Description

Technical Field

[0001] The present invention relates to the technical field of construction protection platforms, and more specifically, to an anti-falling and anti-tilting device for an external climbing type construction protection platform. Background Art

[0002] With the acceleration of urbanization and the rise of high-rise buildings, external climbing construction protection platforms are widely used as an efficient construction method. However, since such platforms are often exposed to high-altitude environments, facing various adverse conditions such as wind speed and temperature changes, they are very likely to cause the risk of falling or tilting, which seriously threatens the lives of construction workers. Therefore, in order to ensure the safe and smooth progress of the construction process, effective anti-fall and anti-tilt devices must be installed on the external climbing construction protection platform. There are currently two main types of anti-fall and anti-tilt devices on the market: one is an active anti-fall and anti-tilt device; the other is a passive anti-fall and anti-tilt device. The former automatically activates the braking mechanism after sensing the danger signal through the sensor to prevent the platform from further sliding or flipping; the latter is when the platform deviates from the preset track, it is forced to pull it back to the correct position through a mechanical structure.

[0003] The passive anti-fall and anti-tilt device used on the external climbing construction protection platform is usually composed of a frame structure, a lifting mechanism, a power device, an anti-tilt device, an anti-fall device and a lifting synchronous control system. When the protection platform descends rapidly, the ladder fixed on the protection platform prompts the anti-fall pendulum block of the anti-fall device to lock the slide rail, thereby protecting the protection platform from falling and tilting.

[0004] In the process of locking the slide rail with the anti-fall pendulum block, the protection platform will have a braking distance for a period of time. Due to the long braking time, the protection platform is prone to shaking due to the rapid descent. This shaking may cause the construction workers on the platform to lean forward and backward, and collide with the protection net or other brackets on the protection platform, causing physical injuries, which is not conducive to the normal progress of construction work.

[0042] The following is a detailed description of the anti-falling and anti-tilting device of an external climbing construction protection platform provided by the present invention in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the present invention.

[0043] like Figures 1 to 7 As shown, an embodiment of the present invention provides an anti-falling and anti-tilting device for an external climbing construction protection platform, comprising a guide rail frame 1, a support frame 2 fixedly connected to a wall is provided on one side of the guide rail frame 1, a double-claw bracket 3 is fixedly connected to the side of the support frame 2 close to the guide rail frame 1, a limiting mechanism 4 for preventing the guide rail frame 1 from falling is provided inside the double-claw bracket 3, the limiting mechanism 4 comprises a five-claw rotating wheel 42 arranged inside the double-claw bracket 3 for preventing the guide rail frame 1 from falling and an anti-falling pendulum block 44 used in conjunction therewith, a baffle 45 for blocking the anti-falling pendulum block 44 from excessively rotating is fixedly connected to the top of the double-claw bracket 3, a control mechanism 7 for detecting the frequency of the anti-falling pendulum block 44 hitting the baffle 45 is provided on one side of the upper surface of the baffle 45, and a vertical plate 8 is fixedly connected to the other side of the upper surface of the baffle 45;

[0044] A driving mechanism 9 is provided at the middle of the outer surface of the vertical plate 8 near the guide rail frame 1, and a clamping mechanism 10 is provided on the outer side of the vertical plate 8 for use in conjunction with the driving mechanism 9 to buffer the guide rail frame 1 from falling too fast.

[0045] Among them, the clamping mechanism 10 includes a first limit seat 101 and a second limit seat 103 fixedly connected to the two ends of the outer side of the vertical plate 8, the first limit seat 101 has a gear 102 internally rotatably connected to one end, and the second limit seat 103 has a sector gear 104 meshing with the gear 102 internally arranged at one end, the sector gear 104 and one side of the outer cylindrical surface of the sector gear 104 are fixedly connected with a support arm 105, and one end of the support arm 105 is fixedly connected with a clamping roller 106 for clamping the guide rail frame 1.

