Description

  The present invention relates to a forklift.

  It is widely known that cargo handling is performed by a forklift. For example, when a load placed on a pallet is moved, the fork is inserted into the pallet to lift the load on the pallet. By the way, if a pallet on which a load is placed is placed at a position where the fork cannot be fully inserted into the pallet, the fork cannot lift the load. Therefore, when the fork cannot be sufficiently inserted into the pallet, for example, a sheath fork disclosed in Patent Document 1 can be used to place a load with the fork. Inserting the fork into the sheath fork increases the length of the fork and allows the fork to be fully inserted into the pallet.

  As another prior art, for example, a forklift auxiliary tool disclosed in Patent Document 2 is known. This forklift auxiliary tool includes a rectangular cylindrical body that fits into the fork, and a rectangular and cylindrical saddle member of a size that sequentially enters the main body. The main body and the saddle member constitute an expansion and contraction rod, and an attachment portion for fixing to the fork of the forklift truck is provided at the base portion of the main body which is the base portion of the expansion and contraction rod. In addition, an L-shaped engaging portion that is engaged with the pallet is detachably provided with a bolt at the tip of the telescopic rod.

  When pulling out a pallet on which a load in the back of the container is placed using this auxiliary tool for forklift, the main body is fixed to the fork of the forklift truck, and an extension rod is inserted into the insertion hole of the pallet. The fork is moved up and down, an L-shaped engagement portion is hung on the side edge or frame of the pallet, and the pallet is pulled to the container entrance. After towing, the dredged material is stored in the main body and shortened, and the pallet is transported.

  However, Patent Documents 1 and 2 have a problem in that it is necessary to attach / detach the fork or the forklift auxiliary tool to / from the fork of the forklift. The attaching / detaching operation of the heavy sheath or fork or the auxiliary tool for forklift is complicated. Moreover, a place for storing the sheath fork or the auxiliary tool for forklift is required. Furthermore, in a forklift with the sheath fork or forklift dedicated aid attached, the length of the fork is long, and the forklift or the forklift assistive device hinders the cargo handling work, such as being restricted by the small turn of the forklift. There is.

  The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a pallet placed at a position where a fork cannot be fully inserted without requiring attachment or detachment of a sheath fork or an auxiliary tool for a forklift. It is in providing a forklift that enables the handling of cargo.

  In order to solve the above-mentioned problems, the present invention provides a forklift having a mounting part capable of mounting a load and a fork provided with a rising part rising from a base end of the mounting part. Provided with a pallet locking mechanism that can be locked to the pallet, the pallet locking mechanism being rotatably provided on a side surface of the mounting portion, and having a shaft centered along the longitudinal direction of the mounting portion. A rotating shaft, and a locking portion that is provided at a tip of the rotating shaft and can be locked to the pallet in front of the tip of the mounting portion by rotating the rotating shaft. The shaft diameter is smaller than the plate thickness of the mounting portion.

  In the present invention, the load of the pallet placed at a position where the fork cannot be sufficiently inserted can be pulled out to the position where the fork is fully inserted by the pallet locking mechanism. Moreover, since the shaft diameter of the rotating shaft is smaller than the plate thickness of the mounting portion, the pallet locking mechanism provided on the fork does not hinder normal cargo handling that does not require drawing.

In the forklift described above, the locking portion may be a cylindrical shaft portion that is bent in a direction intersecting with the axis of the rotation shaft.
In this case, since the shaft portion in which a part of the rotation shaft is bent is the locking portion, the locking portion can be configured relatively easily only by bending the rotation shaft. In addition, since the shaft portion is cylindrical, a good locking state between the locking portion and the pallet can be maintained.

In the forklift described above, the rotation shaft may be provided on the inner side surface of the mounting portion.
In this case, compared with the case where the rotation shaft is provided on the outer side surface of the mounting portion, the rotation shaft is less likely to interfere with other members during handling, and damage to the pallet locking mechanism can be suppressed.

