Description

Technical Field

[0001] The invention relates to the field of wire rope hoisting support equipment, and in particular to a wire rope hoisting support roller and a use method thereof. Background Art

[0002] The wire rope winch roller supports the wire rope in the wire rope transmission and lifting systems to keep it in a stable position and shape, avoiding excessive overhang or shaking. At the same time, it converts the sliding friction between the wire rope and the roller into rolling friction to reduce operating resistance and energy loss. It can also protect the wire rope from wear and collision and ensure its smooth operation, thereby improving the safety, efficiency and reliability of the system. It is widely used in mining transportation, lifting equipment, ship unloaders and other scenarios.

[0003] At present, the steel cable hoisting roller relies on manual regular grease filling or a simple automatic oil dripping device, which cannot dynamically adjust the lubrication amount according to the actual working condition of the bearing. For example, the grease in the underground roller of the coal mine is often hardened due to the intrusion of coal dust, and the manual maintenance cycle is difficult to match the actual wear rate, which can easily cause the bearing to stagnate or even lock. In addition, most rollers use rubber seals. In harsh environments such as dust and water, the seals are prone to aging and deformation, and the gaps will also expand due to impact vibration, causing coal dust and water to intrude into the bearing, accelerating the corrosion of metal parts; the lubrication system of existing rollers often requires the removal of the end cover or the overall disassembly to replenish grease, and the replacement of seals is cumbersome, especially in high-altitude or heavy-loaded equipment. The operation risk is high and time-consuming. The end cover cannot be removed on the fully rubberized roller, which makes it difficult to replenish the lubricating medium later; in addition, traditional rollers cannot automatically trigger the lubrication compensation mechanism when stuck, which can easily lead to increased sliding friction between the steel cable and the roller, accelerating the wear of both. Summary of the invention

[0004] The purpose of the present invention is to provide a winch support roller for a steel cable and a method of using the same in order to solve the above problems. When the bearing is stuck, the centrifugal force of the shaft rotation drives the plug to move outward, automatically opens the lubrication channel, and delivers the grease in the storage chamber to the bearing without manual intervention, thus solving the problem of untimely lubrication of traditional rollers. It has both automatic oil replenishment in case of faults and manual wrench operation for oil replenishment, covering all scenario needs, without the need for an additional power source, relying on its own rotational kinetic energy, and is suitable for harsh environments without power supply or explosion-proof environments.

A movable component is provided outside the fixing ring, and a consumable bottle extending into the shaft end tube is detachably provided on the outer end of the movable component.

[0011] Preferably, the movable component includes a movable ring slidably mounted on the outside of the core rod, a storage cavity connected to the inner hole is formed between the movable ring and the fixed ring, the storage cavity is used to store grease, the outer end of the core rod is provided with an injection hole connected to the consumable bottle, the core rod at the inner end of the injection hole is connected to a one-way hole extending into the storage cavity, and the outer port of the one-way hole is provided with a one-way valve.

[0013] Preferably, a bearing supporting the rotation of the rubber-coated roller is fixed on the outer side of the boss, an inner sealing ring is arranged between the bearing and the end face of the shaft rod, an inner sealing ring is fixed on the outer side of the synchronous ring, and an outer sealing ring is arranged on the inner side of the rubber-coated roller, and the inner sealing ring and the outer sealing ring cooperate to form a cross-engaging labyrinth sealing ring.

