Abstract

FIELD: drilling equipment engineering.

SUBSTANCE: device has body with bar placed on it in lower portion of which fuel combustion chamber is placed for thermal effect on destroyed rock, working tool, bar rotating drive and striking means having a striker. Drive for rotating bar is made in form of pneumatic muscles, one ends of which are fixed along perimeter of striker, and other ends are fixed on body. Pints of connection of opposite ends of each pneumatic muscle are displaced in spaced relatively to each other, and striker is made spring-loaded relatively to the body.

EFFECT: simplified construction, lower material costs.

Description

The device for the destruction of hard rock is intended for drilling rock and frozen soils.

A device is known for destroying hard rocks, including a housing with a rod placed in it, in the lower part of which a fuel combustion chamber is installed for thermal impact on the material to be destroyed, a working tool, a rod rotation drive and a percussion mechanism having a hammer (see, for example, Certificate for Utility model RU No. 8050 of January 21, 1998).

A disadvantage of the known device is the complexity of the design and high consumption of materials.

The basis of the invention is the task of simplifying the design and reducing material consumption.

The problem is solved in that in a device for the destruction of hard rocks, including a housing with a rod placed in it, in the lower part of which a fuel combustion chamber is installed for thermal impact on the material to be destroyed, a working tool, a rod rotation drive and a percussion mechanism having a hammer, a drive rotation of the rod is made in the form of pneumomuscles, some ends of which are fixed around the perimeter of the drummer, and the other ends are fixed on the body, while the points of attachment of the opposite ends of each pneumomuscular are puppies in space relative to each other, and the hammer is spring-loaded relative to the body.

The drawing shows a General view of a device for the destruction of hard rocks.

A device for destroying hard rocks includes a housing 1, a rod 2 installed therein with working equipment 3, a drummer 4, a heel 5, which is fixedly mounted on the rod 2. The drummer 4 has a spring 6 mounted on top of it. Between the fifth 5 and the lower case cover 7 1 a ratchet mechanism (not shown) is installed. The drive of raising the striker 4 is made in the form of pneumomuscles 8, which are fixed at one end along the perimeter of the striker 4, and the other ends on the body 1, while being the drive for turning the rod 2. At the bottom of the rod 2, a combustion chamber 9 is installed.

The device operates as follows.

Compressed air is impulsively supplied to the pneumatic muscles 8 from the pneumatic distributor (not shown), which leads to the rise of the striker 4 up the rod 2 relative to the heel 5, while the rod 2 rotates at a certain angle together with the working body 3, since the attachment points of the opposite ends of each pneumatic muscle 8 are offset in space relative to each other. The spring 6, which is loaded with a hammer 4 relative to the housing 1, is compressed. After this, the compressed air is discharged from the pneumomuscles 8 and the hammer 4, by stretching the spring 6, strikes the heel 5. The working tool 3, due to the impact energy transferred to it, destroys the rock or other material.

The ratchet mechanism is necessary for fixing the rod 2 when striking the heel 5. Thus, the working body 3 is installed on the previously not destroyed surface of the material.

In the process of mechanical destruction of the material at the same time there is a thermal effect on the latter by known methods.

Claims (1)
