Description

Technical Field

[0002] The mining industry is an important raw material industry and the main way to obtain existing energy. During the coal mining process, when the coal mine is a vertical shaft, in order to facilitate the lifting and transportation of coal or tools at the bottom of the mine, a wire rope winding and lifting device is usually used to lift the coal or tools. Wire ropes are generally made of steel wire ropes, which are generally composed of multiple steel strands, strands, rope cores, etc. When the wire rope is stretched, bent and twisted, the steel strands and strands have friction and wear on each other. Secondly, water vapor, mineral powder, etc. in the working environment will also cause wear and corrosion of the wire rope. Therefore, in order to improve the service life and safety of the wire rope, the wire rope is generally cleaned and lubricated regularly.

[0003] However, the traditional oiling and lubrication of wire ropes mostly adopts manual oiling, but it is extremely inconvenient to clean the old oil and impurities on the surface and inside of the wire rope during manual oiling. Secondly, the old oil cannot be cleaned out, resulting in the inability of new oil to enter.

[0015] The present invention has at least the following beneficial effects:

[0016] 1. The present invention sets a moving mechanism, a winding mechanism, etc., and when the mining bucket is loaded with goods, the second motor is electrically controlled to work, and the second motor drives the shaft to rotate. When the shaft rotates, the wire rope can be wound up, and then the mining bucket is lifted out of the mine; when the steel wire rope lifts the mining bucket out of the ground, the mining bucket is moved to a side away from the mine entrance through the action of the moving mechanism, and then the second motor is electrically controlled to work, and the second motor drives the shaft to rotate in the opposite direction to loosen the wire rope, and the mining bucket is placed on the ground, which is convenient for workers to unload the minerals inside the mining bucket.

[0017] 2. The present invention provides an upper sealing mechanism, a cleaning mechanism, and a lower sealing mechanism. After the three seal the steel wire rope to be cleaned and oiled, a cleaning liquid is injected into the cleaning box through the feed port. After the cleaning box is filled with the cleaning liquid, the ultrasonic generator is started to work, and the spiral sealing strip of the lower sealing mechanism is finally driven to rotate by the third motor. The rotating spiral sealing strip separates the steel strands of the steel wire rope from each other. At this time, by comparing the ultrasonic signal received by the ultrasonic receiving device, it is determined that the rotating spiral sealing strip separates the steel strands of the steel wire rope to a predetermined size, and then the third motor stops rotating and locks, ensuring that the spiral sealing strip keeps the steel strands of the steel wire rope in a separated position, and the rope core is also in an exposed position, so as to prepare for the ultrasonic generator to clean and oil the steel strands and rope core of the steel wire rope. Through the mutual cooperation between the above mechanisms, it can be ensured that the steel strands of the steel wire rope to be cleaned and oiled are separated from each other, and the rope core inside the steel wire rope is exposed, thereby improving the cleaning effect of each steel strand and rope core of the steel wire rope, and also improving the subsequent oiling and lubricating effect of each steel strand and rope core of the steel wire rope.

[0018] 3. The present invention sets an upper sealing mechanism, a cleaning mechanism and a lower sealing mechanism, and finally drives the spiral sealing strip of the lower sealing mechanism to rotate through the third motor. After the rotating spiral sealing strip separates the steel strands of the wire rope from each other to a predetermined degree, the ultrasonic wave generated by the ultrasonic generating device can deeply clean the steel strands of the wire rope immersed in the cleaning box, and deeply clean the exposed rope core, and can thoroughly clean the old oil inside the steel strands and the rope core; after the cleaning is completed, the fifth solenoid valve is closed and the fourth solenoid valve is opened through the controller, and the waste liquid that has cleaned the wire rope in the cleaning box enters the waste liquid recovery system through the discharge three-way pipe; through the cooperation between the above-mentioned mechanisms, after the steel strands of the wire rope are separated and the internal rope core is exposed, the inside and outside of the wire rope and the rope core can be better deeply cleaned, thereby improving the overall cleaning effect of the wire rope.

