[0028] The taking mechanism 7 comprises a connecting assembly, a support 707 and a sliding frame 708 on the connecting assembly, the right side of the support 707 is in sliding connection with the left side of the sliding frame 708, the support 707 and the sliding frame 708 can move up and down and left and right relative to the fixed plate 1, the connecting assembly comprises a hydraulic telescopic rod 701, the left end of the hydraulic telescopic rod 701 is hinged to the upper surface of the fixed plate 1, the right end of the hydraulic telescopic rod 701 is hinged to a connecting plate 702, the right upper part and the right lower part of the connecting plate 702 are both hinged to a hinged sleeve 703, the right end of the hinged sleeve 703 is hinged to a rotating sleeve 704, the inner wall of the rotating sleeve 704 is rotatably connected with a moving rod 705 through a bearing, the front end and the rear end of the moving rod 705 both extend into the inside of the limiting hole 3, the upper side of the rotating sleeve 704 is hinged to a mounting plate 706, the right side of the mounting plate 706 is fixedly connected with the left side of the support 707, the left side of the support 707 is fixedly connected with a support pile 709, the upper end inner wall of the support pile 709 is rotatably connected with a bidirectional threaded rod 710 through a bearing, the upper side of the mounting plate 706 is fixedly connected with a motor 711, the output end of the motor 711 is in transmission connection with the outer wall of the bidirectional threaded rod 710 through a bevel gear set, the lower side of the mounting plate 706 is provided with two rotating sleeves 704, the upper ends of the two rotating sleeves 704 are both hinged to the lower surface of the mounting plate 706, and the mounting plate 706 is horizontally arranged, the sliding frame 708 is vertically arranged, and the upper surfaces of the two rotating sleeves 704 can support the mounting plate 706 to be in a horizontal state during deflection;

[0029] In use, the left and right counterbalance is achieved by placing counterweights in the counterweight grooves 4, the device is pushed to the front side of the window, and then the hydraulic telescopic rod 701 is started to drive the connecting plate 702 to move forward and upward, so that the connecting plate 702 drives the hinged sleeve 703 and the rotating sleeve 704 to deflect, the rotating sleeve 704 drives the mounting plate 706, the support 707 and the sliding frame 708 to move to the front lower side, then when the two sliding frames 708 move to the two sides of the window, the motor 711 is started to drive the bidirectional threaded rod 710 to rotate under the support of the support pile 709 through the transmission of the bevel gear, so that the bidirectional threaded rod 710 drives the two sliding frames 708 to move close to the middle, and when the two sides of the window are clamped, the window can be lifted by starting the hydraulic telescopic rod 701 to shrink, and then the window can be transported to the designated location, so that the step of manually moving the window onto the cart and then fixing and transporting is replaced;

[0030] Since the rotating sleeve 704 needs to deflect forward and downward when the sliding frame 708 moves to the two sides of the window, the rotating sleeve 704 deflects to the left upper part when the window is lifted, so that the window is lifted away from other windows on the right side or the support on which the window is placed during the process of lifting the window off the ground, so that manual support of the window or lifting of the window off the support is not needed, and the carrying efficiency is improved;

[0031] The fault-tolerant mechanism 6 comprises a rubber sliding block 601, an outer wall of the rubber sliding block 601 is in sliding connection with an outer wall of the sliding frame 708, an upper end of the rubber sliding block 601 is fixedly connected with a fourth spring 615, a lower end of the fourth spring 615 is fixedly connected with an upper side of the sliding frame 708, a side wall of the rubber sliding block 601 is fixedly connected with a plug rod 602, a lower side of the plug rod 602 is provided with a plug barrel 603, an outer wall of the plug barrel 603 is fixedly connected with an outer wall of the sliding frame 708, a lower end of the plug rod 602 is inserted into the inside of the plug barrel 603, a side wall lower part of the plug barrel 603 is fixedly connected with a connecting pipe 604, a side wall of the fixed plate 1 is fixedly connected with a sliding barrel 605, one end of the connecting pipe 604 is fixedly connected with an outer wall of the sliding barrel 605, the inside of the sliding barrel 605 is in communication with the inside of the plug barrel 603 through the connecting pipe 604, a lower side of the sliding barrel 605 is fixedly connected with a reinforcing plate 606, an outer wall of the reinforcing plate 606 is fixedly connected with a side wall of the fixed plate 1, an inner wall of the sliding barrel 605 is in sliding connection with a blocking rod 607, one side of the blocking rod 607 is fixedly connected with a first spring 608, the other end of the first spring 608 is fixedly connected with the inner wall of the sliding barrel 605, and the fault-tolerant mechanism 6 further comprises a connecting sleeve 609, an outer wall of the connecting sleeve 609 is fixedly connected with an outer wall of the moving rod 705, a lower side of the connecting sleeve 609 is fixedly connected with a second spring 610, the lower side of the second spring 610 is fixedly connected with an outer wall of the fixed plate 1, the height of the sliding barrel 605 is located on the upper side of the upper end of the hinged sleeve 703, and one end of the moving rod 705 extends to the front side of the upper end of the hinged sleeve 703, and the upper side of the hinged sleeve 703 is located in the movement path of the blocking rod 607;

