Description
Technical field
The utility model relates to a kind of counterweight handing device, particularly relate to a kind of car hosit with counterweight from handing device.
Background technology
Tradition counterweight handing device is to be provided with the loading and unloading that two counterweight oil cylinders are finished counterweight by the turntable bilateral symmetry.Complex structure comparatively speaking, degree of automation is lower, and efficient is low.The counterweight oil cylinder adopts this kind arrangement to have following several point defects simultaneously: the first, and the rod chamber carrying, system pressure is relatively large; The second, let out the security of system poor reliability in oil cylinder is easy; The 3rd, piston rod head is stressed, and welding is had relatively high expectations.The total weight of counterweight is born by the turntable back segment fully simultaneously, and is higher to turntable back segment mechanical property requirements.From considering economically, now general middle large-tonnage hoisting crane all is furnished with and independently goes up car engine, traditional last car engine is a side that vertically is arranged in turntable, makes counterweight can arrange the below of turntable, so this kind counterweight handling mode is usually used in middle hoister in large tonnage; And concerning the car hosit of large-tonnage and super-tonnage the time, last car engine oad is bigger, when making a side of turntable not have enough width to make it vertically to arrange, must adjust lateral arrangement in the back lower place of turntable, therefore traditional counterweight handing device can not meet the demands.
Along with the direction of hoisting crane to large-tonnage, super-tonnage develops, the weight of the counterweight of car hosit and bulk are also in continuous increase, the volume of each parts of hoisting crane itself also can be increasing simultaneously, and the standard path strictness has limited outer cun of complete machine and weight, that is to say that car hosit will develop to the large-tonnage direction, height * wide must being limited within 4m * 3.1m rice, at first the problem that will solve is exactly how to utilize the good counterweight handing device of limited space reasonable Arrangement and counterweight and do not influence the engine installation of getting on the bus; And provide secondary elevator space mounting position.The problem that will solve is exactly how to go to improve the stressing conditions at turntable rear and increase work efficiency as far as possible in addition.Reach car load travel not overlength, not super wide, superelevation effect not, realize car load compactness, novel and beautiful, simple in structure, good manufacturability, dependable performance simultaneously.
The utility model content
Technical problem to be solved in the utility model provides a kind of space reasonable Arrangement, improves the stressing conditions at turntable rear, car load travel not overlength, not super wide, superelevation not, the car hosit of car load compactness with counterweight from handing device.
In order to solve the problems of the technologies described above, the car hosit that the utility model provides with counterweight from handing device, the rear of turntable be provided with connect otic placode with under be connected otic placode, the described otic placode that connects down is provided with normal pin, counter-balanced carriage be provided with described on be connected otic placode with under be connected cooresponding otic placode pin and the following engaging lug plate hole of go up connecting of otic placode, on described counter-balanced carriage, be provided with and the cooresponding at least 1 set of weights oil cylinder of vehicle frame, the barycenter of described counterweight oil cylinder group overlaps with the center of gravity of counter-balanced carriage and clump weight thereof as far as possible, on described counter-balanced carriage, be provided with knock hole, on vehicle frame, be provided with and the cooresponding locating piece of described knock hole.
The described connection otic placode of going up is provided with the mechanical position limitation piece.
Described going up connects the otic placode pin by the horizontal pin hydraulic oil cylinder driving.
Secondary elevator is connected with described counter-balanced carriage by bearing pin.
From handing device, form: horizontal pin oil cylinder, counter-balanced carriage, a 2-3 counterweight oil cylinder by this counterweight handing device with counterweight for the car hosit that utility model is designed.Counter-balanced carriage has mainly played carrying clump weight (clump weight is to be placed on the counter-balanced carriage), transmission power and a bonded assembly effect; Counter-balanced carriage go up to connect otic placode pin and following engaging lug plate hole respectively with turntable on be connected otic placode and time be connected otic placode is arranged in turntable by the bearing pin connection rear, the designer considers the characteristics of hommization simultaneously, top pin-and-hole adopts horizontal pin oil cylinder latch and pulls pin, and is convenient to very much simultaneously observe; Following normal pin then is to be welded in down to connect on the otic placode, interts and separates along with the rise and fall of counter-balanced carriage are automatic.Counter-balanced carriage adopts this connection arrangement form can disperse the back segment of turntable stressed.
It is exactly that entire mechanism is not walked with car that this counterweight dress lacks mechanical feature, alleviates the road weight of car load; Simultaneously the counterweight cylinder tube is installed on the counter-balanced carriage by bolt; The counterweight oil cylinder is up to carry counter-balanced carriage, by the rodless cavity oil-feed of counterweight oil cylinder, can well avoid the shortcoming of traditional counterweight oil cylinder when up carrying; In the process that the counterweight oil cylinder rises, place restrictions on the stroke of oil cylinder simultaneously by the mechanical position limitation piece; Counter-balanced carriage is the back that is connected turntable by bearing pin, like this layout mainly consider car engine can lateral arrangement below the turntable back segment, secondary elevator then is to be connected by bearing pin with counter-balanced carriage by bearing pin simultaneously, secondary elevator dress can be worked as counterweight usefulness.
The utility model is compared with traditional counterweight loading and unloading, has following characteristics:
1, whole counterweight handing device is not with car; Can alleviate car load and sail capable weight;
2, secondary elevator is not walked with car, can alleviate car load and sail capable weight;
3, in the counterweight installation process, the oil-feed of counterweight oil cylinder rodless cavity;
4, counter-balanced carriage is the rear that is arranged in turntable, can extrude more available spaces (being used to load onto car engine);
5, counterweight is installed steady, reliable, efficient;
6, electric, hydraulic efficiency pressure system is simple relatively;
7, counterweight loading and unloading dependence self hoisting crane is finished.
In sum, the utility model is a kind of space reasonable Arrangement, improve the stressing conditions at turntable rear, car load travel not overlength, not super wide, superelevation not, the car hosit of car load compactness with counterweight from handing device.
