[0002] Geotechnical refers to any kind of rock and soil that makes up the earth's crust from the perspective of engineering construction. The existing rock test devices do not have the function of limiting the test block, which is likely to cause the displacement of the test block during the test, thus affecting the test results.

[0003] In the prior art, the patent (CN215866156U) discloses a rock test device for coal mine geological exploration, including a bottom box. A test box is fixedly connected to the top of the bottom box. A double-shaft motor is fixedly connected to the center of the inner cavity of the bottom box. Threaded rods are fixedly connected to the output shafts on both sides of the double-shaft motor. Threaded sleeves are threadedly connected to the surfaces of the threaded rods. An L-shaped rod is fixedly connected to the top of the threaded sleeve. Through the settings of the double-shaft motor, the threaded rods and the threaded sleeves, the L-shaped rod and the clamping plate can be driven to move relatively, so as to realize the positioning and fixing of the test block, thus avoiding the displacement of the test block due to extrusion during the test, which affects the test results. Then, an electric push rod is used to push the support plate and the pressure plate to extrude the test block. At the same time, the extrusion plate will extrude the pressure sensor. At this time, the pressure sensor will record the pressure data received by the rock, which is convenient for obtaining accurate test data.

The clamping mechanism 105 includes a biaxial motor 115, two threaded rods 116, two threaded sleeves 117, two clamping plates 118 and a sliding rod 119.

[0023] For this specific embodiment, the clamping mechanism 105 is fixedly connected to the test box 102, the pressure transmission mechanism 103 is fixedly connected to the test box 102, the test box 102 is fixedly connected to the bottom box 101, the placement plate 109 is fixedly connected to the drive shaft 107 and is located at the upper end of the drive shaft 107. The mounting plate 108 is rotatably connected to the drive shaft 107. The lower end of the drive shaft 107 is fixedly connected to the output end of the servo motor 106. The servo motor 106 is fixedly connected to the bottom box 101. The box door 111 is rotatably connected to the box body 110. The box body 110 is fixedly connected to the bottom box 101. The pressing plate 114 is fixedly connected to the support plate 113. The support plate 113 is fixedly connected to the electric push rod 112. The electric push rod 112 is fixedly connected to the box body 110. The sliding rod 119 is fixedly connected to the box body 110. Each clamping plate 118 is respectively fixedly connected to the corresponding threaded sleeve 117. Each threaded sleeve 117 is respectively rotatably connected to the corresponding threaded rod 116. One end of each of the two threaded rods 116 is rotatably connected to the box body 110. The other end of each of the two threaded rods 116 is fixedly connected to the output end of the biaxial motor 115. The biaxial motor 115 is fixedly connected to the box body 110. The currently provided servo motor 106 can drive the drive shaft 107 and the placement plate 109 to rotate according to the clamping needs, adjust the placement position and angle of the rock, and avoid the clamping mechanism 105 clamping the protruding part of the rock, affecting the test safety. This design solves the problem that when detecting and testing rocks of different shapes and sizes, the clamping effect on the rocks is easily affected and the rocks are prone to bounce during the test.

[0024] Among them, the clamping mechanism 105 is located on the inner wall of the test chamber 102, the pressure transmission mechanism 103 is located above the test chamber 102, the test chamber 102 is located above the bottom case 101, the placement plate 109 is located at the upper end of the drive shaft 107, the mounting plate 108 is located on the circumferential side of the drive shaft 107, and the servo motor 106 is located on the inner wall of the bottom case 101. Due to the irregularity of each rock, when clamping and fixing the rock, it is necessary to adjust the angle of the rock. By driving the drive shaft 107 and the placement plate 109 with the servo motor 106, the placement angle of the rock can be gradually adjusted, facilitating subsequent clamping.

[0025] Secondly, the box door 111 is located on one side of the box body 110, the box body 110 is located above the bottom case 101, the pressing plate 114 is located below the support plate 113, the support plate 113 is located below the electric push rod 112, and the electric push rod 112 is located above the box body 110. After the two clamping plates 118 clamp the rock, the electric push rod 112 is activated to drive the support plate 113 and the pressing plate 114 to squeeze the rock. Since a pressure sensor is provided in the pressing plate 114, the hardness of the rock can be detected. After the pressing is completed, the support plate 113 and the pressing plate 114 are retracted, and the biaxial motor 115 retracts and releases the two clamping plates 118, and the staff removes the rock from the placement plate 109 again.

[0026] At the same time, the slide rod 119 is located inside the box body 110. Each clamping plate 118 is respectively located on one side of the corresponding thread sleeve 117, and each thread sleeve 117 is respectively located on one side of the corresponding threaded rod 116. One end of the two threaded rods 116 is located inside the box body 110, and the biaxial motor 115 is located inside the box body 110. The setting of the slide rod 119 restricts the movement of the two thread sleeves 117, preventing the thread sleeves 117 and the clamping plates 118 from deflecting in angle during the movement of the thread sleeves 117 guided by the rotation of the threaded rods 116, which affects the clamping of the rock.

[0027] In this embodiment, the servo motor 106 provided can drive the drive shaft 107 and the placement disk 109 to rotate according to the clamping needs, adjust the placement position and angle of the rock, and avoid the clamping mechanism 105 clamping the protruding part of the rock, which affects the test safety. This design solves the problem that when detecting rocks of different shapes and sizes, the clamping effect on the rocks is easily affected and the rocks are prone to bounce during the test. Due to the irregularity of each rock, when clamping and fixing the rock, it is necessary to adjust the angle of the rock. By driving the drive shaft 107 and the placement disk 109 with the servo motor 106, the placement angle of the rock can be gradually adjusted, so as to facilitate subsequent clamping. After the two clamping plates 118 clamp the rock, the electric push rod 112 is activated to drive the support plate 113 and the pressing plate 114 to squeeze the rock. Since a pressure sensor is provided in the pressing plate 114, the hardness of the rock can be detected. After the pressing is completed, the support plate 113 and the pressing plate 114 are retracted, the biaxial motor 115 retracts and releases the two clamping plates 118, and the staff removes the rock from the placement disk 109 again. The setting of the sliding rod 119 restricts the movement of the two threaded sleeves 117, and avoids the angle deflection of the threaded sleeve 117 and the clamping plate 118 during the movement of the threaded sleeve 117 guided by the rotation of the threaded rod 116, which affects the clamping of the rock.
