Description

Technical Field

[0001] The present application relates to the field of scraper machines, and in particular to a fault detection device for scraper machines. Background Art

[0002] A scraper is a continuous conveying device that uses a moving scraper chain to transport bulk materials in a rectangular cross-section housing with an opening on the upper end. However, during the operation of the scraper, the impact of materials on the scraper, looseness of the chain tensioning device, defects in the chain or U-bolts, etc. can easily cause the scraper chain to break.

[0003] When the chain of the scraper is broken, if the chain is broken in the upper half of the chain, the chain is repaired through the upper end opening of the scraper in the related art. However, when the chain is broken in the lower half of the chain, the side plate and bottom plate of the scraper need to be disassembled to find the location of the chain break and then repair the chain.

[0004] However, when the chain breaks in the lower half circle, the entire side plate of the scraper needs to be disassembled to find the broken position of the chain, which is time-consuming and laborious, and the maintenance efficiency of the broken chain in the lower half circle is low. Summary of the invention

[0005] In order to improve the maintenance efficiency of broken chains in the lower half of the circle, the present application provides a scraper conveyor fault detection device.

[0006] The present application provides a scraper fault detection device that adopts the following technical solution:

[0007] A scraper fault detection device comprises a shell and a machine body installed inside the shell, the machine body comprises two chains and a plurality of scrapers fixed between the two chains, the shell comprises two side plates and a bottom plate fixed between the two side plates, a driving motor for driving the two chains to rotate simultaneously is installed on the shell, each of the side plates is provided with a plurality of inspection openings arranged along the length direction of the machine body, a plurality of weighing sensors arranged along the length direction of the machine body are installed on the bottom plate, the plurality of weighing sensors are electrically connected to the same central controller, the central controller is electrically connected to the driving motor, and a maintenance component for sealing the inspection opening is installed at each of the inspection openings.

[0008] By adopting the above technical solution, the drive motor is started, and the drive motor drives the two chains to rotate together. The rotation of the two chains drives multiple scrapers to move, which is convenient for conveying materials. When the upper half of the chain breaks, the worker can observe and control the drive motor to stop. Then the broken chain is inspected between the two side plates. When the lower half of the chain breaks, the broken part falls down and contacts one of the weighing sensors. At this time, the central controller receives the feedback signal of the weighing sensor, and the central controller controls the drive motor to stop. At this time, the inspection component can be adjusted to open the inspection port near the weighing sensor that sends the signal. Then the broken chain is inspected through the inspection port, which makes it easy to quickly determine the range of the broken chain in the lower half of the circle, open the corresponding inspection port to inspect the broken chain, and improve the inspection efficiency of the broken chain in the lower half of the circle.

[0009] Preferably, the inspection assembly includes a door panel hinged to the upper edge of the inspection port, the lower end of the door panel is slidably connected to a locking plate, and the lower end of the locking plate faces away from a side wall inside the shell and contacts a side wall of the side panel close to the inside of the shell.

[0010] By adopting the above technical solution, the locking plate is slid relative to the door panel toward the door panel, so that the locking plate gradually disengages from the contact side panel. At this time, the vertical section of the inspection assembly is smaller than the vertical section of the inspection port. Then the door panel and the locking plate are rotated away from the inside of the shell, and the inspection port is opened. The operation is simple and convenient. When the inspection assembly blocks the inspection port, the locking plate is placed inside the shell and contacts a side wall of the side panel close to the inside of the shell. At this time, the locking plate is not easy to be separated from the inspection port, and the locking between the blocking assembly and the side panel is completed. There is no need to add too many locking parts. The structure is simple and can achieve the desired effect.

[0011] Preferably, a sliding block is fixedly connected to a side wall of the door panel close to the interior of the shell, a side wall of the locking plate facing away from the interior of the shell is provided with a vertically arranged sliding groove, and the sliding block is slidably connected to the sliding groove.

[0012] By adopting the above technical solution, when the locking plate moves relative to the door panel, the sliding block slides in the sliding groove, and the sliding groove and the sliding block play a guiding role in the movement of the locking plate relative to the door panel.

[0013] Preferably, a locking spring is provided in the sliding groove, one end of the locking spring is fixedly connected to the lower side wall of the sliding groove, and the other end is fixedly connected to the sliding block, and the locking plate is pressed against the upper surface of the bottom plate by the force of the locking spring.

[0014] By adopting the above technical solution, the locking plate is pressed against the upper surface of the bottom plate by the elastic force of the locking spring, thereby reinforcing the state of the locking plate being located inside the shell and reinforcing the state of the maintenance component blocking the maintenance port.

[0015] Preferably, a side wall of the side panel facing away from the interior of the shell is fixedly connected to a plurality of chains, one end of each chain is fixedly connected to a hook, and a side wall of each door panel facing away from the interior of the shell is fixedly connected to a hanging ring, and the hanging ring is used to hang with the hook.

