Embodiment Construction

[0008] figure 1 It is a structural representation of a specific embodiment of the present invention, combined below figure 1 The embodiments of the present invention are introduced.

[0009] Such as figure 1 As shown, the manual water ceiling height device provided by the present invention includes a cross bar (1), which is connected to a rotating body (2), and a pin plate (3) is fixed on the rotating body (2), and the pin A fixed plate (4) is arranged on the plane on which the plate (3) rotates, and a shear pin hole (5) and a limit pin hole (6) are arranged on the fixed plate (4).

[0010] In the manual water upper limit device provided by the present invention, when the cross bar is in the closed state and the position of the pin plate is facing the shear pin hole, the shear pin is inserted at this time to fix the position of the cross bar, and the shear pin will automatically cut off when the cross bar encounters a strong impact Make the crossbar open to protect the safe...

Abstract

The invention provides a manual water height limiting device, which comprises a cross rod (1). The cross rod (1) is connected with a rotating body (2); a pin plate (3) is fixed on the rotating body (2); and a fixing plate (4) is arranged on the rotating plane of the pin plate (3) and is provided with a shear pin hole (5) and a limit pin hole (6). By the manual water height limiting device, when the cross rod is in a closing state, the pin plate is opposite to the shear pin hole, and a shear pin is inserted into the shear pin hole to fix the cross rod at the moment, and can be automatically sheared to open the cross rod when the cross rod meets strong impact, so that the safety of ships and personnel is ensured; and when the cross rod is in an opening state, the pin plate is opposite to the limit pin hole, and a pin is inserted into the limit pin hole to fix the opened cross rod at the moment, so that the cross rod is not required to be fixed manually, and work efficiency is greatly improved.

Description

technical field [0001] The invention relates to a height limiting device, in particular to a manual water height limiting device. Background technique [0002] At present, the manual water upper limit device generally includes a cross bar, a rotating body and a support seat, and by manually rotating the rotating body, the cross bar is driven to rotate to realize the opening and closing of the cross bar. [0003] The existing technology can easily realize the opening and closing of the cross bar, but there is no mechanism for fixing the cross bar, so when the cross bar needs to be in the open state for a long time, it is necessary to manually fix the rotating body in the open position for a long time, which is a waste of labor. , work efficiency is low. Contents of the invention [0004] In view of the above-mentioned defects, the manual water upper limit device provided by the present invention adopts the limit pin hole and the shear pin hole to fix the opening and closin...
