[0001] The present invention relates to the technical field of production equipment, and particularly to a safe handling device applicable to windows of different sizes. Background Art

[0002] In the construction, door and window installation, and glass manufacturing industries, the handling and installation of windows are important and challenging processes. Since windows are usually composed of glass and metal frames, they are heavy and fragile as a whole. Manual handling is not only laborious but also poses a high risk of breakage. During the installation process of high-rise buildings, handling windows also involves safety issues related to working at heights. Therefore, improving the handling efficiency and safety of windows has become a key concern in the industry;

[0003] Currently, the common window handling methods on the market mainly include manual handling, hoisting equipment handling, and mechanical clamping handling. Among them, the manual handling method relies on the strength of workers, with low efficiency and easy to cause window damage or personnel injury; hoisting equipment handling is suitable for large windows, but the equipment is bulky, the operation is complex, and it is difficult to operate in narrow spaces; mechanical clamping handling clamps the window through a mechanical structure, but existing devices are mostly designed for windows of fixed sizes and are difficult to adapt to windows of different sizes and structures, with poor versatility.

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figure 1-6 , the present invention provides a technical solution: a safe handling device applicable to windows of different sizes, including a fixed plate 1, a roller 2 is fixedly connected to the lower side of the fixed plate 1, a limit hole 3 is opened on the side wall of the fixed plate 1, a counterweight groove 4 is fixedly connected to the upper side of the fixed plate 1, a push handle 5 is fixedly connected to the left side of the fixed plate 1, and a goods picking mechanism 7 is arranged on the right side of the fixed plate 1. A fault tolerance mechanism 6 is arranged on the side wall of the roller 2. The counterweight groove 4 is a frame structure located in the upper left part of the fixed plate 1. The limit hole 3 is an opening penetrating the front and rear sides of the fixed plate 1, and the lower part of the limit hole 3 is offset to the left;

[0028] The picking mechanism 7 includes a connecting component and a bracket 707 and a slide 708 on the connecting component. The right side of the bracket 707 is slidably connected to the left side of the slide 708. The bracket 707 and the slide 708 can move up and down and left and right relative to the fixed plate 1. The connecting component includes 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 upper right part and the lower right part of the connecting plate 702 are both hinged to an articulated sleeve 703. The right end of the articulated sleeve 703 is hinged to a rotating sleeve 704. The inner wall of the rotating sleeve 704 is rotatably connected to a moving rod 705 through a bearing. The front end and the rear end of the moving rod 705 extend to the inside of the limiting hole 3. The rotating sleeve A mounting plate 706 is hinged on the upper side of 704, the right side of the mounting plate 706 is fixedly connected to the left side of the bracket 707, the left side of the bracket 707 is fixedly connected to a support pile 709, the inner wall of the upper end of the support pile 709 is rotatably connected to a bidirectional threaded rod 710 through a bearing, a motor 711 is fixedly connected to the upper side of the mounting plate 706, the output end of the motor 711 is transmission-connected to the outer wall of the bidirectional threaded rod 710 through a bevel gear set, two rotating sleeves 704 are arranged on the lower side of the mounting plate 706, 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 arranged horizontally, and the slide 708 is arranged vertically, and the two rotating sleeves 704 can support the upper surface of the mounting plate 706 to be in a horizontal state during the deflection process;

[0029] When in use, by placing a counterweight inside the counterweight slot 4 to balance the left and right counterweights, the device is pushed to the front side of the window and then the hydraulic telescopic rod 701 is started, so that the hydraulic telescopic rod 701 pushes the connecting plate 702 to move to the front and upper side, and then the connecting plate 702 drives the hinge sleeve 703 and the rotating sleeve 704 to deflect, so that the rotating sleeve 704 deflects and drives the mounting plate 706, the bracket 707, and the slide 708 to move to the front and lower side, and then when the two slides 708 move to both sides of the window, the motor 711 is started, so that the motor 711 drives the two-way threaded rod 710 to rotate under the support of the support pile 709 through the transmission of the bevel gear, and then the two-way threaded rod 710 drives the two slides 708 to move closer to the middle, and when the two sides of the window are clamped, the hydraulic telescopic rod 701 is started to retract to lift the window, and then the window can be transported to the designated location, which replaces the steps of manually moving the window onto the cart and then fixing it for transportation;

[0030] Since the rotating sleeve 704 needs to be deflected to the front and lower side when the slide 708 is moved to the two sides of the window, the rotating sleeve 704 is deflected to the upper left side when the window is lifted, so that the window is lifted off the ground away from other windows on the right side or the bracket on which the window is placed, and there is no need to manually support the window or lift the window off the bracket, thereby improving the handling efficiency;

