Description

Technical Field

[0001] This invention relates to the field of scraper conveyor technology, specifically a scraper conveyor chain installation tool. Background Technology

[0002] The buried scraper conveyor mainly consists of a closed-section shell (trough), scraper chain, drive unit, tensioning device, and safety protection devices. The equipment has a simple structure, small size, good sealing performance, and is relatively convenient to install and maintain. It allows for multi-point feeding and multi-point unloading, and its process selection and layout are quite flexible. When conveying airborne, toxic, high-temperature, flammable, and explosive materials, it can improve working conditions and reduce environmental pollution.

[0003] The installation of the chain for a scraper conveyor is one of the important procedures in the installation of process equipment. Traditionally, the chain is connected by hammering the pins. However, hammering the pins to connect the chain can easily cause chain deformation, leading to chain derailment during later equipment operation. In addition, the scraper conveyor chain is relatively long, and it is cumbersome to lay it outside the machine and then place it inside the machine. This means that the scraper conveyor chain is usually assembled inside the machine, but the space inside the machine is relatively narrow, which makes the installation of the scraper conveyor chain even more difficult.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a scraper conveyor chain installation tool. Summary of the Invention

[0005] The purpose of this invention is to provide a scraper conveyor chain installation tool to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a scraper conveyor chain installation tool, comprising a mounting frame, a locking assembly, and an adjusting assembly. A first electric push rod is provided on the outer bottom of the mounting frame, and a housing is provided on the outer bottom of the first electric push rod. A displacement assembly is provided inside the housing. The displacement assembly includes a first motor, a bidirectional lead screw, a sliding seat, and a second electric push rod. The output end of the first motor is connected to the bidirectional lead screw, and the outer end of the bidirectional lead screw is provided with a sliding seat. The outer bottom of the sliding seat is connected to the second electric push rod. The locking assembly is located on the outer bottom of the second electric push rod. A displacement platform is located at the middle bottom of the housing, and a sliding groove is provided inside the displacement platform. The adjusting assembly is located inside the sliding groove.

[0007] Furthermore, the mounting frame is engaged with the scraper housing, and the mounting frame is perpendicular to the first electric push rod.

[0008] Furthermore, the engaging assembly includes a clamping seat, a second motor, a second lead screw, an adjusting groove, an engaging plate, and a bending sleeve. The second motor is mounted on the outer end of the clamping seat, and the output end of the second motor is connected to the second lead screw. An adjusting groove is provided on the inner side of the clamping seat. The engaging plate is connected to the outer end of the second lead screw, and a bending sleeve is provided on the outer end of the clamping seat.

[0009] Furthermore, the second motor drives the second lead screw to rotate, causing the locking plate to move inside the adjustment groove, and after the locking plate moves, the clamping seat engages with the scraper.

[0010] Furthermore, when the clamping seat moves down to the lowest point, the vertical center line of the bending sleeve coincides with the vertical center line of the rotating shaft, and the bending sleeve squeezes the pin when it is on the outer end of the rotating shaft.

[0011] Furthermore, the vertical center line of the mounting frame coincides with that of the scraper conveyor box, and the vertical center line of the mounting frame coincides with that of the box body.

[0012] Furthermore, the displacement stage and the housing are integrated, and the vertical center line of the housing coincides with the vertical center line of the displacement stage.

[0013] Furthermore, the adjustment assembly includes a third motor, a third lead screw, a sliding seat, a sliding block, a compression spring, a displacement plate, a compression seat, a pressure sensor, and an insertion rod. The output end of the third motor is connected to the third lead screw, and the outer end of the third lead screw is connected to the sliding seat. The outer end of the sliding seat is connected to the sliding block. Compression springs are provided on both sides inside the sliding block. The outer end of the compression springs is connected to the displacement plate. The outer right end of the displacement plate is connected to the compression seat. A pressure sensor is provided on the right side inside the sliding block. The outer bottom of the displacement plate is connected to the insertion rod.

