[0002] A ball valve is a valve in which the closing member (ball) is driven by a valve stem and rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids. Among them, the hard-sealed V-type ball valve has a strong shearing force between its V-type ball core and the metal valve seat with surfacing hard alloy, and is particularly suitable for media containing fibers, tiny solid particles, etc. A hoisting device refers to mechanical equipment used in operations such as lifting, hanging, handling, and loading and unloading, and is usually composed of basic tools and accessories such as cranes, hoists, electric hoists, manual hoists, and hooks;

[0003] On both sides of the existing hoisting device, hooks are symmetrically arranged. The structure of the ball valve is generally set as a symmetric structure, and the two ends of the ball valve can be directly connected to the two hooks. However, according to actual needs, the ball valve may not be a left-right symmetric structure in design. When directly connecting its two ends during hoisting, there will be a problem of uneven force, which easily causes the ball valve to slip from the hoisting device and increases the safety hazard. Therefore, the utility model proposes a ball valve hoisting device to solve the above problems. Summary of the Utility Model

Detailed implementation mode

[0017] To deepen the understanding of the present utility model, the following will further elaborate on the present utility model in combination with embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation to the protection scope of the present utility model.

[0018] According to Figure 1 、 2 As shown in FIGS. 3, a ball valve hoisting device is proposed in this embodiment, which includes a roller rack 1, a main frame rod 2, a top beam 3, a telescopic rod 4 and an assembly plate 5. The top of the roller rack 1 is fixedly connected with the main frame rod 2. The top end of the main frame rod 2 is hinged with the top beam 3. One end of the top beam 3 is provided with a telescopic rod 4. A lifting mechanism is arranged on the back side of the roller rack 1. One end of the telescopic rod 4 is connected with a lifting tool assembly through the lifting mechanism. A rotating mechanism is arranged outside the main frame rod 2. The hoisting device is moved to the vicinity of the ball valve through the roller rack 1. First, the top beam 3 is driven by the rotating mechanism to rotate to adjust the hoisting height of the ball valve. Then, both sides of the lifting tool assembly are fixed to both sides of the ball valve. Then, the ball valve is driven by the lifting mechanism to move upward to complete the hoisting work. Among them, the lifting tool assembly can adjust the position of its force application point, so that the ball valves with misaligned structures are evenly stressed.

[0019] The lifting tool assembly includes an assembly plate 5, a connecting seat 6, a hook 7, a threaded ring 8, a lead screw 9 and a sliding frame 10. Hooks 7 are symmetrically and fixedly connected to the bottom of both ends of the assembly plate 5 through the connecting seat 6. Threaded rings 8 are symmetrically and fixedly connected to the top of both ends of the assembly plate 5. A lead screw 9 is rotatably connected inside the threaded ring 8. A sliding frame 10 is slidably connected to the outside of the assembly plate 5. One end of the lead screw 9 penetrates through the top of the sliding frame 10 and is threadedly connected thereto. One end of the threaded ring 8 is fixedly connected with a handle 11. The lead screw 9 can be driven to rotate on the top of the assembly plate 5 through the handle 11. The top of the sliding frame 10 is in threaded cooperation with the lead screw 9. The assembly plate 5 restricts the movement track of the sliding frame 10. When the lead screw 9 rotates forward and backward on the top of the assembly plate 5, the sliding frame 10 can linearly reciprocate on the outside of the assembly plate 5. The top end of the sliding frame 10 is connected with a steel wire rope 13 to change the position of the force application point on the assembly plate 5, so that the ball valve is evenly stressed and prevented from suddenly slipping.

[0020] The hook 7 includes a hook body, a rotating ring and a torsion spring. The top of the hook body is hinged with the rotating ring. A torsion spring is arranged between the hinge of the rotating ring and the top of the hook body. The bottom of the rotating ring is in contact with the bottom of the hook body. After fixing chains on both sides of the ball valve, press the rotating ring to rotate towards the inside of the hook body, then put the chain into the inside of the hook body, and use the elastic force of the torsion spring to drive the rotating ring to reset to prevent the chain from slipping out of the hook body.

[0021] The lifting mechanism includes a rotating roller 12, a steel wire rope 13 and a motor 14. The rotating roller 12 is hinged to the back side of the roller frame 1. The steel wire rope 13 is wound around the outside of the rotating roller 12. The motor 14 is installed on the back side of the roller frame 1. The output end of the motor 14 is fixedly connected to one end of the rotating roller 12. A pulley 17 is fixedly connected to one end of the top beam 3 and the telescopic rod 4. The steel wire rope 13 is in fit connection with the outer wall of the pulley 17. One end of the steel wire rope 13 is fixedly connected to the top end of the sliding frame 10. The motor 14 can drive the rotating roller 12 to rotate on the back side of the roller frame 1. When the motor 14 drives the rotating roller 12 to rotate counterclockwise, the steel wire rope 13 can be wound up to drive the ball valve to move upward through the lifting tool mechanism. When the motor 14 drives the rotating roller 12 to rotate clockwise, the steel wire rope 13 can be lengthened, and the steel wire rope 13 drives the ball valve to move downward through the lifting tool mechanism.

[0022] The rotating mechanism includes a first hydraulic cylinder 15 and a hinge seat 16. The first hydraulic cylinder 15 is hinged to the bottom of the main frame rod 2. The output end of the first hydraulic cylinder 15 is fixedly connected to the hinge seat 16. The bottom of the top beam 3 is hinged to the hinge seat 16. Reinforcing rods 20 are symmetrically and fixedly connected to both sides of the main frame rod 2. The output end of the first hydraulic cylinder 15 is connected to the top beam 3, and the top beam 3 is hinged to the top end of the main frame rod 2. Therefore, the output end of the first hydraulic cylinder 15 can drive the top beam 3 to rotate up and down. The first hydraulic cylinder 15 is connected to the bottom end of the main frame rod 2. The first hydraulic cylinder 15 can rotate along with the top beam 3 to avoid interference of the first hydraulic cylinder 15 with the rotation of the top beam 3.

[0023] A second hydraulic cylinder 18 is fixedly connected to the top of the top beam 3. The output end of the second hydraulic cylinder 18 is fixedly connected to a fixed seat 19. One end of the telescopic rod 4 is fixedly connected to the inside of the fixed seat 19. The output end of the second hydraulic cylinder 18 is fixedly connected to one end of the telescopic rod 4. The telescopic rod 4 can move along with the output end of the second hydraulic cylinder 18 to change the length of one end of the telescopic rod 4, and the hoisting position can be adjusted according to the size of the ball valve.

[0024] For this ball valve hoisting device, the handle 11 can drive the lead screw 9 to rotate on the top of the assembly plate 5. The top of the sliding frame 10 is in threaded fit with the lead screw 9. The assembly plate 5 restricts the movement track of the sliding frame 10. When the lead screw 9 rotates forward and backward on the top of the assembly plate 5, the sliding frame 10 can linearly reciprocate outside the assembly plate 5. The top end of the sliding frame 10 is connected to the steel wire rope 13 to change the position of the force application point on the assembly plate 5, so that the ball valve is uniformly stressed and prevents it from suddenly slipping.
