Description

Technical Field

[0001] This application relates to the field of strand testing, and in particular to a testing tooling for strands used in photovoltaic panels. Background Art

[0002] A strand is a steel product composed of multiple steel wires twisted together. The surface of carbon steel can be coated with a galvanized layer, a zinc-aluminum alloy layer, an aluminum-clad layer, a copper-plated layer, epoxy resin, etc. according to needs. Strands are usually used for catenaries, guy wires, strengthening cores, etc.

[0003] In the related art, an operator applies a strand to a photovoltaic support and uses the strand to connect two adjacent photovoltaic panels. Before the operator uses the strand, it is necessary to conduct a reliability test on the strand. The operator passes the two ends of the strand through a concrete block respectively, and then uses an anchor to fix the two ends of the strand at the corresponding concrete block. The operator then uses a protector to fix the fixing bracket to the strand. After the fixing is completed, the output end of the jack on the fixing bracket contacts the strand. The operator controls the jack to apply pressure to the strand, and then determines the reliability of the strand by observing a wire-pulling displacement gauge. To observe the application of the strand to the photovoltaic panel, the operator connects the photovoltaic panel to a hoop, and at this time the hoop connects two adjacent photovoltaic panels.

[0004] In view of the above related art, the inventor found that during the process of simulating the working condition of the strand in rainy days, rainwater easily causes rust at the contact between the strand and the anchor and at the connection between the hoop and two adjacent photovoltaic panels, reducing the stability during the strand test, thereby causing deviation in the test value of the strand reliability, so improvement is needed. Summary of the Invention

[0005] In order to improve the accuracy of testing the reliability of strands, this application provides a testing tooling for strands used in photovoltaic panels.

[0006] A testing tooling for strands used in photovoltaic panels provided by this application adopts the following technical solution:

[0008] The stable component includes a first stable block and a second stable block. The first stable block abuts against the photovoltaic panel. A stable hole for the steel strand body to pass through is formed in the first stable block. A stable groove cooperating with the second stable block is formed in the first stable block.

A fixing member is provided on the first stable block, and the fixing member is used to mount the first stable block and the second stable block on the photovoltaic panel.

[0009] By adopting the above technical solution, when it is necessary to test the steel strand body, the operator fixes the two ends of the steel strand body on the test rack respectively, then connects the simulation component to the steel strand body, and then clamps the first stable block on the steel strand body so that the steel strand body abuts against the inner wall of the stable hole. The operator then inserts the second stable block into the stable groove along the axial direction of the steel strand, so that the steel strand body abuts tightly against the inner wall of the cooperating groove. The operator then places the photovoltaic panel on the first stable block, and the operator then uses the fixing member to fix the first stable block and the second stable block on the photovoltaic panel. At this time, the fixing member squeezes the second stable block, and the second stable block moves towards the steel strand body, so that the first stable block and the second stable block clamp the steel strand body, reducing the possibility of the steel strand body separating from the photovoltaic panel. At the same time, under the action of the protection component, it is not easy for external liquid to cause rust at the connection between the steel strand body and the test rack, improving the connection stability between the steel strand body and the test rack. The operator then uses the simulation component to simulate the working state of the steel strand body and the photovoltaic panel at the same time. The stable component and the protection component simultaneously provide support and protection for the steel strand body and the photovoltaic panel, thereby improving the test accuracy when the operator detects the reliability of the steel strand.

[0010] Preferably, a limiting block is provided on the second stable block, a limiting groove is formed in the inner wall of the stable groove, the limiting groove communicates with the stable hole, and the limiting block is arranged in the limiting groove.

[0011] By adopting the above technical solution, the limiting block is clamped with the limiting groove, improving the connection stability between the second stable block and the first stable block, so as to improve the limiting ability of the first stable block and the second stable block for the steel strand body. And under the action of the fixing member, the limiting block further abuts tightly against the inner wall of the limiting groove, thereby further improving the connection stability between the steel strand body and the photovoltaic panel and further improving the detection accuracy when the operator detects the reliability of the steel strand body.

