Referring to accompanying drawing 1, the safety lock detection device of the present invention also includes the following components: electric drive and control part (such as hoist, including motor and brake), safety lock fixture, data detection part and so on.

The safety lock fixture of the detection device of the present invention adopts an I-beam and locking bolt structure, and is detachably fixed on the first support frame A1. The purpose of detecting safety locks of different manufacturers and models can be achieved by changing the fixtures of different types of safety locks. In view of the different specifications and installation dimensions of swing arm anti-tilt safety locks on the market, the fixture design of this device adopts a different matching fixture for each safety lock. Through the investigation of various safety locks on the market, the diameter of the installation hole of the safety lock is about 12mm, the horizontal distance between the two installation holes is between 30mm and 60mm, and the thickness of the safety lock body is about 50mm. If there is a swing arm anti-tilt safety lock product with a new installation form and a new installation size on the market, it only needs to process a new fixture to cooperate with the use of the detection device, thereby expanding its versatility.

The difference in the installation dimensions of general safety locks is not only the difference in the position of the connecting bolts between the lock body and the basket body, but also the distance between the working rope and the safety rope. Therefore, the present invention can also allow the distance between the safety rope and the working rope to change within a certain range, except by changing different clamp devices, that is, the position of the first pulley A6 relative to the second support frame A9, the position of the first pulley A6 The position of the three pulleys A18 relative to the second retractable sliding bar A23 is an adjustable technical means. When detecting a safety lock, after measuring the distance, tighten the two plates with bolts to ensure that the working wire rope is vertical , so that the detected data may be closer to the actual situation. When it is necessary to detect another safety lock with a different form, loosen the fastening bolts, adjust the position between the large pulley and the small pulley relative to the bottom plate, thereby adjusting the distance between the wire ropes, and then tighten the bolts after adjustment, so that By changing the distance between the safety rope and the working rope

The working principle and action process of the present invention are described as follows.

When the hoisting weight A4 pulls the first rope A7 to move downward, the first pulley A6 and the second pulley A15 rotate clockwise, which drives the third pulley A18 to rotate counterclockwise. At this time, the second telescopic sliding The end near the third pulley A18 of the cross bar A23 moves upwards;

After taking out the third cylindrical pin B11, manually press down the pressure rod B1, and at this time, the fourth cylindrical pin B13 is driven to rotate counterclockwise, and the first perforated baffle B6 is jacked up. The first baffle plate with holes B6 drives the support gasket B5 to move rapidly to the right. At the same time, the first suspension rope A7 is quickly released, and the first limit rod B7 limits the support gasket B5, the first baffle plate with holes B6, The first sling A7 can only move along the direction of the first stop bar B7, and the end of the second telescopic sliding cross bar A23 near the third pulley A18 will produce a downward movement trend; at this time, the safety lock A10 will second The suspension rope A8 is locked to prevent the end of the second telescopic sliding cross bar A23 close to the A18 from moving downward.

Referring to accompanying drawing 1, during the test, first use the electric drag control part to drive the steel wire rope to lift the second telescopic sliding cross bar to a horizontal position, and the second telescopic sliding cross bar and the counterweight simulate the rated load capacity of the basket body. The wire rope simulates the normal working state of the electric hanging basket. The transmission part adopts a wire rope pulley block, and one end of the working wire rope penetrates into the hoist, and is connected with the decoupling part through the guide pulley. Then pass through the safety lock from the lower end of the safety rope, fix it on the fixture with bolts, and lean its swing arm against the working rope to keep it in an unlocked state. Stick a steel ruler with a length of 0.5m on the second support frame A9, and weld a pointer correspondingly on the right side of the second telescopic sliding cross bar, which can complete the reading work corresponding to the steel ruler and constitute the data detection part. Put two rectangular shock-absorbing rubber blocks under the bottom frame of the lock fixing system B as a buffer device to prevent the test frame from falling and being damaged due to the failure of the safety lock. This solution can accurately measure the parameters of the safety lock: the working distance of the safety lock when the hanging platform is suddenly weightless, the triggering angle of the safety lock when the hanging platform is slowly tilted, the sliding distance of the hanging platform under the weight of the hanging platform after the safety lock is locked, and Meet the design purpose. When the hanging basket is weightless and free fall detection, at first read the height value when it is still working, and pull out the pin shaft of the decoupling device on the right side of the second telescopic sliding cross bar (that is, by pressing down the depression bar B9), then The working rope will be unhooked instantly, which can simulate the sudden weightlessness of the electric hanging platform. After the safety lock and lock rope, read again at the place where the lock rope falls. The difference between the two readings is the distance from the lock rope under the weightless situation. When measuring the trigger angle of the safety lock when the hanging basket is slowly tilted, the motor control button can be used to drive the wire rope to move the left end of the second telescopic sliding cross bar upward until the safety lock is locked. According to the height difference between the front and rear of the lock rope of the left jib, and the data difference read from the scale, the distance of the lock rope can be calculated. The angle of the lock rope can be calculated from the conversion relationship between the distance and the angle. When measuring the sliding distance of the hanging basket under the action of its own weight after the safety lock is locked, according to the national industry standard on "Hanging Basket for High Places", when the hanging basket is subjected to a static test load, the safety lock rope slips for 1 hour The distance is not greater than 2 mm. At this moment, the second telescopic sliding cross bar can be moved up by the control button, so that the safety lock is in the state of locking the rope. Start counting from this moment, and after 1 hour, observe whether the distance that the left end of the second telescopic sliding cross bar moves down reaches the regulation of the industry standard.
