Tension tester for ladder

Abstract

The invention discloses a tension tester for a ladder. The tension tester comprises a rack, a hydraulic station and a tension mete. The tension tester is characterized in that vertical stand columns are fixedly arranged at the two sides of the rack; a pair of bearing seats capable of sliding up and down are arranged on the vertical stand columns; a moving frame is arranged between the bearing seats; a motor seat is arranged at the outer side of one bearing seat; a motor base is provided with a motor, and a driving rod is arranged on the bearing seat in a penetrating manner; one end of the driving rod is in transmission connection with the motor; a hydraulic cylinder is fixedly arranged in the middle of the rack and connected with the hydraulic station, and a sliding rod is fixedly arrangedat the bottom of the rack; a movable idler wheel base is arranged on the sliding rod, and idler wheels are arranged on the idler wheel base. The tension tester is used for testing the tension of a foot rest lever of the ladder, so that the use safety of the ladder is guaranteed; the tension tester is simple in structure, convenient to test and low in cost.

Description

technical field [0001] The invention relates to the technical field of tensile testing equipment, in particular to a tensile testing machine for ladders. Background technique [0002] Ladders are high-level equipment often used in the construction or maintenance of electric power, construction and other fields. They are also often used to pick and place items at high levels in daily life. Unqualified ladders will pose a great threat to personal safety during use. Therefore, It is very necessary to test the mechanical performance of the ladder during its production and manufacture. Most of the existing ladder mechanical testing equipment has complex structure, inconvenient operation and high cost. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a tensile testing machine for ladders, which solves the problems raised in the background art above. [0004] To achieve the above object, the present invention is achie...
