Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a road sign raising machine, particularly to a road sign raising machine for raising crooked traffic road signs.

[Conventional technology]

Traditionally, when attempting to properly raise a crooked road sign (hereinafter simply referred to as a sign), it was done either by (a) manual labor or (b) by pulling a car, etc., using a wire rope.

[Problem that the invention aims to solve] However, the sign is often buried in the ground and the surrounding area is hardened with gravel, asphalt, concrete, etc., making it difficult to completely remove it manually.

In addition, when a car pulls a rope, the speed of pulling increases, which can cause the sign to break.Furthermore, when the sign is being pulled up by a rope, traffic may be stopped temporarily, etc. There were some dangers involved.

The present invention has been made to solve such problems, and an object of the present invention is to provide a road sign raising machine that is safe and capable of raising signs in a relatively short time with little effort.

[Means to solve the problem]

Therefore, the road sign raising machine of the present invention includes a screw for tightening a pair of tightening members sandwiching the lower part of the sign;
a lower fixture having a stop plate provided on one of the clamping members; an upper fixture having a connecting plate for connecting a screw and a push rod for tightening the pair of clamping members sandwiching the upper part of the sign; an adjustment shaft selectively fitted into a plurality of adjustment holes drilled in the pedestal; a rope stretched between the adjustment shaft and the stop plate portion of the lower fixture; and a rope swingably attached to the pedestal. It is equipped with a jack part and a push rod connected to the upper part of the jack part.

[Effect]

In the above configuration, when in use, the rope is routed to the bottom of the sign, connected to the adjustment shaft of the pier, the lower fixing device is attached, and then the upper fixing device at the tip of the push rod is tightened using the hydraulic pump with the jack part at its shortest position. It can be fixed to a sign and gradually pushed up by the jacking part to straighten the curved sign.

The figure is a side view of the same, FIG. 3 is an explanatory view showing the lower fixing device, where a is a perspective view, b is a plan view, c is a front view, d is a side view, and FIG. 4 is an upper part. FIG. 2 is an explanatory diagram showing the fixture, in which a is a perspective view, b is a plan view, c is a front view, and d is a side view.

In the figure, 1 is a stand of a road sign raising machine used to raise a curved road sign (hereinafter referred to as a sign) according to an embodiment of the present invention; 2 is a wire rope; this wire rope 2 is a stand; 1 and a lower fixture 3 that is removably attached to the lower part of the sign. 4 is a jack part that is swingably attached to the pedestal 1, 5 is a push rod attached to the upper part 4a of this jack part 4, 7 is a curved sign, and 7a and 7b are the lower and upper parts of the sign 7, respectively. So, when working, the upper part 7b of this road sign 7
The upper fixture 6 is fixed to the lower part 7a, and the lower fixture 3 is fixed to the lower part 7a. 8 is the pier 1
9 is an adjustment shaft that is inserted into the adjustment hole 8. By selectively inserting the adjustment shaft 9 into the adjustment hole 8, the mark 7 and the adjustment shaft 9 can be adjusted. The distance can be adjusted.
Numerals 10 and 11 are a pair of opposing fastening members constituting the lower fixture 3 fixed to the lower part 7a of the curved road sign 7, and in this embodiment, the fastening members are a pair of opposing fastening members. An example of a plate having an arcuate cross section will be described. 12 is a hinge provided on the pair of plates 10 and 11 having an arcuate cross section; 13 is a tightening screw;
Reference numeral 14 denotes a stop plate protruding from one plate 10 having an arcuate cross section, and is configured so that the wire rope 2 can be fastened to the lower fixture 3 by the stop plate 14. Reference numeral 15 denotes two square pipes, and the pipes 15 are joined with a bottom plate 16 with a gap for the jack part 4 to be inserted to form a crosspiece 1, and a plurality of adjustment holes 8 are formed in the crosspiece 1. It's open,
Further, the jack part 4 is swingably mounted using a mounting shaft 17. Reference numerals 18 and 19 designate a pair of plates having an arcuate cross section, which are a pair of tightening members constituting the upper fixture 6, and have a hinge 20 and a screw 21 as in the lower fixture 3. In addition, a connection plate 22 is provided in which a connection hole 22a is formed in a plate 18 having an arcuate cross section.

Reference numeral 23 denotes a connecting shaft inserted into this connecting hole 22a. Using this connecting shaft 23, the push rod 5 connected to the upper part 4a of the jack part 4 and the connecting plate 22 of the upper fixture 6 can be connected. ing. Reference numeral 24 denotes a hydraulic pump for driving the jack section 4. During use, by driving this hydraulic pump 24, pressure oil flows into and out of the jack section 4, and is pumped by the push rod 5 through the upper fixture 6. The bent sign 7 can be raised up.

In use, for example, the wire rope 2 is passed along the outside of the lower part 7a of the curved sign 7 and connected to the adjustment shaft 9 fitted into the selectively adapted adjustment hole 8, and the lower fixture 3 is slid up the lower part 7a. Fixed to prevent
Next, with the jacking part 4 in the shortest position, the upper fixture 6 attached to the tip of the push rod 5 is fixed to the upper part 7b of the sign 7, and then the push rod 5 is pushed up by the jacking part 4 to raise the bent sign 7. I'm going to go.

A bent sign 7 can be easily raised by one person, and as the pushing up speed is slow, it does not break at the bent part, and the work can be safely performed in a short time without causing traffic congestion even on a road with a lot of traffic.

In the road sign raising machine of one embodiment of this invention, a pair of tightening members 10, 11 sandwiching the lower part 7a of the curved sign 7, and a screw tightening the pair of tightening members 10, 11 sandwiching the sign 7 are provided. 13 and a stop plate 14 provided on one of the fastening members 10.
