Description

Technical Field

[0001] This utility model relates to the field of hoisting mechanism technology, specifically to an automatic clamping and hoisting mechanism for a sludge cutting machine grid. Background Technology

[0002] The sludge cutter grid is a key component in sludge treatment equipment. It is usually installed at the inlet of sludge conveying pipelines or sludge treatment equipment. Its main function is to intercept and cut large solid impurities and fibrous materials in sludge, preventing these impurities from clogging pipelines or damaging subsequent treatment equipment. The grid is usually made of metal and has regularly arranged pores or blades, which can effectively separate and break the solid components in sludge, ensuring smooth sludge passage and improving the operating efficiency and reliability of the entire sludge treatment system. The automatic clamping and hoisting mechanism for sludge cutting machine grids is an automated device specifically designed for sludge treatment equipment. Its core function is to automatically clamp and hoist the sludge cutting machine grids. This mechanism is usually equipped with mechanical grippers or grabbing devices that can hold the grids and lift and move them to a designated position through a hoisting system. Traditional clamping devices rely primarily on the lifting and lowering action of cylinders to lift and lower the screen after clamping. However, in environments with limited indoor space, this method of relying on a single cylinder or hydraulic cylinder for lifting and lowering has limitations. Due to the limited indoor height, the stroke of the cylinder or hydraulic cylinder may not be sufficient to lift the screen to the required height or lower it to the designated position, thus affecting the convenience and applicability of the entire clamping device in practical applications. Therefore, to address the above problems, an automatic clamping and lifting mechanism for sludge cutting machine screens is proposed. Utility Model Content

[0017] As a further implementation of this solution, the guide cylinder 17 is inserted into the fixing hole 23 opened in the lifting seat 21, and the guide cylinder 17 is fixedly connected to the lifting seat 21 by bolts. It should be noted that the plug-in and bolt-fixing design of the guide cylinder 17 provides a stable and easy-to-install connection method, ensuring a firm connection between components; Furthermore, this design enhances the structural stability of the entire mechanism, helps maintain precise alignment and operational reliability during hoisting, thereby improving the operational safety and durability of the device.

It should be noted that: the rotation of the clamping plate 41 is controlled, and the rotation angle of the clamping plate 41 is also controlled. The design of the clamping component 4 allows for flexible rotation and connection, making the clamping and releasing operations smoother.

[0018] Workflow: When hoisting the sludge cutter bar screen body 5 in an indoor space with limited height, the top plate 11 is fixed to the module or drive structure. The position is controlled by the existing module or other drive mechanism until the two clamping components 4 are located at the upper end of the sludge cutter bar screen body 5. At this time, the starting cylinder 27 extends, and the piston rod of the cylinder 27 slides inside the movable hole 22, simultaneously driving the built-in column 16 to move upwards. The built-in column 16 pushes the folding frame 15 to unfold. Simultaneously, the lower end of the folding frame 15 drives the two sliding columns 26 to move. The sliding column 26 slides inside the built-in sliding groove 25 of the lifting seat 21 via a rotating connection. The upper end of the folding frame 15 slides inside the first guide rail 13 via the upper sliding column 26. At this time, the distance between the top plate 11 and the lifting seat 21 is greater. At the same time, the guide rod 14 slides inside the guide cylinder 17. The limiting of the guide rod 14 and the guide cylinder 17 can control the stability of the assembly between the lifting seat 21 and the top plate 11. The lower end of the guide rod 14 is fixed with a limit piece to prevent the guide rod 14 from disengaging from the guide cylinder 17. When the lifting seat 21 moves downward to the sludge cutter, the limiting support assembly 3 and the clamping assembly 4 move downward to the sludge cutter. After a certain distance above the sludge cutter screen body 5, the starting cylinder 45 retracts, causing the two bearing seats 44 to move closer together. The bearing seats 44 are rotatably connected to the extension plate 43, and the extension plate 43 causes the clamping plate 41 to rotate around the shaft column 32. When the clamping plate 41 is tightly against the second limit bolt 34, the second limit bolt 34 acts as a limit when clamping the two clamping plates 41, and the first limit bolt 33 acts as a limit when unfolding the two clamping plates 41. The clamping plate 41 is held by the sludge cutter screen body 5 through the clamping groove 42. At this time, the control cylinder 27 retracts, and the internal... The column 16 drives the folding frame 15 to retract, and the guide rod 14 slides towards the lower end of the lifting seat 21. The shape design of the sludge cutter screen body 5 does not affect the downward movement of the guide rod 14, thereby achieving the effect of lifting the lifting seat 21 and the sludge cutter screen body 5 upward. Based on the above principles, the device changes the traditional method of lifting and lowering by simply driving the equipment. By controlling the length of the cylinder 27 and the small stroke of the piston, the device can perform a wide range of lifting and lowering operations. This significantly controls the space occupied by the device, making it suitable for use in indoor environments with limited height, and improving the convenience and applicability of the device in practical applications.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
