Description

Technical Field

[0001] This utility model belongs to the field of rock testing technology, and in particular relates to a measuring device for rock test specimens. Background Technology

[0002] A measuring device for rock test specimens is a specialized device for the precise measurement of rock test specimens. It typically features high-precision measuring elements and a scientifically designed structure, enabling it to accurately measure various parameters of rock specimens, such as dimensions, deformation, and displacement. This provides crucial measurement data support for the study of rock mechanical properties and related engineering applications, helping researchers and engineers better understand the characteristics and behavior of rocks under different conditions.

[0003] Currently, rock measuring devices require a fixing device for stable installation during actual use. However, the existing fixing devices rely on manual operation, which is not only cumbersome but also requires a lot of time and effort for debugging and calibration. This not only increases the workload of operators but also greatly reduces the overall work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a measuring device for rock test specimens. By setting up a clamping mechanism, it solves the problem that the existing fixing device relies on manual operation, which is not only cumbersome but also requires a lot of time and effort for debugging and calibration. This not only increases the workload of operators but also greatly reduces the overall work efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a measuring device for rock test specimens, including a worktable, on which a clamping mechanism and a configuration mechanism are provided;

[0007] The clamping mechanism includes two rails fixedly connected to the top of the workbench, two sliding plates slidably connected to the outer surfaces of the two rails, an L-shaped seat fixedly connected to the top of each of the two sliding plates, and a rack groove on each of the two sliding plates. A fixing block is fixedly connected to the top plate of the workbench, and a hydraulic push rod is fitted on the fixing block. The output end of the hydraulic push rod is fixedly connected to the corresponding sliding plate. A rack is fixedly connected to the side of each of the two sliding plates that are close to each other. The two racks are slidably connected to the two rack grooves. A rotating rod is rotatably connected to the top of the workbench, and a gear is fitted on the outer wall of the rotating rod. The gear meshes with the two racks.

[0008] Furthermore, the configuration mechanism includes a base plate disposed at the bottom of the workbench. Two slide rails are fixedly connected to the top of the base plate, and the outer surfaces of the two slide rails are slidably connected to the workbench. A support rod is fixedly connected to the top of the base plate, and a fixing block is fixedly connected to the front of the support rod. A hydraulic push rod is sleeved on the fixing block. Two slide rods are fixedly connected to the top of the base plate, and a sliding plate is slidably connected to the outer walls of the two slide rods. The output end of the hydraulic push rod is fixedly connected to the sliding plate. A measuring element is disposed at the bottom of the sliding plate.

[0009] Furthermore, two L-shaped abutments are fixedly connected to the bottom of the second slide plate, and two U-shaped blocks are fixedly connected to the top of the base plate. Each of the two U-shaped blocks is rotatably connected to an L-shaped rod. One end of each of the two L-shaped rods is rotatably connected to a guide roller, and both guide rollers are in contact with the two L-shaped abutments. The other end of each of the two L-shaped rods is provided with a sliding groove. Sliding rods are fixedly connected to the left and right sides of the worktable. The left and right ends of the two sliding rods extend outside the two sliding grooves and are slidably connected to the two sliding grooves.

[0010] Furthermore, a second U-shaped block is fixedly connected to the top of the base plate, and a second sliding rod is fixedly connected to the back of the second U-shaped block. The second sliding rod passes through the worktable and is slidably connected to the worktable. The rear end of the second sliding rod is fixedly connected to a support rod. A spring is wound around the outer wall of the second sliding rod. One end of the spring is fixedly connected to the worktable, and the other end of the spring is fixedly connected to the support rod.

[0011] This utility model has the following beneficial effects:

[0012] 1. By setting up a clamping mechanism, when in use, the rock specimen is placed between two L-shaped seats. Then, the hydraulic push rod is activated, which pushes the sliding plate to move synchronously with the L-shaped seats and rack. Since the rack on the sliding plate meshes with the gear on the rotating rod, and the gear meshes with the rack on the other sliding plate, the two sliding plates can drive the L-shaped seats on them to move closer to each other through the transmission of the gear and the two racks, quickly clamping the rock specimen, reducing the cumbersome steps of fixing the specimen, and effectively improving work efficiency.

[0013] 2. After the rock specimen is fixed by the configuration mechanism, the hydraulic push rod two can be activated. It will push the sliding plate two and the measuring piece on it downward. At the same time, the two L-shaped abutments connected to the sliding plate two will also contact the guide roller at one end of the L-shaped rod during the downward movement. With the help of the U-shaped block one, one end of the L-shaped rod will rotate towards the bottom plate, and the other end will cooperate with the sliding rod on the worktable through the slide groove. This allows the worktable to move the clamped rock specimen to below the measuring piece to complete the measurement operation. At the same time, when the worktable moves, it will also compress the spring on the outer wall of the sliding rod two, so that it accumulates energy and provides power for resetting. After the measurement is completed, the hydraulic push rod two can be activated again. It will drive the L-shaped abutment to move upward, thereby releasing the limit on one end of the L-shaped rod. This allows the worktable to move outward under the pushing force of the spring, which facilitates the material loading and unloading operation.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-5 As shown, this utility model is a measuring device for rock test specimens, including a workbench 1, on which a clamping mechanism 2 and a configuration mechanism 3 are provided;

[0025] The clamping mechanism 2 includes two rails 21 fixedly connected to the top of the workbench 1. Two slide plates 22 are slidably connected to the outer surfaces of the two rails 21. L-shaped seats 23 are fixedly connected to the top of each slide plate 22. Rack grooves 24 are provided on each slide plate 22. A fixing block 25 is fixedly connected to the top plate of the workbench 1. A hydraulic push rod 26 is sleeved on the fixing block 25. The output end of the hydraulic push rod 26 is fixedly connected to the corresponding slide plate 22. Racks 27 are fixedly connected to the sides of the two slide plates 22 that are close to each other. The two racks 27 are slidably connected to the two rack grooves 24. A rotating rod 28 is rotatably connected to the top of the workbench 1. A gear 29 is sleeved on the outer wall of the rotating rod 28. The gear 29 meshes with the two racks 27.

