- the tray assembly 208 is re-installed by pushing the tray assembly 208 , and the bottom 326 of the tray assembly 208 rides along the lip portion 310 of the mount assembly 206 . While sliding, the first and second longitudinal walls 304 , 306 of the mount assembly 206 guide the tray assembly 208 to reduce the occurrence of side-to-side tipping. The tray assembly 208 slides above the lip portion 310 to be installed in the mount assembly 206 , and the tray assembly 208 engages with the tab portion 324 , which acts to retain the tray assembly 208 . Since the tray assembly 208 is removably positioned inside the mount assembly 206 , the tray assembly 208 is efficiently installed and removed.

Description
- The present disclosure relates generally to construction machines. More specifically, the present disclosure relates to a lubricant collecting assembly for construction machines.
- Various construction machines, such as industrial shovels, are employed to perform several operations such as, excavation, demolition, digging, and the like. These construction machines generally include a pivotable lift arm assembled with a machine frame via a pin joint. The pin joint is lubricated at regular intervals to minimize metal-to-metal wear that would occur without such lubrication.
- In certain situations, to ensure that the pin joint is completely filled with lubricant or grease, the service person may continue to add grease until it extrudes from the periphery of the joint. Often the excess grease may fall from the pin joint and onto the ground and/or various parts of the construction machines. Such unmanaged disposal of grease is unsightly, subject to causing slippery surfaces and environmentally undesirable. It is known to install a lubricant collecting assembly within a construction machine to collect the dripping lubricant. However, the structure of these collecting assemblies make it difficult to service and clean, especially when the collecting structure is full of grease.
- Japanese patent, JP2005200970A discloses a shovel, in which a boom is connected with a frame via a pin joint. A container for collecting grease drippings is provided at the bottom of the frame. Such assembly includes the container positioned, which is difficult to access and cumbersome to install and remove for re-usage. Moreover, the container is placed at the bottom of the frame and therefore lubricant must travel a long way to be collected inside the container, which may still cause some lubricant to fall on surrounding surfaces of the machine or the ground.
- Various aspects of the present disclosure are directed to a lubricant collecting assembly for a construction machine. The construction machine has a pivotable lift arm assembled to a machine frame via a pin joint. The lubricant collecting assembly collects lubricant that drips from the pin joint. The lubricant collecting assembly includes a mount assembly and a tray assembly.
- The mount assembly is attached to the machine frame and includes a base portion, a first longitudinal wall, a second longitudinal wall, a transverse wall, and a lip portion. The base portion has a first end portion and a second end portion. The first longitudinal wall and the second longitudinal wall are both extended from the base portion. At least one of the first longitudinal wall and the second longitudinal wall has a mounting portion for attaching the mount assembly to the machine frame. The transverse wall extends from the first end portion of the base portion and is positioned between the first longitudinal wall and the second longitudinal wall. The transverse wall includes a tab portion and defines a first height. Further, the lip portion is extended from the second end portion of the base portion between the first longitudinal wall and the second longitudinal wall. The lip portion defines a height. The height of the lip portion is lesser than the height of the transverse wall.
- Further, the tray assembly is structured and arranged to be removably positioned within the mount assembly and retained by the tab portion of the transverse wall of the mount assembly. The tray assembly includes a first longitudinal side wall and a second longitudinal side wall. Both the first longitudinal side wall and the second longitudinal side wall define wing portions extended outwardly relative to the first and second longitudinal side walls.

