[0021] The beneficial effects of the present invention are as follows:

[0022] 1. Through the setting of the protection mechanism of the present invention, when using the connection device, the camera takes pictures of the threads of the threaded column. When the remote control system analyzes that the thread deformation of the threaded column exceeds 10 degrees or the wear exceeds 10%, at this time, the electric telescopic rod is controlled to extend to clamp the threaded column. In addition, the remote control system can also control the operation of the biaxial motor to move the threaded column outward from the spiral frame until the fixing groove of the threaded column reaches the position where the clamping plate is located. At this time, the electric telescopic rod works again to make the clamping plate enter the fixing groove to fix the position of the threaded column, avoiding the threaded column from detaching from the spiral frame due to the wear of the threads of the threaded column, thereby further reducing the probability of danger, ensuring the stability of the work, and realizing the inspection operation of the threads when the connection device is working.

[0023] 2. Through the setting of the rotating cylinder of the present invention, since the rotating cylinder is sleeved on the outer surface of the threaded column, the rotating cylinder can prevent the water vapor in the environment from directly acting on the outer surface of the threaded column, reducing the probability of corrosion of the threads of the threaded column by the water vapor in the environment, realizing the protection of the threaded column, and extending the service life of the threaded column.

[0024] 3. Through the combined use of the first oil injection mechanism and the second oil injection mechanism of the present invention, both the first oil injection mechanism and the second oil injection mechanism inject lubricating oil onto the outer surface of the threaded column at regular intervals. The first oil injection mechanism injects lubricating oil onto the outer surface of the threaded column through the rotating cylinder, and the second oil injection mechanism injects lubricating oil onto the outer surface of the threaded column through the upper fixed nut. Both are at relatively high positions. Therefore, the injected lubricating oil will be evenly smeared in the spiral frame under the rotation of the threaded column, reducing the amount of air entering the threaded connection part between the spiral frame and the threads of the threaded column, and can lubricate the threads of the spiral frame and the threaded column, reducing the friction between the two, thereby reducing wear, and also reducing the probability of corrosion of the threads of the threaded column and the spiral frame by the water vapor in the environment, providing good protection for the threaded column and the spiral frame, and extending the service life of the threaded column and the spiral frame.

Detailed implementation manners

[0036] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0037] Example: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 ,Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown in Figure 7 , Figure 8 , Figure 9 and Figure 10 , a connecting device for a turnbuckle for port machinery includes a screw frame 1 and a fixing rod 2 fixedly connected inside the screw frame 1. A control board is installed on the fixing rod 2, and a signal transceiver device is integrated on the control board. The control board is controlled by a remote control system (the control board, the signal transceiver device and the remote control system are all prior arts, not shown in the figure and not described in detail). The connecting device further includes: a connecting mechanism 3 fixedly connected to the fixing rod 2. The connecting mechanism 3 includes a threaded column 303 threadedly connected to the screw frame 1. A fixing groove 306 is formed on the outer surface of the threaded column 303. The connecting mechanism 3 further includes a double-shaft motor 301 installed on the fixing rod 2. The double-shaft motor 301 is electrically connected to the control board and controlled by the control board. Output ends of the double-shaft motor 301 are fixedly connected with hexagonal prism shafts 302. One end of the threaded column 303 close to the double-shaft motor 301 is provided with a hexagonal prism groove. The inner surface of the hexagonal prism groove fits with the outer surface of the hexagonal prism shaft 302. The end of the threaded column 303 is fixedly connected with a connecting frame 304. A locking rod 305 is installed on the connecting frame 304. Outer surfaces of the two hexagonal prism shafts 302 are fixedly connected with rotating cylinders 307. The rotating cylinders 307 are sleeved on the outer surface of the threaded column 303, preventing moisture in the environment from directly acting on the outer surface of the threaded column 303, protecting the threaded column 303 and extending the service life of the threaded column 303. Fixing nuts 308 are fixedly connected to both ends of the screw frame 1. The fixing nuts 308 are threadedly connected to the threaded column 303.