[0014] Furthermore, the sliding block is elastically connected to the displacement plate via a compression spring, and the compression seat and the pressure sensor are located at the same height.

[0015] Furthermore, the width of the insertion rod is the same as the width of the chain body, and the insertion rod and the displacement plate are integrated.

[0016] This invention provides a scraper conveyor chain installation tool, which has the following beneficial effects:

[0017] 1. This invention utilizes a second electric actuator to move the clamping seat downwards. After downward movement, the clamping seat's inner contour aligns with the scraper. Simultaneously, a second motor drives a second lead screw to rotate, causing a locking plate to slide within the adjustment groove. This sliding displacement of the locking plate engages and secures the scraper. Once the clamping seat has stably clamped the scraper, a first motor drives a bidirectional lead screw to rotate, causing a sliding seat to gradually move the clamping seat towards the center of the scraper housing. At this point, the clamping seat and scraper are in a clamping state. This allows the clamping seat to adjust the position of the scraper and connecting plate inside the scraper housing, thereby achieving the clamping operation between the chain and the connecting plate. Because the width of the insertion rod is consistent with the width of the chain and the insertion rod is located at the vertical center line of the scraper housing, the insertion rod can limit the displacement trajectory of the connecting plate to prevent the connecting plate from bending due to excessive pushing. In addition, thanks to the center point limitation of the insertion rod, the chain and the connecting plate can be located at the center point of the scraper housing after clamping, which greatly simplifies the subsequent chain layout process.

[0018] 2. The bidirectional screw rotation of this invention drives the clamping seat to continue moving towards the center line of the scraper conveyor box. Because the vertical center line of the bending sleeve coincides with the vertical center line of the rotating shaft when the clamping seat reaches its lowest point, the clamping seat can engage with the rotating shaft after further displacement. Since the chain and connecting plate are now positioned at the vertical center line of the scraper conveyor box, the synchronous displacement of the clamping seats at both ends can also adjust the rotating shaft to the vertical center line of the scraper conveyor box. Through these operations, the positional accuracy of each component of the chain can be effectively guaranteed, and the rotating shaft can be adjusted to the vertical center line of the scraper conveyor box. After the vertical center line of the box is positioned, the clamping seat continues to move, which can bend the pin inserted inside the shaft. By bending the pin, the shaft can be locked, ensuring that the shaft will not come out from the inside of the chain and connecting plate during subsequent use. This operation eliminates the need for traditional manual hammering to bend the pin. Furthermore, by using a sleeve bending deformation method, it can effectively avoid the chain derailment caused by manual hammering due to pin or shaft deformation during scraper machine operation, as well as the difficulty in bending the pin when operating manually in narrow spaces. This greatly improves the ease of use of the equipment.

[0019] 3. The displacement of the clamping plate in this invention causes the clamping seat to clamp the scraper again. At this time, the second electric push rod reciprocates at high speed, enabling the scraper to rise and fall synchronously to simulate the rotation of the chain during operation. If the pin is not bent at this time, it will fall off during the high-speed lifting process. After the second electric push rod completes its high-speed reciprocating lifting, the bidirectional screw rotates in the opposite direction, causing the clamping seat to pull the scraper outward. If the pin falls off at this time, the scraper, connecting plate, and rotating shaft will be disengaged. At this time, the third motor drives the third screw to rotate, which enables the sliding seat to move the insertion rod. If the scraper, connecting plate, and rotating shaft are disengaged at this time, the scraper and connecting plate will be disengaged. If the connecting plate and the shaft do not detach, the scraper is held in place by the clamping seat. The insertion rod cannot move the chain when it moves. At the same time, the displacement force will cause the displacement plate to squeeze the compression spring, which allows the compression seat to squeeze the pressure sensor. When the pressure sensor senses the pressure, the chain assembly is qualified. Conversely, if the scraper, connecting plate and shaft detach, the insertion rod will separate them when it moves. The pressure sensor will move and will not trigger the pressure sensor. This allows the equipment to quickly detect the chain assembly quality after assembly.

