Description

Technical Field

[0001] This invention relates to the field of high-altitude operation technology in the power industry, and in particular to intelligent safety belt quality testing equipment. Background Technology

[0002] With the advancement of industrialization, the power industry, as a fundamental sector supporting the national energy system and economic development, presents a complex working environment and inherent risks that cannot be ignored. High-altitude operations in the power industry, especially in complex environments such as high-voltage power towers and substations, have always placed a high priority on worker safety for industry managers and safety supervision departments. Statistics show that accidents related to high-altitude operations are frequent, and most are closely related to workers failing to wear safety belts correctly or to the quality of the safety belts. Although safety belt designs are constantly being improved, many factors can still prevent them from providing the intended protection in actual use.

[0003] Existing technologies for seat belt inspection rely on traditional manual visual inspection, which carries the risk of missed or false detections and cannot accurately and effectively detect potential problems with the seat belts. Especially in the power industry, where working conditions are complex and harsh, manual inspection is insufficient to ensure comprehensive quality. Furthermore, existing seat belt quality testing equipment typically tests the quality of the seat belt by applying gradually increasing tension, which cannot simulate the situation of an operator suddenly losing their footing and falling. Summary of the Invention

[0004] To address the above shortcomings, this invention provides an intelligent seatbelt quality testing device. By connecting a first hook assembly and a second hook assembly to the head and waist sections of the prosthesis respectively, in the event of a sudden disconnection of the first hook assembly, a first tension sensor connected to the second hook assembly detects the stress on the seatbelt. The device then determines whether the seatbelt is qualified based on its usage. The specific technical solution is as follows: The intelligent seat belt quality inspection equipment includes: a cubic connecting frame, a first hook assembly and a second hook assembly mounted on the upper part of the connecting frame, an electromagnetic chuck assembly that can be controlled to engage and disengage below the first hook assembly, the lower end of the electromagnetic chuck assembly being connected to the head of a simulated human, a seat belt being fitted around the waist of the simulated human, and the second hook assembly including a first tension sensor fixedly connected to the connecting frame, a hanging ring being connected to the lower part of the first tension sensor, and the hanging ring being connected to the hook of the seat belt.

[0005] Preferably, the other end of the first hook assembly is connected to a first drive module for controlling the lifting and lowering of the working end of the first hook assembly.

[0006] Preferably, the first drive module is assembled and connected to the lower part of the connecting frame, and the connecting frame is assembled and connected to a first pulley group for changing the direction of the force, and the traction rope connected between the first drive module and the first hook assembly is wound around the first pulley group.

[0007] Preferably, the lower part of the connecting frame is equipped with a wheel module, which consists of two directional wheels on one side and two omnidirectional wheels on the other side.

[0008] Preferably, the connecting frame is a cuboid frame, and the connecting frame is equipped with side sealing plates for sealing the upper, lower, rear and left and right sides of the connecting frame. The front side of the connecting frame is equipped with an openable door panel.

[0009] Preferably, a buckle test module is assembled and connected to one side of the connecting frame.

[0010] Preferably, the buckle testing module includes a bracket, with a first fixing member and a second fixing member connected to both ends of the bracket for clamping the buckle of the seat belt. The first fixing member is equipped with a second tension sensor, the second tension sensor is fixedly connected to the bracket, and the second fixing member is connected to a second drive module via a traction rope.

[0011] Preferably, the second drive module is located below one end of the first fixing member, and the bracket is equipped with a second pulley group for changing the direction of the traction rope, the second pulley group being located below the second fixing member.

[0012] Preferably, a detection camera module for observing the wear of the seat belt is mounted and connected to the upper side of the bracket.

[0013] Preferably, a control display module for controlling the operation of the first drive module, the electromagnetic chuck assembly, and the second drive module is assembled and connected to the other side of the connecting frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention can monitor various performance indicators of seat belts in real time, such as strength, tension, and wear, through precise sensing technology.

