Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical lubrication, in particular to a component lubrication device for a crawler excavator. Background Art

[0002] Crawler excavators are earth-moving machines that use buckets to dig materials above or below the bearing surface and load them into transport vehicles or unload them to stockpiles. Crawler excavators have a large number of rotating parts, which require lubrication and maintenance with a grease gun after long-term use.

[0003] The existing grease gun separates the grease gun head from the gun barrel, immerses the grease gun head into the grease barrel to a depth of about 30 mm, pulls the barrel handle, and sucks the grease into the barrel tube. However, grease has a certain viscosity. After the grease gun is inserted into the grease barrel, a large amount of grease will adhere to the outside of the gun barrel. In the prior art, the grease is often wiped off directly with a wiping cloth, resulting in a large amount of grease waste. A crawler excavator component lubrication device is now proposed to solve the above problems. Utility Model Content

[0004] (1) Technical problems solved

[0005] In order to solve the problems raised in the above-mentioned background technology, the utility model provides a crawler excavator component lubricating device, which can rotate the movable ring to move to the side away from the spring, so that the air pressure on the top of the limit block is reduced, and the elastic force of the spring can pull the limit block upward, so that the limit block is not engaged with the left end slot, and the storage cylinder is pulled out to the left, so that the limit ring moves to the right side of the limit slot. At this time, the slot at the right end is located directly below the limit block, and the movable ring is rotated in the opposite direction to increase the air pressure on the top side of the limit block, so that the limit block is engaged with the slot at the right end, and the extended part of the storage cylinder is inserted into the butter barrel for extraction, and the movable ring is rotated, and the sealing cover is pressed and the storage cylinder is pushed toward the inside of the limit cylinder. The butter attached to the outside of the storage cylinder can be scraped off to the inside of the sealing cover through the limit cylinder, which has the advantage of high butter utilization rate.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figures 1 to 5As shown, the utility model provides a crawler excavator component lubricating device, including a limiting cylinder 1, a sealing cover 2 and a piston rod 3. The interior of the limiting cylinder 1 is movably connected to a storage cylinder 4. A limiting groove 6 is provided on the side of the storage cylinder 4 close to the sealing cover 2. The limiting groove 6 is movably engaged with a limiting ring 5 on the side close to the sealing cover 2. Two grooves 10 are provided in an annular shape in the middle of the storage cylinder 4. A limiting block 7 is movably engaged with an annular shape at equal angles in the inner side of the left end groove 10. A spring 8 is fixedly connected to the top side of the limiting block 7. A movable ring 9 is threadedly connected to the middle part of the limiting cylinder 1. An air hole 12 is provided in an annular shape at equal angles on the left side of the movable ring 9. A fixed sleeve 11 is fixedly connected to the side of the limiting cylinder 1 away from the sealing cover 2. By rotating and removing the sealing cover 2 and rotating the movable ring 9, the movable ring 9 moves to the side away from the spring 8, so that the air pressure on the top of the limiting block 7 is reduced. The limit block 7 can be pulled upward by the elastic force of the spring 8, so that the limit block 7 is not engaged with the left end slot 10, and the storage cylinder 4 is pulled out to the left, so that the limit ring 5 moves to the right side of the limit slot 6. At this time, the slot 10 at the right end is located just below the limit block 7. By rotating the movable ring 9 in the opposite direction, the air pressure on the top side of the limit block 7 is increased, so that the limit block 7 is engaged with the slot 10 at the right end. By inserting the extended part of the storage cylinder 4 into the butter barrel for extraction, by rotating the movable ring 9, the limit block 7 is no longer engaged with the right end slot 10, and by abutting the sealing cover 2 and pushing the storage cylinder 4 toward the inside of the limit cylinder 1, the limit ring 5 is moved to the left side of the limit slot 6. The butter attached to the outside of the storage cylinder 4 can be scraped off to the inside of the sealing cover 2 through the limit cylinder 1, so that the device can clean and utilize the attached butter, so that the butter utilization rate of the device is high.

[0025] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5As shown, the left side of the limiting cylinder 1 is threadedly connected to the sealing cover 2, the middle part of the right side of the limiting cylinder 1 is movably connected to the piston rod 3, the inner side of the storage cylinder 4 is movably connected to the piston rod 3, the outer ring of the limiting ring 5 is fixedly connected to the limiting cylinder 1, the spacing between the two card grooves 10 is equal to the length of the limiting groove 6, the outer end of the limiting block 7 is movably connected to the limiting cylinder 1, the other side of the spring 8 is fixedly connected to the limiting cylinder 1, the other side of the air hole 12 is located at the upper end of the spring 8, the left side of the movable ring 9 is movably connected to the limiting cylinder 1, the outer sides of the movable ring 9 and the fixed sleeve 11 are both provided with rubber strips at equal angles in annular shapes, the left side of the storage cylinder 4 is movably connected to the sealing cover 2, the limiting cylinder 1 and the storage cylinder 4 are made of explosion-proof materials; value It should be noted that the limiting cylinder 1, sealing cover 2 and piston rod 3 are existing technologies. By pulling and pulling the piston rod 3, butter can be sucked in and pushed out, and by squeezing out through the nozzle of the sealing cover 2, the mechanical parts can be lubricated and maintained. I will not go into details here. By inserting the protruding part of the storage cylinder 4 into the butter barrel and engaging the slot 10 at the right end with the limiting block 7, the storage cylinder 4 can be limited. By pulling the piston rod 3, the butter can enter the interior of the storage cylinder 4. By putting the storage cylinder 4 into the limiting cylinder 1 and engaging the slot 10 at the left end with the limiting block 7, the butter can be squeezed out by pushing the piston rod 3. The friction force can be increased by the rubber strip, which facilitates the operation of the handheld device.

[0026] The working principle and use process of this utility model:

[0027] The locking ring 9 is rotated to move the locking ring 9 away from the spring 8, so that the air pressure on the top of the limit block 7 is reduced. The elastic force of the spring 8 can pull the limit block 7 upward so that the limit block 7 is not engaged with the left end slot 10, and the storage cylinder 4 is withdrawn to the left, so that the limit ring 5 moves to the right side of the limit slot 6. At this time, the right end slot 10 is located directly below the limit ring 7. By rotating the movable ring 9 in the opposite direction, the air pressure on the top side of the limit block 7 is increased, so that the limit block 7 is engaged with the right end slot 10. The extended part of the storage cylinder 4 is inserted into the butter barrel for extraction. By rotating the movable ring 9, the limit block 7 is not engaged with the right end slot 10. By pressing the sealing cover 2 and pushing the storage cylinder 4 toward the inside of the limit cylinder 1, the limit ring 5 is moved to the left side of the limit slot 6. The butter attached to the outside of the storage cylinder 4 can be scraped off to the inside of the sealing cover 2 through the limit cylinder 1. The operation is completed.
