Embodiment 1

[0020] Such as figure 1 As shown, a layer displacement gauge of the present invention includes a box body 1, a steel wire rope 2, a rock grabbing hook 3, a rope winding drum 4 and a spring 5.

[0021] The box body 1 is in the shape of a cuboid, and a partition 39 is arranged inside the box body 1 , and the partition plate 39 divides the box body 1 into a left chamber 40 and a right chamber 41 . One end of the rope winding drum 4 is fixedly connected with a first installation shaft 6, and the other end of the rope winding drum 4 is fixedly installed with a second installation shaft 7. The axes of the first installation shaft 6 and the second installation shaft 7 coincide, Both the left side wall and the right side wall of 1 are provided with installation holes 22, the first installation shaft 6 is installed in the installation hole 22 on the left side wall of the box body 1 for rotation, and the second installation shaft 7 is installed for rotation in the box body 1 in the ins...

Embodiment 2

[0030] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the second installation shaft 7 is fixedly connected to the first installation shaft 6 through the fixing key 23 . The first installation shaft 6 is a hollow shaft, the second installation shaft 7 is inserted into the first installation shaft 6, and the first and second installation shafts 6, 7 are provided with corresponding second and third shaft keyways 60, 61. A fixed key 23 is installed in the second and third shaft keyways 60 and 61, and the fixed key 23 is located outside the box body 1. By installing the fixed key 23, the relative rotation of the first and second installation shafts 6 and 7 can be prevented. One end of the spring 5 is fixedly connected to the partition plate 39 of the box body 1 , and the other end of the spring 5 is fixedly connected to the second installation shaft 7 .

[0031] The separation layer displacement meter of the present invention is in use,...

Abstract

The invention relates to a measuring device used for measuring terrane separation layer displacement, and aims to provide a separation layer displacement meter which is simple in structure, low in cost and convenient to install. The separation layer displacement meter comprises a box body, a steel wire rope, a rock grabbing hook, a rope cylinder and a spring, wherein the rope cylinder is fixedly connected with a first installation shaft and a second installation shaft, one end of the steel wire rope is wound on the rope cylinder, the other end of the steel wire rope penetrates through a rope through hole formed in the box body to be fixedly connected to the rock grabbing hook, one end of the spring is fixedly connected to a side wall of the box body, the other end of the spring is fixedly connected to the rope cylinder, the second installation shaft is further fixedly provided with a first reading dial, the first reading dial is installed on the second installation shaft in a sleeved mode, an outer circumferential face of the first reading dial is provided with scales, and one end of the first installation shaft is located outside the box body. According to the arrangement of the spring, the separation layer displacement meter can be conveniently installed on a tunnel wall.

Description

technical field [0001] The invention relates to a device for measuring length by a mechanical method, in particular to a measuring device for measuring the displacement of rock layer separation. Background technique [0002] The delamination instrument is a special monitoring instrument for monitoring the movement of rock formations in roadways. It can respectively display the layer separation of the roadway rock formation within the length range of the bolt and outside the range of the bolt. Provide coal mine engineering technicians and inspectors with the scientific basis needed to determine the support strength of the roadway surrounding rock, understand the rationality and economy of the support parameters used, and adjust the roadway support parameters in time according to the deformation of the roadway surrounding rock. Prevent roadway collapse accidents and ensure safe production in coal mines. Chinese patent CN 201935655U discloses a simple abscission instrument, m...
