Description

Technical Field

[0001] This utility model relates to the field of elevator steel belt testing technology, and more specifically, to a non-destructive testing device for elevator traction steel belts. Background Technology

[0002] With the booming development of the elevator industry, more and more elevators are using traction steel belts to replace traditional steel wire ropes as the traction medium. The traction steel belt consists of an internal set of solidified metal skeletons and a wear-resistant rubber sleeve tightly wrapped around the outside of the metal skeletons. After processing and forming, it achieves the required composite properties of tensile strength, flexibility and wear resistance. The steel belt needs to be tested before it is put into use.

[0003] A search revealed that Chinese Patent CN211846757U discloses an elevator steel strip detection device, comprising a support plate for sliding the steel strip to be detected. Two linkage blocks are provided on the upper side wall of the support plate, and electric cylinders are fixedly connected to the upper side walls of both linkage blocks. A device plate is slidably connected to the ends of the output shafts of the two electric cylinders. A detection device is fixedly connected to the lower side wall of the device plate. Reference plates are fixedly connected to the side walls of the two linkage blocks on the same side, and each of the reference plates has a groove on its side wall that mates with the steel strip to be detected. This invention facilitates the detection of steel strips of different widths, improving applicability. It allows observation of the surface wear and tear of the steel strip and the width changes of the stretching on both sides, thereby improving the comprehensiveness and diversity of the detection. It also allows adjustment of the detection device and the steel strip to achieve a better detection distance, thus improving the detection accuracy. However, the existing technology has the following shortcomings in use:

[0004] The distance between the two linkage blocks needs to be manually adjusted by the staff, and nuts need to be tightened at the end of the locking bolts to accommodate steel strips of different widths. The manual adjustment method is not only time-consuming and labor-intensive, affecting work efficiency, but also increases the labor intensity of the staff, making it less practical.

[0005] Therefore, there is an urgent need for a non-destructive testing device for elevator traction steel belts to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to address the problem that the current method requires manual adjustment of the distance between two linkage blocks by workers, and the use of nuts to tighten the locking bolts to accommodate steel strips of different widths. This manual adjustment method is not only time-consuming and labor-intensive, affecting work efficiency, but also increases the labor intensity of workers and has low practicality.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A non-destructive testing device for elevator traction steel belts is proposed to improve the above-mentioned problems.

[0009] The application is as follows:

[0010] A non-destructive testing device for elevator traction steel belts includes a workbench with a horizontally mounted base plate fixedly connected to it. A first electric push rod is fixedly connected to the center of the top of the base plate, and a push plate is fixedly connected to the push rod end of the first electric push rod. A sliding groove is formed on the lower surface of the workbench, and symmetrically distributed connecting sliders are slidably connected within the groove. Transmission plates are hinged to both ends of the push plate, and the end of the transmission plate away from the push plate is hinged to the connecting slider. A U-shaped rod is fixedly connected to the connecting slider, and an L-shaped block is fixedly connected to the other end of the U-shaped rod. A guide pulley is rotatably connected to the upper surface of the L-shaped block. A connecting frame is fixedly connected to the top of the workbench, and a second electric push rod is fixedly connected to the center of the lower surface of the connecting frame. A mounting plate is fixedly connected to the push rod end of the second electric push rod, and a flaw detector is mounted on the bottom of the mounting plate.

[0011] As a preferred technical solution of this application, the front of the connecting frame is provided with a switch group, and the first electric push rod and the second electric push rod are both electrically connected to the switch group.

[0012] As a preferred technical solution of this application, the top of the mounting plate is fixedly connected with guide rods symmetrically distributed with respect to the second electric push rod, and the guide rods movably pass through the connecting frame.

[0013] As a preferred technical solution of this application, the flaw detector is located directly above the center of the top of the workbench.

[0014] As a preferred technical solution of this application, the L-shaped block is fitted to the worktable.

[0015] As a preferred technical solution of this application, the push plate is parallel to the base plate.

[0016] As a preferred technical solution of this application, the bottom of the workbench is fixedly connected with symmetrically distributed support plates.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the scheme of this application:

[0019] 1. The first electric push rod is activated by the switch group, which drives the push plate to move downward. During the downward movement of the push plate, the two transmission plates drive the two connecting sliders to slide in the groove, bringing the two connecting sliders closer together. The two U-shaped rods follow the movement of the two connecting sliders, reducing the distance between the two L-shaped blocks and the distance between the two guide pulleys. The two guide pulleys are adjusted to the appropriate position according to the required width of the steel strip. This method saves time and effort, improves work efficiency, and reduces the labor intensity of workers. It solves the problem that the existing technology requires workers to manually adjust the distance between the two linkage blocks and tighten nuts on the end of the locking bolts to accommodate steel strips of different widths. This manual adjustment method is not only time-consuming and labor-intensive, affecting work efficiency, but also increases the labor intensity of workers and has low practicality.

