Description

Technical Field

[0001] This application relates to the field of load testing, and particularly to a static mechanical load testing machine. Background Art

[0002] A static mechanical load testing machine is a device used to test the performance and endurance of materials or structures under static loads. They are commonly used in the engineering field and materials science research. These testing machines can apply a stable static load or pressure to the material or structure being tested and measure parameters such as their deformation, stress, strain, and load-bearing capacity.

[0003] Currently, when a static mechanical load testing machine is in actual use, it cannot be adapted to test pieces of different specifications. When the specifications and dimensions of the test pieces are inconsistent, it is necessary to replace the loads of different specifications for testing. Otherwise, it is easy to cause the problem of uneven distribution of the load on the surface of the test piece, and the direct contact between the load and the test piece is likely to cause wear of the load, resulting in inaccurate quality and affecting the authenticity and accuracy of the test data. It is also easy to cause damage to the test piece. Utility Model Content

[0012] By adopting the above technical solution, it is convenient to unlock the hook through the top connecting ring, making the structure more flexible.

[0013] Preferably, a top connecting block is fixedly connected to the bottom of the top connecting ring. A load-bearing member is fixedly connected to the bottom of the top connecting block, and a bottom connecting block is fixedly connected to the bottom of the load-bearing member.

[0014] By adopting the above technical solution, the hook is always vertically downward through the load-bearing member and will not tilt during movement.

[0015] Preferably, a bottom connecting ring is fixedly connected to the bottom of the bottom connecting block. A strap connecting block is fixedly connected to the bottom of the bottom connecting ring, and a connecting strap is fixedly connected to the side wall of the strap connecting block.

[0019] Preferably, a load-bearing frame is fixedly connected to the bottom of the fixing member. A fixing plate is fixedly connected to the top of the load-bearing frame, and a cross bar movably penetrates through the side wall of the fixing plate.

[0020] By adopting the above technical solution, the fixing plate provides vertical support for the internal load.

[0021] Preferably, a support column is fixedly connected to the bottom of the load-bearing frame, and a suction cup is fixedly connected to the bottom of the support column.

[0024] 1. Use the hook to vertically pull the top connecting ring to move vertically, thereby driving the strap connecting block to move vertically upward, causing the connecting belt to drive the entire load frame to move vertically in a horizontal state. Subsequently, the frequency conversion drive control motor suspends the load frame at the top of the test component through horizontal movement, and then places the load frame downward through the hook, so that the bottom of the load frame is evenly attached to the top surface of the test component. Thus, when the test component undergoes dimensional changes, there is no need to replace the load, and the load can still act evenly on the surface of the test component, thereby conducting a static load test. Moreover, the load bag avoids direct contact between the load and the test component, thus preventing damage to the surface of the test component. Description of the Drawings

[0039] With the above settings, the staff member pushes the bracket 1, driving the runner 11 to rotate, so that the I-beam 12 is located above the test component 4 in the component mounting rack 3, facilitating the subsequent load test.

[0040] Referring to Figure 3, 4, 5, The horizontal lifting load mechanism 2 includes a cross bar 218. The outer wall of the cross bar 218 horizontally penetrates through the side wall of the collar 219, so that the collar 219 is slidably connected to the cross bar 218. The bottom of the collar 219 is fixedly connected to one side of the load bag 220 close to the collar 219, so that the load bag 220 is fixed through the collar 219. A horizontal zipper is provided at the top of the load bag 220, and the horizontal zipper is located directly below the cross bar 218. When the load needs to be placed, the zipper is horizontally opened to place the load inside the load bag 220, which is convenient for placing different loads, such as lead shots, sand, bricks, etc. The load bag 220 has a weight limit of ten kilograms, and each load bag 220 should be loaded with an equal weight to ensure the loading uniformity in the experiment. The horizontal lifting load mechanism 2 also includes a traction rope 21 fixedly connected to the bottom of the variable-frequency drive control motor 13. An annular groove is provided on the side wall of the turntable 22, and the bottom of the traction rope 21 fits into the annular groove provided on the side wall of the turntable 22, so that the turntable 22 can be driven to move when the traction rope 21 contracts.