In the forklift described above, a rotation drive source that rotates the rotation shaft may be provided on the back surface of the rising portion.
In this case, since the rotation drive source of the rotation shaft is provided, the rotation shaft can be rotated by the operation of the rotation drive source.

In addition, the present invention provides a forklift having a fork having a placing part capable of placing a load and a rising part rising from a base end of the placing part, and is provided on the fork and locked to a pallet. The pallet locking mechanism is provided with a fulcrum shaft having an axial center along the width direction of the fork, and is pivotable about the fulcrum shaft. A rotating member extending in a direction, and provided at a tip of the rotating member, and protrudes and disappears from an upper surface of the mounting portion by rotation of the rotating member, and a pallet on the tip side of the mounting portion. And a thickness of the rotating member is smaller than a plate thickness of the mounting portion.
In the present invention, the load of the pallet placed at a position where the fork cannot be sufficiently inserted can be pulled out to the position where the fork is fully inserted by the pallet locking mechanism.

  ADVANTAGE OF THE INVENTION According to this invention, the forklift which enables the handling of the load of the pallet currently placed in the position which cannot fully insert a fork can be provided, without requiring attachment or detachment of a sheath fork or a forklift exclusive auxiliary tool. .

(First embodiment)
Hereinafter, the forklift according to the first embodiment will be described with reference to the drawings. Note that “front / rear”, “left / right”, and “up / down” that specify the direction are based on a state in which the forklift operator is seated on the driving seat of the driver's seat and faces the forward side of the forklift.

  As shown in FIG. 1, the forklift includes a cargo handling device 12 at the front portion of the vehicle body 11. A driver's seat 13 is provided near the center of the vehicle body 11. A driving wheel 14 as a front wheel is provided at the front portion of the vehicle body 11, and a steering wheel 15 as a rear wheel is provided at the rear portion of the vehicle body 11. A counterweight 16 is provided at the rear part of the vehicle body 11, and the counterweight 16 is for adjusting the vehicle weight and balancing the weight of the vehicle body 11. The forklift of this embodiment is an engine forklift that travels by the driving force of an internal combustion engine (not shown) mounted on the vehicle body 11. The vehicle body 11 is provided with a head guard 17 that covers the upper part of the driver's seat 13.

  The cargo handling device 12 includes a mast 20 having an outer mast 18 and an inner mast 19. The pair of left and right outer masts 18 are provided with an inner mast 19 that can slide inside the outer mast 18. Between the vehicle body 11 and the outer mast 18, a tilt cylinder 21 that is operated by hydraulic pressure is installed. The mast 20 tilts in the front-rear direction with the lower end portion as a fulcrum by the operation of the tilt cylinder 21. The mast 20 is provided with a lift cylinder 22 that is operated by hydraulic pressure. The operation of the lift cylinder 22 causes the inner mast 19 to slide up and down in the outer mast 18. The mast 20 is provided with a pair of left and right forks 30 via a lift bracket 24, and the lift bracket 24 is provided so as to move up and down with respect to the inner mast 19.

  As shown in FIG. 2, the lift bracket 24 includes a pair of upper and lower finger bars 25 and 26 and a connecting member 27 that connects both ends of the pair of upper and lower finger bars 25 and 26. The upper finger bar 25 is an upper finger bar, and the lower finger bar is a lower finger bar. The finger bars 25 and 26 are members that respectively lock the pair of left and right forks 23. A backrest 28 can be attached to the lift bracket 24 as shown in FIG. In addition, illustration of the backrest 28 is abbreviate | omitted in FIG.

