[0003] In the actual implementation of the above, in order to ensure the fast and effective connection process of the balance weight, the operator needs to use experience and auxiliary operation equipment to load and unload the balance weight and complete the loading and unloading of the balance weight. It can be seen that the existing balance weight installation method is self-assisted Judgment and need to add handheld devices, low cost performance and low efficiency

[0059] see Figure 4 , this embodiment provides a method for automatically loading and unloading the counterweight of construction machinery, and this embodiment takes the automatic hanging process as an example to specifically introduce the method for automatically loading and unloading the counterweight of construction machinery. The method for automatically loading and unloading the balance weight of construction machinery includes the following steps:

[0060] Step S101 , in response to the operation of the control handle of the construction machine 10 , control the rotation mechanism 15 of the construction machine 10 to rotate, and drive the counterweight tray 14 of the construction machine 10 to rotate to a first calibration angle position. Wherein, the first calibration angle position indicates that the angle between the projection of the block 16 of the vertical oil cylinder of the construction machine 10 on the counterweight tray 14 and the center of rotation of the s...

[0088] see Figure 2-Figure 4 , this embodiment provides a method for automatically loading and unloading the counterweight of construction machinery, and this embodiment specifically introduces the method for automatically loading and unloading the counterweight of construction machinery by taking the automatic unloading process as an example. The flow chart of this embodiment can refer to the first embodiment. The difference between the automatic loading and unloading method of the construction machinery counterweight in this embodiment and the first embodiment is that the initial state is different. In this embodiment, in the initial state, the balance weight has been hung up. , the clamping block 16 and the clamping slot 142 have been assembled, and the automatic unloading process of the counterweight is realized through the automatic loading and unloading method of the construction machinery counterweight in this embodiment. Only the differences between this embodiment an...

[0096] see Figure 8 , this embodiment provides a method for automatic loading and unloading of construction machinery counterweights, which, on the basis of the first embodiment and the second embodiment, further includes an angle calibration step, which is used to calibrate the first calibration angle and the second calibration angle , to determine the first calibration angle position and the second calibration angle position.

[0097] In this embodiment, the step of angle calibration is before the above step S101, which includes the following steps:

[0098] Step S201 , setting the calibration zero line of the slewing mechanism 15 .

[0099] In this embodiment, the quantitative displacement rotation angle of the rotation mechanism 15 is marked as 0, and it is confirmed that one rotation corresponds to 360°. Among them, the calibration zero line is indicated by the dotted line in the attached drawing.

[0100] Step S202 , hoisting the balance weight to be hung onto the ve...

Abstract

The invention provides an automatic mounting and demounting method and device of a counterweight of an engineering machine and the engineering machine, and relates to the field of engineering machines. The automatic mounting and demounting method of the counterweight of the engineering machine comprises the steps that by responding to the operation action of a control handle of the engineering machine, a rotary mechanism of the engineering machine is controlled to rotate, and a counterweight tray of the engineering machine is driven to rotate to a first calibrated angle position; a vertical oil cylinder is controlled to stretch to a first preset position; the rotary mechanism is controlled to rotate, the counterweight tray is driven to rotate to a second calibrated angle position from thefirst calibrated angle position; and the vertical oil cylinder is controlled to contract to a second preset position. According to the automatic mounting and demounting method and device of the counterweight of the engineering machine and the engineering machine, the rotary mechanism of the engineering machine, the vertical oil cylinder and pre-calibrated calibrated position information are utilized, automatic connection of a clamping block and a clamping groove of the counterweight tray is achieved, and automatic lifting and descending of the counterweight are achieved. Thus, assistance of manpower and handheld equipment is reduced, efficiency is higher, and the operation process is convenient.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a method and device for automatically loading and unloading a balance weight of an engineering machinery, and an engineering machinery. Background technique [0002] At present, in the construction machinery industry, large and medium-sized hoisting equipment with counterweight self-loading and unloading functions are widely used in various handling and construction industries. The self-loading and unloading of the balance weight refers to the fast, accurate and stable installation of the balance weight by using the technology and function of the equipment's own loading and unloading of the balance weight without the assistance of other vehicles or hoisting tools. Its actuator is mainly realized through the cooperation of vertical ground and horizontal oil cylinders and the positioning mechanism of the frame itself. Among them, the vertical oil tank is used to control the lif...
