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 component made up of multiple metal links or rings made 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 chain strength testing, it is inconvenient to perform better operation, reduces the efficiency of testing, and thus is not convenient to achieve better practicality. It includes a testing platform, and positioning studs are symmetrically installed on the top of the testing platform. Positioning nuts are installed on the outer threads of the positioning studs. A testing mechanism is fixedly installed on the bottom of the testing platform, and both 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 platform. 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 chain strength testing, thereby facilitating better practicality.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] The chain strength test is completed by pulling the chain and using a pressure gauge to display the tension on the chain until the chain is broken. However, when the chain breaks, the fragments generated after the chain breaks will fly around, which is not only easy to injure workers, but also may damage surrounding equipment. Moreover, 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 flies around, it is necessary to manually collect and organize the chain fragments, which is not conducive to the subsequent chain comparison work.

[0006] To this end, the present invention provides a device for detecting chain strength. Summary of the Invention

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. The chain strength detection device described in the present invention respectively sets the two ends of the chain on the positioning columns on both sides, and then uses the motor seven to drive the positioning blocks to rotate, and uses the positioning blocks to press the two ends of the chain onto the mounting blocks 1 and 2 on both sides, thereby realizing the positioning of the two ends of the chain and ensuring the stability of the chain during the strength detection process.

[0023] 2. The chain strength detection device described in the present invention utilizes a flip-collecting 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 surrounding area, thereby accidentally injuring staff and damaging surrounding equipment. In addition, when the chain breaks, 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 face of the turntable. At this time, the chain fragments in the lower shell are cleared, and every time a chain fragment falls from the lower shell, the turntable rotates to remove the chain below 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 at the side of the workbench and observe the fracture location 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 be confused, making it easier to obtain chain strength information and eliminating the process of manually sorting chain fragments. Moreover, after observing and comparing the chain fragments on the turntable, the staff drives 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, thus ensuring the continued use of the turntable. At the same time, it also facilitates 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 where the collection container opening is too small, resulting in the chain fragments not falling accurately into the collection container, affecting the normal collection work.

A motor 6 29 is fixedly connected to one side of the lower end surface of the workbench 1, and the output end of the motor 6 29 is fixedly connected to one end of the connecting rod 1 22.

[0050] 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 .

[0051] Specifically, the existing chain processing strength testing equipment, when in use, pulls the chain and uses a pressure gauge to display the tension applied to the chain until the chain is broken, thereby completing the chain strength testing operation. However, when the chain breaks, the fragments generated by the chain breakage will fly around, which not only easily injures workers but also may damage surrounding equipment. Moreover, usually, in order to ensure the accuracy of the test results, multiple identical chains will be tested in sequence, and after the test work is completed, the breakage position and degree of each chain will be observed. By comparing multiple broken chains, it is easier to obtain chain strength information. However, after the broken chain flies around, it is necessary to manually collect and organize the chain fragments, which is not conducive to the subsequent chain comparison work.

[0052] When the chain is broken, the broken pieces will only be concentrated in the inner cavity of the upper shell 3 and the lower shell 3, thereby preventing the chain from flying out of the way and causing the chain to be damaged.

[0053] 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 post 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 post 32 and re- Repeating the above operation can realize the strength detection of multiple chains. Moreover, 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 to move the chain below the end of the lower shell 4 away, providing a placement space for subsequent chains. After a certain amount of chain fragments are placed on the turntable 17, the staff only needs to stand on the 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 be confused, thereby making it easier to obtain the strength information of the chain and eliminating the process of manually sorting the chain fragments.

[0054] 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, manual removal is more difficult, 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 inserting plate 19 also slides relative to the adjacent push plates 18, so that multiple push plates 18 and inserting 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. 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 accurately fall into the collection container due to the small opening of the collection container, affecting the normal collection work.

[0055] Working principle: The two ends of the chain are respectively placed 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 tightly 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 test 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 bar 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 in the direction away from the mounting block 2 36, so that the chain is pulled, and the tension on the chain can be observed through the tension display 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 preventing the chain fragments from splashing to the surrounding area, thereby accidentally injuring staff and damaging surrounding equipment;

[0056] 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 post 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 post 32, and repeat the above operation to achieve multiple chain The strength detection work of the chain, 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, thereby making it 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 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 are moved 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 multiple push plates 18 and insert plates 19 form an encirclement without dead angles to ensure that all chain fragments can be pushed. When the chain fragments are pushed into the arc groove 24, they will fall out of the discharge pipe 25. 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.
