Description

  The present invention relates to an industrial vehicle provided with a fork in which electronic components are disposed at the tip of the fork.

In recent years, forklifts as industrial vehicles are sometimes equipped with electronic parts such as a camera at the tip of a fork for the purpose of assisting a pilot and enhancing the functionality of an unmanned forklift.
The electronic component includes a wire harness, and the electronic component and a controller of the electronic component attached to the machine base are connected via a connector by a wire harness extending from both.

  In addition, although the forklift performs loading work by inserting a fork into a load, damage may occur if the wire harness contacts the load. Therefore, as in Patent Document 1, the wire harness disposed along the fork is covered by a cover.

  As shown in FIGS. 10A and 10B, in Patent Document 1, a CCD camera 91 as an electronic component is built in the tip of the fork 93, and a cable 92 from the CCD camera 91 is It is passed through an iron square pipe 94 provided on the side surface of the fork 93.

JP 2005-104652 A

  However, in Patent Document 1, since it is necessary to pass the cable 92 through the square pipe 94, the wiring operation is difficult. When a connector is attached to the end of the cable 92, the connector is also passed through the square pipe 94.

  When the connector is disposed in the square pipe 94, it is difficult to attach and detach the connector. Therefore, in consideration of the removability of the connector, when the connector is disposed on the side of the bent portion where the fork 93 is bent, the cable 92 extending from the electronic component is made longer than the length of the square pipe 94. However, the length of the fork 4 may differ depending on the specifications of the machine base, and accordingly the length of the square pipe 94 will also differ depending on the length of the fork 93. Therefore, in order to make the length of the cable 92 longer than the length of the square pipe 94, the length of the cable 92 also has to be changed according to the length (type) of the fork 93, so the type of electronic parts increases and the cost increases. Will increase.

  The present invention has been made in view of the above problems, and an object thereof is to provide an industrial vehicle capable of easily performing wiring work without changing the length of a wire harness extending from an electronic component. It is.

  The industrial vehicle which solves the said subject is an industrial vehicle which has a fork, the electronic component arrange | positioned at the front-end | tip of the said fork, and the wire harness which extends from the said electronic component and has a connector at the front-end of a cable. The fork includes a fork main body for supporting a load, the connector and the cable are disposed on a narrow surface of the surface along the extending direction of the fork main body, and the fork has the narrow surface. A cover attached to the cable and the connector, the cover being removable from the fork main body.

  According to this configuration, the cable and the connector disposed on the narrow surface of the fork body can be protected by the cover attached to the fork body so as to cover them. This suppresses damage to the wire harness. In addition, since the cable can be disposed on the fork main body in a state where the cover is removed from the fork main body, the arrangement of the cable and the connector becomes easier as compared with the case where the cable is passed through the square pipe It becomes easy.

  In addition, the fork includes at least two protrusions projecting from the narrow surface and arranged in parallel in the extending direction of the fork, and a beam member provided in the protrusions. Are disposed along the beam member.

  According to this configuration, the cable can be easily disposed in the narrow surface of the fork main body by hooking the cable on the protrusion and along the beam member, and the connector integrated with the cable can also be disposed in the narrow surface. It's easy to do. Thus, the cable can be easily attached to and removed from the fork main body.

Further, the cable is hooked to the beam member by a hook.
According to this configuration, the fastener can maintain the state in which the cable is disposed along the beam member.

Further, the cable is supported on the upper surface of the beam member.
According to this configuration, the cable can be prevented from hanging down below the beam member, and the state in which the cable is disposed along the beam member can be maintained.

  Further, the cover includes an insertion hole through which the protrusion is inserted, and an abutment portion around the insertion hole, and the insertion portion is inserted into the projection and one end thereof is in contact with the narrow surface of the fork main body. The other end is in contact with the spacer which abuts against the cover, a mounting member attached to the projection which penetrates the insertion hole and which protrudes to the outside of the cover, and is mounted to the projection outside the cover. It has an elastic member pinched between the contact part and the attachment member.

