Description

Technical Field

[0001] This utility model belongs to the technical field, specifically relating to a large-size exterior window glass hoisting device. Background Technology

[0002] Windows allow sunlight to enter a room, bringing light and warmth. They are becoming an increasingly important component of buildings. Designing windows to be larger and more stylish not only improves indoor lighting but also enhances the building's aesthetic appeal.

[0003] After the overall building structure is completed, the exterior window glass is installed. Larger exterior window glass is suitable for hoisting into place using a truck crane. However, due to insufficient floor spacing or insufficient ground area, there is a high probability that truck cranes cannot be used for this purpose. The limited space between floors makes the hoisting of large glass panes and ensuring their safety key challenges in the construction process.

[0004] Existing technologies also involve installing hoisting equipment within a floor, typically on a floor above the construction floor. A winch is used to control the hoisting wires to lift the glass to the construction floor. This method involves a large suspension length of the wire rope, making the glass prone to swaying during installation and posing a high construction risk. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a hoisting device that enables the installation of exterior window glass on the construction floor, offering good hoisting stability and high safety.

[0006] The technical solution adopted by this utility model to solve the aforementioned problem is:

[0007] A large-size exterior window glass hoisting device includes:

[0008] The support frame is composed of an upper platform, a lower platform, and columns that are fixedly connected together.

[0009] The upper pressure plate is installed on top of the support frame, and its top surface abuts against the floor slab.

[0010] The pressure plate is installed at the bottom of the support frame, and its bottom surface abuts against the floor slab.

[0011] The cantilever beam is installed on the upper platform, with a front guide wheel at the front end and a rear guide wheel at the rear end.

[0012] The steel wire rope is installed inside the cantilever beam. Its hoisting end extends downward from the front guide wheel and its lower end is connected to the outer window glass. Its braking end extends downward from the rear guide wheel and its lower end is connected to the winch.

[0013] The drive motor is mounted on the lower platform, and its output shaft is connected to the winch drive.

[0014] Compared with the prior art, the advantages of this utility model with the above structure are:

[0015] This invention uses an upper and lower pressure plate to reliably fix the hoisting equipment to the construction layer; the lifting of the wire rope is controlled by a motor, making construction convenient and easy to control.

[0016] As a preferred option, a further technical solution to the above structure is:

[0017] A bearing seat is provided on the front side of the drive motor, and a shaft hole is provided on the bearing seat. A connecting shaft is installed in the shaft hole. A coupling is fixedly connected to one end of the connecting shaft near the drive motor. The coupling is connected to the output shaft of the drive motor. The other end of the connecting shaft is fixedly connected to the winch. The lower end of the bearing seat is connected to a sliding seat. A through sliding hole is provided at the lower part of the sliding seat. A fixed seat is provided on the side of the sliding seat and fixedly connected to the lower platform. A sliding rod is fixedly connected to the side of the fixed seat. The sliding rod passes through the sliding hole. The sliding seat and the sliding rod are slidably connected.

[0018] The beneficial effects obtained from the above features are: this example can control the motor's transmission to the winch as needed, making it convenient for operators to adjust the equipment.

[0019] A first bevel gear is also fixedly connected to the output shaft of the drive motor. The first bevel gear meshes with a second bevel gear. The center of the second bevel gear is fixedly connected to a transmission shaft. The upper end of the transmission shaft extends through to the upper platform. The end of the transmission shaft that protrudes from the surface of the upper platform is fixedly connected to a flat gear. The flat gear meshes with a rack. The rack is fixedly connected to the side of the cantilever beam.

[0020] The beneficial effects obtained from the above features are: in this example, the cantilever beam is controlled by a motor to achieve a larger cantilever length, thus avoiding collisions between the glass and the lower building and improving construction safety.

[0021] The upper platform has a first bushing embedded inside, and the lower platform has a second bushing installed inside. The drive shaft is slidably connected to the first and second bushings. The lower end of the second bushing is fixed to a tray, and a heavy-duty universal ball is embedded on the surface of the tray. The lower end of the drive shaft rests on the heavy-duty universal ball. A control panel is set on the second bushing. The control panel is fixed to the drive shaft. A support frame is also set. The lower end of the support frame is connected to a pin on the surface of the lower platform. The pin is located below the control panel, and the top of the support frame abuts against the control panel.

[0022] The beneficial effects obtained from the above features are: this scheme adjusts the object driven by the motor, and one motor can perform multiple functions.

[0023] A limit block is fixed to the side of the upper platform. The limit block includes two symmetrically arranged ear plates. Two positioning shafts are fixed in parallel between the two ear plates. The steel wire rope braking end changes direction from the rear guide wheel downward and passes between the two positioning shafts.

[0024] The beneficial effects obtained from the above features are: in this example, the tension block avoids friction between the wire rope and the support frame, reducing wire rope wear.

