Technical Field
[0001] This utility model relates to the field of aerial work platform technology, specifically an adjustable telescopic unloading platform. Background Technology
[0002] In high-altitude operations such as high-rise building construction and equipment installation, telescopic unloading platforms are a key piece of equipment used to receive materials hoisted by tower cranes and other lifting equipment, and safely transfer them into the building. Traditional unloading platforms typically use telescopic tracks to adjust their distance from the building structure to adapt to different operational needs, and their core function is to provide a temporary aerial working surface for material turnover.
[0003] However, existing telescopic unloading platforms pose significant safety hazards in practical applications. When a tower crane lifts goods onto the platform, the goods are often unstable due to factors such as high-altitude winds and swaying slings, making it difficult to land accurately and smoothly in the platform's center area. Existing platforms generally lack effective auxiliary positioning and centering stabilization mechanisms, relying primarily on manual guidance by construction workers using traction ropes, which is not only inefficient but also poses significant safety risks. Swaying goods are highly susceptible to impacting the platform's side walls or railings, potentially damaging the goods themselves and causing vibrations in the platform structure. In severe cases, this can even lead to material overturning or platform instability, posing a serious safety threat to operators and the area below.
[0004] Therefore, this utility model proposes an adjustable telescopic unloading platform. Utility Model Content
[0005] The purpose of this utility model is to provide an adjustable telescopic unloading platform to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: An adjustable telescopic unloading platform includes a support frame, a sliding table for loading goods is provided on the side of the support frame, the sliding table includes two vertically distributed side plates, a horizontal plate is provided on the side of the side plates, and a carrier plate is provided at the bottom of the side plates; a push plate is provided on one side of each of the two side plates, the top of the push plate is inclined, and a positioning unit is provided inside the side plate to push the two push plates close to each other at the same time, so that the goods are pushed to the center area of the carrier plate by the positioning unit.
[0006] Preferably, the positioning unit includes a sliding column located on the side of the push plate. The outer wall of the sliding column is provided with a fixed cylinder and is slidably connected to it. The fixed cylinder passes through the side plate and is fixedly connected to it. An air pump is provided above the support frame. There are two fixed cylinders, both of which are connected to the air outlet of the air pump. When the air pump supplies air to the outside, the sliding column in the fixed cylinder is simultaneously displaced.
[0007] Preferably, the carrier plate has two slides inside, which are slidably connected to the carrier plate, and a buffer pad is provided above the slides.
[0008] Preferably, the slide has a rotating plate inside, which is rotatably connected to the slide via a rotating shaft. The carrier plate has a slider inside and is slidably connected to it. The rotating plate has a groove that matches the outer edge of the slider. When the rotating plate rotates to a 75-degree angle with the carrier plate, the outer wall of the slider that slides out from inside the carrier plate contacts the groove.
[0009] Preferably, the side plate has a connecting plate inside, and the connecting rod is rotatably connected to the side plate through a rotating shaft. The connecting plate has a first insert rod inside, which passes through the connecting plate and the side plate. Its end has a fixing block, and the side of the fixing block has a second insert rod. The side of the connecting plate has a limiting plate and is fixedly connected to it. The limiting plate has a through hole for the second insert rod to be inserted. When the connecting plate rotates to the point where the limiting plate contacts the side plate, the second insert rod is inserted into the through hole.
[0010] Preferably, the two side plates are rotatably connected to the carrier plate via a pivot, and the two horizontal plates are rotatably connected to the side plates via a pivot.
[0011] This utility model has at least the following beneficial effects: In this invention, by setting a positioning unit, when the air pump is supplying air to the outside, the sliding column inside the fixed cylinder simultaneously displaces, thereby pushing the two push plates closer together and moving the goods to the center area of the carrier plate. This solves the problem of existing telescopic unloading platforms lacking effective auxiliary positioning and centering stabilization mechanisms, making it difficult for goods to land accurately and smoothly in the center area of the platform. It avoids safety risks such as goods shaking and hitting the platform side walls or guardrails, causing damage to the goods, platform structural vibration, material overturning, or platform instability, thus improving the safety and efficiency of the unloading process. Furthermore, if the goods are cylindrical, the connecting plate inside the side plate can be rotated until the limiting plate contacts the side plate. At this point, the second insert rod is inserted into the through hole of the limiting plate, causing the connecting plate to tilt downwards relative to the side plate and fix its position. This, in conjunction with the raised rotating plate, allows for stable positioning of cylindrical goods, improving the applicability of the unloading platform. Attached Figure Description

Detailed Implementation
[0014] 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.
[0015] Please see Figure 1-5 This utility model provides a technical solution: an adjustable telescopic unloading platform, including a support frame 1. The support frame 1 is used to fix the rear end of the overall unloading platform to maintain the stability of cargo transportation. The side of the support frame 1 is provided with a sliding table for loading cargo. The sliding table is slidably connected to the support frame 1. The sliding table includes two vertically distributed side plates 2. The side plates 2 are provided with a horizontal plate 3 on their sides. The bottom of the side plates 2 is provided with a carrier plate 4. The two side plates 2 are rotatably connected to the carrier plate 4 through a pivot. The two horizontal plates 3 are rotatably connected to the side plates 2 through a pivot. When the unloading platform needs to be transported, the horizontal plate 3 and the side plate 2, and the side plate 2 and the carrier plate 4 can be folded to reduce the space occupied by the unloading platform and facilitate transportation and storage.
