Description

Technical Field

[0001] The utility model belongs to the field of inclined lane winch rail transportation, in particular to a system for detecting whether a mine car is running away in coal mine production. Background Art

[0002] The mine inclined lane is the main channel for transporting materials in various mining areas of the mine. It has a large transportation volume, a large number of operating staff, and a complex environment. During the operation of the winch, the driver generally operates the winch by watching and listening to the signals, while the signals, yard switches, and car barriers are operated by the hookmen in each yard. Inclined shaft runaway refers to an accident in which the mine car loses control and falls along the inclined shaft when the vehicle is lifted or lowered in the inclined shaft. When working underground, the hookman makes a mistake in removing the hook or the rope breaks or the hook is unhooked, causing the mine car to run away. It is necessary to quickly and accurately determine whether the mine car has run away, and provide trigger signals for subsequent response measures such as alarm, locking and stopping, and starting the anti-runaway device. Mine inclined lanes are frequent places for mine transportation accidents, accounting for a large proportion of sporadic mine accidents each year.

[0003] At present, manufacturers use three methods to monitor sports cars: manual video surveillance, comparing the position of the mine car with the shuttle car position, and measuring the speed of the mine car with the shuttle car speed.

[0004] Advantages of manual video surveillance: The signal is transmitted wirelessly, which solves the problem of cable connection of mobile devices and is practical for regular use; Disadvantages: It places high demands on the winch driver, who is required to concentrate highly and continuously observe the on-site video images during the entire transportation process, and to respond immediately and take countermeasures in the event of a sports car accident; this is difficult to do manually.

[0005] Advantages of comparing the mine car positioning with the shuttle car position: the signal is transmitted wirelessly, which solves the problem of cable connection of mobile equipment and is practical for regular use; Disadvantages: monitoring equipment needs to be installed on the last mine car, but there are a large number of mine cars in actual transportation, and any mine car may become the last one, which makes it difficult to use on a regular basis.

[0006] The advantages of measuring the speed of the mine car compared to the shuttle car speed: the speed measuring device is installed in the transport lane, which solves the problem of cable connection of mobile equipment and has the practicality of normal use; Disadvantages: speed measuring devices need to be arranged in many positions in the transport lane, but it is impossible to monitor the sports car without blind spots during the entire transportation process; the implementation cost is high and the maintenance volume is large.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0026] The utility model discloses a system for detecting whether a mine car is running out of track in coal mine production. Figure 1 As shown, a plurality of mine carts are connected in sequence, and the mine cart at the front is connected to a shuttle car, which is used to drive the mine cart forward.

[0027] The system includes: acquisition module, processing module and alarm module.

[0028] The acquisition module is installed on the rear side of the shuttle car, close to the frontmost mine car. The acquisition module is installed close to the top of the shuttle car. The shooting angle of the acquisition module is 45 degrees downward and it shoots from the front. The acquisition module is used to collect photos of all mine cars in motion behind the shuttle car.

[0029] The processing module is used to receive the collected photos from the collection module, and process them to obtain the length of the rail between two adjacent mine cars. When the length of the rail is greater than a predetermined value, an alarm signal is sent.

[0030] The alarm module is used to receive an alarm signal and send an action signal to multiple alarms arranged along the lane, so that the multiple alarms start to alarm.

[0031] The acquisition module is a camera, which is installed on the top of the shuttle car through a bracket. The bracket includes a left vertical plate 1, a right vertical plate 2, and a fixed plate 3 fixedly connected to the upper ends of the left vertical plate 1 and the right vertical plate 2. The lower end of the left vertical plate 1 is fixedly connected to the rotating shaft bearing on the left side of the shuttle car, and the lower end of the right vertical plate 2 is fixedly connected to the rotating shaft bearing on the right side of the shuttle car. The fixed plate 3 is located above the shuttle car, and a rotating rod is horizontally installed on the rear side of the fixed plate 3.

[0032] The bracket further includes a bearing plate 4 , a positioning rod 5 and a protective cover 6 .

[0033] The bearing plate 4 is tilted, and a bearing hole is horizontally opened on the bearing plate 4. The bearing hole is used for the rotation rod to pass through, and the bearing plate 4 is fixed on the fixing plate 3, so that the bearing plate 4 can rotate around the fixing plate 3.

[0034] One end of the positioning rod 5 is fixed to the lower side of the fixing plate 3 and at a front position, and the other end of the positioning rod 5 is fixedly connected to the lower end of the supporting plate 4. The positioning rod 5 is used to pull the supporting plate 4 and make the supporting plate 4 at a 45 degree tilt angle.

[0035] The protective cover 6 is a hollow cylindrical structure, and is fixedly connected to the rear side of the carrying plate 4 . The protective cover 6 is used to fix and protect the camera.

[0036] A support plate 7 is also fixedly connected inside the protective cover 6 , and two ends of the support plate 7 are respectively fixedly connected to two sides of the inner wall of the protective cover 6 , and the support plate 7 is used to fix the camera.

[0037] Each mine car on the rear side of the shuttle car is connected to each other, so that the shuttle car can drive all the mine cars to move. Under normal circumstances, no rails can be seen between two adjacent mine cars or the length of the rails is very small. Once the rails are seen or the length of the rails seen is greater than a predetermined value, that is, the rails between two adjacent mine cars can be seen from the taken photos or the length of the detected rails is greater than a predetermined value, it means that a runaway car has occurred, and the shuttle car is driving in front, and it is impossible to quickly distinguish whether a runaway car has occurred. Therefore, the utility model collects photos of the mine cars and identifies the length of the rails in the photos. Once the length of the identified rails exceeds the predetermined value, it means that a runaway car has occurred. At this time, an alarm is sounded, which can be heard by the driver and personnel along the line, and the runaway car is handled, and the car is automatically locked and stopped immediately.

[0038] In the photographs taken, the rails of the mine cars that did not run away only appear in the front side of the shuttle car or the rear side of the last mine car. Therefore, the requirements for the collected photos are very high. It is necessary to ensure that each mine car is photographed while ensuring that the rails in front of the shuttle car and the rails on the rear side of the last mine car are not photographed. Therefore, the utility model fixes and adjusts the installation position of the camera by setting a bracket.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
