Abstract
The utility model discloses a dustproof device of a lifting screw of a balance crane. The dustproof device comprises a corrugated pipe protecting cover which is installed on the circumferential periphery of the exposed portion of a lifting combination portion of the lifting screw of the balance crane, two ends of the protecting cover are respectively provided with a flange plate, the upper flange plate is connected with the bottom of a screw hanging ring through a bolt, and the lower flange plate is connected with the upper portion of a speed changing box gland through a bolt. The corrugated pipe protecting cover is installed on the periphery of the screw of the balance crane and can ascend and descend synchronously along with the screw, normal operation is not influenced, dust and rain can be prevented from entering the screw, maintenance load is effectively reduced, and service life is beneficially prolonged.
Description
Technical field:
The utility model relates to the proofing dust and protecting of reciprocal drive gadget, particularly a kind of dust guard that is applicable to the balance crane elevating screw.
Background technique:
Existing balance crane elevating screw all is that the lower end is rotatably connected on the gearbox gland, and the upper end links to each other with the arm driving mechanism through the leading screw suspension ring.Because balance crane when work carries out in the field mostly in the open, the periphery, lifting connecting part of its elevating screw is not installed dust guard again, so enter dust and wind and rain from the leading screw exposed parts easily, has significantly reduced the working life of balance crane.
Summary of the invention:
The purpose of this utility model provides and a kind ofly can prevent effectively that dust, wind and rain from entering in the leading screw of balance crane, is conducive to improve the balance crane balance crane elevating screw dust guard in working life.
The technical solution of the utility model is finished as follows, balance crane elevating screw dust guard, it includes a corrugated pipe protective sheath, it is characterized in that: corrugated pipe protective sheath is installed in the elevating screw lifting connecting part exposed parts periphery of balance crane, be respectively equipped with a flange plate at the two ends of protecting cover, upper flange plate is connected with bolt on the bottom surface of leading screw suspension ring, and lower flange is connected above the gearbox gland with bolt.
The utility model is installed in the leading screw periphery of balance crane with corrugated pipe protective sheath, and along with the leading screw synchronization lifting, the neither normal operation of influence can avoid dust and wind and rain to enter in the leading screw again, has reduced amount of maintenance effectively, is conducive to improve working life.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
The utility model is that the elevating screw 6 lifting connecting part exposed parts periphery at a balance crane are equipped with a corrugated pipe protective sheath 3, be respectively equipped with a flange plate at the two ends of protecting cover, upper flange plate 4 usefulness bolts are connected on the bottom surface of leading screw suspension ring 5, and lower flange 2 usefulness bolts are connected above the gearbox gland 1.During work, protecting cover and then elongates or shrinks, and gearbox is above exposes leading screw and just can not enter dust and wind and rain.