[0046] In order to solve the problem that the protection platform will have a braking distance for a period of time during the locking of the slide rail by the existing anti-falling equipment. Due to the long braking time, the shaking phenomenon caused by the rapid descent of the protection platform is likely to occur. This shaking may cause the construction personnel on the platform to lean forward and backward, and collide with the protection net or other brackets on the protection platform, thereby causing physical injuries, which is not conducive to the normal progress of the construction work. Now, the above-mentioned technical solution is adopted to solve the problem. The above-mentioned technical solution is mainly composed of an anti-falling pendulum block 44, a control mechanism 7, a driving mechanism 9, and a clamping mechanism 10. When the external climbing construction protection platform descends rapidly, the guide rail frame 1 fixedly installed on the protection platform will prompt the anti-falling pendulum block 44 to lock the guide rail frame 1, thereby protecting the protection platform from falling and tilting. At this time, the anti-falling pendulum block 44 will hit the baffle 45, generate vibration and transmit it to the control mechanism 7. After receiving the vibration signal, the control mechanism 7 determines whether it reaches the predetermined threshold. If the vibration exceeds the predetermined threshold, it means that the protection platform is experiencing a rapid descent and may be out of control. At this time, the control mechanism 7 will issue an instruction to activate the driving mechanism 9. After the driving mechanism 9 is activated, the gear 102 starts to rotate. The rotation of the gear 102 drives the meshing sector gear 104 to move together. The movement of the sector gear 104 causes the arm 105 connected thereto to move, so that the clamping roller 106 at the end of the arm 105 contracts inward, exerts pressure on the guide rail frame 1, and plays a decelerating role. At the same time, the clamping force of the clamping roller 106 can be adjusted according to actual conditions to ensure that the falling speed of the guide rail frame 1 can be effectively slowed down without causing damage to it. In addition, the presence of the baffle 45 can prevent the anti-fall pendulum block 44 from rotating excessively, ensuring that it is always in the appropriate position so that it can play a role again when necessary. During use, the device greatly reduces the possibility of the protection platform losing control through multiple insurance measures (anti-fall pendulum block 44, clamping mechanism 10, etc.), and improves the safety factor of construction personnel.

[0047] At the same time, the control mechanism 7 can monitor the action state of the anti-falling pendulum block 44 in real time, and take action immediately once an abnormality is detected, thereby shortening the reaction time. The clamping mechanism 10 effectively alleviates the impact force caused by high-speed descent, provides comprehensive safety protection for the external climbing construction protection platform, and reduces physical harm to construction workers.

[0048] like Figure 2 , Figure 6 As shown, the driving mechanism 9 includes a servo motor 91 fixedly connected to the middle of the outer side of the vertical plate 8, the output end of the servo motor 91 is fixedly connected to a threaded rod 92, the outer cylindrical surface of the threaded rod 92 is rotatably connected to a threaded slide 93, both ends of one side of the outer surface of the threaded slide 93 are fixedly connected to a fixed plate 94, and one side of the outer surface of the fixed plate 94 is provided with a tooth plate 95 meshing with the gear 102.

[0049] like Figure 2 , Figure 3 , Figure 4 As shown, the limiting mechanism 4 also includes a second support rod 43 fixedly connected to the upper end of the inner part of the double-card bracket 3, and the outer cylindrical surface of the second support rod 43 is rotatably connected to an anti-fall pendulum block 44. A first support rod 41 is fixedly connected to the middle of the inner part of the double-card bracket 3, and a five-claw rotating wheel 42 for driving the anti-fall pendulum block 44 to rotate is rotatably connected to the middle of the outer cylindrical surface of the first support rod 41.

