Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Dismantle the process fragile for solving the sealed carbocycle of present impeller seal usefulness, and dismantle the problem of inefficiency, the utility model particularly provides an air compressor carbocycle is dismantled and is used connecting rod sled formula frock, this frock simple structure, the cost of manufacture is low, and it is convenient to use, can effectively improve the dismantlement efficiency of carbocycle, and dismantles the process and can not cause the damage to the carbocycle. For further explanation of the structure of the present invention, the following detailed description is made with reference to the accompanying drawings:

referring to fig. 1 and 2, a link lever prying tool for disassembling a carbon ring of an air compressor includes a pulling frame 1 and a prying wrench 2. The pull frame 1 is a component used for being connected with the carbon ring, and the prying wrench 2 is a tool component used for prying the pull frame 1.

The pull frame 1 comprises a vertical hanging plate 1-1 and a transverse pull plate 1-2 connected with the vertical hanging plate 1-1, the vertical hanging plate 1-1 is provided with a bolt through hole, and a plurality of prying holes 1-3 are uniformly distributed on the transverse pull plate 1-2 along the length direction. Specifically, the vertical hanging plate 1-1 and the transverse pulling plate 1-2 are mutually perpendicular and welded steel plates, and a triangular rib plate is welded at the connecting angle of the vertical hanging plate 1-1 and the transverse pulling plate 1-2 so as to strengthen the tensile strength of the connecting part of the vertical hanging plate 1-1 and the transverse pulling plate 1-2. In this embodiment, the transverse pulling plate 1-2 is connected to the middle of the vertical hanging plate 1-1, the upper and lower ends of the vertical hanging plate 1-1 are respectively provided with a bolt through hole for inserting the bolt 3, the bolt 3 is connected to a process screw hole of the carbon ring, and the diameter of the bolt through hole must be smaller than the diameter of a screw rod of the bolt 3, so as to ensure that the transverse pulling plate 1-2 can apply a pulling force to the carbon ring through the bolt 3.

The prying wrench 2 is provided with a prying rod 2-1, the prying rod 2-1 is inserted in a prying hole 1-3 of the transverse pulling plate 1-2, and a prying handle 2-2 is arranged at the upper end of the prying rod 2-1. Specifically, the pry bar 2-1 is of a round bar-shaped structure, the lower end part of the pry bar 2-1 is of a circular arc head shape, and the lower end of the pry bar 2-1 is sleeved with the rubber sleeve.

During the use, the vertical link plate 1-1 of the pull frame 1 is connected with the carbocycle of waiting to dismantle through the bolt 3 of through bolt through-hole, and the horizontal arm-tie 1-1 of pull frame 1 extends along the axial of carbocycle, and the extension length exceeds the distance of carbocycle to semi-annular recess. Prying rod 2-1 of prying spanner 2 is inserted into a prying hole which is located between the semi-annular groove and the carbon ring and is closest to the semi-annular groove, the lower end of prying rod 2-1 of prying spanner 2 is clamped into the semi-annular groove, prying handle 2-2 of prying spanner 2 is pulled in the direction away from the carbon ring, under the action of a lever principle, pulling frame 1 is pulled by one end distance in the axial direction, the carbon ring is pulled out by one end length in the axial direction, prying rod 2-1 of prying spanner 2 is inserted into the next prying hole, and the carbon ring is pulled out completely section by section so as to realize disassembly.

In the embodiment, the two pull frames 1 are included, the prying wrench 2 includes a transverse plate 2-3 and two prying bars 2-1 symmetrically fixed on the lower portion of the transverse plate 2-3, the two prying bars 2-1 are respectively combined with prying holes 1-3 of the two pull frames 1, the transverse plate 2-3 and the two prying bars 2-1 form an inverted U-shaped structure, and the prying bars 2-2 are fixed in the middle of the transverse plate 2-3 and extend upwards. This structure is guaranteed that a pulling action acts on four whole technology screw hole departments of carbocycle, and the axial atress of carbocycle on the circumferencial direction is more even, makes the dismantlement process lighter, and more important can guarantee that the carbocycle bears minimum radial stress at the in-process of being pulled out, guarantees the quality. The bridge frame 4 is connected between the two pulling frames 1, the bridge frame is an arc-shaped steel frame body, the pulling frames are welded, and the two pulling frames 1 are connected into an integral structure through the bridge frame 4. The structure further ensures the synchronism of pulling in the circumferential direction of the carbon rings.
