Description

Technical Field

[0001] The present invention relates to the technical field of building engineering, and in particular to a corridor lifting device with a wind speed dynamic early warning function and a use method thereof. Background Art

[0002] A corridor is a type of building in ancient times, that is, a connecting structure between buildings that can realize the interconnection between buildings. In the definition of modern architecture, a corridor is a type of complex high-rise building structure system. It generally refers to two or several high-rise buildings connected by an overhead connector to meet the requirements of architectural shape and functional use. The connector is the corridor.

[0003] According to a corridor lifting wind-induced displacement adaptive adjustment device and construction method with patent publication number CN116575726A and publication date 2023-08-11, the device includes a track and a force transmission support. The track is fixed on the original structure from bottom to top, one end of the force transmission support is fixedly connected to the corridor component, and the other end is connected to a pulley that slides with the track, and a self-adjusting telescopic device is arranged between the pulley and the force transmission support. This invention can solve the shaking problem caused by the wind during the lifting construction of the corridor structure. The control device has a simple structure and is easy to install and disassemble. At the same time, the control device can adjust itself to effectively control the shaking of the corridor structure during the lifting process without manual operation. This device uses a self-adjusting telescopic device to enable this device to adjust the distance between the corridor structure and the device according to the wind force, thereby reducing the influence of wind on the corridor structure during the lifting process, so that the shaking amplitude of the corridor structure will not be too large. However, this device still has limitations: no wind speed monitoring device is installed on this device, and the self-adjusting telescopic device cannot accurately monitor the wind speed, so that the distance between the corridor structure and the device cannot be adjusted in time according to the wind force. In extreme weather, since the self-adjusting telescopic device cannot adjust the distance between the corridor structure and the device in time, the corridor structure is easily affected by wind and shakes violently, which greatly increases the possibility of accidents and reduces safety. And as the lifting height continues to increase, the wind force value of each height node will also be different. In the process of lifting the corridor structure, wind speed monitoring should be continuously performed to prevent accidents.

[0004] Therefore, we are in urgent need of a corridor lifting device with a dynamic wind speed warning function and a method of use. Summary of the invention

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a corridor lifting device with a wind speed dynamic warning function and a use method thereof.

The hanger is connected to the lower end of the steel strand. The first steel wire rope is connected to both sides of the hanger through the rope shaft. The lower end of the first steel wire rope is connected with a hook. The dynamic wind speed monitoring mechanism includes an adjusting part symmetrically installed on the hanger and a second wind speed monitor installed on the top of the adjusting part. The pulling mechanism includes a slide rail, a traveling frame and a tightening assembly. A traveling frame is slidably arranged on the slide rail. The traveling frame and the hanger are connected through a tightening assembly. The tightening assembly and the second wind speed monitor are both electrically connected to the controller.

[0007] Preferably, the tightening assembly includes a hydraulic tensioner and a second steel wire rope, the traveling frame is equipped with the hydraulic tensioner, the second steel wire rope is connected to the hydraulic tensioner, the tail end of the second steel wire rope is connected to the hanger, and the hydraulic tensioner is electrically connected to the controller.

Both the accompanying frame and the hanging frame are provided with a magnetic guide rail, an electromagnetic slider is slidably provided on the magnetic guide rail, the scissors-type telescopic frame is installed on the magnetic guide rail and the electromagnetic slider, and the electromagnetic slider is electrically connected to the controller.

[0009] Preferably, it also includes a high-position wind speed monitoring mechanism, which includes a mounting frame and a first wind speed monitor, the mounting frame is arranged on the lifting bracket; the first wind speed monitor is arranged on the mounting frame; the first wind speed monitor is electrically connected to the controller.

[0010] Preferably, a first indicator light is provided on the top of the mounting frame, and a second indicator light is provided on the top of the adjusting member, and both the first indicator light and the second indicator light are electrically connected to the controller.

[0011] Preferably, it also includes an adjustment mechanism, which includes a bidirectional threaded rod, a sliding member, a limiting ring and a nut. The bidirectional threaded rod is rotatably connected to the lower side of the hanger, and sliding members are slidably provided on both sides of the hanger. The two ends of the sliding member are respectively connected to the limiting ring and the nut. The first steel wire rope passes through the limiting ring, and the nut is threadedly connected to the bidirectional threaded rod.

