Description

Technical Field

[0001] The utility model relates to the technical field of stackers, in particular to a stacking elevator with a safety protection mechanism. Background Technique

[0002] A stacker refers to a special crane that uses a forklift or a string rod to grab, transport, and stack or retrieve unit goods from a high-level shelf (see unitized transportation). It is a kind of warehousing equipment (see goods handling machinery), and is divided into a bridge-type stacker crane and a roadway stacker crane.

[0003] For example, the patent with the national authorized patent publication number CN213326564U discloses a stacker lifting mechanism, including a base, on the upper surfaces of both ends of the base, columns are symmetrically arranged, a stacker lifting platform is fixed between the columns, and the stacker lifting platform is connected with a lifting motor. The characteristics are as follows: the stacker lifting platform includes a stacker lifting platform body, a lifting shaft, and a lifting pulley. The lifting motor is installed on the outer side wall of the stacker lifting platform body. The stacker lifting platform body transversely installs the lifting shaft, the lifting shaft is in a cross shape and penetrates through the stacker lifting platform body to be connected with the lifting motor, the end of the lifting shaft is installed with the lifting pulley, and a longitudinal sliding rail is arranged on the inner surface of the column, and the lifting pulley performs a lifting movement on the longitudinal sliding rail.

[0004] However, the above-mentioned stacker lifting mechanism does not have the function of applying a surrounding protection to the goods during the lifting process, which will cause the goods to fall off the platform due to inertia or vibration during the lifting process, especially during rapid movement or sudden stop. This will not only damage the goods, but also cause harm to the surrounding equipment or personnel. In addition, the lifting platform without protection measures will also cause the goods to tilt or slide during the lifting process, especially for goods with irregular shapes or stacked higher, which will affect the stability and safety of the lifting process. Content of the Utility Model

[0005] The purpose of the utility model is to provide a stacking elevator with a safety protection mechanism to solve the problem of not applying a surrounding protection to the goods during the lifting process proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A stacker lift with a safety protection mechanism comprises: two groups of connecting arms, a top cover is fixedly installed on the upper surface between the two groups of connecting arms, a reduction motor is fixedly installed on the upper surface of the top cover, a winding column is fixedly installed on one end of the output shaft of the reduction motor, a steel wire rope is wound on the outer surface of the winding column, the other end of the steel wire rope is sleeved on the outer surface of a pulling column, the pulling column is fixedly installed on the upper surface of a stacker lift platform, the stacker lift platform is located between the two groups of connecting arms, a protection mechanism is fixedly installed on the upper surface of the stacker lift platform, and the protection mechanism can be buckled on both ends of the stacker lift platform.

[0008] Preferably, guide wheels are rotatably installed on both sides of the stacker lifting platform, and the stacker lifting platform is slidably installed in a limiting groove through the guide wheels on both sides, and the limiting groove is opened on the inner side of the connecting arm.

[0009] Preferably, triangular reinforcement plates are fixedly installed on both sides of the stacker lifting platform, and the triangular reinforcement plates are fastened by a protective mechanism to enclose the goods placed on the upper surface of the stacker lifting platform.

[0010] Preferably, the protective mechanism comprises two groups of L-shaped rods, the two groups of L-shaped rods are fixedly mounted on the upper surface of the stacker lifting platform, one end of the two groups of L-shaped rods are rotatably mounted with a long-stroke electric push rod, one end of the piston rod of the long-stroke electric push rod is rotatably mounted on one end of a docking plate, the docking plate is fixedly mounted on one end of a side panel, one end of the side panel is fixedly mounted with a connecting rod, and the side panels are rotatably mounted on both sides of the stacker lifting platform through the connecting rod.

[0011] Preferably, the two groups of side panels can be pushed by long-stroke electric push rods to fit on both sides of the stacker lifting platform and cooperate with triangular reinforcement plates to form a U-shaped enclosure.

