Description

Technical Field

[0001] This invention relates to the field of building construction equipment technology, and in particular to an auxiliary device for glass curtain wall hoisting. Background Technology

[0002] In existing technologies, the outer frame dimensions of hoisting fixtures are fixed, limiting their applicability to curtain wall glass of fixed sizes and making timely adjustments difficult based on different curtain wall glass dimensions. Currently, patent CN115650031A discloses a zippered curtain wall glass hoisting and climbing auxiliary device, including a curtain wall glass body. Outer frames are provided at the lower ends of both sides of the curtain wall glass body, with the outer frames shaped like an "L" and fastened to the corners of the curtain wall glass body. The lower ends of two slings are fixedly connected to the two outer frames respectively. The positioning plate is attached from top to bottom to the upper center of the curtain wall glass body; a sliding stop bar is slidably installed on the front of the outer frame, and the sliding stop bar fits against the front of the curtain wall glass body. The beneficial effect is that by setting outer frames at the lower ends of both sides of the curtain wall glass body, the outer frames are "L"-shaped and attached to the corners of the curtain wall glass body, and the upper ends of the two slings are fixed to the lower ends of the slings. When the slings are raised, the two outer frames move closer together under the tension of the slings, thereby achieving the installation and positioning of curtain wall glass bodies of different sizes, effectively increasing the applicability of this device. However, in actual use, this device can only be used for flat glass. Since modern buildings often use curved glass for aesthetic purposes, the above structure cannot be used to fix curved glass. Furthermore, when the width or height of the glass curtain wall decreases, the positioning plate 5 cannot contact the upper surface of the glass curtain wall. Therefore, the problem of not being applicable to glass curtain walls of different sizes is not completely solved.

[0003] A glass curtain wall hoisting auxiliary device is provided, which can clamp curved glass curtain walls and adapt to curved glass curtain walls of different sizes. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a glass curtain wall hoisting auxiliary device, which effectively solves the problems of the prior art, such as its inability to be used for fixing curved glass and its incomplete solution to the problem of adapting to different sizes.

[0005] The technical solution includes a rectangular base plate, with a lower clamping base on each side of the rectangular base plate. The lower clamping base can slide left and right on the rectangular base plate. There is an upper clamping base above each lower clamping base. The distance between the lower clamping base and the upper clamping base can be adjusted. The lower clamping base and the upper clamping base are provided with a first rectangular groove on the side near the center of the rectangular base plate. The left and right edges of the glass curtain wall can be placed in their corresponding first rectangular grooves. The lower clamping base and the upper clamping base can rotate horizontally at the same time. Multiple first rectangular grooves are tightly fitted with the edges of the glass curtain wall to fix the glass curtain wall.

[0006] Furthermore, a sliding groove is provided at each of the left and right ends of the rectangular base plate, and a slider is provided in each sliding groove. The slider can slide left and right in the sliding groove and can be fixed in the direction close to the left and right ends of the rectangular base plate after sliding. A stepped hole is provided on the upper end face of the slider, and a stepped shaft is provided on the lower end face of the lower clamping base. The stepped shaft is rotatably connected to the stepped hole. The lower clamping base can rotate on the slider through the rotational cooperation of the stepped shaft and the stepped hole, and the lower clamping base can drive the slider to move upward together through the cooperation of the stepped shaft and the stepped surface on the stepped hole.

[0007] Furthermore, the upper end face of the lower clamping base is provided with a vertical square post, and the upper end face of the square post is provided with a square blind hole. The lower end face of the upper clamping base is provided with a vertical square sliding post, which can slide up and down in the square blind hole. The upper end of the square post is provided with a threaded hole that passes through the square blind hole. A wing screw is provided in the threaded hole, and the wing screw is threadedly connected to the threaded hole. Rotating the wing screw can press against the square sliding post, so that the upper clamping base can be fixed after sliding.

[0008] Furthermore, a through rectangular opening is provided on both the front and rear side walls of the first rectangular groove, and a clamping slider that can slide back and forth is provided in the rectangular opening. Two clamping sliders in the same first rectangular groove can slide towards each other or away from each other, thereby controlling the clamping or loosening of the glass curtain wall.

