When the valve is installed, the flanges at the two ends of the valve are required to be aligned with the flanges of the pipelines at the two sides so as to ensure the installation quality. When the large valve is installed, the valve is lifted by lifting equipment, and then alignment operation is carried out. Because the valve is easy to shake after being lifted, the valve is not easy to control, and the valve is heavy, the lifting installation mode has certain danger. For this purpose, there are also techniques in which a large valve is supported by a support frame and then is docked with the pipes on both sides. Because the accuracy required when the valve is docked with the pipe is high, fine adjustment of the position of the supported valve is required during installation. However, the conventional support frame has a lifting function, but does not have a function of fine-tuning the position of the valve supported, as shown in the patent technology of CN 201921335458.7.

Specifically, the lifting platform comprises a bottom plate 1, and a supporting plate 4 arranged on the bottom plate 1 through a lifting device 2; two support means are mounted on the support plate 4.

The lifting device 2 can drive the supporting plate 4 to lift so as to match the installation height of the valve. The lifting device 2 in this embodiment may be implemented by a jack.

In order to make the support plate 4 more stable when lifting, a plurality of telescopic rods 3 are further arranged between the bottom plate 1 and the support plate 4, and the telescopic rods 3 can be positioned at four corners of the bottom plate 1. The telescopic rod 3 consists of an outer cylinder and an inner cylinder sleeved in the outer cylinder, and when the supporting plate 4 is lifted, the telescopic rod 3 can stretch and retract.

When the device is specifically arranged, the surface of the supporting plate 4 is provided with a sliding groove 8, two sliding blocks 11 capable of sliding along the sliding groove 8 are arranged in the sliding groove 8, and two supporting devices are respectively arranged on the two sliding blocks 11. Thus, the two support means can be moved closer to and further away from each other.

The arc-shaped supporting block 7 is provided with grooves 74 penetrating through the outer arc surface and the inner arc surface, and the grooves 4 are distributed along the circumference of the arc-shaped supporting block 7.

In addition, moving grooves 77 are provided on opposite side walls of the slot 74, and both ends of the fine adjustment mechanism are respectively engaged into the two moving grooves 77 and can move along the moving grooves 77. Correspondingly, two side plates of the U-shaped mounting block 6 are fixedly connected with two side walls of the arc-shaped supporting block 7 respectively, and a space is formed between the outer cambered surface of the arc-shaped supporting block 7 and the bottom of the U-shaped mounting block 6. Thus, the fine adjustment mechanism is not blocked by the U-shaped mounting block 6 when moving along the moving groove 77.

As shown in fig. 4, the fine adjustment mechanism includes a slide plate 75 having both ends respectively engaged into two moving grooves 77, a connection sleeve 76 provided on the slide plate 75, and a fine adjustment bolt 78 screwed with the connection sleeve 76.

The slide plate 75 is provided with a through hole communicated with the connecting sleeve 76, and when the fine adjustment bolt 78 is screwed, the fine adjustment bolt 78 can stretch back and forth, so that the length of the fine adjustment bolt extending out of the supporting surface of the arc-shaped supporting block 7 is adjusted.

In order to fix the position of the fine adjustment mechanism, a plurality of positioning holes 72 are formed in the outer surface of the arc-shaped supporting block 7, the positioning holes 72 are distributed on two sides of the slot 74, and after the position of the fine adjustment mechanism is adjusted, the fine adjustment mechanism can be locked by pushing the sliding plate 75 by the positioning bolts 73.

When the valve is installed, the valve is firstly hung on the supporting structure by using hanging equipment, so that two arc-shaped supporting blocks 7 respectively support the two ends of the valve. The valve is lifted to the connection position by the lifting device, then the fine adjustment mechanism is moved to the corresponding position according to the positions of the valve flange and the pipeline flange, and the fine adjustment bolt 78 is screwed to push the valve to conduct fine adjustment on the position of the valve until the valve flange is aligned with the pipeline flange. The trim bolt 78 may be a wing bolt or eye bolt that is easier to screw.
