The rear arm 5 cooperates with the counterweight block 31 to balance the weight of the front arm 6, so that its center of gravity is always on the main frame 2. The front arm 6 is convenient for supporting and fixing the lifting structure 7 and the detection and positioning structure 8. The lifting structure 7 is convenient for lifting or transferring the object to be lifted. The detection and positioning structure 8 is convenient for pre-positioning the target point after lifting the goods, and then moving the lifting structure 7 to the bottom of the detection and positioning structure 8 so that the receiving block 16 receives the information. At this time, the lifting structure 7 can achieve accurate positioning of the goods for lifting or transfer of the location, so there is no need to worry about foreign objects blocking the line of sight or deviations due to angles. The control room 9 It is convenient for the driver to enter and drive the tower crane structure 1 to operate. The sliding rack 10, the fixed slide 11, the two drive motors 12 and the sliding gear 13 cooperate with each other to realize the detection and positioning structure 8 sliding to the specified position on the forearm 6.

A sliding groove 22 is cut on the limiting wheel 20. The limiting wheel 20 is convenient for engaging with the first gear 21 and being embedded in the sliding rack 10. The sliding groove 22 facilitates the limiting fixed plate 18 to be embedded in the sliding gear 13.

[0030] Further, such as Figure 2 As shown, the drive motor 12 is fixedly mounted on the fixed slide 11 by bolts, which facilitates the disassembly, installation, repair and maintenance of the drive motor 12. The first gear 21 and the first tooth groove 19 are meshed with each other, and the slide groove 22 and the limiting fixed plate 18 are engaged with each other, so that the sliding gear 13 is engaged with the sliding rack 10.

[0031] Further, such as Figure 3 As shown, the lifting structure 7 includes a sliding base 23, a moving wheel 33 rotatably installed at the end corner of the sliding base 23, a structure to be towed 24 arranged on the upper surface of the sliding base 23, and a lifting hook 25 arranged on the lower surface of the sliding base 23. The sliding base 23 facilitates the horizontal sliding of the lifting structure 7 in the forearm 6, the moving wheel 33 facilitates reducing the friction force of the sliding base 23 sliding in the forearm 6, the structure to be towed 24 facilitates driving the lifting structure 7 to slide horizontally in the forearm 6, and the lifting hook 25 facilitates lifting the goods to be lifted or transferred to another location and performing lifting operations on the goods.

[0032] Further, such as Figure 1 、 Figure 4 、 Figure 5 as well as Figure 6 As shown, a first traction structure 26 is provided on the end of the forearm 6 away from the control room 9, and a second traction structure 27 is provided on the end of the rear arm 5 close to the control room 9. The main frame 2 is composed of several identical support frames 32 spliced ​​together by bolts. The first traction structure 26, the second traction structure 27 and the structure to be towed 24 cooperate with each other to facilitate the horizontal sliding of the lifting structure 7 in the forearm 6.

[0033] Further, such as Figure 1 、 Figure 4 、 Figure 5 as well as Figure 6As shown, the first traction structure 26 and the structure to be towed 24 are connected by a first steel cable 28, and the second traction structure 27 and the structure to be towed 24 are connected by a second steel cable 29.

[0034] Another step, such as Figure 1 、 Figure 4 、 Figure 5 as well as Figure 6 As shown, the front arm 6 is connected to the top of the tower cap 4 through the third steel cable 30 at the end close to the first traction structure 26, and the rear arm 5 is connected to the top of the tower cap 4 through the fourth steel cable 34 at the end away from the tower cap 4. The rear arm 5 is embedded with a counterweight 31 at the end away from the tower cap 4. The third steel cable 30 facilitates the re-reinforcement of the front arm 6, and the fourth steel cable 34 facilitates the re-reinforcement of the rear arm 5.

[0035] like Figures 1-6 As shown, the principle of the tower crane hook precise positioning device provided in this embodiment is as follows: when using the device, the tower cap 4 should be rotated to a certain angle to ensure that the forearm 6 is above the object to be hoisted. At this time, the two drive motors 12 start to operate, and then the first gear 21 starts to rotate, thereby driving the fixed slide 11 to slide on the sliding rack 10. At this time, the high-intensity laser spotlight 15 can be turned on to aim at the target cargo. At the same time, the operator sitting in the control room 9 can use the camera 14 to observe whether the laser beam is aimed at the target cargo and can make fine adjustments if it is not accurate.

[0036] Then, under the action of the first traction structure 26, the second traction structure 27 and the to-be-traction structure 24, the lifting structure 7 can be moved to the bottom of the detection and positioning structure 8. At this time, it is necessary to ensure that the receiving block 16 is below the camera 14 and the high-intensity laser spotlight 15. At this time, the lifting hook 25 can lift the cargo.

[0037] When the device is transferred to the designated location, the lifting structure 7 will be moved as close to the main frame 2 as possible under the action of the first traction structure 26, the second traction structure 27 and the to-be-towed structure 24. Then, the two drive motors 12 start to operate, and the first gear 21 starts to rotate, thereby driving the fixed slide 11 to slide on the sliding rack 10. At this time, the high-intensity laser spotlight 15 can be turned on again to aim at the target location. At the same time, the operator sitting in the control room 9 can use the camera 14 to observe whether the laser beam is aimed at the target location and make fine adjustments if it is not.

[0038] Then, under the action of the first traction structure 26, the second traction structure 27 and the structure to be towed 24, the lifting structure 7 can be moved to the bottom of the detection and positioning structure 8. At this time, it is necessary to ensure that the receiving block 16 is below the camera 14 and the high-intensity laser spotlight 15. At this time, the lifting hook 25 can directly and accurately place the lifted goods at the target location.
