Description

Technical Field

[0001] This utility model relates to the field of transmission equipment technology, specifically to a gantry crane device and a feeding device. Background Technology

[0002] BOOM bags are widely used in the production industry, often for the transfer, storage, and packaging of materials. Materials are transported to the unloading station under the protection of the BOOM bags.

[0003] In related technologies, when using ton bags for material feeding, a gantry crane is typically used to move the ton bags above the hopper. At this point, workers open the bottom of the ton bag, allowing material to flow into the hopper from the opened bottom. However, as the material in the ton bag gradually decreases, the bag loses its filling material, causing it to deform. This can lead to the bottom of the ton bag falling towards the hopper, potentially touching the hopper's feeding port and affecting the feeding of remaining material. Therefore, workers must constantly monitor and control the gantry crane's lifting to prevent the bottom of the ton bag from touching the hopper's feeding port. Furthermore, when bridging occurs in the ton bag, the flow of material becomes obstructed. In this case, workers also need to continuously control the gantry crane's raising and lowering to resolve the bridging, which can easily damage the gantry crane. Utility Model Content

[0004] In view of this, the present invention provides a gantry crane device and a feeding device to solve the problem that the operator needs to control the gantry crane device at any time, so as to avoid the bottom of the ton bag touching the feeding port of the silo and the bridging phenomenon of the material in the ton bag, which would easily damage the gantry crane device.

[0005] In a first aspect, this utility model provides a gantry crane device, comprising:

[0006] A frame, said frame being adapted to be installed on the ground;

[0007] A drive structure is disposed on the side of the frame away from the ground;

[0008] A gantry crane structure includes a gantry crane assembly and a transfer assembly. The gantry crane assembly is slidably mounted on the drive structure. One end of the transfer assembly is connected to the gantry crane assembly, and the other end is adapted to be connected to a ton bag.

[0009] The adapter assembly is configured to be elastic, and is adapted to deform under external force to elongate or contract.

[0010] Beneficial effects: By using a flexible transfer component to lift ton bags, the transfer component moves the ton bag directly above the hopper for feeding. The ton bag's own weight causes the transfer component to extend to its maximum extension position, allowing feeding. As the material in the ton bag decreases, its weight decreases, reducing the force exerted by the ton bag on the transfer component. This causes the transfer component to gradually contract under its own elasticity, maintaining a consistent distance between the ton bag and the hopper. This prevents the ton bag from contacting the hopper's feeding port and affecting the feeding of remaining material. This avoids repeated lifting and lowering of the gantry crane, extending its service life and improving the feeding efficiency of the ton bag.

[0011] In one alternative embodiment, under the weight of the ton bag, the adapter assembly is in an elongated state; under the gradually decreasing weight of the ton bag, the adapter assembly is in a gradually contracted state.

[0012] Beneficial effects: By setting the adapter component to have extended and retracted states, and because the adapter component is configured to be elastic, after the end of the adapter component is connected to the ton bag, the adapter component will extend under the weight of the ton bag. When moving the ton bag through the adapter component, in order to avoid the ton bag shaking due to the elasticity of the adapter component during the movement, the ton bag can only be moved in the extended state. In addition, since the material in the ton bag needs to be fed, the weight of the ton bag will gradually decrease during the feeding process, thereby reducing the force of the ton bag on the adapter component. As a result, the adapter component will gradually retract under its own elasticity and remain in the retracted state, so that the ton bag and the hopper can always maintain a certain distance.

[0013] In one alternative embodiment, under the action of an external force, the adapter assembly also has a jittering state that switches back and forth between the extended state and the retracted state.

[0014] Beneficial effects: By setting the adapter component to also have a shaking state, under the continuous action of external force, the adapter component is configured to be elastic, which allows it to have an elongated state and a contracted state. Under the intermittent action of external force, the adapter component needs to neutralize the external force applied to it through its own elasticity, so that the adapter component will switch back and forth between the elongated state and the contracted state and be in a shaking state. At this time, the adapter component will drive the ton bag to shake synchronously, so that the material in the ton bag will not cause bridging during the feeding process, which is conducive to further improving the feeding efficiency of the material and can avoid repeated operation of the gantry crane to raise and lower to shake the ton bag.

[0015] In one alternative embodiment, the adapter assembly includes an adapter and a hook, one end of the adapter being connected to the overhead crane assembly and the other end being connected to the hook, the hook being adapted to connect to the ton bag; the adapter is configured to be resilient.