[0016] By adopting the above technical solution, when the inspection component is rotated until the inspection port is opened, the hanging ring is hooked by the hook, which limits the inspection component from rotating in the direction close to the inspection port to block the inspection port, so that the inspection port remains open.

[0017] Preferably, the bottom plate is provided with a plurality of auxiliary ports arranged along the length direction of the machine body, and each of the auxiliary ports is equipped with a sealing assembly for sealing the auxiliary port, and the sealing assembly includes a support plate hinged to an edge of the auxiliary port, and two sealing plates are slidably connected to the support plate in opposite directions, and when each sealing plate contacts the upper surface of the bottom plate, the width of the sealing assembly is greater than the width of the auxiliary port and the sealing assembly seals the auxiliary port.

[0018] By adopting the above technical solution, the setting of the auxiliary port further facilitates the inspection of the broken chain at the lower half of the chain. When the auxiliary port needs to be opened, the two blocking plates are moved toward each other, and each blocking plate slides relative to the support plate until the width of the blocking assembly is smaller than the width of the auxiliary port. Then, the blocking assembly is rotated in the direction away from the auxiliary port. At this time, the blocking assembly passes through the auxiliary port and detaches from the inside of the shell, making it easier to open the inspection port. And when the blocking assembly contacts the upper surface of the bottom plate and blocks the auxiliary port, the blocking assembly is located inside the shell, which reduces the occurrence of accidental falling of the blocking assembly and ensures a safe production environment.

[0019] Preferably, each of the sealing plates is provided with a connecting groove at one end close to the support plate, and the connecting groove is slidably plugged into the support plate. Both side walls of the support plate are provided with grooves, and each groove is provided with a spring, one end of the spring is fixedly connected to the bottom wall of the groove, and the other end is fixedly connected to the sealing plate.

[0020] By adopting the above technical solution, when the two sealing plates are moved toward or away from each other, the support plate slides relative to the connecting groove, and the setting of the spring facilitates the application of force to the two sealing plates, thereby reducing the possibility of the two sealing plates accidentally sliding toward each other until the cross-section of the sealing assembly is smaller than the auxiliary port, thereby causing the sealing assembly to rotate out of the auxiliary port.

[0021] Preferably, a side wall of the support plate away from the hinged end of the support plate is provided with a long groove, a screw rod is slidably connected in the long groove, a surface wall of the support plate is provided with a through opening, a gear is rotatably connected in the through opening, the screw rod passes through the gear and is threadedly connected to the gear, the bottom wall of each connecting groove is fixedly connected with a rack, and each rack is meshed with the gear; when the two sealing plates move away from each other, one end of the screw rod extends out of the long groove and contacts the upper surface of the bottom plate on the auxiliary port side.

[0022] By adopting the above technical solution, one end of the screw rod contacts the upper surface of the bottom plate on one side of the auxiliary port, further reducing the occurrence of the blocking component rotating and thus disengaging from the auxiliary port, thus stabilizing the state of the auxiliary port being blocked. When the two blocking plates move toward each other, the movement of the blocking plates drives the gears to rotate through each rack, and the rotation of the gears drives the screw rod to gradually disengage from the bottom plate and retract into the long groove. When the two blocking plates move to the point where the cross section of the blocking component is smaller than the cross section of the auxiliary port, the blocking component can be rotated to open the auxiliary port.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] It is convenient to quickly determine the range of the broken chain in the lower half circle, open the corresponding inspection port to inspect the broken chain, and improve the inspection efficiency of the broken chain in the lower half circle;

[0025] The setting of the auxiliary port further facilitates the inspection of the broken chain at the lower half of the chain;

[0026] The plugging component is located inside the shell and blocks the auxiliary port, reducing the occurrence of accidental falling of the plugging component and ensuring a safe production environment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-Figure 6 This application is described in further detail.

[0035] The present application embodiment discloses a scraper machine fault detection device. Figure 1 and Figure 2 The scraper fault detection device includes a machine body 1 and a shell 2. The machine body 1 is installed inside the shell 2 with a rectangular cross section. The shell 2 includes two side plates 21 and a bottom plate 22 fixed between the two side plates 21. The bottom plate 22 is located at the lower ends of the two side plates 21. The machine body 1 includes two chains 11 installed inside the shell 2. A plurality of scrapers 12 are fixedly connected between the two chains 11. A receiving plate 13 is fixedly connected between the two side plates 21. The receiving plate 13 is located at the inner circle of each chain 11. A driving motor 14 is installed on the shell 2 to drive the chain 11 to rotate and thus convey materials.

