Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0034] Embodiment 1: When a lighter object needs to be transported,

[0035] Reference Figure 1-3 As shown, a convenient mechanical grabbing lifting and transporting vehicle comprises

[0036] Support pole column 1;

[0037] The mobile structure 6 is used to drive the lifting and transporting vehicle to move forward and backward;

[0038] The first pivot seat 2 is arranged at the top of the support pole column 1 and is used to connect the lever arm 3, and the lever arm 3 moves up and down through the first pivot seat 2; one end of the lever arm 3 is provided with a connecting hanger 5 for connecting with the first clamping structure 7, and the other end of the lever arm 3 is provided with a handle 4.

[0039] The first gripping structure 7 is arranged at one end of the lever arm 3 and is used for gripping and fixing objects. The first gripping structure 7 includes a triangular main rod 70, and the two ends of the triangular main rod 70 are respectively pivoted with a first movable rod 71 and a second movable rod 72, and the first movable rod 71 and the second movable rod 72 are respectively connected to the first suspension rod 74 and the second suspension rod 76 through the first pivot rod 73 and the second pivot rod 75. A cross plate 77 is provided between the first suspension rod 74 and the second suspension rod 76, and a movable groove 78 is provided on the cross plate 77. A connecting rod 79 is installed in the movable groove 78, and the second suspension rod 76 and the cross plate 77 are connected, so that the second suspension rod 76 and the connecting rod 79 can slide left and right in the movable groove 78, and control the opening and closing of the clamping jaws 710 to clamp the object.

[0040] A hook piece 711 is disposed at one end of the clamping jaw 710 , and a positioning rod 712 is disposed on the outer wall of one end of the hook piece 711 .

[0041] A vertical rod 713 is arranged between the two triangular main rods 70, and a hook 714 is arranged at one end of the vertical rod 713; a mounting plate 715 is arranged between the two second movable rods 72, a hanging ring 716 is arranged at the top of the mounting plate 715, and an auxiliary block 717 is arranged on one side of the mounting plate 715; when the first movable rod 71 and the second movable rod 72 are forced to move downward, the second movable rod 72 contacts the top surface of the object, thereby pushing the hook 714 out of the hanging ring 716, releasing the second movable rod 72 and the first movable rod 71.

[0042] When it is necessary to grasp an object, one end of the arm 3, i.e., the first grasping structure 7, starts to work through the first movable rod 71 and the second movable rod 72 pivoted at both ends of the triangular main rod 70. The two movable rods are connected to the first suspension rod 74 and the second suspension rod 76 through the first pivot rod 73 to form a grasping mechanism that can be opened and closed. As the first suspension rod 74 and the second suspension rod 76 move, the connecting rod 79 in the movable groove 78 on the horizontal plate 77 also slides. This action directly controls the opening and closing of the clamping claw 710, thereby realizing the grasping of the object. The design of the clamping claw 710 is also ingenious. The curved hook piece at one end thereof 711 and the positioning rod 712 on the outer wall not only enhance the stability of grasping, but also provide precise positioning. During the grasping process, the vertical rod 713 between the two triangular main rods 70 and the hook 714 at one end thereof play a key role. When the first movable rod 71 and the second movable rod 72 are subjected to a downward force, the second movable rod 72 contacts the top surface of the object. This force causes the hook 714 to be ejected from the hanging ring 716, thereby releasing the first movable rod 71 and the second movable rod 72, so that the grasping structure can be opened and the object can be released, thereby achieving efficient and stable grasping and releasing actions.

[0043] The positioning structure 8 includes a pedal 80, a rocking plate 81 arranged at one end of the pedal 80, a positioning plate 83 inserted into the pedal 80, and a third pivot rod 82 arranged on a side of the rocking plate 81. The third pivot rod 82 passes through the slot in the support column 1 so that the rocking plate 81 and the pedal 80 can move up and down. The positioning structure 8 also includes a second pivot seat 84, a receiving plate 85 arranged on the second pivot seat 84, a limiting plate 86 arranged on the lower end surface of the second pivot seat 84, a limiting rod 87 arranged on the limiting plate 86, and an insertion rod 88 arranged at one end of the limiting plate 86. The insertion rod 88 is connected to the socket formed on the rocking plate 81 to prevent the rocking plate 81 from falling rapidly.