[0012] Preferably, a plurality of reinforcing protrusions are provided on the inner wall of the cooperating groove and the inner wall of the stable hole, and each of the reinforcing protrusions abuts tightly against the steel strand body.

[0013] By adopting the above technical solution, each reinforcing protrusion increases the contact area between the first stabilizing block and the second stabilizing block and the steel strand body, further improving the connection stability between the first stabilizing block and the second stabilizing block and the steel strand body, so that the operator can more accurately detect the reliability of the steel strand body.

[0014] Preferably, an anti-friction layer is provided on the first stabilizing block, and the anti-friction layer abuts against the photovoltaic panel.

[0015] By adopting the above technical solution, the anti-friction layer increases the friction between the first stabilizing block and the photovoltaic panel, so that the first stabilizing block can stably provide support for the photovoltaic panel, and at the same time improves the connection stability between the first stabilizing block and the photovoltaic panel.

[0016] Preferably, the protection component includes a protective cover, the protective cover is connected to the test rack, a protective groove is opened on one side of the protective cover close to the test rack, the steel strand body is arranged in the protective groove, the steel strand body is connected to the test rack through a connecting component, a partition is arranged in the protective groove, the partition divides the protective groove into a protective space for protecting the steel strand body and the connecting component and a filling space for supporting the steel strand body, a protective medium is stored in the protective space, a filling medium is stored in the filling space, a through hole is opened on the partition, and one end of the steel strand body far away from the test rack extends into the filling space after passing through the through hole.

[0017] By adopting the above technical solution, the operator first uses the connecting component to connect the steel strand body to the test rack, and then fixes the protective cover to the test rack. At this time, the steel strand body and the connecting component are located in the protective space, and the steel strand body extends into the filling space. The protective medium in the protective space provides protection for the steel strand body and the connecting component, making it difficult for the connecting component to separate from the steel strand body. The filling medium in the filling space provides limit and support for the steel strand body, so as to facilitate the subsequent detection of the steel strand body. At the same time, the protective cover blocks the contact between the outside liquid and the steel strand body and the connecting component, reducing the possibility of rust at the contact part between the steel strand body and the connecting component, thereby improving the connection stability between the steel strand body and the test rack, so as to improve the accuracy of the operator when detecting the reliability of the steel strand body.

[0018] Preferably, a filling hole is opened on the protective cover, and the filling hole is communicated with the filling space.

[0019] By adopting the above technical solution, the filling hole facilitates the operator to fill the filling medium into the filling space, and at the same time facilitates the operator to supplement the filling medium through the filling hole, so as to improve the connection stability between the steel strand body and the test rack.

[0021] By adopting the above technical solution, when it is necessary to connect the steel strand body to the test stand, the operator passes the steel strand body through the first connecting hole, and then uses a front-loading jack to clamp the two opposite connecting clamping pieces into the first connecting hole, so that the steel strand body is clamped tightly against the inner wall of the second connecting hole. Then the operator abuts the connecting sleeve against the fixing component, thus completing the installation between the steel strand body and the test stand. At this time, under the action of the two connecting clamping pieces, a limit is provided for the steel strand body, improving the connection stability between the steel strand body and the fixing component, so that the operator can more accurately detect the reliability of the steel strand body subsequently.

[0022] Preferably, a corrugated spring is provided between the connecting sleeve and the fixing component.

[0023] By adopting the above technical solution, the corrugated spring provides support and limit for the connecting sleeve, making the connecting sleeve not easily separated from the connecting clamping piece, thereby improving the connection stability between the steel strand body and the test stand. At the same time, the corrugated spring reduces the possibility of wear between the connecting sleeve and the fixing component.

[0025] The adjustment component includes a plurality of adjustment columns, each adjustment column is arranged on the support seat, a plurality of adjustment holes are formed in the test stand, one adjustment column slides correspondingly in each adjustment hole, and each adjustment column is connected to the test stand through a nut.

