Description

Technical Field

[0001] This application generally relates to the field of outdoor high-altitude construction suspension equipment technology, and more specifically, to a collision avoidance safety device for high-altitude suspended baskets and high-altitude operation equipment. Background Technology

[0002] Suspended platforms are widely used in building construction, existing building maintenance, infrastructure construction, new energy projects, and related fields. As a vertical transportation and work platform, suspended platforms are used in construction installation, material transportation, cleaning and maintenance, inspection and repair, etc., which can effectively improve work efficiency and reduce safety risks.

[0003] A suspended platform is a type of aerial work platform that is fixed to a building or structure via wire ropes, supports, trolleys, and other suspension devices to support construction workers, tools, and materials. It primarily relies on the suspension system for lifting, lowering, and positioning; however, in the event of sudden extreme weather, especially strong winds, it is prone to dangerous situations such as high-altitude collisions, equipment failure, or even falls.

[0004] Currently, suspended platforms generally improve their protective performance by adding anti-collision wheels and covering them with cushioning materials. However, in extreme wind conditions, these measures only provide cushioning after the platform collides with the building. After the collision, the platform remains suspended by steel cables and will continue to bounce and swing a second time due to the wind, potentially leading to uncontrollable continuous collisions, which can easily cause personal injury and damage to buildings and equipment.

[0010] According to one embodiment of this application, the cross-sectional dimension of the adsorption pore is larger than the cross-sectional dimension of the flow pore.

[0011] According to one embodiment of this application, the buffer mechanism includes: A fixing rod is disposed within the accommodating cavity and fixedly connected to the housing, wherein the axial direction of the fixing rod is perpendicular to the moving direction of the adsorption element; The transmission component includes a connecting rod, an elastic element, and a sleeve.

The first end of the connecting rod is hinged to the sleeve, and the second end of the connecting rod is movably connected to the connecting member. The detection element is disposed on the sleeve.

[0012] According to one embodiment of this application, two transmission components are provided at intervals along the axial direction of the fixed rod, and the two elastic elements are respectively provided on the sides of the two sleeves that are far apart from each other.

[0013] According to one embodiment of this application, the buffer mechanism further includes a mounting component, and the connecting rod is movably connected to the connecting member via the mounting component. The mounting component includes: A first mounting component is hinged to the second end of the connecting rod; and The second mounting component is disposed on the connector and is connected to the first mounting component via a locking accessory; The connector has a groove that extends along the axial direction of the fixing rod, and the second mounting member is slidably disposed within the groove.

[0014] According to another aspect of this application, a high-altitude work equipment is provided, including a suspended platform and a collision avoidance safety device for the suspended platform, wherein the suspended platform includes: A work platform, wherein the anti-collision safety device is disposed at the bottom of the work platform; and A suspension drive device is used to drive the lifting and lowering of the work platform.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Reference Figures 1-4 This embodiment provides a collision avoidance safety device for a suspended platform. The collision avoidance safety device for a suspended platform includes a housing 1, an adsorption mechanism 2, and a control mechanism 3. The housing 1 has a receiving cavity 11 and a wall-facing surface 12 facing the building wall. The adsorption mechanism 2 is disposed in the receiving cavity 11 and includes a vacuum tank 21 and an adsorption element 22. The adsorption surface 221 of the adsorption element 22 protrudes from the wall-facing surface 12 and has multiple adsorption holes 23. The vacuum tank 21 is connected to each adsorption hole 23 through a pipeline to provide negative pressure to each adsorption hole 23. The control mechanism 3 includes a controller, an on / off element, and a detection element. The on / off element and the detection element are electrically connected to the controller. The on / off element is used to control the on / off of the pipeline, and the detection element is used to detect whether the adsorption surface 221 impacts the building wall.

