Description

Technical Field

[0001] This utility model relates to the technical field of long bolt installation in pumped storage power stations, specifically to a long bolt lifting and screwing installation device. Background Technology

[0002] Conventional pumped storage power station seat rings are all equipped with long bolts for tightening. Each bolt weighs up to 275KG and is 3500mm long. Both ends of the long bolts are provided with external threads. There are multiple deep holes on the top wall of the pumped storage power station seat ring, and a long bolt is installed in each deep hole. For long bolts, the current installation method involves installing a lifting mechanism on the bottom wall of the pumped storage power station's seat ring. This mechanism lifts the long bolt into a deep hole, and then a clamping assembly clamps the outer wall of the bolt and screws it in, connecting the long bolt to the internal thread at the inner end of the deep hole. This causes the outer thread at the bottom of the long bolt to protrude from the deep hole. However, this method has several drawbacks. First, the clamping assembly needs to hold the unthreaded portion of the long bolt's outer wall (clamping the threaded portion would damage the threads), inevitably resulting in the bottom of the long bolt protruding too far from the deep hole, leading to poor installation results. Second, since the long bolts are up to 3500mm long, the lifting height requirement for the lifting mechanism is high. Due to space constraints, this method is difficult to install within the limited space of the pumped storage power station's seat ring, and it is also difficult to reposition the bolt. In short, this method is not only inefficient but also costly. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a long bolt lifting and screwing installation device that improves installation effect, efficiency and cost.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A long bolt lifting and tightening installation device includes a lifting assembly, a tightening component, a clamping component, and two lifting mechanisms. The two lifting mechanisms are suspended on the top wall of the pumped storage power station's seat ring and arranged opposite each other on both sides of a deep hole in the top wall. The lifting assembly is provided with an internal threaded hole for threaded connection with the bottom end of the long bolt. The two lifting mechanisms are detachably connected to the lifting assembly and are used to lift the lifting assembly to lift the long bolt. The tightening component and the clamping component are used for threaded connection with the bottom end of the long bolt and drive the long bolt to rotate when they are mutually clamped.

[0006] As a further improvement to the above technical solution:

[0007] The lifting assembly includes a lifting rod and a lifting seat. The two ends of the lifting rod are detachably suspended on two lifting mechanisms, the lifting seat is located on the lifting rod, and the internal threaded hole is located on the lifting seat.

[0008] The lifting seat is provided with a through hole, the axis of which is perpendicular to the internal thread hole, and the lifting rod is movably inserted through the through hole.

[0009] The lifting seat includes a connecting cylinder and two connecting plates. One end of each connecting plate is fixed to one end of the connecting cylinder and they are arranged symmetrically with the center of the connecting cylinder as the center of symmetry. The internal threaded hole is located at the center of the connecting cylinder, and the through hole is located on the connecting plate.

[0010] The lifting seat is fitted with a movable sleeve that can rotate and move axially relative to the lifting seat. The lifting seat is provided with an anti-detachment part to prevent the movable sleeve from coming off the lifting seat. The screwing part is threadedly connected to the movable sleeve.

[0011] The movable sleeve has an inner convex ring at one end away from the screwing component, and the anti-disengagement part is an outer convex ring at the end of the lifting seat facing the screwing component. The inner convex ring is movably sleeved with the outer wall of the lifting seat, and the outer convex ring is movably sleeved with the inner wall of the movable sleeve.

[0012] The screwing component includes a threaded sleeve and a screwing rod disposed around the periphery of the threaded sleeve. One end of the threaded sleeve is coaxially provided with a threaded cylinder, which is threadedly connected to the movable sleeve.

[0013] The clamping component is connected to the screwing component via an anti-detachment rope.

[0014] The clamping element includes a clamping sleeve and a screwing part located on the periphery of the clamping sleeve. The screwing part is connected to the screwing element via an anti-loosening rope. The center of the clamping sleeve is provided with a clamping thread for threaded connection with the bottom thread of a long bolt.

[0015] The lifting mechanism includes a lifting device and a hook mounted on the lifting device. A lifting seat is provided on the top wall of the pumped storage power station seat ring. The lifting device is suspended on the lifting seat, and the hook is hooked onto the lifting assembly. The lifting device is a hand-operated hoist, an electric hoist, or a winch.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] This utility model discloses a long bolt lifting and tightening installation device. The process is as follows: First, the tightening component and the clamping component are sequentially fitted onto the bottom thread of the long bolt and threadedly connected to it. Next, the internal threaded hole of the lifting assembly is threadedly connected to the bottom thread. Then, the top of the long bolt is aligned with the deep hole above, and the lifting assembly is lifted using a lifting mechanism to lift the long bolt to the threaded position within the deep hole. Next, the clamping component is rotated to make the tightening component and the clamping component clamp together, and the connection between the lifting mechanism and the lifting assembly is removed. Finally, the long bolt is rotated by rotating the tightening component, causing the top of the long bolt to engage with the thread within the deep hole until the bottom thread of the long bolt extends out of the designated position within the deep hole. For disassembly, the lifting assembly, clamping component, and tightening component are unscrewed sequentially from the bottom thread. This long bolt lifting and tightening installation device has two main advantages. First, by rotating the long bolt through the cooperation of the tightening and clamping parts with the bottom thread, the length of the bottom thread extending out of the deep hole can be adjusted by adjusting the position of the tightening and clamping parts on the bottom thread, thus improving the installation effect. Second, by lifting the long bolt through the lifting mechanism suspended on the top wall of the pumped storage power station seat ring, the device reduces the impact of limited working space and facilitates the relocation and adjustment of the construction position. It is not only highly efficient but also low in cost. Attached Figure Description

