The present invention relates to a locking device for an unloading machine having wind resistance, and more particularly, to prevent the departure or deformation of the pylon structure from the portal structure of the continuous unloading machine even when strong wind blows, and to maintain a stable coupling state. .

In general, a continuous unloader (CSU) that unloads raw materials (coal, grain, cement, minerals, etc.) from a berthing vessel to a pier is a boom and counter on a body structure settled on the surface of the pier. A weight boom is installed, a bucket elevator is installed at the end of the boom, and a gantry conveyor is disposed along the longitudinal direction of the main body structure.

 These bucket elevator type unloading machines are assembled and tested by the manufacturer, then shipped to the ship as fully assembled, and are transported to the pier after completing special parking work for sea transportation.

On the other hand, the continuous unloading machine is large in size and weight, and the shape and structure are not stable, so a special high design is required safely in consideration of marine conditions and ship conditions.

At the end of the countweight boom, a block support was installed to support the high-load concrete block to maintain the load balance.

However, the conventional continuous unloading machine transport device is very unstable in the nature of the structure having a large load at high altitude when the external force is strong in the vertical direction during the sea transport.

In addition, if the weather conditions worsen or abnormal external force is applied during sailing, there was a problem that can cause a large accident.

In order to solve such a problem, conventionally, as shown in FIG. 1, a pylon structure 20 is rotatably coupled to an upper portion of the portal structure 10, and the pylon structure 20 may be rotated. The locking pin 30 is inserted and installed inside. The locking pin 30 penetrates through the interior of the hollow pylon structure 20 to penetrate the portal structure 10 and is detachably coupled thereto.

In addition, the upper end of the locking pin 30 is hinged to the lever 40 in the horizontal direction, the end of the lever 40 is provided with a connecting member 41 in the vertical direction.

In addition, one side of the pylon structure 20, that is, the support member 42 is fixedly installed at a distance from the side of the connection member 41, and the connection member 41 is disposed at the end of the support member 42. Shanghai Shanghai is possible. The connection member 41 is coupled to the up and down movement relative to the support member 42, the long hole (41a) is formed in the connecting member 41, the connecting member 41 in the long hole (41a) The coupling pin 43 is integrated with the coupling member 43 so as to be able to move up and down in the long hole 41a. The coupling pin 43 in the long hole 41a is supported by the chain 44 to support the member 42. Combined with.

A weight 50 is provided at the end of the lever 40.

Here, the installation position of the locking pin 30 is located eccentrically from the central axis 21 of the pylon structure 20, as shown in FIG.

In the conventional locking device having such a configuration, as shown in FIG. 1 in order to keep the continuous unloader firmly in a fixed state when a strong wind is blown by a typhoon or the like, the locking pin 30 has a pylon structure 20. When it is inserted into the portal structure 10 in a fixed state penetrating through the interior thereof, as shown in Figure 2, it is not rotated in relation to the rotation center axis 21 is installed eccentrically.

If, in order to make the pylon structure 20 in a rotatable state, the locking pin 30 may be released from the coupling state to the portal structure 10 again. This may be achieved by first moving the connecting member 41 downward by an external force. , The lever 40 is rotated about the hinge portion 45, 31 while the locking pin 30 is raised in the interior of the pylon structure 20, accordingly coupled state with the fixed portal structure (10) It is released. Therefore, the pylon structure 20 is rotatable about the central axis 21.

However, the conventional locking device installed on the pylon structure 20 has a narrow gap between the rotational coupling portion between the portal structure 10 and the pylon structure 20, so that it is difficult for the worker to see from the outside with the naked eye. It is difficult to enter 30) through the pylon structure 20 to the upper part of the portal structure 10, and furthermore, if foreign matter gets stuck in the rotational axis position or freezing occurs in winter, the rotation is not performed well. The locking pin 30 is not easily coupled and separated, such as problems occurred.

As shown in the figure, in the unloading machine consisting of the portal structure 100 and the pylon structure 110, the inside of the pylon structure 110 is provided with a rotating means 120, the upper portion of the portal structure 100 The fixing means 130 is provided.