[0016] Beneficial effects: By setting the adapter assembly including an adapter and a hook, which in this embodiment are a spring and a hook, respectively, one end of the adapter is connected to the overhead crane assembly, and the other end is connected to the hook to install the hook on the overhead crane assembly. The hook can then be connected to the ton bag, so that the ton bag can be connected to the overhead crane assembly through the hook and adapter. When the overhead crane assembly slides relative to the drive structure, the overhead crane assembly can drive the ton bag to move synchronously, so as to move the ton bag directly above the hopper. In addition, the adapter is configured to be elastic.

[0017] In one alternative embodiment, the hook has a hook portion adapted to be connected to the ton bag via the hook portion.

[0018] Beneficial effects: By providing a hook part, which is a hook groove in this embodiment, when the hook part is connected to the ton bag, the connecting part of the ton bag can extend into the hook part, thereby realizing the connection between the hook part and the ton bag. At the same time, the connection between the hook part and the ton bag through the hook part helps to improve the connection stability between the hook part and the ton bag.

[0019] In one alternative embodiment, the adapter assembly further includes at least two snap-fit ​​members, one of which is disposed between the adapter assembly and the overhead crane assembly, and the other of which is disposed between the adapter assembly and the hook assembly.

[0020] Beneficial effects: By setting the adapter component, two snap-fit ​​components are also included. In this embodiment, the snap-fit ​​components are buckles. One snap-fit ​​component is set between the adapter component and the overhead crane component, thereby connecting and fixing the end of the adapter component and the overhead crane component together. The other snap-fit ​​component is set between the adapter component and the hook component, thereby connecting and fixing the end of the adapter component and the hook component together.

[0021] In one optional embodiment, the overhead crane assembly includes a retractor and a connector. The retractor is slidably disposed on the drive structure. One end of the connector is connected to the retractor, and the other end is connected to the end of the adapter via a snap-fit ​​connector.

[0022] Beneficial effects: By setting the overhead crane assembly to include a winding component and a connector, in this embodiment the winding component and the connector are respectively a winding machine and a chain. The winding component is slidably mounted on the drive structure. One end of the connector is connected to the winding component, and the other end is connected to the end of the adapter through a snap-fit ​​component, so that the winding component can move the ton bag to directly above the hopper through the connector and the adapter assembly.

[0023] In one alternative embodiment, the winding member has a winding state for winding the connector and an unwinding state for unwinding the connector.

[0024] Beneficial effects: By setting the retractor to have both a retracting and unretracting state, when the retractor is connected to the ton bag via the connector and adapter, the retractor can retract the connector in the retracting state to prevent the ton bag from contacting the hopper when the retractor moves the ton bag directly above the hopper. When the retractor moves the ton bag directly above the hopper, the retractor can unretract the connector in the unretracting state to lower the ton bag to the vicinity of the hopper's feeding port, thus preventing material leakage during feeding operations.

[0025] In one alternative embodiment, the drive structure includes a guide rail and a drive member. The guide rail is disposed on the side of the frame away from the ground, the drive member is slidably disposed on the guide rail, and the winding member is connected to the drive member.

[0026] Beneficial effects: By setting the drive structure including a guide rail and a drive component, the drive component in this embodiment is an electric hoist. The guide rail is set on the side of the frame away from the ground, and the drive component is slidably set on the guide rail. At the same time, the winding component is connected to the drive component, so that the drive component can drive the winding component to slide relative to the guide rail, thereby enabling the winding component to move the ton bag to directly above the hopper through the connector and the adapter assembly.

[0027] Secondly, this utility model also provides a feeding device, including the above-mentioned overhead crane device.

[0028] Beneficial effects: It can avoid repeated operation of raising or lowering the gantry crane, which helps to extend the service life of the gantry crane and improve the efficiency of material delivery in ton bags. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] The following is combined Figure 1 The following describes embodiments of the present invention.

[0036] According to embodiments of the present invention, in one aspect, a gantry crane device is provided, such as... Figure 1 As shown, the device includes a frame, a drive structure 2, and a gantry crane structure 3. The frame is adapted to be installed on the ground. The drive structure 2 is located on the side of the frame away from the ground. The gantry crane structure 3 includes a gantry crane assembly 31 and a transfer assembly 32. The gantry crane assembly 31 is slidably mounted on the drive structure 2. One end of the transfer assembly 32 is connected to the gantry crane assembly 31, and the other end is adapted to be connected to the ton bag 1. The transfer assembly 32 is configured to be elastic and is adapted to deform under external force to elongate or contract.

[0037] The above-described overhead crane device comprises a drive structure 2 mounted on a frame and an overhead crane structure 3 mounted on the drive structure 2. The frame can be mounted on the ground, while the drive structure 2 is mounted on the side of the frame away from the ground. The overhead crane structure 3 includes an overhead crane assembly 31 and a connecting assembly 32. The overhead crane assembly 31 is slidably mounted on the drive structure 2. One end of the connecting assembly 32 is connected to the overhead crane assembly 31, and the other end is connected to the ton bag 1. Under the action of external force, the overhead crane assembly 31 can slide relative to the drive structure 2 and drive the ton bag 1 to move synchronously through the connecting assembly 32. This allows the ton bag 1 to be moved directly above the hopper for easy feeding.

