Description

Technical Field

[0001] This utility model belongs to the field of tower crane technology, and in particular relates to a tower crane group operation anti-collision system. Background Technology

[0002] Tower cranes are cranes with a vertical tower and a power-driven rotating jib. They are mainly used for the vertical and horizontal transport of construction materials such as steel bars, timber, concrete, and steel pipes in multi-story building construction, as well as for the installation of building components. Currently, multiple tower cranes are often deployed in large-scale construction projects or complex construction sites in the same area to work together and complete the construction tasks, thereby improving construction efficiency and shortening the construction period. To avoid interference caused by the combined operation of multiple tower cranes, it is necessary to plan and arrange the operation sequence of different tower cranes in advance to avoid collisions between the horizontal booms. Therefore, traditional methods for avoiding collisions of the horizontal booms of tower cranes usually involve reasonable planning of the operation sequence before construction. However, during actual tower crane operation, the horizontal boom cannot detect the distance of surrounding objects in real time, making it impossible for the tower crane operator to predict the movement distance between the horizontal booms in advance, increasing the risk of collisions between tower crane groups. Utility Model Content

[0003] To address the technical problems mentioned in the background section, this utility model provides a tower crane group operation anti-collision system to solve the problem that traditional tower crane groups cannot monitor the movement distance between horizontal booms in real time, resulting in a high risk of horizontal boom collisions.

[0004] To achieve the above objectives, the specific technical solution of the tower crane group operation anti-collision system of this utility model is as follows:

[0005] A collision avoidance system for tower crane groups includes a mounting beam; a horizontal boom is bolted to the lower side of the mounting beam, and a long slot is provided on the upper side of the mounting beam, through which clamping bolts are inserted, with clamping nuts meshing on the outer side of the clamping bolts; it also includes a collision detection device; the collision detection device includes a detection radar, a housing, a shield, a wireless transceiver, a rotating rod, a tilting frame, a driving bevel gear, a driven bevel gear, a swing motor, a controller, a push-pull rod, a slide, a rotating wheel, a slider, a rack plate, a guide rod, and a transmission rod; a driven bevel gear is welded to the outer side of the rotating rod, and the outer side of the rotating rod is rotatably connected to the housing, the top of the housing being securely connected by bolts. The housing has a shield, and a flip frame is firmly welded to the outer side of the rotating rod. A detection radar is bolted to the lower side of the flip frame. A controller and a wireless transceiver are installed inside the housing. A swing motor is bolted to the upper side of the housing. A push-pull rod is mounted on the motor shaft of the swing motor. A guide rod is welded to the inner side of the housing. A slider is slidably connected to the outer side of the guide rod. The slider is welded to the rack plate. A slide frame is bolted to the upper side of the slider. A through groove is provided at the center of the slide frame. A through hole is provided at the center of the lower side of the housing. A transmission rod is rotatably connected to the through hole of the housing. A driving bevel gear is welded to the bottom end of the transmission rod. A driven bevel gear is meshed with the outer side of the driving bevel gear.

[0006] Furthermore, the lower side of the push-pull rod is provided with a cylindrical protrusion, which is embedded in the through groove of the slide.

[0007] Furthermore, the outer side of the wheel is provided with an external tooth structure, and the right tooth surface of the rack plate is engaged with the external tooth structure of the wheel.

[0008] Furthermore, the number of sliders is two sets, and each set of sliders has a through hole on its front side. The guide rod is inserted into the through hole of the slider, and a toothed plate is welded to the right side of the left slider.

[0009] Furthermore, the front and rear sides of the housing are provided with ear plates, and the lower side of each set of ear plates is provided with two sets of through holes. The clamping bolts are inserted into the through holes of the ear plates of the housing, and the through holes of the ear plates of the housing are connected to the bottom end of the long through groove of the mounting beam plate.

[0010] Furthermore, the controller internally includes a power control module, a motor control module, a radar control module, and a wireless signal conversion module. The controller's motor control module is connected to the swing motor via a wire, the controller's radar control module is connected to the detection radar via a wire, and the controller's wireless signal conversion module is connected to the wireless transceiver via a wire.

