Description

Technical Field

[0001] The invention belongs to the technical field of chain detection, in particular to a detection device for chain strength. Background Art

[0002] A chain is a flexible part connected by multiple metal links or rings of other materials. It is usually used to transmit mechanical power or to drag objects. After the chain is produced, the strength of the chain needs to be tested to determine whether the chain quality meets the requirements.

[0003] The patent with announcement number CN220473188U discloses a chain processing strength testing device, which solves the problem that in the process of strength testing the chain, it is not convenient to operate better, the efficiency of testing is reduced, and thus it is not convenient to achieve better practicality. It includes a testing table, and positioning studs are symmetrically installed on the top of the testing table. Positioning nuts are installed on the outer threads of the positioning studs. A testing mechanism is fixedly installed on the bottom of the testing table, and two positioning studs are connected to the testing mechanism. The testing mechanism includes a bar-shaped shell, and the bar-shaped shell is fixedly installed on the bottom of the testing table. A motor is fixedly installed in the middle of the bottom end of the bar-shaped shell, and a threaded rod is rotatably installed inside the bar-shaped shell. This patent can facilitate better operation and improve the efficiency of testing during the strength testing of the chain, so as to achieve better practicality.

[0004] However, the above technical solution still has the following deficiencies in practical application: The chain is pulled and the tension on the chain is displayed using a pressure gauge until the chain is broken, thereby completing the chain strength test. However, when the chain breaks, the fragments generated by the chain break will splash around, which may not only easily injure staff members, but may also damage surrounding equipment. In addition, usually, in order to ensure the accuracy of the test results, multiple identical chains are tested in turn, and after the test, the break position and degree of each chain are observed. By comparing multiple broken chains, it is easier to obtain the chain strength information. After the broken chain splashes around, it is necessary to manually collect and organize the chain fragments, which is not conducive to the subsequent chain comparison work.

[0005] To this end, the present invention provides a device for detecting chain strength. Summary of the invention

[0017] The beneficial effects of the present invention are as follows: 1.

[0018] 2. The chain strength detection device described in the present invention utilizes a flip-over material collection type covering mechanism and a rotating material receiving mechanism. When both ends of the chain are fixed, the lower shell is driven to fit with the upper shell, and the chain is in the closed space formed by the upper shell and the lower shell. When the chain breaks, since the chain is in the closed space formed by the upper shell and the lower shell, the broken fragments will only be concentrated in the inner cavity of the upper shell and the lower shell, thereby avoiding the chain fragments from splashing to the surroundings, thereby accidentally injuring the staff and damaging the surrounding equipment. In addition, when the chain is After the chain breaks, the positioning block is driven away from the chain, and the chain sleeved on the positioning column will fall into the lower shell, and then the scraper ring is driven to move from left to right, so that the chain fragments in the lower shell are concentrated on the right side of the lower shell, and then the lower shell is driven to rotate 180 degrees, so that the chain fragments in the lower shell fall to the right side of the upper end surface of the turntable. At this time, the chain fragments in the lower shell are cleared, and whenever there are chain fragments falling from the lower shell, the turntable rotates to remove the chain under the end of the lower shell, providing space for the subsequent chain. When a certain amount of chain is placed on the turntable After the chain is broken, the staff only needs to stand on one side of the workbench and observe the break position and degree of each chain in turn by driving the turntable to rotate. Each group of chain fragments is placed independently, which is easy to compare and not easy to confuse, so it is easier to obtain the strength information of the chain, eliminating the process of manually sorting the chain fragments. Moreover, after the staff observes and compares the chain fragments on the turntable, they drive multiple push plates to move radially at the same time and approach the axis of the discharge pipe, so that the chain fragments on the upper surface of the turntable can be pushed into the arc groove. When the chain fragments are pushed into the arc groove, they will fall out of the discharge pipe. The staff can use the collection container to collect the chain fragments that fall out of the discharge pipe, thereby ensuring that the turntable can continue to be used. At the same time, it is also convenient for the subsequent processing of the chain fragments. Moreover, compared with the method of driving the turntable to tilt to pour the chain fragments into the collection container, this method can make multiple groups of chain fragments more concentrated, avoiding the situation that the chain fragments cannot fall into the collection container accurately due to the small opening of the collection container, affecting the normal collection work.

[0033] A tension display screen 38 is provided on one side of the workbench 1 , and the tension display screen 38 is electrically connected to the tension sensor 33 .

