[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe clamp device for hydraulic piping, which is mainly provided in construction machines, working machines, industrial machines and the like.

[0002]

2. Description of the Related Art FIG. 6 is a side view of a dismantling machine for dismantling structures such as buildings. In the figure, reference numeral 1 denotes a hydraulic excavator body (hereinafter, referred to as hydraulic excavator 1) which is a construction machine;
Is a two-piece long attachment attached to the front part of the excavator 1, 3 is a main boom, 4 is a rear boom of the main boom 3, 5 is a front boom, 6 is an arm, 7 is a crusher, 8, 9, and 10 are Each is a hydraulic cylinder. FIG. 7 is a main part rear view of the rear boom 4 in FIG. In the figure, 12, 13, 14,
Reference numeral 15 denotes a pipe for hydraulic piping, and reference numerals 16 and 17 denote conventional pipe clamp devices. FIG. 8 is a diagram showing the structure of the pipe clamp device 16 as viewed from the line BB in FIG. In the drawing, reference numerals 18 and 19 denote a holding member and a block with a screw hole, respectively, which are clamp members, reference numeral 20 denotes a bolt, and reference numeral 21 denotes an arc-shaped fastening groove formed on the lower surface side of the holding member 18. FIG. 9 is a view showing the structure of the pipe clamp device 17 as viewed from CC in FIG. In the drawing, reference numerals 22 and 23 denote a holding member and a block with a screw hole, respectively, which are clamp members, 24 denotes a bolt, and 25 denotes a holding member 2.
2 is an arc-shaped fastening groove formed on the lower surface side of FIG. FIG. 10 is a perspective view of the pipe clamp device 17 in FIG.

As shown in FIGS. 8 and 9, in the prior art pipe clamping devices 16 and 17, a single pipe (12) is used.
Alternatively, the plurality of pipes (14, 15) are sandwiched between a pair of clamp members (the presser fitting and the block with a screw hole are referred to as a pair of clamp members). Since the strength of the pipe clamp device 17 for a plurality of pipes (14, 15) is set to be larger than that of the pipe clamp device 16 for a single pipe 12, the shape and dimensions of each component are all large. For example, the screw diameter M2 of the bolt 24 is larger than the screw diameter M1 of the bolt 20.

When the dismantling machine equipped with the two-fold long attachment 2 shown in FIG. 6 performs dismantling work of a huge object structure (not shown), it may be changed to a three-fold long attachment. is there. FIG.
FIG. 4 is a side view of the dismantling machine which has been replaced with a three-fold type long attachment 2 ′. In the figure, 26 is an inter-boom, 27 is a long arm, and 28 is a jib cylinder. Since the three-fold long attachment 2 'requires the jib cylinder 28, the hydraulic piping of the jib cylinder 28 and a large number of pipe clamp devices (not shown)
Was added to the main boom 3. The trouble was troublesome and required a great deal of time and effort. When the three-bend long attachment 2 'is replaced with the two-bend long attachment 2, the hydraulic piping for the jib cylinder (28) is removed. Was. An object of the present invention is to provide a pipe clamp device that can solve the above problems.

[0005]

Means for Solving the Problems A pair of clamp members,
A tightening groove formed in at least one of the pair of clamp members, a pipe fitted into the tightening groove and clamped and fixed by the pair of clamp members, and a tightening groove when the pipe is removed. A bar piece which is fitted into the groove and is clamped and fixed by the pair of clamp members. The bar piece has substantially the same outer diameter as the pipe and is substantially equal to the length of the tightening groove. Formed in length.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows the pipe clamp device 29 of the present invention.
FIG. 3 is a diagram showing the structure of FIG. In the figure, reference numerals 30 and 31 denote a clamp and a block with a screw hole, respectively, which are clamping members
32 is a bolt, 33 is a bar piece, 34 and 35 are arc-shaped tightening grooves formed on the lower surface side of the presser fitting 30, respectively.
Reference numeral 1 denotes an outer diameter of the pipe 12 (the same reference numerals are used because the pipe clamp device 29 is applied to the conventional pipe 12), and d2 denotes an outer diameter of the bar piece 33. FIG. 2 is a perspective view of the bar piece 33 in FIG. When the bar piece 33 is tightened as shown in FIG. 1, the outer diameter d'2 of the intermediate outer peripheral portion c is reduced to a diameter slightly smaller than d2 so that the outer peripheral portions a and b at both ends are securely tightened. Processing. The dimension l1 is the bar piece 3
3 is the total length. FIG. 3 is a perspective view of the pipe clamp device 29 in FIG. In the figure, the dimension l2 is the length of the fastening groove 35, and this length l2 is the same as the width dimension of the holding member 30.

