Description

Technical Field

[0001] The utility model relates to the field of new energy technology, in particular to a hoisting and transporting device. The utility model also relates to a bottom-breaking unpacking machine. Background Art

[0002] With the development of the new energy industry, the market demand for lithium batteries is increasing day by day.

[0003] In the lithium battery industry, the powder required for lithium battery production is mainly packaged and transported in lifting bags, such as ton bags. Ton bags are large packaging bags used for lifting and transportation. They are of high quality, low price and strong structure. During the material preparation or feeding stage, ton bags need to be lifted and transported to the silo for unpacking, breaking and unloading.

[0004] To meet the needs of lithium battery production, various types of unpacking machines have emerged. The first step of the unpacking operation is to lift the ton bag to the designated location, such as above the silo. The traditional ton bag lifting operation mainly adopts the manual bag hanging method, that is, the worker hangs the four slings on the ton bag on the hooks on the electric hoist, and then operates the electric hoist to transport the ton bag to the designated unpacking location. However, when manually hanging the ton bag, the powder in the ton bag often spills everywhere, forming dust, which is easy to cause harm to the health of workers.

[0005] As an improvement, some automatic unpacking machines have appeared in the prior art. It is not necessary to manually hang the four slings on the ton bag on the hooks on the electric hoist, but the operator remotely controls the hooks to move in the central control room. However, the four slings on the ton bag are set on the top, and because they are made of soft rope materials, after being transported to the lifting position, the slings often lie on the top of the ton bag or are buried in the powder pile due to the influence of their own weight. As a result, it is difficult for the operator to remotely and finely control the hook to hook the four slings without the intervention of the on-site workers. Manual intervention is still often required to finely operate the slings on the ton bag, which makes the lifting operation more troublesome.

[0006] Therefore, how to conveniently realize the lifting operation of the lifting bag, avoid the need for manual intervention as much as possible, improve the degree of mechanization, and prevent harm to the health of workers is a technical problem faced by technical personnel in this field.

Another purpose of the utility model is to provide a bottom breaking bag unpacking machine.

[0008] In order to solve the above technical problems, the utility model provides a lifting and transporting device, comprising a lifting mechanism movably and liftably connected to the frame of a bottom-breaking unpacking machine, and a lifting bag for holding materials, at least two side hanging belts are arranged on the outer wall of the lifting bag, the two ends of each side hanging belt are respectively fixed to the outer wall of the lifting bag, and each side hanging belt is distributed opposite to each other in the circumferential direction of the lifting bag;

[0009] The lifting mechanism includes a lifting bracket connected to the frame, and a hook assembly rotatably connected to both sides of the bottom of the lifting bracket and facing each other in the circumferential direction. The hook assembly is used to pass through the gap between the side hanging belt and the outer side wall of the lifting bag from the bottom so that the side hanging belt is hung on the hook assembly.

[0010] Preferably, the cross-section of the lifting bag is rectangular, and the side hanging belts are distributed in pairs on both side walls in the width direction and / or on both side walls in the length direction of the lifting bag.

[0015] Preferably, the driving plate is an L-shaped plate, and the first driving cylinder is connected to one side of the driving plate, and the hook is arranged on the other side of the driving plate.

[0016] Preferably, the top surface of the hook is an inclined surface, so as to enable the side hanging belt to slide toward the root of the hook under the action of its own weight.

[0017] Preferably, a lock hole is provided on the top surface of the hook, a second drive cylinder is provided on the drive plate, a lock pin is slidably provided on the drive plate, and an output end of the second drive cylinder is connected to the lock pin so that the lock pin is inserted into the lock hole.

[0018] The utility model also provides a bottom-breaking unpacking machine, comprising a frame and a hoisting and transporting device arranged on the frame, wherein the hoisting and transporting device is specifically any one of the hoisting and transporting devices described above.

[0019] The lifting and transporting device provided by the utility model mainly includes a lifting mechanism and a lifting bag. Among them, the lifting bag is mainly used to hold materials and can be hung on the lifting mechanism. It is important that a side hanging belt is arranged on the outer wall of the lifting bag, and at least two side hanging belts are arranged, and the two ends of each side hanging belt are respectively fixedly connected to the outer wall of the lifting bag to form a certain gap space between the belt body of the side hanging belt and the outer wall of the lifting bag, and the gap space is mainly used for the lifting mechanism to pass through to form a hanging. At the same time, each side hanging belt is distributed opposite to each other in the circumferential direction of the lifting bag, which is equivalent to the ear of the lifting bag. The lifting mechanism is connected to the frame of the bottom breaking unpacking machine and forms a movable connection with the frame, has horizontal movement freedom and lifting movement freedom, can perform one-dimensional or two-dimensional movement in the horizontal plane, and can perform vertical rising or falling movement, and is mainly used for lifting the lifting bag to change the horizontal position and height position of the lifting bag.

