Description

Technical Field

[0001] The present application relates to the technical field of grab bucket transfer devices, and in particular to a fully automatic wireless remote-controlled multi-petal grab bucket carrier. Background Art

[0002] A multi-jaw grab is a specialized tool used by cranes to grab dry bulk cargo. It consists of multiple openable and closable bucket-shaped jaws that form a container. During loading, the jaws close within the pile, pulling the material into the container. During unloading, the jaws open while suspended above the pile, releasing the material onto the pile. The jaws are typically controlled by a wire rope on the crane. Multi-jaw grabs eliminate the need for heavy manual labor, achieve high loading and unloading efficiency, and ensure safety, making them a key tool for handling dry bulk cargo at ports.

[0003] During transportation work at the dock, it is often necessary to transfer multi-petal grabs between two locations, and the transfer process of the multi-petal grab needs to be achieved through a trailer. First, multiple support bases are installed on the trailer, and then the multi-petal grab on the crane is transported to the trailer. The multi-petal grab is positioned by the support base to prevent it from tipping over; then the multi-petal grab is transported to the desired location by the trailer. On the one hand, this transfer method requires the installation of support bases at corresponding positions on the trailer according to the structure of the multi-petal grab. On the other hand, during the transfer of the multi-petal grab, the trailer driver cannot accurately observe the condition of the multi-petal grab and requires the cooperation of personnel standing on the ground to observe the condition of the multi-petal grab. Therefore, the transfer process of the multi-petal grab is relatively cumbersome. Summary of the Invention

[0004] In order to make the transportation process of the multi-petal grab bucket more convenient, the present application provides a fully automatic wireless remote-controlled multi-petal grab bucket carrier.

[0005] The present application provides a fully automatic wireless remote-controlled multi-flap grab bucket carrier adopts the following technical solution:

[0006] A fully automatic wireless remote-controlled multi-flap grab bucket carrier, comprising:

[0007] base;

[0008] Support seats, fixedly connected to the base, the number of the support seats being the same as the number of jaws of the multi-petal grab bucket, the support seats being arranged in a circular array, and each of the support seats being used to abut against the bottom end of one of the jaws of the multi-petal grab bucket;

[0009] The driving mechanism includes a driving wheel, a driven wheel and a power assembly, wherein the driving wheel and the driven wheel are respectively arranged on both sides of the base, and the power assembly is arranged on the base for driving the driving wheel to rotate;

[0010] A protective mechanism is provided on the outside of the support seat, comprising a baffle, a mounting tube, a torsion spring, and a first drive assembly. The number of the baffles is the same as the number of the support seats, and each baffle corresponds to a support seat. The baffle is used to abut against the outside of the multi-petal grab bucket. The mounting tube is fixedly connected to one end of the baffle, and the mounting tube is rotatably connected to the base. The torsion spring is connected between the mounting tube and the base, and the torsion spring causes the baffle on the mounting tube to rotate toward a side away from the support seat.

[0011] The number of the first drive components is the same as the number of baffles, and each of the first drive components corresponds to a baffle. The first drive component includes an active rack, a driven gear and a support rod. The driven gear is coaxially fixed to the mounting cylinder, and the active rack is vertically slidably arranged on the base. The active rack is meshed with the driven gear, and the support rod is fixedly connected to the active rack. The support rod is used to abut against the bottom end of the multi-petal grab bucket so that the support rod and the active rack can be driven to slide during the downward sliding of the multi-petal grab bucket, and the active rack drives the driven gear to rotate, and the driven gear drives the mounting cylinder and the baffle to rotate toward the side close to the support seat.

