[0002] A tower crane is a revolving crane with a boom mounted on the top of a tall tower. It has a large working range and is mainly used for vertical transportation of materials and component installation in multi-story and high-rise building construction. It consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes the tower, boom, base, attachment rod, etc.

[0003] When drilling holes in tower crane parts, it is not convenient to position and clamp them for drilling due to their special shapes.

[0040] The punching mechanism includes a punching device 81, a multi-stage hydraulic rod 82 and a lower pressure frame 83. A multi-stage hydraulic rod 82 is installed on both sides of the placement frame 3 by bolts. A large telescopic rod and a small telescopic rod are provided on the multi-stage hydraulic rod 82. A lower pressure frame 83 for pressing and fixing the part body 5 is installed between the large telescopic rods of the two multi-stage hydraulic rods 82. The lower pressure frame 83 is located directly above the placement frame 3, and a punching device 81 is installed between the small telescopic rods of the two multi-stage hydraulic rods 82.

[0041] When punching the part body 5, the operator first puts the part body 5 into the placement frame 3. Since the edges of the upper part of the placement frame 3 are chamfered, the part body 5 can be placed in the placement frame 3 more easily. The bottom of the part body 5 will contact the horizontal strip plate 63 and the two supporting plates 73. Initially, the two top springs 62 are in a compressed state. The operator controls the telescopic rods of the two driving hydraulic rods 65 to shorten. The telescopic rods of the two driving hydraulic rods 65 drive the driving frame 66 and the long roller 67 to move downward. The long roller 67 moves downward and gradually separates from the inclined surface above the top block 61 and contacts the vertical surface on the top block 61. At this time, the two driving hydraulic rods 65 The telescopic rod stops shortening, and under the action of the long roller 67, the horizontal strip 63 and the top ball 64 will move toward the direction close to the part body 5, and the two top springs 62 will be compressed again, and the horizontal strip 63 and the top ball 64 will push the part body 5 to move, and a number of top balls 64 will contact one side of the part body 5, and the other side of the part body 5 will contact a number of guide balls 4. The top balls 64 and the guide balls 4 are used to perform preliminary correction and positioning on both sides of the part body 5, so that the position of the part body 5 is more accurate, so as to improve the accuracy and quality of the punching of the part body 5; when the driving frame 66 moves downward, it drives the two inclined slots 77 to move downward, and the two sides of the part body 5 are moved downward. Under the action of the inclined slot 77, the two rollers 76 will move toward the direction close to the column gear 74, and the two rollers 76 will drive the two racks 75 to move toward the direction close to the column gear 74. The two racks 75 will drive the two column gears 74 to rotate 45 degrees. The two column gears 74 will drive the two vertical shafts 72 to rotate 45 degrees. The two vertical shafts 72 will drive the two supporting plates 73 to swing 45 degrees. At this time, the two supporting plates 73 are not separated from the part body 5. When the long roller 67 contacts the vertical surface on the top block 61, the two rollers 76 just move to the middle of the two inclined slots 77. Then the operator controls the two large telescopic rods on the two multi-stage hydraulic rods 82 to shorten. The large telescopic rods on the two multi-stage hydraulic rods 82 will drive the small telescopic rods of the two multi-stage hydraulic rods 82, the lower pressing frame 83 and the punching device 81 to move downward together. The lower pressing frame 83 moves downward and contacts the top of the part body 5. Since the two sides of the part body 5 are in contact with the top ball 64 and the guide ball 4 respectively, the lower pressing frame 83 will press the part body 5 downward. The top ball 64 and the guide ball 4 play a guiding role. The part body 5 is limited and fixed by the horizontal strip plate 63, the supporting plate 73 and the lower pressing frame 83, which can avoid displacement of the part body 5 that has been corrected and positioned during punching, thereby further improving the accuracy and quality of the punching of the part body 5.Then the large telescopic rods of the two multi-stage hydraulic rods 82 stop moving, and then the small telescopic rods of the two multi-stage hydraulic rods 82 move downward, and the small telescopic rods of the two multi-stage hydraulic rods 82 drive the punching device 81 to move downward, and then the operator starts the punching device 81, and the punching device 81 punches the part body 5 that is limited and fixed. After the punching of the part body 5 is completed, the operator controls the large telescopic rods and the small telescopic rods of the two multi-stage hydraulic rods 82 to move upward and reset, and the punching device 81 and the lower pressing frame 83 also move upward and reset accordingly, and then the operator controls the telescopic rods of the two driving hydraulic rods 65 to continue to shorten, and the two driving hydraulic rods 65 are further shortened. The telescopic rod of 5 drives the driving frame 66 and the long roller 67 to move downward, and the long roller 67 moves downward and gradually separates from the vertical surface on the top block 61 and the inclined surface below. At this time, the telescopic rods of the two driving hydraulic rods 65 stop shortening. Under the action of the two top springs 62, the cross bar 63 and the top ball 64 will move away from the part body 5, and the top block 61, the top ball 64 and the cross bar 63 will separate from the part body 5. At this time, the two rollers 76 just move to the inner upper part of the two inclined grooves 77. Under the action of the two inclined grooves 77, the two racks 75 continue to move in the direction close to the column gear 74, and the two racks 75 drive the two column gears 7 4 rotates 45 degrees again, the two column gears 74 drive the two vertical shafts 72 to rotate 45 degrees again, the two vertical shafts 72 drive the two supporting plates 73 to swing 45 degrees again, at this time the two supporting plates 73 rotate 90 degrees in total, the two supporting plates 73 are separated from the part body 5, under the action of the part body 5's own gravity, the part body 5 will fall from the placement frame 3, and then the operator controls the telescopic rods of the two driving hydraulic rods 65 to extend and reset, the telescopic rods of the two driving hydraulic rods 65 drive the driving frame 66 and the long roller 67 to move upward, the long roller 67 moves upward and sequentially passes over the inclined surface below the top block 61 and the vertical surface on the top block 61 After the surface contacts the inclined surface above the top block 61, the two top springs 62 are compressed, and the telescopic rods of the two driving hydraulic rods 65 stop shortening. Under the action of the long roller 67, the horizontal strip plate 63 and the top ball 64 will move toward the direction close to the part body 5 and reset. Under the action of the two inclined grooves 77, the two racks 75 move away from the column gear 74. The two racks 75 drive the two column gears 74 to rotate 90 degrees in the opposite direction. The two column gears 74 drive the two vertical shafts 72 to rotate 90 degrees in the opposite direction. The two vertical shafts 72 drive the two supporting plates 73 to swing 90 degrees and reset. At this time, the two rollers 76 are located in the inner lower part of the two inclined grooves 77. ;

[0043] The plurality of transverse rollers 93 on each correction plate 91 form a group.

[0044] When the two vertical shafts 72 rotate, they drive the two toggle blocks 95 and the two return springs 96 to rotate. After the two toggle blocks 95 come into contact with the two contact blocks 94, the two toggle blocks 95 drive the two contact blocks 94 to move toward each other. The two contact blocks 94 drive the two correction plates 91 and the two sets of transverse rollers 93 to move toward each other. The transverse springs 92 are stretched accordingly. The two sets of transverse rollers 93 push the part body 5 to move toward the middle and correct it, so that the processing position of the part body 5 is directly below 81, which can further improve the accuracy and quality of the punching of the part body 5. As the two toggle blocks 95 rotate, the two toggle blocks 95 will separate from the two contact blocks 94.