  According to this configuration, since the cover has a structure that allows deformation of the fork main body, damage to the cover can be suppressed even when the fork main body is bent. Further, the position of the mounting member is regulated by the spacer, and the deformation of the elastic member can maintain the cover attached to the fork main body with an appropriate axial force. In addition, when the cover is subjected to an external force, the deformation of the cover can be permitted by the deformation of the elastic member, and damage to the cover can be suppressed.

  According to the present invention, the wiring operation can be easily performed without changing the length of the wire harness extending from the electronic component.

The present invention will be described on the basis of application to an unmanned forklift equipped with a driver's seat 3.

  As shown in FIG. 2, the fork 4 is attached to the fork main body 11 for supporting a load and the fork main body side surface 31 forming the side of the fork main body 11, and a cover which constitutes the fork 4 integrally with the fork main body 11. And 12. The length in the extension direction of the fork 4 differs depending on the specifications of the machine base. A direction along the upper surface 17 of the fork 4 and orthogonal to the extending direction of the fork 4 is taken as a width direction.

  In addition, the tip of the fork 4 is provided with a sensing unit 6. The sensing unit 6 includes an electronic component 15 and an upper piece 13 and a lower piece 14 covering the upper and lower portions thereof. The electronic component 15 is used for work support when the operator carries out cargo handling and for the unmanned operation of the forklift 1, and examples of the product include a CCD camera and a distance measuring sensor.

  As shown in FIG. 3, the upper piece 13 is attached to the tip of the fork main body 11. The upper surface of the upper piece 13 is integrated by welding so as to be flush with the upper surface 17 of the fork main body 11 so that the loading surface 16 of the fork 4 is flat. Further, the upper piece 13 is provided with a plurality of upper attachment pieces 18 extending downward from edges located at both ends in the width direction of the fork 4, and the plurality of upper attachment pieces 18 are provided with attachment holes 19.

  The electronic component 15 is mounted on the lower piece 14. A plurality of lower mounting pieces 20 are provided on both sides of the lower piece 14 in the width direction of the electronic component 15, and the plurality of lower mounting pieces 20 are provided with mounting holes 19 having female threads. The lower piece 14 is fixed to the upper piece 13 by the bolts 21 passing through the attachment holes 19 of the upper piece 13 and being screwed into the attachment holes 19 of the lower piece 14. By this method, the lower piece 14 and the electronic component 15 are attached to the upper piece 13 and to the fork main body 11. Further, the lower surface 25 of the lower piece 14 is flush with the lower surface 27 of the fork main body 11 so that the non-loading surface 26 of the fork 4 is flat. Thus, the electronic component 15 is disposed at the tip of the fork main body 11, and the tip of the fork 4 is constituted by the upper piece 13 and the lower piece 14.

  As shown in FIG. 3 and FIG. 7, the electronic component 15 is provided with a cable 22 for supplying power and performing information communication, and a connector 24 a as a connection component is attached to the tip of each cable 22. Further, the plurality of cables 22 (three cables in the present embodiment) extending from the electronic component 15 and the connectors 24a are combined with a tape or the like to constitute a wire harness 23a. The wire harness 23a extending from the electronic component 15 and the wire harness 23b extending from a controller (not shown) mounted on the vehicle body 2 are connected by connectors 24a and 24b provided on the wire harnesses 23a and 23b.

  As shown in FIG. 5 and FIG. 6, the fork 4 is provided with a plurality of stud bolts 32 as protrusions on the fork main body side surface 31 (two in the present embodiment). As shown in FIG. 5, the stud bolt 32 is fixed to the fork main body 11 so as to protrude from the side surface 31 of the fork main body in a state where the male screw 32 a at one end is screwed with the female screw 11 a of the fork main body 11. Further, as shown in FIG. 6, the plurality of stud bolts 32 are disposed on a straight line L located parallel to the extending direction of the fork main body 11 and between the upper surface 17 and the lower surface 27 in the fork main body side surface 31. . Further, as shown in FIGS. 5 and 6, the male screw 32 b at the other end of the stud bolt 32 protrudes from the fork main body side surface 31.

  The spacer 33 is attached to the stud bolt 32. The spacer 33 is made of metal and has a cylindrical shape. Beam members 34 are integrally formed on the spacers 33 attached to the pair of stud bolts 32 so as to bridge a bridge between the adjacent stud bolts 32. The beam member 34 has a cylindrical shape made of metal.