[0026] By adopting the above technical solution, when it is necessary to connect the simulation component to the steel strand body, the operator first fixes the simulation part on the support base, and then the operator moves the support base. The support base drives each adjusting column to move. When the limiting component faces the steel strand body, the adjustment of the distance between the simulation part and the steel strand body is completed. After the adjustment is completed, the operator uses nuts to fix the positions of the support base and the adjusting column, and then uses the limiting component to fix the simulation part and the steel strand body. At this time, the fixation between the simulation component and the steel strand body is completed. At this time, under the action of the support base and the adjusting column, on the one hand, the matching degree between the simulation component and the steel strand body is improved, and on the other hand, support is provided for the simulation part and the steel strand body, thereby improving the accuracy of the operator's subsequent detection of the steel strand body.

[0027] Preferably, the limiting component includes a first limiting plate and a second limiting plate. The first limiting plate is arranged at one end of the simulation part away from the support base, and the second limiting plate is arranged on the side of the first limiting plate away from the simulation part. A first limiting hole adapted to the steel strand body is formed on the side of the first limiting plate close to the second limiting plate, and a second limiting hole adapted to the steel strand body is formed on the side of the second limiting plate close to the first limiting plate. The first limiting hole and the second limiting hole cooperate to form a limiting space for limiting the steel strand body.

[0028] By adopting the above technical solution, the operator adjusts the position between the simulation part and the steel strand body. When the steel strand body is inserted into the first limiting hole, the adjustment of the distance between the simulation part and the steel strand body is completed. The operator then connects the second limiting plate to the first limiting plate. At this time, the steel strand body is inserted into the second limiting hole.

[0031] 2. By setting up a protective cover, as well as a protective space and a filling space inside the protective cover, on the one hand, the possibility of damage and separation between the steel strand body and the connecting component is reduced. On the other hand, it makes it difficult for external liquids to come into contact with the steel strand body, thereby reducing the possibility of rust at the connection between the steel strand body and the connecting component. As a result, the connection stability between the steel strand body and the test stand is improved, enabling the operator to more accurately detect the accuracy of the steel strand body;

[0032] 3.

[0045] The following further describes the present application in detail with reference to the attached Figure 1-11 drawings.

[0046] Embodiment 1:

[0047] Embodiment 1 of the present application discloses a test tool for a strand used in a photovoltaic panel. Referring to Figure 1 and Figure 2 , a test tool for a strand used in a photovoltaic panel includes a test stand 2 for placing the strand body 1. The strand body 1 is connected to the photovoltaic panel 21 through a stabilizing assembly 3, and the strand body 1 is connected to the test stand 2 through a connecting assembly 4. Moreover, a protection assembly 5 for protecting the connecting assembly 4 and the strand body 1 is provided on the test stand 2, and a simulation assembly 6 for simulating the operation of the strand body 1 and the photovoltaic panel 21 is provided on the test stand 2.

[0048] Referring to Figure 2 and Figure 3, the connecting component 4 includes a connecting sleeve 41 and two opposite connecting clips 42. The connecting sleeve 41 is axially provided with a first connecting hole 411. The two opposite connecting clips 42 are arranged in the first connecting hole 411. The two connecting clips 42 are attached to each other to form a second connecting hole 421 for clamping the steel strand body 1. A number of clamping posts 422 are fixed on one side of the two opposite connecting clips 42 facing each other, and each clamping post 422 is clamped tightly with the steel strand body 1.

[0049] A detecting member 22 is fixed on the test stand 2. In the embodiment of the present application, the detecting member 22 is set as a pressure sensor. The protection component 5 includes a protection cover 51. The protection cover 51 is fixed to the pressure sensor through a fixing component 52. A protection groove 511 is opened on one side of the protection cover 51 close to the test stand 2. The connecting component 4 and the end of the steel strand body 1 far from the test stand 2 are both arranged in the protection groove 511, and the connecting sleeve 41 abuts against the fixing component 52.

