Description

[Detailed Description of the Invention] (Industrial field of application) [0001] This invention relates to a breaker rod breakage damage prevention coupling device for a railroad crossing gate, which includes a base rod-side barrier rod and a front-end-side barrier rod. The present invention relates to a blocking rod breakage damage preventing coupling device that is coupled, bends when the blocking rod on the tip end side is pressed by an external force, and then returns to the original position.

(Prior Art) Generally, a breaker installed at a railroad crossing has a structure in which a rod-shaped blocking rod is vertically moved up and down with one end thereof as a base end. The blocking rod is made of bamboo or carbon material. It is formed into a tubular shape by, for example, and sequentially inserts thin pieces to add the pieces, and the extension parts are fixed with an adhesive tape to adjust the length to correspond to the length of the crossing.

(Problems to be solved by the invention) However, when closing the shutoff rod as the train passes, there is a time error on both sides of the railroad crossing. However, many cars, etc. are trying to pass through the railroad crossing.For this reason, while the crossing of the railroad crossing of the car, etc. is forced, despite the fact that the blocking rod of the railroad crossing on the opposite side is lowered and closed, it is forced. I often passed through and broke the barrier.

That is, in the conventional shutoff rod, since it is a structure in which thin ones are sequentially inserted and the joining portion is fixed with an adhesive tape, the joining portion is very easily broken,
The cost of the repair was great.

After that, in order to prevent such breakage of the blocking rod, when a forced external force of the car is applied, it bends according to the external force, and when the car passes and the external force disappears, it will return to its original position. Rods are now available.

However, such a breakage prevention type railroad crossing blocking rod may bend and fly out to the track side due to the reaction of external force when an automobile trapped inside the railroad crossing forcefully passes through.
If this comes into contact with a train, it could cause an accident that could injure people near the railroad crossing, which was dangerous.

In view of the above-mentioned problems, the present invention has been devised in view of the above-mentioned problems, so that the blocking rod does not break even when forced by a passing vehicle while it is crossing, and the blocking rod breakage prevention coupling device is excellent in safety. It was devised as a subject to provide.

(Means for Solving the Problem) Therefore, the present invention is a disconnecting rod breakage damage preventing connecting device for a railroad crossing breaker having a connecting device main body, a fastening tool, a towing line, and a spring. The device main body has a connecting main body and a connecting sub body, and the connecting main body is substantially rod-shaped, and has a recess formed at one end and the other end inserted into a blocking rod on the base end side of the railroad crossing barrier. The connecting sub-member has a substantially rod-like shape, and a bulging corner portion having a substantially right-angled cross section is provided at an angle of 45 degrees downward from the center toward the line side, and one end is formed as a convex portion and is loosened in a concave portion of the connecting main body. The other end is inserted into the blocking rod on the front end side of the railroad crossing barrier, one end of the tow line is fixed to the connecting sub-member, the other end is inserted in series in the connecting main body, and the spring is Attached to the tow line in the connecting main body, urging the connecting sub body toward the connecting main body, and the fastener is substantially tubular,
An anti-bending body having an L-shaped cross section is provided at the end, and is fitted onto the connecting main body and the shutoff rod to tighten and fix them.
The above-mentioned problem is achieved by the anti-bending member contacting the bulging corner portion of the connecting sub-member.

(Operation) In the above invention, however, the other end of the connecting main body is inserted and connected to the shutoff rod on the base end side of the railroad crossing breaker, and the other end of the connecting sub-body is crossed off. By inserting and connecting to the blocking rod on the tip end side of the machine, the blocking rod on the base end side and the blocking rod on the tip end side of the railroad crossing breaker are connected.

Then, when an automobile or the like trapped inside the railroad crossing is forced to press the blocking rod on the tip end side, the connecting sub body bends around the loose fitting portion between the convex portion and the concave portion as a fulcrum according to the pushing. After that, when the force of pushing through the automobile or the like disappears, the coupling sub body is urged toward the coupling main body side by the spring, and the coupling sub body returns to the original position where it is linear with the coupling main body.

The bulging corner portion of the connecting sub-member is incapable of being bent in the railroad crossing direction and the lower direction in the railroad crossing because the bulging corner portion contacts the bending prevention body of the fastener.
