Description

  The present invention relates to a hose holding device for holding a plurality of hoses together in a construction machine such as a dismantling machine or a hydraulic shovel.

  Large construction machines are disassembled and transported into multiple sections due to legal restrictions, and are assembled at the destination.

  For example, a dismantling machine with an ultra-long attachment has a work attachment 4 attached to a self-propelled and revolving machine body (base machine) 3 composed of a lower traveling structure 1 and an upper revolving structure 2 as shown in FIG. Then, at the time of transportation, the machine body 3 and the work attachment 4 are separated.

  The work attachment 4 is also disassembled into a main boom 5 attached to the machine main body 3 (upper revolving unit 2) so as to be able to move up and down, and an insert boom 6 connected to the tip thereof. Sections (working devices such as a front boom, an arm, and a crushing device; not shown) are also disassembled as necessary.

  Here, in many cases, the main boom 5 and the boom cylinder 7 for raising and lowering the main boom are attached to an adapter 8 so that the main boom 5 can be disassembled / assembled in an integrated state. Has been taken.

  On the other hand, a plurality of hoses 9 as attachment pipes for connecting hydraulic actuators for operating the work attachments 4 and hydraulic equipment on the machine body 3 side are attached to the upper surface of the attachment (the upper surface in a state where it is tilted down as shown in FIG. The same is true of the vertical direction described above), and the machine body side end is connected to a fixed piping (not shown) routed to the machine body 3 in the machine assembled state.

  Hereinafter, the end of the hose 9 near the machine body 3 is referred to as a “base end”, and the opposite side is referred to as a “distal end”.

  Each hose 9 is divided into an attachment side hose 9a from the hydraulic actuator to the adapter 8 and a relay hose 9b from the adapter 8 to the fixed pipe, and both hoses 9a and 9b are connected to each other by projecting from the upper surface of the adapter 8. Connected by block 10.

  FIG. 12 shows a disassembled state in which the main boom 5, the boom cylinder 7, and the adapter 8 (hereinafter referred to as "main boom unit") are detached from the upper revolving unit 2 and the hose 9 is separated from the fixed pipe. In this state, the main boom unit is transported and attached to the machine body 3 at the destination.

  At the time of disassembling or assembling the unit, the base end side of the relay hose 9b hangs down toward the machine body due to its own weight as shown in the figure, and is caught by fixed pipes or structures or hinders the work, which hinders disassembly / assembly work. There was a case to come.

  In addition, hoses routed on the upper surface of the insert boom 6 of each stage, hoses (not shown) routed across the front boom and the inter-boom, etc., also hang down while being separated from the adjacent hoses, A similar problem had occurred.

  So far, the conventional practice has been to avoid the hose group in the left and right direction, or to lift the hose that gets in the way, but it is a fundamental solution because the hose is thick and hard, and the evasion operation itself is difficult. Absent.

  On the other hand, a technique disclosed in Patent Document 1 is known as a technique related to this problem.

  In this known technique, at the time of disassembling and transporting the machine, as a means for holding a plurality of hoses on the machine body side at predetermined positions, the ends of the hoses are gripped and fixed to clamps, and the clamps are attached to the upper surface of the machine body. It is configured to be bolted to a fixed bracket.

  Therefore, this configuration is applied to a structure for holding the relay hose 9b when the unit is disassembled as shown in FIG. 12, for example, while the bracket is fixed to the adapter 8, the base end of each relay hose 9b is gripped and fixed by a clamp. However, by adopting a configuration in which the clamp is fixed to the bracket, there is a possibility that the hoses 9b can be held together without hanging.

Japanese Utility Model Publication No. 61-11327

  However, according to the above-mentioned applied technology, in order to hold and fix each hose to a clamp, a hose fixing operation (an operation of setting a hose in a hose groove of a clamp body, covering a lid, and tightening and fixing with a bolt) and conversely, The hose release operation of releasing the hose from the clamp is bothersome and time consuming.

  In addition, since the number of hoses and the position and interval in the left-right direction are determined by the clamp, there is also a problem that the degree of freedom in holding the hose is low, such as inability to cope with an increase or decrease in the number of hoses.

  SUMMARY OF THE INVENTION The present invention provides a hose holding device for a construction machine, which can simplify the work of fixing / releasing a hose and increase the degree of freedom of holding the hose.

  As a means for solving the above-mentioned problems, in the present invention, a plurality of hoses arranged in a line in the hose arrangement direction for holding the plurality of hoses so as to be fixed to a fixing portion included in the construction machine. An apparatus, wherein a plurality of brackets attached to each of the plurality of hoses, at least one suspension rod for suspending the plurality of brackets, and a bridge spanned between the suspension rod and the fixed portion. A holder for holding the plurality of hoses in a lifted state, wherein each of the plurality of brackets is detachably attached to the suspension rod and is movably locked in the rod length direction of the suspension rod. It has a locking portion.

