Description

Technical Field

[0001] This utility model relates to the field of port lifting technology, and in particular to a novel platform lifting device for lifting port equipment-type cargo. Background Technology

[0002] Port equipment cargo hoisting refers to the process of vertically lifting, horizontally moving, and precisely placing port equipment and related cargo in port operation scenarios using various types of lifting machinery. Equipment cargo is one of the main types of cargo handled in port loading and unloading operations, mainly including engineering machinery, large equipment parts, and irregularly shaped equipment. Due to the rich variety and diverse shapes of equipment cargo, traditional hoisting operation processes face new challenges.

[0003] The new type of platform spreader for hoisting port equipment cargo is a device that connects port cranes to equipment cargo, enabling vertical lifting, horizontal movement, and precise placement of the cargo.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a novel platform lifting device for hoisting port equipment-type cargo, comprising a lifting platform 1, with a hoisting mechanism 2 fixedly connected to the outer walls of the lifting platform 1 for rapid hoisting, and a clamping mechanism 3 fixedly connected to the bottom of the outer walls of the hoisting mechanism 2 for securing the crane; the hoisting mechanism 2 includes lifting plates 201, which are fixedly connected to the left and right sides of the outer walls of the lifting platform 1, and a connecting plate 202 rotatably connected to the top of the outer walls of multiple lifting plates 201, with a threaded connection to the middle of the inner wall of the connecting plate 202. A lead screw 203 has a pin 204 penetrating through the top of its outer wall. A support plate 205 is fixedly connected to one side of the inner wall of the platform 1. A fixing component 206 is fixedly connected to the middle of the inner wall of the platform 1. The fixing component 206 includes a fixing frame 2061, which is fixedly connected to the middle of the inner wall of the platform 1. A fixing plate 2062 is fixedly connected to the top of the outer wall of the fixing frame 2061. A spring plate 2063 is rotatably connected to the adjacent side of the outer wall of the fixing plate 2062. A fixing groove 2064 is fixedly connected to the top of the outer wall of the spring plate 2063.

[0032] Specifically, when the port equipment cargo lifting platform is in operation, in the lifting mechanism 2 around the platform 1, the lifting plate 201 and the connecting plate are adjusted at an angle through rotational connection. The screw rod 203 and the pin 204 are combined to fix the connecting plate to the external lifting equipment, achieving rapid lifting. The support plate and fixing component 206 on the inner wall of the platform 1 provide internal support and fixation. Inside the fixing component 206, the fixing frame 2061 and the fixing plate 2062 form a basic frame. The spring plate 2063 cooperates with the fixing groove 2064 to elastically clamp and fix the cargo. The clamping processing 3 at the bottom of the lifting mechanism 2 is connected to the lifting plate 206. The vehicle is connected and secured, enabling the spreader and crane to work together to complete the cargo lifting task and meet the lifting requirements. The use of the new platform spreader ensures operational safety by maintaining a balanced center of gravity to prevent slippage, thereby improving the stability and safety of the equipment lifting. At the same time, the sufficient loading space of the spreader can increase the loading capacity at one time and reduce the number of loading and unloading operations, thereby improving operational efficiency. For example, the loading and unloading time of a single excavator is reduced from 30 minutes to 20 minutes, an efficiency increase of 30%. In addition, the platform spreader is adaptable to a variety of goods, reducing swaying and collisions during loading and unloading, reducing the risk of damage, and ensuring the quality of cargo transportation.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The clamping processing 3 includes a connecting frame 301, which is fixedly connected to the bottom of the outer wall of the fixed frame 2061. Support frame 1 302 is fixedly connected to the four corners of the top of the outer wall of the connecting frame 301. A movable frame 303 is slidably connected to the middle of the inner wall of the connecting frame 301. A pulley 304 is rotatably connected to the four corners of the bottom of the movable frame 303. A drive assembly 305 is fixedly connected to the front and rear sides of the inner wall of the connecting frame 301. The drive assembly 305 includes a fixed rod 3051, which is fixedly connected to the front and rear sides of the inner wall of the connecting frame 301. A hydraulic push rod 3052 is rotatably connected to one end of the outer wall of the fixed rod 3051. A flap 3053 is rotatably connected to the output end of the hydraulic push rod 3052. The flap 3053 is rotatably connected to the middle of the inner wall of the connecting frame 301. Support frame 2 3054 is fixedly connected to one side of the top of the flap 3053.

