Description

Technical Field

[0001] The invention relates to the technical field of stacking equipment, in particular to an anti-falling device for a high-position stacker. Background Art

[0002] Stacker crane is a kind of automated equipment widely used in the field of logistics and warehousing. It is mainly used to stack goods neatly on shelves or take goods out from shelves to realize the automated storage and handling of goods.

[0003] In the field of stacking equipment technology, a high-level stacker is a device used for storing and retrieving goods at high altitudes in warehousing and logistics. It uses a lifting mechanism to transport goods to a designated high-altitude location to achieve stacking and sorting of goods. However, traditional high-level stackers have certain safety risks during operation, especially in unexpected situations such as chain breakage. There is a lack of effective anti-fall mechanisms to protect the safety of goods and equipment. In the absence of an anti-fall device, once the chain breaks, the mobile frame will fall rapidly due to the loss of upward force, which may not only cause damage to the goods, but also cause serious harm to people and equipment on the ground. In addition, traditional high-level stackers often require operators to manually apply emergency brakes in emergency situations, which may be difficult to respond in time, increasing the risk of accidents.

[0004] Therefore, the existing high-position stacker has obvious deficiencies in safety, especially in preventing accidental falls and ensuring operational safety. The existence of these problems not only affects the efficiency of stacking operations, but also poses a threat to the safety of operators and equipment. Therefore, it is necessary to develop a high-position stacker with an anti-fall function to improve its safety performance in unexpected situations, reduce the occurrence of accidents, and ensure the safety of personnel and equipment.

[0018] The present invention provides a fall prevention device for a high-position stacker. The device has the following beneficial effects:

[0019] 1. The anti-fall device of this high-position stacker loses its pulling effect on the slider when the chain breaks, causing the slider to move instantly into the inside of the working cover. The continued sliding of the slider will reset the airbag assembly, and the impact force will generate an extrusion force on the airbag assembly, which will further compress the internal space of the airbag assembly, causing the expansion bag to expand outward instantly, thereby releasing the buffer plate and making frictional contact with the inner surface of the auxiliary plate and the mounting frame, greatly reducing the falling speed of the mobile frame. At the same time, as the expansion bag continues to expand, the friction force of the buffer plate will gradually increase, and the elastic telescopic plate will be squeezed. Then the plug-in plate is connected with the card slot through the plug-in slot, automatically realizing the forced stop of the mobile frame to prevent the goods from falling, and solving the problem that the current manual stacking equipment cannot produce an excellent anti-fall mechanism when the chain breaks.

[0020] 2. The anti-fall device of this high-position stacker first slows down the downward speed of the mobile frame through the friction of the buffer plate, so that the plug-in plate can be plugged into the card slot more stably, avoiding the problem of the plug-in plate contacting the card slot and causing breakage when moving at high speed, greatly improving the service life and working stability of this device. At the same time, the auxiliary roller is arranged to cooperate with the first roller and the second roller, so that the movement of the mobile frame always remains stable, avoiding the problem that the mobile frame is subjected to greater pressure when carrying heavier goods, which causes greater pressure on the first roller and the second roller, resulting in the plug-in plate being unable to be plugged into the card slot when the chain breaks.

