During the clamping, if two groups of claws are simultaneously sleeved on the electric pole, the piston rod is compressed to drive the two piston heads to move toward the first connecting end, and at the same time, the third chamber and the fourth chamber are pressurized through the air pipe to ensure stable clamping of the claws. When one group of claws is sleeved on the electric pole, one of the piston rods is compressed, and the pressure in the first and second chambers increases and is greater than the air pressure in the third chamber, so that the other piston rod is in an extended state. At this time, the other group of claws is in an open state, and the angle of the mounting seat is adjusted to make the other group of claws sleeved on the electric pole. The other piston rod is compressed to drive the claws to close and clamp the electric pole, and finally the third chamber and the fourth chamber are pressurized through the air pipe to make the two groups of claws in a clamped state. This scheme avoids the problem of one group of claws being empty when the electric pole and the claws are not vertical, and the four-bar linkage can adjust the position and the angle of the claws at the same time.

DETAILED DESCRIPTION

[0035] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are only illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention. Example

[0036] Mechanical gripper module for pole grabbing and pole erection, such as Figure 3-9 As shown, including:

[0037] The mounting seat body 80 has a first connecting end and a second connecting end, wherein the first connecting end is used for connection and installation, and two communicating piston chambers 802 are provided inside the first connecting end;

[0038] The piston rod 801 includes two of them. Preferably, a pressure sensor can be provided at the end of the piston rod 801 to feedback the pressure value. The pressure value has two functions. One is to judge whether the clamping jaws 701 on both sides are in a clampable position. Only when the difference in the pressure values ​​on both sides is within a preset range, it indicates that the clamping jaws 701 can be closed by applying pressure through the pipeline. If one side is larger than the other side, it indicates that the angle needs to be adjusted until the pressure difference on both sides is within a preset range before clamping. The deflection direction is to rotate toward the side with a smaller pressure value. The two piston heads 803 are respectively provided in the two piston chambers 802 and the two piston chambers 802 are divided into a first chamber 8021, a second chamber 8023, a third chamber 8022 and a fourth chamber 8024. The two piston rods 801 extend to the second connecting end.

[0039] The pipeline includes four pipes and is respectively connected to the first chamber 8021, the second chamber 8022, the third chamber 8023 and the fourth chamber 8024 for supplying gas to drive the piston rod 801 to extend and retract;

[0040] The clamping jaw group 70 includes two groups, each group includes two clamping jaws 701 that can be opened and closed and are hinged to the second connection end, the clamping jaw 701 has a clamping end and a driving end, and its hinge point is located between the clamping end and the driving end, and the driving end is hinged to the piston rod 801. When the piston rod 801 is extended or retracted, the two clamping jaws 701 are driven to rotate around their respective hinge points to open or close;

[0041] Before clamping, the air pressure in the first chamber 8021 and the second chamber 8023 is greater than that in the third chamber 8022 and the fourth chamber 8024 to push the piston toward the second connection end so that the piston rod 801 extends and drives the clamping jaw 701 to open. Specifically, It also includes an upper mounting plate and a lower mounting plate arranged on the mounting seat body 80, two hinged shafts arranged between the two mounting plates, two clamping jaws 701 rotatably arranged on the hinged shafts, a sliding shaft arranged on the piston rod 801, and two driving arms 702 rotatably arranged on the sliding shafts, the other ends of the two driving arms 702 are hinged to one end of the clamping jaw 701, the two ends of the sliding shaft pass through the upper mounting main plate and the lower mounting plate, and the upper and lower mounting plates are provided with strip-shaped sliding holes for sliding the sliding shafts, wherein the middle part of the clamping jaw 701 is rotatably connected to the hinged shaft, the left end of the clamping jaw 701 is rotatably connected to the sliding shaft, the right end of the clamping jaw 701 is provided with a detachable clamping block 703, and the clamping block 703 is provided with an arc-shaped clamping surface matching the side wall of the pole;

[0042] During clamping, if the two groups of jaws 701 are simultaneously sleeved on the pole, the piston rod 801 is compressed to drive the two piston heads 803 to move toward the first connection end, and at the same time, the third chamber 8022 and the fourth chamber 8024 are pressurized through the pipeline to ensure that the clamping of the jaws 701 is stable. When one group of jaws 701 is sleeved on the pole, one of the piston rods 801 is compressed, and the pressure in the first chamber 8021 and the second chamber 8023 increases and is greater than the air pressure in the third chamber 8022, so that the other piston rod 801 is in an extended state, and the other group of jaws 701 is in an open state. Then, the angle of the mounting seat 80 is adjusted to make the other group of jaws 701 sleeved on the pole. At this time, the other piston rod 801 is compressed to drive the jaws 701 to close and clamp the pole. Finally, the third chamber 8022 and the fourth chamber 8024 are pressurized through the pipeline to make both groups of jaws 701 in a clamped state.

