Description

Technical Field

[0001] This utility model relates to a dual hydraulic power compression-shear testing machine, belonging to the technical field of compression-shear testing machines. Background Technology

[0002] The compression-shear testing machine is mainly used for testing the axial and radial compressive, shear, and rotational mechanical properties of various bridge plate and pot bearings under combined compressive and shear forces. It can perform tests on the compressive elastic modulus, shear elastic modulus, allowable shear angle, coefficient of friction, and ultimate compressive strength of the rubber bearings.

[0003] Chinese Patent Publication No. (CN 216284693 U) discloses a compression-shear testing machine, including a base. A connecting plate is fixedly connected to one side of the top wall of the base, and an mounting plate is fixedly connected to the top wall of the connecting plate. A reinforcing block, a computer, a cylinder, and a telescopic rod are sequentially fixedly connected to the bottom wall of the mounting plate from one side to the other. A compression-shear mechanism is arranged below the cylinder, and a connecting mechanism is arranged below the telescopic rod. This utility model, through the setting of a well-designed compression-shear head mechanism, allows for quick installation and disassembly of the compression-shear head mechanism, facilitating its maintenance. It also features an efficient compression-shear test control and analysis mechanism, enabling convenient and efficient compression-shear testing. Furthermore, it incorporates a well-designed compression-shear test lifting and stabilization mechanism, ensuring good stability during actual compression-shear lifting operations.

[0004] Compression and shear testing machines typically use a sample carriage to place the sample vertically on the pressure plate. To ensure the passage of the sample carriage, the compression and shear testing machine is usually open on the left and right sides or front and back sides. Therefore, when the pressure plate presses down on the sample for testing, the sample may break due to the squeezing force. At this time, the broken sample may splash outward due to the squeezing force, and the splashed sample fragments may pose a danger to the testing personnel, making the safety of the testing personnel low.

[0005] To address this, a dual hydraulic dynamic compression-shear testing machine is proposed. Utility Model Content

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-5As shown, this utility model embodiment provides a dual hydraulic power compression-shear testing machine, including a compression-shear testing machine body 1. A base plate 3 is fixedly installed at the bottom of the compression-shear testing machine body 1. A mounting frame 4 is fixedly installed on the right side of the top of the base plate 3. A sample delivery trolley 5 is provided on the top of the mounting frame 4. The left side of the sample delivery trolley 5 holds a test sample 6. The test sample 6 is located in the inner cavity of the compression-shear testing machine body 1. A protective mechanism 2 is provided on the surface of the compression-shear testing machine body 1. The protective mechanism 2 includes a drive motor 201, a screw block 203, and a first baffle 207. The second baffle 208 and the two drive motors 201 are located on the top of the compression-shear testing machine body 1. The four screw blocks 203 are located on the front and rear sides of the compression-shear testing machine body 1. The outer sides of the four screw blocks 203 are movably connected to the transmission rods 204. The other ends of the four transmission rods 204 are movably connected to the moving frames 205. The outer sides of the two moving frames 205 are fixedly connected to the connecting rods 206. The two first baffles 207 are located on the left side of the compression-shear testing machine body 1, and the two second baffles 208 are located on the right side of the compression-shear testing machine body 1. The inner sides of the first baffle 207 and the two second baffles 208 are fixedly connected to the other ends of the four connecting rods 206. The two drive motors 201 are fixedly installed on the front and rear sides of the top of the compression-shear testing machine body 1. The output ends of the two drive motors 201 are fixedly connected to bidirectional screws 202. The four screw blocks 203 are threaded to the upper and lower sides of the surface of the two bidirectional screws 202. The surfaces of the two second baffles 208 are provided with slots 209. The left side of the sample delivery trolley 5 penetrates the inner cavity of the two second baffles 208 and extends to the compression-shear test machine. Inside the inner cavity of the test machine body 1, guide rods 210 are fixedly installed on both the front and rear sides of the compression-shear test machine body 1. Two movable frames 205 are slidably connected to the surfaces of the four guide rods 210. Movable grooves 211 are opened on both the front and rear sides of the top of the bottom plate 3. The bottoms of the two first baffles 207 and the two second baffles 208 are slidably connected to the inner cavities of the two movable grooves 211. Limiting grooves 212 are opened on both the front and rear sides of the compression-shear test machine body 1. The inner sides of the four screw blocks 203 are slidably connected to the inner cavities of the four limiting grooves 212.

[0030] By setting up the protective mechanism 2, the output of the drive motor 201 causes the moving frame 205 to move the second baffle 208 and the first baffle 207 inward or outward. By adjusting the position of the second baffle 208 and the first baffle 207, the inner cavity of the compression-shear testing machine body 1 can be sealed. When the compression-shear testing machine body 1 tests the test sample 6, it can prevent the test sample 6 from breaking due to the pressure and splashing out of the inner cavity of the compression-shear testing machine body 1, ensuring the safety of the testing personnel when testing the test sample 6 and facilitating the operation. By setting the slot 209, the sample delivery trolley 5 can be extended into the inner cavity of the compression-shear testing machine body 1. To prevent the second baffle 208 from obstructing the sample delivery of the sample delivery trolley 5, a guide rod 210 is provided to limit the movement of the moving frame 205, preventing the moving frame 205 from deviating in direction and affecting the adjustment of the positions of the first baffle 207 and the second baffle 208. A moving groove 211 is provided to limit the movement of the first baffle 207, preventing the first baffle 207 and the second baffle 208 from deviating during movement and affecting the sealing of the inner cavity of the compression shear testing machine body 1. A limiting groove 212 is provided to limit the movement of the screw block 203, preventing the screw block 203 from rotating synchronously with the bidirectional screw 202.

[0031] Example 2

[0032] In one embodiment, the mounting bracket 4 has sliding grooves 7 on both the front and rear sides of the top, the sample delivery trolley 5 is slidably connected to the inner cavity of the two sliding grooves 7 on both the front and rear sides of the bottom, and the base plate 3 has anchor bolts 8 threadedly connected to the left and right sides of the top, and the bottom of the four anchor bolts 8 is threadedly connected to the ground.

[0033] By setting the slide 7, the movement direction of the sample delivery trolley 5 can be limited to prevent it from deviating during movement, which would affect the delivery of the test sample 6. By setting the anchor bolts 8, the overall equipment can be stabilized to prevent the equipment from shaking due to accidental collisions caused by external factors.

[0034] In operation, this invention first moves the sample 6 to the inner cavity of the compression-shear testing machine body 1 via the sample delivery trolley 5. Then, through the output of the drive motor 201, the bidirectional screw 202 rotates, causing the screw block 203 to move outward along the surface of the bidirectional screw 202. The transmission rod 204 swings due to the movement of the bidirectional screw 202, driving the moving frame 205 to move inward. The moving frame 205 drives the connecting rod 206 to move inward. At this time, the first baffle 207 and the second baffle 208 both move inward, sealing the inner cavity of the compression-shear testing machine body 1. Then, the compression test is performed by the compression-shear testing machine body 1. When the sample 6 breaks and splashes, the first baffle 207 and the second baffle 208 can shield the broken fragments.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