  The fork 30 includes a placement portion 31 that can place a load, and a rising portion 32 that is formed by rising from the base end of the placement portion 31. The placing portion 31 and the rising portion 32 are integrally formed, and the fork 30 has a substantially L-shaped form. As shown in FIG. 3A, the placement portion 31 is formed so that the plate thickness decreases from the proximal end to the distal end. The upper surface 33 of the mounting portion 31 is a substantially horizontal flat surface, and the lower surface 34 is inclined with respect to the upper surface 33. The outer side surface 35 of the mounting portion 31 is a part of the outer surface of the fork 30, and the inner side surface 36 of the mounting portion 31 is a part of the inner surface of the fork 30. As shown in FIG. 3B, the tip of the placement portion 31 is formed in an arc shape in plan view.

  As shown in FIG. 3A, the plate thickness of the rising portion 32 is constant, and the front surface (front surface) 37 and the rear surface (back surface) 38 of the rising portion 32 are substantially vertical surfaces. The front surface 37 of the rising portion 32 and the upper surface 33 of the placement portion 31 are substantially perpendicular. An outer side surface 39 of the rising portion 32 is a part of the outer surface of the fork 23, and an inner side surface 40 of the rising portion 32 is a part of the inner surface of the fork 30. Accordingly, the side surface 35 of the mounting portion 31 and the side surface 39 of the rising portion 32 are outer surfaces of the fork 30, and the side surface 36 of the mounting portion 31 and the side surface 40 of the rising portion 32 are inner surfaces of the fork 30.

  An upper hook 41 that is locked to the finger bar 25 and a lower hook 42 that is locked to the finger bar 26 are fixed to the rear surface 38 of the rising portion 32. As shown in FIG. 3B, the upper hook 41 has a hole 44 formed in parallel with the extending direction of the rising portion 32. A lock pin 45 is inserted into the hole 44 (see FIG. 1). The lock pin 45 is a member for positioning the fork 30 with respect to the finger bar 25.

In the present embodiment, a pallet locking mechanism 50 is provided in each fork 30. The pallet locking mechanism 50 is a mechanism for pulling out a pallet of a load placed at a position where the fork 30 cannot be sufficiently inserted to a position where the fork 30 is sufficiently inserted.
The pallet locking mechanism 50 includes a rotation shaft 51 that is rotatably provided on the inner side surface 36 of the placement portion 31.

  The rotation shaft 51 includes a shaft main body 52 having an axis P along the longitudinal direction of the mounting portion 31, and a columnar shaft that is bent in a direction intersecting the axis P at the tip of the shaft main body 52. 53. The shaft body 52 is rotatably supported by a plurality (two) of shaft support members 54 attached to the inner side surface 36. The shaft main body 52 is formed with a shaft diameter enlarged portion 55 whose shaft diameter is larger than the shaft diameter of the shaft main body 52. The end surface on the distal end side of the shaft diameter enlarged portion 55 is a shaft support member 54 on the distal end side. It abuts on the end face of. The shaft diameter enlarging portion 55 is provided to receive a load in the axis P direction that the rotating shaft 51 receives when the rotating shaft 51 pulls out the pallet.

  The tip of the shaft body 52 protrudes from the tip of the mounting portion 31, and the end opposite to the tip of the shaft body 52 protrudes from the rear surface 38 of the rising portion 32 toward the lift bracket 24. As shown in FIG. 3A, since the shaft diameter of the rotation shaft 51 is smaller than the thickness of the mounting portion 31, most of the shaft main body 52 does not substantially protrude from the side surface 36 in a side view.

  The shaft portion 53 is integrally formed with the shaft main body 52 and corresponds to a locking portion that can be locked with the pallet. The shaft portion 53 normally extends inward in the width direction in front of the placement portion 31, and faces upward by the rotation of the rotation shaft 51 when pulling out the pallet. The length of the shaft portion 53 is set so as not to exceed the width of the placement portion 31 and to prevent the pallet from being pulled out. The highest portion of the shaft portion 53 in the normal state does not exceed the upper surface 33 of the placement portion 31.