[0050] When the guide rail frame 1 descends rapidly, the steps in the guide rail frame 1 will drive the five-claw wheel 42 to rotate on the first support rod 41, and at the same time, the five-claw wheel 42 will turn the anti-falling pendulum block 44 to rotate on the second support rod 43, and the anti-falling pendulum block 44 will be used to lock the guide rail frame 1, so as to prevent the protection platform from falling and tilting. At this time, the anti-falling pendulum block 44 will hit the baffle 45, generate vibration and transmit it to the control mechanism 7. After receiving the vibration signal, the control mechanism 7 determines whether it reaches the predetermined threshold. If the vibration exceeds the predetermined threshold, it means that the protection platform is experiencing a rapid descent and may be out of control. At this time, the control mechanism 7 will issue an instruction to activate the servo motor 91. After the servo motor 91 is started, the threaded rod 92 drives the threaded slide 93 connected to it for rotation to move. When the threaded slide 93 moves, the fixed plate 94 fixed at both ends of one side of its outer surface also moves accordingly. Since the fixed plate 94 is provided with a tooth plate 95 meshing with the gear 102, the movement of the tooth plate 95 will cause the gear 102 to rotate. The rotation of the gear 102 will drive the fan-shaped gear 104 meshing with it to move at the same time, that is, drive the support arm 105 to tighten inward. The movement of the support arm 105 eventually causes the clamping roller 106 to apply pressure to the guide rail frame 1, which has the effect of decelerating. During the above operation, driven by the servo motor 91 and the threaded rod 92, the system can respond quickly and start the deceleration mechanism, shortening the time interval from detection to braking. At the same time, the clamping mechanism 10 driven by the servo motor 91 serves as a second line of defense, providing double protection to prevent accidents. And by precisely controlling the rotation of the servo motor 91, the speed of the threaded slide 93 can be adjusted, and then the strength of the clamping roller 106 can be adjusted to achieve a smooth deceleration effect and reduce shaking caused by excessive braking.

[0051] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, the control mechanism 7 includes a limit frame 71 fixedly connected to one side of the upper surface of the baffle 45, a slide rod 72 is fixedly connected to the middle of the bottom of the limit frame 71, a blocking disc is fixedly connected to the bottom of the slide rod 72, a sleeve 73 is slidably connected to the outer cylindrical surface of the slide rod 72, a circular groove is provided inside the baffle 45 to facilitate the movement of the sleeve 73, the bottom of the sleeve 73 is located on both sides of the slide rod 72 and is fixedly connected to connecting rods 74, the bottoms of the two connecting rods 74 are jointly fixedly connected to a buffer plate 75 for buffering the anti-fall pendulum block 44, and a frequency switch sensor 77 for controlling the start of the servo motor 91 is provided on the top of the limit frame 71.

[0052] like Figure 2 , Figure 4 , Figure 5 As shown, both ends of the upper surface of the buffer plate 75 are fixedly connected with spring rings 76 for enhancing the buffering of the buffer plate 75; and one end of the spring ring 76 is fixedly connected to the upper surface of the buffer plate 75, and the other end of the spring ring 76 is fixedly connected to the bottom of the baffle 45.

[0053] When the guide rail frame 1 descends rapidly, the anti-falling pendulum block 44 will rotate on the second support rod 43 and eventually hit the baffle 45. The impact will generate vibration, which will be transmitted to the limit frame 71 fixed on the baffle 45. The slide rod 72 and the sliding sleeve 73 in the limit frame 71 constitute a movable system, in which the sliding sleeve 73 can slide freely up and down on the slide rod 72. When the anti-falling pendulum block 44 hits the baffle 45, the sliding sleeve 73 moves upward under the influence of the impact force, compressing the spring coil 76, which not only plays a buffering role, but also helps to absorb part of the energy and reduce the impact force. The triggering of the frequency switch sensor 77 As the sliding sleeve 73 rises, it will contact the frequency switch sensor 77 at the top of the limit frame 71. After the frequency switch sensor 77 senses this change, it sends a signal to the servo motor 91 to instruct it to start. After the servo motor 91 is started, a series of transmission elements such as threaded rods 92, threaded slide plates 93 drive the clamping mechanism 10 to apply additional clamping pressure to the guide rail frame 1 to further reduce its descending speed. During the above operation, the spring coil 76 effectively disperses and absorbs the impact force, reducing the possibility of damage to the device itself.

[0054] like Figure 2 , Figure 4 , Figure 5 As shown, an L-shaped support plate 5 is fixedly connected to the other side of the upper surface of the baffle 45, and a unloading component 6 for unloading the guide rail frame 1 is provided on the side of the upper surface of the L-shaped support plate 5 close to the support frame 2. The unloading component 6 includes a U-shaped frame 61 fixedly connected to one side of the upper surface of the L-shaped support plate 5, and the U-shaped frame 61 is hinged with a rotating seat, and a hydraulic rod 62 is fixedly connected to one side of the outer surface of the rotating seat, and one end of the hydraulic rod 62 is fixedly connected to a U-shaped clamping seat 63.

