Description

Technical Field

[0001] This utility model relates to the field of mixing bottom shaft head disassembly and assembly technology, and in particular to a special device for disassembling and assembling mixing bottom shaft heads. Background Technology

[0002] In the maintenance of large-scale mixing equipment, the replacement of the mixing bottom shaft head or bottom shaft sleeve requires disassembly and installation. During maintenance, the large amount of labor required or the difficulty of disassembly and installation often leads to accidents such as crushing and crushing injuries to personnel. Therefore, it is necessary to use a special device for disassembling and installing the mixing bottom shaft head to improve the disassembly efficiency.

[0003] A search revealed that patent CN201906582U discloses a corrosion-resistant, detachable bottom bearing device for a stirring shaft. The device includes a housing for mounting the stirrer, an inner corrosion-resistant plastic liner, a limiting flange mounted on the housing, and a corrosion-resistant plastic hub plate sandwiched between two housings. The two housings are connected as one unit by bolts to the limiting flange. A corrosion-resistant plastic sliding bearing for mounting the stirring shaft is mounted on the hub plate. This invention, by tightening the housing, limiting flange, anti-rotation positioning plate, and corrosion-resistant plastic liner with bolts, generates a preload on the hub plate. This preload ensures that the bottom bearing device maintains concentricity and sealing with the stirring shaft under internal pressure, allowing the stirring shaft to operate normally within the device. This invention has the advantages of simple structure, improved corrosion resistance of the stirrer, and extended service life.

[0004] However, existing mixing bottom shaft head disassembly and assembly devices are not convenient to assemble and install during use, resulting in low disassembly efficiency. Therefore, there is an urgent need in the market for a dedicated disassembly and assembly device for mixing bottom shaft heads to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a special device for disassembling and assembling the mixing bottom shaft head, so as to solve the problem mentioned in the background art that the existing mixing bottom shaft head disassembly and assembly device cannot be easily spliced ​​and installed during use, thus resulting in low disassembly efficiency.

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

[0007] A special device for disassembling and assembling a stirring base includes a mounting base, with mounting rods at both ends of the mounting base. Each end of the mounting rod has a threaded mounting groove. The mounting base has a positioning mounting groove inside, with a through mounting groove at the lower end of the positioning mounting groove. Connecting rods are mounted on both sides of the mounting rods. A threaded connecting seat is provided at the end of the connecting rod closest to the mounting base, and a handle is mounted on the outside of the end of the connecting rod furthest from the mounting base. A fixing pin is mounted on the mounting base.

[0008] By adopting the above technical solution, the mixing bottom shaft head disassembly and assembly device can be easily assembled and disassembled, thereby improving work efficiency.

[0009] Furthermore, the fixing pin includes a limiting seat, a threaded mounting end, and a rotating pin seat. One end of the limiting seat is provided with the threaded mounting end, and one end of the threaded mounting end is provided with the rotating pin seat.

[0010] Furthermore, the limiting seat and the threaded mounting end are an integral structure, and the threaded mounting end and the rotating pin seat are an integral structure.

[0011] Furthermore, two mounting rods are provided, symmetrical about the vertical center line of the mounting base, and the mounting base and the mounting rods are an integral structure. By adopting the above technical solution, the structure between the mounting base and the mounting rods is made more robust, thus avoiding the possibility of breakage between the mounting base and the mounting rods.

[0012] Furthermore, two connecting rods are provided, and the threaded connecting seat and the connecting rod are integrally formed. The threaded connecting seat and the threaded mounting groove are connected by threads. By adopting the above technical solution, the thread can easily connect the threaded connecting seat and the threaded mounting groove, thus enabling the connecting rod and the mounting rod to be installed and fixed.

[0013] Furthermore, friction ropes are provided around the outer wall of the handle at the end away from the mounting base. Several friction ropes are arranged sequentially around the outer wall of the handle. By adopting the above technical solution, the friction ropes can increase the friction between the handle and the hand, thus preventing the disassembly / assembly device from detaching from the hand during use, which would affect the effectiveness of the device.

[0014] Furthermore, the limiting seat fits into the positioning mounting groove, with the limiting seat located inside the positioning mounting groove, and one end of the rotating pin seat passing through the positioning mounting groove and extending to the outside. By adopting the above technical solution, the fixing pin can be conveniently limited and installed, avoiding the fixing pin from easily shaking during use, thus affecting the effectiveness of the fixing pin.

[0015] Furthermore, the rotating pin seat and the mounting seat are fixedly connected by a fixing nut, and the fixing nut is engaged with the threaded mounting end.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) This utility model installs the threaded connecting seat of the connecting rod into the threaded mounting groove of the mounting rod, so that the connecting rod and the mounting rod can be installed conveniently. Then, one end of the fixing pin passes through the mounting seat and extends to the outside of the mounting seat, so that the limiting seat is located inside the positioning mounting groove. Then, by installing the fixing nut on the outside of the threaded mounting end, the fixing nut is installed between the mounting seat and the fixing pin. This allows the disassembly and assembly device to be easily spliced ​​and installed, making the disassembly and assembly device more convenient to use and allowing for easy disassembly and assembly of the mixing bottom shaft head.

[0018] (2) The present invention can protect the hands when disassembling and assembling the mixing bottom shaft head by setting the handle. The friction rope can increase the friction between the handle and the hand, thereby avoiding slippage between the hand and the handle, which would affect the disassembly and assembly efficiency.
