Description

Fitting tooling for inner cylinder and outer cylinder of pressure vessel

technical field

The utility model relates to a pressure vessel installation device, in particular to a fitting tool for an inner cylinder and an outer cylinder of a pressure vessel.

Background technique

At present, in the pressure vessel industry, there are two ways to fit the inner cylinder and the outer cylinder of the pressure vessel. The first is to fix the outer cylinder first; then, weld the track of the trolley inside the outer cylinder; then, connect the inner cylinder and the sliding trolley connected; after that, push the sliding trolley to drive the inner cylinder into the outer cylinder for fitting. In this fitting method, the track on the inner cylinder for the sliding trolley cannot be taken out after fitting, resulting in high cost of raw materials. Moreover, the rail cannot be taken out, and the weight of the entire pressure vessel is increased. The second type fixes the outer cylinder first, and then uses the hydraulic telescopic arm to send the inner cylinder into the outer cylinder for fitting. The hydraulic telescopic boom is needed in this fitting method, and the price of the hydraulic telescopic boom is high, and the maintenance cost of the hydraulic telescopic boom is relatively high. Therefore, the use cost of this fitting method is relatively high.

Utility model content

The technical problem to be solved by the utility model is to provide a fitting tool for the inner cylinder and the outer cylinder of the pressure vessel. The raw material cost of the fitting tool is lower, the pressure vessel is light in weight, and the use cost is lower.

In order to solve the above problems, the following technical solutions are provided:

The utility model is characterized in that the fitting tooling for the inner cylinder and the outer cylinder of the pressure vessel comprises a bottom plate, on which there is a horizontally arranged track, and the track is provided with a support for placing the outer cylinder. There is a first column on the bottom plate corresponding to one end of the track, and a second column on the bottom corresponding to the other end. The upper end of the first column is fixed with a horizontally arranged cantilever rod, and the cantilever rod is arranged toward the second column, away from the side of the first column Both one end of the cantilever rod and the second column have connecting rods for connecting with the inner cylinder.

There are two tracks, which are arranged parallel and side by side on the bottom plate, and the first column and the second column are both located on the bottom plate between the two tracks. There are two supports, both of which are located between the two tracks, and there are rollers at the bottom of the supports corresponding to the tracks, and the supports are connected to the tracks through the rollers.

Adopting the above scheme has the following advantages:

Because the fitting tooling for the inner cylinder and the outer cylinder of the pressure vessel of the present invention includes a bottom plate, there is a track on the bottom plate, a support on the track, a first column on the bottom plate corresponding to one end of the track, and a second column on the bottom corresponding to the other end. The upright column, the upper end of the first upright column is fixed with a cantilever rod, and the end of the cantilever rod far away from the first upright column and the second upright column are provided with connecting rods for connecting with the inner tube. When in use, first hoist the outer cylinder of the pressure vessel from the two connecting rods to the support; then, manually push the support to drive the outer cylinder to move to the side close to the first column, so that the outer cylinder is sleeved on the cantilever rod; Then, hoist the inner cylinder between the two connecting rods; after that, weld and fix the two ends of the inner cylinder with the two connecting rods, so that the inner cylinder is fixed on the two connecting rods; after that, manually push the support The seat moves to the side close to the second column, so that the outer cylinder and the inner cylinder fit together; finally, after the outer cylinder and the inner cylinder are fitted together, cut off the welding part of the connecting rod and the inner cylinder, and remove the fit The outer cylinder and inner cylinder can be used. The use of the fitting tool does not require welding rails in the inner cylinder, which reduces the cost of raw materials and reduces the weight of the entire pressure vessel. Moreover, the use of the combined tool does not require expensive hydraulic telescopic arms, and the use cost is low.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1, the feature of the fitting tooling for the inner cylinder and the outer cylinder of the pressure vessel of the present invention is that it includes a bottom plate 1 with a horizontally arranged track 7 on the bottom plate 1 and a support for placing the outer cylinder 9 on the track 7 4. There is a first column 2 on the bottom plate 1 corresponding to one end of the track 7, and a second column 6 is arranged on the bottom corresponding to the other end. The upper end of the first column 2 is fixed with a horizontally arranged cantilever rod 3, and the cantilever rod 3 faces the second column. 6, there are connecting rods 5 for connecting with the inner cylinder 10 on one end of the cantilever rod 3 away from the first column 2 and on the second column 6.

There are two rails 7 , which are arranged parallel and side by side on the bottom plate 1 , and the first column 2 and the second column 6 are both located on the bottom plate 1 between the two rails 7 . There are two supports 4, and they are all located between two tracks 7, and there are rollers 8 at the bottom of the supports 4 corresponding to the tracks 7, and the supports 4 are connected to the tracks 7 through the rollers 8.

During use, in order to save materials, the floor of the workshop can be used as the bottom plate 1 .

During work, the outer cylinder 9 of the pressure vessel is hoisted on the support 4 from the two connecting rods 5 . Then, manually push the support 4 to drive the outer cylinder 9 to move to the side close to the first column 2, so that the outer cylinder 9 is sleeved on the cantilever rod 3, as shown in FIG. 2 . Then, the inner cylinder 10 is hoisted between the two connecting rods 5 . Afterwards, the two ends of the inner cylinder 10 are welded and fixed together with the two connecting rods 5 , so that the inner cylinder 10 is fixed on the two connecting rods 5 . Afterwards, manually push the support 4 to move to the side close to the second column 6, so that the outer cylinder 9 and the inner cylinder 10 fit together, as shown in FIG. 3 . Finally, after the fitting of the outer cylinder 9 and the inner cylinder 10 is completed, the welding place between the connecting rod and the inner cylinder 10 is cut off, and the fitted outer cylinder 9 and inner cylinder 10 are removed.
