Description

Technical Field

[0001] This utility model relates to the field of leak-proof cover technology, and in particular to a leak-proof cover. Background Technology

[0002] In industries such as cement plants, waste clothing is shredded and turned into alternative fuel, which is then transported to cement plants and other locations to replace coal for incineration. This reduces waste and carbon emissions, and also achieves the goals of environmental protection and lower production costs. After the alternative fuel is shredded, it is grabbed by a crane grab bucket and transferred to a transport vehicle. However, during the grabbing process, because the alternative fuel is in a shredded state, it leaks out from the gaps in the grab bucket, which not only wastes the alternative fuel but also pollutes the environment, increases cleanup costs, and poses safety hazards.

[0003] Therefore, based on the above situation, it is necessary to design a leak-proof cover to solve the above problems. Utility Model Content

[0004] This invention provides a leak-proof cover to solve the problems in the prior art.

[0005] The technical problem solved by this utility model is achieved by the following technical solution:

[0006] A leak-proof cover includes a wrapping component that can be installed around the outside of a crane grab bucket. The wrapping component includes multiple fitting parts that are detachably connected to the crane grab bucket and a flexible part connecting two adjacent fitting parts. The fitting parts are configured one-to-one with the grab clamps on the crane grab bucket. When the crane grab bucket is in a closed state, the wrapping component wraps around the outside of the crane grab bucket to prevent material leakage. When the crane grab bucket is in an extended state, the bottom of the wrapping component unfolds to unload the material inside the crane grab bucket.

[0007] Preferably, the bonding portion includes a soft portion and a hard portion disposed at the bottom of the soft portion.

[0008] Preferably, the inner wall of the fitting part is provided with a fixing member for engaging and fixing with the grab clamp on the crane grab bucket.

[0009] Preferably, the flexible part has an accordion pleat structure and is made of a multi-layered composite flexible material.

[0010] Preferably, the upper end of the package is provided with a flexible sleeve, and a pull rope for auxiliary fixation of the upper end of the package is movably inserted through the flexible sleeve.

[0011] Preferably, the side wall of the package has an opening for unfolding the package from the side, and the opening is provided with a connector.

[0012] The beneficial effects of this utility model are as follows: by surrounding the outside of the crane grab bucket and connecting and fixing the fitting part to the grab clamp on the crane grab bucket, when the crane grab bucket is unfolded to grab the material, the bottom opening of the package unfolds with the crane grab bucket and gradually penetrates into the material. When the crane grab bucket is closed, the material is confined inside the crane grab bucket and the package, preventing the material from leaking out of the gaps in the crane grab bucket, reducing dust, reducing environmental pollution and material waste.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0021] Reference Figures 1-5As shown, a leak-proof cover includes a wrapping component that can be wrapped around the outside of a crane grab bucket 3 during use. To accommodate the use of the crane grab bucket 3, the wrapping component includes multiple fitting parts 2 and flexible parts 1 connecting adjacent fitting parts 2. The fitting parts 2 are correspondingly arranged with the grab clamps on the crane grab bucket 3. For flexible use, the fitting parts 2 are detachably connected to the crane grab bucket 3. When not in use, the wrapping component can be removed for maintenance or replacement. During use, when the crane grab bucket 3 grabs materials... The crane grab bucket 3 unfolds first, and the flexible part 1 adaptively adjusts to the unfolding size of the crane grab bucket 3, making the bottom opening of the package larger. As the crane grab bucket 3 descends and penetrates into the material, it gradually grabs the material. At this time, the crane grab bucket 3 closes. After closing, the crane grab bucket 3 causes the bottom opening of the package to shrink. When transferring to the transport vehicle, the limiting effect of the crane grab bucket 3 on the material and the wrapping effect of the package can prevent the material from leaking from the gaps in the crane grab bucket 3, reducing environmental pollution and material waste.

