[0002] Special equipment refers to equipment that involves life safety and is highly dangerous. Its management and use are subject to strict regulations and standards. Cables can exist as important components in special equipment. For example, in elevators, elevator cables are a key part to ensure the safe operation of elevators.

[0003] In order to fix the position of the cable during strength testing, a special equipment structural strength testing fixture was designed. This device drives the movable frame to slide by rotating the connecting plate, which in turn causes the two positioning clamping plates to slide relative to each other and fix the cable. This fixes the position of both ends of the cable, so that the data obtained during cable strength testing is more accurate. Summary of the Invention

[0004] The purpose of this invention is to provide a fixture for testing the structural strength of special equipment, which fixes the two ends of a cable in place so that the data obtained during cable strength testing is more accurate, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A fixture for testing the structural strength of special equipment includes a support platform: vertical support rods are fixedly connected to the left and right sides of the top of the support platform by bolts; horizontal support rods are fixedly connected to the top of the two vertical support rods; a support connecting plate is rotatably connected to the front side of the two vertical support rods; a movable frame is slidably connected to the surface of the horizontal support rod; a first rotating plate is rotatably connected to the top of the movable frame; a second rotating plate is rotatably connected to the top of the horizontal support rod; a rotating connecting plate is rotatably connected to the side of the movable frame opposite to the second rotating plate; the bottom end of the rotating connecting plate is rotatably connected to the surface of the support connecting plate; a positioning block is fixedly connected to the top of the horizontal support rod; and a positioning clamping plate is fixedly connected to the top of both the movable frame and the positioning block.

[0006] Preferably, the first rotating plate is located behind the positioning clamping plate, the second rotating plate is located behind the movable frame, and the positioning block is located in front of the movable frame.

[0007] Preferably, rubber force strips are fixedly connected to opposite sides of the positioning clamping plate, and a long round rod is fixedly connected between the two supporting connecting plates.

[0008] Preferably, the top of the support platform is fixedly connected to two positioning support plates by bolts, and the top of each of the two positioning support plates is rotatably connected to a cylinder.

[0009] Preferably, the output end of each cylinder is fixedly connected to a rectangular frame, and the surface of the long cylindrical rod is slidably connected to the inner cavity of the rectangular frame.

[0010] Preferably, the bottom of the movable frame is rotatably connected to a rotating round rod, the surface of which is slidably connected to the bottom of the transverse support rod, and the left and right sides of the top of the support platform are fixedly connected to perforated support plates by bolts.

[0011] The beneficial effects of this utility model are: 1. This utility model uses a starting cylinder to pull and drive the support connecting plate to deflect, which in turn causes the first rotating plate to push the movable frame to slide. At this time, under the action of the positioning block and the positioning clamping plate, the cable is clamped and fixed, so that the two ends of the cable are fixed in position, so that the data obtained when the cable is tested for strength is more accurate. 2. By setting a rectangular frame, this utility model can increase the range of motion of the long round rod, so that when the cylinder pulls the long round rod to drive the support connecting plate to deflect, it can avoid the situation where the support connecting plate cannot deflect normally due to insufficient range of motion of the long round rod. 3. By setting up a rotating round rod, this utility model can reduce the friction between the movable frame and the horizontal support rod, thus preventing the movable frame from being blocked during its sliding motion on the surface of the horizontal support rod.

[0014] In the following description, embodiments of the present invention for a fixture for testing the structural strength of special equipment will be described with reference to the accompanying drawings. Example