[0012] By adopting the above technical solution, the support seat can realize automatic positioning and firm support of the multi-petal grab, avoiding the multi-petal grab from tipping over or falling during transportation, thereby improving the safety and reliability of transportation; at the same time, through wireless remote control, the operator can remotely control the movement of the carrier vehicle without relying on the cooperation of ground personnel, simplifying the transportation process of the multi-petal grab and improving work efficiency; in the process of installing the multi-petal grab on the base, the downward movement of the multi-petal grab can cause the support rod and the active rack to move downward, and the driven gear to rotate, causing the mounting cylinder and the baffle to rotate inward until the baffle is against the multi-petal grab, thereby protecting the multi-petal grab. Since the rotation process of the baffle can be controlled by The multi-petal grab is driven by the falling process of the multi-petal grab without the need for an additional power source, which is more energy-efficient; the rotation process of the baffle can be carried out synchronously with the downward movement of the multi-petal grab, which helps to improve work efficiency; after the multi-petal grab is placed on the support seat, due to the large weight of the multi-petal grab, the multi-petal grab is not easy to move upward during the transportation of the multi-petal grab, which makes it impossible for the active rack to move upward, thereby limiting the rotation of the driven gear and the mounting cylinder, thereby limiting the rotation of the baffle, so that the position of the baffle is fixed, and the baffle can protect the middle and upper part of the multi-petal grab, thereby further reducing the possibility of the multi-petal grab tipping over and improving the safety of the device.

[0013] Optionally, the power assembly includes a first motor, a slewing bearing, a connecting seat and a second motor, the first motor is arranged on the base, the output shaft of the first motor is connected to the slewing bearing, the connecting seat is fixedly connected to the slewing bearing, the second motor is arranged on the connecting seat, and the output shaft of the second motor is connected to the driving wheel.

[0014] By adopting the above technical solution, the combined use of the first motor and the slewing bearing realizes the overall steering function of the carrier and improves the maneuverability of the carrier; the setting of the second motor enables the driving wheel to obtain stable power input, thereby ensuring the smooth operation of the carrier.

[0015] Optionally, a positioning plate is fixedly connected to the support seat, and two positioning plates are provided and arranged at intervals.

[0016] By adopting the above technical solution, the two spaced positioning plates fixedly connected to the support seat can position the multi-petal grab bucket, so that the reinforcement ribs on the outside of each jaw plate of the multi-petal grab bucket can accurately offset the corresponding support seat. At the same time, the two positioning plates are respectively located on both sides of the reinforcement ribs on the outside of the jaw plate, thereby preventing the jaw plate from detaching from the support seat, thereby improving the safety and reliability of the multi-petal grab bucket transportation process.

[0017] Optionally, an abutment plate is slidably provided on the baffle, and a spring is connected between the abutment plate and the baffle, and the spring causes the abutment plate to have a tendency to slide toward a side away from the baffle, and the abutment plate is used to abut against the outer side of the multi-petal grab bucket.

[0018] By adopting the above technical solution, the abutment plate is tightly fitted to the outside of the multi-petal grab bucket under the action of the spring, thereby preventing the multi-petal grab bucket from shaking or shifting during transportation, and improving the safety and reliability of transportation; because the abutment plate is tightly pressed against the outside of the multi-petal grab bucket, the abutment plate will apply oblique downward pressure to the multi-petal grab bucket. The pressure applied by the abutment plate to the multi-petal grab bucket and the gravity of the multi-petal grab bucket itself can make the multi-petal grab bucket more stably placed on the support seat, thereby enhancing the safety of the multi-petal grab bucket transportation process.

[0019] Optionally, a guard plate is fixedly connected to a side of the abutting plate away from the baffle, and two guard plates are provided and are respectively located on both sides of the abutting plate.

[0020] By adopting the above technical solution, the two guard plates are respectively located on both sides of the inclined connecting rod on the multi-petal grab, thereby preventing the connecting rod from being out of contact with the abutment plate, thereby further limiting the rotation of the multi-petal grab and enhancing the limiting effect of the multi-petal grab.

