Technical Field

[0001] The present invention belongs to the technical field of fall arrester testing, and specifically relates to a fall arrester self-locking reliability testing machine. Background Art

[0002] A fall arrester is a protective device that can quickly brake and lock a falling object within a limited distance. It is applicable to the safety protection when preventing the accidentally falling of a lifted workpiece during overhead crane lifting, and can effectively protect the lives of ground operators and the damage of the lifted workpiece. It is applied to high-altitude operation sites such as metallurgy, automobile manufacturing, ships, and bridges; the speed differential type fall arrester has the characteristic of being repeatedly used many times, so the stability of the self-locking function of the speed differential mechanism is particularly important.

[0003] In order to test whether the self-locking function of the speed differential type fall arrester still meets the requirements after being used many times, in the past, the speed differential type fall arrester was suspended on a fixed frame, then a heavy object of a certain weight was suspended at the end of the safety rope and manually held, and then the heavy object was instantaneously released to make it free fall, and the falling distance of the safety rope was measured to see if it was within 1 m. Finally, the heavy object was manually lifted to retract the safety rope into the housing. This method has high labor intensity, low efficiency, poor repeatability, and an unscientific method.

After the measurement is completed, the resetting component lifts the counterweight, and the counterweight is placed well with the cooperation of the placing component, so that the counterweight returns to the height before the test, and the measurement is carried out again, which improves the testing rate and saves a large amount of time for hundreds or thousands of experiments.

[0011] Further, the limiting component includes a telescopic column, one end of the telescopic column is fixedly connected to the inner wall of the frame plate, the other end of the telescopic column is fixedly connected to a fixing frame, arc-shaped rods are symmetrically arranged on the outer wall of the fixing frame, the outer wall of the arc-shaped rod is fixedly connected to the outer wall of the fixing frame, a bent plate is fixedly connected to one side of the outer wall of the fixing frame away from the arc-shaped rod, a limiting plate is fixedly connected to one end of the bent plate away from the fixing frame, an arc-shaped block is fixedly connected to one side of the limiting plate away from the bent plate, and the outer wall of the arc-shaped block is in contact with the bottom of the anti-falling device, so that the arc-shaped rod encloses the rope of the anti-falling device, and the shaking amplitude of the rope is quickly reduced. The frame plate moves downward, so that the rope quickly maintains vertical stability. At this time, the infrared generator moves to a position consistent with the height of the hook at this time, and the measurement is carried out quickly, avoiding excessive shaking and floating of the counterweight, resulting in impact on the inside of the equipment and damage to the equipment. At the same time, it avoids the counterweight falling off during the shaking process and rolling after falling, injuring the staff.

[0012] Further, the homing component includes a driving block, the top of the driving block is fixedly connected to the bottom of the shelf plate, two driving blocks are symmetrically arranged, a bent rod is rotatably connected to the opposite side of the driving block, a receiving plate is rotatably connected to the opposite side of the bent rod, one end of the bent rod away from the driving block is rotatably connected to a connecting rod, the bottom of the connecting rod is rotatably connected to a reel, elastic ropes are symmetrically arranged on the outer wall of the reel, and the outer wall of the elastic ropes is fixedly connected to the outer wall of the reel, so that the elastic ropes control the shaking of the rope, cooperate with the limiting component to make the counterweight quickly stable, and the receiving plate unloads and buffers the counterweight when the counterweight falls off, preventing the counterweight from flying out. After the measurement is completed, the bent rod drives the receiving plate to approach the counterweight, and the counterweight is lifted during the rotation process, and the counterweight is returned to its position in cooperation with the placement component. During this process, the limiting component keeps the hanging ring stationary, and the counterweight can be lifted and reset without manual labor, facilitating multiple tests and saving test time.

