Description
Technical field
The present invention relates to a kind of pick-up unit, particularly a kind of machines that is used to detect trundle brake sheet fatigue strength.
Background technology
Among the international standard ISO22883-2004; The conveying arrangement of speed below 1.1 meter per seconds (4 kilometers/hour) proposed " fatigue detecting of brake and locking device " with castor and wheel; Be defined in per minute circulation 10 times; Detect altogether under the situation of circulation 5000 times, if its brake does not produce any wearing and tearing or continuous deformation to the dysfunction influence with locking device, detection is both for passing through.With European castor standard EN 12530, EN 12532, and such regulation is all arranged among the EN 12533 among the ISO 22884-2004.And the castor of domestic production does not have the test through this project, also not to its machines that detects, so the brake gear of castor to be whether brake block meets safety standard just unknown, for its use brings potential safety hazard.
Summary of the invention
The present invention provides a kind of fatigue strength detecting machine of trundle brake sheet, and purpose is to solve the prior art problem, and providing a kind of can detect trundle brake sheet fatigue strength, to guarantee the satisfactory brake block machines of trundle brake sheet.
The present invention's technical scheme that adopts of dealing with problems is:
Fatigue strength detecting machine of trundle brake sheet has frame, and the frame lower end laterally is provided with motor, and motor is connected with electronic counter, and electronic counter is connected with inductive switch; The output shaft of motor links together with reducing gear; An end of rocking bar is connected with reducing gear in the crank and rocker mechanism, and the rotating shaft that the other end is located on its top is connected, and the other end of rotating shaft then is connected with the brake block driving mechanism; Said brake block driving mechanism: have actuating arm and castor fixed mechanism; Actuating arm is fixed in the rotating shaft through flat key; Have the groove that can the brake lever front end of castor be blocked on the actuating arm, this groove is positioned at rotating shaft one side, and the axial direction of this groove is parallel to rotating shaft; The castor fixed mechanism is installed in frame rotating shaft one side, and is positioned at a corresponding side of actuating arm groove.
Said actuating arm comprises a straight-arm, upward driving chip reaches driving chip down, and this straight-arm one end is fixed in the rotating shaft through flat key, and driving chip is fixed on the other end of straight-arm up and down, and forms the groove that can the brake lever front end of castor be blocked between the driving chip up and down.
Beneficial effect of the present invention: can detect trundle brake sheet fatigue strength, meet the requirements, improve the security of using to guarantee trundle brake sheet.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is described further.
Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, fatigue strength detecting machine of trundle brake sheet has frame, and the frame lower end laterally is provided with motor 1, and motor 1 is connected with the electronic counter (not shown), and electronic counter is connected with the inductive switch (not shown).The output shaft of motor 1 links together with reducing gear 2.An end of rocking bar is connected with reducing gear 2 in the crank and rocker mechanism 3, and the rotating shaft 4 that the other end is located on its top is connected, and the other end of rotating shaft 4 then is connected with brake block driving mechanism 5.Said brake block driving mechanism 5: have actuating arm 8 and castor fixed mechanism 6; Actuating arm 8 is fixed in the rotating shaft 4 through flat key; Actuating arm 8 comprises a straight-arm 81, go up driving chip 82 and driving chip 83 down; These straight-arm 81 1 ends are fixed in the rotating shaft 4 through flat key, and driving chip 82,83 is fixed on the other end of straight-arm 81 up and down, wherein go up driving chip 82 and are fixed on the straight-arm 81 through securing member; Following driving chip 83 is fixed on the driving chip 82 through securing member, and up and down driving chip 82, form the groove 80 that can brake lever 10 front ends of castor be blocked between 83.
Said actuating arm is not limited to the structure of being mentioned in the present embodiment, and any analog structure all falls into scope of the present invention.
The trundle bracket 7 that will install brake block 9 during detection earlier is fixed on the castor fixed mechanism 6, and the brake lever 10 of its trundle bracket 7 inserts rotating shaft 4, and the front end of brake lever 10 inserts in the groove 80 of actuating arm 8, starter motor 1.At this moment; Motor 1 is kept to per minute 10 through reducing gear 2 with rotating speed to be changeed, and converts rotation into swing through driving crank and rocker mechanism 3, again through rotating shaft 4; The swing of per minute 10 times is delivered on the brake block driving mechanism 5, and actuating arm 8 is swung with the swing of rotating shaft 4.Because trundle bracket 7 is fixed on the castor fixed mechanism 6; Support 7 bodies are not swung; And brake lever 10 front ends insert in the groove 80 of actuating arm 8, and brake lever 10 is swung along with the swing of actuating arm 8, so the brake block 9 of drive installation on trundle bracket 7 simulated the action of brake.Note action frequency through inductive switch and electronic counter; During to 5000 times, send the signal that motor 1 is stopped operating, after stopping operating; Take off the brake block 9 that is installed on the trundle bracket 7 and detect preceding brake block and contrast to see whether bigger distortion or wearing and tearing have taken place.As being out of shape or wearing and tearing in the margin tolerance of standard code, then trundle brake sheet fatigue strength detects and passes through.Exceeded the margin tolerance of standard code like distortion or wearing and tearing, then trundle brake sheet fatigue strength detects and does not pass through.
