Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] like Figure 1 As shown, an embodiment of the present invention provides a handling device, which comprises: a base 10, a support base 20, a rotating base 30, and a clamping assembly 40. The base 10 has wheels; the support base 20 is fixedly arranged on the base 10; the rotating base 30 is rotatably arranged on the base 10. Along the direction of travel of the handling device, the rotating base 30 is located at the rear side of the support base 20. The rotating base 30 can swing in the front and rear directions relative to the support base 20. The rotating base 30 has a rotating state and a locking state set relative to the support base 20. A handle 31 is arranged at one end of the rotating base 30 away from the base 10. The clamping assembly 40 is arranged at a side of the support base 20 away from the rotating base 30. The clamping assembly 40 is used to clamp goods. The rotating base 30 is drivingly connected to the clamping assembly 40. When the rotating base 30 is in the rotating state, it can drive the clamping assembly 40 to clamp or release the goods. When the clamping assembly 40 clamps the goods, the rotating base 30 switches to the locking state to fix the position of the clamping assembly 40 on the support base 20.

[0047] By applying the technical solution of the present invention, the rotating seat 30 is first switched to the rotating state, and the rotating seat 30 is rotated in a direction away from the support seat 20 by the handle 31 on the rotating seat 30 to drive the clamping assembly 40 on the support seat 20 to clamp the goods, and then the rotating seat 30 is switched to the locking state to fix the position of the clamping assembly 40 on the support seat 20 to prevent the goods from falling due to the loosening of the clamping assembly 40. Through the above settings, the rotating seat 30 is set to the rotating state and the locking state, so that the handling device clamps the goods more safely and reliably, and the handling device has a simple structure and is convenient for the staff to operate, which can improve the handling efficiency and reduce the handling cost.

[0048] Specifically, in the embodiments of the present application, Figure 1 As shown, the direction of the X-axis is the forward direction of the transport device, and the bottom end of the rotating seat 30 rotates around the Y-axis to make the top end of the rotating seat 30 close to or away from the support seat 20. The Y-axis is the width direction of the transport device.

[0049] Further, the support seat 20 is provided with a support shaft 21, and the clamping assembly 40 includes two clamping jaws 41, the middle parts of the two clamping jaws 41 are rotatably connected to the support shaft 21, the two clamping jaws 41 have a first end 411 and a second end 412 arranged opposite to each other, the first ends 411 of the two clamping jaws 41 extend in a direction away from the support seat 20, the first ends 411 of the two clamping jaws 41 cooperate with each other to clamp the goods, and the rotating seat 30 is drivingly connected with the second ends 412 of the two clamping jaws 41. Through the above arrangement, the middle parts of the two clamping jaws 41 are rotatably connected to the support shaft 21, so that the two clamping jaws 41 form a scissor cross shape to facilitate the cooperation in clamping the goods. The rotating seat 30 indirectly controls the first ends 411 of the two clamping jaws 41 to cooperate with each other to clamp the goods by driving the second ends 412 of the two clamping jaws 41, which has a simple structure, is convenient for the staff to operate, and is conducive to improving the handling efficiency.

[0050] In the embodiment of the present application, two horizontal plates are fixedly arranged on the support seat 20, and the two horizontal plates are spaced a distance apart, and the support shaft 21 is fixedly arranged between the two horizontal plates. In addition, a rubber anti-slip pad can be added to the clamping groove inside the clamping jaw 41 to increase the friction between the clamping jaw 41 and the goods and enhance the clamping effect.

[0051] Specifically, a movable seat 50 is movably provided on the support seat 20, and the movable seat 50 moves in the front-back direction. A connecting shaft 51 is fixed on the movable seat 50, and the connecting shaft 51 is arranged parallel to the support shaft 21. The clamping assembly 40 also includes two connecting rods 42, one end of the two connecting rods 42 is respectively hinged to the connecting shaft 51, and the other end of the two connecting rods 42 is hinged to the second end 412 of the two clamping claws 41 in a one-to-one correspondence, and the rotating seat 30 is drivingly connected to the movable seat 50. Among them, in the embodiment of the present application, the movable seat 50 is arranged on two horizontal plates on the support seat 20, and there are sliding grooves corresponding to the movable seat 50 on the two horizontal plates, so that the movable seat 50 can be slidably arranged on the two horizontal plates of the support seat 20.

