Description

Technical Field

[0001] This utility model belongs to the technical field of intelligent manufacturing, specifically relating to a combined steel plate lifting device. Background Technology

[0002] In many industrial sectors, such as construction, machinery manufacturing, and shipbuilding, steel plates are frequently required to be lifted and moved. Due to their large size, surface area, and varying degrees of regularity in shape, the lifting process of steel plates presents numerous challenges.

[0003] In existing technologies, adsorption is often used for lifting large steel plates. This method typically utilizes the principle of vacuum adsorption, employing multiple adsorption plates on the lifting device that are tightly attached to the surface of the steel plate, relying on the negative pressure adsorption force to lift the plate. However, this adsorption-based lifting method has significant drawbacks: Firstly, the adsorption process requires maintaining a continuous vacuum environment, which consumes a large amount of energy to drive the vacuum pump and other related equipment, resulting in high energy consumption for the entire lifting operation. Secondly, adsorption-based lifting poses safety risks. If the adsorption plates fail to seal properly, the vacuum system malfunctions, or external factors interfere during the lifting process (such as sudden pressure changes or collisions causing the adsorption plates to shift), the steel plate can easily detach, leading to serious safety accidents and posing a significant safety threat to on-site personnel and surrounding equipment.

[0004] Another common method is mechanical gripping hoisting, which uses a gripper structure to grab the steel plate for hoisting. However, this method also has the following problems in practical applications: for steel plates placed close to the ground, there is almost no gap between them and the ground for the grippers to insert. Even if the grippers are adapted to the size and shape of the steel plate, it is difficult to successfully grab the steel plate. This greatly reduces the practicality of mechanical gripping hoisting in such situations.

[0005] In summary, existing steel plate hoisting methods, whether adsorption-based or mechanical clamping-based, each have their own insurmountable drawbacks and cannot meet the actual needs of industrial production for safe, efficient, and stable steel plate hoisting. Utility Model Content

[0006] To address the technical problems existing in the background art, this utility model provides a combined steel plate lifting device.

[0007] This utility model is achieved through the following technical solution: a combined steel plate lifting device, including a lifting device carrier; and further comprising: Several adsorption mechanisms are arranged at the bottom of the lifting device carrier; At least one set of clamping mechanisms is installed at the edge of the lifting carrier; the adsorption mechanism picks up the steel plate and moves it away from the bearing surface by a predetermined distance; the clamping mechanism switches to the clamping mode as needed and acts on the edge of the steel plate.

[0008] In a further embodiment, the interior of the lifting carrier has a degree of freedom of extension and retraction, that is, the position of the clamping mechanism is relatively adjustable.

[0009] In a further embodiment, the adsorption mechanism has a contact protection function.

[0010] In a further embodiment, when the gripping mechanism is in gripping mode, the adsorption mechanism switches from suction mode to auxiliary mode as needed.

[0011] In a further embodiment, during the dynamic process of the adsorption mechanism picking up the steel plate, the clamping mechanism is in a space avoidance mode.

[0012] In a further embodiment, the lifting device carrier includes: The main body is used to arrange the aforementioned adsorption mechanisms; At least two sets of carriers are installed around the main body via telescopic components; the carriers are configured to mount the clamping mechanism.

[0013] In a further embodiment, the adsorption mechanism includes: The contact body is rigidly connected to the lifting device carrier; An adsorbent is flexibly mounted on the contact body; an overprotective contact structure is formed between the contact body and the adsorbent; the overprotective contact structure is used to control the orientation of the lifting carrier.

[0014] In a further embodiment, the auxiliary mode is to select a predetermined number of adsorption mechanisms to be in an adsorption state as needed.

[0015] The beneficial effects of this utility model are as follows: This utility model combines an adsorption mechanism and a clamping mechanism to form an adsorption and clamping combined hoisting solution: For steel plates that are attached to the bearing surface, the adsorption mechanism first picks them up and lifts them off the bearing surface to a predetermined height, solving the problem of mechanical clamping without insertion gaps; subsequently, the clamping mechanism can be switched to the clamping mode to act on the edge of the steel plate according to the weight, size and hoisting stability requirements of the steel plate, making up for the defects of high dependence on vacuum system and insufficient safety of single adsorption method, realizing the full process adaptation from "ground picking" to "stable hoisting".

[0016] During the dynamic process of the adsorption mechanism picking up the steel plate, the clamping mechanism automatically enters the space avoidance mode to prevent interference between the two from causing scratches on the steel plate or damage to the mechanism. When the clamping mechanism starts the clamping mode, the adsorption mechanism can switch to the auxiliary mode as needed (keeping part of the adsorption mechanism working), forming a dual fixation of "clamping as the main function and adsorption as the auxiliary function", which greatly reduces the risk of the steel plate falling off.

