Description

Technical Field

[0001] This utility model relates to the field of plate and frame processing technology, and in particular to a plate and frame lifting device for a plate and frame filter press. Background Technology

[0002] Plate and frame filters are the core components of plate and frame filter presses, and their structural design and materials directly affect the equipment's filtration efficiency, service life, and applicable range. During the use of a plate and frame filter press, replacing the plates and frames requires lifting and lowering them. Since each plate and frame is quite heavy, lifting equipment is needed to lift and disassemble them.

[0003] In the existing technology, lifting equipment mainly includes a crane and a spreader. When in use, the crane hooks the spreader, and the spreader hooks the plate frame. However, the existing spreader structure is relatively simple and its stability is not good after installation. The spreader is prone to shaking during movement, which in turn causes the plate frame to shake, making it inconvenient to use.

[0004] Therefore, we propose a plate and frame hanger for a plate and frame filter press. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the simple structure of the lifting device, poor stability after installation, easy shaking of the lifting device during movement, which leads to shaking of the plate and frame, and inconvenience of use. Therefore, a plate and frame lifting device for a plate and frame filter press is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A plate and frame hanger for a plate and frame filter press includes:

[0008] The overhead crane has guide rails fixedly installed on its top inner wall;

[0009] A linear motor is slidably connected to the bottom of the guide rail;

[0010] A winch and a fixed frame are fixedly mounted on the bottom of the linear motor, with the winch located inside the fixed frame.

[0011] A steel wire rope is wound around one side of the winch, and its end is fixedly connected to the first hook.

[0012] The main body of the lifting device has an inverted V-shaped hanging rod welded to its surface, and the hanging rod is suspended from the first hook;

[0013] Two sets of stabilizing mechanisms connect the fixed frame and the main body of the lifting device, including a first mounting seat fixed to the inner wall of the fixed frame and a second mounting seat fixed to the surface of the main body of the lifting device;

[0014] Two sets of lifting mechanisms are located at both ends of the lifting device for hooking the plate frame;

[0015] The stabilizing mechanism limits the swing amplitude of the lifting device body during lifting, translating and moving.

[0016] In one possible design, the stabilizing mechanism further includes a first rotating shaft rotatably connected to both sides of the first mounting base and a second rotating shaft rotatably connected to both sides of the second mounting base. The outer wall of the first rotating shaft is fixedly sleeved with a sleeve, and the outer wall of the second rotating shaft is fixedly connected with an inner rod, which is slidably inserted into the sleeve.

[0017] When the main body of the lifting device is raised or lowered, the inner rod and the sleeve slide relative to each other.

[0018] In one possible design, the inner walls on both sides of the first mounting base are provided with first bolts, which are threadedly connected to the side walls of the fixing frame.

[0019] In one possible design, two third bolts are provided through the surface of the second mounting base, and the third bolts are threadedly connected to the surface of the lifting device body;

[0020] The bottom of the second mounting base is provided with a positioning groove that fits into the outline of the lifting device body.

[0021] In one possible design, the lifting mechanism includes a mounting rod that slides through the bottom of the lifting device body, with a nut threaded onto the top of the mounting rod, a chain fixedly connected to the bottom, and a second hook fixed to the end of the chain.

[0022] In one possible design, the axes of the first and second rotating shafts are parallel to each other and perpendicular to the lifting direction of the lifting device body.

[0023] In one possible design, when the main body of the spreader is raised or lowered, the sliding fit between the inner rod and the sleeve constrains the lateral displacement; when the linear motor moves horizontally, the rigid connection between the sleeve and the inner rod transmits the driving force and suppresses the resonance of the spreader body.

[0024] In this application, when replacing the plate and frame filter press, the overhead crane is moved to the processing position, and the winch is started using a remote control to lower the main body of the lifting device. During the lifting and lowering of the main body of the lifting device, the sleeve and the installation rod slide automatically and relative to each other, so that the main body of the lifting device moves stably. Then, the second hook is manually adjusted to hook the plate and frame filter press, and then the winch is used to lift the main body of the lifting device and the plate and frame filter press. Then, the linear motor is started to drive the main body of the lifting device and the plate and frame filter press to move horizontally. The winch is then used to lower the plate and frame filter press to the ground. After replacing it with a new plate and frame filter press, the winch is used again to lift the main body of the lifting device and the plate and frame filter press. The linear motor is controlled to drive the main body of the lifting device and the new plate and frame filter press to move above the plate and frame filter press. Then, the plate and frame filter press is lowered and installed. After the installation is completed, the second hook can be removed.

[0025] Beneficial effects: In this utility model, the plate and frame hanger of the plate and frame filter press, through the setting of the first mounting seat, the second mounting seat and the sleeve and other structures, can limit the lifting and translation of the main body of the hanger, so that the movement of the main body of the hanger and the plate and frame is more stable and the swaying amplitude is reduced.

