Description

Technical Field

[0001] The present application relates to the technical field of chemical equipment construction, and in particular to a reactor head welding fixture. Background Art

[0002] When welding the reactor head, the two adjacent plates need to be precisely aligned. The usual method is to weld lugs on both sides of the weld, then put the fixture on the two lugs, and finally use the wedge to adjust the position of the two adjacent plates. However, this operation method is inconvenient to disassemble the wedge because the wedge is an interference fit clamp, which in turn makes it inconvenient to disassemble the entire fixture. For this reason, the inventor proposes a reactor head welding fixture. Utility Model Content

[0032] Example 1

[0033] See also Figure 1-Figure 3 This embodiment provides a reactor head welding fixture to solve the problem that when the existing fixture is used for assembly and welding of the reactor head, the fixture is inconvenient to disassemble and assemble due to the interference fit of the wedge block.

[0034] In this embodiment, the reactor head welding fixture includes a fixed seat 20 fixedly connected to the first end of the support beam 10, and a movable seat 30 slidably connected to the second end of the support beam 10. The fixed seat 20 and the movable seat 30 are both provided with a slot 21 for clamping the ear 51 on the plate 50. An adjusting rod 40 is screwed into the interior of the support beam 10, and a connecting sleeve 32 is fixedly connected to the movable seat 30 and is rotatably connected to the adjusting rod 40.

[0035] In this embodiment, by screwing the adjusting rod 40 toward the inside of the support beam 10, the connecting sleeve 32 can be used to drive the movable seat 30 to move toward the fixed seat 20, thereby driving the two adjacent plates 50 to align by pushing the lifting ear 51, making the disassembly and assembly of the entire fixture more convenient.

[0036] Specifically, the support beam 10 is constructed as a whole into a longitudinal square column shape, and a through hole with an internal thread is opened inside the support beam 10 along the longitudinal direction of the support beam 10. The through hole is arranged parallel to the support beam 10 as a whole, and an avoidance groove 11 is also opened on the front and rear side walls of the support beam 10. The overall extension direction of the avoidance groove 11 is parallel to the longitudinal direction of the support beam 10, and the avoidance groove 11 remains conductive with the aforementioned through hole.

[0037] In addition, the fixed seat 20 and the movable seat 30 are both constructed in a U shape as a whole, and the fixed seat 20 and the movable seat 30 are both arranged vertically with the support beam 10 as a whole. The two side plates of the fixed seat 20 and the movable seat 30 are arranged symmetrically on the front and rear sides of the support beam 10. The card slot 21 is opened on the bottom plate of the fixed seat 20 and the movable seat 30, and the card slot 21 is used for the ear 51 welded on the plate 50 to pass through.

[0038] In addition, connecting plates 31 are welded on the inner sides of the two side plates of the movable seat 30. The connecting plates 31 are arranged vertically with the side plates of the movable seat 30 as a whole. The connecting sleeves 32 are welded between the two opposite connecting plates 31, and the two connecting plates 31 are arranged symmetrically on both sides of the connecting sleeves 32. The connecting sleeves 32 are arranged inside the through hole of the support beam 10 as a whole, and the connecting plates 31 can be slidably clamped inside the avoidance groove 11.

[0039] It should be noted that the adjusting rod 40 is integrally screwed into the through hole of the support beam 10 and is arranged parallel to the support beam 10. A smooth section 41 for sleeve-mounting the connecting sleeve 32 is provided on the adjusting rod 40. The outer diameter of the smooth section 41 is smaller than the outer diameter of the adjusting rod 40. The outer diameter of the connecting sleeve 32 is smaller than the outer diameter of the adjusting rod 40. The smooth section 41 and the adjusting rod 40 are integrally formed. When the adjusting rod 40 is screwed in or out of the support beam 10, the smooth section 41 rotates inside the connecting sleeve 32. The bosses at both ends of the smooth section 41 form a blocking effect on the connecting sleeve 32, so that the connecting sleeve 32 can slide along the longitudinal direction of the support beam 10 following the rotation of the adjusting rod 40, thereby driving the movable seat 30 to approach or move away from the fixed seat 20.

[0040] It should be understood that in this embodiment, the movable seat is driven to approach the fixed seat by rotating the adjusting rod, so as to achieve the alignment of the two adjacent plates. After the welding of the reactor head is completed, the tensioning effect on the two lifting ears can be released by rotating the adjusting rod in the opposite direction, thereby facilitating the disassembly and assembly of the entire fixture.

[0041] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present application.
