Description

Long-distance transport type jib cranes

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a long-haul haulage type jib crane, and more particularly, to a long haul hauling type jib crane capable of smoothly transporting and unloading a remote fishing boat or a hauler, It concerns the crane.

Generally, a jib crane is installed at the pier or the coast to transport and unload marine products, or to lift the fishing boat to land when the weather deteriorates.

The jib crane includes a post 110 vertically installed on the ground as shown in FIG. 1; A horizontal frame 120 installed to be rotatable in a horizontal direction on the upper portion of the post 110; A hoist 130 installed to be movable along the horizontal frame 120; And a driving member 140 for rotating the horizontal frame 120.

However, in the related art, the horizontal frame 120 has a cantilever structure having a short length so as to support the load of the fishing boat or the article, and the fishing boat or the article to be moored in the far off- It has a structural limit that can not be easily transported or unloaded.

Particularly in the prior art, there is no other way than to transport or unload one fishing boat or a parcel at a time, so that it is impossible to carry and haul quickly when the weather deteriorates like a typhoon.

In addition, since the horizontal frame 120 can not be fixed at a designated position in the past, when a strong wind is blown or a driving member is broken, the horizontal frame is idle, resulting in a safety accident.

Particularly, in the related art, the horizontal frame easily rotates during the replacement and maintenance of the driving member, so that a stable replacement operation can not be performed.

In addition, in the past, the hoist has always been exposed to the outside and is easily shaken, causing severe noise and damage.

Technical features of the present invention will become apparent from the following description of exemplary embodiments with reference to the attached drawings.

FIG. 3 is a cross-sectional view taken along the line AA in FIG. 2, and FIG. 4 is a cross-sectional view taken along line AA in FIG. FIG. 5 is a front view showing an operation state of the long-haul haulage type jib crane of the present invention.

The present invention relates to a post 110 installed in a direction perpendicular to a paper surface; A horizontal frame 120 installed to be rotatable in a horizontal direction on the upper portion of the post 110 and having a predetermined length so that at least two hoists 130 can move; At least two hoists (130) installed to move along the horizontal frame (120); And a driving member (140) for rotating the horizontal frame (120), the jib crane comprising:

And a fixing member 150 installed on one side of the lower part of the post 110 to operate the operator in the vertical direction to fix the upper part of the post 110 and the upper part of the horizontal frame 120 to each other.

A plurality of rails 111 are formed so as to be spaced apart from each other at a predetermined distance in the vertical direction of the intermediate portion of the post 110. A plurality of rails 111 are formed on one side of the lower frame 120, The roller 121 can be moved along the rail 111 while the horizontal frame 120 rotates, thereby ensuring stable rotation and supporting force.

A plurality of reinforcing portions 123 may be formed at a lower portion of the horizontal frame 120 so as to be connected to the rollers 121 to improve the supporting force so that the horizontal frame 120 does not strike downward.

2 and 3, the supporting frame 112 is formed on one side of the upper portion of the post 110, and the supporting frame 112 can be stopped at the rear side of the horizontal frame 120 by abutting against the supporting frame 112 A buffer 122 may be formed to prevent the buffer 122 from hitting the support 112 while the horizontal frame 120 is rotating.

At this time, the buffer 122 may be made of urethane or rubber material, so that noise and shock can be alleviated when the buffer 122 collides with the support 112.

In the present invention, the driving member 140 may be rotated at a constant speed by combining a gear and a motor to rotate the horizontal frame 120.

That is, a gear is formed on the upper part of the post 110, and a motor is provided on the upper part of the horizontal frame 120 so as to be able to rotate by engaging with the gear, so that the horizontal frame 120 can be rotated have.

In addition, the fixing member 150 is a very important structure for preventing a safety accident by preventing the horizontal frame 120 from rotating when the jib crane is not used or maintenance and standby.

As shown in FIG. 2, the fixing member 150 for this purpose includes a fixing hole 151 vertically formed on the upper portion of the post 110; A fixture 152 for vertically inserting or separating the upper portion of the horizontal frame 120 into the fixing hole 151; A pivot portion 153 formed on one side of the upper portion of the post 110; A link bar 154 which rotates in the vertical direction about the pivot portion 153 and attaches the fixture 152 to one side; An operation bar 155 formed at a lower portion of the post 110 in the vertical direction and mounted on the other side of the link bar 154; A hinge portion 156 formed on a lower side surface of the post 110; And a handle 157 which rotates in the vertical direction about the hinge part 156 and is connected to the lower part of the operation part 155 at the upper part.

At least one or more than one of the fixing holes 151 may be formed radially in a plan view, thereby preventing rotation of the horizontal frame 120 and adjusting the fixing angle.

4, when the fixing member 152 is lowered and inserted into the fixing hole 151, the fixing member 152 simultaneously connects the post 110 and the horizontal frame 120, The rotation of the horizontal frame 120 can be prevented.

Particularly, when the operator moves the operation bar 155 in the vertical direction, the rotary unit 153 serves as a central axis to rotate the link bar 154 in the vertical direction.

At this time, the link bar 154 can move the fixture 152 in the up and down direction, a moving shaft 152a is formed on the fixture 152, When the link bar 154 is rotated in a vertical direction with the long axis 154a inserted and the moving shaft 152a inserted therein, the moving shaft 152a moves along the long hole 154a, 154 and the interference can be minimized.

The operation bar 155 is formed in a vertical direction at a lower portion of the post 110 so that the operation bar 155 can be rotated in the vertical direction by rotating the knob 157 to rotate the link bar 154.

Particularly, a semicircular rotation space 124 is formed in the upper part of the horizontal frame 120 so that the operation bar 155 passes through the rotation space 124 in the vertical direction, The interference and collision can be prevented.

When the operation bar 155 includes the elastic body 155a between the lower part of the other side of the link bar 154 and the upper part of the operation bar 155 to rotate the link bar 154 in the vertical direction It is possible to maintain the angle without deformation and minimize the impact generated when the fixing member 152 is inserted into or removed from the fixing hole 151.

At this time, the elastic body 155a may be a spring as well as a synthetic resin pad.

The handle 157 rotates the worker in the vertical direction to move the operation bar 155 in the vertical direction.

A protection pipe 160 is provided at an upper portion of the post 110 and a slip ring 161 is provided at an upper portion of the protection pipe 160 so that an external power supply cable is connected to the slip ring 161 So that power can be supplied to the driving member 140.

A cover 170 is provided on one side of the horizontal frame 120 so that the hoist 130 can be inserted into the inside of the horizontal frame 120. When the hoist 130 is not used, .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Of course.
