Description

Technical Field

[0001] This utility model belongs to the field of marine equipment maintenance technology, and specifically relates to a detachable and adjustable rotating marine equipment maintenance device. Background Technology

[0002] A ship needs to be equipped with hundreds or thousands of pieces of equipment, especially some large power facilities. Most of these pieces of equipment are made into unit rooms and arranged in corresponding positions on the ship. After the ship has been in operation for a period of time, the components of these pieces of equipment will need to be removed for maintenance. However, due to space limitations and the strength limitations of the equipment unit rooms, many pieces of equipment cannot be equipped with maintenance lifting clamps or are set in unreasonable positions, which cannot meet the requirements for routine maintenance removal and restoration.

[0003] Traditionally, for equipment with relatively ample space, several transfer clamps are welded to the structure above the equipment. However, each operation requires working at height using an A-frame ladder and multiple manual or electric hoists to access the equipment for maintenance. This involves handling a large number of parts and is cumbersome. It is also only suitable for equipment without individual unit roofs. For equipment with unit roofs, the parts requiring maintenance inside remain inconvenient to move and restore. For equipment with unit roofs, hydraulic forklifts (with counterweights and extension poles) are currently used to access the parts requiring maintenance. However, moving the forklift to the equipment location requires additional auxiliary tools, such as thresholds or ramps. Some equipment unit roofs are located in corners, inaccessible to forklifts due to limited travel space, thus failing to achieve the goal of rapid equipment maintenance. Furthermore, equipping hydraulic forklifts is expensive.

[0004] In summary, there is currently no universal maintenance device that meets the needs of various types of marine equipment; moreover, shipowners frequently raise similar equipment maintenance issues during actual ship construction; there is an urgent need for a maintenance device that is easy to use, widely applicable, low-cost, and easy to store. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a detachable and adjustable rotating marine equipment maintenance device that is lightweight, easy to operate, detachable, convenient to store, occupies little space, and is low in cost.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A detachable and adjustable rotating marine equipment maintenance device includes a first support, a lifting beam, and a second support. Both the first and second supports are vertically arranged. The upper end of the first support is rotatably connected to the first end of the lifting beam, and the second end of the lifting beam is detachably connected to the upper end of the second support. In use, the lower end of the first support is detachably connected to a steel base inside the equipment room, the second end of the lifting beam is located outside the equipment room, and the second support is rotatably arranged outside the equipment room. The marine equipment to be maintained is hooked onto the lifting beam and slides from the first end of the lifting beam to the second end of the lifting beam.

[0008] Furthermore, a sliding chain is slidably connected to the lifting beam, and a hand chain hoist is connected to the lower part of the sliding chain. The equipment to be repaired is connected to the hand chain hoist.

[0009] Furthermore, the first support is a circular tube support, and the second support is a circular tube lifting beam. The outer diameter of the circular tube lifting beam is smaller than the inner diameter of the circular tube support. The first end of the circular tube lifting beam is bent vertically downward. Multiple sets of pin holes are provided on opposite sidewalls of the first end of the circular tube lifting beam. The multiple sets of pin holes are spaced apart along the axial direction of the first end of the circular tube lifting beam. In use, the first end of the circular tube lifting beam is inserted into the circular tube support and positioned by fixing pins inserted into the pin holes.

[0010] Furthermore, an adjusting pad is provided at the first end of the circular tube lifting beam, and the adjusting pad can slide axially along the first end of the circular tube lifting beam.

[0011] Furthermore, a pad is fixed at the lower end of the circular tube support, and multiple screw holes are symmetrically provided on the pad. The lower end of the circular tube support is detachably connected to the steel base plate inside the equipment room by bolts.

[0012] Furthermore, a lifting beam elbow plate perpendicular to its axial direction is provided on the side wall of the second end of the circular tube lifting beam. Multiple screw holes are spaced from bottom to top on the lifting beam elbow plate. A support elbow plate is vertically provided on the upper side wall of the second support. Multiple screw holes are spaced from vertical to top on the support elbow plate. The screw hole spacing on the lifting beam elbow plate is the same as the screw hole spacing on the support elbow plate. The second end of the circular tube lifting beam is detachably connected to the second support by bolts passing through the screw holes.

[0013] Furthermore, the longitudinal section of the lifting beam elbow plate is a right-angled trapezoid, and its larger right-angle side is fixedly connected to the circular tube lifting beam; an anti-detachment pin is provided at the second end of the circular tube lifting beam, the anti-detachment pin is located on the side of the lifting beam elbow plate away from the first end, and the length of the anti-detachment pin is greater than the outer diameter of the circular tube lifting beam.

[0014] The anti-detachment pin is an additional safety feature to prevent the second end of the lifting beam from detaching from the U-shaped groove due to uneven or excessive force, loose bolts at the second end, or only one bolt being in place.

[0015] Furthermore, the second support includes a triangular support frame, with an intermediate support extending vertically from its bottom edge to above its upper included angle in the middle of the triangular support frame. The support elbow plate is located on the side of the intermediate support opposite to the circular tube support. Multiple U-shaped grooves with their center lines perpendicular to the intermediate support are provided at equal intervals along its axial direction on the upper part of the intermediate support. The multiple U-shaped grooves are located above the support elbow plate. The distance between two adjacent U-shaped grooves is equal to the distance between two adjacent screw holes on the lifting beam elbow plate. The width of the U-shaped groove is greater than the outer diameter of the circular tube lifting beam and less than the length of the anti-detachment pin.

