Abstract
Description
Technical Field
[0001] The utility model relates to a flange device used for an equipment inspection hole. Background Art
[0002] In the oil refining and chemical industries, a large number of towers, containers, reactors and other equipment are used. These equipment are equipped with inspection holes, and the inspection holes are equipped with flange devices. The flange devices include flanges and flange covers (i.e., flange blind plates). The flange is welded to the inspection hole, and the flange and flange cover are connected with bolts. There are sealing gaskets between the flanges and flange covers. When the medium in the equipment is a high-temperature and high-pressure medium, it is very dangerous to remove the flange cover, because once the bolts are loose or there is an error in operation, the flange cover may burst out (i.e., bounce open), causing personal injury to the construction personnel. In the case of large size and weight of the flange cover, once the bolts are dislodged during the removal and installation of the flange cover, it is very easy to cause the flange cover to fall and injure the construction personnel. Summary of the invention
[0003] The utility model aims to provide a flange device for equipment inspection holes, so as to solve the problem that the flange cover of the existing flange device for equipment inspection holes bursts out or falls off, which may endanger construction workers.
[0004] In order to solve the above problems, the technical solution adopted by the utility model is: a flange device for an equipment inspection hole, provided with a flange and a flange cover, characterized in that: the flange device for the equipment inspection hole is also provided with a rotating bracket, a rope and a sleeve, the sleeve is fixed on the equipment, the rotating bracket includes a rotating bracket vertical rod and a rotating bracket hanging rod, one end of the rotating bracket hanging rod is connected to the upper part of the rotating bracket vertical rod, the rotating bracket vertical rod passes through the sleeve, a rotating pair is formed between the rotating bracket vertical rod and the sleeve, and the rotating bracket vertical rod is supported by the sleeve, and the flange cover is suspended on the rotating bracket hanging rod by a rope.
[0005] The above device is further characterized in that 3 to 5 sleeves are arranged in the vertical direction, the lowest sleeve is provided with a bottom plate, and the bottom of the vertical rod of the rotating bracket is supported on the bottom plate.
[0006] The above device is further characterized in that the rotating bracket hanging rod is arranged horizontally.
[0007] The use of the utility model has the following beneficial effects: (1) When disassembling the flange cover, if the bolts connecting the flange and the flange cover are loose or there is an error in operation and the flange cover pops out, because the flange cover is constrained by the rope and the rotating bracket, the distance the flange cover pops out can be greatly reduced, thereby avoiding personal injury to the construction personnel. If the bolts fall out during the disassembly and installation of the flange cover, because the flange cover is constrained by the rope and the rotating bracket, the flange cover will not fall and injure the construction personnel. (2) The flange cover is suspended on the hanging rod of the rotating bracket by a rope, and the weight of the flange cover is borne by the rope and the rotating bracket, not by the construction personnel. Therefore, manpower can be saved when disassembling, installing and moving the flange cover.
[0008] The utility model can be used on equipment such as towers, containers, reactors, etc. in industries such as oil refining and chemical engineering.
[0009] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementations. The accompanying drawings and specific implementations do not limit the scope of protection claimed by the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 The utility model is a schematic diagram of a flange device used for an equipment inspection hole. Figure 1 The device is also shown.
[0011] Figure 1 The reference numerals in the figure indicate: 1-flange; 2-rotating bracket; 3-rope; 4-sleeve; 5-flange cover; 6-equipment; 7-inspection hole. DETAILED DESCRIPTION
[0012] See also Figure 1 The utility model discloses a flange device for an equipment inspection hole (referred to as the device for short) provided with a flange 1, a flange cover 5, a rotating bracket 2, a rope 3 and a sleeve 4. The flange 1 is welded to the inspection hole 7 on the equipment 6, and the sleeve 4 is welded to the equipment 6. The equipment 6 refers to a tower, a container, a reactor, etc. in the oil refining, chemical and other industries. The rotating bracket 2 includes a rotating bracket vertical rod and a rotating bracket hanging rod, and one end of the rotating bracket hanging rod is connected to the upper part of the rotating bracket vertical rod. The rotating bracket vertical rod passes through the sleeve 4, and a rotating pair is formed between the rotating bracket vertical rod and the sleeve 4, and the rotating bracket vertical rod is supported by the sleeve 4. The flange cover 5 is hung on the rotating bracket hanging rod by the rope 3.
[0013] Generally, 3 to 5 sleeves 4 are arranged in the vertical direction. The lowest sleeve 4 is provided with a bottom plate, and the bottom of the vertical rod of the rotating bracket is supported on the bottom plate. The rotating bracket hanging rod is generally arranged horizontally, and the overall shape of the rotating bracket 2 is L-shaped. The vertical rod of the rotating bracket is a straight rod with a circular cross section, and the sleeve 4 is cylindrical.
[0014] The vertical rod of the rotating bracket can rotate relative to the sleeve 4 to rotate the rotating bracket 2, so that the flange cover 5 is in a position connected to the flange 1 (not shown), or the flange cover 5 is removed and is away from the flange 1 (such as Figure 1 shown). Figure 1 In the figure, the arrow without a reference numeral indicates the rotation direction of the vertical rod of the rotating bracket.
[0015] Figure 1 The device of the invention shown includes all components except the device 6 and the inspection hole 7.
[0016] When disassembling the flange cover 5, if the bolts connecting the flange 1 and the flange cover 5 are loose or there is an error in operation and the flange cover 5 pops out, because the flange cover 5 is constrained by the rope 3 and the rotating bracket 2, the distance of the flange cover 5 popping out can be greatly reduced to avoid personal injury to the construction personnel. If the bolts are disengaged during the disassembly and installation of the flange cover 5, because the flange cover 5 is constrained by the rope 3 and the rotating bracket 2, the flange cover 5 will not fall and injure the construction personnel.
[0017] It is understood that the present invention is described by some specific embodiments. Those skilled in the art know that various changes or equivalent substitutions can be made to these specific embodiments to adapt to specific circumstances without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited by the disclosed specific embodiments. All changes or equivalent substitutions that fall within the scope of the claims of this application belong to the scope of protection of the present invention.
