Description

Technical Field

[0001] The utility model relates to the technical field of building curtain wall hoisting, in particular to a simple building hoisting tool. Background Art

[0002] At present, during the decoration and renovation construction phase, the curtain wall glass needs to be hoisted and installed when the glass curtain wall is installed. However, there is only one pulley on the existing hoisting frame. Using a single pulley to move the frame may cause the glass to shift and collide, resulting in frequent collisions between the top and bottom glass and difficulty in hoisting during the glass hoisting process. In addition, workers are now paid high wages and work teams focus on efficiency, so some insulation walls and window corners near windows may be broken during the hoisting process. Later, workers use hoisting ropes to repair them, and small problems become big problems. When in use, the hoisting frame mostly relies on the rear counterweight to ensure stability during suspension. This setting facilitates circumferential movement of the frame centered on the counterweight, but there are still limitations in forward and backward movement, which can easily make it difficult to move forward, backward, left, and right, thereby burdening the movement of the frame and making it inconvenient to change its position.

[0003] In the prior art, a Chinese utility model with a publication number of CN220449629U and a publication date of February 6, 2024, discloses a small vertical lifting device for use in curtain wall installation projects.

Although the patent is convenient to move and can be dragged and moved by a single person, and is easy to disassemble, after removing the connecting bolts, it can be placed in a construction elevator for vertical transportation, greatly improving construction production efficiency. However, due to its limitations, when the hoisting position needs to be adjusted, the entire device needs to be moved, which is time-consuming and labor-intensive, affecting the hoisting efficiency.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figure 1 and Figure 2As shown, Example 1 is a simple construction hoisting tool, including a diagonal bracing beam 7 and a base, a support frame is connected to one side of the upper part of the base, a winch 18 is provided on the other side of the upper part of the base, one end of the diagonal bracing beam 7 is connected to the side of the base close to the winch 18, and the other end of the diagonal bracing beam 7 is connected to the upper part of the support frame, the diagonal bracing beam 7 is connected to the support extension frame, and the support extension frame is connected to at least two pulley groups that cooperate with the winch 18. The winch 18 is an existing winch, and the type and model of the winch can be selected according to the actual lifting situation, and there is no restriction here. The diagonal bracing beam 7 is connected to the support extension frame, and at least two pulley groups are provided on the support extension frame. The steel wire on the winch 18 can be selected to cooperate with pulley groups in different positions, so that the lifting position can be adjusted without changing the position of the device, avoiding the problem of repeatedly moving the device and improving the lifting efficiency. An anti-top impact travel switch 19 is installed on the support frame to cooperate with the winch 18. The anti-top impact travel switch 19 is an existing travel switch, which can avoid damage to the glass caused by top impact during the lifting process, further protect the glass curtain wall, and improve safety during lifting.

[0020] In this embodiment, the rope pulley assembly includes a symmetrically arranged first wheel 1 and a symmetrically arranged second wheel 2. The two first wheels 1 are connected to the support extension frame, and the two second wheels 2 are located between the two first wheels 1. A rotating shaft is rotatably connected between the two second wheels 2. A connecting rod 3 is provided in the middle of the rotating shaft, and the connecting rod 3 is connected to the middle of the support extension frame. The first wheel 1 is provided with an annular groove 1 for cooperating with the wire rope on the hoist 18, and the second wheel 2 is provided with an annular groove 2 for cooperating with the wire rope on the hoist 18. The bottoms of the annular grooves 1 and 2 are twill-grained frosted bottoms, which are used to increase the friction between the wheels and the wire rope and prevent friction caused by the wire rope cooperating with the wheels. Providing grooves on the rope pulleys can prevent the wire rope from deviating during the lifting process, affecting the lifting effect, and avoid damage to the glass curtain wall caused by problems with the device itself. The two first wheels 1 cooperate with the two second wheels 2 to form four different positions.

[0021] In this embodiment, the support extension frame includes a main beam 6 and a transverse beam 4. The main beam is connected to the diagonal support beam 7 and is an integral structural beam with the diagonal support beam 7. The middle part of the transverse beam 4 is vertically connected to the main beam 6. Both ends of the transverse beam 4 are connected to an oblique reinforcement rod 5 connected to the main beam 6. The transverse beam 4 is a U-shaped structural beam. The upper part of the two ends of the U-shaped structural beam is connected to a rotating shaft, and the first wheel 1 is rotatably connected to the rotating shaft. The U-shaped structural beam and the diagonal support beam 7 are located on the same plane, so that the opening of the U-shaped structural beam is set obliquely upward, and then the wheel is located at the top of the device, which facilitates the rotation of the wheel and avoids the influence of the device during the wire rope hoisting process. The rotating shaft is coaxially installed with the rotating shaft to ensure that the first wheel 1 and the second wheel 2 are at the same height when in use.

[0022] like Figure 1 and Figure 2 As shown, embodiment 2 is a simple building hoisting tool, wherein the support frame includes a main column 9, the lower part of the main column 9 is connected to the base, the middle part of the main column 9 is connected to a diagonal brace 8, and the diagonal brace 8 is connected to the support extension frame.

One end of the central connector 11 is connected to a connecting lug 12, which is fixedly connected to the middle of the diagonal bracing beam 7. The other end of the central connector 11 is connected to a connecting lug 2 13, which is fixedly connected to the base. The central connector 11 can be a steel wire rope or a rod. The central connector 11 connected to the base is provided in the middle of the diagonal bracing beam 7.

The triangular structure is employed in many locations throughout the entire device, further enhancing the device's stability.

[0023] In this embodiment, the base includes a T-frame 14 and an extension frame 16. The middle part of the T-frame 14 is connected to a symmetrically arranged oblique reinforcement rod 15. The extension frame 16 is connected to the T-frame 14, and a winch 18 is arranged on the extension frame 16. The extension frame 16 is a frame frame with several reinforcement rods in the middle part of the frame frame. The extension frame 16 is used to place the winch 18, and can also be used to place counterweights and undertake the transportation of glass curtain walls. The end of the wire rope on the winch 18 is provided with a hook, and the lower part of the base is provided with a running wheel 17. The running wheel 17 can be a self-locking universal wheel or a pulley. The winch 18 cooperates with the device to lift the glass curtain wall.

After the lifting is completed or the extension frame 16 is filled with glass curtain walls, the glass curtain wall is placed to the designated location by the moving device, which makes the transfer more convenient.

[0024] The other structures are the same as those in Example 1.

[0025] Specifically, the main structure is constructed from 100mm × 50mm × 5mm steel square tubes, welded together sequentially according to the structure to form the base for the hoist. After the base is fabricated, the corresponding pulleys are welded to the base for easy relocation. A 160mm × 80mm × 6mm steel square tube is welded together to form the support frame. A rope pulley, acting as a fixed pulley, is placed on top of the steel square tubes and secured with a latch as a pivot. The welded front bracket is secured to the base with 24mm diameter pins. Above the front bracket and base, 100mm × 50mm × 5mm steel square tubes are secured with 24mm diameter pins. Two 50mm × 50mm × 5mm steel pipes are installed at the rear of the hoisting equipment to ensure stability. An anti-overburst limit switch is installed on the support frame to prevent the hoisting unit from collapsing and falling. An 11mm diameter steel wire rope is lowered from the fixed pulley at the boom support frame. The connection nodes of the overall hoisting equipment are reviewed to ensure that the welds are full and leak-free and that the bolts are tightened before commissioning. The materials used are readily available and low-cost, making it highly efficient, easy to manufacture, and simple to operate for curtain wall glass hoisting. The device is reusable and virtually non-wasteful.
