Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lifting technology, and in particular relates to a marine cargo lifting machine. Background Technology
[0002] Marine elevators mainly consist of a shaft, hall door, car, car rail, counterweight, counterweight rail, traction machine, cable system, and control system. Because there are many components to be installed in the shaft, and space needs to be reserved for the car and counterweight, the shaft occupies a large amount of space.
[0003] The hall doors of most existing elevators are located on the same side of the shaft. The space inside the same ship is relatively limited, and the spatial layout of each deck is different. This may result in limited space outside the door, making it difficult to load and unload cargo effectively.
[0004] Therefore, designing an elevator that allows for convenient multi-faceted layout of hall doors while occupying minimal space is a problem that professionals in this field need to solve. Summary of the Invention
[0005] The purpose of this utility model is to provide a marine cargo elevator. Through the design of the clearance cavity, it can be arranged on the highest deck of the ship. Similarly, the control cabinet and traction machine are installed in the clearance cavity, which reduces the space occupied by the hoistway. Furthermore, the side-opening maintenance door design can greatly reduce the space occupied by the elevator. At the same time, the position layout of the pulley block, car body lifting area, counterweight lifting area and pulley block improves the compactness of the elevator after assembly, further reducing the space occupied.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model is a marine cargo elevator, including a shaft, a car body, several outer hall doors and a control cabinet;
[0008] The top rear side of the shaft is provided with a relief cavity, the bottom surface of the relief cavity is the top deck surface, the bottom of the relief cavity is provided with a traction machine, the outside of the relief cavity is provided with an inspection door, and the top of the shaft is provided with a pulley block.
[0009] The hoistway consists of a car area and a counterweight area. Car rails are fixed at opposite corners in the car area, and counterweight rails are provided on both sides in the counterweight area.
[0010] The car body is a rectangular box. Except for the three sides near the counterweight, the car body is equipped with a manually operated lifting door panel. The opposite corners of the outer side of the car body are equipped with sliding shoes that are slidably connected to the car rail. The traction machine is connected to the car body through lifting cables and pulley blocks.
[0011] A counterweight is slidably connected between the two counterweight rails, and the counterweight is connected to the car body through a counterweight cable and a pulley system.
[0012] The outer hall door is located at the hoistway on the deck level, and the number of outer hall doors on the same deck level is set to 1-3. The outer hall door is located on three sides of the hoistway away from the counterweight rail side.
[0013] The shaft is equipped with several floor-stopping limiters, each of which is corresponding to the height of several outer hall doors on each floor. The top of the shaft is equipped with an extreme limiter.
[0014] The outer hall door is a single-sided hinged door. A button box is provided on the outer side of the hinge side of the outer hall door. A manual switch and a door limit switch are provided at the connection between the outer hall door and the shaft.
[0015] The control cabinet contains a processor and several control units. The traction machine, several button boxes, several floor stop limiters, extreme limiters, and several hall door limiters are all electrically connected to the processor.
[0016] Furthermore, the pulley system includes a first pulley group, a second pulley group, a third pulley group, and a fourth pulley group. The first pulley group is located directly above the traction machine, and the fourth pulley group is located directly above the car body. The second and third pulley groups are located on the side of the hoistway away from the counterweight rail and are respectively opposite to the first and fourth pulley groups. The lifting cable passes through the first, second, third, and fourth pulley groups in sequence and then connects to the top of the car body.
[0017] Furthermore, the second and third wheel sets are both horizontally guided wheel sets, while the first and fourth wheel sets are both vertically guided wheel sets.
[0018] Furthermore, a fifth wheel assembly is fixed to the top of the shaft, and the counterweight cable passes around the fifth wheel assembly and connects to the car body.
[0019] Furthermore, a first buffer device and a second buffer device are fixed at the bottom of the shaft, and the first buffer device and the second buffer device are respectively located directly below the car body and the counterweight.
[0020] Furthermore, the control cabinet is installed on the rear side inside the clearance cavity and does not interfere with the lifting cable.
[0021] This utility model has the following beneficial effects:
[0022] 1. This utility model, through the design of the clearance cavity, can be arranged at the highest deck of the ship's hull. Similarly, the control cabinet and traction machine are installed in the clearance cavity, reducing the space occupied by the hoistway. Furthermore, through the side-opening maintenance door design, when the car body is raised to the top of the hoistway, the main structure of the elevator is integrated near the clearance cavity, which is conducive to maintenance and repair, and can greatly reduce the space occupied by the elevator. At the same time, the position layout of the pulley block, car body lifting area, counterweight lifting area and pulley block improves the compactness of the elevator after assembly, further reducing space occupation.
[0023] 2. This utility model, through the setting of floor stop limit and extreme limit, can accurately control the stopping position of the car body and prevent the car body from exceeding the extreme height, thus ensuring safety. By designing manually openable external hall door and car door, the weight of the car body is reduced, lowering the cost of the elevator. At the same time, the hall door limit is set on the external hall door, which can be connected to the traction machine. When the door is open, the lifting and lowering control of the car body cannot be performed, greatly improving the safety of the elevator.
[0024] 3. This utility model, by designing a car body that can be opened and closed independently on three sides, and in conjunction with an outer hall door that can be installed arbitrarily on three sides of the hoistway, can adaptably arrange loading and unloading points according to usage requirements, thereby improving the efficiency of the elevator. It is suitable for transporting food, grain or other goods.
[0025] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
