Detailed Description

Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. It should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "front", "rear", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, which are for convenience of description only, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

A screen basket dismounting tool of a horizontal centrifuge is used for dismounting a screen basket 2 on a main shaft 1. The main shaft 1 is provided with a male spigot and a flange for connecting the screen basket 2, and the flange is provided with a plurality of threaded holes. The bottom of screen basket 2 is equipped with the connecting hole that corresponds with the screw hole, and screen basket 2 passes through bolted connection on the flange of main shaft 1. In order to solve the problems in the background art, as shown in fig. 2, two process threaded holes and a central hole are arranged on the end surface of the male end of the main shaft 1.

The disassembling tool for the screen basket 2 comprises a guide pillar 3 and a sliding sleeve 6. The cross section of the guide post 3 is rectangular, and the left end of the guide post 3 is provided with a connecting disc 4. The connecting disc 4 is a disc body, the diameter of the connecting disc 4 is equal to that of the convex spigot of the main shaft 1, and the connecting disc 4 is provided with a chamfer. The chamfer has a guiding effect on the screen basket 2 and is beneficial to the matching installation of the screen basket 2 on the convex spigot of the main shaft 1. The connecting disc 4 is provided with connecting holes corresponding to the two technical threaded holes, and the connecting disc 4 is fixed on the end surface of the convex spigot of the main shaft 1 through a screw 5. In order to ensure the coaxiality of the connecting disc 4 and the main shaft 1, the connecting disc 4 is provided with a pin shaft corresponding to the central hole, and the pin shaft is matched with the central hole to ensure the coaxiality of the connecting disc 4 and the main shaft 1. It is worth noting that the two process threaded holes on the male spigot end face and the threaded holes on the flange of the main shaft 1 have an angular position relationship.

The sliding sleeve 6 can slide along the guide post 3. Because the rectangular guide post 3 and the main shaft 1 have a coaxial relationship, the sliding sleeve 6 can not rotate under the guidance of the rectangular guide post 3, and can only slide along the rectangular guide post 3, and the sliding sleeve 6 and the main shaft 1 have a coaxial relationship. The left end of the sliding sleeve 6 is a hollow sleeve body provided with an outward flange, and the hollow sleeve body can be sleeved into a cavity of the convex spigot of the main shaft 1. The flanging edge is at least provided with two through positioning pin 7 holes in the axial direction, and the positioning pin 7 is detachably matched and connected in the positioning pin 7 holes. Locating pin 7 is stepped shaft structure, and great axial region is connected with the connecting hole cooperation of basket 2 for connect fixed basket 2. The smaller shaft part has a chamfer and can be inserted into a threaded hole of the flange of the main shaft 1. It should be noted that the two connecting holes on the connecting plate 4 and the positioning pin 7 on the sliding sleeve 6 also have an angular position relationship.

The right end of the sliding sleeve 6 is connected with a connecting rod mechanism. The connecting rod mechanism comprises a driving connecting rod 8 and a driven connecting rod 9, wherein the driving connecting rod 8 is hinged on the guide pillar 3. One end of the driven connecting rod 9 is hinged on the sliding sleeve 6, and the other end is hinged at the middle part of the driving connecting rod 8. In this embodiment, the linkage mechanisms are two sets, and the two sets of linkage mechanisms are symmetrically arranged about the guide post 3. The free end of the active connecting rod 8 is provided with a handle, and the sliding sleeve 6 can slide leftwards or rightwards along the guide pillar 3 by pushing the active connecting rod 8 to rotate. The link mechanism is a type of labor-saving lever, applies a small acting force to the driving link 8, and can generate a large thrust to the sliding sleeve 6.

When installing basket 2, fix basket 2 on the left end face of sliding sleeve 6 through locating pin 7 earlier, then fix connection pad 4 on the terminal surface of main shaft 1 tang through screw 5. Then the driving connecting rod 8 is pulled inwards, at the moment, the sliding sleeve 6 pushes the screen basket 2 to move leftwards, and the screen basket 2 is sleeved on the convex spigot of the main shaft 1. Because two process threaded holes on the end face of the male end have an angular position relation with the threaded holes on the flange of the main shaft 1, and two connecting holes on the connecting disc 4 also have an angular position relation with the positioning pins 7 on the sliding sleeve 6, the positioning pins 7 can have a corresponding relation with the threaded holes on the flange. The head of the positioning pin 7 can be inserted into a threaded hole of the flange of the main shaft 1, so that the centering precision is further improved. And finally, dismantling the tool, and fixing the screen basket 2 on the flange of the main shaft 1 through bolts.

When the screen basket 2 is disassembled, firstly, the fastening bolts of the screen basket 2 and the positioning pins 7 on the sliding sleeves 6 are disassembled, and then the connecting disc 4 is fixed on the end surface of the convex spigot of the main shaft 1 through the screws 5. And riveting a positioning pin 7 hole on the sliding sleeve 6 and a connecting hole on the screen basket 2 together by using a riveting gun, and then pulling the driving connecting rod 8 outwards to pull the screen basket 2 out of the main shaft 1. Finally, the rivets are ground off.

The present invention is not described in detail in the prior art. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
