Description

Technical Field

[0001] This utility model relates to the field of steel strand testing technology, specifically to a steel strand testing machine device. Background Technology

[0002] Steel strands have advantages such as good plasticity, no joints, easy use, and high strength. They are widely used in fixed structures such as bridges, high-rise buildings, and large factory buildings. The elongation of steel strands is one of the main mechanical properties of steel strands.

[0003] Utility model publication CN 205192851U discloses a strain testing device for a steel strand relaxation test machine: It includes a clamp, comprising an upper clamp and a lower clamp, each with a front clamp. Both the upper and lower clamps have semi-circular grooves. The front clamp has a semi-circular groove identical to the one on the upper and lower clamps. A knife edge, composed of two semi-circular arc plates, is installed within the circular groove formed by the upper and lower clamps. The front clamp is fixed to the upper and lower clamps by screws, with an elastic washer between the screws and the front clamp. The upper and lower clamps are mounted on guide rods, which are two in number and symmetrically distributed. A linear bearing is provided between the lower clamp and the guide rods. A grating ruler is located on the upper side of the guide rod above the upper clamp.

[0004] In the aforementioned application, the interaction between the clamp and the guide rod assembly makes it difficult to perform tensile strength testing on the steel strand when it is being tested in the clamp, resulting in the inability of staff to provide key indicators of the tensile strength of the steel strand. Therefore, we propose a steel strand testing machine device. Utility Model Content

[0005] This utility model proposes a steel strand testing machine device.

[0006] The technical solution of this utility model is as follows: A steel strand testing machine device includes a test bench, a support column fixedly connected to the bottom of the test bench, a control panel provided on the top of the test bench, and a tensile strength testing mechanism provided on the top of the test bench; the tensile strength testing mechanism includes a bidirectional motor, the top of the bidirectional motor fixedly connected to the inside of the test bench, a threaded rod fixedly connected to the output shaft of the bidirectional motor, a moving groove provided on the top of the test bench, the circumferential surface of the threaded rod penetrating the inside of the moving groove and rotatably connected to the inside of the moving groove, a moving block threadedly connected to the circumferential surface of the threaded rod, a connecting rod fixedly connected to the top of the moving block, a test plate fixedly connected to the top of the connecting rod, and a fixing hole provided on the side of the test plate.

[0007] The test plate has a locking groove inside, and a locking shaft passes through the side of the test plate and is rotatably connected to the circumferential surface of the locking shaft. A locking plate is threadedly connected to the circumferential surface of the locking shaft, and the side of the locking plate is slidably connected to the inside of the locking groove. This design allows the steel strand to be locked by the locking plate when the locking shaft rotates through the inside of the test plate.

[0008] A turning handle is fixedly connected to the circumference of the locking shaft, an anti-slip block is fixedly connected inside the locking plate, and a limit plate is fixedly passed through the circumference of the threaded rod. The function of the turning handle is to facilitate the operator to rotate the locking shaft, the function of the anti-slip block is to prevent the steel strand from slipping after locking, and the function of the limit plate is to limit the displacement distance of the moving block.

[0009] The number of threaded rods, test plates, and locking shafts is set to two, and they are symmetrical to each other along the vertical central axis of the test bench. This design is intended to stably lock both ends of the steel strand and prevent them from falling off during operation.

[0010] The test bench is equipped with a waste cleaning mechanism on its top. The waste cleaning mechanism includes a rotating shaft, one end of which is fixedly connected to the end of a threaded rod away from the output shaft of a bidirectional motor. A gear is fixedly threaded through the circumference of the rotating shaft. A sliding groove is provided inside the moving slot, and a sliding column is slidably connected inside the sliding groove. A rack is fixedly connected to the end of the sliding column away from the inside of the sliding groove. A moving rod is fixedly connected to the top of the rack, and a cleaning brush is fixedly connected to the end of the moving rod away from the top of the rack. A waste collection trough is provided on the top of the test bench. The function of the waste cleaning mechanism is to clean the broken steel wire rope after testing, ensuring the cleanliness of the top of the test bench.