[0034] The relative position of the adsorption component 22 to the building wall is monitored in real time by a detection device. In extreme wind conditions, the wind will cause the suspended platform and the anti-collision safety device connected to it to swing. When the detection device detects that the anti-collision safety device has collided with the building wall during the swing, a signal is transmitted to the controller. The controller controls the on / off device to connect the pipeline, and the vacuum tank 21 is connected to the adsorption hole 23. This reduces the pressure inside the adsorption hole 23, generating a negative pressure adsorption force to stably adsorb the adsorption surface 221 of the adsorption component 22 to the building wall, thereby ensuring the stability of the suspended platform. In extreme weather conditions, this provides passive defense after the suspended platform collides with the building, effectively avoiding continuous collisions between the suspended platform and the building wall. It provides workers with sufficient emergency protection time, improves the safety of personnel inside the suspended platform, reduces collision losses, and lowers operational risks.

[0035] The shell 1 serves as a protective and support structure. The shell 1 can be rectangular, cubic, or cylindrical, etc. It can be adapted to the actual working needs of the aerial work platform, the working environment, and the anti-collision safety device. This embodiment will not elaborate on this aspect.

[0036] Reference Figure 1 , Figure 3 and Figure 4In some embodiments, the adsorption mechanism 2 includes a vacuum tank 21 and an adsorption element 22. The vacuum tank 21 is set in the accommodating cavity 11 of the housing 1 by the mounting bracket 5, thereby ensuring the stability and reliability of the position of the vacuum tank 21 and ensuring that the vacuum tank 21 can stably communicate with the adsorption hole 23 under extreme working environment, and ensuring the reliable negative pressure adsorption effect of the adsorption element 22.

[0037] Combination Figure 7 The mounting bracket 5 includes two spaced-apart L-shaped structural beams 51 symmetrically arranged on the housing 1. A support frame 52 is mounted on each L-shaped structural beam 51. The support frame 52 has a mounting base 521 and a mounting adapter surface 522 located above the mounting base 521. The two ends of the mounting base 521 and the mounting adapter surface 522 are connected by a vertical plate 523. To ensure the structural strength of the support frame 52, the mounting base 521, the mounting adapter surface 522, and the vertical plate 523 are integrally formed. Of course, in some embodiments, the mounting base 521, the mounting adapter surface 522, and the vertical plate 523 can also be connected by methods such as welding or bonding.

[0038] A through hole 524 is formed between the mounting base 521, the mounting adapter surface 522, and the upright plate 523. The mounting base 521 is used to connect with the L-shaped structural beam 51, and the mounting adapter surface 522 is used to support and fix the vacuum tank 21. The mounting base 521 contacts and engages with the L-shaped structural beam 51, and is connected by bolts or locating pins. The through hole 524 facilitates the installation and removal of bolts or locating pins. The overall structure of the mounting adapter surface 522 can be adapted to the outer contour of the vacuum tank 21, thereby ensuring effective support and fixation of the vacuum tank 21.

[0039] Reference Figure 3 Optionally, two or more vacuum tanks 21 can be provided. Each vacuum tank 21 is connected to the adsorption hole 23 through a connecting pipe. Each pipe is equipped with a switch for regulating the opening and closing of the pipe, and each switch is electrically connected to the controller. When the adsorption element 22 impacts the building wall, the controller controls the opening of any one of the switches, connecting the adsorption hole 23 to the corresponding vacuum tank 21, thereby establishing a negative pressure environment to adsorb the adsorption surface 221 onto the building wall.

[0040] After adsorption is complete, the detection device can also detect the state of the adsorption element 22. If the adsorption element 22 is detected to have a downward movement trend or to move relative to the building wall, the controller can also control the opening of another switch to connect the adsorption element 22 to the corresponding vacuum tank 21, thereby enhancing the negative pressure adsorption force in the adsorption hole 23, effectively ensuring the stability and reliability of the adsorption element 22 adsorbed on the building wall, and avoiding the situation of falling off.

[0041] Furthermore, since there are safety hazards when the same connected vacuum tank 21 and pipeline are reused, a safety inspection and recalibration must be performed after each use before it can be used again.

