TECHNICAL FIELD
[0001] The present application relates to the technical field of flaw detection equipment, and in particular to an industrial elevator guide rail ultraviolet flaw detection device. BACKGROUND
[0002] In the field of industrial elevator operation and maintenance, the guide rail, as a core bearing component to ensure the safe operation of the elevator, the accurate detection of its surface and internal defects (such as cracks, wear, corrosion, etc.) is directly related to the safety and service life of the equipment. Currently, the industry generally uses ultraviolet flaw detection technology to non-destructively detect elevator guide rails, relying on ultraviolet flaw detectors to capture the fluorescence response of the defect area to achieve visual identification of small damage. Due to its high detection accuracy and fast response speed, this technology has become the mainstream method for guide rail flaw detection.
[0003] However, the existing industrial elevator guide rail ultraviolet flaw detection equipment still has some deficiencies: most existing ultraviolet flaw detection equipment can only be adjusted at a few fixed length intervals. For low areas in the low-level elevator shaft (such as the bottom of the guide rail and the car connection part, and the guide rail section near the power distribution cabinet), the equipment is still too long due to the minimum extension length, and the ultraviolet flaw detector cannot be lowered to the height close to the detection surface, resulting in that the collected image contains a large amount of redundant background information such as shaft walls and cables, which interferes with the accurate identification of the defect area, and even misses small cracks at the root of the guide rail due to angle deviation. In the face of high-rise elevator shafts or high-position guide rail sections (such as the top of the guide rail and the machine room connection area), the maximum extension length of the equipment is insufficient, making it difficult to raise the ultraviolet flaw detector to the appropriate detection height, resulting in a monitoring blind area at the top of the guide rail, corners and other key areas, and the inability to obtain complete flaw detection data for the entire guide rail, which poses a safety hazard.

[0020] Referring to Figure 4 and Figure 5The locking device 4 comprises a clamping groove 41 opened at one side end of the extension rod 1, the top end and the two sides of the clamping groove 41 are bevels, the bottom end of the clamping groove 41 is a plane, the clamping groove 41 is provided with multiple groups and is evenly opened at the two sides of the extension rod 1, the bottom end of the shell 1 is rotatably provided with a gear 1, and one end of the extension rod 1 penetrates through the shell 1 and the gear 1 and is rotatably connected with the gear 1, the bottom end of the gear 1 is provided with a cavity 43, the cavity 43 is provided with a limiting piece 44, the limiting piece 44 is provided with two groups and is symmetrically distributed at the two sides of the extension rod 1, the limiting piece 44 comprises a spring 3 443 fixedly connected with the inner wall of the cavity 43, one end of the spring 3 443 is fixedly connected with a fixed plate 441, the spring 3 443 is provided with two groups and is symmetrically distributed at the side end of the fixed plate 441, one end of the fixed plate 441 is fixedly connected with a clamping block 442, the top end and the two sides of the tip of the clamping block 442 are bevels, the bottom end of the clamping block 442 is a plane, and the clamping block 442 is matched with the clamping groove 41, when it is necessary to adjust the length of the equipment, the gear 1 is rotated by ninety degrees, the limiting piece 44 in the cavity 43 is rotated to one side where the clamping groove 41 is located, then the extension rod 1 is pulled, with the movement of the extension rod 1, the top end bevel of the clamping block 442 abuts against the top end of the clamping groove 41, because the top end of the clamping groove 41 is a bevel, in the process of moving downward of the extension rod 1, the clamping block 442 is forced to move outwardly due to the outward force of the bevel, the spring 3 443 is compressed, so that the clamping block 442 is separated from the current clamping groove 41, when the extension rod 1 moves to the position of the next clamping groove 41, the spring 3 443 is not forced any more and restores to the original length, the clamping block 442 is pushed into the clamping groove 41, at this time, the clamping block 442 is in contact with the bottom plane of the clamping groove 41, under the action of the plane, the extension rod 1 and the extension rod 2 26 are prevented from being reset under the elastic restoring force of the spring 1 24 and the spring 2 27, so that the change of the overall length of the equipment is realized, when resetting, the gear 1 is reversely rotated by ninety degrees, in the process of rotating, the side end bevel of the clamping block 442 abuts against the side end bevel of the clamping groove 41, which makes the spring 3 443 be compressed and the clamping block 442 be separated from the current clamping groove 41, at this time, the clamping block 442 and the clamping groove 41 are not limited, the extension rod 1 and the extension rod 2 26 are reset under the action of the spring 1 24 and the spring 2 27 and are retracted into the shell 1.
