Technical Field

[0001] The utility model relates to the technical field of mechanical hoisting, in particular to a flange hoisting tool with an adjustable flange center of gravity. Background Art

[0002] Flange connection is easy to use and can withstand greater pressure. Flange connection is widely used in industrial pipelines. Most of the existing methods of lifting flanges are to hook a hook on a bolt hole of the flange, and then as the lifting rope is tightened, the hook tightly hooks the flange to complete the lifting.

[0003] However, there are some defects. Most flanges have uneven weight distribution. Lifting them directly with hooks will cause the flanges to tilt, which will cause inconvenience in the installation and use of the flanges and affect work efficiency. In order to deal with the above problems, improvements are made here, so a flange lifting tool with adjustable flange center of gravity is proposed. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A flange lifting tool with an adjustable flange center of gravity includes a flange body 1 and a lifting rod 2. The present invention also provides a lifting frame and a moving component. The above components are conventional components in the prior art and can be supported by the lifting frame and moved by the moving component. The specific structure and working principle will not be described in detail here. For details, please refer to the prior art disclosure.

[0022] A fixing frame 3 is installed on the lifting rod 2, two screw rods 4 are rotatably installed on the fixing frame 3, a driving gear 8 is rotatably installed on the fixing frame 3, the two screw rods 4 are connected to the driving gear 8 through a transmission mechanism, a power mechanism connected to the driving gear 8 is installed on the fixing frame 3, a movable plate 6 is threadedly installed on the two screw rods 4, a support frame 7 for lifting the flange body 1 is installed on the movable plate 6, a T-shaped through-rod 10 is slidably penetrated through the movable plate 6 through an elastic mechanism, and a limit block 11 cooperating with the flange body 1 is provided at the end of the T-shaped through-rod 10.

[0023] The transmission mechanism includes a transmission gear 9 installed on the end of the screw 4. The two transmission gears 9 are vertically meshed with the driving gear 8. As shown in the figure, the driving gear 8 and the transmission gear 9 are both bevel gears. Their vertical meshing realizes the power transmission of the drive motor 5, and can realize the synchronous rotation of the two screws 4 after the drive motor 5 is started. The direction of the thread on the screw 4 of this scheme is set according to the actual situation to ensure that the two movable plates 6 move closer or farther away synchronously.

[0024] The power mechanism includes a driving motor 5 mounted on the fixing frame 3 , the output shaft of the driving motor 5 rotates through the fixing frame 3 and is fixedly connected to the driving gear 8 . As shown in the figure, the driving motor 5 is located at the center of gravity of the fixing frame 3 .

[0025] The elastic mechanism includes a spring 12 sleeved on the outside of the T-shaped through rod 10, and the two ends of the spring 12 are elastically connected to the outer wall of the limit block 11 and the outer wall of the movable plate 6 respectively. The elastic potential energy provided by the spring 12 cooperates with the limit block 11 to be inserted into the opening of the flange body 1 to achieve the extrusion and push of the flange body 1, thereby ensuring the stability and balance of the flange body 1.

[0026] A limiting rod 13 is provided on the fixing frame 3 , and the limiting rod 13 is parallel to the screw rod 4 . The limiting rod 13 slides through the movable plate 6 , and the limiting rod 13 plays a limiting role to prevent the movable plate 6 from rotating together with the screw rod 4 .

[0027] The limiting block 11 is a trapezoidal column, and the outer wall of the limiting block 11 is polished. The polishing process ensures the smoothness of the outer wall, thereby preventing the limiting block 11 from causing damage to the inner wall of the opening on the flange body 1.

[0028] When the utility model is used, Figure 1As shown, the right half of the flange body 1 is heavier and the left half is lighter, so the center of gravity of the flange body 1 is on the right. During the lifting process with the help of components such as the support frame 7, the contact force between the right half thread and the support frame 7 is relatively large, which increases the force on the thread and accelerates the wear of the thread. At the same time, long-term use will cause damage to related components and shorten the service life of the equipment. Since the present solution is provided with a T-shaped through rod 10, a limit block 11 and a spring 12, with the help of the limit block 11 inserted into the opening on the flange body 1, and the restoring force provided by the spring 12 when compressed, the flange body 1 can be pushed to the middle and its center of gravity can be adjusted, thereby avoiding the occurrence of the above situation.

[0029] Specific:

[0030] In this solution, the driving motor 5 can directly drive the driving gear 8 to rotate, and the driving gear 8 can cooperate with the transmission gear 9 to drive the screw 4 to rotate. When the screw 4 rotates, the movable plate 6 can drive the support frame 7 to move, and the two groups of support frames 7 move close to each other. Figure 1 In the state shown, the flange body 1 can be hoisted.

[0031] In this solution, before the two support frames 7 approach to support and lift the flange body 1, the limit block 11 has already entered the opening on the flange body 1. As the drive motor 5 continues to rotate, the spring 12 will be in a compressed state, ensuring the force with which the limit block 11 is inserted into the opening on the flange body 1.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
