Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, specifically to a suspended platform for steel beam installation. Background Technology

[0002] With the rapid development and technological progress of the construction industry, steel structure buildings are widely used due to their advantages such as high strength, light weight, and fast construction speed. In the construction process of steel structure buildings, the installation of steel beams is a key process. In order to ensure that the steel beams can be installed accurately and to protect the safety of construction workers, specially designed equipment to assist in the installation of steel beams is particularly important.

[0003] Traditional steel beam installation methods typically rely on cranes to lift the steel beams to a predetermined position, and then workers climb scaffolding or use simple suspension devices to reach the high-altitude work point to align and fix the steel beams. However, the high-altitude work environment is complex and changeable, and simple suspension devices cannot guarantee the safety of workers. If the lifting system of the suspended platform malfunctions (such as a broken steel cable or a power source failure), the suspended platform may suddenly drop, seriously threatening the lives of construction workers. Utility Model Content

[0004] To address the aforementioned problems, this utility model aims to provide a suspended platform for steel beam installation.

[0005] To achieve this technical objective, the solution of this utility model is as follows:

[0006] A suspended platform for installing steel beams includes a structural frame and an adaptive hook mounted on the steel beam. The structural frame is mounted on the adaptive hook. The platform also includes a safety column mounted on the steel beam. A safety rope is connected between the safety column and the structural frame. A speed limiter is fixedly installed on the safety column, and the safety rope passes around the speed limiter and is connected to the structural frame.

[0007] Preferably, the speed limiter includes a wheel seat fixedly mounted on the safety column, the inner wall of the wheel seat having equidistantly arranged positioning teeth, and a rotating wheel mounted on the wheel seat via bearings. Symmetrically arranged fly hammers are rotatably mounted at the axis of the rotating wheel. When the rotating wheel rotates too fast, the fly hammers hook the positioning teeth by centrifugal force.

[0008] Preferably, the mechanism also includes an elastic element connected to one side of the flying hammer, and a connecting rod rotatably mounted on the rotating wheel and parallel to the elastic element. The two ends of the connecting rod are rotatably connected to the flying hammers on both sides, forming a parallelogram mechanism.

[0009] Preferably, the surface of the reel has a groove that is adapted to the safety rope.

[0010] Preferably, the safety column includes a U-shaped plate and a column welded to the U-shaped plate, the U-shaped plate being fixed to the steel beam by bolts.

[0011] Preferably, the structural frame is equipped with indicator lights and alarms, the wheel has a built-in sensor, and the indicator lights and alarms are electrically connected to the sensor.

[0012] Preferably, the adaptive hook has a first reinforcing rod and a threaded second reinforcing rod, the first reinforcing rod and the second reinforcing rod being arranged parallel to each other.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. The steel beam installation scaffold designed in this application has an adaptive hook that is securely attached to the steel beam under normal working conditions, keeping the structural frame in a horizontal position. If the hook comes loose or other malfunctions cause the structural frame to begin to slide, the safety rope will be tightened, and the speed limiter will be triggered. After the speed limiter is activated, it will limit the descent speed of the structural frame, ensuring that it descends slowly and in a controlled manner to the ground or other safe height. The safety column and the speed limiter work together to ensure that even in the worst case, the safety of construction personnel can be protected to the maximum extent.

[0015] 2. Under normal operating conditions, the sensor continuously monitors the status of the rotor and sends the data to the control system. When the sensor detects an abnormality, such as the rotation speed exceeding the set threshold, the indicator light will light up immediately, the alarm will emit a high-decibel sound alarm, and a visual warning will be issued to the construction personnel.

Detailed Implementation

[0021] The utility model of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments. In order to provide a clear and complete description of the technical solution, the following embodiments are selected for illustration; other embodiments obtained based on the content described in this application without creative effort are all within the scope of protection of this utility model.

[0022] In the following embodiments, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", "top / bottom" and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the purpose of clearly describing this embodiment, rather than indicating or implying that the device or element referred to must have a specific orientation, and therefore should not be construed as a limitation of this application.

[0023] Example:

[0024] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0025] This application discloses a suspended platform for steel beam installation, including a structural frame 1, which is the main body of the platform and provides a stable working platform for construction workers, and adaptive hooks 2 installed on the steel beams. These hooks can adapt to steel beams of different sizes or shapes, ensuring stable mounting regardless of changes in site conditions. This simplifies the installation process and reduces the need for other supporting structures. The structural frame 1 is mounted on the adaptive hooks 2. Preferably, the adaptive hooks 2 have a first reinforcing rod 201 to enhance their overall rigidity and prevent deformation under high tensile forces, and a threaded second reinforcing rod 8 for easy loading and unloading of the structural frame 1. The first reinforcing rod 201 and the second reinforcing rod 8 are arranged parallel to each other, sharing the load and improving the overall structural integrity. In terms of stability and load-bearing capacity, the double-bar design can better maintain the stability of the adaptive hook 2 in the event of unexpected external forces (such as wind loads, vibrations, etc.), reducing the possibility of accidents. It also includes safety columns 3 installed on the steel beams. Safety columns 3 are connected to the structural frame 1 by safety ropes 4. Safety columns 3 serve as auxiliary support points to increase the stability of the entire system. They are usually installed vertically on the steel beams and connected to the structural frame 1 by safety ropes 4, forming a double protection mechanism. If the main hook malfunctions, safety columns 3 can act as a second line of defense. Among them, a speed limiter 5 is fixedly installed on the safety column 3 to limit the descent speed. The safety rope 4 passes around the speed limiter 5 and is connected to the structural frame 1 to avoid a free fall, thereby greatly reducing the risk of injury to construction workers.

