The day for announcing is on May 12nd, 2010; Notification number is that the Chinese patent of CN201464299U discloses a kind of parts fracture strength test device; It is made up of control system, lifting jack, load transducer, stand and anchor clamps; Load transducer and lifting jack are installed on the level table of stand from top to bottom successively, and anchor clamps are installed on the side of stand, and load transducer is electrically connected with control system.Its weak point is to accomplish towing hook and connects the destructive test of plate, and this device adopts the mode of compression that parts are ruptured, and the strength test of towing hook and web joint thereof need be carried out forward and 30 ° of both directions are done stretching experiment to towing hook.
The utility model content
The purpose of the utility model is the deficiency that the destructive test device that overcomes prior art can't carry out breaking test to towing hook, and the intensity experiment device of a kind of towing hook and web joint thereof is provided, and this experimental provision is simple and compact for structure, and functional reliability is high; Cost of manufacture easy to process is lower; Can carry out forward and 30 ° of angle load tests.
To achieve these goals; The utility model adopts following technical scheme: the intensity experiment device of a kind of towing hook and web joint thereof, comprise drawing machine, base, adjusting bearing, hold-down support and cover plate, and said drawing machine comprises the levelling bench of two root posts, crossbeam and bottom; The crossbeam liftable; Base comprises leveling board and two vertical plates that are positioned on the same perpendicular, and base is fixed on the levelling bench of drawing machine, regulates bearing and is fixedly connected with two vertical plates of base; Regulate support and cover plate and form a box body, hold-down support is positioned at box body inside.Drawing machine is the door type structure; Height through the Electric Machine Control crossbeam stretch towing hook and web joint thereof; Hook and web joint thereof are fixed in the box body of regulating support, cover plate and hold-down support composition, and whole box body is fixed on the levelling bench of drawing machine through base.The hook end of towing hook and web joint thereof is connected with the crossbeam of drawing machine through wire rope, and height to the towing hook through control stretching machine crossbeam destroys, and the measurement maximum stretching force reaches the loading experiment purpose.
As preferably, the levelling bench of drawing machine is provided with many longitudinal flutings, and the correspondence position of base is provided with the location and wears groove.The setting of groove can be moved base on platform.
As preferably, two groups of threaded holes that are connected with base are arranged around the said adjusting bearing.Select different threaded holes can make towing hook and levelling bench form different angles, cooperate with the position of base on the drawing machine levelling bench simultaneously, satisfy the requirement of loading experiment different test angle.
As preferably, said hold-down support is processed by ABS plastic, and upper surface and towing hook and web joint thereof agree with.ABS plastic has toughness, and the good mechanical property that hardness, rigidity are balanced is not mutually become flexible when with agreeing with of towing hook and web joint thereof towing hook being stretched, and makes stability under loading.
The beneficial effect of the utility model is: (1) is simple and compact for structure, and functional reliability is high; (2) cost of manufacture easy to process is lower; (3) can carry out forward and 30 ° of angle load tests.
