Specific implementation manners

[0030] The present utility model will be further introduced below in conjunction with the accompanying drawings and specific embodiments:

[0031] Refer to Figures 1 to 6 , a single-track crane carbon monoxide monitoring device, including: a carbon monoxide sensor 4, a power-off instrument, a semi-closed housing 1 and a plate body 11.

[0032] Among them, the carbon monoxide sensor 4 is used to detect the carbon monoxide concentration. In actual applications, sensors for detecting methane and relevant sensors for possible poisonous gases can also be used in combination. These sensors detect the concentrations of relevant gases. When the detection results exceed the preset threshold, the relevant alarm module is controlled to alarm.

[0033] The power-off instrument is connected in series in the electric control system of the single-track crane. The signal output end of the carbon monoxide sensor 4 is electrically connected to the power-off instrument. Here, the electric control system controls the operation of the locomotive of the single-track crane. Carbon monoxide is generated when the locomotive is running. When the carbon monoxide sensor 4 detects that the carbon monoxide concentration is too high, relevant signals are transmitted to the power-off instrument, and the power-off instrument disconnects the electric control system, so that the locomotive can stop running.

[0034] The opening of the semi-closed housing 1 is fixedly installed on the side of the single-track crane in a fitting manner. When the semi-closed housing 1 is installed on the side of the single-track crane, the opening of the semi-closed housing 1 is closed; for example Figure 1As shown, the opening of the semi-closed housing 1 is a plane, which can be installed in the plane area on the side of the single-rail hoist. The carbon monoxide sensor 4 is fixedly arranged inside the semi-closed housing 1, and the carbon monoxide sensor 4 is used to detect the carbon monoxide concentration of the gas inside the semi-closed housing 1.

[0035] An inner air inlet hole 10 is opened on the outer side surface of the semi-closed housing 1. A plate body 11 is fixedly connected to the outside of the semi-closed housing 1. The plate body 11 covers the inner air inlet hole 10. An outer air inlet hole 14 is opened on the plate body 11, and the outer air inlet hole 14 is staggered from the inner air inlet hole 10; an annular gasket 12 is arranged between the plate body 11 and the semi-closed housing 1. The material of the annular gasket 12 is an elastic material. Under the action of the annular gasket 12, there is always a gap between the plate body 11 and the outer side of the semi-closed housing 1. When the single-rail hoist is running, the plate body 11 is blown by the airflow generated by the movement and fits against the side surface of the semi-closed housing 1, and both the outer air inlet hole 14 and the inner air inlet hole 10 are blocked. At this time, not too much gas will enter the inside of the semi-closed housing 1, avoiding a lot of dust-carrying gas from entering the semi-closed housing 1 during the movement of the single-rail hoist. When the single-rail hoist stops and feeds materials in the underground roadway, the outer air inlet hole 14, the inner air inlet hole 10, and the gap between the plate body 11 and the outer side of the semi-closed housing 1 form an air flow channel, and the inside and outside of the semi-closed housing 1 are connected. The carbon monoxide sensor 4 located inside the semi-closed housing 1 can detect without obstruction. When the carbon monoxide sensor 4 detects that the carbon monoxide concentration is too high, it will transmit a signal to the power-off instrument, causing the electric control system of the single-rail hoist to power off and the locomotive to shut down, ensuring the safety of the personnel in the roadway.

[0036] In one embodiment, the opening of the semi-closed housing 1 corresponds to the side surface of the single-rail hoist, and a mounting plate 2 is fixedly connected to the outer edge of the opening of the semi-closed housing 1. A first mounting hole 3 is opened on the mounting plate 2, and the mounting plate 2 can be fixedly connected to the side surface of the single-rail hoist using screws.

[0037] In one embodiment, rubber protrusions 13 are arranged on both the inner and outer sides of the plate body 11. The rubber protrusion 13 located on the inner side of the plate body 11 corresponds to the inner air inlet hole 10, that is, the rubber protrusion 13 located on the inner side of the plate body 11 is half inserted into the inner air inlet hole 10. When the plate body 11 is close to the outer side surface of the semi-closed housing 1, the rubber protrusion 13 located on the inner side of the plate body 11 is completely inserted into the inner air inlet hole 10 to better block the inner air inlet hole 10.

[0038] In one embodiment, a fan-shaped inner concave portion 6 is arranged on the side surface of the semi-closed housing 1, and the fan-shaped inner concave portion 6 forms a fan-shaped chamber on the outside of the semi-closed housing 1. A first side plate 7 is rotatably installed on the inner side of the fan-shaped chamber. A second side plate 8 is fixedly connected to the side surface of the first side plate 7, and a display module 9 is fixedly connected to the second side plate 8. The display module 9 is the display screen of the carbon monoxide sensor 4.

[0039] As Figure 5As shown in the figure, the second side plate 8 is closer to the inside of the fan-shaped chamber: in one state, the first side plate 7 is in an outwardly open state, and the display module 9 is substantially flush with the side of the semi-closed housing 1, and the user can operate the display module 9; in another state, the first side plate 7 is in a closed state, and the second side plate 8 and the display module 9 are both located inside the fan-shaped chamber, so as to better protect the display module 9.

[0040] An anti-collision pad is fixedly connected to the inside of the fan-shaped chamber to prevent the second side plate 8 from colliding with the inner wall of the fan-shaped chamber.

[0041] In one embodiment, a restricting member 16 is rotatably connected to the side of the semi-closed housing 1 and on one side of the fan-shaped chamber. When the first side plate 7 is in a closed state, the restricting member 16 is toggled to the outside of the first side plate 7 to restrict the first side plate 7 from opening outward.

[0042] In one embodiment, second mounting holes 15 are provided at the four corners of the plate body 11, and the plate body 11 is connected to the semi-closed housing 1 by using screws. Specifically, the screws pass through the second mounting holes 15 on the plate body 11, and then the screws are threadedly connected to the semi-closed housing 1.

[0043] In one embodiment, a baffle 5 is fixedly connected to the inside of the semi-closed housing 1 at a position corresponding to the inner air inlet hole 10. The baffle 5 is used to block the carbon monoxide sensor 4 so that the gas entering the inside of the semi-closed housing 1 does not directly blow to the carbon monoxide sensor 4, effectively protecting the carbon monoxide sensor 4.

[0044] The above content is a further detailed description of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or substitutions can be made, and all should be regarded as belonging to the protection scope of the present invention.
