Ladder is the utensil of ascending a height commonly used in power construction, the maintenance, underproof ladder is in use jeopardizing personal safety, whether the mechanical property for ladder is qualified, can only observe outward appearance by rule of thumb usually, lacks a kind of science utensil of clearly judging its fine or not standard.Though also there are some to be used for the ladder mechanical property checkout equipment that ladder detects at present, its most structure is complicated, operation is inconvenient, cost is higher, and applicability is not strong.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of simple in structure, easy to use, accurate ladder testing machine for mechanical properties of detection is provided.
Ladder testing machine for mechanical properties of the present utility model includes a underframe, and both sides, underframe middle part are provided with two vertical columns, are connected with some crossbeams between the column, and the underframe front portion is provided with and can carries out spacing block to the ladder root; The underframe rear end is fixed with a take-up, take-up is connected with one section wire rope, take-up can reel wire rope backward, wire rope is divided into two sections of front and back, be connected with a pulling force sensor between the two sections wire rope in front and back, the leading portion wire rope is walked around one and is positioned at the fixed pulley at underframe rear portion and is connected with a hook at its front end; The transducing signal of described pulling force sensor is connected on the tension tester.
The utility model is simple in structure, can apply the pulling force of any setting easily to the foot-operated beam of ladder, thereby accurate test is made in the mechanics security of ladder, has guaranteed the reliability that ladder uses.

Fig. 2 is a plan structure synoptic diagram of the present utility model.
Embodiment
As shown in the figure, this ladder testing machine for mechanical properties includes a underframe 1, and both sides, underframe middle part are provided with two vertical columns 2, are connected with some crossbeams 3 between the column, and the anterior longitudinal separation of underframe is provided with many group blocks 4, to adapt to the ladder of different size.The underframe rear end is fixed with a take-up 5, take-up is connected with one section wire rope 6, take-up can reel wire rope backward, wire rope is divided into two sections of front and back, be connected with a pulling force sensor 7 between the two sections wire rope in front and back, the leading portion wire rope is walked around one and is positioned at the fixed pulley 8 at underframe rear portion and is connected with a hook 9 at the wire rope front end; The transducing signal of pulling force sensor 7 is connected on the tension tester 10.
Use the process of device to test ladder of the present utility model to be:
Specification according to ladder 11 to be measured, select suitable block that the ladder root is located, ladder top rides on the crossbeam 3 that adapts with its specification, the hook 9 of wire rope front end is hung on the foot-operated beam to be measured on the ladder, operate the reading that take-up 5 reels wire rope and observes tension tester 10 then, reach the value of thrust of setting up to the reading of tension tester, stop take-up, unload after the time that keeps pulling force to continue to set, check each parts of ladder, as it is then qualified for detecting with damage that permanent deformation does not take place.
