Description

Technical Field

[0001] The invention relates to the field of mine hoists, and in particular to a visual detection device for a mine hoist bucket shock-absorbing hook. Background Art

[0002] The main shaft hoist of the mine is mainly used to transport ore and raw coal, and the loading container is a skip. There are two types of skips: bottom unloading type and side inclined type, and generally two methods of unloading are used: curved track unloading or hydraulic push rod unloading. Regardless of which unloading method is used for the skip, after unloading is completed, the gate needs to return to its original position, and the mechanical hook must be accurately in place before the hoist can operate.

[0003] The bucket hook device proposed in the Chinese invention patent application number: CN201911324988.6 includes a hook assembly with a hook at the end, and a hook slot assembly corresponding to the hook assembly, wherein the hook slot assembly includes a first vertical plate fixed in parallel to the bucket box frame, the first vertical plate is parallel to the connecting vertical plate, and is combined with the connecting vertical plate and the bottom plate to form a fixed slot, the hook is clamped in the fixed slot, the connecting vertical plate is parallel to the second vertical plate, a pair of ribs are arranged between the connecting vertical plate and the second vertical plate, the two ribs are arranged at an angle and are combined with the connecting vertical plate and the second vertical plate to form an air duct, the cross section of the air duct parallel to the second vertical plate is a trumpet shape with a wide bottom and a narrow top, and a parallel inverted V-shaped baffle is arranged directly above the fixed slot and the air duct, and the end of the inverted V-shaped baffle is fixed to the frame of the bucket box frame. The trumpet-shaped air duct is used to increase the pressure of the airflow in the mine tunnel and blow the mine dust out of the fixed slot.

[0004] Traditional gate hook detection mainly relies on visual inspection and manual operation by operators, which is not only inefficient but also prone to misjudgment or negligence due to human factors. With the development of automation technology, people have begun to try to use contact sensors to monitor the status of gate hooks in real time.

[0005] In the prior art, the vibration and impact generated by the bucket during movement will also have a serious impact on the stability and reliability of the sensor. The inner lining lacks sufficient shock absorption and sound insulation performance, and cannot effectively reduce the impact of vibration on the sensor. The bearing of the rotating shaft is not a sealed deep groove ball bearing, or the surface hardness is not enough to ensure wear resistance in long-term use. The defects of the data connection line pipe, port and tapping port cannot ensure the stable transmission of data, which is easily interrupted by vibration or impact. The replacement of the sealing plate requires the disassembly of the entire device, which increases the difficulty and time cost of maintenance. The guide limit rod lacks fine-tuning function and cannot adapt to different shaft installation errors. The lack of ventilation holes in the bottom plate leads to equipment overheating problems. The sensor buffer shock absorption mechanism has poor impact resistance and cannot withstand the impact of free fall from a certain height. The material of the circular shock-absorbing plate is not resistant to high temperature and is not suitable for high-temperature mine environments. The installation and maintenance process of the sensor unit is complicated, which is not conducive to quickly and conveniently fixing or releasing the sensor. The locking rod and the pressing telescopic elastic ring are not user-friendly, which increases the difficulty of operation. The existing device lacks an integrated alarm system and cannot immediately notify the operator when an abnormality is detected, which delays the time to respond to emergencies. The visual detection data processing module does not have the function of evaluating the fatigue life of materials and cannot accurately predict potential safety hazards. The unreasonable data connection pipes, ports and tap ports make it impossible to ensure data integrity and transmission efficiency in the vibration environment generated during the operation of the skip. Therefore, we propose a visual detection device for the shock-absorbing hook of the mine hoist skip. Summary of the invention

[0019] Compared with the prior art, the present invention has the following beneficial effects: In the scheme of the present invention, by providing a buffer groove and a shock absorbing spring, the sensor can be effectively protected from physical damage and its service life can be extended. The buffer shock absorbing disc, the fan-shaped sheet and the buffer groove form a shock absorbing system. The buffer groove on the fan-shaped sheet provides an insertion space for the sensor buffer rod, which can further increase the shock absorbing effect. When vibration occurs, the shock absorbing disc and its structure can disperse and absorb the vibration energy, thereby protecting the sensor from damage.

[0020] The sensor buffer rod is connected to the linkage telescopic rod through a hinged cap, allowing relative movement within a certain range to adapt to the movement of the bucket and reduce direct impact on the sensor. The sensor mounting slot provides a stable platform for the sensor to be fixed, ensuring that the sensor can maintain the correct detection direction and position even under harsh conditions. The combination of the linkage telescopic rod and the telescopic rod sleeve allows the sensor unit to be flexibly displaced within a certain range to adapt to the position change of the bucket hook. This can reduce the sensor position deviation caused by equipment movement and improve detection accuracy.

[0021] The shock-absorbing plate assembly is embedded in the buffer shock-absorbing disc. The shock-absorbing plate mounting holes and positioning grooves on the circular shock-absorbing plate provide precise installation and positioning to better play the shock-absorbing role. The combination of the spring mounting plate and the shock-absorbing spring provides additional elastic buffering to cope with impacts and vibrations from different directions.

