Description

Technical Field

[0001] This utility model relates to the field of mine roadway technology, and more specifically to a telescopic strut assembly for supporting underground mine roadways. Background Technology

[0002] Mine roadways refer to the tunnels and chambers excavated in underground coal seams, mainly used for mining coal or other mineral resources. According to their service scope and purpose, mine roadways can be divided into development roadways, preparation roadways, and mining roadways.

[0003] Due to the uneven ground surface in the tunnel, the contact area between the support strut base and the ground is small, resulting in poor stability. In addition, when geological conditions are unfavorable (such as soft rock deformation, groundwater softening of the foundation, or a sudden increase in surrounding rock pressure caused by high ground stress), the support struts in the tunnel are prone to collapse, resulting in insufficient support force and increasing the risk of tunnel collapse. Currently, when a collapse occurs, inspection personnel cannot quickly obtain this information. Even after it is discovered, due to the many bends in the tunnel and poor signal transmission, inspection personnel cannot quickly spread the information to other staff. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a telescopic strut assembly for mine roadway support to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a telescopic strut assembly for support of underground mine roadways, comprising a mounting base and a transmission unit. A receiving plate is provided on the top of the mounting base, and a support strut is provided on the top of the receiving plate. A fixing plate is provided inside the mounting base, and a support assembly is installed on the fixing plate. A monitoring unit is provided at the bottom of the support assembly. The support assembly is used to provide stable support for the bottom of the mounting base, the monitoring unit is used to monitor the settlement of the mounting base, and the transmission unit is used to transmit the monitoring results of the monitoring unit to inspection personnel and to provide early warning.

[0006] Preferably, the mounting base is a circumferential cylindrical shell structure with an open top. A limiting step is provided extending inward from the opening of the mounting base. The receiving plate is located at the top of the limiting step, and the receiving plate and the limiting step are fixedly connected by bolts.

[0007] Preferably, the bottom end of the support rod is fixedly connected to the top of the support plate, and a stabilizing block is welded between the support rod and the support plate. The stabilizing block has a trapezoidal block structure, and multiple stabilizing blocks are evenly arranged.

[0008] Preferably, the outer surface of the fixing plate is fixedly connected to the inner wall of the mounting base. Multiple support components are provided, and the multiple support components are evenly distributed inside the mounting base. Each support component includes a support leg, and a threaded post is fixedly connected to the top of the support leg. The bottom end of the support leg passes through the bottom of the mounting base and extends downward. The top end of the threaded post passes through the top of the fixing plate and extends upward. The threaded post is threadedly connected to the fixing plate, and a cross groove is provided at the top end of the threaded post.

[0009] Preferably, the monitoring unit includes a pressure sensor and a signal transmitting module, the pressure sensor and the signal transmitting module are electrically connected, the propagation unit is installed at the corner of the alley, the propagation unit includes a base station and a buzzer alarm, the base station and the buzzer alarm are electrically connected.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. Workers can adjust the threaded column according to the terrain's unevenness to make it rotate around its own axis. The rotation of the threaded column drives the support leg to rotate synchronously around its own axis. While rotating, the support leg moves linearly along its own axis, thereby changing the length of the support leg extending outward from the mounting base. Even on uneven ground, multiple support legs can be made to contact the ground at their bottom ends, thus achieving stable support for the support strut.

[0012] 2. This utility model has a transmission unit installed at the bend of the tunnel. When the ground at the support rod collapses, the inspection personnel can receive radio waves no matter where they are in the tunnel, so that they can quickly rush to the collapse site for investigation. This effectively avoids the problem that the inspection personnel cannot quickly obtain information due to the many bends in the tunnel and poor signal transmission, thus improving safety. In addition, after the base station receives the radio waves, it can control the buzzer alarm to sound an alarm. The staff in any position in the tunnel can hear the alarm and can evacuate quickly.

