[0002] With the continuous development of society and the continuous progress of science and technology, the technology related to railway insulator testing is also constantly improving. During the production of railway insulators, tensile testing machines are needed to perform tensile tests on them to ensure the performance and quality of railway insulators.

[0003] Currently, when using a tensile testing machine to test the tensile strength of railway insulators, the insulators will break when the tensile force reaches its limit, resulting in fragments flying everywhere. This makes it inconvenient to collect the broken insulators, reduces safety performance, and is detrimental to the use of the tensile testing machine. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology: when using a tensile testing machine to test the tensile strength of railway insulators, the railway insulators will break when the tensile force reaches its limit, resulting in fragments of railway insulators flying everywhere. This makes it inconvenient to collect the broken railway insulators, has low safety performance, and is not conducive to the use of the tensile testing machine. Therefore, a railway insulator tensile testing machine is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A railway insulator tensile testing machine includes a machine body, a collection box inside the machine body, a first arc-shaped plate fixedly installed inside the machine body, a second arc-shaped plate slidably connected inside the machine body, sliding rods fixedly connected to both sides of the second arc-shaped plate, arc-shaped openings for connecting the corresponding sliding rods on both sides of the machine body, and a limit ring fixedly connected to each sliding rod. Both sides of the machine body are rotatably connected to T-shaped rotating shafts. The upper end of each T-shaped rotating shaft is fixedly connected to the corresponding sliding rod. Two fixing plates and a U-shaped plate are fixedly connected to the back of the machine body. A round rod is rotatably connected to each fixing plate. A transmission wheel is fixedly connected to each round rod and each T-shaped rotating shaft. Multiple transmission wheels are connected by two transmission belts.

[0006] Preferably, the limiting component includes a handwheel fixedly installed on the outside of the rectangular rod, the outer surface of the handwheel is provided with anti-slip texture, a plurality of limiting shafts are fixedly connected to one side surface of the handwheel, and a plurality of through holes for connecting the limiting shafts are provided on the U-shaped plate.

[0008] Preferably, a first spring is fixedly connected to one of the round rods, and the first spring is fixedly connected to the handwheel.

[0009] Preferably, both the first arc-shaped plate and the second arc-shaped plate have buffer plates connected to them by multiple buffer springs inside, and the cross-section of the buffer plates is arc-shaped.

[0010] Preferably, a V-shaped baffle is fixedly connected to one inner wall of the machine body, and an inclined baffle is fixedly connected to the collection box.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The enclosure and buffer structure of the first and second arc-shaped plates effectively blocks and weakens the splashing of debris, avoiding injury to personnel or equipment.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0016] Reference Figures 1-5 A railway insulator tensile testing machine includes a body 1, a collection box 2 inside the body 1, the collection box 2 being slidably disposed inside the body 1 for easy removal and cleaning of debris, a first arc plate 13 fixedly installed inside the body 1, and a second arc plate 12 slidably connected inside the body 1, the first arc plate 13 and the second arc plate 12 cooperating to enclose the railway insulator, slide rods 4 being fixedly connected to both sides of the second arc plate 12, and arc-shaped openings for connecting the corresponding slide rods 4 being opened on both sides of the body 1, the slide rods 4 sliding along the arc-shaped openings, and a limit ring 11 being fixedly connected to each slide rod 4, the surface of the limit ring 11 being in contact with the outer surface of the body 1.

[0017] Both sides of the body 1 are rotatably connected to T-shaped rotating shafts 3. The upper end of each T-shaped rotating shaft 3 is fixedly connected to the corresponding sliding rod 4. The rotation of the T-shaped rotating shaft 3 drives the sliding rod 4 to slide, thereby realizing the opening and closing of the second arc plate 12. Two fixed plates 6 and a U-shaped plate 7 are fixedly connected to the back of the body 1. A round rod 9 is rotatably connected to each fixed plate 6. A transmission wheel is fixedly connected to each round rod 9 and each T-shaped rotating shaft 3. Multiple transmission wheels are connected by two transmission belts 10. The two round rods 9 are connected by a rectangular rod 16. The two ends of the rectangular rod 16 are slidably connected to the two round rods 9 respectively to ensure that the round rods 9 on both sides rotate synchronously. A limit component is provided on the rectangular rod 16.

[0018] The limiting assembly includes a handwheel 8 fixedly installed on the outside of a rectangular rod 16. The outer surface of the handwheel 8 is provided with anti-slip texture. Multiple limiting shafts 18 are fixedly connected to one side surface of the handwheel 8. Multiple through holes for connecting the limiting shafts 18 are opened on the U-shaped plate 7. The limiting shafts 18 can be inserted into the through holes to fix the angle of the handwheel 8. A plug shaft 19 is slidably connected to one side of the U-shaped plate 7. Each limiting shaft 18 has a slot for connecting the plug shaft 19 on one side. The plug shaft 19 can be inserted into the slot to prevent the limiting shaft 18 from disengaging from the through hole, further locking the angle of the handwheel 8.

[0019] A first spring 17 is fixedly connected to one of the round rods 9. The first spring 17 is fixedly connected to the handwheel 8. The interior of the first arc plate 13 and the second arc plate 12 are connected to a buffer plate 20 by multiple buffer springs 5. The cross-section of the buffer plate 20 is arc-shaped. The two ends of each buffer spring 5 are fixedly connected to the buffer plate 20 and the first arc plate 13 or the second arc plate 12, respectively. When the fragments hit the buffer plate 20, the elasticity of the buffer springs 5 ​​can play a buffering role. A V-shaped baffle 14 is fixedly connected to one side of the inner wall of the body 1. An inclined baffle 15 is fixedly connected to the collection box 2. The V-shaped baffle 14 and the inclined baffle 15 can guide the fragments to fall into the collection box 2, so as to achieve centralized collection of fragments.

[0020] In this invention, during testing, the insertion shaft 19 is pulled outward to disengage it from the slot. Under the elastic force of the first spring 17, the rectangular rod 16 slides, and all the limiting shafts 18 disengage from the through hole. Then, the handwheel 8 is rotated, which drives the sliding rod 4 to slide along the arc-shaped opening through the rectangular rod 16, the round rod 9, the transmission belt 10, and the T-shaped rotating shaft 3, pulling the second arc plate 12 outward. After the insulator is placed inside the machine body 1, the second arc plate 12 is closed in the same way. The machine body 1 is equipped with a hydraulic cylinder, a tension sensor, and a clamping mechanism (which has been disclosed in the document CN217132813U, and its working principle is not described in detail). These components can be used to test the tension of the insulator. When it breaks, the fragments are blocked by the first arc plate 13, the second arc plate 12, and the buffer plate 20. The buffer spring 5 absorbs the impact, and the fragments are guided by the V-shaped baffle 14 and slide down the inclined baffle 15 to the collection box 2 for centralized collection. After the test, the collection box 2 is pulled out to clean the internal fragments.

For example, they can refer to fixed connection, detachable connection, or integral connection; they can refer to mechanical connection or electrical connection; they can refer to direct connection or indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
