Description

Technical Field

[0001] The utility model relates to a safety device, in particular to a tank ear and tank channel spacing sensing device suitable for a tank cage shaft. Background Art

[0002] According to the requirements of the coal mine safety production regulations, mines equipped with cages should regularly measure the distance between the cage ears and the cage channel, and the cage channel should be replaced in time when the wear is too large. The current measurement method is to conduct on-site measurements manually on the cage. This measurement method is time-consuming and labor-intensive, and requires workers to climb up and down the cage, which is very inconvenient to operate.

[0003] Currently, a utility model patented with patent publication number CN201520582U discloses a cage lug arrangement for a hoisting system. The lugs are arranged in a diagonally staggered arrangement, with a pair of lugs located diagonally on two opposing sides of the cage, on a diagonal line on each side. The lugs on the two opposing sides are located on two different diagonals. This structural arrangement constrains the cage only at diagonal positions when entering and exiting the tankway, reducing cage constraints and effectively preventing cage jams. Its simple structure can effectively reduce maintenance, improve hoisting efficiency, and thus enhance coal mine production benefits.

[0004] From the above disclosed technical content, it can be seen that as an existing technology, the utility model with announcement number CN201520582U directly rubs the tank channel through the tank ear, which accelerates the wear of the tank channel and the tank ear. More frequent measurements are required to ensure the safety of the tank cage lifting, which is not very convenient to use. Utility Model Content

The end of the protective plate opening push rod is installed on the upper layer, and the telescopic end of the protective plate opening push rod passes through the preset opening at the front of the safety shell to press against the protective plate. A glass window is installed on the surface of the safety shell to which the protective plate is attached, and a camera and a laser emitter are installed on the inside of the glass window through a bracket. The camera and the laser emitter are attached to the glass window, and a control panel is fixedly installed behind the camera and the laser emitter. The circuit of the control panel is connected to the dispatching room through the circuit interface.

In the description of this application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0021] The following describes the tank ear and tank channel spacing sensing device of the utility model applicable to the tank cage shaft with reference to the accompanying drawings.

[0022] In Example 1 of the present application, Figures 1 to 3 As shown, the tank ear and tank channel spacing sensing device suitable for a tank cage shaft (hereinafter referred to as "the present invention") includes a tank ear bottom plate 1, a tank ear guide wheel 2, a spacing measuring component 3, a safety shell 3-1, a protective plate 3-2, a protective plate opening push rod 3-3, a glass window 3-4, a camera 3-5, a laser emitter 3-6, a control panel 3-7, a line interface 3-8, a transverse movement control screw 3-9, and a tank channel groove 4. A tank channel groove 4 is provided vertically up and down on one side of the tank ear bottom plate 1, and the tank ear guide wheel 2 is respectively installed on three sides of the tank channel groove 4. The spacing measuring component 3 is fixedly installed on the surface of the tank ear bottom plate 1 on the side of the tank ear guide wheel 2. The spacing measuring component 3 also includes a safety shell 3-1, and the safety shell 3-1 faces the side of the tank channel. The protective plate 3-2 is installed through a spring shaft, and the interior of the safety shell 3-1 is divided into two layers, the upper and lower layers, by a partition. The end of the protective plate opening push rod 3-3 is installed on the upper layer through a shaft or a bracket, and the telescopic end of the protective plate opening push rod 3-3 passes through the preset opening on the front of the safety shell 3-1 to press against the protective plate 3-2. A glass window 3-4 is installed on the surface of the safety shell 3-1 to which the protective plate 3-2 is attached, and a camera 3-5 and a laser emitter 3-6 are installed on the inside of the glass window 3-4 through a bracket. The camera 3-5 and the laser emitter 3-6 are attached to the glass window 3-4, and a control board 3-7 is fixedly installed behind the camera 3-5 and the laser emitter 3-6. The line of the control board 3-7 passes through the line interface 3-8 to be connected to the dispatching room.

[0023] The utility model with the utility model announcement number CN201520582U discloses a tank ear arrangement structure of a tank cage in a lifting system (hereinafter referred to as "this patent"). This patent directly rubs the tank channel through the tank ears, which accelerates the wear of the tank channel and the tank ears. More frequent measurements are required to ensure the safe lifting of the tank cage, which is not very convenient to use. The present invention adds a spacing measurement component 3 next to the tank ear guide wheel 2. Through laser and visual positioning, safety measurements no longer need to be performed manually on site, effectively reducing labor intensity and making safety measurement work simple.

[0024] The structure of the second embodiment is basically the same as that of the first embodiment, except that Figure 3 and Figure 4 As shown, the bracket for installing the camera 3-5 and the laser emitter 3-6 moves horizontally inside the safety shell 3-1 through a slide rail. A through hole is opened on the surface of the safety shell 3-1 and a horizontal movement control screw 3-9 is installed through a shaft sleeve. The horizontal movement control screw 3-9 is screwed to the bracket for installing the camera 3-5 and the laser emitter 3-6.

[0025] To further optimize the performance of this application, the protective plate 3-2 is equipped with a rubber pad facing the glass window 3-4 to protect it. To allow staff in the dispatch room to more accurately assess the wear status, the glass window 3-4 is marked with a scale. The protective plate opening push rod 3-3 has a built-in motor, which, through a screw, drives a telescopic rod screwed onto the screw to extend and retract within the sleeve of the protective plate opening push rod 3-3.

[0026] Install the lug-to-way distance sensing device suitable for the cage shaft and connect the appropriate wiring. During installation, first measure the distance between the canal and lug. Once the distance meets the requirements, use the lateral control screw 3-9 to align the port of the laser transmitter 3-6 with the canal edge. Ensure the laser spot is no more than 15 millimeters from the lug pulley edge, and the device is ready for use.

[0027] When the utility model is in use, the specific operations are as follows:

[0028] During use, the staff in the dispatch room issues instructions through the computer, and the control panel 3-7 controls the motor in the protective plate opening push rod 3-3 to drive the screw on the rotating shaft. The rotation of the screw drives the telescopic end of the protective plate opening push rod 3-3 to extend, thereby lifting the protective plate 3-2. At this time, the camera 3-5 and the laser emitter 3-6 in the glass window 3-4 are facing the guide groove or guide column of the pipeline. The laser emitter 3-6 projects a laser point on the surface of the tank channel, and the camera 3-5 takes a picture. At this time, it can be observed whether the wear position of the tank channel reaches the laser point. If it reaches the laser point, it means that the distance between the tank channel and the tank ear has exceeded the safety limit and needs to be replaced.

[0029] In summary, the embodiment of the utility model is suitable for the tank ear and tank channel spacing sensing device of the tank cage shaft. By adding a spacing measurement component 3 next to the tank ear guide wheel 2, laser and visual positioning are used, and then the wear amount within the safety range is reserved. Each time, the wear condition can be determined by checking the laser point position through cameras 3-5. The wear degree of the tank channel can be measured directly by a human in the dispatching room with one click, and the spacing between the tank ear and the tank channel can be measured more simply.
