Description

Technical Field

[0001] This utility model relates to a guide rod straightening device for a hydraulic loading and unloading station, and more particularly to an anode guide rod straightening device for electrolytic aluminum in a hydraulic loading and unloading station. Background Technology

[0002] In the field of electrolytic aluminum, the anode guide rod is a crucial component. During production, the anode guide rod needs to be transferred. In the hydraulic loading and unloading station, the palletized anode guide rod is hoisted. During hoisting, the anode guide rod needs to be straightened so that its head can be accurately clamped and lifted. Existing technology uses paired inclined rollers to straighten the anode guide rod. The pair of inclined rollers forms a downward-opening V-shape. During operation, the inclined rollers rotate with the frame, and the openings of the pair of inclined rollers turn towards the anode guide rod. As rotation continues, the distance between the points of contact between the pair of inclined rollers and the anode guide rod gradually decreases, thus acting on the anode guide rod to straighten it. However, during the straightening process of the inclined rollers, the anode guide rod is prone to jamming. If the inclined rollers jam the guide rod, continued rotation will lift the entire jammed guide rod assembly upwards, causing deformation and weld breakage of the guide rod positioning frame and the main beam rectangular tube, rendering the equipment unusable. Furthermore, this structure also has a relatively small straightening range for the guide rod. Utility Model Content

[0003] The purpose of this utility model is to provide a guide rod straightening device for a hydraulic loading and unloading station, so as to solve the problem that the guide rod straightening device in the prior art is prone to jamming the guide rod.

[0004] To solve the above problems, the hydraulic loading and unloading station guide rod straightening device involved in this utility model adopts the following technical solution: A hydraulic loading and unloading station guide rod straightening device includes a main frame, on which rotating frames arranged with gaps and extending outward are rotatably mounted. Each rotating frame is hinged to a connecting rod, and the rotating frames and connecting rods in pairs form a parallelogram mechanism. The rotating frame on the left side is hinged to the piston rod of a driving cylinder, and the cylinder body of the driving cylinder is hinged to the main frame. A transverse roller is provided on the main frame between each pair of adjacent rotating frames. Both ends extend towards the two adjacent rotating frames. The upper part of the rightmost rotating frame is rotatably equipped with an upper roller, and the lower part of the leftmost rotating frame is rotatably equipped with a lower roller. The upper and lower parts of the remaining rotating frames are respectively rotatably equipped with an upper roller and a lower roller. The extension direction of each upper roller and lower roller is the same as the extension direction of the rotating frame. On the left rotating frame of each of the two adjacent rotating frames, a slanted roller is rotatably equipped. The upper part of the slanted roller is close to the main frame, and the lower part is far away from the main frame. The slanted roller is located to the right of the lower roller on the same rotating frame.

[0005] The rotating frame is in the shape of a round rod. One end of the rotating frame is rotatably assembled onto the main frame, while the other end of the rotating frame extends freely.

[0006] The rotating frame is hinged to the connecting rod via an ear-shaped protrusion fixed on its circumference.

[0007] The end of the ear-shaped protrusion of the leftmost rotating frame is hinged to the piston of the driving cylinder.

[0008] Each upper and lower roller is rotatably mounted on the rotating frame via two lugs. The lugs are fixed to the rotating frame, and the upper and lower rollers are rotatably mounted on the two lugs.

[0009] The inclined roller is mounted on the rotating frame via an inclined column fixed to the rotating frame. The upper end of the inclined column is fixed to the rotating frame, and the inclined roller is rotatably mounted on the side of the inclined column close to the main frame.

[0010] In use, the guide rod from the tray moves vertically between the rotating frames. The horizontal roller abuts against one side of the guide rod to straighten it in one direction. The driving cylinder extends, and each rotating frame rotates to the left. The upper and lower rollers on the adjacent rotating frames act on the opposite two sides of the guide rod, while the oblique roller acts on the last side, thus straightening the guide rod and preventing it from jamming.