  The cover 12 attached to the fork main body side surface 31 is made of metal. As shown in FIG. 8, the dimension in the longitudinal direction of the cover 12 is substantially the same as the dimension between the bent portion 35 where the fork main body 11 is bent and the tip of the fork main body 11. The cross-sectional shape of the cover 12 in the width direction of the fork 4 is U-shaped. The cover 12 has a side wall 36 disposed opposite to the fork main body side surface 31, an upper side wall 37 projecting from the edge of the upper end of the side wall 36, and a lower side wall 38 projecting from the edge of the lower end of the side wall 36. The sum of the length in the width direction of the fork 4 in the upper side wall 37 and the lower side wall 38 and the length in the width direction of the fork 4 in the fork main body 11 is equal to the length in the width direction of the fork 4 in the upper piece 13. With this configuration, when the cover 12 is attached to the fork main body 11, the side surface of the fork 4 becomes flush, and the side surface of the fork 4 is less likely to be caught by the load when inserting the fork 4 under the load to be handled.

  Further, the length in the width direction of the fork 4 in the fork main body 11 is more in the width direction of the fork 4 in the upper side wall 37 and the lower side wall 38 than the length in the width direction of the fork 4 in the upper piece 13 and the lower piece 14. Short by the length of Thus, a gap is formed between the upper mounting piece 18 of the upper piece 13 and the side surface 31 of the fork main body.

  Next, the attachment structure of the cover 12 will be described. As shown in FIG. 5 or FIG. 8, the cover 12 is provided with a recess 41 on both sides in the longitudinal direction of the side wall 36, and a contact portion 42 at the bottom of the recess 41. In addition, the cover 12 includes an insertion hole 43 surrounded by the contact portion 42. The stud bolt 32 and the spacer 33 are inserted into the insertion hole 43 of the cover 12. The stud bolt 32 protruding from the fork main body side surface 31 is located in the recess 41 and has a length that does not protrude from the outer surface of the side wall 36.

  An elastic member 44 is mounted on the outer peripheral side of the spacer 33 protruding from the contact portion 42 of the cover 12. The elastic member 44 is made of urethane and has an annular shape. The elastic member 44 is supported by the portion of the contact portion 42 which is the inner bottom surface of the recess 41. Further, the washer 45 is attached to the male screw 32 b of the stud bolt 32 projecting from the fork main body side surface 31, and the washer 45 contacts the spacer 33. A nut 46 as a mounting member is screwed into the male screw 32 b of the stud bolt 32 via a washer 45. The cover 12 is attached to the fork main body 11 by screwing the nut 46.

  As shown in FIG. 5, the tip end surface of the cover 12 facing the fork main body side surface 31 of the upper side wall 37 and the tip end surface of the lower side wall 38 facing the fork main body side surface 31 contact the fork main body side surface 31. After the elastic member 44 and the washer 45 are inserted into the stud bolt 32 projecting from the fork main body side surface 31, the nut 46 is screwed into the male screw 32b, whereby the elastic member 44 and the contact portion 42 It is held between the washers 45 and in a compressed state.

  One end of the spacer 33 in the axial direction abuts on the side surface 31 of the fork main body, and the other end in the axial direction of the spacer 33 abuts on the nut 46 via the washer 45. By the spacer 33, the screwing position of the nut 46 is determined at a position separated by a predetermined distance from the fork main body side surface 31, and the further screwing is restricted. In a state in which the screwing of the nut 46 is restricted, the elastic member 44 deforms into a compressed state, and provides an axial force for attaching the cover 12 to the fork main body 11.

  As shown in FIGS. 4 and 7, on the fork main body side surface 31, the electronic components 15 and wire harnesses 23a and 23b extending from the controller are disposed. The wire harnesses 23 a and 23 b are disposed along the fork main body side surface 31. In addition, the wire harnesses 23a and 23b are attached to the beam member 34 using the annular hook-shaped fastener 47. The hooking tool 47 is a binding band or a cord, and one that can be easily shaped into an annular shape is used. The cover 12 is attached to the fork main body 11 in a state in which the wire harnesses 23a and 23b are latched to the beam member 34, and the wire harnesses 23a and 23b are covered by the cover 12.

