Description

Technical Field

[0001] This utility model relates to the field of automatic descent protector testing technology, and specifically to a testing device for automatic descent protectors. Background Technology

[0002] In rock climbing and high-altitude operations, the safety of climbers is paramount. Belay equipment avoids the reliance on manual operations, such as rope pulling or lowering, which are not only labor-intensive but also inherently unsafe. In recent years, the emergence of automatic descent belay devices has solved this manual operation problem, saving time and increasing efficiency, significantly reducing labor costs in climbing gyms, and allowing for long-term use. To use, the sling of the automatic descent belay device is extended, and the rigging buckle on the sling is connected to the climber's harness. After reaching a height, the braking force generated by the belay device during descent allows the climber to descend smoothly to the ground.

[0003] To ensure product safety, regular annual maintenance and descent time testing are required to ensure the descent time is within the standard range. The test time reflects the braking force of the safety device; too little braking force will cause the person to descend too quickly, while too much will cause them to descend too slowly, especially for lighter individuals. However, current testing methods for automatic descent safety devices require a sling length of at least 8 meters. This necessitates a test tower of a certain height (at least 6 meters) to hold the sling with a fixed-weight counterweight, simulating a person descending while attached to the safety device. While this method allows for testing, it requires sufficient space and height, and the cost of building the test tower is high. Once built, the tower cannot be moved and testing is limited to a designated location, resulting in poor flexibility and failing to meet the needs for efficient and flexible testing.

[0018] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] like Figure 1 and Figure 2 As shown, this utility model discloses a testing device for an automatic slow-descent protector, comprising a test mounting frame 1, a motor drive assembly 2, a roller 3, and a controller. The test mounting frame 1 is provided with a winding mounting table 11, a rotating shaft, and a test locking frame 12. The motor drive assembly 2 is fixedly mounted on the winding mounting table 11. The roller 3 is fixedly sleeved on the rotating shaft, and the rotating shaft is rotatably mounted on the test mounting frame 1. The test locking frame 12 can fix the automatic slow-descent protector 4. The moving end of the motor drive assembly 2 is connected to the rotating shaft, and the motor drive assembly 2 can drive the roller 3 to rotate. The roller 3 is provided with a locking part and a winding part. The locking part can lock the flat strip of the automatic slow-descent protector 4, and the winding part can cooperate with the motor drive assembly 2 to wind and position the flat strip of the automatic slow-descent protector 4.

[0021] With the cooperation of motor drive component 2 and roller 3, motor drive component 2 drives roller 3 to rotate. Roller 3 rotates and retracts the flat strip of automatic slow-descent protector 4. After pulling out the flat strip of a specified length, it automatically stops rotating. At the same time, the controller can automatically obtain the time required to retract the flat strip of the specified length, which effectively improves the flexibility of the test equipment, saves height and space, and directly obtains data through the controller, which effectively improves the test experience of the testers and can meet the needs of efficient and flexible testing.

[0022] The working principle of the testing device is mainly based on the constant torque output mode of the motor drive component 2 (that is, the motor drive component 2 can maintain a constant torque output when the load changes, ensuring the stability and accuracy of the mechanical system), simulating a heavy object to pull the flat belt, measuring the time taken for the flat belt to reach a specified length of the protector, and thus determining whether the braking force of the protector is within the required range.

[0023] The testing standards are set according to the situation. For example, with a normal protector, the time to pull out 6 meters of slack should be controlled between 6 and 7 seconds. If the braking force of the protector is too large, the time to pull out 6 meters of slack will be greater than 7 seconds; if the braking force of the protector is too small, the time to pull out 6 meters of slack will be less than 6 seconds. Maintenance is required for protectors with braking forces that are too large or too small.

[0024] The locking part is a fastener 31 set on the side of the roller 3. By setting the fastener 31, the lifting lock on the flat belt of the automatic slow-descent protector 4 can be fixed on the fastener 31 before the test, so as to prevent the flat belt from falling off when the roller 3 is rotated and stored, thus improving the accuracy of the test.