[0016] To make the technical objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model; that is, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0017] Specific embodiments of the hydraulic loading and unloading station guide rod straightening device involved in this utility model are described below. Figures 1-4 In this document, the left and right directions are arbitrarily determined before definition and remain unchanged after definition, without constituting a limitation on the scope of protection. Five rotating frames 2 are rotatably mounted on the main frame 1. Each rotating frame 2 is hinged to a connecting rod 3. Any two rotating frames and the connecting rod 3 form a parallelogram mechanism. The driving force of the parallelogram mechanism is input from the leftmost rotating frame 2, and the power source is a driving cylinder 4. The rotating frame 2 is round rod-shaped, rotatably mounted on the main frame 1 at one end, with the other end freely extending. The rotating frames 2 are spaced apart and extend in the same direction. The rotating frame 2 is hinged to the connecting rod 3 via ear-shaped protrusions 5 fixed on its circumference. The end of the ear-shaped protrusion 5 of the leftmost rotating frame 2 is hinged to the piston of the driving cylinder 4. The cylinder body of the driving cylinder 4 is hinged to the main frame 1. In this way, the rotating frame and the driving cylinder form a crank-slider mechanism, with the slider providing power. A transverse roller 6 is provided on the main frame 1 between each pair of adjacent rotating frames 2. The two ends of the transverse roller 6 extend towards the two adjacent rotating frames 2. The transverse roller is rotatably mounted on the main frame 1; otherwise, it cannot function as a roller. An upper roller 7 is rotatably mounted on the upper part of the rightmost rotating frame 2, and a lower roller 8 is rotatably mounted on the lower part of the leftmost rotating frame 2. The upper and lower parts of the remaining rotating frames 2 are respectively rotatably mounted with an upper roller 7 and a lower roller 8. The extension direction of each upper roller 7 and lower roller 8 is the same as the extension direction of the rotating frame 2. A slanted roller 9 is rotatably mounted on the leftmost rotating frame of each pair of adjacent rotating frames 2. The upper part of the slanted roller 9 is close to the main frame 1, and the lower part is away from the main frame 1. The slanted roller 9 is to the right of the lower roller 8 on the same rotating frame. That is, the slanted roller on the same rotating frame is on the right side.

[0018] Specifically, each upper roller 7 and lower roller 8 is rotatably mounted on the rotating frame 2 via two ear plates 10. The ear plates 10 are fixed to the rotating frame 2, and the upper roller 7 and lower roller 8 are rotatably mounted on the two ear plates 10.

[0019] Specifically, the inclined roller 9 is assembled on the rotating frame 2 via an inclined column 11 fixed on the rotating frame 2. The upper end of the inclined column 11 is fixed on the rotating frame 2, and the inclined roller 9 is rotatably assembled on the side of the inclined column 11 close to the main frame 1.

[0020] The rotating frame in the above embodiment is a round rod, which is a specific structure. In other embodiments, it can also be a polygonal rod or an irregular structure.

[0021] In the above embodiment, the rotating frame is hinged to the connecting rod by an ear-shaped protrusion fixed on the circumference. In other embodiments, as long as a parallelogram structure can be formed, it is acceptable.

[0022] The above embodiments provide specific component installation methods. In other embodiments, any installation method in the prior art can be used as long as the installation function can be achieved.

[0023] The above embodiment uses a slanted roller on one side and a transverse roller on the other side. The two rollers do not act on the guide rod at the same time, so as not to cause damage to other structures due to jamming of the guide rod assembly. In addition, the guide rod has a relatively large straightening range.

[0024] The above embodiment uses five rotating frames; in other embodiments, the number of frames may be adjusted as needed.

[0025] Finally, it should be noted that the above embodiments are only for illustration and not for limiting the technical solutions of this utility model. Any equivalent substitutions and modifications or partial substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of protection of the claims of this utility model.