[0025] The upper pressure plate is connected to the support frame via a telescopic sleeve. The telescopic sleeve includes a rotating seat fixed to the support frame, a sleeve rotatably connected to the rotating seat, and a screw threaded inside the sleeve. The top of the screw is fixed to the upper pressure plate.

[0026] The beneficial effect obtained from the above features is that this example uses a telescopic sleeve to adjust the pressure between the upper pressure plate and the floor slab, ensuring the stability of the support frame.

[0027] The cantilever beam is also equipped with a pressure groove, which is a U-shaped steel that is fastened to the outside of the cantilever beam and fixedly connected to the upper platform at the lower end.

[0028] The beneficial effects obtained from the above features are: In this example, the U-shaped steel effectively restrains the cantilever beam, preventing it from tilting downwards when the front end of the cantilever beam is under great stress, thus improving equipment safety.

Detailed Implementation

[0039] The present invention will be further described below with reference to embodiments, the purpose of which is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0040] See Figures 1 to 9 This utility model provides a large-size exterior window glass hoisting device, comprising:

[0041] Support frame 1 is formed by connecting an upper platform 101, a lower platform 102 and columns.

[0042] The upper pressure plate 2 is installed on the top of the support frame 1, and its top surface abuts against the floor slab.

[0043] The pressure plate 3 is installed at the bottom of the support frame 1, and its bottom surface abuts against the floor slab.

[0044] The cantilever beam 4 is installed on the upper platform 101, with a front guide wheel 12 at the front end and a rear guide wheel 13 at the rear end.

[0045] The steel wire rope 5 is installed inside the cantilever beam 4. Its hoisting end extends downward from the front guide wheel 12 and its lower end is connected to the outer window glass. Its braking end extends downward from the rear guide wheel 13 and its lower end is connected to the winch 6.

[0046] The drive motor 7 is mounted on the lower platform 102, and its output shaft is connected to the winch 6 for transmission.

[0047] The drive motor 7 controls the winch 6 to rotate, thereby releasing or retrieving the wire rope 5. The wire rope 5 is supported by the cantilever beam 4, with the hoisting end extending outside the building and connecting to the glass placed on the ground. When the wire rope 5 is retrieved, it moves the glass upward. When the hoisting end is retrieved to the position of the front guide wheel 12 of the cantilever beam 4, the glass reaches the construction floor for installation. During installation, the hoisting end of the wire rope 5 is very close to the glass, which can stably control the glass and prevent swaying during installation.

[0048] Alternatively, a bearing seat is provided on the front side of the drive motor 7, and a shaft hole is provided on the bearing seat. A connecting shaft 23 is installed in the shaft hole. A coupling 16 is fixedly connected to one end of the connecting shaft 23 near the drive motor 7. The coupling 16 is connected to the output shaft of the drive motor 7. The other end of the connecting shaft 23 is fixedly connected to the winch 6. The lower end of the bearing seat is connected to the sliding seat 18. The lower part of the sliding seat 18 is provided with a through sliding hole. A fixed seat 17 is provided on the side of the sliding seat 18 and is fixedly connected to the lower platform 102. A sliding rod 19 is fixedly connected to the side of the fixed seat 17. The sliding rod 19 passes through the sliding hole. The sliding seat 18 and the sliding rod 19 are slidably connected.

[0049] In this design, a key is provided at the front end of the output shaft of the drive motor 7, and a keyway is provided on the inner wall of the coupling 16. When the coupling 16 is mounted on the output shaft, it can be driven by the drive motor 7. When the coupling 16 is separated from the output shaft, the transmission relationship is resolved. The sliding seat 18 drives the shaft seat to move back and forth. The shaft seat supports the coupling 16 and the winch 6 to move back and forth synchronously. The fixed seat 17 serves as the basis for the movement of the sliding seat 18. The sliding seat 18 is controlled to move back and forth by pulling the switch.

[0050] Alternatively, the pull switch includes a rocker arm 20 and a connecting rod 21. The lower end of the rocker arm 20 is hinged to the fixed base 17, the upper end of the connecting rod 21 is hinged to the middle of the rocker arm 20, and the lower end is hinged to the sliding base 18. By pushing the upper end of the rocker arm 20, the connecting rod 21 is moved, and the lower end of the connecting rod 21 pulls the sliding base 18 to move. Specifically, the upper ends of the opposite sides of the fixed base 17 and the sliding base 18 are provided with mounting grooves, and shafts are installed in the mounting grooves. The lower ends of the rocker arm 20 and the connecting rod 21 are respectively fixed with shaft tubes 22, which are movably fitted outside the shafts.

[0051] Alternatively, a first bevel gear 15 is also fixedly connected to the output shaft of the drive motor 7. The first bevel gear 15 meshes with a second bevel gear 9. The center of the second bevel gear 9 is fixedly connected to a transmission shaft 8. The upper end of the transmission shaft 8 extends through to the upper platform 101. The end of the transmission shaft 8 that protrudes from the surface of the upper platform 101 is fixedly connected to a spur gear 10. The spur gear 10 meshes with a rack 11. The rack 11 is fixedly connected to the side of the cantilever beam 4.

