  By the way, the flexible tube 17C described above for connecting the hydraulic cylinder 6 and the valve block 15 is formed in the adapter 14 so as not to hinder the expansion and contraction operation of the rod of the hydraulic cylinder 6 and the movement operation of the wires 9A and 9B. The tube holding portion 144 and the tube holding members 21 and 21 fixed in the cross member 7 on both sides of the tube holding portion 144 are held.

  For example, as shown in FIG. 7, the tube holding portion 144 includes a groove portion having a substantially C-shaped cross section formed so that the flexible tube 17 </ b> C can be fitted therein. The tube holding portion 144 has a groove entrance width smaller than the outer diameter of the flexible tube 17C so that the fitted flexible tube 17C does not easily fall off. As shown in FIG. 7, the tube holding portion 144 is preferably provided at the upper portion of the adapter 14 and opened toward the back side (left side in the drawing) from the opening portion of the cross member 7. 14 or other parts such as the top plate 71 side in the cross member 7 (upper side in the figure) and the front side in the cross member 7 (right side in the figure). It may be.

  For example, as shown in FIGS. 6 and 10, the tube holding member 21 is provided at a position sufficiently separated from the hydraulic cylinder 6 and the wires 9 </ b> A and 9 </ b> B on the top surface 71 in the cross member 7. That is, the flexible tube 17C does not interfere with the rod of the hydraulic cylinder 6 and the wires 9A and 9B as long as the flexible tube 17C is held at the three positions.

  As described above, the tube holding member 21 is desirably provided on both sides of the tube holding portion 144, but the tube holding member 21 may be provided only on one side of the tube holding portion 144. Even in this case, the flexible tube 17C may be prevented from interfering with the rod of the hydraulic cylinder 6 and the wires 9A and 9B.

  The tube holding member 21 has a structure in which the flexible tube 17C can be attached and detached from the vehicle rear side (opening side of the cross member 7). For example, the tube holding member 21 includes a ceiling plate 211 fixed along the top surface 71 of the cross member 7 and a tube support plate 212 extending substantially horizontally through a step from the ceiling plate 211 to the vehicle rear side. And an intermediate plate 213 that connects the ceiling plate 211 and the tube support plate 212 up and down. The tube holding member 21 has a portion that holds the flexible tube 17 </ b> C that opens to the vehicle rear side (opening side of the cross member 7), so that the tube support plate 212 and the top surface 71 of the cross member 7 are in contact with each other. The flexible tube 17C can be easily inserted or removed between them.

  Note that the distance between the tube support plate 212 and the top surface 71 of the cross member 7 is preferably about the same as the outer diameter of the flexible tube 17C.

  In the load receiving platform lifting apparatus configured as described above, when the electric motor 11 and the hydraulic pump 13 are driven and the solenoid valve 152 is set to the shut-off position 152a (see FIG. 11), the hydraulic oil in the hydraulic oil tank 12 is hydraulic. It is sucked into the pump 13 and supplied from the hydraulic pump 13 to the first oil passage 159a (see FIG. 11) in the valve block 15 through the flexible tube 17A. Then, the pressure oil supplied to the first oil passage 159a opens the check valve 157, and is supplied to the head side of the hydraulic cylinder 6 through the flexible tube 17C.

  As a result, the rod of the hydraulic cylinder 6 is extended, the wires 9A and 9B in the left and right posts 2 and 2 are drawn into the cross member 7, and the slider 4, the sub post 3 and the tailgate 5 are raised.

  On the other hand, when the drive of the electric motor 11 and the hydraulic pump 13 is stopped and the solenoid valve 152 is set to the communication position 152b (see FIG. 11), the head side of the hydraulic cylinder 6 and the hydraulic oil tank 12 communicate with each other. The hydraulic oil on the head side can return to the hydraulic oil tank 12. As a result, the rod of the hydraulic cylinder 6 is contracted by a load such as the tailgate 5 and a load, and the wires 9A and 9B in the cross member 7 are fed out into the left and right posts 2 and 2, and the slider 4, sub-post 3 and The tailgate 5 is lowered. Note that a flow control valve denoted by reference numeral 153 is provided to control the descending speed of the tailgate.