[0052] In the embodiments of the present application, Figure 1 As shown, one end of the two connecting rods 42 is hinged to the connecting shaft 51 respectively, and the other end of the two connecting rods 42 is hinged to the second ends 412 of the two clamping jaws 41 in a one-to-one correspondence, so that when the connecting shaft 51 moves, the connecting rods 42 are driven to rotate, thereby driving the second ends 412 of the clamping jaws 41 to rotate, so that the angle between the two connecting rods 42 and the second ends 412 of the clamping jaws 41 increases, and the first ends 411 of the two clamping jaws 41 cooperate with each other to clamp the goods.

[0053] Furthermore, the handling device includes a plurality of groups of clamping assemblies 40, which are spaced apart along the extension direction of the support seat 20. Through the above arrangement, the plurality of groups of clamping assemblies 40 can be adjusted according to different shapes and sizes of goods, and can achieve a better clamping effect on the goods, improve the stability and safety of the device, and in addition, the plurality of groups of clamping assemblies can achieve accurate clamping of the goods, avoiding damage to the goods and injuries to the staff caused by improper clamping.

[0054] like Figure 2 and Figure 3 As shown, the transport device further includes a guide assembly 60, which is disposed between the support seat 20 and the rotating seat 30, and is used to guide the swing of the rotating seat 30. Through the above arrangement, the guide assembly 60 is used to guide the swing of the rotating seat 30, so that the rotating seat 30 can swing accurately according to the track set by the guide assembly 60, reduce deviation and vibration, ensure the smooth swing of the rotating seat 30, and improve the stability of the entire device.

[0055] Specifically, the guide assembly 60 includes a guide rail 61 and a guide member 62. The guide rail 61 is arranged on a side of the support seat 20 close to the rotating seat 30, and the extension direction of the guide rail 61 is the same as the swing direction of the rotating seat 30; the guide member 62 is movably arranged on the guide rail 61, and the guide member 62 is fixedly connected to the rotating seat 30, and the guide rail 61 and the guide member 62 cooperate to guide the rotating seat 30. The guide rail 61 is arranged in an arc shape, which is adapted to the arc track when the rotating seat 30 rotates toward and away from the support seat 20, and the guide member 62 moves on the guide rail 61, so that the rotating seat 30 can be smoothly swung to a suitable position, which is convenient for the clamping assembly 40 to clamp the goods.

[0056] In the embodiments of the present application, Figure 3 As shown, a connecting block 52 is provided at the bottom of the moving seat 50 and in the through hole 22 of the supporting seat 20, and a pull rope 53 is provided on the connecting block. The two ends of the pull rope 53 are tied and fixed, and the rope ring formed by the pull rope is sleeved on the connecting block 52 and the guide member 62. In addition, the pull rope 53 in the embodiment of the present application is a steel wire rope, which has high strength and is not easy to break, which is conducive to improving the stability of the device.

[0057] When the handle 31 is used to rotate the rotating seat 30 toward the side away from the support seat 20, the guide member 62 fixedly arranged on the rotating seat 30 slides on the guide rail 61. At this time, the pull rope 53 on the guide member 62 pulls the movable seat 50 through the connecting block 52 fixed on the movable seat 50, so that it slides in the slide grooves of the two horizontal plates on the support seat 20, so that the connecting shaft 51 on the movable seat 50 moves in the direction close to the support seat 20. One end of the two connecting rods 42 of the clamping assembly 40 moves along with the connecting shaft 51, driving the two connecting rods 42 to rotate. Since the other ends of the two connecting rods 42 are hinged to the second ends 412 of the two clamping claws 41 in a one-to-one correspondence, the second ends 412 of the clamping claws 41 are driven to rotate. Since the middle parts of the two clamping claws 41 are rotatably connected to the support shaft 21 and the support shaft 21 is fixed on the support seat 20, the angle between the two connecting rods 42 and the second ends 412 of the clamping claws 41 increases, and the first ends 411 of the two clamping claws 41 cooperate with each other to clamp the goods.

[0058] like Figure 4 As shown, the handling device further includes a locking structure 70, which is disposed between the guide rail 61 and the guide member 62, and is used to unlock and lock the position of the guide member 62 on the guide rail 61. Through the above arrangement, when the locking structure 70 is in an unlocked state, the guide member 62 can move on the guide rail 61, so that the rotating seat 30 can smoothly rotate to a suitable position, thereby facilitating driving the clamping assembly 40 to clamp the goods. When the locking structure 70 is in a locked state, the guide member 62 is fixed on the guide rail 61, so that the rotating seat 30 can be fixed to a suitable position, so that the clamping assembly 40 can continue to clamp the goods, thereby improving the safety and reliability of the device.