[0021] By the cooperation of the clamping groove 41 and the limiting piece 44, the length of the equipment can be effectively fixed, after the length of the equipment is adjusted to the appropriate position, the contact between the clamping block 442 and the bottom plane of the clamping groove 41 can bear the elastic force of the spring 1 24 and the spring 2 27, so that the extension rod 1 and the extension rod 2 26 cannot be moved at will, this stable fixing function is very important for flaw detection work, because it can avoid the change of the length of the equipment in the process of collecting images and affect the image quality.
[0022] Refer to Figure 6 and Figure 7The locking device 4 further comprises an inner rod 48 penetrating through the shell 1, the spring 27, the second push plate 25 and the extension rod 26 in sequence and being in sliding insertion with the shell 1, the second push plate 25 and the extension rod 26, the inner rod 48 is L-shaped, sliding connection with mounting plates 410 is formed on the outer side of the inner rod 48, the mounting plates 410 are provided in two groups, a gear 42 is rotatably connected between the two groups of mounting plates 410, a rotating piece 412 is in sliding insertion on the gear 42, the gear 42 is in meshing connection with the gear 42, the rotating piece 412 comprises an insertion column 4121 penetrating through the mounting plates 410 and the gear 42 and being in sliding insertion with the gear 42, a stop block 4123 is fixedly connected to the top end of the insertion column 4121, the stop block 4123 is fixedly connected with the shell 1, a stop block 4124 is fixedly connected to the bottom end of the insertion column 4121, a guide strip 4122 is fixedly connected to the side end of the insertion column 4121, the guide strip 4122 is spiral-shaped, the guide strip 4122 is provided in four groups and is uniformly distributed on the side end of the insertion column 4121, the guide strip 4122 is in insertion with the gear 42, under the guidance of the guide strip 4122, the gear 42 is rotated by ninety degrees, in use, the inner rod 48 is first pulled downward, the inner rod 48 is in abutment with the limiting block 46 below the insertion rod 47, because the inner rod 48 moves downward, the mounting plates 410 slidingly connected to the outer side of the inner rod 48 are synchronously moved, the movement of the mounting plates 410 makes the insertion column 4121 in the gear 42 in the mounting plates 410 in abutment with the stop block 4124, under the abutment force, the insertion column 4121 moves upward, when the insertion column 4121 moves upward, the spiral-shaped guide strip 4122 at the side end of the insertion column 4121 interacts with the gear 42, because the guide strip 4122 is spiral-shaped, under the guidance of the guide strip 4122, the gear 42 is rotated by ninety degrees, because the gear 42 is in meshing connection with the gear 42, the rotation of the gear 42 drives the gear 42 to synchronously rotate by ninety degrees, after the gear 42 is rotated by ninety degrees, the limiting piece 44 in the cavity 43 of the gear 42 is rotated to one side where the clamping groove 41 is located, after the image acquisition is completed, the inner rod 48 is pushed upward, so that the inner rod 48 is in abutment with the limiting block 46 above the insertion rod 47, during the upward movement of the inner rod 48, the mounting plates 410 are synchronously moved upward, in this way, the guide strip 4122 is out of the gear 42, so that the gear 42 is reversely rotated by ninety degrees, during the rotation, the side end inclined surface of the clamping block 442 of the limiting piece 44 in the gear 42 is in abutment with the side end inclined surface of the clamping groove 41, so that the spring 443 is compressed under force, the clamping block 442 is separated from the clamping groove 41.