[0021] Optionally, a locking mechanism is provided on the base, and the locking mechanism includes a connecting ring, a plug rod and a second drive assembly. The connecting ring is rotatably provided on the base, and the plug rod is fixedly connected to the connecting ring. The number of the plug rods is the same as the number of baffles and each plug rod corresponds to a baffle. A connecting plate is fixedly connected to the baffle, and a first socket for inserting the plug rod is provided on the connecting plate. When the plug rod is inserted into the first socket, the baffle is against the outer side of the multi-petal grab. The second drive assembly is provided on the base, and is used to drive the connecting ring to rotate so that the plug rod on the connecting ring is inserted into the first socket or slides out of the first socket.

[0022] By adopting the above technical solution, the insertion rod into the first socket can limit the rotation of the connecting plate and the baffle, thereby locking the position of the baffle, which helps to improve the stability of the baffle; therefore, when the carrier moves on an inclined ground or the ground is uneven, the multi-petal grab is not prone to tipping or shaking, thereby ensuring the safety of the transfer process; the setting of the second drive component realizes the automatic control of the locking mechanism, further improving the convenience and reliability of operation.

[0023] Optionally, the end of the insertion rod is arranged in a hemispherical shape.

[0024] By adopting the above technical solution, the end of the insertion rod is easier to insert into the first insertion hole, and the working process is smoother.

[0025] Optionally, the second drive assembly includes a third motor, a driving gear and a driven gear ring, the third motor is arranged on the base, the driving gear is coaxially fixedly connected to the output shaft of the third motor, the driven gear ring is coaxially fixedly connected to the connecting ring, and the driving gear is meshed with the driven gear ring.

[0026] By adopting the above technical solution, the third motor drives the driving gear to rotate, and the driving gear engages with the driven gear ring, thereby driving the connecting ring to rotate, and then driving the insertion rod to insert or withdraw from the first hole on the connecting plate, thereby achieving reliable locking and unlocking of the baffle and avoiding the inconvenience caused by manual operation.

[0027] Optionally, the connecting plate is an arc-shaped plate, the axis of the connecting plate and the rotation axis of the baffle are coaxially arranged, and a second socket for inserting the rod is opened on the connecting plate. When the rod is inserted into the second socket, the baffle is vertically arranged.

[0028] By adopting the above technical solution, the connecting plate is designed as an arc-shaped plate and is coaxially arranged with the rotation axis of the baffle, which can effectively ensure that the first hole and the second hole on the connecting plate cooperate with the insertion rod more smoothly during the rotation of the baffle; since the second hole is provided on the connecting plate, when the carrier is not working, the insertion rod can be inserted into the second hole to lock the baffle in a vertical state, which can reduce the space occupied by the carrier; when the multi-petal grab bucket needs to be loaded onto the carrier subsequently, it is only necessary to pull the insertion rod out of the second hole; in addition, after inserting the insertion rod into the second hole, the stability of the baffle in the vertical state can be improved. At this time, the torsion spring is in an untwisted state. Therefore, when the torsion spring is damaged, it can be directly replaced in this state. During replacement, the operator does not need to hold the baffle all the time, which is more convenient.

[0029] Optionally, a generator set for supplying power to the power assembly is provided on the base, and a rain shield is provided on the top of the generator set.

[0030] By adopting the above technical solution, the generator set can supply power to the power components, allowing the carrier to operate stably in the outdoor dock area; the rain shield can protect the generator set, helping to ensure the normal operation of the generator set.

[0031] In summary, this application has the following beneficial technical effects:

[0032] 1. After the multi-petal grab is placed on the support seat, the positioning plate on the support seat can limit the reinforcement ribs at the bottom end of the jaw plate of the multi-petal grab, thereby improving the stability of the multi-petal grab and making it less likely to rotate or tip over; the power component drives the driving wheel to steer and move, thereby realizing the movement of the carrier, so the operator can remotely control the movement of the carrier through a wireless remote control, and can more conveniently observe the status and position of the multi-petal grab, making the transportation process of the multi-petal grab more convenient; in addition, due to the low height of the base, placing the multi-petal grab on the support seat on the top of the base can lower the overall center of gravity, making the movement of the carrier more stable and reliable.

