Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a gutter member reversing device.

(Prior art) Conventionally, U-shaped grooves have been used as side gutter members for constructing drainage channels and irrigation canals, but in recent years U-shaped grooves have been used as side gutter members for constructing drainage channels and irrigation canals.
(Variable 5lope) A side gutter member 10 called a side gutter has come into use. This VS
Gutter III is a side gutter member 10 with a gate-shaped structure, and can be formed by simply pouring cast-in-place concrete at the open bottom, and the opening on the top surface 12 is covered with a grating. .

The gutter member 10 is formed by pouring concrete into a mold. At that time, since the upper surface of the gutter member IO is required to be formed into a smooth surface, the molding frame 16
As shown in FIG. 2, a concrete is used which is provided with a space 14 having a U-shaped cross section, and concrete is poured into this space 14 and allowed to harden. After concrete hardens, formwork 1
Just remove 6. However, in this state, the top surface 12 of the side gutter member 10 faces downward, and it is necessary to turn it over so that the top surface 12 faces upward, for example, for transportation to the installation site or shipping. There are methods in which a worker pushes the member IO and transfers it, and a method in which the member IO is hoisted up by a crane, turned over in the air, and then lowered to the ground.

(Problem B to be Solved by the Invention) However, the conventional method of inverting a gutter member has the following problems.

The method of transferring workers by pushing them by hand requires a large area for transfer. Moreover, if the object is heavy, a large number of workers will be required, resulting in poor work efficiency. In addition, the method using a crane requires a large space for lifting and reversing the gutter member with the crane. Furthermore, since turning over the gutter member in the air is performed by a worker, it is a very dangerous work and there is also the problem of poor efficiency.

Therefore, an object of the present invention is to provide a gutter member reversing device for safely and efficiently reversing gutter members.

(Means for solving problems) In order to solve the above problems, the present invention has the following configuration.

That is, a frame, a drum having a cylindrical shape, supported rotatably around an axis relative to the frame, and having a housing section therein for housing a gutter member, and an interior of the housing section of the drum. In order to hold the gutter member in the
The drum is provided with one or more pairs of clamping members that can move toward and away from each other, a mechanism for moving the clamping members toward and away from each other, and a rotation mechanism for rotating the drum. It is characterized by

(effect) The effect will be explained.

When the side gutter member is clamped by the pressure member within the housing portion of the drum and the tram is rotated in half by the rotating mechanism, the side gutter member can be reversed safely and efficiently.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, the configuration will be explained.

FIG. 3 shows a front view of the reversing device 18, and FIG. 4 shows a side view thereof.

Reference numeral 20 denotes a frame, which includes a beam 22 serving as a base and a stopper 24 erected on the beam 22.

and is pivotally supported by a support member (not shown). However, the axis 54
is not connected to a driving means such as a motor. In addition, the above-mentioned motor 50, rollers 34, 36, 38, and rail 30
, 32, etc. constitute a rotation mechanism for rotating the drum 28 with respect to the frame 20. Rotation of the motor 50 therefore rotates the rollers 34.36, which frictionally engage the rails 30.32, thereby causing the drum 28 to rotate about its axis. At that time, the free roller 38 and a roller (not shown) rotate while the drum 2
It is designed to assist the rotation of 8.

58 are protrusions that come into contact with the bushes 26 of the stoppers 24 to regulate the amount of rotation of the drum 28.

Reference numerals 60 and 62 denote pinching members, which clamp or release the pinching of the side gutter member 10 by moving toward and away from each other at the same speed within the housing portion 40 by a contacting and separating mechanism to be described later. Furthermore, rubber plates 64 and 66 for protecting the gutter member 10 are attached to both opposing surfaces of the pinching members 60 and 62.

In addition, 68 is a carrying-in conveyor, and is a means to feed the gutter member IO into the storage part 40 (in the direction of the arrow). On the other hand, 70 is a carry-out conveyor, which is means for sending out the reversed side gutter member 10 from the storage section 40 (in the direction of arrow B).

Next, the internal structure will be explained with reference to FIG.

72 are rollers that feed the side gutter member 10 sent by the carry-in conveyor 68 into the storage section 40, or transport the side gutter member 10 in the storage section 40 to the general output conveyor 70.
It is provided to assist when sending out.

74 are guides that guide the vertical movement of the clamping portions 60, 62 of the drums 28. There are four inside.

The clamping members 60, 62 are fixed to sleeves 76, which are slidably engaged with guides 74, .