[0013] Further, the placement component includes a rotating shaft, the outer wall of the rotating shaft is rotatably connected to the outer wall of the driving block, one end of the rotating shaft away from the driving block is fixedly connected to a placement plate, a telescopic rod is arranged inside the placement plate at the end away from the rotating shaft, the outer wall of the telescopic rod is sleeved with the inner wall of the placement plate, one end of the telescopic rod away from the placement plate is fixedly connected to the outer wall of the driving block, a connecting rope is fixedly connected to the bottom of the placement plate, one end of the connecting rope is fixedly connected to a sliding rod, the bottom of the sliding rod is rotatably connected to the top of the base, and the top of the sliding rod is in contact with the bottom of the placement plate. Cooperate with the homing component to make the bottom of the counterweight contact the top of the placement plate. At this time, the sliding rod supports the bottom of the counterweight, and then the sliding rod rotates into the base again, causing the counterweight to rise and then fall again. Repeat the operation until different weights of counterweights are replaced, making the test process smoother and shortening the test time.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The test process requires repeated operations, which places a large burden on manual labor and has low efficiency. The present invention sets up a test mechanism to quickly reduce the shaking amplitude of the rope, cooperate with the homing component to make the counterweight quickly stable, facilitate the measurement by the measuring mechanism. After the measurement is completed, the homing component lifts the counterweight, and places the counterweight well in cooperation with the placement component, so that the counterweight returns to the height before the test and is measured again. By mechanically lifting and resetting the counterweight repeatedly for testing, it not only saves manpower but also improves the test rate, saving a large amount of time for hundreds or thousands of experiments.

[0016] 2. During the testing process, measurements are usually carried out manually. However, due to the large weight of the counterweight block, serious accidents may occur in case of detachment, and the measurement error of manual measurement is relatively large, which prolongs the measurement time. In the present invention, by setting up a measurement mechanism, after the counterweight block is stabilized, a set of movable seats move downward until the position of the infrared ray coincides with that of the hook, and the data of the two height gauges are recorded at this time. The difference is the falling distance of the arrester. The hollow rod drives the limiting ring to surround the bottom of the arrester, making the elastic rod close to the main body of the arrester, reducing the sway of the arrester, promoting the rapid stability of the main body of the arrester, facilitating rapid reading and measurement, and determining the position of the hook through the infrared generator, which is more accurate than manual measurement.

[0017] 3. In the present invention, by setting up a limiting component, the rope of the arrester is surrounded, so that the sway amplitude of the rope is quickly reduced. The mounting plate moves downward, making the rope quickly maintain vertical stability. At this time, the infrared generator moves to a position consistent with the height of the hook at this time, and measurement is carried out quickly, avoiding excessive sway and floating of the counterweight block, which may cause impact on the inside of the equipment and damage the equipment. At the same time, it avoids the detachment of the counterweight block during the swaying process, resulting in rolling after falling and injuring the staff.

[0018] 4. In the present invention, by setting up a reset component, the elastic rope controls the sway of the rope, and cooperates with the limiting component to quickly stabilize the counterweight block. When the counterweight block falls off, the bearing plate unloads and buffers the counterweight block to avoid the counterweight block flying out. After the measurement is completed, the bent rod drives the bearing plate close to the counterweight block, and lifts the counterweight block during the rotation process, and cooperates with the placement component to reset the configured block. During this process, the limiting component keeps the hanging ring stationary, and the counterweight block can be lifted and reset without manual operation, which is convenient for multiple tests and saves test time.

Specific embodiments

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0029] Example 1, please refer to Figures 1-4 , the present invention provides a technical solution: A description is given of a testing machine for the self-locking reliability performance of an anti-falling device as follows.

[0030] It includes: a base 1, the base 1 is relatively thick to keep the equipment stable when the counterweight 505 shakes. On the top of the base 1, columns 2 are symmetrically arranged, and on one side of the top of the base 1 away from the columns 2, screws 4 are symmetrically arranged;

[0031] This testing machine for the self-locking reliability performance of an anti-falling device further includes:

[0032] A testing mechanism 5, the inner wall of the testing mechanism 5 is slidably connected to the outer wall of the screw 4;

[0033] The top of the column 2 is fixedly connected to a top plate 6. At the bottom of the top plate 6, there is an anti-falling device 7. An inductor for receiving the signal of the infrared generator 302 is installed on the outer wall of the hook of the anti-falling device 7. A measuring mechanism 3 is slidably connected to the outer wall of the column 2.