[0055] Among them, the configured unloading assembly 6 is usually in an inactive state, at which time the U-shaped holder 63 is away from the guide rail frame 1 and does not affect the normal lifting operation. When the guide rail frame 1 needs to be unloaded, it may be to replace or repair some components of the guide rail frame 1, or for other reasons, the load-bearing function of the guide rail frame 1 needs to be temporarily released. The hydraulic rod 62 can be started to start extending. One end of the hydraulic rod 62 is fixed to the rotating seat, and the other end is connected to the U-shaped holder 63. As the hydraulic rod 62 extends, the U-shaped holder 63 gradually approaches and finally locks to the designated position of the guide rail frame 1. The U-shaped holder 63 is used to enable it to firmly grasp the guide rail frame 1 to ensure that the guide rail frame 1 remains stable during unloading. After the U-shaped holder 63 is successfully locked, the weight of the guide rail frame 1 is transferred to the unloading assembly 6, completing the unloading task. At this time, the guide rail frame 1 can be subjected to necessary maintenance or replacement work. The provision of the unloading assembly 6 not only ensures that the guide rail frame 1 remains stable during maintenance or replacement operations, thus avoiding possible dangerous situations, but also performs unloading in an automated manner, thus saving manual operation time and improving work efficiency.

[0056] like Figure 1 , Figure 2 , Figure 7 As shown, side panels 11 are fixedly connected to both sides of the outer surface of the support frame 2, and a buffer mechanism 12 is provided on one side of the side panel 11 close to the guide rail frame 1. The buffer mechanism 12 includes a first support seat 121 and a second support seat 130 fixedly connected to one side of the outer surface of the side panel 11, and one end of the inner side of the first support seat 121 and the second support seat 130 is fixedly connected to a locking rod 122, and the outer circular surface of the locking rod 122 inside the first support seat 121 is rotatably connected to a gear roller 123, and a locking sleeve 124 used in conjunction with the locking rod 122 is provided on one side of the outer surface of the gear roller 123.

[0057] like Figure 1 , Figure 2 , Figure 7 As shown, the outer circumferential surface of the gear roller 123 is provided with circumferentially arranged slots; a circumferentially arranged damping blocks are fixedly connected to one side of the gear roller 123 close to the locking sleeve 124; and the outer circumferential surface of the gear roller 123 is tangent to the inner wall of the guide rail frame 1.

[0058] When the guide rail frame 1 descends rapidly, the guide rail frame 1 will push the gear roller 123 to rotate on the locking rod 122, and the gear roller 123 rolls along the slide groove of the guide rail frame 1. Since the gear roller 123 is tangent to the guide rail frame 1, the gear roller 123 can provide a certain damping effect during the movement of the guide rail frame 1, thereby slowing down the speed of the guide rail frame 1. At the same time, the circumferentially arranged damping blocks on the outer surface of the gear roller 123 are used in conjunction with the locking sleeve 124 to increase the contact area and friction between the two, further enhance the damping effect, and effectively prevent the guide rail frame 1 from losing control due to excessive descent. In addition, it also helps to evenly distribute the pressure of the guide rail frame 1 during the descent process, avoiding structural damage caused by local excessive concentration. In this way, not only can the operating stability of the overall system be improved, but also the service life of each component can be extended and the maintenance cost can be reduced.

[0059] like Figure 2 , Figure 7 As shown, the buffer mechanism 12 also includes a roller 125 rotatably connected to the locking rod 122 inside the second support seat 130, and the top of the outer cylindrical surface of the roller 125 is fixedly connected to an arc block 126 tangent to the gear roller 123, and a limiting hole 127 is opened on the side of the outer cylindrical surface of the roller 125 close to the guide rail frame 1, and a spring telescopic rod 128 is fixedly connected to the inside of the limiting hole 127, and a clamping block 129 is fixedly connected to one end of the spring telescopic rod 128.

[0060] like Figure 2 , Figure 7 As shown, a torsion spring for returning the roller 125 is arranged on the locking rod 122 inside the second support seat 130 .

