For the entry of equipment into the ship's engine room area, it is usually necessary to erect scaffolding from the bottom of the dock to the opening position of the process perforation plate after the ship enters the dock, and then dismantle the scaffolding to hoist the equipment into the dock. After the hoisting is completed, scaffolding is erected again to reinstall the process perforation plate. The scaffolding erection project is large in scale and repeated, which is difficult and requires a lot of various steel materials. The construction period for the process perforation plate of the equipment in the dock is long, the dock occupies a long time, and the dock utilization rate is low. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the described embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by a person of ordinary skill in the art to which this application pertains.

[0029] like Figures 1 to 12As shown, a tooling for entering equipment in a ship dock includes a universal propeller dismantling tooling frame 101, a counterweight 102 placed at the bottom of the universal propeller dismantling tooling frame 101, the weight of which should be sufficient to maintain the balance of the tooling during operation, a connecting support 103, one end of which is welded to the top of the universal propeller dismantling tooling frame 101 and the other end of which is welded to an equipment entry process perforated plate cut from the ship's hull plate, the strength of which should be sufficient to prevent deformation during operation, and a scaffolding 104 arranged with the universal propeller dismantling tooling frame 101 and the connecting support 103 as fulcrums, the scaffolding 104 covering the equipment entry process perforated plate. This application utilizes an existing universal propeller dismantling fixture 101 to perform preliminary preparations before the ship enters the dock. These preparations include installing a counterweight 102 and a connecting support 103 that matches the process perforation plate, and scaffolding 104 arranged with the universal propeller dismantling fixture 101 and the connecting support 103 as fulcrums. The scaffolding 104 should cover the process perforation plate for the equipment entering the dock. After the preparations are completed, the ship enters the dock, and a hydraulic lifting flatbed transport vehicle transports the equipment for entering the dock to the process perforation plate construction area behind the ship's pier. The hydraulic lifting flatbed transport vehicle's movement and lifting stroke are used to position and align the connecting support 103 installed on the propeller dismantling fixture with the process perforation plate on the outer plate of the equipment entering the dock. During installation, the lifting stroke of the hydraulic jacking flatbed transport vehicle should meet the range of the process perforated plate to be supported. After the construction personnel pass through the steps, handrails, and straight ladder passage on the ship's propeller dismantling frame to the scaffolding, they weld the support connection points that fit with the process perforated plate of the equipment entry compartment. Then, the range of the process perforated plate of the equipment entry compartment is defined and flame-cut out the process perforated plate of the equipment entry compartment. Then, the hydraulic jacking flatbed transport vehicle is used to transport the process perforated plate of the equipment entry compartment and the tooling for equipment entry in the ship dock as a whole out of the equipment entry compartment area, leaving enough space for the equipment entry compartment. After the equipment is hoisted into the compartment, the hydraulic jacking flatbed transport vehicle is used to return the process perforated plate to its pre-removal state, and the process perforated plate can be quickly assembled, welded, and transported back to the hull plate. After the process perforated plate is reinstalled, the connection support points between the ship's propeller dismantling fixture and the outer plate equipment's access process perforated plate are removed. Then, the relevant scaffolding 104, connecting supports 103, and counterweights 102 are removed, restoring the ship's propeller dismantling fixture 101 to its original function. This application enables rapid dismantling and reinstallation, saving the ship's docking period and reducing dock usage costs.

[0030] Specifically, the connecting support 103 includes two diagonal braces, one end of which is welded to the top two bases of the universal propeller dismantling fixture 101, and the other end of which points towards the equipment inlet process orifice plate; and two horizontal braces, one end of which is welded to the two upright supports on the top of the universal propeller dismantling fixture 101, and the other end of which points towards the equipment inlet process orifice plate. The combination of the diagonal and horizontal braces provides better support strength and stability.

[0031] Specifically, a reinforcing rod connects the two diagonal braces and the two horizontal braces, further enhancing the support strength and stability.

[0032] Specifically, the other end of the connecting support 103 is welded to the outer plate profile of the perimeter of the equipment inlet process orifice plate, which can improve the convenience of process orifice plate construction.

[0033] Specifically, the counterweight 102 is a single unit, placed in the middle of the opposite side of the process orifice plate of the equipment, which can accommodate smaller process orifice plates and equipment entering the cabin.

[0034] Specifically, there are 1022 counterweights, placed at both ends on opposite sides of the process orifice plate entering the cabin, which can accommodate larger process orifice plates and cabin entry equipment.

[0035] Specifically, the counterweight 102 is welded to the bottom of the universal propeller disassembly fixture, which improves the stability of the counterweight 102. Specifically, the welding process includes preheating measures to reduce the temperature difference between the workpiece and the welding materials, thus avoiding instability caused by changes in stability.

[0036] Specifically, the welding process includes post-weld slow cooling measures, which can slow down the cooling rate of the welded joint and prevent weld cracking caused by instability changes.

[0037] The above description is merely an exemplary embodiment of this application and is not intended to limit the scope of protection of this application. The scope of protection of this application is determined by the appended claims.
