Description

Technical Field

[0001] The utility model relates to the technical field of large-diameter valve production, in particular to human-machine collaborative lifting equipment for assembling valve covers of large-diameter valves. Background Art

[0002] When producing large-diameter valves, the valve cover, valve body, valve seat and other structures are all produced independently. After production, the staff use a crane with tools such as hooks and ropes to assemble the valves. During the assembly process, the staff need to first install the valve plate and valve stem into the valve body, and then install the valve cover on the upper part of the valve body. Finally, the remaining components are installed in sequence.

[0003] Because before installing the valve cover, the staff needs to first select one end of the wire rope, and then fix hooks on both ends of the wire rope. After the hooks are fixed, the staff will hang the hooks on the valve cover, and then hang the wire rope through the hooks on the external crane. After hanging, the staff can start the crane and slowly lift the valve cover through the crane. This lifting method can easily cause the lifted valve cover to be tilted, resulting in the valve stem being unable to align with the hole on the upper part of the valve cover during later assembly, increasing the overall installation difficulty. At the same time, it will also increase the instability and safety risks during the lifting process. Utility Model Content

The tightening assembly 7 includes a tightening threaded rod 71, the bottom surface of the cross 3 is rotatably connected to the tightening threaded rod 71, the outer surface of the tightening threaded rod 71 is threadedly connected to the height disk 72, the top surface of the height disk 72 is rotatably connected to the connecting rod 73 through a lug and a pin shaft, and a total of 4 groups of connecting rods 73 are provided, and one end of the connecting rod 73 is rotatably connected to the hanging rod 5 through a lug and a pin shaft.

[0028] By tightening the rotation of the threaded rod 71, the height plate 72 will be driven to move downward, which can cause the four groups of connecting rods 73 to shrink inward, thereby driving the four groups of hanging rods 5 to move inward, so as to achieve the clamping and fixation of valve covers of different diameters.

[0029] In this embodiment, the clamping component 65 includes a fixed block 651, one side of the suspension rod 62 is fixedly connected to the fixed block 651, the internal thread of the fixed block 651 is connected to the downward pressing threaded rod 652, the bottom surface of the downward pressing threaded rod 652 is rotatably connected to the downward pressing block 653, and one side of the downward pressing block 653 is in contact with the surface of the suspension rod 62.

[0030] The threaded rod 652 is pressed down to drive the pressing block 653 to move downward. When the pressing block 653 moves downward, the periphery of the valve cover can be clamped and fixed under the action of the supporting rod 63, which will also facilitate the subsequent lifting.

[0031] Example 2

[0032] like Figures 1-6 As shown, based on the above embodiment, this embodiment further provides the following content:

[0033] Positioning component 64 includes a dovetail groove 641 provided at the lower portion of the other side of suspension rod 62.

[0036] like Figures 1-6 As shown, based on the above embodiment, this embodiment further provides the following content:

[0037] The locking component 66 includes a track 661, one side of the suspension rod 62 is fixedly connected to the track 661, the inner wall of the track 661 is fixedly connected to the forward damping rod 662, one end of the forward damping rod 662 is fixedly connected to a blocking block 663, the blocking block 663 is located in the track 661 and slides, and one side of the blocking block 663 is fixedly connected to a shift block 664.

[0039] The working principle and use process of this utility model:

[0040] In use:

[0041] When in use, first, the staff connects the device to the manipulator through the lifting ring 2 and chooses to use the clamping part 65 or the positioning part 64. When the positioning part 64 needs to be used, at this time, it is only necessary to rotate the lifting rod 62 so that the positioning part 64 faces the valve cover. At this time, the connection and tightening threaded rod 71 are rotated. As the tightening threaded rod 71 rotates, the height plate 72 is driven to move downward. As the height plate 72 moves downward, the four groups of connecting rods 73 are driven to retract inward, thereby driving the four groups of hanging rods 5 to slide in the T-slot 4. As the hanging rod 5 moves, the four groups of clamping assemblies 6 are brought close to each other. When one side of the lifting rod 62 contacts the edge that needs to be positioned, the rotation of the tightening threaded rod 71 is stopped. At this time, the staff pulls the dial block 664, and the dial block 664 will drive When the locking block 644 is in the state of being moved downwards, the locking block 644 is moved downwards, and the positioning post 643 is moved downwards, so that the positioning post 643 is inserted into the bolt hole on the valve cover. At this time, under the action of the supporting rod 63, the valve cover can be lifted to the ground, avoiding the tilting when lifting. When not in use, it is only necessary to pull the locking block 644 so that the locking block 644 drives the positioning post 643 to move upwards and separate from the valve cover, and at the same time, squeeze the reset damping rod 646, and finally pass over the blocking block 663 and be blocked by the blocking block 663.

[0042] When the positioning column 643 cannot be used later, at this time, the hanging rod 62 will be rotated so that the clamping part 65 is located on one side of the valve cover, and then, the threaded rod 71 will be rotated and tightened so that the four groups of hanging rods 62 are close to each other. At this time, one side of the hanging rod 62 will contact the surface of the valve cover, and the rotation of the tightening threaded rod 71 can be stopped. At this time, the downward pressing threaded rod 652 is rotated. As the downward pressing threaded rod 652 rotates, it will drive the downward movement of the pressing block 653, and the valve cover can be clamped under the action of the supporting rod 63, which facilitates the subsequent lifting.
