Description
Technical field
The utility model relates to lift facility field, is specifically related to a kind of oil lubrication device for tractor of elevator.
Background technology
Elevator, the especially elevator of vertical lift is dependent on the pulling force of many pull ropes and makees VTOL in the air and run, in running, once pull rope ruptures, it would be possible to cause casualties, the consequences such as device damage, therefore pull rope abrasion is reduced, the service life extending pull rope can effectively prevent pull rope from rupturing, at present, the means reducing pull rope abrasion are varied, the oil lubrication being to increase between pull rope and pulley wherein more commonly used, although this kind of method is simply effective, but relatively waste lubricating oil, use too much lubricating oil not only can increase the maintenance cost of elevator, also pollute the environment, therefore the highly desirable abrasion that can be reduced pull rope by other means of people.There is many shortcomings in traditional centralized lubricating system.
Utility model content
For problem above, the utility model provides a kind of oil lubrication device for tractor of elevator, can effectively solve the problem in background technology.
nullTo achieve these goals，The technical solution adopted in the utility model is as follows: a kind of oil lubrication device for tractor of elevator，Including oil feeder、Injection apparatus and pumping plant，The two ends of described oil feeder are connected with pumping plant and injection apparatus respectively，Described pumping plant includes liquid-pressure pick-up，Described liquid-pressure pick-up is connected with two lubricating pumps and some gravity sensors in turn，Described gravity sensor is connected with filling conduit reversal valve in turn、Gasoline pump and depot fat fill，Described oil feeder includes left end cap and right end cap，Described right end cap is provided with proximity Hall switch，In the middle of described left end cap and right end cap, valve body is installed，The upper end of described valve body is provided with plunger，The both sides of plunger are provided with A chamber and B chamber，The middle part of described valve body is provided with spool，One end of spool is connected with electromagnet push-rod and electromagnet，Its other end is full of spring，Described spool is connected with oil-out and oil-in，Described injection apparatus includes nozzle，One end of described nozzle is connected with oil-out，The other end is connected with air valve in turn、Tracheae.
Preferably, described liquid-pressure pick-up is connected with electromagnet push-rod.
Preferably, one end of described plunger is provided with magnet.
The beneficial effects of the utility model: the utility model lubricating grease enters A chamber from oil-in, plunger is promoted to move right, simultaneously the oil pressure in B chamber to oil site, until plunger is close to right end cap, plunger stops mobile, lubricating grease stops flowing, magnet reaches the detection range of proximity Hall switch, proximity Hall switch output switching value now, gravity sensor also has how many greases in detecting pump by the weight measuring lubricating pump, also require that display is when remaining grease less than constant weight in real time, gasoline pump starts, fill oil pumping from depot fat and be added to lubricating pump, because there being two lubricating pumps, so gasoline pump outlet has added a filling conduit reversal valve, can realize that a gasoline pump refuels to two lubricating pumps, save lubricating oil, environmental protection and low cost, can effectively reduce the abrasion of hauling machine.
