Description

Technical Field

[0001] The utility model relates to the technical field of shield machines, in particular to a manhole of a shield machine. Background Art

[0002] The shield machine manhole is a chamber inside the shield machine where the shield machine operator rests, lives, and works. The installation of a manhole is crucial to the smooth operation of the shield machine and the operator's working conditions. Properly setting up and managing the manhole can improve the operator's work efficiency, ensure their safety and health, and facilitate the control and management of the construction progress.

[0003] Existing shield machine manholes are either not equipped with cameras, resulting in a low degree of visualization, which makes it inconvenient for construction workers to view the external construction progress and conditions in the manhole, making it inconvenient for construction workers to control and manage the construction progress; or cameras are installed outside the shield machine manhole, and the camera wires are passed through the side walls of the shield machine manhole to connect to the display module inside the shield machine manhole. On the one hand, the camera is always exposed to the outside of the shield machine manhole, occupying external space and easily damaged. On the other hand, the camera is easily contaminated, which affects the camera effect. Utility Model Content

[0030] Figures 1 to 5 An embodiment of a shield machine manhole of the present invention is shown. The shield machine manhole of this embodiment includes a chamber 1 arranged in a shield machine 2. An inlet and outlet 3 is provided on the side wall 11 of the chamber 1 facing the shield machine 2. A protection box 4 is provided in the chamber 1. An opening 41 is provided on one side of the protection box 4. The opening 41 is connected to the inlet and outlet 3. A camera 5 is provided in the protection box 4. An inlet and outlet drive mechanism 6 is provided on the protection box 4 for driving the camera 5 to enter and exit the protection box 4 through the opening 41 and the inlet and outlet 3. A door panel 7 for opening and closing the opening 41 and an opening and closing drive mechanism 8 for driving the door panel 7 to open and close are provided on the protection box 4.

[0031] In this shield machine man chamber, when the camera 5 is in use, the opening and closing drive mechanism 8 causes the door panel 7 to open the opening 41. The in-and-out drive mechanism 6 then drives the camera 5 through the opening 41 and the entrance 3 to extend out of the protective box 4, making it easier to observe the external construction of the shield machine 2 and facilitate construction management for workers inside the chamber 1. When the camera 5 is not in use, the in-and-out drive mechanism 6 drives the camera 5 through the opening 41 and the entrance 3 to enter the protective box 4, avoiding occupying the external space of the chamber 1 and preventing the camera 5 from being exposed to the outside and damaged. Furthermore, the opening and closing drive mechanism 8 can drive the door panel 7 to move to close the opening 41, thereby preventing damage to the camera 5 during the construction of the shield machine 2 and preventing contamination of the camera 5 that would affect the camera's performance.

[0032] Furthermore, in this embodiment, a reaction frame 12 located outside the protection box 4 is provided in the chamber 1 , and the in-and-out drive mechanism 6 and the opening and closing drive mechanism 8 are both mounted on the reaction frame 12 .

[0033] Furthermore, if Figure 3 and Figure 4 As shown, in this embodiment, the in-and-out drive mechanism 6 includes an in-and-out drive motor 61, a sliding seat 62, and a first transmission assembly 63. The sliding seat 62 slides on the protective box 4, and the camera 5 is mounted on the sliding seat 62. The in-and-out drive motor 61 is mounted on the reaction frame 12 and connected to the sliding seat 62 via the first transmission assembly 63. When the in-and-out drive motor 61 is running, it drives the sliding seat 62 to slide via the first transmission assembly 63, thereby driving the camera 5 to enter and exit the protective box 4 through the opening 41 and the entrance 3.

[0034] Furthermore, in this embodiment, the first transmission assembly 63 includes a first rack 631 and a first gear 632 that mesh with each other. The first gear 632 is disposed on the output shaft of the in-and-out drive motor 61, and the first rack 631 is disposed on the sliding seat 62. The first transmission assembly 63 is capable of converting the rotational motion of the in-and-out drive motor 61 into linear motion of the sliding seat 62, thereby driving the camera 5 to enter and exit the protective box 4 through the opening 41 and the access port 3.

[0035] Furthermore, in this embodiment, the first gear 632 is located outside the protection box 4 , and the sliding seat 62 is movably provided on the end wall of the protection box 4 away from the opening 41 .

[0036] Furthermore, in this embodiment, the opening and closing drive mechanism 8 includes an opening and closing drive motor 81 and a second transmission assembly 82. The door panel 7 is slidably mounted on the protective box 4. The opening and closing drive motor 81 is mounted on the reaction frame 12 and is connected to the door panel 7 via the second transmission assembly 82. When the opening and closing drive motor 81 is running, it drives the door panel 7 to slide via the second transmission assembly 82, thereby enabling the door panel 7 to open and close the opening 41.

[0037] Furthermore, in this embodiment, the second transmission assembly 82 includes a second rack 821 and a second gear 822 that mesh with each other. The second gear 822 is disposed on the output shaft of the opening and closing drive motor 81, and the second rack 821 is disposed on the door panel 7. This second transmission assembly 82 is capable of converting the rotational motion of the opening and closing drive motor 81 into linear motion of the door panel 7, thereby enabling the door panel 7 to open and close the opening 41. Specifically, both the in-and-out drive motor 61 and the opening and closing drive motor 81 are bidirectional motors.

[0038] Furthermore, in this embodiment, a cleaning mechanism 9 for cleaning the camera 5 is provided on the protection box 4. The cleaning mechanism 9 is used to clean the lens of the camera 5 to prevent dust or debris from adhering.

[0039] Furthermore, in this embodiment, the cleaning mechanism 9 includes an air pump 91, an air pipe 92, and a nozzle 93. The air pump 91 is mounted on the outer wall of the protective box 4 and is located within the chamber 1. The nozzle 93 is mounted on the protective box 4 and extends into the protective box 4. The nozzle 93 is connected to the air pump 91 via the air pipe 92. When the air pump 91 is activated and the nozzle 93 is ejected through the air pipe 92, the ejected air blows away dust and other debris adhering to the camera 5, thereby preventing the camera 5 from affecting the image clarity.

[0040] Preferably, the nozzle 93 is installed at an angle at the bottom of the protection box 4 so that the nozzle 93 can just face the position of the camera 5 after it is reset.

[0041] Furthermore, in this embodiment, an isolation shell 21 is provided in the shield machine 2 , the chamber 1 is formed in the area enclosed by the outer shell 22 of the shield machine 2 and the isolation shell 21 , and the side wall 11 is formed on the isolation shell 21 .

[0042] Preferably, a sealed space is formed between the reaction frame 12 and the isolation shell 21 to improve the airtightness inside the chamber 1. The protection box 4 is fixed on the side wall 11.

[0043] The process of using the shield machine man chamber is as follows: when it is necessary to check the construction status of the shield machine 2, the opening and closing drive motor 81 is first controlled to drive the second gear 822 to rotate. The second gear 822 drives the door panel 7 to move through the meshing action with the second rack 821. After the door panel 7 opens the opening 41, the entry and exit drive motor 61 is controlled to drive the first gear 632 to rotate. The first gear 632 drives the camera 5 to extend out of the protective box 4 through the meshing action with the first rack 631. The staff inside the chamber 1 uses the camera 5 to check the surrounding construction progress. After checking, the camera 5 is retracted into the protective box 4 and the door panel 7 is closed again. When dust or debris adheres to the camera 5, the air pump 91 is started and the nozzle 93 is sprayed through the air pipe 92. The sprayed gas blows away the dust and other debris adhered to the camera 5 to avoid affecting the shooting clarity of the camera 5.
