Technical Field

[0001] The invention relates to the technical field of elevators, in particular to a single-door marine construction elevator. Background Art

[0002] The single-door marine construction elevator can quickly and efficiently complete the vertical transportation tasks of goods and personnel. Rapidly shuttling between the various levels of the ship greatly improves work efficiency. This is especially important for scenes such as material transportation and equipment hoisting during ship construction, as well as personnel embarking and disembarking, cargo loading and unloading during ship operations.

[0003] Traditional construction elevators have inlet and outlet doors, which are not practical for places with space constraints. In view of the limitations of the space inside the ship and the inconvenience caused by the design of the inlet and outlet doors of the traditional construction elevator, the specific reasons are: space constraints. Due to the compact space inside the ship, the inlet and outlet door design of the traditional elevator occupies additional space, which is not conducive to the internal layout of the ship. It is difficult to use the inlet and outlet doors separately, which limits the flexibility and efficiency of the elevator.

[0004] In addition, there is no suitable storage space for sundries and tools used in construction, which easily leads to disorder in the ship and increases safety hazards; for this reason, the present application proposes a single-door ship construction elevator. Summary of the invention

A plurality of support frames 15 are fixedly connected to the bottom of the moving plate 14. Moving wheels 16 are installed on the support frames 15. When the moving wheels 16 are in contact with the ground and the moving seat 1 leaves the ground, the moving seat 1 can be pushed to move the entire device, so that it can be moved to a desired position.

[0023] How to achieve that the moving wheel 16 is against the ground and the moving seat 1 is off the ground, the two threaded cylinders 17 are fixedly connected with transmission wheels 19, the two transmission wheels 19 are connected by a transmission belt 20, and also include a driving mechanism, the driving mechanism includes a driving shaft 23 that penetrates the moving seat 1 and is rotatably connected thereto, the threaded cylinder 17 is fixedly connected with a first bevel gear 21, the driving shaft 23 is fixed with a second bevel gear 22, the first bevel gear 21 is meshed with the second bevel gear 22, and the driving shaft 23 is fixedly connected with a handle 24; the staff manually turns the handle 24, the handle 24 The rotation drives the driving shaft 23 to rotate, the rotation of the driving shaft 23 drives the second bevel gear 22 to rotate, the rotation of the second bevel gear 22 drives the first bevel gear 21 to rotate, and the rotation of the first bevel gear 21 drives the threaded cylinder 17 to rotate. Under the transmission of the two transmission wheels 19 and the transmission belt 20, the two threaded cylinders 17 can rotate synchronously, so that the driving screw 18 can be moved downward, and then the moving plate 14 is driven downward, and finally the moving wheel 16 is against the ground. As the threaded cylinder 17 rotates, the moving seat 1 is finally separated from the ground, so that the entire device can be moved.

[0024] After moving to a suitable position, the staff can reverse the handle 24, so that the moving plate 14 and the moving wheel 16 can be stored in the guide groove 13, and finally the moving seat 1 is against the hull, and the moving seat 1 can stably support the entire device.

[0026] A lifting screw 4 is fixedly connected to the rotating column 31, and two guide columns 5 are fixedly connected to the moving seat 1. The outer sleeves of the two guide columns 5 are provided with two connecting blocks 6 that are slidably connected to them. The lifting screw 4 passes through the two connecting blocks 6 and is threadedly connected to them. The two connecting blocks 6 are fixedly connected with mounting plates 8, and the mounting plates 8 are fixedly connected with a lifting car 9. The connecting blocks 6 can be limited under the guidance of the two guide columns 5. Therefore, when the lifting screw 4 rotates, the two connecting blocks 6 can be moved upward or downward, and then the mounting plates 8 can be driven to move upward or downward, thereby driving the lifting car 9 to move up and down.

[0027] A car door 12 is installed on the lift car 9, one end of the car door 12 is hingedly connected to the lift car 9, and the other end of the car door 12 is connected to the lift car 9 through a lock, so that the car door 12 can be locked; wherein, a support platform 2 is fixed to the upper end of the moving seat 1, and the support platform 2 is located below the lift car 9, and the lift car 9 can be supported by the support platform 2.

A collection box 10 is fixedly connected to the L-shaped plate 25, and debris can be collected through the collection box 10. Since some debris is small and located at the bottom of the collection box 10, it is inconvenient to clean it. Therefore, the collection box 10 needs to be removed to facilitate the cleaning of the debris in the collection box 10.

[0029] To this end, a locking mechanism is provided, specifically, the locking mechanism includes a U-shaped block 29 fixed on the support block 11, a slider 33 is slidably connected in the U-shaped block 29, a plug rod 28 fixedly connected to the slider 33 is penetrated by a plug rod 28, a slot 27 is provided on the L-shaped plate 25, the plug rod 28 penetrates the support block 11 and is slidably connected thereto, the plug rod 28 is slidably connected in the slot 27, the other end of the plug rod 28 penetrates the U-shaped block 29 and is slidably connected thereto, a spring 30 is fixedly connected to the U-shaped block 29, the other end of the spring 30 is fixedly connected to the slider 33, and a hand pull block 32 is fixedly connected to the plug rod 28; the elastic force of the spring 30 is used to make the plug rod 28 tightly inserted in the slot 27, so that the L-shaped plate 25 can be locked in the mounting groove 26.

[0030] When the inside of the collection box 10 needs to be cleaned, the collection box 10 needs to be disassembled, that is, the L-shaped plate 25 needs to be disassembled. For this purpose, the staff pulls the hand pull block 32 by hand, and the movement of the hand pull block 32 drives the insertion rod 28 to move, and the insertion rod 28 moves out of the slot 27.