[0052] The drive motor 7 can also control the cantilever beam 4 to extend further out of the building, so that the hoisting end of the wire rope 5 and the hoisted glass maintain a safe distance from the building during the lifting process, avoiding collision between the glass and the building; the drive motor 7 can control the cantilever beam 4 to retract, so that the glass moves horizontally to the position of the building's exterior window.

[0053] Alternatively, a first bushing is embedded inside the upper platform 101, and a second bushing 26 is installed inside the lower platform 102. The drive shaft 8 is slidably connected to the first bushing and the second bushing 26. The lower end of the second bushing 26 is fixed to a tray, and a heavy-duty universal ball is embedded on the surface of the tray. The lower end of the drive shaft 8 rests on the heavy-duty universal ball. A control panel 14 is provided on the second bushing 26. The control panel 14 is fixed to the drive shaft 8. A support frame 25 is also provided. The lower end of the support frame 25 is connected to a pin on the surface of the lower platform 102. The pin is located below the control panel 14, and the top of the support frame 25 abuts against the control panel 14.

[0054] Optionally, the first bushing and the second bushing 26 are tubes with smooth inner walls that are movable and fit with the drive shaft 8, or tubes with balls embedded in the inner wall. The drive shaft 8 can rotate within the first bushing and the second bushing 26, and can also move up and down. The surface of the tray is rotatably fitted with the bottom surface of the drive shaft 8 through a heavy-duty universal ball joint. The control panel 14 is fixed to the drive shaft 8 and rotates synchronously when the drive shaft 8 rotates. The control panel 14 is equivalent to a handle for controlling the up and down movement of the drive shaft 8. It is used to lift the control panel 14 upwards, and then the support frame 25 is erected to support the height position of the control panel 14. At this time, the second bevel gear 9 is displaced upwards and thus separates from the first bevel gear 15, solving the transmission problem caused by the drive motor 7.

[0055] Alternatively, a limit block is fixed to the side of the upper platform 101. The limit block includes two symmetrically arranged ear plates 28, and two positioning shafts 27 are fixed side by side between the two ear plates 28. The braking end of the wire rope 5 changes direction downward from the rear guide wheel 13 and passes between the two positioning shafts 27. The limit block avoids friction between the wire rope 5 and the support frame 1, reducing wear on the wire rope 5.

[0056] Alternatively, the upper pressure plate 2 is connected to the support frame 1 via a telescopic sleeve. The telescopic sleeve includes a rotating seat fixed to the support frame 1, a sleeve rotatably connected to the rotating seat, and a screw threaded inside the sleeve. The top of the screw is fixed to the upper pressure plate 2. The pressure between the upper pressure plate 2 and the floor ceiling is adjusted by the telescopic sleeve to ensure the stability of the support frame 1.

[0057] Alternatively, a pressure groove is also provided on the outside of the cantilever beam 4. The pressure groove is made of U-shaped steel and is fastened to the outside of the cantilever beam 4, with its lower end fixedly connected to the upper platform 101. The U-shaped steel effectively restrains the cantilever beam 4, preventing it from tilting downwards when the front end of the cantilever beam is under great force, thus improving equipment safety.

[0058] When using this utility model, 1) first transport the support frame 25 to the construction floor, and then fix the support frame 1 in the floor using the upper pressure plate 2 and the lower pressure plate 3 to prevent the frame from tilting during hoisting; 2) adjust the rocker arm 20 to tilt outwards towards the support frame 25, so that the sliding seat 18 is away from the fixed seat 17, and the coupling 16 is separated from the output shaft of the drive motor 7; adjust the support frame 25 to be laid down, so that the second bevel gear 9 is engaged with the first bevel gear 15; 3) start the drive motor 7, the transmission shaft 8 rotates, and the flat gear 10. Engage rack 11 to move cantilever beam 4 outwards, and stop drive motor 7 when it is in position; 4) Move drive shaft 8 upwards and fix the position of drive shaft 8 through support frame 25, then push rocker arm 20 inwards to make sliding seat 18 fit with fixed seat 17, coupling 16 is connected to the output shaft of drive motor 7, start drive motor 7 to control the lifting of wire rope 5, and lift glass to the construction layer height; 5) Switch drive motor 7 to drive shaft 8 again, and cantilever beam 4 drives glass to the installation position.

[0059] The beneficial effects of this utility model are:

[0060] This solution uses a modular steel structure support frame with soft bracing pads, allowing for real-time position adjustment indoors. Cantilever beams are used to adjust the equipment's extension length for hoisting heavy glass. The solution also uses motor-controlled cantilever beams and wire ropes, enabling multiple units to be deployed simultaneously via a linkage adjustment mechanism, thus reducing the load-bearing capacity requirements on the floor slab of the hoisting room.

[0061] The above description is only a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
