Abstract
The utility model discloses a belt and chain automatic tensioning device, which includes a frame and a transmission device arranged on the frame, wherein the transmission device is a swinging bracket hinged with the frame and provided with a supporting platform; a retractable pull rod is connected between the frame and the swinging bracket and adopts a hydraulic oil cylinder and a hydraulic ejector rod controlled by the hydraulic oil cylinder; and a pressure switch is arranged on the hydraulic oil cylinder. The belt and chain automatic tensioning device has the advantages of conveniently adjusting a transmission belt to enable the transmission belt to be under optimum working state; a working motor can be fixed on the supporting platform of the swinging bracket, and the retractable pull rod connected between the frame and the swinging bracket can be adjusted, so as to enable the tightness degree of the belt to be under the optimum state and drive loading operation through the rotation of a belt pulley on a motor main shaft. When the belt is extended and slippage happens, for regulation of tightness degree of the belt, all that is needed is to adjust the retractable pull rod and change the angle of the swinging bracket by one person only. And the device can be used to regulate the automatic tensioning of the chain in a chain wheel/chain drive mechanism.
Description
Technical field
The utility model relates to mechanical field regulating device commonly used, especially relates to the used full-automatic belt of main equipment, chain stretching device.
Background technique
At mechanical field, motor normally drives load operation by drivign belt, can fluff, skid after belt uses certain hour, influence the equipment proper functioning, need in time belt to be adjusted, make it to keep tension, when belt damages, also need timely replacing.Adjustment belt or replacing belt not only bother, and also need many people to work together, the big and inefficiency of the amount of labour, if main equipment (as oil production equipment), it is more difficult that this work just seems.
The model utility content
The utility model purpose is to provide a kind of full-automatic belt that keeps belt to be in optimum Working, chain stretching device.
For achieving the above object, the utility model can be taked following technical proposals:
Full-automatic belt described in the utility model, chain stretching device, comprise support body and the transmission device that places on the described support body, described transmission device is the rocking carrier that has support platform that is hinged with described support body, is connected with telescopic lever between described support body and rocking carrier.
Described telescopic lever is a hydraulic jack and by the hydraulic mandril of its control action.
Described hydraulic jack is provided with pressure switch.
The utility model advantage is to adjust easily drivign belt and makes it to be in all the time optimum Working.During use, work drive motor is fixed on the support platform of rocking carrier, adjusts the telescopic lever that connects between support body and the rocking carrier, after making the belt elasticity remain on the optimum state, machine operation, the belt pulley on the electric machine main shaft rotates, and drives load operation by drivign belt.Behind belt work certain hour, belt is elongated, skidding appears, at this moment only need to adjust telescopic lever, change the angle of rocking carrier, can adjust the rate of tension of belt, whole adjustment work only needs a people to finish, saving manpower simple to operate has reduced working strength, has improved working efficiency.If belt damages, also only need to adjust telescopic lever, with the angle inclined in opposite directions of rocking carrier some, can very easily belt be loaded onto, very convenient and practical; This device also can be used for adjusting the auto-tensioning of sprocket wheel, chain drive chain.
If telescopic lever is set to hydraulic jack and by the hydraulic mandril of its control action, when needing to adjust, the primer fluid cylinder pressure is adjusted the angle of rocking carrier by stretching of hydraulic mandril, need not the manpower adjustment, convenient saving trouble.
Hydraulic jack is provided with pressure switch, can monitor the size of oil cylinder internal pressure, and control mechanism is adjusted the angle of rocking carrier by the monitoring driving oil cylinder work to the oil hydraulic cylinder internal pressure, makes belt keep optimum Working.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, full-automatic belt described in the utility model, chain stretching device, comprise support body 1 and the transmission device that places on the described support body 1, described transmission device is the rocking carrier that has support platform 23 that is hinged with described support body 1, between described support body 1 and rocking carrier 3, be connected with hydraulic jack 4 and by the hydraulic mandril 5 of its control action, described hydraulic jack 4 is provided with pressure switch 6.
During use, work drive motor 7 is fixed on the support platform 2 of rocking carrier 3 the primer fluid cylinder pressure, adjust the angle of rocking carrier 3 by stretching of hydraulic mandril 5, make the belt elasticity remain on the optimum state after, motor 7 work, belt pulley on the electric machine main shaft rotates, and drives load operation by drivign belt.Behind belt work certain hour, belt is elongated, skidding appears, at this moment only need to adjust the extrusion of hydraulic mandril 5, change the angle of rocking carrier 3, can adjust the rate of tension of belt, whole adjustment work only needs a people to finish, saving manpower simple to operate has reduced working strength, has improved working efficiency.If belt damages, also only need to adjust the collapsing length of hydraulic mandril 5, with the angle inclined in opposite directions of rocking carrier 3 some, can very easily belt be loaded onto, very convenient and practical; In like manner, this device also can be used for adjusting the auto-tensioning of sprocket wheel, chain drive chain.
Claims (3)
