Concrete delivery pump lubricating system and concrete pumping equipment

Abstract

The invention relates to the technical field of concrete pumping equipment and particularly discloses a concrete delivery pump lubricating system which is used for a lubricating and stirring system and a pumping system and comprises a lubricating grease box, a lubricating grease pump and an auxiliary lubricating device, wherein the auxiliary lubricating device is used for providing lubricating grease for the stirring system, and the oil outlet of the auxiliary lubricating device is communicated with the lubricating point of the stirring system. When the pumping system stops working, the auxiliary lubricating device can provide the lubricating grease for the lubricating point of the stirring system when the stirring system works to lubricate a kinematic pair in the stirring system, so thateach element in the stirring system can not be abraded easily, and the service life of each element is prolonged. The invention also discloses the concrete pumping equipment with the concrete delivery pump lubricating system.

Description

technical field [0001] The invention relates to the technical field of concrete pumping equipment, in particular to a concrete pump lubrication system. The present invention also relates to a concrete pumping equipment with the above-mentioned lubrication system of the concrete delivery pump. Background technique [0002] Concrete pumping equipment such as concrete pumps, pump trucks, vehicle-mounted pumps, wet spraying machines, etc., in the process of pumping concrete, in order to ensure a certain degree of lubrication between the moving pairs in the equipment, and to prevent the infiltration of cement in the delivery cylinder and wear The moving parts cause slurry leakage, and the concrete delivery pump lubrication system is usually set up to lubricate the lubrication points of the mixing system, pumping system and other working systems of the concrete pumping equipment. [0003] Please see figure 1 , figure 1 It is a schematic diagram of the principle of a typical con...

AI Technical Summary

Problems solved by technology

[0007] In the concrete delivery pump lubrication system of this structure, the hydraulic oil source used to drive the grease pump 3 comes from the power source of the pumping system 6. Once the pumping system 6 stops working, the hydraulic oil source stops providing hydraulic pressure to the grease pump 3. Oil, that is, the lubrication system of the concrete delivery pump stops working, and the grease pump 3 can no longer provide grease to each lubrication point, and cannot lubricate each lubrication point; while the mixing system 5 is still working at this time, the mixing system 5 Each kinematic pair still needs to be lubricated. If the lubrication of each lubrication point in the mixing system 5 is stopped, the corresponding components in the mixing system 5 will be easily worn and the service life will be greatly shortened.