78... is a sprocket, which is rotatably attached to the inner wall of the drum 28, and the chain 80... is spanned over, and the clamping member 60 is connected to the chain 80... by the connection member 82, 84.
..., and on the other hand, the clamping member 62 is also connected to the chain 80... by connecting members 86, 88.

By connecting the clamping member 60.62 to the chain 80... by the connecting member 82.84.86.88 in this aspect,
When the chain 80... is driven, the pinching members 60, 62
It is possible to make contact and separation movements at the same speed.

90 is a cylinder device in which a pneumatic cylinder is used;
The tip 94 of the rod 92 is fixed to the clamping member 60, and the lower end is fixed inside the drum 28. Therefore, the clamping member 60 moves up and down due to the expansion and contraction of the rod 92, and as a result, the chains 80... are driven. The guide 74 mentioned above
..., sprocket 78..., chain 80...
, cylinder device 90, etc. constitute a mechanism for moving the clamping members 60, 62 toward and away from each other. In addition, in the case of this embodiment, the pinching member 6
The strokes of 0.62 extend to positions 60a and 62a indicated by two-dot chain lines in FIG. 5, respectively.

Next, the operation of the reversing device configured as described above will be explained with reference to FIG. 6.

First, the side gutter member 10, which has been taken out of the formwork 16 and whose upper surface 12 is facing down, is sent from the carry-in conveyor 68 into the housing portion 40 of the drum 28 (the state shown in FIG. 6(a)). Next, pressure is applied to the cylinder device 90 in order to shorten the rod 92 of the cylinder device 90, in which the rod 92 was previously in an extended state (initial position). Then, the tip of the rod 92 is drawn into the cylinder device 90, and the clamping member 60 moves to the center accordingly.

At this time, since the pinching member 62 also moves toward the center at the same speed via the contact/separation mechanism, the side gutter member 10 rises to the center of the housing portion 40 and is pinched by the pinching members 60, 62. In this embodiment, the cylinder device 90 is pressurized until the pressure reaches 5 kg (as shown in Figure 6(b)!3). Nipping member 60
．． 62 firmly clamps the gutter member 10, the motor 50
is rotated, and the rotation mechanism such as the rollers 34, 36, 38 is driven to rotate the drum 28 by 180° in the direction of arrow C (the state shown in FIG. 6(C)). Projection portion 58a of drum 28
When it comes into contact with the stopper 24a, the rotation mechanism is stopped and the rod 92 of the cylinder device 90 of the contact/separation mechanism is extended. Then, the clamping members 60 and 62 separate from each other at the same speed (the state shown in FIG. 6(d)). Then, when the rod 92 extends and reaches the initial position, the contact/separation mechanism is stopped (Fig. 6 (
e) condition).

When the lot 92 reaches the initial position and the descent of the side gutter member 10 is completed, the side gutter member 10 may be sent onto the carry-out conveyor 70. The next reversal of the gutter member IO can be done by rotating the motor 50 in the opposite direction to rotate the drum 28 in the direction opposite to arrow C, so there is no need to take the trouble of reversing the drum 2 and returning it to its original state for the next reversal. (It is efficient.

In other embodiments, both of the clamping members 60, 62 do not necessarily have to move toward and away from each other at the same speed, and one of the clamping members 60, 62 may be fixed. In that case, the height of the conveyor may be made variable, and the drum 28 may be reversed and returned to its original position before the next reversal. Further, the rotation direction of the drum 28 does not have to be two directions, and the stopper 24... and the protrusion part 58...
As long as the amount of rotation of the drum 28 can be accurately controlled without providing the structure, the drum 28 may be configured to rotate only in one direction.

Moreover, the clamping member may be clamped not only in the vertical direction but also in the horizontal direction of the side gutter member 10 using a height-variable conveyor, or may be clamped in both the vertical and horizontal directions. Furthermore, the accommodating portion 40 does not necessarily have to penetrate the drum 28.

Although various preferred embodiments of the present invention have been described above, the present invention is not limited to the above-mentioned embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. It is.

(Effects of the Invention) When the gutter member reversing device according to the present invention is used, the area and space occupied for reversing are only the area and space occupied by the device, so the space factor is improved. In addition, only one operator is required to perform the reversal, and the work speed is increased, resulting in efficiency and economical effects. Furthermore, there is no need for manual work by the worker during the reversing operation, and there is no risk of danger, resulting in an outstanding safety feature.