[0016] The U-shaped groove acts as a stop when the lifting beam is at different heights, and the height of adjacent U-shaped grooves is equal to the bolt hole spacing. The U-shaped groove also bears a portion of the force.

[0017] Furthermore, multiple casters are connected to the bottom of the triangular support frame, and the multiple casters are connected to the triangular support frame by bolts.

[0018] This utility model's detachable and adjustable rotating marine equipment maintenance device is simple to operate, highly reliable, lightweight, and practical, with a wide range of applications. It is easy to operate, disassemble, store, and occupy little space, and has low cost. Its application on ships currently under construction has been recognized by ship owners, proving the practicality, convenience, and rationality of this design. Attached Figure Description

In use, the lower end of the first support is detachably connected to a steel base inside the equipment room, the second end of the lifting beam is located outside the equipment room, and the second support is rotatably arranged outside the equipment room. A sliding chain 9 is slidably connected to the lifting beam, and a hand chain hoist 8 is connected to the lower part of the sliding chain 9. The equipment to be maintained is connected to the hand chain hoist 8 and slides from the first end of the lifting beam to the second end of the lifting beam.

[0027] Understandably, the first support is fixed inside the equipment room, and the lifting beam extends from the equipment protection and connects to the second support. During use, the equipment to be repaired slides along the lifting beam from the equipment room to the outside. Because the lifting beam is rotatably connected to the first support, and the second support can move outside the equipment room, the lifting beam can be continuously rotated and moved according to the space inside the equipment room to move the equipment out. After repair, the operation is reversed to return the equipment to its original position. Finally, the lifting beam is disassembled and stored at a corner.

[0028] like Figures 1-5 As shown, in this embodiment, the first support is a circular tube support 1, and the second support is a circular tube lifting beam 3. The outer diameter of the circular tube lifting beam 3 is smaller than the inner diameter of the circular tube support 1. The first end of the circular tube lifting beam 3 is bent vertically downward. Multiple sets of pin holes are provided on opposite sidewalls of the first end of the circular tube lifting beam 3.

An adjusting pad 2 is provided through the first end of the circular tube lifting beam 3. The adjusting pad 2 can slide along the axial direction of the first end of the circular tube lifting beam 3. A pad 10 is fixed at the lower end of the circular tube support 1. Multiple screw holes are symmetrically provided on the pad 10. The lower end of the circular tube support 1 is detachably connected to the steel base plate in the equipment room by bolts.

[0029] A lifting beam elbow plate 11 perpendicular to its axial direction is provided on the side wall of the second end of the circular tube lifting beam 3. Multiple screw holes are provided on the lifting beam elbow plate 11 at intervals from bottom to top. A support elbow plate 12 is provided vertically on the upper side wall of the second support. Multiple screw holes are provided on the support elbow plate 12 at intervals along its vertical direction. The screw hole spacing on the lifting beam elbow plate 11 is the same as the screw hole spacing on the support elbow plate 12. The second end of the circular tube lifting beam 3 is detachably connected to the second support by bolts 6 passing through the screw holes.

[0030] The longitudinal section of the lifting beam elbow plate 11 is a right-angled trapezoid, with its larger right-angle side fixedly connected to the circular tube lifting beam 3. An anti-detachment pin 7b is inserted through the second end of the circular tube lifting beam 3. The anti-detachment pin 7b is located on the side of the lifting beam elbow plate 11 away from the first end, and its length is greater than the outer diameter of the circular tube lifting beam 3. In this embodiment, the length of the anti-detachment pin 7b is 30mm greater than the outer diameter of the circular tube.

[0031] When it is necessary to repair equipment such as motors inside the equipment room, fix the round tube support 1 to the steel base inside the equipment room with bolts 6, insert one end of the round tube lifting beam 3 into the round tube support 1, determine the position of the adjustment pad 10 according to the height of the equipment room and fix it with the fixing pin 7a; similarly adjust the corresponding height, connect the lifting beam elbow plate 11 on the round tube lifting beam 3 to the support elbow plate 12 with double bolts 6, and install the anti-detachment pin 7b at the same time.

[0032] Furthermore, the second support is a triangular support 4, including a triangular support frame 41. A central support 42 is provided in the middle of the triangular support frame 41, extending vertically from its bottom edge to above its upper included angle. The support elbow plate 12 is located on the side of the central support 42 opposite to the circular tube support 1. Multiple U-shaped grooves 421 with their center lines perpendicular to the central support 42 are provided at equal intervals along its axial direction on the upper part of the central support 42. These multiple U-shaped grooves 421 are located above the support elbow plate 12. The distance between two adjacent U-shaped grooves 421 is equal to the distance between two adjacent screw holes on the lifting beam elbow plate 11. The width of the U-shaped groove 421 is greater than the outer diameter of the circular tube lifting beam 3 and less than the length of the anti-detachment pin 7b. The U-shaped grooves 421 facilitate adjustment of the lifting beam height.

[0033] Furthermore, a plurality of casters 5 are connected to the bottom of the triangular support frame 41, and the plurality of casters 5 are connected to the triangular support frame 41 by bolts.

[0034] Understandably, the casters 5 are provided to facilitate the movement of the triangular support frame 41.