[0009] Furthermore, the two sliding grooves penetrate the upper and left and right end faces of the rectangular base plate. The bottom of the sliding grooves is provided with evenly distributed grooves. The slider is provided with a second rectangular groove on one end face near the left and right end faces of the rectangular base plate. The second rectangular groove penetrates the upper and lower end faces of the slider. A support ear is provided above the front and rear side walls of the second rectangular groove. The support ear is located on one side near the left and right end faces of the rectangular base plate. A cylinder is fixed on the inner end face of the support ear. A pawl is rotatably connected to the cylinder. A torsion spring is provided on the cylinder on the front and rear sides of the pawl. The torsion spring keeps the lower end of the pawl in the groove, so that the slider cannot move towards the left and right end faces of the rectangular base plate. Thus, the slider can be fixed in the direction near the left and right end faces of the rectangular base plate after sliding. A pressing block is provided above the pawl. When a force opposite to the direction of the left and right end faces of the rectangular base plate is applied to the pressing block, the bottom of the pawl is disengaged from the groove, so that the slider can move towards the left and right end faces of the rectangular base plate.

[0010] Furthermore, the slider is shaped such that the width of the upper front-to-back direction is smaller than the width of the lower front-to-back direction, thus forming a stepped surface. The groove is shaped such that the opening size of the upper front-to-back direction is smaller than the opening size of the lower front-to-back direction, thus forming a stepped surface. When the slider is placed in the groove, the slider can drive the rectangular base plate to move upward through the cooperation of the stepped surfaces.

[0011] Furthermore, each of the lower clamping base and the upper clamping base has a rectangular boss on one side of the rectangular base plate near the left and right end faces. The rectangular boss has a third rectangular groove that penetrates the upper and lower end faces. The rectangular boss has a through first circular hole on the side of the rectangular base plate near the left and right end faces. A sliding shaft is provided in the first circular hole and can slide left and right in the first circular hole. A first hinge ear is fixedly connected to the side of the sliding shaft near the left and right end faces of the rectangular base plate. A spring is provided on the sliding shaft between the first hinge ear and the outer end face of the rectangular boss. The spring allows the sliding shaft to return to its original position after sliding away from the left and right end faces of the rectangular base plate. A first connecting rod is hinged to the front and rear of each of the first hinge ears. The other ends of the two first connecting rods are hinged to the second connecting rods. The other ends of the two second connecting rods are respectively hinged to the two third connecting rods. The other ends of the two third connecting rods are respectively spherically hinged to the clamping slider.

[0012] Furthermore, a second hinge lug is provided on the front and rear end faces of the lower clamping base and the upper clamping base. The second connecting rod is hinged to the second hinge lug at the middle position. When a force is applied to the sliding shaft away from the left and right end faces of the rectangular base plate, the sliding shaft drives the clamping slider to slide inward through the first connecting rod, the second connecting rod, and the third connecting rod, thereby clamping the glass curtain wall. When the force applied to the sliding shaft is removed, the spring causes the sliding shaft to move towards the left and right end faces of the rectangular base plate to reset, thereby causing the clamping slider to slide outward, thereby releasing the glass curtain wall.

[0013] Furthermore, the third rectangular groove has through-rotation holes on its front and rear side walls, and a rotating shaft is provided in the rotating holes. The rotating shaft can rotate within the rotating holes. A first rope is fixedly connected to the inner end face of the two sliding shafts on the lower clamping base and the upper clamping base. Each first rope passes under the rotating shaft and through the rotating shaft. A second rope is provided in the gap between the rotating shaft and the end face of the lower clamping base and the upper clamping base near the left and right end faces of the rectangular base plate, and the second rope extends upward. Each first rope is fixedly connected to the second rope. When the second rope is pulled upward, a force opposite to the direction of the left and right end faces of the rectangular base plate can be applied to the upper and lower sliding shafts through the first ropes.

[0014] Furthermore, the upper end face of the upper clamping base is provided with a circular blind hole, a first sliding wheel is provided above the circular blind hole, and a circular column is provided at the lower end of the first sliding wheel, which can rotate within the circular blind hole; a second sliding wheel is provided directly above the rectangular base plate, and second ropes at the left and right ends pass through the upper end face of the first sliding wheel and are connected to the second sliding wheel. When the second sliding wheel is pulled upward, it can drive the second rope to be pulled upward.

[0015] Furthermore, the end of the clamping slider facing the inner side of the first rectangular groove is arc-shaped, which can adapt to curved glass curtain walls, and a rubber layer is pasted on one side of the arc-shaped surface to increase the friction during clamping.

