Description

Technical Field

[0001] The utility model relates to the technical field of overhead crane shell breaker machines, in particular to a copper sleeve lubricating device for a base of an overhead crane shell breaker machine. Background Art

[0002] As the most important auxiliary equipment for aluminum electrolysis operation, the overhead crane is used to break the crust of the insulation material around the anode carbon block in the electrolytic cell during the electrolysis operation. Only after the crust is broken can the anode be replaced and the residue cleaned. The performance of the overhead crane shelling machine will directly affect the work efficiency and safety of the electrolysis operation.

[0003] For the platform-mounted overhead crane shell breaker installed in some large-scale and efficient aluminum electrolytic cells, due to the large size of the aluminum electrolytic cells and the large number of anode replacement operations, the anode replacement and shelling operations are frequent during the operation of the overhead crane. Therefore, the rotation between the base of the overhead crane shell breaker and the copper sleeve is relatively frequent, resulting in frequent friction between the base of the overhead crane shell breaker and the copper sleeve, increased wear and consumption of the copper sleeve, and high replacement frequency and labor intensity of the copper sleeve. Therefore, the normal production and use of the overhead crane shell breaker will be delayed, and the workload and maintenance costs will be increased. Utility Model Content

The second extrusion slope is sealingly and extrusion-slidingly arranged with the first extrusion slope.

[0008] As a further preferred embodiment of the present technical solution, guide blocks are symmetrically fixedly installed on both sides of the first piston, and a guide groove for limiting the first piston is opened at the position of the guide block inside the oil storage tank, and when the guide block moves to the end of the guide groove, the second piston will just cancel the blockage of the perforation.

When the lubricating oil is sprayed out through the oil outlet hole, the force of the lubricating oil squeezing the first piston is reduced. Therefore, the second piston will be pulled downward by the return spring, and the second piston will squeeze the lubricating oil at the two ends of the oil inlet chamber, thereby further increasing the extrusion distance of the lubricating oil. The flow speed of the lubricating oil between the base of the overhead crane shell breaker and the copper sleeve can be accelerated, thereby improving the lubrication efficiency.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figures 1 to 4As shown, in the present embodiment, a copper sleeve lubrication device for a crane shell breaker base comprises a copper sleeve 1 and a crane shell breaker base 2, wherein the crane shell breaker base 2 is sleeved on the outside of the copper sleeve 1, an oil storage bin 3 is integrally fixedly installed in the middle of the crane shell breaker base 2, an oil inlet chamber 4 for lubricating oil is provided at the position where the crane shell breaker base 2 is connected to the oil storage bin 3, oil outlet holes 5 are provided on the inner wall of the crane shell breaker base 2 at positions corresponding to both ends of the oil inlet chamber 4, the oil outlet holes 5 are inclined, a threaded hole 6 is provided on the top of the oil storage bin 3, a refueling nozzle 7 is installed on the internal thread of the threaded hole 6, and the threaded hole 6 is connected to the inside of the oil inlet chamber 4.

[0022] like Figures 1 to 4 As shown, an oil pipe 8 is fixedly installed at the oil inlet end of the oil filling nozzle 7, and one end of the oil pipe 8 away from the oil filling nozzle 7 is connected to a lubricating oil tank 9, and an oil pump 10 is installed in the middle of the oil pipe 8.

[0023] The No. 3 lithium-based grease lubricating oil in the lubricating oil tank 9 is intermittently transported to the oil inlet chamber 4 inside the oil storage bin 3 through the oil pump 10 through the oil pipe 8, and sprayed out through the oil outlet hole 5. The lubricating oil is used to lubricate the copper sleeve 1 and the overhead crane shell breaker base 2, thereby increasing the service life of the copper sleeve 1 and reducing the replacement frequency of the copper sleeve 1.

[0024] like Figures 1 to 4 As shown, a first piston 11 is symmetrically and sealingly installed inside the oil storage bin 3 for sliding and sealing. A first extrusion slope 12 is provided at one top corner of the first piston 11, and a through hole 13 is provided in the middle of the first piston 11. A second piston 14 is sealingly installed up and down in the oil storage bin 3 at a position corresponding to one end of the first piston 11. The second piston 14 sealingly slides in the space between the inner cavity of the oil storage bin 3 and the first piston 11, and a second extrusion slope 15 is provided at a corner of the bottom end of the second piston 14 corresponding to the position of the first extrusion slope 12. The second extrusion slope 15 and the first extrusion slope 12 are sealingly, extrudingly and slidingly arranged.