[0012] Preferably, when the L-shaped rod is lifted, the corner of the L-shaped rod will be offset from being blocked by the top cover.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. Through the design of the connecting arm, reduction motor, winding column, wire rope, stacker lifting platform, triangular reinforcement plate and protective mechanism, during the lifting of goods, the goods can be placed on the upper surface of the stacker lifting platform, and then the stacker lifting platform can be turned over by activating the protective mechanism to touch the front and rear sides of the stacker lifting platform for blocking, and the triangular reinforcement plates on the left and right sides of the stacker lifting platform can be used to enclose the goods in the square-shaped enclosure formed by the triangular reinforcement plates and the protective mechanism, forming an effect of enclosing all four sides of the goods, so that the goods can be prevented from falling during the lifting process, reducing the potential danger to operators and surrounding equipment, and significantly improving the safety of the workplace;

[0015] After enclosing the goods, the reduction motor can be started to drive the winding column to wind the steel wire rope, and the steel wire rope will pull on the outer surface of the pulling column on the upper surface of the stacker lifting table, enabling the stacker lifting table to be lifted. During the lifting process of the stacker lifting table, the stacker lifting table will also roll through the guide wheels on both sides in the limit slots opened on the inner side of the connecting arm, enabling the stacker lifting table to be vertical during the lifting process, thereby ensuring the stability of the lifted goods.

Then, the stacker lifting table can, through the triangular reinforcement plates on both sides, enclose the goods within the rectangular enclosure formed by the triangular reinforcement plates and the side enclosure plate, achieving the effect of applying enclosures on all four sides of the goods, enabling it to prevent the goods from falling during the lifting process, reducing potential hazards to operators and surrounding equipment, significantly improving the safety of the workplace, and also being able to prevent the goods from tilting, sliding, or tipping over, ensuring the stability of the goods during transportation and stacking;

[0017] Moreover, this side enclosure plate is a flip-type enclosure, and this flip-type design enables the side enclosure plate to be flipped up and retracted when not in use, without affecting normal operations and storage space; when needed, it can be quickly flipped and closed to provide the protection function, and the operation is very convenient;

[0018] And because the side enclosure plate can be flipped and adjusted in position, it can adapt to goods of different sizes and shapes. For example, when the goods are relatively long, this side enclosure plate will flip into a V shape and touch the two corners on the upper surface of the goods, further enabling it to press and fix the goods on the upper surface of the stacker lifting table, restricting it, thus improving the versatility and flexibility of this stacker.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-6 , the following technical solutions are provided in this embodiment:

[0028] As Figures 1-4 shown, a stacker lift with a safety protection mechanism includes: two groups of connecting arms 1, a top cover 101 is fixedly installed on the upper surface between the two groups of connecting arms 1, a reduction motor 2 is fixedly installed on the upper surface of the top cover 101, a reeling column 201 is fixedly installed at one end of the output shaft of the reduction motor 2, a steel wire rope 202 is wound on the outer surface of the reeling column 201, the other end of the steel wire rope 202 is sleeved on the outer surface of the pulling column 301, the pulling column 301 is fixedly installed on the upper surface of the stacker lifting platform 3, the stacker lifting platform 3 is located between the two groups of connecting arms 1, and a protection mechanism 4 is fixedly installed on the upper surface of the stacker lifting platform 3, and the protection mechanism 4 can be buckled at both ends of the stacker lifting platform 3.

[0029] Guide wheels 303 are rotatably installed on both sides of the stacker lifting platform 3, and the stacker lifting platform 3 is slidably installed in the limit groove 102 through the guide wheels 303 on both sides, and the limit groove 102 is opened on the inner side of the connecting arm 1.

[0030] Triangular reinforcement plates 302 are fixedly installed on both sides of the stacker lifting platform 3, and through the buckling of the protection mechanism 4, the goods placed on the upper surface of the stacker lifting platform 3 can be surrounded.

[0031] Through the design of the connecting arm 1, the reduction motor 2, the winding column 201, the wire rope 202, the stacker lifting platform 3, the triangular reinforcement plate 302 and the protection mechanism 4, during the process of lifting the goods, the goods can be placed on the upper surface of the stacker lifting platform 3, and then the stacker lifting platform 3 can be turned over by starting the protection mechanism 4 to touch the front and rear sides of the stacker lifting platform 3 for blocking, and the triangular reinforcement plates 302 on the left and right sides of the stacker lifting platform 3 can be used to enclose the goods in the square-shaped enclosure formed by the triangular reinforcement plates 302 and the protection mechanism 4, forming an effect of applying enclosure to all four sides of the goods, so that the goods can be prevented from falling during the lifting process, reducing the potential danger to the operator and surrounding equipment, and significantly improving the safety of the workplace;

[0032] After the goods are enclosed inside, the winding column 201 can be driven to wind up the wire rope 202 by starting the reduction motor 2, and the wire rope 202 will pull the outer surface of the pulling column 301 on the upper surface of the stacker lifting platform 3, so that the stacker lifting platform 3 can be lifted. In the process of the stacker lifting platform 3 being lifted, the stacker lifting platform 3 will also roll in the limiting groove 102 provided on the inner side of the connecting arm 1 through the guide wheels 303 on both sides, so that the stacker lifting platform 3 can be vertical during the lifting process, thereby ensuring the stability of the goods being lifted.