[0034] During operation, the worker places the counterweight 505 on the test mechanism 5, hangs the fall arrester 7 on the top plate 6, and then the test mechanism 5 drives the counterweight 505 to move upward. During the movement, the counterweight 505 is hooked to the hook of the fall arrester 7. The measuring mechanism 3 is initially in a horizontal position with the sensor on the hook of the fall arrester 7. During the test, the test mechanism 5 releases the counterweight 505 to let it fall naturally, so that the counterweight 505 pulls the fall arrester 7 downward during the sudden fall. When the test mechanism 5 quickly stabilizes the counterweight 505 and makes it stop swaying, the measuring mechanism 3 measures the difference between the position of the hook part of the fall arrester 7 at this time and the initial position, so as to judge the length of the fall arrester 7 being dragged and whether the self-locking of the fall arrester 7 is reliable and stable when hanging a heavy object. After testing a set of data, the test mechanism 5 moves the counterweight 505 to the initial position to wait for the next test. During the test process, different weights of counterweights 505 need to be replaced in order to obtain different data.

[0035] The measuring mechanism 3 includes two moving seats 301. A height measuring instrument is arranged inside the moving seat 301. The inner wall of the moving seat 301 is slidably connected to the outer wall of the column 2. An infrared generator 302 is arranged inside the moving seat 301. The infrared rays emitted by the infrared generator 302 contact the hook and the data of the height measuring instrument can be read only when the hook is stable. A hollow rod 303 is fixedly connected to the outer wall of the moving seat 301. One end of the hollow rod 303 away from the moving seat 301 is fixedly connected to a mounting block 304. A limiting ring 305 is fixedly connected to the outer wall of the mounting block 304. Elastic rods 306 are uniformly arranged on the outer wall of the limiting ring 305. The elastic rods 306 are made of rubber, and the inner wall of the elastic rod 306 is rotatably connected to the outer wall of the limiting ring 305.

[0036] Initially, both groups of moving seats 301 are at the position horizontal with the hook of the fall arrester 7. When the counterweight 505 falls and is stabilized, one group of moving seats 301 moves downward until the infrared rays coincide with the position of the hook, and the data of the two height measuring instruments are recorded at this time. The difference is the falling distance of the fall arrester 7. The hollow rod 303 drives the limiting ring 305 to surround the bottom of the fall arrester 7, making the elastic rods 306 close to the main body of the fall arrester 7, reducing the sway of the fall arrester 7, promoting the main body of the fall arrester 7 to quickly stabilize, facilitating quick reading and measurement. The position of the hook is determined by the infrared generator 302, which is more accurate than manual measurement.

[0037] The testing mechanism 5 includes a mounting plate 501. The inner wall of the mounting plate 501 is slidably connected to the outer wall of the screw rod 4. A return component 503 is fixedly connected to the bottom of the mounting plate 501. Limiting components 502 are symmetrically arranged on the inner wall of the mounting plate 501. A placing component 504 is fixedly connected to the outer wall of the return component 503. The testing mechanism 5 further includes a counterweight 505. The bottom of the counterweight 505 is in contact with the top of the placing component 504. A hanging ring 506 is fixedly connected to one end of the counterweight 505 away from the placing component 504. The outer wall of the hanging ring 506 is in contact with the inner wall of the limiting component 502.

[0038] Initially, the mounting plate 501 moves so that the placing component 504 contacts the top of the base 1, facilitating the worker to place the counterweight 505 on the placing component 504. Then, the hanging ring 506 of the counterweight 505 is placed inside the limiting component 502. Subsequently, the mounting plate 501 drives the limiting component 502 to move upward to a suitable position and maintains the stability of the placing component 504. During the upward movement of the limiting component 502, the limiting component 502 hooks the hanging ring 506 of the counterweight 505 with the hook of the anti-falling device 7. Subsequently, the placing component 504 causes the counterweight 505 to fall, pulling the anti-falling device 7 downward. At this time, the limiting component 502 moves downward, and the rope inside it close to the anti-falling device 7 reduces the sway amplitude of the rope rapidly, and cooperates with the return component 503 to quickly stabilize the counterweight 505, facilitating the measuring mechanism 3 to measure. After the measurement is completed, the return component 503 lifts the counterweight 505 and places the counterweight 505 well with the cooperation of the placing component 504, restoring the counterweight 505 to the height before the test, and conducting the measurement again, improving the test rate and saving a large amount of time for hundreds or thousands of experiments.