Next, the structure and operation of the pipe clamp device 29 of the present invention will be described with reference to FIGS. In the present invention, a bar piece 33 having a length substantially equal to the length l2 of the tightening groove 35 is fitted into the tightening groove 35 with respect to the tightening groove 35 formed in the holding member 30 as a clamp member. so,
It was configured to be clamped between the screw hole block 31 and the presser fitting 30. Thus, for example, when replacing a long attachment of a construction machine, when it is desired to increase the number of hydraulic pipes, the bar piece 33 sandwiched between the screw hole block 31 and the holding metal fitting 30 is replaced with the bolt 32. Unscrew, remove and store. Then, the hydraulic pipe to be increased can be tightened at the position where the bar piece 33 is removed. When the long attachment is replaced again and the hydraulic pipe is removed for use, the pipe clamp device 29 can be maintained by attaching the stored bar piece 33. The outer diameter d of the bar piece 33
2 may be set to be substantially the same as the outer diameter d1 of the pipe 12, but if the outer diameter of the pipe to be attached and removed is slightly different from the outer diameter d1 of the pipe 12, the shape of the tightening groove 35 It may be formed by adjusting the dimensions.

8 is a holding bracket and a block with a screw hole, respectively, 39, 39
Is a bolt, and 40, 41, and 42 are bar pieces. In this pipe clamp device 36, a plurality of bar pieces 4 (hydraulic piping) can be added.
0, 41 and 42 are attached. The operation and function of the pipe clamp device 36 are the same as those of the pipe clamp device 29 shown in FIGS.

FIG. 5 is a view showing the structure of a pipe clamp device 43 according to another embodiment of the present invention. In the figure, 4
4 and 45 are upper and lower holding brackets respectively, 46 is a board,
47 and 47 are bolts, and 48 is a plurality of bar pieces.
There are various types of pipe clamp devices for hydraulic piping, and the pipe clamp device 43 is one of them. A plurality of bar pieces 48 can be attached to this pipe clamp device 43 as well. The operation and function of the pipe clamp device 43 are the same as those of the pipe clamp device 29 shown in FIGS.

[0010]

According to the prior art, when a two-fold long attachment attached to a dismantling machine is replaced with a two-fold long attachment, hydraulic piping for a jib cylinder is required. Was added to the main boom. The trouble was troublesome and required a great deal of time and effort. When the jib cylinder hydraulic pipe is not used when it is removed, the pipe clamp device cannot be accommodated. However, in the pipe clamp device of the present invention,
For example, when replacing the long attachment of construction equipment and want to increase the number of hydraulic piping,
Remove and store the bar piece attached to the pipe clamp device of the present invention. Then, the hydraulic pipe to be increased can be tightened at the position where the bar piece is removed. Further, when the long attachment is replaced again and the hydraulic pipe is removed for use, the pipe clamp apparatus can be maintained by attaching the stored bar piece. Therefore, by attaching the pipe clamp device of the present invention to a construction machine, a working machine, or an industrial machine corresponding to a work by attaching and removing a pipe such as a hydraulic pipe, the economic effect can be exhibited and the maintainability can be improved.