[0021] 3. The anti-fall device of this high-position stacker will squeeze the airbag assembly through the working plate during the instantaneous reset of the slider, thereby further reducing the distance between the pressure plates. At this time, the folded deformation plate is compressed more severely, and its elastic potential energy increases. Under the action of pressure, the sealing plate will fit better between the pressure plate and the deformation plate due to its rubber material and the thinner wall thickness on both sides than the middle wall thickness, thereby ensuring the sealing of the cavity and preventing gas leakage, thereby making the air pressure change inside the airbag assembly relatively stable, avoiding the impact of sudden changes in air pressure on subsequent work, and at the same time, it can also produce a strong tolerance effect on the deformation of the deformation plate, greatly improving the working stability of the airbag assembly. When the deformable plate is deformed, it squeezes the second telescopic plate, prompting the second telescopic plate to move into the inside of the first telescopic plate, and realizes the overall downward movement of the stabilizing plate at the bottom of the first telescopic plate, thereby controlling the deformable plate to always maintain a stable compressed state, and then maintaining a good air pressure conveying effect when the chain breaks to force the mobile rack to stop, greatly improving the working stability and safety of the device, avoiding the problem of abnormal deformation of the airbag assembly affecting the air pressure conveying and causing the cargo to fall, and compared with the currently commonly used airbags, not only is the structure more stable, but it can also provide good elastic force, solving the problem of conventional airbags being in a strong tensile state for a long time, causing the elastic force to drop too quickly and lose performance.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] First embodiment: Figures 1 to 8As shown, the present invention provides a technical solution: an anti-fall device for a high-position stacker, comprising a base frame 1, wherein both ends of the base frame 1 are rotatably connected to a moving wheel group 2, the moving wheel group 2 includes four moving wheels, wherein the moving wheel group 2 supports the device for movement, the upper surface of the base frame 1 is fixedly connected to a mounting frame 3, wherein the mounting frame 3 and the base frame 1 are arranged perpendicular to each other, and a push handle 4 is fixedly connected to the middle outer surface of the mounting frame 3, and further comprising:

[0033] The stacking mechanism 5 is movably connected to the mounting frame 3, wherein the stacking mechanism 5 supports the device to perform stacking work, and the stacking mechanism 5 moves up and down on the mounting frame 3;

[0034] The airbag assembly 6 is fixedly mounted inside the stacking mechanism 5 and provides an additional power source for the stacking mechanism 5;

[0035] The stacking mechanism 5 includes a hydraulic rod 51, the bottom of which is fixedly connected to the upper surface of the base frame 1, and a driving rod 52 is fixedly connected to the outer surface of the bottom of the hydraulic rod 51. The driving rod 52 is initially arranged relatively parallel to the hydraulic rod 51, and the driving rod 52 controls the rise and fall of the hydraulic rod 51. A stabilizing rod 53 is fixedly connected to the outer surface of the middle part of the hydraulic rod 51, and the bottom of the stabilizing rod 53 is fixedly connected to the bottom of the hydraulic rod 51. The stabilizing rod 53 limits the movement of the driving rod 52.

[0036] The top of the hydraulic rod 51 is rotatably connected to a pulley 54, and the pulley 54 is rotatably connected to a chain 55. The movable end of the chain 55 is fixedly connected to a movable frame 56, and the fixed end of the chain 55 is fixedly connected to a slider 57. The outer surface of the end of the movable frame 56 away from the hydraulic rod 51 is fixedly connected to a protective frame 58, and the middle of the protective frame 58 is fixedly connected to a mounting plate 59, and the top two ends of the mounting plate 59 are symmetrically fixedly connected to stacking rods 510.

[0037] The middle outer surface of the hydraulic rod 51 is fixedly connected to the working cover 511, the bottom of the slider 57 is slidably connected to the top of the working cover 511, the inner surfaces of both ends of the mounting frame 3 are symmetrically fixedly connected to the auxiliary plates 512, and the outer surface of one end of the movable frame 56 away from the protective frame 58 is slidably connected to the surface of the auxiliary plate 512 close to the hydraulic rod 51.

[0038] The top outer surface of the movable frame 56 is symmetrically connected to the first roller 513, and the bottom outer surface of the movable frame 56 is rotatably connected to the second roller 514, wherein the first roller 513 and the second roller 514 are longitudinally staggered, and the outer surfaces of the first roller 513 and the second roller 514 are respectively rotatably connected to the inner and outer surfaces of the mounting frame 3 close to the protective frame 58.

[0039] The inner surface of the working cover 511 is symmetrically fixedly connected with a slide rod 515, and the slide rod 515 is elastically slidably connected with a working plate 516 through a spring, wherein the working plate 516 is semicircular, and the middle upper surface of the working plate 516 is fixedly connected to the bottom surface of the slider 57, and the bottom surface of the working plate 516 is fixedly connected to the upper surface of the airbag assembly 6, and the bottom surface of the airbag assembly 6 is fixedly connected to the bottom inner surface of the working cover 511.

