Description

Technical Field

[0001] The utility model relates to the technical field of shaft wall deformation monitoring, in particular to a shaft wall deformation monitoring device, which is mainly used for testing whether the shaft wall has obvious deformation. Background Art

[0002] Vertical shafts are important construction projects in underground mining, deep tunnels, and some water conservancy and hydropower construction fields, and have important functions such as transporting personnel and materials, as well as ventilation and drainage. Therefore, the stability monitoring of the shaft wall is an important consideration for safe production.

[0003] Commonly used shaft wall deformation devices are mostly single-point or multi-point displacement meters. The installation of the displacement meter requires drilling on the surrounding rock of the shaft wall, and then installing the displacement meter in the borehole. The installation process is too cumbersome. After the shaft wall is poured, the displacement meter must be connected to the powered signal acquisition system, and the deformation of the shaft wall is judged by the deformation of the displacement meter read in the acquisition system. The installation process of the entire monitoring equipment is relatively complicated, and what is monitored is data variables, which is not intuitive enough. In addition, the entire monitoring system also requires external power supply. The sensor lines and power supply lines are concentrated on the shaft wall, which is easy to cause damage to the lines during construction.

[0004] In view of this, it is necessary to design an improved shaft wall deformation monitoring device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0025] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0026] See also Figures 1 to 3 As shown, the utility model provides a shaft wall deformation monitoring device for testing whether the shaft wall has obvious deformation. The shaft wall deformation monitoring device includes an infrared signal transmitting and receiving device 10 and two infrared signal reflecting devices 20. The infrared signal transmitting and receiving device 10 has a built-in battery and does not need to be powered by external wires, thereby avoiding the problem of complicated lines in the shaft and the wires being easily cut by construction. The infrared signal transmitting and receiving device 10 includes a mounting portion, a first support plate 12, a second support plate 13, an infrared signal transmitting probe 121 and a switch 122 arranged on the first support plate 12, and an infrared signal receiving device 131 arranged on the second support plate 13, one end of the first support plate 12 and the second support plate 13 are abutted against each other, and the other ends are respectively connected to the mounting portion. When in use, the infrared light sent by the infrared signal transmitting probe 121 is reflected by the two infrared signal reflecting devices 20 and falls on the center point of the infrared signal receiving device 131.

[0027] In this embodiment, the infrared signal transmitting and receiving device 10 and the two infrared signal reflecting devices 20 are arranged at the same level and are installed on the circular shaft wall (such as Figure 3 shown).

[0028] See also Figure 1 As shown, the mounting portion of the infrared signal transmitting and receiving device 10 includes a first curved plate 111 having a first mounting hole 113 and a flat plate 112 connected to the first curved plate 111, and the first support plate 12, the second support plate 13 and the flat plate 112 are connected to form a triangle. The length of the flat plate 112 is greater than the projection length of the first curved plate 111 on the flat plate 112. The infrared signal transmitting probe 121 and the switch 122 are both arranged on the wall surface of the first support plate 12 facing the outside of the triangle. The infrared signal receiving device 131 is arranged on the wall surface of the second support plate 13 facing the outside of the triangle. A cross mark with a midpoint is arranged on the infrared signal receiving device 131.

[0029] The first curved plate 111 is a hard iron sheet (or other alloy material) with a certain curvature, and the curvature can make the device better fit with the circular shaft wall and enhance the stability of the installation. The expansion screw passes through the first mounting hole 113 on the first curved plate 111 to directly fix the entire infrared signal transmitting and receiving device 10 on the surface of the shaft wall, and the installation process is simple.

[0030] In particular, the switch 122 is a knob switch, which also has the function of adjusting the direction of the infrared signal transmitting probe 121, that is, rotating the knob switch can control the infrared signal transmitting probe 121 to rotate in the same direction.

[0031] The infrared signal reflecting device 20 includes a second curved plate 21 having a second mounting hole 211 and a signal reflecting plate 22 connected to the second curved plate 21, and the signal reflecting plate 22 is a smooth signal reflecting plate. Accordingly, the expansion screw passes through the second mounting hole 211 on the second curved plate 21 to directly fix the infrared signal reflecting device 20 on the surface of the shaft wall.

[0032] The installation and working principle of the utility model shaft wall deformation monitoring device are described below:

[0033] During installation, a set of infrared signal transmitting and receiving devices 10 and two infrared signal reflecting devices 20 are fixed on the wall of a circular vertical shaft in an equilateral triangle spatial position relationship; then the knob switch is rotated to emit infrared light, and the direction of the infrared signal transmitting probe 121 is adjusted by rotating the knob switch so that the infrared light can fall on the center point of the cross mark of the infrared signal receiving device 131 after being reflected by the two signal reflecting plates 22, and the installation is completed.

[0034] During use, if the wall of the shaft deforms, the landing point of the infrared light will leave the center point of the crosshairs and fall to another position, which can be directly observed.

[0035] It should be noted that since multiple lifting cables will be hung in the shaft during the shaft construction process, the transmission line of infrared rays may be blocked. Accordingly, the cable blockage can be avoided by increasing the number of infrared signal reflecting devices. As long as the infrared rays sent by the infrared signal transmitting probe 121 can be reflected by the infrared signal reflecting device 20 and fall on the center point of the infrared signal receiving device 131, there is no limit on the specific number.

[0036] In summary, the utility model provides a shaft wall deformation monitoring device, including an infrared signal transmitting and receiving device 10 and at least two infrared signal reflecting devices 20, all of which can be directly fixed on the shaft wall by expansion screws, and the installation process is simple; when in use, in the initial state, the infrared light sent by the infrared signal transmitting probe 121 is reflected by the signal reflecting plate 22 and falls on the center point of the infrared signal receiving device 131; subsequently, if the shaft wall is deformed, the landing point of the infrared light will leave the initial center point and fall to another position, which can be directly observed by the naked eye, and the monitored deformation effect is more intuitive; and the infrared signal transmitting and receiving device 10 has a built-in battery, does not require an external power supply, and does not require a complicated signal transmission line, thereby avoiding cumbersome lines.

[0037] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
