Description

Technical Field

[0001] This invention relates to the field of construction suspended platform technology, specifically a building construction operation platform. Background Technology

[0002] A suspended platform is a high-altitude construction work platform commonly used for curtain wall installation, maintenance, and cleaning. In use, the suspended platform is connected to a cantilever mechanism (installed inside the building) via cables, allowing it to move up and down along the building's exterior facade, providing a platform for workers. However, in practical applications, we have found that existing suspended platforms still have certain shortcomings, such as:

[0003] In existing technologies, suspended platforms are generally suspended directly in the air without contact with the building facade. This makes the suspended platforms very prone to swaying (affected by weather factors such as strong winds, as well as the activities of the workers themselves), which not only affects normal construction, but also affects the stability of the workers standing inside the suspended platform.

[0004] Installing guide devices on the building facade is impractical, as it is not only troublesome to construct but also a "disposable consumable" with high costs. Summary of the Invention

[0005] (1) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a building construction operation platform that features stable lifting and anti-swaying capabilities.

[0007] (II) Technical Solution

[0008] To achieve the aforementioned goals of stable lifting and anti-swaying, the present invention provides the following technical solution: a building construction work platform, including a suspended platform, and further comprising:

[0009] The U-shaped plate is fixedly installed on the side of the suspended platform, and the opening is equipped with casters for rotation.

[0010] The guide rail has suction cups evenly distributed on the side facing away from the basket, and wheel grooves for the movement of the moving wheels are opened on the side facing the basket.

[0011] A mounting block is fixedly installed on the side of the guide rail. The mounting block is connected to a float that is movably installed in the side cabinet via a connecting rod. The side cabinet is fixedly installed on the hanging basket. An upper spring is installed between the float and the inner top wall of the side cabinet, and a lower spring is installed between the float and the inner bottom wall.

[0012] As a preferred embodiment of the present invention, the suction cup is used to adsorb and fix the guide rail to the exterior of the building.

[0013] An inflation mechanism is provided at both the upper and lower ends of the wheel groove. When the moving wheel moves to the upper and lower ends of the wheel groove, the inflation mechanism can inflate the suction cup.

[0014] As a preferred technical solution of the present invention, the inflation mechanism includes an inclined pressure block, a piston, a support spring, an inflation pipe, an air supply pipe, a branch pipe and a one-way valve. An inclined pressure block is movably and telescopically arranged on the inner wall at both ends of the wheel groove. The inclined pressure block is fixedly installed on the piston. The piston is movably arranged in the air cavity opened in the guide rail, and a support spring is fixedly arranged between the piston and the inner wall of the air cavity.

[0015] Both air chambers are connected to an air supply pipe embedded in the guide rail via an inflation pipe, and the air supply pipe is connected to the suction cup via a branch pipe.

[0016] A one-way valve is provided on the inflation tube to allow the gas in the air chamber to be discharged in one direction, and a one-way air inlet tube is also provided on the inner wall of the air chamber.

[0017] As a preferred embodiment of the present invention, both the upper and lower inclined pressure blocks are provided with inclined surfaces, and the two inclined surfaces are inclined in opposite directions.

[0018] As a preferred embodiment of the present invention, the one-way valve includes a valve body, a frustum-shaped valve core, a clamping spring, a sealing ring, and a conical groove. The valve body is fixedly mounted on the inflation tube. The frustum-shaped valve core is movably mounted in the valve body. The frustum-shaped valve core is clamped to the conical groove of the sealing ring by the clamping spring. The sealing ring is fixedly mounted in the valve body and arranged close to the air chamber.

[0019] As a preferred embodiment of the present invention, the side wall of the side cabinet is provided with a movable groove for moving the connecting rod up and down.

[0020] As a preferred embodiment of the present invention, the float is provided with a horizontal groove for the connecting rod to pass through.

[0021] A limiting plate is also fixedly installed on the connecting rod. The limiting plate is movably disposed in the limiting groove, which is opened on the inner wall of the rod groove. A displacement spring is also provided between the limiting plate and the right inner wall of the limiting groove.

[0022] As a preferred embodiment of the present invention, a clearance groove is provided on one side of the float back guide rail, an arc-shaped head is provided at the end of the connecting rod, and an arc-shaped protrusion is fixedly installed in the middle of the inner side wall of the side cabinet.

[0023] As a preferred embodiment of the present invention, the connecting rod is further provided with a spline protruding thereon, the spline being slidably disposed within a groove, the groove being formed on the inner wall of the rod groove.

[0024] (III) Beneficial Effects

[0025] Compared with the prior art, the present invention provides a building construction operation platform, which has the following beneficial effects:

[0026] 1. The building construction platform has guide rails that are fixed to the building facade by suction cups. When the suspended platform moves up and down, the moving wheels installed on its U-shaped plate also move in the wheel grooves of the guide rails, which can guide and limit the up and down movement of the suspended platform. This not only improves the stability of the suspended platform's up and down movement, but also effectively prevents the suspended platform from swaying laterally in the air.

