specific Embodiment 1

[0061] The clamp installation aid of the present invention, such as figure 1 As shown, it includes the clamp installation auxiliary bracket and the hydraulic jack 5 placed inside the clamp installation auxiliary bracket. The hoop installation auxiliary bracket includes an upper pressing part 3 and a lower pressing part 4 arranged at intervals up and down, and the two are connected by a connecting piece, which is a double-ended connecting stud 7 . Both the upper pressing piece 3 and the lower pressing piece 4 are of plate structure, and the upper pressing piece 3 and the lower pressing piece 4 are provided with through holes, and the two ends of the double-ended connecting stud 7 pass through the upper pressing piece 3 and the lower pressing piece 4 respectively. The through hole of the connecting nut 8 is threadedly installed on the external thread section at the upper and lower ends of the double-ended connecting stud 7 and is located on the outside of the upper pressing piec...

specific Embodiment 2

[0069] The difference from Example 1 is that the hydraulic jack is installed upside down and fixed on the upper pressure piece, the top of the hydraulic jack is provided with a flange, and the upper pressure piece is provided with a connection hole, and the bolt passes through the flange and the connection hole, and the hydraulic jack is fixedly installed On the upper pressing piece, the connecting holes constitute the mounting structure.

specific Embodiment 3

[0071] The difference from Embodiment 1 is that the horizontal positioning structure is a ring protrusion provided on the pressing member, and the inner structure of the ring protrusion is adapted to the bottom of the hydraulic jack.

Abstract

The invention relates to a hoop installation auxiliary support and a hoop installation auxiliary device. The hoop installation auxiliary support comprises an upper pressing piece, a lower pressing piece and a connecting piece, wherein the upper pressing piece and the lower pressing piece are vertically and oppositely arranged at intervals, and an interval between the upper pressing piece and the lower pressing piece allows a fixed pipeline to penetrate therethrough and is used for containing two to-be-screwed half hoops vertically and oppositely installed on the outer side of the pipeline; theconnecting piece penetrates the upper pressing piece and the lower pressing piece and can allow the upper pressing piece and the lower pressing piece to move in a vertical direction, and a limiting structure for limiting the maximum spacing distance between the upper pressing piece and the lower pressing piece is arranged on the connecting piece; and the upper pressing piece is provided with an installation structure used for installing and fixing a hydraulic jack, or the lower pressing piece is provided with a supporting table used for containing the hydraulic jack. According to the hoop installation auxiliary support, a hoop can be pressed through external force, the two half hoops are close to each other, distances between lug parts on the two sides are the same, the hoop can be screwed down only by one operator, and the problems that an existing hoop is high in installation labor cost and strenuous in screwing, and an instrument on the pipeline is prone to damage are solved.

Description

technical field [0001] The invention relates to a hoop installation auxiliary bracket and a hoop installation auxiliary device. Background technique [0002] As a connection method with simple structure, small size and reliable connection, clamp connection is widely used in oil and gas well pipelines and wellhead connections in my country. Clamp connection gradually replaces flange connection and welding as the main connection method of pipelines. The hoop is mainly composed of two semicircular hoops, and the ears on both sides of the semicircular hoop have connecting holes for connecting and fixing the two semicircular hoops after the studs pass through. [0003] In the prior art, when the clips are installed, the operator needs to forcefully press the ears of the two semicircular clips to make them close to each other, and then use the studs to pass through the connecting holes of the ears, screw on the nuts to tighten the nuts Tighten the nuts after pre-installation. Du...