[0040] The outer surfaces of both ends of the movable frame 56 are fixedly connected with mounting covers 517, and the outer surfaces of both ends of the mounting covers 517 are symmetrically fixedly connected with mounting rods 518, wherein three mounting rods 518 are arranged in a group, and one end of the mounting rod 518 away from the mounting cover 517 is rotatably connected with an auxiliary roller 519, and the auxiliary rollers 519 on both sides rotate and fit on the inner surfaces of the auxiliary plate 512 and the mounting frame 3 respectively.

[0041] An expansion bag 520 is fixedly connected to the inside of the mounting cover 517, wherein the expansion bag 520 is communicated with the airbag assembly 6, and push plates 521 are symmetrically fixedly connected to the outer surfaces of both sides of the expansion bag 520, and the upper and lower ends of the push plates 521 are slidably connected to the upper and lower inner surfaces of the mounting cover 517, and the outer surface of the push plates 521 is symmetrically fixedly connected to the elastic expansion plates 522, and the outer ends of the elastic expansion plates 522 pass through the outer surface of the mounting cover 517 and are fixedly connected to the buffer plates 523, wherein the buffer plates 523 are inserted between the mounting rods 518, and the outer surfaces of both ends of the buffer plates 523 are penetrated with plug-in grooves 524, and the outer surfaces of both ends of the push plates 521 are symmetrically fixedly connected with plug-in plates 525, and the outer ends of the plug-in plates 525 are slidably penetrated and plugged into the outer surface of the mounting cover 517, and the outer surface of the auxiliary plate 512 is penetrated with a snap-in groove 526, and the inner surface of the mounting frame 3 close to the protective frame 58 is also penetrated with a snap-in groove 526.

[0042] During operation, if high-position stacking is required, the entire device can be applied with force by pushing the handle 4, and the mobile wheel group 2 connected by the rotation of the two ends of the base frame 1 drives the entire high-position stacker to move to the designated working position, and then the goods are placed on the stacking rod 510, and the stacking operation is realized by controlling the driving rod 52 to control the mobile frame 56 to move up and down. When the stacking rod 510 carries the goods, the gravity of the goods is transmitted to the mobile frame 56 through the stacking rod 510, the mounting plate 59 and the protective frame 58, so that the mobile frame 56 has a tendency to move downward. Since the mobile frame 56 is connected to the slider 57 through the chain 55, the downward movement of the mobile frame 56 will pull the chain 55, and the fixed end of the chain 55 pulls the slider 57 to slide upward on the top of the working cover 511, and the slider 57 moves upward. The upward sliding will produce a stretching effect on the airbag assembly 6, which will increase the internal space of the airbag assembly 6 and reduce the air pressure to a negative pressure state. When the airbag assembly 6 is under negative pressure, the expansion bag 520 connected thereto will shrink. The shrinkage of the expansion bag 520 drives the push plate 521 to move inward. The movement of the push plate 521 drives the buffer plate 523 to shrink inward through the elastic telescopic plate 522, so that the buffer plate 523 does not contact the auxiliary plate 512 and the mounting frame 3. At this time, the auxiliary roller 519 always maintains a fitting state. Through the cooperation of the first roller 513, the second roller 514 and the auxiliary roller 519, the movable frame 56 can move normally on the mounting frame 3. When the chain 55 breaks, it loses the pulling effect on the slider 57, causing the slider 57 to move instantly into the working cover 511. The continued sliding of the slider 57 will reset the airbag assembly 6, and the impact force will generate an extrusion force on the airbag assembly 6, so that the internal space of the airbag assembly 6 will be further compressed, that is, the expansion bag 520 will expand outward instantly, so that the buffer plate 523 will be released and frictionally contact with the inner surface of the auxiliary plate 512 and the mounting frame 3, greatly reducing the falling speed of the mobile frame 56. At the same time, as the expansion bag 520 continues to expand, the friction force of the buffer plate 523 will gradually increase, and the elastic telescopic plate 522 will be squeezed. Then the plug-in plate 525 is connected with the card slot 526 through the plug-in slot 524, automatically realizing the forced stop of the mobile frame 56 to prevent the goods from falling, and solving the problem that the current manual stacking equipment cannot produce excellent anti-falling when the chain 55 breaks. The problem of the falling mechanism is solved, and the downward movement speed of the mobile frame 56 is first slowed down by the friction force of the buffer plate 523, so that the plug-in plate 525 can be plugged into the card slot 526 more stably, avoiding the problem that the plug-in plate 525 contacts the card slot 526 when moving at high speed and causes breakage, greatly improving the service life and working stability of the device. At the same time, the auxiliary roller 519 is arranged to cooperate with the first roller 513 and the second roller 514 to ensure that the movement of the mobile frame 56 always remains stable, avoiding the problem that the mobile frame 56 is subjected to greater pressure when carrying heavier goods, causing greater pressure on the first roller 513 and the second roller 514, resulting in the plug-in plate 525 being unable to complete the plug-in connection with the card slot 526 when the chain 55 breaks.

