Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and specifically to a lifting drum. Background Technology

[0002] In portable machinery, there are many types of lifting mechanisms. In actual use, different lifting mechanisms are generally selected based on the different operating conditions of the equipment. For example, the lifting mechanism commonly used in existing stacker cranes is a lifting drum with a steel wire rope to raise and lower the equipment. However, in existing lifting mechanisms that drive the drum to rotate and wind up the steel cable, the steel wire rope on the lifting drum is mostly fixed directly to the drum or the drum's side plate via a pressure plate. This presents the following problems in actual use: fixing the steel wire rope to the drum increases the drum length, thereby increasing the stacker crane's operating width, which in turn requires increasing the width of the rack aisles. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a lifting drum.

[0004] The lifting drum of this utility model includes:

[0005] The cylinder body has one side connected to the output shaft of the lifting motor by bolts. The side of the cylinder body used to install the starting end of the lifting steel cable is set as the installation end. The edge of the cylinder body near the installation end has a cable hole.

[0006] The mounting end of the cylinder is open, and at least one fixing plate for installing steel cables is installed on the inner wall of the cylinder.

[0007] In some embodiments, a plurality of reinforcing ribs are mounted around the interior of the cylinder along the internal gap of the cylinder, and there are installation intervals between the reinforcing ribs. The outer side of the fixing plate protrudes or is parallel to the outer end of the reinforcing ribs.

[0008] In some embodiments, the cable hole is located between the mounting intervals of the two reinforcing ribs;

[0009] Furthermore, the fixed pressure plate is mirror-symmetrical about the diameter of the cylinder where the rope hole is located.

[0010] In some embodiments, when the number of reinforcing ribs is even, the number of fixing plates corresponds one-to-one with the number of reinforcing ribs.

[0011] In some embodiments, when the number of reinforcing ribs is odd, the number of fixing plates is one more than the number of reinforcing ribs;

[0012] The rope hole is located at a position on the cylinder corresponding to a reinforcing rib, and a fixing pressure plate is installed on both sides of the reinforcing rib corresponding to the rope hole.

[0013] In some embodiments, the fixing plate is welded and installed between one side of the reinforcing rib and the inner wall of the cylinder.

[0014] In some embodiments, an installation cavity for accommodating steel cables is provided between the outer side of the fixed pressure plate and the outer end of the cylinder.

[0015] In some embodiments, the mounting plate is also provided with a number of fixed pressure plates that are adapted to the number of fixed pressure plates. Both the mounting plate and the fixed pressure plate are provided with threaded holes. The mounting plate is mounted on the fixed pressure plate by bolts passing through the threaded holes.

[0016] In some embodiments, the mounting plate has two limiting grooves adapted to the lifting cable symmetrically opened along the threaded hole on the side near the fixed plate.

[0017] In some embodiments, limiting plates for limiting the steel wire are installed at both ends of the cylinder.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. This utility model, by opening a rope hole on the installation end of the cylinder, and cooperating with the fixed pressure plate inside the cylinder, as well as the installation cavity between the fixed pressure plate and the cylinder, can effectively install the beginning of the lifting steel cable inside the cylinder by installing the pressure plate and the fixed pressure plate, thereby effectively reducing the length of the cylinder. When used on a stacker crane, it can minimize the width of the rack aisle.

[0020] 2. In this utility model, the fixing pressure plate is symmetrically arranged inside the cylinder along the diameter of the rope hole. Regardless of whether the rope groove on the cylinder is left-handed or right-handed, the fixing pressure plate is in the same position inside the cylinder, thus providing good force bearing. Moreover, there is no need to distinguish the direction of the fixing pressure plate according to the rope groove of the left and right cylinders, which facilitates the processing and installation of the equipment.

[0030] Example 1:

[0031] Please see Figures 1-4 The lifting drum of this utility model includes:

[0032] The cylinder 1 has one side connected to the output shaft of the lifting motor 13 by bolts. The side of the cylinder 1 used to install the starting end of the lifting steel cable 12 is set as the installation end 6. The edge of the cylinder 1 near the installation end 6 is provided with a cable hole 2.

