Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated beam prestressing tensioning, and specifically relates to a material storage tank-free type steel strand cutting, bundling and bundle threading integrated equipment. Background Art

[0002] Prestressing is a very important part of precast beams. Precast beam tensioning refers to applying prestressing stress to the steel strands in the tension beam body to improve the bending resistance and rigidity of the component, delay the time for cracks to appear, and increase the durability of the component; but before tensioning, the finished steel strands need to be processed and bundled into the beam body. At present, most beam yards still use manual processing, cutting, bundling, and bundling of steel strands. The construction efficiency is low, and the unloading and weaving process of steel strands is slow. The quality of the finished product is unstable and cannot achieve the expected effect. Although automatic unloading and weaving equipment has been developed on the market, it can only be operated in a single position and cannot be moved. If the steel strands are stored in storage tanks, they still need to be cut and transported manually in advance, with a low degree of mechanization and low efficiency.

[0003] In summary, it is necessary to develop a mobile, easy-to-load and unload, reusable, more mechanized, and tank-free bridge prestressed steel strand automatic unloading, bundling, and bundle threading mobile integrated equipment. Utility Model Content

[0007] The lifting workbench is installed on the template trolley, and the lifting workbench is arranged in sequence with steel strand combing, steel strand rotating and pushing mechanism and steel strand cutting mechanism; after the steel strands of multiple steel strand drums are unfolded, they are passed through the steel strand combing, steel strand rotating and pushing mechanism and steel strand cutting mechanism in sequence and finally penetrated into the prefabricated beam; the steel strand rotating and pushing mechanism is equipped with a steel strand binding unit.

[0008] Furthermore, the lifting workbench includes a supporting platform, an X-shaped hinged lifting arm, a base frame and a top supporting component; the base frame is installed on the template trolley, the lower end of the X-shaped hinged lifting arm is connected to the base frame through a lower hinge node and a lower sliding node, and the upper end supports the supporting platform through an upper hinge node and an upper sliding node, and the top supporting component is installed between the template trolley and the lower sliding node. The top supporting component pushes the lower sliding node to slide, thereby changing the angle of the X-shaped hinged lifting arm, and the steel strand combing arrangement, steel strand rotation pushing mechanism and steel strand cutting mechanism are on the supporting platform.

[0009] Furthermore, the supporting component is a hydraulic cylinder.

[0010] Furthermore, the top surface of the ferry trolley is provided with two longitudinal rails, and the longitudinal rails are I-beams.
