Description

Technical Field

[0001] This invention relates to the field of building equipment technology, specifically to a curtain wall unit flipping and transfer device. Background Technology

[0002] Unitized curtain walls are the mainstream building envelope structure for modern high-rise buildings. Each unit integrates glass, decorative panels, and a metal frame. The components are precision-engineered, and the appearance is demanding, making them highly susceptible to bumps, scratches, and deformation during the flipping process. Therefore, extremely high requirements are placed on the stability and positioning accuracy of the flipping operation. During the prefabrication and on-site construction of curtain wall units, specialized flipping equipment is needed to flip the horizontal units to a vertical position to meet the requirements of subsequent stacking, hoisting, and installation procedures. The stability of the flipping operation directly determines the finished product qualification rate and construction quality of the curtain wall units.

[0003] Existing curtain wall unit flipping and transfer equipment lacks a precise detection and segmented speed adjustment mechanism based on the flipping stroke position. There is no buffering and easing process during the equipment's flipping start and stop phases. Rigid start and stop will generate significant mechanical impact, which can easily lead to irreversible damage to components such as broken curtain wall glass, scratched panels, and deformed frames, greatly increasing product scrapping costs and construction rework costs. Summary of the Invention

[0004] The purpose of this invention is to provide a curtain wall unit flipping and transfer device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a curtain wall unit flipping and transfer device, comprising... The frame is an integral load-bearing base, and the upper left and right sides of the frame are symmetrically provided with first U-shaped seats; The first plate is used to support the curtain wall unit body. Two symmetrically arranged second plates are fixedly installed on one side of the bottom of the first plate. The two second plates are assembled into the two first U-shaped seats in a one-to-one correspondence. A first column is inserted between the second plate and the corresponding first U-shaped seat. The first column is fixedly connected to the second plate. The two ends of the second plate are rotatably connected to the first U-shaped seat through the first column, so that the first plate can be rotated relative to the frame. The end of the first column extends out of the outer end face of the first U-shaped seat. The hydraulic cylinder is a tilting drive component. The bottom end of the hydraulic cylinder is hinged to the frame, and the telescopic top end of the hydraulic cylinder is hinged to the first plate. The first plate is driven to complete the tilting action by the telescopic movement of the hydraulic cylinder. A speed control component, installed at the extended end of the first column, is used to control the rotation speed of the first plate. The speed control component includes a fifth plate, a first reflector, a second reflector, and a laser sensor. The fifth plate, first reflector, and second reflector are coaxially arranged sequentially in a direction away from the first column. The fifth plate is fixedly connected to the first column and rotates synchronously with the first column and the first plate. The laser sensor is fixedly installed on the fifth plate, and the line connecting the axis of the laser sensor and the axis of the fifth plate is parallel to the surface of the first plate. The first and second reflectors are both fixed relative to a first U-shaped seat. A first through hole is provided on the first reflector. The first and second through holes are both arc structures, with a central angle of 10° corresponding to a single arc segment, and the maximum included angle between the two through holes is 90°. The laser sensor and the PLC control system of the equipment are electrically coordinated to realize the speed control of the hydraulic cylinder. When the laser emitted by the laser sensor covers the area of ​​the first reflector, the PLC control system controls the hydraulic cylinder to extend and retract at high speed, causing the first plate to flip quickly. When the laser emitted by the laser sensor passes through the first or second through hole and irradiates the area of ​​the second reflector, the PLC control system controls the hydraulic cylinder to run at low speed, so that the first plate has a 10° slow movement range at the start and end positions of the flip.

[0006] As a further preferred embodiment of this technical solution, a third plate is also included. The third plate is disposed above the frame and is vertically arranged relative to the frame. It forms a positioning interlayer with the vertically arranged first plate to accommodate the curtain wall unit body.

[0007] As a further preferred embodiment of this technical solution, an adjustment unit is provided between the third plate and the frame. The adjustment unit includes a slider, a fourth plate, and a locking bolt. The fourth plate is fixedly mounted on the frame and located on the side of the third plate away from the first plate. A through groove is provided on the fourth plate, and the slider is slidably disposed in the through groove, with one end of it fixedly connected to the third plate. A threaded hole is provided on the side wall of the fourth plate, extending into the through groove. The locking bolt is disposed in the threaded hole, and the locking bolt is threadedly adapted to the threaded hole.

[0008] As a further preferred embodiment of this technical solution, a side plate is integrally formed on the lower side of the bearing surface of the first plate, and the side plate is used to support the bottom of the curtain wall unit body in a vertical state.

[0009] As a further preferred embodiment of this technical solution, a gap is left between the third plate and the frame component, which provides space for the rotation of the side plate.

