Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage heater production, in particular to a bracket used for assembling high-voltage heaters. Background Art

[0002] The tube bundle inside the high-pressure heater is mainly composed of a header, a serpentine tube and a cladding. During the assembly process of the tube bundle, the header needs to be placed vertically on the tooling platform, the bottom cladding is installed first, and then the serpentine tubes are installed layer by layer. Due to the large number of claddings and serpentine tubes and their heavy weight, supports need to be installed under the bottom cladding. Existing tooling supports all use steel pipe supports. First, the height between the bottom cladding and the assembly platform is calculated, and then the steel pipes are cut. Then, one end of the steel pipe is welded to the channel steel to support the cladding, and then the other end is welded to the assembly platform. This type of support has limitations. Each time, a large number of support plates and vertical support steel pipes need to be cut according to the distance between the bottom cladding and the assembly platform. Finally, the steel pipes are manually welded on the assembly platform one by one. Due to the large number of steel pipes and channel steel support plates, a lot of manpower and time are wasted each time. The tooling cannot be reused after being dismantled, and it is inconvenient to move the tooling position, which wastes materials and increases costs. Utility Model Content

[0014] The specific implementation scheme of the utility model is described in detail below in conjunction with the accompanying drawings.

[0015] like Figure 1~Figure 2The bracket for assembling a high-pressure heater shown in the figure, a bracket for assembling a high-pressure heater, comprises two relatively vertical sleeves 2, the bottoms of the two sleeves 2 are respectively hinged on the base 1, the two sleeves 2 can swing left and right around the hinges at the bottom relative to the vertical plane where the two sleeves 2 are located, screws 8 are respectively inserted from top to bottom at the top openings of the two sleeves 2, the upper parts of the two screws 8 are respectively extended outside the corresponding sleeves 2, and nuts 5 are respectively threadedly connected on the outer circumferences of the two screws 8 at the tops of the sleeves 2. When the nuts 5 are rotated, the screws 8 can Lifting and lowering are performed on the sleeve 2, and support pads 6 are fixed on the tops of the two screw rods 8 respectively. The tops of the two support pads 6 are fixedly connected to the horizontal support plate 7. A hydraulic cylinder 10 is connected to one side of the two sleeves 2 that swing along the hinged bottom. One end of the cylinder body of the hydraulic cylinder 10 is hinged on the base 1, and the upper end telescopic rod of the hydraulic cylinder 10 is inclined toward one side of the sleeve 2. The upper end of the telescopic rod of the hydraulic cylinder 10 is hinged to the outer wall of the sleeve 2. When the hydraulic cylinder 10 is extended and retracted, it can drive the sleeve 2 to tilt, so that the support plate 7 connected to the top is tilted and displaced.

[0016] Specifically, in order to adjust the height of the support plate 7 and adapt to high-pressure heater tube bundles of different sizes, the bottom of the support plate 7 is connected with two separated screws 8, and nuts 5 are respectively threaded on the two screws 8. When the nuts 5 are rotated, the two nuts 5 move axially on the screws 8 respectively, and the lower ends of the two screws 8 are respectively inserted into the sleeves 2. Due to the action of gravity, the nuts 5 are always at the top of the sleeves 2, and the screws 8 rise and fall relative to the nuts 5 in the sleeves 2, so that the height of the support plate 7 is adjustable and the whole is easy to disassemble. One side of the two sleeves 2 is connected to the hydraulic cylinder 10, and the hydraulic cylinder 10, the base 1 and the lower part of the sleeve 2 form a triangle, so that the support plate 7 can be stably supported and can be tilted for easy disassembly and installation.

[0017] A spanner 4 is extended on the outer circumference of the nut 5. The spanner 4 is for facilitating the rotation of the nut 5 relative to the screw rod 8.

[0018] In addition, the lower parts of the two sleeves 2 are connected with a connecting rod 9, which can increase the overall strength. A guide tube 3 extends inward from the top opening of the two sleeves 2, and the guide tube 3 is sleeved outside the screw 8. The guide tube 3 allows the screw 8 to expand and contract along the axial direction of the sleeve 2. Washers 11 are respectively arranged on the top of the two sleeves 2, and the washers 11 are pressed on the bottom of the nut 5. The washers 11 serve as a weighing plate that is in close contact with the nut 5 when it rotates, and have the characteristics of wear resistance.

[0019] The working process of the utility model is as follows:

[0020] According to Figure 1-2, first assemble the base 1 and the sleeve 2, install the guide tube 3, the wrench 4, the nut 5, and the screw 8 in sequence, then weld the support pad 6 to the support plate 7, and then weld the connecting rod 9 between the two sleeves 3 to make the connection between the two firmly, and finally install the cylinder end and the telescopic rod end of the hydraulic cylinder 10; after assembly, evenly arrange the assembly bracket on the assembly platform, adjust the support height of the screw 8 by rotating the wrench 4 until the support plate 7 is in close contact with the bottom layer of the tube bundle, and then install the bottom layer; after the tube bundle is assembled, rotate the wrench 4 to lower the height of the screw 8, and then use the hydraulic cylinder 10 to tilt and lay the assembly bracket down, and then remove the assembly bracket piece by piece, and this use is completed.
