Description

Technical Field

[0001] The present invention relates to the technical field of curtain wall glass installation, in particular to a curtain wall glass stable suspension structure for building engineering construction. Background Art

[0002] Curtain walls are the exterior enclosures of buildings. They are non-load-bearing and are hung like a curtain, hence the name "curtain wall." They are lightweight, decorative walls commonly used in modern large and high-rise buildings. Existing curtain wall glass installations typically utilize vacuum suction cups for hoisting, as exemplified by the stable suspension structure for curtain wall glass used in construction projects (publication number CN113772525A) and the high-stability curtain wall glass suspension device used in construction projects (publication number CN216811036U). However, these prior art technologies primarily focus on clamping the curtain wall glass to improve its safety and stability during hoisting, without addressing the issue of suspension stability. Therefore, we propose a stable suspension structure for curtain wall glass used in construction projects. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art, meet actual needs, and provide a stable suspension structure for curtain wall glass for construction engineering to solve the technical problem of insufficient stability of the current curtain wall glass suspension.

[0004] In order to achieve the purpose of the present invention, the technical solution adopted by the present invention is as follows: a stable suspension structure for curtain wall glass used in construction engineering is designed, including a hanger, a suspension rope, a spider glass suction cup, a threading rope, a cross mechanism, an extension mechanism and a strain tube pressure sensor;

[0005] At least one of the hanging ropes pulls the high end of the hanger, the spider glass suction cup is arranged on the front of the hanger, and at least two of the threading ropes are arranged at equal intervals on the back of the hanger parallel to the working surface of the spider glass suction cup, wherein several of the threading ropes are cross-threaded on the back of the hanger through a cross mechanism, and each bending point of the threading rope is connected to the back of the hanger through an extension mechanism. It is worth noting that the extension direction of the extension mechanism is away from the cross mechanism, and the free end of the extension mechanism is arranged with a strain tube pressure sensor threaded on the threading rope.

[0006] Preferably, the cross mechanism includes a wheel seat, a rotating shaft and a guide wheel;

[0007] The wheel seat is movably arranged on the back of the hanger via a rotating shaft in a position relative to the center of the plurality of threading ropes, and at least two guide wheels are rotatably arranged inside the wheel seat in a centrally symmetrical structure;

[0008] Wherein, a plurality of the wire pulleys have a unique intersection in vertical projection.

[0009] Preferably, the surface of the guide wheel is an annular concave structure, and the threading rope is in rolling contact with the guide wheel;

[0010] Among them, a plurality of the threading ropes are arranged crosswise in a gap structure through the guide wheel.

[0011] Based on the above introduction, the two mirror-image cross-drawing ropes in the present invention form a first stress-resisting structure. Specifically, the intersection can form a tensile stress, reducing the swing stress of the curtain wall glass installation part on the drawing rope. The reverse deduction method can be used to demonstrate its effect. In the present invention, the upper and lower parts of the drawing rope are parallel parts, and the middle part is a cross part. Under wind force, the swing amplitude generated by the parallel part is greater than the swing amplitude generated by the cross part. The main reasons are: first, the drawing rope in the parallel part lacks structural energy absorption, and the swing force transmission effect on it is small; second, the drawing rope in the cross part can convert energy with the wire pulley on the one hand, and the wheel seat is movably arranged on the hanger through the rotating shaft, and the swing force is converted into rotational friction. On the other hand, the drawing rope in the cross part is an arc, which has higher tension.

[0012] Preferably, the extension mechanism includes a fixing seat, a cylinder seat, a cylinder, a top plate, a sleeve, a spring and a scissor-type telescopic frame;

[0013] The fixing seat is fixed to the back of the hanger, the cylinder seat is passed through the fixing seat, the cylinder is fixed to the cylinder seat, the top plate is fixed to the telescopic end of the cylinder, the sleeve is passed through the top plate, the spring is arranged parallel to the cylinder and between the sleeve and the cylinder seat, wherein the strain tube pressure sensor is fixed to the sleeve terminal, and the scissor-type telescopic bracket is arranged on the outside of the spring to connect the sleeve and the cylinder;

[0014] It is worth noting that the sleeve, spring, cylinder seat and fixing seat are connected to form a threading channel, and the threading rope is passed through the threading channel.

[0015] Preferably, a guide ring is embedded in the terminal port of the casing, and the guide ring, casing and strain tube pressure sensor are coaxially arranged, and the inner diameter of the guide ring is larger than the diameter of the threading rope, and the inner diameter of the guide ring is smaller than the aperture of the strain tube pressure sensor.

[0016] Preferably, a fixed pulley is fixedly provided at the terminal port of the cylinder seat relative to the deflection direction of the threading rope.

[0017] Preferably, the electrically controlled retractable action of the cylinder responds to a logical operation of a pressure signal in an output signal of the strain tube pressure sensor.