The hook assembly is mainly used to pass through the gap space between the side hanging belt and the outer side wall of the lifting bag from the bottom, so that the side hanging belt is hung on the hook assembly.

[0020] Thus, when the lifting bag is hoisted, the height of the lifting bracket is first lowered on the rack to a suitable height above the lifting bag. Specifically, the hook assembly at the bottom of the lifting bracket is exactly located below the side hanging belt on the lifting bag. Then the hook assembly is slightly flipped inwards so that the hook assembly slightly abuts against the side wall of the lifting bag, and then the side hanging belt is passed through the gap between the side hanging belt and the outer wall of the lifting bag from below, so that the side hanging belt slides into the hook assembly to achieve a hanging connection. After that, the lifting bag can be hoisted to the target position through the horizontal movement and / or lifting movement of the lifting bracket, and then the hook assembly is flipped outwards so that the side hanging belt slides out of the hook assembly and is disconnected from the hanging connection, so that the lifting bag can automatically fall under the action of gravity.

[0021] Compared with the prior art, the lifting and transportation device provided by the utility model no longer uses the slings on the lifting bag for lifting operations, but instead uses the side hanging belts on the outer wall of the lifting bag to lift the lifting bag through the hook assembly. Since both ends of the side hanging belts are fixedly connected to the outer wall of the lifting bag and are located at the lateral position of the lifting bag, the position of the side hanging belts is fixed, and the gap between the side hanging belts and the outer wall of the lifting bag can be stably maintained, which is convenient for the staff to operate the hook assembly to penetrate or the hook assembly to penetrate automatically and controlledly, and is not affected by the powder pile in the lifting bag, and basically does not require the help of the staff to operate, so the lifting operation of the lifting bag can be conveniently realized, and the situation where manual intervention is required is avoided as much as possible, the degree of mechanization is improved, and harm to the health of the workers is prevented.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Please refer to Figure 1 , Figure 1 The present invention is a schematic diagram of the overall structure of a specific implementation method provided by the present invention.

[0031] In a specific implementation manner provided by the present utility model, the hoisting and transportation device mainly includes a hoisting mechanism and a hoisting bag 2 .

[0032] Among them, the lifting bag 2 is mainly used to hold materials and can be hung on the lifting mechanism. It is important that a side hanging belt 3 is provided on the outer wall of the lifting bag 2, and at least two side hanging belts 3 are provided, and the two ends of each side hanging belt 3 are respectively fixedly connected to the outer wall of the lifting bag 2 to form a certain gap space between the belt body of the side hanging belt 3 and the outer wall of the lifting bag 2, and the gap space is mainly used for the lifting mechanism to pass through to form a hanging. At the same time, each side hanging belt 3 is distributed opposite to each other in the circumferential direction of the lifting bag 2, which is equivalent to the ear of the lifting bag 2.

[0033] The lifting mechanism is connected to the frame 1 of the bottom breaking unpacking machine and forms an active connection with the frame 1. It has horizontal movement freedom and lifting movement freedom, can perform one-dimensional or two-dimensional movement in the horizontal plane, and can perform vertical rising or falling movement. It is mainly used to lift the lifting bag 2 to change the horizontal position and height position of the lifting bag 2. The lifting mechanism mainly includes a lifting bracket 4 and a hook assembly 5. Among them, the lifting bracket 4 is connected to the frame 1 and is mainly used to install the remaining parts of the lifting mechanism. The hook assembly 5 is connected to the bottom of the lifting bracket 4, and at least two are provided, and are respectively located at the bottom of the lifting bracket 4. The two sides are located at the same time. They are also distributed in the circumferential direction of the lifting bracket 4 and correspond to the side hanging belt 3 on the lifting bag 2. At the same time, the hook assembly 5 is connected to the lifting bracket 4 in a rotating manner and can perform inward or outward turning movement. The hook assembly 5 is mainly used to pass through the gap space between the side hanging belt 3 and the outer wall of the lifting bag 2 from the bottom so that the side hanging belt 3 is hung on the hook assembly 5.