[0036] When the scraper conveys materials, the materials are placed on the receiving plate 13 from one end of the scraper, and then the two chains 11 rotate synchronously to drive multiple scrapers 12 to scrape the materials on the receiving plate 13, so that the materials are conveyed from one end of the scraper conveyor to the other end.

[0037] A plurality of weighing sensors are mounted on the upper surface of the bottom plate 22, and the plurality of weighing sensors are evenly distributed along the length direction of the bottom plate 22. Each weighing sensor is electrically connected to the same central controller, and the central controller is electrically connected to the drive motor 14.

[0038] A plurality of inspection openings 211 are provided on each side plate 21 . The plurality of inspection openings 211 are arranged along the length direction of the side plate 21 . An inspection component 3 for sealing the inspection opening 211 is installed at each inspection opening 211 .

[0039] When the upper half of the chain 11 breaks, the worker can shut down the drive motor 14 and stop the conveying of the scraper through observation. When the lower half of the chain 11 breaks, the broken part of the chain 11 falls down onto the bottom plate 22. At this time, the broken part of the chain contacts one of the weighing sensors on the bottom plate 22. The central controller receives the feedback signal of the corresponding weighing sensor and then controls the drive motor 14 to stop. The central controller then determines the weighing sensor that sends the signal, and then inspects the broken chain through the inspection port 211 corresponding to the weighing sensor that sends the signal.

[0040] Each inspection assembly 3 includes a door panel 31 hinged to the upper edge of the inspection opening 211, and a locking plate 32 is slidably connected to a side of the door panel 31 close to the inside of the housing 2, and the locking plate 32 is vertically slidably connected to the door panel 31. The width of the door panel 31 is equal to the width of the locking plate 32, and the width of the door panel 31 is equal to the width of the inspection opening 211. A handle 33 is fixedly connected to a side of the locking plate 32 facing away from the inside of the housing 2, and a side of the lower end of the locking plate 32 facing away from the inside of the housing 2 contacts a side of the side panel 21 close to the inside of the housing 2.

[0041] When the inspection opening 211 needs to be opened, the handle 33 is pulled toward the door panel 31, and the handle 33 drives the locking plate 32 to move upward until the lower end of the locking plate 32 is higher than the lower edge of the inspection opening 211. Then, the locking plate 32 and the door panel 31 are rotated away from the interior of the housing, so that the inspection opening 211 can be opened.

[0042] When the inspection port 211 needs to be closed, the locking plate 32 and the door plate 31 are rotated toward the interior of the housing 2, and the locking plate 32 is slid away from the door plate 31. When the locking plate 32 is rotated to the interior of the housing 2, the locking plate 32 is pulled so that a side wall of the locking plate 32 away from the interior of the housing 2 contacts a side wall of the side plate 21 close to the interior of the housing 2, and the lower end of the locking plate 32 contacts the upper surface of the bottom plate 22.

[0043] A sliding groove 321 is formed on a side wall of the locking plate 32 facing away from the inside of the housing 2, and a sliding block 311 is fixedly connected to a side wall of the door panel 31 close to the inside of the housing 2, and the sliding block 311 is slidably connected to the sliding groove 321. A locking spring 34 is provided in the sliding groove 321, and one end of the locking spring 34 is fixedly connected to a side wall of the sliding groove 321 away from the door panel 31, and the other end is fixedly connected to the sliding block 311.

[0044] When the locking plate 32 contacts the upper surface of the bottom plate 22, the locking spring 34 is in a compressed state, and the locking plate 32 is pressed against the upper surface of the bottom plate 22 by the elastic force of the locking spring 34. In this way, the state of the inspection assembly 3 blocking the inspection opening 211 is strengthened, and the occurrence of accidental rotation of the locking plate 32 and the door panel 31 at the inspection opening 211 is reduced.

[0045] A plurality of chains 35 are fixedly connected to a side wall of each side panel 21 away from the inside of the housing 2, one chain 35 corresponds to one inspection opening 211, and the chain 35 is located above the inspection opening 211. A hook 36 is fixedly connected to one end of the chain 35 away from the side wall, and a hanging ring 37 is fixedly connected to a side wall of each door panel 31 away from the inside of the housing 2.

[0046] When the door panel 31 is rotated until the inspection opening 211 is opened, the corresponding hook 36 is pulled to engage with the hanging ring 37 , so that the door panel 31 is in a state of being separated from the inspection opening 211 , and it is convenient to operate through the inspection opening 211 .

[0047] Reference Figure 1 and Figure 3 In order to facilitate the inspection and repair of the broken chain at the lower half of the chain 11 more smoothly, a plurality of auxiliary openings 221 are opened on the bottom plate 22, and a blocking component 4 for blocking the auxiliary opening 221 is installed at each auxiliary opening 221.

