Description

Technical Field

[0001] The present application relates to the field of tower crane safety technology, and in particular to a real-time monitoring device for a tower crane environment. Background Art

[0002] In the field of modern construction engineering, tower cranes, as a key large-scale mechanical equipment, play an irreplaceable role. They are usually composed of metal structures, working mechanisms, electrical systems and safety devices. The metal structure covers the tower body, lifting arm, balance arm and tower cap, etc., providing a solid support and framework for the tower crane; the working mechanism includes lifting, luffing, slewing and walking mechanisms, which respectively undertake the functions of lifting and lowering heavy objects, extending and retracting the lifting arm, rotating the tower arm and moving the tower crane; the electrical system is responsible for providing power and control for each mechanism; safety devices such as lifting weight limiter, lifting torque limiter and travel limiter ensure the stable operation of the tower crane within a safe range. With its large lifting height and working radius, as well as efficient and simple operation characteristics, the tower crane can lift various building materials such as steel bars, concrete, and formwork to the designated location. It is widely used in various construction projects such as high-rise buildings, bridge construction, large factories, etc., which greatly improves the construction efficiency and reduces the intensity of manual labor;

[0003] However, despite strict safety standards for tower crane construction, tower crane overturning accidents still occur from time to time, causing a certain number of casualties every year. After analysis, the main cause of the accident is the poor level of information management and control of the tower crane, incomplete monitoring data, and loopholes in the risk warning mechanism. Especially when the tower crane is subjected to complex loads, if the lateral connection of the tower crane is not firm or not connected, it is very easy to cause the tower crane frame to tilt. Once the tilt angle is too large, the tower crane frame itself is difficult to recover, and it may even cause the entire tower crane to overturn.

[0004] At present, in the existing technology, for monitoring tower cranes, inclination sensors are generally installed on the tower crane. Although such sensors can perform monitoring functions to a certain extent, they have obvious limitations. On the one hand, they can only be fixed at a specific position of the tower crane. If deformation occurs in other positions of the tower crane, sensors not in this area cannot be monitored in time. For example, when the tower crane body is deformed under heavy pressure, even if the tower crane has not yet tilted significantly, as the deformation continues to develop, the tower crane is very likely to collapse suddenly, and the existing technology makes it difficult to monitor the deformation of the tower crane in time. On the other hand, when the deformation point of the tower crane is located at the top of the sensor, since no deformation or tilt occurs at the position of the sensor, effective monitoring cannot be performed. In summary, the existing tower crane monitoring device has certain defects and shortcomings, and it is difficult to meet the needs of comprehensive and accurate monitoring of the safety status of the tower crane in actual projects, and it is urgently needed to be improved and designed.

[0017] In summary, this application includes the following beneficial technical effects:

[0018] 1. The device is provided with a docking mechanism. When in use, the height of the spliced ​​guide rails is selected according to the specific height of the tower crane, and multiple guide rails are spliced ​​so that the plug-in plate is inserted between the clamping plate and the inner side of the fixed arm. Then the hand-tightening installation screw is twisted to insert it into the clamping hole. The hand-tightening installation screw and the clamping hole are mutually limited to achieve auxiliary docking installation of the guide rails. This docking installation method enables the device to flexibly dock different groups of guide rails according to specific installation requirements. When the guide rails are assembled and installed, the limit holes on the guide rails are used to cooperate with the bolts to install the guide rails to the tower crane. The limit holes are set as countersunk holes. After installation, the nuts of the bolts can be hidden inside the countersunk holes to ensure that after the guide rails are installed, the sliders can slide stably, which provides convenience for the stable installation and use of the device.