[0050] In order to improve the protection ability of the protection cover 51 for the steel strand body 1 and the connecting component 4, a partition plate 53 is fixed in the protection groove 511. The partition plate 53 divides the protection groove 511 into a protection space 54 filled with a protection medium and a filling space 55 filled with a filling medium. The connecting component 4 is arranged in the protection space 54. A through hole 531 is opened on the partition plate 53. The steel strand body 1 passes through the through hole 531 and extends into the filling space 55. In the embodiment of the present application, the protection medium is set as grease. The grease provides protection for the steel strand body 1, so that the clamping posts 422 are not easy to damage the steel strand body 1, so as to improve the connection stability between the steel strand body 1 and the connecting component 4, and thus improve the connection stability between the steel strand body 1 and the test stand 2. The filling medium is set as a foaming agent. The foaming agent provides support and limit for the steel strand body 1, and at the same time further reduces the possibility of the outside liquid contacting the steel strand body 1.

[0051] In order to facilitate the operator to fill the foaming agent into the filling space 55, a filling hole 512 adjacent to and communicating with the filling space 55 is opened on the protection cover 51.

[0052] Refer to Figure 1 and Figure 2 , the fixing component 52 includes a fixing disc 521 and a fixing post 522. The fixing disc 521 is fixed on the side of the pressure sensor far from the test stand 2. The connecting sleeve 41 abuts against the fixing disc 521. The protection cover 51 abuts against the fixing disc 521. The fixing post 522 passes through the protection cover 51 and is inserted into the fixing disc 521. The fixing post 522 is threadedly connected with the fixing disc 521 and the protection cover 51. Under the action of the fixing disc 521 and the fixing post 522, it provides convenience for the operator to install the protection cover 51.

[0053] When the operator needs to fix the steel strand body 1 to the test stand 2, the operator passes the steel strand body 1 through the first connection hole 411. Then the operator uses a front clamping jack to clamp two connection clamping pieces 42 into the first connection hole 411, so that the two connection clamping pieces 42 are clamped tightly with the steel strand body 1. At the same time, each clamping column 422 is also clamped tightly with the steel strand body 1. Then the operator makes the connection sleeve 41 abut against the fixed disk 521. At this time, the installation between the steel strand body 1 and the test stand 2 is completed.

[0054] Then the operator puts the grease into the anti-slip space, and then tightly abuts the protective cover 51 against the fixed disk 521. Then the operator passes the fixing column 522 through the protective cover 51 and inserts it into the fixed disk 521, so that the fixing column 522 is threadedly connected with the protective cover 51 and the fixed disk 521. The operator fills the foaming agent into the filling space 55 from the filling hole 512. The foaming agent provides support and limit for the steel strand body, so that the steel strand body 1 is more stably connected with the test stand 2. At this time, under the action of the protective cover 51, it is not easy for the external liquid to contact the steel strand body 1, reducing the possibility of rust at the connection between the steel strand body 1 and the clamping column 422. At the same time, under the action of the filling space 55 filled with the filling medium, the possibility of the external liquid contacting the steel strand body 1 is further reduced, further improving the connection stability between the steel strand body 1 and the test stand 2, and thus further improving the accuracy of the operator's detection of the reliability of the steel strand body 1.

[0055] Refer to Figure 4 In order to improve the sealing performance of the protective cover 51, a ring groove 523 is provided on one side of the fixed disk 521 close to the protective cover 51. A sealing gasket 524 is embedded in the ring groove 523. In the embodiment of the present application, the sealing gasket 524 is made of silica gel, and the sealing gasket 524 abuts tightly against the protective cover. At this time, under the action of the sealing gasket 524, the sealing performance between the protective cover and the fixed disk 521 is improved, making it not easy for the external liquid to enter from the gap between the fixed disk 521 and the protective cover 51, thereby further reducing the possibility of rust of the steel strand body 1, and enabling the operator to more accurately detect the reliability of the steel strand body 1 subsequently.

