Abstract
The utility model discloses a slidable turntable balance weight device of a crawler crane. The slidable turntable balance weight device comprises a balance weight block, wherein the balance weight block is connected with a balance weight tray; the balance weight tray is connected with a sliding trolley; the sliding trolley is pressed on a slide way; the slide way is connected with a platform box type mechanism; and the sliding trolley is connected with a telescopic mechanism. The slidable turntable balance weight device has a simple structure and is easy to mount, and the center of gravity of the entire machine can change on the premise of guaranteeing that the structure of the crawler crane is kept to be optimal, so that the stability of the entire machine is effectively improved, various working condition requirements can be adapted, and the safety in operation of the crane is guaranteed.
Description
Technical field
The utility model relates to a kind of counter weight device, is specifically related to a kind of packaged type counter weight device that is used on the crawler crane.
Background technology
The widespread usage of hydraulic crawler crane in China's large and medium-sized projects in recent years; Particularly the wind-powered electricity generation installation project progressively heats up; The special operating mode configuration of wind-powered electricity generation is had higher requirement to the stability of crawler crane; In the large-tonnage crawler crane how well solve the requirement that can adapt to multiple complex working condition, can satisfy transportation again and from the problem that arm is installed, this is with regard to the center of gravity that relates to complete machine and the problem of balancing torque.Use for packaged type turntable counterweight is existing in the industry, but mostly version is complicated, process for machining and manufacturing is loaded down with trivial details and cost is expensive.The most important thing is to install very inconvenience, machine gravity control is very complicated.
The utility model content
The technical matters that the utility model will solve is that the packaged type counter weight construction on the existing crawler crane is complicated, the installation trouble, and a kind of simple in structure, easy crawler crane slip formula turntable counter weight device of installation is provided.
The technical scheme of the utility model realizes in the following manner: a kind of crawler crane slip formula turntable counter weight device; Comprise clump weight; Clump weight links to each other with the counterweight pallet, and the counterweight pallet links to each other with the slippage dolly, and the slippage dolly is pressed on the slideway; Slideway links to each other with the platform box type mechanism, and the slippage dolly links to each other with telescoping mechanism.
Said telescoping mechanism is a push cylinder.
The utility model is simple in structure, installation is simple and easy; Structure guaranteeing crawler crane keeps under the optimized prerequisite, makes machine gravity to change, thereby effectively improves the stability of complete machine; Reach the requirement of self adaptation various working, guarantee the safety of the operation of hoisting crane.

The specific embodiment
Shown in accompanying drawing, a kind of crawler crane slip formula turntable counter weight device comprises clump weight 6; Clump weight 6 links to each other with counterweight pallet 5, and counterweight pallet 5 links to each other with slippage dolly 2, and slippage dolly 2 is pressed on the slideway 3; Slideway 3 links to each other with platform box type mechanism 4, and slippage dolly 2 links to each other with telescoping mechanism.Wherein, be connected through bearing pin between slippage dolly 2 and the counterweight pallet 5, slideway 3 links to each other with platform box type mechanism 4 through bolt.
Said telescoping mechanism is a push cylinder 1, and push cylinder 1 one ends are hinged on the slippage dolly 2, the other end and main platform are hinged and connected.
The working process of the utility model is following: the push cylinder 1 flexible front and back slippage that drives slippage dolly 2, slippage dolly 2 drive counterweight pallets 5 realization clump weights 6; Thereby changed the center of gravity of tracked machine; Realize the balance of the positive negative moment of complete machine, effectively improve the stability of complete machine.
