Description

Technical Field

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

[0002] A cable tensile testing machine is a device that tests the maximum load-bearing capacity of a cable under static tensile conditions. During the use of this machine, a limiting structure is needed to fix the cable, thereby improving its effectiveness. For example: Chinese Patent Publication No. CN216560021U discloses a tensile strength testing device for power cable production, including a support column vertically fixed to the top of the ground, with an outer shell fixedly connected to the top of the support column, and a fixing strip fixedly installed inside the outer shell. This tensile strength testing device for power cable production, through the inclusion of a rubber buffer plate, prevents wear on the cable sheath when the top and bottom supports are fixing the power cable, and also prevents scratches on the cable sheath during testing. The inclusion of a telescopic rod and a limiting spring allows the device to test power cables of various sizes. Furthermore, the rubber buffer plate does not shift when the lifting cylinder moves the power cable. The inclusion of a turntable and connecting rod facilitates the fixing of the power cable to the testing device, and the device also prevents wear on the power cable when the moving supports are pulled during testing.

[0003] The existing technical solutions described above have the following drawbacks: when fixing the cable, it is fixed by a top bracket and fixing bolts; ordinary cable tensile testing machines do not provide good protection for operators when the cable breaks; and the replacement of the tensile sensor is not convenient enough. Therefore, this utility model provides a cable tensile testing machine to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a cable tensile testing machine to solve the problems mentioned in the background art, such as the poor protection of operators when the cable breaks due to the use of a top bracket and fixing bolts for fixing cables, and the inconvenience of replacing the tensile sensor.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cable tensile strength testing machine, comprising a housing, a cylinder fixedly installed on the right side inside the housing, and a mounting frame fixedly installed on the left side of the cylinder, a tension roller fixedly installed on the inner side of the left end of the mounting frame, and a cable body connected to the outer side of the tension roller, a connecting plate provided on the front side of the housing, and a fixing structure fixedly installed on the outer side of the connecting plate. A fixing rod is installed on the upper left side of the box, and a limit block is installed on the outer right side of the fixing rod. A connecting block is fixedly connected to the right side of the limit block, and a tension sensor is fixedly installed on the right side of the connecting block. A fixing ring is engaged with the right side of the tension sensor, and mounting plates are fixedly connected to the right side of the fixing ring and the lower inner side of the box. A limit structure is connected to the front side of the mounting plate.

[0006] Preferably, the fixing rod and the limiting block are connected by a thread, and the fixing rod is symmetrically distributed about the center line of the connecting block.

[0007] Preferably, the limiting block and the box are connected by a snap-fit ​​method, and the vertical cross-section between the limiting block and the connecting block forms a "π" shaped structure.

[0008] Preferably, the fixing structure includes a fixing plate, which is fixedly installed on the outer rear end of the connecting plate, and a spring is provided on the outer middle part of the fixing plate, and a moving rod is fixedly installed on the outer side of the spring.

[0009] Preferably, the cross-sectional shape of the fixing plate is an "L" shape, and the fixing plates are symmetrically distributed about the center line of the connecting plate.

[0010] Preferably, the fixed plate and the movable rod are connected in a sliding manner, and the movable rod and the box are connected in a snap-fit ​​manner.

[0011] Preferably, the limiting structure includes a movable block, which is installed on the inner and outer sides of the mounting plate, and a mounting rod is connected to the outer left end of the movable block. Furthermore, a mounting block is fixedly installed on the rear side of the movable block, and an anti-slip protrusion is fixedly installed on the rear side of the mounting block.

[0012] Preferably, the movable block and the mounting rod are connected by threads, which also serves to fix the mounting block.

