Problems solved by technology
This requires testing the dynamic balance of the manufactured flat elevator cables. In addition, since the cables are frequently bent up and down with the car, the cable insulation sheath may be broken, the wire core may be broken, and short circuits and signal interruptions may occur. , therefore, it is necessary to test the tensile strength of flat elevator cables

The invention discloses a multi-core ultra high-speed flat type elevator cable testing device in the technical field of cable testing equipment. The device comprises a machine body, wherein the top ofthe machine body is fixedly provided with a driving air cylinder; the right side output shaft of the driving air cylinder is connected with one end of a cable through a stationary fixture; a tensionsensor is fixedly installed on the inner cavity wall of a detection device; the top of the machine body is also fixedly provided with an installation frame; the top rod of the installation frame is sheathed with a line winding wheel; a connection line wound on the line winding wheel is connected with the cable; the left side and the right side of the line winding wheel are symmetrically provided with two groups of sliding rods; and the bottom of each sliding rod is provided with a measurement clamping jaw. By use of the device, after two ends of a cable to be detected are fixed through the stationary fixture and a fixing block, the air cylinder is started to stretch the cable, and the tensile strength of the cable is obtained. The device can carry out measurement detection by aiming at thetensile strength and the anti-bending degree of the cable, and has the advantages of being high in practical value and convenient in measurement detection.
Description
technical field [0001] The invention discloses a multi-core ultra-high-speed flat elevator cable test device, in particular to the technical field of cable test equipment. Background technique [0002] Super-high-rise super-high-speed elevators usually use large cars. Therefore, it is required that the U-shaped bending diameter of the accompanying ultra-multi-core flat elevator cables must meet the design specifications. The general elevator installation shaft is relatively narrow. In the hoistway space, the flat elevator cable that hangs vertically freely and moves up and down with the elevator car at high speed must ensure a high degree of dynamic balance performance, and the cable is placed before and after the operation. The left and right swings beyond the range, and the cables caused by rubbing the shaft wall or the elevator car are damaged. This requires testing the dynamic balance of the manufactured flat elevator cables. In addition, since the cables are frequently...
