Abstract
The utility model relates to a special tool for disassembly and assembly of a high-pressure heater self-tightening sealing oval man hole. A man hole disassembly tool used in the prior art needs to rely on a crane and is only suitable for a horizontal type high-pressure heater structure and not suitable for a vertical type high-pressure heater structure. The special tool comprises a bottom ring (1). The bottom ring is connected with a pull rod (2), the pull rod is connected with a round hole plate (3) with internal threads, the round hole plate is connected with a hollow threaded rod (5), the hollow threaded rod is connected with a first rotary rod (4) and connected with a connector (9) in a contact mode, a hollow rod (8) is inserted into the hollow threaded rod, a second rotary rod (6) is connected with the hollow rod, the hollow rod is connected with a pull ring (7) and fixedly connected with the connector, and the connector is connected with a man hole cover (10). The special tool is suitable for horizontal type high-pressure heaters or vertical type high-pressure heaters or equipment with self-tightening sealing oval man hole covers.
Description
technical field:
the utility model relates to a kind of high oval manhole of self-energized seal that adds and removes and installs specific purpose tool.
background technology:
high-tension apparatus manhole generally adopts elliptical manhole structure, self-fastening sealing structure, and pad adopts stainless steel graphite wound gasket sheet, and therefore, manhole cover need be in the inner side of equipment.Because equipment pressure is high and the restriction of manhole size, manhole cover is thicker, so manhole cover weight is heavier.Due to the restriction of space for maintenance, manhole cover need to be shifted out from device interior, be limited to the weight of manhole cover, by manual, cannot complete, need specific purpose tool.
current existing manhole extracting tool is only applicable to horizontal high-pressure heater, and relies on crane, and vertical high-pressure heater is inapplicable.
summary of the invention:
the purpose of this utility model is to provide a kind of for dismantling, install the instrument of self-energized seal manhole cover.
above-mentioned object realizes by following technical scheme:
a kind of high oval manhole of self-energized seal that adds removes and installs specific purpose tool, its composition comprises: base ring, described base ring is connected with pull bar, described pull bar is connected with tapped circular hole slab, described circular hole slab is connected with hollow thread bar, described hollow thread bar is connected with bull stick one, described hollow thread bar is connected with connector contact, hollow stem is to be inserted in described hollow thread bar, bull stick two is connected with described hollow stem, described hollow stem is connected with draw ring, described hollow stem is fixedly connected with described connector, described connector and manhole cover are hinged, described draw ring is connected with described manhole cover, described draw ring is by shaking hands, steel wire rope, clamp forms, described steel wire rope is through in described hollow stem.
beneficial effect of the present invention:
1. the utility model, by pulling draw ring, is realized ± 90 ° of manhole cover upsets.
the utility model does not rely on crane, by manually operating.
it is all applicable that the utility model adds oval self-energized seal manhole cover for horizontal, vertical height.
accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present utility model.
accompanying drawing 2 is top views of the present utility model.
accompanying drawing 3 is structural representations that base ring, pull bar are connected with circular hole slab.
