Description
Technical field
The utility model relates to crane gear field, particularly a kind of hoist travelling wheel exposed gear lubricating system and comprise its hoist.
Background technique
Thereby the walking driving mode of hoist is generally motor drives the exposed gear on travelling wheel to drive travelling wheel to turn round by deceleration system.Because deceleration system is open except speed reducer, traditional lubricating system is that apply grease is lubricated, 1), the grease smeared can not be too many there are a lot of defects in which:, because grease is extruded during gear engagement, drop to ground pollution environment and waste grease in implementation process; 2), grease can not keep always, the oil film of formation repeatedly will disappear after engagement, the grease that is extruded to side cannot flow back into Surface of action, needs frequent apply grease; 3), fatten is lubricated wastes time and energy, especially goliath travelling wheel is many, needs the construction of stopping: smear a part of gear teeth, travelling wheel rotates smears other gear teeth, the normal production work of the equipment that had influence on again.
The lubricated quality of exposed gear has influence on the wearing and tearing of the gear teeth, finally causes the inefficacy of meshing between gear.When lubricant grease lacks, Surface of action without oil film after exposed gear open type get rusty, Surface of action engenders spot corrosion, the attenuation of wheel odontotripsis, gear teeth sharpening, after back lash increases, during travelling wheel running, vibration increases, and may destroy steel structure, once gear teeth polishing, hoist has lacked one group of driving mechanism, and other mechanism's loads increase, and likelihood of failure increases, and the exposed gear of changing walking is a consumption cost consuming time, the repair work very large to Influence of production.

Positive progressive effect of the present utility model is: the utility model proposes the thicker gear oil of employing and replace grease, thereby utilize electromagnetic valve oil circuit to open and close the function that realizes drop lubrication, by the controllability of solenoid valve, realize the precision of oily automation, volume read-out, time saving and energy saving, realize lubricated to travelling wheel exposed gear efficiently, and whole system simple and easy light and handy, easy for installation, maintenance is convenient, cost is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of the hoist travelling wheel exposed gear lubricating system of the utility model preferred embodiment.
Fig. 2 is the structural representation of the fuel tank of the utility model preferred embodiment.
Fig. 3 is the partial schematic diagram of the hoist of the utility model preferred embodiment.
Embodiment
Lift a preferred embodiment below, and carry out by reference to the accompanying drawings the clearer the utility model that intactly illustrates.
The main component of hoist travelling wheel exposed gear lubricating system of the present utility model are: fuel tank 1, fuel path switch, oil pipe 3, solenoid valve 4, flow control valve 5(flow switch), oil dripping tube 6 and joint form, as shown in Figure 1.
Consider that lubricant housings is exposed gear, system adopts No. 220 larger gear lubricant of stickiness.The gear oil of this model has stronger stickiness, can avoid the gear oil flank of tooth that directly trickles, when gear is intermeshing, gear oil is extruded to tooth root, and when not meshing, gear oil is slowly spread out again, Surface of action has oil lubrication all the time, thereby realizes the permanent lubricated of gear.
This lubrication system is mainly used in the travelling wheel exposed gear lubricating of crane travelling gear, because the travelling wheel interval of the installation exposed gear of crane travelling gear is larger, the corresponding one group of exposed gear of every cover lubrication system for this reason, can solve like this oil circuit long, lay difficult problem, can increase the cable of solenoid valve 4 although it is so, but the laying of solenoid valve 4 cables is more convenient easily than pipeline.
The electric control system of this lubrication system and hoist interlock, be that hoist walking operation starts, lubrication system just starts (being that solenoid valve 4 starts), traveller stops lubrication system and also stops (being that solenoid valve 4 cuts out), avoid lubricant oil to lubricate all the time in a certain gear teeth, realized lubricated uniformity, electrical system can independently be closed unlatching simultaneously, but after gear lubrication abundance, can manual-lock system.
Because lubrication system is in outdoor application, often expose to the sun and rain and may with the workpiece scratching of site operation, fuel tank 1 adopts iron sheet manufacture antirust processing for this reason.For the ease of checking oil mass, fuel tank 1 is installed oil level indicator 11.Fuel tank 1 oil outlet installs filtering head 12 additional, and higher than fuel tank 1 bottom 5mm, stops up solenoid valve 4, as shown in Figure 2 thereby the foreign material of bringing into while avoiding refueling enter oil circuit.Because the oil mass that system needs is little, the about 3L of fuel tank 1 oil reserve, and the latus rectum of solenoid valve 4 is 1/4 inch and just can meets, for safety utilization of electric power, solenoid valve 4 employing direct current 24V power.In the present embodiment, adopt ball valve switch 2 as fuel path switch, the effect of ball valve switch 2 is in order to close oil mass when solenoid valve 4, flow control valve 5 and oil pipe 3 are changed in maintenance, and other time ball valve switch 2 all open, only by solenoid valve 4, carry out the break-make of oil circuit control.Under condition, oil pipe 3 is as adopted the easy corrosion of seamless steel pipe in the open, and as adopted copper pipe, cost is too high, and native system adopts PU(polyurethane) oil pipe, joint all adopts rapid pipe joint 7, and so cost is low, and installation is simple, and maintenance is convenient.
The feature of the utility model lubrication system is the controllability that has realized oilgear oil oil mass, the switching of solenoid valve 4 oil circuit controls, and flow control valve 5 is controlled speed and the size of oil dripping.
Shown in Fig. 3, demonstration be the part of hoist of the present utility model, it comprises a chassis 8, a chassis equalizer bar 81, some travelling wheel exposed gears 9 and some travelling wheel exposed gear case (not shown)s.The position that fuel tank 1 is installed higher than exposed gear, for example, be installed on chassis equalizer bar 81, and gear oil can be dripped smoothly.Opposite opened gear house is offered through hole (not shown), solenoid valve 4 is installed on mounting bracket 41, mounting bracket 41 requires a little more than exposed gear peak, connecting pipeline, oil dripping tube 6 is installed, oil dripping tube 6 stretches into from exposed gear case, and oil dripping mouth 61 is 2～3 teeth of the highest tooth of exposed gear relatively, avoid gear oil directly to splash into the non-Surface of action of tooth root.
Although more than described embodiment of the present utility model, it will be understood by those of skill in the art that this only illustrates, protection domain of the present utility model is limited by appended claims.Those skilled in the art is not deviating under the prerequisite of principle of the present utility model and essence, can make various changes or modifications to these mode of executions, but these changes and modification all fall into protection domain of the present utility model.