[0042] Reference Figure 1 In some embodiments, the adsorption surface 221 of the adsorption member 22 protrudes from the housing 1 to ensure that when the anti-collision safety device collides with the building wall, the adsorption surface 221 of the adsorption member 22 can first contact and collide with the building wall, ensuring the detection effect of the detection member, ensuring the overall reaction time of the device when the collision occurs, and improving the safety of the device.

[0043] Reference Figure 3 In some embodiments, the on / off element of the control mechanism 3 is used to control the on / off state of the pipeline, and the detection element is used to detect whether the adsorption surface 221 impacts the building wall. The controller controls the on / off element through the detection signal of the detection element. The on / off element can be a one-way valve, an electromagnetic shut-off valve, or an electromagnetic diaphragm valve, etc. In this embodiment, a one-way valve is used to ensure unidirectional airflow and maintain the negative pressure adsorption effect of the adsorption hole 23.

[0044] The controller receives signals from the detection device, judges the signals, and controls the on / off state of the switching device. The controller can be a microcontroller, programmable logic controller, or digital signal processor, etc.

[0045] The detection element is used to detect whether the adsorption surface 221 impacts the building wall. The detection element can be a distance sensor, proximity switch, strain gauge, or accelerometer, etc. In other words, the detection element can determine whether the adsorption surface 221 impacts the building wall by detecting the distance between it and the wall, the acceleration of the adsorption element 22, the acceleration of the housing 1, or the deformation of the adsorption element 22, etc. Of course, to ensure detection effectiveness, multiple detection elements can be provided. The detection elements can use the same or different sensor combinations to comprehensively determine whether the adsorption element 22 impacts the building wall, reducing the possibility of misoperation.

[0046] Reference Figures 1-4In some embodiments, a through hole 13 is provided through the wall surface 12, and the adsorption member 22 is movably disposed within the through hole 13; a buffer mechanism 4 is provided in the accommodating cavity 11, and the buffer mechanism 4 is connected to the adsorption member 22. The through hole 13 guides and limits the movement of the adsorption member 22, so that when the adsorption member 22 impacts the building wall, it can move along the opening direction of the through hole 13, thereby decomposing the impact force in any direction into a controllable compression, further improving the detection effect of the detection member. In addition, through the movement of the adsorption member 22 and the setting of the buffer mechanism 4, when the adsorption member 22 impacts the building wall and is squeezed back, the impact force can be absorbed by the buffer mechanism 4 and then transferred to the housing 1, thereby reducing the peak impact force on the housing 1, thereby reducing the overall impact acceleration of the aerial work platform, and ensuring the stability and safety of the personnel standing on the aerial work platform.

[0047] In some embodiments, the adsorption mechanism 2 further includes a connector 24, the opposite sides of which are connected to the adsorption element 22 and the buffer mechanism 4, respectively. The adsorption element 22 is made of an elastically compressible material, allowing it to undergo elastic deformation upon impact and compression to absorb impact energy. The connector 24 connects the adsorption element 22 and the buffer mechanism 4. The connector 24 can be made of a rigid material to ensure effective connection with the buffer mechanism 4. The adsorption element 22 can be made of a flexible material, such as sponge, foam, elastic foam, rubber, or silicone, so that after impact with the building wall, in addition to the overall movement of the adsorption element 22 along the through hole 13, the adsorption element 22 itself can also deform to a certain extent. The adsorption element 22 can absorb impact energy through its own deformation at the moment of impact, further improving the buffering effect.

[0048] Combination Figure 5 and Figure 12 Furthermore, the adsorption hole 23 penetrates the adsorption element 22, and a cavity 25 is formed inside the connector 24. Both ends of the pipeline are connected to the vacuum tank 21 and the cavity 25, respectively. Multiple flow holes 26 are provided on the side of the connector 24 that is in contact with the adsorption element 22. One end of each flow hole 26 communicates with the cavity 25, and the other end corresponds to each adsorption hole 23. The adsorption holes 23 are sequentially connected to the vacuum tank 21 through the flow holes 26, the cavity 25, and the pipeline. By connecting the pipeline to the cavity 25 and then providing flow holes 26 on the connector 24 to communicate with the adsorption holes 23, it is ensured that when the adsorption element 22 impacts the building wall, the deformation of the adsorption element 22 itself will not affect the connectivity of the pipeline or the reliability of the connection with the vacuum tank 21, further ensuring the reliability of the negative pressure adsorption of the adsorption element 22.

