Embodiment Construction

[0029] see figure 1 (The direction of the arrow is the sliding direction of the sliding mount), figure 2 , Figure 6 , Figure 7 As shown, the present invention is an intracavity installation frame of an internal deviation correction device. The intracavity installation frame includes a rotating base 1 installed with the bottom plate of the joint cavity and a rotating beam 2 installed on the upper part of the rotating base. On the rotating beam There is a sliding mounting seat 3 that can be used to install the internal deviation correction device. The left end of the rotating beam is hinged to the rotating base, and the right end of the rotating beam is connected to a lifting mechanism; Leg 4. The invention adopts the hinged design of the rotating beam and the rotating base; it can realize the rotating connection between the rotating beam and the rotating base; the internal deviation correcting device can be quickly installed in the joint cavity; when hoisted into the join...

Abstract

The invention relates to an intra-cavity mounting rack of an inside deviation rectifying device, in particular to a mounting rack for mounting the inside deviation rectifying device in a joint cavity between two pipe joints and enabling the mounting of the inside deviation rectifying device to conform to the requirements of deviation rectifying in a pipe. The intra-cavity mounting rack comprises a rotary foundation support and a rotary beam mounted on the rotary foundation support, the rotary beam is provided with a sliding mounting base, one end of the rotary beam is hinged to the rotary foundation support, and the other end of the rotary beam is connected with a hoisting mechanism. According to the intra-cavity mounting rack, the rotary beam is provided with the sliding mounting base; the problem of mounting the inside deviation rectifying device in the joint cavity is solved, the device mounting process is simplified, the operating risk is lowered, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a cavity mounting frame of an internal deviation correcting device, in particular to a mounting frame for installing an internal deviation correcting device in a joint cavity between two pipe joints, so that the installation of the internal deviation correcting device meets the requirements of the internal deviation correcting operation. Background technique [0002] At present, highway subsea tunnels are connected by a plurality of immersed tubes. The volume and weight of the immersed tubes are quite large. Generally, the length is about 100-200 meters. The immersed tubes are installed on the pre-laid foundation bed. The butt ends of each immersed tube are installed with GINA waterstops, which act as a seal. During the sinking and docking process of each immersed tube, both ends are sealed with end seals. Between the end seals and the GINA waterstop forms a junction cavity. After the butt joint of the immersed tube is complet...