[0018] Based on the above, the sleeve and the drawing rope form a second stress-resisting structure. Specifically, the cylinder extends, pushing the sleeve on the drawing rope away from the cross mechanism, pulling the scissor-type telescopic frame apart. This increases the fixed surface area formed by the hanger and the two drawing ropes, shortening the drawing rope's swinging portion. This effect can be inferred through the effect amplification technique. If the cylinder extends, pushing the sleeve on the drawing rope to move closer to the fixed end of the drawing rope (not connected to the fixed structure at the end of the drawing rope), the drawing rope is equivalent to being threaded through a longer pipe, reducing the amount of rope swing.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention improves the existing curtain wall glass suspension device by introducing two cross-arranged drawing ropes to assist in the stability and safety of the suspension device. The cross-arrangement can form stress resistance at the intersection when the drawing ropes are swung by wind, thereby reducing the swing stress of the curtain wall glass installation portion on the drawing ropes. Compared with the existing technology, the present invention further improves the safety and stability of the curtain wall glass suspension during the hoisting process, which is conducive to promoting the development of curtain wall glass installation technology.

[0021] 2. The present invention also provides retractable extension mechanisms at the four corners of the hanger. By utilizing the retractability of the extension mechanism, when the drawing rope is blown by the wind and swings, the drawing rope is deformed from a vertical state by curvature. Under the sensing of the strain tube pressure sensor, the cylinder extends to push the sleeve on the drawing rope to move away from the cross mechanism, and the scissor-type telescopic frame is pulled apart, thereby increasing the fixed surface area formed by the hanger and the two drawing ropes, shortening the swinging rope segment of the drawing rope, reducing the swing factor, and improving stability.

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0033] A stable suspension structure for curtain wall glass used in building construction, see Figures 1 to 7 , including a hanger 1, a hanging rope 2, a spider glass suction cup 3, a threading rope 4, a crossing mechanism 5, an extension mechanism 6 and a strain tube pressure sensor 7;

[0034] As a preferred embodiment, the present invention adopts two lifting ropes 2 to pull the high end of the hanger 1, the spider glass suction cup 3 is installed on the front of the hanger 1, and the two drawing ropes 4 are arranged at equal intervals on the back of the hanger 1 parallel to the working surface of the spider glass suction cup 3. It is worth noting that the drawing ropes 4 are arranged on the outside of the building in a relatively static gap parallel to the curtain wall surface, one end of which can be connected to the crane for winding the lifting rope 2 to facilitate movement with the crane, and the other end can be movably fixed to the ground or movably installed on the floor frame corresponding to the curtain wall glass, wherein the two drawing ropes 4 are cross-threaded on the back of the hanger 1 through a cross mechanism 5, and each bending point of the drawing rope 4 is connected to the back of the hanger 1 through an extension mechanism 6. It is worth noting that the extension direction of the extension mechanism 6 is away from the cross mechanism 5, and the free end of the extension mechanism 6 is arranged with a strain tube pressure sensor 7 threaded on the drawing rope 4. The present invention improves the existing suspension device for curtain wall glass by introducing two cross-arranged drawing ropes 4 thereon, thereby assisting in the stability and safety of the suspension device. The cross-arrangement can form stress tensile strength at the intersection when the drawing ropes 4 are swung by wind, thereby reducing the swing stress of the curtain wall glass installation portion on the drawing ropes 4. Compared with the existing technology, the present invention further improves the safety and stability of the curtain wall glass during the suspension process, which is conducive to promoting the development of curtain wall glass installation technology.

[0035] One embodiment Figure 1 and Figure 3As shown, to facilitate understanding of how the crossing mechanism 5 realizes the cross arrangement of the plurality of threading ropes 4 on the back of the hanger 1, the present invention further discloses a more specific embodiment of the crossing mechanism 5. The crossing mechanism 5 includes a wheel seat 501, a rotating shaft 502, and a guide pulley 503. The wheel seat 501 is movably arranged on the back of the hanger 1 via the rotating shaft 502 in a position centered relative to the two threading ropes 4. The two guide pulleys 503 are rotatably arranged inside the wheel seat 501 in a centrally symmetrical structure.

[0036] The two guide wheels 503 have a unique intersection in the vertical projection. In this embodiment, the present invention preferably arranges two threading ropes 4 and two guide wheels 503 that match the number of threading ropes 4, but the number of threading ropes 4 is not limited to 3, 4, or more. The threading ropes 4 need to be guided in their crossing direction by the guide wheels 503 arranged symmetrically around the center, so that when the threading ropes 4 are crossed, there is only one intersection point in the vertical projection (actually a gap intersection, such as Figure 3 shown).

[0037] As a preferred embodiment, the surface of the guide wheel 503 is an annular concave structure, which is conducive to the rolling contact of the limiting threading rope 4 on it without getting stuck; wherein, the two threading ropes 4 are arranged crosswise in a gap structure through a corresponding number of guide wheels 503.

[0038] Based on the above introduction, the two mirror-image cross-drawing ropes 4 in the present invention form a first stress resistance structure, specifically: the cross-drawing ropes can form a tensile stress resistance, reducing the swing stress of the curtain wall glass installation part on the cross-drawing ropes 4. Figure 1 As shown, the reverse deduction method can be used to reflect its effect. In the present invention, the upper and lower parts of the drawing rope 4 are parallel parts, and the middle part is a cross part. Under the blowing of wind, the swing amplitude generated by the parallel part is greater than the swing amplitude generated by the cross part. The main reasons are: first, the drawing rope 4 in the parallel part lacks structural energy absorption, and the swing force transmission effect thereon is small; second, the drawing rope 4 in the cross part can, on the one hand, convert energy with the wire wheel 503, and the wheel seat 501 is movably arranged on the hanger 1 through the rotating shaft 502, and the swing force is converted into rotational friction. On the other hand, the drawing rope 4 in the cross part is an arc, and has higher tension.

