Description

Technical Field

[0001] This utility model relates to the field of steel strip inspection technology, and in particular to an elevator steel strip flaw detector. Background Technology

[0002] With the evolution of elevator technology, flat composite steel belts have gradually replaced traditional steel wire ropes due to their advantages such as small size, good flexibility, and smooth operation. They are widely used in the traction systems of new elevators. However, similar to steel wire ropes, steel belts can also cause safety hazards due to fatigue, wear, internal steel wire breakage, or external damage during long-term use. Therefore, regular and effective non-destructive testing of elevator steel belts is an important preventive measure to ensure the safe operation of elevators.

[0003] Currently, when faced with differences in the width specifications of steel strips used in different elevator models, the fixed testing chamber of existing flaw detectors is difficult to adapt to this change, and various testing fixtures are needed for different sizes. Therefore, it is necessary to design an elevator steel strip flaw detector. Utility Model Content

[0004] The purpose of this invention is to provide an elevator steel strip flaw detector to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An elevator steel strip flaw detector includes a mounting plate. A first fixing plate is fixedly mounted on the top right side of the mounting plate, and a second fixing plate is provided at the bottom right side of the mounting plate. There is a gap between the first fixing plate and the second fixing plate. Flaw detectors are fixedly mounted at the bottom of the first fixing plate and the middle position of the top of the second fixing plate, and there is a gap between the two flaw detectors to allow the steel strip to pass through. The bottom of the second fixing plate is provided with two through-holes, which are symmetrically arranged front and back. A screw passes through each of the two holes, and a nut is screwed to the top of the screw. A coaxial limit wheel is rotatably mounted on the top of the screw.

[0007] By adopting the above technical solution, the screw enters from the bottom of the waist-shaped hole and exits from the top of the waist-shaped hole. The screw can be tightened into a fixed position in the waist-shaped hole by the nut. The right side position of the steel strip is restricted by the limit wheel at the top. The left and right positions of the screw in the waist-shaped hole are adjustable.

[0008] In a further embodiment, rollers are symmetrically arranged at the center of the mounting plate, and the rollers are used to cooperate with the limiting rollers to limit the position of the steel strip.

[0009] By adopting the above technical solution, the roller is used to limit the position of the left side of the steel strip, thereby limiting the position of the steel strip.

[0010] In a further embodiment, a rectangular block is provided at the middle position of the bottom right side of the mounting plate, and a receiving groove corresponding to the rectangular block is provided at the bottom left side of the second fixing plate. A round rod is slidably mounted on the front side of the second fixing plate. The left end of the round rod passes through the second fixing plate and is movably connected to the mounting plate. A protrusion is provided at the right end of the round rod, and a groove is provided at the bottom right side of the front end face of the mounting plate.

[0011] By adopting the above technical solution, the left end of the round rod is movably set in the groove. When the round rod moves from left to right in the second fixed plate, the round rod drives the mounting plate to move to the left. Therefore, the gap between the mounting plate and the second fixed plate becomes smaller until the protrusion on the round rod is restricted by the second fixed plate and can no longer move to the right. At this time, the mounting plate and the second fixed plate are in contact. Conversely, when the round rod moves from right to left in the second fixed plate, the round rod drives the mounting plate to move to the left. The gap between the mounting plate and the second fixed plate becomes larger until the protrusion on the round rod is restricted by the second fixed plate and can no longer move to the left. The purpose of this structure is to control the left and right positions of the lower second fixed plate relative to the mounting plate. The rectangular block and the groove cooperate to achieve positioning.

[0012] In a further embodiment, the top of the mounting plate is provided with an integrally formed rightward extension, a bracket is fixedly mounted on the top front side of the extension, and a counting wheel is provided on the bottom front side of the bracket.

[0013] By adopting the above technical solution, the counting wheel is used to record the length of the steel strip by rotating a certain number of times.

[0014] In a further embodiment, the first fixing plate is provided with grip handles at both the front and rear ends.

