Description

Technical Field

[0001] The present application relates to the technical field of tank cages, and in particular to a tank cage loading system. Background Art

[0002] A cage is a mine hoisting container used to transport personnel, ore, equipment, and materials, and is one of the three major modes of transportation in mines. Cage hoisting is a significant safety risk factor in coal mine production, and overloading and exceeding limits are key factors in causing accidents. In minor cases, this can trigger the hoisting equipment's overload protection, causing the cage to stop operating and reducing hoisting efficiency. In more serious cases, it can cause irreversible damage to the cage's wire rope or the motor that pulls the wire rope, leading to rope breakage, cage falls, cage stalls, and other safety accidents.

[0003] At present, cage fall arresters are widely used in coal mine cage hoisting systems, but cage fall arresters are not foolproof. Some coal mines have even experienced cage falling accidents when conducting safety tests on fall arresters, failing to reduce the probability of risks from the source. Utility Model Content

[0004] The present application provides a cage loading system, which can detect the installation status of the mine car before the mine car enters the cage, thereby ensuring the safety of the cage and the mine car loading and lifting system.

When the human detection unit detects the presence of a person around the weight detection unit, the control circuit controls the first alarm unit to issue an alarm signal.

[0011] As a possible implementation, the human body detection unit is configured as an image processing device whose image is located above the path; or, the human body detection unit is configured as an infrared detector whose image is located above the path.

[0023] Cage transport is one of the three major modes of transportation in coal mines. Overload and over-limit protection for mine car cages means that when loading materials and equipment into the auxiliary shaft cage, the weight and dimensions of the cargo entering the cage must not exceed the maximum load capacity of the cage hoist, and the dimensions of the cargo loaded on the mine car must not exceed the maximum volumetric dimensions of the cage.

[0024] When loading materials or equipment in the cage of the coal mine auxiliary shaft, if the overload and overlimit monitoring of the cargo loaded on the mine car entering the cage is not carried out, and the cargo loaded on the mine car is directly loaded into the cage, the loading mass may exceed the maximum traction force of the wire rope motor of the lifting cage. At the very least, it will cause the overload protection of the lifting equipment, causing the cage to stop running and reduce the lifting efficiency; at worst, it will cause irreversible damage to the wire rope of the traction cage or the motor of the dragging wire rope, resulting in safety accidents such as rope breakage, cage falling, and cage stalling.

[0025] At present, cage fall arresters are widely used in coal mine cage hoisting systems, but cage fall arresters are not foolproof. Some coal mines have even experienced cage falling accidents when conducting safety tests on fall arresters, failing to reduce the probability of risks from the source.

[0026] Based on this, in order to reduce the risk of safety accidents in the cage lifting link, the present application provides a cage loading system, which can detect the installation status of the mine car before the mine car enters the cage, thereby ensuring the safety of the cage and the mine car loading lifting system.

[0027] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the principle of a cage loading system according to one embodiment of the present application. Figure 2 : is a structural schematic diagram of a cage loading system according to an embodiment of the present application. The present application provides a cage loading system, which may include a mine car 10, a cage 20, a pusher 30, a safety detection unit 40, and a control circuit 50. The interior of the cage 20 defines a loading space for loading the mine car 10. The pusher 30 is provided on the mine car 10 and is used to provide a driving force for the mine car 10 to move. The safety detection unit 40 is provided on the path of the mine car 10 moving to the loading space and is used to detect the safety status of the mine car 10. The input end of the control circuit 50 is electrically connected to the safety detection unit 40, and the output end of the control circuit 50 is electrically connected to the pusher 30. The control circuit 50 is used to control the start and stop of the pusher 30 according to the safety status of the mine car 10.

[0029] The mine cart 10 is used to load and transport goods, personnel, and materials. A pusher 30 provides power to the mine cart 10, propelling it into and out of the loading space. The cage 20 is a mine hoisting container used to transport personnel, ore, equipment, and materials. Its function is similar to an elevator, lifting and lowering personnel or cargo within the mine.

[0030] In this embodiment, a safety detection unit 40 is provided along the path of the mine car 10 as it moves toward the loading space, and is used to detect the safety status of the mine car 10. A control circuit 50 is electrically connected to the safety detection unit 40 and the pusher 30, and is used to control the start and stop of the pusher 30 based on the safety status of the mine car 10.

[0031] Thus, before the mine car 10 enters the loading space, the safety detection unit 40 can perform a safety check on the mine car 10. If the safety check passes, the control circuit 50 can control the driving part of the mine car 10 (i.e., the pusher 30) to move the mine car 10 into the loading space. If the safety check fails, the control circuit 50 can control the pusher 30 to restrict the movement of the mine car 10, preventing it from entering the loading space. This eliminates safety hazards at the source and further improves the safety of the cage 20 during operation.

