Lead screw end position limiting and cushioning structure

PendingCN122589953Aprotection from destructionNo need to increase size
This invention belongs to the field of lead screw transmission technology and discloses a lead screw end limiting and buffering structure, including a lead screw and a limiting and buffering device. The limiting and buffering device is located at the end of the lead screw. When the nut on the lead screw moves to the end of the lead screw, the limiting and buffering device first limits the axial and rotational movement of the nut. When the limiting torque set by the limiting device is exceeded, the limiting device fails, thereby buffering. The buffer is located between the fixed part and the rotating part. The closer the distance between the fixed part and the rotating part, the greater the force exerted by the buffer on the rotating part. During normal operation, this invention achieves a reliable mechanical limiting function through the limiting pin, with high limiting accuracy. Under abnormal impact conditions, the limiting pin fails at the set torque threshold, limiting the peak instantaneous impact load below the set value, effectively protecting the lead screw, nut, and other structural components from damage, and avoiding the problem of excessive impact load generated by rigid limiting structures.

Limiting structure for precise installation of steel pipe column and pile foundation

ActiveCN224092723UGuaranteed verticalityHigh limit accuracyStrutsFoundation engineeringArchitectural engineeringRebar
The utility model relates to the technical field of steel pipe columns, and discloses a limiting structure for accurate installation of a steel pipe column and a pile foundation, which comprises a limiting seat arranged on a steel bar frame of the pile foundation and used for limiting a plurality of foundation bolts, the lower parts of the foundation bolts penetrate into and are fixed in the pile foundation to form a fixed section, and the fixed section is fixed on the limiting seat. The upper portion of the foundation bolt extends to the position above the pile foundation to form a connecting section connected with the steel pipe column. A plurality of lower holes allowing the connecting sections to penetrate through are formed in the lower portion of the limiting seat, a plurality of upper holes allowing the connecting sections to penetrate through are formed in the upper portion of the limiting seat, the lower holes and the upper holes are formed in the circumferential direction of the limiting seat in a surrounding mode at intervals, and the upper holes and the lower holes are formed in an up-down longitudinal alignment mode; upper and lower two-layer positioning is formed by using the upper hole and the lower hole, so that the perpendicularity of the foundation bolt is ensured, and the limiting precision is high.
