Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a load tightening machine used for tightening cargo, and to a closed type double loosening preventer for preventing loosening of cargo handling wire wires.

In recent years, load tightening machine loosening preventers have been devised and used to prevent the loosening of load tightening machines and cargo handling wires, but these loosening preventers are designed to gain elasticity by being stretched. If false, elasticity of the steel coil spring occurs,
A gap occurs between the steel wires that form the coil spring. Also, since the coil spring itself leaks, it has the disadvantage that as the elasticity decreases, objects can get caught in the gap.

Furthermore, the coil spring itself is fully stretched due to centrifugal force,
The load tightening machine and cargo handling wire become loose, resulting in a dangerous situation in which the cargo falls.

The present invention is designed to prevent these drawbacks and obstacles, and will be explained with reference to the drawings as follows.

(1) Align the center of the circular washer /+ with the same diameter as the lit coil spring j with the center of the steel disc B with the same diameter as the steel inner pipe tube /, and hold the steel chain 2 and the neck /j'. A hole 76 is provided in which the steel ring 9 can fully rotate.

(2) Fix the end of #coil spring j to the circular washer /lI- with strong adhesive, and attach the circular washer! -/4( is welded and fixed to iW disk O.

(3) #Circular washer with the same diameter as the coil spring // and copper disc IO
In the center of the top, there is a hole where the neck of 3 is fully rotated.
2 is provided, and the hole t of the copper disk 10 is provided in a concave shape in which the old capital /3 can be buried and can be fully rotated by penetrating the copper disk 10.

(4) Steel: Fix the end of the spring j to the circular washer // with a strong adhesive, and fix the circular washer // to the inner disk of Wt by welding.

(5) 6 with neck/j! Connect the chain 2 to the i ring 9, insert the hole from the neck /j into the hole 7, and insert the copper disc IO from the hollow center of the steel coil spring 3'' through the hole /2 of the circular washer //.
Make it protrude to the 6th r.

(6) In order to prevent the neck part /j from coming off the hole 12, the end part is provided on the convex top part /3 and inserted into the concave hole.

()) A steel hook 3 is provided at the tip of the steel chain λ protruding from the sixth of the #4 circle f.

8) Insert the copper disc 10 of the constructed steel coil spring into the hollow of one of the N circular pipe flilf/, and weld and fix the steel disc B to the end of the steel circular pipe cylinder /.

(9) Insert a steel fill spring (B), which is constructed exactly the same as the steel coil spring (j) inserted into one side of the M-cylindrical tube (L), into the hollow of one side of the steel inner tube (L) from the copper disk / The other end of the M cylindrical tube / is brought into close contact with the disc 1o and fixed by welding with a copper disc /7.

(10) Attach the steel hook /9 to the tip of the steel chain protruding from the hole in the tR disc 17.

The present invention is based on the structure described above.

If you do not wish to use this, vehicles that transport cargo must be equipped with wire rope latches inside and outside the loading platform to tighten the cargo.

Normally, for general load tightening, a load tightener is placed in the center of the upper part of the load, wires are hung from the hooks installed at both ends of the load tightener, and the ends of each wire are connected to the wire latches on the loading platform. .

Then, operate the load tightening machine by hand.

Therefore, when the load tightener is tightened, the wires connected to both ends are also tightened. This is a state in which the cargo is strongly held down by the cargo tightening machine from the upper center of the cargo, and at the same time, the left and right wires are also strongly pressed from the outside of the cargo toward the inside of the cargo.

In this conventional load tightening method, the load tightening machine and wire become loose due to vibrations during travel, sinking of the load, and unbalanced movement of false loads due to centrifugal force.

This is also because in the case of multiple pieces of baggage, there are always gaps between the pieces of baggage.

Even with the use of a manual liner with the largest tightening capacity in Japan, it is impossible to prevent gaps and loosening. This is also a falsification of the synergistic effects of the gap between the loads, travel vibrations, centrifugal force, etc.

The only way to prevent this loosening is to stop the train again and again and retighten the load tightening machine, and if the entire front load is covered with a sheet, it will be difficult to retighten it in the destination area.

The method of using the present invention is to hang the hook 3 protruding from one side of the steel inner tube tube/ on one hook of the load tightening machine, and attach the cargo handling wire to the hook lq protruding from one side of the steel inner tube tube l. Connect the ends of the wire and connect the ends of the wire to the wire latches inside and outside the loading platform. Do the same for the

Then, as the load tightener is tightened by hand, the wire is also tightened. At this time, hook 3 is pulled in the direction of the load tightening machine, and one hook/9 is pulled in the direction of the wire.

Furthermore, if the load tightener continues to be tightened, the steel coil spring S11 inside the steel cylindrical tube will become compressed.
The steel wires forming the steel coil spring≠S11 are in close contact with each other. The elasticity at this time is maximum.

According to experiments, the diameter of the steel coil spring is 3;Qmm.

The wire diameter is 3, the inner diameter of the spring is 2, and the length of the spring is O.

Therefore, when the steel coil springs j1 and B are in close contact with each other, an elasticity of λton is generated by the two coil springs, and the same is true for one side of the load tightener, so a total elasticity of ≠ton is obtained.

Most commercially available load tightening machines have a tightening capacity of 0 to 500 kg, but each has a maximum tightening capacity of 2 to 3 times.

Constructed steel coil spring! , 1, and 2 are brought into close contact with each other, and when the load tightening machine continues to be tightened, the steel cylindrical tube 1 itself is tightened together with the cargo handling wire. Eventually, the manual false tightening will come to an end. At this time, the tightening capacity of the load tightening machine is at its maximum.

If the vehicle is driven in this condition, the load may shift due to sinking, gaps between the load, centrifugal force, etc. If the conventional method were used, the load tightening machine and load handling wire would immediately become loose. False loosening of the elasticity of the coil spring does not occur and is alleviated.

The steel ring 9 and the top part /3 neck part /j connected to the steel chain 3 and the steel chain 2 are connected to the circular washer // hole /, 2 and the copper disc 10
The end of the neck /j is crossed by the convex top /3 in the concave hole r in the copper disc /Q so that it does not come off from the hole in the copper disc 10. There will be no departure from.

Furthermore, since both ends of the steel inner pipe tube /7 are welded and fixed with the steel disk Otsu, /7, the
/ O and B are in close contact with both ends of the tube, so even if more force is applied, there is no need to worry about them popping out of the hollow of the tube.

The top of the steel ring 9 connected to the steel chain 2/No. 3 copper disc lS can be fully rotated by the six concave prongs, making it extremely convenient when hooking the hook 3 to the hook of a load tightening machine. It is.

Also, since the constructed steel coil spring is sometimes inserted and sealed, there is no need to worry about getting your limbs or objects caught.

Furthermore, when removing the load tightener, the elasticity of the steel coil spring 3.16 automatically disappears when the load tightener is loosened. If you can easily remove it from the spring, you can alleviate sudden damage and ivy, and steel coil springs! ;Since the steel check 2ζsr can be fully rotated in the hollow of S//, twisting and twisting of the wire can be avoided using steel coil springs! , /≠ is automatically corrected by the synergistic effect with the elasticity.

Furthermore, when an object is suspended and flies in the present invention, the suspended object does not rotate in the air.

In response to the strong demands of transportation companies and drivers, the present invention is a highly practical closed-type double loosening device that is highly safe and can prevent cargo falling accidents. be.