  As shown in FIG. 3B, the rear surface 38 of the rising portion 32 is provided with an electric motor 56 as a rotation drive source that rotates the rotation shaft 51. The electric motor 56 and the rotation shaft 51 are connected via a gear (not shown), and the rotation of the electric motor 56 is transmitted to the rotation shaft 51. The electric motor 56 has a forward rotation for rotating the rotation shaft 51 by 90 ° so that the shaft portion 53 stands up from the normal state, and a reverse rotation of the rotation shaft 51 by 90 ° so as to return the shaft portion 53 standing up to the normal state. Reverse rotation is performed. A harness (not shown) of the electric motor 56 is connected to a connector (not shown) provided on the lift bracket 24. This connector is connected to a cable connected to a power source. The driver's seat 13 is provided with an operation switch (not shown) of the electric motor 56, and the electric motor 56 is controlled by operation of an operation switch of a forklift operator.

  Next, the cargo handling work by the forklift of this embodiment is demonstrated. As an example, the load W that is the object of the cargo handling operation is placed on a metal pallet 60 shown in FIG. The pallet 60 includes a frame member 61 that surrounds the four sides, and a flat mounting plate 62 that is fixed above and below the frame member 61. The frame member 61 is formed with an insertion port 63 into which the fork 30 can be inserted.

  When the load W of the pallet 60 is loaded at a position where the fork 30 cannot be fully inserted, for example, at the back of the truck bed, the pallet 60 is locked by the pallet locking mechanism 50 and the fork 30 can be fully inserted. Pull the pallet 60 with the load W to the position. Specific procedures for pulling out the pallet 60 are shown in FIGS. 5 (a) to 5 (c).

  First, as shown in FIG. 5A, the forklift operator inserts the fork 30 into the insertion port 63 of the pallet 60 as much as possible. At this time, the pallet locking mechanism 50 is in a normal state, and the shaft portion 53 is not standing. Next, after inserting the fork 30 as much as possible, the forklift operator rotates the electric motor 56 in the forward direction and rotates the rotating shaft 51. As shown in FIG. 5B, the shaft portion 53 stands up by the rotation of the rotation shaft 51. The operator raises the fork 30 after the shaft portion 53 stands up and retracts the forklift. The shaft portion 53 is locked to the frame member 61 of the pallet 60 by the retreat of the forklift. When the forklift is further retracted, the pallet 60 is pulled out together with the load W as shown in FIG.

  When the shaft portion 53 is locked to the mounting plate 62 of the pallet 60 and the pallet 60 is pulled out together with the load W, the rotating shaft 51 receives a load in the direction of the axis P. When the shaft diameter enlarged portion 55 is brought into contact with the shaft support member 54, the load of the rotating shaft 51 is received by the shaft support member 54.

  When the pallet 60 is pulled out together with the load W to a position where the fork 30 can be fully inserted into the pallet 60, the operator rotates the rotating shaft 51 in the reverse direction by the reverse rotation of the electric motor 56. Due to the rotation of the rotation shaft 51 in the reverse direction, the shaft portion 53 falls down and the pallet locking mechanism 50 is in a normal state. After the state of the pallet locking mechanism 50, the operator fully inserts the fork 30 into the pallet 60 and raises the fork 30 to lift the load together with the pallet 60 and move the load W. In the present embodiment, the frame member 61 of the pallet 60 is a locked portion to which the locking portion is locked. Therefore, if the fork 30 can be inserted to a position where the shaft portion 53 of the pallet locking mechanism 50 exceeds the locked portion of the pallet 60, the pallet 60 can be pulled out. When the pallet locking mechanism 50 is in a normal state, normal cargo handling work that does not require the pallet 60 to be pulled out is possible.

The forklift of this embodiment has the following effects.
(1) The load W of the pallet 60 placed at a position where the fork 30 cannot be sufficiently inserted can be pulled out to the position where the fork 30 is fully inserted by the pallet locking mechanism 50. Further, since the shaft diameter of the rotating shaft 51 is smaller than the plate thickness of the placement portion 31, the pallet locking mechanism 50 needs to be pulled out even when the pallet locking mechanism 50 is provided on the fork 30. Do not interfere with normal cargo handling.