[0020] 4. After the test is completed, the clamping seat releases its grip on the scraper, and the second electric push rod resets, causing the clamping seat to separate from the scraper. By displacing the insertion rod, the entire chain can be moved within the scraper housing. This allows the installed chain section to move away from the bottom of the housing. After the insertion rod is displaced, the first electric push rod moves the housing upward, separating the insertion rod from the chain. The sliding seat then resets the insertion rod, allowing it to move to the top of the unassembled chain section for subsequent chain assembly. Through these operations, the equipment can install the chain in a linear process, greatly improving the ease of operation. This also allows the insertion rod to perform chain positioning and testing, as well as displacement of the installed chain position. Attached Figure Description

[0028] Please see Figures 1 to 6 The present invention provides a technical solution: a scraper conveyor chain installation tool, including a mounting frame 1, a locking assembly 5, and an adjusting assembly 8. A first electric push rod 2 is provided on the bottom outer side of the mounting frame 1, and a housing 3 is provided on the bottom outer side of the first electric push rod 2. A displacement assembly 4 is provided inside the housing 3. The displacement assembly 4 includes a first motor 401, a bidirectional lead screw 402, a sliding seat 403, and a second electric push rod 404. The output end of the first motor 401 is connected to the bidirectional lead screw 402. The outer end of the bidirectional lead screw 402 is provided with a sliding seat 403. The bottom outer side of the sliding seat 403 is connected to the second electric push rod 404. The locking assembly 5 is placed on the bottom outer side of the second electric push rod 404. A displacement platform 6 is placed at the bottom middle of the housing 3, and a sliding groove 7 is provided inside the displacement platform 6. The adjusting assembly 8 is placed inside the sliding groove 7.

[0029] Please see Figures 1 to 6The mounting frame 1 is engaged with the scraper conveyor housing, and the mounting frame 1 is perpendicular to the first electric push rod 2. The engaging assembly 5 includes a clamping seat 501, a second motor 502, a second lead screw 503, an adjustment groove 504, an engaging plate 505, and a bending sleeve 506. The second motor 502 is mounted on the outer end of the clamping seat 501, and the output end of the second motor 502 is connected to the second lead screw 503. An adjustment groove 504 is provided on the inner side of the clamping seat 501. The engaging plate 505 is connected to the outer end of the second lead screw 503. The outer end of the clamping seat 501 is provided with... The bending sleeve 506, driven by the second motor 502, rotates the second lead screw 503, causing the locking plate 505 to shift inside the adjusting groove 504. After the locking plate 505 shifts, the clamping seat 501 engages with the scraper. When the clamping seat 501 moves to its lowest point, the vertical center line of the bending sleeve 506 coincides with the vertical center line of the rotating shaft. When the bending sleeve 506 is fitted onto the outer end of the rotating shaft, it presses against the pin. The vertical center lines of the mounting frame 1 and the scraper housing coincide, as do the vertical center lines of the mounting frame 1 and the housing 3. The displacement table 6 and the housing 3 are integrated. The housing 3 is integrated, and the vertical center line of the housing 3 coincides with the vertical center line of the displacement stage 6. The adjustment assembly 8 includes a third motor 801, a third lead screw 802, a sliding seat 803, a sliding block 804, a compression spring 805, a displacement plate 806, a compression seat 807, a pressure sensor 808, and an insertion rod 809. The output end of the third motor 801 is connected to the third lead screw 802, and the outer end of the third lead screw 802 is connected to the sliding seat 803. The outer end of the sliding seat 803 is connected to the sliding block 804. The sliding block 804 has internal features on both sides. A compression spring 805 is provided, and a displacement plate 806 is connected to the outer end of the compression spring 805. A compression seat 807 is connected to the outer right end of the displacement plate 806. A pressure sensor 808 is provided on the inner right side of the sliding block 804. An insertion rod 809 is connected to the outer bottom of the displacement plate 806. The sliding block 804 is elastically connected to the displacement plate 806 through the compression spring 805. The compression seat 807 and the pressure sensor 808 are located at the same height. The width of the insertion rod 809 is the same as the width of the chain body, and the insertion rod 809 and the displacement plate 806 are integrated.

