A steel structure construction platform fixed by electromagnetic adsorption and its usage method

Abstract

This invention discloses an electromagnetically adsorbed and fixed steel structure construction platform and its usage method, including a main supporting steel structure, an adsorption-type construction platform, and control components. When powered by a battery in the battery pack, the intelligent controller controls the first electromagnet to generate electromagnetic attraction to adsorb and fix multiple right-angle channel steel beams, thus facilitating the rapid installation of the platform and saving installation time. It also allows workers to easily perform construction work on the adsorption-type construction platform. When powered by the battery in the battery pack, the second electromagnet in the multiple electromagnetic anti-detachment mechanisms does not generate attraction. Through the extension of the spring, the inclined insertion post extends into the right-angle channel steel beam. When the upper surface of the inclined insertion post contacts the inner wall of the top of the right-angle channel steel beam, the multiple electromagnetic anti-detachment mechanisms can engage with the multiple right-angle channel steel beams, preventing the adsorption-type construction platform from falling off and avoiding worker injury.

Description

Technical Field

[0001] This invention relates to the field of steel structure construction platform technology, and in particular to a steel structure construction platform fixed by electromagnetic adsorption and its usage method. Background Technology

[0002] With the improvement of my country's comprehensive national strength and economic development, architectural forms are showing a diversified development trend. Steel is favored for its many advantages such as light weight, high strength, and convenient and reliable connection. Modern steel structures are developing towards taller, larger and more complex structures. There are more and more large-span and high-rise buildings with complex steel structures, and the construction of steel structures is also facing greater challenges. Steel structure construction platforms provide the necessary working space for the hoisting, positioning, connection and construction of steel structure components and ancillary facilities.

[0003] As disclosed in CN115045494A, an electromagnetic adsorption-fixed steel structure construction platform and its construction method include an electromagnetic adsorption device and a working platform. The working platform includes crossbeams, longitudinal beams, trusses, guardrails, and panels. The crossbeams and longitudinal beams are vertically welded to the bottom, the trusses are welded to the crossbeams on both sides, the panels are welded to the longitudinal beams, and the guardrails are welded to the longitudinal beams on the rear side of the panels. The electromagnetic adsorption device is located on the front side of the working platform. The working platform is bolted to the electromagnetic adsorption device as a whole through the crossbeams and trusses. The electromagnetic adsorption device adsorbs onto the installed steel structure panels by electromagnetic force. This invention eliminates the need to weld and remove temporary lifting lugs or brackets supporting the platform on the steel structure, causing no damage to the main steel structure. The construction is green and environmentally friendly, saving resources. The construction platform can be moved using lifting equipment after the power is disconnected, making the platform easy and quick to turn around.

[0004] However, there are still drawbacks: in the event of a sudden power outage, although the battery can provide power, the battery's power supply time is limited. If the power outage lasts longer than the battery's power supply time, workers walking on the steel structure construction platform may cause the platform to move, which could lead to the platform falling and compromising the workers' safety. Summary of the Invention

[0005] To address the shortcomings of the aforementioned background technology, this invention proposes an electromagnetically adsorbed and fixed steel structure construction platform and its usage method, which solves the problem that electromagnetically adsorbed and fixed steel structure construction platforms in the prior art are easily moved.

[0006] The technical solution of this invention is implemented as follows:

[0007] A steel structure construction platform fixed by electromagnetic adsorption, comprising:

[0008] The main supporting steel structure includes multiple steel structural columns and multiple right-angle channel steel beams, and is used to support the work and installation work.

[0009] An adsorption-type construction platform includes a construction platform, a first electromagnet, and multiple electromagnetic anti-detachment mechanisms. The first electromagnet is installed at the bottom of the construction platform, and the construction platform is fixed to multiple right-angle channel steel beams by adsorption through the first electromagnet. The bottom of the construction platform is provided with multiple electromagnetic anti-detachment mechanisms that cooperate with the right-angle channel steel beams to prevent the construction platform from falling off the multiple right-angle channel steel beams.

[0010] A control component for intelligent control of operation and for providing power.

