Description

Technical Field

[0001] This invention belongs to the field of heavy-duty airdrop technology, and in particular, it is a traction rope protection device suitable for heavy-duty airdrop systems. Background Technology

[0002] The existing airdrop systems in China use a single-layer, relatively thin protective sleeve for the tow rope. When airdropping heavy equipment, the tow rope will rub against the aircraft floor when the parachute is inflated and the tow rope pulls the airdropped item, causing the protective sleeve to break and the main body of the tow rope to be exposed and easily worn. Summary of the Invention

[0003] The purpose of this invention is to provide a tow rope protection device suitable for large-tonnage airdrops, protecting the tow rope from wear and tear during the airdrop process.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a traction rope protection device suitable for a large-tonnage heavy equipment airdrop system, comprising a protective sleeve main body, a buckle reinforcing belt, a reinforcing belt, a buckle, a protective sleeve reinforcing cloth one, and a protective sleeve reinforcing cloth two;

[0005] The main body of the protective cover is equipped with several buckle reinforcement straps, which are sewn around the longitudinal direction of the main body of the protective cover.

[0006] Several buckles are symmetrically provided at both ends of the main body of the protective cover. The reinforcing strap is pressed onto the buckles and sewn onto the main body of the protective cover.

[0007] The protective sleeve reinforcement fabric one and the protective sleeve reinforcement fabric two are sewn onto the inside of the main part of the protective sleeve.

[0008] The main part of the protective sleeve has a cylindrical structure.

[0009] Two rows of floral stitches are sewn at the buckle position.

[0010] Compared with the prior art, the present invention has the following significant advantages: (1) The tow rope protection device is suitable for airdropping large-tonnage cargo. (2) The tow rope protection sleeve protects the main part of the tow rope from damage when it rubs against the aircraft floor during the airdrop process. Attached Figure Description

[0011] Figure 1 This is a diagram of a protective case. Figure 2 This is a diagram of a traction rope. Detailed Implementation

[0012] This invention is primarily applied to the protection of the tow rope during heavy-duty airdrops in my country. It designs a tow rope protection sleeve to protect the tow rope when it pulls the airdropped equipment off the aircraft.

[0013] The traction rope protection device consists of a main protective sleeve 1, a buckle reinforcement band 2, a reinforcement band 3, a buckle 4, a protective sleeve reinforcement fabric 1 5, and a protective sleeve reinforcement fabric 2 6.

[0014] The traction rope protection device is fitted over the main body of the traction rope to protect it. It is secured to the main body of the traction rope with a cable tie.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] The traction rope protection device consists of a main protective sleeve 1, a reinforcing buckle 2, a reinforcing strap 3, a buckle 4, a first reinforcing fabric of the protective sleeve 5, and a second reinforcing fabric of the protective sleeve 6. The traction rope consists of a main traction rope 7, a first cable tie 8, a protective sleeve 9, and a second cable tie 10.

[0017] Combination Figure 1 , Figure 2 The main body 1 of the traction rope protection device is a cylindrical structure with a length of 575m. Reinforcing buckle straps 2 are sewn at intervals of 14.8m, 5.6m, 6.7m, 6.7m, 5.6m, and 14.7m from one side of the protective sleeve. The reinforcing buckle straps 2 are sewn around the longitudinal direction of the main body of the protective sleeve, with a buckle length of 25mm and a distance of 10mm from the edge of the protective sleeve. With the reinforcing buckle straps 2 as the center of symmetry, a 100mm horizontal opening is left on the main body 1 of the protective sleeve to allow the buckles on the main body 7 of the traction rope to pass through the protective sleeve.

[0018] First, place the four buckles 4 symmetrically at both ends of the main part (1) of the protective cover, then press the reinforcing strip 3 onto the buckles 4 and sew it onto the main part 1 of the protective cover. Then sew two rows of floral stitches at the buckle 4 positions to strengthen the connection.

[0019] The combination of protective sleeve reinforcement fabric 1 (5) and protective sleeve reinforcement fabric 2 (6) involves cutting two pieces of the main body material of the protective sleeve with lengths of 8m and 2.8m respectively, and sewing them directly onto the inside of the main body of the protective sleeve to increase the wear resistance of the protective sleeve.

[0020] The main part 7 of the traction rope has 5 numbered loops and one pin loop. Thread the protective sleeve onto the main part 7 of the traction rope, extend the numbered loops and the pin loop from the corresponding openings of the protective sleeve, and use cable ties 2 10 to pass through the loops and numbered loops on the reinforcing strap 2 of the protective sleeve to secure the protective sleeve.

[0021] Use cable ties 8 to thread through the loops on the main body of the traction rope and the buckles on the protective sleeve to secure the protective sleeve to the traction rope.

[0022] Work process

[0023] The navigator presses the release button, and the tow parachute falls from the aircraft lock. The release cord opens the brake flaps on the top of the tow parachute, which inflate fully, straightening the tow cords and the tow parachute.

[0024] Once the chaff is fully inflated, the pulling force of the chaff cuts the shear pin securing the tow lock on the cargo platform. The locking rod of the tow lock disengages from the socket in the central guide rail, freeing the cargo platform from its constraint. The chaff then pulls the cargo platform out of the aircraft cargo hold. During this process, the tow rope will rub against the aircraft floor due to airflow. To prevent damage to the tow rope from friction, a protective sleeve is fitted over it.

[0025] After nearly 10 tests, the navigator presses the release button, the tow parachute falls from the aircraft lock, the parachute release line opens the brake flap on the top of the tow parachute, the brake flap inflates fully, and the tow line and tow parachute are straightened.

[0026] Once the chaff is fully inflated, the pulling force of the chaff cuts the shear pin securing the tow lock on the cargo platform. The locking rod of the tow lock disengages from the socket in the central guide rail, freeing the cargo platform from its constraint. The chaff then pulls the cargo platform out of the aircraft cargo hold. During this process, the tow rope rubs against the aircraft floor, and the tow rope protective sleeve prevents damage to the tow rope, thus achieving the design objective.
