Problems solved by technology
[0003] The traditional method is to use iron chains to hook the door to prevent its accidental closing. The disadvantage is that it can only limit the movement in one direction, and it still cannot eliminate the accidental impact of the door.
In addition, welding the iron on the deck surface can also achieve the effect of preventing the door from shaking, but it will destroy the smoothness of the deck surface and bring safety hazards

The invention provides a two-way stop device for a ship cabin door, comprising a ratchet mechanism, a locking mechanism, an unlocking angle iron and a connecting rod group. The ratchet mechanism and the locking mechanism are integrally installed on the steel door, so that the The unlocking angle iron is installed on the bulkhead, the connecting rod group includes two hinged connecting rods, the two ends of the connecting rod are respectively connected to the ratchet mechanism and the bulkhead, and the connecting rod group is hinged to the ratchet wheel and Hinged with the bulkhead, the ratchet mechanism includes a ratchet main body and a pawl, the axis of the ratchet main body is rigidly connected to a rotating shaft, the rotating shaft is rigidly connected to the connecting rod group, and the pawl is fitted on the On one side of the ratchet body, the pawl is connected to a first return spring. Through the cooperation of the connecting rod group and the ratchet mechanism, the present invention locks the door at a designated position when the door is opened to a certain angle, so as to prevent the steel door from hitting the equipment behind the door and cause damage, and at the same time avoid unnecessary accidental closure of the steel door. ACCIDENT.
Description
technical field [0001] The invention relates to the technical field of ship construction, in particular to a two-way stop device and a two-way stop method for a ship hatch. Background technique [0002] In the process of sailing or manufacturing of ships, it is often necessary to open and close steel doors. Generally, the weight of the steel door is very large. During the operation of the steel door, the steel door is often damaged due to the collision between the steel door and the equipment behind the door due to improper control. In addition, the swaying cabin can easily cause the door to sway and cause an accidental collision accident, resulting in adverse consequences. Therefore, it is necessary to have a certain angle of the two-way stop on the door. [0003] The traditional method is to use iron chains to hook the hatch door to prevent its accidental closing. In addition, welding the iron on the deck surface can also achieve the function of blocking the shaking of ...
