The inner wall of the sliding tube A403 is slidably connected to a limit pin A405, which is inserted into the guide rail 402 and slides therein, and a magnetic block A used in conjunction with the electromagnet A404 is installed at the bottom of the limit pin A405. When the electromagnet A404 is started, it can generate a repulsive force on the magnetic block A, causing the limit pin A405 to slide upward.

[0024] like Figure 5 As shown, the shielding mechanism also includes a connecting rod A501, and the bottom end of the sliding tube A403 is symmetrically hinged with the connecting rod A501, and one end of the two connecting rods A501 is hinged with the same arc rod 502, and the bottom of the connecting frame A1 is fixedly connected with a guide frame 503, and the arc rod 502 is slidingly connected to the guide frame 503, and six evenly distributed sliding shafts 504 are horizontally slidably connected in the guide frame 503, and the six sliding shafts 504 are all used in conjunction with the arc rod 502, and the bottom ends of the six sliding shafts 504 are hinged with connecting rods B505, and the bottom of the connecting frame A1 is fixedly connected with six evenly distributed L-shaped frames 506, and the six L-shaped frames 506 are arranged in a one-to-one correspondence with the six sliding shafts 504, one end of the connecting rod B505 is inserted into the L-shaped frame 506 and slides therein, and a support rod is connected between the connecting rod B505 and the elastic telescopic curtain 207.

[0025] Initially, if Figure 2As shown, the telescopic end of the hydraulic cylinder B303 is in a retracted state, the telescopic end of the telescopic shaft in the drive assembly 205 is in a retracted state, the arc surface of the side baffle 203 fits with the arc surface of the clamp A201 or the clamp B202, and the overall equipment is suitable for grabbing sand and gravel materials. First, the hydraulic cylinder A302 is started, and the telescopic end of the hydraulic cylinder A302 is retracted, so that the two clamps A201 rotate upward with the connection of the connecting frame A1 as the center of the circle, and the four clamps B202 rotate upward with the connection of the corresponding connecting frame B301 as the center of the circle, and then the clamps are lifted by the lifting equipment. A201 and clamp B202 move to the top of the material, control the telescopic end of hydraulic cylinder A302 to extend, so that clamp A201 and clamp B202 rotate and reset, clamp A201 and clamp B202 grab the material, and then start electromagnet A404, electromagnet A404 produces repulsive force on the magnetic block A at the bottom of the adjacent limit pin A405, so that the magnetic block A drives the limit pin A405 to slide upward, and after the limit pin A405 slides, the top of the limit pin A405 is stuck in the corresponding guide rail 402, and then start hydraulic cylinder C401, hydraulic cylinder C The telescopic end of 401 extends, so that the two guide rails 402 move away from each other, and the inner wall of the guide rail 402 squeezes the outer wall of the limit pin A405, so that the limit pin A405 drives the sliding tube A403 to slide horizontally in the connecting frame A1. At this time, the two sliding tubes A403 squeeze the arc rod 502 through the connecting rod A501, so that the two arc rods 502 slide away from each other. After the arc rod 502 slides, it squeezes the three adjacent sliding shafts 504. The sliding shafts 504 slide horizontally in the guide frame 503 under force, and drive the corresponding connecting rod B505 to move. The end of B505 away from the sliding shaft 504 slides vertically downward along the inner wall of the corresponding L-shaped frame 506, and drives the corresponding elastic telescopic curtain 207 to extend downward through the support rod. Then the elastic telescopic curtain 207 contacts the top of the side baffle 203.

[0026] When it is necessary to grab a slender material such as a steel pipe, the hydraulic cylinder B303 is started, and the telescopic end of the hydraulic cylinder B303 extends to drive the piston plate 304 to descend. The piston plate 304 squeezes the air in the air storage tank 204, so that the air enters the inner cavity of the telescopic shaft in the drive component 205 through six hoses. The telescopic end of the telescopic shaft extends and drives the corresponding rack to rise upward.

It should be noted that at this time, the electromagnet A404 and the hydraulic cylinder C401 will not be activated, and the elastic telescopic curtain 207 will not extend downward, thereby preventing the slender materials such as steel pipes from contacting the elastic telescopic curtain 207 and causing damage to the elastic telescopic curtain 207.

