Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel slag storage tank hoisting and transfer technology, and more specifically, to a safe hoisting and transfer device for steel slag storage tanks. Background Technology
[0002] Steel slag is a byproduct of the steelmaking process. It consists of various oxides formed by the oxidation of impurities such as silicon, manganese, phosphorus, and sulfur in pig iron during the smelting process, as well as salts formed by the reaction of these oxides with the solvent.
[0003] Steel slag is typically stored in tanks with lids to prevent environmental pollution and safety hazards caused by open-air storage. Both the tanks and lids are made of metal. When the steel slag inside the tank needs to be processed, the entire tank must be hoisted and transported to the designated processing area. The existing hoisting process involves setting up several hoisting positions along the circumference of the tank opening at the top. Then, several wire ropes connected to the overhead crane hooks are sequentially connected to these hoisting positions before subsequent transport can begin. During this process, operators need to climb to a height and circle around the tank opening to complete multiple connections, which poses significant safety hazards during the installation and connection process. Utility Model Content
[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a safe hoisting and transfer device for steel slag storage tanks.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A safe lifting and transfer device for steel slag storage tanks includes a lifting plate and a steel slag storage tank. The lifting plate is equipped with lifting lugs for connecting to a crane hook. The steel slag storage tank includes a cover. The lifting plate is also equipped with a mounting frame. An installation groove is formed at the center of the inner side of the mounting frame, and an infrared transmitter is installed in the installation groove. An infrared receiver electrically connected to the infrared transmitter is set at the center of the upper surface of the cover. An electromagnetic plate is also provided on the inner side of the mounting frame, which is in contact with the surface of the cover. The electromagnetic plate has a through hole that allows infrared signals to pass through. The size of the through hole is larger than that of the infrared receiver. The mounting frame is also equipped with a clamping assembly to improve the safety of the steel slag storage tank during lifting and transfer.
[0007] This device eliminates the need for operators to climb to heights and make multiple connections between steel wire ropes and the hoisting position by circumferentially circumferentially around the opening of the steel slag storage tank. It only requires the use of detection elements to first automatically locate the mounting frame, and then to complete the electromagnetic adsorption of the cover and the stable clamping of the tank surface before proceeding with the subsequent hoisting and transportation process, significantly improving safety.
[0008] Furthermore, the clamping assembly includes a hydraulic cylinder and a semi-circular arc plate. The hydraulic cylinders are symmetrically arranged on the mounting frame, and the hydraulic cylinders are connected to the semi-circular arc plates. The two semi-circular arc plates form a ring, and the inner diameter of the ring is consistent with the diameter of the steel slag storage tank.
[0009] Furthermore, the mounting frame is symmetrically provided with telescopic rods that connect the two semi-circular arc plates respectively.
[0010] The above solution, through the clamping components, can further improve the safety and stability of the steel slag storage tank during subsequent hoisting and transportation, based on the electromagnetic adsorption of the cover. The telescopic rod can extend the service life of the hydraulic cylinder.
[0011] Furthermore, an electromagnet is embedded in the inner wall of the semi-circular plate.
[0012] After the clamping components complete the double clamping and fixing of the steel slag storage tank, the controller immediately energizes the electromagnet, which further improves the safety of the steel slag storage tank during subsequent hoisting and transportation, resulting in better safety.
[0013] Furthermore, a distance sensor is provided on the mounting bracket.