[0031] The fault-tolerant mechanism 6 includes a rubber slider 601. The outer wall of the rubber slider 601 is slidably connected to the outer wall of the carriage 708. The upper end of the rubber slider 601 is fixedly connected to a fourth spring 615, and the lower end of the fourth spring 615 is fixedly connected to the upper side of the carriage 708. A plug rod 602 is fixedly connected to the side wall of the rubber slider 601. An insertion cylinder 603 is arranged below the plug rod 602. The outer wall of the insertion cylinder 603 is fixedly connected to the outer wall of the carriage 708. The lower end of the plug rod 602 is inserted into the interior of the insertion cylinder 603. A connecting pipe 604 is fixedly connected to the lower part of the side wall of the insertion cylinder 603. A sliding cylinder 605 is fixedly connected to the side wall of the fixed plate 1. One end of the connecting pipe 604 is fixedly connected to the outer wall of the sliding cylinder 605. The interior of the sliding cylinder 605 is communicated with the interior of the insertion cylinder 603 through the connecting pipe 604. A reinforcing plate 606 is fixedly connected to the lower side of the sliding cylinder 605. The outer wall of the reinforcing plate 606 is fixedly connected to the side wall of the fixed plate 1. A stop rod 607 is slidably connected to the inner wall of the sliding cylinder 605. A first spring 608 is fixedly connected to one side of the stop rod 607, and the other end of the first spring 608 is fixedly connected to the inner wall of the sliding cylinder 605. Moreover, the fault-tolerant mechanism 6 further includes a connecting sleeve 609. The outer wall of the connecting sleeve 609 is fixedly connected to the outer wall of the moving rod 705. A second spring 610 is fixedly connected to the lower side of the connecting sleeve 609, and the lower side of the second spring 610 is fixedly connected to the outer wall of the fixed plate 1. The height of the sliding cylinder 605 is located above the upper end of the hinge sleeve 703, and one end of the moving rod 705 extends to the front side of the upper end of the hinge sleeve 703. The upper side of the hinge sleeve 703 is within the movement path of the stop rod 607;

[0032] When picking up goods without load in this device, the connecting plate 702 can smoothly push the upper end of the hinge sleeve 703 to deflect, thereby causing the carriage 708 to move forward to the right side, making it easier to align with both sides of the window. When the load lifts the window, since the outer wall of the rubber slider 601 is in close contact with the outer wall of the window, the window will drive the rubber slider 601 to slide downward relative to the carriage 708, thereby causing the fourth spring 615 to contract, enabling the connecting plate 702 to insert into the inside of the hinge sleeve 703. Then, the gas inside the hinge sleeve 703 is discharged into the inside of the sliding cylinder 605 through the connecting pipe 604. Immediately, due to the push of the gas inside the sliding cylinder 605, the stop rod 607 is withdrawn from the inside of the sliding cylinder 605, and at the same time, the first spring 608 is deformed and stores energy. After the stop rod 607 extends out of the inside of the sliding cylinder 605, one end of it will move to the upper side of the hinge sleeve 703. When the window is moved to the designated position and placed, since the hydraulic telescopic rod 701 pushes the connecting plate 702 to cause the upper end of the hinge sleeve 703 to tend to deflect forward to the right side, and the upper end of the hinge sleeve 703 is blocked by the stop rod 607, the connecting plate 702 will push the hinge sleeve 703 to move forward. At the same time, the second spring 610 is compressed and deformed, causing the hinge sleeve 703 to push the rotating sleeve 704 and the moving rod 705 to move downward. Since the lower end of the limiting hole 3 deflects to the left, the moving rod 705 will move to the left during the downward movement, thereby offsetting the movement distance of the upper end of the rotating sleeve 704 deflecting to the right with its leftward movement distance, making the carriage 708 fall vertically. Thus, the window can be accurately placed in front of other windows on the bracket, avoiding affecting the rear side when placing the window and making the placement process smoother. After the window is placed, starting the motor 711 can cause the two carriages 708 to move to both sides to lower the window. Subsequently, the first spring 608 pulls the stop rod 607 back to its original position due to its elasticity, the fourth spring 615 pushes the rubber slider 601 back to its original position, and the second spring 610 pushes the connecting sleeve 609 and the moving rod 705 back to their original positions;

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

[0034] After the upper end of the hinge sleeve 703 is blocked by one end of the stop lever 607, when the connecting plate 702 pushes the hinge sleeve 703, it will cause a rightward translation, making the connecting plate 702 drive the push rod 614 to move rightward. At this time, the window is in the process of being slowly lowered. However, further, the push rod 614 pushes the sealing block 613 to cause it to deflect, exposing the air hole 611 to the outside. At this time, the gas inside the sliding cylinder 605 slowly discharges through the air hole 611, allowing the insertion rod 602 to slowly insert into the inside of the insertion cylinder 603. At this time, the movement of the hydraulic telescopic rod 701 can be stopped, and the insertion rod 602 slowly causes the rubber slider 601 to slowly fall due to the slow discharge of the gas inside the insertion cylinder 603. Furthermore, the window is slowly placed on the ground, avoiding damage to the lower side of the window caused by the downward force when the device places the window. And because the rubber slider 601 and the sliding frame 708 can slide relative to each other, when the window is quickly placed by the hydraulic telescopic rod 701, if the lower side of the window is well protected, there will still be room for the sliding frame 708 to move after the window lands, increasing the operation error space and reducing the probability of window damage, thus making the handling process faster.