[0027] Embodiment 2 As Figure 7 shown, it further includes a deformation mechanism. The deformation mechanism includes an arc track B601.

When the electromagnet B603 is activated, it can generate a repulsive force on the magnetic block B to make the limit pin B604 slide upward.

[0028] As Figure 3 、 Figure 8 and Fig. 9 shown, the balance mechanism further includes a special-shaped frame 701. The special-shaped frame 701 is installed on the top of the connecting frame A1. The hydraulic cylinder B303 is installed at the bottom of the special-shaped frame 701. A hinge seat 702 is hinged on the special-shaped frame 701 for connecting with a lifting device.

A C-shaped frame 704 is vertically slidably connected to the special-shaped frame 701. Two locking pins 705 are symmetrically and fixedly connected to both sides of the bottom of the C-shaped frame 704. Two groups of limit holes used in cooperation with the locking pins 705 are symmetrically provided on the rectangular frame 703, and the locking pins 705 are used to limit the position of the rectangular frame 703.

[0029] As Figure 8 and Fig.10 shown, the balance mechanism further includes a balance box 801. The balance box 801 is fixedly connected to the front side of the special-shaped frame 701. A groove is provided inside the balance box 801, and a balance ball 802 is arranged in the groove. The groove is used to limit the position of the balance ball 802. Trigger switches 803 used in cooperation with the balance ball 802 are symmetrically installed on the inner wall of the balance box 801.

[0030] As Figure 8 and Fig. 9 As shown, the balance mechanism further includes a hydraulic cylinder D901. The hydraulic cylinder D901 is symmetrically installed on the special-shaped frame 701. The special-shaped plates 902 are symmetrically and fixedly connected to the rectangular frame 703. The telescopic end of the hydraulic cylinder D901 is used in cooperation with the special-shaped plate 902. The special-shaped plate 902 is slidably connected to the special-shaped frame 701, and an elastic member A is provided between the special-shaped plate 902 and the special-shaped frame 701. The elastic member A is a compression spring. A Z-shaped rod 903 is fixedly connected to one side of the special-shaped plate 902, and the Z-shaped rod 903 is used in cooperation with the U-shaped frame 704.

[0031] As Fig.11 shown, it further includes a hydraulic cylinder E1001. The hydraulic cylinder E1001 is symmetrically installed on both sides inside the rectangular frame 703. The telescopic ends of the hydraulic cylinder E1001 are symmetrically hinged with connecting rods E1002. One end of the connecting rod E1002 is hinged to the jaw C208. When the telescopic ends of the hydraulic cylinder E1001 extend, the adjacent two jaws C208 can be combined.

[0032] As Fig.11 shown, it further includes a fixing frame 1101. A fixing frame 1101 is provided on one side of the jaw C208. A number of protrusions are provided at the bottom of the fixing frame 1101. An elastic member B is provided between the fixing frame 1101 and the jaw C208. The elastic member B is an elastic telescopic rod.

