[0038] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0039] The rotary platform of the present utility model is described below with reference to the accompanying drawings.

[0040] The utility model provides a rotary platform, such as Figure 1 , Figure 2 and Figure 3 As shown, the rotary platform includes:

[0041] A platform body 1, a walking corridor 11, a corridor handrail 12 and a wiring plug 13 are provided on the lateral side of the platform body 1, the wiring plug 13 is connected from the power supply part of the platform body 1 and extends to the lateral side of the platform body 1, and the walking corridor 11 is detachably arranged; and

[0042] The side monitoring mechanism 2 includes a side camera unit 21 installed on the lateral edge of the walking corridor 11. The detection part of the side camera unit 21 is staggered with the corridor handrail 12, and the power input terminal of the side camera unit 21 is detachably connected to the wiring plug 13.

[0043] By setting the side camera unit 21 on the lateral edge of the walking corridor 11, it is possible to avoid the walking corridor 11 and the corridor handrail 12 blocking the field of view of the side camera unit 21, so that the side monitoring mechanism 2 can also perform all-round monitoring of the situation near the walking corridor 11. For example, when a person is climbing the walking corridor 11, the side camera unit 21 can monitor the movement of the person in time by rotating the camera. By setting the wiring plug 13 on the lateral side of the platform body 1, when the rotary platform needs to be transferred and transported, it is only necessary to unplug the side camera unit 21 from the wiring plug 13, and then disassemble the walking corridor 11 and the side camera unit 21 as a whole, so as to solve the problem of road width limitation during transfer and transportation. When the rotary platform is transported to the destination, it is only necessary to install the walking corridor 11, and then connect the power input end of the side camera unit 21 with the wiring plug 13, so that the side monitoring mechanism 2 can work normally. In summary, the revolving platform in the utility model can not only solve the technical problem that the existing walking corridor 11 and corridor handrail 12 block the field of view of the side monitoring mechanism 2, but also avoid the influence of the disassembly and assembly of the walking corridor 11 on the function of the side monitoring mechanism 2 by setting a wiring plug 13 on the lateral side of the platform body 1 and fixing the side camera unit 21 on the walking corridor 11.

[0044] It should be noted that the side camera unit 21 of the present invention is preferably a camera capable of rotating at multiple angles or a fisheye wide-angle lens.

[0045] like Figure 3 As shown, in the embodiment of the utility model, a wiring channel 16 is provided on the lateral side of the platform body 1, and the wiring channel 16 is located below the walking corridor 11 and is used for the wiring plug 13 to pass through. By providing the wiring channel 16, the wiring of the wiring plug 13 can be facilitated.

[0046] like Figure 2 and Figure 3 As shown, in the embodiment of the utility model, the lateral edge of the walking corridor 11 is provided with a protective edge 111, the side camera unit 21 is located on the inner side of the protective edge 111 and the detection part of the side camera unit 21 is arranged higher than the protective edge 111, and the detection part of the side camera unit 21 is staggered with the corridor handrail 12. By arranging the side camera unit 21 on the inner side of the protective edge 111, the side camera unit 21 can be protected when the revolving platform is working or when the walking corridor 11 is disassembled for transportation, so as to prevent obstacles from scratching the side camera unit 21, and at the same time, it can prevent the objects on the walking corridor 11 from falling from the edge. By arranging the detection part of the side camera unit 21 to be staggered with the corridor handrail 12, it can be prevented that the corridor handrail 12 blocks the side camera unit 21.

[0047] like Figure 3 and Figure 4 As shown, in an embodiment of the present invention, a mounting seat 14 is provided on the inner side of the protective edge 111, and the top height of the mounting seat 14 is higher than the protective edge 111. The side camera unit 21 can be installed on the top of the mounting seat 14 by means of threaded connectors or other connectors.

[0048] like Figure 4 As shown, in the embodiment of the utility model, the side camera unit 21 includes a camera body 211 and a water shield, the water shield includes side protective plates 212 arranged on both sides of the camera body 211, a top protective plate 213 arranged on the top of the camera body 211, and a back protective plate 214 arranged on the back side of the camera body 211, the side protective plates 212 are fixedly mounted on the top of the mounting seat 14 through threaded connectors or other connectors, and the camera body 211 is suspended between the two side protective plates 212. By providing the water shield, the camera body 211 can be protected in rainy weather, and the exposed area of ​​the camera body 211 can be reduced to prevent the accumulation of construction site dust on the surface of the camera body 211.

