Description

Technical Field

[0001] The present invention relates to the technical field of engineering machinery, and more specifically to an assembled mobile working platform with an intelligent early warning function. Background Art

[0002] With the rapid development of urban rail transit, subway construction plays a positive role in alleviating urban traffic congestion and protecting the environment. The construction platform is an indispensable part of the construction process, which provides workers with a safe and stable working environment while improving construction efficiency and quality.

[0003] Subway construction work platforms usually need to adapt to complex geological conditions and different construction environments, such as holes and pits. Construction work above these scenes is a special and complex engineering challenge, requiring the work platform to be easy to install and disassemble, have a flexible and stable working surface, and allow efficient work in a limited space. However, the existing technology basically sets up a full-height scaffolding at the bottom of holes and pits, which has problems such as the inability to carry out construction in the construction area, difficulty in transporting materials, and high safety risks. There is little research and application of the existing technology on complex scenes such as holes and pits. Therefore, it is necessary to optimize the existing construction work platform to adapt to such complex construction environments and improve construction efficiency.

[0004] The Chinese patent application number 201520096469.X discloses an anti-electric and anti-falling platform, wherein the fixed platform is arranged on the top of the lifting device, the mobile platform is slidably arranged on the fixed platform, and the mobile platform is connected to the motor arranged in the fixed platform by transmission, the bottom of the fixed platform is provided with a height sensor, a pressure sensor and a current detector, the fixed platform and the mobile platform are both provided with guardrails along the periphery, the upper surfaces of the fixed platform and the mobile platform are both provided with insulating plates, the insulating plates are provided with anti-slip patterns, an alarm is provided on the upper part of the protective soundproof screen on the right side of the fixed platform, a control device is provided on the upper part of the guardrail on the left side of the mobile platform, and the height sensor, pressure sensor, current detector, alarm and motor are all electrically connected to the control device. The shortcomings of this patent: Although the working platform can monitor, analyze and warn the potential risks in the construction process in real time, and can provide an alarm in time when irregular safety behaviors occur, the platform fails to provide further safety protection when safety accidents such as falling from heights occur.

[0005] At the same time, the closed environment of subway construction is prone to noise pollution, which poses a serious threat to the health and safety of workers. Long-term exposure to high-decibel noise environment may cause workers to have increased psychological pressure, anxiety, irritability and other psychological problems. Noise interference may also cause workers to be distracted, reduce work efficiency and increase the risk of accidents.

[0020] Compared with the prior art, this patent has the following advantages:

[0021] 1. In the present invention, by setting up an intelligent video analysis system, the irregular behaviors of workers on the work platform can be monitored in real time. The camera collects video and photo data on the work platform in real time, and sends the video and photo data to the analysis module through the video stream module. After the analysis module determines that the worker's behavior is not in compliance with regulations, the sound and light alarm quickly emits a buzzer and flashes, reminding the workers to standardize safety behaviors and ensure safe construction, which is helpful for construction site safety management and reduces management costs.

[0022] 2. The present invention provides an anti-fall component to further protect the safety of workers. When a worker falls outside the protective soundproof screen area of ​​the working platform, the analysis module determines that the worker's body is in a dangerous area, the reaction module prompts the electric push rod to move downward, the limit rod is separated from the separation plate, and the anti-fall grid, foam plastic and separation plate on both sides are quickly popped out by the displacement spring to prevent the worker from continuing to fall. The micro-curved foam plastic is deformed under the action of the worker's gravitational potential energy to reduce falling injuries and protect the worker's life safety.

[0023] 3. The present invention is provided with a protective soundproof screen and foam plastic with good sound insulation performance. When the anti-fall component is not deployed, the protective soundproof screens around the working platform and the foam plastic at the bottom work together to cut off the noise propagation path, provide a quiet working space for the working platform, alleviate noise pollution at the construction site, and ensure the health and safety of workers.

[0024] 4. The present invention sets a damping component and an anti-falling component to work together to reduce the vibration of the working platform. When the working platform brakes or starts, the impact force of the working platform will act on the damping spring. After being impacted, the damping spring will be compressed and stretched to reduce the vibration of the working platform, and the hydraulic rod can limit the damping spring from rebounding too quickly. At the same time, the anti-falling component will move in the opposite direction of the working platform under the action of inertia, and then this part of kinetic energy will be consumed by the damping component, which can effectively reduce the impact force brought by the working platform. The damping component and the anti-falling component work together to avoid the situation where workers are prone to falling due to inertia during the start and stop of the working platform.

