Description
Technical field
The utility model belongs to Casting Equipment field, is related to the maintenance door of the safe and efficient opening and closing of one of moulding machine.
Background technique
In Casting Equipment field, need whether to run well inside running check gas tank, under normal circumstances, inside gas tank
It is fully sealed, if you need to check inner case, maintenance door need to be opened, people enters inside gas tank.So required gas tank opening
Larger, this will lead to, and maintenance door is equally larger, and weight is overhauled up to tens kilograms even up to a hundred kilograms if being opened with manpower merely
Door, it is time-consuming and laborious.
Summary of the invention
Problem to be solved in the utility model is to overcome the deficiencies of the prior art and provide that a kind of structure is simple, stablizes
Reliably, the maintenance door of low-cost safe and efficient opening and closing.
To achieve the above object, the technical solution that the utility model is taken are as follows:
A kind of maintenance door of safe and efficient opening and closing, the maintenance door board including opposite opened are symmetrically welded on the top of door-plate
There are two platform sling, platform sling is connect by eyelet bolt with step pin axle, and the step pin axle right end is blocked with step, and left end is used
Split pin A is blocked, to prevent step pin axle or so from deviating from；Wear the top by arc bracket, arc in the eyelet bolt top
Bracket lower part is fixed by bend pipe, and bent plate is welded in gas tank side, and the lower end of arc bracket is blocked with split pin B, prevent its to
Upper abjection；The arc bracket is welded with step cutting pattern by lower part, it is made to be stuck in bent plate top, prevents it from falling by gravity
It falls；The arc bracket top, which mills, puts down, and collar nut is by the screw thread of eyelet bolt loaded in the plane milled after putting down；The arc
Gasket is housed between bracket step lower part and bent plate top.
Preferably, the gasket is wear-resistant material.
Preferably, the pin shaft state is marked as GB/T 882.
The utility model has a significant advantages and beneficial effects compared with prior art: the utility model it is safe and efficient
The maintenance door of opening and closing is not required to provide the power such as cylinder oil cylinder motor, saves cost, securely and reliably, and structure is simple, design department
It learns rationally, is easy to the open and close of maintenance door.
Detailed description of the invention
Fig. 1 is the structural front view of the utility model；
Fig. 2 is the left view of the utility model.
Wherein: 1, overhauling door board；2, platform sling；3, step pin axle；4, split pin A；5, eyelet bolt；6, collar nut；
7, arc bracket；8, gasket；9, bent plate；10, split pin B, 11- gas tank.
Specific embodiment
Below in conjunction with attached drawing and preferred embodiment, to according to specific embodiment provided by the utility model, structure, feature
And its effect, detailed description is as follows.
As illustrated in figs. 1 and 2, a kind of maintenance door of safe and efficient opening and closing, the maintenance door board 1 including opposite opened, in door
The top of plate 1 is symmetrically welded there are two platform sling 2, and platform sling 2 is connect by eyelet bolt 5 with step pin axle 3, the step pin axle
3 right ends are blocked with step, and left end is blocked with split pin A4, to prevent step pin axle 3 or so from deviating from；On the eyelet bolt 5
Portion is worn by the top of arc bracket 7, and 7 lower part of arc bracket is fixed by bend pipe 9, and bent plate 9 is welded in 11 side of gas tank, arc branch
The lower end of frame 7 is blocked with split pin B10, prevents its prolapse upwards；The arc bracket 7 is welded with step cutting pattern by lower part, makes it
It is stuck in 9 top of bent plate, prevents it from falling by gravity；7 top of the arc bracket milling is flat, and collar nut 6 passes through movable joint
The screw thread of bolt 5 is loaded in the plane milled after putting down；Gasket 8 is housed between the 7 step lower part of arc bracket and 9 top of bent plate.
The gasket 8 is wear-resistant material.
The step pin axle state is marked as GB/T 882.
The working principle of the utility model is: under normal conditions, be bolted between maintenance door and gas tank, when needing to open
Maintenance door when checking gas tank inside, unclamps bolt, and collar nut of holding with a firm grip does maintenance door around the arc bracket other end
Rotation, only moves horizontally, and is not necessarily in vertical direction to power, convenient and time saving and energy saving.The utility model is not required to provide cylinder oil
The power such as cylinder motor save cost, and securely and reliably, and structure is simple, and design is scientific and reasonable, are easy to unlatching and the pass of maintenance door
It closes.
One embodiment of the utility model is described in detail above, but the content is only the utility model
Preferred embodiment should not be considered as limiting the scope of the present invention.It is all to be made according to application scope of the utility model
All the changes and improvements etc., should still belong within the patent covering scope of the utility model.
