Description

Technical Field

[0001] The utility model relates to the technical field of stackers, in particular to a tunnel-type single-column stacker. Background Art

[0002] Column-type aisle stacker cranes are specially designed for high-bay warehouses. The height of warehouses using this type of crane has reached about 45 meters. The crane operates in the aisles between the shelves and is mainly used to transport unit cargo on pallets or in cargo boxes. It can also be driven to the corresponding cargo compartment, and the crew on board picks the cargo according to the requirements for delivery. The aisle stacker crane consists of a lifting mechanism, an operating mechanism, a cargo platform driver's cab and a frame. The lifting mechanism uses wire rope or chain lifting. The frame has one or two columns. The cargo platform rises and falls along the columns. The forks on the cargo platform can be extended to the cargo compartments on both sides of the aisle to store and retrieve items. The existing stacker storage and retrieval mechanism uses a three-stage linear differential telescopic fork, which consists of an upper fork, a middle fork, a lower fork and a guide needle bearing. However, these two types of traveling mechanisms are not easy to maintain and repair.

[0003] After searching, Chinese patent application No. 201810922828.0 discloses a rail-mounted aisle-type single-column stacker for three-dimensional shelves. This patent uses wire rope lifting to make the operation smooth, noiseless, and light in weight. Before the wire rope breaks, the outer wire breaks and becomes loose first, which is easy to find so that it can be replaced in time. Although the above patent has the effect of convenient replacement, it does not have an anti-fall function. Since the stacker is lifted by wire rope traction, the wire rope will wear after long-term use. Although it is checked regularly, it still breaks accidentally. If there is no anti-fall structure, the lifting platform will directly hit the ground, and the current stacker's lifting platform does not have a good shock absorption effect when it contacts the ground. Therefore, it is necessary to design an aisle-type single-column stacker. Utility Model Content

[0004] The main purpose of the utility model is to provide a tunnel-type single-column stacker, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A lane-type single-column stacker comprises an electric guide rail, the upper surface of the electric guide rail is slidably connected to a base plate, an electric winch is installed on one side of the upper surface of the base plate, a steel wire rope is provided on the outer surface of the electric winch, one end of the steel wire rope is fixedly connected to a lifting platform, the upper surface of the base plate is fixedly connected to a vertical plate, and the outer surface of the vertical plate is fixedly connected to an anti-fall hook on the side close to the lifting platform; one side of the upper surface of the lifting platform is rotatably connected to a rotating shaft, the outer surface of the rotating shaft is fixedly connected to an L-shaped plate, one end of the L-shaped plate is fixedly connected to a hook, and the other end of the L-shaped plate is fixedly connected to a cross bar, one end of the rotating shaft is fixedly connected to a torsion spring, and the torsion spring is clamped with the lifting platform.

[0007] In order to achieve a sliding effect, as an aisle-type single-column stacker of the present invention, one side of the lifting platform is fixedly connected to a mounting seat, and one side of the mounting seat is rotatably connected to a pulley.

[0008] In order to facilitate up and down sliding, as an aisle type single-column stacker of the present invention, a slide groove is opened on one side of the vertical plate, and the slide groove is slidably connected to the pulley.

[0009] In order to provide a supporting function, as an aisle-type single-column stacker of the present invention, one side of the lifting platform is fixedly connected with a support plate, and the number of the support plates is two.

[0010] In order to produce a damping effect, as an aisle-type single-column stacker of the present invention, a damping rod is fixedly connected to the lower surface of the lifting platform, and a second spring is sleeved on the outer surface of the damping rod.

[0011] In order to achieve a better buffering effect, as an aisle-type single-column stacker of the utility model, the bottom end of the damping rod is fixedly connected to a rubber pad.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In the utility model, through the arrangement of the anti-fall hook, L-shaped plate, hook and cross bar, during use, the L-shaped plate has a rotation effect through the rotating shaft. After rotation, the wire rope is passed through the hook, and the wire rope is tightened by the gravity effect of the lifting platform to prevent the L-shaped plate from rotating. At this time, the torsion spring is deformed by the acting force. After the goods are placed on the lifting platform, the electric winch is started to drive the wire rope to raise the lifting platform for stacking goods. After the contact end of the wire rope and the lifting platform is accidentally broken, the hook is released and the torsion spring rebounds to drive the L-shaped plate to flip toward the anti-fall hook, so that after the cross bar rotates and is stuck inside the anti-fall hook, it can prevent the lifting platform from falling directly, thereby having an anti-fall effect.