[0025] 5. The present invention provides a sufficient working surface above complex environments with limited spaces such as holes and pits by setting up motors and rollers to control the working platform to move back and forth on the steel track. It can move between different positions according to construction needs to adapt to different operation requirements, thereby improving construction efficiency and flexibility.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1

[0037] The work platform is assembled on the corridor outside the hole and moved along the two sides of the hole to the top of the hole. When dismantling, the work platform is moved to the corridor between the holes to complete the dismantling. The work platform is driven by two synchronous motors 14, and the main beam 5 and the track beam 4 form a frame. The steel plate units are assembled into the platform panel. Figure 1-Figure 3 As shown, an assembled mobile work platform with intelligent early warning function includes two parallel steel rails 1. The lower part of the steel rails 1 is fixedly connected to the structural floor 2 by chemical bolts and clamps. The upper part of the steel rails 1 is movably connected to the track beam 4 through rollers 3. The rollers 3 are arranged on both sides of the track beam 4. Two parallel main beams 5 are arranged above the track beam 4. The main beam 5 and the secondary beam 6 are fixedly connected by high-strength bolts. A steel plate 8 is arranged above the secondary beam 6, and a protective sound insulation screen 9 is arranged above the steel plate 8.

[0038] Specifically, the main beam 5 is assembled by main beam units connected by bolts; the steel plate 8 is assembled by steel plate units; and the protective sound insulation screen 9 is assembled by protective sound insulation screen units. The present invention adopts an assembled design, and the main beam 5, the steel plate 8 and the protective sound insulation screen 9 are all assembled by component units. The components are connected by high-strength bolts, which are easy to assemble and disassemble, have strong versatility, can meet different construction sites and on-site conditions, are simple and convenient to operate, and have high safety.

[0039] Specifically, the track beam 4 and the main beam 5 are steel box beams, and the secondary beam 6 is a channel steel beam. Before installation, the cross-sectional dimensions and connection strength designs of each component must be verified and qualified before construction can begin.

[0040] More specifically, two motors 14 are provided, which are respectively installed at one side end of two rail beams 4. The motor 14 drives the working platform to move at a speed of 10m / min. The power of the motor 14 is 0.8KW, and it has a built-in braking function. The present invention controls the working platform to move back and forth on the steel track 1 by setting the motor 14 and the roller 3, provides a sufficient working surface above the complex environment of limited space such as holes and pits, moves between different positions according to construction needs, adapts to different operation needs, and improves construction efficiency and flexibility.

[0041] Example 2

[0042] As described in the above embodiment 1, the structure controls the working platform to move back and forth on the steel track 1 by setting the motor 14 and the roller 3, providing a sufficient and flexible working surface for complex environments such as holes and pits in subway construction, but the platform fails to monitor, analyze and warn potential dangers in construction in real time, and fails to provide further safety protection when workers fall from heights. At the same time, due to the closed environment of subway construction, noise pollution is easily generated, which poses a serious threat to the health and safety of workers, and the following solutions are proposed to address the above problems.

[0043] Specifically, the column 10 is fixedly connected to the rail beam 4, and a camera 11 and an audible and visual alarm 12 are arranged on the column 10. Two cameras 11 are arranged on each of the column 10, the camera 11 and the audible and visual alarm 12, and the two cameras 11 collect video and photo data on the working platform in real time. The camera 11 is externally connected to an intelligent video analysis system 13; as shown in the attached Figure 8 As shown, the intelligent video analysis system 13 includes a device management module 131 , a video stream module 132 , an analysis module 133 , an early warning module 134 and a reaction module 135 .

[0044] More specifically, the equipment management module 131 is used to manage the video and photo data collected by the camera 11, and then the video stream module 132 is used to send the video and photo data to the analysis module 133. The analysis module 133 begins to identify the irregular behavior of the workers. When the workers do not wear safety helmets and safety belts, the early warning module 134 is used to obtain the command of the analysis module 133 to make the sound and light alarm 12 emit warning information such as beeps and flashes, reminding the workers to standardize safety behaviors and ensure safe construction, which is helpful for the safety management of the construction site and reduces management costs; when the worker falls outside the protective sound insulation screen 9 of the working platform, the analysis module 133 determines that the worker's body is in a dangerous area, and the reaction module 135 is used to obtain the command of the analysis module 133 to make the electric push rod 763 apply vertical pressure, and the limit rod 761 is separated from the separation plate 73. The anti-falling grid 72, foam plastic 77 and separation plate 73 on both sides are quickly ejected under the action of the displacement spring 74 to prevent the workers from continuing to fall. The slightly curved foam plastic 77 is deformed under the action of the gravitational potential energy of the workers to slow down the fall injury and protect the workers' lives.

[0045] Furthermore, the anti-falling assembly 7 is arranged below the working platform, as shown in the attached Figure 4-6 The anti-falling component 7 includes a slide groove 71, an anti-falling grid frame 72, a separation plate 73, a displacement spring 74, a vertical plate 75, an anti-falling lock 76 and a foam plastic 77. The anti-falling grid frame 72 is arranged above the slide groove 71, and a curved foam plastic 77 is arranged above the anti-falling grid frame 72. The foam plastic 77 can completely cover the anti-falling grid frame 72. The anti-falling grid frame 72 is fixedly connected to the separation plate 73. Both ends of the separation plate 73 are fixedly connected to one side of two groups of displacement springs 74. The other side of the two groups of displacement springs 74 is fixedly connected to the vertical plate 75. Two anti-falling locks 76 are arranged above the separation plate 73.

