Embodiment Construction

[0017] figure 1 Also shown is a work vehicle in the form of a demolition robot 1 which, according to the invention, is equipped with means for generating and diffusing a liquid mist in the work area where the tool is used. The apparatus includes a source of pressurized water and a source of pressurized air, respectively, which may suitably be obtained from an external network on the job site on which the work vehicle operates. In another embodiment, the work vehicle 1 must be able to accommodate suitable internal sources that can provide pressurized water and pressurized air, respectively.

[0018] An operator 2 (machine operator) walks beside the work vehicle 1 and wirelessly controls the work vehicle 1 via a remote control device 4 including a transmitter / receiver unit. The chassis comprising a bracket with a top bracket 6 and a bottom bracket 7 is generally designated 5 . The top bracket 6 is rotatably mounted on the bottom bracket 7 for swinging in a horizontal plane. T...

Abstract

The invention relates to a work vehicle (1) comprising: an operable arm (10) adapted to manipulate a tool (A-D) fastened to a free end of the arm; a control unit (4) for controlling the work vehicle (1); a dust control system arranged to dispense water mist for the purpose of retaining dust generated when the tool is used. In order to effectively control dust, the dust control system comprises: a source of pressurized air (31) and a source of pressurized water (21); an air duct (33) arranged for a tool (A-D), through which air flow from the pressurized air source (31) can be conveyed; and an injection nozzle (26) that directs the air flow in the air duct (33), with which water from the pressure water source (21) can be injected into the air flow for atomizing the water into droplets that together with the air flow form a water mist, an air duct arranged for the tool (A-D) is directed such that the droplets form a water mist (36) around the tool.

Description

technical field [0001] The present invention relates to a tool-carrying work vehicle with a device for dust control in connection with demolition work according to the preamble of claim 1 . The invention also relates to a method according to the preamble of claim 10 for limiting dust formation in connection with demolition work with a work vehicle carrying a tool. Background technique [0002] A work vehicle, such as a sabotage or demolition robotic demolition, is a remotely controlled work machine traveling on a track that can carry various types of tools for various types of work tasks at the free ends of the operable arms. As an example of a tool, mention may be made of a chisel hammer for demolition and demolition work. An operator typically walks beside the machine and controls various movements of the machine. The operator communicates with the machine via cable or wirelessly, eg via Bluetooth or radio control. The operator controls the machine by means of a remote ...
