Description

Technical Field

[0001] This invention relates to the field of prefabricated building steel structure installation technology, and in particular to a simple temporary welding platform device for high-altitude applications. Background Technology

[0002] When performing outdoor work at heights, platforms need to be erected around the steel structure to allow construction workers to perform aerial welding and other construction activities, such as in multi-story steel structure buildings. The hoisting of these large steel components often requires extensive welding and assembly work in the air. Welding and high-strength bolt connections need to be performed on-site after the components are installed. However, the poor working conditions and insufficient operating space at height not only make it difficult to guarantee the quality of welding and tightening but also affect the accuracy of joint connections, thus compromising the overall quality of the project. Therefore, working platforms are erected in the air and dismantled after the high-altitude work is completed.

[0003] Known simple platforms for high-altitude operations are generally constructed by welding angle steel directly to the steel structure on the ground before hoisting large steel components, creating a cantilevered platform for use during hoisting. However, directly welding the cantilever to the steel structure makes disassembly cumbersome after use, and the fixed position of the simple platform is inconvenient for aerial operations requiring significant displacement. Existing welding platforms, due to their simple connection methods between the platform and the structure to be welded, suffer from poor connection strength. Furthermore, the relatively light weight of the welding platform makes it susceptible to swaying in the air due to environmental factors and the height at which it is lifted, resulting in an inadequate connection between the welding platform and the structure to be welded. Summary of the Invention

[0004] The present invention addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The present invention provides a simple temporary high-altitude welding platform device to solve the technical problem that the connection method between the existing welding platform and the structure to be welded is too simple, resulting in poor stability of the welding platform after connection.

[0005] The present invention adopts the following technical solution: a simple temporary high-altitude welding platform device, including an operating platform, an adjustable screw base for connecting the operating platform to the structure to be welded, a center of gravity adjustment mechanism for changing the center of gravity position of the operating platform, and a connection mechanism for facilitating stable and rapid installation between the operating platform and the structure to be welded. The operating platform is provided with a first lifting lug and a second lifting lug connected to a safety rope on both sides, and a safety baffle is provided at one end of the operating platform.

[0006] Furthermore, the connecting mechanism includes an angle steel frame, which is disposed beside the adjustable screw base. The angle steel frame has an L-shaped cross-section. A mating frame is rotatably connected to the top of the angle steel frame. An arc-shaped block is provided on the inner surface of the mating frame. Movable plates are provided inside the angle steel frame and the mating frame. The movable plates are slidably connected to the angle steel frame. Guide plates are provided on the outer sides of both ends of the angle steel frame. Guide grooves are opened in the guide plates. Connecting springs are provided in the guide grooves. One-way torsion spring limiting blocks are provided on the outer side of the movable plates. A telescopic guide shaft is provided on the mating frame. The telescopic guide shaft is inserted into the guide plate and is located at the end of the connecting spring.

[0007] Furthermore, the movable plate is connected to the mating frame by a guide rope, and a guide roller is provided on the inner surface of the painting frame, through which the guide rope passes.

[0008] Furthermore, the upper surface of the operating platform is provided with an arc-shaped groove for use with the arc-shaped block, the middle part of the operating platform is provided with a movable groove, and the bottom of the end of the operating platform is provided with a mounting groove.

[0009] Furthermore, the inner surfaces of both the mating frame and the angle steel frame are in contact with the outer surface of the operating platform.

[0010] Furthermore, the center of gravity adjustment mechanism includes a movable block and a torsion spring block. The movable block is located in a movable groove and has a hollow structure. A central rolling ball block is movably connected inside the movable block. The movable block is connected to the operating platform via a rotating block. The torsion spring block is located in a mounting groove opened on the lower surface of the end of the operating platform.

[0011] Furthermore, the rotating block is located at the center of the movable block.