[0019] 4. The present invention sets an upper sealing mechanism, a cleaning mechanism and a lower sealing mechanism. After the cleaning of the steel wire rope is completed, the steel strands of the steel wire rope are still in a separated position, and the rope core is still in an exposed state. The second solenoid valve is closed by the controller, and the third solenoid valve is opened to allow the lubricating oil in the oil filling system to enter the cleaning box. The sound wave generating device continues to work and emits ultrasonic waves. The ultrasonic waves reduce the viscosity of the lubricating oil, so that the lubricating oil is better dispersed into the steel strands and the rope core, so that the steel strands and the rope core are fully infiltrated with the lubricating oil. After the oil filling and lubrication of the steel wire rope is completed, the third motor is started and reversed, and finally drives the spiral sealing strip of the lower sealing mechanism to rotate. The rotating spiral sealing strip causes the steel strands of the steel wire rope to close together and restore to an initial state. Through the cooperation between the above-mentioned mechanisms, the steel strands and the rope core can be fully infiltrated with the lubricating oil, which significantly improves the lubrication effect of the steel wire rope.

The lower sealing mechanism 7 is driven to rotate by a transmission mechanism 8. The transmission mechanism 8 includes a third motor and a driving gear. The third motor drives the driven gear on the lower sealing mechanism 7 to rotate through the driving gear, thereby enabling the lower sealing mechanism 7 to rotate relative to the cleaning mechanism 6; the upper airbag 504 and the lower airbag 506 on the lower sealing mechanism 7 are connected to the external inflation device through the sixth solenoid valve, and the upper airbag 504 and the lower airbag 506 on the lower sealing mechanism 7 can be controlled by the controller and the sixth solenoid valve, so that the lower sealing mechanism 7 has different functions and effects relative to the upper sealing mechanism 5. The upper outer ring 501, the upper inner ring 503 of the lower sealing mechanism 7 work together with the lower outer ring 502, the sealing pad, the spiral sealing strip 507, and the flexible pad to make the lower sealing mechanism 7 complete the sealing of the upper part of the wire rope 32, and the upper sealing mechanism 5 completes the sealing of the upper part of the wire rope 32, and the upper airbag 504 and the lower airbag 506 are further inflated through the external inflation device and the sixth solenoid valve, and the spiral sealing strip 507 of the lower sealing mechanism 7 is further clamped into the inguinal groove of the wire rope 32. At this time, the lower sealing mechanism 7 is driven by the third motor, the driving gear, and the driven gear. The sealing mechanism 7 rotates, and the spiral sealing strip 507 clamped in the strand groove of the steel wire rope 32 acts on a single steel strand of the steel wire rope 32. The rotation direction of the lower sealing mechanism 7 is opposite to the twisting direction of the multiple steel strands twisted into the steel wire rope 32. As the spiral sealing strip 507 of the lower sealing mechanism 7 is clamped and rotated, the multiple steel strands are separated. On the one hand, gaps are generated between the multiple steel strands, which is conducive to cleaning and oiling each steel strand; on the other hand, after the multiple steel strands are separated, the rope core 35 inside the steel wire rope 32 is exposed, which is convenient for cleaning and oiling the rope core 35. The spiral sealing strip 507 of the lower sealing mechanism 7 is made of polyurethane. On the one hand, the spiral sealing strip 507 made of polyurethane has a certain flexibility and can be inserted into the multiple grooves of the steel wire rope 32 after being inflated in the upper airbag 504 and the lower airbag 506 to complete the plugging of the grooves of the steel wire rope 32; on the other hand, the flexible spiral sealing strip 507 will not cause damage to the steel wire rope 32; the spiral sealing strip 507 of the lower sealing mechanism 7 is provided with reinforcing ribs inside, and the reinforcing ribs are made of alloy metal material and have strong hardness to improve the strength of the spiral sealing strip 507 of the lower sealing mechanism 7. The spiral sealing strip 507 of the lower sealing mechanism 7 reversely squeezes the steel strands so that the steel strands will not be deformed when they are separated, and the maintenance frequency of the device is reduced while ensuring the cleaning and oiling effects. The number of spiral sealing strips 507 is equal to the number of grooves of the steel wire rope 32 and the two correspond one to one, which can ensure that each groove is plugged, and drive the corresponding steel strands to move after plugging the grooves, so that the steel strands are separated. During the process of the spiral sealing strip 507 of the lower sealing mechanism 7 separating the steel strands, the external inflation device and the sixth solenoid valve gradually increase the pressure of the gas filled into the upper airbag 504 and the lower airbag 506 to ensure that the spiral sealing strip 507 can generate sufficient force to separate the steel strands.

