Description

Technical Field

[0001] This utility model relates to the field of testing the bearing capacity of the borehole wall of steel components, specifically a testing device for the bearing capacity of the borehole wall of angle steel components of Q550 high-strength steel transmission towers. Background Technology

[0002] The main characteristics of Q550 high-strength steel include high strength, good toughness, corrosion resistance, low-temperature impact toughness, and good weldability. Q550 high-strength steel has good toughness, maintaining good deformation capacity under external force and is not easily broken. Specially treated Q550 high-strength steel has good weather resistance and can resist corrosion to a certain extent. Q550 high-strength steel can maintain good impact energy absorption at relatively low temperatures, making it suitable for use in cold regions and low-temperature environments.

[0003] Some angle steel components of transmission towers are made of Q550 high-strength steel, which requires specialized equipment to test the pressure bearing capacity of the hole walls of the angle steel components. Therefore, we have proposed a test equipment for the pressure bearing capacity of the hole walls of Q550 high-strength steel transmission tower angle steel components. Utility Model Content

[0004] The purpose of this invention is to provide a testing device for the bearing capacity of the borehole wall of the angle steel component of Q550 high-strength steel transmission tower, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A test device for the bearing capacity of borehole walls of Q550 high-strength steel transmission tower angle steel components includes a workbench, a test bench, fixed blocks, threaded holes, a screw, a turntable, mounting holes, fixing holes, bearings, and clamping rings. The test bench is fixedly mounted on the top of the workbench. Fixed blocks are fixedly mounted at both ends of the top of the workbench. A threaded hole is formed on one side of each fixed block, through which a screw is rotatably connected. A turntable is fixedly mounted on the end of the screw furthest from the fixed blocks. A mounting hole is formed at the center of one side of the turntable, and one end of the screw is fixedly mounted inside the mounting hole. Several fixing holes are formed on one side of the turntable. A bearing is rotatably connected to one end of the screw, and a clamping ring is fixedly mounted on one side of the bearing.

[0007] Preferably, there are two clamping rings, and the two clamping rings are symmetrical about the center of the test platform.

[0008] The above method uses clamping rings to clamp and fix the angle steel component placed on top of the test bench.

[0009] Preferably, the top two ends of the workbench are fixedly provided with support plates, and the top of the support plates is fixedly provided with a horizontal plate.

[0010] The above solution allows the horizontal plate to be fixed to the top of the support plate by setting up a support plate.

[0011] Preferably, an observation hole is provided at the top of the horizontal plate, and a hydraulic cylinder is fixedly installed through the top of the horizontal plate.

[0012] The above scheme, by setting up an observation hole, facilitates the observation of the test status of the test bench.

[0013] Preferably, a test block is fixedly installed at the bottom of the hydraulic cylinder, and a telescopic rod is installed on one side of the workbench.

[0014] The above solution allows the lever and pin to extend and retract by setting up a telescopic rod.

[0015] Preferably, a lever is fixedly provided on one side of the telescopic rod, and a pin is fixedly provided on one side of the lever.

[0016] The above solution uses a pin that is inserted into a fixing hole to limit the turntable and prevent it from rotating.

[0017] Preferably, the pin and the fixing hole are matched, a push rod is fixedly provided at the bottom of the worktable, an electric push rod is movably provided at the bottom of the push rod, and a support foot is fixedly provided at the bottom of the electric push rod.

[0018] The above solution, by setting an electric push rod, allows the push rod to extend and retract, thereby adjusting the height and level of the equipment. The addition of support feet further improves the stability of the device.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. The test equipment for the bearing capacity of the borehole wall of the angle steel component of the Q550 high-strength steel transmission tower is used by first placing the angle steel component on the top of the test platform, then moving the lever to disengage the pin from the fixing hole. By rotating the turntable, the screw rotates. Under the combined action of the bearing, clamping ring and screw, the clamping ring firmly fixes the angle steel component to be tested. Then, the lever is released, and the pin returns to its original position to limit the turntable. The above design ensures that the angle steel component will not shake during the test, thus improving the stability of the device.

[0021] 2. The Q550 high-strength steel transmission tower angle steel component hole wall pressure bearing performance testing equipment uses the extension and retraction of the hydraulic cylinder at the top of the horizontal plate to make the test block at the bottom of the hydraulic cylinder test the pressure bearing performance of the angle steel component hole wall, and observe whether the angle steel component deforms during the test to check its quality, thereby achieving the test purpose. At the same time, the electric push rod is set so that the push rod can be extended and retracted, thereby adjusting the height and level of the equipment. Attached Figure Description