[0061] When the guide rail frame 1 is affected by external force (such as rapid descent), the guide rail frame 1 will push the gear roller 123 to rotate along the locking rod 122. At the same time, the damping block on the gear roller 123 contacts the inner wall of the guide rail frame 1, generating friction, which helps to slow down the movement speed of the guide rail frame 1. In addition, the rotation of the gear roller 123 will also drive the arc block 126 tangent to it, thereby causing the roller 125 to rotate. While the roller 125 rotates, the block 129 on it will extend outward under the action of the spring telescopic rod 128 and enter a groove of the guide rail frame 1 to prevent the guide rail frame 1 from continuing to move rapidly. When the external force disappears, the torsion spring will cause the roller 125 to reset, so that the block 129 will be separated from the groove of the guide rail frame 1 and return to its original state. In the above operation process, through the combination of the gear roller 123 and the damping block, additional friction can be provided when the guide rail frame 1 moves rapidly, reducing its speed, thereby improving the safety of the system. At the same time, the arrangement of the spring telescopic rod 128 and the block 129 can quickly lock the position of the guide rail frame 1 in an emergency to prevent accidental falling off. The existence of the torsion spring ensures that the roller 125 can automatically reset when locking is not required, which simplifies the operation steps and enhances the convenience of the device.

[0062] When the present invention is in use, when the guide frame 1 on the protection platform triggers the anti-falling and tilting protection for some reason (such as rapid descent), the step in the guide frame 1 will drive the five-claw wheel 42 to rotate on the first support rod 41. The rotation of the five-claw wheel 42 will move the anti-falling pendulum block 44 to rotate on the second support rod 43, and the guide frame 1 is initially locked by the anti-falling pendulum block 44, so as to perform anti-falling and tilting protection on the protection platform. When the anti-falling pendulum block 44 hits the baffle 45, vibration will be generated, and this vibration will be transmitted to the limit frame 71 fixed on the baffle 45. The slide rod 72 and the slide sleeve 73 in the limit frame 71 constitute a movable system, and the slide sleeve 73 can slide freely up and down on the slide rod 72. When the anti-falling pendulum block 44 hits the baffle 45, the slide sleeve 73 moves upward under the influence of the impact force, compressing the spring coil 76, playing a buffering role and helping to absorb part of the energy. As the slide sleeve 73 rises, it will contact the frequency switch sensor 77 at the top of the limit frame 71. After the frequency switch sensor 77 senses this change, it will send a signal to the servo motor 91 to instruct it to start. If the vibration exceeds the predetermined threshold, it means that the protection platform is experiencing a rapid descent and may be out of control. After the servo motor 91 is started, the threaded rod 92 drives the threaded slide 93 connected to it for rotation to move. When the threaded slide 93 moves, the fixed plate 94 fixed at both ends of one side of its outer surface also moves accordingly. The fixed plate 94 is provided with a toothed plate 95 meshing with the gear 102, and the movement of the toothed plate 95 causes the gear 102 to rotate. The rotation of the gear 102 will drive the fan gear 104 meshing with it to move at the same time, and then drive the support arm 105 to tighten inward. The movement of the support arm 105 eventually causes the clamping roller 106 to apply pressure to the guide frame 1, which plays a role in deceleration. At the same time, the guide frame 1 will push the toothed roller 123 to rotate on the locking rod 122, and the toothed roller 123 rolls along the slide groove of the guide frame 1 to provide a damping effect. The circumferentially arranged damping blocks on the outer circumferential surface of the toothed roller 123 are used in conjunction with the locking sleeve 124 to increase the contact area and friction between the two, further enhance the damping effect, and effectively prevent the guide frame 1 from losing control due to too fast a descent. The rotation of the toothed roller 123 will also drive the arc block 126 tangent to it, thereby rotating the roller 125. While the roller 125 rotates, the block 129 on it will extend outward under the action of the spring telescopic rod 128 and enter a groove of the guide frame 1 to prevent the guide frame 1 from continuing to move quickly. When the external force disappears, the torsion spring will cause the roller 125 to reset, so that the block 129 will be separated from the groove of the guide frame 1 and return to its original state.
