Description

The useful model belongs to the measuring instrument and is intended for the diagnosis of the wear of the bed of the chain of the drive star of the scraper conveyor, including directly in the mine.

From the state of the art, it is known, taken as the closest analogue, an adjustable caliber-stopper containing a housing, an elastically deformable working element installed on it and a mechanism for its movement, which is made in the form of ring sectors fixed on the ends of the housing, while the mechanism for its movement is made in in the form of a rod with multi-directional threads at the ends, which have two sections with different thread pitch sizes, and bushings installed in pairs coaxially at each end of the rod, one of which in each pair interacts with the thread of a larger pitch and is intended to interact with the inner surface of the ring sectors, and the other - with a thread of a smaller pitch and strictly connected with the same sectors (11.

The disadvantage of the design of the closest analogue is its complexity, as well as the impossibility of using it to control special dimensions, for example, the wear of the chain bed of the drive star of the scraper conveyor.

The basis of the technical solution is the task: to create a special measuring tool for monitoring the wear of the bed of the chain of the drive star of the scraper conveyor with the possibility of carrying out measurements, including directly in the mine.

Solving this problem will allow to obtain a technical result, which consists in the creation of a specialized caliber (plug for monitoring the bed of the drive star chain of the scraper conveyor, convenient and easy to use, including directly in the mine. Achieving the stated technical result provides the technical solution with consumer properties : timely diagnosis of equipment condition, including directly in the mine, which reduces accident risks and loss of time for repairs.

In the already known state-of-the-art adjustable plug gauge, which includes a housing (1), with a working element installed on it, which is made in the form of sectors (2) and (3), symmetrically fixed to the opposite ones with respect to the longitudinal axis (X) of the gauge- plugs at the ends (4) and (5) of the housing (1) with the possibility of movement along this axis of at least one of the sectors, and a rod (6) installed in the housing, the axis (U) of which is located along the direction of movement of this sector, according to the technical solution proposed : body (1) with sectors (2) and (3) to be made detachable from two parts so that each

From the part was provided, respectively, with sector (2) or (3), while in one of them, the main part (1.1) of the housing (1), a rod (b) was fixed, with which the second, movable part (1.2) of the housing (1) will be associated with the possibility of its movement along the rod (b); parallel to the rod (b), insert an additional rod (7) fixed in the main part (1.1) of the housing (1) into the structure, with which the movable part (1.2) of the housing (1) will be connected with the possibility of its movement along it; at the same time, in the movable part (1.2) of the housing (1), install a latch (8) with the possibility of its fixation on an additional rod (7); and each of the sectors (2) and (3) of the working element should be made in the form of a c-shaped part of a link of a circular chain.

It is also suggested: connect the latch (8) with the movable part (1.2) of the housing (1) with a threaded connection; provide the movable part (1.2) of the case (1) with a graduated scale (9); disassemble the housing (1) into two parts in a vertical plane (M vertical).

The causal relationship between the newly introduced essential features of the useful model and the declared technical result is explained as follows. The design of the body (1) is detachable from two parts, in one of which, in the main part (1.1), the rod (6) and an additional rod (7) are fixed parallel to it, and the second, movable part (1.2) is connected to the rods with with the possibility of longitudinal movement along them, it is much easier than in the nearest analogue to set the required controlled size in the range from the size of the bed of the chain of the new drive star to the permissible size of the bed of the worn star by separating parts of the case (1) with sectors (2) and (3) . The removable housing (1) of the stopper gauge allows you to very simply and conveniently set the amount of separation of its parts (1.1) and (1.2) on two guide rods (b) and (7) by combining the end (7.1) of the additional rod (7) with the graduation of the scale (9), which is applied to the moving part (1.2) of the housing (1), and then fix the required amount of clearance (I) with a threaded fastener (8). Such setting of plug gauge to the desired size can be done directly in the mine without any additional measuring tools. The implementation of sectors (2) and (3) of the working element in the form of a c-shaped part of a link of a circular chain makes the gauge plug specialized for the possibility of monitoring the wear of the bed of the chain of the drive star of the scraper conveyor. Achieving the declared technical result, namely: the creation of a specialized stopper gauge for monitoring the wear of the bed of the drive star chain of the scraper conveyor, convenient and easy to use, provides the technical solution with consumer properties: timely diagnosis of the condition of the equipment, including directly in the mine, which reduces accident risks and loss of time for repairs.