[0043] like Figure 7-9As shown, it also includes a connecting rod mechanism 50, which includes a first connecting rod 500, a second connecting rod 501, a third connecting rod 502 and a fourth connecting rod 503. The first connecting rod 500 is connected to the robot arm 20, the second connecting rod 501 and the third connecting rod 502 are parallel and one end of both is rotatably connected to the first connecting rod 500, the fourth connecting rod 503 is parallel to the first connecting rod 500 and the other ends of the second connecting rod 501 and the third connecting rod 502 are rotatably connected to the fourth connecting rod 503, and a first driving mechanism 504 is provided on the first connecting rod 500, and the first driving mechanism 504 drives the second connecting rod 501 or the third connecting rod 502 to rotate, and the mounting seat 80 is arranged on the fourth connecting rod 503. When the connecting rod mechanism 50 is extended, the first connecting rod 500 and the fourth connecting rod 503 always remain parallel. At the same time, during adjustment, the first connecting rod 500 and the second connecting rod 501 are offset so that the mounting seat body 80 on the fourth connecting rod 503 can be offset to achieve the adjustment of the pole clamping position. It should be noted that in this embodiment, the first connecting rod 500 is combined with the flip seat 40, and a set of second connecting rods 501 and third connecting rods 502 are installed on the front side wall of the fourth connecting rod 503, and the mounting seat body 80 is set on the rear side wall of the fourth connecting rod 503. At the same time, in order to increase the structural strength, the fourth connecting rod 503 can be widened and a mounting groove 5031 is opened in the middle thereof, and another set of second connecting rods 501 and third connecting rods 502 is set between the mounting groove 5031 and the flip seat 40. The front and rear sets of second connecting rods 501 and third connecting rods 502 are arranged on the front and rear sides of the second connecting rod 503. 01 and the projections of the third link 502 in the front and rear directions overlap. When the link is set as a group, the first drive mechanism 504 and the second link 501 are respectively arranged on the front and rear sides of the first link 500. When the link is set in two groups, a mounting frame is required to be provided on the first link 500 or the flip seat 40 for installing the first drive mechanism 504. The second link 501 and the third link 502 are both fixed with hinge shafts extending into the first link 500, and the first drive mechanism drives one of the hinge shafts to rotate.

[0044] The first option: Fig. 9 As shown, the fourth connecting rod 503 is provided with a second driving mechanism 505 for driving the mounting seat body 80 to rotate. The second driving mechanism 505 is used to drive the mounting seat body 80 to rotate, thereby adjusting the posture of the clamping structure on the mounting seat body 80 to align with the pole.

[0045] The second option: Figure 7-8As shown, the fourth connecting rod 503 is provided with an installation cavity with a cover plate, and the installation cavity is provided with a parallel first rotating plate 509 and a second rotating plate 510 and a parallel first pull rod 507 and a second pull rod 508. The first pull rod 507 and the second pull rod 508 are both rotatably hinged between the first rotating plate 509 and the second rotating plate 510 so that the first rotating plate 509, the first pull rod 507, the second rotating plate 510 and the second pull rod 508 form a parallelogram structure with adjustable side spacing. The third connecting rod 502 is rotatably connected to the fourth connecting rod 503 through a first rotating shaft 511 extending into the installation cavity, and the first rotating shaft 511 is fixed to the middle of the first rotating plate 509. The middle of the second rotating plate 510 is provided with a second rotating shaft 506, and the second rotating shaft 506 extends out of the fourth connecting rod 503 and is connected to the mounting seat body 80. When the position of the structure is adjusted by the link mechanism 50, the mounting seat body 80 rotates accordingly. During the adjustment, the fourth link 503 and the first link 500 always remain parallel, and the angle of the mounting seat body 80 equivalent to the fourth link 503 is changed, so that the posture of the clamping structure is adjusted to adapt to the non-horizontally placed pole. The first link 500 and the flip seat 40 can be combined into the same structure, that is, the flip seat 40 is used as the first link 500.

[0046] The first scheme is used to adjust the deflection angle of the clamping, that is, when the piston rod 801 of the clamping jaw 701 on one side is compressed and the piston rod 801 on the other side is not compressed, it deflects to the side with a smaller pressure value until the difference in pressure values ​​on both sides is within a preset range and then closes and clamps. Direction adjustment can be directly rotated and adjusted by the second drive mechanism 505, and an angle sensor can be equipped for angle control; in addition, the deflection angle can also be adjusted by the structure in the second scheme. This adjustment method uses the connecting rod mechanism 50 for adjustment. When the angle of the clamping part changes, the distance between the clamping part and the pole will also change to a certain extent. Therefore, position compensation needs to be performed by the mechanical arm 20 during adjustment.

In this solution, the chamber isolated by the piston head 803 is pressurized and depressurized respectively through two pipelines, thereby driving the piston head 803 to move, and the movement of the piston head 803 drives the opening and closing of the clamping jaws 701.

[0050] Preferably, two main pipes are provided with high-pressure resistant air intake control valves and two main pipes are provided with branch pipes, and the branch pipes are provided with high-pressure resistant pressure relief control valves.