[0016] This invention has a clever structure that can clamp curved glass curtain walls and adapt to curved glass curtain walls of different sizes. Attached Figure Description

[0030] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Depend on Figures 1 to 13 The present invention includes a rectangular base plate 1, with a lower clamping base 4 on each side of the rectangular base plate 1. The lower clamping base 4 can slide left and right on the rectangular base plate 1. Each lower clamping base 4 has an upper clamping base 5 above it. The distance between the lower clamping base 4 and the upper clamping base 5 can be adjusted. The lower clamping base 4 and the upper clamping base 5 are provided with a first rectangular groove 6 on the side near the center of the rectangular base plate 1. The left and right edges of the glass curtain wall can be placed in their corresponding first rectangular grooves 6. The lower clamping base 4 and the upper clamping base 5 can rotate horizontally at the same time. Multiple first rectangular grooves 6 are tightly fitted with the edges of the glass curtain wall to fix the glass curtain wall.

[0032] To enable the lower clamping base 4 to slide left and right on the rectangular base plate 1, and to enable the lower clamping base 4 to rotate horizontally, a sliding groove 2 is provided at each of the left and right ends of the rectangular base plate 1. A slider 3 is provided in each sliding groove 2. The slider 3 can slide left and right in the sliding groove 2 and can be fixed in the direction close to the left and right end faces of the rectangular base plate 1 after sliding. A stepped hole 18 is provided on the upper end face of the slider 3, and a stepped shaft 19 is provided on the lower end face of the lower clamping base 4. The stepped shaft 19 is rotatably connected to the stepped hole 18. The lower clamping base 4 can rotate on the slider 3 through the rotatable cooperation of the stepped shaft 19 and the stepped surface on the stepped hole 18. The lower clamping base 4 can drive the slider 3 to move upward together through the cooperation of the stepped shaft 19 and the stepped surface on the stepped hole 18.

[0033] To adjust the distance between the lower clamping base 4 and the upper clamping base 5, and to allow both the lower clamping base 4 and the upper clamping base 5 to rotate horizontally simultaneously, the upper end face of the lower clamping base 4 is provided with a vertical square post 20, and the upper end face of the square post 20 is provided with a square blind hole 21. The lower end face of the upper clamping base 5 is provided with a vertical square sliding post 22, which can slide up and down within the square blind hole 21. The upper end of the square post 20 is provided with a threaded hole 23 that passes through the square blind hole 21, and a wing screw 24 is provided within the threaded hole 23. The wing screw 24 is threadedly connected to the threaded hole 23. Rotating the wing screw 24 can press against the square sliding post 22, so that the upper clamping base 5 can be fixed after sliding.

[0034] In order to ensure that the edge of the glass curtain wall can be firmly fixed in the first rectangular groove 6, a through rectangular opening 7 is provided on the front and rear side walls of the first rectangular groove 6. There is a clamping slider 8 that can slide back and forth in the rectangular opening 7. Two clamping sliders 8 in the same first rectangular groove 6 can slide towards each other or away from each other, thereby controlling the clamping or loosening of the glass curtain wall.

[0035] To prevent the lower clamping base 4 and upper clamping base 5 from shifting to the sides during hoisting, which could cause the glass curtain wall to become loosely fixed, the two sliding grooves 2 penetrate the upper and left and right end faces of the rectangular base plate 1. The bottom of the sliding grooves 2 has evenly distributed grooves 9. The slider 3 has a second rectangular groove 10 on one end face near the left and right end faces of the rectangular base plate 1. The second rectangular groove 10 penetrates the upper and lower end faces of the slider 3. Support ears 11 are located above the front and rear side walls of the second rectangular groove 10, near the left and right end faces of the rectangular base plate 1. A cylinder 12 is fixed to the inner end face of the support ear 11, and a pawl 13 is rotatably connected to the cylinder 12. The pawl 13 has circular grooves on its front and rear sides. A torsion spring 14 is provided on the column 12. The torsion spring 14 keeps the lower end of the pawl 13 in the groove 9, so that the slider 3 cannot move toward the left and right end faces of the rectangular base plate 1. Thus, after sliding, the slider 3 can be fixed in the direction close to the left and right end faces of the rectangular base plate 1. A pressing block 15 is provided above the pawl 13. When a force opposite to the direction of the left and right end faces of the rectangular base plate 1 is applied to the pressing block 15, the bottom of the pawl 13 is disengaged from the groove 9, so that the slider 3 can move toward the left and right end faces of the rectangular base plate 1.