[0014] The above solution uses a distance sensor to measure the distance between the mounting frame and the ground, thus accurately lowering the mounting frame to complete the electromagnetic adsorption of the top cover of the steel slag storage tank, making the lifting and lowering control of the mounting frame more accurate.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] Compared to existing technologies, this device eliminates the need for operators to climb to heights and make multiple connections between steel wire ropes and the hoisting position by circumferentially circumferentially around the opening of the steel slag storage tank. Instead, it only requires the use of detection elements to first automatically position the mounting frame, and then to complete the electromagnetic adsorption of the cover and the stable clamping of the tank surface before proceeding with the subsequent hoisting and transfer process, significantly improving safety.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:
[0022] like Figure 1 and Figure 2 As shown, a safe hoisting and transfer device for steel slag storage tanks includes a hoisting plate 1 and a steel slag storage tank 2 placed on the ground of the storage area. The hoisting plate 1 is provided with a lifting lug 11 for connecting to a crane hook. The crane is not shown in the figure. The steel slag storage tank 2 includes an arc-shaped cover. The hoisting plate 1 is also provided with a mounting frame 12. An mounting groove 14 is opened at the center of the inner side of the mounting frame 12. An infrared transmitter 15 is installed in the mounting groove 14. An infrared receiver 21 electrically connected to the infrared transmitter 15 is provided at the center of the upper surface of the cover. An electromagnetic plate 13 is also provided on the inner side of the mounting frame 12, which is in contact with the surface of the cover. The electromagnetic plate 13 has a through hole 131 that allows infrared signals to pass through. The size of the through hole 131 is larger than that of the infrared receiver 21. The mounting frame 12 is also provided with a clamping assembly to improve the safety of the steel slag storage tank 2 during hoisting and transfer.
[0023] Specifically, the clamping assembly includes a hydraulic cylinder 31 and a semi-circular arc plate 33. The mounting frame 12 is symmetrically equipped with synchronously moving hydraulic cylinders 31. The hydraulic cylinders 31 are connected to the semi-circular arc plates 33. The two semi-circular arc plates 33 form a ring. The inner diameter of the ring is the same as the diameter of the steel slag storage tank 2 (that is, the semi-circular arc plates 33 are in close contact with the surface of the steel slag storage tank 2). In further optimization, the mounting frame 12 is symmetrically equipped with two telescopic rods 32 that connect the two semi-circular arc plates 33 respectively to extend the service life of the hydraulic cylinders 31.
[0024] It should be noted that the overhead crane, infrared transmitter 15, infrared receiver 21, electromagnetic plate 13, and hydraulic cylinder 31 are all electrically connected to the controller, which is not shown in the figure.
[0025] The working process of this utility model:
[0026] First, the overhead crane drives the device to the area above the cover of the slag storage tank 2. Then, the position of the mounting frame 12 is adjusted. When the infrared signal emitted by the infrared transmitter 15 passes through the through hole 131 and can be accurately received by the infrared receiver 21 on the cover, the infrared receiver 21 will then send a signal back to the controller. The device will then stop moving horizontally. The overhead crane then drives the mounting frame 12 to descend. When the electromagnetic plate 13 is in contact with the cover, the controller controls the electromagnetic plate 13 to be energized, which will achieve the adsorption of the top of the slag storage tank 2. Then, the controller controls the clamping component to work, which will complete the clamping and fixing of the surface of the slag storage tank 2. After the above two fixings are completed, the overhead crane can lift the slag storage tank 2 and transfer it to the designated processing area for subsequent slag unloading and processing.
[0027] Compared to existing technologies, this device does not require operators to climb to a height and complete multiple connections between steel wire ropes and the hoisting position by circumferentially circumferentially around the opening of the steel slag storage tank 2. It only requires the use of detection elements to first complete the automatic positioning of the mounting frame 12, and then complete the electromagnetic adsorption of the cover and the stable clamping of the tank surface before starting the subsequent hoisting and transportation process, which significantly improves safety.
[0028] In some embodiments, an electromagnet is embedded in the inner wall of the semi-circular plate 33. The electromagnet is electrically connected to the controller and is not shown in the figure. In this embodiment, after the clamping assembly completes the double clamping and fixing of the steel slag storage tank 2, the controller controls the electromagnet to be energized, which can further improve the safety of the steel slag storage tank 2 during subsequent hoisting and transportation.
[0029] In other embodiments, a distance sensor is provided on the mounting frame 12, which is not shown in the figure; the function of this embodiment is to use the distance sensor to measure the distance between the mounting frame 12 and the ground, so that the mounting frame 12 can be lowered accurately to complete the electromagnetic adsorption of the top cover of the steel slag storage tank 2, and the lifting control of the mounting frame 12 is more accurate.
[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
