Embodiment Construction

[0013] See attached picture. The inner rod 6 is located in the tube hole of the outer tube 7, and there is an annular gap between the tube hole and the tube hole. The upper end of the inner pull rod 6 is connected with the plug 8 on the top of the outer pull tube 7, the lower end is connected with the scale 2 at the lower nozzle of the outer pull tube 7, and the upper end of the scale 2 is matched with the lower nozzle of the outer pull tube 7. catch. The lower pipe body of the outer tie rod 7 has an external thread, and the external threaded rod is screwed with a nut 4, which supports the tray 5 on the nut 4, and the tray 5 is sleeved on the external threaded rod with a larger gap at the same time.

[0014] Still refer to the accompanying drawings. In order to clearly display the displacement, a waterproof fluorescent layer can be pasted on the outer surface of the scale 2. The waterproof fluorescent layer is divided into three warning color circles of green, yellow and red...

Abstract

The present invention relates to a tubular roof delamination indicator which relates to a device used for automatically monitoring the roof rock displacement in mines such as a coal mine, and the like, belongs to the technical field of roof rock displacing devices and is used for overcoming the using disadvantage of the inconvenient installation of the prior roof displacement meter. The tubular roof delamination indicator consists of an external pull tube and an internal pull rod arranged in the external pull tube. The upper end of the internal pull rod is connected with a plug at the top of the external pull tube, and the lower end is connected with a staff gauge at the lower tube opening of the external pull tube. The lower tube body of the external pull tube is provided with external screw threads. An external thread rod is mounted with a nut. The nut is supported and connected with a salver which is mounted at the external screw thread rod. The tubular roof delamination indicator is a tubular structure, the installing procedure is the same as a support roof bolt in the mine, and a drill is not required to be excavated specially, thereby saving time for changing a drill rod and for drilling, ensuring that the installation is simple, convenient and fast and obviously improving the installation and construction efficiency; in addition, the tubular roof delamination indicator also has the advantages of simple structure, being convenient for processing parts and components, the low cost of a product and reliable and exact monitoring and being fit for being used the substitute product of the prior roof displacement meter.

Description

technical field [0001] The invention relates to a device for automatically monitoring the displacement of roof rock layers in mines such as coal mines, and belongs to the technical field of roof rock layer displacement devices. Background technique [0002] Roof strata displacement meter is a safety detection device installed in the mine roof to monitor the displacement of roof strata. The installation of the roof displacement gauge requires special drilling, and the technical requirements for installation are relatively high, which makes the installation time-consuming and labor-intensive. For this reason, it is necessary to develop and provide a roof displacement device that is easier and quicker to install. Contents of the invention [0003] The object of the present invention is to provide a tube-type roof separation indicator which is easy to install, so as to overcome the disadvantage of inconvenient installation of the existing roof displacement gauge. [0004] Th...