[0023] Adopting the above scheme: through the transmission cooperation between the inner rod 48, the gear two 411 and the gear one 42, the length adjustment of the equipment can be accurately controlled, and each time the gear two 411 rotates by ninety degrees, the gear one 42 can be accurately driven to rotate by the same angle, thereby regularly changing the position of the limiting piece 44, so that the extension rod one 23 and the extension rod two 26 move in a predetermined manner, the length of the equipment is accurately changed, which is crucial for adjusting the ultraviolet flaw detector 3 to a suitable height to collect the appearance image of the elevator guide rail, and the structure design facilitates the operation and reset of the equipment, and the user can realize the extension and retraction of the equipment by means of a series of transmission components through simply pulling or pushing the inner rod 48.
[0024] With reference to Figures 4 to 6 The extension rod one 23 is fixedly connected with a connecting rod 45 at the end face, the connecting rod 45 is J-shaped, the connecting rod 45 is fixedly connected with a plug rod 47 at the end face, the plug rod 47 is fixedly connected with a limiting block 46 at the end face, the limiting block 46 is C-shaped, the inner diameter of the C-shaped limiting block 46 is the same as the cross-sectional diameter of the inner rod 48, the inner rod 48 is provided with a plug slot 49 at the end face, the plug rod 47 is slidably inserted into the plug slot 49, when the inner rod 48 is pulled downward, the inner rod 48 abuts against the limiting block 46 below the plug rod 47, the downward movement of the inner rod 48 transmits force through the contact with the limiting block 46, because the plug rod 47 is fixedly connected with the limiting block 46 at the end face, and the plug rod 47 is connected with the extension rod one 23 through the connecting rod 45 at the end face, so as the inner rod 48 continuously moves downward, the limiting block 46 below the plug rod 47 is driven to move downward, thereby driving the plug rod 47 to move.
[0025] Adopting the above scheme: through the combination design of the connecting rod 45, the limiting block 46, the plug rod 47 and the plug slot 49, the movement of the inner rod 48 can be effectively converted into the movement of the extension rod one 23, through the abutment of the limiting block 46 and the inner rod 48, and the sliding insertion of the plug rod 47 and the plug slot 49, the pulling force or the pushing force of the inner rod 48 can be accurately transmitted to the extension rod one 23, thereby driving the adjusting device 2 to work, realizing the length adjustment of the equipment, and the force transmission mode ensures the accuracy and reliability of the equipment in the operation process, so that the user can accurately control the length of the equipment through the operation of the inner rod 48.
[0026] With reference to Figure 8The protection piece 5 includes a protection plate 51 hinged to the side end of the extension rod two 26. The protection plate 51 is in the shape of a C-shaped petal. Four sets of protection plates 51 are evenly distributed on the side end of the extension rod two 26. When the four sets of protection plates 51 are closed, the ultraviolet flaw detector 3 is wrapped and protected. The protection piece 5 further includes a fixing ring 52 clamped to the outer side of the protection plate 51. The fixing ring 52 is clamped to the protection plate 51 in the closed state. The inner diameter of the fixing ring 52 is the same as the maximum outer diameter of the protection plate 51. An activation cylinder 53 is fixedly connected to the fixing ring 52. The activation cylinder 53 is provided with two sets of symmetrically distributed upper and lower ends of the fixing ring 52. When the length of the device is adjusted and the ultraviolet flaw detector 3 is lifted to an appropriate height, the activation cylinder 53 above the fixing ring 52 is abutted against a solid object. Under the abutment force, the activation cylinder 53 moves downward. Since the activation cylinder 53 is fixed to the fixing ring 52, the downward movement of the activation cylinder 53 releases the abutment of the fixing ring 52 and the protection plate 51. Subsequently, the fixing ring 52 and the activation cylinder 53 fall downward under the action of gravity until the activation cylinder 53 below the fixing ring 52 is in contact with the top end of the shell 1. At this time, the closed protection plate 51 loses the limitation of the fixing ring 52 and opens under the action of gravity, thereby exposing the ultraviolet flaw detector 3 for collecting the appearance image of the elevator guide rail and performing flaw detection work. After completion, the inner rod 48 is pushed upward, and the device starts to reset. During the resetting process, the extension rod one 23 and the extension rod two 26 are retracted into the shell 1 under the action of the spring one 24 and the spring two 27. At this time, the bottom end of the protection plate 51 in the open and closed state is abutted against the activation cylinder 53 above the fixing ring 52. With the continuation of the resetting process, the protection plate 51 gradually recovers to the closed state under the abutment action of the activation cylinder 53 until the fixing ring 52 moves to the maximum diameter of the protection plate 51 again. The fixing ring 52 fixes the protection plate 51, thereby wrapping and protecting the ultraviolet flaw detector 3 again.
