Description
Technical Field
[0001] The utility model relates to the technical field of logistics warehousing, in particular to a drum pressure rope anti-falling mechanism. Background Art
[0002] The lifting and traction wire rope drum mechanism is widely used in logistics storage equipment and lifting equipment. Its function is to drive the drum to rotate through the rotation of the driving motor, so that the wire rope is wound on the drum along the rope groove to achieve the lifting or walking of the goods. However, the conventional drum mechanism has always had the problem that the wire rope is easily disordered when the rope is loose, and it is easy to slip out of the rope groove or even from the drum. After slipping out, when the wire rope is tightened again, a malfunction occurs, which can cause secondary damage to the equipment in serious cases.
[0003] To solve the above problems, the conventional method is to wrap three round rods with polyurethane tubes and clamp them between the motor and the drum protection cover. This structure can prevent the wire rope from falling out of the groove when the rope is loose to a certain extent, but the three round rods are welded and fixed to the mounting plate and cannot be moved. They are easily damaged in the long-term friction with the wire rope, thereby reducing the effect and even eventually causing failure. There is also a method with only one block, which cannot completely restrain the wire rope and has a very poor protection effect. Summary of the invention
[0004] The utility model aims to design a drum rope pressure anti-slip mechanism to solve the problem of rope slipping out or how to avoid secondary damage to the equipment after the rope slips out, thereby improving the safety and stability of the equipment.
[0005] In order to achieve the above object, the technical solution of the utility model is:
[0006] A drum rope pressure anti-slip mechanism is arranged on both sides of the drum, and a protective cover is arranged on the outer side of the drum, which includes:
[0007] The first rope pressing assembly and the second rope pressing assembly are symmetrically arranged on both sides of the lower part of the drum, and the first rope pressing assembly and the second rope pressing assembly respectively include:
[0008] The left and right mounting plates are arc-shaped, respectively, and are arranged vertically and parallelly. The upper parts of the left and right mounting plates are bent and extended toward the winding drum to form a fixing part, and are connected by a first connecting shaft; the middle parts of the left and right mounting plates are connected by a second connecting shaft;
[0009] Two first nylon sleeves are respectively sleeved on two sides of the first connecting shaft;
[0010] A second nylon sleeve is sleeved on the middle part of the first connecting shaft and between the two first nylon sleeves; a gap for adjustment is maintained between the first and second nylon sleeves;
[0011] The third rope pressing assembly is arranged at the bottom of the drum and located between the first and second rope pressing assemblies, and comprises:
[0012] The base is U-shaped, with shaft holes arranged on the upper part of both sides;
[0013] The mounting shaft has two pivots at both ends set in the shaft holes on both sides of the base;
[0014] Nylon tube, sleeved on the mounting shaft;
[0015] The first to third rope-pressing assemblies are assembled into a U shape, forming a structure for preventing the steel wire rope from falling off in three directions at the lower part of the drum.
[0016] Preferably, the outer surface of the drum is processed with a spiral guide groove for the wire rope, and at least three wire rope pressure blocks are provided, which are evenly spaced along the circumference of the outer surface of the drum and fixed to the drum by screws; the wire rope pressure block is provided with at least one arc-shaped groove corresponding to the spiral guide groove for the wire rope on a side surface corresponding to the outer surface of the drum.
[0017] Preferably, a rope outlet is provided on a side surface of the protective cover corresponding to one side of the first and second rope pressing components; one end opposite to the open end is aligned with the direction of the motor, and the other end surface adopts a transparent plate and is detachably connected to the protective cover.
[0018] Preferably, the gap between the first and second nylon sleeves, the nylon tube and the drum in the first, second and third rope-pressing assemblies is less than 40% of the diameter of the steel wire rope.
[0019] The advantages of the utility model are:
[0020] The utility model designs three rope-pressing components, which greatly reduces the possibility of the wire rope coming out of the rope groove of the drum due to loose rope and equipment jamming during the lifting process, and completely avoids the secondary damage such as the wire rope being drawn into the space between the drum and the motor flange after being loosened, thereby causing damage to the motor, thereby ensuring the safety of the equipment and improving the utilization rate of the equipment. The easily removable protective cover and acrylic observation window are arranged to facilitate timely detection of abnormalities and are easy to maintain in case of failure, so that equipment failure can be quickly handled and production can be resumed.
[0021] The utility model rope pressing assembly has a brand-new independent component design, which can facilitate the precise fine adjustment of the rope pressing gap. The nylon sleeve can be infinitely close to the wire rope pressing block, covering the width of the slot where the entire drum may be unhooked, and can better prevent the rope from being unhooked. The flexible free-rotating nylon sleeve can well prevent the wire rope from rubbing only on one side, which can minimize the damage rate of the gear parts and increase its service life.
