Ground jack operating control device of wheel type engineering machinery chassis

Abstract

The invention discloses a ground jack operating control device of a wheel type engineering machinery chassis which is used for outputting switching signals to an operational controller and comprises acontrol box and cables, wherein, the control box is provided with a control switch which is used for controlling the operation of the ground jack; switching signals are output when the control switchis operated; and the cables are used for outputting the switching signals from the control box to the operational controller; optimally, the cables are spring cables in particular. Compared with theprior art, in workplaces with narrow area and complex ground conditions, operators can leave the operational platform and control the operation of the ground jack by holding the control box in hand; and based on the invention, operators can stand at either side of the car body to monitor at real time and can stop the motion of the ground jack by releasing the push button switch on the control boxwhen a danger is discovered, thus improving the safety of operational control of the ground jack.

Description

technical field [0001] The invention relates to the control technology of wheeled construction machinery, in particular to an outrigger operation control device for the chassis of the wheeled construction machinery. Background technique [0002] During load operation, the chassis of wheeled construction machinery usually needs to extend outriggers to improve working stability, such as wheeled cranes, elevating fire trucks and so on. As an important part of fire-fighting equipment, the fire-fighting market has higher requirements for elevating fire trucks. With the development of high-rise buildings in cities, there are higher requirements for the stability of elevating fire trucks. Existing elevating fire trucks are mainly composed of two main parts: chassis, lifting arm frame, working platform or water cannon; wherein, the lifting arm frame is installed on the chassis, and the working platform or water cannon is installed on the front end of the arm frame. The extension an...

Problems solved by technology

[0004] The horizontal outrigger and vertical outrigger operating devices of existing elevating fire trucks are usually centrally arranged at the rear operating platform of the vehicle body. Since the vehicle body is wide and high, the operator performs outrigger control operations on the operating platform. , there is a problem that the movement status of the front and rear outriggers cannot be seen

For a workplace with a wide site and a solid ground, the impact of the above problems is not very prominent; however, for a workplace with a narrow site and complex ground conditions, the control requirements for the extension of the outriggers are different, for example, horizontal The outriggers cannot be fully extended, the vertical outriggers cannot sink, etc. Therefore, based on the existing outrigger operating device, the operator cannot monitor the movement status of the outriggers. Usually, two people are required to cooperate to complete the operation and control of the outriggers, so as to improve Safety of outrigger operation controls, operations are restricted
