[0037] The embodiment of the utility model provides a gripper assembly and a logistics loading and unloading device model, in which all grippers synchronously grab both sides of a container, can simulate the loading and unloading process of the container, have a stable structure, can be demonstrated repeatedly, and have reduced costs.

[0038] Combine the following Figure 1-Figure 7 The technical solution provided by the utility model is described in more detail.

[0039] Embodiment 1:

[0040] The utility model provides a gripper assembly, comprising a frame 1, a rotating wheel 2, a traction part 3, and at least two groups of gripping clamps 4, wherein: the rotating wheel 2 is rotatably connected to the frame 1, and the two groups of gripping clamps 4 are respectively located on opposite sides of the frame 1, and are used to grip or release opposite sides of the loading and unloading equipment; the gripping clamps 4 are connected to the gripping clamps 4 through the corresponding traction parts 3, and all the traction parts 3 are connected to the opposite sides of the rotating wheel 2. When the rotating wheel 2 rotates forward, the traction part 3 can be wound around so that all the gripping clamps 4 are in a gripping state, and when the rotating wheel 2 rotates reversely, the traction part 3 can be released so that all the gripping clamps 4 are in an open state.

[0041] The rotating wheel 2 can be driven to rotate by a driving device such as a motor. Figure 1 As shown, the "claw 4" is a hook-like structure used to hook the equipment to be loaded and unloaded. In this embodiment, the container 8 model is used as an example of the equipment to be loaded and unloaded. The gripper assembly is used to simulate the port logistics loading and unloading device. The model only needs to simulate its function and keep the appearance consistent with the actual device.

[0042] In the gripper assembly of this embodiment, when the wheel 2 rotates forward, the traction part 3 is wound so that all the gripping clamps 4 are in a gripping state, and when the wheel 2 rotates reversely, the traction part 3 is released so that all the gripping clamps 4 are in an open state. The driving structure is simple; all the gripping clamps 4 are gripped or released synchronously, and all the gripping clamps 4 grip both sides of the container 8 synchronously, which can simulate the loading and unloading process of the container 8, has a stable structure, can be demonstrated repeatedly, and has reduced costs.

[0043] As an optional implementation, combining Figure 3 and Figure 4 As shown, each group of grippers 4 includes a first gripper 41, a second gripper 42, a third gripper 43 and a fourth gripper 44, wherein: the first gripper 41, the second gripper 42, the third gripper 43 and the fourth gripper 44 are used to grip two end corners on one side of the equipment to be loaded and unloaded; all traction parts 3 connected to the first gripper 41, the second gripper 42, the third gripper 43 and the fourth gripper 44 are connected and formed into a strand, and are fixed to the same part of the rotating wheel 2.

[0044] In this embodiment, two groups of grippers 4 are arranged on the frame 1, and each group of grippers 4 includes a first gripper 41, a second gripper 42, a third gripper 43 and a fourth gripper 44. The eight grippers 4 are grasped or opened synchronously. When the eight grippers 4 are grasped synchronously, the four end corners of the container 8 can be hooked, thereby lifting the container 8 or driving the container 8 to descend. The above structure is simple, does not require multiple driving devices, reduces costs, and has a compact structure.

[0045] As an alternative embodiment, see Figure 5As shown, at least three reversing wheels 5 are provided at one end of the frame 1, and at least part of the traction part 3 is wound on the reversing wheel 5, so as to change the traction direction and further connect with the other traction parts 3 of the same group.

[0046] See also Figure 5 As shown, the structure of the above-mentioned reversing wheel 5 can merge all the traction parts 3 in the same group of grippers 4 into one, so that all the traction parts 3 in the same group of grippers 4 are fixedly connected to the same part of the rotating wheel 2, which is convenient for the rotating wheel 2 to wind or release the traction part 3 when rotating.

[0047] See also Figure 5 As shown, a wire guide groove 9 is also provided on the frame 1, and the wire guide groove 9 serves to guide the direction of the wire. Figure 5 The structure of the lead groove 9 is omitted on the right side of the figure, and the structure of the lead groove 9 is shown on the left side.

[0048] As an alternative embodiment, see Figure 5-Figure 7 As shown, the two traction parts 3 are respectively fixed on opposite sides of the rotating wheel 2. With such an arrangement, it is possible to wind up all the traction parts 3 or release all the traction parts 3 simultaneously when the rotating wheel 2 rotates. When the rotating wheel 2 rotates forward, the traction parts 3 can be wound up so that all the gripping clamps 4 are in a gripping state. When the rotating wheel 2 rotates reversely, the traction parts 3 can be released so that all the gripping clamps 4 are in an open state.

[0049] The traction part 3 may be a rope structure such as a steel wire rope to ensure structural strength.

