Description

Technical Field

[0001] The utility model relates to the technical field of photographic equipment, in particular to a tower crane camera. Background Art

[0002] The tower crane is abbreviated as tower crane, also known as tower hoist, and originated in Western Europe. It is mainly used for the vertical and horizontal transportation of materials and the installation of building components in house construction, and has a large working space.

[0003] The monitoring camera equipped on the tower crane can record the scenes during the operation. Once a problem occurs, the monitoring system can quickly feedback to the operator, enabling them to immediately take measures to prevent possible dangerous situations. The tower crane camera is generally installed on the jib. During the movement of the jib, its installation angle constantly changes, and the tower crane camera installed on the jib needs to maintain a vertically downward state. Therefore, many tower crane cameras adopt a hanging type or an angle-adjustable camera, using gravity to set the camera vertically downward.

[0004] However, in this hanging method, when the jib moves, the tower crane camera is prone to long-term shaking, affecting construction safety and operation efficiency, and is also relatively vulnerable to the influence of wind, affecting the monitoring effect. Moreover, the long-term shaking may cause the tower crane camera to be unstable and fall off, resulting in safety accidents. Summary of the Utility Model

All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts belong to the scope of protection of the present disclosure.

[0030] Embodiment 1

[0031] As Figure 1As shown in the figure, a tower crane camera includes a mounting bracket and a camera assembly 1 disposed on the mounting bracket. The camera assembly 1 is communicatively connected to a display device through a wireless transmission module 10. The wireless transmission module 10 is a wireless communication module such as Bluetooth or Wi-Fi, which is used to upload the picture information collected by the camera assembly 1 to the display device for display. The operator can understand the operation status of the tower crane from the display device. The wireless transmission module 10 is installed inside an antenna. One end of the antenna is a sleeve section with internal threads. A through hole is provided on the side wall of the camera assembly 1. A stud is inserted into the through hole. One end of the stud is provided with an abutting portion for abutting against the inner side wall of the outer shell 15 of the camera assembly 1, and the other end extends out of the through hole for threaded connection with the sleeve section at one end of the antenna, so as to install the wireless transmission module 10 on the camera assembly 1 by installing a screw with external threads into a threaded hole provided on the camera assembly 1.

[0032] Among them, the mounting bracket includes a positioning plate 2. The positioning plate 2 is fixedly installed on the boom through a fixing member. The fixing member includes a bolt 20 and a nut 21. By providing a through hole on the boom, the positioning plate 2 can be fixedly installed on the boom. This installation method is relatively safe, and there is almost no risk of the positioning portion 2 falling off. Another fixing method is to fix the positioning plate 2 to a magnetic attraction block 22 through a bolt 20 and a nut 21, and use the magnetic attraction block to adsorb on the boom. This installation method is very convenient and suitable for installation at high altitudes. However, there is a small probability of falling risk when using magnetic attraction in the event of strong winds and heavy rains. Therefore, it is also necessary to provide a threaded hole on the side of the outer shell 15 of the camera assembly 1. An upper mounting lifting ring 17 with a screw is installed in the threaded hole. A rope or steel cable is installed on the lifting ring 17. The other end of the rope or steel cable is fixed in the operating room. Even if the magnetic attraction block 22 falls off, the rope or steel cable can still hold the camera assembly 1 to prevent it from falling, so as to avoid causing a safety accident.

[0033] On the other side of the positioning plate 2, there is a turntable 31. A bearing is provided at the center of the turntable 31. The bearing is fixedly installed on the positioning plate 2, so that the turntable 31 can rotate outside the bearing. A rotating frame 3 is provided on the turntable 31. The rotating frame 3 includes two oppositely arranged connecting portions 32. An installation plate 4 is provided between the two connecting portions 32. The installation plate 4 is respectively rotatably connected to the two connecting portions 32 through hinge shafts 33 on both sides, so that the installation plate 4 can rotate in a vertical plane along the hinge shafts 33. The plane where the rotation path of the installation plate 4 is located is perpendicular to the plane where the rotation path of the rotating frame 3 is located. The camera assembly 1 is installed on the installation plate 4. Therefore, the camera assembly 1 can be unrestricted in all directions and be in a vertical state.

[0034] Combined with Figure 2 and Figure 3As shown in the figure, a plurality of threaded mounting holes 13 are provided on the outside of each side of the housing 15 of the camera assembly 1. The counterweight 12 can be fixed to the bottom of the side of the housing 15 by a screw 14 passing through the mounting through hole provided in the counterweight 12, thereby reducing the center of gravity of the camera assembly 1. When the jib moves or is blown by the wind, it is not easy to shake, and it can quickly return to the upright state and remain stationary after shaking, ensuring the imaging quality.

[0035] As Figure 4 and Figure 5 As shown in the figure, a camera is provided inside the housing 15. A transparent protective layer is provided at the bottom of the housing 15 for protecting the camera 11 at the bottom of the camera. A fixing frame 16 is provided inside the housing 15. The fixing frame 16 abuts against both sides of the camera 11. The camera 11 is installed in the fixing frame 16 by positioning screws, thereby ensuring the stability of the camera 11 and making it not easy to shake. The lens at the bottom of the camera 11 is oriented towards the transparent protective layer.

[0036] The housing 15 is detachably arranged. The disassembly structure is similar to a flange. The upper and lower shell covers of the housing 15 are fixed together through the threaded holes provided on the side, which is convenient for disassembling to repair and maintain the camera 11 or the internal circuit.

[0037] After the tower crane camera of the present utility model is installed on the jib, the camera 11 is not restricted in all directions and can still return to the vertical state after the jib moves, ensuring the imaging quality. And counterweights 12 are installed on each side outside the housing 15. The counterweights are symmetrically arranged to balance the forces in all directions, so that the center of gravity of the camera assembly 1 is located at a position with a lower center of gravity. With such a setting, whether the camera assembly 1 generates an angular change following the movement of the jib or shakes due to being blown by the wind, the stability of the camera assembly will be improved, and it can quickly return to the vertical state, as much as possible ensuring the monitoring quality, which is beneficial to the safe progress of the construction and is suitable for popularization and use.

[0039] In the present utility model, unless otherwise clearly specified and limited, the first feature being "on" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. The meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise clearly specifically limited.
