Mechanical tilt cylinder for concrete mechanical pumping

Abstract

The invention provides a mechanical tilt cylinder for concrete mechanical pumping. The mechanical tilt cylinder comprises fixed mounting seats, wherein fixing bolts are arranged at the outer side of each fixed mounting seat, and a bearing is arranged at the inner side of a connecting rotating hole of each fixed mounting seat; a tilt cylinder hydraulic oil cylinder barrel is rotationally connectedto the inner side of each fixed mounting seat, and a connecting ball head is connected into the bottom of each tilt cylinder hydraulic oil cylinder barrel; a first oil inlet and a second oil inlet arearranged in the top of the outer wall of each tilt cylinder hydraulic oil cylinder barrel; and a hydraulic ejector rod is slidably connected to the interior of each tilt cylinder hydraulic oil cylinder barrel, each hydraulic ejector rod is connected to a connecting pin connected to a tilt cylinder base, and an anti-skid nut is connected to the rear end of each connecting pin. According to the mechanical tilt cylinder, the fixing bolts are screwed into threaded holes of the fixed mounting seats, the two fixing mounting seats are combined and connected, and then the rear ends of the fixing bolts are locked through locking nuts, so that the fixed mounting seats are fixed conveniently, firmness and reliability of the fixed mounting seats are guaranteed, and meanwhile, convenience in replacement of the tilt cylinder hydraulic oil cylinder barrel is improved.

Description

Technical field [0001] The present invention belongs to the technical field of mechanical beam, and more particularly to a concrete mechanical pumping mechanical ring tank. Background technique [0002] Concrete pump, composed of pump body and transport tube, is a mechanical use of pressure, continuous conveying of concrete along the pipe, mainly used in housing construction, bridge and tunnel construction, and is one of the important components of concrete pumps. When the cylinder and the main cylinder are alternately realize the pumping function of the concrete pump, when the beam movement is moved to the end, the primary cylinder operates, in turn, when the primary cylinder is moved to the head, the bench is operated. [0003] Concrete Machinery Pumping Mechanical Well Cylinders can be made to CN1034705555, which mainly includes a swing arm for driving the dispensing valve, two hydraulic cylinders for driving the swing arm left and right, and one end of the two hydraulic cylin...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a concrete mechanical pumping mechanical swing cylinder to solve the problem that when the existing similar concrete mechanical pumping mechanical swing cylinder is in use, the two ends of the swing cylinder are ball heads, and the two ends of the swing cylinder Increased friction will be generated between the base and the base, thereby increasing the wear of the ball heads at both ends of the swing cylinder, and the ball heads at both ends of the swing cylinder will rotate in various directions during use, resulting in unstable swing of the swing cylinder, and The design of the ball joints at both ends of the swing cylinder is inconvenient to replace the swing cylinder
