Description

Technical Field

[0001] This utility model relates to the field of sample separation technology, and in particular to a triaxial sample separation device. Background Technology

[0002] In triaxial geotechnical tests, the accuracy of specimen preparation directly affects the accuracy of shear strength parameters. Traditional specimen preparation methods have the following drawbacks: 1. Existing technologies rely on manually rotating a cutting disc in conjunction with a wire saw, which is time-consuming and labor-intensive, making it difficult to meet the needs of batch specimen preparation; 2. Manual operation easily leads to geometric deviations in the specimens, especially for specimens with non-standard angles (such as 60°, 90°, and other multi-directional cuts), making it difficult to ensure uniform cutting. Furthermore, existing devices are mostly designed for single cutting angles and cannot adapt to the diverse sample division requirements of different tests. To address these shortcomings, we propose a triaxial specimen division device. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a triaxial sample separation device.

[0004] In order to solve the problems existing in the prior art, the present invention adopts the following technical solution: a triaxial sample dividing device, including a main frame and a mold, wherein the main frame is composed of a counterweight base and a cutting mechanism disposed on the upper surface of the counterweight base; The cutting mechanism includes an assembly plate, multiple assembly slots on the upper surface of the assembly plate, cutting components snapped into the inner wall of the assembly slots, locking nuts threaded onto the surface of the assembly plate, support plates fixedly installed on both sides of the assembly plate, and an electric telescopic rod fixedly installed on the upper surface of the support plate. The cutting component includes multiple cutting blades and assembly blocks that are fixedly installed on one end of the multiple cutting blades and adapted to the assembly groove, and the other ends of the multiple cutting blades are connected to each other. The mold includes a mold cylinder, a cutting guide groove formed on the surface of the mold cylinder for the cutting blade to pass through, and a positioning component located below the mold cylinder.

[0005] Preferably, the telescopic end of the electric telescopic rod is fixedly connected to the upper surface of the counterweight base.

[0006] Preferably, the positioning component includes a positioning disk and a circular protrusion fixedly installed on the upper end of the positioning disk, wherein the outer diameter of the protrusion is adapted to the inner diameter of the mold cylinder.

[0007] Preferably, the lower surface of the positioning disk is fixedly equipped with four positioning pins in a circumferential array, and the upper surface of the counterweight base is provided with positioning grooves that are compatible with the positioning pins.

[0009] Preferably, the guide groove has two sets, and the two sets of guide grooves correspond to two sets of assembly grooves respectively.

[0010] Preferably, the cutting blade is made of 304 stainless steel and has a tungsten carbide wear-resistant layer coated on its surface.

[0011] Preferably, the cutting component has three types, which can cut the sample according to three different requirements.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The locking nut is threaded to the assembly plate, which can be used to press the assembly block in the assembly groove to fix the assembly block. When the locking nut is unscrewed, the assembly groove is exposed.

Combined with the clearance fit between the circular protrusion and the mold cylinder, and the electric telescopic rod driving the cutting blade to complete the cutting, the uniformity of sample cutting can be effectively improved.

Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Please see Figure 1-7 This utility model provides a technical solution: a triaxial sample separation device, including a main frame and a mold.

[0017] The main frame consists of a counterweight base 10 and a cutting mechanism disposed on the upper surface of the counterweight base 10. The cutting mechanism includes an assembly plate 20, multiple assembly slots 21 formed on the upper surface of the assembly plate 20, cutting components snapped into the inner wall of the assembly slots 21, locking nuts 22 threaded onto the surface of the assembly plate 20, support plates 23 fixedly installed on both sides of the assembly plate 20, and an electric telescopic rod 24 fixedly installed on the upper surface of the support plate 23. The telescopic end of the electric telescopic rod 24 is fixedly connected to the upper surface of the counterweight base 10, and a control button for controlling the start and stop of the electric telescopic rod 24 is provided on the surface of the counterweight base 10.

[0018] The cutting component includes multiple cutting blades 30 and assembly blocks 31 that are fixedly installed on one end of the multiple cutting blades 30 and adapted to the assembly groove 21. The other ends of the multiple cutting blades 30 are connected to each other. There are two sets of assembly grooves 21. One set is distributed at equal angles of 60° and there are 6 of them. The other set is distributed at equal angles of 90° and there are 4 of them. The groove body of the assembly groove 21 has a T-shaped structure. The cutting blades 30 are fixed by tightening the locking nut 22.

[0019] Select the appropriate cutting component according to the test requirements, dividing the sample into six equal parts at 60° or four equal parts at 90°. Insert the assembly block 31 into the corresponding T-shaped assembly groove 21 of the assembly plate 20. Use the locking nut 22 to connect with the assembly plate 20 by thread. The locking nut 22 can press the assembly block 31 in the assembly groove 21 to fix the assembly block 31. When the locking nut 22 is unscrewed, the assembly groove 21 is exposed. By using two sets of switchable assembly grooves 21 (6 grooves at 60° distribution / 4 grooves at 90° distribution / 3 grooves at 120° distribution) with the T-shaped assembly block 31, the sample cutting requirements of different test standards can be met.

[0020] The mold includes a mold cylinder 40, a cutting guide groove 41 formed on the surface of the mold cylinder 40 for the cutting blade 30 to pass through, and a positioning component set below the mold cylinder 40. There are two sets of guide grooves 41, and the two sets of guide grooves 41 correspond to two sets of assembly grooves 21 respectively. The positioning component includes a positioning plate 50 and a circular protrusion 51 fixedly installed on the upper end of the positioning plate 50. The outer diameter of the protrusion 51 is adapted to the inner diameter of the mold cylinder 40. Four positioning pins 52 are fixedly installed in a circumferential array on the lower surface of the positioning plate 50. The upper surface of the counterweight base 10 is provided with a positioning groove 53 adapted to the positioning pins 52. The positioning plate 50 is embedded into the positioning groove 53 of the counterweight base 10 by the four positioning pins 52 at the bottom to achieve precise centering. Then the mold cylinder 40 is fitted onto the circular protrusion 51 of the positioning plate 50, and axial fixation is completed by a clearance fit of ±0.05mm to ensure that the sample has no risk of displacement during the cutting process.

[0021] When the electric telescopic rod 24 is powered on, it retracts downwards, and the traction support plate 23 and assembly plate 20 are pressed down as a whole. Multiple cutting blades 30 move synchronously under the constraint of the guide groove 41 to complete the sample cutting. There is no manual intervention in the cutting process, which can effectively improve the uniformity of sample cutting.

[0022] Specifically, the working principle and operation method of this utility model are as follows: Mold installation: Align the four positioning pins 52 of the positioning plate 50 with the positioning grooves 53 of the counterweight base 10 and insert them vertically to ensure no shaking. Then, fit the mold cylinder 40 into the circular protrusion 51 of the positioning plate 50, and then place the pattern inside the mold cylinder 40.

[0023] Cutting mode selection 60° six-equal division cutting: Select 6 sets of T-shaped assembly slots 21, and insert the corresponding assembly blocks 31 and steel ropes; 90° quadrature cutting: Switch to assembly slot 21 (4th group) and repeat the assembly process; 120° three-part cutting: Switch to assembly slot 21 (group 3) and repeat the assembly process.

[0024] Steel rope fixing: Tighten the locking nut 22 to ensure that the assembly block 31 is not displaced in the T-slot.

[0025] Automatic cutting: Press the control button to start the electric telescopic rod 24, observe the cutting blade 30 moving at a constant speed along the guide groove 41, and take out the sample after cutting is completed.