[0033] 2. During the process of lowering the multi-petal grab, the downward movement of the multi-petal grab can cause the support rod and the active rack to move downward. The driven gear rotates accordingly, and the driven gear drives the mounting cylinder to rotate, and the mounting cylinder drives the baffle to rotate until one side of the baffle is against the outside of the multi-petal grab, thereby protecting the middle and upper part of the multi-petal grab, which helps to further enhance the safety of the multi-petal grab transportation process.

[0034] 3. The abutment plate arranged on the baffle is pressed against the outer side of the multi-petal grab bucket under the action of the spring, so that the abutment plate can apply oblique downward pressure to the multi-petal grab bucket, so that the multi-petal grab bucket is further pressed against the support seat. In addition, the multi-petal grab bucket's own gravity can make the multi-petal grab bucket less likely to tip over or shake during transportation, making it safer. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The following combination Figure 1-Figure 5 This application is described in further detail.

[0042] The embodiment of the present application discloses a fully automatic wireless remote control multi-flap grab bucket carrier. In this embodiment, the carrier is used to transport a multi-flap grab bucket 10 having six jaws 101. Each jaw 101 is provided with a corresponding connecting rod 102, and the connecting rod 102 is arranged at an angle. Figure 1The fully automatic wireless remote-controlled multi-petal grab bucket carrier includes a base 1 and a driving mechanism. The base 1 is arranged horizontally, and the driving mechanism is arranged on the base 1 to drive the base 1 to move. The driving mechanism includes a driving wheel 3, a driven wheel 4 and a power assembly 5. There are two driving wheels 3 and two driven wheels 4, with the two driving wheels 3 located on one side of the base 1 and the two driven wheels 4 located on the other side of the base 1. The power assembly 5 is arranged on the base 1, and there are two groups of power assemblies 5, which correspond to the two driving wheels 3 respectively; the power assembly 5 is used to drive the driving wheels 3 to operate.

[0043] The power assembly 5 includes a first motor 51, a slewing bearing, a connecting seat 52 and a second motor 53. The first motor 51 is fixedly connected to the base 1, and the output shaft of the first motor 51 is vertically downward. The axis of the slewing bearing is vertically arranged, and the slewing bearing is connected between the first motor 51 and the connecting seat 52. The second motor 53 is fixedly connected to the connecting seat 52, and the output shaft of the second motor 53 is horizontally arranged, and the output shaft of the second motor 53 is coaxially fixedly connected to the driving wheel 3. Therefore, after the first motor 51 is started, the driving wheel 3 can be rotated around the vertical axis, thereby realizing the steering function; after the second motor 53 is started, the driving wheel 3 can be rotated around its own axis, thereby realizing the walking function. Furthermore, a reducer is provided between the first motor 51 and the slewing bearing, and between the second motor 53 and the driving wheel 3, so as to adapt to different needs.

[0044] The base 1 is also provided with a generator set 9, which can supply power to the first motor 51 and the second motor 53, enabling the first motor 51 and the second motor 53 to operate normally. A rain shield 91 is fixedly provided on the top of the generator set 9 to protect the generator set 9 and ensure the normal operation of the generator set 9. Therefore, the operator standing on the ground can control the operation of the first motor 51 and the second motor 53 through a wireless remote control, thereby driving the transport vehicle to move.

[0045] A support seat 2 is welded to the top wall of the base 1. Six support seats 2 are provided and arranged in a circular array, with each support seat 2 corresponding to a jaw plate 101 of a multi-petal grab 10. The inner side of the support seat 2 is provided with an arc surface, which adapts to the bottom end of the outer side of the jaw plate 101 of the multi-petal grab 10. Therefore, the support seat 2 can support the multi-petal grab 10 and prevent the multi-petal grab 10 from tipping over. A positioning plate 21 is welded to the inner arc surface of each support seat 2. The positioning plate 21 is perpendicular to the arc surface of the support seat 2; two positioning plates 21 are provided and arranged in a spaced-apart manner. Therefore, the positioning plates 21 can limit the jaw plate 101, thereby enhancing the stability of the multi-petal grab 10 after placement.

