Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a one-way belt lock device for removable medium to large-cargo straps,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a movable one-way belt fastening device for middle and large-sized cargo straps, and more particularly, to a middle- or large-sized cargo loaded on a freight vehicle or a ship, And more particularly, to a movable one-way belt fastening device for middle and large-sized cargo strapping that is less influenced by an external impact and stably protects and maintains the fastened state of the strapped belt.

Generally, a cargo vehicle or a cargo loaded on a ship is bound to a car body or hull through a rope and a belt so as to prevent the cargo from falling off and overturning due to shaking during transportation.

As a result, the rope and the belt used for such a strap are subjected to a strong tensile force during the strapping process.

If the strap is loose without the introduction of strong tensile force, the cargo will be overturned and damaged during the transportation process, and even the surrounding materials will be damaged.

However, as described above, since the strap used for introducing a strong tensile force to the belt is limited only by the work force (arm force) of the worker, the rope or belt used in the strap can be connected in one direction, A separate mechanical fastening device is widely used.

For the sake of understanding, the techniques disclosed in the prior art will be described as an example.

First, as shown in FIG. 10, a body fixed to a loading box of a freight vehicle; A shaft rotatably coupled to the body at both ends thereof and having a slot formed in the outer circumferential surface thereof along the longitudinal direction thereof; A ratchet wheel fixed to one end of the shaft and disposed outside the body; And a fixing means which is rotatably installed on the outer side of the body and adjusts the rotation state of the shaft so that the shaft rotates only in one direction when the ratchet wheel is engaged with the user's operation. .

This allows the fastening member (rope or belt) to be performed more quickly and easily so that the time and manpower required for the fastening member fastening operation can be significantly reduced.

11, a body main frame 6 is formed on a middle or large freight vehicle or a ship, a belt tension bar 2 is formed between the main frame 6 and the main body frame 6, And a tensioning gear 11 and is provided with a tension bar rope fixing insertion hole 12, a rope fixing bracket 3 and a strapping bolt 10 to constitute a binding apparatus main body The fixed rope is inserted into the tension bar rope fixing hole 12 and fixed by the rope fixing bracket 3 and the belt is fastened to the belt tightening bolt 10 incorporated with the strap gear 11 and disassembled And a tension bar rope fixing insertion hole 12 is formed in the fixed belt tension bar 2 so that the main frame 6 shown in Fig. 1 is fixed to one side of the vehicle body in the middle- or large- And the rope fixing bracket 3 of the tension bar rope fixing insertion hole 12 is formed, It is disclosed eojin (Document 2).

This allows the vehicle to be safely transported by preventing the belt from being loosened or loosened even if the fixing belt is repeatedly subjected to repeated relaxation and tensile action due to intermittent and continuous fluctuation during vehicle operation.

However, all of the above disclosed conventional designs have various problems due to the immaturity of the approach for problem improvement and the structural defects thereof, which will be described below in order.

First, there is a structural problem in that it is fixed to a specific part of the body or the hull but is made of a fixed structure that can be used.

That is, for practical use, it is necessary to secure a space for welding or screwing around the cargo vehicle or the car body or the hull of the cargo carrying the cargo. In order to introduce tension to the belt connected to the belt connection This is because the work can be implemented only at a nearby location from the ground where the work is inconvenient.

In particular, in the case of a freight vehicle, it was possible to introduce a tensile force to the belt connected to the belt connection only at a position where it is fixed to the outer surface of the loading space. Therefore, when carrying a cargo which occupies only a part of the loading space, There was a problem in that a substantial gap was formed and a strong strap could not be achieved in practice.

Second, there is a structural problem in that it causes local corrosion and deformation phenomenon of the body or hull as well as itself, and it does not provide a stable feeling of lengthening for a long time.

That is, since a connection or connection is made by welding or screw-tightening to various parts of the vehicle body or the outside of the hull, when a certain period of time elapses, corrosion of the welding part or the fastening screw part of the vehicle body or the hull, Or the belt can not be stably bound, and even the phenomenon of being detached from the connection point of the body or hull by the tension of the connected rope and belt frequently appears.

Third, there is a structural problem in that the durability is poor due to the fact that only the side of the rope and the belt are bound to each other.

That is, the belt that forms the cargo strap should exhibit a tensile strength capable of sustaining a load of about 3 to 6 tons or more.

This means that the belt used for the cargo strap has a tensile force of about 3 to 6 t or more when the yarn is used.

Accordingly, the mechanical fastening device for fastening such a belt can stably achieve the intended fastening only by securing the connection supporting force and durability that can firmly hold the belt from which such tension is introduced.

However, all of the above-described conventional techniques have a shaft (belt tension bar) that rotatably mounts a belt to the inside of the most fragile lower portion of the 'n' shaped main body (main frame) This is because the shaft (belt tension bar) is detached from the outside, and a part of the body (main frame) connecting the belt is deformed and damaged.

Fourth, since the vibration or impact transmitted from the rope or the belt is transferred to the shaft (belt tension bar) as it is conveyed during the transportation process, the fixed state of the strapped belt is stably protected from the external impact There was a structural problem that I could not give

That is, the rope or belt is directly connected to the shaft (belt tension bar) without interference from the surroundings, so that vibration or shock transmitted intermittently and continuously through the rope or belt This is because the shaft (belt tension bar) is shaken and the fixing means (binding gear stopper) that has been locked has often been released.

Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

In the drawings, the same reference numerals are used to designate the same or similar components throughout the drawings.

In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator.

Therefore, definitions of these terms should be made based on the contents throughout this specification.

As shown in Figs. 1 to 4, the present invention can connect and pull the belt 10 used to bind the middle or large-sized cargo c, Shaped body 110, a winding bar 120, a connecting bar 130, a ratchet wheel 140, a stopper 150, and a fixed ring belt 160.

The grid-shaped body 110 has upper and lower openings, and belt openings 112 are formed at the front and the rear of the grid-shaped body 110. The winding bar 120 is rotatably supported within the grid- And a belt slot 122 is formed on the outer circumferential surface.

The connecting bar 130 is installed and fixed in a grid-shaped body 110 at a position opposite to the winding bar 120. The ratchet wheel 140 is connected to the winding bar 120 so as to be interlocked Shaped body 110, and a fastening bolt 142 is formed on the outer surface of the body 110 so as to protrude therefrom.

The stopper 150 is rotatably installed on the outer side of the lattice-like body 110 so as to selectively control rotation of the ratchet wheel 140 by a user's operation. The fixed ring belt 160, Is connected and fixed to the connection bar 130. [

On the other hand, a fastening hole 114 is formed on the outer side of the lattice-like body 110 to enable fastening of the fixing bolt 17 so that the rotation of the stopper 15 can be selectively controlled.

Hereinafter, the operation according to the present invention will be described in detail with reference to the drawings.

FIGS. 5 and 6 are views showing the installation state of a movable one-way belt fixing device for middle and large-sized cargo straps according to the present invention.

As shown in the figure, the other end of the winding belt 10 is connected in one direction to the middle or large-sized cargo (c) mounted on the car body or hull by fixing one end thereof.

For example, after the other end of the belt 10 is inserted into the belt slot 122 of the winding bar 120 of the movable belt fixing device 100 connected to the vehicle body or the hull first by using the fixed ring belt 160, A separate ratchet wrench is inserted into the tightening bolt 142 of the ratchet wheel 140 linked to the winding bar 120 so that a strong tensile force is introduced and the stopper 150 is used And the ratchet wheel 140 is fixed to prevent rotation of the ratchet wheel 140, so that the cargo can be strapped.

The present invention capable of binding a cargo through the belt 10 is constructed in a movable structure that can be used by being connected to various parts of a vehicle body or a hull so that restrictions and inconveniences do not occur at installation points. Shaped loaded cargo can be quickly and easily bound.

That is, it is possible to easily use the fixed ring belt 160 by connecting the fixed ring belt 160 to various points around the car body or the hull where the cargo is mounted for actual use, and it is possible to use the tension applied to the belt 10 connected to the belt 10 This is because the work of introducing can be accomplished at a relatively high working height.

Particularly, in the case of a freight car, even when the cargo (c) which occupies only a part of the loading space is loaded and transported, the cargo can be connected to a ring and a groove located in the loading space of the car body,

In addition, it is possible to achieve a stable feeling of the strap, without causing local corrosion and deformation of the body or the hull, as well as the movable belt fastening device 100 itself.

In other words, it is normally stored separately and can be conveniently used by hanging the fixed ring belt 160 on the vehicle body or the hull only when the cargo is loaded, and thus the movable belt fixing device 100 itself, This is because the fixed ring belt 160 is connected to the vehicle body or the hull to provide a stable feeling of strap.

In addition, the connection supporting force and durability of the movable belt fixing device 100 can be improved, and a stable feeling of binding can be achieved.

That is, since the body of the movable belt fixing device 100 is formed in a lattice shape capable of providing excellent connection supporting force and durability, a strong tension force from the connected belt 10 is transmitted to the winding bar 120 and the connecting bar 130 The winding bar 120 and the connecting bar 130 are separated from each other and a part of the grid-shaped body 110 supporting and supporting the connecting bar 130 is not deformed or damaged.

In addition, vibration or shock transmitted from the belt 10 during the conveying process can be blocked, and the connection and fixing state of the strapped belt 10 can be stably protected from external impacts.

That is, the belt 10 connected to the winding bar 120 is connected to the belt-shaped body 110 via the belt inlet / outlet holes 112 formed at the front and rear sides thereof.

The vibration or shock transmitted to the belt 10 intermittently and continuously in the conveying process is not directly transmitted to the winding bar 120 but is blocked by the belt inlet / And the phenomenon that the ratchet wheel 140 and the stopper 150, which controls the ratchet wheel 140 and the stopper 150, are released is minimized.

In addition, a lock safety device is added to improve the safety of use.

In other words, a fastening hole 114 is formed at the outer side of the lattice-like body 110 so as to selectively fix the fixing bolt 170 to control the rotation of the stopper 150, 140 can be prevented from being released even in a situation where a strong external impact is transmitted.

For the reasons described above, it is preferable that the present invention is applied to the belt 10 used for strapping the medium-and-large-sized cargo (c) rather than the small-sized cargo.

7 to 9 are views showing a second embodiment of the present invention. The pressing bar 180 is formed on the outer side of the winding bar 120 to allow the user to pressurize the belt 10 , The belt slot 122 function of the first embodiment can be implemented instead.

Therefore, the durability of the winding bar 120 can be improved, and the connecting operation of the belt 10 can be more easily achieved, thereby improving the convenience of the operation.