[0056] Refer to Figure 2 and Figure 3 In order to reduce the possibility of wear between the connection sleeve 41 and the fixed disk 521, a corrugated spring 23 is provided between the connection sleeve 41 and the fixed disk 521. At this time, under the action of the corrugated spring 23, it is not easy for the connection sleeve 41 to collide violently with the fixed disk 521, reducing the possibility of separation between the connection sleeve 41 and the connection clamping piece 42, and making the connection clamping piece 42 abut tightly against the steel strand body 1 more stably, thereby improving the connection stability between the steel strand body 1 and the test stand 2.

[0057] Refer toFigure 5 and Figure 6 The stabilizing assembly 3 includes a first stabilizing block 31 and a second stabilizing block 32. A stabilizing hole 311 for the steel strand body 1 to pass through is formed in the first stabilizing block 31. The first stabilizing block 31 abuts against the photovoltaic panel 21. A stabilizing groove 312 is formed in the first stabilizing block 31. The second stabilizing block 32 is arranged in the stabilizing groove 312 and abuts tightly against the inner wall of the stabilizing groove 312. A fitting groove 321 adapted to the steel strand body 1 is formed on one side of the second stabilizing block 32 close to the first stabilizing block 31. The steel strand body 1 abuts against the inner wall of the fitting groove 321. The fitting groove 321 cooperates with the stabilizing hole 311 to form a fitting hole 33 for fitting the steel strand body 1.

[0058] A fixing member is provided on the first stabilizing block 31. In the embodiment of the present application, the fixing member is set as a bolt. The bolt passes through the first stabilizing block 31 and the second stabilizing block 32 and is fixed to the photovoltaic panel 21, and the bolt is in threaded connection with the first stabilizing block 31 and the second stabilizing block 32.

[0059] The operator clamps the first stabilizing block 31 on the steel strand body 1 so that the steel strand body 1 abuts against the inner wall of the stabilizing hole 311. Then the operator clamps the second stabilizing block 32 into the stabilizing groove 312 along the axis of the steel strand body 1. Then the operator passes the bolt through the first stabilizing block 31 and the second stabilizing block 32 and fixes it to the photovoltaic panel 21. At this time, the bolt squeezes the second stabilizing block 32 so that the second stabilizing block 32 abuts tightly against the steel strand body 1. After the bolt is clamped tightly with the first stabilizing block 31, the steel strand body 1 is clamped tightly with the inner walls of the fitting groove 321 and the stabilizing hole 311, improving the connection stability between the first stabilizing block 31 and the second stabilizing block 32 and the steel strand body 1, and at the same time improving the connection stability between the steel strand body 1 and the photovoltaic panel 21.

[0060] Refer to Figure 5 and Figure 6 To further improve the limiting ability of the first stabilizing block 31 and the second stabilizing block 32 on the steel strand body 1, a limiting block 322 is fixed on the second stabilizing block 32. A limiting groove 313 adapted to the limiting block 322 is formed on the inner wall of the stabilizing groove 312. When the operator uses the bolt to fix the first stabilizing block 31, the limiting block 322 further abuts tightly against the limiting groove 313, so that the second stabilizing block 32 further abuts tightly against the steel strand body 1, and at the same time the steel strand body 1 further abuts tightly against the inner wall of the stabilizing hole 311. And when the bolt fails, under the limiting action of the limiting block 322 and the limiting groove 313, the first stabilizing block 31 and the second stabilizing block 32 are not easily separated, so that the first stabilizing block 31 and the second stabilizing block 32 can stably connect the steel strand body 1 and the photovoltaic panel 21, which provides convenience for the operator to accurately detect the reliability of the steel strand body 1.

