Abstract
The utility model discloses a counterweight lifting mechanism for autocranes, which comprises a crane turntable (7). A counterweight oil cylinder installation base (2) is arranged under the rear section of the crane turntable (7) and provided with a counterweight lifting oil cylinder (1). An movable counterweight (3) is provided with a lifting hole (5) matched with the counterweight lifting oil cylinder (1). A base hinge ear (6) is arranged on the counterweight oil cylinder installation base (2); and a counterweight hinge ear (4) which is matched with the base hinge ear (6) is arranged on the movable counterweight (3). The utility model relates to a counterweight lifting mechanism of an autocrane, which can improve the stability of cranes and decrease the running deadweight of cranes. The whole mechanism can be manufactured at low cost, operated in short time, and loaded and unloaded quickly; moreover, the mechanism is safe and reliable. Thus, the counterweight lifting mechanism can be conveniently and simply applied to cranes, the counterweight of which is changed into movable counterweights from fixed counterweights.
Description
Technical field
The utility model relates to a kind of hoisting crane counter weight device, particularly relates to a kind of hoisting crane with modular counterweight bont.
Background technology
Counterweight is the main components of hoisting crane, and the weight of counterweight has very big influence to the stability and the lifting performance of hoisting crane.The car hosit of little tonnage adopts the version of fixed weight, owing to be subjected to the restriction of complete machine motoring condition deadweight, the weight of counterweight is limited, thereby the stability that has limited hoisting crane further promotes.
The utility model content
Technical problem to be solved in the utility model provides a kind of stability that improves hoisting crane, alleviates the car hosit counterweight lift system of the deadweight of travelling of hoisting crane.
In order to solve the problems of the technologies described above, the hoisting crane counter weight device that the utility model provides, comprise rotating platform of crane, counterweight oil cylinder mounting seat is installed below described rotating platform of crane back segment, on described counterweight oil cylinder mounting seat, the counterweight elevating ram is installed, establish on the moving counterweight and the cooresponding lifting of described counterweight elevating ram hole, on described counterweight oil cylinder mounting seat, be provided with base hinge ear, establish on the described moving counterweight and the cooresponding counterweight hinge of described base hinge ear ear.
Described counterweight elevating ram adopts asymmetric layout, and the center of gravity after the intersection point of promptly described counterweight elevating ram connection lead and rotating platform of crane line of centers and described moving counterweight are in place is on same vertical curve.
Counterweight oil cylinder mounting seat is the body structure of modular design.
Adopt the car hosit counterweight lift system of technique scheme, counterweight lift piston bar is stretched out, link to each other with lifting hole on the moving counterweight then, withdrawal piston rod to counterweight reaches under the oil cylinder mounting seat, again the counterweight on moving counterweight hinge ear is linked to each other with base hinge ear on the oil cylinder mounting seat, can fix moving counterweight.
The utility model counter weight device mainly contains following effect: the counterweight lift system adopts asymmetric oil cylinder design, can install this mechanism additional under the situation that does not change former turntable structure, and this mechanism and other elements is not also interfered.The oil cylinder mounting seat is a body structure, has bigger bearing capacity, can satisfy the requirement of little tonnage hoisting crane to counterweight widely.
In sum, the utility model is a kind of stability that improves hoisting crane, alleviates the car hosit counterweight lift system of the deadweight of travelling of hoisting crane.Whole device low cost of manufacture, the manipulation process time is short, and loading and unloading are quick, and are safe and reliable.Can be used for fixing the hoisting crane that counterweight changes moving counterweight into convenient and simplely.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the utility model counter weight device scheme drawing;
Fig. 2 is that oil cylinder of the present utility model is arranged birds-eye view.
The specific embodiment
Referring to Fig. 1 and Fig. 2, counterweight oil cylinder mounting seat 2 is installed below rotating platform of crane 7 back segments, counterweight oil cylinder mounting seat 2 is body structures of modular design, on counterweight oil cylinder mounting seat 2, counterweight elevating ram 1 is installed, counterweight elevating ram 1 adopts asymmetric layout, be that center of gravity after the intersection point of counterweight elevating ram 1 connection lead and rotating platform of crane 7 line of centerss and moving counterweight 3 are in place is on same vertical curve, be that center of gravity after counterweight elevating ram 1 is in place with moving counterweight 3 is that symmetric points are installed on the counterweight oil cylinder mounting seat 2, establish on the moving counterweight 3 and counterweight elevating ram 1 cooresponding lifting hole 5, on counterweight oil cylinder mounting seat 2, be provided with base hinge ear 6, establish on the moving counterweight 3 and base hinge ear 6 cooresponding counterweight hinge ears 4.
Referring to Fig. 1 and Fig. 2, counterweight oil cylinder mounting seat 2 is welded on the bottom of the back segment of rotating platform of crane 7, counterweight elevating ram 1 asymmetric layout can be avoided the parts of lifting mechanism.It is hinged with the lifting hole 5 of moving counterweight 2 that counterweight elevating ram 1 piston rod stretches out the back, regain the piston rod of counterweight elevating ram 1, when counterweight oil cylinder mounting seat 2 lower planes are run on plane on the moving counterweight 3, that the counterweight hinge ear 4 of moving counterweight 3 is hinged with the base hinge ear 6 on the counterweight oil cylinder mounting seat 2.The dismounting inverse operation of moving counterweight 3.
Claims (2)
1, a kind of car hosit counterweight lift system, comprise rotating platform of crane (7), it is characterized in that: the below at described rotating platform of crane (7) back segment is equipped with counterweight oil cylinder mounting seat (2), counterweight elevating ram (1) is installed on described counterweight oil cylinder mounting seat (2), establish on the moving counterweight (3) and described counterweight elevating ram (1) cooresponding lifting hole (5), on described counterweight oil cylinder mounting seat (2), be provided with base hinge ear (6), establish on the described moving counterweight (3) and the cooresponding counterweight hinge of described base hinge ear (6) ear (4).
2, car hosit counterweight lift system according to claim 1, it is characterized in that: described counterweight elevating ram (1) adopts asymmetric layout, and the center of gravity after the intersection point of promptly described counterweight elevating ram (1) connection lead and rotating platform of crane (7) line of centers and described moving counterweight (3) are in place is on same vertical curve.
