Description

Technical Field

[0001] This utility model relates to an elevator wire rope testing device, belonging to the field of elevator equipment testing technology. Background Technology

[0002] After elevator wire ropes are manufactured, they need to undergo tension testing to ensure the safety performance of the elevator. Existing tension testing devices usually involve cutting a section of the wire rope from the reel and clamping both ends of it. One clamped end is connected to a tensioning mechanism, and the other end is connected to a tension gauge. The tensioning mechanism pulls one end of the wire rope, and the tension gauge measures the tension of the wire rope.

[0003] However, this structure can only test the tension of this section of the wire rope, and cannot test the tension of the entire coil of wire rope, so the test results are not accurate enough. Utility Model Content

[0004] This invention provides an elevator wire rope detection device to solve the problems existing in the background art.

[0005] This utility model relates to an elevator wire rope testing device, including a testing frame. A tension gauge is hinged to one end of the top of the testing frame, and a sliding plate is hinged to the other end of the tension gauge. A second sliding plate is provided above the other end of the testing frame. Both the first and second sliding plates have sliders at their bottoms, and horizontal slide rails are provided at the bottom of the sliders. A tensioning mechanism is connected to the side of the second sliding plate away from the first sliding plate. A coaxial semi-circular fixed support is fixed in the middle of the top of both the first and second sliding plates. A fixed pressure sleeve that cooperates with the two fixed supports to press the wire rope is provided above the two fixed supports. A breaker and a take-up reel are rotatably installed on the left and right sides of the testing frame, respectively.

[0006] As a preferred embodiment, the tension mechanism includes a hydraulic cylinder fixed to the testing frame, with the piston rod end of the hydraulic cylinder fixedly connected to the slide plate, and the tension is provided by the contraction of the hydraulic cylinder.

[0007] As a preferred embodiment, both the front and rear outer walls of the fixed support and the fixed pressure sleeve are provided with connecting flanges, and the upper and lower connecting flanges are provided with locking bolts to conveniently press and fix the two ends of the wire rope of the section being tested.

[0008] As a preferred option, the inner walls of the fixed support and the fixed pressure sleeve are provided with anti-slip ridges for better anti-slip performance.

[0009] As a preferred embodiment, the inner holes of the breaker and rewinder are provided with support shafts, and the two ends of the support shafts are detachably connected to rotating shafts. The rotating shafts are rotatably mounted with bearing seats, and the bottom of the bearing seats is fixed with a bracket. The bottom of the front and rear brackets is fixed with a front-to-back movable slide plate, and the bottom of the front-to-back movable slide plate is fixed with a movable slider. The bottom of the movable slider is connected with a movable slide rail, and the bottom of the movable slide rail is fixed with a base frame. The bottoms of the breaker and rewinder can move back and forth, and the front and back positions of the breaker and rewinder can be adjusted according to the winding position of the breaker and rewinder.

[0010] As a preferred embodiment, a gap is provided between the rotating shaft and the support shaft, and a connecting sleeve is provided between the rotating shaft and the support shaft. The connecting sleeve is composed of two semi-circular sleeves, and a fixing flange is provided on the outer side wall of the two semi-circular sleeves.

[0011] As a preferred embodiment, a limiting connection boss is provided on the inner wall of one of the semicircular sleeves, and a limiting connection groove that mates with the limiting connection boss is provided on the outer wall of the rotating shaft and the support shaft, so that the rotating shaft and the support shaft can be better synchronized and prevent relative rotation.

[0012] This utility model has the following beneficial effects:

[0013] The two ends of the wire rope being tested are pressed by the fixed support sleeves and fixed pressure sleeves on the first and second slide plates, respectively. Then, the tension of the wire rope is tested in sections by the tension mechanism and tension gauge. With the help of the splitting and winding reels on the left and right sides, the tension of the entire wire rope can be tested in sections, which is more accurate and more practical.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] Example 1, such as Figures 1 to 4 As shown, this utility model is an elevator wire rope testing device, including a testing frame 4. A tension gauge 8 is hinged to one end of the top of the testing frame 4. The tension gauge 8 is a high-strength digital display tension gauge. A sliding plate 6 is hinged to the other end of the tension gauge 8. A second sliding plate 3 is provided above the other end of the testing frame 4. A slider is provided at the bottom of both the first sliding plate 6 and the second sliding plate 3. A horizontal slide rail 5 is provided at the bottom of the slider. A tensioning mechanism is connected to the side of the second sliding plate 3 away from the first sliding plate 6. A coaxial semi-circular fixed support sleeve 10 is fixed in the middle of the top of both the first sliding plate 6 and the second sliding plate 3. A fixed pressure sleeve 7 is provided above the two fixed support sleeves 10 to cooperate with and press the wire rope. A breaker 16 and a take-up 1 are rotatably installed on the left and right sides of the testing frame 4, respectively.