[0061] Reference Figure 5 and Figure 6 , a plurality of reinforcing protrusions 34 are fixed on the inner wall of the matching groove 321 and the inner wall of the stabilizing hole 311, and each reinforcing protrusion 34 is connected to the steel strand body 1. Under the action of the reinforcing protrusions 34, the contact area between the first stabilizing block 31 and the second stabilizing block 32 and the steel strand body 1 is increased, and the limiting ability of the first stabilizing block 31 and the second stabilizing block 32 on the steel strand body 1 is improved. And a friction-enhancing layer 314 is provided on the side of the first stabilizing block 31 away from the second stabilizing block 32. The friction-enhancing layer 314 is set as a plurality of friction-enhancing protrusions in the embodiment of the present application, and each friction-enhancing protrusion is tightly pressed against the photovoltaic panel 21. Under the action of the friction-enhancing protrusions, the contact area between the first stabilizing block 31 and the photovoltaic panel 21 is further increased, and the connection stability between the first stabilizing block 31 and the photovoltaic panel 21 is improved, thereby improving the connection stability between the steel strand body 1 and the photovoltaic panel 21, so as to improve the accuracy of the reliability of the operator when detecting the operation of the steel strand body 1.

[0062] Reference Figure 5 and Figure 6 In order to reduce the weight of the photovoltaic panel 21, the first stabilizing block 31, the second stabilizing block 32, the limit block 322, each reinforcement protrusion 34 and each friction-increasing protrusion are all made of aluminum alloy, and the first stabilizing block 31, the second stabilizing block 32 and the limit block 322 are all provided with weight-reducing holes 35, so that the steel strand can drive the photovoltaic panel 21 to move more stably, which provides convenience for the operator to control the simulation component 6 to simulate the work of the steel strand and the photovoltaic panel 21.

[0063] Reference Figure 7 The simulation component 6 includes a simulation part 61 and a support seat 62. The simulation part 61 is fixed on the support seat 62. The side of the simulation part 61 away from the support seat 62 is connected to the steel strand body 1 through the limit component 7. The support seat 62 is connected to the test frame 2 through the adjustment component 64. In the embodiment of the present application, the simulation part 61 is set as an electric cylinder, which is fixed to the support seat 62 by bolts, and the limit component 7 is fixed to the output end of the electric cylinder.

[0064] The adjustment component 64 includes a plurality of adjustment columns 641. In the embodiment of the present application, four adjustment columns 641 are provided. The four adjustment columns 641 are respectively fixed at the four corners of the support seat 62 by nuts. Four adjustment holes 24 are opened on the test frame 2 corresponding to the four adjustment columns 641. An adjustment column 641 is slid in each adjustment hole 24, and the end of the adjustment column 641 away from the support seat 62 is fixed to the test frame 2 by a nut.

[0065] The limiting component 7 includes a first limiting plate 71 and a second limiting plate 72. The first limiting plate 71 is fixed on the output end of the electric cylinder. A first limiting hole 711 adapted to the steel strand body 1 is formed on the side of the first limiting plate 71 away from the electric cylinder. The second limiting plate 72 is arranged on the side of the first limiting plate 71 away from the electric cylinder. A second limiting hole 721 adapted to the steel strand body 1 is formed on the side of the second limiting plate 72 close to the first limiting plate 71. The first limiting hole 711 and the second limiting hole 721 cooperate to form a limiting space 73 for limiting the steel strand body 1, and the first limiting plate 71 and the second limiting plate 72 are connected by bolts.

[0066] After the operator fixes the photovoltaic panel 21 to the steel strand body 1, the operator uses bolts to fix the electric cylinder to the support base 62, and then moves the support base 62 in the direction of the steel strand body 1. The movement of the support base 62 drives the movement of the adjusting column 641. When the first limiting plate 71 abuts against the steel strand body 1, the adjustment of the distance between the support base 62 and the steel strand body 1 is completed. At this time, the operator uses nuts to fix the adjusting column 641 to the test stand 2. Under the action of the adjusting column 641, it is convenient for the electric cylinder to stably control the movement of the steel strand body 1, thereby improving the accuracy of the operator's detection of the reliability of the steel strand body 1.