[0034] Thus, when the lifting bag 2 is lifted, the height of the lifting bracket 4 is first lowered on the frame 1 to a suitable height above the lifting bag 2. Specifically, the hook assembly 5 at the bottom of the lifting bracket 4 is located just below the side hanging belt 3 on the lifting bag 2. Then the hook assembly 5 is slightly flipped inwards so that the hook assembly 5 slightly abuts against the side wall of the lifting bag 2, and then passes through the gap between the side hanging belt 3 and the outer wall of the lifting bag 2 from below, so that the side hanging belt 3 slides into the hook assembly 5 to achieve a hanging connection. After that, the lifting bag 2 can be lifted to the target position through the horizontal movement and / or lifting movement of the lifting bracket 4, and then the hook assembly 5 is flipped outwards so that the side hanging belt 3 slides out of the hook assembly 5 and is disconnected from the hanging connection, so that the lifting bag 2 can automatically fall under the action of gravity.

[0035] Compared with the prior art, the lifting and transportation device provided in the present embodiment no longer uses the lifting straps on the lifting bag 2 for lifting when lifting the lifting bag 2. Instead, the side hanging straps 3 on the outer wall of the lifting bag 2 are hung by the hook assembly 5. Since both ends of the side hanging straps 3 are fixedly connected to the outer wall of the lifting bag 2 and are located at the lateral position of the lifting bag 2, the position of the side hanging straps 3 is fixed, and the gap between the side wall and the lifting bag 2 can be stably maintained, which is convenient for the staff to operate the hook assembly 5 to penetrate or the hook assembly 5 to penetrate automatically and controlledly, and is not affected by the powder pile in the lifting bag 2, and basically does not require the staff to help with the operation. Therefore, the lifting operation of the lifting bag 2 can be conveniently realized, and the situation where manual intervention is required can be avoided as much as possible, thereby improving the degree of mechanization and preventing harm to the health of workers.

[0036] In a specific embodiment of the lifting bag 2, the cross-section of the lifting bag 2 is specifically rectangular, such as a rectangle or a square. At the same time, the side hanging belts 3 are distributed in pairs on the two side walls in the width direction of the lifting bag 2, or in pairs on the two side walls in the length direction of the lifting bag 2, and can also be distributed on the two side walls in the width direction and the two side walls in the length direction of the lifting bag 2 at the same time. For example, there are two side hanging belts 3, which are respectively arranged on the two side walls in the width direction or the length direction of the lifting bag 2; or, there are four side hanging belts 3, which are respectively arranged on the four side walls of the lifting bag 2. Of course, more than one side hanging belt 3 can be arranged on each side wall of the lifting bag 2, for example, two side hanging belts 3 or more can be arranged on one side wall.

[0037] In another specific embodiment of the lifting bag 2, the cross section of the lifting bag 2 is specifically circular. At the same time, the side hanging belts 3 are distributed in pairs at the radial ends of the outer circumference of the lifting bag 2. For example, there are two side hanging belts 3, which are respectively arranged at the two ends of a certain diameter direction of the lifting bag 2.

[0038] With such arrangement, the side hanging belts 3 are distributed in pairs and opposite to each other in the circumferential direction on the lifting bag 2, which can ensure balance during hanging and avoid tilting and deflection of the lifting bag 2.

[0039] like Figure 3 As shown, Figure 3 It is a schematic diagram of the specific structure of the lifting bag 2.

[0040] In a specific embodiment of the side hanging strap 3, the side hanging strap 3 is specifically an elastic strap, such as a cloth strap, a belt, a plastic strap, a soft metal strap, etc., and on the basis that the two ends of the strap body are respectively fixedly connected to the outer wall of the lifting bag 2, the length of the strap body has a certain redundancy, so that the strap body of the side hanging strap 3 does not remain in close contact with the outer wall of the lifting bag 2, that is, it is not in a tight state, but in a relaxed state, so that a certain gap space is left between the strap body of the side hanging strap 3 and the outer wall of the lifting bag 2.

[0041] In another specific embodiment of the side hanging belt 3, the side hanging belt 3 is specifically an arc-shaped belt that arches in a direction away from the outer side wall of the lifting bag 2. In this case, the side hanging belt 3 can be a belt made of non-elastic material or an elastic material. In this way, the arc-shaped arched structure of the side hanging belt 3 is utilized to always maintain a gap space of a fixed size between the side hanging belt 3 and the outer side wall of the lifting bag 2 (regardless of the deformation of the lifting bag 2 itself), so that the hook assembly 5 can be inserted easily.

[0042] like Figure 2 As shown, Figure 2 It is a schematic diagram of the specific structure of the lifting mechanism.

