DETAILED DESCRIPTION

[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0019] Example 1: Figures 1 to 5 As shown, a measuring device for coal mine exploration of the utility model comprises an exploration measuring instrument 1 and an installation platform 11, wherein the exploration measuring instrument 1 is installed at the upper end of the installation platform 11, and a plurality of vertical frames 12 are evenly and fixedly connected to the surrounding side of the installation platform 11. For example, there are three vertical frames 12, and the three vertical frames 12 are all connected with locking mechanisms for sliding up and down inside, and the lower end of the locking mechanisms is installed with supporting mechanisms, and the locking mechanisms include a U-shaped mounting block 13 connected with the vertical sliding of the vertical frame 12, and the U-shaped mounting block 13 is internally connected with two rotating shafts 14 for sliding, and the two rotating shafts 14 are fixedly connected with the limiting prism 15 on the side away from each other, and the two rotating shafts 14 are installed with elastic components on the side close to each other, and the U-shaped mounting block 13 is provided with a rotating groove 16 matching the limiting prism 15, and the side of the vertical frame 12 is provided with a plurality of slots 17 matching the limiting prism 15, and a protective component is installed between two adjacent vertical frames 12.

[0020] It should be noted that when the locking mechanism is in the locking position (when the operator does not apply a squeezing force to the limiting prism 15), the limiting prism 15 will move toward the slot under the action of the elastic force of the elastic component, and the limiting prism 15 is fixedly installed in the slot 17. When the locking mechanism is in the release position (when the operator applies a squeezing force to the two limiting prisms 15 to approach each other), the elastic component is compressed, the limiting prism 15 is separated from the slot 17 and rotated to fit in the rotation groove 16, so that the support mechanism can slide relative to the vertical frame 12, and the support mechanism can also rotate along the circumference of the rotation shaft 14.

[0021] In the initial state, the support mechanism is located inside the vertical frame 12, and the U-shaped mounting block 13 is locked by the locking mechanism. At this time, the limiting prism 15 is located inside the slot 17. A plurality of side ribs are fixedly connected to the circumference of the limiting prism 15, so that the rotating shaft 14 cannot rotate after the side ribs are inserted into the slot 17, and the U-shaped mounting block 13 cannot move. At the same time, the side ribs are aligned with different side rib grooves of the slot 17, which will make the rotating shaft 14 rotate at different angles. At this time, the protective component can also protect the exploration and measurement instrument 1;

[0022] When in use, the rebound force of the elastic component is overcome to drive the two rotating shafts 14 closer to each other, so that the limiting prism 15 can exit the slot 17 and enter the rotating groove 16, so that the limiting prism 15 can rotate inside the rotating groove 16, and the U-shaped mounting block 13 can also slide up and down to adjust the height of the supporting mechanism. After adjustment, releasing the rebound of the elastic component will make the limiting prism 15 align with the slot 17 and insert it into it, so that the U-shaped mounting block 13 and the rotating shaft 14 can be limited and locked, and the angle and height of the supporting mechanism can be adjusted, so as to facilitate the position of the exploration and measuring instrument 1 for different terrains and make it more convenient for workers to operate.

[0023] It can be understood that the operator can apply an extrusion force to the two limiting prisms 15 to move them closer to each other, so that the two rotating shafts 14 move in a direction closer to each other, thereby allowing the limiting prisms 15 to exit the slot 17 and enter the rotating groove 16. At this time, the U-shaped mounting block 13 is released from the limit. Since the U-shaped mounting block 13 is connected to the supporting mechanism, the U-shaped mounting block 13 and the supporting mechanism can slide up and down synchronously, and the rotating shaft 14 can also rotate to adjust the angle of the supporting mechanism.

[0024] After the operator releases the external force on the limiting prism 15, the limiting prism 15 can be aligned with the slot 17 at the corresponding position so that the limiting prism 15 can be inserted into the slot 17 under the elastic force of the elastic component. The limiting prism 15 is non-rotatably connected to the slot 17, thereby limiting the movement and rotation of the supporting mechanism.

[0025] The utility model can store the support mechanism inside the vertical frame 12 when not in use, and protect the exploration and measurement instrument 1 through the protective component. When in use, the height and rotation angle of the support mechanism can be adjusted by only overcoming the resilience of the elastic component, thereby making it more convenient and quick for workers to operate the support mechanism.

[0026] Embodiment 2: Based on Embodiment 1, further improvement is made, the support mechanism comprises a support rod 20 fixedly connected to the rotating shaft 14, the elastic component is installed between the two support rods 20, the lower ends of the two support rods 20 are slidably connected to a cross plate 21, the lower end of the cross plate 21 is rotatably connected to an insert block 22, the insert block 22 is fixedly connected to an abutment block 23 on the side close to the exploration and measurement instrument 1, and a threaded rod 24 is installed between the insert block 22 and the cross plate 21;

[0027] Under normal circumstances, the elastic component drives the two support rods 20 to move away from each other, thereby moving the rotating shaft 14 and the limiting prism 15 away from each other, so that the limiting prism 15 can be inserted into the slot 17 to play a locking role, thereby stabilizing the locking of the support mechanism, so that the plug block 22 can be stably inserted into the ground, and the threaded rod 24 can lock the cross plate 21 and the plug block 22 to prevent the plug block 22 from rotating. The abutment block 23 can increase the contact area of ​​the inclined plug block 22 inserted into the soil, thereby increasing the stability of the plug block 22.

[0028] The elastic component includes a slide 25 fixedly connected to the side of the support rod 20, two slides 25 close to each other are slidably connected, and a spring 26 located inside the slide 25 is fixedly installed on one side of the two support rods 20 close to each other; the two slides 25 can protect the spring 26, so that when the two support rods 20 overcome the rebound force of the spring 26 and approach each other, the two slides 25 slide close to each other.

[0029] A flat handle 27 is fixedly connected to the side of the threaded rod 24; the flat handle 27 can easily drive the threaded rod 24 to rotate, thereby adjusting the angle of the plug block 22, and can prevent the plug block 22 from being displaced when the threaded rod 24 is connected.

[0030] The protective component includes a mounting tube 28 that is slidably connected to the vertical frame 12, and the upper and lower ends of the mounting tube 28 are fixedly connected to the limit plates 29. An opening is opened on the side of the mounting tube 28, and a sliding mounting plate 30 is slidably connected to the mounting tube 28 up and down. The two sliding mounting plates 30 are close to each other and extend out of the mounting tube 28 on one side to install a protective folding cloth 31, and the upper ends of the protective folding cloth 31 are fixedly installed on the mounting tube 28 on both sides; when the supporting mechanism is located inside the vertical frame 12, the U-shaped mounting block 13 will slide the mounting tube 28 upward under the action of the limit plate 29, and then the mounting tube 28 extends out of the vertical frame 12, and the sliding mounting plate 30 is slidably connected to the mounting tube 28, so the sliding mounting plate 30 slides downward along the opening under the action of its own weight. Since the upper end of the protective folding cloth 31 is fixed to the mounting tube 28, the sliding mounting plate 30 will open the protective folding cloth 31 when it slides downward to cover the exploration and measurement instrument 1, so as to prevent dust from blocking the lens or foreign objects from scratching the exploration and measurement instrument 1.

[0031] A lifting rod 32 is fixedly connected between the two limit plates 29 located above the vertical frame 12; the support mechanism is stably installed inside the vertical frame 12 through a locking mechanism, and the limit plates 29 play a limiting role when the mounting tube 28 slides upward, so the entire device can be driven to move through the lifting rod 32, so that the exploration and measurement instrument 1 faces upward to avoid tilting and accidental collision.