[0039] Embodiment 2, please refer to Figures 1-8 , the present invention provides a technical solution: on the basis of Embodiment 1, the limiting component 502 includes a telescopic column 5021. One end of the telescopic column 5021 is fixedly connected to the inner wall of the mounting plate 501. The other end of the telescopic column 5021 is fixedly connected to a fixing frame 5022. Arc-shaped rods 5023 are symmetrically arranged on the outer wall of the fixing frame 5022. The outer wall of the arc-shaped rod 5023 is fixedly connected to the outer wall of the fixing frame 5022. A bent plate 5024 is fixedly connected to one side of the outer wall of the fixing frame 5022 away from the arc-shaped rod 5023. The bent plate 5024 is made of a deformable material. A limiting plate 5025 is fixedly connected to one end of the bent plate 5024 away from the fixing frame 5022. An arc-shaped block 5026 is fixedly connected to one side of the limiting plate 5025 away from the bent plate 5024. The arc-shaped block 5026 fits the outer wall of the hook, and the outer wall of the arc-shaped block 5026 is in contact with the bottom of the anti-falling device 7.

[0040] At the beginning, the worker places the hanging ring 506 inside the two sets of arc-shaped rods 5023 and places it vertically. During the upward movement of the shelf board 501, the fixed frame 5022 drives the bent plate 5024 to rotate, so that the limiting plate 5025 contacts both sides of the hook, clamps the hook without applying pressure. When the hanging ring 506 approaches the hook, the hook rotates a certain angle under the action of the arc-shaped block 5026, so that the hanging ring 506 is buckled with the hook. Then the limiting plate 5025 releases the hook, and the counterweight 505 falls downward. The shelf board 501 remains stationary, and the telescopic column 5021 drives the arc-shaped rods 5023 to approach each other, so that the arc-shaped rods 5023 enclose the rope of the anti-falling device 7, rapidly reducing the swaying amplitude of the rope. The shelf board 501 moves downward, making the rope quickly maintain vertical stability. At this time, the infrared generator 302 moves to a position at the same height as the hook at this time and quickly conducts measurement, avoiding excessive swaying and floating of the counterweight 505, which may cause impact on the interior of the equipment and damage the equipment. At the same time, it avoids the detachment of the counterweight 505 during the swaying process, resulting in rolling after it falls and injuring the staff.

[0041] The returning component 503 includes a driving block 5031. The top of the driving block 5031 is fixedly connected to the bottom of the shelf board 501. There are two symmetrically arranged driving blocks 5031. A bent rod 5032 is rotatably connected to the opposite sides of the driving block 5031. At the beginning, the bent rod 5032 drives the receiving plate 5033 and the elastic rope 5036 away from the placing component 504. A receiving plate 5033 is rotatably connected to the opposite sides of the bent rod 5032. The receiving plate 5033 is made of a material with less friction. One end of the bent rod 5032 away from the driving block 5031 is rotatably connected to a connecting rod 5034. The bottom of the connecting rod 5034 is rotatably connected to a reel 5035. Elastic ropes 5036 are symmetrically arranged on the outer wall of the reel 5035, and the outer walls of the elastic ropes 5036 are fixedly connected to the outer wall of the reel 5035.