[0027] 2. When the moving wheel of this building construction platform moves to the end of the wheel groove, the guide rail can automatically release the suction cup from the building facade and move the guide rail along the direction of movement of the moving wheel, so that the moving wheel is once again located in the middle of the wheel groove, thereby achieving the effect of automatic track laying. This allows for long-distance vertical lifting and lowering of the suspended platform, and at the same time, it does not require an excessively long guide rail; only one guide rail is needed.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example:

[0039] Please see Figure 1 -

[0040] Figure 8 A building construction operation platform, including a suspended platform 1, such as Figure 1 As shown, a U-shaped plate 2 is fixedly installed on the side of the suspended platform 1. A movable wheel 3 is rotatably installed at the opening of the U-shaped plate 2. The movable wheel 3 is rolled in the wheel groove 5. The wheel groove 5 is opened on the guide rail 4. Suction cups 19 are evenly arranged on the side of the guide rail 4 facing away from the suspended platform 1. The suction cups 19 are used to adsorb and fix the guide rail 4 to the exterior of the building.

[0041] During construction, the guide rail 4 is attached to the building facade by suction cup 19. When the suspended platform 1 moves up and down, the moving wheels 3 installed on its U-shaped plate 2 also move in the wheel grooves 5 of the guide rail 4, which can guide and limit the up and down movement of the suspended platform 1, thereby improving the stability of the up and down movement of the suspended platform 1 and effectively preventing the suspended platform 1 from swaying laterally in the air.

[0042] In this invention, such as Figure 3 As shown, a mounting block 6 is fixedly installed on the side of the guide rail 4. The mounting block 6 is connected to the float 9, which is movably installed in the side cabinet 13, via a connecting rod 7. The side cabinet 13 is fixedly installed on the hanging basket 1. An upper spring 16 is provided between the float 9 and the inner top wall of the side cabinet 13, and a lower spring 17 is provided between the inner bottom wall.

[0043] In normal conditions, the float 9 is located in the middle of the side cabinet 13. After the guide rail 4 is fixed to the building facade by suction cup 19, if the basket 1 moves up, the float 9 will move down inside the side cabinet 13. At this time, the lower spring 17 is compressed. Conversely, if the basket 1 moves down, the float 9 will move up inside the side cabinet 13. At this time, the upper spring 16 is compressed. An active groove 18 is also provided on the side wall of the side cabinet 13 for the connecting rod 7 to move up and down, giving it sufficient space to move.

[0044] In this invention, an inflation mechanism is provided at both the upper and lower ends of the wheel groove 5. When the moving wheel 3 moves to the upper and lower ends of the wheel groove 5, the inflation mechanism can inflate the suction cup 19, thereby releasing the suction cup 19 from the building facade. As a result, the entire guide rail 4 is no longer fixed to the building facade. At this time, under the restoring force of the upper spring 16 or the lower spring 17, the float 9 will return to the middle position of the side cabinet 13, and the moving wheel 3 will also return to the middle of the wheel groove 5.

[0045] like Figure 4 -

[0046] Figure 8 As shown, the inflation mechanism specifically includes a slanted pressure block 20, a piston 21, a support spring 23, an inflation pipe 24, an air supply pipe 25, a branch pipe 26, and a one-way valve 27. Slanted pressure blocks 20 are movably and telescopically arranged on the inner walls at both the upper and lower ends of the wheel groove 5. In this embodiment, both the upper and lower slanted pressure blocks 20 have sloping surfaces, and the two sloping surfaces have opposite inclination directions, so that the moving wheel 3 can squeeze the slanted pressure block 20 whether it moves to the upper end or the lower end of the wheel groove 5.

[0047] The inclined pressure block 20 is fixedly installed on the piston 21. The piston 21 is movably arranged in the air chamber 22 opened in the guide rail 4, and a support spring 23 is fixedly arranged between the piston 21 and the inner wall of the air chamber 22. Both air chambers 22 are connected to the air supply pipe 25 embedded in the guide rail 4 through the inflation pipe 24. The air supply pipe 25 is connected to the suction cup 19 through the branch pipe 26. In this embodiment, a one-way valve 27 is provided on the inflation pipe 24 so that the gas in the air chamber 22 can be discharged in one direction. A one-way air inlet pipe is also provided on the inner wall of the air chamber 22.

[0048] In this way, when the inclined pressure block 20 is squeezed, it can fill the air in the air chamber 22 into the suction cup 19 through the air filling pipe 24, the air supply pipe 25 and the branch pipe 26 via the piston 21, thereby releasing the suction cup 19 from the adsorption and fixation on the building facade.