(2) Since the locking portion is the shaft portion 53 formed by bending a part of the rotating shaft 51, the locking portion can be relatively easily obtained by simply bending the rotating shaft 51. Moreover, since the axial part 53 is cylindrical, the favorable latching state of the axial part 53 and the pallet 60 can be maintained.

(3) Since the rotation shaft 51 is provided on the inner side surface 36 of the mounting portion 31, the rotation shaft 51 rotates at the time of cargo handling as compared with the case where the rotation shaft 51 is provided on the outer side surface 35 of the mounting portion. The shaft 51 is unlikely to interfere with other members, and damage to the pallet locking mechanism 50 can be suppressed.

(4) Since the electric motor 56 as a rotation driving source for rotating the rotation shaft 51 is provided on the rear surface (back surface) 38 of the rising portion 32, the rotation shaft 51 is rotated by the operation of the electric motor 56. Can be made. Therefore, the forklift operator can operate the electric motor 56 by operating the operation switch from the driver's seat 13 when pulling out the pallet 60, and does not need to leave the driver's seat 13.

(5) When the pallet 60 is pulled out, a load in the direction of the axis P is generated on the rotating shaft 51. However, since the shaft 51 is provided with the shaft diameter enlarged portion 55 that contacts the shaft supporting member 54, the fork 30 has the shaft supporting portion. It is possible to receive a load in the direction of the axis P received by the rotating shaft 51 via the material 54.

(6) Since the pallet locking mechanism 50 is provided, it is not necessary to attach or detach the sheath fork or the forklift auxiliary tool. Moreover, a place for storing the sheath fork or the auxiliary tool for the forklift becomes unnecessary. Although the shaft portion 53 is located in front of the tip of the fork 30, the shaft portion 53 hardly interferes with the small turn of the forklift as compared with the forklift with the fork or the forklift auxiliary tool attached.

(Second Embodiment)
Next, a forklift according to a second embodiment will be described. The configuration of the pallet locking mechanism of the present embodiment is different from the configuration of the pallet locking mechanism of the first embodiment. In this embodiment, about the structure which is common in 1st Embodiment, description of 1st Embodiment is used and a common code | symbol is used.

  As shown in FIGS. 6A and 6B, a pallet locking mechanism 70 is provided in each fork 30. In FIGS. 6A and 6B, only the left fork 30 is shown, but the pallet locking mechanism 70 is also provided in the right fork 30. The pallet locking mechanism 70 is a mechanism for pulling out a pallet of a load placed at a position where the fork 30 cannot be sufficiently inserted to a position where the fork 30 is fully inserted. The pallet locking mechanism 70 includes a rotation rod 71 as a rotation member provided on the inner side surface 36 of the placement portion 31 so as to be rotatable.

  The rotary rod 71 is a long rod body 72 along the longitudinal direction of the mounting portion 31, and a shaft bent in a direction (upward) intersecting the upper surface 33 of the mounting portion 31 at the tip of the rod body 72. Part 73. The base end of the heel body 72 opposite to the shaft portion 73 is connected to a fulcrum shaft 74 provided on the rear surface 38 of the rising portion 32. The fulcrum shaft 74 is rotatably supported by a shaft support member 75 provided on the rear surface 38 of the rising portion 32 of the fork 30. The axis Q direction of the fulcrum shaft 74 is a direction along the left-right direction of the fork 30. Accordingly, the pivot rod 71 can pivot about the fulcrum shaft 74, and the pivot portion 71 is displaced in the vertical direction by the pivot rod 71, so that the pivot rod 71 protrudes and appears from the upper surface 33.