[0011] Furthermore, the construction platform includes a support platform, a protective door, a locking assembly, and a guardrail. A guardrail for protective work is welded to one side of the upper surface of the support platform. A protective door is provided in the middle of the front side of the guardrail, and the protective door is movably connected to the guardrail through multiple hinges. The guardrail and the protective door are locked together by the locking assembly.

[0012] Furthermore, the locking assembly includes a through-hole square post, two through-hole blocks, and a pin. The through-hole square post is welded to the protective door, the two through-hole blocks are welded to the protective railing, and the pin passes through the two through-hole blocks and the through-hole square post respectively for locking.

[0013] Furthermore, the bottom of the support platform is provided with a mounting groove that matches the first electromagnet.

[0014] Furthermore, the electromagnetic anti-detachment mechanism includes a protective sleeve, a T-shaped insulating rod, a second electromagnet, a slanted post, an anti-detachment plate, and a spring. The protective sleeve is welded to the support platform. A second electromagnet is installed on the inner wall of one side of the protective sleeve. A T-shaped insulating rod is slidably connected inside one side of the protective sleeve, and the T-shaped insulating rod passes through the second electromagnet. An anti-detachment plate is fixedly connected to the other end of the T-shaped insulating rod, and the anti-detachment plate is located inside the protective sleeve. A spring is sleeved on the outer wall of the T-shaped insulating rod, and both ends of the spring are in contact with the anti-detachment plate and the second electromagnet, respectively. A slanted post is fixedly connected to the end face of the anti-detachment plate away from the T-shaped insulating rod. The other end of the slanted post extends towards the right-angle channel steel beam after penetrating the protective sleeve, and completes the snap-fit ​​operation with the top of the right-angle channel steel beam.

[0015] Furthermore, the control component includes an intelligent controller and a battery assembly. The intelligent controller is mounted on the upper surface of the battery assembly and is electrically connected to a plurality of second electromagnets and a first electromagnet for intelligent control operation.

[0016] Furthermore, the battery assembly includes a protective casing and a battery, and the intelligent controller is electrically connected to the battery.

[0017] A method of using a steel structure construction platform fixed by electromagnetic adsorption as described in any of the above claims includes the following steps;

[0018] Step 1: Weld multiple right-angle channel steel beams to designated positions on multiple steel structure columns, and install multiple steel structure columns carrying right-angle channel steel beams at designated positions in the building construction according to the electromagnetic anti-detachment mechanism on the adsorption construction platform.

[0019] Step 2: The adsorption construction platform is hoisted onto multiple right-angle channel steel beams. When the inclined pins of the multiple electromagnetic anti-detachment mechanisms at the bottom of the adsorption construction platform contact the upper surface of the right-angle channel steel beams, the battery is in a non-powered state. The inclined pins will push the anti-detachment iron plate and T-shaped insulating rod outward and compress the spring. When the inclined pins separate from the top of the right-angle channel steel beams, the springs will extend, allowing the inclined pins to extend into the interior of the right-angle channel steel beams. This allows the upper surface of the inclined pins to contact the inner wall of the top of the right-angle channel steel beams, completing the locking work and preventing the adsorption construction platform from falling off.

[0020] Step 3: Remove the pin of the locking assembly to open the protective door. After the worker enters the suction-type construction platform, close the protective door and insert the pin into the through-hole square column and the two through-hole blocks of the locking assembly to complete the locking work.

[0021] Step 4: By operating the buttons on the intelligent controller, the controller will control the first electromagnet and multiple second electromagnets to work. When the first electromagnet is working, it will be fixedly connected to multiple right-angle channel steel beams, allowing the adsorption construction platform to be attached to the beams, facilitating work for the workers. When the multiple second electromagnets are working, they will attract multiple anti-detachment plates and inclined posts outwards, causing the inclined posts to separate from the right-angle channel steel beams and compressing multiple springs. In the event of a sudden power outage, the battery will continue to supply power, allowing the first electromagnet and multiple second electromagnets to continue working. When the battery is depleted, the first electromagnet and multiple second electromagnets will stop working, and the multiple springs will extend, pushing the anti-detachment plates and inclined posts towards the right-angle channel steel beams. This causes the inclined posts to extend into the beams, and the engagement is completed when the upper surface of the inclined posts contacts the inner top wall of the beams.

