[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a technical solution for the horizontal track wheel of a stacker crane.

[0026] Please see Figure 1 and Figure 2 The system includes a mounting plate 1, on the outer surface of which a buffer connecting plate 10 is fixedly mounted. The buffer connecting plate 10 is used to connect a buffer. The mounting plate 1 is fixedly connected to the main body of the stacker crane to ensure that the device enables the stacker crane to run smoothly along a predetermined track. The buffer connected to the buffer connecting plate 10 can absorb the impact force received by the stacker crane through the buffer connecting plate 10, thereby protecting the safety of the equipment and goods. The structural structures of each component shown in the accompanying drawings of this application are all exemplary illustrations. The specific implementation should be adapted and optimized according to the functional requirements, assembly conditions and process limitations in the actual application scenario, including adjustments to the structural parameters, dimensions and connection methods.

[0027] The mounting plate 1 has two adjustable base plates 2 on its exterior. The interior of the adjustable base plate 2 has a set of fixed elongated holes 6, and each fixed elongated hole 6 is fitted with a fastening bolt 9. The end of each fastening bolt 9 is threaded to the mounting plate 1. The operator can pass the fastening bolt 9 through the fixed elongated hole 6 and thread it into the threaded hole on the mounting plate 1 to fix the adjustable base plate 2. The adjustable base plate 2 provides support and fixation for the use of the guide wheel assembly 3. The fixed elongated holes 6 and fastening bolts 9 facilitate the adjustment of the installation position of the adjustable base plate 2, enhance the adjustability of the device, and enable the device to adjust its installation position according to the requirements of the guide wheel's movement stroke, thereby improving the practicality of the device.

[0028] Each adjusting base plate 2 is equipped with a guide wheel assembly 3 on its exterior. A mounting plate 4 is fixedly connected to the outer surface of the adjusting base plate 2. A bearing 5 is rotatably installed inside the guide wheel assembly 3. The mounting plate 4 and the bearing 5 are compatible. The guide wheel assembly 3 can guide, transmit force, and ensure stable operation, enabling the stacker crane to operate smoothly and improving the stability of the stacker crane in handling goods. The installation of the mounting plate 4 and the bearing 5 facilitates the rotation of the guide wheel assembly 3 outside the adjusting base plate 2 and provides convenience for subsequent disassembly and replacement of the guide wheel assembly 3. The mounting plate 4 and the bearing 5 should avoid being connected by threads as much as possible, because during the rotation of the guide wheel assembly 3, there is a certain friction between it and the overhead rail. This friction can cause the threads between the mounting plate 4 and the bearing 5 to loosen, thereby affecting the safety of the stacker crane.

[0029] The end of the mounting plate 1 is threaded with a limit bolt 7. The end of the limit bolt 7 is rotatably connected to the adjusting base plate 2. The operator can adjust the travel of the stacker crane by rotating the limit bolt 7. That is, the rotation of the limit bolt 7 can push the adjusting base plate 2 to move outside the mounting plate 1, thereby changing the circumference of the guide wheel's outline and thus changing the travel trajectory of the guide wheel. This enables precise control of the stacker crane's running trajectory and significantly improves its applicability.

[0030] Please see Figure 3 and Figure 4 The mounting plate 4 is equipped with a fixing mechanism 8, which includes a turntable 801 and a rotating rod 802 that rotate inside the mounting plate 4. The turntable 801 and the rotating rod 802 are adapted to each other. A worm gear is installed on the outer surface of the turntable 801, and a worm is installed on the outer surface of the rotating rod 802. When the rotating rod 802 rotates, it can drive the turntable 801 to rotate inside the mounting plate 4 through the meshing relationship between the worm and the worm gear, so that the mounting plate 4 can stably clamp the bearing 5 and provide stable support for the installation and use of the guide wheel assembly 3.

