Abstract
The invention discloses a lifting clamp used for an inner gear shaft of a gear-type coupling. The lifting clamp comprises a connection bolt, fastening screws and a connection ring provided with a notch. The end walls of the notch in the connection ring extend outwards to form platform-shaped connection lugs. The connection bolt is connected to the connection lugs in a penetrating mode. The fastening screws are in threaded connection with the peripheral wall of the connection ring, and the threaded ends of the fastening screws penetrate through the side wall of the connection ring. A connection buckle is arranged on the peripheral wall of the connection ring. The lifting clamp is simple in structure, convenient to use, firm in lifting and high in safety coefficient.
Description
Technical field:
The present invention relates to a kind of stone tongs for internal tooth axle in cog-wheel coupling.
Background technology:
In cog-wheel coupling, internal tooth axle in process of production, and normal needs drives a vehicle to its lifting, and mostly existing driving, when lifting internal tooth axle, being by tying up multiple tracks steel rope on the periphery of internal tooth axle, then being hung by this steel rope on the suspension hook be connected in driving.This kind of mode complex operation, and lift insecure, there is potential safety hazard.
Therefore, necessary the deficiency solving prior art is improved to prior art.
Summary of the invention:
The present invention provides a kind of stone tongs for internal tooth axle in cog-wheel coupling to solve above-mentioned prior art Problems existing.
The technical solution adopted in the present invention has: a kind of stone tongs for internal tooth axle in cog-wheel coupling, comprise tie bolt, tightening screw and establish coupling link jaggy, indentation, there end wall on described coupling link stretches out and forms the engaging lug of platform-like, tie bolt cross-under is on this engaging lug, described tightening screw is threaded on the outer circle wall of coupling link, and the thread end of tightening screw is through the sidewall of coupling link;
The outer circle wall of described coupling link is provided with junction button.
Further, the inner peripheral wall of described coupling link is provided with anti-slip rubber.
The present invention has following beneficial effect:
Structure of the present invention is simple, easy to use, and firmly, safety factor is high in lifting.
Accompanying drawing illustrates:
Fig. 1 is constructional drawing of the present invention.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1, a kind of stone tongs for internal tooth axle in cog-wheel coupling of the present invention, comprise tie bolt 2, tightening screw 3 and coupling link 1, coupling link 1 is provided with breach 4, on coupling link 1, the end wall at breach 4 place stretches out and forms the engaging lug 5 of platform-like, and tie bolt 2 cross-under is on this engaging lug 5, and tightening screw 3 is threaded on the outer circle wall of coupling link 1, and the thread end of tightening screw 3 is through the sidewall of coupling link 1, and stretch in the inner ring of coupling link 1.
Connect fixture of the present invention for ease of traveling crane, the outer circle wall of coupling link 1 is provided with junction button 6.
When lifting internal tooth axle in cog-wheel coupling, internal tooth axle being placed in the inner ring of coupling link 1, regulating tightening screw 3 according to the direct size of internal tooth axle, the internal tooth axle by lifting is anchored on coupling link 1.
The present invention increases the friction force between coupling link 1 and internal tooth axle, the inner peripheral wall of coupling link 1 is provided with anti-slip rubber 7, be installed on the inner peripheral wall of coupling link 1 for ease of anti-slip rubber 7, the inner peripheral wall of coupling link 1 is provided with some tapped bore, by screw, anti-slip rubber 7 is fixed on the inner peripheral wall of coupling link 1.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, can also make some improvement under the premise without departing from the principles of the invention, and these improvement also should be considered as protection scope of the present invention.
