Embodiment Construction

[0015] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0016] Such as figure 1 and figure 2 As shown, an embodiment of the present invention provides a cylinder body of an actuating cylinder, wherein the cylinder body includes an inner liner 1 and a first fiber composite material layer 2 combined on the outside of the inner liner 1 .

[0017] Through the above technical solution, the cylinder body of the actuating cylinder includes the inner lining layer 1 and the first fiber composite material layer 2. Compared with the existing metal materials, the fiber composite material is lighter in weight under the same strength and has better fatigue resistance. It has good corrosion resistance and low thermal expansion,...

Abstract

The invention discloses a cylinder body of an actuating cylinder, which comprises an inner lining (1) and a first fiber composite material layer (2) bonded outside the inner lining, wherein the first fiber composite material layer is laminated by a first fiber material and a resin matrix. The invention also discloses concrete pumping equipment comprising the cylinder body. Accordingly, the invention further discloses a manufacturing method of the cylinder body of the actuating cylinder, which comprises an inner lining forming step of forming the inner lining, and a bonding step of forming the first fiber composite material layer with the first fiber material and the resin matrix and bonding the first fiber composite material layer to the outer part of the inner lining. According to the technical scheme, the cylinder body of the actuating cylinder has higher strength and lighter weight, is better in fatigue resistance and corrosion resistance, and has low thermal expansibility. Besides, since the inner lining of the cylinder body can meet the requirements for tightness of the cylinder body inner wall and the wear resistance upon contact with a piston, the inner lining does not affect the service performance of the cylinder body.

Description

technical field [0001] The present invention relates to the field of actuator cylinders, in particular to a cylinder body of the actuator cylinder and a manufacturing method of the cylinder body, and also relates to concrete pumping equipment with the cylinder body. Background technique [0002] Actuating cylinders generally include hydraulic and pneumatic cylinders and are used in a wide variety of applications. For example, taking a hydraulic cylinder as an example, concrete pumping equipment (such as a concrete pump truck) usually includes a hydraulic cylinder for driving the reciprocating movement of the concrete cylinder to transport concrete. At present, in the process of concrete action, more and more concrete transportation work is completed by concrete pump truck. With the rapid development of concrete machinery technology, engineering operations require concrete to be transported to higher and farther distances. The materials selected for the boom, hydraulic cylin...