[0017] On the other hand, the adsorption mechanism is equipped with sensors and contact protection functions. The sensors obtain the position parameters of the steel plate in real time and control the direction of the lifting device in reverse. At the same time, the combination structure of the flexible adsorption body and the contact body can buffer the contact impact force between the lifting device and the steel plate, avoid rigid collisions that may cause deformation of the steel plate or adsorption failure, and further improve the safety of lifting.

[0018] Compared to traditional single vacuum adsorption hoisting, which requires a high-energy-consuming vacuum environment to be maintained continuously, this invention allows the adsorption mechanism to switch to auxiliary mode (reducing the number of working adsorption mechanisms) or stop working after the clamping mechanism is activated. Stable hoisting can be achieved solely through mechanical clamping, significantly reducing the energy consumption of the vacuum system. At the same time, the modular structure eliminates the need for manual intervention to switch hoisting modes. The coordinated actions of adsorption, avoidance, and clamping can be automatically completed through sensors and control logic, simplifying the operation process, reducing manual adjustment time, and improving the overall efficiency of steel plate hoisting. It is especially suitable for continuous hoisting operations in large-scale steel plate processing workshops. Attached Figure Description

Detailed Implementation

[0024] The present invention will now be further described with reference to the accompanying drawings and embodiments.

[0025] Example 1 A combined steel plate 5 lifting device includes a lifting device carrier. It also includes several adsorption mechanisms 3 arranged at the bottom of the lifting device carrier. The number of adsorption mechanisms 3 in this embodiment can be determined according to the actual area of ​​the steel plate 5; for example, a larger area requires a greater number of adsorption mechanisms 3.

[0026] However, the adsorption mechanism 3 has limited load-bearing capacity and a low safety factor. Therefore, in this embodiment, at least one set of clamping mechanisms 4 is configured at the edge of the lifting carrier, preferably an even number of clamping mechanisms 4. It is worth mentioning that the clamping mechanisms 4 in this embodiment are located at the edge; otherwise, it would be difficult to meet the clamping requirements of the steel plate 5 in this embodiment.

[0027] Furthermore, the adsorption mechanism 3 picks up the steel plate 5 and moves it away from the bearing surface at a predetermined height, while the clamping mechanism 4 switches to the clamping mode and acts on the edge of the steel plate 5.

[0028] By adopting the above scheme, the adsorption mechanism 3 first lifts the steel plate 5, making room for the clamping mechanism 4 to insert, thus avoiding the phenomenon of the clamps getting stuck. After clamping, mechanical force is used to fix it, compensating for the risk of easy detachment by relying solely on adsorption. At the same time, the clamping action on the edge can limit the shaking and deformation of the steel plate 5, which is especially suitable for large-sized or thin steel plates 5.

[0029] Meanwhile, in order to adapt to steel plates 5 of different sizes, the lifting carrier disclosed in this embodiment has a degree of freedom of extension and retraction, that is, the position of the clamping mechanism 4 is adjustable. Figure 1 As shown, the lifting device carrier includes a main body 1 and a support body 2 installed around the main body 1 via a telescopic component, exemplified by a telescopic cylinder. Under the action of the telescopic cylinder, the support body 2 moves closer to or further away from the main body 1, meaning the position of the clamping mechanism 4 is relatively adjustable. In other embodiments, the telescopic component can be other mechanical structures, which will not be elaborated upon. It should be noted that... Figure 1 The telescopic component given is only for one direction; in other embodiments, it can be set in two different directions.

[0030] Based on this, in this embodiment, the adsorption mechanism 3 is partially or entirely installed on the main body 1, while the clamping mechanism 4 is correspondingly configured on the support body 2. Under the action of the telescopic cylinder: when the telescopic cylinder is in a compressed state, the clamping mechanism 4 and the adsorption mechanism 3 move closer to each other, which is suitable for clamping smaller area steel plates 5, such as... Figure 1 As shown; conversely, when the telescopic cylinder is in the lifting state, the clamping mechanism 4 and the adsorption mechanism 3 are far apart, which is suitable for clamping larger area steel plates 5.

[0031] Based on the above description, the adsorption mechanism 3 and the clamping mechanism 4 in this embodiment have the following working modes: when the clamping mechanism 4 is in the clamping mode (i.e., the clamping mechanism 4 acts on the steel plate 5), the adsorption mechanism 3 switches from the absorption mode to the auxiliary mode as needed, that is, the adsorption mechanism 3 can be fully, partially or not in the adsorption state.

[0032] For example, suppose a large steel plate 5 needs to be gripped. During the gripping process, as the gripping mechanism 4 extends to grip the steel plate 5, the adsorption mechanism 3 is initially in suction mode, with multiple adsorption heads adsorbing the steel plate 5 to assist in fixing its position. However, once the gripping mechanism 4 has firmly gripped the steel plate 5, the adsorption mechanism 3 can switch to auxiliary mode according to actual needs. For example, only half of the adsorption heads remain in the adsorption state, while the other half stops adsorbing, using the force of the gripping mechanism 4 to firmly fix the steel plate 5. This achieves a situation where the adsorption mechanism 3 is partially in the adsorption state.