[0049] By connecting each flow hole 26 to the cavity 25, and the cavity 25 to the vacuum tank 21 through the pipeline, the negative pressure of each flow hole 26 is established synchronously, that is, the negative pressure environment of each adsorption hole 23 is established synchronously, avoiding local stress concentration caused by sequential adsorption, thereby ensuring uniform negative pressure adsorption force on the building wall.

[0050] Reference Figure 3 , Figure 6 and Figure 12 Optionally, the cross-sectional dimension of the adsorption hole 23 is larger than that of the flow hole 26. After the adsorption surface 221 of the adsorption element 22 impacts the building wall, the switching element opens the pipeline, connecting the vacuum tank 21 to the cavity 25, allowing the air in the adsorption hole 23 to flow sequentially through the flow hole 26, the cavity 25, and the pipeline into the vacuum tank 21. During this process, because the cross-sectional dimension of the adsorption hole 23 is larger than that of the flow hole 26, the air in the adsorption hole 23 is in a low-velocity, high-static-pressure state. When it enters the flow hole 26, the cross-sectional dimension suddenly decreases, the flow velocity increases, and the pressure drops, causing the residual gas pressure on the adsorption hole 23 side to drop rapidly, thereby quickly establishing a vacuum environment.

[0051] In addition, since the cross-sectional size of the flow hole 26 is smaller than that of the adsorption hole 23, the air velocity increases when it flows in the flow hole 26. This can also peel off and carry away the dust and other particles attached to the adsorption hole 23. The dust enters the cavity 25 after passing through the flow hole 26 with the high-speed airflow. It settles due to the increased cross-sectional area of ​​the cavity 25, thus avoiding clogging of the flow hole 26. While achieving the adsorption effect, it also plays a self-cleaning role.

[0052] Meanwhile, setting the cross-sectional size of the adsorption hole 23 to be larger than that of the flow hole 26 facilitates the opening of the adsorption hole 23 and the flow hole 26, allowing them to be integrally formed during injection molding. Their demolding direction is consistent with the axial direction of the adsorption hole 23, eliminating the need for lateral core pulling, reducing mold complexity, and ensuring the reliability of the connection and sealing between the adsorption component 22 and the connecting component 24.

[0053] It is understood that the cross-sectional shapes of the adsorption orifice 23 and the flow orifice 26 are not limited in this embodiment; the cross-sectional shapes of the adsorption orifice 23 and the flow orifice 26 can be similar or completely different. In this embodiment, the cross-sectional dimension of the flow orifice 26 is circular, and the cross-sectional shape of the adsorption orifice 23 is a long racetrack shape. In addition, to ensure the adsorption effect, the flow orifice 26 is located in the middle of the adsorption orifice 23.

[0054] Reference Figures 3-11In some embodiments, the buffer mechanism 4 includes a fixed rod 41 and a transmission component 42. The fixed rod 41 is disposed within the accommodating cavity 11 and fixedly connected to the housing 1, and the axial direction of the fixed rod 41 is perpendicular to the moving direction of the adsorption member 22; the transmission component 42 includes a connecting rod 421, an elastic member 422, and a sleeve 423, both of which are sleeved on the fixed rod 41, and the two ends of the elastic member 422 are respectively connected to the sleeve 423 and the fixed rod 41; the first end of the connecting rod 421 is hinged to the sleeve 423, the second end of the connecting rod 421 is movably connected to the connecting member 24, and the detection member is disposed on the sleeve 423.

[0055] The detection element is mounted on the sleeve 423, and the movement of the detection sleeve 423, connected by the connecting rod 421, allows the impact of the adsorption element 22 to be determined. Since the axis of the fixing rod 41 is perpendicular to the direction of movement of the adsorption element 22, when the adsorption element 22 impacts the building wall and is forced back, the connecting rod 421 pushes the sleeve 423, causing the sleeve 423 to move along the axis of the fixing rod 41, thus changing the measurement direction. Furthermore, according to the geometric closure equation, this arrangement can amplify the detection of changes in the movement of the adsorption element 22, thereby improving the detection sensitivity.