[0031] The mounting plate 4 has a set of limiting grooves 803 inside, and each limiting groove 803 has a limiting rod 804 slidably connected inside. The end of the bearing 5 has a set of insertion holes, and each limiting rod 804 is inserted into the corresponding insertion hole. The limiting groove 803 is a straight groove, and the driving groove 806 is a curved groove with a certain arc. When the turntable 801 rotates, it can drive the limiting rod 804 to move through the limiting groove 803 and the driving groove 806, so that the limiting rod 804 can be inserted into the insertion hole at the end of the bearing 5 to fix the bearing 5, or the limiting rod 804 can be disengaged from the bearing 5 to facilitate the removal of the bearing 5 from the mounting plate 4 for replacement of the guide wheel assembly 3.

[0032] Each limiting rod 804 has a transmission slide rod 805 fixedly connected to its outer surface. The turntable 801 has a set of drive grooves 806 inside. The transmission slide rod 805 slides inside the drive grooves 806. When the turntable 801 rotates, the drive grooves 806 also rotate. The rotation of the drive grooves 806 can drive the transmission slide rod 805 to move. When the transmission slide rod 805 and the limiting rod 804 move, they are restricted by the limiting grooves 803, so that the rotation of the turntable 801 can drive the limiting rod 804 to slide inside the limiting grooves 803.

[0033] The mounting plate 4 is internally fixedly connected to a fastening sleeve 807. The end of the fastening sleeve 807 has a special design, namely, the outer surface of the end of the fastening sleeve 807 has a certain angled bevel, and the inner wall has a meshing tooth with a high coefficient of friction. The corresponding position of the rotating rod 802 is provided with a meshing ring that matches the meshing tooth. When the fastening sleeve 807 clamps the rotating rod 802 under the action of the pressing nut 808, it can prevent the rotating rod 802 from rotating inside the mounting plate 4 due to external vibration or other factors through the friction and pressure between the teeth and the ring.

[0034] The rotating rod 802 passes through the fastening sleeve 807 and is rotatably connected to the fastening sleeve 807. The outer surface of the mounting plate 4 is threaded with a pressure nut 808, which is adapted to the fastening sleeve 807. The inner wall of the end of the pressure nut 808 has an inclined sliding surface adapted to the end of the fastening sleeve 807. When the pressure nut 808 is tightened into the mounting plate 4, the inner wall of the pressure nut 808 will squeeze the fastening sleeve 807, thereby causing the end of the fastening sleeve 807 to deform to a certain extent under force, thus clamping and fixing the rotating rod 802 and preventing the rotating rod 802 from rotating and affecting the installation stability between the mounting plate 4 and the bearing 5.

[0035] Working principle: In use, the operator first places the adjusting base plate 2 on the surface of the mounting plate 1 and screws the fastening bolt 9 through the fixing elongated hole 6 onto the mounting plate 1. Then, the position of the adjusting base plate 2 is adjusted by rotating the limit bolt 7. After adjustment, the fastening bolt 9 is tightened. Then, the bearing 5 is aligned with the mounting plate 4 and inserted. Next, the pressure nut 808 is rotated. After the pressure nut 808 is rotated out of the mounting plate 4, the rotating rod 802 is rotated. The rotation of the rotating rod 802 can drive the turntable 801 to rotate through the meshing effect between the worm and the worm wheel. The rotation of turntable 801 can drive the limiting rod 804 to slide through the drive groove 806 and the limiting groove 803, thereby allowing the limiting rod 804 to be inserted into the insertion hole at the end of the bearing 5, thus completing the fixation of the bearing 5. Finally, the pressing nut 808 is tightened into the mounting plate 4. When the operator wants to replace the guide wheel assembly 3, he only needs to unscrew the pressing nut 808 from the mounting plate 4 and then rotate the rotating rod 802 to release the mounting plate 4 from fixing the bearing 5, which greatly improves the efficiency of the operator in replacing the guide wheel assembly 3.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
