Description

Hoist crane latching device {Apparatus for latching the hoist crane}

The present invention relates to a latching device, and more particularly, to a hoist crane latching device for interconnecting cranes so that a hoist can be moved between hoist cranes.

In general, a hoist is one of mechanical devices that lift heavy loads using a wire rope or the like and is operated by manpower or electric power. Among them, the hoist using electric power is called a hoist crane because it can lift cargo, etc. Pray.

The hoist crane is an H-beam or I-beam running rail installed horizontally on the ceiling of a factory or other structure, a conveying part transported along the traveling rail, a guide rail orthogonally fixed at the bottom of the conveying part and transported together with the conveying part, and moving along the guide rail. It consists of a hoist that transports heavy objects while moving.

However, these hoist cranes are generally used along one guide rail. Often, the hoist crane can be used on another guide rail by latching another guide rail to the guide rail. That is, a latching device capable of arranging and fixing two guide rails in a row is required in order to move a hoist provided on one guide rail to another guide rail.

That is, it is installed to be spaced apart from both sides of the web (W1) of the first guide rail (1).

At this time, one end of the first latching pin 120 can be driven forward and backward by interlocking with the driving means 110, and the other end is provided to match the length of the end of the first guide rail 1.

In addition, an interlocking member 121 may be provided to interlock the driving means 110 and the first latching pin 120.

As shown in FIG. 3 , the interlocking member 121 forms an approximate ' ┏┓ ' shape and is spaced apart from the upper surface of the first guide rail 1 and mounted thereon.

The center of the interlocking member 121 is coupled to the rod 112 of the cylinder 111, and both ends of the interlocking member 121 are coupled to one end of the pair of first latching pins 120, respectively. .

Accordingly, the first latching pin 120 may move forward or backward according to the forward movement of the cylinder rod 112 .

The second latching pins 130 are also made in the shape of a circular bar, and a pair are provided horizontally along the longitudinal direction on both sides of the second guide rail 2, respectively. That is, it is installed spaced apart from both sides of the web (W2) of the second guide rail (2).

At this time, the second latching pins 130 are arranged to face the first latching pins 120 in a line, respectively, and are provided to be able to move forward and backward horizontally.

Here, a first support boss 140 and a second support boss 150 are provided to support the first guide rail 1 and the second guide rail 2 to be installed horizontally, respectively.

The first support boss 140 and the second support boss 150 may have the same shape as shown in FIG. 4 .

The first support boss 140 is made of a flat plate-shaped support plate 141, and a pair is provided so that each may be vertically coupled to both side surfaces of the first guide rail 1. Mounting holes 142 are formed in each support plate 141 so that the first latching pin 120 can slide therethrough.

Similarly, the second support boss 150 is also made of a flat support plate 151, a pair of which are vertically coupled to both side surfaces of the second guide rail 2, respectively, and the second latching pin 130, respectively. ) is formed through which mounting holes 152 can be slid.

At this time, it is preferable that the first support boss 140 and the second support boss 150 are positioned to support the middle of the first latching pin 120 and the second latching pin 130, respectively.

Next, the first latching boss 160 and the second latching boss 170 may have the same shape as shown in FIG. 5 .

Specifically, it is made of an approximately ' ┏┓ ' shape, and is mounted and fixed to the ends of the first guide rail 1 and the second guide rail 2, respectively.

First latching holes 161 are formed below both ends of the first latching boss 160 so that the first latching pin 120 can be penetrated and inserted therein.

In addition, second latching holes 171 are formed at lower ends of both ends of the second latching boss 170 so that the second latching pin 130 can be penetrated and inserted therein.

Therefore, the first latching pin 120 is horizontally slidably supported by the interlocking member 121, the first supporting boss 140, and the first latching boss 160, and the second latching pin 130 may be horizontally slidably supported by the second supporting boss 150 and the second latching boss 170 . However, one more second support boss 150 may be provided to additionally support the second latching pin 130.

Preferably, the proximity sensor 162 may be attached to the upper surface of the first latching boss 160 .

Also, a sensing body 172 may be formed on an upper surface of the second latching boss 170 to detect when the proximity sensor 162 approaches.

Therefore, when the first guide rail 1 is moved to reach the second guide rail 2 for latching, if the proximity sensor 162 detects the sensor 172 within a certain distance, the The movement of the first guide rail 1 is stopped so that the first guide rail 1 and the second guide rail 2 come into contact with each other in a line. Then, the driving means 110 operates to perform latching.

Next, the spring 180 will be described.

The spring 180 elastically supports the second latching pin 130 so that the second latching pin 130 moves backward by being pushed by the forward force of the first latching pin 120, and then the first latching pin 130 moves backward. When the Ching pin 120 moves backward, the second latching pin 130 advances and returns by the elastic force.

To this end, a protruding step 182 may be formed on an outer circumferential surface of one side of the second latching pin 130.

The step 182 has an outer diameter larger than that of the second latching pin 130, and preferably may have a structure in which a ring-shaped locking ring 181 is attached and fixed to form the step 182.

A spring may be provided between the step 182 and the second support boss 150 .

The spring 180 may have an outer diameter smaller than that of the step 182 and may use a compression coil spring.

Therefore, when the second latching pin 130 moves backward, the spring 180 is compressed, and when the external force is removed, the second latching pin 130 moves forward due to the elastic force of the spring 180 . At this time, it is preferable to have a structure in which both ends of the spring 180 are coupled to the second support boss 150 and the step 182 so that the second latching pin 130 does not protrude.

