Description

Technical Field

[0001] This utility model relates to the field of coal mine transfer machines, specifically, to a transfer machine trough with a cage-type top plate. Background Technology

[0002] In the production process of fully mechanized longwall mining faces in extra-thick coal seams, top coal discharge is the main production step, and the output of the working face is mainly derived from coal discharge. Therefore, coal discharge in fully mechanized longwall mining faces plays a crucial role in the entire coal mining cycle. Researching and developing automated coal discharge technology for fully mechanized longwall mining faces is of great significance for reducing the labor intensity of coal discharge workers, reducing the gangue mixing rate, and improving the top coal extraction rate and mining efficiency. To achieve automated coal discharge, coal flow monitoring equipment needs to be installed at some point on the transfer conveyor. However, it is not feasible to directly install a coal flow monitoring system on the transfer conveyor body, or the installation method poses safety hazards.

[0003] Utility model patent CN222388919U discloses a maintenance trough and screening transfer machine, including a trough body comprising a bottom plate, side plates, a middle plate, a cross plate, and an upper edge. The bottom plate is connected to the bottom of the side plates on both sides. The middle plate is arranged on the inner side wall of the side plates, and the cross plate is arranged on the inner side wall of the side plates on both sides of the middle plate. The bottom plate, side plates, middle plate, and cross plate form a scraper chain transport channel, and the upper edge is provided on the top of the side plates. This maintenance trough and screening transfer machine features a detachable movable edge on the side plates. When maintenance is required, the movable edge can be disassembled to expose the double-chain scraper chain, pressure plate, and bolts on the movable edge for maintenance. After the exposed part is repaired, the equipment is started to move the unrepaired part to the movable edge for maintenance, and this process is repeated until the entire double-chain scraper chain is repaired. Maintenance is convenient and quick. However, the disclosed structure of the central trough and screening transfer machine does not meet the requirements for installing coal quantity monitoring devices, and there are also safety hazards due to the open top of the screening transfer machine. Utility Model Content

[0004] In order to improve the safety of the transfer machine trough when monitoring coal quantity, the technical solution adopted by this utility model is: a transfer machine trough with a cage-type top plate, including a transfer machine trough middle plate, a transfer machine trough side, a cage-type top plate and a coal quantity monitoring device. The sides of the transfer machine trough are arranged on both sides of the middle plate of the transfer machine trough to form a coal conveying channel; The cage-type top plate can be detached and spans the top of the side of the transfer machine trough to protect the top of the coal conveying channel; The coal quantity monitoring device is suspended inside the cage-type roof slab and is used to monitor the amount of coal unloading in the coal conveying channel. The bottom of the cage-type roof slab is provided with a monitoring channel for the coal quantity monitoring device to monitor.

[0005] Based on the above, in order to facilitate the connection between the cage-type top plate and the side of the transfer machine trough, increase the support area, and ensure structural stability, the top of the side of the transfer machine trough is provided with an upper folded edge for connecting the cage-type top plate, and the bottom of the cage-type top plate is detachably connected to the upper folded edge by bolts.

[0006] Based on the above, in order to improve the protection capability and avoid damage to the coal quantity monitoring device, and at the same time, to facilitate the coal quantity monitoring device to monitor the coal quantity, the cage-type top plate includes a pair of connecting plates, a pair of span plates, several side rails, an angle steel upper frame, and several crossbeams. A pair of connecting plates and a pair of cross plates together form a lower frame, and the upper frame of the angle steel and several crossbeams together form an upper frame. The upper frame and the lower frame are connected by several side rails. The coal quantity monitoring device is suspended in the middle of the crossbeam.

[0007] That is, a cage-like roof can be used as a protective cage to suspend the coal quantity monitoring device directly above the coal conveying channel, while maintaining a certain distance between the device and the top of the channel. This ensures that the monitoring device can perform scanning and monitoring along the width of the channel while also being protected by the cage-like roof.

[0008] Based on the above, in order to avoid interference with the coal quantity monitoring device's scanning monitoring along the width of the coal conveying channel, a monitoring channel is formed between the gaps between the two cross plates for the coal quantity monitoring device to monitor.

[0009] Based on the above, in order to increase the structural emphasis and stability of the top of the cage-type capping plate, several vertical beams are also provided inside the upper frame of the angle steel, and the vertical beams are arranged perpendicularly to the horizontal beams.

[0010] Based on the above, in order to facilitate installation and disassembly, the connecting plate is provided correspondingly to the upper folded edge, and the connecting plate and the upper folded edge are detachably connected by bolts.