[0019] 2. When the detection mechanism of this device is in operation, the first motor is started first, and the gear at the output end of the first motor meshes with the rack. The operation of the motor drives the gear to rotate, and the meshing transmission is used to assist in driving the slider to slide in the guide rail. Through the coordination of the gear and the guide rail, the stable regulation of the slider movement is achieved. The slider slides in the guide rail, prompting the entire monitoring mechanism to move flexibly along the guide rail direction, so as to accurately detect different heights of the tower crane. During the detection, the gyroscope sensor of the first detection component plays a key role. When the slider rises to the tilted position of the tower crane, the gyroscope sensor immediately detects. Once the tilt exceeds the safe range, the controller in the chassis controls the remote alarm to warn, realizing mobile detection at any time, effectively improving the monitoring effect of the tilt of the tower crane at different heights, and ensuring the safety of the tower crane operation;

[0020] 3. While the first motor drives the slider to slide, the second detection component starts working and drives the electric push rod to run. The push rod pushes the base plate to move toward the tower crane, so that the monitoring guide roller on the base plate fits the outer surface of the tower crane. As the slider slides, the monitoring guide roller rolls on the surface of the frame. If the tower crane is deformed, the surface becomes twisted or bent and uneven, and the rolling of the monitoring guide roller will fluctuate. The telescopic spring then assists in telescoping to ensure stable contact of the monitoring guide roller. When the guide roller rolls to the twisted part, it is squeezed and touches the telescopic spring, compressing or stretching it, thereby pulling the pressure sensor to change the detection pressure fluctuation. The degree of deformation of the tower crane can be judged based on the amplitude of the pressure fluctuation. The second motor is started to drive the screw rod to rotate, driving the movable block to slide in the rail frame, changing the position of the electric push rod and the monitoring guide roller, expanding the monitoring area, and improving the monitoring accuracy.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-8 This application is described in further detail.

[0031] The present application embodiment discloses a real-time monitoring device for a tower crane environment. Figure 1-8 As shown, it includes a guide rail 1, which is provided in a plurality of pieces. A docking mechanism 2 is provided at the end of the guide rail 1. A monitoring mechanism 5 is movably installed inside one of the guide rails 1. Limiting holes 4 are arranged linearly at equal intervals on the inner side of the guide rail 1. The limiting holes 4 are provided as countersunk mounting holes.

[0032] The monitoring mechanism 5 includes a slider 51 and a rack 52. The slider 51 is slidably connected to the inside of the guide rail 1. The rack 52 is fixedly connected to a fixed bar 3 on one side close to the guide rail 1. The fixed bar 3 is fixedly connected to one side of the guide rail 1. A power component 53 is fixedly installed on the outside of the slider 51. The power component 53 and the rack 52 are meshed and connected. A first monitoring component 56 is fixedly installed on the outside of the power component 53. A second monitoring component 59 is fixedly installed on one side of the first monitoring component 56. A support rod 54 is installed on the top of the power component 53. A shielding plate 55 is fixedly connected to the top of the support rod 54. The device adopts multiple guide rails 1 and is spliced ​​by a docking mechanism 2 at the end. The length can be adjusted according to actual needs, and the linear arrangement of the inner side of the guide rail 1 is utilized. The countersunk mounting hole-shaped limit hole 4 can be used with bolts to install the guide rail 1 on the tower crane. During monitoring, the power component 53 is installed on the outside of the slider 51, which engages with the rack 52 fixed on one side of the guide rail 1. The power component 53 is started, driving the slider 51 to slide inside the guide rail 1, and then driving the entire monitoring mechanism 5 to move along the guide rail 1. During the movement, the baffle 55 on the top support rod 54 of the power component 53 can prevent debris from interfering with the monitoring. At the same time, the first monitoring component 56 monitors key data such as the inclination angle of the tower crane, and the second monitoring component 59 focuses on detecting whether the tower crane frame is deformed or not. Through the coordinated work of the two, real-time monitoring of the tower crane environment is realized, providing comprehensive data support for the safe operation of the tower crane.

