A Welding and Clamping Device for Elbow Joints in Water Conservancy Construction

Abstract

The invention discloses a hydraulic engineering construction bent pipe joint welding clamping device which clamps a bent pipe to adjust the extension amounts of a plurality of oil cylinders so that bending of the bent pipe and butting of a connecting pipe can be achieved. The hydraulic engineering construction bent pipe joint welding clamping device is characterized in that a plurality of installation holes are formed in a fixing ring at equal angles, and penetrate through the inner and outer rings of the fixing ring, the four installation holes are optimized, and thread sleeves are arranged in the installation holes; screws are arranged in the thread sleeves in a screw-joint mode, one ends of the screws are arranged in the fixing ring, the other ends of the screws are arranged outside thefixing ring, and clamping plates are arranged at one ends of the screws; the multiple clamping plates are combined to form a circular ring, the clamping plates are formed by bending steel plates, onelayer of rubber sleeve is arranged on the surface of each clamping plate, and a plurality of permanent magnets are arranged in each clamping plate in an embedded mode; and a plurality of hinged frames are arranged on the end face of the fixing ring, and located between every two adjacent installation holes correspondingly, one ends of the multiple hydraulic oil cylinders are arranged on the hinged frames in a hinged mode correspondingly, and oil-ways among the multiple hydraulic oil cylinders are independent mutually.

Description

technical field [0001] The invention relates to a welding and clamping device for elbow joints in water conservancy construction, which relates to a device for welding and clamping the two ends of an elbow at a bending position during the laying process of drainage management, and belongs to the field of water conservancy facilities. In particular, it relates to a welding clamping device that adjusts the protruding amount of a plurality of oil cylinders by clamping the bent pipe so that the bent pipe is bent and the connecting pipes are butt-jointed. Background technique [0002] At present, in the construction of water conservancy projects, it is necessary to lay drainage pipes. During the construction process, it is often necessary to bend the pipes due to the terrain to avoid obstacles. When bending, the pipes are bent in advance. Design the angle, and then weld on site. During welding, due to the strange shape of the bent part, there are right-angled bends, "S" shapes, e...

AI Technical Summary

Problems solved by technology

The invention clamps and rotates the elbow through the turntable, and the elbow rotates synchronously during the process. During the laying of the water pipe, it is difficult to rotate due to the length and volume of the pipe, so this device is not suitable for the welding alignment of the water pipe, and the water pipe No flange at the welding position and no clamping fixation via the flange