[0046] Specifically, as attached Figure 7 As shown, the anti-fall lock 76 includes a limit rod 761, a rotating shaft 762, an electric push rod 763 and a support rod 764. The limit rod 761 is in contact with the separation plate 73 and the electric push rod 763, and the support rod 764 is fixedly connected to the vertical plate 75. The limit rod 761 rotates around the rotating shaft 762 under the vertical pressure of the electric push rod 763 to separate from the separation plate 73.

[0047] More specifically, the anti-falling components 7 are arranged symmetrically, and the anti-falling grid 72, foam plastic 77 and separation plate 73 are controlled to move by telescopic displacement springs 74. The mesh holes of the anti-falling grid 72 are all square holes, and the spacing between steel bars is 200 mm.

[0048] It should be noted that when a worker falls outside the protective soundproof screen 9 of the work platform, the reaction module 135 prompts the electric push rod 763 to apply a vertical downward pressure, which is sufficient to rotate the limit rod 761 around the rotating shaft 762. At this time, the separation plate 73 is not constrained by the limit rod 761, and the displacement spring 74 shrinks rapidly. The anti-falling grid frame 72, foam plastic 77 and separation plate 73 on both sides quickly pop out and stick to the vertical plate 75 to prevent the worker from falling continuously to the bottom of the hole. After the use of the anti-falling grid frame 72 and foam plastic 77 is finished, the anti-falling grid frame 72 is pushed by manpower to move close to the limit rod 761. When the anti-falling grid frame 72 contacts the limit rod 761, the limit rod 761 rotates around the rotating shaft 762, and the anti-falling grid frame 72 continues to move beyond the limit rod 761. At this time, the limit rod 761 rotates in the opposite direction under the action of gravity to fix the anti-falling grid frame 72 and get stuck in the slide groove 71. The anti-fall lock 76 has a simple design structure and can ensure the stable operation of the anti-fall grid frame 72.

[0049] This invention can not only monitor, analyze and warn of potential risks in the construction process in real time, but also when a fall accident occurs, the intelligent video analysis system 13 can accurately control the anti-fall lock 76 to prompt the anti-fall grid 72 and foam plastic 77 to pop out quickly, and the work platform can provide further safety protection.

[0050] Furthermore, as attached Figure 4 As shown, a curved foam plastic 77 is arranged above the anti-falling grid 72. The foam plastic 77 has good sound insulation performance and can block the noise from the bottom of the working platform to the working platform when the anti-falling component 7 is not deployed. The protective sound insulation screen 9 around the working platform and the foam plastic 77 at the bottom work together to cut off the noise propagation path, provide a quiet working space for the working platform, alleviate noise pollution at the construction site, and ensure the health and safety of workers.

[0051] Example 3

[0052] Based on the above-mentioned embodiments 1 and 2, the structure solves the problem of insufficient working surface above holes and pits and inconvenient construction during subway construction, and sets up an intelligent video analysis system 13 and an anti-falling component 7 to ensure the safety of workers. The protective soundproof screen 9 and foam plastic 77 are set to reduce noise pollution, but no measures are taken to solve the problem that workers are prone to fall due to inertia when the working platform brakes or starts. The following technical solutions are proposed to solve the above technical problems.

[0053] Specifically, as attached Figure 4As shown, a damping assembly 15 is arranged between the working platform and the anti-falling assembly 7, and the damping assemblies 15 are arranged at equal intervals and staggered on both sides of the middle vertical plate 75 of the anti-falling assembly 7, and two groups of damping assemblies 15 are arranged on each side. The damping assembly 15 includes a connecting rod 151, a hydraulic rod 152 and a damping spring 153. The upper part of the connecting rod 151 is movably hinged to the secondary beam 6, and the lower part of the connecting rod 151 is fixedly connected to the anti-falling assembly 7. The two sides of the hydraulic rod 152 are fixedly connected to the connecting rod 151 and the main beam 5, and the two sides of the damping spring 153 are fixedly connected to the connecting rod 151 and the main beam 5.

[0054] When the working platform brakes or starts, the impact force of the working platform will act on the damping spring 153. After the damping spring 153 is impacted, it will be compressed and stretched to reduce the vibration of the working platform. It should be noted that after the damping spring 153 is deformed by the impact, it will bounce repeatedly, and the hydraulic rod 152 can limit the damping spring 153 from rebounding too quickly, so that the vibration of the damping spring 153 can decay faster. At the same time, the anti-falling component 7 will move in the opposite direction of the working platform under the action of inertia, and then consume this part of the kinetic energy through the damping component 15, which can effectively reduce the impact force brought by the working platform. The damping component 15 and the anti-fall component 7 work together to prevent workers from falling due to inertia during the start-up and stop of the work platform. Even if the worker falls onto the anti-fall grid 72 due to inertia, the fallen person first contacts the foam plastic 77 and then contacts the anti-fall grid 72. The foam plastic 77 can be used to cushion and reduce shock to the falling person, reducing the contact force between the worker and the anti-fall grid 72, thereby further improving the safety of the workers during construction.

[0055] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
