Description

Technical Field

[0001] This utility model relates to the technical field of rock compressive strength testing equipment for geotechnical engineering, specifically a protective device for rock compressive strength testing. Background Technology

[0002] The rock compressive strength testing equipment is mainly used for testing the compressive strength of rocks and rock masses. This testing machine uses electro-hydraulic loading, and the force measurement system is a microcomputer control system with dual-screen display capabilities. It can digitally display the loading speed and force value, automatically store data for easy retrieval, and automatically print results. It has overload protection; when the force value exceeds 3% of the full scale, it will automatically shut down and cut off the power. It also has peak hold and compressive strength conversion capabilities, and the loading speed can be manually controlled.

[0003] Traditional rock compressive strength tests pose certain safety hazards during the testing process. In particular, when the rock compressive strength is high, the rock sample may suddenly break, causing broken samples or instrument parts to fly out, which may injure the operators. Therefore, the safety of use is relatively low. Utility Model Content

[0004] The purpose of this invention is to provide a protective device for rock compressive strength testing, which solves the problem that traditional rock presses have certain safety hazards during the testing process, especially when the rock compressive strength is high, the rock sample may suddenly break, resulting in broken samples or instrument parts flying, causing injury to the operator, and the safety of use is relatively low.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a protective device for rock compressive strength testing, including a housing. Several sets of self-locking casters are installed on the lower surface of the housing. A testing mechanism is installed on the upper surface of the housing. A pressure chamber is installed on the upper surface of the housing and is located below the testing end of the testing mechanism. A protective mechanism is installed on one side of the housing, and the protective end of the protective mechanism is located around the testing end of the testing mechanism and the pressure chamber.

[0006] Furthermore, the protective mechanism includes a mounting plate, which is fixedly mounted on one side of the chassis. A mounting groove is formed on the upper surface of the mounting plate, and a lead screw is rotatably connected inside the mounting groove. A motor is fixedly mounted on one end of the mounting plate, and the output end of the motor is fixedly connected to one end of the lead screw. A movable plate is slidably connected inside the mounting groove, and the interior of the movable plate is threadedly connected to the lead screw. A connecting plate is fixedly mounted on the upper surface of the movable plate, and a transparent protective plate is fixedly mounted on one end of the connecting plate. The transparent protective plate can enclose the testing mechanism and the testing end of the pressure chamber. Furthermore, a reinforcing plate is fixedly installed on the lower surface of the mounting plate, and one end of the reinforcing plate is fixedly installed on the outer surface of the chassis; When the rock pressure tester performs geotechnical tests, the motor is started, driving the lead screw to rotate. Since the moving plate is threadedly connected to the lead screw, the rotation of the lead screw drives the moving plate to slide horizontally along the mounting groove. The moving plate pushes the transparent protective plate to move through the connecting plate, so that it covers the test area of ​​the test mechanism and pressure chamber, forming a physical isolation. The transparent protective plate can block rock samples or broken parts that may splash during the test, while not affecting the observation of the test process. After the test, the motor reverses, and the protective plate returns to its original position, thus preventing accidental contact or injury from splashes and improving the safety level of the laboratory.

[0007] Furthermore, two sets of auxiliary guide wheels are fixedly installed on both sides of the transparent protective plate; Furthermore, the auxiliary guide wheel abuts against the upper surface of the mounting plate and the chassis; Meanwhile, as the transparent protective plate moves, the auxiliary guide wheels roll along the mounting plate and the upper surface of the chassis to ensure the smooth movement of the transparent protective plate and improve the stability of its movement.

[0008] Furthermore, the transparent protective panel includes a first panel connected to the connecting panel, and two second panels disposed on both sides of the first panel.

[0009] Furthermore, one end of one of the second plates is rotatably connected to a third plate, and the free end of the third plate is connected to the end of another second plate away from the first plate by fasteners.

[0010] Furthermore, a first limiting groove is provided on the upper end face of the free end of the third plate, and a second limiting groove is provided on the upper end face of the corresponding connected second plate. Both the first limiting groove and the second limiting groove have a T-shaped cross-section. When the free end of the third plate is engaged with the end of the corresponding second plate, the first limiting groove and the second limiting groove are connected to form a locking groove with an I-shaped cross-section. The fastener is a pin with a cross-sectional shape that matches the locking groove.

[0011] This utility model has the following beneficial effects: (1) When the rock pressure machine is used for geotechnical testing, the motor is started and the lead screw is rotated. Since the moving plate is connected to the lead screw by threads, the rotation of the lead screw will drive the moving plate to slide horizontally along the mounting groove. The moving plate pushes the transparent protective plate to move through the connecting plate, so that it covers the test area of ​​the test mechanism and the pressure chamber, forming a physical isolation. The transparent protective plate can block rock samples or broken parts that may be splashed during the test, and does not affect the observation of the test process. After the test is completed, the motor reverses and the protective plate returns to its original position, so as to prevent personnel from accidentally touching or being injured by splashed objects and improve the safety level of the laboratory.

