Embodiment Construction
[0008] As shown in the figure, the ladder detection device includes an underframe 1, two vertical uprights 2 are arranged on both sides of the middle of the underframe, and several beams 3 are connected between the uprights. Set block 4 to adapt to different specifications of ladders. A wire take-up device 5 is fixed at the rear end of the chassis. The wire take-up device is connected to a section of wire rope 6. The wire rope can be pulled backwards. The wire rope is divided into two sections, and a tension sensor is connected between the two sections. 7. The front wire rope goes around a fixed pulley 8 located in front of the take-up device and is connected with a hook 9 at the front end of the wire rope; the sensing signal of the tension sensor 7 is connected to a tension tester 10.
[0009] The process of using the device of the present invention to test the ladder is:
[0010] According to the specifications of the ladder to be tested 11, select a suitable stopper to locate t...

The invention relates to a ladder detection device used for detecting the mechanical property of a ladder used for electric power overhaul, comprising a chassis both sides of the middle part of which are provided with two vertical stand columns; a plurality of beams are connected between the two stand columns; multi-group baffle plates are longitudinally arranged at the front part of the chassis at intervals; a spooling machine is fixed at the rear end of the chassis, is connected with a section of steel wire rope, and can reel and draw the steel wire rope backwards; the steel wire rope is divided into a front section and a rear section; a tension sensor is connected between the two section of the steel wire ropes; the front section of the steel wire rope is wound on a fixed pulley positioned at the rear part of the chassis and the front end of the front section of the steel wire rope is connected with a hanger; and the sensing signal of the tension sensor is connected with a tension tester. The ladder detection device of the invention has simple structure, can conveniently apply arbitrarily set tension on the pedal beams of the ladder, thus testing the mechanical safety of the ladder accurately, and ensuring the reliability of the use of the ladder.
Description
Technical field [0001] The invention relates to a ladder detection device used to perform mechanical performance detection on ladders for power maintenance. Background technique [0002] Ladder is a commonly used climbing device in electric power construction and maintenance. Unqualified ladders endanger personal safety during use. As for the mechanical properties of ladders, it is usually only possible to observe the appearance based on experience, without a clear judgment. Scientific instruments of bad standards. Although there are currently some ladder mechanical performance testing equipment used for ladder testing, most of them have complex structures, inconvenient operations, high costs, and poor applicability. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a ladder detection device with simple structure, convenient use and accurate detection. [0004] The ladder detection device of the present invention includes a...
