Description

Technology area

The utility model relates to mining engineering, namely, drilling equipment.

State of the art

From the prior art there is known a tension unit for a drilling module feed mechanism, taken as the closest analogue, containing a chain tensioner and a base on which stands are fixed, each of which is equipped with a fastening unit for the chain tensioner. In the construction of the closest analogue, the tension unit of the drilling module feed mechanism is applied individually for each branch of the chain. [one].

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 provide the same tension force for both chain branches during operation, which, in turn, leads to frequent breaks of one of them.

A task

The utility model is based on the following task: to ensure the stable operation of the drilling equipment module for anchoring, minimizing the cases of breaks in any branch of the tension chain.

As a result of solving the problem, a technical result will be obtained: ensuring uniform tension of both chain branches by self-regulation.

The achievement of the technical result will provide the consumer properties of the utility model: increasing the operational reliability of the structure by reducing the breaks of the tension chains.

Disclosure of a technical solution

In the known from the prior art the tension unit of the drilling module feed mechanism, including 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) chains (2), in accordance with the technical solution, it is proposed to make a chain tensioner (1) (2) composed of a bracket (6) and a two-armed lever (7) pivotally connected to it, while fixing the bracket (6) in the nodes fastenings (5), and the two-armed lever (7) is made with the possibility of attachment to each arm of the corresponding branch of the chain (2).

In addition, it is proposed:

- on the base (3), firmly fix the second post (4), and provide it with the attachment point (5) for the chain tensioner (1) (2), and additionally fix the bracket (6) in the attachment point (5) of the second post (4 ).

The causal relationship between the newly introduced essential features of the formula and the claimed technical result is explained as follows. The design of the tensioner (1) is composed of a bracket (6) and a two-armed lever (7) pivotally attached to it with the possibility of attachment to each arm of the corresponding chain branch (2), provides the possibility of swinging the two-armed lever (7) in the hinge. Depending on which of the chain branches there is more or less tension force, the corresponding lever arm pivots in the hinge, thereby weakening this chain branch, at the same time the other arm also pivots in the hinge, but in the opposite direction - pulls the other branch chains. Since the chain system of the feed mechanism of the drilling module is closed, thus self-regulation of the tension of the chain branches occurs and the claimed technical result is achieved: ensuring uniform tension of both chain branches by self-regulation, which, in turn, provides consumer properties: increasing the operational reliability of the feed mechanism of the drilling module , reduction of tension chain breaks.

Industrial applicability

The implementation of the technical solution shown in Fig. 1 is not exclusive, but demonstrates the possibility of achieving the claimed technical result.

The tension unit of the drilling module feed mechanism consists of a chain tensioner (1) (2) and a base (3), on which at least one rack (4) is rigidly fixed, equipped with a fastening unit (5) of the tensioner (1). FIG. 1 shows a version of the tensioning unit with two posts (4), as more reliable. In accordance with the technical solution, the tensioner (1) is made prefabricated from a bracket (6) and a two-arm lever (7) pivotally connected 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 (in Fig. 1, the positions are not indicated), although there may be other fastening options. The axle (8) is kept from falling out by a locking bar (9), fixed by fasteners (10) and a wire (11).

During operation, with excessive tension on one of the chain branches (2), this overload is transferred to the two-arm lever (7), which balancing around the hinge axis (8) transfers the tension change to the second chain branch (2). due to which there is an equalization of tension in the branches of the chain (2). Taking into account the fact that the chain system of the drilling module feed mechanism is closed, the tension of the chain branches is equalized (2).

For a specialist, from the previous description of the tension unit of the drilling module feed mechanism, some modifications follow, which fall within the scope of protection of the utility model formula.
