Technical Field

[0001] The present application relates to the technical field of industrial detection equipment, and in particular to an automatic flaw detection device for elevator wire ropes. Background Art

[0002] Elevators are vertical transportation devices, and people's lives depend entirely on their safe operation. The elevator wire rope is a key component, bearing the full weight of the car and counterweight. During operation, it is frequently subjected to complex stresses such as tension, bending, and torsion. If a serious problem such as a wire rope breakage occurs, the car could fall, resulting in catastrophic consequences. Flaw detection can detect minor defects such as broken wires, wear, and corrosion in the wire rope and on its surface, allowing for timely repair or replacement, effectively preventing elevator accidents.

[0003] In the existing technology, flaw detection of wire ropes is usually carried out using ultrasonic flaw detectors or electromagnetic flaw detectors. Regardless of the flaw detection method, the equipment needs to be manually held and moved along the wire rope. However, the space in the elevator shaft is small, making it inconvenient for construction workers to enter, and it is very easy to put their lives in danger during operation.

[0004] Therefore, the inventor is necessary to design a new elevator wire rope automatic flaw detection device to overcome the problems mentioned above. Summary of the Invention

[0021] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0022] It should be noted that the terms "first", "second", etc. in the specification of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order.

[0025] Additionally, the term "plurality" shall mean two or more.

[0026] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] like Figures 1 to 2 As shown, an automatic flaw detection device for an elevator wire rope 10 includes a mounting plate, a first clamping member 2, a second clamping member 3 and a flaw detection assembly, wherein the first clamping member 2 is fixedly arranged on the mounting plate, the second clamping member 3 is slidably arranged on the mounting plate, a driving assembly is fixedly arranged between the second clamping member 3 and the mounting plate, the flaw detection assembly is fixedly arranged on the mounting plate and slides on the external wire rope 10, and the clamping parts of the first clamping member 2 and the second clamping member 3 are both clamped on the wire rope 10.

[0028] Specifically, when in use, the first clamping piece 2 and the second clamping piece 3 are clamped on the elevator wire rope 10, and then the flaw detection assembly is put on the wire rope 10. When the inspection starts, the first clamping piece 2 is loosened, and then the driving assembly is started to drive the mounting plate to move upward, thereby driving the first clamping piece 2 and the flaw detection assembly to move upward. When the flaw detection assembly moves to the top of this stroke, the first clamping piece 2 re-clamps the wire rope 10, and then the second clamping piece 3 is loosened. At this time, the second clamping piece 3 is the movable end, and the second clamping piece 3 can be driven to move upward by the driving assembly. When it moves to the farthest distance, the second clamping piece 3 is re-clamped. At this time, the above operation is repeated to realize the automatic movement of the flaw detection assembly on the elevator wire rope 10. This embodiment provides a first clamping member 2 and a second clamping member 3 to intermittently clamp the wire rope 10, and provides a driving component between the two to adjust the distance between the two, thereby driving the automatic movement of the flaw detection component on the wire rope 10, eliminating the operation of manually moving the flaw detection component, greatly reducing the construction risk for personnel, and being suitable for narrow spaces.

[0029] The mounting plate comprises an L-shaped plate 1, with the first clamping member 2 fixedly mounted on the horizontal plate of the L-shaped plate 1, a slide rail 4 fixedly mounted on the vertical plate of the L-shaped plate 1, and the second clamping member 3 slidably connected to the slide rail 4. The drive assembly is a cylinder 5, the bottom of which is fixedly mounted on the horizontal plate of the L-shaped plate 1, and the telescopic portion of the cylinder 5 is fixedly connected to the second clamping member 3. Specifically, if the second clamping member 3 is directly mounted on the end of the cylinder 5 without the slide rail 4 to guide its movement, the telescopic end of the cylinder 5 may suffer from excessive bending stress, resulting in poor telescopic movement and even damage to the cylinder 5.

[0030] The first clamping member 2 and the second clamping member 3 are both electric clamps. Specifically, electric clamps have mature technology, stable operation, and relatively low cost, and are suitable for application in this device.

[0031] The flaw detection component is an electromagnetic flaw detector 6. Specifically, an ultrasonic flaw detector needs to be coated with coupling agent, which easily causes the friction force of the clamping position of the first clamping member 2 to decrease, thereby causing the device to fall.

[0032] The top of the mounting plate is also fixedly connected with a safety rope 7. Specifically, in order to avoid the device from directly falling when it breaks down, the safety rope 7 can be used to prevent it from falling and breaking.

[0033] The flaw detection assembly is detachably connected to the mounting plate via a connecting seat 8. Specifically, the flaw detection assembly can be of different models to adapt to steel wire ropes 10 of different specifications, and the detachable connection here is convenient for replacement.

[0034] The flaw detection assembly is located between the first clamping member 2 and the second clamping member 3. Specifically, the flaw detection assembly is located in the middle, which can effectively reduce the top-heavy situation of the device and make the movement more stable.

[0035] The mounting plate is also fixedly provided with a power supply module 9. Specifically, the power supply module 9 is used to supply power to the first clamping member 2 and the second clamping member 3.

[0036] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