[0012] Furthermore, the torsion spring block is initially in a vertical state.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] Firstly, this welding platform changes the installation method during use. Traditional welding platforms are hoisted with safety ropes and then placed on the structure to be welded for connection. This simple method results in poor connection stability. Therefore, this invention uses a plug-in connection, which makes the connection more stable. However, with plug-in connections, the thickness between the plug and the platform is often basically the same to ensure connection stability. This method makes it difficult to plug in, thus increasing the installation difficulty. This invention changes the plug structure of the connection mechanism so that the inlet size of the plug is much larger than the thickness of the platform in the initial stage, making it easy to insert during the plugging process. At the same time, the arc plate can also stabilize the inserted plate during the continuous plugging process. When the platform is installed, if it tilts, the arc plate can be used to position it. Only when the platform is removed from the plug interface will the arc plate be removed from the corresponding arc groove.

[0015] Secondly, by adding a movable center of gravity adjustment mechanism to the platform, the center of gravity position of the platform varies in different states. During hoisting, the center of gravity is in the central position, which increases the stability of the plates during hoisting and reduces swaying, facilitating insertion. When the platform is inserted into the connecting mechanism, the center of gravity shifts towards the connecting mechanism. Although the platform extends far beyond the connection point of the connecting mechanism, the center of gravity being at the connection point avoids the impact of the extended part on the connecting mechanism. Without the additional center of gravity adjustment mechanism, the center of gravity of the welding platform, which is relatively far from the angle steel frame, would exert an oblique load on the mating frame, generating additional force. However, by changing the center of gravity (since the center of gravity is now relatively close to the connecting mechanism, the tilting force of the welding platform is smaller), the oblique load generated by the welding platform after connection on the connecting mechanism can be reduced, increasing the service life of the connecting mechanism. In summary, the connection method between the platform and the connecting bracket remains unchanged, ensuring its ease of installation and portability. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] The following is combined with Figures 1 to 6 As shown, this embodiment of the invention provides a simple temporary high-altitude welding platform device, including an operating platform 4, an adjustable screw base 1 for connecting the operating platform 4 to the structure to be welded, a center of gravity adjustment mechanism 7 for changing the center of gravity position of the operating platform 4, and a connection mechanism 2 for facilitating stable and rapid installation between the operating platform 4 and the structure to be welded. The operating platform 4 is provided with a first lifting lug 3 and a second lifting lug 6 on both sides, which are connected to a safety rope. A safety baffle 5 is provided at one end of the operating platform 4.

[0031] Specifically, the connecting mechanism 2 includes an angle steel frame 22, which is located beside the adjustable screw base. The angle steel frame 22 has an L-shaped cross-section. A mating frame 24 is rotatably connected to the top of the angle steel frame 22. An arc-shaped block 29 is provided on the inner surface of the mating frame 24. A movable plate 21 is provided inside the angle steel frame 22 and the mating frame 24. The movable plate 21 is slidably connected to the angle steel frame 22. Guide plates 26 are provided on the outer sides of both ends of the angle steel frame 22. A guide groove is provided in the guide plate 26. A connecting spring 23 is provided in the guide groove. A one-way torsion spring limiting block 27 is provided on the outer side of the movable plate 21. A telescopic guide shaft 25 is provided on the mating frame 24. The telescopic guide shaft 25 is inserted into the guide plate 26 and is located at the end of the connecting spring 23.

[0032] Specifically, the movable plate 21 is connected to the mating frame 24 by a guide rope 28, and a guide roller is provided on the inner surface of the painting frame, through which the guide rope 28 passes.

[0033] Specifically, the upper surface of the operating platform 4 is provided with an arc-shaped groove 41 that cooperates with the arc-shaped block 29, the middle part of the operating platform 4 is provided with an movable groove 42, and the bottom of the end of the operating platform 4 is provided with an installation groove.

[0034] Specifically, the inner surfaces of both the mating frame 24 and the angle steel frame 22 are in contact with the outer surface of the operating platform 4.

[0035] During operation, when the operating platform 4 is hoisted and inserted into the angle steel frame 22 by the cooperation of the arc-shaped block 29 and the arc-shaped groove 41, the cooperating frame 24 will continuously shift, thereby forming a wrapping connection for the operating platform 4. At the same time, the arc-shaped block 29 will continuously insert into the arc-shaped groove 41, so that the initial insertion angle is a large opening shape, which facilitates the connection between the operating platform 4 and the angle steel frame 22. The cooperation of the arc-shaped block 29 and the arc-shaped groove 41 can play a role in connection restriction, so that the change of the center of gravity during later use will reduce the phenomenon of the operating platform 4 tilting upward.