[0044] When the shovel board 92 scoops up a lighter object, the object falls on the shovel board 92. Since the receiving plate 85 is provided to support the rocking plate 81 connected to the shovel board 92, the shovel board 92 can be kept at a certain height from the ground. Subsequently, the staff steps on the pedal 80 to lift the rocking plate 81 upward through the third pivot rod 82 (lever principle), and then inserts the positioning plate 83 into the support column 1 to fix the shovel board 92. After the fixation is completed, the first pivot seat 2 is used to drive the force arm 3 to loosen the first clamping structure 7 downward until the first clamping structure 7 contacts the object. When the first clamping structure 7 contacts the object, After the object contacts, the hook 714 is pushed out from the hanging ring 716, thereby releasing the first movable rod 71 and the second movable rod 72, so that the clamping jaw 710 can be unfolded outward. After unfolding, the force arm 3 is lifted upward. At this time, the clamping jaw 710 gradually moves toward the shovel plate 92 until the hook member 711 fits the edge of the shovel plate 92, and then the force arm 3 is lifted upward to a height, so that the several holes and grooves symmetrically arranged on both sides of the bottom of the shovel plate 92 are plugged into the positioning rod 712 on the hook member 711, so that the clamping jaw 710 is fixed to the shovel plate 92, and the clamping jaw 710 can better wrap the object. In summary, the cooperation between the shovel plate 92 and the clamping jaw 710 can better transfer and stack lighter objects, which is more labor-saving, and can also prevent the bagged objects from being damaged, which is conducive to ensuring the integrity of the objects.

[0045] This embodiment further includes a shovel structure for handling objects in water, referring to Figure 4-5 ,

[0046] It includes a first inclined frame plate 90, a shovel plate 92 connected to the first inclined frame plate 90, the object is lifted by the shovel plate 92, and then the shovel plate 92 is clamped and wrapped by the clamping claw 710 to fix the object, and moved back and forth through the moving structure 6; the shovel plate 92 includes an inclined portion 93; a first micro motor 94 is arranged on one side of the shovel plate 92, a second inclined frame plate 95 connected to the first micro motor 94, hollow grooves 96 are arranged on the shovel plate 92 at equal intervals, and a reinforcing plate 97 is arranged at the bottom of the shovel plate 92; wherein the first micro motor 94 drives the second inclined frame plate 95 to fold upward, so that the shovel plate 92 changes to the second form.

[0047] Among them, when the object to be transferred is in a puddle, the second inclined frame plate 95 is rotated and folded upward (second form) through the first micro motor 94, so that the hollow groove 96 on the shovel plate 92 is exposed, so that when shoveling objects, water on the objects can flow out from the hollow groove 96, avoiding affecting the weighing capacity of the shovel plate 92 due to excessive weight of the object. Furthermore, in order to fix the object, when the object is already on the shovel plate 92, the first micro motor 94 is turned on, and the first micro motor 94 drives the second inclined frame plate 95 to press down towards the object, thereby clamping the object, thereby further ensuring that the object will not move during transportation.

[0048] Furthermore, there is an angle A between the shovel plate 92 and the first inclined frame plate 90, and the angle A is 100°≤A≤160°. In order to ensure that the object can be just between the shovel plate 92 and the first inclined frame plate 90, in one embodiment, the angle A is about 145°. The advantage of such a setting is that it is easy to concentrate the object, and when the angle A is too small, the shovel plate 92 may not fit the ground, so that the object cannot be shoveled.

[0049] Embodiment 2

[0050] When clamping an irregular object, the present embodiment is different from the first embodiment in that, referring to the attached Fig.10 , a convenient mechanical grabbing crane transport vehicle

[0051] The second gripping structure 10 includes a hanging plate 100, a hanging groove 101 formed at one end of the hanging plate 100, a connecting wing plate 102 symmetrically arranged between the two hanging plates 100, a first gripping arm 103 arranged at one end of the connecting wing plate 102, a fourth pivot rod 104 and a fifth pivot rod 106 arranged on the first gripping arm 103, and an eighth pivot rod 114 arranged at one end of the first gripping arm 103; wherein the fifth pivot rod 106 connects the connecting wing plate 102 and the first gripping arm 103;

[0052] An electric push rod 121 is disposed between the two connecting plates 100 , and a push plate 122 is disposed at one end of the electric push rod 121 . The push plate 122 is movably connected to the first clamping arm 103 , so that the first clamping arm 103 can be driven to move left and right through the electric push rod 121 .

[0053] The first gripping arm 103 has connecting plates 107 symmetrically disposed on both sides of the clamping end, a sixth pivot rod 109 disposed between the two connecting plates 107, a support rod 108 rotatably disposed on the sixth pivot rod 109, and a moving wheel 110 disposed at one end of the support rod 108; a third pivot seat 111 is disposed on one side of the support rod 108, a seventh pivot rod 113 disposed at one end of the third pivot seat 111, and a movable telescopic rod 112 disposed at one end of the seventh pivot rod 113, and the movable telescopic rod 112 penetrates The eighth pivot rod 114 is movably connected to the ninth pivot rod 117, and the protruding end of the movable telescopic rod 112 is provided with a connecting rope 118 for connecting the two clamping members; wherein, the two clamping members are rotatably arranged on the ninth pivot rod 117, and one of the clamping members includes a second clamping arm 115 and a third clamping arm 116, a second micro motor 119 is arranged between the second clamping arm 115 and the third clamping arm 116, and a threaded rubber pad 120 is arranged at one end of the third clamping arm 116.