[0043] Second embodiment: Figures 1 to 8 As shown, the airbag assembly 6 includes a pressure plate 61, wherein two pressure plates 61 are arranged in parallel, and the inner surfaces at both ends of the pressure plate 61 are symmetrically fixedly connected with a deformable plate 62, which is arranged in a foldable shape and is arranged as an elastic plate.

[0044] The inner surface of the deformation plate 62 is symmetrically fixedly connected with a sealing plate 63, which is made of rubber material. The wall thickness on both sides of the sealing plate 63 is thinner than the wall thickness in the middle, wherein the sealing plate 63 seals the cavity between the pressure plate 61 and the deformation plate 62. A first telescopic plate 64 is arranged between the two pressure plates 61, and a second telescopic plate 65 is symmetrically elastically slidably inserted at both ends of the first telescopic plate 64. The outer end of the second telescopic plate 65 is fixedly connected to the middle inner surface of the deformation plate 62, and the bottom surface of the first telescopic plate 64 is fixedly connected to a stabilizing plate 66. The bottom of the stabilizing plate 66 passes through and is slidably connected to the outer surface of the bottom pressure plate 61.

[0045] During operation, during the instantaneous reset of the slider 57, the airbag assembly 6 will be squeezed through the working plate 516, thereby further reducing the distance between the pressure plates 61. At this time, the folded deformation plate 62 is compressed more severely, and its elastic potential energy increases. Under the action of pressure, the sealing plate 63, due to its rubber material and the characteristics that the wall thickness on both sides is thinner than the wall thickness in the middle, will fit better between the pressure plate 61 and the deformation plate 62, ensuring the sealing of the cavity and preventing gas leakage, so that the air pressure change inside the airbag assembly 6 is relatively stable, avoiding the sudden change of air pressure affecting subsequent work, and at the same time, it can also produce a strong tolerance effect on the deformation of the deformation plate 62, greatly improving the working stability of the airbag assembly 6, and at the same time, the deformation plate 6 When the deformation occurs, the second telescopic plate 65 is squeezed, causing the second telescopic plate 65 to move into the inside of the first telescopic plate 64, and the stabilizing plate 66 at the bottom of the first telescopic plate 64 is moved downward as a whole, thereby controlling the deformable plate 62 to always maintain a stable compressed state, thereby maintaining a good air pressure conveying effect when the chain 55 breaks, and forcing the mobile frame 56 to stop, greatly improving the working stability and safety of the device, and avoiding the problem that the abnormal deformation of the airbag assembly 6 affects the air pressure conveying and causes the cargo to fall. In addition, compared with the currently commonly used airbags, not only is the structure more stable, but it can also provide good elastic force, solving the problem that the conventional airbags are in a strong tensile state for a long time, causing the elastic force to drop too quickly and lose performance.
