[0025] Embodiment:
[0026] Figure 1It is a schematic diagram of the usage state of a condenser tube sheet baffle coaxial tooling, including a platform 1, a front end plate 8, multiple baffle plates 10, and a rear end plate 9 that can be arranged on the platform 1. The platform 1 is also provided with a fixing clamp 2, and the fixing clamp 2 is provided with a fixing groove. The entrance of the fixing groove is in a flared form. The front end plate 8, multiple baffle plates 10, and the rear end plate 9 can be embedded in the fixing groove for quick positioning and then fixation.
[0027] It also includes several plug heads 5. A perforation 507 is opened at the center of the plug heads 5. The several plug heads 5 can be installed into the holes of the front end plate 8 or the multiple baffle plates 10 or the rear end plate 9 in multiple rows. It also includes multiple auxiliary brackets 3. Auxiliary wheels 4 are arranged on the auxiliary brackets 3. A steel wire rope 7 passes through the plug heads 5 in the same row. The steel wire rope 7 hangs down from the auxiliary wheels 4 and is tied with a heavy object 6.
[0028] After placing multiple plates of the present utility model, install the plug heads 5 in 3 rows or multiple rows of holes, then pass the steel wire rope 7 through the plug heads 5 in the same row. The steel wire rope 7 hangs down after passing through the auxiliary wheels and is tightened by the heavy object. At this time, the states of each plug head and the steel wire rope can be observed. If the steel wire rope shows a ∧ or ∨ at one of the plug heads, it means that the steel wire rope is not in a horizontal state, indicating that the hole at this position is higher or lower and not coaxial with other holes. Therefore, this position needs to be processed. The present utility model uses the steel wire rope to judge whether the holes of the plates are coaxial, which is intuitive and convenient.
[0029] Figure 2 It is a schematic diagram of the plug head. The plug head 5 includes a penetrating rod 501 and a limiting plate 502. The penetrating rod 501 can extend into the holes of the front end plate 8 or the multiple baffle plates 10 or the rear end plate 9. The limiting plate 502 is fixedly connected to the penetrating rod 501, and the penetrating rod 501 and the limiting plate 502 are provided with the perforation 507 for passing the steel wire rope 7.
[0030] A first flared edge 505 is arranged at the outer end of the penetrating rod 501. A first flared opening 506 is inside the first flared edge 505. The first flared opening 506 serves as the entrance and exit of the perforation 507.
[0031] A second flared edge 503 is arranged at the outer end of the limiting plate 502. A second flared opening 504 is inside the second flared edge 503. The second flared opening 504 serves as the entrance and exit of the perforation 507.
[0032] The first flared opening 506 and the second flared opening 504 are used for quickly passing the steel wire rope.
[0033] Figure 3 is Figure 1Partial enlarged schematic diagram in the middle. A fixing piece 301 is provided at the end of the auxiliary bracket 3. The fixing piece 301 can be attached to the rear end plate 9 and fixed by bolts (not shown). A positioning plate 302 is provided at the upper end of the fixing piece 301. The positioning plate 302 can be attached to the edge of the corresponding row of plugs 5, so that the upper surface of the auxiliary wheel 4 is flush with the perforation 507. The positioning plate can be positioned at the lower edge of the plug, that is, the lower edge of the limiting plate 502. The upper surface of the auxiliary wheel is set such that when the positioning plate just fits the lower edge of the limiting plate 502, the steel wire rope is exactly in a horizontal state. This can quickly install the auxiliary bracket and prevent wasting time by searching for the appropriate position multiple times.
[0034] Working principle:
[0035] ① Arrange the tube sheet and baffle plates on the working platform in sequence according to the construction drawing.
[0036] ② Evenly arrange several plugs on the holes of the tube sheet and baffle plates.
[0037] ③ Hang a heavy object on the steel wire rope at the end of the module.
[0038] ④ Pass a wire with a diameter of φ0.4 through each plug in sequence. After the steel wire rope passes through the roller bracket, the heavy object
[0039] shows a natural falling state.
[0040] ⑤ Check whether the steel wire rope in the middle of each baffle plate is straightened.
[0041] The front end plate 8, multiple baffle plates 10, and rear end plate 9 can be arranged in the fixed clamp. Select 3 rows or other numbers of rows, install the plugs one by one, and thread the steel wire rope. According to various situations such as the horizontal state of the steel wire rope, whether ∧ or ∨ appears, whether it fits the edge of the perforation 507, and whether the distance from the edge of the perforation 507 is not much different, etc., to judge whether the plates are coaxial. If they are not coaxial, then deal with it. When the worker discriminates, carefully observe the state of the steel wire rope. Similarly, it can be seen whether there is a small deviation in the steel wire rope, which can also judge whether the holes are extremely coaxial.
[0042] Embodiment 2:
[0043] On the basis of Embodiment 1, install a simple level (not shown) beside each plug on the steel wire rope, which can observe whether the position is horizontal. Therefore, it can accurately judge whether the coaxiality of the holes is good.
[0044] The above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention all fall within the scope of the technical solution of the present invention.
