Remote wireless remote control device, crane outrigger control system and method

Abstract

The invention relates to a remote wireless remote control device, a crane outrigger control system and a method thereof. The remote wireless remote control device includes: a radio signal for sending a corresponding radio signal corresponding to a crane outrigger control command, including: an encoding circuit (11) and a radio frequency transmitting circuit ( 12), the coding circuit (11) is used to convert the crane outrigger control command into a coded signal; the radio frequency transmitting circuit (12) is used to amplify the coded signal and send it to the receiver. The remote wireless remote control device of the present invention enables personnel to operate freely and effectively at any position near the crane on the ground, solves the disadvantage that the operation can only be performed in the control room, avoids the inconvenience caused by personnel going up and down the control room, and effectively reduces Labor intensity; and the way of operation on the ground can greatly improve the operating field of vision, eliminate blind spots in the field of vision, and can fully observe the movement of the horizontal outriggers and vertical cylinders, thereby improving the operational safety of the crane.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a remote wireless remote control device, a crane outrigger control system and a method. Background technique [0002] The off-road tire crane is a boom rotating crane that uses a tire-type chassis for walking. Its appearance and structure are shown in Figure 1, including the boom 1a, the control room 2a, the lower vehicle 4a and four sets of movable supports installed on the lower vehicle 4a. Legs 3a, each group of movable legs 3a are composed of horizontal legs and vertical legs. The movable legs 3a are a box-shaped structure formed by tailor welding of steel plate materials, which can be stretched back and forth in another box-shaped structure. To support the whole machine when the crane is performing operations. [0003] The movable outriggers of the off-road tire crane need to be fully extended during the lifting operation to enhance the stability of the lifting; when dr...

AI Technical Summary

Problems solved by technology

[0004] However, through observation, it is found that there are some shortcomings in the outrigger control method in the prior art. First, before performing the outrigger operation, the personnel need to enter the control room 2a from the ground, and after the outrigger operation is completed, they need to come down from the control room 2a. The control room 2a of the off-road tire crane is relatively high from the ground, and it is inconvenient to go up and down the control room 2a; secondly, because the control room 2a is located on the left side of the boom 1a, affected by the volume of the boom 1a, personnel in the control room 2a During operation, the right field of vision is limited, which is a blind spot, and the ground conditions on the right side and the extension and retraction of the outriggers cannot be observed, so there are potential safety hazards; again, due to the large number of two-way rocker switches on the control panel 5a , in order to prevent the vehicle from rolling over, the extension and retraction of the four vertical outriggers must be carried out synchronously, so it is necessary to press the four corresponding rocker switches at the same time, and the operation convenience is poor
