Abstract
A disassembling method of a mixing paddle solves the difficulty of paddle disassembly when the matching surface of a locating stud, the paddle and a paddle shaft changes and the degree of injury cannot be accurately obtained by using the technical measures such as a fixing device of a magnetic drill press to fix a drilling machine, a welding bolt method, a manual hydraulic pump device to press and disassemble the paddle, etc, thereby guaranteeing that appearance and structure of the disassembled paddle cannot be damaged.
Description
Technical field
The present invention relates to a kind of method for dismounting of equipment, the method for dismounting of blade on particularly a kind of mixer that is used for energetic material preparation.
Background technology
Mixer is a kind of extraordinary chemical industry equipment that is used for the energetic material preparation, is made of mixing kettle, mixing oar and power, control system.Mixing oar is connected on the portal frame by the oar axle.Blade is the core component of mixer, is to be formed by the particular curve rotation, and the machining accuracy height costs an arm and a leg.Blade has the solid oar of rotation, and the groomed oar that rotates round solid oar is arranged, and solid oar all adopts alignment pin to be connected with the oar axle with groomed oar.
In the maintenance process of equipment, the work of most critical is the dismounting of blade, and under normal circumstances, only need use box spanner is detachable alignment pin, adopts very heavy to cooperate the blade heating just can finish dismounting then.
Owing under 50 ℃-60 ℃ temperature conditions, move for a long time, insulation water is housed in the hollow blade, the energetic material that mixes has certain corrosivity, and the factors such as abnormal running that cause of fault, damage can appear in alignment pin, cause mating surface to change, the mating surface of blade and oar axle also can change, and its degree of injury can't accurately obtain.Because all there is clear and definite specification requirement in the gap between gap, blade and the mixing kettle between the blade, if dismounting causes the blade distortion, it is overproof the gap requirement to occur, not only influences mixed effect, and can cause security incident.The blade dismounting must be carried out on mixer, and the space is narrow and small, is not easy to use main equipment and instrument.In unloading process, how not produce damage with structure to blade is apparent, be the difficult point of maintenance process.
Summary of the invention
The objective of the invention is to provide a kind of disassembling method of mixing paddle, can be implemented in the normal dismounting that can't determine to guarantee under the mixing paddle mating surface degree of injury mixing paddle, does not produce damage to blade is apparent with structure.
The object of the present invention is achieved like this: a kind of disassembling method of mixing paddle may further comprise the steps:
Preliminary step: prepare force bearing plate, dovetail groove coordinating block and blade carriage according to the size of blade, force bearing plate, dovetail groove are placed on the dovetail groove on the ram, then the blade carriage is placed under the blade;
Soak the location: alignment pin is soaked with lubricating oil;
The dismounting alignment pin;
Blade dismounting: the joint of hand-hydraulic pump installation is connected with alignment pin screw on the blade, with the copper packing sealing, suppresses for the hand-hydraulic pump installation, under blade is dismantled from paddle shaft.
By the magnetic drill press fixture paddle shaft is fixed, hole at alignment pin with less drill bit earlier, use bigger drill bit counterboring then, the aperture is enlarged, behind the counterboring alignment pin is got out, again the joint of hand-hydraulic pump installation is connected with alignment pin screw on the blade, seal with copper packing, suppress for the hand-hydraulic pump installation, from the paddle shaft dismounting down with blade.
At the inner surface weld bolt of being holed, utilize the spanner swivel bolt, in rotary course, endoporus is washed with washing oil, iron filings in the screw thread are gone out, when being rotated counterclockwise resistance when big, can turn clockwise.
Disassembling method of mixing paddle provided by the invention, fixedly rig, weld bolt method, hand-hydraulic pump installation such as suppress at technical measures by adopting the magnetic drill press fixture, the mating surface that has solved at alignment pin, blade and oar axle changes, when its degree of injury can't accurately obtain, the difficult point of blade dismounting has guaranteed that the apparent and structure of blade does not produce damage.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is blade of the present invention and blade pin schematic diagram.
The specific embodiment
The unloading process of blade is as follows:
(1) preliminary step: prepare force bearing plate, two dovetail groove coordinating blocks, blade carriage, above frock is placed on the dovetail groove on the ram, then the blade carriage is placed under the blade the middle gap that keeps 30mm.
(2) with lubricating oil alignment pin 3 was soaked two days.
(3) adopt box spanner dismounting alignment pin 3, the joint of hand-hydraulic pump installation is connected with alignment pin screw 5 on the blade 1, seal, suppress, when pressure reaches 6MPa, under blade 1 dismantled from paddle shaft 2 to the hand-hydraulic pump installation with the copper packing of 2mm.
When alignment pin 3 adopts box spanner normally to dismantle, drill bit with Φ 8mm drills through alignment pin 3 pore-formings earlier, uses the drill bit counterboring of Φ 16mm then, behind counterboring repeatedly, if the quilt of alignment pin 3 all gets out, finish the dismounting of blade by the hand-hydraulic pump installation; Do not got out fully as alignment pin 3, weld the bolt of M10 * 50 at the inner surface in the hole of being bored, utilize the spanner swivel bolt then, in the process of rotation, endoporus is washed with washing oil, iron filings in the screw thread are gone out, when being rotated counterclockwise resistance when big, the bolt that turns clockwise, the bolt band alignment pin and is spun out, after alignment pin 3 is removed, finish the dismounting of blade 1 again by the hand-hydraulic pump installation.
Dismounting finishes the apparent and structure not damaged of back blade.
Claims (3)
1. disassembling method of mixing paddle may further comprise the steps:
Preliminary step: prepare force bearing plate, dovetail groove coordinating block and blade carriage according to the size of blade, force bearing plate, dovetail groove coordinating block are placed on the dovetail groove on the ram, then the blade carriage is placed under the blade;