[0046] Reference Figure 2 、 Figure 3 and Figure 4In order to further enhance the stability of the multi-petal grab 10 placed on the support seat 2, a protective mechanism 6 is also provided on the base 1. The protective mechanism 6 is arranged on the outside of the support seat 2. The protective mechanism 6 includes a baffle 61, a mounting tube 62, a torsion spring 63 and a first drive assembly 64. There are six baffles 61 arranged in a circular array, corresponding to the six support seats 2 respectively. A mounting tube 62 is welded to the bottom end of each baffle 61, and the mounting tube 62 is a cylinder. A support rod 11 is fixedly connected to the base 1. The support rod 11 is inserted into the mounting tube 62, and the rod diameter of the support rod 11 is the same as the inner diameter of the mounting tube 62, so that the mounting tube 62 and the support rod 11 are rotatably connected. The torsion spring 63 is fixedly connected between the end of the mounting tube 62 and the support rod 11, and the torsion spring 63 plays a reset role; when the baffle 61 is set vertically, the torsion spring 63 is in an untwisted state.

[0047] The first drive assembly 64 is provided with six groups and arranged in a circular array, corresponding to the six baffles 61 respectively. The first drive assembly 64 is used to drive the baffle 61 to rotate toward the side close to the support base 2. The first drive assembly 64 includes an active rack 641, a driven gear 642 and a support rod 643. The driven gear 642 is coaxially fixedly connected to one end of the mounting tube 62; the active rack 641 is vertically arranged and slidably arranged on the base 1 along the vertical direction. The active rack 641 is meshed with the driven gear 642. The support rod 643 is welded to the bottom end of the active rack 641; the support rod 643 includes a horizontal portion 6431 and a vertical portion 6432. One end of the horizontal portion 6431 is welded to the bottom end of the active rack 641, and the vertical portion 6432 is welded to the top wall of the horizontal portion 6431 away from the end of the active rack 641.

[0048] Therefore, after the crane moves the multi-petal grab 10 above the base 1, the multi-petal grab 10 can be gradually lowered, with the bottom end of the multi-petal grab 10 first abutting against the top of the vertical portion 6432. Then, as the multi-petal grab 10 moves downward, the support rod 643 and the active rack 641 can be moved downward, the active rack 641 drives the driven gear 642 to rotate, and the driven gear 642 drives the mounting cylinder 62 to rotate, causing the baffle 61 to rotate toward the side closer to the support base 2 until the baffle 61 abuts against the outside of the multi-petal grab 10. Therefore, after the multi-petal grab 10 is placed on the support base 2, each baffle 61 can be located outside the corresponding jaw plate 101, thereby limiting the movement of the multi-petal grab 10 and improving the stability of the multi-petal grab 10 after placement.

[0049] Furthermore, a push plate 12 is provided above the vertical portion 6432 of the support rod 643. The push plate 12 is arranged horizontally, and the bottom wall of the push plate 12 and the top wall of each vertical portion 6432 are welded and fixed, so that multiple support rods 643 can be fixedly connected as a whole, so that when the multi-petal grab 10 moves downward, the push plate 12 can be pushed downward, thereby causing multiple support rods 643 to move downward synchronously, thereby improving the consistency of the baffle 61 rotation process and better protecting the multi-petal grab 10.