[0038] During use, first install the threaded column 303 inside the screw frame 1. At this time, align the hexagonal prism groove of the threaded column 303 and insert it into the hexagonal prism shaft 302. Then, start the double-shaft motor 301 to drive the threaded column 303 to rotate through the hexagonal prism shaft 302 and the hexagonal prism groove, so that the threaded column 303 is installed inside the screw frame 1 until the connecting frame 304 contacts the fixing nut 308. Then, install the rigging in the connecting frame 304 through the locking rod 305. When it is necessary to adjust the turnbuckle to meet the tension requirements under different working conditions, start the double-shaft motor 301 at this time to make the hexagonal prism shaft 302 rotate, and then drive the threaded column 303 to rotate through the hexagonal prism groove, so that the threaded column 303 extends or retracts on the screw frame 1 to meet the tension requirements under different working conditions.

[0039] As Figure 5 , Figure 6 , Figure 7 , Figure 9 and Figure 10As shown in the figure, the connecting device further includes a through groove 4 opened at the end of the spiral frame 1. A protection mechanism 5 is installed in the through groove 4. The protection mechanism 5 includes an electric telescopic rod 501 fixedly connected in the through groove 4. The electric telescopic rod 501 is electrically connected to the control board and is controlled by the control board. The output end of the electric telescopic rod 501 is fixedly connected with a clamping plate 502. The clamping plate 502 is adapted to the fixing groove 306 and is connected to the threaded column 303 through a thread. The protection mechanism 5 further includes a through groove 503 opened in the spiral frame 1 and communicating with the inside of the through groove 4. The clamping plate 502 is slidably connected to the through groove 503. An inspection camera 8 fixedly connected in the through groove 4 has its shooting end facing the threaded column 303. The inspection camera 8 is electrically connected to the control board and is controlled by the control board.

[0040] After the threaded column 303 is installed in place in the spiral frame 1, the electric telescopic rod 501 is started at this time, so that the clamping plate 502 moves into the through groove 503 until the clamping plate 502 fits against the outer surface of the threaded column 303. In this way, the threaded column 303 can be stably installed in the spiral frame 1. When it is necessary to adjust the turnbuckle to meet the tension requirements under different working conditions, the biaxial motor 301 is started at this time to make the hexagonal prism shaft 302 rotate, and then the threaded column 303 is driven to rotate through the hexagonal prism groove, so that the threaded column 303 extends or retracts on the spiral frame 1 to meet the tension requirements under different working conditions. During this process, since the inspection camera 8 is in a state of facing the threaded column 303, the threaded column 303 can be photographed by the inspection camera 8. When the remote control system analyzes that the thread deformation of the threaded column 303 exceeds 10 degrees or the wear exceeds 10%, if the clamping plate 502 is facing the threaded section of the threaded column 303, the control board controls the electric telescopic rod 501 to extend again to clamp the threaded column 303, avoiding the instability of the connection with the spiral frame 1 due to the wear of the thread of the threaded column 303 and reducing the probability of danger; when it is analyzed that the thread deformation of the threaded column 303 exceeds 10 degrees or the wear exceeds 10%, if the clamping plate 502 is facing the fixing groove 306, the electric telescopic rod 501 works at this time, so that the clamping plate 502 enters the fixing groove 306 to fix the position of the threaded column 303, avoiding the threaded column 303 detaching from the spiral frame 1 due to the wear of the thread of the threaded column 303, thereby further reducing the probability of danger and ensuring the stability of the work.