[0036] Specifically, the center of gravity adjustment mechanism 7 includes a movable block 71 and a torsion spring block 74. The movable block 71 is located in the movable groove 42. The movable block 71 has a hollow structure. A central rolling ball block 73 is movably connected inside the movable block 71. The movable block 71 is connected to the operating platform 4 through a rotating block 72. The torsion spring block 74 is located in the mounting groove opened on the lower surface of the end of the operating platform 4.

[0037] Specifically, the rotating block 72 is located at the center of the movable block 71.

[0038] During operation, the rotating block 72 is located at the center of the movable block 71, and the movable block 71 is connected to the operating platform 4 via the rotating block 72. The movable block 71, rotating block 72, and operating platform 4 form a seesaw structure, allowing the tilt angle and position of the movable block 71 to continuously change. This alters the position of the internally mounted central rolling ball block 73, thereby changing the center position of the operating platform 4. The specific position of the rotating block 72 can be modified based on the weight of the internally mounted central rolling ball block 73. When the position of the rotating block 72 changes, the lever arm length also changes. By changing the lever arm length and the weight of the movable block 71, the tilt direction of the movable block 71 can change once it loses the resistance of the torsion spring block 74.

[0039] Specifically, the torsion spring block 74 is initially vertical.

[0040] During operation, in the initial state, the torsion spring block 74 is vertical, which lifts the end of the torsion spring block 74. The movable block 71 is tilted, and the end of the movable block 71 is located at the center of the operating platform 4. At this time, the central rolling ball block 73 is moved to the center of the operating platform 4, which strengthens the center of gravity of the operating platform 4. During the lifting process, it is subject to external factors, which causes it to sway.

[0041] Working principle: In use, first, the mating frame 24 is restored to its initial state, at which point the opening between the mating frame 24 and the angle steel frame 22 is at its maximum. Then, the adjustable screw base 1 is connected to the structure to be welded, and subsequently, safety ropes are connected to the first lifting lug 3 and the second lifting lug 6 respectively. Then, the operating platform 4 is lifted by a hoist. When the operating platform 4 is lifted to the appropriate height with the adjustable screw base 1, the operating platform 4 is moved and inserted between the angle steel frame 22 and the mating frame 24. During the insertion process, the large opening angle reduces the insertion difficulty. As the operating platform 4 is continuously inserted, it will abut against the movable plate 21, causing the movable plate 21 to move inward. During the movement of the movable plate 21, the guide rope 28 will drive the mating frame 24 to rotate. The deeper the insertion, the greater the rotation angle. During the continuous rotation, the arc-shaped block 29 will be inserted into the arc-shaped groove 41, and the telescopic guide shaft 25 will abut against the one-way torsion spring limiting block 27, causing it to rotate. Finally, the telescopic guide shaft 25 will move below the one-way torsion spring limiting block 27. At this point, the angle of the mating frame 24 can be adjusted by the one-way torsion spring limiting block 27. During the insertion process, the inner surface of the angle steel frame 22 will abut against the torsion spring block 74, causing the torsion spring block 74 to rotate. At this time, the movable block 71 loses the resisting force of the torsion spring block 74, causing the movable block 71 to tilt. When the movable block 71 tilts, the central rolling ball block 73 will change position accordingly. This means that when the operating platform 4 is inserted into the angle steel frame 22, the center of gravity will be biased towards the adjustable screw base 1. Although the operating platform 4 still extends far beyond the connection point of the angle steel frame 22, the center of gravity being located at the connection point reduces the impact of the gravity shift of the extended part on the angle steel frame 22. The operating platform 4 exerts a diagonal pulling force on the support when the platform and the support are connected by the connecting rope. However, the central rolling ball block 73 provides an additional downward gravity force on the support, which greatly counteracts the diagonal pulling force and prevents the support from tilting after installation due to the setting of the operating platform 4, thus increasing the safety of the platform. When dismantling is required, the telescopic guide shaft 25 is simply removed from the movable plate 21. As the operating platform 4 is continuously pulled out, the angle of the frame 24 can change, making dismantling easier.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
