SU761718A1 - Method of lengthening filling-in pipeline - Google Patents

Description

The invention relates to the field of mining and can be used in underground mining of mineral deposits with the laying of the goaf.

There is a method of increasing the filling pipeline, which consists in connecting the expandable pipe to the end pipe of the pipeline using a quick coupling, [1].

The disadvantage of this method is that when building the pipeline, it is necessary to stop feeding the filling material, in addition, the high labor intensity of the connection of the pipeline.

There is also known a method of increasing the filling pipeline, which consists in connecting the expandable pipe with the main pipe of the final section of the pipeline with the help of a gripping chuck, ram and a fastening lock. In this case, the expandable pipe is attached to the lining section and, with its help, is supplied to the main pipe [2].

The disadvantages of this method are the impossibility of increasing the pipeline when feeding the filling material and the need for mechanisms for joining the stackable pipe with the main pipe.

The aim of the invention is to provide

increasing the filling pipeline without stopping the supply of filling material and improving the safety of work.

This is achieved by pre-harvesting the pipe 5 being expanded in the form of two half pipes with an inner diameter equal to the outer diameter of the main pipe, two half pipes are placed on the main pipe, fastened together and re-placed along the main pipe.

FIG. 1 shows the layout of the pipeline in the chamber; in fig. 2 is a structural diagram of the device with which the pipeline is expanded.

The pipeline consists of a main pipe 1 and a stack of stackable pipes 2, each of which consists of two half pipes 3. Half pipes are fastened to each other with 20 clamps 4, and stackable pipes - with locks 5. For movement of the stack of stackable pipes there is a feeding mechanism consisting of a gripping chuck 6 , to which the connecting link 7 kre25 rod with a piston 8 cylinder 9. The cylinder is in rigid connection with the tide 10 of the holder mounting mechanism

the supports 13 are rigidly fixed, equipped with skis 14, rounded at both ends.

In order to prevent people from entering the open mined-out space, the stackable pipes are moved along the array of the tab 15 on the supports 13. A double-end rounding is necessary for dismantling operations after the camera is fully laid. The rod mechanism moves to become detachable pipes assembled on the main pipe in the opposite direction and it is dismantled.

According to this method, the build-up of the filling pipeline is as follows.

The inner diameter of the two semi-tubes is pre-harvested (picked up), equal to the outer diameter of the main tube. Two half pipes are laid on the main pipe, fastened and moved by a feeder until the pipeline increases by approximately 2/3 of the half pipe length. In place of the extended pipe impose the next pair of half pipes, attach them to the first pair, and the process of movement is repeated.

This method of increasing the pipeline allows to increase labor productivity due to the continuous supply of material; reduce the amount of time-consuming work on the laying of the goaf by reducing the distance

pipe sockets, ease of assembly and disassembly of the pipeline, to ensure safety of labor when assembling the pipeline in the open mined space, since it eliminates the need for people to enter the mined space when building the pipeline.

Claims (1)

Claim ABOUT A method of increasing the filling pipeline, which consists in connecting a growing pipe to the main pipe using an exciting chuck of a cylinder and a fastening lock, which is characterized by the fact that, in order to ensure the building without stopping the filling material and increasing safety, the stackable pipe is pre-harvested in the form of two half pipes with an inner diameter equal to the outside diameter of the main pipe; two half pipes are placed on the main pipe, fastened together and moved along the main pipe.
