Description

Technical Field

[0001] This utility model relates to the field of port freight equipment technology, and in particular to a high-efficiency hoisting machine for port freight. Background Technology

[0002] In port cargo operations, hoists are typically used for loading and unloading cargo. The efficiency of cargo loading and unloading directly affects the port's operational capacity and economic benefits. In the actual use of traditional port hoists, workers usually fix the cargo to the hook, and the hoisting device then lifts the cargo and transports it to the cargo ship. Existing hoists are inefficient in use, which seriously restricts the improvement of cargo transportation efficiency.

[0003] For example, Chinese patent CN215287601U discloses a freight hoist, which includes a shell, a freight box, a power component, a main controller, a stroke detection component, and a control panel. The main controller is connected to the power component, the stroke detection component, and the control panel. The shell is arranged longitudinally through the floors, and an automatic door is provided on each floor.

[0004] The existing hoist structure design and operation mechanism are relatively outdated. The process of lifting and unloading materials takes a long time. Common hoists require a relatively complex operation process when loading and unloading materials, which makes the overall loading and unloading speed unable to meet the growing freight demand of modern ports. In addition, traditional hoists rely on manual operation, especially the loading and unloading of materials, which requires real-time human intervention, increasing labor costs. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art and to propose a high-efficiency hoisting machine for port cargo transportation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency hoist for port cargo transportation, comprising a hoisting mechanism, the hoisting mechanism including a base, a rotating seat, a hoisting cylinder, a rotating arm, and an extension rod. A placement platform and a loading electric push rod are fixedly installed at one top end of the base. A loading plate is slidably installed at one top end of the placement platform, and the output end of the loading electric push rod is fixedly connected to the bottom of the loading plate. A loading mechanism is installed at one end of the extension rod. The loading mechanism includes a fixed plate, a mounting rod, a base plate, a screw motor, a threaded rod, a storage plate, and a unloading electric push rod. Scissor telescopic frames are symmetrically arranged on both sides of the base plate. A movable plate is rotatably installed between the bottoms of the scissor telescopic frames on both sides, and the tops of the scissor telescopic frames on both sides are rotatably installed with the bottom of the storage plate. The threaded rod passes through the movable plate, and the outer wall of the threaded rod engages with the inner thread of the movable plate. The unloading electric push rod is fixedly installed at one top end of the storage plate, and the output end of the unloading electric push rod is fixedly connected to the unloading plate.

[0007] Preferably, the output end of the lead screw motor is fixedly connected to one end of the threaded rod, and the base plate is welded to the top of the fixed plate.

[0008] Preferably, the fixing plate is symmetrically welded with hanging rods on both sides, and the two ends of the mounting rod are respectively welded to one end of the two hanging rods.

[0009] Preferably, the rotating seat is fixedly installed at one end of the base away from the placement platform, and the bottom of the support frame is fixedly installed on the top of the rotating seat.

[0010] Preferably, one end of the rotating arm is rotatably mounted to the top of the support frame, and an extension cylinder is fixedly mounted on the top of the other end of the rotating arm.

[0011] Preferably, the extension rod is sleeved on one end of the rotating arm, and the output end of the extension cylinder is fixedly connected to the top of the extension rod, and the two ends of the mounting rod are rotatably mounted to one end of the extension rod.

[0012] Preferably, the lifting cylinder is rotatably mounted on the outside of the support frame, and the output end of the lifting cylinder is rotatably mounted to one end of the rotating arm.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by placing the goods on the top of the placement platform, the loading electric push rod drives the loading plate to move, pushing the goods to the top of the placement plate. Through the cooperation of the lifting mechanism and the loading mechanism, the goods are lifted upward and transported to the unloading position. When the loading mechanism is lifted upward or lowered downward, it can maintain a vertical state under its own weight to prevent the goods from falling. When the goods are transported to the unloading position, the unloading electric push rod automatically pushes the goods off the placement plate through the unloading plate, thereby completing the automatic unloading process of the goods. This hoist, through the combination of the loading electric push rod and the unloading electric push rod, eliminates the need for a relatively complex action process when loading and unloading materials, and achieves the purpose of automatic loading and unloading, reducing manual operation links and lowering labor costs.

[0015] 2. In this utility model, the hoist realizes the automated operation of loading and unloading. The operator only needs to perform simple operations on the control panel to complete the loading and unloading process. The lifting mechanism and the loading mechanism work together to quickly and stably lift and unload goods, significantly shortening the loading and unloading time and effectively meeting the ever-increasing freight demand of the port.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-4As shown, this utility model provides a high-efficiency hoist for port cargo transportation, including a hoisting mechanism 1. The hoisting mechanism 1 includes a base 11, a rotating seat 12, a hoisting cylinder 14, a rotating arm 15, and an extension rod 17. A placement platform 3 and a loading electric push rod 4 are fixedly installed at one end of the top of the base 11. A loading plate 5 is slidably installed at one end of the top of the placement platform 3, and the output end of the loading electric push rod 4 is fixedly connected to the bottom of the loading plate 5. A loading mechanism 2 is installed at one end of the extension rod 17. The loading mechanism 2 includes a fixed plate 21, a mounting rod 22, a base plate 24, a screw motor 25, a threaded rod 26, a storage plate 29, and a unloading electric push rod 210. Scissor telescopic frames are symmetrically arranged on both sides of the base plate 24. 28. A movable plate 27 is rotatably installed between the bottoms of the two scissor telescopic frames 28, and the tops of the two scissor telescopic frames 28 are rotatably installed with the bottom of the storage plate 29. A threaded rod 26 is set through the movable plate 27, and the outer wall of the threaded rod 26 is threadedly engaged with the inner side of the movable plate 27. A loading electric push rod 210 is fixedly installed at one end of the top of the storage plate 29, and the output end of the loading electric push rod 210 is fixedly connected to the loading plate 211. The output end of the screw motor 25 is fixedly connected to one end of the threaded rod 26, and the base plate 24 is welded to the top of the fixed plate 21. Hanging rods 23 are symmetrically welded on both sides of the fixed plate 21, and the two ends of the mounting rod 22 are respectively welded to one end of the two hanging rods 23.

