Abstract
The utility model discloses a tool for hoisting a reducing piston of an engine. The tool comprises a spindle of which the top is provided with a lifting ring, wherein a hoisting disc which can move up and down along the spindle is arranged on the spindle; a plurality of hoisting claws which are matched with a combustion chamber of the reducing piston are hinged to the hoisting disc; and a clamping device which can clamp the hoisting claws and the inner wall of the combustion chamber is arranged on the spindle when the hoisting claws stretch into the combustion chamber of the reducing piston. The hoisting disc moves on the spindle, so that the hoisting claws stretch into the combustion chamber of the reducing piston, the hoisting claws are clamped with the reducing piston, and the lifting ring and a travelling crane are connected for hoisting. According to the hoisting tool, the process for machining a piston hoisting hole is avoided, and the condition that a wire drops from the hoisting hole and the piston drops in the hoisting process is avoided.
Description
Technical field
The utility model relates to a kind of frock that lifts engine piston, particularly relates to a kind of frock that lifts the medium speed engine reducing piston.
Background technology
When the dismounting medium speed engine extracts the piston rod group, because the medium speed engine fuselage is large, can not as high speed machine, there be turning rack fuselage can be overturn, by promoting connecting rod from crankcase side piston is taken out.The hole for hoist that utilizes at present piston head to reserve, two screws are screwed into hole for hoist after, piston is taken out in lifting again.There is following problem in this kind lifting mode: if same piston is lifted repeatedly, be easy to occur the hole for hoist running, if just occur in hoisting process, easily cause piston to fall, cause accident on duty.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of frock that lifts the driving engine reducing piston, and is safe and convenient to use, reduces accident rate.
For solving the problems of the technologies described above, the utility model comprises that the top is provided with the main shaft of suspension ring, the lifting dish that can move up and down along main shaft is installed on the main shaft, be hinged with a plurality of lifting pawls that adapt with combustion chamber reducing piston on the lifting dish, main shaft is provided with can be with the gripping mechanism of lifting pawl and Inner Wall of Combustion Chamber chucking when the lifting pawl stretches into the combustion chamber of reducing piston.
After adopting said structure, mobile lifting dish on main shaft, the lifting pawl is stretched in the combustion chamber of reducing piston, to lift pawl and reducing piston chucking, then suspension ring are connected with driving and lift, this kind hoisting fixture is not only removed the manufacturing procedure of piston hole for hoist from, and the situation that avoid that also the hole for hoist running occurs in hoisting process, causes piston to fall occurs.
Described gripping mechanism comprises the lifting dish and is fixed in the chuck of main shaft lower end, and described lifting dish is connected with spindle thread.Rotation lifting dish makes the lifting pawl stretch into the combustion chamber of reducing piston, and this moment, chuck withstood on a plurality of lifting pawls inboard, made lifting pawl and reducing piston chucking.
Described gripping mechanism comprises that also spiral shell is contained in the jam nut on the main shaft, and jam nut is positioned at the top of lifting dish.When lifting pawl and reducing piston chucking, the rotation lock nut makes it be pressed on lifting dish top, and the lifting dish is loosening when preventing from lifting, thus further chucking lifting pawl.
Be connected with a plurality of overhanging driving levers on the described jam nut, be convenient to the hand rotation jam nut.
Described lifting pawl end is set with rubber coating, prevents from lifting pawl the reducing piston Inner Wall of Combustion Chamber is scratched.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the frock of lifting driving engine reducing piston comprises that the top is provided with the main shaft 2 of suspension ring 1, the lifting dish 3 that can move up and down along main shaft 2 is installed on the main shaft 2, be hinged with a plurality of lifting pawls 6 that adapt with combustion chamber 5 reducing piston 4 on the lifting dish 3, main shaft 2 is provided with can be with the gripping mechanism of lifting pawl 6 with combustion chamber 5 inwalls chucking when lifting pawl 6 stretches into the combustion chamber 5 of reducing piston 4.Gripping mechanism in the present embodiment comprises lifting dish 3 and chuck 8, and the middle and lower part of main shaft 2 is provided with screw thread, and lifting is coiled on the thread segment that 3 spiral shells are contained in main shaft 2, and chuck 8 is fixed in main shaft 2 bottoms.Chuck 8 is the large frustum in little upper end, lower end, stretches into combustion chamber 5 angle of inclination after interior with lifting pawl 6 and adapts, thereby can better lifting pawl 6 be compressed.When lifting pawl 6 stretches into the combustion chamber 5 of reducing piston 4, be rotated down lifting dish 3 inboard of lifting pawl 6 is contacted with chuck 8, lifting pawl 6 is compressed by chuck 8, thereby make lifting pawl 6 and reducing piston 4 chuckings.Gripping mechanism also can adopt existing other frame modes, for example the lifting dish is sleeved on the main shaft, the spiral shell tight dish that is installed on the main shaft that is positioned at below the lifting dish, when the lifting dish is displaced downwardly to correct position, lifting pawl when stretching into the combustion chamber of reducing piston, the chucking dish is moved down make it be pressed on the chucking that to realize lifting pawl and reducing piston inwall on the lifting pawl.
Lifting is coiled 3 bottom surface uniform ring and is furnished with three hinge dress axles 7 in the present embodiment, the circle diameter that is formed centrally in three hinge dress axles 7 is greater than the diameter of chuck 8, be hinged with a lifting pawl 6 on each hinge dress axle 7, lifting pawl 6 can rotate to an angle around hinge dress axle 7, is convenient to lift pawl 6 and stretches into the combustion chamber 5 interior also realizations of reducing piston 4 and the chucking of reducing piston 4.Lifting pawl 6 comprises the connecting portion 61 that fixes as one and overhanging hook portion 62, connecting portion 61 is acute angle with hook portion 62 angles, connecting portion 61 upper ends are provided with and the hinge dress hole of cutting with scissors dress axle 7 and adapting, the structure of hook portion 62 conforms to the inner-cavity structure of the combustion chamber 5 of reducing piston 4, can stretch in the groove of combustion chamber 5 that reducing piston 4 combustion chambers 5 and failure-free be clamped on reducing piston 4, and be set with rubber coating in hook portion 62, prevent from lifting pawl 6 reducing piston 4 combustion chambers 5 inwalls are scratched.
Also be screwed with jam nut 9 on the main shaft 2, jam nut 9 is positioned at the top of lifting dish 3, and jam nut 9 outside faces are connected with 10, four driving levers 10 of four overhanging driving levers and evenly are periphery, and are convenient to hand rotation jam nut 9.When lifting pawl 6 tightened with reducing piston 4, rotation lock nut 9 made it be pressed on lifting and coils 3 tops, makes this frock have the stuck mechanism of Double-layer threaded, avoids getting loose phenomenon in the hoisting process, makes the driving safe in operation.
Rotate lifting dish 3 and adjust its upper-lower position on main shaft 2, lifting pawl 6 is stretched in the groove of combustion chamber 5 of reducing piston 4, continuing to rotate lifting dish 3 is stuck on the connecting portion 61 of lifting pawl 6 chuck 8, thereby make lifting pawl 6 and reducing piston 4 chuckings, rotation lock nut 9 makes it be pressed on lifting and coils 3 tops, then suspension ring 1 are connected with driving and lift, this kind hoisting fixture is not only removed the manufacturing procedure of piston hole for hoist from, and the situation that avoid that also the hole for hoist running occurs in hoisting process, causes piston to fall occurs.This frock volume is little, makes simple cost low, and is portable, easy to operate.