Basically, the portal structure 100 is in a fixed state, and the pylon structure 110 is in a rotatable state.

The rotation means 120 is a structure in which the rotating shaft 121 is fixed to the segment 111 of the pylon structure 110, and the shield member 122 is wrapped around the rotating shaft 121 to be rotatable. to be. In addition, the shield member 122 may be integrally coupled with the rotation shaft 121 so that the rotation shaft 121 may be rotated in the segment 111 of the pylon structure 110.

In addition, the fixing means 130 is coupled to the connector 132 which is detachably provided between the brackets 131 installed at intervals on both sides of the upper portion of the portal structure 100, and coupled through the connector 132 It is a structure provided with the shaft 133. The connector 132 and the shaft 133 are fixed through the binding pin 134.

In addition, the rotating means 120 and the fixing means 130 is connected by the lever 140, so that the fixing means 130 is rotatable around the rotating means 120.

In addition, the upper portion of the rotating means 120 has a structure that is rotatably provided with a fixing lever 123 to stop the shaft 133 of the fixing means 130 is raised at intervals.

In addition, the segment 111 of the pylon structure 110 is a structure rotatably provided by the bearing member 150. More specifically, as shown in FIG. 4, the segments 111 constituting the pylon structure 110 are vertically and horizontally provided to be rotatable from the portal structure 100 underneath. At this time, the portal structure 100 is maintained in a fixed state.
Here, the bearing member 150 is provided between the connecting member (110a) and the connecting member (100a) of the portal structure 100 is formed extending from the segment 111 of the rotating pylon structure (110). The bearing member 150 is composed of a rotating part 151 and a fixing part 152, and a plurality of rollers 153 for smooth rotation are provided between the rotating part 151 and the fixing part 152.

As shown in FIG. 3, the present invention having such a configuration is locked in the state in which the shaft 132 is inserted between the brackets 131 of the fixing means 130, and thus, the pylon structure from the fixed portal structure 100. The rotation operation of 110 is not made.

Therefore, even if a strong wind blows due to the weather change, it is possible to prevent a phenomenon such as the fall of the pylon structure located above the portal structure among the unloading structures.

On the other hand, if you want to release the locked state is to remove the shaft 133 in the fixing means 130 from the bracket 131, first through the handle 141 connected between the two lever 140, When lifted up, the shaft 132 sandwiched between the brackets 131 is about to be separated, and at this time, the shield member 122 rotates about the rotation shaft 121 of the rotation means 120 located on the pylon structure 110. Therefore, as shown by a dotted line in the drawing, it is possible to easily rotate the shaft 132 to the top. Then, the fixed lever 123 installed in the segment 111 of the pylon structure 110 is rotated to maintain the fixed state without falling forward of the shaft 132.

In this state, since the pylon structure 110 is rotatable from the portal structure 100, the pylon structure 110 may be rotated as necessary.
In other words, as shown in FIG. 4, when the portal structure 100 is fixed, when the pylon structure 110 located above the portal structure 100 is rotated, the connection member 110a and the bearing member ( Since the rotation part 151 constituting the 150 is integrally coupled through the bolt 160, the rotation part 151 is rotatable based on the fixing part 152 installed at the lower part thereof. In this case, the roller 153 allows the rotating part 151 to smoothly rotate based on the fixing part 152. This serves as the ball of the ball bearing member.
Since the fixing part 152 of the bearing member 150 is integrally coupled with the extension member 100a of the portal structure 100 through the bolt 161, when the pylon structure 110 is rotated, it is always in a fixed state. To maintain. At the time of rotation of the pylon structure 110, the rotating means 120 is provided in the segment 111, so that it can be rotated at the same time.

As described above, the present invention provides a locking device in a pylon structure of a continuous unloading machine that is difficult to maintain a high crunch state while forming a complex structure when a strong wind such as a typhoon blows due to bad weather, so that locking and releasing are easy and sure locking state. It can maintain the effect that can withstand typhoons.

In addition, the locking device overcomes the disadvantages that are difficult to match during the locking operation as in the related art, and thus is easily adjusted to the locking position while being easily moved to the upper or lower portion, thereby making the operation easier.