[0022] The beneficial effects of this invention are:

[0023] 1. In this invention, when the battery in the battery assembly is powered, the intelligent controller controls the first electromagnet to work, so that the first electromagnet generates electromagnetic attraction, thereby making the first electromagnet adsorb and fix to multiple right-angle channel steel beams. This facilitates the rapid installation of the adsorption construction platform, saves installation time, and at the same time, makes it convenient for workers to carry out building construction on the adsorption construction platform.

[0024] 2. In this invention, when the battery in the battery assembly is supplying power, the second electromagnet in the multiple electromagnetic anti-detachment mechanisms will not generate attraction. As a result, through the extension of the spring, the anti-detachment iron plate and the inclined insert will move towards the right-angle channel steel beam, so that the inclined insert extends into the inside of the right-angle channel steel beam. When the upper surface of the inclined insert contacts the inner wall of the top of the right-angle channel steel beam, the multiple electromagnetic anti-detachment mechanisms can complete the locking work with the multiple right-angle channel steel beams, thereby preventing the adsorption construction platform from falling off and avoiding worker injury.

Detailed Implementation

[0035] 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.

[0036] like Figures 1-8 As shown in Example 1, an electromagnetically adsorbed and fixed steel structure construction platform includes a main supporting steel structure, an adsorption-type construction platform, and a control component. The main supporting steel structure includes multiple steel structure columns 8 and multiple right-angle channel steel beams 7, which are used for supporting and installing work. The adsorption-type construction platform is used to protect workers and facilitate construction work on the platform. The platform includes a construction platform, a first electromagnet 10, and multiple electromagnetic anti-detachment mechanisms. The first electromagnet 10 is installed at the bottom of the platform, and it adsorbs and fixes the platform to the multiple right-angle channel steel beams 7. Multiple electromagnetic anti-detachment mechanisms are installed at the bottom of the platform near the first electromagnet 10, which cooperate with the right-angle channel steel beams 7 to prevent the platform from detaching from them. The control component is used for intelligent control and provides power.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, the construction platform includes a support platform 3, a protective door 5, a locking assembly 6, and a protective railing 9. A protective railing 9 for protective work is welded to one side of the upper surface of the support platform 3. A protective door 5 is located in the middle of the front side of the protective railing 9, and the protective door 5 is movably connected to the protective railing 9 through multiple hinges 4. The protective railing 9 and the protective door 5 are locked by the locking assembly 6. The locking assembly 6 includes a through-hole square post, two through-hole blocks, and a pin. The through-hole square post is welded to the protective door 5, and the two through-hole blocks are welded to the protective railing 9. The pin passes through the two through-hole blocks and the through-hole square post respectively to complete the locking work. The bottom of the support platform 3 has an installation groove that matches the first electromagnet 10. Through the construction platform, the protective work can be better carried out, making it convenient for workers to carry out construction.

[0038] like Figure 4, Figure 5 , Figure 6 and Figure 7 As shown, the electromagnetic anti-detachment mechanism includes a protective sleeve 11, a T-shaped insulating rod 12, a second electromagnet 13, an inclined insert 14, an anti-detachment iron plate 15, and a spring 16. The protective sleeve 11 is welded to the support platform 3. The second electromagnet 13 is installed on the inner wall of one side of the protective sleeve 11. The T-shaped insulating rod 12 passes through the inner wall of the protective sleeve 11. After the T-shaped insulating rod 12 is rotated 90 degrees, the long rod part in the middle passes through the protective sleeve 11, and the short rod part at the end is located outside the protective sleeve 11. The T-shaped insulating rod 12 can slide laterally on the protective sleeve 11, and the T-shaped insulating rod 12 passes through the second electromagnet 13. The other end of the T-shaped insulating rod 12 is fixedly connected to an anti-detachment plate 15, which is located inside the protective sleeve 11. A spring 16 is sleeved on the outer wall of the portion of the T-shaped insulating rod 12 inside the protective sleeve 11, with both ends of the spring 16 contacting the anti-detachment plate 15 and the second electromagnet 13, respectively. A slanted insert 14 is fixedly connected to the end face of the anti-detachment plate 15 away from the T-shaped insulating rod 12, and the other end of the slanted insert 14 extends through the other end of the protective sleeve 11 towards the right-angle channel steel beam 7, where it engages with the top of the right-angle channel steel beam 7. Figure 5 As shown. The electromagnetic anti-detachment mechanism can not only perform limit work, but also prevent detachment.

