Description

Technical Field

[0001] This invention belongs to the field of measuring equipment technology, and in particular relates to a chain link measuring device for the production of elevator balance compensation chains with steel balls. Background Technology

[0002] The elevator balance compensation chain is a core component connecting the car and the counterweight. Its performance directly determines the stability and safety of elevator operation, and it must meet stringent requirements such as high load capacity, low operating noise, appropriate weight per unit length, and flexible bending. Among them, the elevator balance compensation chain with steel balls has a special structure in which steel balls are embedded inside the chain links. By replacing the sliding friction between the chain links with the rolling friction of the steel balls, it can significantly reduce operating noise and improve vibration reduction effect, and has become the mainstream choice for medium and high-speed elevators. The performance of this type of compensation chain depends not only on the accuracy of the conventional dimensions of the chain links (internal length, width, and thickness), but also entirely on the fitting accuracy between the steel balls and the working surface of the inner wall of the chain links. This is its core feature that distinguishes it from ordinary compensation chains.

[0003] During the production process, the chain link size inspection must strictly follow standard specifications. The tolerances for internal length, width, and thickness must all be controlled within the allowable error range. Specifically, the internal length determines the consistency of the pitch after the chain links are connected: if it is too long, it will cause the compensation chain to become loose when it expands and contracts, increasing the risk of rubbing against the hoistway components; if it is too short, it will cause the pitch to be too tight, causing running jams, abnormal noises, and accelerating the wear of the pins and chain link holes. The internal width needs to be precisely matched with the diameter of the steel ball. If it is too large, it will cause the steel ball to move around, generating high-frequency noise, and will not be able to effectively distribute the load, resulting in localized stress concentration; if it is too small, it will jam the steel ball, causing it to lose its rolling vibration damping function and directly transmit the vibration to the car. The thickness parameter is also the key to balancing strength and economy: if it is too thin or uneven in some areas, it will form structural weak points, which are prone to bending, denting, or even breaking under the full load tension and self-weight of the car; if it is too thick, it will increase the weight per unit length, which will not only increase the energy consumption of the elevator drive, but also accelerate the aging of the wire rope.

[0004] Current testing technologies have significant limitations. When using a step-by-step measurement mode, the positioning errors from each clamping operation accumulate. More importantly, the uneven pressure applied by the external fixture can easily cause plastic deformation in thin-walled chain links, directly resulting in distorted measurement data. This traditional method cannot meet the stringent dimensional accuracy requirements of standards, nor can it address the efficiency demands of mass production. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a link measuring device for the production of elevator balance compensation chains with steel balls.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a chain link measuring device for the production of an elevator balance compensation chain with steel balls, comprising a detection base and a PLC controller, wherein a material conveyor belt is fixedly mounted on the upper end of the detection base, and two parallel good product material conveyor belts and defective product material conveyor belts are also fixedly mounted on the upper end of the detection base, further comprising:

[0013] Multiple push-pull rods are fixedly connected to opposite sides of the two push-pull plates. The ends of the multiple push-pull rods away from the push-pull plates extend through the detection shell. One end of the multiple push-pull rods on one side is fixedly connected to the same first U-shaped support plate. The first U-shaped support plate is rotatably connected to the same first support rod on the opposite side. A connecting seat is fixedly sleeved on the wall of the first support rod. One side of the connecting seat is fixedly connected to one of the internal support clamping force compensation mechanisms. A torsion return spring sleeved outside the first support rod is fixedly connected to the connecting seat and the opposite side of the first U-shaped support plate. An encoder is fixedly connected to the lower end of the first U-shaped support plate. The lower end of the first support rod is fixedly connected to the input end of the encoder.

[0014] On the other side, one end of the multiple push-pull rods is fixedly connected to the same second U-shaped support plate. The inner side of the second U-shaped support plate is fixedly connected to a second support rod. The side of the second U-shaped support plate away from the push-pull rods is fixedly connected to another set of inner support clamping force compensation mechanisms.

