Embodiment Construction

[0019] In order to illustrate the technical solution of the present invention more clearly, the present invention will be further described below in conjunction with the accompanying drawings.

[0020] In order to achieve the above object, main technical solutions of the present invention are:

[0021] A simple sensor loading and unloading bracket is used for quick installation and disassembly of microseismic sensors, and mainly includes two parts: a twisted support structure and a long axis.

[0022] The twisted support structure includes a threaded shaft 2 with a hole, two sets of long connecting rod structures centered on a long screw 9 , two short connecting rods 4 , a rivet 5 and an unthreaded shaft 6 with a hole. Each set of long connecting rod structures includes two long connecting rods 3 connected by a short connecting rod 4. The short connecting rod 4 is provided with two through holes for installing rivets 5. It is used to connect the long connecting rod 3 and the ...

Abstract

The invention belongs to the field of a geotechnical engineering technique, and provides a simple sensor mounting-and-detaching bracket and a use method thereof. The bracket comprises two parts, namely a hinging structure and a long shaft. Two long connecting rods in each set of long-connecting-rod structures in the hinging structure are connected through a short connecting rod. The ends of the long-connecting-rod structures in two sets are connected through a hole-equipped threaded shaft, and the other ends are connected through a hole-equipped non-threaded shaft. Through changing a structural distance, the shape of the whole hinging structure is changed. One end of a long screw in the long shaft is connected with a nut, and the other end is connected with a fixing nut. The fixing nut isrotated in a clockwise direction, and the distance between the hole-equipped threaded shaft and the hole-equipped non-threaded shaft is reduced, and the hinging structure is expanded to two sides. Thefixing nut is rotated in an anticlockwise direction, the distance between the hole-equipped threaded shaft and the hole-equipped non-threaded shaft is increased, and the hinging structure reduces tothe central long-screw side. The simple sensor mounting-and-detaching bracket can be used for quick mounting and detachment of a slight-shock sensor. The simple sensor mounting-and-detaching bracket and the use method thereof have advantages of simple application, low cost, repeated use, effective sensor mounting efficiency improvement and effective loss reduction in construction.

Description

technical field [0001] The invention belongs to the technical field of rock engineering, and relates to a simple sensor loading and unloading bracket and a use method thereof, which are extremely convenient for temporary installation and disassembly of sensors of a microseismic monitoring system used in rock engineering, and can be used repeatedly. Background technique [0002] In rock engineering, dynamic disasters such as slope landslides, rock bursts, water inrush, and coal mine gas are often encountered, seriously affecting the safety of construction personnel and equipment, and greatly hindering the construction progress. Therefore, it is very necessary to take real-time dynamic disaster early warning measures. Microseismic monitoring technology has been widely used as a new rock fracture monitoring tool. At present, microseismic monitoring technology has been implemented in major projects such as hydropower station slopes, tunnels, and coal mines. Dynamic disasters suc...