[0015] 2. Compared with traditional manual inspection methods, intelligent inspection equipment can more comprehensively and accurately detect potential problems with safety belts, provide timely warnings, and prevent accidents caused by safety belt malfunctions during operation, greatly improving work safety. It can achieve comprehensive inspection of safety belts, significantly shorten inspection time, avoid the tediousness and drawbacks of manual inspection, and improve the work efficiency of workers and the safety of the working environment.

[0016] 3. This invention can achieve simultaneous detection of the seat belt and the seat belt buckle, so that the status of both can be captured simultaneously, avoiding the omission of potential safety problems due to the detection of only one component.

[0017] 4. Through the cooperation of the first hook assembly and the second hook assembly, when the electromagnetic chuck assembly connected to the first hook assembly is de-energized, the present invention simulates the situation where the operator suddenly loses the point of force. The first tension sensor connected to the second hook assembly measures the force and can obtain the usage status of the safety belt at the same time, thus realizing the detection of the safety belt while simulating the construction scenario.

[0018] 5. This invention can simulate various usage scenarios of seat belts, including instantaneous descent and elevation, providing a more comprehensive test of seat belts and improving their safety.

[0019] 6. This invention achieves intelligent control during the detection process through a control display module, and displays the results through signal transmission. Attached Figure Description

[0033] Example 1: like Figures 1-8 As shown: An intelligent seat belt quality inspection device includes a cubic connecting frame 1. The upper part of the connecting frame 1 is equipped with a first hook assembly 2 and a second hook assembly 3. The lower part of the first hook assembly 2 is connected to an electromagnetic chuck assembly 4 that can be controlled to engage and disengage. The lower end of the electromagnetic chuck assembly 4 is connected to the head of a mannequin 5. A seat belt 6 is fitted around the waist of the mannequin 5. The second hook assembly 3 includes a first tension sensor 33 that is fixedly connected to the connecting frame 1. The lower part of the first tension sensor 33 is connected to a hanging ring 32, which is connected to the hook of the seat belt 6. In this embodiment, the connecting frame 1 is used to assemble the first hook assembly 2 and the second hook assembly 3. Below the first hook assembly 2 are the electromagnetic chuck assembly 4 and the head of the phallus. The electromagnetic chuck assembly 4 uses the electromagnetic principle to generate magnetic force by energizing the internal coil. Through the magnetic guide panel, it tightly attracts the phallus wearing the seat belt 6. When the coil is de-energized, the magnetic force disappears, the phallus is demagnetized, and the phallus falls off. Only the second hook assembly 3 is hooked to the waist of the phallus 5. The first tension sensor 33 measures the force on the seat belt, thereby testing the seat belt to determine the force on the seat belt and simulating the situation where a person suddenly loses their point of support. Preferably, the sensor fixing base 31 is made of stainless steel and is a rectangular plate, mainly used to fix and install the first tension sensor 33. The first tension sensor 33 is located between the sensor fixing base 31 and the hanging ring 32.

[0034] Reference Figure 6 The other end of the first hook assembly 2 is connected to a first drive module 7 for controlling the lifting and lowering of the working end of the first hook assembly 2. In this embodiment, the first drive module 7 is a seat belt detection power module, mainly used to pull up the seat belt 6 to simulate the suspension when a person is wearing the seat belt and is subjected to force; the first drive module 7 controls the lifting and lowering of the spur 5, and during the lifting and lowering of the spur 5, it simulates the force on the seat belt 6 during the lifting and lowering of a person, and the first tension sensor 33 detects the force on the seat belt 6.

[0035] Reference Figure 6 The first drive module 7 is assembled and connected to the lower part of the connecting frame 1. The connecting frame 1 is equipped with a first pulley group 8 for changing the direction of the force. The traction rope connecting the first drive module 7 and the first hook assembly 2 is wound around the first pulley group 8. In this embodiment, the position of the first drive module 7 is further defined. The traction rope connecting the first drive module 7 and the hook first hook assembly 2 is in an n-shape. The first pulley group 8 consists of two fixed pulleys and a pulley bracket. The two fixed pulleys are installed at the corner position of the n-shape.

