Description

Technical Field

[0001] This utility model relates to the field of ton bag hoisting and lifting technology, and more specifically, to a ton bag lifting device. Background Technology

[0002] A ton bag, also known as a bulk container, is a type of packaging bag or container used for holding and transporting large quantities of bulk materials. Because of its large capacity, it is usually measured in tons, hence the name "ton bag."

[0003] Currently, the ton bags are equipped with zippers at the top and lifting straps at the four corners that work with the hooks of the lifting equipment. The main purpose of the zippers is to facilitate the loading, unloading, and sealing of materials, while ensuring the safety of materials during transportation. After the materials are loaded into the ton bag, the zippers are closed. When it is necessary to lift the ton bag, the four lifting straps on the ton bag can be hooked onto the hooks of the lifting equipment in sequence. The lifting equipment will then move the ton bag to the unloading area. Finally, the discharge port at the bottom of the ton bag can be opened to carry out the unloading process.

[0004] During the hoisting and lifting of the ton bag using the above method, the ton bag will be stretched as the material flows out. At this time, the ton bag cannot be effectively unfolded, and the probability of local material accumulation will greatly increase. The material unloading effect is not smooth, and the hoisting and lifting process of the ton bag needs to be improved. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background art and to propose a ton bag lifting device.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A ton bag lifting device includes a lifting hook connected to an overhead crane, a fixing plate, a lifting ring, a hook, and an auxiliary vibration assembly.

[0008] The lifting ring is located at the center of the top surface of the fixed plate, which is rectangular in shape, and is connected to the lifting hook.

[0009] The four hooks are respectively set on the four corners of the bottom surface of the fixed plate and are respectively matched with the four lifting straps of the ton bag so that the top of the ton bag is fully unfolded and the lifting straps are in a vertically taut state during the lifting process.

[0010] Furthermore, the fixed plate is provided with an auxiliary vibration assembly.

[0011] Furthermore, the auxiliary vibration assembly includes a telescopic component, a contact plate, and a vibration motor. The telescopic component is provided on the fixed plate, the telescopic component is connected to the contact plate, and the vibration motor is provided on the contact plate.

[0012] The above solution can reduce the labor intensity of subsequent manual intervention in clearing the blockage by using auxiliary vibration components.

[0013] Furthermore, the contact plate is provided with a mounting plate, a guide roller is slidably fitted inside the mounting plate, a spring is sleeved on the outside of the guide roller, one end of the spring is connected to the mounting plate, and the other end of the spring is connected to a pressure detection element electrically connected to the telescopic component. A limit block is provided at the end of the guide roller away from the pressure detection element.

[0014] The above solution uses a pressure sensor to immediately stop the telescopic component after the contact plate contacts the upper surface of the ton bag. At this time, the contact plate is accurately positioned, and the subsequent vibration motor can assist in unblocking the material.

[0015] Furthermore, the pressure detection element is a pressure sensor.

[0016] Furthermore, both the lifting hook and the hook are designed to prevent detachment.

[0017] Furthermore, both the hook and the lifting ring are welded to the fixing plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] Compared to existing technologies, this device uses a fixed plate, lifting rings, and four hooks to lift the ton bag with four lifting straps. This design allows the top four corners of the ton bag to be fully extended during the lifting process, and the lifting straps to be in a vertically taut state. As a result, the probability of local material accumulation during subsequent unloading is greatly reduced, and the unloading process is smoother. The lifting process of the ton bag is improved and the effect is better. Attached Figure Description

[0025] 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:

[0026] like Figures 1 to 3 As shown, a ton bag lifting device includes a lifting hook 1 connected to an overhead crane, a fixing plate 2, a lifting ring 3, a hook 4, and an auxiliary vibration assembly.

[0027] The lifting ring 3 is set at the center of the top surface of the fixed plate 2, which has a rectangular main body shape, and is connected to the lifting hook 1;

[0028] Four hooks 4 are respectively set on the four corners of the bottom surface of the fixed plate 2 and are respectively matched with the four lifting straps of the ton bag so that the top of the ton bag is fully unfolded and the lifting straps are in a vertically taut state during the lifting process (specifically, the hooks 4 and the lifting rings 3 are welded to the fixed plate 2).

[0029] Further refinements of the embodiments of this utility model, such as... Figure 1 As shown, an auxiliary vibration assembly is provided on the fixed plate 2. The auxiliary vibration assembly includes a telescopic component 5, a contact plate 6, and a vibration motor 7. The telescopic component 5 is provided on the fixed plate 2, and the contact plate 6 is connected to the telescopic component 5. The vibration motor 7 is provided on the contact plate 6.

[0030] Further optimizations of the above-described embodiments, such as... Figure 2 and Figure 3 As shown, a mounting plate 8 is provided on the contact plate 6, and a guide roller 9 is slidably fitted inside the mounting plate 8. A spring 10 is sleeved on the outside of the guide roller 9. One end of the spring 10 is connected to the mounting plate 8, and the other end of the spring 10 is connected to a pressure detection element 11 (the pressure detection element 11 is specifically a pressure sensor) that is electrically connected to the telescopic member 5. A limit block is provided at the end of the guide roller 9 away from the pressure detection element 11. The limit block is not labeled in the figure.

[0031] Further refinements of the embodiments of this utility model, such as... Figure 1 As shown, both the lifting hook 1 and the hook 4 are equipped with anti-detachment hooks.

[0032] It should be noted that the overhead crane, telescopic component 5, vibration motor 7, and pressure sensor are all electrically connected to the controller, which is not shown in the figure.

[0033] The working process of this utility model:

[0034] When preparing to lift the ton bag, hook the four slings onto the four hooks 4 one after another. Then, the overhead crane drives the lifting hook 1 to move upward, thus moving the ton bag away from the ground. At this time, the ton bag will be stretched and the four slings will be in a vertically taut state. Then, the four corners of the ton bag can be unfolded from above. After the ton bag is moved horizontally to the unloading area, the opening at the bottom of the ton bag can be opened manually to start the unloading process. Since the ton bag is in an unfolded state, the probability of material being stored inside during the unloading process is greatly reduced.

[0035] Based on this, the controller controls the movement of the telescopic component 5, which in turn drives the contact plate 6 to approach the upper surface of the ton bag. When the pressure sensor contacts the upper surface of the ton bag, it can immediately detect the change in pressure value (the pressure value is 0 when not in contact with the ton bag) and send a feedback signal to the controller. The controller then controls the telescopic component 5 to stop immediately (the pressure sensor also stops after the telescopic component stops). The pressure sensor can buffer during the contact process. Then the controller controls the vibration motor 7 to work, which can assist in unloading, reduce the labor intensity of subsequent manual intervention, improve the ease of operation, and thus optimize the hoisting and lifting process of the ton bag. It should be noted that the pressure detection component and the contact plate are at the same height when the ton bag is not initially in contact.

[0036] Compared to existing technologies, this device uses a fixed plate 2, lifting ring 3, and four hooks 4 to lift the ton bag with four lifting straps. This design allows the top four corners of the ton bag to be fully extended and the lifting straps to be in a vertically taut state during the lifting process, which greatly reduces the probability of local material accumulation during subsequent unloading.

[0037] Based on this, the labor intensity of subsequent manual intervention in clearing can be reduced by using auxiliary vibration components. The contact plate 6 equipped with vibration motor 7 can accurately contact the surface of the ton bag, thus optimizing the hoisting and lifting process of the ton bag and improving its effectiveness.

[0038] 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.