[0011] Based on the above, the coal quantity monitoring device includes a camera and a laser, which are suspended directly above the coal conveying channel.

[0012] This utility model has substantial features and advancements compared to existing technologies. Specifically, it provides a transfer conveyor trough with a cage-type top plate. By suspending the coal quantity monitoring device inside the cage-type top plate, and with the cage-type top plate detachably spanning the top of the side of the transfer conveyor trough, the top plate can protect the top of the coal conveying channel and the coal quantity monitoring device, ensuring its safe suspension directly above the channel. This prevents objects from falling into the transfer conveyor trough and from damaging the coal quantity monitoring device. It allows the coal quantity monitoring device to safely monitor the amount of coal unloading within the conveying channel, thus improving the safety of the transfer conveyor trough when monitoring coal quantity.

[0013] Furthermore, by setting a connecting plate at the bottom of the cage-type top plate and setting an upper folded edge connected to the connecting plate at the top of the side of the transfer machine trough, the contact area between the cage-type top plate and the side of the transfer machine trough is increased, thereby increasing the structural stability.

[0017] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0018] Example 1 This embodiment provides a transfer machine tank, such as... Figure 1 and Figure 2 As shown, the system includes a transfer trough center plate 1, transfer trough side panels 2, a cage-type roof plate, and a coal quantity monitoring device 3. The transfer trough side panels 2 are located on both sides of the transfer trough center plate 1 to form a coal conveying channel.

[0019] The cage-type top plate is detachably mounted across the top of the transfer machine trough side 2 to protect the top of the coal conveying channel. The coal quantity monitoring device 3 is suspended inside the cage-type top plate to monitor the amount of coal unloading in the coal conveying channel.

[0020] The bottom of the cage-type roof slab is provided with a monitoring channel for the coal quantity monitoring device 3 to monitor.

[0021] Specifically, in order to improve protection capabilities and prevent damage to the coal quantity monitoring device, and also to facilitate the monitoring of coal quantity by the coal quantity monitoring device, in this embodiment, as follows: Figure 2 As shown, the cage-type top plate includes a pair of connecting plates 5, a pair of span plates, several side rails 6, an angle steel upper frame 7, several horizontal beams 9 and several vertical beams 8.

[0022] A pair of connecting plates 5 and a pair of spanning plates together form a lower frame. The upper frame 7 of the angle steel, together with several horizontal beams 9 and several vertical beams 8, forms an upper frame. The upper frame and the lower frame are connected by several side rails 6. The coal quantity monitoring device 3 is suspended in the middle of the horizontal beams 9. The vertical beams 8 are arranged perpendicularly to the horizontal beams 9.

[0023] Specifically, the coal quantity monitoring device includes a camera and a laser, which are suspended directly above the coal conveying channel.

[0024] That is, the camera and laser in the coal quantity monitoring device need to be installed directly above the coal flow. Therefore, the entire width of the transfer machine trough needs to be scanned, which requires the entire width of the top plate to be opened, so that the coal flow is completely exposed directly below the camera and laser.

[0025] In this embodiment, a cage-like roof slab can be used as a protective cage to suspend the coal quantity monitoring device directly above the coal conveying channel, while maintaining a certain distance between the device and the top of the channel. This ensures that the coal quantity monitoring device can perform scanning and monitoring along the width of the channel while also being protected by the cage-like roof slab.

[0026] Example 2 This embodiment provides a transfer machine trough, which differs from Embodiment 1 in that, in this embodiment, to facilitate the connection between the cage-type top plate and the side of the transfer machine trough, increase the support area, and ensure structural stability, an upper folded edge 11 for connecting the cage-type top plate is provided at the top of the side 2 of the transfer machine trough. Specifically, the connecting plate 5 in the cage-type top plate is correspondingly provided with the upper folded edge 11, and the connecting plate 5 and the upper folded edge 11 are detachably connected by bolts.

[0027] Example 3 This embodiment provides a transfer machine trough, which differs from Embodiment 1 in that, in this embodiment, to avoid interference with the coal quantity monitoring device's scanning and monitoring along the width of the coal conveying channel, a monitoring channel is formed between a pair of cross plates for the coal quantity monitoring device to monitor.

[0028] Specifically, for ease of distinction, the spans can be divided into front spans 4 and rear spans 10 based on their distribution location. The upper frame of the angle steel can be made by splicing and welding four angle steels together. Several side rails are arranged on the four vertical surfaces of the cage-type capping slab. Several horizontal beams and several vertical beams overlap vertically, with horizontal beam 9 on top and vertical beam 8 on the bottom.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
