Description

Technical Field

[0001] The utility model belongs to the field of flame arresters, and in particular relates to a flame arrester which is convenient for hoisting. Background Art

[0002] Flame arresters are safety devices used to prevent the spread of flames of flammable gases or flammable liquid vapors. They are generally installed in pipelines that transport flammable gases or in pipelines connecting storage tanks to prevent the spread of flames. Flame arresters usually include a flame arrester housing, a flame arrester core and its housing, a pipe, a head, and fasteners. Since current flame arresters are generally welded or integrally cast, and have similar shapes, their specific shape and weight make it difficult to install them at high places. At the same time, the small lifting lugs on the flame arrester core housing are only used to lift the flame arrester core when disassembling the flame arrester, and cannot be used for the overall lifting of the flame arrester.

[0003] The Chinese patent with the announcement number CN217828689U discloses a flame arrester that is easy to hoist. The flame arrester includes a first flange, a first pipe, a second pipe, a first end cap, a second end cap, a second flange, a flame arrester core shell, a fastening component, and a lifting lug, which is arranged on both sides of the outer ends of the first pipe and the second pipe. The lifting lugs are arranged in four numbers, namely, lifting lug a, lifting lug b, lifting lug c, and lifting lug d, and a lifting hole is provided in the center of each lifting lug. The utility model installs the lifting lugs on both sides of the first pipe and the second pipe respectively, and the lifting tool can be firmly connected to the lifting lug by hanging the lifting hole, thereby greatly improving the efficiency of lifting during lifting and transportation, and the lifting through the lifting lug is firm and reliable, the flame arrester is not easy to slide, and it is easy to disassemble after the lifting is completed, which meets the requirements of the lifting operation, significantly improves its safety, and eliminates the safety hazards of the high-altitude lifting operation. The flame arrester that is easy to hoist in the application is hoisted by the lifting lug, but after being hung on the lifting lug by a hook, it is easy to slip on the hook when the lifting shakes.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a flame arrester which is easy to hoist.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0007] A flame arrester that is easy to hoist, comprises a flame arrester body, a hanging ear is provided on the flame arrester body, a sliding seat is vertically slidably fitted in the hanging ear, a guide component connected to the sliding seat is provided on the inner wall of the hanging ear, two sliding blocks are elastically slidably fitted towards each other in the sliding seat, two limit plates are rotatably fitted on the hanging ear, one end of the limit plate is hinged to the sliding block, a plurality of limit strips are provided on the upper side of the limit plate, and a tension spring is provided between the two sliding blocks.

[0008] Optionally, the guide assembly includes a guide cylinder fixed in the hanging ear and a guide rod fixed on the bottom surface of the sliding seat. One end of the guide rod slides in the guide cylinder. The guide rod is a polygonal column structure. The guide cylinder has a polygonal cylinder structure, which makes it easy for the guide rod to slide in the guide cylinder to guide the sliding seat.

[0009] Optionally, a T-shaped groove is provided on the upper side of the sliding seat, and a T-shaped block structure is provided on the upper side of the sliding block. The sliding block is slidably fitted in the T-shaped groove, so that the sliding block is guided to slide through the T-shaped groove.

[0010] Optionally, a through hole corresponding to the limit plate is provided on one side of the hanging ear, and the middle part of the limit plate rotatably fits in the through hole. An opening is provided on the upper side of the slider, and one end of the limit plate rotatably fits in the opening. Bearings corresponding to the limit plate are embedded on the opposite sides of the hanging ear, and a rotating shaft passing through the limit plate is fixed between two adjacent bearings, so as to improve the stability of the rotation of the limit plate through the bearings and the rotating shaft.

[0011] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0012] By squeezing the two limit plates, the distance between one end of the two limit plates in the hanging ear is increased, and then the hook is hung in the hanging ear. Then the limit plate is loosened, and the tension spring pulls the two sliders to slide, driving the two limit plates to clamp the hook through the limit strips, thereby reducing the probability of the hanging ear falling from the hook, and guiding the sliding seat to slide through the guide assembly.