[0056] An elastic element 422 is sleeved on the fixed rod 41. The two ends of the elastic element 422 are connected to the sleeve 423 and the fixed rod 41, respectively. The elastic element 422 provides some orientation for the movement of the sleeve 423 under force, and also provides some buffering after the sleeve 423 moves under force, further ensuring the reliability of the overall device. The elastic element 422 can be made of materials such as a spring, torsion spring, rubber, or silicone. The detection element can be made of materials such as a distance sensor or an accelerometer. When the detection element is an accelerometer, it is mounted on the sleeve 423; when it is a distance sensor, it is mounted on the sleeve 423 and used to detect the distance between the sleeve 423 and the end of the fixed rod 41.

[0057] Furthermore, in order to avoid the elastic element 422 affecting the movement of the sleeve 423 and the detection of the sleeve 423 displacement, the elastic element 422 is in a relaxed state under normal operation. Moreover, after the sleeve 423 has moved a certain distance, the continued movement of the sleeve 423 will compress the elastic element 422. This can prevent the elastic element 422 from affecting the movement of the sleeve 423 and thus affecting the detection of the detection element, while also ensuring the buffering effect of the elastic element 422.

[0058] Reference Figures 8-12Optionally, two transmission components 42 are spaced apart along the axial direction of the fixed rod 41, and two elastic elements 422 are respectively disposed on opposite sides of the two sleeves 423; each sleeve 423 is provided with a detection element. The arrangement of two sets of transmission components 42 can improve the adsorption effect of the adsorption element 22 and prevent the adsorption element 22 from tilting due to unilateral support after impacting the building wall, thus affecting the adsorption effect.

[0059] Of course, the buffer mechanism 4 can also be provided in two or more sets, which are movably connected to different positions of the connector 24 by multiple connecting rods 421, thereby achieving multi-point support when adsorbing with the building wall, ensuring the stability of the overall structure of the adsorption component 22, and the reliability of negative pressure adsorption on the building wall. In this embodiment, the buffer mechanism 4 is provided in two sets, with each connecting rod 421 movably connected to each corner of the connector 24.

[0060] Reference Figures 9-12 In some embodiments, the buffer mechanism 4 further includes a mounting component 43, through which the connecting rod 421 is movably connected to the connecting member 24. The mounting component 43 includes a first mounting member 431 and a second mounting member 432. The first mounting member 431 is hinged to the second end of the connecting rod 421. The second mounting member 432 is disposed on the connecting member 24 and connected to the first mounting member 431 via a locking attachment 433. The connecting member 24 has a sliding groove 241 extending axially along the fixed rod 41, and the second mounting member 432 is slidably disposed within the sliding groove 241.

[0061] When the adsorption element 22 is displaced along the opening direction of the through hole 13, the second mounting element 432 slides within the groove 241 along the axial direction of the fixed rod 41. Under the connecting action of the connecting rod 421, the sleeve 423 also slides along the axial direction of the fixed rod 41. The movement directions of the second mounting element 432 and the sleeve 423 are opposite. Since the length of the connecting rod 421 is fixed, the effective swing arm is about half the length of the connecting rod 421. Assuming that the displacement change of the adsorption element 22 remains constant, the connecting rod 421 will generate a larger rotation angle, which amplifies the initial segment of the displacement of the sleeve 423. That is, when the impact has just occurred and the displacement of the adsorption element 22 is still very small, the proportion of the displacement change output by the sleeve 423 relative to the displacement change of the adsorption element 22 is amplified, thereby realizing the amplification of the small signal and further improving the detection sensitivity.

