Detailed Description
The present invention will be further described in the following to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the present invention easy to understand.
As shown in fig. 1 to 4, a single-point suspension feedback type braking device comprises a bottom plate 1, a side plate 2 fixed on the bottom plate 1, a driving motor 3 fixed on the bottom plate 1, a winding drum 4 connected with the driving motor 3 and a steel wire rope 5 wound on the winding drum 4, wherein a turntable 6 abutted against the steel wire rope 5 is arranged on the side plate 2, uniformly distributed swinging blocks 7 are hinged on the circumference of the turntable 6, one end of the turntable 6 is connected with the swinging blocks 7, the other end of the turntable 6 is connected with a positioning spring 16 of the turntable 6, and a steel wire rope speed reducing mechanism and a winding drum locking mechanism which are driven when the swinging blocks 7 do centrifugal motion are respectively arranged on the upper side and the lower side of the turntable 6.
The steel wire rope speed reducing mechanism comprises a sliding sleeve 8 fixed on the side plate 2, a push rod 9 matched with the sliding sleeve 8 for vertical movement, a trapezoid block 10 connected with the push rod 9 and propped against the sliding sleeve 8, wedge blocks 11 positioned on the left side and the right side of the trapezoid block 10 and slidably mounted on the side plate 2, and a slide rod assembly 12 mounted on the side plate 2 for vertical sliding and propped against the wedge blocks 11. The sliding rod assembly 12 comprises a guide sleeve 121 fixed on the side plate 2, a sliding rod 122 arranged on the guide sleeve 121, a limiting boss 123 fixed on the sliding rod 122, a spring 124 sleeved on the sliding rod 122, one end of the spring is connected with the guide sleeve 121, the other end of the spring is connected with the limiting boss 123, and a circular friction block 125 fixed at the bottom of the sliding rod 122. When the device is used, the swinging block 7 on the turntable 6 moves at an abnormal high speed to perform centrifugal movement to be unfolded, the push rod 9 is pushed to move upwards, the push rod 9 drives the trapezoid block 10 to be matched with the wedge block 11, the sliding rods 122 on the two sides move downwards, the circular friction blocks 125 contact the steel wire rope 5, the steel wire rope 5 is pressed down to form a wavy line shape, and the speed reduction effect on the steel wire rope 5 is greatly improved.
The circular friction block 125 has a groove 125a on the outer circumference of the bottom. In use, the grooves 125a increase the contact area with the wire rope 5, increasing friction.
The wedge block 11 is provided with an inclined surface 11a which is arranged obliquely upwards and matched with the slide bar 122 at one end far away from the trapezoid block 10.
The winding drum locking mechanism comprises a swing rod 13 hinged on the bottom plate 1, a friction belt 14 fixed on the circumferential surface of the winding drum 4, and a limit spring 15 with one end connected with the side plate 2 and the other end connected with the swing rod 13, wherein the right end of the swing rod 13 is positioned at the lower side of the winding drum 4. The swing rod 13 comprises a straight rod 131 and a circular arc-shaped plate 132 connected with the straight rod. When the device is used, the swinging block 7 which performs centrifugal motion pushes the swinging rod 13 to rotate anticlockwise, and the circular arc-shaped plate 132 is contacted with the friction belt 14 to reduce the speed of the winding drum 4, so that the effect of braking the driving motor 3 is achieved.
The method of use of the invention is further described below:
when the rotary table is in work, when the rotating speed of the driving motor 3 is too high, the steel wire rope 5 drives the rotary table 6 to rotate, the swinging block 7 is opened after being subjected to centrifugal force, the push rod 9 is pushed upwards to rise, and the swinging rod 13 is pushed to swing. The push rod 9 makes the slide bar 122 move downwards, finally, the round friction block 125 contacts the steel wire rope 5, the speed of the steel wire rope 5 is reduced, after the swing rod 13 swings, the circular arc-shaped plate 132 contacts the friction belt 14 on the winding drum 4 in the rotating process, the rotating speed of the winding drum 4 is reduced, when the rotating speed of the driving motor 3 is gradually recovered to be normal, the swing block 7 stops centrifugal swing, all braking and decelerating are stopped, and the driving motor 3 works normally.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