[0050] As an alternative embodiment, see Figure 4-Figure 7 As shown, the frame 1 is provided with a first limit block 61 and a second limit block 62, and the first baffle 21 and the second baffle 22 are fixedly connected to the opposite sides of the rotating wheel 2, wherein: Figure 6 When the rotating wheel 2 rotates forward to the position where the first baffle 21 abuts against the first limit block 61, it can wind up the traction part 3 so that all the gripping clamps 4 are in a gripping state; see Figure 7 When the rotating wheel 2 rotates in the opposite direction to the position where the second blocking piece 22 abuts against the second limiting block 62, the traction part 3 can be released so that all the gripping clamps 4 are in an open state.

[0051] The cooperation structure of the first baffle 21 and the first limit block 61 can limit the angle of the positive rotation of the rotating wheel 2, and the cooperation structure of the second baffle 22 and the second limit block 62 can limit the angle of the reverse rotation of the rotating wheel 2.

[0052] After testing, the gripper is relatively stable when the wheel 2 rotates forward or backward by 40-45 degrees. Preferably, the gripper is most stable when the wheel 2 rotates forward or backward by 42 degrees. If the angle is greater than the above, the gripper 8 is unstable; if the angle is less than the above, the gripper 4 cannot be fastened to the groove of the container 8. According to the angle, the control wheel controls the scaling amount of the traction part 3, thereby controlling the gripping angle of the gripper 4.

[0053] As an alternative embodiment, see Figure 1 As shown, the gripper 4 includes a gripper body 401, a rotating shaft 402 and an elastic portion 403. The gripper body 401 is rotatably connected to the frame body 1 via the rotating shaft 402. When the rotating wheel 2 pulls or releases the traction portion 3, the gripper body 401 rotates around the rotating shaft 402. One end of the elastic portion 403 is fixedly arranged, and the other end is abutted against the gripper body 401. The elastic portion 403 is used to drive the gripper body 401 to open when the traction portion 3 is in a released state.

[0054] When the traction part 3 is pulled by the rotating wheel 2, the traction part 3 pulls the clamp body 401 to rotate around the rotating shaft 402. When the clamp body 401 grabs, the elastic part 403 is pulled to stretch; when the traction part 3 is released by the rotating wheel 2, the elastic restoring force of the elastic part 403 drives the clamp body 401 to open. The elastic part 403 can be a torsion spring, one of the force arms of the torsion spring is fixedly arranged, and the other force arm is against the clamp body 401.

[0055] As an alternative embodiment, see Figure 1-Figure 4 As shown, the gripper assembly also includes a lifting mechanism, which includes a hinge 71, a sprocket 72 and a driving device, wherein: the sprocket 72 is connected to the frame 1, the hinge 71 is meshed with the sprocket 72 for transmission, and the output end of the driving device is connected to the hinge 71 for transmission, and can wind or release the hinge 71, thereby driving the frame 1 to rise and fall. The driving device can be a motor, and a driving wheel is provided on the output end of the motor, and the driving wheel is used to wind or release the sprocket 72, thereby driving the frame 1 to rise and fall through the sprocket 72.

[0056] As an alternative embodiment, see Figure 1 As shown, the frame 1 is provided with a limit groove 11, the limit groove 11 is vertically arranged, and the hinge 71 is slidably connected to the limit groove 11. The sprocket 72 can be slidably connected to the limit groove 11 through a slider, thereby limiting the vertical lifting of the sprocket 72.

[0057] When the hinge 71 is in a fully stretched state (tightened), the sprocket 72 is pulled to the top of the limiting groove 11; but when the driving device (motor) stops running and the hinge 71 is in a relaxed state, the sprocket 72 cannot be completely retracted to the bottom of the limiting groove 11, which causes a part of the hinge 71 to rest on the sprocket 72, causing wear between the hinge 71 and the sprocket 72 and bending of the chain.

[0058] For the above questions, see Figure 1-Figure 3 As shown, a return spring 73 is fixed on the frame 1, one end of the return spring 73 is a fixed end, and the other end is fixedly connected to the sprocket 72. The return spring 73 can extend when the hinge 71 is in a wound state, and can retract when the hinge 71 is in a released state, thereby tightening the hinge 71.

[0059] The function of the return spring 73 in this embodiment is to keep the hinge 71 in a tensioned state at all times, to prevent wear between the hinge 71 and the sprocket 72 and bending of the chain, and to prevent the hinge 71 from being misaligned.

[0060] In the gripper 4 assembly of this embodiment, the rotating wheel 2 drives the traction part 3 to rotate around the wheel. When the rotating wheel 2 rotates forward, the traction part 3 is wound and tightened, and the limit transmission signal is cut off, that is, the first limit block 61 abuts against the first baffle, and the gripper 4 is tightened at the same time to firmly lock the container 8. When the rotating wheel 2 rotates reversely, the first limit block 61 abuts against the first baffle, the rotating wheel 2 releases the traction part 3, and the elastic part 403 bounces the gripper body 401, and the gripper body 401 opens to release the container 8. The above process can be repeatedly demonstrated.

[0061] Embodiment 2:

[0062] This embodiment provides a logistics loading and unloading device model, including the above-mentioned gripper assembly.

[0063] The logistics loading and unloading device model of this embodiment can simulate the loading and unloading process of the container 8, has a stable structure, can be demonstrated repeatedly, and has low cost.
