Detailed Description

The embodiment of the application provides a dismantlement frock of tension connecting pin axle, has solved the technical problem that can't use the puller to dismantle large-scale mechanical equipment's big plane department tension connecting pin axle among the correlation technique.

In order to solve the technical problems, the general idea of the embodiment of the application is as follows:

the utility model provides a dismantlement frock of tension connecting pin axle for dismantle the tension connecting pin axle of equipment body, dismantle the frock and include bottom plate, bracing piece and jack, bracing piece one end is fixed in the bottom plate, and the bracing piece other end is fixed in the equipment body, and the jack is located between bottom plate and the equipment body, and the base of jack is fixed in the bottom plate, and the top and the tension connecting pin axle butt of jack are in order to dismantle tension connecting pin axle from the equipment body.

In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.

Referring to fig. 1 and fig. 2, the present embodiment provides a disassembling tool 10 for an over-tightened connecting pin 21, which is used for disassembling the over-tightened connecting pin 21 of an apparatus body 20. This dismantlement frock 10 includes bottom plate 11, bracing piece 12 and

jack

13, and 12 one ends of bracing piece are fixed in bottom plate 11, and the bracing piece 12 other end is fixed in equipment body 20, and jack 13 locates between bottom plate 11 and the equipment body 20, and the base of jack 13 is fixed in bottom plate 11, and jack 13's top is with the 21 butt of tension connecting pin axle to dismantle from equipment body 20 with tension connecting pin axle 21.

Wherein, bottom plate 11 is fixed in equipment body 20 through bracing piece 12, and bracing piece 12 cooperates bottom plate 11 to provide the operating condition of jack 13, and jack 13 one end supports bottom plate 11, and the other end supports the round pin axle, and the round pin axle of connecting excessively tightly is ejecting, is dismantled from equipment body 20 through jack 13, overcomes the technical problem that can't use the horse puller to dismantle big plane department excessively tight connecting pin axle 21 of large-scale mechanical equipment.

Compared with a mode of directly adopting hammer beating to disassemble, the disassembling tool 10 of the embodiment well protects the pin shaft. In addition, the disassembling tool 10 is simple in overall structure and good in applicability.

The over-tightening connection of the over-tightening connection pin 21 in the present embodiment refers to a degree that the pin is firmly attached to the apparatus body 20 and needs to be detached with assistance by an instrument such as the jack 13.

Optionally, referring to fig. 1 and fig. 2, the disassembling tool 10 includes two support rods 12, and the bottom plate 11 is relatively fixed to the equipment body 20 through the two support rods 12, so that the technical solution not only ensures the stability of the bottom plate 11 when the jack 13 works, but also is beneficial to the simplicity of the overall structure.

Alternatively, as shown in fig. 1 and 2, the jack 13 is provided between the two support rods 12. In other embodiments, in the case where the two support rods 12 are arranged in parallel, the jack 13 may be disposed on the outer side of one support rod 12 compared to the other support rod 12, specifically, the jack 13, the support rod 12 and the other support rod 12 may be arranged in parallel in sequence.

Alternatively, in the manner that one end of the support rod 12 is fixedly connected with the bottom plate 11, welding may be adopted, and a screwing manner may also be adopted.

Alternatively, the bottom plate 11 is made of channel steel, and the support rods 12 may be iron columns for facilitating welding connection.

Alternatively, as shown in fig. 1 and 2, a pull ring 111 is fixed to a side of the base plate 11 away from the support rod 12. After the over-tightened connecting pin 21 is removed, the tool is generally separated from the device body 20, and the separation process is assisted manually or by a hanger via the pull ring 111. The pull ring 111 may be a hand-held point when the tool is attached to the device body 20.

Optionally, one end of the support rod 12 away from the bottom plate 11 is welded to the device body 20, and the disassembling tool 10 is firmly mounted to the device body 20 by welding. In other ways, a screw connection mode can also be adopted.

Alternatively, as shown in fig. 2, a nut 121 is disposed at an end of the support rod 12 away from the bottom plate 11, the nut 121 is welded to the device body 20, and an end of the support rod 12 away from the bottom plate 11 is screwed to the nut 121. Compared with the mode that the supporting rod 12 is directly welded to the device body 20, the technical scheme welds the nut 121 to the device body 20, cuts the nut 121 and the device body 20 during disassembly, and can protect the structural integrity of the supporting rod 12 and the bottom plate 11 by replacing the nut 121.

Alternatively, the jack 13 can be a manual jack 13, and the structure is simple, the weight is light, and the operation is convenient.

Optionally, as shown in fig. 2, the disassembling tool 10 is further configured with a separate pad 14, and the separate pad 14 is disposed near a support rod 12 and used for assisting in adjusting the spatial position of the jack 13, so that the base of the jack 13 is fixed to the bottom plate 11, and the top of the jack 13 abuts against the over-tightened connecting pin 21. It should be pointed out that, be the butt relation between the base of jack 13 and the bottom plate 11 among this technical scheme, need not to weld jack 13 at bottom plate 11, be convenient for this dismantlement frock 10 do not use jack 13 in addition for other uses when not using. In other embodiments, it is also possible to weld the jack 13 to the bottom plate 11, but when the support rod 12 is fixed to the device body 20, the abutting of the head of the jack 13 with the over-tightened connection pin 21 is considered.

While preferred embodiments of the present invention have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. Therefore, it is intended that the appended claims be interpreted as including preferred embodiments and all such alterations and modifications as fall within the scope of the utility model.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the utility model. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