[0026] In this utility model, the plate and frame hanger of the plate and frame filter press, through the setting of the first mounting base, the second mounting base and the mounting rod, etc., makes the overall hanger easy to assemble and disassemble, providing convenience for people and facilitating later maintenance;

[0027] In this utility model, the lifting and translation of the main body of the lifting device can be limited, making the movement of the main body and the frame of the lifting device more stable, reducing the sway amplitude, and making the overall assembly and disassembly of the lifting device convenient, providing convenience for people and facilitating later maintenance.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] In one embodiment: Refer to Figures 1-4A lifting device includes: a crane 1, which serves as a mobile base, with a parallel guide rail 2 fixedly installed on its top inner wall, and a linear motor 3 slidably connected to the bottom of the guide rail 2. The bottom of the linear motor 3 is rigidly connected to a fixed frame 7 and a winch 4, wherein the winch 4 is located inside the cavity of the fixed frame 7. A wire rope 5 of the winch 4 is wound around its drum, and its end is fixedly connected to a first hook 6.

[0035] The main body 8 of the lifting device is a plate-frame load-bearing structure, with an inverted V-shaped hanging rod 9 welded to its top surface. The V-shaped opening of the hanging rod 9 hangs downward from the first hook 6. Two sets of stabilizing mechanisms are symmetrically arranged between the fixed frame 7 and the main body 8 of the lifting device. Each set of mechanisms includes a first mounting seat 10 and a second mounting seat 11. The first mounting seat 10 is vertically fixed to the inner wall of the fixed frame 7, and the second mounting seat 11 is vertically fixed to the top surface of the main body 8 of the lifting device.

[0036] The core linkage components of the stabilizing mechanism include: a first rotating shaft 12 horizontally connected to both sides of a first mounting base 10 via bearings, and a second rotating shaft 17 symmetrically connected to both sides of a second mounting base 11. A sleeve 13 is fixedly fitted onto the outer wall of the first rotating shaft 12, and an inner rod 18 is fixedly connected to the outer wall of the second rotating shaft 17. The sleeve 13 and the inner rod 18 form an axial sliding pair, allowing the inner rod 18 to extend and retract within the sleeve 13 during the lifting and lowering of the lifting device body 8, while simultaneously adapting to angular deflection through the rotation of the rotating shafts. This structure ensures that the lifting device body 8 is always under bidirectional mechanical constraint during lifting and lowering, eliminating lateral sway.

[0037] The lifting mechanism is symmetrically arranged at both ends of the lifting body 8: the mounting rod 21 slides through the bottom through hole of the lifting body 8, and its top extends to the top of the lifting body 8 and is threaded with a nut 24. Tightening the nut 24 locks the lifting position of the mounting rod 21. The bottom end of the mounting rod 21 is connected to a chain 22, and the end of the chain 22 is fixed with a second hook 23. By adjusting the insertion depth of the mounting rod 21, the lifting height can be adapted to plates and frames of different thicknesses.

[0038] This application can be used in the field of plate and frame processing, as well as in other fields applicable to this application.

[0039] In another embodiment: a plate and frame hanger for a plate and frame filter press, which is applied to the plate and frame processing field;

[0040] In another aspect of this embodiment, the fixing frame 7 and its components are assembled in a modular fashion: first bolts 14 are installed through the inner walls of both sides of the first mounting base 10, and the first bolts 14 are threadedly connected to the side walls of the fixing frame 7 for fastening. Two third bolts 19 are installed through the top surface of the second mounting base 11, and the third bolts 19 mate with the threaded holes on the top surface of the lifting device body 8. L-shaped mounting plates 15 are welded to both sides of the fixing frame 7, and second bolts 16 are installed through the bottom of the mounting plates 15, and the second bolts 16 are threadedly connected to the bottom of the linear motor 3. A positioning groove 20 is provided at the bottom of the second mounting base 11, which fits into the top edge contour of the lifting device body 8 to prevent radial displacement during installation.

[0041] The lifting device is positioned, and the linear motor 3, remotely activated, moves along the guide rail 2 to the plate and frame replacement station. The winch 4 releases the wire rope 5, and the lifting device body 8 descends under gravity. At this time, the sleeve 13 and the inner rod 18 slide relative to each other: when the lifting device body 8 descends, the inner rod 18 extends from the sleeve 13; when it rises, the inner rod 18 retracts. The rotating shaft structure compensates for the swing angle of the lifting device, ensuring that the sleeve 13 and the inner rod 18 always slide coaxially. This process uses mechanical constraints to suppress the sway amplitude of the lifting device body 8, controlling the lifting trajectory deviation within ±5°.

[0042] During the hoisting of the plate frame, the second hook 23 is manually pulled to engage the lifting lug of the plate frame. When the winch 4 tightens the wire rope 5, the main body of the lifting device 8 drives the plate frame to rise. The inner rod 18 of the stabilizing mechanism retracts into the sleeve 13, while the rotating shaft rotates freely to eliminate torsional load. When the linear motor 3 drives the fixed frame 7 to move horizontally, the rigid connection between the sleeve 13 and the inner rod 18 evenly transmits the lateral driving force to the main body of the lifting device 8, avoiding resonance in the hoisting system.

[0043] During maintenance and disassembly, when removing the second mounting base 11, loosening the third bolt 19 allows the stabilizing mechanism to separate from the lifting body 8; when removing the first mounting base 10, loosening the first bolt 14 allows separation from the fixing frame 7. The cooperation between the mounting plate 15 and the second bolt 16 allows the linear motor 3 to be disassembled independently.

[0044] However, as is well known to those skilled in the art, the working principles and wiring methods of the linear motor 3 and the winch 4 are commonplace and are all conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0045] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
