Description

Technical Field

[0001] This utility model relates to the field of screw pump technology, and in particular to a screw pump rotor disassembly and assembly device. Background Technology

[0002] In existing technology, screw-type mortar pumps belong to the single-screw pump category. The main working components of a single-screw pump are an eccentric helical screw (called the rotor) and a screw bushing (called the stator) with a double-helix inner surface. Its working principle is that when the motor drives the pump shaft to rotate, the screw rotates around its own axis while simultaneously rolling along the inner surface of the bushing, thus forming the pump's sealed chamber. A single-screw pump consists of a steel sleeve, a rubber stator bushing, and a single-helix rotor, and can be used for mortar pumping in the construction industry.

[0003] A search revealed Chinese patent application number 202221806874.2, which discloses a screw pump assembly / disassembly device, comprising: a mounting frame, a drive assembly, a sliding assembly, and a positioning assembly; the drive assembly is mounted on the mounting frame and includes a motor and a coupling, the output shaft of which is connected to the rotor of the screw pump via the coupling; the sliding assembly is movably mounted on the mounting frame and can move toward or away from the drive assembly; the positioning assembly includes a stop structure and two stop seats, the two stop seats being spaced apart on the sliding assembly and used to clamp the stator from both ends of the screw pump stator respectively, the stop seat located near the drive assembly having a first through hole for the rotor to pass through, and the stop seat also having a stop structure.

[0004] The aforementioned patent has the following shortcomings: The screw (rotor) of the single screw pump is fixedly connected to the connecting rod shaft and installed inside the steel cylinder for slurry pumping. The connecting rod shaft is connected to the motor through a bearing housing. When disassembling the screw (rotor), the steel sleeve must first be removed, and then the screw is fixed. The connection between the screw and the connecting rod shaft is generally set in two ways: pin connection or flange. The screw and the connecting rod shaft are disassembled and assembled using corresponding equipment (pin punch or wrench). Since the screw needs to withstand a large torque and the connection between it and the connecting rod shaft is relatively tight, the existing equipment is cumbersome to disassemble and assemble.