[0014] The method for using the hoisting support roller for the steel cable comprises the following steps: a. When in use, the two sets of shaft end tubes are respectively set on the rotating table that needs to support the movement of the steel cable winch, and the shaft end tubes are installed and supported by the bearing seat. During use, the rubber-coated roller serves as the steel cable support moving structure. Under the support of the bearing, the rubber-coated roller rotates synchronously with the movement of the steel cable. When the bearing is poorly lubricated due to lack of lubricating medium, agglomeration, and hardening, the steel cable drives the rubber-coated roller to rotate, and at the same time drives the stuck shaft and its external accessories to rotate synchronously; b. The shaft rotates rapidly along with the rubber-coated roller. The plug in the receiving groove on the inner side of the boss is subjected to centrifugal force. The plug and the support rod overcome the pressure of the spring and move outward. The plug's blocking effect on the inner hole is released. At this time, the lubricating grease in the storage chamber is also injected into the receiving groove along the inner hole under the centrifugal force, and is injected into the inner through hole position in the sliding groove along the outer hole and the guide hole; c. When the plug, the support rod, the pressure ring and the transmission rod slide and swing outward, the sliding piece of the synchronous ring extends into the sliding groove of the boss, and the sliding piece is located in one side of the sliding groove. When the boss rotates and the synchronous ring is still in a stationary state, the sliding piece will slide to the other side of the sliding groove due to inertia. In this process, the synchronous ring and the end cover will rotate relative to each other, and the transmission rod on the outer side of the pressure ring extends into the transmission groove of the synchronous ring along the guide groove. The transmission groove is an inclined groove, so it can cooperate to promote the plug to expand and slide outward. When the plug is separated from the inner hole and does not contact the outer hole, the synchronous ring rotates to the center of the sliding groove. That is, at this time, the outer through hole of the sliding piece is in the position of connecting the inner through hole of the boss, thereby realizing the process of infusing lubricating grease into the bearing area along the accommodating groove; d. When the lubricating grease in the bearing area is replenished to a good lubrication level, the stuck state of the shaft disappears, and the shaft cannot rotate synchronously with the rubber-coated roller, that is, the rotation speed of the shaft gradually decreases, so that the spring in the compressed state pushes the pressure ring, the transmission rod, the support rod and the plug to reset, and the plug is used to close the inner hole again, and the transmission rod extending into the inclined groove structure is used to support the synchronous ring and the sliding plate to rotate and reset, completing the plug to close the inner hole, and staggering the outer through hole of the sliding plate with the inner through hole of the boss to achieve the closing action of the outer through hole, so as to achieve secondary closure of the lubricating grease filling channel and complete the automatic replenishment of lubricating grease when the rotation is stuck; e. When manual grease replenishment is required, the maintenance personnel use a wrench to clamp on the clamping groove of the shaft end tube, keep the shaft end tube in a stationary state, and then rotate the synchronizer ring, using the transmission groove of the inclined groove structure on the inner wall of the synchronizer ring to follow the rotation of the synchronizer ring through the transmission groove to drive the inner transmission rod to expand outward, and the transmission rod pulls the pressure ring, the support rod and the plug outward along the guide groove, and at the same time compresses the plug to separate from the inner hole. At this time, the consumable bottle is pulled laterally outward, and the consumable bottle is used to drive the movable assembly to move outward as a whole. The movable ring is close to the fixed ring, and the space in the storage chamber is reduced, thereby forcing the lubricating grease in the storage chamber to be filled into the accommodating groove along the inner hole in the open state, and the lubricating grease is guided by the inner through hole opened by rotation to be discharged to the bearing area along the guide hole, completing the manual lubrication work; f. When the consumable bottle needs to be replaced, pull the used consumable bottle out of the shaft end tube and unscrew the consumable bottle from the mounting ring. Then fix the consumable bottle filled with grease to the inside of the mounting ring, push the consumable bottle to slide toward the fixing ring, and use the piston disc to extend into the consumable bottle. During the pushing process, the grease in the consumable bottle is pushed into the storage cavity along the injection hole and the one-way hole, and a negative pressure is formed through the continuously expanding space in the storage cavity, which assists in the rapid injection of grease, thereby completing the rapid replenishment of the grease consumable in the storage cavity.

[0015] The beneficial effects are as follows: 1. The present invention sets an automatic lubricating medium replenishment function, utilizes the centrifugal effect generated by the rotation of the shaft back pack rubber roller when the bearing is stuck, drives the plug to overcome the spring pressure and move outward, automatically opens the lubrication channel, and delivers the grease in the storage chamber to the bearing area, and can realize automatic oil replenishment on demand without manual intervention, thereby solving the problem that traditional rollers rely on fixed periodic maintenance and untimely lubrication; 2. It has both the function of automatic oil replenishment triggered by faults and manual oil replenishment by operating the synchronizer ring with a wrench. It can meet the needs of unattended operation under harsh working conditions and the flexibility of manual maintenance. It covers the lubrication needs of all scenarios and does not require additional power sources, such as motors and hydraulic systems. Lubrication can be achieved only by relying on the rotational kinetic energy of the roller itself. It is suitable for harsh environments such as mines and ports without power supply or explosion-proof requirements. 3. The sliding sheet of the synchronizer ring and the sliding groove of the boss are designed to fit together. When the oil injection channel is opened, the inner and outer through holes are temporarily connected. When it is closed, the oil injection channel is sealed again to avoid leakage of lubricating media in the storage cavity and the accommodating groove. The labyrinth seal formed by the cross-engagement of the inner sealing retainer ring and the outer sealing retainer ring can effectively reduce bearing corrosion and loss of lubricating media. 4. Through the cooperation between the transmission groove and the transmission rod of the bevel groove structure on the end face of the synchronizer ring, the relative rotational motion between the shaft rod and the synchronizer ring is converted into the axial displacement of the plug, ensuring the automatic matching of the automatic lubrication and reset process, avoiding the inaccurate opening and closing of the traditional roller oil injection channel, and the complexity and failure rate of relying on external circuit control components; 5. The lubricating medium is transported through a closed path from the inner hole, the receiving groove, the outer hole, and the guide hole to the inner through hole, and directly reaches the bearing lubrication point, reducing the grease waste and pollution risk caused by the open oiling of traditional rollers.

