[0023] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples, and the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0024] As Figures 1 to 4 shown, the present invention provides a deviation prevention device for a wire rope differential mechanism for water treatment trash interception, which includes a frame 3, a driving mechanism, and a moving pulley 2 connected to the driving mechanism. A fixed pulley 1 connected to the moving pulley 2 by a wire rope is arranged inside the frame 3, and the driving mechanism is connected to the moving pulley 2 through a fixed frame 6. The driving mechanism drives the moving pulley 2 to reciprocate inside the frame 3 to realize the length adjustment of the wire rope between the moving pulley 2 and the fixed pulley 1. After the power is turned on, the driving mechanism drives the moving pulley 2 to reciprocate inside the frame track 9 through a lead screw 4, regulates the distance between the moving pulley 2 and the fixed pulley 1, thereby adjusting the working length of the wire rope, and achieving the purpose of controlling the opening and closing angle of the rake bucket.

[0025] As Figure 1 、 3 、4 shown, a sliding shaft 11 is slidably arranged inside the frame 3. The fixed frame 6 is fixedly connected to the sliding shaft 11. The fixed frame 6 is driven by a T-shaped rod 5 to reciprocate inside the frame 3, thereby providing power to the sliding shaft 11, enabling the sliding shaft 11 to reciprocate inside the frame track 9, driving the moving pulley 2 to reciprocate inside the frame 3, regulating the distance between the moving pulley 2 and the fixed pulley 1, thereby adjusting the working length of the wire rope, and achieving the purpose of controlling the opening and closing angle of the rake bucket.

[0026] The sliding shaft 11 is in a frustum shape. The large-diameter end is connected to the fixed frame 6, and the small-diameter end is inserted into the frame track 9. The moving fixed frame 6 drives the sliding shaft 11 to move on the frame track 9, thereby driving the moving pulley 2 to move, adjusting the working length of the wire rope, and preventing the moving pulley 2 from derailing and causing damage to the device, improving the stability and reliability of the device.

[0027] As Figure 1 、 2As shown in the figure, a rack track 9 is provided on the side of the rack 3, and a sliding shaft 11 is slidably arranged in the rack track 9. The rack track 9 corresponds to the sliding shaft 11. In the direction close to the motor 1, the size of the rack track 9 corresponds to the large-diameter side of the sliding shaft 11, and the size on the side close to the fixed pulley 1 on the left corresponds to the small-diameter side of the sliding shaft 11. The size in the middle of the entire track corresponds to the diameter size when the sliding shaft 11 slides and contacts the rack 3. This structure prevents the moving pulley 2 from slipping out of the track, causing device failures and thus unable to operate normally.

[0028] The fixed pulley 1 is connected to the rack 3 through a fixed rod 10. The fixed pulley 1 is arranged on the left side inside the rack 3, on the left side of the moving pulley 2, which plays a role in fixing the position of the steel wire rope. When the moving pulley 2 moves to adjust the working length of the steel wire rope, it plays a role of a fixed point for the steel wire rope, facilitating the adjustment of the length of the steel wire rope.

[0029] The driving mechanism includes a motor 7, a lead screw 4, and a T-shaped rod 5. One end of the lead screw 4 is connected to the output end of the motor 7. After the power is turned on, the lead screw 4 outputs power through the motor 7 and makes a reciprocating motion inside the rack 3, thereby driving the T-shaped rod 5 connected to the lead screw 4 to move, indirectly driving the moving pulley 2 to move on the rack track 9 of the rack 3 and adjusting the length of the steel wire rope.

[0030] The left end of the lead screw 4 is fixedly connected to the right end of the T-shaped rod 5. While the lead screw 4 makes a reciprocating motion, it drives the T-shaped rod 5 to make a reciprocating motion, thereby driving the fixed frame 6 connected to the left end of the T-shaped rod 5 to make a reciprocating motion.

[0031] The left end of the T-shaped rod 5 is connected to the fixed frame 6. While the T-shaped rod 5 makes a reciprocating motion, it drives the fixed frame 6 to make a reciprocating motion, thereby making the sliding shaft 11 move on the rack track 9 and driving the moving pulley 2 to also make a reciprocating motion to adjust the length of the steel wire rope.

[0032] One output end of the motor 7 is fixedly connected to the right side of the rack 3. The lead screw 4 is connected to the output end of the motor 7, passes through the right end of the rack 3 and extends into the interior of the rack 3 to be connected to the moving pulley 2. After the motor 7 is powered on, the output end drives the lead screw 4 to make a reciprocating motion inside the rack 3, thereby driving the moving pulley 2 to move and adjusting the distance between the moving pulley 2 and the fixed pulley 1 to achieve the purpose of regulating the length of the steel wire rope.

[0033] The moving pulley 2 is arranged inside the rack 3. Both sides of the moving pulley 2 are fixedly connected to the fixed frame 6, and the fixed frame 6 is also fixedly connected to the sliding shaft 11. The fixed frame 6 provides power through the drive of the T-shaped rod 5 and the lead screw 4 to make the moving pulley 2 move left and right inside the rack 3, adjusting the distance between the moving pulley 2 and the fixed pulley 1, thereby adjusting the working length of the steel wire rope.

[0034] Usage method of the utility model: After the power is turned on, the driving mechanism drives the moving pulley 2 to reciprocate within the frame track 9 through the lead screw 4, adjusts the distance between the moving pulley 2 and the fixed pulley 1, thereby adjusting the working length of the steel wire rope, and achieving the purpose of controlling the opening and closing angle of the grab bucket. Moreover, the moving pulley 2 will not derail and cause damage to the device, improving the stability and reliability of the device and reducing the occurrence of equipment failure rate.