  According to this configuration, the locking portion of each of the brackets is locked to the hanging rod, and in this state, it is only necessary to bridge the holding tool between the hanging rod and the fixed portion. The work of holding the hose can be performed easily and quickly as compared with the case of the first embodiment.

  Moreover, since each of the brackets can be easily attached to and detached from the suspension rod by the locking portion, the release / restriction of the hose for connection / separation of the hoses and the like becomes easier as compared with the clamp fixing structure.

  In addition, since each of the brackets is movable in the rod length direction of the suspension rod with respect to the suspension rod, the position and the interval in the direction in which the hoses are arranged can be freely selected and adjusted according to the number of hoses and workability. be able to. That is, the degree of freedom in holding the hose is increased.

  In this case, each of the plurality of brackets has a hanging hole as the locking portion, and the hanging rod is inserted through the hanging hole of each of the plurality of brackets so as to be freely inserted and removed in the rod length direction. Accordingly, it is desirable that the plurality of brackets be detachably attached to the suspension rod and movably locked in the rod length direction.

  With this configuration, since each bracket can be attached to and detached from the suspension rod only by inserting and removing the suspension rod from the suspension hole of each bracket, release / restriction of the hose becomes particularly easy.

  In the configuration of claim 1 or 2, the plurality of hoses include a plurality of upper hoses and a plurality of lower hoses routed with a height difference from each other, and the plurality of hoses include the upper hose and the lower hose. A holding tool is bridged, the at least one hanging rod includes an upper hanging rod that locks the plurality of upper hoses and a lower hanging rod that locks the plurality of lower hoses. It is preferable to further include a connecting tool for connecting the upper suspension rod and the lower suspension rod to each other.

  According to this configuration, when the hose groups are routed separately in two groups having a height difference, the upper and lower hose groups can be integrally held while being suspended by the upper and lower suspension rods, respectively. The work for holding the hose can be performed efficiently.

  Further, in the present invention, the apparatus further comprises a fall prevention member attached to the fixed portion to restrict the positions of the plurality of hoses from both sides in the direction in which the hoses are arranged, thereby preventing the plurality of hoses from falling down. Is desirable.

  This can prevent the lifted hose from tipping over and stabilize the hose holding state during transportation and disassembly / assembly.

  The construction machine includes a machine body having fixed piping, a work attachment detachably attached to the machine body, and a work attachment including the fixed portion, wherein the plurality of hoses are attached to the work attachment and the machine body. Each of the plurality of hoses is connected to the fixed pipe in an assembled state in which the work attachment is attached to the machine body, while the work attachment is separated from the machine body. In the case of having a main body side end separated from the fixed pipe in a state, the plurality of brackets and the at least one suspension rod are attached to the main body side end, and the holding tool is connected to the suspension rod and the work. It is good to be bridged between the fixed part of the attachment.

  According to this configuration, in the construction machine in which the machine main body and the work attachment are detached, the hose as a part of the attachment pipe (for example, a relay hose described later) at the time of disassembly / assembly prevents the main body side end from hanging down, The workability of disassembling / assembling the work attachment can be improved.

  For example, when the construction machine further includes an adapter detachably attached to the machine body, a work attachment is attached to the adapter, and the work attachment and the adapter are detached integrally, the holding tool is the suspension rod. It is good to be bridged between and the adapter.

  In this case, each of the plurality of hoses is divided into an attachment-side hose routed along the work attachment and a relay hose routed between the adapter and the fixed piping of the machine body. In the construction machine, a hose connection block is fixed to the adapter, and an end of the attachment-side hose and an end of the relay hose are connected to each other by the connection block and fixed to the adapter. It is preferable that a bracket and the at least one suspension rod are attached to the main body side end of the relay hose, and the holder is bridged between the suspension rod and the connection block.

  In this case, the hose connection block for connecting the hose on the attachment side and the relay hose can also be used as a fixing portion of the holder, so that the adaptation on the adapter side for forming the fixing portion can be minimized.

  Alternatively, the plurality of brackets and the suspension rods may be one attached to the main body side end of the relay hose, and one attached to the adapter side end of one of the relay hose and the attachment side hose. The holding tool may be bridged between the hanging rod attached to the main body side end and the hanging rod attached to the adapter side end.

  In this case, since the adapter-side end of the relay hose or the attachment-side hose serves as a fixing portion of the holder, there is no need to modify the adapter.