FIG. 5 , thetray assembly 208 will now be described. Thetray assembly 208 may be removably positioned inside themount assembly 206 as is best seen inFIG. 3 . Thetray assembly 208, not unlike themount assembly 206 is a box like container structure and must be generally leak proof to suitably catch and contain dripping lubricant. Thetray assembly 208 includes a bottom 326, a first and secondlongitudinal side walls back wall 332 and afront wall 334 all generally perpendicularly extended from and joined with the bottom 326. Each of the first and secondlongitudinal side walls wing portions wing portions longitudinal side walls tray assembly 208 which aids in catching substantially all of the lubricant dripping from the pin joint 118 (FIG. 2 ). Thetray assembly 208 further includes ahandle 340 to aid a service person in expedient installation and removal of thetray assembly 208 from themount assembly 206. - In the assembled position as is best shown in
FIG. 2 , thetray assembly 208 is positioned within themount assembly 206, such that the first and secondlongitudinal side walls tray assembly 208 are substantially parallel to and respectively guided by the first and secondlongitudinal walls mount assembly 206 during assembly (as shown inFIG. 6 ). It will be understood that when thetray assembly 208 is placed inside themount assembly 206, thewing portion 336 of the firstlongitudinal side wall 328 substantially abuts theinner side 202 of theflanged portion 110 of themachine frame 102, thereby directing additional lubrication that is running down theinner side 202 of theflanged portion 110, within itself. - Further, it will be understood that the
tray assembly 208 is by design retained within themount assembly 206 during normal operation of theconstruction machine 100. This is due to thetray assembly 208 being of complimentary configuration relative to themount assembly 206 however sized slightly smaller to keep thetray assembly 208 from tipping. Moreover, thetab portion 324 of themount assembly 206 acts to retain thetray assembly 208 yet allows for thetray assembly 208 to be expediently removed by a slight pull of thehandle 340 of thetray assembly 208. Thetab portion 324 may be angled such that thetab portion 324 is substantially parallel to thebase portion 302 and the bottom 326, for efficiently securing of thetray assembly 208 within themount assembly 206. However, it may be contemplated that thetab portion 324 may be angled at any angle towards thetray assembly 208 to secure thetray assembly 208 within themount assembly 206. - Referring to
FIG. 6 , there is shown an enlarged perspective view of a portion of theconstruction machine 100, illustrating thetray assembly 208 being installed and/or removed from themount assembly 206. Thetray assembly 208 can be removed from themount assembly 206 by pulling it by thehandle 340. Therefore, to remove thetray assembly 208 from themount assembly 206, an operator lifts thetray assembly 208 with thehandle 340, to place thebottom 326 of thetray assembly 208 over thelip portion 310, and to disengage thetray assembly 208 from thetab portion 324. Further, thetray assembly 208 is removed from themount assembly 206 by sliding it over thelip portion 310 and the first and secondlongitudinal walls tray assembly 208 from tipping as it is removed. Installation of thetray assembly 208 is then a reverse procedure of its removal. - During normal operation of the
construction machine 100, some lubricant may drip off from thepin joint 118. The lubricant that drips from the pin joint 118 flows along theflanged portion 110 of themachine frame 102, towards thelubricant collecting assembly 200. The lubricant dripping from the pin joint 118 may either collect in thetray assembly 208 or in a plastic bag positioned inside thetray assembly 208. - The
wing portions longitudinal side walls tray assembly 208 create a large envelope to catch falling lubricant that drips along theinner side 202 offlanged portion 110. The dripping lubricant is caught due to thewing portion 336 of the firstlongitudinal side wall 328 being in abutment with theflanged portion 110 of themachine frame 102 and therefore the construction of thetray assembly 208 directs the lubricant into thetray assembly 208 by flowing along thewing portion 336. - After a certain period of time, the
tray assembly 208 may be required to be emptied. During such a service event, thetray assembly 208 is pulled by thehandle 340, to disengage thetray assembly 208 from thetab portion 324, and thebottom 326 of thetray assembly 208 rides along thelip portion 310 of themount assembly 206. While sliding, the first and secondlongitudinal walls mount assembly 206 guide thetray assembly 208 to reduce the occurrence of side-to-side tipping, thereby facilitating quick and efficient removal of thetray assembly 208. Further, thetray assembly 208 may be re-installed on themount assembly 206, once thetray assembly 208 is cleaned, in the same manner. Thetray assembly 208 is re-installed by pushing thetray assembly 208, and thebottom 326 of thetray assembly 208 rides along thelip portion 310 of themount assembly 206. While sliding, the first and secondlongitudinal walls mount assembly 206 guide thetray assembly 208 to reduce the occurrence of side-to-side tipping. Thetray assembly 208 slides above thelip portion 310 to be installed in themount assembly 206, and thetray assembly 208 engages with thetab portion 324, which acts to retain thetray assembly 208. Since thetray assembly 208 is removably positioned inside themount assembly 206, thetray assembly 208 is efficiently installed and removed.