[0042] After the placing component 504 drops the counterweight 505, the bent rod 5032 drives the elastic rope 5036 to gradually approach the rope of the anti-falling device 7. By continuously winding the elastic rope 5036 through the reel 5035, the elastic rope 5036 controls the swaying of the rope, and cooperates with the limiting component 502 to quickly stabilize the counterweight 505. When the receiving plate 5033 falls off after the counterweight 505 drops, it buffers the counterweight 505 to avoid the counterweight 505 flying out. After the measurement is completed, the bent rod 5032 drives the receiving plate 5033 to approach the counterweight 505, and lifts the counterweight 505 during the rotation process, and cooperates with the placing component 504 to return the counterweight 505 to its original position. During this process, the limiting component 502 keeps the hanging ring 506 stationary, and the counterweight 505 can be lifted and reset without manual labor, which is convenient for conducting multiple tests and saves test time.

[0043] The placement component 504 includes a rotating shaft 5041. The outer wall of the rotating shaft 5041 is rotatably connected to the outer wall of the driving block 5031. One end of the rotating shaft 5041 away from the driving block 5031 is fixedly connected to a placement plate 5042. Inside one end of the placement plate 5042 away from the rotating shaft 5041, there is a telescopic rod 5043. The outer wall of the telescopic rod 5043 is sleeved with the inner wall of the placement plate 5042. One end of the telescopic rod 5043 away from the placement plate 5042 is fixedly connected to the outer wall of the driving block 5031. The bottom of the placement plate 5042 is fixedly connected to a connecting rope 5045. The connecting rope 5045 is elastic. One end of the connecting rope 5045 is fixedly connected to a sliding rod 5044. The bottom of the sliding rod 5044 is rotatably connected to the top of the base 1. The top of the sliding rod 5044 is in contact with the bottom of the placement plate 5042.

[0044] Initially, the support plate 501 drives the placement plate 5042 to contact the top of the base 1. The sliding rod 5044 is located inside the base 1. After the support plate 501 rises, the base 1 drives the sliding rod 5044 to rotate so that it contacts and supports the bottom of the placement plate 5042. At this time, the placement plate 5042 is locked by the telescopic rod 5043 to support the counterweight 505. After the hook is hooked, the telescopic rod 5043 retracts, the sliding rod 5044 rotates back inside the base 1, and the placement plate 5042 naturally droops around the rotating shaft 5041, causing the counterweight 505 to naturally fall. After the measurement is completed, the rotating shaft 5041 rotates, and together with the return component 503, the bottom of the counterweight 505 contacts the top of the placement plate 5042. At this time, the sliding rod 5044 supports the bottom of the counterweight 505. Subsequently, the sliding rod 5044 rotates again inside the base 1, causing the counterweight 505 to rise and then fall again. Repeat the operation until different weights of counterweights 505 are replaced, making the test process smoother and shortening the test time.

[0045] The specific working process is as follows:

[0046] Initially, the worker places the counterweight 505 on the test mechanism 5 and hangs the anti-falling device 7 on the top plate 6. Subsequently, the test mechanism 5 drives the counterweight 505 to move upward. During the movement of the test mechanism 5, the counterweight 505 is hooked to the hook of the anti-falling device 7. Both sets of moving seats 301 are located at positions horizontal to the hook of the anti-falling device 7. After the counterweight 505 falls and remains stable, one set of moving seats 301 moves downward until the infrared ray coincides with the position of the hook, and the data of the two height measuring instruments are recorded at this time. The difference is the falling distance of the anti-falling device 7.

[0047] During the test, when the limit component 502 rises, the hanging ring 506 of the counterweight 505 is hooked to the hook of the anti-falling device 7 by the limit component 502. Subsequently, the placement component 504 causes the counterweight 505 to fall, pulling the anti-falling device 7 downward by the counterweight 505. At this time, the limit component 502 moves downward, and the rope inside it near the anti-falling device 7 quickly reduces the sway amplitude of the rope. In cooperation with the reset component 503, the counterweight 505 is quickly stabilized, facilitating the measurement by the measuring mechanism 3. After the measurement is completed, the reset component 503 lifts the counterweight 505, and with the cooperation of the placement component 504, the counterweight 505 is placed properly, restoring the counterweight 505 to the height before the test, and then the measurement is carried out again. During the test, counterweights 505 of different weights need to be replaced in order to obtain different data.

[0048] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention.
