[0002] A tower crane blind spot visualization system is a technology solution used to improve construction site safety. It typically involves cameras and other sensor equipment mounted on a tower crane that capture images of areas beyond the crane operator's line of sight and transmits them in real time to a display screen inside the cockpit.

[0003] Chinese patent publication number CN106698200B, published on March 27, 2018, discloses a monitoring system for solving the blind spot of tower crane hoisting, including a camera device, a first wireless network bridge, a display screen, a first controller, a photovoltaic power generation device and a battery. The first wireless network bridge includes a wireless camera transmitter and a wireless camera receiver. The wireless camera transmitter is fixed on the amplitude trolley frame, and its signal input end is electrically connected to the signal output end of the camera, and its signal output end is wirelessly connected to the wireless camera receiver; the wireless camera receiver is installed in the control room of the tower crane, the wireless camera receiver is electrically connected to the first controller, and the signal output end of the first controller is electrically connected to the display.

[0004] Existing tower crane blind spot visualization systems such as the above-mentioned ones mostly use wireless cameras, and the cameras are fixed on the amplitude trolley. During the specific implementation process, since the tower crane's walkway is integrated on the top, the connection component between the camera and the amplitude trolley is facing downward, which makes it inconvenient to subsequently disassemble and repair the wireless camera. Therefore, it is urgent to propose a corresponding tower crane blind spot visualization system using cameras to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems and to propose a camera installation structure for a tower crane blind spot visualization system.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A camera mounting structure for a tower crane blind spot visualization system includes a camera body, a support base, and a mounting assembly for fixing the support base. The support base is provided with a gradient-distributed step one and step two. The top of the camera body is detachably connected to a bracket, the bottom of the bracket abuts against the top of step two, the top of the bracket is rotatably connected to a pressure plate, the bottom of the pressure plate overlaps the top of step one, the outer wall of the pressure plate is screwed together with the inner wall of the support base, and the top of the pressure plate is fixedly connected to a lifting ring.

[0008] Preferably, a mounting ring is fixedly connected to the top of the camera body, the mounting ring is fixedly connected to the bottom of the bracket through a fastening rod, and the bottom of the mounting ring and the bottom of the bracket are located in the same horizontal plane.

[0009] Preferably, a rubber ring is fixedly connected to the top of the second step.

[0010] Preferably, a convex piece is integrally formed on the outer surface wall of the horizontal end of the support seat, and a locking rod is screwedly connected to the inner surface wall of the convex piece.

[0011] Preferably, the outer surface wall of the bracket is fixedly connected with a convex strip, and the outer surface wall of the convex strip is engaged with the inner surface wall of the support seat through a vertical groove.

[0012] Preferably, a rotating block is fixedly connected to the bottom of the pressing plate, and the outer surface wall of the rotating block is rotatably connected to the inner surface wall of the top of the bracket.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0014] 1. In the present application, the support base is adjusted to the middle of the trolley by cooperating with the protruding piece and the locking rod, and the camera body and the bracket are fixed by cooperating with the mounting ring and the fastening rod. Then the camera is combined with the support base, and the pressure plate is rotated to screw it with the inner surface wall of the support base. The convex strips and vertical grooves on the outer wall of the camera body slide to limit the axial deflection of the camera body. The screwing of the rotating block with the top of the bracket does not affect the independent rotation of the pressure plate on the one hand, and realizes the vertical linkage between the pressure plate and the bracket on the other hand, until the pressure plate abuts step one, at which time the bracket is combined with step two, thereby realizing the stable installation of the camera body. Subsequently, you only need to rotate and lift the pressure plate to remove the camera body from above the support base, ensuring the convenience of inspection and replacement of the camera body.

[0015] 2. In this application, the bottom of the mounting ring is flush with the bottom of the bracket. When the bottom of the bracket is combined with step 2, the bottom of the mounting ring and the fastening rod are also combined with step 2. At this time, the position restriction and the contact friction between step 2 and fastening rod 2 can effectively limit the loosening of the fastening rod, and the rubber ring ensures the tightness of the contact between step 2 and the fastening rod.