[0022] The method for using the winch support roller for the steel cable comprises the following steps: a. When in use, the two sets of shaft end tubes 7 are respectively arranged on the rotating table that needs to support the movement of the steel cable winch, and the shaft end tubes 7 are installed and supported by the bearing seat. During use, the rubber-coated roller 2 is used as a steel cable support moving structure. Under the support of the bearing 8, the rubber-coated roller 2 rotates synchronously with the movement of the steel cable. When the bearing 8 is poorly lubricated due to lack of lubricating medium, agglomeration, and hardening, the steel cable drives the rubber-coated roller 2 to rotate, and at the same time drives the stuck shaft 1 and its external accessories to rotate synchronously; b. The shaft 1 rotates rapidly following the rubber-coated roller 2. The plug 107 in the receiving groove on the inner side of the boss 101 is subjected to centrifugal force. The plug 107 and the support rod 106 overcome the pressure of the spring 108a and move outward. The plug 107 is released from the blocking effect of the inner hole 103a. At this time, the lubricating grease in the storage chamber 13 is also injected into the receiving groove along the inner hole 103a under the centrifugal force, and is injected into the inner through hole 105 in the sliding groove 102 along the outer hole 103b and the guide hole 104; c. When the plug 107, the support rod 106, the pressure ring 108 and the transmission rod 109 slide and swing outward, the sliding piece 401 of the synchronizer ring 4 extends into the sliding groove 102 of the boss 101, and the sliding piece 401 is located on one side of the sliding groove 102. When the boss 101 rotates and the synchronizer ring 4 is still in a stationary state, the sliding piece 401 will slide to the other side of the sliding groove 102 due to inertia. In this process, the synchronizer ring 4 and the end cover 3 will rotate relative to each other, and the transmission rod 109 on the outside of the pressure ring 108 will rotate relative to each other. The movable rod 109 extends along the guide groove 302 into the transmission groove 403 of the synchronizer ring 4. The transmission groove 403 is an oblique groove, so it can cooperate to cause the plug 107 to expand and slide outward. When the plug 107 is separated from the inner hole 103a and does not contact the outer hole 103b, the synchronizer ring 4 rotates to the sliding piece 401 at the center of the sliding groove 102, that is, at this time, the outer through hole 402 of the sliding piece 401 is in the position of communicating with the inner through hole 105 of the boss 101, thereby realizing the process of lubricating grease being infused along the accommodating groove 103 to the bearing 8 area; d. When the lubricating grease in the bearing 8 area is replenished to a good lubrication state, the stuck state of the shaft 1 disappears, and the shaft 1 cannot rotate synchronously with the rubber-coated roller 2, that is, the rotation speed of the shaft 1 gradually decreases, so that the spring 108a in the compressed state pushes the pressure ring 108, the transmission rod 109, the support rod 106 and the plug 107 to reset, and the plug 107 is used to close the inner hole 103a again, and the transmission rod 109 extending into the inclined groove structure is used to support the synchronous ring 4 and the sliding plate 401 to rotate and reset, completing the closing action of the plug 107 on the inner hole 103a, and staggering the outer through hole 402 of the sliding plate 401 with the inner through hole 105 of the boss 101, so as to realize the closing action of the outer through hole 402, so as to realize the secondary closing of the lubricating grease filling channel, and complete the automatic replenishment of lubricating grease when the rotation is stuck; e. When manual grease replenishment is required, the maintenance personnel use a wrench to clamp on the clamping groove 702 of the shaft end tube 7, keep the shaft end tube 7 in a stationary state, and then rotate the synchronizer ring 4, using the transmission groove 403 of the inner wall oblique groove structure of the synchronizer ring 4 to follow the synchronization ring 4 through the transmission groove 403 to rotate, thereby driving the inner transmission rod 109 to expand outward, and the transmission rod 109 pulls the pressure ring 108, the support rod 106 and the plug 107 to expand outward along the guide groove 302, and at the same time compresses the plug 107 to separate from the inner hole 103a, at this time, the consumable bottle 11 is pulled laterally outward, and the consumable bottle 11 is used to drive the movable assembly 10 to move outward as a whole, and the movable ring 10a is close to the fixed ring 901, and the space in the storage chamber 13 is reduced, thereby forcing the lubricating grease in the storage chamber 13 to be filled into the accommodating groove 103 along the inner hole 103a in the open state, and the lubricating grease is guided by the inner through hole 105 opened by rotation to be discharged to the bearing 8 area along the guide hole 104, thereby completing the manual lubrication work; f. When the consumable bottle 11 needs to be replaced, the used consumable bottle 11 is pulled out of the shaft end tube 7, and the consumable bottle 11 is screwed down from the mounting ring 10b. Then, the consumable bottle 11 filled with lubricating grease is fixed to the inner side of the mounting ring 10b, and the consumable bottle 11 is pushed to slide toward the fixing ring 901. The piston plate 903 is extended into the consumable bottle 11, so that the lubricating grease in the consumable bottle 11 is input into the storage chamber 13 along the injection hole 902 and the one-way hole 904 during the pushing process, and a negative pressure effect is formed through the continuously expanding space in the storage chamber 13, which assists in the rapid injection of lubricating grease, thereby completing the rapid replenishment of the lubricating grease consumable in the storage chamber 13.

