Abstract
The utility model discloses a movable counterweight device for a crawler crane. The device comprises a counterweight connected with the A-shaped frame of the crawler crane, a counterweight pulling rope with one end connected with the counterweight and the other end fixed on a platform of the crawler crane, and a hydraulic oil cylinder, wherein, the hydraulic oil cylinder is arranged on the platform of the crane, and a pulley which is supported against the counterweight pulling rope is connected at the top end of the piston rod of the hydraulic oil cylinder. The utility model enables the counterweight pulling rope to drive the counterweight to swing clockwise or anticlockwise through the stretching of the piston rod so as to change the operating torque of the counterweight to the hoisted object, and the crawler crane further has different lifting capacities.
Description
Technical field
The utility model relates to crawler crane, relates in particular to the counterweight of crawler crane.
Background technology
At present, crawler crane all uses the fixed weight device both at home and abroad, the fixed weight device comprises the counterweight that is connected with crawler crane A shape frame, and one end be connected in counterweight, an other end is fixed on the counterweight stay cord on the crawler crane platform, the shortcoming of this counterweight is: make counterweight certain to the moment of hanging loading owing to counterweight can not move, and then make that the lifting load of crawler crane is certain, the use of crawler crane is restricted.
Summary of the invention
The purpose of this utility model is to provide a kind of crawler crane mobile counterweight device at the defective that background technology exists, and this counter weight device can make crawler crane have different lifting abilities.
For reaching above-mentioned main purpose, the technical scheme that the utility model adopted is:
A kind of crawler crane mobile counterweight device, comprise the counterweight that is connected with the A shape frame of crawler crane, and one end be connected in the other end of counterweight and be fixed in counterweight stay cord and hydraulic ram on the crawler crane platform, hydraulic ram is arranged on the hoisting crane platform, and the piston rod top of described hydraulic ram is connected with the pulley that leans with the counterweight stay cord.
As the further improvement of this crane mobile counterweight device, both sides, described piston rod top are provided with sheave shaft, and described pulley is two, are arranged at respectively on the sheave shaft, and described counterweight stay cord is two, and described pulley leans with the counterweight stay cord respectively.
Described mobile counterweight device comprises also and is arranged at guide rail relative on the crawler crane platform that described sheave shaft is positioned at guide rail.
Described counter weight device further comprises hoist cylinder, and described hoist cylinder is fixed in the A type frame of crawler crane, and the piston rod of hoist cylinder is connected with counterweight.
The beneficial effects of the utility model are:
1, the flexible counterweight stay cord that makes by piston rod drives counterweight cw or counter-clockwise swing, forms the mobile counterweight device, thereby changes counterweight to hanging the applied moment of loading, improves the lifting ability of crawler crane.
2, the lift action by hoist cylinder can realize that the lifting of counterweight also can be hung on counterweight on the crawler crane platform.
3, be arranged at moving of rail guidance pulley on the hoisting crane platform, make piston rod capable of expansion and contraction.
Description of drawings
Fig. 1 is the structural representation of the utility model mobile counterweight device one angle;
The specific embodiment
Further specify architectural feature of the present utility model below in conjunction with accompanying drawing.
See also Fig. 1, the utility model crawler crane mobile counterweight device comprises the counterweight 2 that is connected with the A shape frame 1 of crawler crane, one end is connected in counterweight 2 other ends and is fixed in counterweight stay cord 4 on the crawler crane platform 3, and being arranged at hydraulic ram 5 on the crawler crane platform 3, piston rod 51 tops of described hydraulic ram 5 are connected with the pulley 511 that leans with counterweight stay cord 4.Both sides, piston rod 51 top are provided with sheave shaft 512, and described pulley 511 is two, is arranged at respectively on the sheave shaft 512, and described counterweight stay cord 4 is two.Described mobile device also comprises and is arranged on the crawler crane platform 3 two relative guide rails 6, and described sheave shaft 512 is positioned at guide rail 6, and moving of guide rail 6 guide pulley 511 makes that piston rod 51 is capable of expansion and contraction.Described mobile counterweight device further comprises hoist cylinder 7, described hoist cylinder 7 is fixed in the A type frame 1 of crawler crane, the piston rod 71 of hoist cylinder 7 is connected with counterweight 2 by counterweight arm-tie 8, and the lift action by hoist cylinder 7 can realize that the lifting of counterweight 2 also can be hung on counterweight 2 on the crawler crane platform 3.
The utility model in use, hydraulic ram 5 piston rod 51 are moved to driver's cab, counterweight stay cord 4 matches with pulley 511 and makes counterweight stay cord 4 traction counterweights 2 counter-clockwise swings, and when piston rod 51 indentations of hydraulic ram 5, counterweight 2 is the cw swing under the component effect of self gravitation.Because counterweight 2 is energy cw or counter-clockwise swing under the driving of hydraulic ram 5 piston rods 51, form the mobile counterweight device, and then, change 2 pairs of applied moments of hanging loading of counterweight, improve the loading capability that hangs of crawler crane.