[0015] In a further embodiment, both the first fixing plate and the second fixing plate are provided with an integrally formed baffle, which is used to surround and protect the periphery of the flaw detector.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. The screw is inserted from the bottom of the oblong hole and exits from the top of the oblong hole. The screw can be tightened to a fixed position in the oblong hole by the nut. The right side of the steel strip is restricted by the limit wheel at the top. The left and right positions of the screw in the oblong hole are adjustable. Attached Figure Description

[0023] Example 1:

[0024] like Figures 1-2 As shown, an elevator steel strip flaw detector includes a mounting plate 1. A first fixing plate 2 is fixedly mounted on the top right side of the mounting plate 1, and a second fixing plate 3 is provided at the bottom right side of the mounting plate 1. There is a gap between the first fixing plate 2 and the second fixing plate 3. Flaw detectors 4 are fixedly mounted at the bottom of the first fixing plate 2 and the middle position of the top of the second fixing plate 3, with a gap between the two flaw detectors 4 to allow the steel strip to pass through. The bottom of the second fixing plate 3 has two through-holes, which are symmetrically arranged front and back. A screw 5 passes through each of the two holes, and a nut is screwed to the top of the screw 5. A coaxial limiting wheel 6 is rotatably mounted on the top of the screw 5. Rollers 7 are symmetrically arranged front and back at the middle position of the mounting plate 1. The rollers 7 are used for... The first fixing plate 2 is equipped with a limiting wheel 6 to restrict the position of the steel belt; a rectangular block 8 is provided at the middle of the bottom right side of the mounting plate 1, and a receiving groove corresponding to the rectangular block 8 is provided at the bottom left side of the second fixing plate 3. A round rod is slidably mounted on the front side of the second fixing plate 3, with the left end of the round rod passing through the second fixing plate and movably connected to the mounting plate 1. A protrusion is provided at the right end of the round rod, and a groove is provided at the bottom right side of the front face of the mounting plate 1; an integrally formed rightward extension 9 is provided at the top of the mounting plate 1, and a bracket is fixedly mounted on the top front side of the extension 9. A counting wheel is provided at the bottom front side of the bracket; a grip handle is provided at both the front and rear ends of the first fixing plate 2; an integrally formed baffle is provided on both the first fixing plate 2 and the second fixing plate 3, and the baffle is used to surround and protect the periphery of the flaw detector 4.

[0025] Specific implementation process: Before using the elevator steel strip flaw detector, adjust the left and right position of the screw rod according to the width of the steel strip through the oblong hole. Insert the screw rod into the bottom and out of the oblong hole, tighten the nut to fix the screw rod in a suitable position within the oblong hole. At this time, the limiting wheel at the top can restrict the position of the right side of the steel strip. At the same time, the rollers symmetrically arranged in the middle of the mounting plate can restrict the position of the left side of the steel strip. The two work together to limit the position of the steel strip. Next, operate the relative position of the second fixing plate and the mounting plate, push the round rod that slides left and right on the front side of the second fixing plate. When the round rod moves from left to right, it drives the mounting plate to move to the left, and the gap between the mounting plate and the second fixing plate decreases until the protrusion on the round rod is restricted by the second fixing plate and can no longer move to the right. At this time, the two plates are in contact. Conversely, when the round rod moves from right to left, the mounting plate and the second fixing plate are in contact. The gap between the two fixed plates increases until the protrusion is restricted and can no longer move to the left. During this process, the rectangular block and the receiving groove cooperate to achieve positioning, thereby ensuring accurate adjustment of the position between the mounting plate and the second fixed plate. After the position is adjusted, the steel strip is passed through the gap between the two flaw detectors, so that the flaw detector can perform a comprehensive inspection of the steel strip. At this time, the counting wheel set on the top bracket on the front side of the top edge of the mounting plate will contact the surface of the steel strip. As the steel strip moves, the counting wheel rotates. By recording the number of rotations, the length of the steel strip is accurately recorded. During the inspection, the handles at the front and rear ends of the first fixed plate make it convenient for the operator to hold the equipment, while the baffles integrally formed on the first and second fixed plates can surround and protect the flaw detector, preventing external factors from damaging the flaw detector and ensuring that the inspection work can be carried out stably and accurately.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0027] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
