Description

Technical Field

[0001] The invention relates to the technical field of automatic assembly equipment for bolts and nuts, and in particular to automatic assembly equipment for tower foot bolts and nuts. Background Art

[0002] In the field of power transmission towers, it is generally necessary to dig a pit and bury the mixed concrete. After the concrete solidifies, the tower foundation is formed, and then the tower is fixed to the tower foundation. The connection between the tower and the tower foundation is generally carried out in the following way: a tower foot plate is set at the bottom of the tower, and then the tower foot plate is installed on the tower foot bolts, wherein the tower foot bolts are preset in the tower foundation, and a foundation plate is buried inside the tower foundation. After the foundation plate and the bottom thread of the tower foot bolt are fixed, concrete is filled in to ensure that the tower foot bolts are firmly connected to the tower foundation.

[0003] Currently, to facilitate the installation of tower foot bolts and their subsequent attachment to the tower foot plate, manufacturers mostly manually assemble the tower foot bolts and nuts, then transport them in batches to the construction site. Workers then use the nuts at the ends of the tower foot bolts to assemble and secure them to the foundation plate. Concrete is then filled in, and after the concrete solidifies, the nuts at the top of the tower foot bolts are used to assemble and secure them to the tower foot plate. This method ensures that the number and specifications of nuts match the tower foot bolts, preventing insufficient or mismatched nuts from impacting the construction process. However, manual assembly of tower foot bolts and nuts is inefficient and cannot achieve continuous automated production, hindering the construction process. Furthermore, workers working long hours can lead to fatigue and errors, which can cause problems such as missing nuts and tower foot bolts.

[0004] Therefore, we make improvements to this and propose an automatic assembly equipment for tower foot bolts and nuts. Summary of the Invention

[0072] Working principle of the present invention:

[0073] Several tower foot bolts are arranged horizontally at the end of the guide plate 31 of the loading rack 3. Under the action of the discharge surface 32, a single tower foot bolt at the front is placed on the upper part of the push plate B34 at the rear of the guide plate 31. All cylinders B33 of the guide plate 31 are started synchronously, pushing and retracting the push plate B34 in a cycle. Under the push of the push plate B34, the tower foot bolts are pushed one by one in the direction from the end to the front of the loading rack 3 to the discharge surface 32 at the front end of the loading rack 3, thus realizing the loading of the tower foot bolts.

[0074] The tower foot bolt placed at the front end of the loading rack 3 enters the groove of the conveying wheel 6 under the action of the unloading surface 32 and its own gravity. The hydraulic cylinder A9 drives the positioning wheel 7 to move downward, and the upper parts of the two ends of the tower foot bolt enter the groove of the positioning wheel 7, thereby realizing the horizontal positioning and longitudinal fixation of the tower foot bolt. The conveying wheel 6 drives the tower foot bolt to move horizontally, so that the two ends of the tower foot bolt move to the conveying screwing parts 2 at both ends of the conveying positioning part 1;

[0075] Several nuts are placed on the upper part of the feed plate 23 in the inner cavity of the conveying screw-on component 2. Under the action of the feed plate 23, the nuts gather on the upper part of the push block 11. The hydraulic cylinder B15 pushes the push block 11 upward, pushing the nuts on the inclined surface of the push block 11 head onto the conveying platform 12. The conveying platform 12 drives the nuts to move toward the guide groove plate 13.

[0076] The screening plate 24 can screen the placement status of the nuts. The nuts in the horizontal state enter the guide groove plate 13 through the screening groove 25, and the nuts in the upright state are blocked by the screening plate 24. Under the oblique placement of the screening plate 24 and the conveying action of the conveying platform 12, the nuts in the upright state return to the upper part of the feeding plate 23 through the return groove 26;

[0077] The nut dropped into the guide groove plate 13 by the front end of the conveying platform 12 is in a vertical state, and then slides into the screwing assembly 14 in the guide groove plate 13. The positioning adjustment plate 20 adjusts the position of the semi-annular arc plate 21 so that the axis of the tower foot bolt and the nut coincide. The screwing motor 17 is started to drive the nut to rotate. At the same time, the conveying wheel 6 drives the tower foot bolt to move toward the nut. After being squeezed by the tower foot bolt, the rotating nut is screwed into the tower foot bolt.

[0078] After the nut at one end of the tower foot bolt is screwed in, the conveying wheel 6 drives the tower foot bolt to move toward the conveying screwing component 2 at the other end of the conveying positioning component 1, and screws the other end of the tower foot bolt into the nut;

[0079] After the tower foot bolts and nuts are assembled, the hydraulic cylinder A9 drives the positioning wheel 7 to rise, and the cylinder A29 drives the push plate A30 to rise. The push plate A30 pushes the tower foot bolts out of the groove of the conveying wheel 6. The inclined structure of the push plate A30 pushes the tower foot bolts toward the guide rod 35 at the upper front end of the unloading rack 4, and then the tower foot bolts slide down to the upper part of the unloading rack 4 by the guide rod 35.

[0080] Then repeat the above steps in a cycle to realize the automatic cycle work of assembling the tower foot bolts and nuts.

[0081] In addition, it should be pointed out that the tower foot bolt is laterally moved by the conveying wheel 6 and cooperates with the conveying screwing component 2, so that the end of the tower foot bolt can be screwed with multiple nuts.