[0034] Specifically, the existing chain processing strength testing equipment, when in use, pulls the chain and uses a pressure gauge to display the tension on the chain until the chain is broken, completing the chain strength testing operation. However, when the chain breaks, the fragments generated after the chain breaks will splash around, which is not only easy to accidentally injure workers, but also may damage surrounding equipment. In addition, usually, in order to ensure the accuracy of the test results, multiple identical chains will be tested in turn, and after the test work is completed, the break position and degree of each chain will be observed. By comparing multiple broken chains, it is easier to obtain the chain strength information. After the broken chain splashes around, it is necessary to manually collect and organize the chain fragments, which is not conducive to the subsequent chain comparison work. Therefore, in order to avoid the above problems, when the present embodiment is in use, after both ends of the chain are fixed, the motor 1 6 is used to drive the threaded rod 3 37 to rotate, so that the threaded block 8 moves upward until the lower shell 4 is fitted with the upper shell 3, and a through hole is provided on the right side of the lower shell 4, which can be fitted with the slide bar 2 15. At this time, the chain is in the closed space formed by the upper shell 3 and the lower shell 4, and then the motor 3 12 is used to drive the threaded rod 2 13 to rotate, so that the connecting block 35 can slide on the slide bar 1 14 and the threaded rod 2 13, and the slide bar 2 15 drives the tension sensor 33 to move away from the mounting block 2 36, so that the chain can be pulled, and the tension applied to the chain can be observed through the tension display screen 38; when the chain breaks, since the chain is in the closed space formed by the upper shell 3 and the lower shell 4, the broken fragments will only be concentrated in the inner cavity of the upper shell 3 and the lower shell 4, thereby avoiding the chain fragments from splashing to the surrounding area, thereby accidentally injuring the staff and damaging the surrounding equipment; When the chain breaks, the motor 7 30 is used again to drive the positioning blocks 31 on both sides to rotate so that the positioning blocks 31 are away from the chain. At this time, the chain sleeved on the positioning posts 32 will fall into the lower shell 4, and the remaining chain fragments will also fall into the inner cavity of the lower shell 4 under the action of gravity. Then, the motor 4 16 is used to drive the threaded rod 11 to rotate, so that the scraper ring 10 moves from left to right, so that the chain fragments in the lower shell 4 are concentrated on the right side of the lower shell 4, and then the motor 2 7 is used to drive the lower shell 4 to rotate 180 degrees, so that the chain fragments in the lower shell 4 fall to the right side of the upper end surface of the turntable 17. At this time, the chain fragments in the lower shell 4 are cleared, and then the staff can install the chain to be tested at the positioning posts 32, and then re- Repeating the above operation can realize the strength detection of multiple chains, and whenever there are chain fragments falling from the lower shell 4, the motor 5 27 drives the worm 28 to rotate, and the worm wheel 26, the discharge pipe 25, and the turntable 17 rotate, so that the chain below the end of the lower shell 4 can be moved away to provide a placement space for the subsequent chain. After a certain amount of chain fragments are placed on the turntable 17, the staff only needs to stand on one side of the workbench 1 and observe the break position and break degree of each chain in turn by driving the turntable 17 to rotate. Each group of chain fragments is placed independently, which is easy to compare and not easy to confuse, so it is easier to obtain the strength information of the chain, eliminating the process of manually sorting the chain fragments. After the staff observes and compares the chain fragments on the turntable, it is necessary to remove the chain fragments on the turntable so that the turntable 17 can continue to be used. At the same time, these chain fragments also need to be processed later. Since the chain fragments are distributed at various positions on the turntable 17, it is difficult to remove them manually, which increases the labor intensity of the workers. Therefore, in order to solve this problem, after the staff observes and compares the chain fragments on the turntable 17, the motor 6 29 is used to drive the connecting rod 1 22 on one side to rotate, so that the gear 21 on one side can be rotated, and through the rotation of the ring gear 5, multiple groups of connecting rods 1 22 and connecting rods 2 23 are rotated at the same time, and multiple push plates 18 move radially at the same time and approach the axis of the discharge pipe 25, so that the chain fragments on the upper surface of the turntable 17 can be pushed into the arc groove 24. , and during the movement of the push plate 18, the insert plate 19 also slides relative to the adjacent push plate 18, so that the multiple push plates 18 and the insert plates 19 form an encirclement without dead angles to ensure that all chain fragments can be pushed. When the chain fragments are pushed down to the arc groove 24, they will fall out of the discharge pipe 25. The personnel can use the collection container to collect the chain fragments that fall out of the discharge pipe 25, thereby ensuring that the turntable 17 can continue to be used. At the same time, it is also convenient for subsequent processing of the chain fragments. Moreover, compared with the method of driving the turntable 17 to tilt to pour the chain fragments into the collection container, this method can make multiple groups of chain fragments more concentrated, avoiding the situation that the chain fragments cannot fall into the collection container accurately due to the small opening of the collection container, affecting the normal collection work.