[0023] The present invention is provided with an automatic lubricating medium replenishment function, and utilizes the centrifugal effect generated by the rotation of the shaft rod 1 and the rubber roller 2 when the bearing 8 is stuck, so as to drive the plug 107 to overcome the pressure of the spring 108a and move outward, and automatically open the lubrication channel, and transport the grease in the storage chamber 13 to the bearing 8 area, so as to realize automatic oil replenishment on demand without manual intervention, and solve the problem that the traditional rollers rely on fixed periodic maintenance and untimely lubrication; It has both the function of automatic oil replenishment triggered by faults and manual oil replenishment by operating the synchronizer ring 4 with a wrench. It can meet the needs of unattended operation under harsh working conditions and the flexibility of manual maintenance. It covers the lubrication needs of all scenarios and does not require additional power sources such as motors and hydraulic systems. Lubrication can be achieved only by relying on the rotational kinetic energy of the rollers themselves. It is suitable for harsh environments such as mines and ports without power supply or explosion-proof requirements. The sliding sheet 401 of the synchronizer ring 4 and the sliding groove 102 of the boss 101 are designed to fit together, and the inner and outer through holes 402 are temporarily connected when the oil injection channel is opened, and the oil injection channel is secondary sealed when it is closed, so as to avoid leakage of the lubricating medium in the storage cavity 13 and the accommodating groove 103, and cooperate with the labyrinth seal ring formed by the cross-biting of the inner sealing retainer ring 5 and the outer sealing retainer ring 6 to effectively reduce the corrosion of the bearing 8 and the loss of the lubricating medium; Through the cooperation between the transmission groove 403 of the end face bevel structure of the synchronizer ring 4 and the transmission rod 109, the relative rotational motion between the shaft rod 1 and the synchronizer ring 4 is converted into the axial displacement of the plug 107, ensuring the automatic matching of the automatic lubrication and reset process, avoiding the inaccurate opening and closing of the traditional roller oil injection channel, and the complexity and failure rate of the reliance on external circuit control components; The lubricating medium is transported in a closed path through the inner hole 103a, the accommodating groove 103, the outer hole 103b, and the guide hole 104 to the inner through hole 105, and directly reaches the lubrication point of the bearing 8, reducing the grease waste and pollution risk caused by the open oiling of the traditional roller.

[0024] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.