[0014] 2. In the utility model, through the setting of the damping rod, spring and rubber pad, during use, when the lifting platform drops to the lowest point, the rubber pad contacts the bottom plate to produce a certain buffering effect. At the same time, the damping rod is compressed after being subjected to the force, and the damping effect is produced through the internal special damping oil, which can avoid excessive vibration after the lifting platform drops. The spring is deformed by pressure and rebounds, so that the damping rod is reset, which greatly increases the shock absorption effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In this embodiment, one side of the upper surface of the lifting platform 5 is rotatably connected to a rotating shaft, the outer surface of the rotating shaft is fixedly connected to an L-shaped plate 7, one end of the L-shaped plate 7 is fixedly connected to a hook 8, the other end of the L-shaped plate 7 is fixedly connected to a cross bar 9, and one end of the rotating shaft is fixedly connected to a torsion spring 10, which is clamped with the lifting platform 5.

[0024] During specific use, the L-shaped plate 7 has a rotating effect through the rotating shaft. After rotation, the wire rope 4 is passed through the hook 8. The wire rope 4 is in a taut state due to the gravity effect of the lifting platform 5 to prevent the L-shaped plate 7 from rotating. At this time, the torsion spring 10 is deformed by the acting force. After the goods are placed on the lifting platform 5, the electric winch is started to drive the wire rope 4 to lift the lifting platform 5 for stacking goods. After the contact end of the wire rope 4 and the lifting platform 5 is accidentally broken, the hook 8 is released and the torsion spring 10 rebounds, driving the L-shaped plate 7 to flip toward the anti-fall hook 6, so that the cross bar 9 rotates and is stuck inside the anti-fall hook 6, which can prevent the lifting platform 5 from falling directly.

[0025] In this embodiment, a mounting seat 11 is fixedly connected to one side of the lifting platform 5 , and a pulley 12 is rotatably connected to one side of the mounting seat 11 .

[0026] During specific use, the mounting base 11 is utilized to fix the pulley 12 , and the pulley 12 has a rotation effect, making the up and down sliding more stable.

[0027] In this embodiment, a sliding groove 13 is formed on one side of the vertical plate 3 , and the sliding groove 13 is slidably connected to the pulley 12 .

[0028] During specific use, the pulley 12 has a sliding effect in the slide groove 13, so that the mounting seat 11 drives the lifting platform 5 to move up and down.

[0029] In this embodiment, one side of the lifting platform 5 is fixedly connected with a support plate 14 , and the number of the support plates 14 is two.

[0030] When in use, after placing goods on the support plate 14 , it has a supporting effect, making it easy to store and stack goods.

[0031] In this embodiment, a damping rod 16 is fixedly connected to the lower surface of the lifting platform 5 , and a second spring 17 is sleeved on the outer surface of the damping rod 16 .

[0032] During specific use, the damping rod 16 is compressed after being subjected to an action force, and a damping effect is generated through internal structures such as the special damping oil, thereby increasing the shock absorption effect.

[0033] In this embodiment, a rubber pad 18 is fixedly connected to the bottom end of the damping rod 16 .

[0034] During specific use, when the lifting platform 5 descends to the lowest point, the rubber pad 18 contacts the bottom plate 2 to produce a certain buffering effect.

[0035] Working principle: During use, the L-shaped plate 7 is rotated by the rotating shaft. After the rotation, the wire rope 4 is passed through the hook 8. The gravity effect of the lifting platform 5 makes the wire rope 4 taut to prevent the L-shaped plate 7 from rotating. At this time, the torsion spring 10 is deformed by the force. After the goods are placed on the lifting platform 5, the electric winch is started to drive the wire rope 4 to raise the lifting platform 5 for stacking goods. The sliding effect of the bottom plate 2 and the electric guide rail 1 is used to facilitate lateral movement. After the contact end of the wire rope 4 and the lifting platform 5 is accidentally broken, the hook 8 is released through the torque The rebound effect of the spring 10 drives the L-shaped plate 7 to flip toward the anti-fall hook 6, so that the cross bar 9 rotates and is stuck inside the anti-fall hook 6, which can prevent the lifting platform 5 from falling directly, thereby having an anti-fall effect. When the lifting platform 5 drops to the lowest point, the rubber pad 18 contacts the bottom plate 2 to produce a certain buffering effect. At the same time, the damping rod 16 is compressed after being subjected to the force, and a damping effect is generated through the internal unique damping oil, which can prevent the vibration amplitude of the lifting platform 5 from being too large after it drops. The second spring 17 rebounds after being deformed by pressure, causing the damping rod 16 to reset, greatly increasing the shock absorption effect.
