Description

Crawler fabric for emergency rescue and application thereof

Technical Field

The invention relates to the technical field of functional fabrics, in particular to a crawler fabric for emergency rescue and application thereof in heavy machinery advancing.

Background

The tank is a huge iron and steel animal which is large and heavy, and the weight of the tank is dozens of tons at all times, so that the tank can well run on hard road surfaces such as roads, and the tank is inevitably silted once meeting soft ground such as mud and marsh. However, dozens of tons of tankers are difficult to pull by the trailer and cannot find the trailer at all in field battles, so the tank soldiers think of a method for utilizing the self-rescue wood. The self-rescue wood is just one common general wood, the diameter of the self-rescue wood is generally required to be about 30 cm, and the length of the self-rescue wood is required to be 3.8 m (generally exceeding the width of the car).

When the tank takes place to become silted up and sinks on muddy road, at first will adorn the wood of saving oneself at the tank afterbody and take off, utilize the steel cable of the wood of saving oneself of carry and couple to adorn respectively on the middle part caterpillar track tooth of two tank action wheel dead ahead tracks, later use the steel cable to be fixed with the wood of saving oneself. And finally, starting the tank, hanging a gear or reversing the gear, controlling the tank to turn, and respectively tensioning the self-rescue wood. After keep tank oil feed after going straight, when the log is in the action wheel below, the tank should flame out, and the passenger need relieve the steel cable and the wood of saving oneself at this moment. Then the tank is restarted, and the first gear or the reverse gear is kept to move forward (backward), so that the tank can get rid of the trouble. These actions can be repeated if one cannot effectively get rid of the trouble. The matching use effect of the several self-rescue trees is better. However, the self-rescue timber is not standard equipment, so that a user is required to supply the self-rescue timber by himself, and the vehicle is often silted due to the fact that the self-rescue timber is not carried. In addition, for fixing the round timber by using the steel wire rope and the track pin, the method is convenient to connect and detach, but has small bearing traction force, can only be used under the conditions of light siltation and low resistance, and the round timber can slip together with the track when self rescue is carried out on deep marsh lands and deep snow lands. At this time, a log is usually connected to a track, and the log and other logs (or bundles of firewood) are connected into a wood row by using a steel wire rope, wherein the diameter of the steel wire rope is 20-30 mm. When saving oneself, the raft is dragged or is pressed below the track by a first log, and the adhesive force increases thereupon, and then the tank is got rid of poverty.

The self-rescue wood has the following defects no matter the self-rescue wood is a single wood or a connected wood row:

1. the device is not standard equipment, cannot be produced in a set manner, and cannot be supplied in a fixed time and a fixed quantity;

2. the volume is large, and the carrying is inconvenient;

3. during self rescue, the operation is troublesome and time-consuming, and manual laying and connection are needed, so that the danger in wartime is increased;

4. for the silted area with large area, deep depth and large resistance, no matter the log or the wood row can not be laid for a long distance, so that the problem cannot be solved.

The same situation also exists in equipment for civil emergency rescue and relief work, when emergency rescue is carried out on a disaster area, the road condition is often complex, once a rescue vehicle is in a silting condition, great difficulty is brought to emergency rescue, and the emergency rescue and relief work with high time urgency requirements is often fatal.

Therefore, in order to improve the tank silt-prevention equipment, save space and laying time, ensure the safety of personnel at the warhead and provide convenience for civil emergency rescue and disaster relief, the invention provides the crawler fabric for emergency rescue and the application thereof in the advancing of heavy machinery in the field.