[0067] The operator then uses bolts to fix the second limiting plate 72 to the first limiting plate 71. At this time, the steel strand body 1 is located in the limiting space 73 formed by the first limiting hole 711 and the second limiting hole 721, thereby completing the connection between the electric cylinder and the steel strand body 1. Under the action of the first limiting plate 71 and the second limiting plate 72, the contact area between the electric cylinder and the steel strand body 1 is increased, so that the electric cylinder can more stably control the movement of the steel strand body 1, thereby improving the accuracy of the operator's detection of the reliability of the steel strand body 1.

[0068] After the operator fixes the steel strand body 1 to the electric cylinder, the operator starts the electric cylinder. The electric cylinder drives the first limiting plate 71 and the second limiting plate 72 to move up and down. The first limiting plate 71 and the second limiting plate 72 drive the steel strand body 1 to move up and down. The steel strand body 1 then drives the photovoltaic panel 21 to rotate to simulate the working state of the steel strand body 1 and the photovoltaic panel 21. The operator then observes the change value of the pressure sensor so that the operator can more intuitively detect the reliability of the steel strand body 1. At this time, the protection component 5 and the stabilizing component 3 both provide support and limitation for the steel strand body 1 and the photovoltaic panel 21, thereby improving the accuracy of the operator's detection of the reliability of the steel strand body 1.

[0069] The implementation principle of the first embodiment of this application is as follows: The operator uses the simulation part 61 to control the movement of the steel strand body 1 and the photovoltaic panel 21 to simulate the working states of the steel strand body 1 and the photovoltaic panel 21. During the simulation process, the adjusting component 64 provides support for the support base 62, enabling the simulation part 61 to drive the steel strand body 1 and the photovoltaic panel 21 to move relatively stably. At the same time, the protection component 5 provides support and protection for the steel strand body 1, making the connection between the steel strand body 1 and the test rack 2 not prone to rusting, and improving the connection stability between the steel strand body 1 and the test rack 2; the stabilizing component 3 provides support and limitation for the steel strand body 1 and the photovoltaic panel 21, reducing the possibility of separation between the steel strand body 1 and the photovoltaic panel 21, thereby improving the reliability and accuracy of the operator's detection of the working condition of the steel strand body 1.

[0070] Embodiment Two:

[0071] Refer to Figure 8 , the difference from the second embodiment of this application is that: in order to improve the stability when the operator adjusts the distance between the simulation part 61 and the steel strand body 1, the support base 62 is connected to the test rack 2 through a synchronization component 8. The synchronization component 8 includes an adjustment seat 81 and several synchronization columns 82. The adjustment seat 81 is arranged on the side of the support base 62 close to the test rack 2, and the adjustment seat 81 is fixed to the test rack 2 through a support frame 83. A number of synchronization slots 811 are formed on the side of the adjustment seat 81 close to the support base 62, and a synchronization column 82 is slidably connected to each of the synchronization slots 811. The end of the synchronization column 82 away from the adjustment seat 81 is connected to the support base 62, and an adjustment member 84 for controlling the synchronous movement of each synchronization column 82 is provided in the adjustment seat 81.

[0072] Refer to Figure 8 and Figure 9 , there is an adjustment space 85 between the adjustment seat 81 and the test rack 2, and a control slot 812 is formed on the side of the adjustment seat 81 close to the test rack 2, and the adjustment member 84 is arranged in the control slot 812.

[0073] Refer to Figure 10 and Figure 11 , a connection column 813 is rotatably connected in each synchronization slot 811 in the vertical direction, a relief groove 821 is formed in the vertical direction at the end of each synchronization column 82 close to the adjustment seat 81, and each connection column 813 is threadedly connected to the corresponding relief groove 821.

[0074] Refer to Figure 8 , Figure 9 and Figure 10, the adjusting member 84 includes a control rod 841 and a driving gear 842. The control rod 841 is arranged vertically and rotates in the control groove 812. The driving gear 842 is arranged in the control groove 812 and coaxially fixed on the control rod 841. Each connecting column 813 extends into the control groove 812 and coaxially fixes a driven gear 86, and each driven gear 86 meshes with the driving gear 842.