[0010] As a further preferred embodiment of this technical solution, the top of the hydraulic cylinder is fixedly provided with a first connecting part, which is a cylindrical structure, and its two ends are rotatably connected to a second U-shaped seat through a rotating shaft.

The bottom of the hydraulic cylinder is fixedly provided with a second connecting part, which is a plate-shaped structure with a rotating hole. A second column is rotatably provided in the rotating hole, and the second column is fixedly connected to the frame.

[0011] As a further preferred embodiment of this technical solution, the fifth plate is provided with a mounting hole, the head of the laser sensor is disposed in the mounting hole, and the two are fixed together by threaded engagement. A connecting post is integrally formed at the end of the fifth plate, and a connecting plate is integrally formed at the end of the connecting post. The connecting plate is fixedly disposed at the end of the first post, thereby achieving relative fixation between the fifth plate and the first post.

[0012] As a further preferred embodiment of this technical solution, the speed control component further includes a sleeve, which is sleeved on the outside of the fifth plate. The two are coaxially arranged and have a clearance fit. One end of the sleeve is fixedly connected to the first U-shaped seat through a fixing plate.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] This invention provides a technical solution: such as Figure 1 As shown, in this embodiment, a curtain wall unit flipping and transferring device mainly consists of a frame 1, a first plate 2, a third plate 3, a hydraulic cylinder 4, and a speed control component 5. The entire device is used for the smooth flipping, precise positioning, and transfer of building curtain wall units. Figure 4 As shown, the frame 1 is the overall load-bearing base of the equipment, formed by welding of structural steel. First U-shaped seats 11 are symmetrically fixed on the left and right sides of the upper end of the frame 1. The two first U-shaped seats 11 are coaxially and symmetrically arranged, providing stable support points for the rotation and flipping of the first plate 2. The first plate 2 is the main load-bearing component of the curtain wall unit. Two symmetrically arranged second plates 22 are integrally fixed to one side of the bottom of the first plate 2. The two second plates 22 are respectively embedded in the internal grooves of the two first U-shaped seats 11. The second plates 22 and the first U-shaped seats 11... The first column 23 is connected through the frame 1 and fixedly connected to the second plate 22. The first column 23 is rotatably connected to the first U-shaped seat 11, thereby realizing the flipping and rotating action of the first plate 2 relative to the frame 1. The two ends of the first column 23 extend outward and protrude from the outer end face of the first U-shaped seat 11, providing an installation point for the speed control component 5. The lower side of the bearing surface of the first plate 2 is integrally formed with a side plate 21. When the first plate 2 is flipped to a vertical state, the side plate 21 can support and limit the bottom of the curtain wall unit body.

[0018] like Figure 3As shown, the hydraulic cylinder 4 is the core driving component for the equipment's tilting mechanism. It adopts a hydraulic telescopic drive mode. A cylindrical first connecting part 41 is fixedly installed at the top of the hydraulic cylinder 4. The two ends of the first connecting part 41 are rotatably connected to the second U-shaped seat 43 through a rotating shaft. The second U-shaped seat 43 is fixed to the bottom of the first plate 2, realizing the hinged engagement between the top of the hydraulic cylinder 4 and the first plate 2. A plate-shaped second connecting part 42 is fixedly installed at the bottom of the hydraulic cylinder 4. The second connecting part 42 has a rotating hole, and a second column 44 is assembled inside the rotating hole. The second column 44 is fixed on the frame 1, realizing the hinged fixation between the bottom of the hydraulic cylinder 4 and the frame 1. Through the telescopic reciprocating action of the hydraulic cylinder 4, the first plate 2 can be stably driven to complete the 0-90° tilting action around the first column 23, realizing the switching between the horizontal and vertical states of the curtain wall unit.

[0019] like Figure 5 As shown, the speed control component 5 is used to realize segmented speed control of the flipping stroke, and is matched with the PLC control system to realize automated speed regulation throughout the entire process. The speed control component 5 includes a fifth plate 51, a sleeve 52, a first reflector 53, a second reflector 54, and a laser sensor 55, wherein, as... Figure 6 As shown, a mounting hole 511 is opened on the side wall of the fifth plate 51 off-center. The head of the laser sensor 55 is fixed inside the mounting hole 511 by threaded engagement. The line connecting the axis of the laser sensor 55 and the axis of the fifth plate 51 is parallel to the surface of the first plate 2 to ensure accurate detection angle. A connecting post 512 is integrally formed at the end of the fifth plate 51. A connecting plate 513 is fixed at the end of the connecting post 512. The connecting plate 513 is fixed to the extended end of the first column 23 by bolts, so that the fifth plate 51, the first column 23, and the first plate 2 rotate synchronously. The connecting post 512 effectively increases the distance between the fifth plate 51 and the first U-shaped seat 11, reserving sufficient installation and detection space for the laser sensor 55.