[0036] In order to enable the slider 3 to move the rectangular base plate 1 upward together, the slider 3 is shaped such that the width of the upper front-to-back direction is smaller than the width of the lower front-to-back direction, forming a stepped surface 16. The slide groove 2 is shaped such that the opening size of the upper front-to-back direction is smaller than the opening size of the lower front-to-back direction, forming a stepped surface 17. When the slider 3 is placed in the slide groove 2, the slider 3 can move the rectangular base plate 1 upward through the cooperation of the stepped surface 16 and the stepped surface 17.

[0037] To achieve simultaneous sliding of the two clamping sliders 8 within the same first rectangular groove 6, thus clamping the glass curtain wall, a rectangular boss 25 is provided on the left and right end faces of both the lower clamping base 4 and the upper clamping base 5 near the left and right end faces of the rectangular base plate 1. A third rectangular groove 26 is provided on the rectangular boss 25, penetrating the upper and lower end faces. A first circular hole 27 is provided on the end face of the rectangular boss 25 near the left and right end faces of the rectangular base plate 1. A sliding shaft 28 is provided within the first circular hole 27, allowing it to slide left and right within the first circular hole 27. A first hinge ear 29 is fixedly connected to the left and right end faces of the rectangular base plate 1. A spring 30 is provided on the sliding shaft 28 between the first hinge ear 29 and the outer end face of the rectangular boss 25. The spring 30 enables the sliding shaft 28 to return to its original position after sliding away from the left and right end faces of the rectangular base plate 1. A first connecting rod 31 is hinged to the front and rear of the first hinge ear 29. The other end of the two first connecting rods 31 is hinged to the second connecting rod 32. The other end of the two second connecting rods 32 is hinged to the two third connecting rods 33 respectively. The other end of the two third connecting rods 33 is spherically hinged to the clamping slider 8 respectively.

[0038] The lower clamping base 4 and the upper clamping base 5 each have a second hinge ear 34 on their front and rear end faces. The second connecting rod 32 is hinged to the second hinge ear 34 at its middle position. When a force is applied to the sliding shaft 28 away from the left and right end faces of the rectangular base plate 1, the sliding shaft 28 drives the clamping slider 8 to slide inward through the first connecting rod 31, the second connecting rod 32, and the third connecting rod 33, thereby clamping the glass curtain wall. When the force applied to the sliding shaft 28 is removed, the spring 30 causes the sliding shaft 28 to move towards the left and right end faces of the rectangular base plate 1 to reset, thereby causing the clamping slider 8 to slide outward, thereby releasing the glass curtain wall.

[0039] To control the movement of the two clamping sliders 8 within the first rectangular groove 6, the third rectangular groove 26 has through-rotation holes 35 on its front and rear side walls. A rotating shaft 36 is installed within the rotating holes 35 and can rotate within them. A first rope 37 is fixedly connected to the inner end faces of the two sliding shafts 28 on the lower clamping base 4 and the upper clamping base 5. Each first rope 37 passes under and through the rotating shaft 36. A second rope 38 is installed in the gap between the rotating shaft 36 and one end face of the lower clamping base 4 and the upper clamping base 5 near the left and right end faces of the rectangular base plate 1, and the second rope 38 extends upward. Each first rope 37 is fixedly connected to the second rope 38. When the second rope 38 is pulled upward, the first rope 37 can simultaneously apply a force to the upper and lower sliding shafts 28 in the opposite direction to the left and right end faces of the rectangular base plate 1.

[0040] To facilitate lifting and to clamp the glass curtain wall during lifting, the upper clamping base 5 has a circular blind hole 39 on its upper end face. A first sliding wheel 40 is provided above the circular blind hole 39, and a circular column 41 is provided at the lower end of the first sliding wheel 40. The circular column 41 can rotate within the circular blind hole 39. A second sliding wheel 42 is provided directly above the rectangular base plate 1. The second ropes 38 at the left and right ends pass through the upper end face of the first sliding wheel 40 and are connected to the second sliding wheel 42. When the second sliding wheel 42 is pulled upward, it can drive the second ropes 38 to be pulled upward.

[0041] The clamping slider 8 has an arc-shaped end facing the inner side of the first rectangular groove 6, which can adapt to curved glass curtain walls. A rubber layer is pasted on one side of the arc shape to increase the friction during clamping.

