The working principle of the deviation adjustment device for the sintering trolley provided by the embodiment of the present utility model is described below:

When in use, two sintering trolley deviation adjustment devices are installed on both sides of the head and tail star wheels of the sintering machine. After the trolley enters the star wheel at the head or the tail, the two sintering trolley deviation adjustment devices are located on both sides of the trolley. Align the trolley. The following takes a sintering trolley deviation adjustment device as an example to describe its working process: the support frame 1 is used as the installation basis, the control nut 3 on one side (ie, the outer side) is used to cooperate with the lead screw 4 to realize the driving function, and the other The accommodating groove 2 on one side (ie, the inner side) supports and limits the pushing member 5 . The lead screw 4 and the control nut 3 are threadedly connected. During the rotation of the lead screw 4, translation occurs, which drives the pusher 5 to translate in the accommodating groove 2. After the pusher 5 moves to contact with the trolley, continue to rotate the lead screw to push the The trolley moves to adjust the position of the trolley.

It can be seen that, with the device for adjusting the deviation of the sintering trolley provided by the embodiment of the present invention, the trolley can be pushed to move by rotating the screw 4 to complete the alignment work of the trolley, so as to avoid the phenomenon of the trolley gnawing on the rails. And the structure is simple, the operation is convenient, and the reliability is strong. In addition, the adjustment position takes place in the star wheels at the head and tail ends of the sintering machine, and the trolley can be adjusted without stopping the sintering machine, thereby improving production efficiency and economic benefits.

Optionally, in the embodiment of the present invention, in order to facilitate the rotation of the lead screw 4 , one end of the lead screw 4 is provided with a square head 6 . This arrangement facilitates the rotation of the lead screw 4 by clamping the square head 6 at the end of the lead screw 4 with a wrench, thereby reducing the difficulty of operation.

Optionally, a locking nut 7 is sleeved on the lead screw 4 on one side of the control nut 3 in a threaded connection manner. When adjusting the lead screw 4, first keep the lead screw 4 still, and rotate the lock nut 7 outward to keep the lock nut 7 away from the control nut 3 to reserve the adjustment stroke. Then turn the lead screw 4 to perform the offset adjustment and alignment work. After the adjustment is completed, keep the lead screw 4 rotating, and rotate the locking nut 7 inward until the locking nut 7 is in close contact with the control nut 3. At this time, the lead screw 4 cannot be rotated further inward. By setting the locking nut 7 to limit the lead screw 4, it is ensured that the lead screw 4 will not move further inward after the adjustment is completed, thereby ensuring the safety and stability of use.

In the embodiment of the present invention, the accommodating groove 2 supports and accommodates the pushing member 5 on the one hand, and can also limit the offset of the accommodating member on the other hand. Based on the function of the accommodating groove 2, as shown in Fig. 2 and Fig. 3, the accommodating groove 2 can be a U-shaped groove, and the pusher 5 is blocked by the side wall of the U-shaped groove in the U-shaped groove with only one degree of freedom to avoid the occurrence of skewed. Further, the outer wall of the U-shaped groove can also be provided with reinforcing ribs 8 to improve the strength.

The structure of the reinforcing rib 8 can be seen in FIG. 2 and FIG. 3 , and the reinforcing rib 8 is arranged in a triangular structure with strong stability. For example, the number of reinforcing ribs 8 is four, and two reinforcing ribs 8 are respectively provided on the two side walls of the accommodating groove 2 .

Wherein, the accommodating groove 2 and the control nut 3 may be respectively fixed on both sides of the support frame 1 by welding, or other fixing methods may be used, which will not be repeated in the embodiments of the present invention.

In the implementation of the present invention, the pusher 5 is in direct contact with the trolley under the drive of the lead screw 4 to push the trolley to move. The structure of the pusher 5 is illustrated below.

As an example, as shown in FIG. 1 , the pusher 5 includes: a support 51 and an adjustment wheel 52 , the support 51 includes a base and two opposite side plates vertically connected to the base; the adjustment wheel 52 passes through a pin shaft 53 is connected between the two side plates. The lead screw 4 is connected with the support 51 to push the support 51 to move in the accommodating groove 2, and the adjusting wheel 52 contacts the trolley to push the trolley. The adjustment wheel 52 is rotatably connected to the support 51 through the pin shaft 53. After the trolley is adjusted and aligned, when the trolley drives out of the star wheel, there is rolling friction between the adjustment wheel 52 and the trolley. On the basis of maintaining the limit effect, there will be no large frictional force hindering the movement of the trolley.

Wherein, as shown in Figures 1 and 3, the side plate includes a rectangular plate segment and a trapezoidal plate segment, and a support plate is also provided at the junction of the rectangular plate segment and the trapezoidal plate segment, and the rectangular plate segments of the two side plates , base and support plate enclose a cubic structure. A pin 53 is connected between the trapezoidal plate segments of the two side plates.

In the embodiment of the present invention, the lead screw 4 is translated during the rotation process, and the support 51 only needs to be translated. Based on this, the lead screw 4 and the support 51 can be connected in the following way: a control system is provided on the base. The plate 9, the other end of the lead screw 4 is provided with a disc, and the disc is rotatably limited in the control plate 9. In this way, the rotation of the disk does not drive the support 51 to rotate, and the disk drives the screw 4 to translate when the disk moves in translation with the screw 4 , converting the rotation and translation of the screw 4 into the translation of the support 51 .

Optionally, as shown in FIG. 1 , a clamping plate 54 is provided between the pin shaft 53 and the side plate to limit the rotation of the pin shaft 53 .

In order to facilitate the rotation of the adjustment wheel 52 , a bearing is provided between the adjustment wheel 52 and the pin shaft 53 .

In the embodiment of the present invention, in order to ensure the adjustment accuracy, the adjustment wheel 52 is a rigid wheel sleeve to avoid elastic deformation.