[0033] Considering that the initial action on the steel plate 5 is by the adsorption mechanism 3, and the clamping mechanism 4 is the subsequent action, the clamping mechanism 4 is in a space avoidance mode during the dynamic process of the adsorption mechanism 3 picking up the steel plate 5. In other words, throughout the entire process of the lifting device moving down towards the steel plate 5 and adsorbing it, it should be ensured that the adsorption mechanism 3 acts on the steel plate 5 first, followed by the clamping mechanism 4. (Refer to...) Figure 2 The state diagram is shown in the image.

[0034] Therefore, the clamping mechanism 4 described in this embodiment is a mechanical triggering structure and a pneumatic triggering structure. The mechanical triggering structure is the structural design in patent CN202410008354.4. It is in an avoidance state before the adsorption mechanism 3 completes adsorption, and begins to act on the steel plate 5 after adsorption is completed.

[0035] In another embodiment, when the clamping mechanism 4 is a pneumatically triggered structure, one set of pneumatically triggered structures is taken as an example. Figure 3 As shown, the system includes: a push cylinder 301, the connecting end of which is hinged to a designated position on the carrier 2, and a clamping plate 302 hinged to the output end. The clamping plate 302 is also rotatably mounted at the edge of the carrier 2. In use, before the adsorption mechanism 3 acts on the steel plate 5, the push cylinder 301 is in an extended state, and the clamping plate 302 is tilted under the action of the push cylinder 301, with the lowest surface of the clamping plate 302 higher than the lowest surface of the adsorption mechanism 3. Until the adsorption mechanism 3 acts on the steel plate 5 and moves upward as a whole, the push cylinder 301 switches to a retracted state, and the clamping plate 302 rotates in the direction of the steel plate 5 until it acts on the steel plate 5.

[0036] Example 2 Based on the combined steel plate 5 lifting device disclosed in Embodiment 1, this embodiment also discloses the specific structure of the adsorption mechanism 3, which has a contact protection function.

[0037] like Figure 4 As shown, it includes a contact body 401 rigidly connected to the lifting carrier. Referring to the description in Embodiment 1, if the adsorption mechanism 3 is only distributed within the main body 1, it is connected to the main body 1; if it is partially disposed on the carrier 2, it is partially connected to the carrier 2.

[0038] Furthermore, an adsorption element, such as a suction nozzle 402, is flexibly mounted on the contact body 401. The flexible mounting structure described in this embodiment is as follows: Figure 4 As shown, it includes: guide posts 403, fixed on the contact body 401. Each set of guide posts 403 is fitted with a compression spring 404, and the bottom of the compression spring 404 is provided with a mounting plate 405, which is used to mount the suction nozzle 402. The mounting plate can reciprocate on the guide posts 403, and a displacement sensor, such as L1001-6 (compact type) or L3001-50.8, is mounted on the mounting plate 405.

[0039] When the suction body (nozzle 402) contacts the steel plate 5, the mounting plate moves upward along the guide post 403 under the reaction force of the steel plate 5, and the compression spring 404 is compressed. At this time, the displacement sensor can detect the displacement change of the mounting plate in real time. The principle is that the elastic characteristics of the compression spring 404 provide a buffered movement space for the mounting plate (and the suction nozzle 402), realizing flexible contact between the suction nozzle 402 and the steel plate 5. The displacement sensor monitors the contact state and position change of the suction nozzle 402 and the steel plate 5 in real time based on the displacement feedback of the mounting plate.

[0040] On the one hand, the flexible installation structure can effectively buffer the impact force when the suction nozzle 402 contacts the steel plate 5, avoiding damage to the suction nozzle 402 and the steel plate 5 due to rigid collision. At the same time, it can also adapt to certain unevenness on the surface of the steel plate 5, ensuring good contact between the suction nozzle 402 and the steel plate 5. On the other hand, the displacement sensor can accurately capture the displacement of the mounting plate, so that the operator or control system can understand the working status of the suction nozzle 402 in a timely manner, such as whether it is in normal contact with the steel plate 5 and whether the contact pressure is appropriate, providing a basis for precise control of the hoisting process.

[0041] This structure solves many problems. It solves the problem of rigid impact when the lifting device adsorption mechanism 3 comes into contact with the steel plate 5, protecting the adsorption components and the steel plate 5, and improving the service life and safety of the lifting device. It also solves the problem of difficulty in real-time and accurate monitoring of the contact state between the adsorption mechanism 3 and the steel plate 5, which greatly enhances the reliability and controllability of adsorption during the lifting process and can effectively avoid dangerous situations such as the steel plate 5 falling due to poor adsorption.