10. The method for using the hoisting support roller for a steel cable according to claim 9, characterized in that: The following steps are involved: a. When in use, the two sets of shaft end tubes (7) are respectively arranged on a rotating table that needs to support the movement of the steel cable winch, and the shaft end tubes (7) are installed and supported by the bearing seat. During use, the rubber-coated roller (2) serves as a structure for supporting the moving of the steel cable. Under the support of the bearing (8), the rubber-coated roller (2) rotates synchronously with the movement of the steel cable. When the bearing (8) is poorly lubricated due to lack of lubricating medium, agglomeration, or hardening, the steel cable drives the rubber-coated roller (2) to rotate, and at the same time drives the shaft rod (1) and its external accessories in a stuck state to rotate synchronously; b. The shaft (1) rotates rapidly following the rubber-coated roller (2), and the plug (107) in the receiving groove inside the boss (101) is subjected to centrifugal force. The plug (107) and the support rod (106) overcome the pressure of the spring (108a) and move outward. The blocking effect of the plug (107) on the inner hole (103a) is released. At this time, the lubricating grease in the storage chamber (13) is also injected into the receiving groove along the inner hole (103a) under the centrifugal force, and is injected into the inner through hole (105) in the sliding groove (102) along the outer hole (103b) and the guide hole (104); c. When the plug (107), the support rod (106), the pressure ring (108), and the transmission rod (109) slide and swing outward, the sliding piece (401) of the synchronizer ring (4) extends into the sliding groove (102) of the boss (101), and the sliding piece (401) is located in the one side area of ​​the sliding groove (102). When the boss (101) rotates and the synchronizer ring (4) is still in a stationary state, the sliding piece (401) will slide to the other side of the sliding groove (102) due to inertia. In this process, the synchronizer ring (4) and the end cover (3) will rotate relative to each other, and due to the transmission rod (109) on the outside of the pressure ring (108), the sliding piece (401) will slide to the other side of the sliding groove (102). The rod (109) extends along the guide groove (302) into the transmission groove (403) of the synchronizer ring (4). The transmission groove (403) is an inclined groove, so it can cooperate to cause the plug (107) to expand and slide outward. When the plug (107) is separated from the inner hole (103a) and does not contact the outer hole (103b), the synchronizer ring (4) rotates simultaneously until the sliding plate (401) is located at the center of the sliding groove (102), that is, at this time, the outer through hole (402) of the sliding plate (401) is located at the position of the inner through hole (105) connected to the boss (101), thereby realizing the process of injecting lubricating grease into the bearing (8) area along the accommodating groove (103); d. When the lubricating grease in the bearing (8) area is replenished to a good lubrication level, the stuck state of the shaft (1) disappears, and the shaft (1) cannot rotate synchronously with the rubber-coated roller (2), that is, the rotation speed of the shaft (1) gradually decreases, so that the spring (108a) in the compressed state pushes the pressure ring (108), the transmission rod (109), the support rod (106) and the plug (107) to reset, and the plug (107) is used to close the inner hole (103a) again. , and using the transmission rod (109) extending into the inclined groove structure to support the synchronous ring (4) and the sliding plate (401) to rotate and reset, complete the closing action of the plug (107) on the inner hole (103a), and stagger the outer through hole (402) of the sliding plate (401) and the inner through hole (105) of the boss (101) to achieve the closing action of the outer through hole (402), so as to achieve secondary closure of the lubricating grease filling channel, and complete the automatic replenishment of lubricating grease when the rotation is stuck; e. When manual lubrication grease is required, the maintenance personnel use a wrench to clamp the clamping groove (702) of the shaft end tube (7), keep the shaft end tube (7) in a stationary state, and then rotate the synchronizer ring (4), using the transmission groove (403) of the inclined groove structure on the inner wall of the synchronizer ring (4) to follow the rotation of the synchronizer ring (4) through the transmission groove (403) to drive the inner transmission rod (109) to expand outwards, and the transmission rod (109) pulls the pressure ring (108), the support rod (106) and the plug (107) along the guide groove (302) to expand outwards, and at the same time compress the plug (107) to expand outwards. The head (107) is separated from the inner hole (103a), and the consumable bottle (11) is pulled laterally outward at this time, and the movable component (10) is driven to move outward as a whole by the consumable bottle (11), and the movable ring (10a) is close to the fixed ring (901), and the space in the storage chamber (13) is reduced, thereby forcing the lubricating grease in the storage chamber (13) to be filled into the accommodating groove (103) along the inner hole (103a) in the open state, and the lubricating grease is guided to be discharged along the guide hole (104) to the bearing (8) area through the inner through hole (105) that is rotated to open, thereby completing the manual lubrication work; f. When it is necessary to replace the consumable bottle (11), the used consumable bottle (11) is pulled out of the shaft end tube (7), and the consumable bottle (11) is screwed down from the mounting ring (10b). Then, the consumable bottle (11) filled with lubricating grease is fixed to the inner side of the mounting ring (10b), and the consumable bottle (11) is pushed to slide in the direction close to the fixing ring (901). The piston plate (903) is extended into the consumable bottle (11), so that during the pushing process, the lubricating grease in the consumable bottle (11) is urged to be input into the storage chamber (13) along the injection hole (902) and the one-way hole (904), and a negative pressure effect is formed through the continuously expanding space in the storage chamber (13), thereby assisting the rapid injection of the lubricating grease, and completing the rapid replenishment of the lubricating grease consumable in the storage chamber (13).