[0025] When the No. 3 lithium-based grease lubricating oil in the lubricating oil tank 9 is intermittently transported to the oil inlet chamber 4 inside the oil storage bin 3 through the oil delivery pipe 8 by the oil pump 10, the lubricating oil will squeeze the first piston 11, driving the first piston 11 to slide inside the oil storage bin 3. The lubricating oil pressure between the two first pistons 11 will be relatively increased due to the obstruction of the first piston 11. When the lubricating oil with greater pressure flows into the two ends of the oil inlet chamber 4 from the perforation 13, a certain kinetic energy will be generated, and it will be sprayed out through the oil outlet hole 5, which increases the extrusion distance of the lubricating oil, can speed up the flow speed of the lubricating oil between the overhead crane shell breaker base 2 and the copper sleeve 1, and improve the lubrication efficiency.

[0026] like Figures 1 to 4As shown, guide blocks 16 are symmetrically fixedly installed on both sides of the first piston 11, and a guide groove 17 for limiting the first piston 11 is opened at the position corresponding to the guide block 16 inside the oil storage tank 3. When the guide block 16 moves to the end of the guide groove 17, the second piston 14 will just cancel the blockage of the through hole 13.

[0027] The movement of the first piston 11 can be limited by the relative sliding of the guide block 16 and the guide groove 17 .

[0028] like Figures 1 to 4 As shown, a slide rod 18 is fixedly installed on the top of the second piston 14, and a slide hole 19 is opened at the top of the oil storage tank 3 corresponding to the position of the slide rod 18. The slide rod 18 and the slide hole 19 are sealed and slidably arranged through a sealing component. A return spring 20 is sleeved on the outer side of the top of the slide rod 18, one end of the return spring 20 is fixedly connected to the top of the slide rod 18, and the other end of the return spring 20 is fixedly connected to the top surface of the oil storage tank 3.

[0029] When the first piston 11 moves, it will drive the second piston 14 to move upward, and the return spring 20 will be in a stretched state. When the lubricating oil is sprayed out through the oil outlet hole 5, the force of the lubricating oil squeezing the first piston 11 is reduced. Therefore, the second piston 14 will be pulled by the return spring 20 to drive the second piston 14 to move downward. On the one hand, the position of the first piston 11 is reset, and on the other hand, the second piston 14 will squeeze the lubricating oil at both ends of the oil inlet chamber 4, further increasing the extrusion distance of the lubricating oil, which can speed up the flow rate of the lubricating oil between the overhead crane shell breaker base 2 and the copper sleeve 1, and improve the lubrication efficiency.

[0030] like Figures 1 to 4 As shown, the interior of the lubricating oil tank 9 is filled with No. 3 lithium-based grease lubricating oil.

[0031] The utility model provides a copper sleeve lubricating device for the base of a crane shell breaker, and the specific working principle is as follows:

[0032] When the device is in use, the No. 3 lithium-based grease lubricating oil in the lubricating oil tank 9 is intermittently transported to the oil inlet chamber 4 inside the oil storage bin 3 through the oil pump 10 through the oil delivery pipe 8, and the lubricating oil will squeeze the first piston 11, driving the first piston 11 to slide inside the oil storage bin 3. The lubricating oil pressure between the two first pistons 11 will increase relatively due to the obstruction of the first piston 11. When the first piston 11 moves, the first extrusion slope 12 of the first piston 11 will squeeze the second extrusion slope 15 of the second piston 14, which will drive the second piston 14 to move upward. After the second piston 14 moves a certain distance, the blocking of the perforation 13 is cancelled, and the lubricating oil with relatively high pressure will flow into the two ends of the oil inlet chamber 4 through the perforation 13, and be sprayed out through the oil outlet hole 5. The lubricating oil is used to lubricate the space between the copper sleeve 1 and the overhead crane shell breaker base 2, thereby improving the lubrication effect. The service life of the copper sleeve 1 reduces the replacement frequency of the copper sleeve 1. At the same time, when the lubricating oil with high pressure flows into the two ends of the oil inlet chamber 4 from the perforation 13, a certain kinetic energy will be generated, and it will be sprayed out through the oil outlet hole 5, which increases the extrusion distance of the lubricating oil. At the same time, when the second piston 14 moves up, the return spring 20 is in an elongated state. When the lubricating oil is sprayed out through the oil outlet hole 5, the force of the lubricating oil squeezing the first piston 11 is reduced. Therefore, the second piston 14 will be pulled by the return spring 20 to drive the second piston 14 to move down. On the one hand, the position of the first piston 11 is reset, and on the other hand, the second piston 14 will squeeze the lubricating oil at both ends of the oil inlet chamber 4, further increasing the extrusion distance of the lubricating oil, which can accelerate the flow speed of the lubricating oil between the overhead crane shell breaker base 2 and the copper sleeve 1, and improve the lubrication efficiency.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