[0032] When the device is not loaded with goods, the connecting plate 702 can smoothly push the upper end of the hinged sleeve 703 to produce deflection, and then make the sliding frame 708 move to the right side of the front part, so that it can be more easily aligned with the two sides of the window. When the load lifts the window, the outer wall of the rubber sliding block 601 is in close contact with the outer wall of the window, which makes the window drive the rubber sliding block 601 to slide downward relative to the sliding frame 708, and then makes the fourth spring 615 contract, so that the connecting plate 702 is inserted into the inside of the hinged sleeve 703, and then the gas in the inside of the hinged sleeve 703 is discharged into the inside of the sliding cylinder 605 through the connecting pipe 604. Immediately, the blocking rod 607 is pushed out of the inside of the sliding cylinder 605 due to the gas in the inside of the sliding cylinder 605, and at the same time, the first spring 608 is deformed to store energy. After the blocking rod 607 extends out of the inside of the sliding cylinder 605, one end of the blocking rod 607 moves to the upper side of the hinged sleeve 703. When the window is moved to the specified position, the upper end of the hinged sleeve 703 is blocked by the blocking rod 607 due to the fact that the connecting plate 702 is pushed by the hydraulic telescopic rod 701 to make the upper end of the hinged sleeve 703 produce deflection to the right side of the front part. Therefore, the connecting plate 702 pushes the hinged sleeve 703 to move forward, and at the same time, the second spring 610 is compressed and deformed to make the hinged sleeve 703 push the rotating sleeve 704 and the moving rod 705 to move downward. Since the lower end of the limiting hole 3 is deflected to the left side, the moving rod 705 moves to the left during the downward movement, and then the movement distance to the left of the moving rod 705 offsets the movement distance of the upper end of the rotating sleeve 704 to the right, so that the sliding frame 708 vertically falls, and then the window can be accurately placed in front of the other windows of the support, so as to avoid affecting the rear side of the window during the placement process, and make the placement process more smooth. After the window is placed, the motor 711 is started to make the two sliding frames 708 move to the two sides to make the window be placed down. Then, the blocking rod 607 is pulled back to the original position due to the elasticity of the first spring 608, the rubber sliding block 601 is pushed back to the original position by the fourth spring 615, and the connecting sleeve 609 and the moving rod 705 are pushed back to the original position by the second spring 610.

[0033] The fault-tolerant mechanism 6 further comprises an air hole 611, which is a through hole opened in the upper side of the sliding cylinder 605. The upper surface of the sliding cylinder 605 is slidably connected with a sealing block 613. One side of the sealing block 613 is fixedly connected with a third spring 612. One end of the third spring 612 is fixedly connected with the side wall of the fixed plate 1. The air hole 611 is located below the sealing block 613. The side wall of the connecting plate 702 is fixedly connected with a push rod 614. One end of the push rod 614 extends to the left side of the sealing block 613. The upper surface of the sealing block 613 is inclinedly arranged. The upper part of the left side of the sealing block 613 is lower than the upper part of the right side of the sealing block 613.

[0034] After the upper end of the hinged sleeve 703 is blocked by one end of the blocking rod 607, the connecting plate 702 will push the hinged sleeve 703 to produce a rightward translation, so that the connecting plate 702 drives the push rod 614 to move rightward, at this time, the window is in the process of slowly lowering, but the push rod 614 pushes the sealing block 613 to produce deflection, so that the air hole 611 is exposed to the outside, at this time, the gas in the sliding cylinder 605 is slowly discharged through the air hole 611, so that the plug rod 602 is slowly inserted into the inside of the plug cylinder 603, at this time, the movement of the hydraulic telescopic rod 701 can be stopped, so that the plug rod 602 slowly makes the rubber sliding block 601 fall slowly due to the slow discharge of the gas in the plug cylinder 603, and then the window is slowly placed on the ground, avoiding that the downward force of the device when placing the window causes the lower side of the window to be damaged, and because the rubber sliding block 601 and the sliding frame 708 can slide relative to each other, when the hydraulic telescopic rod 701 quickly places the window, if the window lower side protection is in place, the sliding frame 708 will still have room to move after the window falls to the ground, so that the operation error space is increased, the probability of damage to the window is reduced, and then the carrying process is faster.
