An internal lubrication system for electric-controlled concrete pistons of concrete pumps

Abstract

The invention relates to an internal lubrication system for an electric-controlled concrete piston of a concrete pump. The system includes a main oil cylinder, a power supply device, a control module, a valve block, a micro-power consumption electric control valve, a concrete cylinder and a concrete piston. In application: the main One end of the oil channel in the piston rod of the oil cylinder is connected with the rodless chamber, the other end is connected with the oil inlet of the valve block, and the oil outlet of the valve block is connected with the oil channel in the concrete piston. The power supply device has two types of electromagnetic induction power supply and battery power supply. kind of form. The invention uses the hydraulic oil in the rodless cavity of the main oil cylinder to lubricate the concrete piston. The structure of the lubrication system is simple, and the operation of the lubrication system is stable and reliable. Piston wear caused by insufficient lubrication of the concrete piston, thereby reducing economic losses caused by the wear of the concrete piston.

Description

technical field [0001] The invention relates to an electric-controlled concrete piston internal lubrication system for concrete pumps, in particular to a novel concrete piston internal lubrication system. technical background [0002] The concrete boom pump truck is an important production tool in the construction industry. As a modern construction method, the concrete boom pump truck has the characteristics of large delivery capacity and fast delivery speed, and has an irreplaceable role in speeding up the construction progress and reducing the construction cost. [0003] The lubrication of the concrete piston of the concrete pump is usually achieved by opening a lubrication hole on the cylinder wall of the delivery cylinder, and then injecting grease into the lubrication hole. When the grease pump pumps grease, if the concrete piston is just at the position of the lubrication hole, If the lubrication is in place, the wear of the concrete piston will be greatly reduced.

[0003] The lubrication of the concrete piston of the concrete pump is usually achieved by opening a lubrication hole on the cylinder wall of the delivery cylinder, and then injecting grease into the lubrication hole. When the grease pump pumps grease, if the concrete piston is just at the position of the lubrication hole, If the lubrication is in place, the wear of the concrete piston will be greatly reduced. However, in actual working conditions, it is difficult for the concrete piston head to move to the position of the lubrication hole when the grease pump pumps grease, and the concrete piston cannot be fully lubricated. As a result, a lot of wear and tear will be caused, which will bring great economic losses. If the concrete pump concrete piston internal lubrication system is used, the problem that the lubrication cannot be in place can be completely solved.
