Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a tower crane anti-collision device based on BIM. Background Art

[0002] With the increasing demand for efficiency and safety in the construction industry, Building Information Modeling (BIM) technology has been gradually applied to construction management. It constructs a three-dimensional model of the construction project through digital means, integrates the information of the entire life cycle of the building, and provides strong technical support for tower crane management. Through the application of BIM technology, full-dimensional visual management of the tower crane construction process can be achieved, which greatly improves the efficiency and accuracy of construction management. However, in the process of building construction, when multiple towers are working at the same time, the safe distance between tower cranes is difficult to effectively control. Once a collision occurs, it will not only cause construction delays and increase project costs, but also may pose safety risks and pose a potential threat to the life safety of construction workers. Therefore, a tower crane anti-collision device based on BIM is proposed to improve the safety of tower cranes in a multi-tower environment and reduce the risk of collision. In the process of realizing the present invention, the inventors found that at least the following problems exist in the prior art that have not been solved: the existing anti-collision device for tower cranes uses power-off to stop the operation of the tower crane. When the power is off, the tower crane will continue to move due to the influence of moving inertia, and the tower crane that is about to collide cannot be locked in time, causing the boom of the tower crane to collide with surrounding obstacles under the action of inertia, thereby reducing the safety of construction. Summary of the invention

[0003] The purpose of the present invention is to solve the shortcomings existing in the prior art, such as: the existing tower crane anti-collision device adopts the power-off method to stop the operation of the tower crane, and the tower crane will continue to move due to the influence of moving inertia when the power is off, and the tower crane that is about to collide cannot be locked in time, causing the boom of the tower crane to collide with surrounding obstacles under the action of inertia, thereby reducing the safety of construction.

The clamping and locking disk locks the rotating seat by the cooperation of the second gear assembly and the face gear ring, and the purpose of locking the tower crane arm is achieved by locking the position of the rotating seat, thereby realizing that the clamping and locking mechanism locks the position of the tower crane arm while the buffer mechanism deploys to buffer the collision force, so that the position of the tower crane arm remains stable when subjected to the collision force.

Once a potential collision risk is detected, an audible and visual alarm can be quickly issued, the driving mechanism can be controlled to operate, and the power supply of the driving motor can be cut off.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] See also Figure 1-Figure 10 The present invention proposes a BIM-based tower crane anti-collision device, comprising a tower crane top seat 1, a tower crane arm 4, a buffer mechanism 6 and a clamping and locking mechanism 7, and also comprises a rotating seat 2 installed on the outside of the tower crane top seat 1 through a ball rotation, and a tower crane arm 4 fixedly installed on one side of the rotating seat 2, the top and bottom of the rotating seat 2 are fixedly installed with a face gear ring 201, and the front of the rotating seat 2 is fixedly installed with a BIM control box 3; A protective seat 5 is fixedly installed on one side of the bottom of the tower crane arm 4 close to the rotating seat 2, and a clamping and locking disk 503 extending to the inside of the tower crane arm 4 is rotatably installed inside the protective seat 5. A second gear assembly 504 is installed through one side of the inside of the protective seat 5, and one end of the second gear assembly 504 located inside the protective seat 5 is meshed and connected with the bottom end of the clamping and locking disk 503, and the other end of the second gear assembly 504 is meshed and connected with the face gear ring 201 at the bottom of the rotating seat 2; A driving mechanism 8 is fixedly installed at one end of the tower boom 4, and the driving mechanism 8 is connected with the buffer mechanism 6 and the clamping and locking mechanism 7 by transmission. The driving mechanism 8 drives the clamping and locking mechanism 7 and the buffer mechanism 6 to operate synchronously, so that the driving mechanism 8 drives the buffer mechanism 6 to extend out of the tower boom 4, and the clamping and locking mechanism 7 synchronously drives the clamping and locking disk 503 to clamp and lock it. The clamping and locking disk 503 uses the cooperation of the second gear assembly 504 and the face gear ring 201 to lock the rotating seat 2, and the purpose of locking the tower boom 4 is achieved by locking the position of the rotating seat 2, so that the clamping and locking mechanism 7 locks the position of the tower boom 4 while the buffer mechanism 6 is deployed to buffer the collision force, so that the position of the tower boom 4 remains stable when subjected to the collision force. When the rotating seat 2 rotates, the meshing second gear assembly 504 is driven to rotate through the face gear ring 201 at the bottom, and the rotating second gear assembly 504 drives the meshing locking plate 503 to rotate. Therefore, the locking plate 503 rotates synchronously with the rotating seat 2. When the locking mechanism 7 and the buffer mechanism 6 are driven by the driving mechanism 8 to operate synchronously, the locking mechanism 7 slowly performs friction locking on the locking plate 503, so that the locking plate 503 slowly stops rotating until it is locked. Since the locking plate 503 is connected to the face gear ring 201 through the second gear assembly 504, when the locking plate 503 is slowly locked, the tower crane arm 4 on one side of the rotating seat 2 is slowly stopped, so as to avoid the tower crane arm 4 from being swung and collided and dropped under the action of inertia due to the emergency braking inertia, that is, to prevent the tower crane arm from colliding with surrounding obstacles, and effectively prevent the occurrence of safety accidents. While the locking mechanism 7 locks the tower crane arm 4, the driving mechanism 8 drives the two buffer mechanisms 6 to move relative to each other. The two relatively moving buffer mechanisms 6 extend out of the tower crane arm 4 through the storage port 402. The extended buffer mechanisms 6 can bear the collision force. The elastic force of the buffer mechanisms 6 can buffer the collision force, thereby reducing the collision force applied to the tower crane arm 4. The locked tower crane arm 4 can remain stable when the buffer mechanisms 6 are subjected to the impact force, thereby preventing the tower crane arm 4 from rotating due to the impact force.