[0048] Reference Figure 3 and Figure 4 The blocking assembly 4 includes a support plate 41 and a blocking plate 42, one end of the support plate 41 is hinged to the auxiliary port 221. The blocking plate 42 includes two blocking plates 421, the support plate 41 is located between the two blocking plates 421, and each blocking plate 421 is slidably connected to the support plate 41. A weighing sensor is installed on the upper surface of each blocking plate 421.

[0049] The two blocking plates 421 are slid toward each other along the width direction of the support plate 41 until the width of the blocking component 4 is smaller than the width of the auxiliary port 221. Then, the blocking component 4 is rotated toward the auxiliary port 221 until the blocking component 4 passes through the auxiliary port 221 and enters the interior of the housing 2. The two blocking plates 421 are then moved away from each other until the width of the blocking component 4 is larger than the width of the auxiliary port 221. At this time, the blocking component 4 overlaps the upper surface of the bottom plate 22, and it is difficult for the blocking component 4 to rotate downward to disengage from the auxiliary port 221, and the blocking component 4 blocks the auxiliary port 221.

[0050] Reference Figure 4 , Figure 5 and Figure 6 Each blocking plate 421 has a connection groove 4211 at one end close to the support plate 41, and each connection groove 4211 is slidably plugged with the support plate 41. Grooves 411 are provided on both sides of the support plate 41, and a connection spring 43 is provided in each groove 411, and one end of each connection spring 43 is fixedly connected to the bottom wall of the groove 411, and the other end is fixedly connected to the blocking plate 421. The lower surfaces of the two blocking plates 421 are flush with each other, and the upper surfaces of the two blocking plates 421 are also flush with each other.

[0051] In order to improve the stability of the plugging assembly 4 in plugging the auxiliary port 221, a locking member 44 is installed on the support plate 41. A long groove 412 is provided on the side of the support plate 41 away from the hinged end of the support plate 41. The long groove 412 extends along the length direction of the support plate 41. The locking member 44 includes a screw rod 441 slidably connected to the long groove 412. A through hole 413 is provided on the upper surface of the support plate 41. The through hole 413 passes through the support plate 41 and is connected to the long groove 412. A gear 442 is rotatably connected inside the through hole 413.

[0052] Each connection groove 4211 has a mounting groove 4212 formed on its bottom wall, a rack 443 is fixedly connected in the mounting groove 4212, each rack 443 is meshed with a gear 442, a screw rod 441 passes through the middle of the gear 442 and is threadedly connected to the gear 442. Since the screw rod 441 passes through the middle of the gear 442, the gear 442 and the side wall of the through opening 413 can be rotatably connected in that an annular groove is formed on the side wall of the through opening 413, and mounting blocks are fixedly connected to both side walls of the gear 442, one mounting block corresponds to one annular groove, each mounting block is inserted into the corresponding annular groove and is rotatably connected to the annular groove, and the annular groove is concentrically arranged with the gear 442.

[0053] When the two blocking plates 421 move toward each other, each rack 443 drives the gear 442 to rotate, and the gear 442 rotates to drive the screw rod 441 to move toward the inside of the long groove 412. When the width of the blocking component 4 is smaller than the width of the auxiliary opening 221, the screw rod 441 is completely retracted into the long groove 412. At this time, it is convenient for the blocking component 4 to rotate and pass through the auxiliary opening 221.

[0054] When the two blocking plates 421 move away from each other, each rack 443 drives the gear 442 to rotate, and the gear 442 rotates to drive the screw rod 441 to move away from the inside of the long groove 412. When the cross section of the blocking component 4 is larger than the cross section of the auxiliary port 221, one end of the screw rod 441 extends out of the long groove 412 and contacts the upper surface of the bottom plate 22 on one side of the auxiliary port 221, thereby reinforcing the state in which the blocking component 4 blocks the auxiliary port 221.

[0055] The side wall of the long slot 412 is provided with a guide slot 414, which is arranged along the length direction of the long slot 412. The side wall of the screw rod 441 is fixedly connected with a guide block 444, which is slidably connected with the guide slot 414. The guide block 444 and the guide slot 414 provide a guide for the movement of the screw rod 441.

[0056] The implementation principle of a scraper fault detection device in an embodiment of the present application is: the material is conveyed by the scraper, and when the upper half of the chain 11 breaks, the worker observes and controls the drive motor 14 to shut down, and then the broken chain is inspected and repaired through the opening of the shell 2.

[0057] When the lower half of the chain 11 is broken, the chain 11 at the broken position contacts the upper surface of the bottom plate 22 downwards, and when the corresponding weighing sensor senses the broken chain, the central controller receives the signal from the corresponding weighing sensor and controls the drive motor 14 to stop. Then, the inspection port 211 and the auxiliary port 221 at the weighing sensor that issued the alarm are opened to inspect the broken chain.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
