The stability of the stacker operation greatly affects the efficiency of filter rod transfer, and further affects the normal operation of the workshop.

[0003] The lifting mechanism is the core part of the stacker, including a lifting transmission mechanism and a guide rail. The lifting transmission mechanism and the guide rail are slidably connected to realize the up-down movement of the loading platform of the stacker.

At the same time, excessive wear of the column will cause the loading platform to tilt, affecting the operation efficiency of the equipment and posing a safety hazard. The guide rail is usually a one-time formed casting, and it is difficult to ensure its mechanical strength by using conventional repair methods such as surfacing and grinding. Therefore, it is difficult to maintain when the guide rail is worn.

[0036] As shown in Figures 1-6 The present embodiment provides a lifting mechanism, which comprises a carrying platform, a shell 100, a driving assembly, a guide rail 200 and a guide wheel assembly.

The output end of the driving member is in transmission connection with the walking wheel 300, so as to drive the walking wheel 300 to roll on the guide rail 200.

[0037] As shown in Figures 3-6 The guide wheel assembly comprises a roller 1, an axle 2, a bearing 3, a locking member 4 and an oil nozzle 5.

[0038] When the guide rail 200 is worn, the locking piece 4 is loosened, the locking between the eccentric section 21 and the shell 100 is cancelled, according to the actual wear of the guide rail 200, the eccentric section 21 is rotated to adjust the gap between the roller 1 and the guide rail 200, so that the roller 1 and the guide rail 200 are precisely matched, and after the adjustment is completed, the eccentric section 21 and the shell 100 are locked and fixed through the locking piece 4, so that the deviation of the guide precision caused by the wear of the guide rail 200 is corrected, the guide wheel and the guide rail 200 are kept in rolling cooperation, the guide rail 200 does not need to be surfacing polished, the maintenance time is greatly shortened, the stability of the lifting transmission mechanism operation can be ensured, the equipment operation efficiency is improved, the safety hidden danger is eliminated and reduced; The oil channel 24 is also provided in the wheel shaft 2, the inner ring of the bearing 3 is provided with a lubricating hole, the first end of the oil channel 24 penetrates the end face of the locking section 23 away from the mounting section 22, the second end penetrates the side face of the eccentric section 21, so as to communicate with the raceway of the bearing 3 through the lubricating hole, the oil nozzle 5 communicates with the first end of the oil channel 24, and the oil nozzle 5 can communicate with the external oil supply pipeline, so that the maintenance personnel can periodically lubricate the ball in the raceway of the bearing 3 without disassembling the lifting mechanism and the guide wheel assembly, the convenience and maintenance efficiency of the maintenance are improved, and the operation stability of the transmission mechanism and the service life of the guide wheel assembly are improved.

[0039] In order to conveniently adjust the position of the roller 1, the wheel shaft 2 further comprises an adjusting section 25, the adjusting section 25 is connected to one end of the eccentric section 21 away from the mounting section 22, and the adjusting section 25 is a prism type, so that the maintenance personnel can use tools to clamp or clamp the adjusting section 25, so that the eccentric section 21 rotates, thereby adjusting the gap between the roller 1 and the guide rail 200.

Alternatively, the adjusting section 25 includes but is not limited to a triangular prism, a dodecagonal prism or other shapes that are convenient for clamping or clamping, which is not limited herein

[0041] Further, the diameter of the circumscribed circle of the adjusting section 25 is greater than the diameter of the eccentric section 21, which can play an axial limiting role on the bearing 3 to prevent the bearing 3 from falling off.

[0042] In some optional embodiments, the height of the bearing 3 is equal to the length of the eccentric section 21, when the locking piece 4 locks the eccentric section 21 and the shell 100, the eccentric section 21 abuts against the surface of the shell 100, the bearing 3 is limited between the shell 100 and the adjusting section 25, avoiding the bearing 3 from moving, and the height of the roller 1 is less than the height of the bearing 3, avoiding the roller 1 on both sides from contacting the shell 100 and the adjusting piece, so that the roller 1 can rotate freely, thereby ensuring the stable and smooth operation of the lifting mechanism.

[0043] Further, the guide wheel assembly further comprises a positioning sleeve 6 sleeved on the mounting segment 22 and capable of being arranged in the positioning hole of the shell 100.

In addition, the height of the positioning sleeve 6 is equal to the length of the mounting segment 22. When the locking member 4 is locked, the two ends of the positioning sleeve 6 abut against the locking member 4 and the eccentric shaft respectively, thereby limiting the wheel shaft 2 in the axial direction.

[0044] Further, the hardness of the positioning sleeve 6 is lower than that of the shell 100 and the wheel shaft 2, capable of effectively preventing the wear of the shell 100 and the wheel shaft 2, improving the service life of the components, and facilitating the replacement of the positioning sleeve 6 and reducing the cost.

[0045] In the embodiment, the locking member 4 is a locking nut. The locking nut is in threaded connection with the locking segment 23.

The maximum outer diameter of the oil nozzle 5 is less than the inner diameter of the locking nut, avoiding the movement interference between the oil nozzle 5 and the locking nut, so that the locking nut can conveniently lock or unlock the wheel shaft 2 and the shell 100.

[0046] Specifically, the oil nozzle 5 is in threaded connection with the side wall of the oil channel 24, so that the oil nozzle 5 is stably connected with the wheel shaft 2, has good sealing performance, and is convenient to disassemble and clean and maintain. Alternatively, the oil nozzle 5 and the wheel shaft 2 include but are not limited to clamping or bonding, which is not limited herein.

[0047] Alternatively, the guide wheel assembly further comprises a gasket 7 clamped between the locking nut and the mounting segment 22, capable of increasing the contact area of the locking nut with the mounting segment 22 and the positioning sleeve 6, uniformly distributing the locking force, avoiding the surface damage of the mounting segment 22 due to local pressure concentration, ensuring the stable installation of the wheel shaft 2, preventing the loosening of the locking member 4 during operation, and further ensuring the operation stability of the lifting mechanism.

[0048] In other embodiments, the locking member 4 includes but is not limited to a snap ring or a locking pin, which is not limited herein.

[0049] As shown in Figure 1 and Figure 2 The lifting mechanism of the embodiment comprises at least two guide wheel assemblies arranged on the two sides of the guide rail 200. The two rollers 1 clamp the guide rail 200, capable of constraining the lifting mechanism from the opposite two directions, effectively preventing the dangerous situations such as shaking, deviation or even derailment of the lifting mechanism, ensuring the smooth and accurate operation of the lifting mechanism along the guide rail 200, greatly improving the reliability of the lifting operation of the roadway stacking machine, and ensuring the safety and stability of the filter rod transfer process.

[0050] The axes of the wheel shafts 2 of the two guide wheel assemblies are perpendicular to the axis of the walking wheel 300, and the two guide wheel assemblies are symmetrically arranged on both sides of the axis of the walking wheel 300, so that the side wall of the roller 1 is perpendicular to the side of the guide rail 200, and the side wall of the walking wheel 300 is perpendicular to the front of the guide rail 200, and the walking wheel 300 and the guide wheel assembly are reasonably arranged, which is beneficial to stabilize the force of the lifting mechanism.

[0051] In addition, the embodiment also provides a roadway stacker, which comprises a horizontal moving mechanism and the lifting mechanism of any one of the above embodiments, and the output end of the horizontal moving mechanism is in transmission connection with the guide rail 200, so as to drive the horizontal movement of the carrying platform through the guide rail 200, so that the roadway stacker can be efficiently operated in three-dimensional space.