[0033] Initially, the special-shaped frame 701 is in a vertical state, and the locking pin 705 is inserted into the limiting hole of the rectangular frame 703, so that the rectangular frame 703 cannot move horizontally. When it is necessary to grab wood, the staff will pull out the pin, and the pin will be disengaged from the sockets of the connecting frame A1 and the connecting frame B301, and the hydraulic cylinder B303 will be started, thereby rotating the side baffle 203, so that a gap is generated between the clamping claw A201 and the clamping claw B202, and then the electromagnet B603 will be started. The electromagnet B603 will generate a repulsive force on the magnetic block B at the bottom of the adjacent limiting pin B604, so that the magnetic block B drives the limiting pin B604 to lift upward, and the top of the limiting pin B604 is stuck in the adjacent guide rail 402, and then the hydraulic cylinder C401 will be started to move the two guide rails 402 away from each other, and the guide rails 402 will be moved away from each other. The rail 402 squeezes the outer wall of the adjacent limit pin B604, and the limit pin B604 is forced to drive the sliding tube B602 to slide along the inner wall of the corresponding arc track B601, and the sliding tube B602 drives the corresponding connecting frame B301 to rotate with the connection of the connecting frame A1 as the center of the circle, and finally makes the connecting frame B301 parallel to the adjacent connecting frame A1, so that the clamping claw B202 is parallel to the adjacent clamping claw A201, and then the hydraulic cylinder A302 is started, so that the clamping claw A201 and the clamping claw B202 grab the wood, and when the wood is grabbed and leaves the ground, the hydraulic cylinder E1001 is started, and the telescopic end of the hydraulic cylinder E1001 extends, and drives the corresponding two clamping claws C208 through the connecting rod E1002 to rotate with the connection of the rectangular frame 703 as the center of the circle. Rotating downward, the clamping jaw C208 drives the corresponding fixing frame 1101 to rotate through the elastic member B. After the fixing frame 1101 rotates, it contacts and squeezes the wood on the upper side. The elastic member B contracts under the force until the two adjacent clamping jaws C208 abut against each other. The two adjacent clamping jaws C208 completely wrap the wood. The fixing frame 1101 is driven by the elastic member B to squeeze the wood, so that the wood wrapped by the two clamping jaws C208 can be kept stable, and the protrusion on the bottom surface of the fixing frame 1101 can further increase the friction between the wood and the fixing frame 1101, thereby effectively improving the clamping effect of the clamping jaw C208 on the wood. Since the wood is long, it is difficult to make the center of gravity of the wood coaxial with the connecting frame A1 when the clamping jaws A201 and the clamping jaws B202 clamp the wood, and the wood is grasped and lifted upward When the wood is lifted, the center of gravity of the wood tilts and is applied to the connecting frame A1 through the clamp A201 and the clamp B202. The connecting frame A1 is forced to drive the special-shaped frame 701 to rotate with the connection of the hinge seat 702 as the center of the circle. The special-shaped frame 701 drives the balancing box 801 and the rectangular frame 703 to rotate. The rectangular frame 703 is no longer perpendicular to the hinge seat 702. After the balancing box 801 rotates, the balancing ball 802 is affected by its own weight and leaves the groove of the balancing box 801, and rolls in the balancing box 801. Then the balancing ball 802 contacts and squeezes one of the trigger switches 803. The trigger switch 803 is forced to start one of the hydraulic cylinders D901. The telescopic end of the hydraulic cylinder D901 extends. Then the telescopic end of the hydraulic cylinder D901 contacts and squeezes one end of the Z-shaped rod 903.The Z-shaped rod 903 is forced to squeeze the wedge-shaped surface at the bottom of the rectangular frame 704, and the rectangular frame 704 is forced to drive the locking pin 705 to lift upward. After the locking pin 705 is lifted upward, it will be separated from the limiting hole of the rectangular frame 703. At the same time, one end of the Z-shaped rod 903 contacts and squeezes one side of the special-shaped plate 902. The special-shaped plate 902 is forced to drive the rectangular frame 703 to slide along the special-shaped frame 701, and the elastic member A is forced to shrink. The rectangular frame 703 drives the wood to move through the four clamping claws C208 thereon, thereby adjusting the center of gravity of the wood. As the center of gravity of the wood is adjusted, Point adjustment, the special-shaped frame 701 gradually rotates and resets with the connection of the hinge seat 702 as the center, and drives the balance box 801 and the rectangular frame 703 to rotate and reset, the balance ball 802 rolls and resets inside the balance box 801, and the telescopic end of the hydraulic cylinder D901 no longer extends. Through the above steps, the center of gravity of the wood can be prevented from tilting, making it easier for the entire equipment to clamp the wood and move, and then the hydraulic cylinder A302 is started again, so that the clamping claws A201 and B202 can grab the wood again, increasing the stability of grabbing the wood.

[0034] After the wood is clamped and transported, first control the telescopic end of hydraulic cylinder A302 to retract, so that jaws A201 and jaws B202 open and the wood is put down, and then control the telescopic end of hydraulic cylinder D901 to retract and reset. The telescopic end of hydraulic cylinder D901 is no longer in contact with the corresponding Z-shaped rod 903. Z-shaped rod 903 can move after being freed from the restriction. The rectangular frame 704 slides down and resets under the influence of its own weight, and squeezes the wedge-shaped surface at one end of the Z-shaped rod 903. The Z-shaped rod 903 is forced to slide and reset. The elastic member A is released and drives the rectangular frame 703 to slide and reset through the special-shaped plate 902. Then control the telescopic end of hydraulic cylinder A302 to extend, so that jaws A201 and jaws B202 rotate and reset.
