Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention will be further described with reference to the following embodiments.
The small-sized trolley for dismounting the template in the tunnel comprises a trolley main frame 1, telescopic parts 2 and a template 3, wherein the trolley main frame 1 is in an arch shape, the template 3 is divided into seven units, the units are paved on the periphery of the trolley main frame 1 in turn, the unit templates 3 are connected through hinges 4, the telescopic parts 2 are installed between the trolley main frame 1 and the template 3, the telescopic parts 2 are fixed between the templates 3 of the seven units and the trolley main frame 1, the telescopic parts 2 are hydraulic machines, tails of the hydraulic machines are fixed on the trolley main frame 1, telescopic machine rods are fixed on the templates 3, and the template 3 reaches a designated position through the contraction work of the hydraulic machines. The unit manufacture and material selection of the template 3 are combined with domestic and foreign templates, a high-strength plastic template is selected, the template 3 has translucency, the concrete pouring position can be seen visually, and the concrete pouring symmetry is guaranteed.
Specifically, the trolley main frame 1 comprises a horizontal underframe 10 made of 14# I-steel, vertical frames 11 perpendicular to the left side and the right side of the horizontal underframe, and an arch frame 12 transversely erected at the top of the vertical frames 11, wherein the width of the arch frame 12 is wider than the distance between the two vertical frames 11, and telescopic spaces of the formworks 3 on the two sides are reserved. Considering the convenience of processing and contraction of the template 3, the template 3 is divided into seven units for processing, each unit is connected by a hinge, the first unit 1D, the second unit 2D, the sixth unit 6D and the seventh unit 7D of the template are rectangular and fixed outside the vertical frame 11 through the telescopic part 2, and the third unit 3D, the fourth unit 4D and the fifth unit 5D of the template 3 are arc-shaped and are sequentially spliced above the arch frame 12.