[0024] The specific setup and function of this embodiment are described below: When goods need to be loaded, the operator places the goods on top of the placement platform 3 (e.g., Figure 4 As shown, the placement platform 3 is flush with the shelf 29. The electric loading push rod 4 is activated, moving the loading plate 5 and pushing the goods to the top of the shelf 29, achieving automatic loading. At this time, the lead screw motor 25 is activated, driving the threaded rod 26 to rotate, causing the two side scissor telescopic frames 28 to extend upwards, pushing the shelf 29 and goods upwards to the top. Figure 3 After the state shown, the lifting cylinder 14 is activated, which drives the rotating arm 15 to rotate upward. At the same time, the extension cylinder 16 can drive the extension rod 17 to extend outward and become longer according to the unloading position. The rotating seat 12 can drive the support frame 13, the rotating arm 15, the extension rod 17 and the loading mechanism 2 to change direction, thereby lifting the loading mechanism 2 and the goods upward and transporting them to the unloading position. Since the mounting rod 22 of the loading mechanism 2 is rotatably installed at one end of the extension rod 17, the loading mechanism 2 can remain vertical under its own weight when it is lifted upward or lowered downward, thus preventing the goods from falling.

[0025] When the goods are transported to the unloading position, the unloading electric push rod 210 is activated. The unloading electric push rod 210 automatically pushes the goods off the storage plate 29 via the unloading plate 211, thereby completing the automatic unloading process. After unloading, the operator controls the elevator to return to the initial position through the control panel, ready for the next loading and unloading operation. The elevator, through the combination of the loading electric push rod 4 and the unloading electric push rod 210, eliminates the need for a relatively complex action process when loading and unloading materials, and achieves the purpose of automatic loading and unloading, reducing manual operation and lowering labor costs.

[0026] Example 2: Figures 1-3 As shown, the rotating seat 12 is fixedly installed at one end of the base 11 away from the placement platform 3. The bottom of the support frame 13 is fixedly installed at the top of the rotating seat 12. One end of the rotating arm 15 is rotatably installed with the top of the support frame 13, and an extension cylinder 16 is fixedly installed at the top of the other end of the rotating arm 15. An extension rod 17 is sleeved on one end of the rotating arm 15, and the output end of the extension cylinder 16 is fixedly connected to the top of the extension rod 17. Both ends of the mounting rod 22 are rotatably installed with one end of the extension rod 17. The lifting cylinder 14 is rotatably installed on the outside of the support frame 13, and the output end of the lifting cylinder 14 is rotatably installed with one end of the rotating arm 15.

[0027] The overall effect of this embodiment is as follows: The hoist is based on an advanced PLC technology to build a control system. The hoist's operating data is collected in real time by sensors and transmitted to the PLC for analysis and processing. The PLC automatically controls the various actions of the hoist according to the preset program and algorithm, realizing the automated operation of the hoist. Operators can remotely control the hoist and set parameters through the operation panel, which is convenient for operators to use.

[0028] The hoist has achieved automated operation. Operators can complete the loading and unloading process of goods by simply operating the control panel. The hoisting mechanism 1 and the loading mechanism 2 work together to quickly and stably lift and unload goods, significantly shortening the loading and unloading time and effectively meeting the port's growing freight demand.

[0029] The operating method and working principle of this device are as follows: The operator places the goods on the top of the placement platform 3. The electric push rod 4 moves the loading plate 5, pushing the goods to the top of the storage plate 29. At this time, the screw motor 25 drives the threaded rod 26 to rotate, causing the scissor telescopic frames 28 on both sides to unfold upwards, pushing the storage plate 29 and the goods upwards. Figure 3After the state shown, the lifting cylinder 14 is activated, which drives the rotating arm 15 to rotate upward. At the same time, the extension cylinder 16 drives the extension rod 17 to extend outward and become longer according to the unloading position. The rotating seat 12 can drive the support frame 13, the rotating arm 15, the extension rod 17 and the loading mechanism 2 to change direction, thereby lifting the loading mechanism 2 and the goods upward and transporting them to the unloading position. When the loading mechanism 2 is lifted upward or lowered downward, it can maintain a vertical state under its own gravity to prevent the goods from falling.

[0030] When the goods are transported to the unloading position, the unloading electric push rod 210 automatically pushes the goods off the storage plate 29 via the unloading plate 211, completing the automatic unloading process. After unloading, the operator controls the hoist to return to the initial position via the control panel, ready for the next loading and unloading operation. The hoist achieves automatic loading and unloading by combining the loading electric push rod 4 and the unloading electric push rod 210, reducing labor costs. At the same time, it realizes the automated operation of the hoist. The operator only needs to perform simple operations on the control panel to complete the loading and unloading process. The lifting mechanism 1 and the loading mechanism 2 work together to quickly and stably lift and unload goods.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
