Abstract
The utility model provides a detachable counter weight mounting device for an engineering machine, which comprises a lifting oil cylinder, a sleeve, and a counter weight, wherein the lifting oil cylinder is mounted at the tail part of a rotary table of the engineering machine, and the gyration radius of the lifting oil cylinder is the distance from the axis of the lifting oil cylinder to a gyration bearing; the sleeve is arranged on a main frame of the engineering machine, a sleeve column matched and connected with the lifting oil cylinder is arranged at the upper part of the sleeve, and a round tube part sleeved with the counter weight is arranged at the lower part of the sleeve; a hole is formed in the counter weight, the shape of the hole coincides with the motion track of the lifting oil cylinder, and the size of the hole is matched with the diameter of the round tube of the sleeve. The detachable counter weight mounting device has the advantages and the benefits that through the adoption of the technical scheme, when counter weight assemblies are frequently replaced, and the counter weight is mounted, quick and precise positioning and mounting can be implemented, and the working efficiency is improved.
Description
Technical field
The utility model belongs to technical field of engineering machinery, especially relates to a kind of detouchable counterweight erecting device for construction machinery and equipment.
Background technology
Engineering machinery field, the application of counterweight is extremely extensive, elevator machinery, excavation machinery and piling machinery etc. all can be applied counterweight and realize the balance of complete machine, after the counterweight that different is has completes once mounting, all no longer dismountings in work and transition transportation, and some machinery is considered complete vehicle weight, conversion working condition and convenient transportation etc., counterweight is often made detouchable, and thing followed problem is exactly that the large and work efficiency of the work capacity brought of the frequent mounting or dismounting of counterweight is lower etc.Take car hosit as example, because working condition is many, combinations of weights is more.
In prior art, the lifting of counterweight realizes by whipline, and counterweight with conventionally make bolt being connected of turntable and connect, waste time and energy changing during combinations of weights like this, and bolt is difficult to accurate location, work efficiency is low and have a potential safety hazard.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of detouchable counterweight erecting device for construction machinery and equipment, is especially applicable to the construction machinery and equipment of the frequent mounting or dismounting of needs counterweight.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
For the detouchable counterweight erecting device of construction machinery and equipment, comprise
Elevating ram, is arranged on the turntable afterbody of construction machinery and equipment, and radius of turn is the distance of elevating ram axis to pivoting support;
Sleeve, is arranged on the vehicle frame of construction machinery and equipment, and its top is the sleeve cylinder being connected with elevating ram, and bottom is the pipe part being socketed with counterweight;
Counterweight, has hole on it, the shape in described hole and the path of motion of elevating ram are wanted to coincide, and the diameter of the size in hole and the pipe of sleeve matches.
Further, the end of described lift piston bar is stepped shaft, and the sleeve cylinder of sleeve is ladder end face, and stepped shaft matches with ladder end face.
Further, the position in the hole of described counterweight is positioned on the straight line at counterweight center of gravity place.
Further, described pipe part is followed successively by the first disk, the first pipe, the second disk and the second pipe that are connected with sleeve cylinder from top to bottom.
Further, steel plate cutting forming is filled or directly adopted to described counterweight after adopting cast form or welding forming.
Further, described sleeve is to adopt the cylinder of different-diameter to be welded
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, when frequent replacing combinations of weights and installation counterweight, can realize and locate fast and accurately and install, increase work efficiency.

The specific embodiment
As shown in Figures 1 to 3:
Detouchable counterweight erecting device for construction machinery and equipment of the present utility model, comprises elevating ram 7, counterweight 6 and sleeve,
Sleeve, be arranged on the vehicle frame of construction machinery and equipment, its top is the sleeve cylinder 1 being connected with elevating ram 7, bottom is the pipe part being socketed with counterweight 6, and described pipe part is followed successively by the first disk 2, the first pipe 3, the second disk 4 and the second pipe 5 that are connected with sleeve cylinder 1 from top to bottom;
The end of described elevating ram 7 piston rods is stepped shaft, and the sleeve cylinder 1 of sleeve is ladder end face, and stepped shaft matches with ladder end face.
The position in the hole of described counterweight 6 is positioned on the straight line at counterweight 6 center of gravity places.
Described counterweight 6 adopts steel plate cutting forming.
Described sleeve is to adopt the cylinder of different-diameter to be welded.
The working process of this example:
1) on the vehicle frame of construction machinery and equipment, be provided with the convex of fixed muffle, first, by counterweight 6 and sleeve socket, be located in the path of motion of elevating ram 7;
2) turntable turns round, when elevating ram 7 approaches sleeve, elevating ram 7 starts to move vertically downward, turntable continues revolution, as the direction of arrow A motion in Fig. 3, elevating ram 7 end stepped shaft are matched with the cascade ring on sleeve cylinder 1, elevating ram 7 shrinks afterwards, carry out counterweight 6 and promote, as the sense of motion of arrow B in Fig. 3;
3) counterweight 6 is promoted to after turntable base plate, and counterweight 6 is connected with bearing pin with turntable, and then elevating ram 7 declines together with sleeve, and sleeve is put on vehicle frame.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
