AI Technical Summary

Technical Problem

Existing concrete pouring equipment is cumbersome to install and dismantle, has low positioning accuracy, and is inconvenient to move, resulting in uneven concrete pouring, affecting structural strength, and consuming a lot of manpower and resources.

Method used

The system employs a quick-release mechanism, rollers, limit blocks, and a servo motor-driven limit rod. Through snap-fit ​​positioning and rolling guidance, it achieves rapid installation and precise positioning of the injection mechanism. Combined with an arc-shaped design and a rigid support structure, it ensures the stability and accuracy of the injection process.

Benefits of technology

It enables convenient disassembly and assembly and high-precision positioning of the grouting mechanism, improves construction efficiency, reduces manual adjustment time, and ensures the dimensional accuracy and quality of the engineering structure.

Abstract

The utility model relates to the technical field of tunnel engineering construction, in particular to a rear bottom plate assembly trolley which comprises a trolley mechanism, a quick release mechanism is arranged at the top of the trolley mechanism, and a pouring mechanism is arranged at the top of the quick release mechanism; by arranging the positioning table, the rolling shaft, the first limiting block and the second limiting block of the quick release mechanism and the portal frame, the limiting rod and other parts of the trolley mechanism, the bottom clamping block of the positioning table is matched with the top clamping groove of the portal frame in an inserted mode, and the rolling shaft is in rolling contact with a second sliding rail clamping groove of the pouring mechanism between the limiting blocks; a locking relation that a limiting rod is driven by a servo motor to ascend and descend to be inserted into a clamping groove is adopted, so that the quick dismounting mechanism can quickly mount and stably limit the pouring mechanism through clamping positioning and rolling shaft guiding, and the effect that the device can conveniently dismount and precisely position the pouring mechanism through a modularized quick dismounting structure is achieved; the construction efficiency is obviously improved; and the manual adjustment time is shortened.
