Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator equipment testing technology, specifically to a mechanical probe assembly for detecting elevator guide shoe wear. Background Technology
[0002] The elevator guide shoe wear detection mechanical probe assembly is a mechanical structure device used to monitor the wear condition of elevator guide shoes in real time. Through its adaptive installation with the elevator guide shoes and guide rails, it utilizes the rigid contact or linkage of the mechanical structure to directly contact the wear surface of the guide shoes, accurately sensing changes in the amount of wear. Various detection technologies exist, such as contact detection technology and non-contact detection technology. For older residential communities with limited budgets, contact detection technology, which requires only low-cost maintenance, is generally used.
[0003] However, in practical applications, due to the operation of elevators, the mechanical probes of contact detection technology are prone to positional displacement due to elevator vibration and stops. Mechanical probes are usually placed at the outermost edge of the wear observation area, so if the position changes, it will have a great impact on the detection results. However, during maintenance, it is not possible to observe the displacement position relatively intuitively, which delays maintenance time. Therefore, it is necessary to provide a mechanical probe assembly for elevator guide shoe wear detection. Utility Model Content
[0004] The purpose of this utility model is to provide a mechanical probe assembly for detecting elevator guide shoe wear, thereby solving the problems mentioned in the background section. To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0005] This utility model is a mechanical probe assembly for detecting elevator guide shoe wear, comprising:
[0006] The detection mechanical probe body has a guide shoe and rubber pads fixed to three sides of the inner side of the guide shoe by threads at its lower end.
[0007] The prediction component includes a connecting block welded to one end of the main body of the detection mechanical probe, rectangular slots symmetrically opened on both sides of one side of the connecting block, a threaded hole opened in the middle section of the rectangular slot, a detection probe threadedly fixed in the middle section of the connecting block, and an observation ruler threadedly fixed in the rectangular slot.
[0008] Furthermore, the prediction component also includes a screw fixed in a threaded hole and a connecting post sleeved outside the screw. The screw passes through the detection probe and the observation ruler, fixing them in the threaded hole.
[0009] Furthermore, the prediction component also includes a rubber post fitted on the screw and a butterfly spring fitted on the screw, wherein the rubber post is located inside the detection probe and the butterfly spring is located inside the rubber post.
[0010] Furthermore, the outer surface of the rubber pad has a groove, and the measuring probe is located in the groove, with the outer surface not higher than the surface of the rubber pad.
[0011] Furthermore, it also includes a reminder component, which includes a central fixing block fixed to one side of the upper end of the rubber pad, a torsion spring fitted inside the fixing block, and rotating blocks fixed to both ends of the torsion spring.
[0012] Furthermore, the reminder component also includes locking blocks threaded to both ends of the rectangular groove, the locking blocks abutting against the inside of the observation ruler.
[0013] Furthermore, the reminder component also includes a push block fixed to one end of the rotating block.
[0014] This invention has the following advantages: When the detection probe is subjected to vibration, the rubber column fitted on the bolt absorbs the vibration, and at the same time, the disc spring holds the bolt to prevent it from loosening. However, if the vibration is too severe, the bolt will become skewed or loose, and the detection mechanism probe body fixed by the bolt will be displaced. When the detection mechanism becomes loose, it will drive the observation scale fixed inside the detection probe to move together. The observation scale will bulge or dent from the edge, thereby making the observation clearer, reducing delay time, and improving the use effect. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0026] Please see Figure 1-6 As shown, this utility model is a mechanical probe assembly for detecting elevator guide shoe wear, comprising:
[0027] The mechanical probe body 10 is tested, and a guide shoe 11 and rubber pads 12 are fixed to the lower end of the mechanical probe body 10.
[0028] The prediction component includes a connecting block 20 welded to one end of the detection mechanical probe body 10, rectangular grooves 21 symmetrically opened on both sides of one side of the connecting block 20, a threaded hole 22 opened in the middle section of the rectangular groove 21, a detection probe 23 threadedly fixed in the middle section of the connecting block, and an observation ruler 24 threadedly fixed in the rectangular groove 21.
[0029] The main body 10 of the mechanical probe is the basic frame, which includes the basic components for detection. The rubber pads 12 on the three inner sides of the guide shoe 11 serve to buffer and dampen vibration, reduce direct rigid friction between the guide shoe 11 and the guide rail, reduce vibration, and provide an installation reference for the detection probe 23. In the prediction component, the connecting block 20 is welded to the main body, and the rectangular groove 21 and threaded hole 22 are used to install the detection probe 23 and the observation ruler 24, etc. The detection probe 23 measures wear, and the observation ruler 24 visually displays whether the detection probe 23 is tilted due to vibration.
