Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated components, in particular to a tarpaulin laying combing machine. Background Art

[0002] Compared with ordinary concrete composite slabs, prestressed concrete composite slabs have the characteristics of high crack resistance, large bearing capacity, large span and material saving. At present, prestressed concrete composite slabs are generally produced using long-line formwork, but since the long-line formwork is generally about 130 meters long, the length of the prestressed tendons used is also about 120 meters. The existing prestressed tendons need to be placed in the correct position before tensioning, and the placement work is generally done by workers manually. However, since the length of the prestressed tendons is too long, the workers need to spend a lot of time to adjust the position of the prestressed tendons, which affects the production efficiency of the prestressed concrete composite slabs; at the same time, before the initial setting of the prestressed concrete composite slabs, tarpaulins need to be laid on them to play a role in maintenance, but the existing tarpaulin laying and rolling work is generally done by hand, and the workers have high labor intensity, which further reduces the production efficiency of the prestressed concrete composite slabs. Utility Model Content

[0003] The purpose of the utility model is to provide a tarpaulin laying and combing machine, which drives a combing and hair pulling component and a tarpaulin retracting and releasing component by driving a trolley. The combing and hair pulling component can comb large-span prestressed tendons, and the tarpaulin retracting and releasing component can automatically complete the laying or winding work of the tarpaulin, which can effectively reduce the labor intensity of workers and effectively improve the production efficiency of prestressed concrete composite panels.

[0006] Through the above technical scheme, the driving trolley can drive the bar combing and roughening assembly and the tarpaulin retracting and releasing assembly to move on the prestressed long-line formwork platform; with the movement of the bar combing and roughening assembly, the prestressed bars placed on the prestressed long-line formwork platform can be combed, so that multiple prestressed bars are arranged in parallel with equal spacing; the roughening assembly can roughen the concrete on the prestressed long-line formwork platform, so that the surface of one side of the obtained prestressed component is rough; and the tarpaulin retracting and releasing assembly can lay a layer of tarpaulin on the roughened concrete surface, so that the combing of the prestressed bars, the roughening of the concrete, and the laying and rolling of the tarpaulin can be quickly completed when casting the prestressed prefabricated components;

[0007] The driving trolley is detachably connected with the bar-combing and napping assembly and the tarpaulin retracting and releasing assembly.