[0015] In the aforementioned chain link measuring device for producing an elevator balance compensation chain with steel balls, the inner support clamping force compensation mechanism includes an inner support shell. An inner support plate is provided on one side of the inner support shell. Multiple push rods are fixedly connected to the side of the inner support plate near the inner support shell. The ends of the multiple push rods away from the inner support plate penetrate the interior of the inner support shell and are fixedly connected to the same force plate. Multiple push springs sleeved on the outside of the push rods are fixedly connected to the opposite side of the force plate and the inner support shell. A thrust permanent magnet plate is fixedly connected to the side of the force plate away from the push rods. A thrust electromagnetic plate is fixedly connected to the inner wall of the inner support shell and is arranged opposite to the thrust permanent magnet plate.

[0016] In the above-mentioned chain link measuring device for producing an elevator balance compensation chain with steel balls, the thickness detection mechanism includes two L-shaped extension plates respectively fixedly connected to the upper ends of the first support rod and the second support rod.

[0020] Compared with existing technologies, the advantages of this invention are as follows:

[0021] 1. With the built-in internal support clamping detection mechanism, thickness detection mechanism, and material conveyor belt, it can quickly detect chain links of different sizes, realize the simultaneous detection of chain link length, width and thickness, effectively improve detection efficiency, and eliminate the need for frequent disassembly and assembly of fixtures, avoiding the problem of the cumulative positioning error of chain links affecting the accuracy of detection results. It can also simultaneously and quickly detect the parallelism of the two sides of the chain link, further improving detection efficiency.

[0022] 2. Through the internal support clamping force compensation mechanism, the magnitude of the internal support clamping force on the chain link can be automatically adjusted based on the size of the chain link. The larger the size, the greater the internal support clamping force, which avoids the problem of slippage between the clamping force and the chain link caused by the clamping force being too low, thus affecting the detection and transfer of the chain link. It also avoids the problem of the internal support clamping force being too large, which may damage the chain link.

[0035] The internal support clamping detection mechanism 3 is fixedly connected to the moving end of the rotary lifting transfer mechanism 2. The internal support clamping detection mechanism 3 includes a detection shell 31 fixedly connected to the lower end of multiple connecting rods 25. Length laser rangefinders 32 are fixedly connected to both the front and rear opposite sides of the detection shell 31. A dual-axis motor 33 is fixedly installed on the top of the inner wall of the detection shell 31. Rotating screws 34 are fixedly connected to both output ends of the dual-axis motor 33.

A limit slider is fixedly connected to the upper end of the push-pull plate 35. A limit groove matching the limit slider is opened on the top of the inner wall of the detection shell 31.

[0036] Multiple push-pull rods 37 are fixedly connected to the opposite sides of the two push-pull plates 35. The ends of the multiple push-pull rods 37 away from the push-pull plates 35 extend through the outside of the detection shell 31. One end of the multiple push-pull rods 37 on one side is fixedly connected to the same first U-shaped support plate 38. The first U-shaped support plate 38 is rotatably connected to the same first support rod 39 on the opposite side. The rod wall of the first support rod 39 is fixedly sleeved with a connecting seat 310. The end of the first U-shaped support plate 38 and the side wall of the connecting seat 310 are both designed with an arc-shaped structure. One side of the connecting seat 310 is fixedly connected to one of the sets of internal support clamping force compensation mechanisms 4. The connecting seat 310 and the opposite side of the first U-shaped support plate 38 are fixedly connected to a torsion return spring 311 sleeved outside the first support rod 39. The lower end of the first U-shaped support plate 38 is fixedly connected to an encoder 312. The lower end of the first support rod 39 is fixedly connected to the input end of the encoder 312.

[0037] On the other side, one end of multiple push-pull rods 37 is fixedly connected to the same second U-shaped support plate 313. The inner side of the second U-shaped support plate 313 is fixedly connected to a second support rod 314. The side of the second U-shaped support plate 313 away from the push-pull rods 37 is fixedly connected to another set of inner support clamping force compensation mechanisms 4.

[0038] Two sets of internal support clamping force compensation mechanisms 4 are fixedly installed at the two output ends of the internal support clamping detection mechanism 3. The PLC controller is configured such that the link size determined by the internal support clamping detection mechanism 3 is positively correlated with the compensation strength of the internal support clamping force compensation mechanism 4. The internal support clamping force compensation mechanism 4 includes an internal support shell 41, an internal support plate 42 is provided on one side of the internal support shell 41, and multiple extrusion rods 43 are fixedly connected to the side of the internal support plate 42 near the internal support shell 41. The multiple extrusion rods 43 are located away from the internal support plate 42. One end of the inner support shell 41 is inserted through the interior and is fixedly connected to the same force plate 44. Multiple push springs 45 sleeved on the outside of the push rod 43 are fixedly connected to the opposite side of the force plate 44 and the inner support shell 41. A thrust permanent magnet plate 46 is fixedly connected to the side of the force plate 44 away from the push rod 43. A thrust electromagnetic plate 47 is fixedly connected to the inner wall of the inner support shell 41 and is arranged opposite to the thrust permanent magnet plate 46. The surface of the inner support plate 42 is covered with a layer of anti-slip rubber pad, and the surface of the anti-slip rubber pad is provided with anti-slip texture.

