Cylinder block, actuating cylinder and concrete pumping device

Abstract

The invention discloses a cylinder block of an actuating cylinder, which comprises a cylinder block body (1) and a position detecting member (2) arranged on the cylinder block body (1), wherein the installing position of the position detecting member (2) on the cylinder block body (1) is adjustable along the axial direction of the cylinder block body (1). The invention also discloses an actuating cylinder with the cylinder block, and a concrete pumping device with the actuating cylinder. According to the technical scheme, in an installing and debugging phase of the pumping mechanism, the actual installing position of the position detecting member can be regulated according to the actual configuration of the pumping mechanism so as to adapt to the configuration of the pumping mechanism without replacing the whole pump cylinder, and thus the part adaptability of the pumping cylinder to the pumping mechanism is improved; and in an operation process of the pumping mechanism, the actual installing position of the position detecting member can be regulated in real time according to the operating working condition of the pumping mechanism, and thus the working condition adaptability of the pumping cylinder to the pumping mechanism is improved.

Description

technical field [0001] The invention relates to a cylinder body of an actuator cylinder, and also relates to an actuator cylinder with the cylinder body and a concrete pumping equipment with the actuator cylinder. Background technique [0002] Pumping mechanism (such as concrete pumping equipment) is a kind of equipment widely used in construction machinery, which can be used to pump viscous construction materials such as concrete and mud. Taking concrete pumping equipment as an example, it usually includes two pumping cylinders, two concrete cylinders, two swing cylinders, distribution valves (such as S valves), first reversing valves, second reversing valves, main pumps and Swing pump. The two pumping cylinders can be connected in series, and the main pump drives the two pumping cylinders and controls the movement direction of the pumping cylinders through the first reversing valve. The two pumping cylinders drive the two concrete cylinders respectively. The two swing c...

Problems solved by technology

As a result, the pumping cylinder has poor adaptability to the pumping mechanism, and there are many sizes and varieties of the pumping cylinder, which is not conducive to production organization and management

[0008] (2) After the pumping mechanism has been running for a period of time, the internal leakage of the two pumping cylinders is different, which leads to the difference in the position of the pistons of the two pumping cylinders, which makes the strokes of the two pumping cylinders different. Poor adaptability to time-varying conditions

[0009] (3) During operation, the pumping speed and load of the two pumping cylinders of the pumping mechanism may be different, but the installation positions of the proximity switches on the two pumping cylinders are fixed, so that the pumping mechanism has a Poor adaptability, resulting in the piston of the pumping cylinder not being in place or hitting the cylinder, reducing the pumping efficiency or shortening the service life of the pumping mechanism
