Description

Technical Field

[0001] The utility model relates to the mining field, in particular to the mining monorail crane auxiliary transportation technology field, specifically refers to a mining intrinsically safe camera used for a monorail crane locomotive. Background Art

[0002] As an auxiliary transportation equipment for coal mines, monorail crane locomotive has the advantages of strong safety, strong driving force, strong adaptability, small space occupation and high transportation efficiency. It is widely used in narrow spaces such as tunnels and mines. It is an auxiliary transportation equipment suitable for most coal mines in my country. Monorail crane locomotive is a kind of equipment that relies on explosion-proof diesel engine or battery to provide power. The locomotive can move along the track suspended above the tunnel or mine. First of all, monorail locomotives are mainly used to transport equipment and materials, and the transportation environment is complex and diverse. In mines, the transportation routes can be divided into transportation tunnels, transportation chute and cutting work areas. Some sections of the tunnels are undulating, the road surface is poorly flat, and there is no lighting or poor lighting in the tunnels. The driver and passengers of the monorail locomotive cannot identify the front and rear transportation environment in the above harsh environment with the naked eye. Secondly, the cab of the monorail locomotive is arranged according to the overall layout of the locomotive. Therefore, there may be materials being transported in front and behind the cab, which will block the line of sight and make it impossible to observe the front and rear transportation environment. Therefore, considering the above problems, it is necessary to install an "electronic eye" device, that is, a camera, at both ends of the monorail locomotive to observe the transportation environment of the monorail locomotive. It is very important for the safe transportation of the monorail locomotive.

[0003] The common video camera equipment in the industry now is relatively simple, and has the following main problems. First, the core components of the camera are the lens and the camera head. The camera is required to be an intrinsically safe device, while the camera head and the lens are generally civilian equipment. The protective shell of the camera has no protective equipment, and the lens module is directly exposed to the transportation environment. This approach can significantly improve the clarity in the early stage of transportation, but in the later stage of transportation, due to the harsh transportation environment, the lens will be contaminated with dust, resulting in a decrease in clarity or even damage to the lens. Second, the existing camera has a simple working state and a single observation direction, which can only be the front and back direction. It cannot be adjusted horizontally for observation and cannot adapt to complex transportation environments. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a mining intrinsically safe camera for a monorail crane locomotive. The camera head is protected by a shell, thereby protecting the lens. At the same time, the angle of the camera can be adjusted according to the observation direction, thereby adapting to complex transportation environments.

[0005] The utility model is realized through the following technical scheme: a mining intrinsically safe camera for a monorail crane locomotive, comprising a camera and a shell connected to the monorail crane, wherein the camera is detachably connected in the shell, a light-transmitting hole for the camera to shoot is provided on the front end surface of the shell, a transparent baffle is provided in the light-transmitting hole, and the cable of the camera is sealed and passes through the shell.

[0006] When the new type is used, the camera is placed inside the shell to protect the lens, thereby avoiding the problem of reduced clarity or even damage to the lens due to long-term exposure.

[0007] Preferably, the shell includes a cylinder connected to the monorail crane and fixing the camera, a front end cover threadedly connected to the opening of the cylinder, the front end cover is provided with the light-transmitting hole, and the cable seal passes through the bottom of the rear cylinder.

[0008] This preferred solution facilitates installation and removal of the camera in the barrel through the provision of the barrel and the front end cover.

[0009] Preferably, a first limiting surface connected to the end surface of the cylinder is provided in the light-transmitting hole, and a first sealing ring is provided on the first limiting surface.

[0010] In this preferred solution, the sealing connection between the front end cover and the cylinder is achieved by providing the first limiting surface and the first sealing ring.

[0011] Preferably, a second limiting surface is provided in the light-transmitting hole, a sealing gasket is provided between the second limiting surface and the transparent baffle, and a limiting bolt is threadedly connected in the light-transmitting hole to push the transparent baffle onto the sealing gasket.

[0012] This preferred solution limits and fixes the transparent baffle through the provision of the second limiting surface, the sealing gasket, and the limiting bolts. At the same time, the provision of the sealing gasket enables the transparent baffle to seal and block the light-transmitting hole.

[0013] Preferably, the camera is bolted to a fixing seat, and a flange connected to the fixing seat bolts is provided in the cylinder.

[0014] This preferred solution connects the camera to the fixing seat outside the barrel through the setting of the fixing seat and the flange, and then connects to the fixing seat through the flange, thereby avoiding damage to the camera due to small space when the camera is directly connected to the barrel.

[0015] Preferably, a rear end cover covering the bottom of the cylinder is detachably connected to the cylinder body, and a cable connector connected to the cable is provided on the rear end cover.

[0016] In this preferred solution, the connection between the cable connector and the cylinder is achieved by setting the rear end cover.

[0017] Preferably, a fixing part is fixedly connected to the circumferential surface of the cylinder, the fixing part is axially connected to the bracket, the bracket is bolted to the monorail crane, the fixing part is threadedly connected with a fixing bolt that passes through the bracket, the bracket is provided with an arc-shaped long hole for the fixing bolt to pass through, and the head size of the fixing bolt is larger than the width of the arc-shaped long hole.

[0018] When this preferred solution is in use, when the head of the fixing bolt hits the arc-shaped long hole, it plays the role of fixing the fixing part and limiting the rotation of the fixing part relative to the bracket, that is, limiting the rotation of the fixed cylinder and the camera. When the cylinder needs to be rotated, the fixing bolt is rotated, and then the cylinder is rotated to adjust the angle. After that, the fixing bolt is tightened to adjust the camera angle, thereby adapting to complex transportation environments.

[0019] Preferably, a second stud penetrating the bracket is provided on the bottom surface of the fixing member, and a second nut threadedly connected to the second stud and pushed onto the bracket.

[0020] When this preferred solution is in use, the second nut and the second stud are provided to achieve the connection of the fixing seat to the bracket. When the second bolt is pushed onto the bracket, the connection strength between the fixing seat and the bracket is further improved.

[0021] The beneficial effects of the utility model are as follows: by placing the camera inside the shell, the lens is protected to avoid the problem of reduced clarity or even damage to the lens due to long-term exposure; by the arrangement of the barrel and the front end cover, the camera can be easily installed and disassembled in the barrel; by the arrangement of the first limiting surface and the first sealing ring, a sealed connection between the front end cover and the barrel is achieved; when the head of the fixing bolt hits the arc-shaped long hole, it fixes the fixing part and limits the rotation of the fixing part relative to the bracket, that is, limits the rotation of the fixed barrel and the camera. When the barrel needs to be rotated, the fixing bolt is rotated, and then the barrel is rotated to adjust the angle, and then the fixing bolt is tightened to adjust the camera angle, thereby adapting to complex transportation environments.
