[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] like Figure 1-4 As shown, a civil engineering hoist comprises a support column 1 and a swing arm 7. A cylinder 4 is sleeved on the support column 1 near the swing arm 7. A ring 3 and a disk 2 are fixed on the cylinder 4 and the support column 1 respectively. An annular rack 12 is fixed on the inner wall of the ring 3. A gear 10 meshing with the annular rack 12 is rotatably connected to the disk 2. One end of the swing arm 7 is hinged to the outer arc surface of the ring 3, and a gear 10 is also rotatably connected to one side of the ring 3. There are two gears 10 on the ring 3, and the two gears 10 are meshed. One of the gears 10 on the ring 3 passes through the ring 3 and is fixedly connected to the hinged end of the swing arm 7. A motor 6 is fixedly installed on the top of the disk 2 and one side of the ring 3. The gear 10 meshing with the annular rack 12 and the other gear 10 installed on one side of the ring 3 are both driven by the motor 6.

[0024] By adopting this technical solution, a swing arm 7 is arranged to rotate on the support column 1, so that the device can increase the range of moving goods. Specifically, the main shaft of the motor 6 fixed on the disc 2 is fixed to the gear 10 arranged in the ring 3. Therefore, the gear 10 in the ring 3 can be rotated by the motor 6, thereby driving the annular rack 12 to rotate. The rotation of the circular rack 12 can drive the ring 3 to rotate. The rotation of the ring 3 drives the swing arm 7 to rotate. When the swing arm 7 rotates, the goods can be moved to different directions. In addition, when a person stands on the opposite side of the support column 1 of the crane, the goods can be delivered to the The position where the personnel are located, but the longer swing arm 7 will occupy a certain amount of space. Therefore, by setting the swing arm 7 to be hinged on the ring 3, it is possible to reduce the space occupied by the swing arm 7 without reducing the use function of the swing arm 7. The specific implementation method is that the main shaft of the motor 6 installed on one side of the ring 3 is fixed to another gear 10 on the side of the ring 3. Therefore, the other gear 10 on the side of the ring 3 can be rotated by the motor 6, and one of the gears 10 on one side of the ring 3 is driven by the other gear 10 to rotate, and one of the gears 10 on one side of the ring 3 rotates to drive the swing arm 7 to swing, and the swing of the swing arm 7 can achieve the above-mentioned effect.

[0025] like Figure 2 and Figure 4 As shown, a rack groove 14 is provided in the swing arm 7, and a slider 11 is also slidably connected in the swing arm 7. A gear 10 is also rotatably installed on one side of the slider 11, and the gear 10 on the slider 11 is meshed with the tooth surface of the rack groove 14. A motor 6 is also slidably installed on one side of the swing arm 7, and the gear 10 installed on one side of the slider 11 is driven by the motor 6.

[0026] By adopting this technical solution, by arranging a motor 6 on one side of the swing arm 7, the slider 11 can automatically slide on the swing arm 7 without human push. The specific implementation method is that the main shaft of the motor 6 arranged on one side of the swing arm 7 is fixed to the gear 10 installed on one side of the slider 11. Therefore, the gear 10 installed on one side of the slider 11 can rotate. Because the gear 10 installed on one side of the slider 11 is engaged with the rack groove 14, the gear 10 installed on one side of the slider 11 can move on the rack groove 14, thereby driving the slider 11 to slide.

[0027] like Figure 1 and Figure 4As shown, a distribution plate 5 is fixedly installed on the end of another gear 10 on one side of the ring 3 and the side of the swing end of the swing arm 7, and a distribution plate 5 is also rotatably installed on the top edge of the outer wall of the cylinder 4. The distribution plate 5 on the gear 10 is wound with a rope 8, one end of the rope 8 passes through the distribution plate 5 on the cylinder 4 and extends to be fixed to the distribution plate 5 on the swing arm 7. It also includes a suspension arm 9 and a steel rope 15 fixedly installed on the top of the support column 1, and a through hole 13 for the steel rope 15 to pass through is opened on the slider 11.

[0028] By adopting this technical solution, by setting up a distribution plate 5 and a rope 8, the swing end of the swing arm 7 can be pulled and lifted, so that when the swing arm 7 swings, it can be swung more easily by pulling and lifting the rope 8, and under the pulling and lifting of the rope 8, the structure of the swing arm 7 is more stable. The specific working method is that when another gear 10 on one side of the ring 3 rotates driven by the motor 6, the swing arm 7 swings, and the distribution plate 5 on the side of the gear 10 also rotates, thereby causing the rope 8 wound on the distribution plate 5 on the side of the gear 10 to contract or stretch. Because the rope 8 has an oblique pulling force on the swing arm 7, and the distribution plate 5 at one end of the swing arm 7 is fixed, when the swing arm 7 swings, the distribution plate 5 on the cylinder 4 will rotate, so that the rope 8 is always in a taut state. Therefore, when the swing arm 7 swings, the rope 8 will always have an oblique pulling force on the swing arm 7 without affecting the swing of the swing arm 7.

[0029] Working principle: After the goods are lifted to a certain height, the ring 3 rotates, driving the swing arm 7 to rotate. When it rotates to the target position, the slider 11 slides, driving the goods to move to the position of the personnel. When the personnel is on the opposite side of the support column 1, the swing arm 7 swings so that its end reaches the position of the personnel. Then, the slider 11 drives the goods to move to the personnel.

[0030] The wiring diagram of the motor 6 in the present invention is common knowledge in the art, and its working principle is a known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the motor 6 are not explained in detail.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
