The oil tank is connected with a seven-linkage electromagnetic reversing valve and a three-linkage gear pump; and the seven-linkage electromagnetic reversing valve comprises a confluence electromagnetic valve,a first linkage electromagnetic valve, a second linkage electric proportional valve, a third linkage electric proportional valve, a fourth linkage electric proportional valve, a fifth linkage electromagnetic valve, a sixth linkage electromagnetic valve and a seventh linkage electromagnetic valve which are integrated into a whole valve block or installed separately. The functions of auger scraping, left-right leveling of a leveling head mechanism, inclination angle adjusting, high-low-speed walking, priority, skid resistance, oscillation and vibration, steering, emergency movement, composite action and the like are achieved through the seven-linkage electromagnetic reversing valve, so that the high integration level is achieved, the convenience in installation and maintenance is realized,the climbing force of the equipment is effectively improved, the vehicle speed is controllable during downhill running, the stability in steering is realized, the performance of the laser leveling machine is remarkably improved, and rapid and high-precision leveling operation of a concrete floor is realized.

Description

technical field [0001] The invention relates to a hydraulic system of a high-performance small four-wheel laser leveler, belonging to the technical field of leveler hydraulic systems. Background technique [0002] The small four-wheel laser leveling machine is developed according to the increasing demand for ground quality such as strength, flatness, and levelness in modern industrial plants, large shopping malls, warehouses, and other large-area cement concrete floors. It is widely used Special equipment for large-area concrete ground leveling operations. The leveling head mechanism of the laser leveling machine takes the laser signal emitted by the transmitter as the positioning reference plane, and receives the laser signal in real time through the laser receiver to control the working state of the leveling head. At the same time, the high-frequency vibrator ensures that the concrete is compacted and the matrix is ​​uniform. , the laser system, computer system, hydraulic...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the hydraulic system of the small and medium-sized four-wheel laser leveling machine drives and controls the mechanical action, and realizes functions such as exercising, turning, and leveling, and has the following defects: (1) The traction force is insufficient during work. When one tire is attached to the ground with insufficient force or suspended in the air, it is easy to cause tire slippage and poor passing ability of the work platform; (2) the lack of high-speed walking of the laser leveling machine leads to slow transition speed, and it is difficult to adapt to the rapid transition of different sites; (3) There are air suction and cavitation phenomena in the oil circuit of the travel motor, which causes abnormal noise of the motor when braking and parking, which affects the service life of the travel motor; (4) Lack of flow control in the oil circuit, resulting in uncontrolled vehicle speed when going downhill; (5) When walking, there is a sense of impact when turning suddenly; (6) The system is scattered, the utilization rate of components is low, and the installation of pipelines is inconvenient, resulting in damage to the sealing rings at the hydraulic hoses and hydraulic joints, and a high risk of hydraulic oil leakage, thus It is difficult to meet the application requirements of the small four-wheel laser leveling machine, which affects the performance of the laser leveling machine
