Abstract
The utility model specifically provides a kind of top plate displacement monitor for having and monitoring roadway roof displacement situation.Anchor bar body, anchor rod pallet board, nut, high sensitivity spring, pressure sensor are monitored including roadway roof displacement.Anchor bar body is fixed on back by using the mode of end anchorage, particular pallet is fixed on back by way of individually fixing through anchor bar body exposed junction, another pallet is installed in anchor bar body end head and fixation simultaneously, make to leave certain spacing between two pallets, high sensitivity spring is installed between, and pressure sensor is fixed between top tray and spring, the sinking of top tray is driven by top plate, the rock deformation pressure for generation of sinking is reached into pressure sensor by high sensitivity spring, thus the sinking displacement of back is calculated.This apparatus structure is simple, it is easy to accomplish.
Description
Technical field
The utility model is related to a kind of displacement monitoring technology of back, is supervised for the displacement of coal mine tunnel top board
A kind of method surveyed.
Background technology
In the colliery digging production process, back is suddenly pressed, caused strata behaviors, roadway in the roof from
Layer, so that inducing safety in production of the impact accident to colliery brings huge potential safety hazard, to reduce coal mine roof plate accident
Occur, with greater need for the monitoring strengthened to back.
The content of the invention
The purpose of this utility model is exactly to set up a kind of roadway roof displacement monitoring device, realizes that roadway roof displacement sinks
The real-time monitoring of amount.
To achieve the above object, the utility model takes following technical scheme.
A kind of roadway roof displacement amount monitoring technology, device mainly includes roadway roof displacement and monitors anchor bar body, anchor pole support
Disk, nut, high sensitivity spring, pressure sensor.Described spring displacement pressure sensor includes going deep into back
The anchor bar body in deep, described anchor bar body front end carries out end anchorage, and the rear end of described anchor bar body is provided with two end pallets,
Described one of end pallet, being fixed on by anchor bar body separately through nut on the top plate in tunnel makes anchor bar body and support
Disk is fixed on the end head of anchor bar body, two described pallets by nut without constant connection, another described end pallet
Between install and fix a high sensitivity spring, between the pallet that described spring is connected with top plate install pressure sensing member
Part.
The roadway roof displacement monitoring technology that the utility model is used further is configured, will using pressure sensor
Deformation force suffered by highly sensitive spring is exported.
The technical scheme provided from the utility model, mining tunnel top plate displacement monitor, by by anchor bar body
Front end is anchored in the rock stratum of top plate deep, in the exposed junction of anchor bar body, is reinforced top special trays in top through anchor bar body
On slate layer, lower tray is fixed on anchor bar body end by nut, makes to leave 5cm distance between two pallets, and holding in the palm
High sensitivity spring is installed, while installing pressure sensor between top tray and spring between disk.By this device, work as top
Slate layer is subjected to displacement, and high sensitivity spring stress is indicated the stressing conditions of spring by pressure sensor, so as to calculate top
The displacement of plate.The present apparatus is simple in construction and is easily achieved.

The described upper end of anchor bar body 1 is goed deep into the rock stratum of back, carries out end anchorage.
Described upper tray 2, through anchor bar body 1 and can not be fixed on top plate with the contact of anchor bar body effectively.
Described high sensitivity spring 4 be connected with pressure sensor 3 and be fixed on upper tray 2 and lower tray 5 it
Between.
Described pressure sensor 3 is connected with pressure display unit 7, can show the high sensitivity bullet caused by crushing
The rock deformation pressure that spring deformation is produced.
Deep anchor pole head is anchored in the stable rock stratum in deep when the utility model is operated, when superficial part rock deformation is produced
During displacement can significantly compression spring, and then rock deformation pressure is transferred to pressure sensor and information is gathered, shown by pressure
The delivery spring rock deformation pressure of device 7.Pressure display unit 7 is attached into the two of tunnel to help to be easy to reading, record data at position.
The utility model is simple in construction, and the installment work of device just can be synchronously carried out when tunnel carries out driving supporting,
It is easily installed, it is easy to accomplish.By the pressure display unit of roadway's sides, it is easy to observe data.
More than embodiment be only the utility model preferably embodiment, but creation of the present utility model
This is not limited merely to, every any modification carried out within this creation principal, equivalent substitution are all contained in this creation
Within protection domain.