[0033] Please refer to Figure 4-Figure 6The power assembly 53 includes a mounting sleeve 531, which is fixedly mounted on the outer side of the slider 51. A first motor 532 is fixedly connected inside the mounting sleeve 531. A gear 533 is fixedly connected to the output end of the first motor 532. The gear 533 is meshed with the rack 52. A connecting rod 534 is fixedly connected to the side of the first motor 532 close to the gear 533 at equal intervals. A protective shell 535 is fixedly connected to the outer side of the connecting rod 534. The protective shell 535 covers the outer side of the gear 533. The cross-sectional shape of the internal cavity of the guide rail 1 is convex, and the shape of the slider 51 is also convex. Wear-resistant gaskets are fixedly connected to the outer surface of the slider 51 and the inner wall of the guide rail 1. A photovoltaic panel 57 is fixedly mounted on the top of the baffle plate 55. A chassis 58 is fixedly connected to the bottom of the baffle plate 55. A controller and a battery are arranged inside the chassis 58. The operation of the power assembly 53 can ensure the stable operation of the real-time monitoring device for the tower crane environment. When the monitoring device is started, the first A motor 532 starts to work, and the gear 533 at the output end of the first motor 532 meshes with the rack 52 fixed on one side of the guide rail 1. As the first motor 532 runs, the gear 533 is driven to rotate, and the meshing transmission of the gear 533 and the rack 52 is used to drive the slider 51 to slide inside the guide rail 1. Since the internal cavity of the guide rail 1 and the slider 51 are both convex, this special structure can prevent the slider 51 from deflecting or falling off during the sliding process. At the same time, the wear-resistant gaskets fixed on the outer surfaces of both can effectively reduce friction and extend the service life of the equipment. The connecting rod 534 installed on the side of the first motor 532 close to the gear 533 has a protective shell 535 connected to the outside that covers the outside of the gear 533 to protect the gear 533 from being disturbed by external debris. The photovoltaic panel 57 on the top of the baffle plate 55 can convert solar energy into electrical energy, which is stored in the battery in the chassis 58 to power the device. The controller in the chassis 58 is responsible for controlling the operation of the entire device, coordinating the work of various components, and ensuring the smooth progress of the monitoring work.

[0034] Please refer to Figure 1-Figure 3The docking mechanism 2 includes a plug-in plate 21 and a clamping plate 22. The plug-in plate 21 is fixedly connected to both sides of one end of the guide rail 1, and the clamping plate 22 is fixedly connected to both sides of the other end of the guide rail 1. A fixed arm 23 is fixedly installed on the outer side of the clamping plate 22. The outer end of the fixed arm 23 is threadedly connected with a hand-tightening installation screw 24. The end of the hand-tightening installation screw 24 passes through the fixed arm 23. The plug-in plate 21 on one guide rail 1 is inserted between the clamping plate 22 on the other guide rail 1 and the inner side of the fixed arm 23. A clamping hole 25 is opened on the outer side of the plug-in plate 21. The end of the hand-tightening installation screw 24 passes through the clamping plate 22 and is inserted into the inside of the clamping hole 25. When the guide rail 1 needs to be connected, one guide rail 1 is connected. The plug-in plates 21 fixed on both sides of one end of the rail 1 are aligned and inserted between the clamping plates 22 and the inner sides of the fixed arms 23 on both sides of the other end of the other guide rail 1. At this time, after the insertion, the hand-tightened installation screw 24 threadedly connected at the outer end of the fixed arm 23 is rotated to make its end pass through the clamping plate 22 and then inserted into the clamping hole 25 opened on the outer side of the plug-in plate 21. The hand-tightened installation screw 24 and the clamping hole 25 cooperate with each other to form a limit, so that the two guide rails 1 are firmly connected together. In this way, multiple guide rails 1 can be flexibly spliced ​​into the required length according to the actual application scenario, which is convenient for the subsequent monitoring mechanism 5 to move on the guide rail 1 to achieve effective monitoring of different positions of the tower crane.