Next, the wiring operation of the wire harness and the coupling (detachment) operation of the connector in the configuration of the present embodiment will be described.
First, the lower piece 14 on which the electronic component 15 is mounted is attached to the upper piece 13 provided at the tip of the fork main body 11 by the bolt 21. At this time, the wire harness 23 a extending from the electronic component 15 is passed through the gap formed between the upper mounting piece 18 and the fork main body side surface 31. Further, the spacer 33 integrated with the beam member 34 is inserted into the stud bolt 32.

  Next, the wire harness 23 a is disposed along the beam member 34, and the wire harness 23 a and the beam member 34 are bundled and attached by the hooking tool 47. Similarly, the wire harness 23 b extending from the controller is disposed along the beam member 34, and the wire harness 23 b and the beam member 34 are bundled and attached by the hook 47. Then, the connector 24a of the wire harness 23a extending from the electronic component is coupled to the connector 24b of the wire harness 23b extending from the controller.

  After the connectors 24 a and 24 b are connected, the insertion holes 43 of the spacer 33 and the cover 12 are inserted into the stud bolts 32. Finally, the elastic member 44 and the washer 45 are inserted into the stud bolt 32, and the nut 46 is screwed into the stud bolt 32 so as to press the elastic member 44 in the axial direction of the stud bolt 32.

  By the way, when carrying out cargo handling work using fork 4 of forklift 1, there are cases where cargo handling work is performed using only the tip of fork 4. In this case, a load is concentrated on the tip of the fork 4 and a force is exerted on the fork 4 in the extension direction of the fork 4 and the fork main body 11 is bent. The cover 12 is attached to a stud bolt 32 of the fork main body 11. Therefore, like the fork main body 11, the load on the tip of the fork 4 causes the cover 12 to be bent in the extending direction of the cover 12. Since the stud bolt 32 is disposed on the straight line L parallel to the extending direction of the fork main body 11 and positioned between the upper surface 17 and the lower surface 27 on the fork main body side surface 31, the stud by the force of bending the fork main body 11 Between the bolt 32 and the cover 12, a moment of force acts around the central axis of the stud bolt 32. On the other hand, in the cover 12, the nut 46 is screwed in via the washer 45 in a state in which the elastic member 44 is in contact with the contact portion 42, so the fork main body is in a state in which the elastic member 44 is deformable. It is attached to 11.

  Therefore, the elastic member 44 receives a moment of force and shears around the central axis of the stud bolt 32. Therefore, the cover 12 can allow bending deformation of the fork main body 11 while maintaining axial force necessary for attaching to the fork main body 11 by shear deformation of the elastic member 44.

According to this embodiment, the following effects can be obtained.
(1) The wire harness 23 a (the cable 22 and the connector 24 a) extending from the electronic component 15 provided at the tip of the fork 4 is disposed on the fork main body side surface 31 of the fork main body 11. Further, the cable 22 and the connector 24 a disposed on the fork main body side surface 31 are covered by the cover 12. A wire harness 23 b extending from a controller (not shown) mounted on the vehicle body 2 is also disposed on the fork main body side surface 31 of the fork main body 11.

  With this configuration, it is possible to perform the wiring operation and the mounting and dismounting operation with the cover 12 protecting the wire harnesses 23a and 23b removed. Therefore, for example, wiring work of the wire harnesses 23a and 23b can be easily performed and attachment and detachment work of the connectors 24a and 24b can be easily performed as compared with the case where the wire harnesses 23a and 23b are passed through square pipes. Can.

  In addition, since it is not necessary to prevent the connectors 24a and 24b from being disposed in the square pipe in consideration of the detachable property, the length of the wire harness 23a is constant even if the length in the extension direction of the fork 4 is different. It is possible to design and eliminate the need to manufacture multiple types of electronic components 15.