[0022] The serrated holes, fixing plates and mounting locking rods are used to position and fix the shock absorber, ensuring that the shock absorber remains stable when subjected to impact and vibration. The serrated holes are helpful in reducing weight while maintaining structural strength, the fixing plates are used to lock the position of the shock absorber, and the mounting locking rods further ensure the stability of the entire sensor unit.

[0023] The outer panel is made of corrosion-resistant galvanized steel, and the inner lining has good shock absorption and sound insulation performance. The rotating shaft adopts sealed deep groove ball bearings, which can withstand large radial and axial loads, and the surface hardness is HRC58-62, ensuring wear resistance in long-term use.

[0024] The combination of the shock-absorbing disc and the fan-shaped piece effectively absorbs shock and vibration, protecting the sensor from damage. The data connection tube, port and tap port ensure stable data transmission and avoid interruption caused by vibration or impact.

[0025] The rotating shaft is equipped with an automatic lubrication system, which uses food-grade lubricating oil and automatically lubricates it every 4 hours to ensure that the rotating shaft will not wear out during long-term operation.

[0026] The sealing plate has a quick-change mechanism, which allows it to be replaced in just 30 minutes without disassembling the entire device.

The bottom plate is equipped with multiple ventilation holes to promote air circulation inside the box and prevent the equipment from overheating.

[0028] The sensor buffer mechanism has been tested for impact resistance and can withstand the impact of a free fall from a height of 1 meter without damage. The material of the circular shock absorber can withstand temperatures up to 150°C and is suitable for mines that encounter high temperature environments.

[0029] By pressing the telescopic elastic ring component, the installation and maintenance process of the sensor unit is simplified, allowing the operator to quickly and conveniently fix or release the sensor.

[0030] The integrated alarm system can immediately notify operators when an anomaly is detected, increasing the response time to emergency situations. The visual inspection data processing module provides a quantitative method to evaluate the durability of materials under repeated stress.

[0031] The data connection line pipes, ports and tap ports ensure stable data transmission, and can ensure data integrity and transmission efficiency even in the vibration environment generated during the operation of the skip.

[0032] The whole device has a simple structure, and the functions of each component are clear, easy to operate and maintain. By real-time monitoring of the stress, fatigue and cracks of the bucket hook, potential safety hazards can be discovered in time, thus preventing accidents. BRIEF DESCRIPTION OF THE DRAWINGS

[0075] The function and effect of the formula is to determine the number of reciprocating cycles that a material can withstand under a certain stress amplitude, i.e., fatigue life. By adjusting the parameters in the formula and It can adapt to the fatigue characteristics of different materials. Since b is a negative value, when the stress amplitude When N increases f The value of will decrease, which means that the fatigue life of the material will be shortened, and vice versa. In summary, this formula provides a quantitative method to evaluate the durability of materials under repeated stress.

[0076] Working principle: When the bucket generates vibration and impact during movement, the sensor buffer shock absorption mechanism absorbs and disperses this energy through the physical structure. In particular, the combination of the buffer shock absorption disc 171 and the fan-shaped sheet 172, and the shock absorption sheet assembly 19 and the circular shock absorption sheet 191 work together to form an effective shock absorption system. This system can reduce the direct impact on the sensor, protect the sensor from damage, and ensure the accuracy of the measurement data.

[0077] The connection between the sensor buffer rod 173 and the linkage telescopic rod 175 allows the sensor to freely expand and contract with the movement of the bucket within a certain range, thereby adapting to the change of the hook position. This reduces the sensor position deviation caused by the movement of the equipment and improves the detection accuracy.

[0078] The data connection conduit 18, the data connection port 181 and the data connection tap port 182 ensure that the data transmission from the sensor to the control system is stable and reliable, and the integrity and transmission efficiency of the data can be guaranteed even in the vibration environment generated during the operation of the bucket.

[0079] The installation and maintenance process of the sensor unit is simplified by installing the locking rod 22 and pressing the telescopic elastic ring 221. These components allow the operator to quickly and conveniently fix or release the sensor.

[0080] Fix the sensor on the sensor buffer rod 173 through the sensor installation slot 174; then, insert the buffer rod into the buffer groove 1721 of the fan-shaped piece 172 on the buffer shock-absorbing disc 171; use the cooperation of the linked telescopic rod 175 and the telescopic rod sleeve 176 to adjust the sensor to a suitable position; finally, lock the entire sensor unit by installing the locking rod 22 and pressing the telescopic elastic ring 221 to ensure its stability.

[0081] As the bucket moves, if it encounters vibration and impact, the buffering and shock-absorbing mechanism starts to work, dispersing and absorbing the impact force, and protecting the sensor core components. At this time, the linkage telescopic rod 175 automatically adjusts the length according to the movement of the bucket to keep the correct position of the sensor.

[0082] The data collected by the sensor is transmitted to the data connection port 181 and the tap port through the lines in the data connection line pipe 18, and then transmitted to the main control system or other equipment through these ports.

[0083] When the sensor needs to be replaced or maintained, the operator can release the locking rod by pressing the telescopic elastic ring 221 to easily remove or replace the sensor unit.

[0084] Through the above working principle and process, the detection device can reduce the vibration and impact caused by the skip during movement in a harsh mine environment, and reduce the serious impact on the stability and reliability of the sensor.