[0038] Furthermore, the adapter 32 is configured to be elastic, so that it can deform and extend or contract under the action of external force. Thus, when the overhead crane assembly 31 moves the ton bag 1 through the adapter 32, the adapter 32 will extend under the gravity of the ton bag 1. When the adapter 32 extends to its limit, the ton bag 1 will be fixed at the extension limit position of the adapter 32 and moved by the adapter 32 until the ton bag 1 is moved directly above the hopper. When the ton bag 1 is removed from the end of the adapter 32, the adapter 32 will lose the action of external force and contract under its own elasticity.

[0039] Therefore, by using a flexible transfer component 32 to lift the ton bag 1, when the transfer component 32 moves the ton bag 1 directly above the hopper for feeding, the ton bag 1 will extend the transfer component 32 to its maximum extension position due to its own weight. At this point, the ton bag 1 can be fed. As the material in the ton bag 1 decreases, the weight of the ton bag 1 will decrease, reducing the force exerted by the ton bag 1 on the transfer component 32. As a result, the transfer component 32 will gradually contract under its own elasticity, thus maintaining a distance between the ton bag 1 and the hopper at all times. This prevents the ton bag 1 from contacting the hopper's feeding port and affecting the feeding of the remaining material. In this way, repeated lifting or lowering of the gantry crane can be avoided, which helps extend the service life of the gantry crane and improves the feeding efficiency of the ton bag 1.

[0040] In one embodiment, such as Figure 1 As shown, under the gravity of the ton bag 1, the adapter 32 is in an elongated state; under the gradually decreasing gravity of the ton bag 1, the adapter 32 is in a gradually contracted state.

[0041] The overhead crane device described above features a transfer component 32 that has both extended and retracted states. Because the transfer component 32 is configured to be elastic, after its end is connected to the ton bag 1, the transfer component 32 extends under the weight of the ton bag 1. When moving the ton bag 1 via the transfer component 32, to prevent the ton bag 1 from shaking due to the elasticity of the transfer component 32 during movement, the transfer component 32 must be in its extended state before the ton bag 1 can be moved. Furthermore, since the material in the ton bag 1 needs to be fed, the weight of the ton bag 1 gradually decreases during the feeding process, thus reducing the force exerted by the ton bag 1 on the transfer component 32. Consequently, the transfer component 32 gradually retracts under its own elasticity and remains in a retracted state, ensuring that the ton bag 1 maintains a constant distance from the hopper.

[0042] In one embodiment, such as Figure 1 As shown, under the action of external force, the adapter 32 also has a shaking state that switches back and forth between the extended state and the retracted state.

[0043] The overhead crane device described above also has a shaking state by setting the adapter component 32. Under the continuous action of external force, since the adapter component 32 is configured to be elastic, the adapter component 32 can have an extended state and a contracted state. Under the intermittent action of external force, the adapter component 32 needs to neutralize the external force applied to it through its own elasticity, so that the adapter component 32 will switch back and forth between the extended state and the contracted state and be in a shaking state. At this time, the adapter component 32 will drive the ton bag 1 to shake synchronously, so that the material in the ton bag 1 will not cause bridging during the feeding process, which is conducive to further improving the feeding efficiency of the material and can avoid repeated operation of the overhead crane device to shake the ton bag 1.

[0044] In one embodiment, such as Figure 1 As shown, the adapter assembly 32 includes an adapter 321 and a hook 322. One end of the adapter 321 is connected to the overhead crane assembly 31, and the other end is connected to the hook 322. The hook 322 is adapted to be connected to the ton bag 1. The adapter 321 is configured to be flexible.

[0045] The overhead crane device described above includes a connecting component 32 comprising a connecting element 321 and a hook 322. In this embodiment, the connecting element 321 is a spring and the hook 322 are a hook, respectively. One end of the connecting element 321 is connected to the overhead crane assembly 31, and the other end is connected to the hook 322 connector 312 to mount the hook 322 onto the overhead crane assembly 31. The hook 322 can then be connected to the ton bag 1, allowing the ton bag 1 to be connected to the overhead crane assembly 31 via the hook 322 and the connecting element 321. As the overhead crane assembly 31 slides relative to the driving structure 2, it can move the ton bag 1 synchronously to move it directly above the hopper. Furthermore, the connecting element 321 is configured to be elastic.