[0020] like Figure 5 As shown, the sleeve 52 is coaxially sleeved on the outside of the fifth plate 51. The two are fitted with a clearance and can rotate relative to each other. One end of the sleeve 52 is fixedly connected to the fixing plate 521, and the fixing plate 521 is fixedly connected to the first U-shaped seat 11, so that the sleeve 52 remains stationary. The other end of the sleeve 52 is fixedly installed with the first reflector 53. The outer side of the first reflector 53 is fixedly attached to the second reflector 54. The two reflectors are coaxially fixed and have no relative displacement. The first reflector 53 has a first through hole 531 and a second through hole 532. Both through holes are arc structures with a single arc central angle of 10°. The two through holes correspond to the starting and ending sections of the flipping, respectively, and the maximum angle between the two through holes is 90°, which is precisely matched with the maximum 90° flipping stroke of the first plate 2.

[0021] like Figure 1As shown, the third plate 3 is vertically positioned above the frame 1 and is parallel to the first plate 2 in the vertical state. A closed positioning interlayer is formed between the two, which can laterally limit the curtain wall unit in the vertical state. A gap is reserved between the third plate 3 and the frame 1. This gap can accommodate the side plate 21 to rotate with the first plate 2, avoid structural interference, and ensure smooth flipping action.

[0022] like Figure 2 As shown, an adjustment unit is provided between the third plate 3 and the frame 1 to adapt to the positioning requirements of different specifications of curtain wall units. The adjustment unit includes a slider 31, a fourth plate 32 and a locking bolt 33. The fourth plate 32 is fixed on the frame 1 and located behind the third plate 3. A rectangular through groove 321 is opened in the middle of the fourth plate 32. The slider 31 is slidably assembled inside the through groove 321. The end of the slider 31 is fixedly connected to the third plate 3, so that the third plate 3 can slide back and forth with the slider 31 to realize the spacing adjustment. A threaded hole 322 extending into the through groove 321 is opened on the side wall of the fourth plate 32. The locking bolt 33 is threadedly assembled in the threaded hole 322. After the adjustment is completed, tightening the locking bolt 33 can press the slider 31 to realize the position locking.

[0023] Working principle: According to the dimensions of the curtain wall unit to be processed, loosen the locking bolt 33, slide the slider 31 back and forth to move the third plate 3, adjust the distance between the third plate 3 and the first plate 2 to match the width of the curtain wall unit, tighten the locking bolt 33 after adjustment to lock the position of the slider 31, and place the curtain wall unit to be flipped horizontally on the horizontal bearing surface of the first plate 2. Power on the equipment and start it up. The PLC control system controls the hydraulic cylinder 4 to extend and drive the first plate 2 to flip upward around the first column 23. In the initial stage of flipping, the laser sensor 55 rotates synchronously with the fifth plate 51. The laser passes through the second through hole 532 and irradiates the second reflector 54. After the control system recognizes the signal, it controls the hydraulic cylinder 4 to run at a low speed to achieve a slow start in the initial 10° range of flipping, avoiding rigid impact. When the flipping angle exceeds the initial 10° slow start range, the laser emitted by the laser sensor 55 is removed. The laser beam passes through the second through hole 532, illuminating the solid area of ​​the first reflector 53. The control system switches the control mode, driving the hydraulic cylinder 4 to extend and retract at high speed, completing the rapid flipping operation of the middle 70° stroke, improving work efficiency. When the first plate 2 flips to a near vertical state, with 10° of stroke remaining, the laser sensor 55 rotates to the corresponding position, and the laser passes through the first through hole 531 to illuminate the second reflector 54. The control system switches to low-speed mode again, and the hydraulic cylinder 4 runs at low speed, completing the final 10° slow flipping until the first plate 2 is in vertical position. The curtain wall unit enters the positioning interlayer formed by the third plate 3 and the first plate 2. After the flipping is completed, external cranes, forklifts, transfer trolleys and other construction equipment can be used to smoothly lift, clamp and connect the vertical curtain wall unit, and transfer the unit from the equipment station to the installation work surface, material stacking area or the next processing station.

[0024] The wiring diagrams of the hydraulic cylinder 4, laser sensor 55, and PLC control system in this invention are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the hydraulic cylinder 4, laser sensor 55, and PLC control system will not be explained in detail.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