[0015] Figure 1-4 This invention illustrates an embodiment of a fixture for testing the structural strength of special equipment, comprising: a support platform 1; vertical support rods 2 are bolted to the left and right sides of the top of the support platform 1; horizontal support rods 3 are fixedly connected to the top of each of the two vertical support rods 2; support connecting plates 4 are rotatably connected to the front of each of the two vertical support rods 2; a movable frame 5 is slidably connected to the surface of the horizontal support rod 3; a first rotating plate 6 is rotatably connected to the top of the movable frame 5; a second rotating plate 7 is rotatably connected to the top of the horizontal support rod 3; a rotating connecting plate 8 is rotatably connected to the side of the movable frame 5 opposite to the second rotating plate 7; the bottom end of the rotating connecting plate 8 is rotatably connected to the surface of the support connecting plate 4; a positioning block 9 is fixedly connected to the top of the horizontal support rod 3; and the movable frame 5 and the positioning block are also included. Positioning clamping plates 10 are fixedly connected to the top of each of the 9. The first rotating plate 6 is located behind the positioning clamping plate 10, the second rotating plate 7 is located behind the movable frame 5, and the positioning block 9 is located in front of the movable frame 5. Rubber force strips 11 are fixedly connected to the opposite sides of the two positioning clamping plates 10. A long round rod 12 is fixedly connected between the two support connecting plates 4. A rectangular frame 15 is fixedly connected to the output end of each of the two cylinders 14. The surface of the long round rod 12 is slidably connected to the inner cavity of the rectangular frame 15. By setting the rectangular frame 15, the range of motion of the long round rod 12 can be increased, so that when the cylinder 14 pulls the long round rod 12 to drive the support connecting plate 4 to deflect, the support connecting plate 4 will not be unable to deflect normally due to insufficient range of motion of the long round rod 12. Example

[0016] Figure 1-4This invention illustrates an embodiment of a fixture for testing the structural strength of special equipment, comprising: a support platform 1; vertical support rods 2 are bolted to the left and right sides of the top of the support platform 1; horizontal support rods 3 are bolted to the top of each of the two vertical support rods 2; support connecting plates 4 are rotatably connected to the front of each of the two vertical support rods 2; a movable frame 5 is slidably connected to the surface of the horizontal support rod 3; a first rotating plate 6 is rotatably connected to the top of the movable frame 5; a second rotating plate 7 is rotatably connected to the top of the horizontal support rod 3; a rotating connecting plate 8 is rotatably connected to the side of the movable frame 5 opposite to the second rotating plate 7; and the bottom end of the rotating connecting plate 8 is rotatably connected to the surface of the support connecting plate 4; the horizontal support rods 3... A positioning block 9 is fixedly connected to the top of the movable frame 5. A positioning clamping plate 10 is fixedly connected to the top of both the movable frame 5 and the positioning block 9. Two positioning support plates 13 are fixedly connected to the top of the support platform 1 by bolts. A cylinder 14 is rotatably connected to the top of each of the two positioning support plates 13. A rotating round rod 16 is rotatably connected to the bottom of the movable frame 5. The surface of the rotating round rod 16 is slidably connected to the bottom of the transverse support rod 3. By setting the rotating round rod 16, the friction between the movable frame 5 and the transverse support rod 3 can be reduced, and the movable frame 5 can avoid obstruction during the sliding process on the surface of the transverse support rod 3. Perforated support plates 17 are fixedly connected to the left and right sides of the top of the support platform 1 by bolts.

[0017] Working principle: When using this utility model, the user passes one end of the cable through the round hole on the surface of the perforated support plate 17, so that the surface of the cable passes over the top of the transverse support rod 3. Then, the cylinder 14 is activated to drive the rectangular frame 15 to slide, which in turn pulls the long round rod 12 to slide, and drives the support connecting plate 4 to deflect. This causes the support connecting plate 4 to pull the first rotating plate 6 and the second rotating plate 7 to rotate synchronously. Then, the first rotating plate 6 pushes the movable frame 5 to slide on the surface of the transverse support rod 3. At this time, under the action of the positioning block 9 and the positioning clamping plate 10, the cable passing over the top of the transverse support rod 3 is clamped and fixed, so that the position of the cable is fixed, and the data obtained when the cable is tested for strength is more accurate.

[0018] In summary, this fixture for testing the structural strength of special equipment works by using a starting cylinder 14 to pull and deflect the supporting connecting plate 4, which in turn causes the first rotating plate 6 to push the movable frame 5 to slide. At this time, under the action of the positioning block 9 and the positioning clamping plate 10, the cable is clamped and fixed, thus fixing the positions of both ends of the cable and obtaining more accurate data when testing the cable strength.