[0039] For intelligent control and power supply, the control component includes an intelligent controller 1 and a battery assembly 2. The intelligent controller 1 is mounted on the upper surface of the battery assembly 2, and is electrically connected to multiple second electromagnets 13 and a first electromagnet 10. Figure 8 As shown, the intelligent controller 1, the first electromagnet 10, and multiple second electromagnets 13 cooperate to complete the intelligent control work. The battery assembly 2 includes a protective shell and a battery. The intelligent controller 1 is electrically connected to the battery. Through the control assembly, the intelligent control work is realized, and the power supply work can also be performed.

[0040] Example 2: A method for using a steel structure construction platform fixed by electromagnetic adsorption, comprising the following steps:

[0041] Step 1: Weld multiple right-angle channel steel beams 7 to designated positions of multiple steel structure columns 8, and install multiple steel structure columns 8 carrying right-angle channel steel beams 7 at designated positions in the building construction according to the electromagnetic anti-detachment mechanism on the adsorption construction platform.

[0042] Step 2: Using a crane or forklift, the adsorption-type construction platform is delivered to the multiple right-angle channel steel beams 7. When the inclined pins 14 in the multiple electromagnetic anti-detachment mechanisms at the bottom of the adsorption-type construction platform contact the upper surface of the right-angle channel steel beams 7 (when the battery is not powered), the inclined pins 14 will push the anti-detachment iron plate 15 and the T-shaped insulating rod 12 outward and squeeze the spring 16. When the inclined pins 14 separate from the top of the right-angle channel steel beams 7, the spring 16 will extend, allowing the inclined pins 14 to extend into the interior of the right-angle channel steel beams 7, thereby making the upper surface of the inclined pins 14 contact the top inner wall of the right-angle channel steel beams 7, completing the locking work and preventing the adsorption-type construction platform from falling off.

[0043] Step 3: The worker leans the ladder against the surface of the support platform 3 near the protective door 5, then climbs the ladder and removes the pin of the locking component 6 to open the protective door 5. After opening the protective door 5, the worker can enter the adsorption construction platform. Once all the workers are inside the adsorption construction platform (leaving one worker to supervise on site), the worker closes the protective door 5 and inserts the pin into the through-hole square column and two through-hole blocks of the locking component 6 to complete the locking operation.

[0044] Step 4: Connect the battery in battery pack 2 to the external power switch (with the circuit breaker in the off state) via electrical wires. Then, the worker not on the suction-type construction platform turns on the external power switch, connecting the battery in battery pack 2 to the power supply. The battery will then begin storing power. After power is connected, the worker presses the power switch on the intelligent controller 1, activating the battery in battery pack 2. The worker then operates the buttons on the intelligent controller 1, which controls the first electromagnet 10 and multiple second electromagnets 13. When the first electromagnet 10 is active, it adheres to and is fixedly connected to multiple right-angle channel steel beams 7, allowing the suction-type construction platform to be attached to them, facilitating construction work on the platform. When the multiple second electromagnets 13 are active… Multiple second electromagnets 13 will attract multiple anti-detachment iron plates 15 and multiple inclined posts 14 outwards, causing the multiple inclined posts 14 to separate from the multiple right-angle channel steel beams 7, and compressing multiple springs 16. In the event of a sudden power outage, the battery will continue to supply power, allowing the first electromagnet 10 and multiple second electromagnets 13 to continue working. When the battery power is depleted, the first electromagnet 10 and multiple second electromagnets 13 will stop working. At this time, the multiple springs 16 will extend and push the multiple anti-detachment iron plates 15 and multiple inclined posts 14 towards the multiple right-angle channel steel beams 7, causing the multiple inclined posts 14 to extend into the multiple right-angle channel steel beams 7. When the upper surface of the multiple inclined posts 14 contacts the inner wall of the top of the multiple right-angle channel steel beams 7, the locking work is completed, preventing the adsorption construction platform from falling off and avoiding worker injury.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
