[0040] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.

[0041] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0042] See also Figure 1-5 This embodiment provides a safety monitor for tunnel investigation, which mainly includes: a protective shell 100, a lifting assembly 200, a roller 300 and a monitoring terminal 500, etc.

[0043] like Figure 1-Figure 3 As shown in the figure, the protective shell 100 is a rectangular protective shell of the safety monitor in this embodiment, which is mainly used to protect the internal lifting component 200, roller 300, monitoring terminal 500 and other control and analysis components, etc., to prevent them from being damaged by the impact of falling rocks, debris, etc. in the tunnel. Figure 2 , Figure 3It can be seen that a top opening 101 and a bottom opening 103 are respectively provided on the top wall and the bottom wall of the protective shell 100. The top opening 101 is relatively deep, and a top plate 110 matching its shape and size is slidably embedded inside it. The top plate 110 is arranged horizontally, and its side faces are fitted with the inner wall of the top opening 101, and can slide up and down. In addition, a rectangular upper adjustment block 112 protrudes downward from the center of the lower surface of the top plate 110, which is convenient for connecting it with the lifting assembly 200. The bottom opening 103 is relatively shallow, and a bottom plate 130 is movably embedded inside the protective shell 100 above it. The bottom plate 130 is also arranged horizontally, and its side faces are fitted with the inner wall of the protective shell 100, and can slide up and down. In addition, a rectangular lower adjustment block 132 protrudes upward from the center of the upper surface of the bottom plate 130, which is convenient for connecting it with the lifting assembly 200. At the same time, a fixing plate 120 is fixedly embedded in the protective shell 100 between the top plate 110 and the bottom plate 130. The fixing plate 120 is also horizontally arranged, but its side is fixedly connected to the inner wall of the protective shell 100 to fix the position of the lifting assembly 200. In addition, a front box 140 is also arranged on the outer side of the front side wall of the protective shell 100. Figure 4 The interior of the front box 140 is used to set the motor 270 used for driving the lifting assembly 200.

[0044] like Figure 1-Figure 4 As shown in the figure, the lifting assembly 200 is disposed in the protective shell 100 and between the top plate 110 and the bottom plate 130. In this embodiment, the lifting assembly 200 switches the fixed state and the mobile state of the safety monitor by controlling the top plate 110 and the bottom plate 130 to rise or fall synchronously, thereby meeting the working needs of other components on the upper and lower sides. Figure 2 , Figure 3It can be seen that the lifting assembly 200 is mainly composed of a screw rod 250, a worm gear mechanism 260 and a motor 270. The screw rod 250 is vertically arranged, and its upper part is threadedly connected to the lower part of the upper adjustment block 112, and a matching threaded hole is provided at the lower part of the upper adjustment block 112; the lower part of the screw rod 250 is threadedly connected to the upper part of the lower adjustment block 132, and a matching threaded hole is also provided at the upper part of the lower adjustment block 132. According to the thread direction setting, when the screw rod 250 rotates clockwise, the upper adjustment block 112 and the lower adjustment block 132 rise synchronously; when the screw rod 250 rotates counterclockwise, the upper adjustment block 112 and the lower adjustment block 132 fall synchronously, and it can be seen that the top plate 110 and the bottom plate 130 also rise and fall synchronously. At the same time, in order to fix the position of the screw 250 and facilitate its rotation, the middle part of the screw 250 passes through the fixed plate 120 through the sleeved first bearing 290 and is rotatably connected thereto, so that the screw 250 can rotate relative to the fixed plate 120, but cannot move its relative position. The worm gear mechanism 260 is mainly composed of a worm wheel 262 and a worm 264. Among them, the worm wheel 262 is also fixedly sleeved on the screw 250 and is located above the first bearing 290, and rotates synchronously with the screw 250. The worm 264 is horizontally arranged in the front and rear directions, and its rear part is a threaded rod, which is meshed with the worm wheel 262 for transmission; the front part of the worm 264 is a bare rod without threads, which is rotatably connected to the front side wall of the protective shell 100 through the second bearing 292, and its front end extends out of the front side wall of the protective shell 100 and is fixedly connected to the output end of the motor 270. The motor 270 is fixedly arranged in the front box 140, and drives the rotation of the worm gear mechanism 260 through the worm 264, and further drives the rotation of the lead screw 250 fixedly connected to the worm wheel 262, thereby controlling the synchronous rise and fall of the top plate 110 and the bottom plate 130. When the two rise to the upper limit position, it is the fixed state of the safety monitor, and when the two fall to the lower limit position, it is the moving state of the safety monitor.

[0045] like Figure 2-Figure 4 As shown in , the roller 300 is fixedly arranged on the lower surface of the lower side of the bottom plate 130. The roller 300 provides convenient mobility for the safety monitor of this embodiment. When the lifting assembly 200 controls the bottom plate 130 to descend to the moving state of the safety monitor, the roller 300 can extend from the bottom opening 103 and contact the ground, thereby moving; when the lifting assembly 200 controls the bottom plate 130 to rise to the fixed state of the safety monitor, the roller 300 can be retracted from the bottom opening 103, and the bottom surface of the bottom wall of the protective shell 100 contacts the ground, thereby fixing it, and in order to increase the friction and enhance the stabilization effect, a layer of rubber pad 150 is also provided on the bottom surface of the bottom wall of the protective shell 100 to prevent sliding.

