When the ascending pedal 23 is stepped on, hydraulic oil is supplied to the hydraulic cylinder 21 in the direction in which the telescopic rod 21a of the hydraulic cylinder 21 is extended. When the lowering pedal 24 is stepped on, hydraulic oil is supplied to the hydraulic cylinder 21 in a direction in which the telescopic rod 21a of the hydraulic cylinder 21 is drawn.

  When the telescopic rod 21a extends, the support legs 11 and 12 extend upward, and the table 2 rises while maintaining a horizontal posture. Conversely, when the telescopic rod 21a is retracted, the support legs 11 and 12 are contracted downward, and the table 2 is lowered. In this example, the table 2 can be moved up and down between a maximum height position 2H indicated by a solid line in FIG. 2 and a minimum height position 2L indicated by a two-dot chain line.

  At the four corners of the gantry 14, height adjustable outriggers 17 are attached. By extending each of the outriggers 17 downward, the gantry 14 can be placed horizontally in a stable state on the floor surface or the like. That is, the table 2 can be in a stable horizontal posture.

  FIG. 4 is an explanatory view showing a housing structure for the right free rollers 5a and 5b. The structure of each part will be described in more detail with reference to FIG.

  First, the storage structure of the right free rollers 5a and 5b will be described. As can be seen from FIGS. 3A and 3C, the right free roller 5a is supported by the roller bracket 31 in a rotatable state. The roller bracket 31 includes a rectangular bottom plate portion 31a and end plate portions 31b and 31c standing upright from both ends of the bottom plate portion 31a. The right free roller 5a is spanned between the end plate portions 31b and 31c in a rotatable state.

  As can be seen from FIG. 3A and FIG. 4, the roller bracket 31 is attached to the edge of the roller storage opening 7 a in the table 2 in a rotatable state by a pair of hinges 32. A state where the bottom plate portion 31 a of the roller bracket 31 is positioned on the table surface 3 of the table 2 is a roller use position. When the roller bracket 31 is turned 180 degrees around the hinge 32 from this roller use position, the right free roller 5a reaches the roller storage position below the table surface 3 from the roller storage opening 7a.

  The bottom plate portion 31a of the roller bracket 31 is just sized to fit into the roller storage opening 7a, and the roller storage opening 7a is sealed at the roller storage position. At the opening edge of the roller storing opening 7 a, the edge of a pair of rectangular plates 33 attached to the back surface of the plate defining the table surface 3 protrudes, and the edge of the bottom plate portion 31 a is the edge of the plate 33. Engage with the edge. Thereby, the roller bracket 31 is held in the roller storage position in a state where the roller storage opening 7a is sealed.

  Moreover, as can be seen from FIG. 3A, a semicircular recess 31 d for attaching a finger is provided on the opening / closing side edge of the bottom plate portion 31 a of the roller bracket 31. Thereby, turning of the roller bracket 31 can be performed easily. That is, the operation of turning the right free roller 5a to the roller use position and the roller storage position can be easily performed.

  In addition, the storage structure of the other right free roller 5b and the left free rollers 4a and 4b is also configured similarly to the right free roller 5a. Therefore, description of these storage structures is omitted.

  Next, the turning structure of the table 2 will be described. As shown in FIGS. 3A to 3C, a turning support shaft 35 that defines a turning center line 2 a is attached to the center of the back surface of the table 2. The pivot support shaft 35 projects vertically downward. A bearing portion 36 that supports the swivel support shaft 35 in a rotatable state is attached to the upper surface of the table support board 8. Further, four casters 37 are vertically attached to the upper surface of the table support board 8 so as to be positioned on the same circle centering on the turning center line 2a. The rotation axis of each caster 37 is horizontally arranged facing the turning center 2a. The table 2 is supported while being placed on these four casters 37. The caster 37 at a fixed position rolls, and the table 2 can be smoothly turned around the turning center line 2a.

Here, as can be seen from FIG. 4, when the turning lock lever 9 a is operated in the turning lock mechanism 9 of the table 2, the locking shaft 9 b is pushed out and pressed against the outer peripheral side surface 2 b of the table 2. When the locking shaft 9b is pushed out, the turning of the table 2 is locked.
(Function and effect)
A case where work is performed on a workpiece using the work table 1 configured as described above will be described. First, when the workpiece 100 is placed on the table 2 of the work table 1, the lowering pedal 24 is depressed to lower the table 2 to the lowest height position 2L. Thereby, the heavy workpiece | work 100, for example, a wheelchair, can be easily mounted on the table 2. FIG.

  When the maintenance work of each part is performed at the fixed height position of the workpiece 100, the lifting pedal 23 is stepped on to raise the table 2 so that the workpiece 100 is set to the optimum height position for the worker. . Maintenance work can be performed by positioning the workpiece 100 at a height corresponding to the difference in extension between men, women, and the elderly, so it is impossible to cause back pain such as bending the waist. There is no need to do the work. Therefore, it is possible to perform work in a state where there is no burden on the waist.

  Similarly, in the hand-washing operation of the workpiece 100 using a brush, it is not necessary to perform the operation while the worker is squatting on the workpiece placed on the floor, and the hand-washing operation is performed in a standing posture that does not burden the waist. be able to.

  Further, in the high-pressure cleaning of the workpiece 100, it is not necessary to perform the cleaning operation while the worker moves around the workpiece placed on the floor or the like, and the table 2 on which the workpiece 100 is placed turns so that the fixed position is obtained. High pressure cleaning can be performed in Therefore, it is not necessary to draw the hose around the workpiece 100, and the cleaning operation can be easily performed.

  Furthermore, the table 2 can be locked at an arbitrary turning position. Therefore, it is not necessary to perform an operation on the workpiece 100 in an unstable state placed on the turnable table 2 in operations such as inspection of a fixed part of the workpiece 100 and parts replacement.

  Furthermore, when performing a clearing operation with force on the workpiece 100 on the table 2, it is necessary to make the workpiece 100 stable so that it does not move or shake. In this case, not only the turning of the table 2 is locked, but also the outriggers 17 at the four corners of the gantry 14 are projected downward, so that the work table 1 can be fixed securely. Therefore, the work can be performed on the work in a stable state as in the work with the work 100 placed on the floor.

  Next, in the work of removing dirt on the tires of the wheels 101L and 101R of the workpiece 100, the wheels 101L and 101R are placed on the left and right free rollers 4a, 4b, 5a, and 5b, and are in a rotatable state. Yes. Therefore, since each wheel 101L and 101R can be easily rotated, work becomes easy. Similarly, in the lap winding operation of the tire after the completion of the operation, the operation can be performed very easily because the wrapping can be performed while rotating the tire. In addition, it is convenient because operations such as distortion check of each part of the tire can be easily performed while turning the tire.

  Next, in the work of checking the brake of the workpiece 100, it is necessary to apply the brake while pressing the workpiece 100 on the table 2 to check the effectiveness. In such work, the left and right free rollers 4a, 4b, 5a, and 5b may get in the way. In this case, when the left and right free rollers 4a, 4b, 5a, and 5b are stored below the table surface 3, the table surface 3 becomes a flat surface as a whole. Therefore, such work can also be performed on the table 2 in the same manner as when performed on a conventional floor surface.

  In addition, the table 2 can be raised and lowered by stepping on the raising pedal 23 and the lowering pedal 24. Therefore, the table 2 can be moved up and down by stepping while performing manual work, and the workpiece 100 placed thereon can be positioned at an appropriate height position. Therefore, it is possible to efficiently perform inspection work, parts replacement work, cleaning work and the like of parts having different heights in the work.