[0012] Preferably, it also includes a winding mechanism, which includes a cylindrical gear, a worm wheel and a worm. There are two cylindrical gears, which are respectively connected to one end of the two rope shafts; the worm is rotatably connected to the middle of the hanger, and there are two worm wheels, which are arranged between the worm and the cylindrical gears, and the worm wheels are rotatably connected to the hanger; the worm wheels are respectively meshed with the cylindrical gears and the worm.

[0013] Preferably, it also includes auxiliary wheels, and auxiliary wheels are rotatably mounted on the opposite sides of the two limit rings.

[0014] A method for using a corridor lifting device with a wind speed dynamic warning function comprises the following steps: S1: Connect the lifting bracket to the embedded connector on the top of the floor truss, place the corridor component between the two floor trusses, fix the slide rail to the side of the two floor trusses where the corridor component needs to be connected through expansion bolts, the slide rail is parallel to the side of the floor truss, and the corridor component is fixed to the hook through the fixing piece; S2: Start the hydraulic lifter to lift the steel strand, the hoisting mechanism will move up, and the stabilizing mechanism will drive the accompanying frame upward along the slide rail, thereby lifting the corridor components; S3: During the lifting process of the corridor component, the first wind speed monitor and the second wind speed monitor continuously monitor the wind speed. When the wind speed is continuously increased, the signal is fed back to the controller. After receiving the early warning instruction, the controller drives the hydraulic tensioner to tighten the second steel wire rope, and applies tension to the hanger through the second steel wire rope, so that the corridor component rises steadily; S4: When the corridor components are lifted to the required height, turn off the hydraulic lifter, connect the corridor components to the steel connectors embedded in the floor trusses, remove the hooks, and disassemble the lifting brackets and slide rails from the floor trusses.

[0015] The present invention has the following beneficial effects: 1. By installing a dynamic wind speed monitoring mechanism, during the lifting process of the corridor components, the second wind speed monitor will continuously monitor the wind speed. When it is detected that the wind speed continues to increase, the controller controls the hydraulic tensioner to tighten the second steel wire rope according to the wind speed. The second steel wire rope will shorten the distance between the hanger and the floor truss, thereby reducing the influence of wind speed on the corridor components being lifted and reducing the lateral shaking amplitude of the corridor components.

[0016] 2. When it is monitored that the wind speed continues to increase, the controller controls the electromagnetic slider to be energized so that the electromagnetic slider is adsorbed on the magnetic guide rail. At this time, the scissor-type telescopic frame cannot be retracted, which reduces the lateral shaking amplitude of the corridor components and further reduces the risk of shaking. In cooperation with the pulling mechanism, it can be reinforced in multiple directions, so that the device can lift the corridor components smoothly even when the wind speed is high, thereby improving the utilization rate and work efficiency of the device.

