Description

Technical Field

[0001] This utility model relates to the field of scraper conveyors for underground fully mechanized mining faces in coal mines, specifically to an inclined pull-out skylight chute suitable for narrow roadways. Background Technology

[0002] In fully mechanized longwall mining faces in coal mines, the open-slot design of the scraper conveyor in the roadway is crucial. This open structure allows for easy observation of the scraper chain's bottom chain operation and troubleshooting during roadway cleaning and maintenance after a period of operation, ensuring efficient production. Generally, observing the bottom chain operation requires fully removing the intermediate insert plate, which is approximately 1200-1800mm long and can only be removed horizontally. This necessitates considerable horizontal space. However, due to limited working space in some roadways, only a small portion of the intermediate insert plate can be removed, limiting observation of the bottom chain and rendering it ineffective. In situations with limited horizontal space, fully removing the intermediate insert plate requires consideration of either a vertical or oblique approach. Due to the limitations of the side plates, the intermediate insert plate cannot be removed vertically; only an oblique approach can be considered. To ensure the intermediate insert plate can be fully withdrawn at an angle, the width of the side plate of the skylight slot needs to be greater than the notch of the insert plate, and a certain height is also required in the vertical direction to form a large opening space. Furthermore, the skylight slot insert plate and the upper flange are generally separate structures. Considering the vertical height requirement when the intermediate insert plate needs to be withdrawn at an angle, the position of the upper flange affects the angled withdrawal of the intermediate insert plate. After the skylight slot insert plate is withdrawn, since the side plate lacks an observation window, the operation of the bottom chain can only be observed through the opening in the side plate of the intermediate insert plate, and this opening is small, making it impossible to clean accumulated materials or maintain the bottom chain. In summary, under the limited working space of the ground section of the scraper conveyor in the roadway, the skylight slot generally presents three problems: 1. The intermediate insert plate cannot be withdrawn due to space constraints, limiting the observation of the bottom chain operation; 2. If the intermediate insert plate assembly needs to be withdrawn at an angle, the position of the upper flange needs to be adjusted, which is not possible with the general skylight slot structure; 3. The observation window on the side plate of the general skylight slot is small, limiting the observation range and preventing the cleaning of accumulated materials. Summary of the Invention

[0003] In light of the above, the designer proposes this utility model: a technical solution for a slanted-out skylight slot in a transfer machine. This utility model solves the problem of limited working space in roadways preventing the horizontal removal of the insert plate. It is suitable for the landing section of narrow roadways, and its structure allows for observation, cleaning of accumulated materials, and maintenance of the scraper chain. This slanted-out skylight slot in the transfer machine has a simple and robust structure, is easy to manufacture, and is economical.

[0004] To achieve the above objectives, this utility model provides a slanted drawer type skylight slot for a transfer machine. The overall structure includes: skylight slot body 1, baffle assembly 2, fixing pin 3, insert plate assembly 4, bolt assembly 5, upper wing plate 11 of skylight slot body, upper wing plate 41 of insert plate assembly, middle insert plate 42, large upright plate 43, side plate 12, upper connecting plate 21, small upright plate 22, and lower connecting plate 23. The insert plate assembly 4 is fixedly connected to the skylight slot body 1 and baffle assembly 2 by fixing pin 3; the baffle 2 is fixedly connected to the insert plate assembly 4 and skylight slot body 1 by fixing pin 3 and bolt assembly 5.

[0005] Furthermore, in the aforementioned slanted drawer type skylight slot of the transfer machine, the baffle 2 and the insert plate assembly 4 are connected to the skylight slot body 1 through the fixing pin 3 and the bolt assembly 5 to form the skylight slot assembly structure.

[0006] Furthermore, in the aforementioned type of oblique-extraction skylight slot for a transfer machine, in order to minimize the horizontal space required for oblique extraction, the upper wing plate 11 of the skylight slot body needs to be welded in sections.

[0007] Furthermore, in the aforementioned inclined pull-out skylight slot of the transfer machine, the insert plate assembly 4 is an integral assembly welded together from the middle insert plate 42, the large vertical plate 43, and the upper wing plate 41 of the insert plate assembly, and is indivisible; the baffle assembly 2 is welded together from the upper connecting plate 21, the lower connecting plate 23, and the small vertical plate 22, and the upper connecting plate 21 and the lower connecting plate 23 are provided with round holes and are connected to the skylight slot body 1 and the insert plate assembly 4 through bolt assembly 5.

[0008] Furthermore, in the aforementioned slanted drawer type skylight slot of the transfer machine, the side plate 12 of the skylight slot body 1 is provided with a large notch to allow the insert plate assembly 4 to be smoothly pulled out and the baffle assembly 2 to be installed.

[0009] Furthermore, in the aforementioned slanted pull-out skylight slot of the transfer machine, when it is necessary to observe and maintain the skylight slot, it is necessary to first pull out the fixing pin 3, then remove the baffle assembly 2, and then pull out the insert plate assembly 4 obliquely upward or horizontally.

[0010] As can be seen from the above, the inclined drawer type skylight slot of the transfer machine of this utility model has the following advantages and features:

[0011] 1. This utility model relates to a slanted pull-out skylight slot for a transfer machine, wherein the insert plate assembly 4 can be pulled out horizontally or obliquely upward according to the actual situation, which solves the problem that the insert plate cannot be pulled out horizontally due to the limited working space in the tunnel.

[0012] 2. The present invention provides a slanted drawer type skylight slot for a transfer machine. After the baffle assembly 2 and the insert plate assembly 4 are successfully disassembled, the accumulated materials can be observed and cleaned more clearly, improving work convenience and saving time and effort.

[0013] 3. This utility model provides a slanted drawer type skylight slot for a transfer machine. When maintenance of the scraper chain is required, the large opening space facilitates maintenance, reduces the labor intensity of miners, lowers operational risks, and avoids safety accidents during coal mine mining.

[0023] like Figures 1-5 As shown, the overall structure of a slanted drawer type skylight slot for a transfer machine according to this utility model includes: skylight slot body 1, baffle assembly 2, fixing pin 3, insert plate assembly 4, bolt assembly 5, upper wing plate 11 of the skylight slot body, upper wing plate 41 of the insert plate assembly, middle insert plate 42, large vertical plate 43, side plate 12, upper connecting plate 21, small vertical plate 22, and lower connecting plate 23. When it is necessary to remove the insert plate assembly 4 to observe, clean, and maintain the scraper chain, first remove the bolt assembly 5 connecting the baffle assembly 2 and the skylight slot body 1; then remove the fixing pin 3 that fixes the baffle assembly 2 to the insert plate assembly 4 and the skylight slot body 1, and remove the baffle assembly 2 with the handle; finally, as shown in the figure... Figure 2The insert plate assembly can be pulled out horizontally or diagonally upwards through the large notch in the side plate to achieve the above function. When reinstallation is required, the operation is reversed.
