Abstract
The utility model relates to a control structure for controlling the constant revolution of closed type bidirectional hydraulic pump and motor driven concrete mixing truck tank body. The control structure is characterized in that a hydraulic system consists of a hydraulic variable pump, a motor, a slippage pump, a proportional pressure reducing valve, a comparator and a tank body n revolution sensor, wherein the hydraulic variable pump is connected with the slippage pump, the motor, the tank body n revolution sensor, the comparator and the proportional pressure reducing valve in sequence to form a closed-loop control structure; and the (6)n0 revolution setting of the tank body n revolution sensor is adopted. The control structure realizes the constant revolution of the concrete mixing truck tank body and satisfies the requirement of small power loss. The control mode is simple: the tank body revolution is detected, and the displacement of the hydraulic pump is controlled by the proportional pressure reducing valve; nearly no power is lost on the basis of ensuring the normal running of the concrete mixing truck.
Description
Technical field
The utility model can be realized the control that concrete mixing and transporting car tank body constant speed is rotated, particularly a kind of to closed-type double action crank press to hydraulic pump---the control structure that concrete mixing and transporting car tank body constant speed that motor drives is rotated.
Background technology
The function of concrete mixing and transporting car makes on the one hand transports commerical ready-mixed concrete, is that concrete is further stirred on the other hand, even and car body when not moving in order to prevent that concrete setting from also needing to stir.This stirring needs tank body to rotate under a suitable rotating speed, and this is extremely important to concrete quality.Rotating the closed-type double action crank presses that adopt to hydraulic pump owing to drive the concrete mixing and transporting car tank body more---motor drives, flow is bigger, traditional method is to utilize the method that detects flow to control the method for the discharge capacity of hydraulic pressure pump delivery or motor, exists power attenuation bigger, and control is stable inadequately.
Summary of the invention
The utility model has overcome the defective of above-mentioned existence, purpose is in order to realize the rotation of concrete mixing and transporting car tank body constant speed, and can reach the little requirement of power attenuation again, and control mode is simple, detect by tank body speed, the control mode of proportional pressure-reducing valve control hydraulic pump discharge reaches concrete mixing and transporting car tank body constant speed rotating effect, the control structure that provides a kind of concrete mixing and transporting car tank body constant speed to rotate.
The control structure content Description that the utility model concrete mixing and transporting car tank body constant speed is rotated:
The control structure that the utility model concrete mixing and transporting car tank body constant speed is rotated, it is characterized in that: hydraulic system is made of: hydraulic variable displacement pump, motor, slippage pump, proportional pressure-reducing valve, comparator and tank body n speed probe, hydraulic variable displacement pump is connected with slippage pump, motor, tank body n speed probe, comparator and proportional pressure-reducing valve successively, constitutes closed loop controlling structure.
Adopt tank body n speed probe 6n0 speed setting.
The control structure that the utility model concrete mixing and transporting car tank body constant speed is rotated, realized the rotation of concrete mixing and transporting car tank body constant speed, and can reach the little requirement of power attenuation again, and control mode is simple, detect by tank body speed, the control mode of proportional pressure-reducing valve control hydraulic pump discharge reaches concrete mixing and transporting car tank body constant speed rotates, and on the basis of satisfying the concrete mixing and transporting car operate as normal, does not almost have power attenuation.
Description of drawings
Fig. 1 is the control structure schematic diagram that concrete mixing and transporting car tank body constant speed is rotated
Among the figure: the 1st, hydraulic variable displacement pump, the 2nd, motor, the 3rd, slippage pump, the 4th, proportional pressure-reducing valve, the 5th, comparator, the 6th, tank body n speed probe.
The specific embodiment
The control structure that the utility model concrete mixing and transporting car tank body constant speed is rotated is achieved in that below in conjunction with accompanying drawing and specifies.See Fig. 1, the control structure that the utility model concrete mixing and transporting car tank body constant speed is rotated, hydraulic system is made of: hydraulic variable displacement pump 1, motor 2, slippage pump 3, proportional pressure-reducing valve 4, comparator 5 and tank body n speed probe 6, hydraulic variable displacement pump 1 is connected with slippage pump 3, motor 2, tank body n speed probe 6, comparator 5 and proportional pressure-reducing valve 4 successively, constitutes closed loop controlling structure.Hydraulic variable displacement pump 1 connects and composes closed-loop control with proportional pressure-reducing valve 4 and comparator 5, adopt tank body n speed probe 6n0 speed setting, detect the tank body rotating speed by photoelectric reflection, this signal and setting signal are relatively, produce deviation signal control ratio pressure-reducing valve 4, discharge capacity by proportional pressure-reducing valve 4 control hydraulic control variable pumps 1, constitute closed-loop control, reach concrete mixing and transporting car tank body constant speed and rotate, particularly to closed-type double action crank press to hydraulic pump---the concrete mixing and transporting car tank body constant speed that motor drives is rotated control.
The utility model adopts tank body rotating speed---proportional pressure-reducing valve---hydraulic control variable pump delivery, constitutes closed-loop control concrete mixing and transporting car tank body constant speed and rotates; Proportional pressure-reducing valve 4 inlet pressures are provided by slippage pump 3.