[0043] In a specific embodiment of the hook assembly 5, the hook assembly 5 mainly includes a lifting connecting rod 51, a driving plate 52, a first driving cylinder 53 and a hook 54. The lifting connecting rod 51 is connected to the bottom of the lifting bracket 4, and generally extends a preset length downward in the vertical direction. The driving plate 52 is connected to the bottom end of the lifting connecting rod 51, and forms a rotation connection with the lifting connecting rod 51, such as being connected or hinged by a pin shaft. The first driving cylinder 53 is connected to the bottom of the lifting bracket 4, and the output end of the first driving cylinder 53 is connected to the driving plate 52, which is mainly used to drive the driving plate 52 to rotate inward or outward relative to the lifting connecting rod 51 (i.e. swing) through the linear motion of the piston rod of the first driving cylinder 53. The hook 54 is arranged on the driving plate 52, generally arranged at the bottom position of the driving plate 52, and extends inwardly, and is mainly used to hang the side hanging belt 3. In this arrangement, when the piston rod of the first driving cylinder 53 is extended, it will push the driving plate 52 to rotate outward, thereby driving the hook 54 away from the lifting bag 2; conversely, when the piston rod of the first driving cylinder 53 is retracted, it will push the driving plate 52 to rotate inward, thereby driving the hook 54 to approach the lifting bag 2 until it abuts against the outer wall of the lifting bag 2 and passes through the gap between the side hanging belt 3 and the outer wall of the lifting bag 2 from below, thereby realizing the hanging connection of the side hanging belt 3 on the hook 54.

[0044] In a specific embodiment of the driving plate 52, the driving plate 52 is specifically an L-shaped plate, that is, it includes two mutually perpendicular sides, and the piston rod of the first driving cylinder 53 is connected to one side of the driving plate 52, and the hook 54 is specifically arranged on the other side of the driving plate 52. In this way, the linear motion of the piston rod of the first driving cylinder 53 can be conveniently converted into the rotational motion of the driving plate 52. Of course, the driving plate 52 is not limited to the L-shaped plate structure, and other structures such as triangular structure, wedge structure, etc., or a linear structure but connected to the piston rod of the first driving cylinder 53 through other transmission mechanisms that can change the transmission direction, etc., are also feasible.

[0045] In a specific embodiment of the hook 54, in order to facilitate the side hanging belt 3 to slide smoothly into the hook 54 to form a stable hanging connection, in this embodiment, the top surface of the hook 54 is specifically an inclined surface. Specifically, the low point of the inclined surface is located at the root connected to the hanging connecting rod 51, and the high point is located at the outer end, facing the hanging bag 2, and the slope is generally between 15° and 45°. In this way, when the outer end of the hook 54 abuts against the outer wall of the hanging bag 2 and just penetrates the gap between the side hanging belt 3 and the hanging bag 2, the side hanging belt 3 can slide along the inclined surface of the hook 54 to the root of the hook 54 under the action of its own weight to achieve stable hanging.

[0046] In order to prevent the side hanging belt 3 from accidentally detaching from the hook 54 during the lifting process, in this embodiment, a lock hole is provided on the top surface of the hook 54, and the lock hole can be a through hole or a blind hole. At the same time, a second driving cylinder 55 is provided on the outer side of the driving plate 52, and a lock pin 56 is provided on the inner side of the driving plate 52. Specifically, the lock pin 56 is slidably provided on the inner side of the driving plate 52, and the top end of the lock pin 56 passes through the plate body of the driving plate 52 and is connected to the output end (i.e., the piston rod) of the second driving cylinder 55. The output end of the second driving cylinder 55 can move linearly along the extension direction (such as the length direction) of the driving plate 52, so as to drive the lock pin 56 to move synchronously on the driving plate 52 through the second driving cylinder 55, and then the lock pin 56 can move linearly toward the hook 54 until the bottom end of the lock pin 56 is inserted into the lock hole on the hook 54 to achieve locking. Of course, a through hole or a slit can also be provided on the driving plate 52 to avoid the top end of the lock pin 56. With such arrangement, after the side hanging belt 3 slides into the root position of the hook 54 to form a hanging connection, the second driving cylinder 55 can drive the locking pin 56 to move toward the hook 54 (such as vertical downward movement) until the bottom end of the locking pin 56 is inserted into the locking hole on the hook 54, so that the locking pin 56, the hook 54 and the driving plate 52 together form a temporary closed space, locking the side hanging belt 3 in the closed space, thereby preventing the side hanging belt 3 from accidentally detaching from the hook 54 during the lifting process.

[0047] The present embodiment further provides a bottom-breaking unpacking machine, which mainly includes a frame 1 and a lifting and transporting device arranged on the frame 1. Since the lifting and transporting device adopts all the technical solutions of the above-mentioned lifting and transporting device embodiments, the bottom-breaking unpacking machine provided in the present embodiment also has all the technical effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0048] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