[0027] By adopting the above scheme: through the protection piece 5, the four sets of C-shaped petal-shaped protection plates 51 can be closed during non-use or transportation of the device, thereby wrapping and protecting the ultraviolet flaw detector 3, preventing the ultraviolet flaw detector 3 from being physically damaged by external collision and scratching, and prolonging the service life of the ultraviolet flaw detector 3. When opening, the activation cylinder 53 only needs to be abutted against a solid object. The opening of the protection plate 51 is realized by using a simple mechanical structure and gravity, without the need for complex operation steps. When closing, the protection plate 51 recovers to the closed state and is re-fixed by means of the natural contact between the components during the resetting process of the device, which is easy for the user to operate.

At this time, the clamping block 442 and the clamping groove 41 are no longer restricted, and the extension rod 1 and the extension rod 2 are reset under the action of the spring 24 and the spring 27, and are retracted into the shell 1. During the resetting process, the bottom end of the protection plate 51 in the open and closed state is in abutment with the activation cylinder 53 above the fixed ring 52, so that the protection plate 51 returns to the closed state, and the fixed ring 52 is fixed to the protection plate 51 until the fixed ring 52 moves to the maximum diameter of the protection plate 51 again, so that the fixed ring 52 fixes the protection plate 51. By adjusting the synchronization box 21 in the adjusting device 2 and through the linkage mechanism of the push plate and the ball 28, the reverse motion control of the extension rod 1 and the extension rod 2 is realized. When the length of the device needs to be changed, it is simple and direct to pull the extension rod 1, so that the overall length of the device can be accurately changed through a series of transmissions. This design can adapt to the diversified needs of the height of the ultraviolet flaw detector 3 in different flaw detection scenes, facilitate the adjustment of the ultraviolet flaw detector 3 to the appropriate height, effectively improve the efficiency and adaptability of the flaw detection work, reduce the time and effort consumed due to the inconvenience of adjusting the length of the device, and provide strong support for the elevator rail flaw detection work. The convenience and accuracy of the length adjustment of the device are greatly improved. Through the inclined surface guidance and plane support of the clamping groove 41 and the limiting piece 44 in the locking device 4, it is ensured that the device can be firmly locked after being adjusted to the required length. Multiple clamping grooves 41 provide rich length selection and accurate positioning. During the operation of the device, the length change of the device caused by accidental collision, vibration or spring elasticity change is effectively prevented, the stability and accuracy of the flaw detection work are greatly improved, the reliability of the flaw detection data is ensured, and the risk of image blur or data deviation caused by device shaking is reduced. A reliable and stable guarantee is provided for the fixation of the length of the device. The C-shaped flap protection plate 51 in the protection piece 5 tightly wraps the ultraviolet flaw detector 3 when closed, forming a protective barrier that can effectively block collisions and scratches during daily handling, greatly extending the service life of the ultraviolet flaw detector 3 and reducing maintenance costs. When opened, it can be realized through simple interaction between the activation cylinder 53 and external objects. When closed, it is automatically completed during the resetting process of the device. This design is not only convenient and fast, but also avoids the situation that the ultraviolet flaw detector 3 is damaged due to human negligence forgetting to close the protection. While improving the ease of use of the device, the protection effect of the ultraviolet flaw detector 3 is further improved, ensuring that the ultraviolet flaw detector 3 can maintain good working condition under various working conditions, and giving the ultraviolet flaw detector 3 comprehensive and intelligent protection.
