Embodiment 1

[0059] see figure 1 , this embodiment provides a counterweight assembly method. The counterweight assembly method provided by this embodiment is applied to construction machinery, and is mainly used to install the counterweight from the frame to the turntable. The counterweight provided by this embodiment The mounting method can provide the efficiency of counterweight installation.

[0060] In this embodiment, the construction machine includes a turntable, a vehicle frame, a counterweight cylinder and a controller. The turntable is rotatably mounted on the vehicle frame, and the counterweight cylinder is installed on the turntable. The counterweight installation position on the frame, the counterweight oil cylinder installs the counterweight on the turntable, and the counterweight assembly method provided by this implementation is realized when the counterweight assembly control program is executed.

[0061] The construction machinery can be excavators, cranes, shovels, compa...

Embodiment 2

[0119] This embodiment provides a counterweight assembly device 10, which can improve the counterweight assembly efficiency.

[0120] For brief description, for the parts not mentioned in this embodiment, reference may be made to Embodiment 1.

[0121] see Figure 7 , in this embodiment, the counterweight assembly device 10 includes:

[0122] The master arm module 100 is configured to acquire real-time status information of the master arm. Wherein, the status information includes the length of the main arm and the angle of the main arm.

Abstract

The invention provides a counterweight assembling method and device and engineering mechanism, and relates to the field of engineering mechanism. The counterweight assembling method comprises the following steps: acquiring a rotation angle of a counterweight oil cylinder on a rotary table relative to a preset counterweight mounting position on a frame; and controlling the rotary table to rotate and controlling the counterweight oil cylinder to stretch according to the rotation angle, so that the counterweight oil cylinder rotates to the position above the preset counterweight mounting positionalong with the rotary table, and the counterweight oil cylinder is used for mounting a counterweight on the rotary table. According to the counterweight assembling method and device, the rotary tableis controlled to rotate through the acquired rotation angle of the counterweight oil cylinder on the rotary table relative to the preset counterweight mounting position, so that the counterweight oilcylinder rotates to the position above the preset counterweight mounting position and the counterweight is mounted on the rotary table. The process is automatically executed, and the efficiency in the counterweight mounting process is improved.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a counterweight assembly 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...
