Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mobile basket stand whose position can be fixed with outriggers.

[Prior Art] As shown in FIG. 10, a mobile basket stand includes a basket 1, a backboard 2 that supports the basket 1, a board support arm 3 that supports the backboard 2, and the board support arm 3. A traveling trolley 4 that is supported so as to be able to rise and fall (raise and lower), an arm lifting device 5 such as a hydraulic cylinder that is supported by the traveling trolley 4 or the board support arm 3 and that raises and lowers the board supporting arm 3, and the traveling trolley. Those equipped with outriggers 6 for fixing the position of 4 are widely used.

[Problems to be Solved by the Invention] Conventional mobile basket stands of this type generally have a problem in that the outriggers have a complicated structure and are troublesome to operate.

The present invention is a means for providing a mobile basket stand equipped with outriggers that has a relatively simple structure and does not require troublesome operations.

[Means for solving the problem] An outrigger is equipped with a ground base, a bolt rod planted on the ground base, a nut screwed onto the bolt rod, and the nut is attached to the ground base. A bolt receiver collar that supports the ground base on a traveling truck so as to be able to move upwardly and downwardly through a nut and a bolt lever; and a bolt lever rotation operating body that is rotatably attached to the bolt receiver collar via a bearing. and a connecting shaft provided at the upper end of the bolt rod can be slid in the axial direction on a bearing portion provided on the lower surface of the bolt rod rotation operating body,
In addition, it is constructed by being fitted to the bolt rod rotation operating body so that relative rotation is impossible.

[Function] When the bolt rod rotation operating body is turned in one direction, the bolt rod rotates through the bearing and the connecting shaft, and the bolt rod rotates inside the nut and descends. The installation base touches the floor and fixes the position of the traveling trolley.

If the bolt rod rotation operating body is turned in the other direction, the bolt rod will rise, lifting the ground base from the floor and making the traveling vehicle ready for travel.

[Example] Next, an example of the present invention will be described with reference to FIGS. 1 to 9. 1 is the basket, 2 is the backboard to which basket 1 is attached, 3 is the backboard 2
A board support arm 4 supports the board support arm 3, a traveling trolley supporting the board support arm 3 in a manner that allows it to rise and fall (up and down), and a reference numeral 5 attached to the traveling trolley 4;
This is an arm lifting device that lifts and lowers the board support arm 3.

The backboard 2 has an aluminum frame 2b attached to the four peripheries of an acrylic plate 2a using fasteners 2c such as bolts and nuts.
It is formed by tightening with.

Further, the board support arm 3 has one end pivotally supported by the traveling cart 4, and the arm lifting device 5.
a first arm 3a that is raised and lowered by a second arm 3a; Arm 3b
One end of the second arm 3b is pivoted to the pivot side end of the first arm 3a, and the other end is connected to the traveling carriage 4.
a third arm which is pivotally supported by the first arm 3a, moves up and down together with the first arm 3a, and extends the second arm 3b at a substantially right angle when the first arm 3a is raised or erected;
It is composed of an arm 3c. 3d is a pivot shaft that pivotally supports the second arm 3b at the tip of the first arm 3a, 3e is a bearing protrusion provided on the upper part of the first arm 3a, and 3f is the lower surface of one end of the second arm 3b. 3g is a roller attached to one side of the recess 3f, and 3h is a V-shaped roller holder provided on one side of the first arm 3a.
The second arm 3b is rotatably (foldably) supported at the tip of the first arm 3a by a pivot shaft 3d with the bearing protrusion 3e fitted into the recess 3f. When the second arm 3b is extended at a substantially right angle to the arm 3a, the roller 3g
is fitted into the roller holder 3h and the second arm 3
b and the backboard 2 attached to its tip are prevented from rolling.

Further, the traveling trolley 4 is made to be able to travel by front wheels 4a and rear wheels 4b, and a hydraulic cylinder is used for the arm lifting device 5, so that the traveling trolley 4 can be moved.
A cylinder body 5a is attached to the side, and the first arm 3a and third arm 3c are raised and lowered by extending and contracting the piston rod 5b.

The outrigger 6 according to the present invention includes a grounding base 7, a bolt rod 8 planted on the grounding base 7, and a nut 9 screwed onto the bolt rod 8.
, a bolt receiver collar 10 to which the nuts 9 are attached and which supports the grounding base 7 on the traveling carriage 4 so as to be movable up and down via the nuts 9 and bolt rods 8; and the bolt receiver collar 10. A bolt rod rotation operation body 12 is rotatably attached to the bolt rod rotation operation body 12 via a bearing 11, and a bearing portion 13 provided on the lower surface of the bolt rod rotation operation body 12 is provided at the upper end of the bolt rod 8. The connecting shaft 14 is configured to be slidable in the axial direction and fitted to the bolt rod rotation operating body 12 so as not to be relatively rotatable.

The grounding base 7 is made of a non-slip rubber plate 7a.
It consists of a metal base main body 7b with the plate rubber 7a adhered to the lower surface, and a bolt rod receiving cylindrical part 7d rotatably mounted on the base main body 7b via a slide bearing 7c. There is.

In addition, a hexagonal bar-shaped connecting shaft 1 is attached to the upper end of the bolt rod 8.
4 protrudes, and its lower end is fitted into a non-threaded portion 15. By inserting the non-threaded portion 15 into the bolt rod receiving cylindrical portion 7d and tightening it with a bolt 16, the bolt rod 8 is connected to the ground base. 7. It is designed to be planted on top of the

Further, the bolt receiver collar 9 is formed in a cylindrical shape, and the nut 9 is fixed to the inner periphery of the lower end, and the bolt rod rotation operating body 12 is rotatably attached to the inner periphery of the upper end. There is.

The bolt rod rotation operating body 12 is rotatably supported by the bolt receiving collar 10 by the bearing 11 and a retaining ring (not shown), and
A hexagonal hole slide collar is provided as a bearing portion 13 on the lower surface, and the connecting shaft 14 is slidably fitted into the collar. Reference numeral 17 is a handle of the bolt rod rotation operating body 12. When the bolt rod rotation operating body 12 is turned in the forward or reverse direction using the handle 17, the bolt rod 8 moves up or down, and the grounding base 7 attached to the lower end of the bolt rod 8 touches the floor. Traveling trolley 4 away from the floor
It is now possible to fix the position of.

In the embodiment shown in the drawings, the outriggers 6, which are the gist of the present invention, are provided near the rear wheels 4b of the traveling vehicle 4, and when the handle 17 is turned in one direction, the grounding base comes into contact with the floor. Although it is designed to fix the position of the traveling carriage 4, it is of course possible to provide it on the front wheel 4a side.

[Effects of the invention] The mobile basket stand of the invention has the configuration as described above, and in particular, the nut screwed into the bolt rod is fixedly attached to the bolt receiver collar, and the bolt rod rotation operating body is connected to the bolt. It is rotatably attached to a predetermined position of the receiving collar, and a connecting shaft provided at the upper end of the bolt rod is slidable in the axial direction on a bearing portion provided on the lower surface of the bolt rod rotation operation body, and the bolt rod rotation operation body is configured to be rotatable. Since it is fitted so that it cannot rotate relative to the body, when the bolt rod rotation operating body is rotated, only the bolt rod moves up and down, and it is possible to touch the ground without moving the bolt rod rotation operating body up or down. This has the effect of allowing the base to be brought into contact with and separated from the floor surface.