[0041] Such as Figure 1 、 Figure 3 and Figure 9As shown in the figure, the connecting device further includes: a first oil injection mechanism 6 installed on the fixed rod 2 and internally communicating with the connecting mechanism 3. The first oil injection mechanism 6 includes a first oil storage tank 601 fixedly connected to the lower surface of the fixed rod 2. An oil filling hole is provided on the first oil storage tank 601, and a sealing plug is installed in the oil filling hole. A first pump body 603 is installed on the outer surface of the first oil storage tank 601. The first pump body 603 is electrically connected to the control board and is controlled by the control board. A first oil suction pipe 602 is fixedly communicated with the first oil storage tank 601. The first oil suction pipe 602 is fixedly communicated with the first pump body 603. The output end of the first pump body 603 is fixedly communicated with a first oil injection pipe 604. The oil injection end of the first oil injection pipe 604 is fixedly connected with a fixed ring 605. The fixed ring 605 is rotatably connected to the top of the lower rotating cylinder 307. An oil injection hole 606 is provided at the top of the lower rotating cylinder 307. The oil injection hole 606 is located within the fixed ring 605 and is internally communicated with the fixed ring 605.

[0042] During use, the first pump body 603 is periodically controlled by the control board to operate. When the first pump body 603 operates, the first pump body 603 will extract lubricating oil (or other protective reagents) in the first oil storage tank 601 through the first oil suction pipe 602, and inject the extracted lubricating oil into the fixed ring 605 through the first oil injection pipe 604. Then, it is injected into the lower rotating cylinder 307 through the oil injection hole 606, so that the lubricating oil is evenly smeared on the thread of the threaded column 303, realizing the lubrication of the threaded column 303. And the lubricating oil will be evenly smeared in the spiral frame 1 under the rotation of the threaded column 303, reducing the amount of air entering the threaded connection part between the spiral frame 1 and the thread of the threaded column 303, and being able to lubricate the threads of the spiral frame 1 and the threaded column 303, reducing the friction between the two, thereby reducing wear, and also reducing the probability of the moisture in the environment corroding the threads of the threaded column 303 and the spiral frame 1, providing good protection for the threaded column 303 and the spiral frame 1, and extending the service life of the threaded column 303 and the spiral frame 1.

[0043] Such as Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 9 and Figure 10As shown in the figure, the connecting device further includes a second oil injection mechanism 7 fixedly connected to the connecting mechanism 3 communicated with the fixed rod 2. The second oil injection mechanism 7 includes a second oil storage tank 701 fixedly connected to the upper surface of the fixed rod 2. An oil filling hole is provided on the second oil storage tank 701, and a sealing plug is installed in the oil filling hole. A second pump body 703 is installed on the top of the second oil storage tank 701. The second pump body 703 is electrically connected to the control board and is controlled by the control board. A second oil suction pipe 702 is fixedly communicated with the top of the second oil storage tank 701. The second oil suction pipe 702 is fixedly communicated with the second pump body 703. The output end of the second pump body 703 is fixedly communicated with a second oil injection pipe 704. An oil coating groove 705 is provided on the inner surface of the upper fixing nut 308. The oil coating groove 705 is internally communicated with the second oil injection pipe 704. The second oil injection pipe 704 is fixedly connected to the upper fixing nut 308.

[0044] During use, the second pump body 703 is periodically controlled by the control board to work, and the second pump body 703 works synchronously when the first pump body 603 works. When the second pump body 703 works, the second pump body 703 will extract lubricating oil (or other protective reagents) in the second oil storage tank 701 through the second oil suction pipe 702, and inject the extracted lubricating oil into the oil coating groove 705 through the second oil injection pipe 704, so that the lubricating oil is evenly smeared on the thread of the threaded column 303, realizing the lubrication of the threaded column 303. And the lubricating oil will be evenly smeared in the spiral frame 1 under the rotation of the threaded column 303, reducing the amount of air entering the threaded connection part between the spiral frame 1 and the threaded column 303, and being able to lubricate the threads of the spiral frame 1 and the threaded column 303, reducing the friction between the two, thereby reducing wear, and also reducing the probability of thread corrosion of the threaded column 303 and the spiral frame 1 by water vapor in the environment, providing good protection for the threaded column 303 and the spiral frame 1, and extending the service life of the threaded column 303 and the spiral frame 1.