[0075] Refer to 8 and Figure 9 , in order to reduce the possibility of the separation between the driven gear 86 and the driving gear 842, two oppositely arranged limiting discs 87 are coaxially fixed on the connecting column 813. One of the limiting discs 87 is arranged in the synchronization groove 811 and abuts against the inner wall of the synchronization groove 811, and the other limiting disc 87 is arranged in the control groove 812 and abuts against the inner wall of the control groove 812.

[0076] When it is necessary to adjust the distance between the simulation member 61 and the steel strand body 1, the operator rotates the control rod 841. The control rod 841 drives the driving gear 842 to rotate. The driving gear 842 drives each driven gear 86 to rotate. The driven gear 86 drives the corresponding connecting column 813 to rotate. At this time, under the limiting action of the synchronization groove 811, the connecting column 813 drives the corresponding synchronization column 82 to move, realizing the function of the synchronous movement of each synchronization column 82, thereby improving the stability of the operator when adjusting the distance between the simulation member 61 and the steel strand body 1, and improving the stability of the simulation member 61 when controlling the movement of the steel strand body 1.

[0077] Refer to Figure 8 , in order to further improve the stability of the movement of the synchronization column 82, a dovetail slider 88 is fixed on each synchronization column 82, and a dovetail chute 814 is formed on the inner wall of the synchronization groove 811 corresponding to each synchronization column 82. During the rotation of the connecting column 813, the dovetail slider 88 and the dovetail chute 814 further provide a limit for the synchronization column 82, so that the connecting column 813 drives the corresponding synchronization column 82 to move more stably.

[0078] Refer to Figure 8 , in order to visually observe the levelness of the support base 62, a level 89 is fixed on each of the four side walls of the support base 62. At this time, under the action of the level 89, the operator can observe the levelness of the support base 62 to judge the position accuracy between the linear driving mechanism and the steel strand body 1.

[0079] Refer to Figure 10 , an adjusting plate 9 is slidably connected in the control groove 812. The control rod 841 is rotatably connected to the side of the adjusting plate 9 close to the test stand 2. The adjusting plate 9 is fixed to the adjusting seat 81 through a support member, and each connecting column 813 extends into the adjusting space 85 and coaxially fixes a rotating disc.

[0080] The support member includes support columns 91. Two opposite elongated holes 815 are vertically formed in the adjustment base 81, and both of the two elongated holes 815 communicate with the control groove 812. Two support columns 91 are provided and are respectively fixed on two opposite side walls of the adjustment plate 9, and the support columns 91 extend into the corresponding elongated holes 815 and slide along the elongated holes 815. The support columns 91 are fixed to the adjustment base 81 through nuts.

[0081] When the operator observes that the levelness of the support base 62 is deviated, the operator moves the control rod 841 in a direction away from the test stand 2. The control rod 841 drives the driving gear 842 and the adjustment plate 9 to move in a direction away from the test stand 2. The adjustment plate 9 drives the support columns 91 to move along the elongated holes 815. When the driving gear 842 is separated from the driven gear 86, the operator uses a nut to fix the support columns 91 to the adjustment base 81. At this time, the operator can rotate the corresponding rotating disk to control the rotation of the corresponding connecting column 813. The connecting column 813 drives the synchronous column 82 at the corresponding position to move, so that the support base 62 is in a relatively flat position, so that the simulation member 61 can more stably control the steel strand body 1.

[0082] The implementation principle of the second embodiment of this application is as follows: When the operator adjusts the distance between the simulation member 61 and the steel strand body 1, under the action of the synchronous assembly 8, the stability of the operator when moving the support base 62 is improved, thereby improving the stability of the operator when adjusting the position of the simulation member 61, facilitating the subsequent relatively stable control of the movement of the steel strand body 1 by the simulation member 61, and further improving the accuracy of the operator in detecting the strength of the steel strand body 1.

[0083] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
