Connection, the hook is connected with the hoisting mechanism, the hook is used to hoist the weight, the controller is connected with the frame, the main arm, the hoisting mechanism and the turntable, the counterweight hoisting program is stored in the controller, when the counterweight hoisting program is executed Realize the counterweight hoisting method provided in this embodiment.
[0068] Among them, the constru...
Embodiment 2
[0135] This embodiment provides a counterweight lifting device 10, which can improve the installation efficiency of the counterweight.
[0136] For a brief description, reference may be made to Embodiment 1 for parts not mentioned in this embodiment.
[0137] see Figure 8 , in this embodiment, the counterweight lifting device 10 includes:
[0139] The angle acquisition module 100 is also used to compare the horizontal angle and the standard angle range.
[0140] The angle acquiring module 100 is further configured to send a second alarm message when the horizontal angle is not within the standard angle range, and control the movement of the frame so that the horizontal angle is within the standard angle range.
[0141] In the embodiment of the present invention, the angle acquiring module 100 may be used to execute step S100, step S110 and step S120.

Abstract
The invention provides a balance weight hoisting method and device and an engineeringmachine and relates to the field of engineering machines. The balance weight hoisting method comprises the steps that state information of a main arm is obtained; the winding outward releasing length of a winding mechanism is obtained; and the main arm, a revolving platform and the winding mechanism are controlled according to the state information, the winding outward releasing length and a revolving angle, and a hoisting hook hoists a balance weight to a target position on a frame. According to the balanceweight hoisting method and device and the engineeringmachine, the main arm, the revolving platform and the winding mechanism are controlled to move according to the obtained state information, the winding outward releasing length and the revolving angle, the hoisting hook can automatically hoist the balance weight to the target position on the frame, automatic hoisting of the balance weight is achieved, and the hoisting efficiency of the balance weight is improved.
Description
technical field [0001] The invention relates to the field of engineering machinery, in particular to a counterweight hoisting method, device and engineering machinery. Background technique [0002] With the process of modern industrialization, more and more large-volume, heavy-weight components and devices require construction machinery for installation, disassembly, and transfer. The counterweight is one of the core components of large-tonnage construction machinery. It functions to lift heavy objects and balance the long arm section or long-distance working conditions. It is large in size and heavy in weight. In order to facilitate the transfer of equipment and reduce transportation costs, large-tonnage construction machinery and equipment generally do not carry counterweights when transferring. The counterweight is hoisted from the transfer vehicle or the ground to the vehicle only when preparing for construction, and the counterweight is assembled to the crane equipment...