[0036] Reference Figure 5The lower part of the connecting frame 1 is equipped with a wheel module 9, which consists of two directional wheels on one side and two omnidirectional wheels on the other side. In this embodiment, the wheel module 9 is the bottom walking module of the device, consisting of two omnidirectional wheels and two directional wheels, and has a locking mechanism to ensure that there is no displacement during the testing process, providing strong mobility and easy movement.

[0037] Reference Figures 1-2 The connecting frame 1 is a rectangular frame. Side sealing plates 11 are assembled and connected to the connecting frame 1 to enclose the upper, lower, rear, and left and right sides of the connecting frame 1. An openable door panel 12 is assembled on the front side of the connecting frame 1. In this embodiment, preferably, the side sealing plates 11 and the door panel are made of stainless steel, mainly used to protect and fix the internal modules of the device.

[0038] Example 2: Reference Figure 1 and Figures 7-8 A buckle testing module 10 is mounted on one side of the connecting frame 1. The buckle testing module 10 includes a bracket 101, with a first fixing member 102 and a second fixing member 103 connected to both ends of the bracket 101 for clamping the buckle 14 of the seat belt. A second tension sensor 104 is mounted on the first fixing member 102 and fixedly connected to the bracket. The second fixing member 103 is connected to a second drive module 105 via a traction rope. In this embodiment, the first fixing member 102 and the second fixing member 103 of the buckle testing module 10 are made of stainless steel and are designed with special clamps to clamp the seat belt buckle without damaging it. The second tension sensor 104 mainly converts the physical signal of the tension of the device into a measured electrical signal, which is then output to the display module. The second drive module 105 is the power structure for buckle testing, realizing the pulling of the buckle.

[0039] Reference Figure 7 and Figure 8 The second drive module 105 is located below one end of the first fixing member 102. A bracket 101 is fitted with a second pulley assembly 106 for changing the direction of the traction rope. The second pulley assembly 106 is located below the second fixing member 103. In this embodiment, the traction rope is arranged in a U-shape, with the opening facing one side of the second drive module 105. The second pulley assembly 106 includes two fixed pulleys and a pulley bracket, and the traction rope is wound around the fixed pulleys. It should be noted that the traction rope is preferably a traction steel wire rope, composed of multiple strands of steel wire, which has high tensile strength.

[0041] Reference Figures 1-5 On the other side of the connecting frame 1, a control and display module 13 is mounted and connected to control the operation of the first drive module 7, the electromagnetic chuck assembly 4, and the second drive module 105. The control and display module 13 is the core of the device's control, responsible for managing the equipment's operation process, controlling the testing process, and monitoring all sensor data in real time. The PLC control system and the human-machine interface of the display module are combined to realize intelligent and automated control of the equipment.

[0042] Working principle: When testing the safety belt, the safety belt 6 to be tested is first worn on the dummy 5, and the traction rope is hung on the safety belt 6 to simulate the state of a worker wearing the safety belt 6 while performing high-altitude power operations. The head and waist of the dummy 5 are connected to the first hook assembly 2 and the second hook assembly 3, respectively. The electromagnetic chuck assembly 4 is attached to the hook connected to the dummy, and then the first drive module 7 drives the dummy 5 to rise. During the rise, the first tension sensor 33 detects the force on it. The descent is the same. Finally, the dummy is stabilized at a certain height, the electromagnetic chuck assembly 4 is released, and the dummy falls. In this way, the instantaneous tension of the safety belt is measured.

[0043] When testing the seat belt buckle 14, the two ends of the buckle are first clamped by the first fixing component 102 and the second fixing component 103. Then, the second drive module 105 pulls the traction rope to simulate the buckle 14 being under tension. The second tension sensor 104 detects the force on the buckle. At the same time, the detection camera module 107 transmits the obtained image to the control display module 13.
