Detailed Description

In the embodiment, as shown in fig. 1 to 3, the anti-falling mechanism of the aluminum alloy creeper comprises an unloading ejector rod 1, a reset spring 9, a swing block 3, a limiting shaft 4, a small tongue 11 and a six-tooth star wheel 5, wherein the unloading ejector rod 1, the reset spring 9, the swing block 3, the limiting shaft 4, the small tongue 11 and the six-tooth star wheel 5 are arranged on a wall-attached support 2 matched with the aluminum alloy creeper for use, one end of the reset spring 9 is connected with the wall-attached support 2, and the other end of the reset spring is connected with the swing block 3. The unloading ejector rod 1, the swing block 3 and the six-tooth star wheel 5 are rotatably connected with the wall-attached support 2, specifically, the screw lever 15 is connected with a cylinder, and the cylinder is connected with the wall-attached support 2 through a second pin shaft 7. And the six-tooth star wheel 5 is connected with the wall-attached support 2 through a third pin shaft 12. Unloading ejector pin 1, six tooth star gears 5 use with the cooperation of aluminum alloy climbing frame respectively, seted up recess 8 on the pendulum piece 3, little tongue 11 is embedded in recess 8 set up slottedly 16 on the side of little tongue 11, be equipped with torsional spring 17 in the groove 16, pass pendulum piece 3, torsional spring 17 and little tongue 11 in proper order through first round pin axle 10 and be connected with attaching wall support 2. The torsion spring 17 is used for resetting the small tongue 11 after compression. When six star gears 5 anticlockwise rotation, can drive through little tongue 11 and set 3 clockwise rotation, reset spring 9 is used for setting 3's the reposition of redundant personnel, and spacing axle 4 is used for setting 3 location that reset of piece, when six star gears 5 clockwise rotation, little tongue 11 makes compression → open reciprocating motion under the stirring of the 5 teeth of a cogwheel of six star gears.

The unloading ejector rod 1 comprises a screw rod 15, a screw rod cylinder 14 and a supporting head 13, one end of the screw rod cylinder 14 is connected with the supporting head 13, the other end of the screw rod cylinder 14 is sleeved on the screw rod 15, and the length of the unloading ejector rod 1 is adjusted by rotating the screw rod cylinder 14.

The threaded-spindle cylinder 14 is rotatably connected to the support head 13. The support head 13 can rotate along the lead screw cylinder 14360 degrees.

The aluminum alloy climbing frame structure comprises a guide rail 6, a continuous equidistant anti-falling square hole is formed in the guide rail 6, specifically, the six-tooth star wheel 5 is matched with the anti-falling square hole for use, and the climbing frame is lifted and descended under the traction of external force (such as common lifting equipment in the climbing frame). When the position of the climbing frame needs to be fixed, the supporting head 13 is adjusted to a proper height, the supporting head 13 is rotated to a proper direction and clamped in the anti-falling square hole, and the anti-falling function is achieved.

The working principle is as follows:

the static operation state of the climbing frame: as shown in fig. 4, after the climbing frame is lifted to the working position, all the unloading ejector rods 1 are involved in working, and the length and the direction are adjusted, so that the supporting heads 13 are clamped in the anti-falling square holes, all the loads of the climbing frame are borne, and the load pressure of the lifting device is reduced.

Climbing a frame to rise: as shown in fig. 5, the unloading ejector rod 1 is in an open state, the guide rail 6 rises along with the lifting device, the six-tooth star wheel 5 rotates clockwise along with the guide rail 6, the teeth of the six-tooth star wheel 5 make the small tongue 11 reciprocate between the opening → compression → opening state in the rotating process, and the swinging block 3 does not intervene in the work, so that the normal rising motion of the guide rail 6, namely the rising of the climbing frame, is realized.

The descending working state of the climbing frame: as shown in fig. 6, when the climbing frame descends, the guide rail 6 moves downwards to drive the six-tooth star wheel 5 to move anticlockwise, the teeth of the six-tooth star wheel 5 stir the small tongue 11, and then the small tongue 11 drives the swing block 3 to rotate clockwise. When the teeth of the six-tooth star wheel 5 are not in contact with the small tongue 11, the swinging block 3 rebounds to the original position under the action of the return spring 9, so that the normal descending work of the guide rail 6, namely the descending of the climbing frame, is realized.

The anti-falling principle of the climbing frame is as follows: as shown in fig. 7, when the climbing frame suddenly falls during ascending operation or when the climbing frame suddenly falls during normal descending operation, the guide rail 6 quickly moves downwards to drive the six-tooth star wheel 5 to perform anticlockwise movement, the teeth of the six-tooth star wheel 5 stir the small tongue 11, and then the small tongue 11 drives the swing block 3 to rotate clockwise to a position between two teeth of the six-tooth star wheel 5; because the fast and normal decline state of the falling speed of climbing frame has great speed difference for the slew velocity of six star gears 5 is greater than the speed that resets of

pendulum block

3, and 3 lower extremes of pendulum block can not be in time kick-back and reset and can be blocked by six star gears 5 teeth of a cogwheel, and 3 upper ends of pendulum block are blocked by spacing axle 4, and the rotation of six star gears 5 is stopped by pendulum block 3 promptly, thereby has realized climbing frame prevents weighing down.

It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
