Abstract

The invention discloses a flexible ironing vibration same frequency hydraulic drive device. The flexible ironing vibration same frequency hydraulic drive device comprises a first vibration motor, a second vibration motor, a third vibration motor, a fourth vibration motor, a first pipeline, a second pipeline, a third pipeline, a fourth pipeline, a fifth pipeline, a sixth pipeline, a seventh pipeline, an eighth pipeline, a main vibration shaft, a left vibration shaft, a right vibration shaft, and an oil tank. One end of the third pipeline is connected with an oil outlet of the first vibration motor, the other end of the third pipeline is connected with an oil inlet of the second vibration motor, one end of the fourth pipeline is connected with an oil outlet of the second vibration motor, the other end of the fourth pipeline is connected with the fifth pipeline, one end of the seventh pipeline is connected with an oil inlet of the third vibration motor, and the other end of the seventh pipeline is connected with an oil outlet of the fourth vibration motor. The flexible ironing vibration same frequency hydraulic drive device has the advantages of being simple in structure, convenient to use, strong in effectiveness, high in road surface prepressing solidity, low in production cost, and convenient to popularize and use.

Description

technical field [0001] The invention relates to a hydraulic driving device, in particular to a telescopic screed and vibrating co-frequency hydraulic driving device. Background technique [0002] Telescopic screed is a wide-range-adjustable screed device. According to the requirements of road construction, the vibration frequency of the main screed section and the left and right telescopic sections of telescopic screed must be the same. Uniform compaction. To ensure the same vibration frequency for telescopic screeds, diverter valves or multi-pump and multi-circuit methods are generally used. Due to structural reasons, diverter valves have low diversion accuracy, low hydraulic efficiency, and high heat generation, and multi-pump and multi-circuit structures are complex and costly. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the above-mentioned prior art, and provide a telescopic screed vibrating co-frequency h...