Detailed Implementation

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The telescopic strut assembly for mine roadway support involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] This utility model provides a telescopic strut assembly for support of underground mine roadways, including a mounting base 1 and a transmission unit 6. The mounting base 1 is provided with a receiving plate 2 on top, and a support strut 3 is provided on top of the receiving plate 2. A fixing plate 4 is provided inside the mounting base 1, and a support assembly 5 is installed on the fixing plate 4. A monitoring unit 7 is provided at the bottom of the support assembly 5. The support assembly 5 is used to provide stable support for the bottom of the mounting base 1, the monitoring unit 7 is used to monitor the settlement of the mounting base 1, and the transmission unit 6 is used to transmit the monitoring results of the monitoring unit 7 to the inspection personnel and to provide early warning.

[0022] Furthermore, the mounting base 1 has a circumferential cylindrical shell structure with an open top. A limiting step 11 extends inward from the opening of the mounting base 1. The receiving plate 2 is located on top of the limiting step 11. The receiving plate 2 and the limiting step 11 are fixedly connected by bolts. The bottom end of the support rod 3 is fixedly connected to the top of the receiving plate 2. A stabilizing block 31 is also welded between the support rod 3 and the receiving plate 2. The stabilizing block 31 has a trapezoidal block structure. Multiple stabilizing blocks 31 are evenly arranged. The stabilizing blocks 31 are used to improve the stability and connection strength between the support rod 3 and the receiving plate 2. The support rod 3 is a telescopic and adjustable structure and can provide support for the inner wall of the tunnel. The support rod 3 is existing technology in the mining field and will not be described in detail here.

[0023] Furthermore, the outer surface of the fixing plate 4 is fixedly connected to the inner wall of the mounting base 1. Multiple support components 5 are provided, and the multiple support components 5 are evenly distributed inside the mounting base 1. The support component 5 includes a support leg 51. A threaded post 52 is fixedly connected to the top of the support leg 51. The bottom end of the support leg 51 passes through the bottom of the mounting base 1 and extends downward. The top end of the threaded post 52 passes through the top of the fixing plate 4 and extends upward. The threaded post 52 is threadedly connected to the fixing plate 4. A cross groove 53 is opened at the top of the threaded post 52. The operator can insert a screwdriver into the cross groove 53 and screw the threaded post 52 to make it rotate around its own axis. The rotation of the threaded post 52 drives the support leg 51 to rotate synchronously around its own axis. At the same time, the support leg 51 moves linearly along its own axis.

[0024] Furthermore, the monitoring unit 7 includes a pressure sensor 71 and a signal transmission module 72, which are electrically connected. The propagation unit 6 is installed at the corner of the alleyway and includes a base station 61 and a buzzer alarm 62, which are electrically connected.

[0025] The working principle of this utility model is as follows: According to the unevenness of the terrain, the staff adjusts the length of the support component 5 extending outward from the mounting base 1. During adjustment, the staff inserts a screwdriver into the cross groove 53 and screws the threaded post 52 to make it rotate around its own axis. The rotation of the threaded post 52 drives the support leg 51 to rotate synchronously around its own axis. Since the threaded post 52 is threadedly connected to the fixing plate 4, the support leg 51 extends outward from the mounting base 1 while rotating. If the support leg 51 is to be retracted into the mounting base 1, the staff screws the threaded post 52 in the opposite direction. After the adjustment is completed, even on uneven ground, the bottom ends of multiple support legs 51 can contact the ground, thereby achieving stable support for the support rod 3.

[0026] When the ground collapses, the pressure sensor 71 senses the change in pressure value and transmits this information to the signal transmitting module 72 in the form of an electrical signal. The signal transmitting module 72 then transmits the information outward in the form of radio waves. The nearest base station 61 receives the radio waves and transmits them to other adjacent base stations 61, and so on. All base stations 61 receive the radio waves. At this time, the inspection personnel can receive the radio waves through the communication equipment at any location in the tunnel and can quickly rush to the collapse site for investigation.

[0027] After observation, if the collapse is serious, the inspection personnel can transmit radio waves through the communication equipment. The nearest base station 61 receives the radio waves and transmits them to other adjacent base stations 61. All base stations 61 receive the radio waves, and after receiving the radio waves, the base station 61 controls the buzzer alarm 62 to sound an alarm. Workers at any location in the tunnel can hear the alarm and evacuate quickly.
