Problems solved by technology

When wrapping the FRP protective layer of the pipe pile, it is necessary to meet the requirements that the rotational speed of the pipe pile reaches 1.3m / s, the fulcrum roller cannot cause crushing damage to the surface of the concrete pipe pile, and the axial movement of the pipe pile is not allowed during the rotation process. , but at present, the rotating equipment at home and abroad is the "rotary tire" used for pipe pile welding to adjust the position. This kind of equipment uses a group of four rollers as the fulcrum to support the pipe pile. Since there are many active rollers on it, it is easy to cause The layout is cumbersome and asynchronous, so the device cannot meet the technological requirements of wrapping the glass fiber reinforced plastic protective layer around the giant concrete pipe pile.

Embodiment Construction

[0024] Such as Figure 1 to Figure 5 As shown, the heavy-duty concrete pipe pile rotating device wrapped with a fiberglass protective layer provided by the present invention is mainly composed of a motor 1, a transmission belt 2, a reducer 3, a cardan shaft 4, a connecting hoop 5 and two limiting hoops 6, 6' The output shaft of the motor 1 is connected with the input shaft of the reducer 3 through the transmission belt 2; the output shaft of the reducer 3 is connected with one end of the cardan shaft 4, and the other end of the cardan shaft 4 is connected with the concrete The connecting hoop 5 outside one end of the pipe pile 7 is connected; two limit hoops 6, 6' are arranged in parallel at both ends of the glass fiber reinforced plastic protective layer 8 outside the concrete pipe pile 7. The connecting hoop 5 is mainly composed of two semicircular snap rings 9, rubber pads 10, end panels 11 and four pressure plates 12; the joints of the two semicircular snap rings 9 are for...

Abstract

The present invention is rotary apparatus and method for winding protective GRP layer to make heavy concrete pipe pile. The apparatus includes mainly motor, conveying belt, reducer, cardan shaft, connecting hoop and two-limit hoop connected together. The apparatus rotates pipe pile with its end axial driving system synchronously; there are rubber cushions set between each of the hoop and pipe pile to prevent damage of the pipe pile; and the two-limit hoop fixed onto the pipe pile makes the axial force the roller produces first absorbed by the track, then counteracted by the friction between the track and the pipe pile and transmitted to roller via the track to avoid the axial shift of the pipe pile.

Description

technical field [0001] The invention relates to a preparation device and method for building engineering foundation components, in particular to a heavy-duty concrete pipe pile rotating device and method for wrapping a fiberglass protective layer. Background technique [0002] The container terminal is a terminal specially built for loading, unloading and storing containers with the development of waterway container transportation. According to the design requirements, when building this type of wharf, it is necessary to connect giant hollow concrete pipe piles with a length of 25-32m, an outer diameter of 1.2m, and a weight of 32-42 tons to 60m and then drive them into the seabed. Therefore, it is necessary to wrap some concrete pipe piles with a length of 16-18m in seawater with a glass fiber reinforced plastic protective layer to resist the corrosion of seawater on concrete materials. When wrapping the FRP protective layer of the pipe pile, it is necessary to meet the re...