[0032] In some embodiments, the safety detection unit 40 includes a weight detection unit 42 for detecting the total weight of the mining cart 10 and the cargo inside the mining cart 10. The control circuit 50 is electrically connected to the weight detection unit 42 and controls the start and stop of the pusher 30 according to the total weight.

[0033] In this embodiment, a weight detection unit 42 is installed along the path of the mine car 10 toward the loading space. As the mine car 10 moves toward the cage 20, it passes through the weight detection unit 42. While passing through the weight detection unit 42, the weight detection unit 42 measures the total weight of the mine car 10 and its cargo, generates a voltage signal, and calculates the total weight of the mine car 10 and its cargo.

[0034] The control circuit 50 is electrically connected to the weight detection unit 42 and is capable of receiving the total weight value signal transmitted by the weight detection unit 42 and determining whether the total weight value exceeds a set weight threshold. If the total weight value exceeds the set weight threshold, the control circuit 50 sends an overload signal back to the pusher 30, causing the pusher 30 to stop operating. The overloaded mine cart 10 cannot enter the cage 20, thereby improving the safety of the cage 20 during operation. If the total weight value does not exceed the set weight threshold, the control circuit 50 sends a normal signal back to the pusher 30, causing the pusher 30 to continue operating and the mine cart 10 enters the cage 20.

[0035] In some specific embodiments, the weight detection unit 42 may be disposed on the mine car 10 to directly weigh the weight of the mine car 10 and the cargo inside the mine car 10 and transmit the weight to the control circuit 50 via wireless communication.

[0036] In some other specific embodiments, the cage loading system may further include a transport track 60, which is used to guide the mine car 10 to the loading space. The weight detection unit 42 is set on the transport track 60. The mine car 10 must pass through the weight detection unit 42 during transportation, and no missed detection will occur.

[0037] In addition, compared with the embodiment in which the weight detection unit 42 is directly set on the mine car 10, this embodiment has the following two advantages. First, there is no need to set a weight detection unit 42 separately on each mine car 10, which can reduce the cost of use. Second, the weight detection unit 42 itself is set on the transport track 60 that is stationary relative to the mine car 10, which can facilitate the use of a lower-cost and more reliable wired connection method to electrically connect with the control circuit 50.

[0038] Furthermore, the weight detection unit 42 may be further configured as a track scale laid on the transport track 60 .

[0039] Track scales are instruments used to measure the weight of trucks on rails. They include static track scales and dynamic track scales. Static track scales are used to measure the weight of trucks at rest. Dynamic track scales are used to measure the weight of trucks in motion.

[0040] In this embodiment, a dynamic track scale is preferably used to reduce the impact of safety detection on the operation of the mine car 10. In this way, when a non-overloaded mine car 10 passes through the dynamic track scale at a certain speed, the control circuit 50 will not restrict it, and the mine car 10 can smoothly enter the loading space without stopping, reducing the impact on the operation of the mine car 10. Only when an overloaded mine car 10 passes through the dynamic track scale will the control circuit 50 restrict it.

[0041] In some embodiments, the cage loading system can also reduce human interference when detecting the weight of the mining vehicle 10 and the cargo it carries, and improve the safety and accuracy of the detection.

[0042] Specifically, the cage loading system may further include a first alarm unit 70 and a human body detection unit 80. The first alarm unit 70 is used to send an alarm signal. The human body detection unit 80 is used to detect whether there is a person around the weight detection unit 42.

[0043] The input end of the control circuit 50 is electrically connected to the human body detection unit 80, and the output end of the control circuit 50 is electrically connected to the first alarm unit 70. When the human body detection unit 80 detects that there is a person around the weight detection unit 42, the control circuit 50 controls the first alarm unit 70 to send an alarm signal.

[0044] In this embodiment, the human detection unit 80 is used to detect whether there is a person around the weight detection unit 42. When the human detection unit 80 detects the presence of a person around the weight detection unit 42, it sends an electrical signal to the control circuit 50. After receiving the signal, the control circuit 50 controls the alarm to start. In this way, the weighing area of ​​the mining vehicle 10 can be restricted to people, preventing unauthorized people from entering, ensuring the accuracy of the detection data, and warning unauthorized people to leave, thereby improving the safety during detection.

[0045] In some optional embodiments, the human body detection unit 80 is further configured as an image processing device whose image is located above the path.

[0046] When the mining vehicle 10 passes the weight detection unit 42, the image processing device collects images of the environment around the weight detection unit 42. The image processing determines whether there are people.