One end of the hook 25 away from the sleeve column 24 is sleeved with the inner wall of the top connection ring 26, which is convenient for unlocking when placing the load. One side of the top connection ring 26 away from the hook 25 is fixedly connected to the top of the top connection block 27. One end of the top connection block 27 away from the top connection ring 26 is fixedly connected to the top of the load-bearing member 28, so that a vertically downward pulling force is brought to the hook 25 through the load-bearing member 28.

[0041] With the above settings, the staff places the load inside the load bag 220, and then the staff starts the variable-frequency drive control motor 13 through the console 5. The variable-frequency drive control motor 13 first drives the traction rope 21 to contract upward. While the traction rope 21 contracts upward, it will drive the turntable 22 to move vertically upward. The turntable 22 will drive the connecting piece 23 to move vertically upward. The connecting piece 23 will drive the sleeve column 24 to move vertically upward. The sleeve column 24 will drive the hook 25 to move vertically upward. The hook 25 will drive the load-bearing member 28 to move vertically upward through the top connection block 27. The load-bearing member 28 will drive the bottom connection ring 210 to move vertically upward through the bottom connection block 29.

[0042] Refer to Figure 6, one end of the side wall of the strap connection block 211 close to the strap connection block 211 is fixedly connected to one end of the connection strap 212 close to the strap connection block 211, so as to facilitate driving the mechanism to lift through the connection strap 212. One end of the connection strap 212 far from the strap connection block 211 is fixedly connected to one end of the connecting rod 213 close to the connection strap 212. One end of the connecting rod 213 far from the connection strap 212 is fixedly connected to the side wall of the rotating disc 214. A circular through-hole is opened on the outer wall of the fixing member 215, and the rotating disc 214 movably penetrates through the circular through-hole opened on the outer wall of the fixing member 215, so that the rotating disc 214 is rotatably connected to the fixing member 215. The bottom of the fixing member 215 is fixedly connected to the top of the load frame 216, so as to drive the load frame 216 to be vertically lifted. The top of the load frame 216 is fixedly connected to the bottom of the fixing plate 217. A through circular through-hole is opened on the side wall of the fixing plate 217, and the cross bar 218 movably penetrates through the through circular through-hole opened on the side wall of the fixing plate 217, so that the cross bar 218 is slidably connected to the fixing plate 217. The bottom of the load frame 216 is fixedly connected to one end of the support column 221 close to the load frame 216. The bottom of the support column 221 is fixedly connected to the top of the suction cup 222, so as to provide vertical support for the structure and make the overall structure more stable.

[0043] Through the above settings, when the bottom connection ring 210 moves vertically upward, the bottom connection ring 210 will drive the strap connection block 211 to move upward. The strap connection block 211 will pull the connection strap 212, the connection strap 212 will pull the connecting rod 213, and the connecting rod 213 will drive the rotating disc 214 to rotate, so that the connecting rod 213 is in a vertical state.

Subsequently, under the control of the console 5, the frequency conversion drive control motor 13 will move horizontally, so as to drive the load frame 216 to hang above the component loading rack 3. Subsequently, the frequency conversion drive control motor 13 will release the towing rope 21, so as to drive the overall load frame 216 to move vertically downward, so that the bottom of the load bag 220 is attached to the top of the test component 4, so as to conduct a static load test on the test component 4 through the load inside the load bag 220.

[0044] Among them, the frequency conversion drive control motor 13, the console 5, and the test component 4 are all prior arts, and their structural principles will not be elaborated here. There are also components such as switches and sensors, which will not be elaborated here because they are not the main technical points.

[0046] Drive the turntable 22 to move vertically upward through the towing rope 21, thereby driving the load frame 216 to move upward, so that the overall structure moves vertically upward. With the horizontal movement of the variable-frequency drive control motor 13, the load frame 216 will be suspended to the top of the component carrier 3, and then drive the load frame 216 to move vertically downward through the variable-frequency drive control motor 13, so that the load bag 220 superimposes loads on the top of the test component 4, thereby performing a static load test.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