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] Embodiment 1: A corridor lifting device with a wind speed dynamic warning function, such as Figure 1 , Figure 6 and Fig. 9, including a lifting bracket 2, a hydraulic lifter 31, a hoisting mechanism 4, a controller 33, a pulling mechanism 10 and a dynamic wind speed monitoring mechanism 6. The hydraulic lifter 31 is arranged on the top of the lifting bracket 2. The lifting bracket 2 is used to be connected to the embedded connecting piece of the floor truss 1. As the main supporting member of the device, its lower part is a triangular structure, which can stably support the device. A steel strand 32 is arranged on the hydraulic lifter 31. The hydraulic lifter 31 is used to lift the steel strand 32 to achieve the lifting operation of the corridor component 200. A controller 33 is installed on the top of the lifting bracket 2. The top of the controller 33 is provided with a protective plate protruding to the surroundings to play a role in rain and sun protection. The pulling mechanism 10 and the dynamic wind speed monitoring mechanism 6 are both connected to the hoisting mechanism 4 The hoisting mechanism 4 includes a hanger 41, a rope shaft 42, a first steel wire rope 43 and a hook 44. The hanger 41 is triangular in shape as a whole. The top of the hanger 41 is connected to the lower end of the steel strand 32. The rope shaft 42 is installed on both sides of the hanger 41 through a bearing seat. One end of the first steel wire rope 43 is connected to the middle of the rope shaft 42, and the other end of the first steel wire rope 43 is connected to the hook 44. The dynamic wind speed monitoring mechanism 6 includes an adjusting member and a second wind speed monitor 63. The adjusting member includes a telescopic rod 61 and a fastener 62. The telescopic rod 61 is provided with two, and the two telescopic rods 61 are respectively vertically connected to the two ends of the hanger 41. One telescopic rod 61 has two sections, one of which is connected to the hanger 41, and the other section is connected to the second wind speed monitor 63. The upper end of the telescopic rod 61 is an annular array A second indicator light 64 is arranged, and a fastener 62 is threadedly connected to the telescopic rod 61. In this embodiment, the fastener 62 is a bolt, and the telescopic rod 61 can be extended and retracted up and down to adjust the height of the second wind speed monitor 63, so that the second wind speed monitors 63 on both sides are at different heights, and wind force monitoring at multiple heights is realized. The fastener 62 is rotated, and the fastener 62 moves to the inside of the telescopic rod 61 to resist the inner rod to prevent the second wind speed monitor 63 from being displaced. The pulling mechanism 10 includes a slide rail 102, a traveling frame 103 and a tightening assembly. Screw holes are provided at both ends of the slide rail 102, which is convenient for the upper and lower slide rails 102 to be connected by bolts, and can be spliced ​​into a slide rail 102 of suitable length as needed. The slide rail 102 is installed in the slide rail 102 by expansion screws On the side of the floor truss 1, a traveling frame 103 is slidably arranged on the slide rail 102. The traveling frame 103 can slide up and down along the slide rail 102. The traveling frame 103 is connected to the hanger 41 through a tightening assembly. The tightening assembly is used to limit the position of the hanger 41, thereby stabilizing the corridor component 200. The tightening assembly includes a hydraulic tensioner 104 and a second steel wire rope 105. Four hydraulic tensioners 104 are evenly installed on the traveling frame 103. Each hydraulic tensioner 104 is connected to a second steel wire rope 105. The tail ends of the four second steel wire ropes 105 are respectively connected to four positions in the length direction of the hanger 41. The second indicator light 64, the hydraulic tensioner 104 and the second wind speed monitor 63 are all electrically connected to the controller 33.

[0031] like Figure 5 and Figure 7 As shown, it also includes a stabilizing mechanism 8, which includes a magnetic guide rail 81, a scissor-type telescopic frame 82 and an electromagnetic slider 83. The bottom of the accompanying frame 103 and the bottom of the hanger 41 are both provided with a magnetic guide rail 81, the material of the magnetic guide rail 81 is low carbon steel, the two magnetic guide rails 81 are arranged in parallel, and an electromagnetic slider 83 is slidably provided on the magnetic guide rail 81, and the electromagnetic slider 83 can slide axially along the magnetic guide rail 81. The two ends of one side of the scissor-type telescopic frame 82 are respectively rotatably mounted on one end of the two magnetic guide rails 81, and the two ends of the other side are respectively rotatably mounted on the two electromagnetic sliders 83. The electromagnetic slider 83 is electrically connected to the controller 33. When the hydraulic tensioner 104 tightens the second steel wire rope 105, the scissor-type telescopic frame 82 shrinks accordingly. At this time, the electromagnetic slider 83 is started to be adsorbed on the magnetic guide rail 81, which can further stabilize the corridor component 200 and reduce the impact of wind on the lifting operation.

[0032] like Figure 5 and Figure 7 As shown, it also includes a high-position wind speed monitoring mechanism 5, which includes a mounting frame 51 and a first wind speed monitor 53. The mounting frame 51 is a right triangle as a whole, and the mounting frame 51 is installed on the top of the lifting bracket 2 by bolt connection; the first wind speed monitor 53 is installed in the middle of the inner side of the mounting frame 51; a first indicator light 54 is provided on the top of the mounting frame 51; the first indicator light 54 and the first wind speed monitor 53 are both electrically connected to the controller 33.