[0011] The waste collection trough has an inclined groove inside, and the test bench has a cleaning trough on its side. The inclined groove is used to transport the cleaned waste, and the cleaning trough is used to place the collection box.

[0012] A collection box is slidably connected inside the cleaning tank, and a pull handle is fixedly connected to the side of the collection box. The function of the collection box is to collect the waste after cleaning, and the function of pulling the handle is to facilitate the staff to pull out the collection box after collection.

[0013] The circumferential surface of the gear meshes with the side surface of the rack, and the bottom of the cleaning brush contacts the top of the waste collection trough. The meshing of the circumferential surface of the gear with the side surface of the rack ensures that the rotation of the gear can drive the rack to move. The contact between the bottom of the cleaning brush and the top of the waste collection trough ensures that the movement of the cleaning brush can clean the waste inside the waste collection trough.

[0014] The working principle and beneficial effects of this utility model are as follows: 1. This utility model utilizes the interoperability of components such as a bidirectional motor, a test plate, and a locking plate in a tensile strength testing mechanism. When testing steel strands, the operator inserts both ends of the steel strand through fixing holes into the test plate. Then, the locking shaft ensures that the anti-slip block inside the locking plate is in close contact with the steel strand for locking. The operator then activates the bidirectional motor via the control panel, causing the moving block to move and, through the connecting rod, move the test plate, allowing the steel strand to break under tensile force. The test data is then displayed on the control panel. This design achieves the effect of testing the tensile strength of steel strands, ensuring the accuracy of the tested steel strand load-bearing capacity values.

[0015] 2. This utility model utilizes the interoperability of components such as gears, racks, and cleaning brushes in the waste cleaning mechanism. When the tensile strength testing mechanism is working, the threaded rod rotates counterclockwise, driving the rotating shaft to rotate counterclockwise. Through the meshing between the gears and racks, the cleaning brush moves to clean the waste inside the waste collection tank. The cleaned waste slides down the inclined groove into the collection box. This design achieves the effect of cleaning the top of the test bench, effectively preventing waste accumulation on the top of the test bench and ensuring cleanliness.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1 like Figures 1-5As shown, this embodiment proposes a steel strand testing machine device, including a test bench 1, a support column 2 fixedly connected to the bottom of the test bench 1, a control panel 3 set on the top of the test bench 1, and a tensile strength testing mechanism 4 set on the top of the test bench 1; the tensile strength testing mechanism 4 includes a bidirectional motor 41, the top of the bidirectional motor 41 fixedly connected to the inside of the test bench 1, a threaded rod 42 fixedly connected to the output shaft of the bidirectional motor 41, a moving groove 43 opened on the top of the test bench 1, the circumferential surface of the threaded rod 42 penetrating the inside of the moving groove 43 and rotatably connected to the inside of the moving groove 43, a moving block 44 threadedly connected to the circumferential surface of the threaded rod 42, a connecting rod 45 fixedly connected to the top of the moving block 44, a test plate 46 fixedly connected to the top of the connecting rod 45, a fixing hole 47 opened on the side of the test plate 46, a locking groove 48 opened inside the test plate 46, a locking shaft 49 penetrating the side of the test plate 46 and connected to the locking shaft 47. The circumferential surface of the locking shaft 49 is rotated and connected to the locking plate 410. The side of the locking plate 410 is slidably connected to the inside of the locking groove 48. This design allows the steel strand to be locked by the locking plate 410 when the steel strand passes through the inside of the test plate 46 through the rotation of the locking shaft 49. The circumferential surface of the locking shaft 49 is fixedly connected to the turning handle 411. The inside of the locking plate 410 is fixedly connected to the anti-slip block 412. The circumferential surface of the threaded rod 42 is fixedly connected to the limit plate 413. The function of the turning handle 411 is to facilitate the operator to turn the locking shaft 49. The function of the anti-slip block 412 is to prevent the steel strand from slipping after locking. The function of the limit plate 413 is to limit the displacement distance of the moving block 44. The number of threaded rod 42, test plate 46 and locking shaft 49 is set to two, and they are symmetrical about each other along the vertical central axis of the test bench 1. This design is used to stably lock both ends of the steel strand and prevent it from falling off during operation.