[0035] Working principle: The two ends of the chain are respectively mounted on the positioning columns 32 on both sides, and then the positioning block 31 is driven to rotate by the motor 7 30, and the two ends of the chain are pressed against the mounting block 1 34 and the mounting block 2 36 on both sides by the positioning block 31, thereby realizing the positioning of the two ends of the chain, and then ensuring the stability of the chain during the strength detection process. When both ends of the chain are fixed, the motor 1 6 is used to drive the threaded rod 3 37 to rotate, so that the threaded block 8 moves upward until the lower shell 4 is fitted with the upper shell 3, and a through hole is provided on the right side of the lower shell 4, which can be fitted with the slide rod 2 15. At this time, the chain is in the position formed by the upper shell 3 and the lower shell 4. In the enclosed space, the motor 3 12 is then used to drive the threaded rod 2 13 to rotate, so that the connecting block 35 can slide on the slide bar 14 and the threaded rod 2 13, and the slide bar 2 15 drives the tension sensor 33 to move away from the mounting block 2 36, so that the chain can be pulled, and the tension on the chain can be observed through the tension display screen 38; when the chain breaks, since the chain is in the enclosed space formed by the upper shell 3 and the lower shell 4, the broken fragments will only be concentrated in the inner cavity of the upper shell 3 and the lower shell 4, thereby avoiding the chain fragments from splashing to the surroundings, thereby accidentally injuring the staff and damaging the surrounding equipment; When the chain breaks, the motor 7 30 is used again to drive the positioning blocks 31 on both sides to rotate so that the positioning blocks 31 are away from the chain. At this time, the chain sleeved on the positioning posts 32 will fall into the lower shell 4, and the remaining chain fragments will also fall into the inner cavity of the lower shell 4 under the action of gravity. Then, the motor 4 16 is used to drive the threaded rod 11 to rotate, so that the scraper ring 10 moves from left to right, so that the chain fragments in the lower shell 4 are concentrated on the right side of the lower shell 4, and then the motor 2 7 is used to drive the lower shell 4 to rotate 180 degrees, so that the chain fragments in the lower shell 4 fall to the right side of the upper end surface of the turntable 17. At this time, the chain fragments in the lower shell 4 are cleared, and then the staff can install the chain to be tested at the positioning posts 32, and repeat the above operation to achieve multiple chain scraping. The strength detection work of the chain is carried out, and whenever chain fragments fall from the lower shell 4, the motor 5 27 drives the worm 28 to rotate, and the worm wheel 26, the discharge pipe 25, and the turntable 17 rotate, so that the chain below the end of the lower shell 4 can be moved away to provide a placement space for the subsequent chain. After a certain amount of chain fragments are placed on the turntable 17, the staff only needs to stand on one side of the workbench 1 and observe the breakage position and degree of each chain in turn by driving the turntable 17 to rotate. Each group of chain fragments is placed independently, which is easy to compare and not easy to confuse, so that it is easier to obtain the strength information of the chain, eliminating the process of manually sorting the chain fragments; after the staff observes and compares the chain fragments on the turntable, they need to clear the turntable. The chain fragments are removed so that the turntable 17 can continue to be used. At the same time, these chain fragments also need to be processed later. Since the chain fragments are distributed at various positions on the turntable 17, it is difficult to remove them manually, which increases the labor intensity of the workers. Therefore, in order to solve this problem, after the staff observes and compares the chain fragments on the turntable 17, the motor 6 29 is used to drive the connecting rod 1 22 on one side to rotate, so that the gear 21 on one side can be rotated, and through the rotation of the gear ring 5, multiple groups of connecting rods 1 22 and connecting rods 23 are rotated at the same time, and multiple push plates 18 move radially at the same time and approach the axis of the discharge pipe 25, so that the chain fragments on the upper surface of the turntable 17 can be pushed into the arc groove 24, and during the movement of the push plate 18, the insert The plate 19 also slides relative to the adjacent push plate 18, so that the multiple push plates 18 and the plug plates 19 form an encirclement without dead angles to ensure that all chain fragments can be pushed. When the chain fragments are pushed to the arc groove 24, they will fall out of the discharge pipe 25. The personnel can use the collection container to collect the chain fragments that fall out of the discharge pipe 25, thereby ensuring that the turntable 17 can continue to be used. At the same time, it is also convenient for subsequent processing of the chain fragments. Moreover, compared with the method of driving the turntable 17 to tilt to pour the chain fragments into the collection container, this method can make multiple groups of chain fragments more concentrated, avoiding the situation where the chain fragments cannot fall into the collection container accurately due to the small opening of the collection container, affecting the normal collection work.
