Problems solved by technology
When the main oil pump works in the constant power control area, the former often has insufficient power of the oil cylinder of the distribution valve due to the increase of the pressure of the oil pump and the decrease of the displacement, and the hydraulic shock of the oil circuit is relatively large; the constant pressure pump of the oil circuit of the distribution valve of the latter is Frequent switching of the working state between the maximum displacement and the minimum displacement results in shortened working life, increased failure rate, and failure of the oil pump to give full play to its performance
The above-mentioned defects adversely affect the working reliability of the concrete pump and increase the manufacturing and maintenance costs of the product

Embodiment Construction
[0018] according to figure 1 An embodiment of an auxiliary energy storage and flow increasing device for a concrete pump hydraulic system of the present invention with the above-mentioned structure, there is a connecting oil circuit 1 connected by a hydraulic hose, one end of the connecting oil circuit 1 is the input end P, and the other end is the output end B . The one-way valve 11 adopts a commercially available one-way valve product whose model is S10. The accumulator 10 adopts a commercially available accumulator product whose model is XL4. The relief valve 12 adopts a commercially available relief valve product whose model is DB10.
[0019] From figure 2 ~3 It can be seen that the variable (quantitative) pump 3 provides hydraulic oil to the auxiliary energy storage flow increasing device, and the hydraulic oil enters from the input port P and outputs from the output port B. The pressure oil output from the output terminal B through the check valve (11) communicates...

Present invention discloses a hydraulics energy storage flow increasing device of concrete pump. Said device has connection oil circuit with input end P and output end B, one-way valve connected oil circuit between input end P and output end B, an energy accumulator and spillover valve having output end T connected with oil circuit between one-way valve with input end P. Said Pressure oil Pressure oil enters from input end P, making energy accumulation to accumulator and outputting power oil through one-way valve, output end oil circuit pressure controlling accumulator state, spillover valve configuring overflow pressure, the overflow hydraulic oil flowing back to oil tank through output end T, in working oil circuit device distribution valve oil circuit commutation process or not commutation process , said device releasing relevant power oil to supply requirement. Said technic scheme is security and smoothness operation of oil pump.
Description
technical field [0001] The invention relates to an auxiliary energy storage and flow increasing device for a hydraulic system of a concrete pump. Background technique [0002] The hydraulic system of the concrete pump completes the driving functions of concrete pumping, distribution and mixing devices in the concrete pump. The existing hydraulic system is composed of a working oil circuit device and a stirring oil circuit device, that is, the so-called double-pump oil supply, see Figure 5 ; One is composed of a pumping oil circuit device, a distribution oil circuit device and a stirring oil circuit device, namely the so-called three-pump oil supply, see Figure 4 . They all lack auxiliary accumulator flow increasing device. When the main oil pump works in the constant power control area, the former often has the phenomenon of insufficient power of the oil cylinder of the distribution valve due to the increase of the pressure of the oil pump and the decrease of the displac...