[0046] like Figure 1-Figure 3As shown in , the monitoring terminal 500 is fixedly arranged on the upper surface of the upper side of the top plate 110. The monitoring terminal 500 is used to collect environmental data, facilitate the analysis of the possibility of accidents such as tunnel collapse, and issue corresponding warning information to remind on-site workers to work carefully or evacuate the dangerous area in time. When the lifting assembly 200 controls the top plate 110 to descend to the mobile state of the safety monitor, the monitoring terminal 500 can be retracted from the top opening 101 to avoid protrusion, thereby facilitating movement, and is protected by the protective shell 100 to avoid damage to the monitoring terminal 500; when the lifting assembly 200 controls the top plate 110 to rise to the fixed state of the safety monitor, the monitoring terminal 500 can be extended from the top opening 101 to facilitate its normal monitoring work.

[0047] A specific implementation of this embodiment is: before use, the user controls the motor 270 to drive the worm gear mechanism 260 to rotate, the screw 250 to rotate, and the top plate 110 and the bottom plate 130 to descend synchronously, so as to retract the monitoring terminal 500 into the protective shell 100 and extend the roller 300 from the bottom of the protective shell 100; then, the user can safely and conveniently push the safety monitor to the specified position; after reaching the specified position, the user controls the motor 270 again to drive the worm gear mechanism 260 to rotate, the screw 250 to rotate, and the top plate 110 and the bottom plate 130 to rise synchronously, so as to retract the roller 300 into the protective shell 100 and extend the monitoring terminal 500 from the top of the protective shell 100, and then start monitoring.

[0048] In this embodiment, the safety monitor is provided with a lifting assembly 200, and relies on the screw 250 and the worm gear mechanism 260 in the lifting assembly 200 to cooperate with the top plate 110 to control the rise and fall of the monitoring terminal 500, thereby realizing the retraction of the monitoring terminal 500 in the moving state of the safety monitor and the extension of the monitoring terminal 500 in the fixed state, thereby solving the problem in the prior art that the safety monitor has an extended monitoring terminal, which is not convenient for transportation and storage, and is prone to collision during transportation, resulting in damage to the monitoring terminal, thereby affecting the service life of the device.

[0049] At the same time, in this embodiment, a lifting component 200 is provided, and the screw 250 and the worm gear mechanism 260 in the lifting component 200 cooperate with the base plate 130 to control the rise and fall of the roller 300, so as to realize the extension of the roller 300 in the moving state of the safety monitor and the retraction of the roller 300 in the fixed state. Therefore, the safety monitor of this embodiment will not be easily moved due to the influence of the roller 300 during the monitoring work, and its fixed state is more stable. The monitoring process avoids the influence of movement, and the monitoring data is more accurate and reliable.

[0050] In addition, in this embodiment, a circumferential sponge pad 232 is provided on the side of the bottom plate 130 to reduce the friction loss between the bottom plate 130 and the side wall of the protective shell 100, thereby preventing the protective effect of the protective shell 100 from being affected after long-term wear.

[0051] Preferably, if Figure 5 As shown in , in this embodiment, a groove 121 can also be provided on the fixing plate 120 to accommodate the threaded rod portion of the worm wheel 262 and the worm 264 in the worm gear mechanism 260, and the groove 121 is adapted to the shape of the worm gear mechanism 260, and is in the shape of a circle connected to a rectangle. At the same time, the rear end of the worm 264 is also a bald rod without threads, which is rotatably connected to the inner wall of the groove 121 through the third bearing 294. By providing a groove 121 of an adaptive shape, the position of the worm wheel 262 and the worm 264 in the worm gear mechanism 260 can be stabilized, thereby reducing the probability of displacement and dislocation after long-term use, so that the structure of the lifting assembly 200 of this embodiment is more stable and more durable.

[0052] Preferably, in this embodiment, a baffle 400 can also be set above the monitoring terminal 500 on the top plate 110. The baffle 400 is set by two support rods 410 symmetrically fixed on the upper surface of the top plate 110, and is mainly used to protect the top of the monitoring terminal 500 when it is fixed. Further, the shape and size of the baffle 400 can be designed to be compatible with the top opening 101, so that when the safety monitor is in a mobile state, the baffle 400 can seal the top opening 101, thereby preventing dust raised in the tunnel during the movement from entering the monitoring terminal 500, causing short circuits and other unexpected situations that affect its work. In addition, since the baffle 400 is a protective component on the top, it is particularly easy to be damaged. It is also possible to set a detachable threaded connection between the two support rods 410 and the top plate 110, and set a rubber sleeve 412 on the two support rods 410, so as to facilitate the disassembly and replacement of the baffle 400.

[0053] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
