Abstract
The utility model discloses a movable counterweight installation mechanism for cranes, which comprises a movable counterweight (8), an installation base (9) which is arranged on the rear section of a turntable (10), as well as a counterweight lifting oil cylinder (11). The installation base (9) is provided with a fixed bushing (1) and a fixed hinge ear (2); and a chock block (3) which is matched with the movable counterweight (8) is installed on the installation base (9) by a flexible installation bracket (7). The movable counterweight (8) is provided with a counterweight hinge ear (5) which is matched with the fixed hinge ear (2), and also provided with a guide base (4) which is matched with the fixed bushing (1). The utility model relates to a movable counterweight installation mechanism which can conveniently install a movable counterweight on the turntable; and due to the movable counterweight installation mechanism, shock or instability caused by either the running or the hoisting of the crane can not damage the counterweight oil cylinder seriously; moreover, the counterweight of the installation mechanism basically can not shake.
Description
Technical field
The utility model relates to a kind of hoisting crane moving counterweight installing mechanism, particularly relate to a kind of hoisting crane with can shock resistance, the moving counterweight installing mechanism of protection counterweight elevating ram.
Background technology
Moving counterweight is the main components of hoisting crane, and general activity counterweight impact resistance after installation is not strong, and counterweight is rocked easily, and then the counterweight elevating ram is produced bigger damage.And fixed weight changes the hoisting crane of moving counterweight, sometimes needs the moving counterweight band is travelled at the turntable rear portion, like this counterweight installing mechanism has been proposed higher requirement.
The utility model content
Technical problem to be solved in the utility model provide a kind of can make moving counterweight be installed in the turntable rear portion easily after, no matter be that hoisting operation or car load travel, impact, steadily all the counterweight oil cylinder produced bigger damage, the hoisting crane that counterweight is not rocked basically moving counterweight installing mechanism.
In order to solve the problems of the technologies described above, the hoisting crane that the utility model provides moving counterweight installing mechanism, the mount pad and the counterweight elevating ram thereof that comprise moving counterweight and be installed in the turntable back segment, on described mount pad, be provided with fixed cover and fixing hinge ear, be installed on the described mount pad by the elastomeric mounting support with the cooresponding backing block of described moving counterweight, on described moving counterweight, be provided with and the cooresponding counterweight hinge of described fixedly hinge ear ear, on described moving counterweight, be provided with and the cooresponding guide holder of described fixed cover.
Described guide holder leading portion is that taper, back segment are cylindrical.
Adopt the hoisting crane moving counterweight installing mechanism of technique scheme, when installing, counterweight considers by cooperation to counterweight elevating ram stroke and backing block, utilize the elastic deformation of backing block support to make mechanism's tensioning, make the degree of freedom of counterweight all directions after installing to access sufficient restriction.
The utility model counter weight device mainly contains following effect:
After moving counterweight is installed in the turntable back segment, all can not Free Slosh in the vertical direction, the horizontal extent.This mechanism does not influence the smooth dismounting of moving counterweight again.
In sum, the utility model be a kind of can make moving counterweight be installed in the turntable rear portion easily after, no matter be that hoisting operation or car load travel, impact, steadily all the counterweight oil cylinder produced bigger damage, the hoisting crane that counterweight is not rocked basically moving counterweight installing mechanism.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the scheme drawing of the utility model counterweight installing mechanism;
The specific embodiment
Referring to accompanying drawing, at turntable 10 back segments mount pad 9 is installed, counterweight elevating ram 11 is installed on mount pad 9, on mount pad 9, be provided with fixed cover 1 and fixing hinge ear 2, be installed on the mount pad 9 by elastomeric mounting support 7 with moving counterweight 8 cooresponding backing blocks 3, be provided with on moving counterweight 8 and fixing hinge ear 2 cooresponding counterweight hinge ears 5, be provided with on moving counterweight 8 and fixed cover 1 cooresponding guide holder 4, guide holder 4 leading portions are that taper, back segment are cylindrical.
Referring to accompanying drawing, moving counterweight 8 is in the process of installing, be connected with moving counterweight 8 with the piston rod of connecting pin 6 earlier counterweight elevating ram 11, the piston rod of the counterweight of withdrawing again elevating ram 1, when retracting to a certain degree, the meeting of last plane and the backing block 3 of moving counterweight 8 are collided, the elastomeric mounting support 7 of backing block 3 has certain rigidity, the piston rod of counterweight elevating ram 1 can not be withdrawn after producing elastic deformation, but the stroke of this moment is not used up, and the elastomeric mounting support 7 of backing block 3 has slack-free trend always.Guide holder 4 is inserted in the fixed cover 1 simultaneously, and guide holder 4 leading portions are taper, and back segment is cylindrical, and the hole of its external diameter and fixed cover 1 is small free-running fit.To fix hinge ear 2 and be connected with counterweight hinge ear 5, moving counterweight 8 promptly is installed in turntable 10 rear portions more steadily.After being connected of fixing hinge ear 2 and counterweight hinge ear 5 promptly cancelled in the dismounting of moving counterweight 8, the piston rod that stretches out counterweight elevating ram 11 got final product.
Claims (2)
1, a kind of hoisting crane moving counterweight installing mechanism, the mount pad (9) and the counterweight elevating ram (11) thereof that comprise moving counterweight (8) and be installed in turntable (10) back segment, it is characterized in that: on described mount pad (9), be provided with fixed cover (1) and fixing hinge ear (2), be installed on the described mount pad (9) by elastomeric mounting support (7) with the cooresponding backing block of described moving counterweight (8) (3), on described moving counterweight (8), be provided with and the cooresponding counterweight hinge of described fixedly hinge ear (2) ear (5), on described moving counterweight (8), be provided with and the cooresponding guide holder of described fixed cover (1) (4).
2, hoisting crane according to claim 1 moving counterweight installing mechanism is characterized in that: described guide holder (4) leading portion is that taper, back segment are cylindrical.