[0019] like Figure 5 , Fig. 9 , Fig.10As shown, receiving openings 402 are provided on both sides of the tower crane arm 4, and two opposite buffer mechanisms 6 are movably installed inside the tower crane arm 4 through the receiving openings 402, and the buffer mechanism 6 includes a buffer seat 601, a mounting seat 602, a first rack plate 603, a second rack plate 604 and an elastic buffer 605, and the elastic buffer 605 is equidistantly installed inside the mounting seat 602, the buffer seat 601 is movably sleeved on the outer side of the mounting seat 602, and the inner wall of the buffer seat 601 is fixedly connected to one end of the elastic buffer 605, a second rack plate 604 is fixedly installed on one side of the mounting seat 602, and a second rack plate 604 is fixedly installed on the bottom of one side of the second rack plate 604; The mounting seat 602 is driven to move horizontally by the two first rack plates 603 moving relatively far away from each other, and the mounting seat 602 moving horizontally drives the buffer seat 601 to move out of the tower crane arm 4 through the storage port 402. The elastic force of the elastic buffer member 605 can be used to elastically move the buffer seat 601 when it is hit, thereby reducing the impact force on the tower crane arm 4. When the first rack plate 603 moves, the second rack plate 604 is driven to move, and the moving second rack plate 604 drives the screw rod 706 to rotate through the meshing transmission gear 707. The two first rack plates 603 that move relatively close to each other drive the buffer seat 601 to move horizontally inward to the inside of the tower crane arm 4 through the mounting seat 602, so as to store the buffer mechanism 6.

[0020] like Figure 7 , Figure 8 As shown, the clamping and locking mechanism 7 is fixedly installed on one side of the tower crane arm 4 near the clamping and locking plate 503, and the clamping and locking mechanism 7 includes a slide rail frame 701 fixedly installed on the inside of the tower crane arm 4, a slider 702 is movably installed inside the slide rail frame 701, and clamping shafts 703 are installed on both sides of the top of the slider 702 through shaft bolts, and a connecting rod 704 is fixedly installed on one side of the slider 702 through a pull rod passing through the slide rail frame 701, and a threaded sleeve 705 is fixedly installed on one end of the connecting rod 704, and a screw rod 706 extending to the inside of the connecting rod 704 is installed through the inside of the screw sleeve 705, and a transmission gear 707 is fixedly installed on one end of the screw rod 706, and the top of the transmission gear 707 is meshed and connected with the bottom of the second rack plate 604; The first rack plate 603 moves while the second rack plate 604 moves synchronously. The moving second rack plate 604 cooperates with the meshing transmission gear 707 to drive the screw rod 706 to rotate forward. The forward rotating screw rod 706 drives the connecting rod 704 to move horizontally to the right through the thread sleeve 705. The connecting rod 704 moving horizontally to the right drives the slider 702 to move through the pull rod. The moving slider 702 drives the two clamping shafts 703 to move relatively inwards through the cooperation of the guide rod 708 and the guide groove 7031 to frictionally lock the clamping locking disk 503. When the first rack plate 603 contracts and moves, the transmission gear 707 is driven to rotate in the opposite direction through the second rack plate 604 which moves synchronously. The transmission gear 707 which rotates in the opposite direction drives the connecting rod 704 to move horizontally to the left through the screw rod 706 and the screw sleeve 705. The connecting rod 704 which moves horizontally to the left drives the slider 702 to move to the left through the pull rod. The slider 702 which moves to the left drives the two clamping shafts 703 to move relatively outwards and away from the two sides of the clamping locking disk 503 through the cooperation of the guide rod 708 and the guide groove 7031, thereby unlocking the clamping locking disk 503.

