Detailed Description

The principles and features of the present utility model are described below with reference to the drawings, the illustrated embodiments are provided for illustration only and are not intended to limit the scope of the present utility model.

As shown in fig. 1, the telescopic conveyor deviation adjusting device of the embodiment comprises a cross beam 1 and carrier roller assemblies arranged on the cross beam 1, wherein each carrier roller assembly comprises a conical roller 2 and a slewing mechanism 6 connected to the lower end of the conical roller 2, and the two groups of carrier roller assemblies are symmetrically arranged and connected through a connecting rod mechanism 8. Specifically, the tapered roller 2 is fixedly connected with the slewing mechanism 6 through the bracket 3, preferably, a follower wheel 7 is further arranged at the lower end of the bracket 3, and the follower wheel 7 correspondingly slides when the tapered roller 2 swings around the slewing mechanism 6.

The link mechanism 8 comprises a swing arm 80 fixedly connected to the slewing mechanism 6 and a link 81 connected with the two swing arms 80, and the two tapered rollers 2 can swing synchronously under the action of the link mechanism 8. According to the utility model, a sliding block or a roller 800 is fixedly connected to the swing arm 80, an arc-shaped track 9 which is matched with the sliding block or the roller 800 and is arranged concentrically with the swing arm 80 is fixedly connected to the cross beam 1, and the arc-shaped track 9 is provided with a limiting structure for preventing the sliding block or the roller 800 from moving up and down.

In order to limit the swing amplitude of the swing rod and further limit the swing amplitude of the conical roller 2, limiting plates are arranged at two ends of the extending direction of the arc-shaped track 9 in the embodiment, and swing limiting mechanisms such as a baffle plate and a stop block arranged at other positions, such as the follower wheel 7 in the prior art, are omitted.

In this embodiment, an installation space is provided in the cross beam 1, the lower end of the swing mechanism 6 penetrates through the upper end surface of the cross beam 1 and extends into the installation space, correspondingly, the link mechanism 8 is disposed in the installation space, and the arc-shaped rail 9 is fixedly connected to the bottom wall corresponding to the installation space. Preferably, the lower end of the swing arm 80 is fixedly connected with a T-shaped slider, and correspondingly, the arc-shaped track 9 is a T-shaped groove, and the T-shaped slider is embedded in the T-shaped groove so that the swing arm 80 cannot move up and down.

In order to effectively attach the belt to the surface of the tapered roller 2, an effective deviation adjusting effect is further ensured, and in this embodiment, two ends of the tapered roller 2 are fixedly connected to the bracket 3 through a ball head structure 5 and a scissor type lifting frame 4 respectively. Further, the upper end of the scissor lift 4 is provided with a plugboard for inserting the shaft part of the conical roller 2, the upper end of the plugboard is also connected with a compression screw 40 in a threaded manner, when the height of the scissor lift 4 is adjusted, the shaft part of the conical roller 2 is correspondingly inclined, and the shaft part is compressed by adjusting the compression screw 40.

Since the diameters of both ends of the tapered roller 2 are different, the same angular velocity of the tapered roller 2 generates different linear velocities in the tapered diameter when the tapered roller 2 rotates. According to the relationship between the angular velocity and the linear velocity, the linear velocity is proportional to the radius in the case where the angular velocity is constant. Therefore, the linear velocity of the large end is large and the linear velocity of the small end is small in the tapered roller 2, and there is a linear velocity difference in one tapered roller 2. When the belt deviates, the belt contacts with the small end of the conical roller 2, and the conical roller 2 and the belt generate additional resistance due to the small linear speed, so that the slewing mechanism 6 is driven to rotate around the slewing shaft by a certain angle, and transverse thrust is applied to the belt, so that the belt after the deviation is promoted to return to the original position, the automatic deviation correction of the belt after the deviation is realized, and the centering operation of the belt is ensured.

In the automatic deflection adjusting process, the swing arm 80 swings stably along the arc-shaped track 9 and does not vibrate up and down, the sliding block or the roller 800 also plays a supporting role on the swing arm 80, the stable and smooth action of the connecting rod mechanism 8 is realized, the deformation is not easy, the rapid and accurate linkage of the two conical rollers 2 is ensured, and the effective automatic deflection adjusting is realized. The inclination angle of the conical roller 2 can be adjusted by adjusting the height of the scissor type lifting frame 4, so that the belt is more attached to the surface of the conical roller 2, and the deflection adjusting effect is improved.
