Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, and in particular relates to a rust removal device for bridge steel cables. Background Art

[0002] Steel cables are generally used in bridge construction, especially in the construction site of large bridges, where a lot of steel cables are used. The steel cables will rust after being exposed to the air for a long time, and the situation will be more serious when there is rain. Therefore, the steel cables need to be derusted after being used for a period of time. However, the steel cables for bridge construction are mostly set in suspended positions, and manual rust removal is very dangerous and cumbersome. Therefore, we proposed a bridge steel cable rust removal device to solve the above problem. Utility Model Content

[0006] It is further defined that the rotating plate is provided with a mounting groove, the movable seat is movably mounted in the mounting groove, a fixing rod is fixedly mounted at the end of the movable seat, the end of the fixing rod passes through the rotating plate, and a compression spring is sleeved on the fixing rod between the movable seat and the wall of the mounting groove. With such a structural design, under the action of the compression spring, the movable seat will drive the driven wheel to move toward the driving wheel, cooperate with the driving wheel to clamp the bridge cable, and is suitable for cables of different diameters.

[0007] It is further defined that a fixed cylinder is fixedly installed on the rotating plate, the end of the fixed rod passes through the fixed cylinder, an inclined support cylinder is fixedly installed on the fixed cylinder, the inclined support cylinder is connected with the fixed cylinder, an internal thread is provided on the inner wall of the inclined support cylinder, a locking bolt is threadedly connected on the inclined support cylinder, and a stopper is rotatably installed on one end of the locking bolt extending into the inclined support cylinder. With such a structural design, when the driven wheel cooperates with the driving wheel to clamp the bridge cable, the stopper can be made to contact the fixed rod through the locking bolt, so that the movable seat is in a locked state, avoiding loosening of the driven wheel during use, which affects the use.

[0008] It is further defined that the clamping member includes an L-shaped movable block, a return spring and a toggle block, a slot is provided on the U-shaped shell at a position corresponding to the clamping block, an L-shaped groove connected to the slot is provided inside the U-shaped shell, one end of the L-shaped groove penetrates to the outer surface of the U-shaped shell, the L-shaped movable block is movably installed in the L-shaped groove, a wedge surface is provided at the upper end of the L-shaped movable block, the other end of the L-shaped movable block extends out of the L-shaped groove, the return spring is fixedly installed between the L-shaped movable block and the L-shaped groove wall, when the clamping block extends into the slot, the L-shaped movable block is clamped with the clamping block, and the toggle block is fixedly installed at one end of the L-shaped movable block extending out of the L-shaped groove. Such a structural design is simple in structure and easy to use.

[0009] It is further defined that the two C-shaped cylinders are centrally symmetrically arranged on the U-shaped housing. With such a structural design, the two C-shaped cylinders are used in coordination to ensure the coverage of the rust removal wire and avoid rust removal dead corners when the rust removal device is working.

[0010] It is further defined that the driving wheel and the driven wheel are both provided with an arc-shaped annular groove, and a plurality of anti-slip strips are fixedly installed in the arc-shaped annular groove. With such a structural design, the arc-shaped annular groove can fit the steel cable more closely, and the anti-slip strips can increase the friction between the driving wheel and the driven wheel and the steel cable, thereby driving the entire rust removal device to move on the bridge cable to complete the rust removal work.

[0011] The utility model adopting the above technical solution has the following advantages:

[0012] In the utility model, when the rotating plate is engaged with the U-shaped shell, the movable seat and the driven wheel will cooperate with the driving wheel to clamp the bridge cable. At this time, the motor drives the driving wheel to rotate, thereby driving the rust removal device to move along the bridge cable, causing the steel wires inside the two C-shaped cylinders to continuously rub against the bridge cable, thereby removing rust from it. The utility model is safe, reliable and more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
