An adjustable ship guardrail protection device and its application method

Abstract

The invention discloses an adjustable ship guardrail protection device. The device comprises a left stabilizing column and a right stabilizing column, the left stabilizing column is fixedly provided with stabilizing sleeves, and the right stabilizing column is fixedly provided with adaptive rods. One end of each adaptive rod is inserted into an inner cavity of the corresponding stabilizing sleeve,and stabilizing bearings are embedded in the side, close to the right stabilizing column, of the left stabilizing column. The adaptive rods are perpendicularly connected with a matching plate, nuts are installed in the middle of the matching plate, and the center of the nuts and the center of the stabilizing bearings are located on the same straight line. One end of a threaded rod penetrates through the stabilizing bearings and the nuts in sequence, and clamping mechanisms are arranged on the sides, away from each other, of the left stabilizing column and the right stabilizing column. The distance between the left stabilizing column and the right stabilizing column can be increased by moving the right stabilizing column, so that the total length of a guardrail is increased, the protectiveeffect of the guardrail can be effectively improved, the device is suitable for protecting tunnel portals in different sizes, and the construction safety of constructors is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of ship protection devices, and in particular relates to an adjustable ship guardrail protection device and a use method thereof. Background technique [0002] At present, in the process of large-scale shipbuilding, the middle group and large group of the subsections go to the loading site for general assembly, and the workers work on the subsections. There will be upper tire frames on the straight and curved sections, and the tire frames will be installed again. It is divided into fixed tire frame and snap tire frame, but the lowest tire frame is also 1 meter high, and the ship loaded into the dock in the later stage is tens of meters high. There will be holes of different sizes in the structure, and such holes will bring safety hazards to the workers on site. At this time, a guardrail protection device for ships is needed to protect the surroundings of the holes. Contents of the invention [0003] Aimin...

[0002] At present, in the process of large-scale shipbuilding, the middle group and large group of the subsections go to the loading site for general assembly, and the workers work on the subsections. There will be upper tire frames on the straight and curved sections, and the tire frames will be installed again. It is divided into fixed tire frame and snap tire frame, but the lowest tire frame is also 1 meter high, and the ship loaded into the dock in the later stage is tens of meters high. There will be holes of different sizes in the structure. Such holes will bring safety hazards to the workers on site. At this time, a guardrail protection device for ships is needed to protect the surroundings of the holes.