[0012] (2) When the transparent protective plate moves simultaneously, the auxiliary guide wheel rolls along the mounting plate and the upper surface of the chassis to ensure the smooth movement of the transparent protective plate and improve the stability of the movement of the transparent protective plate.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4As shown, this utility model is a protective device for rock compressive strength testing, including a housing 1. Several sets of self-locking casters 2 are installed on the lower surface of the housing 1. A testing mechanism 3 is installed on the upper surface of the housing 1. A pressure chamber 4 is installed on the upper surface of the housing 1. The pressure chamber 4 is located below the testing end of the testing mechanism 3. A protective mechanism 5 is installed on one side of the housing 1. The protective end of the protective mechanism 5 is located around the testing end of the testing mechanism 3 and the pressure chamber 4.

[0018] The protective mechanism 5 includes a mounting plate 501, which is fixedly mounted on one side of the housing 1. The upper surface of the mounting plate 501 has a mounting groove 502. A lead screw 503 is rotatably connected inside the mounting groove 502. A motor 504 is fixedly mounted on one end of the mounting plate 501. The output end of the motor 504 is fixedly connected to one end of the lead screw 503. A movable plate 506 is slidably connected inside the mounting groove 502. The interior of the movable plate 506 is threadedly connected to the lead screw 503. A connecting plate 507 is fixedly mounted on the upper surface of the movable plate 506. A transparent protective plate 508 is fixedly mounted on one end of the connecting plate 507. The transparent protective plate 508 can surround the test end of the test mechanism 3 and the pressure chamber 4. A reinforcing plate 505 is fixedly installed on the lower surface of the mounting plate 501, and one end of the reinforcing plate 505 is fixedly installed on the outer surface of the chassis 1. When the rock pressure tester performs geotechnical tests, the motor 504 is started, driving the lead screw 503 to rotate. Since the moving plate 506 is threadedly connected to the lead screw 503, the rotation of the lead screw 503 will drive the moving plate 506 to slide horizontally along the mounting groove 502. The moving plate 506 pushes the transparent protective plate 508 to move through the connecting plate 507, so that it covers the test area of ​​the test mechanism 3 and the pressure chamber 4, forming a physical isolation. The transparent protective plate 508 can block soil samples, high-pressure liquids or broken parts that may splash during the test, while not affecting the observation of the test process. After the test, the motor 504 reverses, and the protective plate returns to its original position, thus preventing personnel from accidentally touching or being injured by splashes and improving the safety level of the laboratory.

[0019] Two sets of auxiliary guide wheels 509 are fixedly installed on both sides of the transparent protective plate 508; The auxiliary guide wheel 509 abuts against the upper surface of the mounting plate 501 and the chassis 1; Simultaneously, as the transparent protective plate 508 moves, the auxiliary guide wheel 509 rolls along the mounting plate 501 and the upper surface of the chassis 1, ensuring the smooth movement of the transparent protective plate 508 and improving the stability of its movement. Preferably, the transparent protective plate 508 includes a first plate connected to the connecting plate 507, and two second plates disposed on both sides of the first plate.

[0020] Further preferably, to provide more flexible and enhanced protection, the transparent protective plate 508 further includes an openable third plate, the lower end of which is higher than the upper end of the auxiliary guide wheel 509. This third plate is rotatably connected (e.g., via a hinge) to the end of one of the second plates furthest from the first plate. The free end of the third plate is connected to the end of another second plate furthest from the first plate via fasteners (e.g., bolts, pins). Optionally, a first limiting groove is formed on the upper surface of the free end of the third plate, and a second limiting groove is formed on the upper surface of the corresponding end of the second plate. Both the first and second limiting grooves have a T-shaped cross-section. When the free end of the third plate mates with the end of the corresponding second plate, the first and second limiting grooves connect and mate to form a locking groove with an I-shaped cross-section. The fastener is a pin with a cross-sectional shape adapted to the locking groove. The thickness of the pin is greater than the depth of the locking groove.

[0021] When enhanced sealing or protective height is required, the operator can manually rotate the third plate around its axis to cover one end of the second plate on the other side. The free end of the third plate is secured to the second plate with fasteners, firmly locking it in the closed position and forming a more complete and less penetrable protective barrier. For low-risk tests or those requiring only basic protection, the third plate can remain open, attached to or suspended from the side of the connected second plate. This minimizes obstruction of vision, facilitating operator observation of the test area and equipment adjustments while maintaining basic side protection. For high-pressure tests, tests prone to debris splashing, or tests involving brittle rocks that may suddenly fracture, the operator can quickly close and lock the third plate for further enhanced safety.

[0022] In use, when the rock pressure testing machine is conducting a geotechnical test, the motor 504 is started, which drives the lead screw 503 to rotate. Since the moving plate 506 is threadedly connected to the lead screw 503, the rotation of the lead screw 503 will drive the moving plate 506 to slide horizontally along the mounting groove 502. The moving plate 506 pushes the transparent protective plate 508 to move through the connecting plate 507, so that it covers the test area of ​​the test mechanism 3 and the pressure chamber 4, forming a physical isolation. The transparent protective plate 508 can block soil samples, high-pressure liquids or broken parts that may splash during the test, while not affecting the observation of the test process. After the test, the motor 504 reverses, and the protective plate returns to its original position, thus preventing accidental contact or injury from splashes and improving the safety level of the laboratory. Meanwhile, when the transparent protective plate 508 moves, the auxiliary guide wheel 509 rolls along the mounting plate 501 and the upper surface of the chassis 1 to ensure the smooth movement of the transparent protective plate 508 and improve the stability of the movement of the transparent protective plate 508.