[0030] The prediction component also includes a screw 25 fixed in the threaded hole 22 and a connecting post 26 sleeved outside the screw 25. The screw 25 passes through the detection probe 23 and the observation ruler 24 and fixes them in the threaded hole 22.
[0031] The screw 25 passes through the detection probe 23 and the observation ruler 24 and is fixed in the threaded hole 22 to achieve a rigid connection. The connecting post 26 is sleeved on the outside of the screw 25 for auxiliary fixation to prevent the screw 25 from affecting the detection probe 23 and the observation ruler 24 due to vibration.
[0032] The prediction component also includes a rubber post 27 fitted on the screw 25 and a butterfly spring 28 fitted on the screw 25. The rubber post 27 is located inside the detection probe 23, and the butterfly spring 28 is located inside the rubber post 27.
[0033] The rubber column 27 sets of buffer probes make rigid contact with the connecting block 20 to absorb high-frequency vibrations; the disc spring 28 is sleeved on the screw 25 and located inside the rubber column 27, providing continuous pre-tightening force to prevent the screw 25 from loosening, and can also compensate for the gaps caused by wear.
[0034] The outer surface of the rubber pad 12 has a groove, and the probe is placed in the groove, with the outer surface not higher than the surface of the rubber pad 12.
[0035] The outer surface of the rubber pad 12 is grooved, and the detection probe 23 is placed in the groove with its outer surface not higher than the surface of the rubber pad 12. This avoids direct friction between the probe and the guide rail, which could damage the probe and affect the detection effect. At the same time, it can accurately monitor the wear of the rubber pad 12.
[0036] Working principle: When the detection probe 23 is vibrated, the rubber column 27 fitted on the bolt absorbs the vibration. At the same time, the disc spring 28 holds the bolt to prevent it from loosening. However, if the vibration is too severe, the bolt will become skewed or loose, and the detection mechanism probe body fixed by the bolt will be displaced. When the detection mechanism becomes loose, it will drive the observation ruler 24 fixed inside the detection probe 23 to move together. The observation ruler 24 will bulge or dent from the edge, thus making the observation clearer.
[0037] This solution, through the set predictive components, can quickly and intuitively detect whether the elevator guide shoe 11 is misaligned or tilted, causing the detection mechanical probe to fail to respond, thereby improving maintenance efficiency, enhancing safety performance, and preventing personal injury.
[0038] The predictive component can only observe the angle of skew; if maintenance is not carried out in time, it can still easily lead to danger. Therefore, a reminder component is installed to solve the above problem:
[0039] Specifically, it also includes a reminder component, which includes a central fixing block 30 fixed to one side of the upper end of the rubber pad 12, a torsion spring 31 embedded in the fixing block, and a rotating block 32 fixed to both ends of the torsion spring 31.
[0040] The central fixing block 30 is used to fix and protect the torsion spring 31. The torsion spring 31 provides elastic force to reset the rotating block 32.
[0041] The reminder component also includes locking blocks 33 that are threaded to both ends of the rectangular groove 21, and the locking blocks 33 abut against the inside of the observation scale 24;
[0042] The locking block 33 is threaded to both ends of the rectangular groove 21 and abuts against the inside of the observation scale 24, limiting the lateral displacement of the observation scale 24 and ensuring accurate scale display.
[0043] The reminder component also includes a push block 34 fixed to one end of the rotating block 32;
[0044] The push block 34 is fixed to one end of the rotating block 32. When the guide shoe 11 wears down to the threshold, it is pushed by the observation ruler 24, which drives the rotating block 32 to trigger an alert.
[0045] Working principle: When the observation ruler 24 begins to misalign, it will push the push block 34 upward, causing the push block 34 to rotate. The push block 34 will then cause the rotating block 32 to rotate in the middle of the locking block 33. The rotating block 32 will cause the torsion spring 31 to rotate, and the torsion spring 31 will exert a reverse force on the observation ruler 24, pushing the observation ruler 24 in the opposite direction, further limiting the tilt of the observation ruler 24 and preventing it from tilting excessively. When the observation ruler 24 tilts more than halfway, it will push the rotating block 32 to the limit range. An alarm button or electromagnetic induction device can be placed on it for further early warning.
[0046] This solution controls the tilt of the detection probe 23 by setting an alarm component. It can control the tilt of the detection probe 23 for a period of time and also control it to sound an alarm when it is about to fail, thus further ensuring its safety.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
