Description

Slave mode descending anti-slipping chain

Technical field

The utility model relates to a kind of safe anti-slipping chain device of descending unpowered type, a kind of specifically slave mode descending anti-slipping chain.

Background technology

Anti-slipping chain is the class conveyer in the conveyer system, generally be applied to the car production shop production line at the descending place, suspender pushes up at the end, slope from the slope under the drive of conduction chain, if conduction chain fracture this moment, then suspender will sweep away from eminence along track, all there is very big danger in safety to the person, equipment, therefore needs a kind of safety device that suspender safety can be stopped at the descending place of design.

It is with realization by the translator reductor that existing anti-slipping chain drives, this device can consume certain electric power and not satisfy current environmental protection requirement, motor reducer has the noise generation when operation simultaneously, and motor reducer also needs the expense of maintaining in use.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can satisfy suspender can stop suspender purpose after the conduction chain fracture suddenly when descending slave mode descending anti-slipping chain.

The technical scheme that provides according to the utility model, described slave mode descending anti-slipping chain, it is included in the rotating shaft that rotation is set up on the framework, in rotating shaft, be installed with drive sprocket, brake disc and driven sprocket, on framework, be installed with upper strata track and lower floor's track, be provided with chain in upper strata track and the lower floor's track, described chain and drive sprocket engagement, be installed with braking clamp on framework, described braking clamp cooperates with brake disc; Be installed with rotating speed coder on framework, be fixed with the coder sprocket wheel on the input shaft of rotating speed coder, coder sprocket wheel and driven sprocket are provided with the coder chain; Described rotating speed coder is connected with PLC, and PLC is connected with braking clamp, and the rotating shaft tach signal input PLC that rotating speed coder calculates handles, and the processing instruction input braking clamp of PLC is made cooresponding processing action by braking clamp.

Symmetric position in the rotating shaft both sides respectively is provided with a cover braking clamp.

The utility model can satisfy the requirement that suspender can stop suspender after the conduction chain fracture suddenly when descending, the utility model slave mode anti-slipping chain can reach purposes such as safety, environmental protection and energy saving, low noise and low maintenance expense after using.

Fig. 2 is a left view of the present utility model.

Fig. 3 is a birds-eye view of the present utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with concrete drawings and Examples.

As shown in the figure, the utility model is mainly by component set-ups such as braking clamp 1, framework 2, brake disc 3, upper strata track 4, lower floor's track 5, chain 6, drive sprocket 7, supporting bearing base 8, key 9, rotating shaft 10, driven sprocket 11, spacer 12, spacer 13, rotating speed coder 14, coder sprocket wheel 15, coder chain 16, key 17, spacer 18, outer cover 19 and fixed covers 20.

This slave mode descending anti-slipping chain, it is included in the rotating shaft 10 that rotation is set up on the framework 2, be useful on spacing spacer 12 in the rotating shaft 10, spacer 13 and spacer 18, the rotating shaft 10 whole supporting bearing base 8 of leaning on are installed on the framework 2, in rotating shaft 10, be installed with drive sprocket 7 by key 9, brake disc 3 and driven sprocket 11, brake disc 3 is fixed on the fixed cover 20, fixed cover 20 is fixed in the rotating shaft 10 by key 17, on framework 2, be installed with upper strata track 4 and lower floor's track 5, be provided with chain 6 in upper strata track 4 and the lower floor's track 5, described chain 6 and drive sprocket 7 engagements are installed with braking clamp 1 on framework 2, described braking clamp 1 cooperates with brake disc 3; Be installed with rotating speed coder 14 on framework 2, be fixed with coder sprocket wheel 15 on the input shaft of rotating speed coder 14, coder sprocket wheel 15 is provided with coder chain 16 with driven sprocket 11; Described rotating speed coder 14 is connected with PLC, and PLC is connected with braking clamp 1, and the rotating shaft tach signal input PLC that rotating speed coder 14 calculates handles, and the processing instruction input braking clamp 1 of PLC is made cooresponding processing action by braking clamp 1.

Symmetric position in rotating shaft 10 both sides respectively is provided with a cover braking clamp 1.

Working process of the present utility model is as follows:

Suspender promotes the allocated catch pawl on the chain 6 during normal operation according to the direction of arrow among Fig. 1 under the effect of conduction chain, chain 6 drives drive sprocket 7 and rotates together, drive sprocket 7 usefulness keys 9 are fixed in the rotating shaft 10, also fixing in the rotating shaft 10 have a fixed cover 20, brake disc 3, driven sprocket 11 parts such as grade, therefore all parts also follow drive sprocket 7 to rotate around bearing seat 8 together in the rotating shaft 10, driven sprocket 11 utilizes the transmission of coder chain 16 to drive coder sprocket wheel 15 again and rotating speed coder 14 input shafts rotate together, and rotating speed coder 14 calculates output speed.

After the conduction chain fracture of traction suspender, suspender can quicken to promote the pusher dog on the chain 6, the faster rotational speed of drive sprocket 7 and rotating shaft 10, this rotating speed can surpass the input speed of the setting of rotating speed coder 14, PLC gives the electromagnetic valve signal of control aerodynamic brake pincers 1, allow 1 pair of brake disc 3 of aerodynamic brake pincers make brake, effect lower rotary shaft 10 at this brake gear can stop operating, at this moment, chain 6 is also out of service, pusher dog on the chain 6 will make suspender stop, and finishes the seizure to suspender.