[0046] In one embodiment, such as Figure 1 As shown, the hook 322 has a hook portion, and the hook 322 is adapted to be connected to the ton bag 1 via the hook portion.

[0047] The overhead crane device described above has a hook part 322, which is a hook groove in this embodiment. When the hook part 322 is connected to the ton bag 1, the connection part of the ton bag 1 can extend into the hook part, thereby realizing the connection between the hook part 322 and the ton bag 1. At the same time, the connection between the hook part 322 and the ton bag 1 through the hook part helps to improve the connection stability between the hook part 322 and the ton bag 1.

[0048] In one embodiment, such as Figure 1 As shown, the adapter assembly 32 also includes at least two snap-fit ​​members 323, one of which is disposed between the adapter assembly 321 and the overhead crane assembly 31, and the other snap-fit ​​member 323 is disposed between the adapter assembly 321 and the hook member 322.

[0049] The overhead crane device with the above structure also includes two snap-fit ​​parts 323 by setting the adapter component 32. In this embodiment, the snap-fit ​​parts 323 are buckles. One snap-fit ​​part 323 is disposed between the adapter component 321 and the overhead crane component 31, thereby connecting and fixing the end of the adapter component 321 and the overhead crane component 31 together. The other snap-fit ​​part 323 is disposed between the adapter component 321 and the hook component 322, thereby connecting and fixing the end of the adapter component 321 and the hook component 322 together.

[0050] In one embodiment, such as Figure 1 As shown, the overhead crane assembly 31 includes a winding member 311 and a connector 312. The winding member 311 is slidably mounted on the drive structure 2. One end of the connector 312 is connected to the winding member 311, and the other end is connected to the end of the adapter 321 via a snap-fit ​​member 323.

[0051] The overhead crane device described above includes a crane assembly 31 comprising a winding member 311 and a connecting member 312. In this embodiment, the winding member 311 and the connecting member 312 are a winding machine and a chain, respectively. The winding member 311 is slidably mounted on the drive structure 2. One end of the connecting member 312 is connected to the winding member 311, and the other end is connected to the end of the adapter 321 via a snap-fit ​​member 323, so that the winding member 311 can move the ton bag 1 directly above the hopper via the connecting member 312 and the adapter assembly 32.

[0052] In one embodiment, such as Figure 1 As shown, the winding member 311 has a winding state of winding connector 312 and a winding state of unwinding connector 312.

[0053] The overhead crane device described above is equipped with a winding member 311 that has both winding and unwinding states. When the winding member 311 is connected to the ton bag 1 via the connector 312 and the adapter 32, the winding member 311 can wind up the connector 312 in the winding state to prevent the ton bag 1 from contacting the silo when the winding member 311 moves the ton bag 1 directly above the silo. When the winding member 311 moves the ton bag 1 directly above the silo, the winding member 311 can unwind the connector 312 in the unwinding state to lower the ton bag 1 to the vicinity of the silo's feeding port via the connector 312, thus preventing material leakage from the ton bag 1 during feeding operations.

[0054] In one embodiment, such as Figure 1 As shown, the drive structure 2 includes a guide rail and a drive component. The guide rail is located on the side of the frame away from the ground, and the drive component is slidably mounted on the guide rail. The winding component 311 is connected to the drive component.

[0055] The above-described overhead crane device includes a drive structure 2 comprising a guide rail and a drive component. In this embodiment, the drive component is an electric hoist. The guide rail is located on the side of the frame away from the ground, and the drive component is slidably mounted on the guide rail. Meanwhile, the winding component 311 is connected to the drive component, thereby enabling the drive component to drive the winding component 311 to slide relative to the guide rail. This allows the winding component 311 to move the ton bag 1 directly above the hopper via the connector 312 and the adapter 32.

[0056] According to an embodiment of the present invention, another aspect also provides a feeding device, such as... Figure 1 As shown, the above-mentioned overhead crane device is included. The feeding device with the above structure, by including the overhead crane device, uses a flexible transfer component 32 to lift the ton bag 1. When the transfer component 32 moves the ton bag 1 directly above the hopper for feeding, the ton bag 1 will extend to its maximum extension position due to its own weight. At this point, the ton bag 1 can be fed. As the material in the ton bag 1 decreases, the weight of the ton bag 1 decreases, reducing the force exerted by the ton bag 1 on the transfer component 32. This causes the transfer component 32 to gradually contract under its own elasticity, thus maintaining a distance between the ton bag 1 and the hopper, preventing the ton bag 1 from contacting the hopper's feeding port and affecting the feeding of remaining material. This avoids repeated raising or lowering of the overhead crane device, extending its service life and improving the feeding efficiency of the ton bag 1.

[0057] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
