A concrete shotcreting car and a jib system thereof

Abstract

The invention discloses a jib system of a concrete shotcreting car, comprising a jib, a sprinkle-nozzle and a lighting device. The jib comprises at least three knuckle arms that are connected in turn, and the sprinkle-nozzle is arranged on the last knuckle arm. The jib system of the concrete shotcreting car is characterized in that the lighting device is arranged on a knuckle arm except the last knuckle arm; the jib system also comprises a controller and a driving device used for driving the lighting device to rotate; the controller is responsible for measuring the rotation angle of the sprinkle-nozzle relative to the lighting device, and outputting the corresponding angle that is used for controlling the driving device to drive the lighting device to rotate in accordance with the rotation angle. In the jib system, the lighting device is arranged at the position that is far away from the sprinkle-nozzle on the last knuckle arm, so that the lighting device is not easy to be covered by substances such as motar, etc., and be destroyed; the jib system also comprises the controller and the driving device, the driving device can be controlled to drive the lighting device to rotate in accordance with the variation of the sprinkle-nozzle position, so that the lighting device is always toward the sprinkle-nozzle, and accordingly, the actual construction position always has better lighting environment.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a boom system of a concrete spraying vehicle. The invention also relates to a concrete shotcrete vehicle comprising the above-mentioned boom system. Background technique [0002] Concrete machinery is widely used in hydropower tunnels, underground powerhouses, subway engineering, railway tunnels, geotechnical engineering, military underground engineering and other fields, involving various working environments such as fields and tunnels. [0003] Take the concrete shotcrete vehicle as an example. The concrete shotcrete vehicle has a boom system. In order to meet the rapid operation under various environmental conditions, the boom system needs to be able to expand and contract in multiple directions and in multiple planes. Therefore, the boom The frame system is a structure composed of a foldable, unfolded and telescopic planar four-bar linkage mechanism hinged by m...

AI Technical Summary

Problems solved by technology

Then the lighting can follow the jib's variable amplitude and telescopic movement, and maintain the consistency with the position of the nozzle, which makes up for the defect of the fixed rear end to a certain extent, but it is very close to the construction site, so the lighting is easy to damage Or it is easy to be covered by mortar, etc., which affects the lighting effect and has a short service life, which is likely to cause safety hazards

In addition, the front end is fixed, and the lighting system cannot provide lighting for the rear end of the shotcrete vehicle. In order to improve the overall lighting effect, it is necessary to set up another lighting lamp for the rear end, which increases the production cost.