[0042] In use, this invention first applies a force to the pressing block 15 in the opposite direction to the left and right end faces of the rectangular base plate 1, causing the bottom of the pawl 13 to disengage from the groove 9. The slider 3 is then adjusted to its left and right position on the rectangular base plate 1. Next, the height of the upper clamping base 5 is adjusted using the wing screw 24 to accommodate the dimensions of the curved glass curtain wall to be hoisted. The curved glass curtain wall is then placed in a suitable position on the rectangular base plate 1. The sliders 3 on the left and right sides are then moved, causing the sliders 3 to move the lower clamping base 4 and the upper clamping base 5 towards the center until the first... The left and right end faces of a rectangular groove 6 abut against the curved glass curtain wall. At this time, the second sliding wheel 42 is pulled upward. The second sliding wheel 42 drives the sliding shaft 28 on the lower clamping base 4 and upper clamping base 5 on the left and right sides to slide away from the left and right end faces of the rectangular base plate 1 through the first rope 37 and the second rope 38. At this time, the sliding shaft 28 drives the clamping slider 8 on the front and rear sides to slide inward simultaneously through the first connecting rod 31, the second connecting rod 32, and the third connecting rod 33 until the curved glass curtain wall is clamped, preventing the glass curtain wall from tilting during movement. Continue to stretch the second sliding wheel 42, and then apply an upward stretching force to the lower clamping base 4 and the upper clamping base 5 through the second rope 38, the first rope 37, the sliding shaft 28, and the rotating shaft 36. Then, the lower clamping base 4 can make the slider 3 receive an upward stretching force through the cooperation of the step shaft 19 and the step surface on the step hole 18. The slider 3 can make the rectangular base plate 1 receive an upward stretching force through the cooperation of the step surface 16 and the step surface 17. Thus, the rectangular base plate 1 can apply an upward thrust to the glass curtain wall, so as to achieve the purpose of hoisting. During the hoisting process, the cooperation of the pawl 13, torsion spring 14, and groove 9 ensures that the slider 3 will not move to the left or right ends of the rectangular base plate 1, thus ensuring the reliability of the hoisting. After the glass curtain wall is hoisted to the appropriate position, the second sliding wheel 42 is released. At this time, the sliding shaft 28 receives the force of the spring 30, causing the sliding shaft 28 to slide towards the left and right ends of the rectangular base plate 1. Then, the sliding shaft 28 is hinged through the first connecting rod 31, the second connecting rod 32, and the third connecting rod 33, which drives the clamping sliders 8 on the front and rear sides to slide outwards simultaneously until the curved glass curtain wall is released. At the same time, when the pressing block 15 is subjected to a force opposite to that on the left and right ends of the rectangular base plate 1, the bottom of the pawl 13 is disengaged from the groove 9, causing the slider 3 to slide towards the left and right ends of the rectangular base plate 1. This causes the lower clamping base 4 and the upper clamping base 5 to disengage from the curved glass curtain wall, and the curved glass curtain wall is removed from the rectangular base plate 1 and placed in the use position.

[0043] The present invention has the following advantages: 1. The present invention, through the rotation of the lower clamping base 4 on the slider 3, ensures that when the glass curtain wall can be placed in the first rectangular groove 6, the left and right end faces of the curved glass curtain wall are always in perpendicular contact with the left and right end faces inside the first rectangular groove 6. When the clamping sliders 8 on both sides move inward at the same time, since the end of the clamping slider 8 facing the inside of the first rectangular groove 6 is arc-shaped, it can adapt to the curved glass curtain wall to clamp it. 2. The present invention enables the device to adapt to curved glass curtain walls of different sizes by adjusting the left and right sliding of the slider 3 and the up and down adjustment of the upper clamping base 5.

[0044] In summary, this invention employs two symmetrically distributed lower clamping bases 4 and corresponding upper clamping bases 5. When it is necessary to clamp the curved glass curtain wall, the two lower clamping bases 4 and the two upper clamping bases 5 move closer to the center of the rectangular base plate 1 to achieve clamping. At the same time, the lower clamping bases 4 and the upper clamping bases 5 can rotate on their respective horizontal planes, thus ensuring that the inner wall of the first rectangular groove 6 is in close contact with the four edges of the curved glass curtain wall, thereby achieving the clamping of the curved glass curtain wall.