  Furthermore, in consideration of the connector removability and the reduction in the number of parts, the method for storing the connectors 24a and 24b at the tip of the fork 4 does not have to provide a space for storing the connectors 24a and 24b at the tip of the fork 4 Since it is only necessary to provide a space for the electronic component 15 at the tip of the fork 4, it is difficult to reduce the bending rigidity at the tip of the fork 4.

(2) The wire harnesses 23 a and 23 b disposed on the fork main body side surface 31 are disposed along the beam members 34 extending along the fork main body side surface 31.
With this configuration, the wire harnesses 23a and 23b are disposed along the beam member 34, so that the cover 12 can be easily positioned between the upper side wall 37 and the lower side wall 38 when the cover 12 is attached. .

  In addition, since it is not necessary to newly provide the fork main body 11 with a groove or the like for arranging the wire harnesses 23a and 23b in the fork main body 11, the wire harnesses 23a and 23b can be It can be arranged on the fork body 11.

(3) The wire harnesses 23 a and 23 b are attached to the beam member 34 by the fastener 47.
With this configuration, the wire harnesses 23a and 23b can be maintained along the beam member 34, and when the cover 12 is attached to the fork main body 11, the wire harnesses 23a and 23b can be disposed along the beam member 34. Thus, the cover 12 can be attached without the wire harnesses 23a and 23b being in the way.

Further, since the wire harnesses 23a and 23b are firmly fixed to the beam member 34, the attached state of the wire harnesses 23a and 23b is maintained even when used for a long time.
(4) The elastic member 44 is held between the contact portion 42 of the cover 12 and the nut 46.

  With this configuration, even if the fork main body 11 is bent, the elastic deformation of the cover 12 is alleviated by the elastic deformation of the elastic member 44 around the axis of the stud bolt 32. Therefore, as compared with the case where the cover 12 is firmly fixed to the fork main body 11, the cover 12 is less likely to be damaged.

(5) The stud bolt 32 protruding from the fork main body side surface 31 is formed by screwing the stud bolt 32 into the female screw 11 a of the fork main body side surface 31.
With this configuration, attachment of the cover 12 to the fork main body 11 can be combined with support of the beam member 34 for attaching the wire harnesses 23a and 23b by one member of the stud bolt 32.

  (6) The cover 12 is provided with the recess 41 on both sides in the longitudinal direction of the side wall 36, and the contact portion 42 at the bottom of the recess 41. Further, in the cover 12, an insertion hole 43 for inserting the stud bolt 32 is provided at a position surrounded by the contact portion 42, and the cover 12 is screwed with the nut 46 on the male screw 32 b of the stud bolt 32. It is fixed.

  With this configuration, the cover 12 can be fixed in a state in which the nut 46 is housed in the space formed by the recess 41 of the cover 12. Therefore, even if the stud bolt 32 is inserted into the insertion hole 43 of the cover 12 and the nut 46 is screwed into the male screw 32 b of the stud bolt 32, the nut 46 and the stud bolt 32 can be attached so as not to protrude from the cover 12.

  (7) The cover 12 is attached to the fork main body 11 in a state where the front end surface of the upper side wall 37 and the front end surface of the lower side wall 38 are in contact with the fork main body side surface 31. Further, in the attached state of the cover 12, the elastic member 44 is sandwiched between the contact portion 42 and the washer 45 and is in a compressed state.

The compressed elastic member 44 provides an appropriate axial force for attaching the cover 12 to the fork main body 11 and allows bending deformation of the fork main body 11.

The industrial vehicle which equips the said projection part with the outer side of the said cover, and has an elastic member clamped between the said contact part and the said attachment member.

  According to this, for example, as in Patent Document 1, the cover may be welded to the fork main body as a square pipe. In this case, since the cover deforms following the deformation of the fork main body, the cover may be damaged when the fork main body is bent. However, by adopting the above-described cover attachment structure, the cover has a structure that allows for deformation of the fork main body, so that even if the fork main body is bent, damage to the cover can be suppressed. Further, the position of the mounting member is regulated by the spacer, and the cover can maintain the state in which the deformation of the elastic member, which is deformed with respect to the fork main body, is attached with an appropriate axial force. In addition, when the cover receives an external force, damage to the cover can be suppressed.
