Description

Technical Field

[0001] The utility model relates to the technical field of transfer machines, and more specifically, to a transfer machine trough box capable of replacing a scraper without loosening a chain. Background Art

[0002] The scraper conveyor for the chute is a bridge-type scraper conveyor installed in the section transport tunnel below the working face of a mine. During operation, the chain is always tensioned, driven by the head sprocket, and the entire chain rotates in a circular motion. Scrapers and E-bolts are installed on the chain, which can transport materials such as coal.

[0003] During operation, scraper chains push coal and gangue, often damaging the scrapers and E-bolts. When a scraper is damaged, miners must operate the machine head telescopic mechanism to loosen the entire chain and remove the connecting link before replacing the scraper and E-bolts. After replacement, they must install a chain stopper, connect the link, and tighten the chain using the machine head telescopic mechanism. This cumbersome process, requiring numerous preparation steps, significantly impacts production efficiency. In practice, miners also remove the connecting link directly by using a single scraper. This poses a significant safety hazard.

[0004] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0005] In order to overcome the deficiencies in the prior art, a transfer machine trough box is provided for replacing scrapers without loosening the chain, thereby solving the efficiency and safety problems of replacing scrapers and E-type bolts.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A trough box for a transfer machine for replacing scrapers without loosening the chain, comprising a trough body, a middle plate, straight wing plates and curved wing plates, wherein the middle plate is horizontally arranged in the trough body, the straight wing plates and the curved wing plates are located at the upper end of the middle plate and are arranged in sequence along the running direction of the upper chain scraper chain, and a channel for the scraper to pass through is provided between the straight wing plates, the curved wing plates and the middle plate;

[0008] The side of the bent wing plate close to the straight wing plate is provided with an upward bend, and an oblique channel for the scraper to pass through is provided between the lower side of the bend and the upper end surface of the straight wing plate, and the outlet direction of the oblique channel is opposite to the running direction of the upper chain scraper chain.

[0009] Preferably, the middle plate includes a front middle plate, a rear middle plate and an insert plate, the front middle plate and the rear middle plate are fixedly arranged on the side plates of the trough body, and a reserved opening is provided between the front middle plate and the rear middle plate;

[0010] A connecting plate is fixedly provided on the outer side of the side plate, and a rectangular hole for inserting a plug-in plate is provided on the side plate at the upper end of the connecting plate, and the plug-in plate matches the size of the reserved opening.

[0011] Preferably, the connecting plate is provided with a through hole, the end of the inserting plate is provided with a U-shaped hole, and the inserting plate and the connecting plate are connected by inserting plate bolts passing through the U-shaped hole and the through hole.

[0012] Preferably, the curved wing plate is Z-shaped.

[0013] Preferably, a reinforcing rib plate is provided between the connecting plate and the side plate.

[0014] Preferably, the bent wing plate is formed by welding multiple wing plate sections.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This new system uses an upper channel for removing scrapers and a lower channel for removing E-bolts. Compared to conventional transfer machine troughs, which require loosening the chain before replacing the scrapers and E-bolts, this eliminates the labor waste and safety risks associated with loosening and tightening the chain. When the scraper chain is operating normally, the opening direction of the upper channel of the trough body is opposite to the direction of the scraper chain's operation, which has no effect on the normal operation of the scraper chain. The lower channel of the trough body is sealed with a plug plate, ensuring overall safety and reliability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figures 1 to 6 As shown, a transfer machine trough box for replacing scrapers without loosening the chain includes a trough body 1, a middle plate 2, straight wing plates 3 and bent wing plates 4. The middle plate 2 is horizontally arranged in the trough body 1, including a front middle plate 21, a rear middle plate 22 and an insert plate 23. Both sides of the front middle plate 21 and the rear middle plate 22 are fixedly arranged on the side plates 11 of the trough body 1. A reserved opening is provided between the front middle plate 21 and the rear middle plate 22, and the reserved opening is used to remove the E-type bolts.

[0027] A connecting plate 12 is fixedly mounted on the outside of the side panel 11. A rectangular hole is provided on the side panel 11 above the connecting plate 12, into which an insert plate 23 is inserted. The insert plate 23 matches the size of the reserved opening and, during normal operation, blocks the reserved opening. To secure the insert plate 23, a through-hole is provided on the connecting plate 12, and a U-shaped hole 24 is provided at the end of the insert plate 23. The insert plate 23 is connected to the connecting plate 12 via an insert plate bolt 13 that passes through the U-shaped hole 24 and the through-hole.

[0028] The straight wing plate 3 and the curved wing plate 4 are located at the upper end of the middle plate 2 and are arranged in sequence along the running direction of the upper chain scraper chain. A channel for the scraper 5 to pass through is provided between the straight wing plate 3, the curved wing plate 4 and the middle plate 2. During normal operation, the upper chain scraper chain passes through the channel.

[0029] The curved wing plate 4 has an upward bend 41 on one side near the straight wing plate 3. An oblique channel 42, through which the scraper can pass, is provided between the lower side of the bend 41 and the upper end surface of the straight wing plate 3. The exit direction of the oblique channel 42 is opposite to the direction of operation of the upper chain scraper chain. Therefore, the oblique channel 42 does not affect the normal operation of the scraper chain. When the scraper needs to be replaced, it can be removed through the oblique channel 42.

[0030] The above structure is applicable to a scraper chain assembled from scrapers 5, E-bolts 6, scraper nuts, and chain 7. The scrapers 5 and E-bolts 6 form a clamp to lock the chain 7. To disassemble the scraper 5, first remove the scraper nuts 6. Then, remove the scraper 5 from the oblique channel 42 above the chain and remove the E-bolts 6 from the bottom of the chain.

[0031] For other scraper chain structures, such as the structure of a combination of scrapers and beams, it is relatively simple and does not require the provision of reserved openings and plug-ins.

[0032] Preferably, the bent wing plate 4 is Z-shaped and is welded from multiple sections of wing plates.

[0033] A reinforcing rib 14 is provided between the connecting plate 12 and the side plate 11 to increase the rigidity of the connecting plate 12 .

[0034] The above only describes in detail the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention, and various changes should be included in the scope of protection of the present invention.