[0030] The specific operation is as follows: After placing the various components of the chain inside the scraper conveyor housing, the operator inserts the shaft into the groove where the chain body and the connecting plate overlap, thus connecting the chain body and the connecting plate. The operator then inserts pins into the grooves at both ends of the shaft, achieving pre-assembly of the chain within the scraper conveyor housing (see...). Figure 2After the chain is pre-assembled, the worker aligns the groove at the bottom of the mounting frame 1 with the sides of the scraper housing, allowing the housing 3 to be placed inside the scraper housing. At this time, the first electric push rod 2 operates, driving the housing 3 to move downwards. After the housing 3 moves downwards, the insertion rod 809 moves down into the gap between the chain and the connecting plate. After the insertion rod 809 descends to the bottom surface and is in contact with the bottom surface of the scraper housing, the second electric push rod 404 operates, driving the clamping seat 501 to move downwards. After the clamping seat 501 moves downwards, its inner contour is in contact with the scraper. At this time, the second motor 502 drives the second lead screw 503 to rotate, causing the locking plate 505 to slide inside the adjusting groove 504. Through the sliding displacement of the locking plate 505, the clamping seat 501 can lock the scraper. After the clamping seat 501 stabilizes the scraper, the first motor 401 drives the bidirectional lead screw 402 to rotate, which causes the sliding seat 403 to gradually move the clamping seat 501 towards the center of the scraper housing. At this time, the clamping seat 501 and the scraper are in a clamping state, allowing the clamping seat 501 to adjust the scraper and connecting plate inside the scraper housing to achieve the pressing operation between the chain and the connecting plate. Because the width of the insertion rod 809 is consistent with the width of the chain, and the insertion rod 809 is located at the vertical center line of the scraper housing, the insertion rod 809 can limit the displacement trajectory of the connecting plate to prevent it from bending due to excessive pushing. Furthermore, thanks to the center point limitation of the insertion rod 809, the chain and connecting plate are positioned within the scraper housing after pressing. At the midpoint, this greatly simplifies the subsequent chain layout process. After the chain body and connecting plate are clamped and stabilized, the second lead screw 503 drives the locking plate 505 to separate from the scraper, releasing the clamping seat 501 from the scraper. At this time, the bidirectional lead screw 402 continues to rotate, driving the clamping seat 501 to continue moving towards the center line of the scraper housing. Because the vertical center line of the bending sleeve 506 coincides with the vertical center line of the rotating shaft when the clamping seat 501 moves down to the lowest point, the clamping seat 501 can continue to move and engage with the rotating shaft. Since the chain body and connecting plate are now at the vertical center line of the scraper housing, the synchronous displacement of the clamping seats 501 at both ends can also adjust the rotating shaft to the vertical center line of the scraper housing. Through the above operations... This operation effectively ensures the positional accuracy of each component of the chain. After the rotating shaft is adjusted to the vertical center line of the scraper conveyor box, the clamping seat 501 continues to move, bending the pin inserted inside the rotating shaft. By bending the pin, the rotating shaft is locked in place, ensuring that it will not come out from the chain body or the inner side of the connecting plate during subsequent use. This operation eliminates the need for traditional manual hammering to bend the pin, and by using a sleeve bending deformation method, it effectively avoids the chain derailment caused by manual hammering leading to pin or rotating shaft deformation during scraper conveyor box operation, as well as the difficulty in bending the pin during manual operation in narrow spaces. This greatly improves the ease of use of the equipment. After this section of the chain is installed, the locking plate 505 moves, causing the clamping seat 501 to clamp the scraper again.At this time, the second electric actuator 404 reciprocates at high speed, enabling the scraper to rise and fall synchronously, thus simulating the rotation of the chain during operation. If the pin is not bent at this time, it will fall off during the high-speed lifting process. After the second electric actuator 404 completes its high-speed reciprocating lifting, the bidirectional lead screw 402 rotates in the reverse direction, causing the clamping seat 501 to pull the scraper outward. If the pin falls off at this time, the scraper, connecting plate, and rotating shaft will disengage. At this time, the third motor 801 drives the third lead screw 802 to rotate, which in turn drives the sliding seat 803. When the insertion rod 809 moves, if the scraper, connecting plate, and rotating shaft have not dislodged, the scraper is held by the clamping seat 501, and the displacement of the insertion rod 809 cannot move the chain. Simultaneously, the displacement force will cause the displacement plate 806 to compress the compression spring 805, which allows the compression seat 807 to compress the pressure sensor 808. When the pressure sensor 808 senses the pressure, the chain assembly is considered successful. Conversely, if the scraper, connecting plate, and rotating shaft dislodge, the displacement of the insertion rod 809 will not cause the chain to move. This will cause it to separate, and the pressure sensor 808 will move it, but it will not trigger the pressure sensor 808. This allows the equipment to quickly detect the quality of the chain assembly after assembly. After the detection is completed, the clamping seat 501 releases its grip on the scraper, and at the same time, the second electric push rod 404 resets, causing the clamping seat 501 to separate from the scraper. By moving the insertion rod 809, the entire chain can be moved within the scraper housing. This allows the part of the chain that has been installed to move away from the bottom of the housing 3, while the insertion rod 809... After displacement 9 is completed, the first electric actuator 2 moves the housing 3 upward, separating the insertion rod 809 from the chain. The sliding seat 803 then moves the insertion rod 809 back to its original position, allowing it to move to the top of the unassembled part of the chain for subsequent chain assembly. Through these operations, the equipment can install the chain in a linear process, greatly improving operational convenience. Simultaneously, this allows the insertion rod 809 to both position and detect the chain, and also to move to the completed chain installation position.