[0034] Specifically, after the hydraulic push rod 3052 is activated, its telescopic movement drives the flap 3053 to rotate around the fulcrum. The fixed rod 3051 provides support. The rotation of the flap 3053 drives the second support frame 3054, which in turn pushes the connected components. The movable frame 303 slides within the connecting frame 301. Together with the fixed structure of the first support frame 302 and the connecting frame 301, a stable frame is formed. The linear motion of the hydraulic push rod 3052 is converted into the rotational motion of the flap 3053, realizing the clamping, positioning or processing of objects. The support structure at the four corners ensures uniform force and stable operation.

[0035] Reference Figure 1 , Figure 2 and Figure 3 Anti-slip strips 4 are fixedly connected to the outer walls of the hanging platform 1. Fixed frames 5 are fixedly connected to the bottom left and right sides of the hanging platform 1. Multiple springs 7 are fixedly connected to the middle of the inner wall of the hanging platform 1. Support plate 6 is fixedly connected to the top of the outer wall of the multiple springs 7. Multiple connecting plates 9 are fixedly connected to one side of the outer wall of the connecting frame 301. Connecting column 8 is fixedly connected to the top of the outer wall of the connecting plate 9. Positioning plate 10 is fixedly connected to the middle of the inner wall of the moving frame 303. Multiple fixing holes 11 are opened on the top of the outer wall of the positioning plate 10.

[0036] Specifically, the anti-slip strips 4 around the outer wall enhance grip and prevent slippage; the fixed frames 5 on the left and right sides of the bottom are used to connect to the external structure for positioning and fixing; the spring 7 in the middle of the inner wall cooperates with the support plate 6, and through the elastic buffering mechanism, it can play a shock-absorbing role for objects placed on the support plate 6 during hoisting; the connecting frame 301 is connected to the connecting column 8 through the connecting plate 9, which can realize the assembly connection with other components; the positioning plate 10 in the moving frame 303 cooperates with the external components through the fixing hole 11, which can realize the position limitation of the moving frame 303 or the fixed connection with other components. The whole achieves stable support and positioning functions during hoisting through the mechanical connection and elastic buffering of each component.

[0037] Working Principle: When the port equipment cargo lifting platform is in operation, the lifting plate 201 and connecting plate 202 in the lifting mechanism 2 around the platform 1 are flexibly adjusted by rotation. The connecting plate 202 is fixed to the external lifting equipment by a combination of screw rod 203 and pin 204, achieving rapid lifting. The support plate 205 and fixing component 206 on the inner wall of the platform 1 provide internal support and fixation. In the fixing component 206, the fixing frame 2061 and fixing plate 2062 form a basic frame. The spring plate 2063 cooperates with the fixing groove 2064 to elastically clamp and fix the cargo placed on the platform 1. The clamping mechanism 3 at the bottom of the lifting mechanism 2 is connected and fixed to the crane through its structural design, enabling the lifting equipment and the crane to work together to complete the port cargo lifting task and meet the equipment requirements. For lifting requirements of various types of goods, based on the overall platform dimensions of 9.3m × 3.9m, it is welded using Q345B steel plates, balancing strength and lightweight. It features 30-degree ramps at the front and rear, and 5cm × 1cm steel anti-slip strips along the travel path. There are 12 lifting points on both sides of the platform, with a single lifting point load of 8.75 tons, and the balance can be flexibly adjusted. Four additional lifting points are added at the four corners, with a single lifting point load of 13.75 tons, capable of lifting equipment up to 55 tons. The walking area is reinforced for anti-slip, and a buffer device is installed at the bucket position. The front slider and rear brake achieve precise positioning, and the concealed rear wheel brake prevents slippage. There are sling securing points on both sides, and adjustable steel plates and plastic steel blocks at the front and rear assist in positioning. Tool boxes are installed on both sides of the platform, and the bottom is designed for drainage. The ramp is appropriately extended for a gentler slope, and the shock-absorbing platform base is recessed with a height ≤100mm to ensure the passage of construction machinery.

[0038] When the hydraulic push rod 3052 is activated, the extension and retraction of its output end will drive the flap 3053, which is rotatably connected to it, to rotate around the fulcrum in the middle of the inner wall of the connecting frame 301. The fixed rod 3051 provides stable support for the hydraulic push rod 3052. As the flap 3053 rotates, the second support frame 3054 on its top side will move synchronously, pushing or pulling the connected parts. The movable frame 303 slides in the middle of the inner wall of the connecting frame 301 through the bottom pulley 304, and can be adjusted in position under the drive of the flap 3053. With the fixed connection structure between the first support frame 302 and the connecting frame 301, a stable support frame is formed. The linear motion of the hydraulic push rod 3052 is converted into the rotational motion of the flap 3053, thereby realizing the clamping, positioning or processing operation of the object. The support structure at the four corners ensures uniform force and stability of the operation.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
