Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.
As shown in fig. 1-2, the utility model discloses an automatic lift ladder tester, including control cabinet 1 and test bench, the test bench includes 3 racks of ladder, four pulleys 22, tension measuring device 23, stay cord 24, tension device 25 and guide rail 26, and tension measuring device 23 is force sensor, and tension device 25 is electronic hydraulic rod. One end of the pull rope 24 is connected with the movable part of the electric hydraulic push rod, the other end is connected with a tension sensor, and the tension sensor is connected with the pedal of the ladder 3 through a connecting piece formed by combining a chain 27 and a drag hook 28. The draw hook 28 hooks different links of the chain 27 to adjust the effective length of the chain 27. The intermediate section of the pull cord 24 is guided by four pulleys 22. The pulley 22 closest to the tension sensor is slidably arranged on the guide rail 26 and can be locked on the guide rail 26 by screws, and the guide rail 26 is arranged close to the bottom surface. The tension sensor and the electric hydraulic push rod are electrically connected with the control console 1, the tension sensor transmits a measured tension value to the control console 1, and the control console 1 controls the electric hydraulic push rod to operate according to the measured tension value, so that the tension output value of the electric hydraulic push rod is effectively controlled.