[0027] Example 1:

[0028] Figure 1 and Figure 2 This invention illustrates an embodiment of the long bolt lifting and tightening installation device. The long bolt lifting and tightening installation device of this embodiment includes a lifting assembly 1, a tightening component 2, a clamping component 3, and two lifting mechanisms 4. The two lifting mechanisms 4 are both suspended on the top wall 5 of the pumped storage power station seat ring and are arranged opposite each other on both sides of the deep hole 51 on the top wall 5. The lifting assembly 1 is provided with an internal threaded hole 7 for connecting with the bottom thread 61 of the long bolt 6. The two lifting mechanisms 4 are detachably connected to the lifting assembly 1 and are used to lift the lifting assembly 1 to lift the long bolt 6. The tightening component 2 and the clamping component 3 are used to thread-connect with the bottom thread 61 of the long bolt 6 and drive the long bolt 6 to rotate when they are mutually clamped.

[0029] Usage procedure: First, sequentially mount the screwing component 2 and the clamping component 3 onto the bottom thread 61 of the long bolt 6 and thread them together. Then, thread the internal threaded hole 7 of the lifting assembly 1 onto the bottom thread 61. Next, align the top of the long bolt 6 with the deep hole 51 above, and then use the lifting mechanism 4 to lift the lifting assembly 1 to lift the long bolt 6 to the threaded position inside the deep hole 51. Then, rotate the clamping component 3 to make the screwing component 2 and the clamping component 3 clamp together, and disconnect the lifting mechanism 4 from the lifting assembly 1. Finally, rotate the screwing component 2 to rotate the long bolt 6, so that the top of the long bolt 6 engages with the thread inside the deep hole 51, until the bottom thread 61 of the long bolt 6 extends out of the designated position in the deep hole 51. For disassembly, simply unscrew the lifting assembly 1, the clamping component 3, and the screwing component 2 from the bottom thread 61 in sequence. This long bolt lifting and tightening installation device has two advantages. First, by rotating the long bolt 6 through the cooperation of the tightening part 2 and the clamping part 3 with the bottom thread 61, the length of the bottom thread 61 extending out of the deep hole 51 can be adjusted by adjusting the position of the tightening part 2 and the clamping part 3 on the bottom thread 61, thereby improving the installation effect. Second, by lifting the long bolt 6 through the lifting mechanism 4 suspended on the top wall 5 of the pumped storage power station seat ring, the device reduces the influence of limited working space and facilitates the relocation and adjustment of the construction position. It is not only highly efficient but also low in cost.

The structure is simple and easy to manufacture.

[0031] Furthermore, in this embodiment, the lifting seat 12 is provided with a through hole 8, the axis of which is perpendicular to the internal threaded hole 7, and the lifting rod 11 is movably inserted into the through hole 8. This facilitates the disassembly and assembly of the lifting assembly 1. In addition, the lifting rod 11 can also assist in rotating the long bolt 6.

[0032] Furthermore, in this embodiment, the lifting seat 12 includes a connecting cylinder 121 and two connecting plates 122. One end of each of the two connecting plates 122 is fixed to one end of the connecting cylinder 121 and they are symmetrically arranged with the center of the connecting cylinder 121 as the center of symmetry. An internal threaded hole 7 is provided at the center of the connecting cylinder 121, and a through hole 8 is provided on the connecting plate 122. Each connecting plate 122 is provided with a through hole 8, and the lifting rod 11 passes through the through holes 8 of the two connecting plates 122.

[0033] Furthermore, in this embodiment, the screwing component 2 includes a threaded sleeve 21 and a screwing rod 22 disposed around the threaded sleeve 21. In use, the threaded sleeve 21 is fitted onto the bottom thread 61 and threadedly connected to the bottom thread 61, and the threaded sleeve 21 is rotated by the screwing rod 22.

[0034] Furthermore, in this embodiment, the clamping member 3 includes a clamping sleeve 31 and a screwing part 32 disposed around the clamping sleeve 31. The clamping sleeve 31 has a clamping thread at its center for threaded connection with the bottom thread 61 of the long bolt 6.

[0035] Furthermore, in this embodiment, the lifting mechanism 4 includes a lifting device 41 and a hook 42 disposed on the lifting device 41. A lifting seat 52 is provided on the top wall 5 of the pumped storage power station seat ring. The lifting device 41 is suspended on the lifting seat 52, and the hook 42 is hooked onto the lifting assembly 1. The lifting device 41 can be a hand-operated hoist, an electric hoist, or a winch. In actual use, the hooks 42 of the two lifting mechanisms 4 are respectively hooked onto both ends of the lifting rod 11.

In this way, the movable sleeve 123 and the lifting seat 12 are prevented from detaching under the limiting action of the inner convex ring 125 and the outer convex ring. Specifically, the anti-detachment part 124 is provided at the end of the connecting cylinder 121 facing the screwing member 2 (the end opposite to the connecting plate 122), and the inner convex ring 125 is movably sleeved with the outer wall of the connecting cylinder 121.