[0033] like Figures 5-6 As shown, the protection mechanism 4 includes two groups of L-shaped rods 401, which are fixedly mounted on the upper surface of the stacker lifting platform 3. One end of the two groups of L-shaped rods 401 is rotatably mounted with a long-stroke electric push rod 402. One end of the piston rod of the long-stroke electric push rod 402 is rotatably mounted on one end of a docking plate 403. The docking plate 403 is fixedly mounted on one end of a side panel 404. A connecting rod 405 is fixedly mounted on one end of the side panel 404. The side panels 404 are rotatably mounted on both sides of the stacker lifting platform 3 through the connecting rod 405.

[0034] The two sets of side panels 404 can be pushed by the long-stroke electric push rods 402 to fit on both sides of the stacker lifting platform 3 and cooperate with the triangular reinforcement plates 302 to form a U-shaped enclosure.

[0035] When the L-shaped rod 401 is lifted, the corner of the L-shaped rod 401 will be offset and blocked by the top cover 101 .

[0036] Through the design of the long-stroke electric push rod 402, the docking plate 403, and the side enclosure plate 404, when enclosing the goods, the piston rods of the two groups of long-stroke electric push rods 402 can be activated to push the docking plate 403, so that the docking plate 403 drives the side enclosure plate 404 to flip and abut against both sides of the stacker lifting table 3 through the connecting rod 405. Then, the stacker lifting table 3 can, through the triangular reinforcement plates 302 on both sides, enclose the goods within the rectangular enclosure formed by the triangular reinforcement plates 302 and the side enclosure plate 404, achieving the effect of applying enclosures to all four sides of the goods, enabling it to prevent the goods from falling during the lifting process, reducing potential hazards to operators and surrounding equipment, significantly improving the safety of the workplace, and also preventing the goods from tilting, sliding, or tipping over, ensuring the stability of the goods during transportation and stacking;

[0037] Moreover, this side enclosure plate 404 is a flip-up type of enclosure, and this flip-up design enables the side enclosure plate 404 to be flipped up and retracted when not in use, without affecting normal operations and storage space; when needed, it can be quickly flipped closed to provide the protection function, and the operation is very convenient;

[0038] And because the side enclosure plate 404 can be flipped and adjusted in position, it can adapt to goods of different sizes and shapes. For example, when the goods are relatively long, this side enclosure plate 404 will flip into a V shape and abut against the two corners on the upper surface of the goods, thereby also being able to press and fix the goods on the upper surface of the stacker lifting table 3 and limit it. Therefore, the versatility and flexibility of this stacker are improved.

[0039] Summarize and sort out the working steps of this solution according to the above technical solution: During the process of lifting the goods, after placing the goods on the upper surface of the stacker lifting table 3, the piston rods of the two groups of long-stroke electric push rods 402 can be activated to push the docking plate 403, so that the docking plate 403 drives the side enclosure plate 404 to flip and abut against both sides of the stacker lifting table 3 through the connecting rod 405. Then, the stacker lifting table 3 can, through the triangular reinforcement plates 302 on both sides, enclose the goods within the rectangular enclosure formed by the triangular reinforcement plates 302 and the side enclosure plate 404, achieving the effect of applying enclosures to all four sides of the goods, enabling it to prevent the goods from falling during the lifting process, reducing potential hazards to operators and surrounding equipment. Subsequently, the deceleration motor 2 can be activated to drive the winding column 201 to wind the steel wire rope 202, and the steel wire rope 202 will pull on the outer surface of the pulling column 301 on the upper surface of the stacker lifting table 3, enabling the stacker lifting table 3 to be lifted. When the stacker lifting table 3 is lifted to be flush with the placement platform, the long-stroke electric push rod 402 can be activated again to pull the docking plate 403, enabling the docking plate 403 to pull the side enclosure plate 404 to flip and unfold through the connecting rod 405, providing access for the goods to be removed from the stacker lifting table 3.

[0040] In summary, it enables the object to be enclosed within the rectangular-shaped enclosure formed by the triangular reinforcement plate 302 and the side enclosure plate 404, achieving the effect of applying enclosures on all four sides of the goods, enabling it to prevent the goods from falling during the lifting process, reducing potential hazards to operators and surrounding equipment, and significantly improving the safety of the workplace.
