Background
The ground collapse refers to a dynamic geological phenomenon that surface rocks and soil bodies collapse downwards under the action of natural or artificial factors and collapse is formed on the ground. Generally, the ground collapse is accompanied with the generation of ground cracks, namely, the surface rock and the soil body are cracked under the action of natural or artificial factors, and the geological phenomenon of cracks with certain length and width is formed on the ground. When this phenomenon occurs in an area where human activities are present, it can become a geological disaster. In particular, in a coal mine goaf, ground fractures generally need to be monitored and observed regularly, and geological changes are further presumed according to the change degree of the fracture fractures. The existing data collection means is single, regular monitoring is usually carried out manually through a general tool, fixed point deviation is easy to occur in the monitoring mode, observation is inaccurate, and the process is complicated repeatedly.

The equipment is researched and developed by a front-line worker, is placed in a selected observation area through simple and ingenious arrangement, realizes the fixation of observation points, is accurate in monitoring data and optimizes the operation flow.
The equipment comprises a supporting shell, a limiting disc and a crack monitoring mechanism.
The supporting shell is a main body supporting piece of the device, the supporting shell is integrally in a cylindrical form, and the upper end and the lower end of the supporting shell are provided with symmetrically arranged slots.
Is positioned in the middle of the support and is integrally provided with a limit disc. The limiting plates are used for transversely crossing two sides of the ground seam and have a supporting effect on the whole equipment.
Be equipped with crack monitoring mechanism in the supporting shell, crack monitoring mechanism specifically sets up the form as follows: the crack monitoring mechanism is formed by hinging two measuring rods, the outer diameters of the two measuring rods are smaller than the width of a cutting seam on the supporting shell, the two measuring rods are the same in length, and the hinging position of the two measuring rods is located in the middle of the supporting shell and is also the middle position of the two rod bodies. That is to say, wear to be equipped with a axis body in the supporting shell, two measuring sticks hinge in the middle of on this axis body.
A spring is arranged between the two measuring rods at the bottom of the measuring rod to support the two measuring rods; the top of the two measuring rods is integrally provided with a measuring scale in an extending way, and the two measuring scales are arranged oppositely.
Furthermore, the bottom surface of the limiting disc is integrally provided with a positioning thorn at the edge position, so that the positioning thorn can be penetrated into the ground on one side of the ground crack when the limiting disc is used, the anchoring effect on equipment is achieved, and the equipment is prevented from deviating due to natural reasons.
Furthermore, the measuring scale is provided with scales, and the upper part of the supporting shell is integrally provided with a T-shaped scale. The relative position of the measuring scale and the T-shaped scale is observed, so that preliminary reading is convenient.
The utility model has the advantages that: the utility model discloses simple structure, convenient to use, low in cost and easy to maintain through simple structure, have solved among the prior art ground crack monitoring fixed point and have easily squinted, observe inaccurate, the numerous and diverse problem of flow. The method realizes the fixation of observation points, has accurate monitoring data, optimizes the operation flow and makes the fixed-point monitoring of the ground fissure more convenient.

Detailed Description
Referring to fig. 1 and 2, a ground crack fixed point monitoring devices that sinks, including support housing 3, spacing dish 4 and crack monitoring mechanism.
The supporting shell 3 is a main body supporting piece of the device, the whole supporting shell 3 is in a cylindrical form, and the upper end and the lower end of the supporting shell are provided with symmetrically arranged slots.
Is positioned in the middle of the support and is integrally provided with a limit disc 4. The limiting discs 4 are used for transversely spanning two sides of the ground seam and play a role in supporting the whole equipment.
A crack monitoring mechanism is arranged in the supporting shell 3, and the specific arrangement form of the crack monitoring mechanism is as follows: the crack monitoring mechanism is formed by hinging two measuring rods 7, the outer diameters of the two measuring rods 7 are smaller than the width of a slot on the supporting shell 3, the two measuring rods are the same in length, and the hinging position of the two measuring rods is located in the middle of the supporting shell 3 and is also the middle position of the two rod bodies. That is to say, a shaft body is inserted into the support housing 3, and the two measuring rods 7 are centrally hinged to the shaft body.
A spring 6 is arranged between the two measuring rods 7 at the bottom of the measuring rods 7 to open the two measuring rods 7; the top of the two measuring rods 7 is integrally provided with a measuring scale 1 in an extending way, and the two measuring scales 1 are oppositely arranged.
When the device is used, the device is inserted into a ground crack below a limiting disc 4 through the limiting of the limiting disc 4, two measuring rods 7 are propped open through springs 6, and due to the specific arrangement form of the device, the spacing distance between the bottom of the two measuring rods 7 and the top of the two measuring rods are equal, and the width of the measuring rods is measured by devices such as a measuring ruler and the like, namely the local width of the ground crack in real time; after the arrangement is finished, the regular monitoring of the ground fracture can be finished.
Furthermore, the bottom surface of the limiting disc 4 is integrally provided with a positioning thorn 5 at the edge position, and when the limiting disc is used, the positioning thorn 5 can be penetrated into the ground on one side of a ground crack to anchor equipment, so that the equipment is prevented from deviating due to natural reasons.
