DETAILED DESCRIPTION

[0024] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0025] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0026] When predicting the danger of mine dynamic phenomena, it is necessary to install monitors in the mine to collect relevant data during excavation operations. When arranging the monitors, if the mounting bracket structure is unreasonable, it is not convenient to install the monitors at the work site. Therefore, if Figure 1 As shown, in the first aspect, an embodiment of the present application provides a mine dynamic phenomenon monitor mounting bracket 1, which includes a first frame 11, a second frame 12 and an adjusting rod 13. A first through hole is provided in the middle of the first frame 11, and more than two first connecting holes are provided along the circumference of the first through hole. The first frame 11 is configured so that after being sleeved on the monitor 2 through the first through hole, one side of the first frame 11 abuts against the monitor 2; the second frame 12 is provided with a second through hole, and the second frame 12 is also provided with a second connecting hole corresponding to each first connecting hole. The second frame 12 is configured so that after being sleeved on the monitor 2 through the second through hole, the relative position of the second frame 12 and the monitor 2 can be adjusted; each first connecting hole and the corresponding second connecting hole are provided with an adjusting rod 13, and the adjusting rod 13 is used to be penetrated through the first connecting hole and the corresponding second connecting hole to adjust the relative position of the monitor 2 and the second frame 12.

[0027] In this example, the mounting bracket 1 is designed as a split structure, specifically including a first frame 11 and a second frame 12, so that a storage space for the monitor 2 can be formed between the first frame 11 and the second frame 12. After the first frame 11 is sleeved on the monitor 2 through the first through-hole, one side of the first frame 11 abuts against the monitor 2, and the second frame 12 is sleeved on the monitor 2 through the second through-hole. The relative distance between the first frame 11 and the second frame 12 can be adjusted by adjusting the rod 13 according to the actual size of the monitor 2, so that the relative position between the second frame 12 and the monitor 2 can be adjusted. In this way, after the mounting bracket 1 is fixedly installed at the monitoring position of the mine dynamic phenomenon, the end of the monitor 2 close to the second frame 12 can be tightly abutted against the monitoring point to obtain a stable monitoring signal.

[0028] In addition, in this example, a plurality of first connecting holes are arranged on the first frame 11, and second connecting holes corresponding to the first connecting holes are arranged at corresponding positions of the second frame 12. The relative distance between the first frame 11 and the second frame 12 is adjusted by means of an adjusting rod 13 passing through the first connecting holes and the second connecting holes. This facilitates on-site adjustment operations, and at the same time, a contact force that meets monitoring requirements can be formed between the end of the monitor 2 and the monitoring point according to actual on-site conditions.

[0029] The mine dynamic phenomenon monitor mounting bracket 1 provided in the embodiment of the present application is provided with a first through hole in the middle of the first frame 11, and two or more first connection holes are provided along the circumference of the first through hole. The first frame 11 is configured so that after being sleeved on the monitor 2 through the first through hole, one side of the first frame 11 abuts against the monitor 2; the second frame 12 is provided with a second through hole, and a second connection hole corresponding to each first connection hole. The second frame 12 is configured so that after being sleeved on the monitor 2 through the second through hole, the relative position of the second frame 12 and the monitor 2 can be adjusted; each first connection hole and the corresponding second connection hole are provided with an adjustment rod 13, and the adjustment rod 13 is used to be inserted through the first connection hole and the corresponding second connection hole to adjust the relative position of the monitor 2 and the second frame 12. The mounting bracket 1 is easy to install at the mine operation site, thereby improving the convenience and flexibility of the on-site arrangement and use of the monitor 2.

[0030] In order to improve the ease of processing and installation of components, such as Figure 1 , Figure 2As shown, optionally, in one embodiment of the present application, the first frame 11 is a plate-like structure, and the edge of the plate-like structure of the first frame 11 is provided with more than two first lugs 1101, and each first lug 1101 is respectively provided with a first connection hole. The plate-like structure of the first frame 11 is convenient for providing the first perforation, and after the first perforation is sleeved on the monitor 2, one side of the plate-like structure abuts against the monitor 2, thereby forming an axial limit for the monitor 2. The first lug 1101 and the first connection hole provided on the first lug 1101 are provided at the edge of the plate-like structure of the first frame 11, so that when the adjustment rod 13 is inserted and adjusted, it will not affect the monitor 2.