[0049] like Figure 1 , Figure 2 and Figure 3As shown, in an embodiment of the utility model, an entry and exit channel 15 is also provided on the lateral edge side of the walking corridor 11, and the entry and exit channel 15 is embedded in the walking corridor 11. A corner 112 bent laterally inward is formed between the side of the walking corridor 11 and the entry and exit channel 15, and the side camera unit 21 is arranged at the corner 112 and located on the inner side of the protective edge 111. People mainly climb to the walking corridor 11 through the access passage 15 and the ladder vertically arranged in the access passage 15. In order to reduce the lateral width of the rotating platform, the access passage 15 is generally embedded in the walking corridor 11. Therefore, when people climb in the access passage 15, if the camera is installed at a high position of the main body, it is sometimes difficult for the camera to timely detect the people in the access passage 15. By arranging the side camera unit 21 at the corner 112 where the walking corridor 11 and the access passage 15 intersect, the camera can monitor the situation near the lateral edge of the walking corridor 11 and the access passage 15, thereby greatly increasing the monitoring field of the side camera unit 21 near the walking corridor 11. At the same time, arranging the side camera unit 21 at the corner 112 can avoid occupying the walking corridor 11 and causing obstacles to people's walking, and reduce the probability of the side camera unit 21 being "stepped on" or "kicked".

[0050] like Figure 6 As shown, in the embodiment of the utility model, the walking corridor 11 includes a left platform corridor and a right platform corridor respectively arranged on the lateral sides of the platform body 1, and the side camera unit 21 includes a left camera unit and a right camera unit, and the left camera unit and the right camera unit are respectively installed on the left platform corridor and the right platform corridor. That is, the side camera units 21 are arranged on the lateral sides of the platform body 1, and no further description is given here.

[0051] like Figure 1 and Figure 5 As shown, in the embodiment of the present utility model, the rotary platform further comprises a front camera unit 3, and the front camera unit 3 is arranged on the front upper side of the platform body 1. By arranging the front camera unit 3, real-time image monitoring of the front side of the rotary platform can be performed.

[0052] like Figure 1 and Figure 5As shown, in the embodiment of the utility model, the platform body 1 includes a control room 17 and a heat sink 18 located at the front side and arranged side by side laterally, and the front camera unit 3 is installed on the heat sink 18. The surrounding side of the control room 17 is generally surrounded by transparent glass, and the operator can observe the situation near the control room 17 with the naked eye in the control room 17, but because the side of the control room 17 is blocked by the heat sink 18, there are a lot of blind spots near the heat sink 18. In order to monitor the field of vision near the heat sink 18, the front camera unit 3 can be installed on the front side of the heat sink 18. Through the cooperation of the front camera unit 3 and the side camera unit 21 on the corresponding side, the blind spots near the heat sink 18 can be monitored.

[0053] like Figure 1 and Figure 5 As shown, in the embodiment of the present utility model, the control room 17 and the heat sink 18 may also be equipped with a rearview mirror 6 .

[0054] like Figure 6 As shown, in the embodiment of the present utility model, the rotary platform further comprises a rear camera unit 4, which is arranged on the upper rear side of the platform body 1. By arranging the rear camera unit 4, the rear side of the rotary platform can be monitored in real time.

[0055] like Figure 6 As shown, in the embodiment of the utility model, the platform body 1 includes a counterweight 19 located at the rear side, and the rear camera unit 4 is arranged above the rear side of the counterweight 19. Since the counterweight 19 is large in size, it is difficult for the operator in the control room 17 to directly observe the situation at the rear side of the rotary platform, so the rear camera unit 4 can be installed on the counterweight 19 to monitor the field of view behind the counterweight 19.

[0056] In the embodiment of the present invention, the arrangement of the front camera unit 3 and the rear camera unit 4 may be the same as that of the side camera unit 21 .

[0057] like Figure 5 and Figure 6 As shown, in the embodiment of the present utility model, a lighting unit 5 is further provided on the lateral side of the platform body 1, and / or the front side of the platform body 1, and / or the rear side of the platform body 1. By providing the lighting unit 5, the detection area of ​​the camera unit can be illuminated.

[0058] To achieve the above purpose, the utility model also provides an excavator, wherein the excavator includes the slewing platform described above. Since the excavator adopts all the technical solutions of the above embodiments, it at least has the beneficial effects brought by the above embodiments, which will not be repeated here. Of course, the slewing platform in the utility model can also be used on engineering vehicles such as cranes and straddle vehicles.

[0059] In summary, the revolving platform in the utility model can eliminate the blind spots near the walking corridor 11 and monitor the surroundings of the revolving platform by optimizing the installation position of the monitoring mechanism, thereby improving the safety of the operation. At the same time, the side monitoring mechanism 2 can be disassembled together with the walking corridor 11 and is very convenient to install again.
