A power take-off control system, control method, and concrete spraying vehicle

Abstract

The invention discloses a power take-off control system which is used for controlling power transfer between a power device and a hydraulic pump. The system comprises a clutch connected to the power device, a power take-off device arranged between the power device and the hydraulic pump, and a power take-off actuator arranged at the front end of the power take-off device and provided with a pneumatic valve; the system further comprises a power take-off function switch which is connected to the input end of a controller and used for outputting a power take-off signal, a power take-off pressure sensor, a clutch detection sensor and the controller; and the controller is used for receiving signals coming from the power take-off function switch, the power take-off pressure sensor and the clutch detection sensor. The invention further provides a power take-off control method and a concrete guniting trolley. The power take-off control system, the control method and the concrete guniting trolley are low in complexity and favorable for operators to control; and the system reliability is high, and equipment damage can be effectively prevented.

Description

technical field [0001] The present invention relates to the field of construction machinery, and more specifically relates to a force take-off control system, a control method and a concrete shotcrete vehicle. Background technique [0002] With the development of China's science and technology, China's construction machinery has entered a new field, especially the development of concrete machinery has been greatly improved. Concrete machinery is a kind of mechanical equipment that uses machines instead of labor to mix cement, river sand, gravel, water, etc. in a certain proportion to produce concrete required for construction engineering production operations. With the development of China's machinery technology, the application of concrete machinery is becoming more and more extensive, which greatly guarantees the construction of roads, railways, real estate, power infrastructure and rail transit infrastructure in various regions of China, and greatly promotes the developme...

Problems solved by technology

In order to smoothly realize the control of power transmission by the power take-off, the power take-off control system is generally connected to the power take-off. Due to the technical limitations of the existing design, the conventional power take-off control system is very complicated and requires the professional skills of the operator Very high, which is not conducive to the control of the operator; in addition, the reliability of the conventional power take-off control system is relatively low, and the probability of human misoperation is very high, which is easy to cause damage to the equipment
