On-board wet spraying manipulator system and use method thereof

Abstract

The invention discloses an on-board wet spraying manipulator system, which comprises a transportation vehicle. A rack is arranged on a bottom plate of the transportation vehicle, and a cantilever mechanism, a stirring mechanism, a conveying mechanism and a spraying mechanism are arranged on the rack; the cantilever mechanism includes an installation disc, the installation disc is connected upwardswith a first installation seat, the top of the first installation seat is hinged to a large arm through a connecting pin shaft, large arm driving oil cylinders are arranged on the left side and the right side of the first installation seat correspondingly, cylinder bodies of the large arm driving oil cylinders are both connected with the first installation seat, and extending rods of the large arm driving oil cylinders are both connected with the large arm; and the large arm is connected with a forearm, the upper part of the large arm is fixedly connected with an installation plate downwards,forearm driving oil cylinders are arranged on the left side and the right side of the installation plate correspondingly, and the spraying mechanism is installed at the upper end of the forearm. Theinvention further discloses a corresponding use method. According to the on-board wet spraying manipulator system, the strength requirements on the oil cylinders are lowered, the center of gravity ofa rotary table is lowered, supporting and transmission are more stable and reliable, and the cost of using oil cylinders with the higher specifications is saved; and flow control is accurate, and frequent adjustment is also avoided.

Description

technical field [0001] The invention relates to the technical field of concrete construction, in particular to the concrete spraying technology. Background technique [0002] Concrete spraying machine is a kind of construction equipment widely used in engineering construction. Concrete spraying machine is also called wet spraying manipulator, wet spraying machine, spraying manipulator or spraying robot. Its function is to use compressed air to mix water into a certain proportion of concrete, and transport it to the nozzle of the wet spraying manipulator through pipelines. , after adding the quick-setting agent, it is sprayed at high speed to the sprayed part to quickly solidify and harden to form a concrete support layer. [0003] In order to improve the maneuverability of the wet spray manipulator, a vehicle-mounted wet spray manipulator system has appeared, including a transport vehicle. Including the big arm and the small arm, the stirring mechanism includes a stirring ...

AI Technical Summary

Problems solved by technology

[0004] There is only one boom drive cylinder and forearm drive cylinder in the existing boom drive cylinder, and the boom drive cylinder and the forearm drive cylinder are under a lot of force during work, so it is necessary to use a boom drive cylinder and a forearm drive cylinder with high strength. higher cost

In addition, the degree of freedom of the vehicle-mounted wet spraying manipulator system in the prior art is not enough, and it is impossible to realize 360-degree rotating spraying.