[0021] During operation, the breaker reel 16, fully wound with wire rope, is rotated and installed on the left side of the testing frame 4, while the empty take-up reel 1 is installed on the right side of the testing frame 4. Then, the head of the wire rope on the breaker reel 16 is pulled out and fixed to the fixed support sleeve 10 and fixed pressure sleeve 7 on the slide plate 2 3. Then, the other end of the test section of the wire rope is fixed using the fixed support sleeve 10 and fixed pressure sleeve 7 on the slide plate 1 6. Then, the tensioning mechanism applies force, and the wire rope in the test section is tensioned. The tension gauge 8 detects the tension of this section. When the tension value reaches the required test value and the wire rope does not break, this section of the wire rope is qualified. Then, the fixed support sleeve 10 and fixed pressure sleeve 7 are released to test the next section of the wire rope. The previous section of the wire rope is wound onto the take-up reel 1 until the wire rope on the entire breaker reel 16 has been tested.

[0022] Example 2, based on Example 1, the tension mechanism includes a hydraulic cylinder 2 fixed on the testing frame 4, and the piston rod end of the hydraulic cylinder 2 is fixedly connected to the slide plate 3.

[0023] Both the front and rear outer walls of the fixed support sleeve 10 and the fixed pressure sleeve 7 are provided with connecting flanges 11, and locking bolts 17 are provided on the upper and lower connecting flanges 11. When replacing the wire rope of the test section, the locking bolts 17 do not need to be completely removed.

[0024] The inner walls of the fixed support sleeve 10 and the fixed pressure sleeve 7 are provided with anti-slip ridges.

[0025] A support shaft 18 is provided in the inner hole of the breaker 16 and the take-up 1. A rotating shaft 15 is detachably connected to both ends of the support shaft 18. A bearing seat is rotatably mounted on the rotating shaft 15. A bracket 9 is fixed to the bottom of the bearing seat. A front-to-back sliding plate 14 is fixed to the bottom of the front-to-back sliding plate 9. A movable slider is fixed to the bottom of the front-to-back sliding plate 14. A movable slide rail 13 is connected to the bottom of the movable slider. A base frame 12 is fixed to the bottom of the movable slide rail 13. During testing, as the wire rope is broken and wound, the front-to-back position of the breaker 16 and the take-up 1 can be moved accordingly, ensuring that the wire rope outside the fixed support sleeve 10 and the fixed pressure sleeve 7 remains as horizontal as possible with the wire rope in the test section, preventing interference with the test and improving the winding effect.

[0026] A gap is provided between the rotating shaft 15 and the support shaft 18. A connecting sleeve 19 is provided between the rotating shaft 15 and the support shaft 18. The connecting sleeve 19 is composed of two semi-circular sleeves. A fixing flange 22 is provided on the outer wall of the two semi-circular sleeves. A fastening bolt 21 is provided on the fixing flange 22. The outer side of the support shaft 18 is provided with anti-slip ridges.

[0027] One of the semicircular sleeves has a limiting connecting boss 20 on its inner wall, and the outer walls of the rotating shaft 15 and the support shaft 18 have limiting connecting grooves that mate with the limiting connecting boss 20. When installing the breaker 16 and the take-up reel 1, the support shaft 18 is inserted into the inner holes of the breaker 16 and the take-up reel 1, and then the support shaft 18 is aligned between the front and rear rotating shafts 15. Then, the two corresponding semicircular sleeves are fastened to the connection between the rotating shaft 15 and the support shaft 18, and the limiting connecting boss 20 is inserted into the limiting connecting groove. Finally, the fastening bolt 21 is tightened.