[0033] Preparation: First, carry the device to the construction site, then install the lifting bracket 2 on the upper part of the floor truss 1, and then vertically install the slide rail 102 on one side of the floor truss 1, with the slide rail 102 being perpendicular to the bottom surface of the lifting bracket 2; Fix the corridor component 200 through the fixing parts, then fix the fixing parts and the hook 44, start the device and power on, the first wind speed monitor 53 and the second wind speed monitor 63 start to monitor the wind speed, pull up the telescopic rod 61 to form a height difference between the two second wind speed monitors 63, after the position of the second wind speed monitor 63 is adjusted, rotate the fastener 62, the fastener 62 moves to the inside of the telescopic rod 61 to press against the inner rod, so as to prevent the second wind speed monitor 63 from being displaced, so that the device can detect wind speed at different heights; drive the hydraulic lifter 31, the hydraulic lifter 31 will start to lift the steel strand 32, in the process of lifting the steel strand 32, the hanger 41 will move up, and while the hanger 41 moves up, the hook 44 will lift the corridor component 200 together, and the scissor-type telescopic frame 82 will bring The dynamic accompanying frame 103 moves up synchronously along the slide rail 102. During the process of the hanger 41 lifting the corridor component 200, the first wind speed monitor 53 and the second wind speed monitor 63 will continue to monitor the wind speed. When the wind speed monitor detects that the wind speed continues to increase significantly and the wind speed transitions from level 4 to level 5, the first wind speed monitor 53 and the second wind speed monitor 63 transmit the signal to the controller 33. The controller 33 controls the first indicator light 54 and the second indicator light 64 to flash continuously, thereby generating an early warning, and the controller 33 drives the hydraulic tensioner 104 to work. The hydraulic tensioner 104 will tighten the second steel wire rope 105 according to the wind speed. As the second steel wire rope 105 is tightened, the influence of the wind speed on the lifting corridor component 200 is reduced, and the shaking amplitude of the corridor component 200 is reduced. When any wind speed monitor detects that the wind intensity reaches or exceeds level 6 (approximately 10.8 to 13.8 meters per second), it is regarded as an extreme weather condition. The controller 33 controls the lifting bracket 2 to stop the lifting operation, and drives the hydraulic tensioner 104 to tighten the second steel wire rope 105 to the maximum extent, so that the corridor component 200 is close to the floor truss 1 to prevent the corridor component 200 from swinging laterally in the air. The controller 33 controls the electromagnetic slider 83 to be energized so that the electromagnetic slider 83 is adsorbed on the magnetic guide rail 81. At this time, the scissor-type telescopic frame 82 cannot be retracted, which can prevent the corridor component 200 from swinging longitudinally in the air, further reducing the risk of shaking. The device can not only monitor the wind speed in real time while lifting the corridor component 200, but also quickly adjust the distance between the corridor component 200 and the floor truss 1 according to the change of wind speed, so as to ensure the safety and stability of the operation under severe weather conditions such as strong winds, and significantly improve the practicality and operation efficiency of the device.

[0034] Embodiment 2: Based on embodiment 1, Figure 5 , Fig. 9 and Fig.10As shown, it also includes an adjusting mechanism 7, which includes a bidirectional threaded rod 71, a sliding member 72, a limiting ring 73 and a nut 74. Three bearing seats are installed in the length direction of the hanger 41. The bidirectional threaded rod 71 is rotatably connected to the hanger 41 through the bearing seats. Both ends of the bidirectional threaded rod 71 are provided with threads, and the threads on both sides are respectively facing in opposite directions. Both sides of the length direction of the hanger 41 are provided with a main sliding groove that passes through the upper and lower parts and a secondary sliding groove that passes from the main sliding groove to the side of the hanger 41. A sliding member 72 is slidably provided in the secondary sliding groove, and one end of the sliding member 72 that penetrates into the main sliding groove is connected to a limiting The ring 73 has a nut 74 at the other end, and the nut 74 is located on the outside of the hanger 41. The first steel wire rope 43 passes through the main slide groove and the limiting ring 73. The nuts 74 on both sides are respectively threadedly connected to the threaded sections on both sides of the two-way threaded rod 71. One end of the two-way threaded rod 71 is hexagonal to adapt to a hexagonal wrench to facilitate the rotation of the threaded rod 71. Auxiliary wheels 75 are rotatably installed on the opposite sides of the two limiting rings 73. The auxiliary wheels 75 are in contact with the first steel wire rope 43. The auxiliary wheels 75 assist the movement of the first steel wire rope 43 to avoid wear caused by direct contact between the first steel wire rope 43 and the limiting ring 73.