[0039] Thickness detection mechanism 5 is fixedly installed on the upper end of inner support clamping detection mechanism 3. Thickness detection mechanism 5 includes two L-shaped extension plates 51 that are respectively fixedly connected to the upper ends of the first support rod 39 and the second support rod 314. An electric slide rail 52 is fixedly connected to the lower side wall of the vertical part of the L-shaped extension plate 51. A thickness laser rangefinder 53 is fixedly connected to the moving end of the slider inside the electric slide rail 52.

[0040] The operating principle of the present invention is described as follows: The chain link to be tested is placed on the material conveyor belt 6, and the material conveyor belt 6 moves the chain link to the testing station. When the chain link moves to the testing station, the PLC controller controls the material conveyor belt 6 to stop moving. The PLC controller then controls the electric push rod 22 to drive the lifting plate 24 to move down. The lifting plate 24, together with the connecting rod 25, drives the inner support clamping mechanism to move down synchronously, so that the inner support clamping testing mechanism 3 moves to the inside of the chain link, and the thickness testing mechanism 5 is located on the outside of the chain link.

[0041] The PLC controller then controls the action of the inner support clamping detection mechanism 3. The dual-axis motor 33 drives the two rotating screws 34 to rotate synchronously. Through the threaded connection between the rotating screws 34 and the push-pull plates 35, the two push-pull plates 35 move in opposite directions. Then, through multiple push-pull rods 37, the two sets of inner support clamping force compensation mechanisms 4 move in opposite directions until the two sets of inner support clamping force compensation mechanisms 4 are in contact with the inner side wall of the chain link. Since the output end of the dual-axis motor 33 is equipped with a torque sensor, when the torque signal fed back by the torque sensor reaches the threshold, it indicates that the two sets of inner support clamping force compensation mechanisms 4 have been in contact with the chain link. At this time, the PLC controller controls the dual-axis motor 33 to stop continuing to operate.

[0042] First, when the parallelism difference between the two sides of the chain link that are in contact with the inner support clamping force compensation mechanism 4 exceeds the threshold, since the second U-shaped support plate 313 is fixedly connected to the inner support clamping force compensation mechanism 4, while the first U-shaped support plate 38 is connected to the inner support clamping force compensation mechanism 4 through the relative rotation of the first support rod 39 and the connecting seat 310, the connecting seat 310 will cause the first support rod 39 and the first U-shaped support plate 38 to deflect relative to each other as the inner support clamping force compensation mechanism 4 moves. The encoder 312 detects the deflection angle of the first support rod 39, thereby confirming whether the two opposite sides of the chain link are not parallel. When the detection feedback indicates non-parallelism, the encoder 312 directly feeds back a signal to the PLC controller. The PLC controller directly determines that the current chain link quality is unqualified, and there is no need to continue subsequent inspection work, because the elevator is level. The internal structure of the chain links of the balance compensation chain is mostly rectangular cavity (used to embed steel balls to achieve vibration reduction and load distribution). The parallelism of the two sides inside directly determines the uniformity of contact between the steel balls and the sidewalls. Even if the internal width (single dimension) of the chain link is qualified, if the parallelism deviation is too large, it will still cause hidden problems in the assembly of the steel balls. If the parallelism error of the two side walls exceeds the tolerance (such as a tilt of 0.05mm on one side), it will cause the cavity to form a wedge-shaped gap (one side is wide and the other side is narrow). The narrow side will be in too tight contact with the steel ball, which will cause the steel ball to be obstructed from rotating and lose the rolling vibration reduction function. When the elevator is running, the vibration will be directly transmitted to the car. The wide side will have too large a gap, and the steel ball will move laterally in the chain link and collide with the sidewall to generate high-frequency noise (similar to the abnormal sound of a ball hitting a metal cavity). At the same time, the steel ball cannot distribute the load evenly, and the local sidewall will bear additional pressure, accelerating wear or deformation.

