Abstract
The invention discloses a tool for screwing and disassembling a giant thread ring. The tool comprises a ring body, wherein a plurality of knocking keys are arranged on the upper surface of the ring body; a plurality of fixing keys are arranged on the lower surface of the ring body; and a plurality of through holes are formed on the ring body. When the tool for screwing and disassembling the giant thread ring is used, grooves corresponding to the fixing keys and screw holes corresponding to the through holes on the ring body are formed on the giant thread ring, the fixing keys of the ring body are inserted into the grooves, bolts pass through the through holes on the ring body and are matched with the screw holes, so that the ring body and the giant thread ring are connected into a whole; and the knocking keys on the ring body are knocked, so that the giant thread ring is driven by the ring body and the giant thread ring can be screwed or disassembled. The tool for screwing and disassembling the giant thread ring has a simple structure, is convenient to use, and can improve construction efficiency effectively, reduce the labor strength of constructors and ensure the personal safety of the constructors during construction.
Description
Technical field
The present invention relates to a kind of instrument, particularly a kind ofly be used for tightening and dismantle the employed instrument of huge threaded collar.
Background technology
In the production process of steam turbine, need huge threaded collar be installed on steam turbine, the volume of these huge threaded collar is very big; The diameter of thread often will reach more than 2 meters, therefore often needs bigger moment if tighten this threaded collar, but because the restriction of this huge threaded collar physical dimension; The ring wall of threaded collar is thinner relatively, lacks impetus, in the process that threaded collar is tightened, is difficult on the ring wall to exert oneself; So rundown process trouble very of present huge threaded collar; Not only need waste great amount of time and manpower, and very dangerous, accident appears easily.
Summary of the invention
To the deficiency of above-mentioned prior art, the technical problem that the present invention will solve provides a kind of simple in structure, instrument that can make things convenient for huge threaded collar to tighten.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of huge threaded collar tighten extracting tool, it comprises a ring body, the upper surface of said ring body is provided with several and knocks key, the lower surface of said ring body is provided with several retainingf keys, also is provided with several through holes on the said ring body.
Preferably, saidly knock key and said retainingf key is an overall structure.
Preferably, the said key that knocks is fixed on the said ring body through pressing plate and screw.
Preferably, the upper surface of said ring body is provided with several holes for hoist.
Technique scheme has following beneficial effect: this huge threaded collar tighten extracting tool in use; On huge threaded collar, be arranged on the ring body the corresponding groove in retainingf key position and with the corresponding screw hole of through hole; Retainingf key with ring body is inserted in the groove then; And pass through hole on the ring body through bolt and cooperate with screw hole ring body and huge threaded collar are connected as one; Through knocking the key that knocks on the ring body, make ring body drive huge threaded collar then, thereby accomplish tightening or dismantling huge threaded collar.This huge threaded collar to tighten extracting tool simple in structure, easy to use, can effectively improve the efficient of construction, reduce workmen's labour intensity, and can in work progress, guarantee workmen's personal safety.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of specification, below with preferred embodiment of the present invention and conjunction with figs. specify as after.The specific embodiment of the present invention is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Fig. 1 is the structural representation that the embodiment of the invention is connected with huge threaded collar.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail.
As shown in Figure 1, the extracting tool of tightening of this huge threaded collar comprises a ring body 1, and the diameter of ring body 1 should adapt with the diameter of huge threaded collar.The upper surface of ring body 1 is provided with several and knocks key 2; The lower surface of ring body 1 is provided with several retainingf key (not shown), knocks key 2, retainingf key can be an overall structure, during fabrication; Can several plates be passed the upper and lower surfaces of ring body 1; The part of exposing ring body 1 upper surface is knocks key 2, and the part of exposing lower surface is retainingf key, and knocking key 2 can be fixed on the ring body 1 through pressing plate 3 and screw 4.Also be provided with several through holes that are used for installing admittedly moving screw on the ring body 1 and be used for being connected the hole for hoist 7 of lifting appliance with several.
As shown in Figure 1 again; This huge threaded collar tighten extracting tool in use; At first offer several and the corresponding groove in retainingf key position at the upper surface of huge threaded collar 6, and several and the corresponding screw hole of through hole, the retainingf key with ring body 1 is inserted in the groove then; And the through hole that passes on the ring body 1 with bolt 5 cooperates with screw hole on the huge threaded collar 6, makes ring body 1 and huge threaded collar 6 be connected to become an overall structure.Then lifting bolt is screwed in the hole for hoist 7 that is provided with on the ring body 1; And winch to the installation site to ring body 1 with huge threaded collar 6 with lifting appliance, and then on the screw thread of huge threaded collar 6, be coated with and lubricatedly anti-ly sting agent, knock key 2 on the ring body 1 that hits with a hammer then; Making ring body 1 drive huge threaded collar 6 rotates together; Till tightening, at last ring body 1 is removed from huge threaded collar 6, and hung out the rundown process that can accomplish rectangular thread ring 6 with lifting device.
When the dismounting threaded collar; Still adopt above-mentioned steps, at first ring body 1 is fixed on the huge threaded collar 6, hits with a hammer then oppositely to knock to knock key 2 on the ring body 1; Make ring body 1 with huge threaded collar 6 backward rotation; Get loose until huge threaded collar 6, with lifting appliance ring body 1 and huge threaded collar 6 one liftings are walked again, ring body 1 is separated with huge threaded collar 6 promptly accomplish unloading process at last.
This huge threaded collar to tighten extracting tool simple in structure, easy to use, can effectively improve the efficient of construction, reduce workmen's labour intensity, and can in work progress, guarantee workmen's personal safety.More than the extracting tool of tightening of the huge threaded collar that the embodiment of the invention provided has been carried out detailed introduction; For one of ordinary skill in the art; According to the thought of the embodiment of the invention, the part that on the specific embodiment and range of application, all can change, in sum; This description should not be construed as limitation of the present invention, and all any changes of making according to design philosophy of the present invention are all within protection scope of the present invention.
