Description

Technical Field

[0001] This invention relates to the field of hatch cover installation technology, specifically a hatch cover end hinge base positioning fixture. Background Technology

[0002] Hatch covers for dry cargo transport vessels such as bulk carriers, wood chip carriers, and multipurpose vessels are mostly folding hatch covers. Folding hatch covers generally consist of two cover plates, also known as single-pair folding covers. The cover plates are connected by hinges. On the active cover plate near the hatch end, there is a pair of hinged arms that extend out of the hatch. The hinged arms connect the cover plate to the deck through the end hinge. Rollers are set on both sides of the driven cover plate end. During the opening process, the active cover plate rotates around the end hinge axis and pulls the rollers of the driven cover plate onto the track until the two cover plates fold together and are stored outside the hatch end, above the panel of the hatch coaming.

[0003] The hatch cover hinge requires positioning during installation and adjustment. Because the base of the hinge is heavy, workers must stand on an A-frame ladder and repeatedly move the positioning plate up and down to "align" it, affecting the efficiency of hinge base adjustment. Traditional positioning fixtures are also quite bulky, weighing approximately eight kilograms. When operators stand on an A-frame ladder and move the positioning plate up and down, it not only increases their workload and reduces work efficiency, but also poses a risk of falls and injuries. Therefore, a new hatch cover hinge base positioning fixture needs to be designed to address these issues. Summary of the Invention

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a positioning fixture for the hinge base of the hatch cover, which has the following features:

[0018] Beneficial effects:

[0019] 1. The hatch cover hinge base positioning fixture allows the operator to place the mounting base plate on the on-site hinge base by holding the handle and aligning it with the marked positioning line. Then, based on the distance between the mounting base plate and the hatch cover ear plate, the corresponding dimensions are calculated. The square extension tube is then adjusted in height from inside the square sleeve steel tube. Once the appropriate height is reached, the limit pin is inserted into the adjustment hole to tighten and reinforce the square extension tube and the square sleeve steel tube. This eliminates the need to stand on an A-frame ladder and hold the positioning plate for alignment, reducing the labor intensity of construction and eliminating the need for operators to climb ladders, thus reducing safety risks during construction.

[0020] 2. This hatch cover hinge base positioning fixture uses an electromagnetic switch to open the electromagnetic coil inside the electromagnetic box, causing the magnetic block to generate magnetic attraction and secure it to the hinge base at the field end. The rear end of the mounting plate can rotate a rotating rod, causing the small and large suction cups at the lower end to move downwards and adhere to the hinge base at the field end, generating an adsorption force to reinforce the rear end of the mounting plate, making the hinge base and fixture a whole. This ensures the stability of the positioning fixture during operation. The hinge base at the field end is adjusted by checking whether the outer end line of the square extension tube is aligned with the center line of the hatch cover ear plate. This fixture not only meets the hinge positioning accuracy requirements, but is also simple and easy to operate, and convenient to install and disassemble. Attached Figure Description

