Description

Technical Field

[0001] The utility model relates to the technical field of glass curtain wall construction, in particular to a hoisting device for installing a glass curtain wall. Background Art

[0002] During the installation of the glass curtain wall, it is necessary to lift and install the glass blocks. Some of the existing technologies use lifting brackets to clamp the glass on both side walls, while others use electric suction cups to achieve the lifting operation of the glass by vacuum adsorption. Since electric suction cups are relatively convenient to operate, have firm adsorption, and are compact and easy to install and use, they are mainly used in the actual construction process. However, when using electric suction cups, there are also the following problems: the electric suction cups are usually evenly adsorbed on the middle of the glass to ensure the stability of the glass during the lifting process, but there are no protective measures at the four corners of the glass. During the lifting process, as the height continues to increase, any slight flow of gas will cause the glass to shake significantly, which is easy to cause the fragile four corners to collide and even break, posing certain safety hazards.

If the vacuum suction cup 2 is arranged at the four corners of the support frame 1, the protective corner plates 3 are sleeved outside the vacuum suction cup 2; The cross section of the protective corner plate 3 is a triangular structure, and the adjacent two sides are provided with a receiving groove that is connected to the inside; in addition, each end of the protective corner plate 3 is preferably rounded to improve safety and reduce the adverse effects on external objects during the hoisting process; each protective corner plate 3 is provided with a pulling rope 4, which is wound on a corresponding winding wheel 5, and each winding wheel 5 is rotatably set on the support frame 1; the protective corner plate 3 can be connected to the support frame 1 through the pulling rope 4, thereby avoiding the problem that the protective corner plate 3 is difficult to find after it is separated from the support frame 1, and at the same time, the pulling of the pulling rope 4 is used to realize the auxiliary support of the protective corner plate 3 to the glass, thereby avoiding the direct falling of the glass after the vacuum suction cup 2 loses its function, and further ensuring the safety of the glass during the hoisting process. The setting of the winding drum can store and accommodate the pulling rope 4, and by winding multiple turns of the pulling rope 4 on it, it can meet the use of glass of various sizes, thereby expanding the scope of application of the utility model.

[0021] Furthermore, in this embodiment, each protective corner plate 3 is provided with an adjustable fixed clamping plate 6, which can adjust the spacing inside the protective corner plate 3 to achieve a tight connection with the glass; preferably, a rubber gasket is provided on the fixed clamping plate 6 and the inner wall of the corresponding protective corner plate 3, so as to achieve a tight connection with the glass while avoiding scratches on the glass surface. Specifically, the protective corner plate 3 is threaded with an adjusting screw 7, which is rotatably connected to the fixed clamping plate 6. By rotating the adjusting screw 7, the fixed clamping plate 6 can be moved in the internal space of the protective corner plate 3, thereby completing a tight clamping operation with the glass.

[0022] Furthermore, a hoisting rod 8 is provided at the top of the support frame 1, and a lifting lug 9 is provided at the top of the hoisting rod 8 for connecting with the lifting equipment; a receiving cavity is provided in the hoisting rod 8, and a support rod 10 is provided in the receiving cavity, and a plurality of winding wheels 5 are arranged on the support rod 10 along the vertical direction through a spring; a through slot 11 is provided at a position corresponding to the winding wheel 5 on the side wall of the hoisting rod 8, and the through slot 11 is connected with the receiving cavity, and the pulling rope 4 passes through the through slot 11 and is connected with the protective corner plate 3. The winding wheel 5 can ensure the automatic reset of the protective corner plate 3 after use through the spring, thereby improving the convenience of operation, and can also use the tension of the spring to ensure the tight connection between the protective corner plate 3 and the glass. In addition, in the present embodiment, a fixing sleeve 18 for fixing the pulling rope 4 is provided on the protective corner plate 3. The fixing sleeve 18 is preferably coaxially arranged with the adjusting screw 7, and is internally provided with an internal thread matching the adjusting screw 7. The setting heights of the plurality of fixing sleeves are different. The setting height of each fixing sleeve 18 matches the setting position of the winding wheel 5 corresponding to the pulling rope 4 connected to it, which helps to pull out and reset the pulling rope 4 horizontally, and provides convenience for moving the protective corner plate 3 in and out.

[0023] Furthermore, a positioning member for positioning the winding wheel 5 is elastically arranged in the hoisting rod 8 to ensure the stability of the protective angle plate 3 after the state is adjusted; an adjustment groove 12 communicating with the accommodating cavity is provided on the side wall of the hoisting rod 8, and a plurality of adjustment grooves 12 are preferably arranged at intervals along the circumferential side wall of the hoisting rod 8, and the positioning member is connected to the adjustment part arranged outside the hoisting rod 8 through the adjustment groove 12. By controlling the adjustment part to move upward, the positioning of the winding wheel 5 by the positioning member can be released, so that the protective angle plate 3 can be adjusted normally.

Preferably, in this embodiment, a buffer spring 17 is arranged on the top of the positioning ring 14 at the top, and the buffer spring 17 is sleeved on the outside of the support rod 10, and the top end is connected to the inner wall of the accommodating cavity; in addition, the adjustment ring 13 is connected to the positioning ring 14 at the top through a fixing rod. When the protective angle plate 3 needs to be moved, the adjusting ring 13 can be pulled to drive the positioning ring 14 to move upward, so that the positioning ring 14 is disengaged from the corresponding winding wheel 5. At this time, the buffer spring 17 is in a compressed state. After the protective angle plate 3 is adjusted into place, the adjusting ring 13 is released. Under the restoring force of the buffer spring 17, the positioning ring 14 is re-engaged with the winding wheel 5 for positioning.

[0025] When the utility model is used, the vacuum suction cup 2 is first controlled to be adsorbed on the middle part of the curtain wall glass to be hoisted, and then the adjustment ring 13 is pulled up to release the limit of the winding wheel 5, and then the protective corner plate 3 is pulled to move to the corner of the curtain wall glass, and is set on the four corners of the curtain wall glass to protect the glass corners, and finally the adjustment ring 13 is loosened to reset it, and after the positioning ring 14 achieves contact and positioning with the winding wheel 5, the hoisting can be performed. By protecting the glass corners during the hoisting process, the safety of the glass hoisting process is greatly guaranteed, and the collision and damage of the glass corners during the hoisting process are avoided. The structure is simple and practical.