[0042] An ultrasonic generator 606 is provided on the side wall of the left sealing portion 602 of the cleaning mechanism 6, and an ultrasonic receiver 607 is provided on the side wall of the right sealing portion 603; the ultrasonic generator 606 can generate ultrasonic waves, and in combination with the ultrasonic receiver 607, it produces multiple effects on the objects in the cleaning box 601: on the one hand, after the spiral sealing strip 507 of the lower sealing mechanism 7 separates the multiple steel strands of the wire rope 32 from each other, and after the cleaning box 601 is filled with cleaning liquid, the ultrasonic generator 606 works and emits ultrasonic waves, which are received by the ultrasonic receiver 607 through the cleaning liquid in the cleaning box 601 and the conduction of the wire rope 32, and the ultrasonic waves received by the ultrasonic receiver 607 are converted into electrical signals and transmitted In the ultrasonic processing device of the controller, the ultrasonic wave received by the ultrasonic receiving device 607 is analyzed and compared to determine the size of the multiple steel strands of the steel wire rope 32 in the cleaning box 601 separated by the spiral sealing strip 507 of the lower sealing mechanism 7. When the ultrasonic wave received by the ultrasonic receiving device 607 is analyzed and compared with the ultrasonic standard range, it is found that the gap between the multiple steel strands is small, the pressure of the gas filled in the upper airbag 504 and the lower airbag 506 of the lower sealing mechanism 7 is further increased, so that the rotating spiral sealing strip 507 on the lower sealing mechanism 7 further compresses and drives the multiple steel strands to move, so that the steel strands are separated by a larger gap, which can better clean and oil the steel strands and the internal rope core 35. The above-mentioned standard range of ultrasonic waves refers to the ultrasonic signal range received by the ultrasonic receiving device 607 when the expected cleaning effect of the steel strands and the rope core 35 of the steel wire rope is achieved through repeated experiments during the experiment using this device. On the other hand, after the spiral sealing strip 507 rotating on the lower sealing mechanism 7 separates the steel strands and exposes the rope core 35, and after the cleaning box 601 is filled with cleaning liquid, the ultrasonic generating device 606 works and emits ultrasonic waves to better clean the steel strands and rope core 35 of the steel wire rope 32, thereby improving the cleaning effect of both; thirdly, after the cleaning is completed, after the cleaning box 601 is filled with lubricating oil, the ultrasonic generating device 606 works and emits ultrasonic waves, and the ultrasonic waves reduce the viscosity of the lubricating oil, so that the lubricating oil is better dispersed into the steel strands and rope core 35, thereby improving the wetting effect of the lubricating oil.

[0043] When using the device to clean and oil the wire rope 32, first open the upper sealing mechanism 5, the cleaning mechanism 6, and the lower sealing mechanism 7, so that the three clamp the wire rope 32 to be cleaned, and then the wire rope 32 passes through the inner cavity of the cleaning box 601 and the two ends are connected to the upper sealing mechanism 5 and the lower sealing mechanism 7 respectively; fix the lower sealing mechanism 7, the cleaning mechanism 6, and the upper sealing mechanism 5 respectively, and then fix the upper sealing mechanism 5 to the shaft sleeve 47 through the fixing ears; adjust the position of the spiral sealing strip 507 on the upper sealing mechanism 5 so that it corresponds to the inguinal groove of the wire rope 32 , the upper airbag 504 and the lower airbag 506 of the upper sealing mechanism 5 are inflated through the external inflation device and the first electromagnetic valve, and the spiral sealing strip 507 of the upper sealing mechanism 5 is further clamped into the crotch of the steel wire rope 32, so that the upper sealing mechanism 5 completes the sealing of the upper part of the steel wire rope 32; similarly, the upper airbag 504 and the lower airbag 506 of the lower sealing mechanism 7 are inflated through the external inflation device and the sixth electromagnetic valve, and the spiral sealing strip 507 of the lower sealing mechanism 7 is further clamped into the crotch of the steel wire rope 32, so that the lower sealing mechanism 7 completes the sealing of the lower part of the steel wire rope 32 After the upper sealing mechanism 5, the cleaning mechanism 6, and the lower sealing mechanism 7 jointly complete the sealing of the portion of the steel wire rope 32 to be cleaned, the cleaning liquid is injected into the cleaning box 601 through the feed port 604. After the cleaning box 601 is filled with the cleaning liquid, the ultrasonic generating device 606 is started to work, and at the same time, the spiral sealing strip 507 of the lower sealing mechanism 7 is finally driven to rotate by the third motor. The rotating spiral sealing strip 507 separates the steel strands of the steel wire rope 32 from each other; at this time, by comparing the ultrasonic signal received by the ultrasonic receiving device 607, it is determined that the rotating spiral sealing strip 50 7 After the steel strands of the steel wire rope 32 are separated to a predetermined size, the third motor stops rotating and locks, ensuring that the spiral sealing strip 507 keeps the steel strands of the steel wire rope 32 in a separated position, and the rope core 35 is also in an exposed position; at this time, the ultrasonic wave emitted by the continuously working ultrasonic generator 606 cooperates with the cleaning liquid to clean the steel strands and the rope core 35 of the steel wire rope; after the specified cleaning time is completed, the fifth solenoid valve is closed by the controller, and the fourth solenoid valve is opened, and the waste liquid in the cleaning box 601 that has cleaned the steel wire rope 32 enters the waste liquid recovery system through the discharge three-way pipe.