[0025] The winding section is a winding platform 32 set on the outer contour of the roller 3, and a limit baffle 33 is provided on the side of the winding platform 32.

[0026] By setting the limit baffle 33, the flat strip can be placed on the winding platform 32 during the flat strip storage process, avoiding the flat strip from falling off and improving the accuracy of the test.

[0027] Both sides of the winding platform 32 are provided with limit baffles 33, and one of the limit baffles 33 is provided with an air-avoiding opening 331. The air-avoiding opening 331 can cooperate with the flat belt of the automatic slow-descent protector 4 to pass through and connect with the fixing member 31.

[0028] With limit baffles 33 installed on both sides of the winding platform 32, the stability of the flat strip storage can be further improved. With the setting of the clearance opening 331, the tester can first pass the flat strip through the clearance opening 331 before the test preparation work, then fix the lifting lock on the fixing part 31, and then place the flat strip on the winding platform 32, which provides a guarantee for accurate testing.

[0029] Multiple winding posts 34 are also provided on the side of the roller 3. The multiple winding posts 34 and the fixing member 31 are arranged on the same side of the roller 3, and the multiple winding posts 34 and the fixing member 31 are distributed in a ring on the side of the roller 3.

[0030] By setting multiple winding posts 34, the stability of the lifting lock on the fixing member 31 can be further improved. Before placing the flat strip on the winding platform 32, the flat strip is first wrapped around the outside of the multiple winding posts 34 and the fixing member 31 to improve the stability of the flat strip in the locking part.

[0031] The test locking bracket 12 is provided with a mounting groove that cooperates with the automatic slow-descent protector 4. The mounting groove is provided with locking holes that penetrate both sides of the mounting groove, and locking parts 121 are provided in the locking holes.

[0032] The automatic slow-descent protector 4 can be fixed on the test locking frame 12 by the cooperation of the locking hole and the locking part 121, providing a basis for subsequent stability testing.

[0033] The upper end of the automatic slow descent protector 4 is inserted into the mounting groove, and the locking member 121 passes through the locking hole and the upper end of the automatic slow descent protector 4 in sequence and is locked.

[0034] The motor drive assembly 2 includes a motor body 21, a reducer 22, and a linkage assembly. The moving end of the motor body 21 is connected to the reducer 22, the moving end of the reducer 22 is connected to one end of the linkage assembly, and the other end of the linkage assembly is connected to the rotating shaft.

[0035] By setting up the reducer 22 and the linkage components, the torque and rotational force of the motor body 21 can be effectively controlled.

[0036] The linkage assembly includes a linkage component 23, a large gear 24, and a small gear 25. The small gear 25 is fixed to the moving end of the reducer 22, the large gear 24 is fixed to one end of the rotating shaft, and the linkage component 23 is sleeved on the large gear 24 and the small gear 25.

[0037] Linkage component 23 can be a chain or a belt.

[0038] The rotating component is a rotating shaft 5. The test mounting frame 1 is equipped with a rotating connecting seat 6 that mates with both ends of the rotating shaft 5. The rotating shaft 3 and the rotating connecting seat 6 can be rotatably connected.

[0039] As can be seen from the above, the beneficial effects of this utility model are: it can effectively solve the problems of large space occupation, high cost and poor flexibility of the test equipment for automatic slow-descent protector 4 in the prior art. Through the cooperation of motor drive component 2 and roller 3, motor drive component 2 drives roller 3 to rotate. Roller 3 rotates and collects the flat strip of automatic slow-descent protector 4. After pulling out the flat strip of a specified length, it automatically stops rotating. At the same time, the controller can automatically obtain the time required to collect the flat strip of the specified length, which effectively improves the flexibility of the test equipment, saves height and space, and directly obtains data through the controller, which effectively improves the test experience of the testers and can meet the needs of efficient and flexible testing.

The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
