Description

Technical Field

[0001] The present invention relates to the technical field of hook pulley detection, in particular to a detection device for a crane hook pulley block. Background Art

[0002] Crane hook and pulley blocks are an essential component of cranes, primarily used to lift and move heavy objects. They consist of a hook, pulley, and wire rope. The pulley blocks change the direction and force of the wire rope to achieve the lifting and moving of heavy objects. To ensure the safety and efficiency of equipment during operation, a crane hook and pulley block inspection device is required.

[0003] When a crane is working, it usually uses the rising of the hook and movable pulley to lift heavy objects. After a long time, the hook and movable pulley will have the following problems: 1. The constant contact and friction between the pulley and the wire rope will easily cause defects such as wear and cracks on the outer surface of the pulley. Continuous use may cause the risk of the wire rope being out of the groove or breaking. During the inspection process, it is difficult to operate due to its special shape; 2. The hook is exposed to the external environment for a long time. Under the influence of the external environment, the metal on the hook surface will gradually corrode and lose, weakening its carrying capacity, accelerating the aging of the hook and shortening its service life. Corrosion makes the hook surface rough and increases the difficulty of operation. 3. When the hook is lifting heavy objects for a long time, the inner and outer arc surfaces of the hook will wear out. Wear will reduce the wall thickness of the hook, weaken its load-bearing capacity, and stress concentration will easily occur at the worn part, which may lead to the risk of breakage. For this reason, a detection device for a crane hook pulley block is proposed. Summary of the Invention

When it moves to the appropriate position, it stops. At this time, the end of the driving rope 32 is wound into the top of the rotating wheel 71 and then wound out from the bottom of the rotating wheel 71. The end screw of the driving rope 32 is then installed in the second collecting turntable 33. Then control the second cylinder to extend forward, the telescopic frame 82 will move forward, and stop after moving to the specified position. At this time, the front ends of the first probe 87 and the second probe 892 just contact the outer surface of the rotating wheel 71 and the wheel groove 72. If there is still a gap in the front sides of the first probe 87 and the second probe 892 at this time, the precision rings on both sides can be loosened and the precision bars can be adaptively adjusted until the ends of the first probe 87 and the second probe 892 contact the rotating wheel 71. At this time, the clamp and the pin 862 are removed. After losing the restriction, under the action of the spring, the first probe 87 and the second probe 892 continue to be against the rotating wheel 71. At this time, the indicator light 88 will show green, and then the drive motor 37 is controlled to rotate. Driven by the synchronous belt 36, the rollers 38 on both sides will rotate simultaneously. During the rotation, the bevel teeth 35 engage with each other, and at the same time, the first collecting turntable 31 and the second collecting turntable 33 will be driven to rotate in the same direction. The first collecting turntable 31 will unwind the drive rope 32, and the second collecting turntable 33 will unwind the drive rope 32. During the winding and releasing process of the drive rope 32, the rotating wheel 71 will be driven to rotate. During this rotation process, the rotating wheel 71 will continue to rotate without contact slippage. During the rotation of the rotating wheel 71, the first probe 87 and the second probe 892 will continue to detect. When the first probe 87 or the second probe 892 moves to an area with holes or depressions, the first probe 87 or the second probe 892 will move forward under the pressure of the spring. At this time, the metal sheet 863 will move forward and contact the front sensing sheet 864. At this time, the indicator light 88 will show red. When the first probe 87 or the second probe 892 moves to an area with deformation or impurities, the first probe 87 or the second probe 892 will move backward. At this time, the metal sheet 863 will contact the rear sensing sheet 864. At this time, the indicator light 88 will show yellow. Then the micro motor is controlled to rotate to adjust the angle of the second probe 892 to detect different positions of the wheel groove 72, and the displayed results are recorded in real time. After the detection is completed, the above operation can be reversed.

The grinding paper 53 is loosely installed on the lifting frame 57 and is tensioned by the clamping plate 54.

[0024] Working principle: When it is necessary to detect the corrosion on both sides of the hook body 73, control the steering motor 42 to rotate, rotate the detection mechanism 5 to the specified position, repeat the above operation to clamp the pulley hook 7 between the adjusting frames 2, and then control the first cylinder 13 to extend upward. When the rack 14 moves to the appropriate position, it stops, and the positioning snap rings 26 on both sides are pulled outward, and then the screw 16 is controlled to start rotating. At this time, the adjusting frame 2 will move forward, and the tooth piece 22 will engage with the rack 14. During the engagement process, the tooth piece 22 rotates, and the rotation drives the pulley hook 7 to rotate. When the hook body 73 rotates to the horizontal forward direction, the screw 16 stops rotating. At this time, the positioning snap ring 26 is inserted into the slot and positioned again. Then the first cylinder 13 is controlled to descend, and the screw 16 rotates again. The hook body 73 is rotated and moved horizontally to the specified position. At this time, the hook body 73 is located between the sanding papers 53. Then, the rotating pieces on both sides are rotated to adjust the pressing plate 54 to the middle. Under the pressure of the pressing plate 54, the sanding paper 53 will be in close contact with the outer surface of the hook body 73, and the sanding paper 53 is tensioned. At this time, the swing motor 51 is controlled to rotate and swing left and right. Under the connection of the connecting block 521, the lifting frame 57 will move up and down back and forth on the guide bar 58. During the movement, the sanding paper 53 will continuously rub the outer surface of the hook body 73. The debris generated during the friction will fall into the collecting plate 55. The debris can then be weighed to judge the degree of corrosion, and the corrosion can be intuitively judged by the degree of wear of the sanding paper 53.