  The rear surface 38 of the rising portion 32 is provided with an electric motor 76 as a rotation drive source that rotates the fulcrum shaft 74. The fulcrum shaft 74 is connected to the electric motor 76 so that the rotation of the electric motor 76 is transmitted to the fulcrum shaft 74. On the inner side surface 36 of the fork 30, a receiving member 77 that receives the rotating rod 71 is provided. The receiving member 77 restricts the rotation of the rotating rod 71 toward the lower surface 34 side. A harness (not shown) of the electric motor 76 is connected to a connector (not shown) provided on the lift bracket 24 as in the first embodiment. The driver's seat 13 is provided with an operation switch (not shown) of the electric motor 56, and the electric motor 56 is controlled by operation of an operation switch of a forklift operator.

  The shaft portion 73 is formed integrally with the bag main body 72 and corresponds to a locking portion that enables locking with the pallet when the pallet is pulled out. Although the shaft portion 73 stands up, the tip end of the shaft portion 73 does not exceed the upper surface 33 of the placement portion 31 in a normal state where the rotation rod 71 is not rotated. When the pivot rod 71 is pivoted in one direction (counterclockwise direction in FIG. 6A), the shaft portion 73 is displaced beyond the upper surface 33. When the shaft 73 is displaced beyond the upper surface 33, when the pivot rod 71 is pivoted in the other direction (clockwise direction in FIG. 6A), the rod body 72 is moved to the receiving member 77. The shaft portion 73 is returned to the original position after being received.

  When the forklift operator pulls out the pallet 60, after the tip of the fork 30 is aligned with the gap G, the electric motor 76 is operated to rotate the rotating rod 71 around the fulcrum shaft 74. The shaft 73 is displaced beyond the upper surface 33 by the rotation of the rotating rod 71 and can be locked to the pallet 60. According to this embodiment, there exists an effect equivalent to the effect (1)-(4), (6) of 1st Embodiment.

  The present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the gist of the invention. For example, the following modifications may be made.

In the above embodiment, the rotation drive source that rotates the rotation shaft or the rotation rod is provided, but the rotation drive source is not an essential requirement. For example, the rotating shaft or the rotating rod may be rotated by an operator's human power. When the rotating shaft or the rotating rod is rotated by the operator's human power, it is preferable to provide a mechanical mechanism that enables the rotating shaft or the rotating rod to rotate at the driver's seat. It is not hindered to leave the seat and directly operate the pivot shaft or pivot.
In the above embodiment, the electric motor is used as the rotation drive source of the rotation shaft or the rotation rod, but the rotation drive source is not limited to the electric motor. For example, a hydraulic cylinder may be used as the rotation drive source.
In the above embodiment, the locking portion is a shaft portion formed by bending a part of the rotating shaft or the rotating rod, but this is not restrictive. The locking portion may be a separate member that constitutes a part of the rotating shaft or the rotating rod. Moreover, a latching | locking part is not limited to a shaft part, If the latching with a pallet is possible, the shape is free.
In the above embodiment, the rotating shaft or the rotating rod is provided on the inner side surface of the fork. However, the rotating shaft or the rotating rod may be provided on the outer side surface of the fork. Alternatively, for example, a rotating shaft or a rotating rod may be provided on the inner side surface of the right fork, and a rotating shaft or a rotating rod may be provided on the outer side surface of the left fork.
In the above embodiment, a metal pallet is used, but a wooden pallet 80 shown in FIG. The wood pallet 80 includes three girder members 81 arranged in parallel to each other and a plurality of deck boards 82 fixed to the top and bottom of the girder member 81. An insertion port 83 into which the fork 30 can be inserted is formed between the beam members 81. The deck board 82 is disposed in a direction intersecting the longitudinal direction of the beam member 81, and a gap G is formed between the deck boards 82 adjacent to each other. When pulling out the wooden pallet 80, a locking portion may be inserted into the gap G to lock the wooden pallet 80. If the gap G side of the deck board 82 of the wooden pallet 80 is the locked portion, and the fork 30 can be inserted to a position where the locking portion of the pallet locking mechanism exceeds the locked portion of the wooden pallet 80, The pallet 80 can be pulled out.
