Description

Expansion joint {EXPANSION JOINT}

The present invention relates to an expansion joint device, and more specifically, to connect rails so that the connection points between rails can expand and contract stably, guide the rails to expand and contract stably, and safely engage the connection points of the rails. This relates to an expansion joint device that can ensure structural stability by preventing bending or twisting.

In general, as modern people's leisure activities increase, interest in health and healing is naturally increasing compared to the past.

And, as the leisure life of modern people becomes more important, the importance of play culture is also increasing accordingly.

In addition, among the above-mentioned play cultures, those that allow people to exercise while enjoying a sense of speed and thrill using riding equipment as a medium are widely spread.

The riding devices include electric carts, luges, sleds, and zip lines.

In addition, in recent years, the number of people visiting skywalks and other attractions installed high up at the top of the mountain is increasing.

In order to experience the above-mentioned boarding equipment, you must climb to a certain height of the mountain, and to use the skywalk and attractions installed at the top of the mountain, you must also climb to the top of the mountain.

For this purpose, a monorail system is used that can automatically transport users to a certain height or summit of the mountain.

The monorail system may largely include a running rail installed from the starting point to the destination point, a running part that moves forward or backward along the running rail, and a passenger car mounted on the running part and roughly formed in the shape of a booth to move users.

The driving part moves forward or backward along the driving rail through a driving source such as a motor, and thus the passenger car moves from the bottom of the mountain to the top of the mountain, or from the top of the mountain to the bottom of the mountain.

And, in the case of electric carts, they run along a track formed by single or multiple rails.

However, the running rail of a conventional monorail or the rail of an electric cart has a problem in that its expansion structure is very unstable because it expands and contracts without a separate guide when expanding according to temperature changes.

In addition, because the connecting portion of the running rail of a monorail or the rail of an electric cart is twisted or rotated during expansion and contraction, this also has a very unstable problem in the expansion structure.

The pump 121 is connected to a separate water storage tank (not shown) and can supply water to the inside of the tube 119.

The measuring unit 117 measures the distance to the support 100 in real time, and when the measured distance to the support 100 becomes shorter than the preset distance, the measurement unit 117 transmits the data to an electrically connected control unit (not shown).

When a signal is transmitted from the measuring unit 117, the control unit operates the pump 121 to supply about 20% to 10% of water to the inside of the tube 119, thereby expanding the tube 119.

At this time, when the control unit receives a signal from the measurement unit 117, it can be programmed to transmit the abnormality of the support 100 to the manager's portable terminal and the manager PC.

When the tube 119 is expanded, the support plate 118 comes into close contact with the support 100 to support it.

The support plate 118 supports the support 100, and the tube 119 supports the support plate 118 at a constant weight, so even if a shock or earthquake is applied to the support 100, the support 100 can prevent it from flowing.

The amount of water filled in the tube 119 may vary depending on the size or weight of the traveling rail section 10, the auxiliary traveling rail section 20, the traveling section 30, the cart C, and the rider. there is.

Meanwhile, although not shown in the drawing, a warming unit (not shown) formed of a heating line or heating coil that operates by receiving power may be installed inside the housing 120.

The temperature measuring device is a known product capable of measuring temperature and is configured to prevent the water filled inside the tube 119 from freezing when the temperature is low, such as in winter.

For this purpose, the temperature measuring device is electrically connected to the control unit described above.

The temperature gauge measures the temperature in real time and transmits it to the control unit.

The control unit receives the temperature in real time from the temperature measuring device, and if the temperature transmitted from the temperature measuring device is a preset temperature, for example, 0°C, which is the freezing temperature of ice, it applies power to the warming unit to control the temperature of the tube 119. It is programmed to prevent the water filled inside from freezing.

Additionally, the control unit can be programmed to cut off the power applied to the warming unit when the temperature transmitted from the temperature measuring device is 1°C or higher.

Therefore, the expansion joint device according to an embodiment of the present invention can stably support the support 100, and thereby the structural structure of the first rail portions 10a and 10b and the second rail portions 20a and 20b. It is possible to protect the experiencer while ensuring stability.

Those skilled in the art to which the present invention pertains will understand that the present invention can be implemented in other specific forms without changing its technical idea or essential features. Therefore, the embodiments described above should be understood in all respects as illustrative and not restrictive. The scope of the present invention is indicated by the scope of the claims described below rather than the detailed description above, and all changes or modified forms derived from the meaning and scope of the claims and their equivalent concepts are included in the scope of the present invention. must be interpreted.