[0031] In summary, when using this scraper conveyor chain installation tool, the operator first places the various components of the chain inside the scraper conveyor housing, then inserts the shaft into the groove where the chain body and the connecting plate overlap, enabling the chain body and the connecting plate to be connected. The operator then inserts the pins into the grooves at both ends of the shaft, thus achieving the pre-assembly of the chain inside the scraper conveyor housing.

[0032] After the chain is pre-assembled, the worker aligns the groove at the bottom of the mounting frame 1 with the sides of the scraper housing, allowing the housing 3 to be placed inside the scraper housing. At this time, the first electric push rod 2 operates, causing the housing 3 to move downwards. After the housing 3 moves downwards, the insertion rod 809 moves down into the gap between the chain and the connecting plate. After the insertion rod 809 descends to the bottom surface and is in contact with the bottom surface of the scraper housing, the second electric push rod 404 operates, causing the clamping seat 501 to move downwards. After the clamping seat 501 moves downwards, its inner contour is in contact with the scraper. At this time, the second motor 502 drives the second lead screw 503 to rotate, causing the locking plate 505 to slide inside the adjusting groove 504. Through the sliding displacement of the locking plate 505, the clamping seat 501 can lock and fix the scraper. After the scraper is clamped and stabilized, the first motor 401 drives the bidirectional lead screw 402 to rotate, which enables the sliding seat 403 to drive the clamping seat 501 to gradually move towards the center position of the scraper box. At this time, the clamping seat 501 and the scraper are in a clamping state, which allows the clamping seat 501 to drive the scraper and the connecting plate to adjust their positions inside the scraper box, so as to realize the pressing operation of the chain and the connecting plate. Since the width of the insertion rod 809 is consistent with the width of the chain, and the insertion rod 809 is located at the vertical center line of the scraper box, the insertion rod 809 can limit the displacement trajectory of the connecting plate to prevent the connecting plate from bending due to excessive pushing. In addition, thanks to the center point limit of the insertion rod 809, the chain and the connecting plate can be located at the center point of the scraper box after pressing, which can greatly simplify the subsequent chain layout process.