[0050] An abutment plate 7 is provided on the side of the baffle 61 near the support seat 2, extending along the length of the baffle 61. A guide rod 71 is welded to the abutment plate 7, which slides through the baffle 61, thereby allowing the abutment plate 7 to slide on the baffle 61. A spring 72 is fixedly connected between the abutment plate 7 and the baffle 61, and is sleeved on the outer side of the guide rod 71. The spring 72 is in a compressed state. Therefore, when the first drive assembly 64 drives the baffle 61 to rotate, the abutment plate 7 on the baffle 61 can be brought into contact with the outer wall of the connecting rod 102 on the jaw plate 101. At this time, the spring 72 is further compressed. Under the action of the spring 72, the abutment plate 7 is pressed against the outer wall of the connecting rod 102, thereby applying oblique downward pressure to the multi-petal grab 10, thereby further improving the stability of the multi-petal grab 10.

[0051] Furthermore, a guard plate 73 is vertically welded to the side of the abutment plate 7 away from the baffle 61. The guard plate 73 extends along the length of the abutment plate 7. Two guard plates 73 are provided, one on each side of the abutment plate 7. When the abutment plate 7 is pressed against the outer wall of the connecting rod 102, the two guard plates 73 are positioned on either side of the connecting rod 102, further restricting the connecting rod 102 and the jaw plate 101, thereby improving the stability of the multi-peb grab 10. In this embodiment, the spacing between the two guard plates 73 is the same as the width of the connecting rod 102. In other embodiments, the spacing between the two guard plates 73 can be greater than the width of the connecting rod 102, thereby improving the fault tolerance during operation.

[0052] Reference Figure 4, a locking mechanism 8 is provided on the base 1, and the locking mechanism 8 includes a connecting ring 81, an insert rod 82 and a second drive assembly 83. The connecting ring 81 is a circular ring, and the connecting ring 81 is sleeved on the outer side of the support seat 2; the axis of the connecting ring 81 is vertically arranged, and the connecting ring 81 rotates around its own axis and is connected to the top wall of the base 1. A connecting plate 611 is welded to each baffle 61, and the connecting plate 611 is an arc-shaped plate, and the axis of the bending direction of the connecting plate 611 is coaxial with the axis of the mounting tube 62; a first socket 6111 is provided at one end of the connecting plate 611 close to the baffle 61. The insert rod 82 is welded to the top wall of the connecting ring 81, and there are six insert rods 82 arranged in a circular array, and each insert rod 82 corresponds to a connecting plate 611. The insertion rod 82 includes a straight rod 821 and a curved rod 822. The straight rod 821 is arranged vertically, and the bottom end of the straight rod 821 is welded to the top wall of the connecting ring 81. The axis of the curved rod 822 in the bending direction is coaxial with the axis of the connecting ring 81, and one end of the curved rod 822 is welded to the top wall of the straight rod 821. Therefore, when the connecting ring 81 rotates, it drives the straight rod 821 and the curved rod 822 to rotate, allowing the curved rod 822 to be inserted into the first insertion hole 6111. When the curved rod 822 is inserted into the first insertion hole 6111, the baffle 61 is arranged at an angle, and the abutment plate 7 on one side of the baffle 61 is pressed against the outer wall of the connecting rod 102 by the action of the spring 72. The second drive assembly 83 is disposed on the base 1 and is used to drive the connecting ring 81 to rotate.

[0053] The end of the arc rod 822 away from the straight rod 821 is hemispherical, thereby making it easier for the arc rod 822 to be inserted into the first insertion hole 6111 .

[0054] Reference Figure 1 and Figure 4 The second drive assembly 83 includes a third motor 831, a driving gear 832, and a driven gear ring 833. The third motor 831 is fixedly connected to the bottom wall of the base 1, and the output shaft of the third motor 831 is vertically arranged; the driving gear 832 is coaxially fixedly connected to the output shaft of the third motor 831; the driven gear ring 833 is coaxially fixedly connected to the inner wall of the connecting ring 81, and the driven gear ring 833 and the driving gear 832 are meshed. Therefore, after the third motor 831 is started, it can drive the driving gear 832 to rotate, and the driving gear 832 drives the driven gear ring 833 to rotate, and the driven gear ring 833 drives the connecting ring 81 to rotate, so that the insertion rod 82 on the connecting ring 81 is inserted into the first socket 6111 or slides out of the first socket 6111. The insertion rod 82 inserted into the first insertion hole 6111 can limit the rotation of the connecting plate 611 and the baffle 61, thereby fixing the baffle 61 at the current position, which can further enhance the limiting protection effect of the multi-petal grab bucket 10.

