Description

A tensioning and locking device for a pulley of a crusher

technical field

The utility model relates to a pulley tensioning device, in particular to a tensioning and locking device for a pulley of a crusher.

Background technique

During the working process of the crusher, the vibration is relatively large, and the long-term use will change the position between the drive motor and the pulley, thereby reducing the tension of the pulley, and thus reducing the driving force transmitted from the drive motor to the crusher. So that the crushing efficiency of the crusher is reduced.

Therefore, during the installation process of the crusher, it is necessary to install the pulley tensioning device at the same time, but because the power required by the crusher is relatively large, the power of the driving motor is also relatively large, which makes the volume of the driving motor large. It is unrealistic to move. Considering the cost and operability, most of them use the cooperation between the screw and the nut to move the position of the drive motor. However, the screw is a rigid part. During the working process of the crusher, the screw is easy to drive the motor for a long time or vibrate too much. Large and broken, resulting in a sharp drop in pulley tension, resulting in stagnation of equipment and unnecessary losses for the enterprise.

Utility model content

The purpose of the utility model is to overcome the shortcomings of the prior art and provide a crusher pulley tensioning and locking device with simple structure, convenient operation and long service life.

The purpose of this utility model is achieved through the following technical solutions: a crusher pulley tensioning and locking device, which includes a drive motor, a base and a slideway, the drive motor is installed on the base, and the base is installed on the slide On the track, there are multiple slideways, and they are arranged side by side. One end of the base is provided with a bump corresponding to the slideway. A groove is opened on the bump, and an adjusting screw is hinged in the groove. A connecting block is arranged on the slideway, the adjusting screw passes through the connecting block and an adjusting nut is installed on the adjusting screw at both ends of the connecting block, and an elongated hole is provided on the described slideway, and the elongated hole is installed There is a locking bolt, the threaded end of the locking bolt passes through the projection and a locking nut is installed on the threaded end.

There are three slideways and they are parallel to each other.

One end of the adjusting screw is provided with a hinged part, and a through hole is provided in the hinged part, and a pin shaft is pierced in the through hole, and the two ends of the pin shaft pass through the corresponding groove side walls, and the two ends of the pin shaft are A limit pin is provided.

The utility model has the following advantages: the tensioning and locking device of the utility model is provided with an adjusting screw, and the adjusting screw is hingedly connected with the protrusion on the base, so that when the base vibrates, the adjusting screw always maintains the original position, and the adjustment screw will not be affected by the vibration of the base. The phenomenon of bending or breaking due to vibration will increase the service life of the device; there are locking bolts and locking nuts to further fix the position of the base, thereby ensuring the tension of the pulley and ensuring the broken The stability of the driving force of the machine ensures the production efficiency.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described, and the protection scope of the utility model is not limited to the following:

As shown in Figures 1 and 2, a crusher pulley tensioning and locking device includes a drive motor 1, a base 2 and a slideway 3, the drive motor 1 is installed on the base 2, and the base 2 Installed on the slideway 3, the slideway 3 is multiple, and arranged side by side, one end of the base 2 is provided with a bump 4 corresponding to the slideway 3, and a concave groove is provided on the bump 4 Groove 5, an adjusting screw rod 6 is hinged in the groove 5, a connecting block 7 is arranged on the described slideway 3, the described adjusting screw rod 6 passes through the connecting block 7 and is installed on the adjusting screw rod 6 at both ends of the connecting block 7 There is an adjusting nut 8, and an elongated hole 9 is provided on the slideway 3, and a locking bolt 10 is installed in the elongated hole 9, and the threaded end of the locking bolt 10 passes through the protrusion 4 and is threaded on its thread. A locking nut 11 is installed on the end.

In this embodiment, there are three slides 3 parallel to each other, and the three slides are respectively located at the two ends and the middle of the driving motor.

In this embodiment, as shown in Figure 3, one end of the adjusting screw 6 is provided with a hinged part 12, and a through hole is provided in the hinged part 12, and a pin shaft 13 is pierced in the through hole, and the pin shaft 13 is The two ends pass through the side walls of the corresponding groove 5, and both ends of the pin shaft 13 are provided with a limit pin 14. The vibration generated during the operation of the crusher will drive the drive motor 1 and the base 2 to vibrate, and the adjustment screw 6 is hingedly connected, so the projection 4 can rotate around the hinge 12, so that the adjusting screw 6 will not move, thus avoiding the bending or breaking of the adjusting screw caused by the vibration of the base 2.

The working process of the utility model is as follows: loosen the lock nut 11, move the adjusting nut 8 close to the base 2 to the direction close to the base, and then turn the adjusting nut 8 away from the base 2, so that the base 2 moves towards the connecting block 7, thereby driving The pulley on the motor is tensioned, then tighten the two adjustment nuts 8 to fix the position of the base 2 and the drive motor 1, and then tighten the lock nut to further fix the position of the base 2, so that the tensioned pulley The tension is stable, which ensures the driving force of the drive motor to the crusher.