[0044] After the cleaning of the steel wire rope 32 is completed, when the steel wire rope 32 needs to be oiled for maintenance, the second solenoid valve is closed through the controller, and the third solenoid valve is opened to allow the lubricating oil in the oiling system to enter the cleaning box 601, and the sound wave generating device 606 continues to work and emits ultrasonic waves. The ultrasonic waves reduce the viscosity of the lubricating oil and allow the lubricating oil to be better dispersed into the steel strands and the rope core 35, so that the steel strands and the rope core 35 are fully infiltrated with the lubricating oil. After the lubrication of the steel wire rope 32 is completed, the third motor starts and reverses, and finally drives the spiral sealing strip 507 of the lower sealing mechanism 7 to rotate. The rotating spiral sealing strip 507 makes the steel strands of the steel wire rope 32 close together and restore to the initial state; then the controller controls the external inflation device and the first solenoid valve to deflate the upper airbag 504 and the lower airbag 506 of the upper sealing mechanism 5, so that the spiral sealing strip 507 of the upper sealing mechanism 5 leaves the inguinal groove of the steel wire rope 32 and creates a certain gap with the steel wire rope, which does not affect the upward movement of the steel wire rope 32; similarly, the upper airbag 504 and the lower airbag 506 of the lower sealing mechanism 7 are deflated through the external inflation device and the sixth solenoid valve, so that the spiral sealing strip 507 of the lower sealing mechanism 7 The wire rope 32 leaves the groove of the wire rope 32 and forms a certain gap with the wire rope, which does not affect the upward movement of the wire rope 32; the winding mechanism 3 winds up the wire rope 32 after cleaning and oiling. In the process of the wire rope 32 being wound up and moving upward, on the one hand, the outer surface of the wire rope 32 is fully wrapped by the lubricating oil in the cleaning box 601, and on the other hand, the winding mechanism 3 drives the sleeve 47 to rotate through the driving mechanism 4, and the sleeve 47 drives the upper sealing mechanism 5 to rotate. Since the spiral sealing strip 507 of the upper sealing mechanism 5 leaves the groove of the wire rope 32 and forms a certain gap with the wire rope, the excess lubricating oil on the wire rope 32 can be scraped off and retained in the cleaning box 601, preventing the wire rope 32 from being wasted due to too much lubricating oil, and being contaminated by debris. After cleaning and oiling, a section of the wire rope is reserved to be clamped by the upper sealing mechanism 5 when cleaning the subsequent wire rope, and the rest is all wound up by the winding mechanism 3; when the winding is completed, a new section of the wire rope to be cleaned enters the cleaning box 601. At this time, the controller closes the fourth solenoid valve and opens the fifth solenoid valve, and the remaining lubricating oil in the cleaning box 601 is sucked back into the lubricating oil recovery system by the negative pressure, and can be reused after being filtered by the lubricating oil recovery system. After the lubricating oil in the cleaning box 601 is completely recovered, the steel wire rope 32 newly entering the cleaning box 601 is cleaned and oiled according to the above method for maintenance.