[0035] Please refer to Figure 3-Figure 8The first monitoring component 56 includes a mounting frame 561, which is fixedly mounted on the outside of the mounting sleeve 531. A base frame 562 is fixedly mounted on the outside of the mounting frame 561. A gyroscope sensor 563 is fixedly mounted on the middle of the outside of the base frame 562. A remote alarm 564 is fixedly connected to the top of the base frame 562. The second monitoring component 59 includes a rail frame 591, which is fixedly mounted on the inside of the mounting frame 561. A screw rod 592 is rotatably connected to the inside of the rail frame 591. A movable block 593 is threadedly connected to the outer surface of the screw rod 592. The movable block 593 is slidably connected to the inside of the rail frame 591. A bearing group 594 is fixedly mounted on one side of the movable block 593. A monitor 595 is installed on the end of the bearing group 594. The rail frame 59 1 is fixedly connected to the outer side of the rail frame 591 with a second motor 596, and the output end of the second motor 596 is fixedly connected to the end of the screw rod 592. The bearing group 594 includes a side plate 5941, and the side plate 5941 is fixedly connected to one side of the movable block 593. The outer ends of the side plate 5941 are fixedly installed with fixed plates 5942, and the inner side of the fixed plate 5942 is fixedly installed with an electric push rod 5943. The output end of the electric push rod 5943 on the side close to the rail frame 591 passes through the fixed plate 5942 and is connected to the monitor 595. The monitor 595 includes a bottom plate 5951, and the bottom plate 5951 is fixedly installed on the output end of the electric push rod 5943. A fixed seat 5952 is fixedly connected to the side of the bottom plate 5951 away from the electric push rod 5943 in a linear arrangement with equal intervals. A pressure sensor 5953 is fixedly installed on one side of the fixed seat 5952 away from the bottom plate 5951, and a frame 5954 is fixedly installed on the end of the pressure sensor 5953. Telescopic springs 5955 are fixedly connected at both ends of the frame 5954. A concave seat 5956 is fixedly connected to the outside of the telescopic spring 5955. A monitoring guide roller 5957 is rotatably connected to the inside of the concave seat 5956. Supporting rods 5958 are fixedly connected at both ends of the concave seat 5956 close to the frame 5954. The ends of the supporting rods 5958 penetrate the frame 5954. The supporting rods 5958 and the frame 5954 are slidably connected to each other. When the monitoring device is running, the first monitoring component 56 and the second monitoring component 59 work together to realize comprehensive monitoring of the operating status of the tower crane. In the first monitoring component 56, a base frame 562 is installed on the mounting frame 561 outside the mounting sleeve 531, and a gyroscope sensor 563 in the middle of the outer side monitors the tilt angle of the tower crane in real time. Once it is detected that the tilt angle exceeds the safe range, the remote alarm 564 on the top of the base frame 562 is immediately activated to alert relevant personnel. In the second monitoring component 59, a rail frame 591 is fixed inside the mounting frame 561, and the second motor 596 outside the rail frame 591 is started. The output end of the motor drives the screw rod 592 to rotate, and the movable block 593 threadedly connected to the outer surface of the screw rod 592 slides in the rail frame 591, and the bearing group 594 on one side of the movable block 593 moves accordingly. The monitor 595 at the end of the bearing group 594 monitors the deformation of the tower crane frame.The side plate 5941 of the bearing group 594 is fixed on the movable block 593. The electric push rods 5943 in the fixed plates 5942 at both ends of the outer side of the side plate 5941 have their output ends connected to the bottom plate 5951 of the monitor 595. The electric push rods 5943 are started to push the bottom plate 5951 close to the tower crane frame, so that the monitoring guide rollers 5957 on the bottom plate 5951 contact the surface of the tower crane frame. When the monitoring guide rollers 5957 roll on the surface of the tower crane frame, if the tower crane frame is deformed and the surface is uneven, the monitoring guide rollers 5957 will fluctuate, squeezing the telescopic springs 5955, driving the concave seat 5956 to move, and the supporting rods 5958 slide in the frame 5954 to assist in supporting and maintaining the stability of the concave frame. The pressure sensor 5953 detects the pressure change and determines the degree of deformation of the tower crane frame according to the pressure change amplitude, thereby realizing all-round monitoring of the tower crane.