[0022] In this embodiment, when the steel strand needs to be tested, the operator passes both ends of the steel strand through the fixing holes 47 into the test plate 46. Then, the operator rotates the handle 411, causing the locking plate 410 to move within the locking groove 48 via the locking shaft 49. This causes the anti-slip block 412 inside the locking plate 410 to make tight contact with the steel strand and lock it in place. Then, the operator starts the bidirectional motor 41 via the control panel 3. The output shaft of the bidirectional motor 41 rotates counterclockwise, causing the threaded rod 42 to rotate counterclockwise. The moving block 44, which is threaded to the circumferential surface of the threaded rod 42, moves outward within the moving groove 43. The movement of the moving block 44 drives the test plate 46 to move via the connecting rod 45, causing the steel strand to break under tensile force. At this time, the test data is displayed on the control panel 3.

[0023] Example 2 like Figures 1-5As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that the top of the test bench 1 is provided with a waste cleaning mechanism 5. The waste cleaning mechanism 5 includes a rotating shaft 51, one end of which is fixedly connected to the end of the threaded rod 42 away from the output shaft of the bidirectional motor 41. A gear 52 is fixedly passed through the circumferential surface of the rotating shaft 51. A sliding groove 53 is opened inside the moving groove 43. A sliding column 54 is slidably connected inside the sliding groove 53. A rack 55 is fixedly connected to the end of the sliding column 54 away from the inside of the sliding groove 53. A moving rod 56 is fixedly connected to the top of the rack 55. A cleaning brush 57 is fixedly connected to the end of the moving rod 56 away from the top of the rack 55. A waste collection groove 58 is opened on the top of the test bench 1. The function of the waste cleaning mechanism 5 is to clean the broken steel wire rope after the test, ensuring the cleanliness of the top of the test bench 1. An inclined groove 59 is opened inside the waste collection groove 58. The side of the test bench 1 The surface is provided with a cleaning trough 510, and the inclined trough 59 is used to transport the waste material after cleaning. The cleaning trough 510 is used to place the collection box 511. The collection box 511 is slidably connected inside the cleaning trough 510. A pull handle 512 is fixedly connected to the side of the collection box 511. The function of the collection box 511 is to collect the waste material after cleaning. The function of the pull handle 512 is to facilitate the staff to pull out the collection box 511 after collection. The circumferential surface of the gear 52 meshes with the side of the rack 55. The bottom of the cleaning brush 57 contacts the top of the waste material collection trough 58. The function of the circumferential surface of the gear 52 meshing with the side of the rack 55 is to ensure that the rotation of the gear 52 can drive the rack 55 to move. The function of the bottom of the cleaning brush 57 contacting the top of the waste material collection trough 58 is to ensure that the movement of the cleaning brush 57 can clean the waste material inside the waste material collection trough 58.

[0024] In this embodiment, when the tensile strength testing mechanism 4 is working, the waste generated by the steel strand falls into the waste collection tank 58 to prevent waste accumulation. Therefore, the threaded rod 42 rotates counterclockwise, which drives the rotating shaft 51 to rotate counterclockwise. The rotating shaft 51 rotates, which drives the gear 52 to rotate counterclockwise. Through the meshing between the gear 52 and the rack 55, the gear 52 rotates, which drives the rack 55 to move from right to left through the sliding column 54 in the sliding groove 53. The movement of the rack 55 from right to left drives the cleaning brush 57 to move from right to left through the moving rod 56. The cleaning brush 57 moves to clean the waste inside the waste collection tank 58. The cleaned waste slides down the inclined groove 59 into the collection box 511. Finally, the operator pulls the handle 512 to pull the collected collection box 511 out of the cleaning tank 510 and processes the waste inside the collection box 511.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