[0035] Since the corridor component 200 lifted each time may be different, the width of the corridor component 200 cannot be guaranteed to be consistent. Therefore, before lifting the corridor component 200, it is necessary to adjust the distance between the two hooks 44. The wider the width of the corridor component 200, the larger the distance between the two hooks 44, and vice versa; when adjusting the distance between the two hooks 44, insert the hexagonal end of the two-way threaded rod 71 with a hexagonal wrench, and rotate the two-way threaded rod 71 with the hexagonal wrench. The two-way threaded rod 71 drives the nuts 74 on both sides to move toward or away from each other, and drives the limit ring 73 to move through the sliding member 72. The sliding member 72 moves in the secondary slide groove, and the limit ring 73 moves in the main slide groove. The limit ring 73 drives the first wire rope 43 to move, and the two hooks 44 move accordingly. In this way, the distance between the two hooks 44 can be adjusted, so that the device can adapt to corridor components 200 of different widths, thereby improving the adaptability and utilization rate of the device.

[0036] like Fig.11 As shown, it also includes a winding mechanism 9, which includes two cylindrical gears 91, two worm wheels 92 and a worm 93. The two cylindrical gears 91 are connected to one end of the two rope shafts 42 by key connection. Bearing seats are installed on the upper and lower sides of the middle part of the hanger 41, and a worm 93 is installed between the two bearing seats. The two worm wheels 92 are respectively arranged on both sides of the worm 93 and are located between the two cylindrical gears 91. The worm wheel 92 is rotatably connected to the hanger 41; the worm wheel 92 is meshed with the cylindrical gear 91 and the worm 93 respectively. The lower end of the worm 93 is hexagonal to adapt to a hexagonal wrench to facilitate the rotation of the worm 93. The cylindrical gear 91 is driven by the worm wheel 92 to rotate, so that the rope shaft 42 rotates to wind or lengthen the first wire rope 43.

[0037] After the distance between the two hooks 44 is adjusted, the distance between the hook 44 and the hanger 41 will also change. The first steel wire rope 43 should not be too long or too short. If the first steel wire rope 43 is too long, it will easily cause swinging during lifting, increasing the risk of losing control during the lifting process. If the first steel wire rope 43 is too short, the range of motion of the hook 44 will be limited, making it inconvenient to connect the hook 44 to the corridor component 200. Therefore, in order to ensure the stability and convenience of lifting, the height of the hook 44 can be adjusted; when the position of the hook 44 is too low, it needs to be retracted. When starting, the hexagonal end of the worm 93 can be put on by a hexagonal wrench, and the worm 93 can be driven to rotate by the hexagonal wrench. The worm 93 drives the worm wheels 92 on both sides to rotate, and the two worm wheels 92 drive the two cylindrical gears 91 to rotate, and the cylindrical gear 91 drives the rope shaft 42 to rotate to wind the first wire rope 43. If the position of the hook 44 is too high and needs to be lengthened, the worm 93 can be driven to rotate in the opposite direction by a hexagonal wrench, and the cylindrical gear 91 can be driven to rotate by the worm wheel 92, and the cylindrical gear 91 drives the rope shaft 42 to rotate to lengthen the first wire rope 43.

[0038] A method for using a corridor lifting device with a wind speed dynamic warning function comprises the following steps: S1: Connect the lifting bracket 2 to the embedded connector on the top of the floor truss 1, place the corridor component 200 between the two floor trusses 1, fix the slide rail 102 to the side of the two floor trusses 1 where the corridor component 200 needs to be connected through expansion bolts, the slide rail 102 is parallel to the side of the floor truss 1, and fix the corridor component 200 to the hook 44 through the fixing piece; S2: Start the hydraulic lifter 31 to lift the steel strand 32, the hoisting mechanism 4 will move up, and drive the accompanying frame 103 upward along the slide rail 102 through the stabilizing mechanism 8, thereby lifting the corridor component 200; S3: During the lifting process of the corridor component 200, the first wind speed monitor 53 and the second wind speed monitor 63 continuously monitor the wind speed. When the wind speed is continuously increased, the signal is fed back to the controller 33. After receiving the warning instruction, the controller 33 drives the hydraulic tensioner 104 to tighten the second steel wire rope 105, and applies tension to the hanger 41 through the second steel wire rope 105, so that the corridor component 200 rises steadily; S4: When the corridor component 200 is lifted to the required height, the hydraulic lifter 31 is closed, the corridor component 200 is connected to the steel connector pre-buried in the floor truss 1, the hook 44 is removed, and the lifting bracket 2 and the slide rail 102 are disassembled from the floor truss 1.

[0039] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
