Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a movable sheet winding machine for curing sheets used in constructions affected by rain such as civil engineering works.

[0002]

2. Description of the Related Art Conventionally, laying and removal of a curing sheet are performed manually. Therefore, a large sheet (for example, 3
(0m × 30m), it takes 2 hours for about 10 people.

[0003] In addition, a large number of people fold the product several times and transport it to a material storage place so that it can be transported manually, which is troublesome.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a movable sheet winding machine which saves labor for laying and removing a curing sheet and facilitates transportation.

[0005]

According to the present invention, a frame mounted along a blade of a bulldozer, hydraulic motors mounted at both ends of the frame, and removably connected to drive shafts of these hydraulic motors. And a winding cage around which the curing sheet is wound.

The hydraulic source of the bulldozer body is used as the hydraulic source of the hydraulic motor.

In the mobile sheet winder constructed as described above, when the curing sheet is laid, the edge of the curing sheet is fixed to the edge of the laying surface, and the winding cage is unwound by a hydraulic motor. The bulldozer moves backward while rotating in the direction. At the time of removal, the above operation is performed in the reverse order.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, a frame 5 is provided along a top edge of a bulldozer blade 2 indicated by reference numeral 1 via a pair of stanches 3 and stays 4. At both ends of the frame 5, hydraulic motors 6, 6 using a hydraulic source (not shown) of the bulldozer 1 as a hydraulic source are provided, respectively, so that the bulldozer 1 can be operated independently.

Referring also to FIGS. 3 and 4, a take-up cage generally indicated by reference numeral 10 is detachably connected to the drive shafts 7 of both hydraulic motors 6. The cage 10 is formed of a hexagonal column-shaped cage main body 11, and a driven shaft 12 is provided at both ends. At the end of the driven shaft 12, a half portion 13 is formed which engages with the half portion 8 of the drive shaft 7, and a sleeve 9 for selectively connecting the two portions 8 and 13 is movably provided. Not to be locked with a set screw.

Next, the manner of laying and removing the curing sheet S will be described mainly with reference to FIG.

First, the blade 2 is lowered and the hydraulic motor 6
Of the cage 10 is engaged with the half 13 of the cage 10, the sleeve 9 is moved in the direction A, the two are connected, and the winding cage 10 on which the curing sheet S is wound is locked and the bulldozer 1
Set to. In addition, the sheet S is stored in the cage 1 in advance.
Instead of being wound around zero, the cage 10 may be driven and wound each time, or may be wound around the cage 10 by another device. At the time of laying, the cage 10 is moved to near the edge of the laying surface G via the blade 2. Therefore,
The edge of the sheet S is fixed with a fixing pin P. Next, the cage 10 is rotated in the unwinding direction C by the hydraulic motors 6, and the bulldozer 1 is moved backward, that is, in the unwinding movement direction E, to lay the sheet S. At this time, care is taken so that tension is not applied to the sheet S. The unevenness of the laying surface G is controlled by controlling the attitude of the blade 2 by a known operation of the bulldozer 1.

At the time of removal, contrary to the above, the bulldozer 1 is moved forward, that is, moved in the winding movement direction F, the cage 10 is moved in the winding direction D, and the sheet S is wound on the cage body 11.

When transporting, the bulldozer 1 is moved to the material storage area in the above state, the cage 10 is lowered to the floor, the sleeve 9 is moved in the direction B, and the connection between the two halves 8, 13 is released. Move the bulldozer 1.

[0015]

Since the present invention is constructed as described above, the laying and removal of the curing sheet can be omitted by mechanization.

Further, the curing sheet can be easily transported by a bulldozer.
