Description
Technical Field
The utility model relates to a frock apparatus especially indicates an axle is with hoist and mount instrument.
Background
Thermal power enterprise, the machinery trade often involves the hoist and mount of axle type equipment, and in the face of large-scale axle type, for example the steam turbine main shaft, often adopt suspender hoist and mount, and in the face of small-size axle type, although adopt suspender hoist and mount or wire rope to bind and lift by crane, but meet the condition that needs the perpendicular lifting by crane, if there is centrifugal fan impeller, the axle is the one-way impeller of extracting, then need the axle to lift by crane perpendicularly and just can extract the impeller, traditional mode suspender of lifting by crane or wire rope can not guarantee that the focus is perpendicular, direct rigid contact, easily cause the slippage and easily cause the precision of axle to go out the problem.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
An object of the utility model is to provide an axle lifting device, can the safety guarantee axle lift by crane perpendicularly, can not damage the axle again, avoid influencing the precision of axle itself. In order to achieve the above purpose, the utility model adopts the following technical proposal:
(II) technical scheme
The utility model provides an axle is with hoist and mount instrument, includes left splint and the right splint that are formed by the steel sheet preparation, left side splint and right splint include linkage segment and joint section, the linkage segment sets up joint section both ends, be equipped with a plurality of connecting hole on the linkage segment, the connecting hole passes through bolt and nut and connects, the joint section is arc design and its inner wall and pastes and have the rubber pads.
Furthermore, three connecting holes are formed in the connecting section, and the connecting holes far away from the clamping section are connected through a U-shaped shackle.
Further, the bolt adopts strength of more than 8.8 grades.
(III) advantageous effects
Compared with the prior art, the utility model obvious advantage and beneficial effect have, particularly, the utility model discloses a left splint and right splint directly cooperate and block the axle, and the rethread loop wheel machine lifts by crane, can the safety guarantee axle lift by crane perpendicularly, avoids the steel sheet directly to contact with axle rigidity again through the protection of rubber pad, can protect the axle, can not influence the precision of axle itself.

Detailed Description
Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
The present invention will be further described with reference to the accompanying drawings and the detailed description.
Referring to fig. 1, the hoisting tool for the shaft comprises a left clamping plate 1 and a right clamping plate 2 which are made of steel plates, wherein the left clamping plate 1 and the right clamping plate 2 comprise a connecting section 21 and a clamping section 22, the connecting section 21 is arranged at two ends of the clamping section 22, a plurality of connecting holes 23 are formed in the connecting section 21, the connecting holes 23 are connected through bolts 3 and nuts 4, the shaft is clamped by the left clamping plate 1 and the right clamping plate 2 through locking of the bolts 3 and the nuts 4 in the later period, the clamping section 22 is in an arc-shaped design, rubber pads 5 are adhered to the inner wall of the clamping section 22, the inner diameter of the clamping section 22 is larger than the diameter of the shaft by about 0-20mm, the inner diameter of the clamping section is smaller than the diameter of the shaft through the thickness of the rubber pads 5, and therefore the shaft can be tightly clamped by the left clamping plate 1 and the right clamping plate 2.
In order to facilitate locking and hoisting, the connecting section 21 is provided with three connecting holes 23, and the connecting holes 23 far away from the clamping section 22 are connected through a U-shaped shackle 6.
In order to avoid breakage during hoisting, the bolt 3 has strength of more than 8.8 grade.
The utility model discloses a left splint and right splint direct cooperation block the axle, and the rethread loop wheel machine lifts by crane, can the safety guarantee axle lift by crane perpendicularly, avoids the steel sheet direct and axle rigid contact again through the protection of rubber blanket, can protect the axle, can not influence the precision of axle itself.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
