Detailed Description
The invention is described in further detail below with reference to the accompanying drawings:
referring to fig. 1, an embodiment of a concrete pumping and stirring system according to the present invention includes a pumping and stirring system used during pumping work, where the pumping and stirring system includes a hydraulic oil tank 6, a first hydraulic pump 7, a stirring valve 12, a stirring motor 13, and a stirring mechanism 14. The output end of the first hydraulic pump 7 is connected to the input end of the stirring valve 12, the stirring valve 12 is communicated with the stirring motor 13, the stirring motor 13 is connected with the stirring mechanism 14, and the output oil path of the stirring motor 13 is communicated with the hydraulic oil tank 6. The electric stirring device is characterized by further comprising an electric stirring driving mechanism consisting of a switch relay 1, a power battery 2, an inverter 3, a motor 4 and a second hydraulic pump 5, wherein the power battery 2 is connected with the motor 4 through the inverter 3, and a switch relay 1 is arranged on a connecting lead between the power battery 2 and the inverter. The electric motor 4 is connected to a second hydraulic pump 5, the output of which second hydraulic pump 5 is connected to the input of the mixing valve 12.
Further, in order to charge the power battery 2, the electric agitation drive mechanism further includes a hydraulic motor 8 and a generator 9, the hydraulic motor 8 is communicated with an oil outlet pipe of the hydraulic pump 7, the hydraulic motor 8 is connected to the generator 9, and the generator 9 is connected to the inverter 3.
Furthermore, in order to prevent the pressure oil path during the pumping operation from influencing the pressure oil path during the material-waiting stage, a second check valve 10 is arranged between the output end of the second hydraulic pump 5 and the stirring valve 12; a first check valve 11 is arranged between the first hydraulic pump 7 and the mixing valve 12.
Preferably, the inverter 3 is a charging and inverting integrated machine, and has an inverting function and a charging management function.
Still further, the power battery 2 has an external plug-in charging interface, and can be charged by a power supply on a parking lot or a construction site.
Referring to fig. 1, an embodiment of the pumping device of the present invention includes a stirring system, and the stirring system is the above-mentioned concrete pumping stirring system.
Further, the pumping equipment comprises a concrete pump truck, a vehicle-mounted pump and a wet spraying machine.
During the use, before concrete pump truck (or vehicle pump, wet blasting machine) began to go to the building site, earlier through external electricity of inserting charge interface with power battery 2 full charge, switch relay 1 is in the off-state. After the concrete is delivered to a construction site, when the pumping equipment pumps the concrete, the stirring mechanism 14 is powered by the chassis engine, the first hydraulic pump 7 mounted on the transfer case is driven to provide pressure oil through the transfer case, and the stirring motor 13 is driven to rotate, so that the stirring mechanism 14 is driven to work. Due to the presence of the first check valve 10, the pressure oil does not enter the second hydraulic pump 5.
When the pump is stopped and materials are to be mixed, the chassis is flamed out, the switch relay 1 is switched on, the power battery 2 supplies power to the motor 4 through the inverter 3, the motor 4 starts to work, the second hydraulic pump 5 is driven to pump out pressure oil, the stirring motor 13 is driven to rotate through the stirring valve 12, and therefore the stirring mechanism 14 is driven to work. Due to the existence of the second check valve 11, the pressure oil cannot enter the first hydraulic pump 7, and the pressure oil path during pumping work and the pressure oil path during the material waiting stage cannot influence each other. It can be seen that even when the pump is stopped, the second hydraulic pump 5 supplies the pressure oil to drive the stirring motor 13, but the second hydraulic pump 5 is driven by the electric motor 4, so that the problem of insufficient torque does not occur.
When the concrete pump truck (or vehicle-mounted pump, wet blasting machine) pumps concrete, the first hydraulic pump 7 also provides pressure oil for the hydraulic motor 8 at the same time, the hydraulic motor 8 drives the generator 9 to work, the electric energy generated by the generator 9 charges the power battery 2 through the inverter 3 with the charging management function, and the electric energy consumption caused by the working of the electric motor 4 under the material extinguishing and other states can be partially compensated.
In addition, because the power battery 2 has the function of plug-in charging, most of the sites have power supplies, and the power battery 2 can be charged, so that the power battery 2 is ensured to have sufficient electric energy.
It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art may make modifications, alterations, additions or substitutions within the spirit and scope of the present invention.