[0054] The material of the connecting rope 118 is steel, nylon, polyester or carbon fiber. In one embodiment, preferably, the material of the connecting rope 118 is nylon, which has high wear resistance and tensile strength and is light in weight.

[0055] When it is necessary to grasp an object, the electric push rod 121 is extended and retracted, driving the push plate 122 and the first gripping arm 103 to move left and right, thereby realizing the preliminary grasping of the object. Subsequently, after the first gripping arm 103 is opened and closed, as the first gripping arm 103 gradually approaches the object below, the moving wheel 110 contacts the ground and expands outwards. At the same time, the movable telescopic rod 112 on the third pivot seat 111 and the seventh pivot rod 113 drives the gripping member to expand outwards through the connecting rope 118, thereby expanding the gripping angle of the gripping member. When the gripping member contacts the object, the second gripping arm 103 is used to move the gripping member outwards. The micro motor 119 drives the second gripping arm 115 and the third gripping arm 116 to open and close, further adjusting the opening and closing degree of the gripping member to ensure that the object is firmly grasped. After the initial fixation is completed, the electric push rod 121 retracts, and the moving wheel 110 gradually moves toward the gripping member. After the electric push rod 121 retracts, it will further apply a clamping force to the object to ensure that the object will not move, especially when facing various irregular shaped objects, it can be effectively fixed. In addition, the threaded rubber pad 120 can provide additional friction and protection during the grasping process to prevent the object from slipping or being damaged. During the whole process, the setting of each pivot rod and connecting plate ensures the stability and flexibility of the gripping structure, so that the second gripping structure 10 can efficiently and stably complete the task of grasping and fixing objects.

[0056] This embodiment also includes a convenient mechanical clamping control method, the steps are as follows:

[0057] S1, initialization preparation, ensuring that all components are in the initial position, the electric push rod 121 is not activated, and the first gripping arm 103 is in a closed state;

[0058] S2, start the electric push rod 121, the push plate 122 is movably connected with the first gripping arm 103, and drives the first gripping arm 103 to move left and right, ready to grab the object;

[0059] S3, the electric push rod 121 continues to extend and retract, pushing the first gripping arm 103 to open, thereby achieving preliminary gripping of the object;

[0060] S4. As the first gripping arm 103 opens and closes, the moving wheel 110 contacts the ground and expands outward, increasing the stability of the gripping structure;

[0061] S5, the movable telescopic rod 112 drives the two gripping members to expand outwards through the connecting rope 118, thereby expanding the gripping angle to adapt to the shape of the irregular object;

[0062] S6, driving the second gripping arm 115 and the third gripping arm 116 to open and close through the second micro motor 119, further adjusting the degree of opening and closing of the gripping member to ensure that the object is firmly grasped;

[0063] S7, after the initial fixation is completed, the electric push rod 121 retracts, and the moving wheel 110 gradually moves toward the gripping member to increase the clamping force and ensure that the object does not move;

[0064] S8, threaded rubber pad 120 provides additional friction and protection during the grasping process to prevent the object from slipping or being damaged;

[0065] S9. The arrangement of all the pivot rods and connecting plates ensures the stability and flexibility of the gripping structure, thereby completing the gripping and fixing of the object;

[0066] S10, after the object is firmly grasped, the lifting and transporting vehicle can move forward and backward through the moving structure 6 to transport the object to a designated location;

[0067] S11, after reaching the destination, the electric push rod 121 and the second micro motor 119 are operated in reverse to open the gripper and release the object.

[0068] In step S6, an angle adaptive control method is further included:

[0069] Angle adaptive control methods include:

[0070] S60, an angle sensor and a force sensor (existing technology) are integrated at the base or connection of the second gripping arm 115 and the third gripping arm 116, and these sensors monitor the angle of the gripping arm and the force applied to the object in real time, and the data fed back by the angle sensor and the force sensor are transmitted to the intelligent control system and the adaptive algorithm (in the field of mechanical arms and robotics, the combination of these sensors and micro motors can achieve precise control of the movement of the mechanical arms, including the adjustment of the angle and force, for this reason, this case will not be described in detail), thereby automatically adjusting the output of the second micro motor 119 to change the angle between the second gripping arm 115 and the third gripping arm 116, so as to better adapt to the shape of irregular objects.

[0071] In summary, the adaptability of the gripper to irregular objects can be improved, ensuring a more stable and safer grip, while also reducing damage to objects and improving handling efficiency. In this way, the introduction of the angle adaptive mechanism can significantly improve the performance of the lifting and transporting vehicle when handling complex handling tasks.