[0011] The anti-collision system for tower crane group operations of this utility model has the following advantages:

[0012] This invention, on the one hand, drives the swing motor to rotate through the motor control module of the controller. The swing motor then drives the cylindrical protrusion at the bottom of the push-pull rod to push the two sets of sliders connected by the slide bolt to slide back and forth along the guide rod, causing the rack plate to drive the rotating wheel to rotate back and forth. On the other hand, the rotating wheel drives the vertical reversing transmission mechanism composed of the active bevel gear and the driven bevel gear through the transmission rod, causing the rotating rod to drive the tilting frame to rotate back and forth. This realizes the reciprocating tilting scanning and monitoring motion of the detection radar at the bottom of the horizontal boom, enabling the crane operator to obtain the spacing information between multiple sets of tower crane horizontal booms in real time and accurately, effectively reducing the risk of collision between the horizontal booms of the tower crane and providing a strong guarantee for the safe operation of the tower crane.

For example, in the claims, any of the claimed embodiments can be used in any combination.

[0026] like Figures 1-10As shown, this utility model provides a collision avoidance system for tower crane group operations, including a mounting beam 2; a horizontal boom 1 is bolted to the lower side of the mounting beam 2, and a long through groove is provided on the upper side of the mounting beam 2. A clamping bolt 4 is inserted into the long through groove of the mounting beam 2, and a clamping nut 5 is engaged with the outer side of the clamping bolt 4; it also includes a collision avoidance detection device 3; the collision avoidance detection device 3 includes a detection radar 301, a housing 302, a shield 303, and a wireless transceiver. The device comprises: a rotating rod 304, a tilting frame 306, a driving bevel gear 307, a driven bevel gear 308, a swing motor 309, a controller 310, a push-pull rod 311, a slide 312, a rotating wheel 313, a slider 314, a rack plate 315, a guide rod 316, and a transmission rod 317; the driven bevel gear 308 is welded to the outer side of the rotating rod 305, and the outer side of the rotating rod 305 is rotatably connected to the housing 302, the top end of the housing 302 being securely connected by bolts. The housing 302 has a shield 303 and a rotating rod 305. A flip frame 306 is firmly welded to the outer side of the rotating rod 305. A detection radar 301 is bolted to the lower side of the flip frame 306. A controller 310 and a wireless transceiver 304 are installed inside the housing 302. A swing motor 309 is bolted to the upper side of the housing 302. A push-pull rod 311 is installed on the motor shaft of the swing motor 309. A guide rod 316 is welded to the inner side of the housing 302. A slider 314 is slidably connected to the outer side of the guide rod 316. The slider 314 is welded to the rack plate 315. A slide 312 is bolted to the upper side of the slider 314. A through groove is provided at the center of the slide 312. A through hole is provided at the center of the lower side of the housing 302. A transmission rod 317 is rotatably connected to the through hole of the housing 302. A drive bevel gear 307 is welded to the bottom end of the transmission rod 317. A driven bevel gear 308 is meshed with the outer side of the drive bevel gear 307.

[0027] In this embodiment, the lower side of the push-pull rod 311 is provided with a cylindrical protrusion. The cylindrical protrusion of the push-pull rod 311 is embedded in the through groove of the slide 312. During the process of the swing motor 309 driving the push-pull rod 311 to rotate, the cylindrical protrusion of the push-pull rod 311 pushes the groove wall of the long through groove of the slide 312, causing the slide 312 to drive the two sets of bolt-connected sliders 314 to move back and forth along the guide rod 316, so that the rack plate 315 drives the rotating wheel 313 to rotate back and forth.

[0028] In this embodiment, the outer side of the rotating wheel 313 is provided with an external tooth structure. The right tooth surface of the rack plate 315 is meshed with the external tooth structure of the rotating wheel 313. During the reciprocating movement of the slider 314 along the guide rod 316, the rotating wheel 313 is driven to rotate. The rotating wheel 313 drives the active bevel gear 307 and the driven bevel gear 308 to form a vertical reversing transmission structure through the transmission rod 317. This allows the rotating rod 305 to drive the flipping frame 306 to rotate 90 degrees left and right, thereby increasing the illumination and scanning detection area of ​​the detection radar 301.

