Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of slurry pump maintenance equipment, and in particular relates to a protective plate hoisting device. Background Technology
[0002] Slurry pumps are key equipment in mining, metallurgy, and power industries for transporting high-concentration abrasive slurries, and their liner plates, as vulnerable components, require regular replacement. Currently, the liner plates are often hoisted using wire ropes or general-purpose lifting tools for direct binding and fixing, which presents the following problems:
[0003] Low positioning accuracy: The guard plate has an arc structure and needs to fit tightly with the pump body. Traditional hoisting methods cannot guarantee vertical hoisting and alignment during assembly, resulting in low installation efficiency and easy damage to the guard plate or pump body interface.
[0004] Poor stability: The protective plate is prone to shaking, tilting, or even slipping during hoisting, posing a safety hazard.
[0005] Insufficient adaptability: General-purpose lifting tools cannot adapt to the curved surfaces of different sizes of guard plates, requiring frequent manual adjustments and increasing the workload.
[0006] To solve the above problems, a hoisting device specifically designed for slurry pump liner plates needs to be designed to achieve rapid fixing, vertical hoisting, and precise assembly. Utility Model Content

[0027] Please see Figure 1-3 To achieve the above objectives, this embodiment provides a protective plate hoisting device, which consists of four parts: protective plate 1, hoisting rod 2, connecting block 3, and fixing device. The components work together to achieve stable hoisting and assembly of the protective plate 1.
[0028] In this embodiment, the guard plate 1 has an arc-shaped structure, and its curvature design matches the side wall shape of the mud pump, allowing it to fit tightly against the pump body surface. A first fixing plate 4 and a second fixing plate 5 are respectively fitted onto both ends of the guard plate 1, forming an annular surrounding structure.
[0029] In this embodiment, the boom 2 is connected to the guard plate 1 via a connecting block 3. A groove is provided on one side of the connecting block 3, allowing the guard plate 1 to be embedded within and move within a limited range along the groove, facilitating position adjustment. The connecting block 3 and the guard plate 1 are fastened together with bolts to ensure reliable connection. One end of the boom 2 passes through the connecting block 3 and has a protrusion at the end to prevent the boom 2 from detaching from the connecting block 3; a lifting hole 8 is provided on the side wall of the boom 2 for connecting lifting equipment (such as a hook or rope).
[0030] In this embodiment, the fixing device consists of a first fixing plate 4, a second fixing plate 5, and a connector. The first fixing plate 4 is sleeved on one end of the protective plate 1, and the second fixing plate 5 is sleeved on the other end. The two are quickly connected and locked by the connector. The connector specifically includes a first connecting block 63 fixed to the first fixing plate 4 and a second connecting block 73 fixed to the second fixing plate 5. The side wall of the first connecting block 63 is provided with a plug rod, which can be inserted into the corresponding hole in the side wall of the second connecting block 73 to form a plug-in fixing.
[0031] In this embodiment, both the first fixing plate 4 and the second fixing plate 5 are further reinforced on the side wall of the guard plate 1 by fixing rods to prevent the fixing plates from shifting or loosening during hoisting.
[0032] In this embodiment, the protective plate 1 serves as the main body to be hoisted, and its arc-shaped design directly fits the pump body to protect the internal structure of the pump from wear or impact.
[0033] In this embodiment, the boom 2 bears the main lifting force and is connected to the external lifting equipment through the lifting hole 8; the connecting block 3 serves as an intermediate carrier, which both fixes the guard plate 1 and transmits the lifting force. Its channel design allows the guard plate 1 to be finely adjusted in position, which is convenient for alignment and installation.
[0034] In this embodiment, the first fixing plate 4 and the second fixing plate 5 clamp the two ends of the guard plate 1 to form a closed ring structure, which enhances the overall rigidity of the guard plate 1; the plug-in connector enables quick assembly and disassembly, and can be fixed or released without tools, thus improving operational efficiency.
[0035] In this embodiment, the fixing rod helps to strengthen the connection between the fixing plate and the guard plate 1, preventing loosening due to vibration or shaking during hoisting.
[0036] Working principle
[0037] Lifting preparation stage: Insert the first fixing plate 4 and the second fixing plate 5 onto both ends of the protective plate 1, and initially fix them with fixing rods. Install the connecting block 3 in the preset position on the protective plate 1 with bolts, and let the lifting rod 2 pass through the connecting block 3 and be limited by the end protrusion.
[0038] Closing and Locking, and Lifting: Wrap the protective plate 1 around the outside of the pump body, align the first fixed plate 4 with the second fixed plate 5, and insert the insertion rod to complete the quick locking. The lifting equipment lifts the device through the lifting hole 8 of the lifting rod 2, and the protective plate 1 maintains a stable posture under the traction of the lifting rod 2.
[0039] Assembly and Adjustment: After hoisting to the pump body installation position, fine-tune the angle of the protective plate 1 through the groove of the connecting block 3 to ensure it is fully flush with the pump side wall. After confirming the position, tighten the bolts, remove the lifting rod 2 and fixing device, and the installation is complete.
[0040] In other embodiments, the guard plate 1 may be made of high wear-resistant alloy steel or rubber composite material to adapt to different working conditions; the fixing plate and the connecting parts are heat-treated or galvanized for corrosion protection to extend their service life.
[0041] In other embodiments, a safety pin or self-locking mechanism is added to the connection of the plug rod to prevent accidental detachment during hoisting; multiple lifting holes 8 are added to the side wall of the lifting rod 2 to adapt to the hook size of different lifting equipment.
[0042] In other embodiments, this device is not only applicable to mud pump liner 1, but can also be used for the hoisting and assembly of other large arc-shaped components (such as pipe liners and crusher walls), achieving rapid adaptation through modular design.
[0043] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