[0059] Furthermore, the guide member 62 has a threaded section, and the locking structure 70 includes a locking nut 71 and a limiting groove 72. The limiting groove 72 is provided at the end of the guide rail 61, and the locking nut 71 is threadedly connected with the threaded section to fix the guide member 62 in the limiting groove 72. Through the above arrangement, after the clamping assembly 40 is controlled to clamp the cargo, the locking nut 71 can be threadedly connected with the threaded section of the guide member 62 to fix the guide member 62 in the limiting groove 72 of the guide rail 61, ensuring that the guide member 62 is stably fixed in the limiting groove 72 of the guide rail 61.

[0060] Specifically, the guide assembly 60 includes two guide rails 61, which are arranged at intervals along the width direction of the support seat 20, and the guide member 62 is arranged on the two guide rails 61. The guide member 62 is provided with two limiting protrusions 621, and the two limiting protrusions 621 are located between the two guide rails 61. The two limiting protrusions 621 are used to limit the displacement of the guide member 62 in the width direction. Through the above arrangement, the guide rail 61 is provided in two, and the guide member 62 is arranged in the two guide rails 61 arranged at intervals along the width direction of the support seat 20, so that the guide member 62 can stably move in the two guide rails 61, thereby improving the safety of the device. In addition, the guide member 62 is provided with two limiting protrusions 621, which can limit the displacement of the guide member 62 in the width direction and prevent one end of the guide member 62 from sliding out of the guide rail 61.

[0061] In the embodiment of the present application, a notch 32 is further provided on the rotating seat 30. When the rotating seat 30 rotates close to the supporting seat 20, the two guide rails 61 pass through the two notches 32. Through the above arrangement, when the rotating seat 30 rotates, the rotating seat 30 and the two guide rails 61 fixedly provided on the supporting seat 20 can be prevented from interfering with each other, thereby improving the feasibility and safety of the transport device.

[0062] Further, if Figure 1 As shown, the base 10 is also provided with a pedal pressure plate 80, which is located on the side of the rotating base 30 away from the supporting base 20. The pedal pressure plate 80 can be used after the locking nut 71 fixes the guide member 62 in the limit groove 72 of the guide rail 61, so that the staff can shift the center of gravity of the goods with less force, reduce the labor intensity, facilitate the staff to push the handling device to move, and improve the handling efficiency. In addition, adjusting the center of gravity of the goods can ensure that the goods remain stable during the handling process, and reduce the overturning or damage of the goods caused by the unstable center of gravity.

[0063] The working process of the handling device of the present application is as follows: the staff member uses the handle 31 to rotate the rotating seat 30 to the side away from the support seat 20. At this time, the guide member 62 also slides on the guide rail 61 to the side away from the support seat 20, and the pull rope 53 on the guide member 62 pulls the movable seat 50 through the connecting block fixed on the movable seat 50, so that it slides in the slide grooves of the two horizontal plates on the support seat 20 to the side close to the support seat 20, so that the connecting shaft 51 on the movable seat 50 moves in the direction close to the support seat 20, and one end of the two connecting rods 42 of the clamping assembly 40 moves with the connecting shaft 51. Since the middle parts of the two clamping claws 41 are rotatably connected to the support shaft 21 and the support shaft 2 1 is fixed on the support base 20, so that the angle between the two connecting rods 42 and the second end 412 of the clamping claw 41 is increased, thereby reducing the angle between the first ends 411 of the two clamping claws 41, so that the clamping assembly 40 clamps the goods. After clamping the goods, the locking nut 71 is threadedly connected with the threaded section of the guide member 62 and set in the limiting groove 72 fixed on the guide rail 61, ensuring that the guide member 62 is stably fixed in the limiting groove 72 of the guide rail 61, ensuring that the two clamping claws 41 will not loosen after clamping the goods. Finally, the staff adjusts the center of gravity of the goods by stepping on the pressure plate 80, so that the goods and the support base 20 are laid flat or tilted as a whole, ensuring that the goods remain stable during the transportation process.
