Description
Technical Field
The invention belongs to the technical field of ship engineering, relates to a novel ear shaft sleeve protection device, and in particular relates to a device for protecting a bridge trunnion seat on a ship body under the condition that a bridge trunnion is not installed.
Background
The cutter suction dredger is an engineering ship which is widely applied in the engineering fields of dredging channels, seagoing field making and the like at present. One end of the ship body is provided with a slot for installing a bridge device provided with a reamer and other equipment. In general, cutter suction dredgers are provided with a rotation point, namely a bridge rotation trunnion, and correspondingly, only one set of bridge trunnion seats is arranged on the ship body as a corresponding supporting structure. However, with the development of cutter suction dredgers, in order to meet different dredging requirements, both minimum dredging and maximum dredging are required, and it is difficult to simultaneously achieve the requirements if the bridge rotating trunnion is fixed at only one installation position. In order to solve the problem, the cutter suction dredger provides mounting positions for the bridge rotating trunnion at two different height positions of the ship body, namely, the different height positions of the ship body are respectively provided with a trunnion seat which is matched with the bridge rotating trunnion in a mounting and fixing way.
When the cutter suction dredger is used for construction, the bridge rotating trunnion can only be arranged at one height position, namely, only one trunnion seat on the dredger is put into use, and the rest is in an idle and standby state.
Because of the relatively large number of equipment on the ship and the relatively complex conditions, in order to prevent the idle trunnion seat from being damaged, the equipment can be rapidly put into the next use in an intact state, and a novel device for protecting the trunnion sleeve is urgently needed to be developed.

the earring seat protection cover is in a cylindrical shape combined in a stepped mode, the outer diameter of a cylinder body of the earring seat protection cover is matched with the inner diameter of a shaft sleeve in the bridge earring seat, the length of the earring seat protection cover is matched with the length of the shaft sleeve in the bridge earring seat, and a plurality of bolt holes are uniformly formed in the edge of the largest cylinder at the bottom of the earring seat protection cover;
the rotary bolt column is fixed in the threaded hole, one end of the rotary bolt column is provided with a rotatable wrench, and the other end of the rotary bolt column is welded with a clamping plate.
Further, the trunnion seat protection cover is formed by sequentially welding a plurality of sections of steel cylinders with gradually decreasing cylinder diameters, and a plurality of bolt holes matched with the rotary bolt columns are uniformly arranged at the edge of the largest cylinder at the bottom of the trunnion seat protection cover.
Further, the wrench is rectangular, one end of the wrench is provided with a round hole, and the wrench is fixed at the end part of the rotary bolt column.
The bridge trunnion seat protection device provided by the invention can prevent the idle trunnion seat from being damaged, and can be rapidly put into next use in an intact state.

Detailed Description
In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced without one or more of these details. In other instances, well-known features have not been described in detail in order to avoid obscuring the invention.
In order to provide a thorough understanding of the present invention, detailed steps and detailed structures will be presented in the following description in order to explain the technical solution of the present invention. Preferred embodiments of the present invention are described in detail below, however, the present invention may have other embodiments in addition to these detailed descriptions.
The invention provides a bridge trunnion seat protection device, which is shown by referring to figures 1-3 and comprises:
the earring seat protection cover 1 is in a cylindrical shape combined in a stepped manner, the outer diameter of a cylinder body of the earring seat protection cover 1 is matched with the inner diameter of a shaft sleeve in the bridge earring seat, the length of the earring seat protection cover is matched with the length of the shaft sleeve in the bridge earring seat, and a plurality of bolt holes are uniformly formed in the edge of the largest cylinder at the bottom of the earring seat protection cover 1;
the rotary bolt column 2 is fixed in the threaded hole, one end of the rotary bolt column is provided with a rotatable wrench 3, and the other end of the rotary bolt column is welded with a clamping plate. The rotary stud 2 is secured to the bolt hole by a nut 4.
As shown in fig. 2, the trunnion seat protecting cover 1 is formed by sequentially welding a plurality of sections of steel cylinders with gradually decreasing cylinder diameters, and a plurality of bolt holes matched with the rotary bolt columns 2 are uniformly arranged at the edge of the cylinder with the largest bottom of the trunnion seat protecting cover 1. Generally, the device is to be matched with four rotary bolt columns 2, so that 4 bolt holes are uniformly distributed in the circumferential direction of a cylinder body part with a larger diameter, and the device is matched with the rotary bolt columns 2.
In one embodiment, the wrench 3 is rectangular, and has a circular hole at one end, and is fixed to the end of the rotary bolt post 2.
When the bridge trunnion seat is not provided with a trunnion, the bridge trunnion seat and the shaft sleeve inside the bridge trunnion seat are in an idle state. At this time, the bridge trunnion seat and the shaft sleeve therein are provided with the bridge trunnion seat protection device, which can prevent external objects from entering the bridge trunnion seat, and can provide a certain supporting effect for the bridge trunnion seat or the shaft sleeve when the bridge trunnion seat or the shaft sleeve is suddenly damaged by the outside, thereby preventing deformation to a certain extent and achieving the purpose of protecting the bridge trunnion seat.
The installation and working process of this embodiment is as follows:
1) Uniformly placing 4 rotary bolt columns 2 into the bridge frame trunnion seat;
2) The method comprises the steps that a trunnion seat protection cover 1 is arranged in a bridge trunnion seat, in the installation process, attention is paid to the fact that 4 rotary bolt columns 2 are arranged in 4 bolt column holes in the trunnion seat protection cover 1, and preliminary installation of the trunnion seat protection cover 1 is completed;
3) The nut 4 is arranged on the rotary bolt post 2, the nut 4 is screwed tightly gradually, so that the nut 4 is tightly clamped with the outer edge of a bolt post hole of the protecting cover, and finally, a clamping plate at the tail end of the bolt post is tightly clamped with the inner edge of a shaft sleeve of the bridge trunnion seat, and a fixed clamping plate at the end part of the protecting cover 1 is tightly clamped with the outer edge of the shaft sleeve of the bridge trunnion seat;