[0029] In this embodiment, there are two sets of sliders 314. Each set of sliders 314 has a through hole on its front side. A guide rod 316 is inserted into the through hole of the slider 314. A rack plate 315 is welded to the right side of the left slider 314. The two sets of guide rods 316 support the two sets of sliders 314 to move back and forth in a directional manner, so that the rack plate 315 welded to the left slider 314 engages with the external tooth structure of the rotating wheel 313, ensuring that the rotating wheel 313 is stably engaged and rolled on the rack plate 315.

[0030] In this embodiment, the front and rear sides of the housing 302 are provided with ear plates. The lower side of each ear plate is provided with two sets of through holes. The clamping bolts 4 are inserted into the through holes of the ear plates of the housing 302. The through holes of the ear plates of the housing 302 are connected to the bottom end of the long through groove of the mounting beam plate 2. The housing 302 can be installed along any part of the long through groove of the mounting beam plate 2 by means of the clamping bolts 4 and clamping nuts 5, which improves the flexibility of the anti-collision detection device 3 in the installation distribution position of the horizontal boom 1.

[0031] In this embodiment, the controller 310 is internally equipped with a power control module, a motor control module, a radar control module, and a wireless signal conversion module. The motor control module of the controller 310 is connected to the swing motor 309 via a wire, the radar control module of the controller 310 is connected to the detection radar 301 via a wire, and the wireless signal conversion module of the controller 310 is connected to the wireless transceiver 304 via a wire. This allows the distance data measured by the detection radar 301 to be transmitted wirelessly to the computer in the tower crane cab for early warning monitoring. This enables the tower crane operator to quickly know the distance between the horizontal booms 1, facilitating collision avoidance and reducing the collision risk of the horizontal booms 1.

[0032] The specific usage and function of this embodiment are as follows:

[0033] When performing anti-collision detection on the horizontal boom 1, the power supply equipment of the tower crane supplies power to the power control module of the controller 310 via a wire. This causes the motor control module of the controller 310 to start the swing motor 309 via the wire. The swing motor 309 drives the push-pull rod 311 to rotate. At this time, the cylindrical protrusion on the lower side of the push-pull rod 311 pushes against the groove wall of the slide 312, causing the slide 312 to drive the two sets of sliders 314 to move back and forth along the guide rod 316. Since the external tooth structure of the rotating wheel 313 is meshed with the tooth surface of the rack plate 315, the rack plate 315 welded to the right side of the left slider 314 drives the rotating wheel 313 to rotate forward and backward. The rotating wheel 313 drives the active bevel gear 307 welded to the transmission rod 317 to rotate synchronously. The active bevel gear 307 drives the driven bevel gear 308, which is meshed with its outer side, to rotate synchronously. The driven bevel gear 308 drives the rotating rod 305 to rotate reciprocally. The rotating rod 305, in turn, drives the detection radar 301, which is bolted to the tilting frame 306, to rotate left and right around the central axis of the rotating rod 305 in a range of 180 degrees. The radar control module of the controller 310 controls the detection radar 301 to emit radar waves through wires. The detection radar 301 detects the distance of surrounding objects and sends the detected data to the wireless signal conversion module of the controller 310 through wires. The wireless signal conversion module of the controller 310 then transmits the data wirelessly to the wireless transceiver 304 through wires, so that the control computer of the tower crane operator can receive the detected distance data in real time.

[0034] All the above components are installed, connected, or set up using common mechanical methods, such as welding, threaded connections, and screw connections. Furthermore, the specific structure, model, and coefficient specifications of all components are based on their own technologies; any method that achieves the desired beneficial effect can be implemented. The detection radar 301, wireless transceiver 304, swing motor 309, and controller 310 mentioned above are all common commercially available components. Upon purchase and use, simply follow the instruction manual provided with the device to connect them for operation; therefore, further details are omitted here.

[0035] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