[0047] In some optional embodiments, the human body detection unit 80 can be further configured as an infrared detector whose image is located above the path, that is, the principle of infrared detection is used to identify whether there is a person around the weight detection unit 42.

[0048] In some optional embodiments, the first alarm unit 70 is further configured as one or more of an audible alarm device 72, a light alarm device 74, and a display alarm device 76. The audible alarm device 72 can emit an audible alarm, and the light alarm device 74 can emit a flashing light alarm. The display alarm device 76 can display an alarm signal on a related display screen. During use, one or more of the above three methods can be flexibly selected, and all combinations are not listed here.

[0049] In some embodiments, the safety detection unit 40 may further include a shape detection unit 44 for detecting the size of the cargo carried by the mining vehicle 10. The control circuit 50 is electrically connected to the shape detection unit 44 and controls the start and stop of the pusher 30 according to the size of the cargo.

[0050] In actual use, the mine car 10 may be loaded with goods that exceed the frame of the mine car 10. If these goods exceed a certain range, they will interfere with the cage 20 when entering the loading space, and may even cause safety accidents such as falling off or dropping. Therefore, it is necessary to inspect the appearance of the goods during the safety status inspection to ensure that the goods meet the loading requirements.

[0051] In this embodiment, the shape detection unit 44 is provided on the path of the mine car 10 moving toward the loading space. When the mine car 10 moves toward the cage 20, it needs to pass through the shape detection unit 44. When passing through the shape detection unit 44, the shape detection unit 44 can detect the dimensions (including length, width, and height) of the cargo.

[0052] The control circuit 50 is electrically connected to the shape detection unit 44 and is capable of receiving the cargo size signal conveyed by the shape detection unit 44 and determining whether the cargo size exceeds a set size threshold. If the cargo size exceeds the set size threshold, the control circuit 50 transmits an overload signal back to the pusher 30, causing the pusher 30 to stop operating and prevent the mine cart 10 from entering the cage 20, thereby improving the safety of the cage 20 during operation. If the cargo size does not exceed the set size threshold, the control circuit 50 transmits a normal signal back to the pusher 30, causing the pusher 30 to resume operation and allow the mine cart 10 to enter the cage 20.

[0053] It should be noted that the size of the goods will be measured by multiple specific parameters (including length, width, and height)

[0054] When the control circuit 50 determines whether the size of the goods exceeds the set size threshold, if all parameters do not exceed the set size threshold, it determines that the size of the goods does not exceed the set size threshold; otherwise, it determines that the size of the goods exceeds the set size threshold.

[0055] Furthermore, the shape detection unit 44 is further configured as an image acquisition and processing device located above and / or to the side of the path.

[0056] When the mining car 10 passes the shape detection unit 44, it captures images of the cargo to be loaded into the cage 20. After image processing, the cargo's dimensions are determined. Specifically, an image acquisition and processing device located above the path can capture images from a bird's-eye view to determine the cargo's length and width. An image acquisition and processing device located to the side of the path can capture images from a side-on view to determine the cargo's length and height.

[0057] In some embodiments, the cage loading system may further include a second alarm unit 90 configured to issue an alarm signal. The output terminal of the control circuit 50 is electrically connected to the second alarm unit 90 , and the control circuit 50 controls the second alarm unit 90 to issue an alarm signal based on the safety status of the mining vehicle 10 .

[0058] For example, when the weight detection unit 42 detects that the total weight of the mine car 10 and the cargo in the mine car 10 exceeds the set threshold, on the one hand, the control circuit 50 controls the pusher 30 to stop so that the overloaded mine car 10 cannot enter the cage 20; on the other hand, the control circuit 50 controls the second alarm unit 90 to send an alarm signal to remind the staff to adjust the cargo weight in time.

[0059] For another example, when the shape detection unit 44 detects that the cargo in the mine car 10 exceeds the limit, on the one hand, the control circuit 50 controls the pusher 30 to stop so that the overloaded mine car 10 cannot enter the cage 20; on the other hand, the control circuit 50 controls the second alarm unit 90 to send an alarm signal to remind the staff to adjust the shape of the cargo to avoid exceeding the limit or height.

[0060] Furthermore, the second alarm unit 90 and the first alarm unit 70 can be configured as the same device or as different devices. When the second alarm unit 90 and the first alarm unit 70 are configured as different devices, the second alarm unit 90 can also be configured as one or more of a sound alarm device, a light alarm device, and a display alarm device.

[0061] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present application have been shown and described in detail herein, many other variations or modifications that are consistent with the principles of the present application can be directly determined or derived from the contents disclosed herein without departing from the spirit and scope of the present application.