[0020] 2. Start the second electric push rod through the switch group. The second electric push rod will drive the mounting plate to move down, adjusting the flaw detector to a suitable height to facilitate subsequent inspection of the steel strip. Attached Figure Description

[0032] like Figure 1-4As shown, this embodiment proposes a non-destructive testing device for elevator traction steel belts, including a workbench 1. A horizontally arranged base plate 2 is fixedly connected to the workbench 1. A first electric push rod 3 is fixedly connected to the top center of the base plate 2. A push plate 4 is fixedly connected to the push rod end of the first electric push rod 3. When the first electric push rod 3 is activated, the push plate 4 is moved downwards. A groove 5 is provided on the lower surface of the workbench 1. Symmetrically distributed connecting sliders 6 are slidably connected in the groove 5. Transmission plates 7 are hinged to both ends of the push plate 4. The end of the transmission plate 7 away from the push plate 4 is hinged to the connecting slider 6. During the downward movement of the push plate 4, the two transmission plates 7 drive the two connecting sliders 6 to slide in the groove 5, causing the two connecting sliders 6 to move closer to each other. A U-shaped rod 8 is fixedly connected, and an L-shaped block 9 is fixedly connected to the other end of the U-shaped rod 8. A guide pulley 10 is rotatably connected to the upper surface of the L-shaped block 9. The two U-shaped rods 8 move with the two connecting sliders 6 respectively, so that the distance between the two L-shaped blocks 9 is reduced, and the distance between the two guide pulleys 10 is also reduced. A connecting frame 11 is fixedly connected to the top of the workbench 1. The two guide pulleys 10 are adjusted to a suitable position according to the width of the steel strip to be inspected, and then the steel strip is placed between the two guide pulleys 10. The steel strip is limited by the two guide pulleys 10. A second electric push rod 12 is fixedly connected to the center of the lower surface of the connecting frame 11. A mounting plate 13 is fixedly connected to the push rod end of the second electric push rod 12. A flaw detector 14 is installed at the bottom of the mounting plate 13.

[0033] like Figure 2 and Figure 4 As shown, the front of the connecting frame 11 is provided with a switch group 15. The first electric push rod 3 and the second electric push rod 12 are both electrically connected to the switch group 15. The first electric push rod 3 and the second electric push rod 12 are started by controlling the switch group 15.

[0034] like Figure 4 As shown, the top of the mounting plate 13 is fixedly connected with guide rods 16 symmetrically distributed with respect to the second electric push rod 12. The guide rods 16 movably pass through the connecting frame 11. When the mounting plate 13 is moved down by the second electric push rod 12, the two guide rods 16 guide the mounting plate 13 and adjust the flaw detector 14 to a suitable height.

[0035] like Figure 2 As shown, the flaw detector 14 is located directly above the center of the top of the workbench 1.

[0036] like Figure 2 As shown, the L-shaped block 9 is in contact with the worktable 1.

[0037] like Figure 2 and Figure 4 As shown, the push plate 4 is parallel to the base plate 2.

[0038] like Figure 1 As shown, the bottom of the workbench 1 is fixedly connected with symmetrically distributed support plates 17, which support the workbench 1.

[0039] Specifically, when using this elevator traction steel belt non-destructive testing device: the operator activates the first electric push rod 3 via switch group 15. The first electric push rod 3 drives the push plate 4 downwards. During the downward movement of the push plate 4, the two transmission plates 7 drive the two connecting sliders 6 to slide within the slide groove 5, bringing the two connecting sliders 6 closer together. The two U-shaped rods 8 follow the movement of the two connecting sliders 6, reducing the distance between the two L-shaped blocks 9. The distance between the two guide pulleys 10 also decreases accordingly, depending on the width of the steel belt to be tested. The two guide pulleys 10 are adjusted to a suitable position, and then the steel strip is placed between the two guide pulleys 10. The steel strip is limited by the two guide pulleys 10. Then, the second electric push rod 12 is activated by the switch group 15. The second electric push rod 12 drives the mounting plate 13 to move down. The mounting plate 13 is guided by the two guide rods 16. The flaw detector 14 is adjusted to a suitable height and the flaw detector 14 is used to perform flaw detection on the steel strip. The flaw detector 14 in this application is model TCK.W-GD3060.
