Problems solved by technology

[0002] At present, during the use of the screw hoist, the screws are almost all exposed to the outside. Even if there are steel pipes protected on the outside, there are no vents. The long-term internal humidity will accelerate the corrosion of the screw. The wind and rain erosion still cannot play a fundamental role in protecting the screw.

Embodiment Construction

[0017] According to the present invention, the protective casing 1 is arranged on the outside of the screw 51 of the screw hoist 5, the protective casing 1 wraps the screw 51 inside, and the side of the protective casing 1 is provided with several ventilating seats protruding from the protective casing 1 2. The air-permeable seat 2 communicates with the space formed by the protective sleeve 1 and the screw rod 51; the air-permeable seat 2 is provided with an air-permeable bolt 3 that cooperates with the air-permeable seat 2.

[0018] The protective casing 1 is fixedly connected to the screw hoist 5 through connecting bolts 4 and washers.

[0019] The joint of the air-permeable seat 2 and the air-permeable bolt 3 is covered with a sealing ring 6 .

[0020] The air-permeable seat 2 is arranged obliquely downward.

[0021] The working process of the present invention is as follows: first, the protective casing 1 is connected and fixed with the screw hoist 5 with the connecting b...

Abstract

The invention relates to a screw protecting device for a screw headstock gear. The device provided by the invention comprises a protecting sleeve (1) which is arranged out of a screw (51) of the screw headstock gear (5), and the protecting sleeve (1) wraps the screw (51). The device is characterized in that a plurality of ventilating bases (2) protruding out of the protecting sleeve (1) are arranged on the side portion of the protecting sleeve (1), and the ventilating bases (2) communicate with a space formed by the protecting sleeve (1) and the screw (51); ventilating bolts (3) matched with the ventilating bases (2) area arranged on the ventilating bases (2). The invention provides the screw protecting device for the screw headstock gear. The device externally protects the screw, and the ventilating bolts are arranged around the protecting sleeve, and air circulation in the protecting sleeve is kept by the ventilating openings, so that the working environment is guaranteed.

Description

technical field [0001] The invention relates to a screw protection device for a screw hoist and belongs to the technical field of screw hoists. Background technique [0002] At present, during the use of the screw hoist, the screws are almost all exposed to the outside. Even if there are steel pipes protected on the outside, there are no vents. The long-term internal humidity will accelerate the corrosion of the screw. The wind and rain erosion still cannot play a fundamental role in protecting the screw. Contents of the invention [0003] In view of the above defects, the present invention aims to provide a screw protection device for screw hoists that can provide external protection for the screw, and a ventilating bolt is provided around the protective cover, and the air vent keeps the air circulation inside the protective cover to ensure the working environment. . [0004] For this reason, the technical solution adopted by the present invention is: the protective sle...
