Description

Technical Field

[0001] This utility model belongs to the field of stacker crane technology, specifically relating to a lifting mechanism on a stacker crane. Background Technology

[0002] Stacker cranes are a type of equipment used in warehouses, primarily for moving goods to their target locations and stacking them together to improve warehouse space utilization. The lifting mechanism is a key component of the stacker crane, used to lift goods from a low position to a high position, and then, in conjunction with the crane's horizontal moving parts, transports the goods to the target location.

[0003] However, the traditional stacker crane lifting mechanism, as seen in patent document CN102701117A, has a drive unit located in the middle, with wire rope winding structures on both sides. Due to load-bearing issues, the axial length of the winding structures on both sides is usually short. During lifting, if the wire rope loosens and is then tightened again, it can easily detach from its original slot and shift to another slot, causing the wire rope to become tangled or even fall off the winding structure, resulting in lifting failure. Therefore, a lifting mechanism for stacker cranes has been designed to solve the above problems.

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content

[0005] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a lifting mechanism for a stacker crane.

[0006] To achieve the above and other related objectives, the technical solution provided by this utility model is as follows: a lifting mechanism on a stacker crane, comprising: a mounting frame, wherein a first locking position and a second locking position are respectively provided on the left and right sides of the mounting frame; a winding drum, wherein the winding drum is disposed inside the mounting frame, and the surface of the winding drum is provided with a plurality of annular grooves for winding steel wire rope along the circumferential direction, wherein each annular groove is evenly distributed along the axial direction of the winding drum, and the groove width is adapted to the diameter of the steel wire rope; a rotating shaft, one end of which is connected to a driving device, the driving device being disposed on one side of the mounting frame, and the other end of which is fixedly connected to the winding drum, wherein the rotating shaft and the winding drum are coaxially arranged; and both ends of the rotating shaft are respectively locked in the first locking position and the second locking position.

[0007] Furthermore, a limiting shaft is provided on one side of the winding drum. The limiting shaft is fixed to the mounting bracket, and its axis is parallel to the axis of the winding drum. The axial length of the limiting shaft is greater than or equal to the axial length of the winding drum. In this design, the limiting shaft, positioned on one side of the winding drum, provides a certain degree of restraint on the wire rope, reducing the likelihood of the wire rope slipping out of the annular groove and becoming tangled due to changes in tension.

[0008] Furthermore, a rotatable limiting wheel is provided on the limiting shaft, and the limiting wheel is coaxially arranged with the limiting shaft. In this design, the limiting wheel can rotate and move with the wire rope when in contact, preventing the wire rope from directly contacting the limiting shaft, thus reducing contact friction and minimizing damage to the wire rope.

[0009] Furthermore, the distance between the limiting wheel and the winding drum is L, and the diameter of the wire rope is d, where L satisfies: d < L < 2d. In this design, the limiting wheel acts as a limiting and blocking mechanism for the wire rope, ensuring that the wire rope can be pulled smoothly while preventing it from detaching from its original groove and entering other grooves due to changes in tension.

[0010] Furthermore, the limiting wheel is located in the middle of the limiting shaft, and the axial length of the limiting wheel is greater than 4 / 5 of the axial length of the limiting shaft. In this design, the axial length of the limiting wheel ensures that it effectively limits most of the wire rope on the winding drum. The wire ropes on both sides typically have a fixed structure, making them less prone to misalignment.

[0011] Furthermore, the mounting bracket includes a base plate, a left side plate fixed to the left side of the base plate, a right side plate fixed to the right side of the base plate, and a rear baffle fixed to the rear side of the base plate; the first locking position and the second locking position are respectively opened on the left side plate and the right side plate, and the two ends of the limiting shaft are respectively fixed on the left side plate and the right side plate and located on the front side of the mounting bracket.

[0012] Furthermore, the bottom of both the first and second locking positions are arc-shaped. In this design, the arc-shaped structural design allows the rotating shaft to rotate more flexibly within the locking positions.

[0013] Furthermore, the mounting bracket also includes a side mounting seat, which is connected to a mounting plate via a mounting rod, and the drive device is fixed to the mounting plate. In this design, the mounting seat and related structures are used for mounting the drive device, which is detachably connected to the mounting plate via fasteners.

[0014] Furthermore, the winding drum has a hollow structure. In this design, the hollow winding drum structure is lighter, making it easier to suspend the entire mechanism.

[0015] Furthermore, the driving device is a speed reducer. In this design, the speed reducer, as the driving device, can reduce the rotational speed and increase the torque.

[0016] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0017] The lifting mechanism on the stacker designed in this utility model places the drive device on the side of the mounting frame, which allows the axial length of the winding part to be relatively longer. The design of setting a limiting structure on one side of the winding drum plays a certain limiting role for the wire rope, reducing the phenomenon of the wire rope coming out of the ring groove and causing mess due to changes in the tension of the wire rope, and ensuring the normal operation of the lifting mechanism.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0029] See appendix Figure 1 Appendix Figure 2 and attached Figure 3 As shown, this embodiment provides a lifting mechanism for a stacker crane, including:

[0030] Mounting frame 1 has a first locking position 101 and a second locking position 102 on its left and right sides respectively; mounting frame 1 also has several mounting holes for mounting with a stacker crane.

