Description

Technical Field

[0001] The utility model relates to the technical field of semicircular coil installation, in particular to an auxiliary device for assembling semicircular coils on the outer wall of a cylinder. Background Art

[0002] Many chemical equipment are equipped with semi-circular coils on their outer walls. The semi-circular coils are spirally arranged around the outer wall of the cylinder. When installed, the semi-circular coils are installed section by section. Because the semi-circular coils are arc-shaped, there will inevitably be gaps when they are assembled with the cylinder. Therefore, when assembling, the semi-circular coils need to be knocked to make them fit with the outer wall of the cylinder before welding. However, when knocking, it is easy to be limited by the knocking experience of the operators. Not only is the assembly efficiency low, but the semi-circular coils will be deformed by knocking if you are not careful, thus affecting the overall quality of the equipment. Summary of the invention

[0003] In order to solve the problem that the semicircular coils are easily deformed by knocking when they are knocked and assembled, the utility model provides an auxiliary device for assembling the semicircular coils on the outer wall of a cylinder.

[0004] The utility model is realized by adopting the following technical solutions:

[0005] A semicircular coil assembly auxiliary device for the outer wall of a cylinder comprises a coil pressing block, the bottom surface of the coil pressing block is provided with a semicircular notch adapted to the outer wall of the semicircular coil, a cover plate is fixed to the top surface of the coil pressing block, a first handle is fixed to the top surface of the cover plate, front and rear end portions of the cover plate respectively extend outward from the two ends of the axial direction of the coil pressing block to form a front extending end portion and a rear extending end portion, the front extending end portion and the rear extending end portion are both provided with vertically arranged internal threaded holes, and the two internal threaded holes are both provided with top screws used for pressing the semicircular coil during assembly.

[0006] When in use, hold the first handle and press the device onto the semicircular coil, press hard so that the semicircular notch of the coil pressing block fits with the semicircular coil, screw the two top screws so that the two top and bottom press the semicircular coil, and then make the semicircular coil fit with the outer wall of the cylinder.

[0007] Furthermore, the device also includes a wedge block, and a pressing opening is arranged along the axial direction of the semicircular notch of the coil pressing block and is matched with the wedge block. When assembling, due to the processing tolerance of the semicircular coil, there may still be a small gap between the semicircular coil and the outer wall of the cylinder after the top screw is adjusted. At this time, the wedge block can be inserted into the pressing opening, and then the wedge block can be tapped with a small hammer to adjust the gap between the semicircular coil and the outer wall of the cylinder. Although a small hammer is used for tapping, the small hammer taps the wedge block, and the semicircular coil is indirectly stressed by tapping the wedge block. In addition, when the top screw has completed most of the adjustment, the tapping of the wedge block is also a light tap, which will not cause obvious deformation of the semicircular coil.

[0008] Furthermore, there are two clamping openings which are symmetrically distributed on both sides of the semicircular notch, so that the adjustment direction is more comprehensive.

[0009] Furthermore, the cover plate is fixedly connected to the top surface of the coil pressing block by bolts. Different semicircular coils have different specifications, so coil pressing blocks of different specifications need to be matched. At this time, only the coil pressing block needs to be replaced, and the bolt fixing facilitates disassembly and installation.

[0010] Furthermore, a second handle is fixed to the tail end of the wedge block, which is convenient for operators to take the wedge block. The first handle is a U-shaped handle, and the second handle is round steel, which has a simple and practical structure.

[0011] The beneficial effects of the utility model are as follows: when the assembly auxiliary device in the utility model is used to assemble the semi-circular coil tube on the outer wall of the cylinder, it is only necessary to screw the top screw to achieve the matching of the semi-circular coil tube and the outer wall of the cylinder, without knocking the semi-circular coil tube, thus avoiding deformation of the semi-circular coil tube and effectively improving its assembly efficiency and assembly quality.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] The specific embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 7 As shown, an auxiliary device for assembling semicircular coils on the outer wall of a cylinder comprises a coil pressing block 3, the bottom surface of the coil pressing block 3 is provided with a semicircular notch 4 which is adapted to the outer wall of the semicircular coil 2, a cover plate 5 is fixed to the top surface of the coil pressing block 3, a first handle 6 is fixed to the top surface of the cover plate 5, front and rear end portions of the cover plate 5 respectively extend outward from the two ends of the axial direction of the coil pressing block 3 to form a front extending end portion and a rear extending end portion, the front extending end portion and the rear extending end portion are both provided with vertically arranged internal threaded holes 7, and the two internal threaded holes 7 are both provided with top screws 8 for pressing the semicircular coil 2 during assembly.

[0027] When in use, hold the first handle 6 and press the device onto the semicircular coil 2, press it tightly so that the semicircular notch 4 of the coil pressing block 3 fits with the semicircular coil 2, screw the two top screws 8 so that the two top and bottom press the semicircular coil 2, and then make the semicircular coil 2 fit with the outer wall of the cylinder 1.

[0028] In specific implementation, the device further includes a wedge block 9, and a pressing opening 10 is provided on the arc wall of the semicircular notch 4 of the coil pressing block 3, which is arranged through the axial direction of the semicircular notch 4 and is adapted to the wedge block 9. When assembling, due to the processing tolerance of the semicircular coil 2, there may still be a small gap between the semicircular coil 2 and the outer wall of the cylinder 1 after the top screw 8 is adjusted. At this time, the wedge block 9 can be inserted into the pressing opening 10, and then the wedge block 9 is tapped with a small hammer to adjust the gap between the semicircular coil and the outer wall of the cylinder 1. Although a small hammer is used for tapping at this time, the small hammer taps the wedge block 9, and the semicircular coil 2 is indirectly stressed by tapping the wedge block 9. In addition, when the top screw 8 has completed most of the adjustment, the tapping of the wedge block 9 is also a tapping, which will not cause obvious deformation of the semicircular coil 2.

[0029] In specific implementation, there are two clamping openings 10 which are symmetrically distributed on both sides of the semicircular notch 4, so that the adjustment direction is more comprehensive.

[0030] During specific implementation, the cover plate 5 is fixedly connected to the top surface of the coil pressing block 3 by bolts. Different semicircular coils 2 have different specifications, so coil pressing blocks 3 of different specifications need to be matched. At this time, only the coil pressing block 3 needs to be replaced, and the bolt fixing facilitates disassembly and installation.

[0031] In this specific embodiment, a second handle 11 is fixed to the tail end of the wedge block 9, which is convenient for operators to take the wedge block 9. The first handle 6 is a U-shaped handle, and the second handle 11 is round steel, which has a simple and practical structure.

[0032] The above is only a specific implementation of the utility model, which enables those skilled in the art to understand or implement the utility model. Although detailed descriptions are given with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments, and they should all be covered by the protection scope of the claims.