[0031] In order to further improve the adaptability of the mounting bracket 1 to the on-site environment during installation, optionally, in one embodiment of the present application, the second frame 12 includes a limit member 121 and a fixing member 122, the second through-hole and the second connecting hole are provided on the limit member 121, the limit member 121 is connected to the fixing member 122, and the fixing member 122 is configured to be fixedly installed at the monitoring position of the mine dynamic phenomenon. In this example, the monitor 2 is specifically limited and fixed by the limit member 121, and the second frame 12 is fixedly installed at the monitoring position of the mine dynamic phenomenon by the fixing member 122, so that the first frame 11 connected to the second frame 12 and the monitor 2 are installed and fixed at the same time. The limit member 121 and the fixing member 122 of the second frame 12 can be adaptively designed according to the on-site environment. For example, the limit member 121 and the fixing member 122 can be designed as a simple plate-like structure, and the fixing member 122 can be installed and fixed at the monitoring position of the mine dynamic phenomenon. Figure 3 As shown, the anchor rod 3 and other structures at a preset distance from the excavation working face. As the excavation tunnel is continuously advanced, the installation position of the mounting bracket 1 can be moved forward accordingly, always maintaining a preset distance from the excavation working face.

[0032] Optionally, in one embodiment of the present application, the stopper 121 is a cylindrical structure with openings at both ends, the inner cavity of the cylindrical structure of the stopper 121 forms a second through hole, and a plurality of second lugs 1211 are provided on the cylindrical wall of the stopper 121, and each second lug 1211 is provided with a second connection hole. In this example, the stopper 121 is designed as a cylindrical structure, and the monitor 2 can be passed through the cylindrical structure, so as to facilitate radial limiting of the monitor 2; corresponding to the first lug 1101 on the first frame 11, the second lug 1211 on the cylindrical wall of the stopper 121 and the second connection hole provided also facilitate the adjustment operation of the adjustment rod 13.

[0033] When designing a radial limiting scheme for the monitor 2, optionally, in one embodiment of the present application, a stop hole 1212 and a stop member 1213 are further provided on the cylinder wall of the limit member 121, and the stop member 1213 is configured to be penetrated through the stop hole 1212 to abut against the monitor 2. After the monitor 2 is penetrated through the second through hole formed by the cylindrical structure of the limit member 121 of the second frame 12, the stop member 1213 penetrated through the stop hole 1212 of the cylinder wall can abut against the monitor 2, thereby forming a radial limit for the monitor 2. Specifically, a plurality of stop holes 1212 and stop members 1213 can be circumferentially provided on the cylinder wall of the limit member 121, the stop hole 1212 can be a threaded hole, and the stop member 1213 can be a screw.

[0034] In order to improve the adaptability of the mounting bracket 1 to the complex mining environment of the mine, such as the environment with severe coal seam crushing, optionally, in one embodiment of the present application, the fixing member 122 includes a first fixing end, a second fixing end, and an extension structure extending from the first fixing end to the second fixing end, the first fixing end is connected to the cylinder wall of the limiting member 121, and the second fixing end is provided with a mounting hole 1221. In this way, Figure 3 As shown, the limit member 121 can be connected to the first fixed end of the fixing member 122 according to a preset installation angle, and the second fixed end of the fixing member 122 can also be fixedly connected to the monitoring position of the mine dynamic phenomenon through the installation hole 1221 according to the actual situation on site. The extension structure of the fixing member 122 can adopt a suitable structural shape or material properties according to the on-site mining environment. For example, it can be designed as a special-shaped structure, or a material with elasticity can be selected to form an extension direction or extension path that meets on-site needs, so as to ensure that the first fixed end of the fixing member 122 provides a bearing function for the monitor 2 even in the complex operating environment of the mine, and the second fixed end of the fixing member 122 provides a fixed connection function with the monitoring position of the mine dynamic phenomenon.

[0035] When the mounting hole 1221 is used to fix the connection with the monitoring position of the mine dynamic phenomenon, optionally, in one embodiment of the present application, there are multiple mounting holes 1221, and at least one of the mounting holes 1221 is a waist-shaped hole. Multiple mounting holes 1221 can adopt different apertures to improve the connection adaptability with the existing structural components at the on-site monitoring position. In addition, when the mounting hole 1221 adopts a waist-shaped hole structure, the ability to correct position errors during on-site installation can be further improved, thereby improving installation efficiency.

[0036] Considering that in some working environments, such as when working on the mining face of a coal mine, the monitor 2 can be installed on the hydraulic support 4 of the mining equipment 20 meters to 30 meters away from the mining face, and the monitor 2 is automatically advanced along with the hydraulic support as the mining continues.

Specifically, as Figure 5 As shown, the connecting parts can be selected from bolts and nuts, by connecting the two ends of the arc-shaped structure of the first hoop body 1222 and the second hoop body 1223 to form a ring, and clamping the hydraulic support of the mining equipment. The middle part of the arc-shaped structure of the first hoop body 1222 is connected to one end of the cylindrical structure of the limiting member 121. In this way, the end of the monitor 2 close to the second frame 12 can protrude from one end of the cylindrical structure of the limiting member 121 and abut against the monitoring point, such as a solid coal seam structure, to collect signals.