The essence of the technical solution is represented by the drawings, where: in Fig. 1 shows the adjustable gauge plug assembly, top view; in Fig. 2 shows a vertical section A-A of fig. 1; in Fig. 3 shows the adjustable caliper-stopper in isometry in the separated state of the two parts of the case; in Fig. 4 shows the installation of an adjustable plug gauge in the bed of the drive star chain of the scraper conveyor to check the amount of wear. 1 - body; 111 - main part; 1.2 - moving part; 2 - sector;

C - sector; 4 - end; 5 - end; b - stem; 7 - additional rod; 7.1 - end; 8 - retainer; 9 - graduated scale.

Industrial suitability

The implementation of a technical solution is shown (Fig. 1, 2, 3, 4) using an example that is not the only possible one, but clearly demonstrates the possibility of achieving a technical result.

The adjustable stopper gauge consists of a body (1), made of two detachable parts separated by a vertical plane (Mvert): the main (1.1) and movable (1.2), to the ends (4) and (5) of each of which sectors are attached, respectively ( 2) and (3), which are the working elements of the plug gauge. As a simpler option, the division of the case into two parts in the example is made vertically

With the plane (M vertical) (Fig. 2), although the plane of the connector can be stepped, inclined, etc.

To solve the main task - the creation of a specialized measuring tool for monitoring the wear of the chain bed of the drive star of the scraper conveyor, sectors (2) and (3) of the working element are performed in the form of a c-shaped part of a link of a circular chain.

In the main part (1.1) of the body (1), a rod (6) and, parallel to it, an additional rod (7) with an axis (U) are fixed, and the movable part (1.2) of the body (1) is installed on the rods with the possibility of its longitudinal movement along them, while the sectors (2) and (3) attached to the parts of the body (1) thus have the ability to move along the longitudinal axis (X) of the plug gauge (Fig. 1). Such mobility of at least one of the parts of the housing (1) allows you to easily establish the required amount of separation (I) of sectors (2) and (3) of the working element (fig. 2, 3), which can be measured, for example, with a caliper. But for the convenience of using the cork gauge, without the use of additional measuring tools, a graduated scale (9) is applied to the moving part (1.2) of the housing (1), on which the position of the end (7.1) of the additional rod (7) is set (Fig. 3), which is very convenient in underground conditions.

To fix the position of the moving part (1.2) of the housing (1) with a graduated scale (9) in relation to the end (7.1) of the additional rod (7), a lock (8) is provided in the design.

The claimed device works as follows. First, set the necessary amount of separation (I) of sectors (2) and (3) of the working element, fixed on the ends of the removable parts of the housing (1), to "NO passage" by aligning the end (7.1) of the additional rod (7) with the mark on the graduated scale (9) to measure wear on one side "A" of the chain bed of the drive star. In the future, the amount of wear is measured at certain intervals (Fig. 4). After wear from the "A" side of the bed of the chain of the drive star and the passage of the plug gauge, the conveyor star is turned with the unworn side "B" of the bed in the direction of the load of the traction chain of the conveyor. After that, the necessary amount of separation (I) of sectors (2) and (3) of the working element is set to "NO passage" by aligning the end (7.1) of the additional rod (7) with another mark on the graduated scale (9) for measuring bilateral wear of the bed of the drive chain stars of the scraper conveyor. In the course of the conveyor, measurements are again made with a certain periodicity. After wear on the "B" side of the bed of the chain of the drive star and the passage of the gauge plug, the star of the scraper conveyor is replaced.

Also, the technology of measuring can be different, for example: with a certain periodicity, because a fully assembled gauge-plug is installed in the bed of the chain of the drive star of the scraper conveyor and parts of the housing (1) are removed until sectors (2) and (3) rest against the surface "A" and "B", fix the position of the moving part (1.2) with the graduation on the scale (9) relative to the end (7.1) of the additional rod (7) with the latch (8), which shows the level of wear of the bed of the chain of the drive star of the scraper conveyor.

Thus, the claimed plug gauge is a specialized measuring tool for monitoring the wear of the bed of the drive star chain of the scraper conveyor, which is convenient and easy to use, including directly in the mine. It can be easily made from modern materials, using modern technologies.
