These materials include but are not limited to scrap steel, pig iron, ore, garbage, scrap metal, industrial waste, gravel, construction waste and domestic waste; the design of the lotus gripper enables it to handle loose or block materials. Its working principle is to use a fixed hinge seat, hydraulic cylinder, hydraulic gripper, hydraulic oil pipe and matching hydraulic integrated control circuit, and use a control handle to control the opening and closing movement of the hydraulic grabber to achieve the gripping and loading of various materials.

[0003] There is a gap between adjacent petals of the lotus gripper in the prior art when they are closed, causing the hydraulic grab to drop along the gap between adjacent petals when grabbing bulk materials, which not only reduces the volume of the material grabbed, but also creates a safety hazard.

[0004] Therefore, it is necessary to provide a lotus clamp to solve the above-mentioned technical problems. Utility Model Content

[0022] like Figure 1 As shown, a lotus gripper comprises a base 1, on the outer wall of the base 1 are arranged a plurality of hydraulic grippers 2 for gripping materials, the outer wall of the base 1 is hinged with a plurality of hydraulic cylinders 3 corresponding in number to the hydraulic grippers 2, the movable ends of the hydraulic cylinders 3 are hinged to the hydraulic grippers 2, and the end of the hydraulic grippers 2 close to the base 1 is hinged to the base 1.

[0023] In specific operation, the opening and closing movement of the hydraulic gripper 2 is controlled by an external control handle. When it is necessary to grab materials, the control handle causes the hydraulic cylinder 3 to push the petals of the hydraulic gripper 2 to close, thereby clamping the materials. When the petals of the hydraulic gripper 2 are closed, the end of the hydraulic gripper 2 away from the base 1 is completely closed, which can prevent the materials from falling from the bottom; when it is necessary to put down the materials, the control handle causes the hydraulic cylinder 3 to retract, the petals of the hydraulic gripper 2 are opened, and the materials are released;

[0024] The hydraulic gripper 2 can be used flexibly in various application scenarios, especially in situations where efficient and safe material handling is required, such as loading and unloading operations in railways, ports, wood production, engineering construction and other departments.

[0025] like Figures 1 to 4 As shown, a lotus gripper is provided with a metal mesh 4 for intercepting materials between two adjacent hydraulic grippers 2, and the size of the metal mesh 4 is equal to the spacing between two adjacent hydraulic grippers 2 when they are fully expanded; fixing parts are evenly distributed along the outer edge of the metal mesh 4, and connecting parts are evenly embedded on the inner wall of each hydraulic gripper 2, and the fixing parts are connected to the connecting parts by pressing the fixing parts to fix the metal mesh 4.

[0026] The fixing part includes a positioning block 5, which is fixedly installed on the metal mesh 4 and is hollow. A guide rod 6 is movably connected inside the positioning block 5, a slider 8 is fixedly connected to the outer side of the guide rod 6, a threaded rod 7 is fixedly connected to the side of the guide rod 6 close to the slider 8, and a disc is rotatably connected to the side of the guide rod 6 away from the threaded rod 7, and the diameter of the disc is larger than the diameter of the guide rod 6.

[0027] The connecting piece includes a fixing nut 10, which is embedded and installed on the inner wall of the hydraulic gripper 2. One end of the fixing nut 10 is set to be an opening, and a slide groove 9 is opened inside the fixing nut 10. One end of the slider 8 is set in the slide groove 9 and slides with it; the slide groove 9 is divided into two sections, one section is set as a straight groove and the other section is set as a threaded groove, and the straight groove is close to the opening of the fixing nut 10.

[0028] An internal thread groove is provided at a position near the thread groove inside the fixing nut 10 , and an external thread groove is provided on the outer side of the threaded rod 7 , and the internal thread groove meshes with the external thread groove.

[0029] The external thread groove does not contact the sliding groove 9.

[0030] An internal thread groove is provided at a position near the thread groove inside the fixing nut 10 , and an external thread groove is provided on the outer side of the threaded rod 7 , and the internal thread groove meshes with the external thread groove.

[0031] During specific operation, when grabbing materials, the control handle makes the hydraulic cylinder 3 push the petals of the hydraulic gripper 2 to close. At this time, the gap between the two adjacent hydraulic grippers 2 can be intercepted by the metal mesh 4, which can prevent the finely crushed materials from falling along the gap between the two adjacent metal meshes 4 when grabbing finely crushed materials, thereby increasing the volume of single material grabbing and reducing the risk of falling materials and injuring pedestrians. At the same time, the metal mesh 4 has a mesh design. Even if the grabbed materials contain moisture, the metal mesh 4 with a mesh design can drain the excess moisture in the materials in time, reducing the weight of the grip;

[0032] At the same time, the mesh size of the metal mesh 4 can be changed according to the shape and size of the material to be grabbed in the water. The hydraulic cylinder 3 is retracted by controlling the handle, and the petals of the hydraulic gripper 2 are opened. At this time, the metal mesh 4 can be directly pulled to move in the direction away from the hydraulic gripper 2, and the metal mesh 4 drives the guide rod 6 to move, and the movement of the guide rod 6 drives the slider 8 to slide along the thread groove. Since the pitch of the thread groove is equal to the pitch of the internal thread groove, the slider 8 can drive the threaded rod 7 to rotate when sliding along the thread groove until the threaded rod 7 is completely rotated out of the internal thread groove. At this time, the slider 8 just moves to the straight groove position, and the rear slider 8 slides out of the opening of the fixing nut 10 along the straight groove, and the metal mesh 4 can be quickly removed;

[0033] When installing the metal mesh 4, the same method can be adopted. First, align the slider 8 with the straight groove position, slide the slider 8 into the straight groove, manually press the disc to move in the direction of the fixing nut 10, and the movement of the disc drives the guide rod 6 to move, and the movement of the guide rod 6 drives the threaded rod 7 to move synchronously until the slider 8 moves to the thread groove position, and the threaded rod 7 can rotate until the threaded rod 7 is screwed into the fixing nut 10, so that the internal thread groove and the external thread groove are meshed with each other to fix the metal mesh 4. After the metal mesh 4 is fixed, as the volume of the material grabbed by the hydraulic gripper 2 increases, the material will press against the disc position. The larger the volume of the material, the tighter it presses, so as to prevent the metal mesh 4 from falling off.

[0034] By setting the fixing parts and the connecting parts, not only can the metal mesh 4 be fixed and disassembled quickly, but also as the volume of the material increases, the material presses the fixing parts tighter, thereby preventing the metal mesh 4 from falling off.
