Background technology
In the prior art, the lubricated cooling of vibratory chamber's bearing of vibrating hammer, general common employing splash lubrication mode, but because the particularity of vibratory chamber's structure, often rely on the high speed rotation of eccentric block in the vibratory chamber and gear and got rid of to the lubrication oil of vibratory chamber's cabinet wall and be difficult to flow to or drop onto bearing, cause the dry friction of bearing and damage, increased the probability that initial failure appears in bearing, the application life of reducing bearing greatly.Have a strong impact on the normal construction of vibrating hammer, reduce the efficiency of construction of work unit greatly.In addition, continuous increase along with the pile foundation project of marine main facilities, the vibrating hammer that the market demand exciting force is bigger, simultaneously, it is very frequent to face upward the pile driving construction operation of bowing, therefore, the splash lubrication mode that adopted of vibratory chamber's bearing of existing vibrating hammer can't adapt to the development need of large-scale pile foundation construction.
Summary of the invention
The objective of the invention is to according to the deficiencies in the prior art, provide that a kind of lubricated cooling effect is obvious, working stability reliably, effectively improves bearing application life, and satisfies vibratory chamber's bearing cooling and lubricating system of the vibrating hammer of large-scale pile foundation construction requirement.
The present invention is achieved through the following technical solutions:
A kind of vibratory chamber's bearing cooling and lubricating system of vibrating hammer, wherein, vibrating hammer involving vibrations chamber, oil-storing cup, oil leab, vibrating shaft, bearing (ball) cover, lubricating oil sump, bearing; Vibratory chamber's bearing cooling and lubricating system comprises two groups of forced lubrication devices, and they are installed on the outer wall of two sides, front and back of vibratory chamber respectively and comprise that separately one is installed in the oil pump on one of bearing (ball) cover and by oil pump lubrication oil is transported to bearing (ball) cover carries out forced feed lubrication to bearing lubrication oil feed mechanism from lubricating oil sump.
Above-mentioned lubrication oil feed mechanism comprises fuel sucking pipe, flowline, branch oil clot, lubricating oil pipe; One end of fuel sucking pipe is connected to the lubricating oil sump of vibratory chamber bottom by joint, and the other end of fuel sucking pipe is connected to the oil-in of oil pump; Oil clot was installed on vibratory chamber's external wall of upper portion with screw in described minute, one end of described flowline connects the oil-out of oil pump, the other end of flowline is connected in the import of branch oil clot, divides the outlet of oil clot then to be connected respectively on the bearing (ball) cover of vibratory chamber's one side by lubricating oil pipe; The quantity of lubricating oil pipe is to be provided with according to the quantity of bearing (ball) cover.
On the above-mentioned forced lubrication device oil temperature sensor is set, lubricating oil temperature is monitored in real time; When lubricating oil temperature 〉=55 ℃, send the too high warning of lubricating oil temperature.
Vibratory chamber's bearing cooling and lubricating system of vibrating hammer of the present invention has following good effect and advantage:
By the mode that adopts splash lubrication and forced feed lubrication to combine, vibratory chamber's bearing that can guarantee vibrating hammer under any circumstance can both obtain lubricated reliably cooling, avoid bearing to kill the fault that burns out because of dry friction, prolong the application life of bearing greatly, improved the operating efficiency of vibrating hammer; Simultaneously; because forced lubrication device is equipped with temperature pick up; when the regulation of lubricating oil temperature above 55 ℃ requires; system gives a warning and points out the constructor to take measures rapidly; avoid bearing to can not get in time lubricating the dry friction situation occurring, vibratory chamber's bearing of vibrating hammer is effectively protected because of overheated.
Description of drawings
Below in conjunction with drawings and Examples the present invention is further described:
Fig. 1 is the structural representation of vibratory chamber of the present invention bearing cooling and lubricating system;
Fig. 2 is that the A-A of Fig. 1 is to sectional view;
Fig. 3 is the left view of Fig. 1;