[0016] Each of the two side plates 2 is equipped with a push plate 5. The top of the push plate 5 is slanted. Inside the side plate 2, there is a positioning unit that pushes the two push plates 5 together. The positioning unit pushes the goods to the center area of the carrier plate 4. When the goods are placed in the carrier plate 4, the bottom of the goods will abut against the slanted area of the push plate 5. Then, guided by the slant angle, the goods will slowly enter between the two push plates 5, which facilitates the subsequent positioning and correction of the goods. The positioning unit includes a sliding column 6 located on the side of the push plate 5. The end of the sliding column 6 is fixedly connected to the push plate 5. The outer wall of the sliding column 6 is provided with a fixed cylinder 7 and is slidably connected to it. The fixed cylinder 7 passes through the side plate 2 and is fixedly connected to it. An air pump 8 is provided above the support frame 1 and is fixedly connected to it. There are two fixed cylinders 7, both of which are connected to the air outlet of the air pump 8. When the air pump 8 is supplying air to the outside, the sliding columns 6 in the fixed cylinder 7 are simultaneously displaced, thereby driving the push plate 5 to move closer to each other. Conversely, when the air pump 8 is sucking air, the two sliding columns 6 will move away from each other under the action of negative pressure.
[0017] Furthermore, the carrier plate 4 is equipped with two slide blocks 9 inside, which are slidably connected to the carrier plate 4. A buffer pad 10 is provided above the slide block 9 and fixedly connected to it. The buffer pad 10 can effectively reduce the impact force on the carrier plate 4 when the goods fall, protect the structure of the carrier plate 4 from damage, and reduce the risk of the goods being damaged due to impact. At the same time, the buffer pad 10 can also separate the goods from the platform by a small distance, making it easier for the slide block 9 to slide the goods, which is more conducive to the pushing of the positioning unit.
[0018] The slide 9 has a rotating plate 11 inside, and a portion of the buffer pad 10 is also located on the surface of the rotating plate 11 and fixedly connected to it. The rotating plate 11 is rotatably connected to the slide 9 via a rotating shaft. The carrier plate 4 has a slider 12 inside and is slidably connected to it. The rotating plate 11 has a groove 13 that matches the outer edge of the slider 12. When the rotating plate 11 rotates to a 75-degree angle with the carrier plate 4, the outer wall of the slider 12, which slides out from inside the carrier plate 4, contacts the groove 13. In this state, the pressure of the goods above the slide 9 on the rotating plate 11 will not cause the slider 12 to slide into the carrier plate 4. At the same time, because the positioning unit pushes the goods with a small amplitude, the rotating plate 11 will not completely detach from the surface of the slider 12 during the process of pushing the slide 9.
[0019] The side plate 2 has a connecting plate 14 inside. The connecting rod is rotatably connected to the side plate 2 via a pivot. The connecting plate 14 has a first insertion rod 15 inside. The first insertion rod 15 passes through the connecting plate 14 and the side plate 2 and can slide freely inside both. Its end has a fixing block 16 and is fixedly connected to it. The side of the fixing block 16 has a second insertion rod 17 and is fixedly connected to it. The side of the connecting plate 14 has a limiting plate 18 and is fixedly connected to it. The limiting plate 18 has a through hole 19 inside for the second insertion rod 17 to be inserted. When the connecting plate 14 rotates to the point where the limiting plate 18 contacts the side plate 2, the second insertion rod 17 is inserted into the through hole 19. In this state, the connecting plate 14 is tilted downward relative to the side plate 2, and the positions of both are fixed. In conjunction with the raised rotating plate 11, the cylindrical goods can be stably positioned in the carrier plate 4, improving the applicability of this equipment.
[0020] Working principle: When using this telescopic unloading platform, the platform is first secured to a suitable high-altitude working position using the support frame 1 to ensure its stability. The tower crane lifts the goods onto the platform; due to high-altitude winds and swaying slings, the goods are initially unstable. Gradually, the bottom of the goods comes into contact with the inclined area of the push plates 5, slowly moving between the two push plates 5 under the guidance of the inclined angle. At this point, the air pump 8 above the support frame 1 is activated, supplying air to the fixed cylinder 7. The sliding columns 6 inside the fixed cylinder 7 simultaneously displace under air pressure, causing the push plates 5 to move closer together. As the push plates 5 move, the goods are pushed to the center area of the carrier plate 4, achieving precise positioning. Simultaneously, the pushing plates 5's resistance to the goods ensures their stability.
[0021] If the cargo is cylindrical, the connecting plate 14 inside the side plate 2 can be rotated until the limiting plate 18 contacts the side plate 2. At this time, the second insertion rod 17 is inserted into the through hole 19 of the limiting plate 18, so that the connecting plate 14 is tilted downward relative to the side plate 2 and its position is fixed. Then, the rotating plate 11 is lifted upward, and the bottom of the rotating plate 11 is blocked by the slider 12 to keep it in the raised state. The downward tilting connecting plate 14 and the raised rotating plate 11 cooperate with each other to stably position the cylindrical cargo, improving the applicability of the unloading platform. During the entire unloading process, the unloading platform effectively solves the problem that the cargo is difficult to land accurately and smoothly in the center area of the platform in traditional unloading platforms through the coordinated action of the positioning unit, the slide 9, the rotating plate 11 and the connecting plate 14, thereby improving the safety and efficiency of unloading.