[0062] Optionally, the second mounting component 432 is detachably connected to the first mounting component 431 via a locking accessory 433. The locking accessory 433 can be a bolt, screw, or clip, etc. When a certain amount of buffering is performed, the locking accessory 433 can be loosened, and the buffer mechanism 4 can be removed from the housing 1 for quick replacement, which greatly reduces the maintenance time of the device and reduces the downtime of the aerial work platform.

[0063] In summary, the anti-collision safety device for aerial work platforms provided in this embodiment, when encountering extreme wind conditions, transmits a signal to the controller when the detection value of the detection component exceeds a preset threshold. The controller outputs a signal to open the switch, connecting the vacuum tank 21 with the adsorption hole 23. The adsorption hole 23 applies negative pressure to the building wall, thereby stably adsorbing the anti-collision safety device onto the building wall. This effectively avoids continuous collisions between the aerial work platform and the building wall, providing workers with sufficient emergency protection time, improving the safety of personnel inside the aerial work platform, reducing collision losses, and lowering operational risks.

[0064] In addition, the anti-collision safety device provided in this embodiment should be vacuumed by vacuum tank 21, tested by buffer mechanism 4, and calibrated after each use to ensure the reliability of the anti-collision safety device.

[0065] Reference Figures 1-12 This embodiment also provides a high-altitude work equipment, which includes a suspended platform and the aforementioned anti-collision safety device for the suspended platform. The suspended platform includes a work platform and a suspension drive device. The suspension drive device is used to drive the lifting and lowering of the work platform. The suspension drive device is electrically connected to the controller, and the controller controls the start and stop of the suspension drive device according to the detection signal of the detection device. When the detection device detects that the adsorption surface 221 impacts the building wall, the controller controls the opening of the switch, adsorbing the adsorption surface 221 with negative pressure onto the building wall. At the same time, the controller controls the suspension drive device to shut down, turning off the power of the work platform, and stably adsorbing the work platform onto the building exterior wall, preventing safety risks caused by continuous collisions, and providing time for personnel inside the work platform to take emergency protection measures.

[0066] Furthermore, the anti-collision safety device can be installed at any location on the work platform, such as the top, side, or bottom. When the anti-collision safety device is installed on the side of the work platform, two anti-collision safety devices can be installed, one on each side of the work platform, to ensure the stability of the work platform.

[0067] In this embodiment, the anti-collision safety device is installed at the bottom of the work platform, which can lower the center of gravity of the work platform and reduce the swaying amplitude of the work platform in windy weather, thereby improving safety and stability.

[0068] In some embodiments, the working platform is provided with an adsorption release component, which is electrically connected to the controller to regulate the opening and closing of the on / off element. The adsorption release component is used to restore the air environment within the adsorption hole 23 and release the negative pressure adsorption of the adsorption element 22. The adsorption release component can be triggered manually by a button or remotely by remote control to meet the usage requirements of different application scenarios.

[0069] In some embodiments, the anti-collision safety device can also be rotatably mounted on the bottom of the work platform. The anti-collision mount can be connected by means such as a rotating shaft or flange, and driven and controlled by a rotation driver. The controller is electrically connected to the rotation driver. Detection elements are also spaced around the periphery of the housing 1. The detection elements located around the periphery of the housing 1 can be laser rangefinders or proximity switches, etc. In extreme weather conditions, the housing 1 swings with the wind. Depending on the different structural forms of the aerial work platform, it is impossible to guarantee which side of the housing 1 will collide with the building wall during the swinging process. At this time, during the swinging process of the housing 1, the detection elements located around the periphery of the housing 1 can monitor in real time which side of the housing 1 is closer to the building wall. Then, the controller drives the rotation driver to rotate the wall-facing side 12 of the housing 1 to the side facing the building wall, so as to ensure that during the swinging process of the housing 1, the wall-facing side 12 of the housing 1 always faces the building wall. This ensures that in the event of a collision, the adsorption component 22 of the anti-collision safety device can first collide with the building wall and perform negative pressure adsorption.

[0070] Furthermore, the shell 1 can be designed as a cylindrical structure to ensure the reliability and stability of the rotation of the shell 1 and to avoid the collision between the edges and corners of the shell 1 and the building wall during the rotation process.
