Description

Technical Field

[0001] This utility model relates to the field of rock compressive strength testing technology, and in particular to a rock compressive strength tester. Background Technology

[0002] Rock compressive strength testing is an important experimental method for evaluating the ability of rocks to resist failure under compression, and it is widely used in fields such as geological engineering, mining, and civil engineering. This test allows us to obtain the basic mechanical parameters of rock materials, providing a scientific basis for design and construction.

[0003] Existing rock compressive strength testers typically place the rock on a pressure platform and then apply pressure to the rock with a pressure block to test its compressive strength. However, due to the irregular shape of the rock, it may move during the pressure test, affecting the accuracy of the test. Furthermore, the rock may easily break and splash out, causing injury to surrounding personnel and equipment, which is quite dangerous.

[0004] Therefore, a rock compressive strength tester has now been developed that can limit and protect the rock, ensuring the accuracy and safety of the test. Utility Model Content

[0005] To overcome the shortcomings of existing rock compressive strength testers, such as the possibility of rock movement during pressure testing affecting test accuracy, and the risk of rock fragmentation injuring nearby workers, this invention provides a rock compressive strength tester that can limit and protect the rock, ensuring test accuracy and safety.

[0006] The technical solution is as follows: A rock compressive strength tester includes a base, a protective frame, a shielding door, guide rods, electric push rods, a sliding plate, a pressure sensor, a pressure block, a mounting block, a slide rod, a second telescopic spring, a vent pipe, an air inlet block, and protective components. A protective frame is connected to the upper side of the base. A shielding door is rotatably connected to the front left side of the protective frame. Multiple guide rods are connected between the protective frame and the base. An electric push rod is connected to the upper side of the protective frame. A sliding plate is connected to the telescopic end of the electric push rod. The guide rods are all slidably connected to the sliding plate. A pressure sensor is connected to the lower middle part of the sliding plate. A pressure block is connected to the lower side of the pressure sensor. A mounting block is connected to the upper part of the base. Multiple slide rods are slidably connected to the mounting block. A second telescopic spring is connected between each slide rod and the mounting block. Multiple vent pipes are connected to the lower side of the mounting block. Each vent pipe is located below an adjacent slide rod. An air inlet block is connected between the lower sides of the vent pipes. The air inlet block is connected to the base. A protective component is provided on the sliding plate to prevent rock debris from splashing out.

[0007] Preferably, a base plate is provided on the lower side of the base.

[0008] Ideally, the shielding door should be made of a transparent material.

[0009] Preferably, the upper side of the slide bar is semi-circular.

[0010] As a preferred embodiment, it also includes protective cotton, with a threaded connection on the underside of the pressure block.

[0011] Preferably, the protective assembly includes a protective frame and a first telescopic spring. The protective frame is slidably connected to the lower side of the sliding plate, and the first telescopic spring is connected to both the left and right sides of the protective frame and the sliding plate.

[0012] The beneficial effects of this utility model are as follows: By placing a rock into the mounting block, the sliding rod in contact with the rock is squeezed and moves downward. Then, air is introduced into the ventilation pipe through the air inlet block, so that the sliding rod not in contact with the rock remains upward. Then, the electric actuator is activated to push the sliding plate downward. The protective frame first contacts the upper side of the mounting block and closes the mounting block. This achieves the effect of limiting the rock and protecting the rock, ensuring the accuracy and safety of the test. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] A rock compressive strength tester, such as Figures 1-5As shown, the device includes a base 1, a protective frame 2, a shielding door 3, guide rods 4, electric push rods 5, a sliding plate 6, a pressure sensor 7, a pressure block 8, protective cotton 9, a mounting block 12, a sliding rod 13, a second telescopic spring 14, a vent pipe 15, an air inlet block 16, and protective components. The protective frame 2 is connected to the upper side of the base 1, and a chassis is provided on the lower side of the base 1 to improve placement stability. The shielding door 3 is rotatably connected to the front left side of the protective frame 2. The shielding door 3 is made of transparent material to facilitate viewing the internal situation. Four guide rods 4 are connected between the protective frame 2 and the base 1. The electric push rod 5 is connected to the upper side of the protective frame 2. The sliding plate 6 is connected to the telescopic end of the electric push rod 5. All guide rods 4 are slidably connected to the sliding plate 6. The pressure sensor 7 is connected to the lower middle part of the sliding plate 6, and the pressure block 8 is connected to the lower side of the pressure sensor 7. The protective cotton 9 is threadedly connected to the lower side of the pressure block 8. The mounting block 12 is connected to the upper part of the base 1. Thirty-six sliding rods 13 are slidably connected to the mounting block 12. The upper side of each sliding rod 13 is semi-circular to facilitate adaptation to the rock surface. A second telescopic spring 14 is connected between each sliding rod 13 and the mounting block 12. Thirty-six ventilation pipes 15 are connected to the lower side of the mounting block 12. Each ventilation pipe 15 is located below an adjacent sliding rod 13. An air inlet block 16 is connected between the lower sides of each ventilation pipe 15. The air inlet block 16 is connected to the base 1. A protective component is provided on the sliding plate 6. The protective component includes a protective frame 10 and a first telescopic spring 11. The protective frame 10 is slidably connected to the lower side of the sliding plate 6. The first telescopic spring 11 is connected to both the left and right sides of the protective frame 10 and the sliding plate 6.

[0021] When using this invention, first place the base 1 in the rock compressive strength test area, then rotate and open the shielding door 3, place the rock into the mounting block 12, and the sliding rod 13 in contact with the rock is compressed and moves downward, causing the second telescopic spring 14 to compress and contract. Then, air is introduced into the vent pipe 15 through the air inlet block 16, keeping the sliding rod 13, which is not in contact with the rock, upward, thus limiting the rock's movement. Then, close the shielding door 3, and then activate the electric actuator 5 to push the sliding plate 6 downward. The guide rod... 4. The sliding plate 6 is guided. When the sliding plate 6 moves downward, the protective frame 10 first contacts the upper side of the mounting block 12 to close the mounting block 12, thereby preventing rocks from splashing out. Then, the first telescopic spring 11 is squeezed and contracted, causing the sliding plate 6 to continue to move downward, so that the protective cotton 9 on the pressure block 8 contacts the rock, which facilitates uniform pressure application. Then, the pressure block 8 continues to press down to apply pressure to the rock. The pressure sensor 7 detects the pressure on the pressure block 8 and then obtains the rock compressive strength based on the rock condition.
