Abstract

The invention discloses a concrete pump and a concrete piston lubricating system of the concrete pump. The concrete piston lubricating system comprises a position detection device, a control device and a lubricant distribution device. The position detection device is used for detecting the position of a concrete piston. The control device is connected with the position detection device and the lubricant distribution device. The lubricant distribution device is connected with a lubricating hole corresponding to the concrete piston. In the process of lubrication, the control device controls a main oil cylinder to move to retract the concrete piston. After the position detection device detects that the concrete piston returns in place, the control device controls the lubricant distribution device to make lubricant flow to the lubricating hole, so that an oil groove of the concrete piston is filled with the lubricant. By the adoption of a concentrated lubrication mode, a large amount of lubricant can be injected into the concrete piston and the concrete piston lubricating system has the advantages of being good in lubricating effect, low in lubricating cost, small in environmental pollution and the like.

Description

technical field [0001] The invention mainly relates to the technical field of concrete engineering machinery, in particular to a concrete pump concrete piston lubricating system and a concrete pump provided with the concrete piston lubricating system. Background technique [0002] The concrete piston is the key component of the concrete pump, and it is also a vulnerable part. Driven by the main oil cylinder, the concrete piston reciprocates in the delivery cylinder. During this movement, friction is inevitably formed between the concrete piston and the inner wall of the delivery cylinder. Therefore, lubricating between the concrete piston and the delivery cylinder to reduce the wear of the concrete piston is a prerequisite for ensuring the smooth operation of the concrete pump. [0003] In the prior art, the concrete piston lubrication methods mainly include manual lubrication and synchronous automatic lubrication. Manual lubrication is used to add lubricant to the concre...