[0043] When the deflection angle fed back by the encoder 312 meets the threshold, the detection of the chain link length, width and thickness continues. The PLC controller controls two length laser rangefinders 32 to detect the distance between the two ends of the detection shell 31 and the inner wall of the chain link in the length direction. Combined with the length of the detection shell 31, the internal length of the chain link is quickly obtained through the calculation and analysis module in the PLC controller. The PLC controller also controls the width laser rangefinder 36 to work. The width laser rangefinder 36 detects the distance between the push-pull plate 35 and the inner wall of the detection shell 31. Since the moving distance of the push-pull plate 35 represents the width of the chain link, the size information of the internal width of the chain link can be quickly obtained.

[0044] Since the thickness detection mechanism 5 is located on the outside of the chain link, the PLC controller controls the electric slide rail 52 and the thickness laser rangefinder 53 to move synchronously, causing the thickness laser rangefinder 53 to move on the outer wall of the chain link. Because the inner support clamping force compensation mechanism 4 abuts against the inner wall of the chain link, and the thickness detection mechanism 5 and the inner support clamping force compensation mechanism 4 are arranged parallel to each other, the thickness laser rangefinder 53 can quickly obtain the thickness information of the chain link and the thickness changes of the chain link sidewall. The dynamic signal analysis module in the PLC controller can perform frequency domain conversion on the real-time data collected by the thickness laser rangefinder 53 to extract the fluctuation frequency characteristics. The rougher the chain link surface, the more obvious the surface unevenness, and the higher the high-frequency fluctuation... The amplitude of the component will increase significantly. The frequency distribution can be used to determine whether it is abnormal. When the surface roughness of the chain link exceeds the threshold, the chain link is also judged to be unqualified. This is because the chain links of the elevator balance compensation chain need to withstand dynamic tension, bending and mutual friction for a long time. Unqualified surface roughness will directly damage its mechanical properties and operational reliability. The chain link needs to be precisely matched with adjacent components (such as pins and chain plates). If the inner / outer surface roughness is poor (such as the presence of burrs or deep dents), jamming is likely to occur during assembly. It is not possible to smoothly insert the pin or fit the chain plate, which will reduce the assembly efficiency of the compensation chain. Moreover, forced assembly will cause uneven fit clearance, resulting in looseness or tightness during operation, which will accelerate local wear.

[0045] After the PLC controller confirms whether the chain link quality is qualified based on the detection feedback of connection length, width, thickness, roughness and parallelism, the PLC controller further controls the action of the inner support clamping force compensation mechanism 4. The PLC controller controls the power supply equipment to supply power to the thrust electromagnetic plate 47. The thrust electromagnetic plate 47 generates the same magnetism as the thrust permanent magnet plate 46 when energized, and then applies a magnetic thrust to the force plate 44. The force plate 44, together with the push rod 43, transmits the magnetic thrust to the inner support plate 42, strengthening the contact pressure between the inner support plate 42 and the chain link. The PLC controller also confirms the magnitude of the power supply current supplied by the power supply equipment to the thrust electromagnetic plate 47 based on the chain link size information fed back by the inner support clamping detection mechanism 3. Specifically, the larger the chain link size and the greater the thickness, the greater the weight of the chain link under the same material, and the better the withstand capacity. The PLC controller controls the power supply equipment to supply a larger current to the thrust electromagnetic plate 47, so that the inner support plate 42 and the chain link generate greater contact pressure, ensuring that the inner support clamping detection mechanism 3 can be stably fixed with the chain link.

[0046] The PLC controller then controls the motor rotation assembly 23 to operate based on whether the detected chain links are qualified. The PLC controller first controls the electric push rod 22 to move the inner support clamping detection mechanism 3 upward, which in turn moves the detected chain links upward synchronously. Then, it controls the motor rotation assembly 23 to drive the electric push rod 22 to rotate, so that the detected chain links rotate directly above the good product material conveyor belt 7 or the defective product material conveyor belt 8, and then place the chain links. It can automatically confirm whether the quality of the chain links is qualified based on the detection of the chain link size, and automatically classify and transport the chain links. It has a sorting function, which facilitates the subsequent processing of the chain links by the staff.