[0036] The implementation principle of a real-time monitoring device for tower crane environment in an embodiment of the present application is as follows: by setting a docking mechanism 2, the height of the spliced ​​guide rail 1 can be selected according to the specific height of the tower crane during use of the device. At this time, multiple guide rails 1 are spliced ​​together, and the plug-in plate 21 is inserted between the inner side of the clamping plate 22 and the fixed arm 23. At this time, the hand-tightening installation screw 24 can be twisted and inserted into the inside of the clamping hole 25. The hand-tightening installation screw 24 and the clamping hole 25 limit each other to assist in docking and installing the guide rail 1. Through this docking and installation method, the device as a whole can be flexibly docked with different groups of guide rails 1 according to specific installation requirements. During the combined installation of the guide rails 1, the guide rails 1 can be installed on the tower crane through the limiting holes 4 on the guide rails 1 and the bolts. During the installation, the limiting holes 4 are set as countersunk holes, and the nuts of the bolts can be hidden on the inner side of the countersunk holes, so that after the guide rails 1 are installed, the stable sliding of the slider 51 can be ensured, which facilitates the stable installation and use of the device.

[0037] By setting up the detection mechanism, during the application of the device, the first motor 532 can be started to operate. A gear 533 is installed at the output end of the first motor 532. The gear 533 and the rack 52 are meshed and connected. As the first motor 532 drives the gear 533 to rotate, the gear 533 and the rack 52 are meshed and transmitted. The first motor 532 can drive the gear 533 to assist in driving the slider 51 to slide inside the guide rail 1. The driving gear 533 cooperates with the guide rail 1 to operate, and then the slider 51 can be adjusted to move stably inside the guide rail 1. At this time, by adjusting the slider 51 to slide inside the guide rail 1, the entire monitoring mechanism can be activated. 5 can be flexibly displaced along the extension direction of the guide rail 1, so that the device can accurately detect different heights of the tower crane. During the detection period, the gyro sensor 563 in the first detection component can be used for detection. As the slider 51 rises to adjust the height, when it rises to a position where the tower crane is tilted, the gyro sensor 563 can be used for detection. When the tilt exceeds the safe range, the controller inside the chassis 58 can control the remote alarm 564 to issue an early warning, so that the device can be moved at any time during the detection period, and can better detect the tilt of the tower crane at different heights, which can further improve its monitoring effect and ensure the safety of the tower crane.

[0038] By setting up the second detection group component, during use, when the first motor 532 drives the slider 51 to slide and move, it can drive the electric push rod 5943 to operate. The operation of the electric push rod 5943 can push the bottom plate 5951 to move toward the tower crane on the side of the guide rail 1. At this time, the monitoring guide roller 5957 on the bottom plate 5951 can be driven to fit the outer surface of the tower crane. At this time, as the first motor 532 drives the slider 51 to slide inside the guide rail 1, the monitoring guide roller 5957 can be urged to fit the outer surface of the tower crane and roll. During the rolling of the monitoring guide roller 5957 on the tower crane, if the tower crane is deformed, it will avoid micro-twisting or bending. At this time, the outer surface of the tower crane will inevitably be uneven. At this time, the monitoring guide roller 5957 will inevitably fluctuate when it rolls on the tower crane. In this process, the telescopic spring 5955 can be used to assist in telescoping, so that the monitoring guide roller 5957 can stably contact the tower crane. When the monitoring guide roller 5957 rolls to the twisted part, The twisted deformation of the tower crane will inevitably squeeze the monitoring guide roller 5957. When the monitoring guide roller 5957 is squeezed, the telescopic spring 5955 will be triggered to compress or stretch it. At this time, the pressure sensor 5953 will inevitably be pulled. When the pressure sensor 5953 is triggered, the pressure fluctuation detected by the pressure sensor 5953 will be changed. During use, the deformation degree of the tower crane can be judged according to the fluctuation amplitude of the data detected by the pressure sensor 5953. It can be seen that the device can monitor the condition of the tower crane more accurately during use. In the process of monitoring, the second motor 596 can be started to drive the screw rod 592 to rotate. The rotation of the screw rod 592 can drive the movable block 593 to slide inside the rail frame 591.
