Background

In a thermal power plant, a low-voltage motor is widely used, and the motor is often required to bear various severe environments such as rainwater, oil stains, dust and the like due to different use places and effects of the low-voltage motor.

The low-voltage motor fan is used for cooling the motor, and in the cooling process, rainwater, oil stains, dust and the like can be brought into the low-voltage motor fan through the cooling passage, so that the fan is rusted, sticky with oil and sticky with dust. Therefore, when the motor fan is pulled and detached in the motor maintenance process, the fan is easily broken or cannot be pulled out due to poor force application uniformity. In addition, the models of low-voltage motors in a thermal power plant are various, the sizes of fans are different, the axial distances from the mounting positions of the fans to the dismounting ends are different, and the existing fan dismounting tool has the defects of poor adaptability and incapability of well matching the dismounting requirements of various low-voltage motor fans.

The utility model discloses an above-mentioned problem is solved to following technical means: the utility model provides a pull-out type motor fan extracting tool, includes the base plate, sets up at the top of base plate center and encircles a plurality of drawing claws that top pushed a circumference and evenly set up, the top pushes away the jack type structure that the piece is handstand, and the execution end that pushes away the piece passes the base plate, and the operation end is connected with the handle, drawing the claw and including integrated into one piece's the body of rod and coupler body, the top processing of the body of rod has the screw thread section, the screw thread section passes the base plate and has the nut at top screw thread accordant connection.

Furthermore, a plurality of waist-shaped holes or U-shaped grooves which are in one-to-one correspondence with the drawing claws are processed on the substrate, and the thread sections of the drawing claws penetrate through the corresponding waist-shaped holes or U-shaped grooves and then are tightened on the upper side and the lower side of the substrate through nuts.

Further, the execution end of the pushing piece is provided with a positioning tip.

Further, the positioning tip and the execution end of the pushing piece are integrally formed.

Further, the pushing piece is detachably connected with the base plate through threads.

The utility model has the advantages that: the utility model provides a draw formula motor fan extracting tool, including base plate, set up at the top of base plate center and encircle a plurality of drawing claws that push away a even setting of circumference, the top pushes away the jack type structure that the piece is handstand, and the execution end that pushes away the piece passes the base plate, and the operation end is connected with the handle, draw the claw and include integrated into one piece's the body of rod and coupler body, the top processing of the body of rod has the screw thread section, the screw thread section passes the base plate and has the nut at top screw thread accordant connection. When the fan pushing device is used, the hook body hooks the edge of the fan, and the execution end of the pushing piece is propped against the installation shaft of the fan; the handle is shaken, the fan is separated from the mounting shaft by utilizing the reverse drawing force generated by the pushing piece, and the nut can avoid the separation of the drawing claw and the base plate in the drawing process. By adopting the dismounting tool, the uniformity of stress in the dismounting process of the fan is greatly improved, and the dismounting tool has the advantages of convenience, high efficiency, reliability and wide application range.

Drawings

The invention is further described with reference to the following figures and examples.

Fig. 1 is a schematic structural diagram of an embodiment of the present invention;

fig. 2 is a schematic usage diagram of an embodiment of the present invention.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings, as shown in fig. 1: the drawing type motor fan dismounting tool comprises a base plate 1, a pushing piece 2 arranged at the center of the base plate 2 and a plurality of drawing claws uniformly arranged around the circumference of the pushing piece. The pushing piece 2 is detachably connected with the base plate 1 through threads so as to be convenient to replace; the pushing piece 2 is of an inverted jack type structure, the execution end of the pushing piece 2 penetrates through the base plate 1, and the operation end is connected with a handle 3.

In this embodiment, draw the claw including two distributions in both sides, draw the claw including integrated into one piece's the body of rod 402 and coupler 401, the top processing of the body of rod 402 has screw thread section 403, screw thread section 403 passes base plate 1 and has nut 5 at top screw thread accordant connection, and this nut 5 can avoid when drawing in the axial, draw claw and base plate separation. By adopting the connection mode, the pulling claw can move axially relative to the base plate so as to adapt to the dismounting requirements of fans at different axial depth positions (namely, the dismounting requirements of fans with different axial distances from the mounting position to the dismounting end are met).

As a further improvement of the above technical solution, a plurality of kidney-shaped holes 6 or U-shaped grooves corresponding to the drawing claws one to one are processed on the substrate 1, in this embodiment, the kidney-shaped holes are selected, and the threaded sections 403 of the drawing claws are fastened by nuts 5 on both the upper and lower sides of the substrate after passing through the corresponding kidney-shaped holes 6. By adopting the structure, the radial position of the drawing claw can be adjusted, namely the distance between the drawing claw and the pushing piece is adjusted, so that the disassembling requirements of fans of different sizes are met.

When the fan mounting shaft is used specifically, as shown in fig. 2, the hook body 401 hooks the edge of the fan 8, and the execution end of the pushing piece 2 abuts against the dismounting end of the fan mounting shaft 9; the handle 3 is shaken, and the fan 8 is separated from the fan mounting shaft 9 by using the reverse drawing force generated by the pushing piece 2, thereby realizing the disassembly of the fan 8. In the dismounting process, because the pulling claws are uniformly arranged in the circumferential direction, the fan 8 is uniformly stressed in the circumferential direction, further, the execution end of the pushing piece 2 is integrally provided with a positioning tip 7, and the positioning tip 7 is tightly pressed against the center of the fan mounting shaft 9 during dismounting, so that the stress uniformity of the fan is further improved.

In conclusion, the dismounting tool of the embodiment is adopted, so that the stress uniformity in the dismounting process of the fan is greatly improved, and the dismounting tool has the advantages of convenience, high efficiency, reliability and wide application range.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