  Hereinafter, a procedure for mounting the hydraulic power unit 10 in the cross member 7 will be described. Prior to mounting the hydraulic power unit 10 in the cross member 7, mounting of the hydraulic cylinder 6, pulleys 81, 82, 84, wires 9 </ b> A, 9 </ b> B, etc. is completed in the cross member 7. Shall.

  First, outside the cross member 7, the base plate 16 and the sub base plate 19 are attached to the hydraulic power unit 10 in advance using bolts 147, 167, 184 and the like. Further, the hydraulic cylinder 6 and the fifth tube connecting portion 156 of the valve block 15 are connected by the flexible tube 17C, and the intermediate portion of the flexible tube 17C is fitted into the tube holding portion 144 of the adapter 14.

  Next, as shown in FIGS. 12 and 14, the hydraulic power unit 10 mounted on the base plate 19 is disposed near the opening of the cross member 7, and the flexible tube 17 </ b> C is placed on the top surface 71 in the cross member 7. The tube holding members 21 and 21 provided are respectively held (hanged). At this time, since the tube holding members 21 and 21 are easily visible from the opening of the cross member 7, the operation of holding the flexible tube 17C on the tube holding members 21 and 21 is facilitated. Further, as shown in FIG. 13, since the intermediate portion of the flexible tube 17C is held by the tube holding portion 144 formed at a relatively high position of the adapter 14, the flexible tube 17C is attached to the tube holding member 21. , 21 is more easily held (latched).

  Thereafter, the entire hydraulic power unit 10 is inserted into the cross member 7 and arranged behind the hydraulic cylinder 6.

  After the hydraulic power unit 10 is arranged in the cross member 7, the base plate 16 and the sub base plate 19 and the floor surface 73 in the cross member 7 are fixed with bolts 164, 183 and the like. Then, the upper part of the cover plate 7a is inserted into the insertion port of the main body of the cross member 7, and the lower part of the cover plate 7a is attached to the main body side of the cross member 7 with a bolt 74 or the like. Thereby, the installation of the hydraulic power unit 10 in the cross member 7 is completed.

  As shown in FIG. 3, after the installation of the hydraulic power unit 10 in the cross member 7 is completed, the flexible tube 17C is connected to the tube holding portion 144 of the adapter 14 and the tube holding members 21 and 21 provided on both sides thereof. Therefore, the flexible tube 17C is unlikely to hinder the expansion / contraction operation of the rod of the hydraulic cylinder 6 and the movement operation of the wires 9A and 9B.

  The tube holding portion 144 of the adapter 14 opens toward the back side (front of the vehicle) of the cross member 7, whereas the tube holding members 21 and 21 provided on both sides of the tube holding portion 144 are cross. Opening toward the front side (rear side of the vehicle) of the member 7, the opening directions are opposite to each other. As a result, the flexible tube 17 </ b> C is difficult to fall off from the tube holding portion 144 and the tube holding members 21 and 21. That is, when a force to move the flexible tube 17C to the front of the vehicle is applied to the flexible tube 17C due to the vibration of the vehicle, the pulsation of the hydraulic oil, etc., the movement is blocked by the tube holding members 21 and 21. 17C is unlikely to fall out of the tube holding portion 144. In addition, when a force to move the vehicle forward is applied to the flexible tube 17C, the tube holding portion 144 prevents the movement of the flexible tube 17C, so that the flexible tube 17C is unlikely to fall off the tube holding members 21 and 21. .

  In the embodiment described above, the valve block 15 is provided separately from the other components 11 to 14 of the hydraulic power unit. However, the valve block 15 is connected to the other components 11 to 14 of the hydraulic power unit. It is also possible to apply the present invention as a hydraulic power unit provided integrally.

  Further, in the embodiment described above, the tube holding portion 144 is provided in the adapter 14, but the place where the tube holding portion 144 is provided is not limited to this, and other places of the hydraulic power unit (electric motor, hydraulic oil tank) , Valve block, etc.).

  The present invention is applicable to, for example, a load receiving table lifting device provided at the rear of a load carrier of a truck.
