Abstract

The utility model discloses a non-return device for a lifter. The non-return device is characterized by comprising a ratchet and a pawl, wherein the ratchet is assembled on a driving shaft of the lifter in a non-rotation manner, and the pawl is rotatably assembled on a frame of the lifter and matched with the ratchet. A torsion spring is arranged on a rotation shaft of the pawl and the frame of the lifter, and the pawl contacts with the ratchet through the torsion spring. The ratchet is prevented from reversely rotating by the pawl, so that the driving shaft of the lifter is prevented from reversely rotating, a non-return purpose is achieved, a ratchet and pawl structure is reliable in operation, and the problems of jamming and start failure of the lifter are avoided.

Description

A kind of check device of gig
Technical field
The utility model relates to a kind of check device be used to the driving rotating shaft counter-rotating that prevents gig.
Background technology
In cement production process, raw material limestone need be risen in the calcination equipment, in the prior art, finish by gig, gig drives by the driving rotating shaft, drive rotating shaft and be provided with check device, check device prevents from driving the rotating shaft counter-rotating, guarantees that material can not fall in promoting, and the check device of available technology adopting is the roller check device, the roller intensity of roller check device is less, owing to burn till the load of the gig in the workshop, roller is easy to damage, in case roller damages, stuck phenomenon will appear in gig, causes gig to can't afford to drive.
The utility model content
The purpose of this utility model provides a kind of check device of gig, damages the problem that stuck phenomenon appears in gig easily that cause easily because of roller during with solution available technology adopting roller check device.
In order to realize above purpose, the utility model adopts following technical scheme: a kind of check device of gig, comprise for spline and be assemblied in the ratchet in the driving rotating shaft of gig and be used for rotating ratchet on the frame that is assemblied in gig, described ratchet cooperates with ratchet, and described ratchet is provided with the torsion spring that ratchet is contacted with ratchet with the rotating shaft of the frame of gig.
Described ratchet rotates by pedestal and is assemblied on the frame of gig, and ratchet rotates and is assemblied on the pedestal, and pedestal is used for being fixed on the frame of gig.
Check device of the present utility model comprises that spline is assemblied in the ratchet in the driving rotating shaft of gig, and the ratchet that cooperates with ratchet, prevent that by ratchet thereby the ratchet counter-rotating from preventing the axle drive shaft counter-rotating of gig, realize the non-return purpose, the click arrangement works is reliable, the problem that gig is stuck, can't afford to drive can not occur.
Description of drawings
Fig. 1 is the integral structure scheme drawing of the utility model embodiment.
The specific embodiment
A kind of embodiment of check device of gig, in Fig. 1, its ratchet 1 is used for the axle drive shaft that spline is assemblied in gig, and the ratchet 3 that cooperates with ratchet 1 rotates by rotating shaft 4 and is assemblied on the pedestal 5, and pedestal 5 is used for being fixed on the frame of gig.The rotating shaft 4 of ratchet 3 is provided with torsion spring, and this torsion spring makes ratchet 3 contact with the ratchet 2 of ratchet, makes ratchet 3 be pressed in forever on the ratchet 2, guarantees that pawl-and-gearing is in the state of cooperation.
In the present embodiment, guaranteeing that the structure that click is in mated condition is the torsion spring that is arranged in the rotating shaft 4, also can be extension spring, is arranged on extension spring between ratchet and the pedestal and makes extension spring be in a side near ratchet, one end of extension spring is fixed on the ratchet, and the other end is fixed on the pedestal.

Claims (2)

1. the check device of a gig, it is characterized in that: comprise for spline being assemblied in the ratchet in the driving rotating shaft of gig and being used for rotating ratchet on the frame that is assemblied in gig, described ratchet cooperates with ratchet, and described ratchet is provided with the torsion spring that ratchet is contacted with ratchet with the rotating shaft of the frame of gig.
2. the check device of gig according to claim 1 is characterized in that: described ratchet rotates by pedestal and is assemblied on the frame of gig, and ratchet rotates and is assemblied on the pedestal, and pedestal is used for being fixed on the frame of gig.
