The materials fall from the hopper to the ground conveyor, and are transported to the yard through the conveyor to realize the unloading operation. Good and sufficient lubrication is a crucial condition to ensure the service life of the grab. Under the current conditions, the grab lubrication needs to be placed on the ground under the shutdown condition, and one lubricator operates the oiler, and another lubricator connects the oiler to the grab through the maintenance ladder to lubricate each point of the grab.

[0023] The utility model provides an oiling and lubricating device for a grab bucket of a ship unloader, comprising a centralized lubrication unit and a lubrication platform unit.
[0024] The centralized lubrication unit includes a motorized grease lubrication pump 1, a progressive distributor 2, a precision filter 3 and a high-pressure oil pipe 4. The motorized grease lubrication pump 1 is welded inside the support rod of the grab bucket 14 of the ship unloader. The precision filter 3 is threadedly fitted on the motorized grease lubrication pump 1. The oil outlet end of the motorized grease lubrication pump 1 is connected to the oil inlet end of the progressive distributor 2 through the high-pressure oil pipe 4. The oil outlet ends of the progressive distributor 2 are each connected to a high-pressure oil pipe 4 and mechanically connected to one end of the high-pressure oil pipe 4; the end of the high-pressure oil pipe 4 away from the progressive distributor 2 is mechanically connected to each hinge point of the grab bucket 14.
[0025] The motorized grease lubrication pump 1 may adopt the SJDB-M motorized grease lubrication pump, which is a plunger type lubrication pump, and completes the oil suction and oil pumping action through mechanical movement. Each oil outlet may be connected to a progressive distributor 2. The lubrication pump is a fully sealed structure, and an oil storage barrel is provided in the cavity, and lubricating oil may be placed in the oil storage barrel. A pressure plate type forced oil pressure device is adopted in the oil storage barrel, which ensures that the grease is pressed toward the oil suction port under various environments, and improves the pump suction phenomenon.
[0026] The progressive distributor 2 can adopt the CHGF1-0.2 type chip progressive distributor, which adopts the principle of hydraulic progressive oil distribution. The pressure medium drives the plunger in the distributor to reciprocate in sequence, and forcibly delivers the lubricating medium to each lubrication point. The pressure grease enters from the inlet of the distributor, pushing each plunger to circulate in sequence, so that each oil outlet continuously pumps grease to each lubrication point in sequence and uniformly.
[0027] The precision filter 3 may adopt the TGQ-30 precision filter, which has a higher nominal pressure and is suitable for high-pressure lubrication systems; this type of filter can filter both dry oil and thin oil.
[0028] The lubrication platform unit comprises a lubrication platform 5 , a pulley 6 , a steel wire rope 7 and a driving mechanism 8 .
[0029] One end of the lubrication platform 5 is hinged to the upper side of the grid plate 16 above the large funnel 15 of the ship unloader, and the hinge point of the lubrication platform 5 is close to the large funnel support 17 on the side of the grid plate 16. The large funnel support 17 near the hinge point of the lubrication platform 5 is equipped with a pulley 6 through bolts; the pulley 6 is arranged on the side of the large funnel support 17 close to the lubrication platform 5, the side away from the lubrication platform 5 and the upper end thereof.
[0030] The driving mechanism 8 is arranged on the supporting plate 18 on the side of the large funnel support 17 away from the lubrication platform 5. The driving mechanism 8 includes a motor 9, a coupling 10, a brake 11, a reduction box 12 and a reel 13. The output rod end of the motor 9 is mechanically connected to one end of the coupling 10. The coupling 10 is mechanically connected to the brake 11. The end of the coupling 10 away from the motor 9 is mechanically connected to the input shaft of the reduction box 12. The output shaft of the reduction box 12 is mechanically connected to the rotating shaft of the reel 13.
[0031] One end of the steel wire rope 7 is wound around the drum 13. After one end of the steel wire rope 7 away from the drum 13 passes through the pulley 6 arranged on the large funnel support 17 in sequence, it is connected to one end of the lubrication platform 5 away from the hinge point.
[0032] The lubrication platform unit is designed with a lubrication platform 5 that can be laid flat and retracted through a wire rope retracting device on the pillar 17 on one side of the large funnel 15. The operating drive mechanism 8 drives the lubrication platform 5 to rotate around its hinge point by retracting the wire rope 7, so as to adjust the angle of the lubrication platform 5 and realize the laying flat and retracting of the lubrication platform 5. The retracted lubrication platform 5 is vertically stored on one side of the large funnel pillar 17; the flat lubrication platform 5 is placed flat on the grid plate 16 above the large funnel 15. Since the centralized lubrication unit is welded inside the support rod of the grab 14 of the ship unloader, when lubricating, the grab 14 equipped with the centralized lubrication unit is placed above the grid plate 16 of the large funnel, and then the oiler is manually placed on the lubrication platform 5, and then the oiler outlet is connected to the oil inlet of the motorized grease lubrication pump 1 through a high-pressure oil pipe, and finally the oiler is started to lubricate the hinge points of the grab in turn. It can be seen that compared with the traditional solution, the utility model is simple to operate, does not require high-altitude operations, effectively improves work efficiency, reduces safety hazards, and achieves a uniform lubrication effect on the grab hinge point.
[0033] The specific usage and function of this embodiment are as follows:
[0034] During the lubrication operation, first place the grab 14 equipped with the centralized lubrication unit on top of the large funnel grid plate 16, then manually place the oiler on the lubrication platform 5, then connect the oil outlet of the oiler to the oil inlet of the motorized grease lubrication pump 1 through a high-pressure oil pipe, and finally start the oiler to lubricate the hinge points of the grab 14 in turn.
[0035] In summary, the utility model is easy to operate and can be operated by one lubricating personnel without climbing, thereby reducing the safety hazards of the workers, and each hinge point is lubricated in turn to achieve a uniform lubrication effect on the grab hinge point.
