Abstract
The invention discloses an automatic lubricating device of a crane pulley, belonging to the field of crane mechanical devices. A sealed lubricant storage device at the side surface of the fixed end of a fixed pulley of a pulley block is internally provided with a lubricant for lubricating, the lower end of the fixed pulley is provided with an outlet controlled by a flow switch, the outlet is connected to a cavity at the axle center of the fixed pulley through a lubricant pipe, the lubricant reaches a groove on the surface of the fixed pulley through a lubricant outlet channel distributed in the cavity, a steel rope is wound on the pulley block and connected with a lifting motor, and the switch is connected with an operating floor for control. In a crane working process, the automatic lubricant always provides the lubricant for the fixed pulley and the steel rope which is in contact with the steel rope, and the consumption of the lubricant is controlled by the flow switch so as to correspond to different mining conditions. The automatic lubricating device is convenient and controllable without adding the lubricant manually, thus safety accidents such as shortening of service life of the steel rope and the pulley block, damaged pulley, broken steel rope and the like due to friction are reduced.
Description
Technical field
The present invention relates to the lifting equipment field, specifically crane pulley automatic lubricator.
Background technique
Straddle truck is provided with hoisting drum, and Wound steel rope on the hoisting drum, wire rope are walked around sheave block lifting goods.Because of wire rope is walked around sheave block, there is friction between pulley and wire rope, simultaneously because straddle truck is an open work machinery; For reducing the friction of wire rope and sheave block, make lifting smoothly, and the working life that prolongs sheave block and wire rope; It is lubricated to need to add finish; But manual application of lubricant labor intensity is big, and is lubricated untimely, not thorough.The large scale sheave block of straddle truck is big is inconvenient to adopt original traditional method lubricated, and shortens the life-span of wire rope and sheave block, and severe patient can cause pulley to damage, security incidents such as wire cable rupture.
Summary of the invention
In view of the defective that prior art exists, the purpose of this invention is to provide the automatic lubricator of a kind of sheave block and wire rope.
For realizing above-mentioned purpose; The technological scheme that the present invention adopted is a kind of crane pulley automatic lubricator; The finish storage of a sealing of the static pulley fixed end side of sheave block, the lubricating oils that is used to lubricate is equipped with in the inside, and the lower end has the outflow opening of flow switch control to be inserted in the chamber in static pulley axle center by an oil pipe; Lubricating oils arrives the groove on static pulley surface through the oil discharge passage that distributes in the chamber; Wire rope is wrapped on the sheave block, and is connected with the lifting motor, and switch is connected control with operating table.Automatic lubricator is synchronoused working with the lifting motor; Flow switch is adjusted lubricating oils automatically and is got into the speed in the fixed pulley axis chambers of the heart; And from oil discharge passage, flow out uniformly, arrive in the groove on the surface that contacts with wire rope on the static pulley, and be brought on wire rope and the movable pulley.
After adopting such scheme; Compared with prior art have following beneficial effect: the present invention is in the straddle truck working procedure; Automatic lubricator is always static pulley and with the wire rope that contacts with it lubricating oils is provided, and the metering of oiling agent is controlled by flow switch, deals with different industrial and mineral conditions.Convenient, controlled, need not hand oiling, reduce because of friction causes the life-span that shortens wire rope and sheave block anti-limited slip wheel damage, security incidents such as wire cable rupture.
Description of drawings
Fig. 1 is a kind of structural representation of crane pulley automatic lubricator.
Fig. 2 is a kind of crane pulley automatic lubricator partial schematic sectional view.
Among the figure: 1, promote motor, 2, suspension bracket, 3, the finish storage, 4, lubricating oils, 5, flow switch, 6, oil pipe, 7, oil discharge passage, 8, static pulley, 9, wire rope, 10, movable pulley.
Embodiment
Fig. 1; In the structure intention of crane pulley automatic lubricator shown in Figure 2; The finish storage 3 of a sealing of the static pulley 8 fixed end sides of sheave block, the lubricating oils 4 that is used to lubricate is equipped with in the inside, and the lower end has the outflow opening of flow switch 5 controls to be inserted in the chamber in static pulley 8 axle center by an oil pipe 6; Lubricating oils 4 arrives the groove on static pulley surface through the oil discharge passage 7 that distributes in the chamber; Wire rope 9 is wrapped on the sheave block, and is connected with lifting motor 1, and switch is connected control with operating table.Automatic lubricator is synchronoused working with lifting motor 1; Flow switch 5 is adjusted the speed that lubricating oils 4 gets in the chambeies, static pulley 8 axle center automatically; And from oil discharge passage 7, flow out uniformly; Arrive in the groove on the surface that contacts with wire rope 9 on the static pulley 8, and be brought on wire rope 9 and the movable pulley 10.
When straddle truck is worked; Automatic lubricator is worked simultaneously; Speed flowrate switch 5 according to promoting motor 1 adjust automatically, makes lubricating oils 4 in the finish storage 3 get in the chamber in static pulley 8 axle center and outflow from oil discharge passage 7 uniformly, in the groove on the surface that contacts with wire rope on the arrival static pulley; Thereby have a certain amount of lubricating oils on the wire rope, and be brought on the movable pulley.When straddle truck quit work, the flow switch 5 of its automatic lubricator also cut out, and unlubricated finish 4 flows out, self oiling when accomplishing work, and inoperative stops automatically.
