Clamping fixture for aligning port of elbow and ports of pipe segments

Abstract

The invention provides a clamping fixture for aligning a port of an elbow and ports of pipe segments. The clamping fixture is characterized by comprising an elbow station and a pipe segment station, wherein the elbow station comprises a leaning bracket and a first horizontal bracket; the leaning bracket is of an inverted 'U'-shaped structure, the first horizontal bracket comprises two parallel beams, the two parallel beams are fixed to the side faces of two vertical beams of the leaning bracket correspondingly, and the lower sides of the two parallel beams of the first horizontal bracket are each provided with a rack; the two vertical beams of the leaning bracket are sleeved with a sliding sleeve, the side face of the side, close to the first horizontal bracket, of the sliding sleeve is fixedly provided with a vertical second sleeve, the second sleeve is internally provided with a jacking rod in a penetrated manner, the side face of the second sleeve is provided with a hole, a bolt is screwed into the hole, the bolt props against the jacking rod, and the top of the jacking rod is provided with a supporting seat; and a horizontal calibration ruler is hinged to the supporting seat, the horizontal calibration ruler is just parallel to the two parallel beams of the first horizontal bracket when being rotated to the lowest position, the middle of the sliding sleeve is provided with a second lead screw in a penetrated manner, and the second lead screw is parallel to the two parallel beams of the first horizontal bracket.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a mold for matching elbow pipe sections. Background technique [0002] During the prefabrication process of existing pipelines, pipe sections and pipe fittings need to be matched. Due to the welding and sealing requirements, the requirements for matching are relatively high. The traditional method of matching elbows and pipe sections is generally based on channel steel or angle steel, and then The elbow and the pipe section are assembled on the top, or directly on the ground, and the welding rod steel core or flat iron is clamped between the pipe section and the elbow interface to keep the gap between the joints. Multiple people need to use crowbars and sledgehammers , Flat iron and other tools are assembled. This method has the following defects: After spot welding, the inappropriate gaps and wrong edges are trimmed with an angle grinder. If the angle does not match, the cuts must...

[0002] During the prefabrication process of existing pipelines, pipe sections and pipe fittings need to be matched. Due to the welding and sealing requirements, the requirements for matching are relatively high. The traditional method of matching elbows and pipe sections is generally based on channel steel or angle steel, and then The elbow and the pipe section are assembled on the top, or directly on the ground, and the welding rod steel core or flat iron is clamped between the pipe section and the elbow interface to keep the gap between the joints. Multiple people need to use crowbars and sledgehammers , Flat iron and other tools are assembled. This method has the following defects: After spot welding, the inappropriate gaps and wrong edges are trimmed with an angle grinder. If the angle does not match, the cuts must be reassembled. The error boundary value exceeds the standard, the gap between the joints does not meet the welding requirements, and the joints are folded, etc. The quality of the joints is random and the construction is difficult; the construction personnel are required to have high skills, and employees without rich construction experience cannot complete the counterpart work; many people are required Cooperating to complete the matching work is labor-intensive and time-consuming; due to the difficulty of butt jointing, and the pipe elbows are quite bulky, the traditional butt joint method can easily cause workers to be injured; with the increase of pipe diameter, it is difficult to complete the wrong joint, joint gap and angle. Adjustment, the counterpart is more difficult