[0026] By setting up the clamping mechanism 2, when in use, the rock specimen is placed between the two L-shaped seats 23. Then, the hydraulic push rod 26 is activated, which pushes the sliding plate 22, causing it to move synchronously with the L-shaped seats 23 and the rack 27. Since the rack 27 on the sliding plate 22 meshes with the gear 29 on the rotating rod 28, and the gear 29 meshes with the rack 27 on the other sliding plate 22, the transmission between the gear 29 and the two racks 27 allows the two sliding plates 22 to drive the L-shaped seats 23 on them to move closer to each other, quickly clamping the rock specimen, reducing the tedious steps of fixing the specimen, and effectively improving work efficiency.

[0027] The configuration mechanism 3 includes a base plate 31 located at the bottom of the workbench 1. Two slide rails 32 are fixedly connected to the top of the base plate 31, and the outer surfaces of both slide rails 32 are slidably connected to the workbench 1. A support rod 33 is fixedly connected to the top of the base plate 31, and a fixing block 34 is fixedly connected to the front of the support rod 33. A hydraulic push rod 35 is fitted onto the fixing block 34. Two sliding rods 36 are fixedly connected to the top of the base plate 31, and a sliding plate 37 is slidably connected to the outer wall of the two sliding rods 36. The output end of the hydraulic push rod 35 is fixedly connected to the sliding plate 37. A measuring element 38 is located at the bottom of the sliding plate 37, and two L-shaped abutments 39 are fixedly connected to the bottom of the sliding plate 37. Two U-shaped blocks 310 are fixedly connected to the top of the base plate 31, and L-shaped rods 311 are rotatably connected to each of the two U-shaped blocks 310. One end of each of the two guide rollers 312 is rotatably connected to a guide roller 312. Both guide rollers 312 are in contact with two L-shaped abutments 39. The other end of each of the two L-shaped rods 311 is provided with a sliding groove 313. Sliding rods 314 are fixedly connected to the left and right sides of the worktable 1. The left and right ends of the two sliding rods 314 extend to the outside of the two sliding grooves 313 and are slidably connected to the two sliding grooves 313. A U-shaped block 315 is fixedly connected to the top of the base plate 31. A sliding rod 316 is fixedly connected to the back of the U-shaped block 315. The sliding rod 316 passes through the worktable 1 and is slidably connected to the worktable 1. The rear end of the sliding rod 316 is fixedly connected to a support rod 33. A spring 317 is wound around the outer wall of the sliding rod 316. One end of the spring 317 is fixedly connected to the worktable 1, and the other end of the spring 317 is fixedly connected to the support rod 33.

[0028] After the rock specimen is fixed by the configuration mechanism 3, the hydraulic push rod 35 can be activated. It will push the sliding plate 37 and the measuring piece 38 on it to move downward. At the same time, the two L-shaped abutments 39 connected to the sliding plate 37 will also contact the guide roller 312 at one end of the L-shaped rod 311 during the downward movement. With the help of the U-shaped block 310, one end of the L-shaped rod 311 will rotate towards the bottom plate 31, and the other end will cooperate with the sliding rod 314 on the worktable 1 through the slide groove 313. This allows the worktable 1 to move the clamped rock specimen to below the measuring piece 38 to complete the measurement operation. At the same time, when the worktable 1 moves, it will also compress the spring 317 on the outer wall of the sliding rod 316 to accumulate energy and provide power for resetting. After the measurement is completed, the hydraulic push rod 35 can be activated again. It will drive the L-shaped abutment 39 to move upward, thereby releasing the limit on one end of the L-shaped rod 311. This allows the worktable 1 to move outward under the pushing force of the spring 317, which facilitates the material handling operation.

[0029] A specific application of this embodiment is as follows: In use, the rock specimen is placed between two L-shaped seats 23. Then, the hydraulic push rod 26 is activated, which pushes the sliding plate 22, causing it to move synchronously with the L-shaped seats 23 and the rack 27. Since the rack 27 on the sliding plate 22 meshes with the gear 29 on the rotating rod 28, and the gear 29 meshes with the rack 27 on the other sliding plate 22, the transmission between the gear 29 and the two racks 27 allows the two sliding plates 22 to drive the L-shaped seats 23 on them to move closer to each other, quickly clamping the rock specimen, reducing the tedious steps of fixing the specimen, and effectively improving work efficiency. After the rock specimen is fixed, the hydraulic push rod 35 is activated, which pushes the sliding plate 37 and the measuring piece 38 on it to move downwards. At the same time, the sliding plate 37... The two L-shaped abutments 39 connected to the top will also contact the guide roller 312 at one end of the L-shaped rod 311 during the downward movement. With the help of the U-shaped block 310, one end of the L-shaped rod 311 will rotate towards the bottom plate 31, and the other end will cooperate with the sliding rod 314 on the worktable 1 through the slide groove 313, so that the worktable 1 can move the clamped rock specimen to below the measuring piece 38 to complete the measurement operation. At the same time, when the worktable 1 moves, it will also compress the spring 317 on the outer wall of the sliding rod 316 to accumulate energy and provide power for resetting. After the measurement is completed, the hydraulic push rod 35 can be activated again, which will drive the L-shaped abutment 39 to move upward, thereby releasing the limit on one end of the L-shaped rod 311, so that the worktable 1 can move outward under the pushing force of the spring 317, thus facilitating the material loading and unloading operation.