Hereinafter, the movement limiting unit 200 will be described with reference to FIGS. 6 and 7 together.

The movement limiting unit 200 is a first movement limiting unit 201 that restricts or permits the movement of a hoist (not shown) moving on the first guide rail 1 and moves on the second guide rail 2 A second movement limiting unit 202 for restricting or permitting the movement of the hoist may be further included.

First, the first movement limiting part 201 is located between the first supporting boss 140 and the first latching boss 160, and largely includes a first hinge pin 210, a first stopper 220, a first It may be configured to include a lever 230.

The first hinge pin 210 has an axial shape and is fixed by penetrating the web W1 of the first guide rail 1 horizontally.

The first stopper 220 is rotatably coupled to both ends of the first hinge pin 210 .

The first stopper 220 may have various shapes, but may have a horseshoe shape as shown, but is not limited thereto. However, the surface in contact with the hoist may be a disk or polygonal plate having a certain area. In addition, an elastic material such as rubber may be used to prevent impact.

At this time, the upper part of the first stopper 220 is coupled to the first hinge pin 210 so that the first stopper 220 is positioned vertically downward by its own weight, and the hoist moves along the first guide rail 1 ) It is possible to limit movement along the lower flange (F1).

In addition, a first lever 230 is formed upwardly extending above the first stopper 220 . Therefore, since the first lever 230 can rotate together with the rotation of the stopper 220, the first stopper 220 can be rotated by pushing the first lever 230.

A first pushing bar 122 is further coupled to the front end of the first latching pin 120 to push the first lever 230 .

The first pushing bar 122 may pass through the first latching pin 120 and be coupled at a right angle, and an inner end of the first pushing bar 122 may collide with the first lever 230. is in a position

Therefore, when the first latching pin 120 moves forward, the first pushing bar 122 pushes the first lever 230, so that the first stopper 220 blocking the hoist moves the first hinge pin It rotates about 210, allowing the hoist to move.

Meanwhile, the second movement limiting part 202 is located between the second supporting boss 150 and the second latching boss 170, and largely includes a second hinge pin 240, a second stopper 250, and a second lever. It may be configured to include (260).

The second hinge pin 240 has an axial shape and is fixed by penetrating the web W2 of the second guide rail 2 horizontally.

The second stopper 250 is rotatably coupled to both ends of the second hinge pin 240 .

The second stopper 250 may have a shape similar to that of the first stopper 220, but a surface in contact with the hoist is opposite to that of the first stopper 220.

In addition, the upper part of the second stopper 250 is coupled to the second hinge pin 240 so that the hoist moves along the second guide rail 2 in a state where the second stopper 250 is positioned vertically downward by its own weight. It is possible to limit movement along the lower flange (F2) of.

However, in order to allow the second stopper 250 to rotate in the opposite direction to the first stopper 220, a second lever 260 extends downward at the bottom of the second stopper 250.

The second lever 260 may rotate along with the rotation of the second stopper 250, and may rotate the second stopper 250 by pushing the second lever 260.

A second pushing bar 132 is further provided at the front end of the second latching pin 130 to push the second lever 260 . Here, since the second pushing bar 132 needs to be positioned lower than the second latching pin 130 in order to push the second lever 260, a separate bracket 131 is provided to the second latching pin 130. and the second pushing bar 132 is coupled to the lower end of the bracket 131 in a direction orthogonal to the second latching pin 130.

Therefore, when the second latching pin 130 moves backward, the second pushing bar 132 pushes the second lever 260, so the second stopper 250 moves the second hinge pin 240. It rotates to the center, allowing the hoist to move along the second guide rail (2).

Hereinafter, the operating process of the present invention will be described with reference to FIG. 8 . 8 is an operating state diagram of the present invention.

The worker moves the first guide rail 1 to which the hoist is mounted and places the hoist in a line with the second guide rail 2 to be delivered.

At this time, it may be automatically stopped by the proximity sensor 162 and the sensing body 172.

Immediately, the driving means 110 is operated to advance the first latching pin 120 .

The first latching pin 120 advances and is inserted into the second latching hole 171 of the second latching boss 170 while pushing the second latching pin 130 . Therefore, the first latching pin 120 penetrates the first latching hole 161 and the second latching hole 171 at the same time to connect the first guide rail 1 and the second guide rail 2 and It will be fixed (locked).

Also, the second latching pin 130 moves backward while being pushed, and the spring 180 is compressed.

Here, as the first latching pin 120 advances, the first pushing bar 122 pushes the first lever 230 to rotate the first stopper 220 clockwise (see the drawing), and at the same time As the second latching pin 130 moves backward, the second pushing bar 132 pushes the second lever 260 to rotate the second stopper 250 counterclockwise.

That is, the first stopper 220 and the second stopper 250 positioned vertically downward are positioned horizontally.

In this state, the hoist moves along the first guide rail 1 and crosses over to the second guide rail 2 to complete the transfer.

When the delivery is completed, the driving means 110 operates to move the first latching pin 120 backward and return it to its original position, and the second latching pin 130 moves forward by the spring 180 and returns to its original position.

In addition, the first stopper 220 and the second stopper 250 are also reversely rotated by their own weight to return to their original positions, again limiting the movement of the hoist.