The mounting base plate 101 is made of an 8mm thick steel plate. The handle 102 is welded to the middle of the upper end of the mounting base plate 101. The handle 102 has a mounting hole 103 on its rear side. The upper opening of the mounting hole 103 is smaller, and the lower opening is larger. The perforated block 104 is welded to the front side of the handle 102. A threaded hole is provided in the middle of the perforated block 104. A rubber pad 105 is provided at the lower end of the mounting base plate 101. The rubber pad 105 is adhered to the lower end of the mounting base plate 101. Holes are pre-drilled at the positions where the rubber pad 105 contacts the mounting hole 103 and the threaded reinforcement hole 106, and the size of the pre-drilled holes is the same as that of the mounting hole 103 and the threaded reinforcement hole 106. Threaded reinforcement holes 106 are provided on the front side of the perforated block 104. The threaded reinforcement holes 106 are symmetrically distributed. The design of the threaded reinforcement holes 106... It can interact with the fixing screws on the upper end of the fixed base 201 to reinforce the fixed base 201 and improve its stability; the magnetic fixing component 3 includes an electromagnetic box 301, an electromagnetic switch 302, a magnet 303, a fixing stud 304, and a fixing nut 305. An electromagnetic coil is installed inside the electromagnetic box 301. The electromagnetic coil is powered by a battery and generates a strong magnetic attraction force. An electromagnetic switch 302 is threaded on the middle left side of the outer end of the electromagnetic box 301. The electromagnetic switch 302 interacts with the screws inside the electromagnetic box 301. The electromagnetic coils are electrically connected. A magnet 303 is clamped and installed at the lower end of the electromagnetic box 301. The magnet 303 is designed to attract and fix the fixture, so that the hinge base and the fixture form a whole and are reinforced. The magnet 303 is electrically connected to the electromagnetic coil inside the electromagnetic box 301. A fixing stud 304 is welded and reinforced on the right side of the outer end of the electromagnetic box 301. A fixing nut 305 is threaded on the right side of the outer end of the fixing stud 304. The threads of the fixing stud 304 and the fixing nut 305 are matched.

[0030] In this invention, such as Figure 5As shown, the suction cup reinforcement assembly 4 includes a mounting sleeve 401, a limiting ring 402, a rotating rod 403, a small suction cup 404, and a large suction cup 405. The inner side of the upper end of the mounting sleeve 401 is adapted to the lower end of the limiting ring 402. The limiting ring 402 is fitted onto the upper end of the mounting sleeve 401. The limiting ring 402 is integrally cast from a larger steel pipe and a smaller steel pipe at the bottom, forming a sleeve that is larger at the top and smaller at the bottom. The inside is a threaded hollow structure. The rotating rod 403 is threaded onto the inner side of the upper end of the limiting ring 402. The screw-on installation between 02 and the rotating rod 403 allows for quicker disassembly. The lower end of the rotating rod 403 is threadedly connected to a small suction cup 404, and the lower end of the small suction cup 404 is equipped with a large suction cup 405. The small suction cup 404 and the large suction cup 405 are an integrated structure, which is shaped like a large ring containing a small ring. The connection end of the large ring containing the small ring is sealed, similar to the toilet suction cups in existing technology, which also contain a small toilet suction cup inside during manufacturing. The small suction cup 404 and the large suction cup 405 are made of rubber and are cast in an integrated mold.

[0031] During operation: the scribing error during tooling use is ±1m, and the tooling edge line is aligned with the base scribing line with a tolerance of ±1mm.

[0032] In summary, the positioning fixture for the hatch cover hinge base is used in the following steps: During operation, the operator holds the handle 102 and places the mounting base 101 onto the hinge base at the site end, aligning it with the marked positioning line. Then, based on the distance between the mounting base and the hatch cover lug, the corresponding dimensions are calculated. The square extension tube 203 is then adjusted in height from inside the square sleeve steel tube 202. Once the appropriate height is reached, the limit pin 206 is inserted into the adjustment hole 204 to tighten and reinforce the square extension tube 203 and the square sleeve steel tube 202. Below, the electromagnetic switch 302 activates the electromagnetic coil inside the electromagnetic box 301, causing the magnetic block 303 to generate magnetic attraction and secure it to the hinge base at the site end. The rear end of the mounting base plate 101 can rotate the rotating rod 403, which drives the small suction cup 404 and the large suction cup 405 at the lower end to move downwards and adhere to the hinge base at the field end to generate an adsorption force, thereby reinforcing the rear end of the mounting base plate 101 and making the hinge base and the tooling form a whole. This ensures the stability of the positioning tooling during operation. The hinge base at the field end is adjusted by checking whether the outer end line of the square extension tube 203 is aligned with the center line of the hatch cover ear plate. While the tooling positioning accuracy meets the hinge positioning requirements, the labor intensity of construction is reduced, and operators no longer need to climb ladders to work, reducing the safety risks generated during construction. The tooling is simple to operate and easier to disassemble and install.