[0049] like Figure 8As shown, the one-way valve 27 specifically includes a valve body 2701, a frustum-shaped valve core 2702, a clamping spring 2703, a sealing ring 2704, and a conical groove 2705. The valve body 2701 is fixedly installed on the air inlet pipe 24. The frustum-shaped valve core 2702 is movably arranged in the valve body 2701. The frustum-shaped valve core 2702 is clamped by the clamping spring 2703 on the conical groove 2705 of the sealing ring 2704. The sealing ring 2704 is fixedly installed in the valve body 2701 and is arranged close to the air chamber 22.

[0050] In this way, the air in the air chamber 22 can push the frustum-shaped valve core 2702 to allow air to enter the air supply pipe 25, while the air in the air supply pipe 25 cannot flow in the reverse direction.

[0051] In short, after the guide rail 4 is attached to the building facade by suction cup 19, whenever the moving wheel 3 moves to the end of the wheel groove 5 and squeezes the inclined pressure block 20, it can inflate the suction cup 19, thereby releasing the suction cup 19 from the building facade.

[0052] Furthermore, after the suction cup 19 is released from its adhesion to the building facade, under the restoring force of the upper spring 16 or the lower spring 17, the float 9 will return to the middle position of the side cabinet 13, and the moving wheel 3 will also return to the middle of the wheel groove 5.

[0053] At this point, if the guide rail 4 is reattached and fixed to the building facade using suction cup 19, the "rail connection" can be completed. Then, by continuing to move the suspended platform 1...

[0054] Therefore, in this embodiment, as Figure 4 As shown, the float 9 has a horizontal groove 8 for the connecting rod 7 to pass through. The connecting rod 7 passes through the groove 8 and has a spline protruding on it. The spline is slidably disposed in the groove. The groove is located on the inner wall of the groove 8. Through the arrangement of the spline and the groove, the connecting rod 7 can be prevented from rotating in the groove 8, thereby keeping the guide rail 4 vertical.

[0055] A limiting plate 11 is also fixedly installed on the connecting rod 7. The limiting plate 11 is movably disposed in the limiting groove 12. The limiting groove 12 is opened on the inner wall of the rod groove 8. A displacement spring (not shown in the figure) is also provided between the limiting plate 11 and the right inner wall of the limiting groove 12.

[0056] In addition, a clearance groove 14 is provided on one side of the float 9 facing away from the guide rail 4, an arc head 10 is provided at the end of the connecting rod 7, and an arc protrusion 15 is fixedly installed in the middle of the inner side wall of the side cabinet 13.

[0057] When the float 9 is located in the middle of the side cabinet 13, the entire connecting rod 7 will be pushed to the right under the action of the arc head 10, at which time the displacement spring is compressed by the limiting plate 11.

[0058] Moving the connecting rod 7 to the right will cause the guide rail 4 to move to the right, making it easier to push the suction cup 19 on the guide rail 4 tightly onto the building facade, thereby adsorbing and fixing the guide rail 4.

[0059] After the guide rail 4 is fixed by suction cup 19, no matter whether the basket 1 moves up or down (the corresponding float 9 moves down or up in the side cabinet 13), the suction force of suction cup 19 will overcome the restoring force of the displacement spring, keeping the displacement spring in a compressed state.

[0060] Until air is introduced into the suction cup 19, the adhesion is released and the fixation is broken:

[0061] At this time, the float 9 is located at the end of the side cabinet 13. On the one hand, the float 9 will return to the middle position of the side cabinet 13 under the restoring force of the lower spring 17 or the upper spring 16. On the other hand, the displacement spring will support the limiting plate 11, so that the connecting rod 7 and the guide rail 4 move to the left. The purpose of the leftward movement of the connecting rod 7 and the guide rail 4 is to release the suction cup 19 from the building facade and to avoid friction between the suction cup 19 and the building facade during the movement of the guide rail 4.

[0062] After the float 9 returns to the middle position of the side cabinet 13, the arc-shaped protrusion 15 will push the connecting rod 7 to the right again, so that the guide rail 4 will be attached and fixed to the building facade again. At this time, the moving wheel 3 will also be in the middle position of the wheel groove 5 again, and so on.

[0063] Therefore, in this embodiment, when the moving wheel 3 moves to the end position of the wheel groove 5, the guide rail 4 can automatically release the suction cup 19 from the building facade and move the guide rail 4 along the movement direction of the moving wheel 3, so that the moving wheel 3 is located in the middle of the wheel groove 5 again, thereby achieving the effect of automatic track laying. This can realize the long-distance vertical lifting of the suspended basket 1 with only one guide rail 4, and no electrical control equipment (such as motors) is required.

[0064] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
