made individually for each branch of the chain (11.

The disadvantage of this tension unit of the drilling module feed mechanism is that in the case of individual fastening of the tension chain branches, it is impossible to ensure the same tension force of both chain branches during operation, which, in turn, leads to frequent breaks of one of them.

The useful model is based on the task of ensuring the stable operation of the drilling equipment module for anchor fastening, minimizing the cases of breakage of any branch of the tension chain.

As a result of solving the task, a technical result will be obtained: ensuring uniform tension of both branches of the chain by self-regulation. Achieving the technical result will ensure the consumer properties of a useful model: increasing the operational reliability of the structure due to the reduction of breaks in the tension chain branches.

The task is solved in the tensioning unit of the feeding mechanism of the drilling module, which includes the tensioner (1) of the chain (2) and the base (3), on which at least one rack (4) is rigidly fixed, equipped with a fastening unit (5) for the tensioner (1) of the chain (2), according to the useful model, the tensioner (1) of the chain (2) is assembled from the bracket (6) and the two-armed lever (7) hinged to it, while the bracket (b) is fixed in the fastening unit (5) , and the two-armed lever (7) is made with the possibility of attaching to each arm the corresponding branch of the chain (2).

In addition, it is suggested: - on the base (3), rigidly fasten the second rack (4) and secure it with the fastening node (5) for the tensioner (1) of the chain (2), and additionally fix the bracket (6) in the fastening node (5) of the second racks (4).

Cause-and-effect relationship between the newly introduced essential features of the formula and the declared one

The technical result is explained as follows. Making the tensioner (1) assembled from the bracket (6) and the two-armed lever (7) hinged to it with the possibility of attaching to each arm the corresponding branch of the chain (2) ensures the possibility of swinging the two-armed lever (7) in the hinge. Depending on which of the branches of the chain there is more or less tension force, the corresponding arm of the lever turns in the hinge, thereby loosening that branch of the chain, while at the same time the other arm also turns in the hinge, but in the opposite direction, and tightens the other branch of the chain . Since the chain system of the feeding mechanism of the drilling module is closed, self-regulation of the tension of the chain branches takes place in this way and the declared technical result is achieved: ensuring uniform tension of both branches of the chain by self-regulation, which, in turn, provides consumer properties: increasing the operational reliability of the feeding mechanism of the drilling module, reduction of tension chain breaks.

The essence of the useful model is represented by the drawing, which shows the general view of the tension unit of the feeding mechanism of the drilling module. 1 - tensioner; 2 - chain;

Z - base; 4 - rack; 5 - fastening unit; 6 - bracket; 7 - two-armed lever; 8 - axis; 9 - locking bar; 10 - fastening element; 11 - wire.

Industrial suitability

Realization of the useful model shown on the chair. is not exceptional, but clearly demonstrates the possibility of achieving the stated technical result.

The tension unit of the drilling module feed mechanism consists of a tensioner (1), a chain (2) and a base on which at least one rack (4) is rigidly fixed, equipped with a fastening unit (5) of the tensioner (1). On the chair. the version of the tension assembly with two racks (4) is shown, as it is more reliable. According to the utility model, the tensioner (1) is assembled from a bracket (6) and a two-armed lever (7) hinged to it by an axis (8). A corresponding branch of the chain (2) is attached to each arm of the two-armed lever (7).

As an option, the fastening unit (5) of the tensioner (1) is represented by a bolted connection (positions are not indicated on the drawing), although there may be other fastening options. The axis (8) is kept from falling out by a locking bar (9), fixed by fasteners (10) and a wire (11).

During operation, when one of the branches of the chain (2) is excessively tensioned, this overload is transmitted to the double-armed lever (7), which, balancing around the axis of the hinge (8), transfers the tension change to the second branch of the chain (2). Due to the fact that the chain system of the feeding mechanism of the drilling module is closed, the tension of the chain branches (2) is equalized.

For a specialist, from the preliminary description of the tension unit of the feeding mechanism of the drilling module, some modifications emerge that fall into the protection area of the useful model formula.