[0033] The mounting end 6 of the cylinder 1 is open, and at least one fixing plate 3 for installing steel cables is installed on the inner wall of the cylinder 1.

[0034] Several reinforcing ribs 4 are installed around the inside of the cylinder 1 along the internal gap of the cylinder 1. There are installation intervals 5 between the reinforcing ribs 4. The outer side of the fixing plate 3 protrudes or is parallel to the outer end of the reinforcing ribs 4.

[0035] The cable hole 2 is located between the installation intervals 5 of the two reinforcing ribs 4;

[0036] Furthermore, the fixed pressure plate 3 is mirror-symmetrical about the diameter of the cylinder 1 where the rope hole 2 is located.

[0037] When the number of reinforcing ribs 4 is even, the number of fixing plates 3 corresponds one-to-one with the number of reinforcing ribs 4.

[0038] It also includes mounting plates 9 that are matched with the number of fixed pressure plates 3. Both the mounting plates 9 and the fixed pressure plates 3 have threaded holes 8. The mounting plates 9 are installed on the fixed pressure plates 3 by bolts passing through the threaded holes 8. The mounting plates 9 have two limiting grooves 10 that are matched with the lifting steel cables 12 symmetrically opened along the threaded holes 8 on the side of the mounting plates 9 near the fixed pressure plates 3.

[0039] Both ends of the cylinder 1 are equipped with limiting plates 7 for limiting the steel wire.

[0040] Working principle:

[0041] The beginning end of the lifting steel cable 12 is inserted into the inside of the cylinder 1 through the rope hole 2 on the cylinder 1. Then, according to the direction of the rope groove on the cylinder 1, the lifting steel cable 12 is installed on the fixed pressure plate 3 corresponding to the rope hole 2 through the mounting pressure plate 9 and bolts. Then, the lifting steel cable 12 is connected to the fixed pressure plate 3 in sequence through the mounting pressure plate 9.

[0042] Since the fixed pressure plate 3 is symmetrically arranged inside the cylinder 1 along the diameter of the rope hole 2, the fixed pressure plate 3 is in the same position on the side of the cylinder 1 regardless of whether the rope groove on the cylinder 1 is left-handed or right-handed. Therefore, it has good force bearing capacity and does not need to be distinguished according to the rope groove of the left and right cylinders 1 to distinguish the direction of the fixed pressure plate 3, which facilitates the processing and installation of the equipment.

[0043] Example 2:

[0044] Please see Figure 5 As a variation of Embodiment 1, when the number of reinforcing ribs 4 is odd, the number of fixing plates 3 is one more than the number of reinforcing ribs 4.

[0045] The rope hole 2 is located at the position of the reinforcing rib 4 on the cylinder 1, and the reinforcing rib 4 corresponding to the rope hole 2 is equipped with a fixing pressure plate 3 on both sides.

[0046] Working principle:

[0047] When processing and welding the fixed pressure plate 3, the fixed pressure plate 3 is installed on both sides of the reinforcing rib plate 4 corresponding to the rope hole 2. In actual use, it also has the advantage of not needing to distinguish the direction of the fixed pressure plate 3 according to the rope groove of the left and right cylinders 1, which facilitates the processing and installation of the equipment.

[0048] In Embodiment 1 and Embodiment 2, the fixing plate 3 is welded and installed between one side of the reinforcing rib plate 4 and the inner wall of the cylinder 1, so that the fixing plate 3 can serve as a base for installing the lifting steel cable 12, and can also further strengthen the reinforcing rib plate 4.

[0049] In both Embodiment 1 and Embodiment 2, an installation cavity 11 for accommodating the steel cable is provided between the outer side of the fixed pressure plate 3 and the outer end of the cylinder 1; thereby effectively ensuring that the installation of the lifting steel cable 12 does not affect the actual length of the cylinder 1.

[0050] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
