Technical Field
[0001] This utility model belongs to the technical field of steel structure hoisting equipment, specifically relating to a shackle structure that can be remotely controlled for release. Background Technology
[0002] Currently, ordinary shackles are used during steel structure hoisting. After the steel columns and beams are hoisted into place, workers need to climb to the top of the column or the lifting lug of the beam to release the shackles. However, this construction method has the following problems: 1. Workers climbing to the top of the column or the lifting lug of the beam are working at height, which carries the risk of falling from a height; 2. Before hoisting, ladders and fall arrestors need to be tied to the steel columns, which consumes a lot of time and manpower, and the ladders will affect the binding of steel bars and the pouring of concrete; 3. When the cross-section of the steel column is small, the steel column will sway, which is not conducive to climbing. Therefore, it is an urgent problem to solve to develop a shackle that can be remotely controlled to release the hook instead of workers climbing to the top of the column or the lifting lug of the beam.

[0014] Reference Figure 1 and Figure 2 As shown, the present invention provides a remotely controllable shackle structure, including a shackle body 1, a bracket 2, a screw 3, a transmission component 4, an electric motor 5, a signal receiving and control module 6, a battery component 7, and a remote controller 8. Support 2 consists of sleeve 21, sleeve 22, and L-shaped frame 23, as follows: Figure 4 and Figure 5 As shown. The inner diameter of sleeve 21 is smaller than that of sleeve 22; sleeve 21 and sleeve 22 are joined together and have a threaded hole A24 at the joint; one end of the L-shaped frame 23 is vertically fixed to sleeve 21, and the other end is horizontally positioned above sleeve 22; the signal receiving control module 6 and the battery assembly 7 are set on the horizontal end face of the L-shaped frame, and the signal receiving control module 6 is connected to the remote controller 8 and the electric motor 5 respectively, and is electrically connected to the battery assembly 7; a buzzer 10 is also provided on the L-shaped frame 23 of the bracket 2, the buzzer 10 is electrically connected to the battery assembly 7, and is connected to the remote controller 8; the remote controller 8 sends a signal command to the signal receiving control module 6, and the signal receiving control module 6 controls the electric motor 5 to rotate according to the received signal command, thereby realizing remote unhooking and avoiding the risk of personnel climbing to the top of the column or the steel beam lug for high-altitude work; The shackle body 1 has a threaded hole B11 at one end and a through hole 12 at the other end, and the end with the through hole 12 is rigidly connected to the first sleeve 21; one end of the screw 3 is threadedly connected to the threaded hole A24, and the other end passes through the through hole 12 and is threadedly connected to the threaded hole B11; the screw 3 is connected to the electric motor 5 installed in the bracket 2 through the transmission assembly 4.
[0015] As a further implementation of this utility model, the screw 3 is formed by two hexagonal bolts fixedly connected end to end. The end of the screw 3 is located on the side of the threaded hole A24 away from the shackle body 1, and the tail is threadedly connected to the threaded hole B11 of the shackle body 1.
[0016] As a further implementation of this utility model, such as Figure 1 and Figure 3 As shown, the transmission assembly 4 includes a bolt sleeve 41, a bearing 42, a large gear 43, and a small gear 44. Most of the bolt sleeve 41 is fixed in the second sleeve 22 by the bearing 42. One end of the bolt sleeve 41 is fitted with the end of the screw 3, and the other end is fixedly connected to the large gear 43. The small gear 44 meshes with the large gear 43 and is connected to the electric motor 5 through the gearbox 9. The cross-section of the opening inside the bolt sleeve 41 is a regular hexagon, which matches the end of the hexagonal bolt.
[0017] Further, see Figure 1 As shown, the transmission assembly 4 also includes a switch assembly, which consists of micro switch A45 and micro switch B46. Both micro switches are connected to the remote control signal. Micro switch A45 is mounted on the large gear 43 and located inside the bolt sleeve 41. When the end of the screw 3 moves to the right and contacts micro switch A45, the remote control 8 generates a vibration alert and sends a signal command to the signal receiving control module 6. After receiving the command, the signal receiving control module 6 controls the electric motor 5 to cut off its power. Micro switch B46 is located on the edge of the threaded hole A24 and close to one end of the transmission assembly 4. When the end of the screw 3 moves to the left and contacts micro switch B46, the remote control 8 generates a vibration alert and sends a signal command to the signal receiving control module 6. After receiving the command, the signal receiving control module 6 controls the electric motor 5 to cut off its power.
[0018] As a further embodiment of this utility model, a fall prevention device is also provided on the shackle body 1. This fall prevention device consists of a ring 13 rigidly connected to the shackle body 1 and a steel wire rope 14 connected to the ring 13. The other end of the steel wire rope 14 is connected to a hoisting steel wire rope. Figure 1 As shown, the anti-fall device avoids the risk of the shackle body falling off after the unhooking action is completed.
[0019] The remote unhooking method of this utility model is as follows: The remote controller 8 sends a signal command. After receiving the remote control signal, the signal receiving and control module 6 controls the electric motor 5 to rotate. The speed reduction gearbox 9 reduces the output speed of the electric motor 5 while amplifying the torque and transmitting it to the pinion 44. The pinion 44 drives the large gear 43 and the bolt sleeve 41 to rotate. After the bolt sleeve 41 rotates, it drives the screw 3 to rotate. As can be seen from the principle of screw drive, the screw 3 will move horizontally while rotating, that is, the screw will exit from the threaded hole B11 of the shackle body 1 and move towards the micro switch A45 to achieve remote unhooking.
[0020] In this utility model, the remote control has two operating modes: 1. Forward rotation of remote control (used when fastening hook): When the nut at the end of screw 3 touches the micro switch B46, the remote control 8 will vibrate to indicate that the screw 3 is tightened in place, and the buzzer 10 will emit a 3-second buzzing sound (indicating that screw 3 is tightened in place) and automatically cut off the power to the electric motor to prevent damage to the electric motor and to prevent components from falling off due to accidental remote control operation. 2. Reverse operation of remote control (used when unhooking): When the nut at the end of the screw 3 reaches the micro switch A45, the remote control 8 will vibrate to indicate that the screw has been removed and the buckle has been released. At the same time, the buzzer 10 will emit a 3-second buzzing sound (indicating that the screw has been removed and the buckle has been released) and automatically cut off the power to the electric motor to prevent damage to the electric motor. Before operating the motor again after each power outage, you need to press and hold the unlock button on the remote control for 3 seconds to power on the electric motor again.
[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