[0033] After the chain body and connecting plate are clamped and stabilized, the second lead screw 503 drives the locking plate 505 to separate from the scraper, releasing the clamping seat 501 from the scraper. At this time, the bidirectional lead screw 402 continues to rotate, driving the clamping seat 501 to continue moving towards the center line of the scraper housing. Because the vertical center line of the bending sleeve 506 coincides with the vertical center line of the rotating shaft when the clamping seat 501 moves to the lowest point, the clamping seat 501 can continue to move and engage with the rotating shaft. Therefore, at this time, the chain body and connecting plate have already... Positioned at the vertical center line of the scraper conveyor box, this allows the rotating shaft to be adjusted to the vertical center line of the scraper conveyor box when the clamping seats 501 at both ends move synchronously to push the rotating shaft. Through the above operations, the positional accuracy of each component of the chain can be effectively guaranteed. After the rotating shaft is adjusted to the vertical center line of the scraper conveyor box, the clamping seat 501 continues to move, which can bend the pin inserted inside the rotating shaft. By bending the pin, the rotating shaft can be locked, ensuring that the rotating shaft will not come out from the inside of the chain body and connecting plate during subsequent use.

[0034] After the chain segment is installed, the locking plate 505 shifts, causing the clamping seat 501 to clamp the scraper again. At this time, the second electric push rod 404 reciprocates at high speed, enabling the scraper to rise and fall synchronously to simulate the rotation of the chain during operation. If the pin is not bent at this time, it will fall off during the high-speed lifting process. After the second electric push rod 404 completes its high-speed reciprocating motion, the bidirectional screw 402 rotates in the opposite direction, causing the clamping seat 501 to pull the scraper outward. If the pin falls off at this time, the scraper, connecting plate, and rotating shaft will disengage. At this time, the third motor 801 drives the third screw 802 to rotate, causing the sliding seat 803 to move the insertion rod 809. If at this time... If the scraper, connecting plate, and rotating shaft do not detach, the scraper is held by the clamping seat 501. The insertion rod 809 cannot move the chain when it moves. At the same time, the displacement force will cause the displacement plate 806 to squeeze the compression spring 805. This allows the compression seat 807 to squeeze the pressure sensor 808. When the pressure sensor 808 senses the pressure, the chain assembly is qualified. Conversely, if the scraper, connecting plate, and rotating shaft detach, the insertion rod 809 will separate them when it moves. The pressure sensor 808 will move and will not trigger the pressure sensor 808. This allows the equipment to quickly detect the chain assembly quality after assembly.

[0035] Finally, after the inspection is completed, the clamping seat 501 releases its grip on the scraper, and at the same time, the second electric push rod 404 resets, causing the clamping seat 501 to separate from the scraper. By displacing the insertion rod 809, the entire chain can be moved within the scraper housing. This allows the installed chain section to move away from the bottom of the housing 3. After the insertion rod 809 has moved, the first electric push rod 2 moves the housing 3 upward, separating the insertion rod 809 from the chain. After the sliding seat 803 resets the insertion rod 809, it can be moved to the top of the unassembled part of the chain for subsequent chain assembly. Through the above operations, the equipment can install the chain in a linear process, which greatly improves the ease of operation. At the same time, this allows the insertion rod 809 to achieve chain positioning and inspection, as well as displacement of the chain installation position.