[0055] Reference Figure 5A second insertion hole 6112 is provided at one end of the connecting plate 611 away from the baffle 61. When the arc rod 822 is inserted into the second insertion hole 6112, the baffle 61 is in a vertical state. Therefore, the cooperation between the second insertion hole 6112 and the insertion rod 82 can improve the stability of the baffle 61 in the vertical state.

[0056] It should be noted that the first motor 51 , the second motor 53 and the third motor 831 in this embodiment are all motors whose output shafts can be self-locking.

[0057] The operating principle of the fully automatic wireless remote-controlled multi-petal grab truck in the embodiment of the present application is as follows: wireless remote control controls the first motor 51 and the second motor 53, causing the driving wheel 3 to steer and move, thereby moving the truck to the lower side of the crane. The crane then transfers the multi-petal grab 10 to directly above the base 1. An operator standing on the ground can hold the multi-petal grab 10 with their hands and ensure that each jaw 101 of the multi-petal grab 10 is in a corresponding position with a support base 2. The crane then lowers the multi-petal grab 10, causing it to gradually move downward.

[0058] As the multi-petal grab 10 moves downward, the bottom of the multi-petal grab 10 first abuts against the push plate 12. The downward movement of the multi-petal grab 10 then causes the push plate 12 and the support rod 643 to move downward. The support rod 643 drives the active rack 641 downward, which in turn drives the driven gear 642 to rotate. The driven gear 642 drives the mounting cylinder 62 and the baffle 61 to rotate toward the side close to the multi-petal grab 10. The rotation of the baffle 61 drives the abutment plate 7 to rotate until the abutment plate 7 abuts against the connecting rod 102 on the corresponding jaw plate 101. Then, as the abutment plate 7 rotates, the spring 72 between the abutment plate 7 and the baffle 61 is further compressed until the abutment plate 7 on one side of the baffle 61 abuts against the outer side of the connecting rod 102 on the jaw plate 101. At this point, the bottom end of each jaw plate 101 of the multi-petal grab 10 abuts against the corresponding support seat 2, thereby placing the multi-petal grab 10 on the carrier.

[0059] Then the third motor 831 drives the driving gear 832 to rotate, the driving gear 832 drives the driven gear ring 833 to rotate, and the driven gear ring 833 drives the connecting ring 81 to rotate, so that the insertion rod 82 on the connecting ring 81 is inserted into the first socket 6111 on the corresponding connecting plate 611, thereby limiting the rotation of the connecting plate 611 and the baffle 61, fixing the baffle 61 in the current position, thereby further improving the stability of the multi-petal grab 10.

[0060] The carrier can then be remotely controlled again, causing the carrier to move the multi-petal grab 10 to the desired position. The output shaft of the third motor 831 then rotates in the opposite direction, causing the insertion rod 82 to slide out of the corresponding first insertion hole 6111. The crane then lifts the multi-petal grab 10 upward. During the upward movement of the multi-petal grab 10, due to the loss of the multi-petal grab 10's pressure on the push plate 12 and the support rod 643, the mounting cylinder 62, under the action of the torsion spring 63, can drive the baffle 61 to rotate away from the multi-petal grab 10 until the baffle 61 rotates to a vertical state. The rotation of the mounting cylinder 62 can also drive the driven gear 642 to rotate, causing the active rack 641 to move upward, which in turn drives the support rod 643 to move upward, causing the support rod 643 and the push plate 12 to return to their initial state, facilitating subsequent work.

[0061] The above are optional embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
