Product name: Microcomputer-controlled bridge expansion device test machine
Product model: JK-SSF-50
Product function:
It is used for the clamping performance test of modular expansion devices in the field of bridge expansion devices, the test of the holding force between rubber and steel in the expansion joint sealing device, and the assembly tolerance and waterproof performance test. This machine has the functions of compression and stretching of bridge expansion devices. It is equipped with different clamping tools, which can push and pull the expansion device horizontally, simulate the actual stress state of the expansion device on the highway bridge, and can be used for the assembly tolerance and waterproof performance test of samples such as single-slit modular, double-slit and more multi-slit modular, comb-tooth plate expansion devices. The product is widely used in domestic quality inspection units, scientific research institutes, highway and water transport inspection agency laboratories, etc.
Based on the standard: JT/T 327 General Technical Conditions for Highway Bridge Expansion Joint Devices
It adopts a dual independent loading split structure and is equipped with a large-stroke screw loading mechanism. The test loading is stable and the test space is saved. By replacing the sensor, the expansion joint clamping performance test, assembly tolerance and waterproof performance test can be carried out at the same time. The loading system is controlled by a servo motor to ensure low noise, fast response and high stability of the system. The equipment is light in weight and equipped with a rolling mechanism for easy storage in the laboratory. The computer human-machine interface and the independently developed embedded measurement and control software have the characteristics of compact structure and easy operation. The load, strength, speed and loading process curves are automatically displayed, and the sample is automatically judged to be broken and the test results are calculated and saved.