[0022] Reference Figures 1-5 As shown, further, in order to improve the service life of the package, the bonding part 2 includes a soft part 21 and a hard part 22 located at the bottom of the soft part 21. The soft part 21 can be made of fiber materials, composite materials, etc., and the hard part 22 can be made of metal alloys, composite materials, etc. In the process of producing alternative fuels, some materials will accumulate on the ground. When the package is wrapped on the crane grab bucket 3, the hard part 22 is located at the grab end of the crane grab bucket 3. When it grabs the material on the ground, the hard part 22 will contact the ground and bear the impact and friction of the ground, which can reduce the wear of the bonding part 2 and improve the service life of the package.

[0023] Reference Figures 1-5 As shown, furthermore, in order to fix it to the crane grab bucket 3, the inner wall of the fitting part 2 is provided with a fixing member 4 for engaging and fixing with the grab bucket on the crane. The fixing member 4 can be two oppositely arranged long strip structures with grooves, and is adapted to the crane grab bucket 3. The fixing member 4 can be made of rubber, silicone or other materials. In use, the fitting part 2 is aligned with the grab clamp on the crane grab bucket 3, and then the fixing member 4 is bent to increase the opening of the fixing member 4. Then the grab clamp is locked in the groove of the fixing member 4, and under its own elastic force, it can tightly "hold" the grab clamp, forming a dynamic fastening effect. Even if the grab bucket moves frequently or is subjected to force and vibration, the fixing member 4 can maintain the locking state through elastic buffering. In actual use, the fixing member 4 can fully wrap the grab clamp, improve the fixing effect, and reduce the amount of material entering between the fitting part 2 and the grab clamp.

[0024] Reference Figures 1-5As shown, furthermore, in order to better match the opening and closing action of the crane grab bucket 3, the flexible part 1 is an accordion pleat structure and a multi-layer composite flexible material. The accordion pleats can be tightly compressed and fitted when the grab bucket is closed, completely wrapping the outer contour of the grab bucket. When the grab bucket is unfolded to unload, the pleats gradually open and the bottom unfolds, covering the movement trajectory of the grab bucket without dead corners, better matching the opening and closing action of the grab bucket and reducing the occurrence of material leakage. The outer layer of the multi-layer composite flexible material can be made of high-strength fiber cloth (such as aramid, polyester) or rubber-coated cloth, the middle layer can be made of sponge, foamed silicone or elastic fiber layer, and the inner layer can be made of polytetrafluoroethylene (PTFE), polyethylene (PE) or food-grade rubber, etc., to ensure strength while maintaining overall flexibility.

[0025] Reference Figures 1-5 As shown, furthermore, in order to improve the stability of the package, a flexible sleeve 5 is provided at the upper end of the package. A pull rope 6 for auxiliary fixation of the upper end of the package is movably passed through the flexible sleeve 5. When in use, the flexible sleeve 5 is pre-fitted onto the top of the grab bucket (such as the grab bucket arm or crossbeam). After the pull rope 6 passes through the flexible sleeve 5, it is tightened manually or mechanically. The ring pull force tightly fits the upper end of the package to the surface of the grab bucket to form an initial positioning. This is especially suitable for scenarios where there is an irregular curved surface at the top of the grab bucket. It fills the gaps that the fixing part 4 of the fitting part 2 cannot cover, forming "double fixation from top to bottom", and improving the stability of the package when the grab bucket vibrates or the material is impacted.

[0026] Reference Figures 1-5 As shown, furthermore, to improve the convenience of using the package, an opening is provided on the side wall of the package for unfolding the package from the side. A connector 7 is provided on the opening. The connector 7 can be a Velcro, snap fastener, or other structure. When in use, the package can be unfolded and then attached to the outer wall of the grab bucket, and then fixed by the connector 7. After use, the package can be unfolded to easily remove it from the grab bucket. At the same time, the opening design allows the package to be adapted to the outer wall of grab buckets of different sizes or shapes. Flexible installation can be achieved by adjusting the fixing position of the connector 7, which enhances the versatility of the package and reduces compatibility problems caused by differences in grab bucket models.