[0013] Preferably, the anti-slip protrusion is connected to the cable body in a fitted manner, and the cable body is connected to the mounting plate in a snap-fit ​​manner.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the cable tensile testing machine facilitates the protection of testing operators, facilitates the limitation of the cable body, and facilitates the replacement of the tensile sensor; By placing the connecting plate at the front end of the enclosure, the connecting plate drives the fixing plate to engage and install on the outer front end of the enclosure. By releasing the moving rod, the spring drives the moving rod to slide inward, thereby causing the moving rod to slide inward on the middle side of the fixing plate, and then the moving rod to engage and connect on the outer front end of the enclosure. This facilitates the fixing of the connecting plate and helps to prevent injury to operators when the cable breaks. By engaging the cable body on the inside right side of the mounting plate, pushing the moving block backward causes the moving block to slide the mounting block backward inside the mounting plate. This causes the mounting block to bring the anti-slip protrusion into contact with the front end of the cable body, thereby clamping the cable body with the anti-slip protrusion and the mounting plate. Rotating the mounting rod causes it to be threaded on the front left end of the moving block, thus threading the mounting rod on the front side of the mounting plate, which facilitates the limiting and fixing of the cable body. By rotating the fixing rod, the fixing rod is threaded onto the upper left side of the box, thereby separating the fixing rod from the inside of the limiting block. Pulling the tension sensor to the right causes the tension sensor to slide the connecting block to the right, thereby causing the connecting block to separate the limiting block from the inside left side of the box, making it convenient to replace the tension sensor.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-6 This utility model provides a technical solution: a cable tensile testing machine, comprising: a cylinder 2 fixedly installed on the right side inside the housing 1, and a mounting frame 3 fixedly installed on the left side of the cylinder 2; a tension roller 4 fixedly installed on the inner side of the left end of the mounting frame 3, and a cable body 5 connected to the outer side of the tension roller 4; a connecting plate 12 provided on the front side of the housing 1, and a fixing structure fixedly installed on the outer side of the connecting plate 12; placing the connecting plate 12 at the front end of the housing 1, causing the connecting plate 12 to drive the fixing structure to be installed on the outer side of the front end of the housing 1, so that the fixing structure is connected on the outer side of the housing 1, facilitating the fixing of the connecting plate 12, thereby preventing injury to the operator when the cable breaks; activating the cylinder 2, causing the cylinder 2 to drive the mounting frame 3 to slide to the right, thereby causing the mounting frame 3 to drive the tension roller 4 to slide to the right, thus causing the tension roller 4 to stretch the cable body 5, facilitating tensile testing of the cable body 5. A fixing rod 7 is installed on the upper left side of the housing 1, and a limit block 9 is installed on the outer right side of the fixing rod 7. A connecting block 8 is fixedly connected to the right side of the limit block 9, and a tension sensor 10 is fixedly installed on the right side of the connecting block 8. A fixing ring 11 is engaged with the right side of the tension sensor 10. A mounting plate 6 is fixedly connected to both the right side of the fixing ring 11 and the lower inner side of the housing 1. A limit structure is connected to the front side of the mounting plate 6. The cable body 5 is installed on the right side inside the mounting plate 6, and the limit structure is pushed backward, so that the limit structure and the mounting plate 6 are aligned with the cable. The main body 5 is clamped to facilitate the limiting and fixing of the cable main body 5. The fixing rod 7 is rotated to connect to the upper left side of the box 1, thereby separating the fixing rod 7 inside the limiting block 9. The tension sensor 10 is pulled to the right, causing the tension sensor 10 to drive the connecting block 8 to slide to the right, thereby causing the connecting block 8 to drive the limiting block 9 to separate inside the box 1 on the left side. Then the tension sensor 10 is pulled down to separate the tension sensor 10 in the middle of the fixing ring 11, which facilitates the replacement of the tension sensor 10.

[0019] When using this cable tensile testing machine, specific details are as follows: Figure 1 , Figure 5 and Figure 6In this process, the cable body 5 is snapped into place on the right side inside the mounting plate 6. The moving block 16 is connected to the mounting rod 18 by a thread and fixes the mounting block 17. Pushing the moving block 16 backward causes the mounting block 17 to slide backward inside the mounting plate 6, thereby causing the mounting block 17 to bring the anti-slip protrusion 19 into contact with the front end of the cable body 5. The anti-slip protrusion 19 is connected to the cable body 5 by a close fit, and the cable body 5 is connected to the mounting plate 6 by a snap-fit, thereby clamping the cable body 5 with the anti-slip protrusion 19 and the mounting plate 6. Rotating the mounting rod 18 causes the mounting rod 18 to be threaded on the front left end of the moving block 16, thereby threading the mounting rod 18 on the front side of the mounting plate 6, which facilitates the limiting and fixing of the cable body 5. Specific examples Figure 1 , Figure 3 and Figure 4 In the process, the connecting plate 12 is placed at the front end of the housing 1. The fixed plate 13 has an "L" shaped cross-section and is symmetrically distributed about the center line of the connecting plate 12. The connecting plate 12 drives the fixed plate 13 to engage and install on the outer front end of the housing 1. The moving rod 15 is released, and the spring 14 drives the moving rod 15 to slide inward. The fixed plate 13 and the moving rod 15 are connected by sliding, and the moving rod 15 is connected to the housing 1 by engaging. This allows the moving rod 15 to slide inward from the middle side of the fixed plate 13, and then engage and connect on the outer front end of the housing 1, which facilitates the fixing of the connecting plate 12 and prevents injury to the operator when the cable breaks. The cylinder 2 is activated, which drives the mounting frame 3 to slide to the right, which in turn drives the tension roller 4 to slide to the right, thereby stretching the cable body 5 and facilitating tensile testing of the cable body 5. Specific examples Figure 1 and Figure 2 In the middle, rotate the fixing rod 7. The fixing rod 7 is connected to the limiting block 9 by a thread. The fixing rod 7 is symmetrically distributed about the center line of the connecting block 8. The fixing rod 7 is threaded on the upper left side of the box 1, so that the fixing rod 7 is separated inside the limiting block 9. The limiting block 9 is connected to the box 1 by a snap-fit. The vertical cross section between the limiting block 9 and the connecting block 8 forms a "π" shape. Pull the tension sensor 10 to the right, so that the tension sensor 10 drives the connecting block 8 to slide to the right, so that the connecting block 8 drives the limiting block 9 to separate inside the left side of the box 1. Then pull the tension sensor 10 down, so that the tension sensor 10 separates in the middle of the fixing ring 11, which facilitates the replacement of the tension sensor 10.