[0045] The specific working principle of the present invention is as follows:

[0046] During use, first install the threaded column 303 in the spiral frame 1. At this time, align the hexagonal prism groove of the threaded column 303 and insert it into the hexagonal prism shaft 302. Then the double-shaft motor 301 can be started to drive the threaded column 303 to rotate through the hexagonal prism shaft 302 and the hexagonal prism groove, so that the threaded column 303 is installed in the spiral frame 1 until the connecting frame 304 contacts the fixing nut 308. Then install the rigging in the connecting frame 304 through the locking rod 305;

[0047] During the installation of the threaded post 303 in the screw bracket 1, since the inspection camera 8 is facing the threaded post 303 at this time, the inspection camera 8 is started to take a threaded picture of the threaded post 303. When the remote control system analyzes that the thread deformation of the threaded post 303 exceeds 10 degrees or the wear exceeds 10%, the biaxial motor 301 is controlled to work in reverse to screw out the threaded post 303 for repair and replacement;

[0048] After the threaded post 303 is installed in the screw bracket 1 in place, the electric telescopic rod 501 is started at this time, so that the clamping plate 502 moves into the through groove 503 until the clamping plate 502 reaches a position where it can fit the outer surface of the threaded post 303. In this way, the threaded post 303 can be stably installed in the screw bracket 1. When it is necessary to adjust the turnbuckle to meet the tension requirements under different working conditions, the biaxial motor 301 is started at this time to rotate the hexagonal shaft 302, and then the threaded post 303 is driven to rotate through the hexagonal groove, so that the threaded post 303 extends or retracts on the screw bracket 1 to meet the tension requirements under different working conditions. During this process, since the inspection camera 8 is facing the threaded post 303, the threaded picture of the threaded post 303 can be taken through the inspection camera 8. When the remote control system analyzes that the thread deformation of the threaded post 303 exceeds 10 degrees or the wear exceeds 10%, if the clamping plate 502 is facing the threaded section of the threaded post 303, the control board controls the electric telescopic rod 501 to extend again to clamp the threaded post 303, avoiding the unstable connection with the screw bracket 1 due to the wear of the thread of the threaded post 303 and reducing the probability of danger; when it is analyzed that the thread deformation of the threaded post 303 exceeds 10 degrees or the wear exceeds 10%, if the clamping plate 502 is facing the fixed groove 306, the electric telescopic rod 501 works to make the clamping plate 502 enter the fixed groove 306 to fix the position of the threaded post 303, avoiding the threaded post 303 disengaging from the screw bracket 1 due to the wear of the thread of the threaded post 303, thereby further reducing the probability of danger and ensuring the stability of the work;

[0049] And during the use process, the first pump body 603 is controlled by the control board at regular intervals. When the first pump body 603 works, the first pump body 603 will extract the lubricating oil (or other protective reagents) in the first oil storage tank 601 through the first oil suction pipe 602, and inject the extracted lubricating oil into the fixing ring 605 through the first oil injection pipe 604, and then inject it into the lower rotating cylinder 307 through the oil injection hole 606, injecting the lubricating oil from the upper direction of the lower threaded column 303 onto the threaded column 303. At the same time, when the first pump body 603 works, the second pump body 703 works synchronously. When the second pump body 703 works, the second pump body 703 will extract the lubricating oil (or other protective reagents) in the second oil storage tank 701 through the second oil suction pipe 702, and inject the extracted lubricating oil into the oil coating groove 705 through the second oil injection pipe 704, injecting the lubricating oil from the top of the spiral frame 1 into the spiral frame 1 and onto the threads of the threaded column 303, so that the lubricating oil is evenly smeared on the threads of the threaded column 303, realizing the lubrication of the threaded column 303. And the lubricating oil will be evenly smeared in the spiral frame 1 under the rotation of the threaded column 303, reducing the amount of air entering the threaded connection part between the spiral frame 1 and the threaded column 303, and being able to lubricate the threads of the spiral frame 1 and the threaded column 303, reducing the friction between the two, thus reducing the wear, and also reducing the probability of the moisture in the environment corroding the threads of the threaded column 303 and the spiral frame 1, providing good protection for the threaded column 303 and the spiral frame 1, and extending the service life of the threaded column 303 and the spiral frame 1.

[0050] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
