Description

Technical Field

[0001] This invention relates to the field of ship equipment technology, and in particular to a portable lifting base for hatch covers. Background Technology

[0002] In some storage compartments, equipment rooms, and sail and cable compartments on ships, the upper deck is generally equipped with hatch covers. These hatch covers mainly serve as escape routes for personnel, entrances and exits, and cargo entrances and exits. The hatch is the only vertical passage between the interior of the ship and the deck. Fixed cranes are limited by their lifting angle and have difficulty accurately aligning with the edge of the hatch. Portable cranes, with their small size and flexible deployment advantages, can achieve efficient transfer of materials between the interior of the ship and the deck.

[0003] Existing portable sling bases for hatch covers are either tripod-type or welded bolt-mounted bases. Tripod-type mobile bases require a relatively large unfolding space and additional securing methods; welded bolt-mounted bases, being immovable, must be pre-installed at all possible locations, resulting in material waste and encroaching on the already limited and valuable space on the hull when the portable sling is not installed. Summary of the Invention

[0004] In view of the above-mentioned problems existing in the prior art, the present invention provides a portable lifting base for hatch covers to solve the technical problems of large space occupation, material waste and space occupation of the ship hull in the prior art.

A fixed cylinder, which is vertically fixed to the cantilevered section of the supporting base plate, and has an opening at the top of its cylinder; The bottom column of the portable crane is inserted into the fixed cylinder and is connected and fixed to the fixed cylinder through a limiting component.

[0006] In one embodiment, the limiting component includes, A positioning pin passes through the fixed cylinder and the bottom column of the portable hoist, and connects and fixes the two. A limiting bolt is inserted into the fixed cylinder, with its inner end abutting against the bottom column of the portable crane to prevent the bottom column of the portable crane from shaking.

[0007] In one embodiment, a set of positioning pins is provided, and the positioning pins are located at the bottom of the fixed cylinder.

[0008] In one embodiment, a set of limiting bolts is provided, which are located at the top of the fixed cylinder, and the limiting bolts abut the bottom column of the portable crane against the inner wall of the fixed cylinder.

[0009] In one embodiment, it also includes, Several elbow plates are fixedly disposed between the supporting base plate and the outer wall of the fixed cylinder.

[0010] In one embodiment, the support base plate is further provided with a hollowed-out second clearance portion, which is located above the hatch coaming and communicates with the first clearance portion.

[0011] In one embodiment, the cross-section of the fixing cylinder is circular, and its inner diameter is 6-8 mm larger than the outer diameter of the bottom column of the portable crane.

[0012] In one embodiment, the width of the cantilevered section of the supporting base plate gradually narrows from the inside to the outside.

[0013] In one embodiment, the outer convex edge of the supporting base plate at the fixed cylinder is configured with a rounded chamfer structure.

[0014] Compared with the prior art, the beneficial effects of the portable lifting base for hatch covers provided by the embodiments of the present invention are as follows: the embodiments of the present invention have a simple structure and are easy to disassemble.

[0020] It should also be understood that although this application has been described with reference to some specific examples, those skilled in the art can certainly implement many other equivalent forms of this application, which have the features described in the claims and are therefore all within the scope of protection defined herein.

[0021] The above and other aspects, features and advantages of this application will become more apparent when taken in conjunction with the accompanying drawings and in view of the following detailed description.

[0022] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0023] The principles and features of the present invention are described below with reference to the accompanying drawings. The embodiments described are for illustrative purposes only and are not intended to limit the scope of the invention. The following description, in conjunction with... Figure 1-4 The preferred embodiments of the present invention will be described in further detail below: like Figure 1-4 As shown, an embodiment of the present invention provides a portable lifting base for a hatch, comprising: A support base plate 1, one side of the support base plate 1 is attached to the top of the hatch coaming 9, and the other side of the plate extends out of the edge of the hatch coaming 9 in a cantilevered manner. The part of the plate corresponding to the hatch inside the hatch coaming 9 is provided with a hollow first clearance part 2, and the plate is provided with bolt holes 3 at the position of the fixing studs of the hatch coaming 9. A fixed cylinder 4 is vertically fixed to the cantilever section of the supporting base plate 1, and the top of the cylinder is open. The bottom column of the portable crane 8 is inserted into the fixed cylinder 4 and is connected and fixed to the fixed cylinder 4 through the limiting component.

[0024] In one embodiment, the limiting component includes, Positioning pin 6, which passes through the bottom column of the fixed cylinder 4 and the portable crane 8 and connects and fixes the two. The number and setting position of positioning pin 6 are calculated and determined according to the hoisting requirements. The limiting bolt 7 is inserted through the fixed cylinder 4, and its inner end abuts against the bottom column of the portable crane 8 to prevent the bottom column of the portable crane 8 from shaking.

[0025] In one embodiment, to ensure the stability of the portable crane and for ease of installation, a set of positioning pins 6 is provided, and the positioning pins 6 are located at the bottom of the fixed cylinder 4. Furthermore, a set of limiting bolts 7 is provided, and the limiting bolts 7 are located at the top of the fixed cylinder 4. The limiting bolts 7 abut the bottom column of the portable crane 8 against the inner wall of the fixed cylinder 4. By setting fixing points at both ends of the fixed cylinder 4, the stability of the portable crane can be improved as much as possible with fewer fixing points.

[0026] In one embodiment, the base further includes a plurality of elbow plates 5, which are fixedly disposed between the supporting base plate 1 and the outer wall of the fixed cylinder 4. The plurality of elbow plates 5 are arranged at circumferential intervals within a certain angle, and their plates are welded and fixed to the supporting base plate 1 and the fixed cylinder 4 respectively to ensure the overall strength of the base.

[0027] In one embodiment, the support base plate 1 is also provided with a hollowed-out second clearance part 10. The second clearance part 10 is located above the hatch coaming 9 and communicates with the first clearance part 2. The second clearance part 10 can cut off the part of the support base plate 1 that does not need to be bolted, which can reduce the amount of material used and the number of installation and dismantling bolts, thereby reducing the difficulty of installation and dismantling.

[0028] In one embodiment, the fixed cylinder 4 has a circular cross-section, and its inner diameter is 6-8 mm larger than the outer diameter of the bottom column of the portable crane 8. This facilitates the installation of the portable crane 8 and ensures that the portable crane 8 will not tilt significantly after being fixed, thus ensuring the safety of the hoisting.

[0029] In one embodiment, the width of the cantilever section of the supporting base plate 1 gradually narrows from the inside to the outside. By removing the excess portion of the supporting base plate 1, space occupation and material waste can be reduced.

[0030] In one embodiment, the outer protruding edge of the supporting base plate 1 at the fixed cylinder 4 is set with a rounded chamfer structure to prevent the protruding plate from causing bumps and injuries to the workers.

[0031] In one embodiment, considering that the lifting capacity of the portable crane 8 at the hatch cover is within 2t, the thickness of the supporting base plate 1 should be set to about 10-14mm.

[0032] In one embodiment, in order to improve the stability of the base, the bottom end of the fixed cylinder 4 can penetrate the support base plate 1 to ensure that the bottom end of the portable crane 8 can be supported on the deck, thereby sharing part of the load and avoiding deformation of the hatch coaming 9. Of course, on this basis, a large-area load-bearing base can also be added to the bottom end of the portable crane 8 in a sleeve manner to avoid damage to the deck due to stress concentration.

[0033] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
