The cylinder push rod of the first cylinder pushes the first sliding rail and the first sliding block to generate relative displacement, so that the clamping jaw is driven by the first sliding rail to move along the extending direction of the first sliding rail.

The vertical motion mechanism of clamping jaw includes: a second slide rail 7, a second cylinder 10 and a second slider 71.

The second sliding block is arranged at the other end of the sliding block mounting seat, which is far away from the first sliding block, and the second sliding rail is fixed on the second fixing plate, and the extending direction of the second sliding rail after fixing is consistent with the extending direction of the second fixing plate; the second sliding block can slide on the second sliding rail along the extending direction of the second sliding rail; the sliding direction of the second sliding block is perpendicular to the sliding direction of the first sliding block.

The cylinder push rod of the second cylinder pushes the second sliding rail and the second sliding block to generate relative displacement, so that the clamping jaw is driven by the second sliding rail to move along the extending direction of the second sliding rail.

The bolt dismounting mechanism comprises: two guide posts 18, two linear bearings 16, a mechanism fixing seat 14, a guide post connecting plate 15, a sleeve 11, a pneumatic wrench 12, a pneumatic wrench flange plate 13, an elastic element 17, a double-shaft air cylinder 25 and an air cylinder mounting plate 26.

The two guide posts are respectively fixed on two sides of the second fixing plate, the fixed guide posts are positioned at the bottom of the second fixing plate, and the two linear bearings are respectively sleeved on the fixed guide posts.

The mechanism fixing seat is in threaded connection with each of the two linear bearings, so that the mechanism fixing seat and the linear bearings can perform linear motion on the guide along the extending direction of the guide column.

The sleeve is installed on the rotor of the pneumatic wrench, the pneumatic wrench is fixed on the pneumatic wrench flange plate, and the pneumatic wrench flange plate is fixed on the mechanism fixing seat.

The elastic element is sleeved on each guide post, one end of the elastic element is connected with the second fixing plate, and the other end of the elastic element is connected with the mechanism fixing seat.

The two ends of the guide post connecting plate are respectively fixedly connected with different guide posts, so that the guide posts are fixed.

The double-shaft air cylinder is fixedly arranged on the bottom surface of the mechanism fixing seat through the air cylinder mounting seat.

Specifically, the sleeve 11 may be an outer hexagonal sleeve. The elastic element may be a spring.

The working process of the bolt dismounting mechanism is as follows: the initial state of the elastic element is a compressed state after being connected to the guide post; under the action of elasticity generated under the compression state of the elastic element, the bolt dismounting mechanism moves in a direction away from the second fixing plate, so that a mechanism fixing seat of the bolt dismounting mechanism is contacted with the guide post connecting plate in an initial state.

When the bolts mounted on the blades are required to be disassembled, the mechanical arm drives the clamp module to move towards the bolts on the blades, so that the sleeve of the bolt disassembling mechanism in the clamp module is in contact with the bolts to be disassembled; when the sleeve is contacted with the bolt to be disassembled and is not sleeved into the bolt, the bolt to be disassembled can apply resistance to the sleeve, which is opposite to the action direction of the elastic force generated by the elastic element, and when the resistance is larger than the elastic force generated by the elastic element, the bolt disassembling mechanism moves towards the direction close to the elastic element under the action of the resistance and compresses the elastic element in the moving process until the bolt disassembling mechanism moves for a preset distance; when the sleeve is sleeved into the bolt to be disassembled, the resistance disappears, so that the elastic element is restored to be deformed to an initial state, the rotor of the pneumatic wrench rotates to bring the sleeve into rotation, the bolt is disassembled, the bolt is unscrewed from the blade, and the bolt disassembling mechanism compresses the elastic element in the process of unscrewing the bolt from the blade; when the bolts are all screwed out of the blades, the double-shaft air cylinder stretches out of the push rod to prop against the elastic element, the double-shaft air cylinder is ejected, the second air cylinder is retracted, the clamping jaw is aligned with the bolts, and the clamping jaw air cylinder controls the clamping jaw to tighten the bolts; when the clamping jaw clamps the bolt, the mechanical arm controls the clamp module to move towards the bolt placing area, and when the clamp module reaches the bolt placing area, the clamping jaw cylinder controls the clamping jaw to loosen, and the detached bolt is placed in the bolt placing area.

In one embodiment, the preset distance may be set to 35mm.

Here, the biaxial cylinder is ejected and the second cylinder is retracted so that the V-port of the jaw aligns with the bolt.

The clamp module further comprises: the connecting block 31, the hydraulic limiter 4, the hydraulic buffer 9, the first L-shaped flange plate 29 and the second L-shaped flange plate 30.

The hydraulic limiter is fixed on the sliding block mounting seat through the first L-shaped flange plate, and the connecting block is mounted at a position, close to the hydraulic limiter, of the sliding block mounting seat.

When the first fixing plate moves along with the vertical movement mechanism of the clamping jaw in the vertical direction, the connecting block is in contact with the hydraulic limiter, so that the functions of buffering and adjusting the stroke are achieved.

The hydraulic buffer is fixed at a position, close to the second cylinder, on the second fixing plate through the second L-shaped flange plate. Adjusting the nut and mounting position of the hydraulic damper controls the stroke of retraction of the second cylinder 10 and thus the position at which the clamping jaw 1 stops.

Further, the clamp module further includes: a baffle (not shown), an image acquisition unit 20, a sensor holder 24, a photoelectric sensor (not shown), a metal sensor (not shown), and a third L-shaped flange plate 19.

The baffle is arranged on one side of the mechanism fixing seat, which is close to the elastic element, the sensor support is arranged on the second fixing plate, and the photoelectric sensor and the metal sensor are arranged on the sensor support.

In the process of screwing out the bolt from the blade, when the photoelectric sensor and the metal sensor are in contact with the baffle, the bolt disassembling mechanism determines that the bolt is completely screwed out of the blade.

The image acquisition unit 20 may employ a camera.

In addition to the above, the bolt removing apparatus proposed in the present embodiment has: the bolt is not loosened and protects the mechanism: when the clamping jaw is clamped and positioned by the bolt (at the moment, the bolt is loosened and the spring is compressed, the bolt is detected by the photoelectric sensor or the metal sensor after reaching the position), the double-stroke cylinder ejects one stroke, if the bolt is occasionally not loosened, one or two teeth are not loosened (the threads at the root of the wind power blade are not completely separated), the system is mistakenly considered to be completely loosened, when the clamping jaw clamps the bolt to be pulled out, the clamping jaw of the clamp module is blocked by the bolt head to be unable to move when the clamping jaw moves backwards due to the fact that the bolt is not moved, the second stroke of the double-stroke cylinder is separated from the initial position and is pulled up passively, at the moment, the sensor detects that the piston is separated from the preset position, the controller of the bolt dismounting device sends information, and the pneumatic robot stops running suddenly immediately after the controller receives the information.

Specifically, the structure of the device base a in the bolt disassembling device shown in fig. 4 is schematically shown, and the device base includes: a base body 39, universal wheels 40 and a support mechanism E.

The supporting mechanism further comprises: a bushing (not shown); the bushing is arranged in the hollow fixing seat and sleeved on the guide shaft penetrating through the hollow fixing seat.