[0031] The winding drum 2 is located inside the mounting bracket 1. The surface of the winding drum 2 has several circumferential grooves 4 for winding the wire rope 3. (See attached diagram) Figure 4 As shown, the annular grooves 4 are evenly distributed along the axial direction of the winding drum 2, and the groove width of the annular grooves 4 is adapted to the diameter of the wire rope 3; the winding drum 2 has a hollow structure. The hollow winding drum 2 is lighter in weight, which facilitates the suspension of the entire mechanism.

[0032] A rotating shaft 5 is connected at one end to a drive device 6, which is located on one side of the mounting bracket 1. The other end of the rotating shaft 5 is fixedly connected to a winding drum 2, and the rotating shaft 5 and the winding drum 2 are coaxially arranged. Both ends of the rotating shaft 5 are respectively secured in a first locking position 101 and a second locking position 102. The bottom of both the first locking position 101 and the bottom of the second locking position 102 are arc-shaped. This arc-shaped structural design allows the rotating shaft 5 to rotate more flexibly within the locking positions. The drive device 6 is a speed reducer, which can reduce the rotational speed and increase the torque.

[0033] The drive unit 6 is placed on the side and a mounting bracket 1 is provided, so that the mounting bracket 1 can bear the tension of the wire rope 3 and share part of the load. Compared with the traditional structure, the axial length of the winding structure can be made relatively longer, reducing the possibility of the wire rope 3 falling off the winding structure.

[0034] See appendix Figure 1 and attached Figure 5 As shown, a limiting shaft 7 is provided on one side of the winding drum 2. The limiting shaft 7 is fixed on the mounting bracket 1, and its axis is parallel to the axis of the winding drum 2. The axial length of the limiting shaft 7 is greater than or equal to the axial length of the winding drum 2. The limiting shaft 7 stops on one side of the winding drum 2, which can play a certain limiting role for the wire rope 3, reducing the phenomenon that the wire rope 3 may come out of the annular groove 4 and cause tangling due to changes in tension. A rotatable limiting wheel 8 is provided on the limiting shaft 7, and the limiting wheel 8 is coaxially arranged with the limiting shaft 7. The limiting wheel 8 can rotate and can move with the wire rope 3 when in contact, so that the wire rope 3 will not directly contact the limiting shaft 7, reducing contact friction and minimizing damage to the wire rope 3.

[0035] The distance between the limiting wheel 8 and the winding drum 2 is L (actually the distance from the limiting wheel 8 to the bottom of the annular groove 4 of the winding drum 2), and the diameter of the wire rope 3 is d, where L satisfies: d < L < 2d. The limiting wheel 8 acts as a limiting and blocking mechanism for the wire rope 3, ensuring that the wire rope 3 can be pulled smoothly while preventing it from detaching from its original annular groove 4 and entering other annular grooves 4 due to changes in tension.

[0036] See appendix Figure 1 As shown, the limiting wheel 8 is located in the middle of the limiting shaft 7, and the axial length of the limiting wheel 8 is greater than 4 / 5 of the axial length of the limiting shaft 7. This ensures that the limiting wheel 8 can limit most of the wire rope 3. The portions of the wire rope 3 wound around the edges of the winding drum are usually not used and can be fixed to the winding drum 2 by locking blocks. The axial length of the limiting wheel 8 can be 9 / 10, 13 / 15, 14 / 15, etc., of the axial length of the limiting shaft 7.

[0037] See appendix Figure 5 As shown, the mounting bracket 1 includes a base plate 103, a left side plate 104 fixed to the left side of the base plate 103, a right side plate 105 fixed to the right side of the base plate 103, and a rear baffle 106 fixed to the rear side of the base plate 103. A first locking position 101 and a second locking position 102 are respectively formed on the left side plate 104 and the right side plate 105. The two ends of the limiting shaft 7 are respectively fixed to the left side plate 104 and the right side plate 105 and are located on the front side of the mounting bracket 1. The mounting bracket 1 also includes a side mounting seat 107, which is connected to a mounting plate 109 via a mounting rod 108. The drive device 6 is fixed to the mounting plate 109. The mounting rod 108 is fixedly connected to the mounting plate 109. The mounting seat 107 and related structures are used for the installation of the drive device 6. The drive device 6 is detachably connected to the mounting plate 109 via fasteners.

[0038] The lifting mechanism on the stacker designed in this utility model places the drive device on the side of the mounting frame, which allows the axial length of the winding part to be relatively longer. The design of setting a limiting structure on one side of the winding drum plays a certain limiting role for the wire rope, reducing the phenomenon of the wire rope coming out of the ring groove and causing mess due to changes in the tension of the wire rope, and ensuring the normal operation of the lifting mechanism.

[0039] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