[0021] like Figure 7 , Figure 8 As shown, a guide groove 7031 is provided inside the clamping shaft 703, a rubber pad 7032 is fixedly installed on the inner side of the clamping shaft 703, and guide rods 708 are fixedly installed on both sides of the top of the slide rail frame 701, and the guide rods 708 extend to the guide groove 7031 inside the clamping shaft 703, and the guide rods are movably connected to the clamping shaft 703 through the guide groove 7031; Among them, the guide groove 7031 cooperates with the clamping shaft 703 to limit the moving direction of the clamping shaft 703, so that the two clamping shafts 703 can be clamped and locked inwardly, and expanded outwardly to be unlocked, and the rubber pad 7032 has good friction, which can increase the friction between the clamping shaft 703 and the clamping locking plate 503.

[0022] like Fig. 9 , Fig.10 As shown, the driving mechanism 8 includes a driving gear 801 installed inside the tower crane arm 4 through a turntable, and both sides of the driving gear 801 are respectively meshed and connected to the first rack plate 603, a driving gear 802 is fixedly installed on the top of the driving gear 801, and one side of the driving gear 802 is meshed and connected to a rack rod 803, and one end of the rack rod 803 is fixedly installed with a hydraulic rod 804, and the hydraulic rod 804 is fixedly installed on the inner wall of the tower crane arm 4; The hydraulic rod 804 drives the rack rod 803 to move horizontally to the left, and the driving gear 801 is driven to rotate positively through the meshing active gear 802. The positively rotating driving gear 801 drives the two first rack plates 603 meshingly connected on both sides to move relatively away from each other. The two first rack plates 603 moving relatively away from each other drive the buffer seat 601 to move out of the tower boom 4 through the mounting seat 602. The hydraulic rod 804 drives the rack rod 803 to move horizontally to the right, and the driving gear 802 connected in meshing drives the driving gear 801 to rotate in the opposite direction. The driving gear 801 rotating in the opposite direction drives the two first rack plates 603 connected in meshing on both sides to move relatively close to each other. The two first rack plates 603 moving relatively close to each other drive the buffer seat 601 to move to the inside of the tower boom 4 through the mounting seat 602. The hydraulic rod 804 drives the rack rod 803 to move horizontally to the left and right, thereby controlling the buffer mechanism 6 to perform expansion and storage movement.

[0023] like Figure 1-Figure 5 As shown, a camera 501 is fixedly installed at the bottom of the protection seat 5, and a radar microwave sensor 502 is fixedly installed on one side of the outside of the protection seat 5, and the camera 501 and the radar microwave sensor 502 are both electrically connected to the BIM control box 3 through wires; Among them, the radar microwave sensor 502 is composed of a signal processor, a microwave oscillator and a microwave antenna. The microwave oscillator in the radar microwave sensor 502 is responsible for generating microwave signals, and the signals are transmitted through the antenna. When the microwaves encounter an object, they are reflected. The reflected microwave signals are received by the receiving antenna and converted into electrical signals. The signal processor analyzes the electrical signals to identify the information of the target object, such as distance, speed, size and shape, and transmits the identified electrical signals to the BIM control box 3 through wires. At the same time, the camera 501 monitors the area below the tower crane arm 4 in real time to realize intelligent tracking and real-time shooting of the hook position, and transmits the shooting signals to the BIM control box 3. The electric signal is sent to the BIM control box 3, and the full-dimensional visual management of the tower crane construction process is realized through the BIM control box 3; and the BIM control box 3 analyzes the received electrical signal, and the BIM control box 3 performs corresponding processing according to the analysis result. When the BIM control box 3 analyzes that the tower crane is in danger of collision, the BIM control box 3 controls the hydraulic rod 804 and the sound and light alarm 401 to run simultaneously, and cuts off the power supply of the drive motor 103. The radar microwave sensor 502, the camera 501 and the BIM control box 3 are used to monitor the operating status of the tower crane and the position of surrounding objects in real time, so as to timely discover and warn of potential safety hazards, thereby effectively reducing the probability of accidents.

When the driving motor 103 is powered on, the face gear disc 105 is driven to rotate through the transmission rod 104. The rotating face gear disc 105 drives the meshing first gear assembly 106 to rotate. The rotating first gear assembly 106 drives the rotating seat 2 to rotate through the meshing face gear ring 201. The rotating rotating seat 2 drives the tower crane arm 4 to rotate and reverse.

[0025] like Figure 1 As shown, a sound and light alarm 401 is fixedly installed at one end of the tower crane arm 4, and the sound and light alarm 401 is electrically connected to the BIM control box 3 through a wire; When the BIM control box 3 detects that the tower crane arm 4 is in danger of collision, the BIM control box 3 promptly turns on the sound and light alarm 401 to send out a sound and light alarm to warn the staff to operate safely to prevent accidents.

[0026] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