[0039] One embodiment Figure 4 and Figure 5 As shown, in order to facilitate understanding of how the extension mechanism 6 extends on the threading rope 4 and stabilizes the hanger 1, the present invention also discloses a more specific embodiment of the extension mechanism 6. The extension mechanism 6 includes a fixing seat 601, a cylinder seat 602, a cylinder 603, a top plate 604, a sleeve 605, a spring 606 and a scissor-type telescopic frame 607;

[0040] The fixing base 601 is fixed to the back of the hanger 1, the cylinder base 602 is inserted through the fixing base 601, the cylinder 603 is fixed to the cylinder base 602, the top plate 604 is fixed to the telescopic end of the cylinder 603, the sleeve 605 is inserted through the top plate 604, and the spring 606 is arranged parallel to the cylinder 603 and between the sleeve 605 and the cylinder base 602. Among them, the strain tube pressure sensor 7 is fixed to the terminal end of the sleeve 605, and the scissor-type telescopic bracket 607 is arranged outside the spring 606 to connect the sleeve 605 and the cylinder 603.

[0041] It is worth noting that the sleeve 605, spring 606, cylinder seat 602, and fixed seat 601 are connected to form a threading channel, through which the threading rope 4 is threaded. The electrically controlled retractable movement of the cylinder 603 responds to the logical operation of the pressure signal in the output signal of the strain tube pressure sensor 7. The present invention also arranges a retractable extension mechanism 6 at each of the four corners of the hanger 1. Utilizing the elasticity of the extension mechanism 6, when the threading rope 4 is blown by the wind and swings, the threading rope 4 produces a curvature deformation from its vertical state. Under the sensing of the strain tube pressure sensor 7 (the working principle of the strain tube pressure sensor 7: two or four strain gauges are attached to the cylinder wall, half of which are attached to the solid part as temperature compensation gauges, and the other half as measurement strain gauges. When there is no pressure, the four strain gauges form a balanced full-bridge circuit; when pressure acts on the inner cavity, the cylinder deforms into a "waist drum shape", causing the bridge to lose balance and output a voltage that is proportional to the pressure), the cylinder 603 The extended pushing sleeve 605 moves on the threading rope 4 away from the cross mechanism 5, and the scissor-type telescopic frame 607 is pulled open, thereby increasing the fixed surface area formed by the hanger 1 and the two threading ropes 4 and shortening the swinging rope segment of the threading rope 4. From the perspective of calculus, it can be clearly judged that the swing factor is reduced and the stability is improved; when the threading rope 4 is restored to be coaxial with the sleeve 605 and the strain tube pressure sensor 7, the cylinder 603 retracts and restores the softness of this part of the threading rope 4, which is convenient for the installation of the curtain wall glass. Of course, the distance that the cylinder 603 in the present invention pushes the sleeve 605 to move on the threading rope 4 can be arranged according to actual work requirements and is not limited in the present invention.

[0042] It is noteworthy that a guide ring 608 is embedded within the terminal end of the casing 605. The guide ring 608, casing 605, and strain-tube pressure sensor 7 are coaxially arranged. The inner diameter of the guide ring 608 is larger than the diameter of the threading rope 4, but smaller than the aperture of the strain-tube pressure sensor 7. In the present invention, the guide ring 608 is also embedded within the terminal end of the casing 605. This guide ring 608 improves the coaxiality of the threading rope 4, the casing 605, and the strain-tube pressure sensor 7, preventing minor swings of the threading rope 4 from triggering the strain-tube pressure sensor 7.

[0043] As a preferred embodiment, a fixed pulley 609 is fixedly provided at the terminal end of the cylinder seat 602 relative to the deflection direction of the threading rope 4, which can reduce the wear at the bend of the threading rope 4.

[0044] Based on the above description, the sleeve 605 and the drawing rope 4 form a second stress resistance structure in the present invention. Specifically, the cylinder 603 extends to push the sleeve 605 on the drawing rope 4 to move away from the cross mechanism 5, and the scissor-type telescopic frame 607 is pulled apart, thereby increasing the fixed area formed by the hanger 1 and the two drawing ropes 4 and shortening the swinging rope section of the drawing rope 4. Figure 1 As shown, the effect of this part can be reflected by means of effect amplification. If the cylinder 603 extends to push the sleeve 605 to move the threading rope 4 to a position close to the fixed end of the threading rope 4 (not connected to the fixed structure at the end of the threading rope 4), at this time, the threading rope 4 is equivalent to threading a longer pipe, and the swing amount of the threading rope 4 is reduced.

[0045] In addition, the circuits, electronic components and modules involved in the present invention are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to internal structures and methods.

[0046] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