The support base 1 is provided with a gradient-distributed step 1 7 and a step 2 8. The top of the camera body 5 is detachably connected to a bracket 11, the bottom of the bracket 11 abuts against the top of the step 2 8, the top of the bracket 11 is rotatably connected to a pressure plate 4, the bottom of the pressure plate 4 overlaps the top of the step 1 7, the outer wall of the pressure plate 4 is screwed to the inner wall of the support base 1, and the top of the pressure plate 4 is fixedly connected to a lifting ring 6;

[0025] By cooperating with the protruding piece 2 and the locking rod 3, the support seat 1 is moved to the middle of the amplitude trolley, and the camera body 5 and the bracket 11 are fixed together by the mounting ring 12 and the fastening rod 13. Then the camera is combined with the support seat 1, and the pressure plate 4 is rotated to screw it with the inner surface wall of the support seat 1. The convex strip 14 on the outer wall of the camera body 5 slides with the vertical groove 9, which can limit the axial deflection of the camera body 5. The screwing of the rotating block 15 and the top of the bracket 11 does not affect the independent rotation of the pressure plate 4 on the one hand, and realizes the vertical linkage between the pressure plate 4 and the bracket 11 on the other hand, until the pressure plate 4 abuts against step 1 7. At this time, the bracket 11 is combined with step 2 8 to achieve stable installation of the camera body 5. Subsequently, you only need to rotate and lift the pressure plate 4 to remove the camera body 5 from the top of the support seat 1, ensuring the convenience of maintenance and replacement of the camera body 5.

[0026] Specifically, such as Figure 2 and Figure 4As shown, a mounting ring 12 is fixedly connected to the top of the camera body 5, and the mounting ring 12 is fixedly connected to the bottom of the bracket 11 through a fastening rod 13, and the bottom of the mounting ring 12 and the bottom of the bracket 11 are located in the same horizontal plane, and a rubber ring 10 is fixedly connected to the top of the step 2 8, and the bottom of the mounting ring 12 is flush with the bottom of the bracket 11. When the bottom of the bracket 11 is combined with the step 2 8, the bottom of the mounting ring 12 and the fastening rod 13 are also combined with the step 2 8. At this time, the loosening of the fastening rod 13 can be effectively limited by position limitation and the contact friction between the step 2 8 and the fastening rod 2 13, and the rubber ring 10 ensures the tightness of the contact between the step 2 8 and the fastening rod 13.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the outer wall of the horizontal end of the support seat 1 is integrally formed with a protruding piece 2, and the inner wall of the protruding piece 2 is screwed and connected with a locking rod 3. Through the cooperation of the protruding piece 2 and the locking rod 3, the support seat 1 is adjusted to the middle of the trolley. The outer wall of the bracket 11 is fixedly connected with a convex strip 14, and the outer wall of the convex strip 14 is engaged with the inner wall of the support seat 1 through the vertical groove 9.

Then the camera is combined with the support seat 1, and the pressure plate 4 is rotated to screw it with the inner surface wall of the support seat 1. The convex strip 14 on the outer wall of the camera body 5 slides with the vertical groove 9 to limit the axial deflection of the camera body 5. The screwing of the rotating block 15 and the top of the bracket 11 does not affect the independent rotation of the pressure plate 4 on the one hand, and realizes the vertical linkage between the pressure plate 4 and the bracket 11 on the other hand, until the pressure plate 4 abuts against the step 7, at which time the bracket 11 is locked. By closing the step 2 8, the camera body 5 can be stably installed. Subsequently, the camera body 5 can be removed from the support base 1 by simply rotating and lifting the pressure plate 4, which ensures the convenience of repairing and replacing the camera body 5. The bottom of the mounting ring 12 is flush with the bottom of the bracket 11. When the bottom of the bracket 11 is combined with the step 2 8, the bottoms of the mounting ring 12 and the fastening rod 13 are also combined with the step 2 8. At this time, the loosening of the fastening rod 13 can be effectively limited by position limitation and the contact friction between the step 2 8 and the fastening rod 2 13, and the rubber ring 10 ensures the tightness of the contact between the step 2 8 and the fastening rod 13.
