Description

Jig for fastening safety belt [0001]

The present invention relates to a jig for fastening a worker's seatbelt to a wire of a crane during maintenance of a ceiling crane, more particularly, to a jig installed in a ceiling at an industrial site handling various heavy objects, In this case, it is possible to connect and fasten the operator's seatbelt to the wire of the crane for the safety of the worker.

Generally, a crane refers to a machine that lifts a heavy object and moves it vertically or horizontally, and is also called a crane. These cranes are used to move materials, products, or heavy objects in three-dimensionally from various factories, ports, warehouses, and so on.

The ceiling crane is the most commonly used type of crane and is installed in the ceiling of the building in the factory. The ceiling cranes are equipped with rails along walls facing each other, a beam-shaped rail running at right angles to the rails, and a trolley having a hoisting and traversing device is installed on the rails , Pulling a hook from the trolley to lift the weight.

On the other hand, if the ceiling crane fails or needs to be checked during operation, the worker climbs over the hook and performs repair or inspection. In this case, due to the flow and movement of the crane, The worker is working after connecting the seatbelt to the wire connecting the trolley and the hook through the safety hook.

However, in the method using the safety loop, since the safety loop connected to the wire is installed so as to be moved up and down along the wire with the wire passing through the wire, the role of the safety loop is not properly performed There was a problem.

(Utility Model Document 1) Utility Model Open Publication No. 0007267 (July 20, 2009, Seat Belt for Engineer)

The object of the present invention is to provide a jig for fastening a seat belt that can prevent and minimize an operator's fall in the event of a safety accident such as a fall in a work process by fixing the jig to the wire connecting the trolley and the hook.

In order to achieve the above object, according to the present invention, there is provided a seat belt fastening jig, wherein one side is hinged to each other by a jig connection member (110), and arc-shaped wire binding grooves (121, 131) A jig part (100) composed of a first jig part (120) and a second jig part (130); A jig fixing part 210 provided on the other side of one of the first and second jig parts 120 and 130 and a jig fixing part 210 provided on the other side of the other to fix the jig fixing part 210 (220); A coupling concavity (300) formed on the inner circumferential surface of the wire binding grooves (121, 131) and tightly supported on the outer surface of the wire when the wire is bound to the wire; And a safety loop connector 400 coupled to one side of the jig 100 by a jig connection member 110 and having a safety ring connected to one side thereof.

According to the safety belt fastening jig having the above-described configuration, since the jig is fixed firmly so as not to flow from the wire, the safety of the worker can be assured, thereby greatly reducing the occurrence of safety accidents, Efficient operation

Can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, a seat belt fastening jig according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The safety belt fastening jig of the present invention is formed to include the jig 100, the jig fixing means 200, the coupling concavity 300, and the safety ring coupling 400.

The jig 100 is hinged to one side by a jig connection member 110 and arc-shaped wire binding grooves 121 and 131 are formed on the other side. The first jig 120 and the second jig 120, And a jig (130).

The shape and position of the first jig 120, the second jig 130 and the wire binding grooves 121 and 131 are preferably as shown in the figure, It may be of a shape that can be fixed by sandwiching the base plate 800 therebetween.

In addition, the jig connection member 110 may be formed by any connecting member having a structure in which the first jig 120 and the second jig 130 can be hinged and pivoted, As shown in the figure, the bolt and the nut are configured to facilitate the engagement and detachment.

The jig fixing means 200 includes a jig fixing means 210 installed on the other side of one of the first and second jigging portions 120 and 130 and another jig fixing means 210 for fixing the jig fixing means 210 And a jig fixing groove 220 which is provided on the other side of the jig fixing groove 220.

The jig fixing part 210 may be a bolt and a nut separately provided from the jig part 100. The jig fixing part 220 may be a groove having a shape that allows the bolt to be inserted therethrough.

Hereinafter, the jig fixing means 200 will be described with reference to the accompanying drawings, for example, which allows a user to use the jig fixing means 200 more easily than the fixing method using the bolts and nuts described above.

The jig fixing part 210 includes a jig fixing bolt 211 hinged to the other end of one of the first and second jig parts 120 and 130, And a jig fixing nut 212 which is screwed to the fixing jig 211.

The jig fixing groove 220 is formed so that one side thereof is opened so that the jig fixing bolt 211 is fitted.

The wire 800 is inserted into the wire binding grooves 121 and 131 of the jig 100 and the jig fixing bolt 211 is rotated to be inserted into the jig fixing groove 220 and then the jig fixing nut 212 ).

In order to tighten and fix the jig fixing nut 212, it is fixed using a tool such as a wrench or a vox wrench.

In this case, if the handle 213 is provided on the outer surface of the jig fixing nut 212, the jig 213 may be used to fasten the jig fixing nut 212 without a separate tool.

Although the shape of the handle 212 is shown in the accompanying drawings as a round bar having a certain length, it may be of a shape capable of rotating the jig fixing nut 212 with the hand of an operator without a separate tool.

The coupling concavo-convex portion 300 is formed on the inner circumferential surface of the wire binding grooves 121 and 131 so as to be closely attached to the outer surface of the wire 800 to improve the binding force with the wire 800 bonded to the jig portion 100. [ .

In order to further improve the binding force, the concave and convex portions 300 may be formed so that the concave and convex portions face each other or are shifted so as not to face each other.

At this time, it is preferable that the concave-convex end portion of the coupling concave-convex portion 300 is formed in a sawtooth shape. This is to prevent the slip of the wire from being easily caused by increasing the contact area with the wire surface while allowing the concave / convex end of the concave / convex portion to come into close contact with the wire surface.

A safety collar 600 is attached to a general safety worker's seat belt 700 and a safety collar connector 400 is formed to connect the safety collar 600 to the jig 100.

The safety ring connector 400 is coupled to one side of the jig 100 by a jig connection member 110 and the safety ring 600 is connected to the other side.

Although the safety ring connector 400 is shown as having a through hole through which the jig connection member 110 is inserted and having a through hole through which the safety ring 600 can be inserted, The jig connecting member 110 may be coupled with the jig connecting member 110 by any means and may include a through hole for connection with the safety hook 600.

On the other hand, the first jig 120 and the second jig 130 are provided with anti-warp means 500.

The torsion preventing means 500 includes a torsion preventing protrusion 510 formed on the other side of one of the first and second jig portions 120 and 130 and another torsion preventing protrusion 510 When the wires 800 are coupled to the wire binding grooves 121 and 131, the anti-twist protrusions 510 are fitted in the anti-twisting grooves 520, The first jig 120 and the second jig 130 are prevented from being warped.

According to the present invention configured as described above, the safety ring connector (400) is connected to the safety ring (600) of the safety belt (700) of the worker at the time of the high-altitude operation and the wire (800) connecting the trolley and the hook of the crane The first jig 120 and the second jig 130 are fixed to each other by the jig fixing means 200 so that the wire 800 is not slipped in the wire binding grooves 121 and 131 It is used tightly.

Accordingly, the safety belt fastening jig according to the present invention is firmly fixed to the wire (800), thereby assuring the safety of the operator.