[0026] In normal operation, the self-adaptive hook 2 is securely attached to the steel beam, keeping the structural frame 1 in a horizontal position. If the hook comes loose or other malfunctions cause the structural frame 1 to begin to slide, the safety rope 4 will be tightened, triggering the speed limiter 5. Once activated, the speed limiter 5 restricts the descent speed of the structural frame 1, ensuring that it descends slowly and in a controlled manner to the ground or other safe height. The safety post 3 and the speed limiter 5 work together to ensure that even in the worst-case scenario, the safety of construction personnel is protected to the maximum extent.

[0027] Preferably, the speed limiter 5 includes a wheel seat 501 fixedly mounted on the safety post 3. The inner wall of the wheel seat 501 has equidistantly arranged positioning teeth 502 and a rotating wheel 503 mounted on the wheel seat 501 by bearings to ensure that the rotating wheel 503 can rotate freely. A symmetrically arranged fly hammer 504 is rotatably mounted at the axis of the rotating wheel 503. When the rotating wheel 503 rotates too fast, the fly hammer 504 hooks the positioning teeth 502 by centrifugal force.

[0028] With the above-described structure, under normal operating conditions, the wheel 503 rotates at a low speed or remains stationary. At this time, the fly hammer 504 remains in a retracted state and will not interfere with the normal operation of the wheel 503. If, for some reason, such as the main hook coming loose or a power system failure, the structural frame 1 begins to descend rapidly, this will cause the rotational speed of the wheel 503 to increase sharply. As the rotational speed of the wheel 503 increases, the centrifugal force on the fly hammer 504 also increases accordingly until it reaches a critical point. At this point, the fly hammer 504 will automatically unfold and engage with the positioning teeth 502 on the wheel seat 501. The engagement of the positioning teeth 502 and the fly hammer 504 instantly locks the wheel 503, preventing it from continuing to rotate, thereby effectively curbing the uncontrolled descent of the structural frame 1 and protecting the safety of the construction personnel.

[0029] Furthermore, it also includes an elastic element connected to one side of the flying hammer 504, and a connecting rod 506 rotatably mounted on the rotating wheel 503 and parallel to the elastic element. The two ends of the connecting rod 506 are rotatably connected to the flying hammers 504 on both sides respectively, forming a parallelogram mechanism.

[0030] It should be noted that the elastic element is the elastic telescopic rod 505. Under normal circumstances, the elastic telescopic rod 505 maintains appropriate tension on the flying hammer 504 to ensure that the flying hammer 504 is in a retracted state. When the rotating wheel 503 accelerates, the centrifugal force overcomes the tension of the elastic telescopic rod 505, causing the flying hammer 504 to unfold outward.

[0031] With the above structure, under normal operating conditions, the wheel 503 rotates slowly, and the flying hammer 504 remains in a retracted state due to the tension of the elastic telescopic rod 505, which does not affect the normal operation of the wheel 503. When the structural frame 1 begins to accelerate downward, the wheel 503 rotates rapidly, and the centrifugal force gradually increases, eventually exceeding the tension of the elastic telescopic rod 505, causing the flying hammer 504 to unfold outward. After unfolding, the flying hammer 504 hooks onto the positioning tooth 502 in the wheel seat 501, immediately locking the wheel 503 and preventing it from continuing to rotate. At the same time, the linkage rod 506 ensures that the flying hammers 504 on both sides unfold synchronously, forming a stable locking state. The surface of the wheel 503 has a rope groove 507 that matches the safety rope 4, so that the safety rope 4 maintains the correct position throughout the process, ensuring the effectiveness of the speed limiter 5.

[0032] The safety post 3 includes a U-shaped plate 301 and a post 302 welded to the U-shaped plate 301. The U-shaped plate 301 is the basic component of the safety post 3. Its shape design allows it to fit closely to the top or side of the steel beam, providing a wide contact area to distribute the load. The U-shaped plate 301 is fixed to the steel beam by bolts.

[0033] First, determine the installation position on the steel beam, clean the surface to ensure good contact and adhesion, place the U-shaped plate 301 in the predetermined position, and initially fix it with bolts, but do not tighten them completely, so as to make necessary adjustments. Use a level or other measuring tools to ensure that the U-shaped plate 301 and the column 302 are perpendicular to the ground, and adjust the position of the bolts as needed. After confirming that the position is correct, tighten the bolts thoroughly to ensure that the safety column 3 is stably and reliably fixed on the steel beam.

[0034] Indicator light 6 and alarm 7 are installed on the structural frame 1. The rotating wheel 503 has a built-in sensor, and the indicator light 6 and alarm 7 are electrically connected to the sensor.

[0035] It should be noted that the sensor is one of the following: a mechanical switch, a Hall effect sensor, or a photoelectric sensor, used to detect whether the speed limiter 5 has been activated. When the speed limiter 5 starts to operate, the sensor will generate an electrical signal.

[0036] Under normal operating conditions, the sensor continuously monitors the status of the rotor 503 and sends the data to the control system. When the sensor detects an abnormality, such as the rotation speed exceeding the set threshold, the indicator light 6 will light up immediately, and the alarm 7 will emit a high-decibel sound alarm to issue a visual warning to the construction personnel.

[0037] The sensor is connected to the indicator light 6 and the alarm 7 via wires or a wireless communication module to achieve data transmission and control signal transmission. Modern technology allows the use of low-power Bluetooth, Wi-Fi or other wireless protocols, making the wiring simpler and facilitating later maintenance.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any minor modifications, equivalent substitutions and improvements made to the above embodiments based on the technical essence of the present utility model should be included within the protection scope of the present utility model.
