Chain pin replacement device for continuous unloading machine {A CSU CHAIN PIN REMOVAL DEVICE}

The present invention relates to an apparatus for replacing a chain pin, and more particularly, to improve work safety while improving work safety by reducing a range of manual work during chain pin replacement and increasing the work range of electric mechanization.

In general, a continuous unloader 10 (CSU: Continuos Ship Unloader), which unloads raw materials from a ship anchored at a coal power plant, a steel mill, or a pier, has a main body structure which is settled on the surface of the pier as shown in FIG. 11) a boom 12 and a counter weight boom 13 are installed, a bucket elevator 14 is installed at the end of the boom 12, the longitudinal direction of the main body structure 11 The gantry conveyor (20, gentry conveyor) is formed according to the form.

In such a continuous unloading machine 10, the bucket elevator 14 is located in the hold 2 of the ship anchored at the pier, and the coal inside the hold 2 is circulated by the circulation of the bucket 14a. The raw material cargo is excavated and then unloaded to two wharf conveyors 40 via a two-way chute 30 at a head of a kentry conveyor 20.

On the other hand, a plurality of buckets (14a) are attached to the chain at regular intervals and is circulated by the chain drive, the chain supporting the bucket (14a) in this way to replace the chain pin of the connecting portion at regular intervals do.

That is, in the related art, after one or two workers manually install a separate jig on a worktable of a certain height for the chain pin replacement work, the chain pin replacement work is performed while the chain is seated and fixed on the jig. .

However, in such a conventional work process, due to the difficulty of working by manually installing a high-weight jig of 180kg, and because the height of the work platform is not adjusted, it is difficult for two or more people to work on a narrow work table. There was a problem such that a risk of a safety accident occurs.

The present invention has been proposed to improve the problems in the above-mentioned conventional chain pin replacement work, the height of the worktable can be adjusted and the work convenience by providing a replacement device that can be mechanically fixed the chain for replacing the chain pin And to ensure safety.

Chain pin replacement apparatus of the present invention for achieving the above object, the worktable is to be mounted on the chain to be worked; A support column installed in a vertical direction to support the work table; A lower jig fixed to the upper surface of the work table; An upper jig configured to be liftable from an upper part so as to be paired with the lower jig to fix the chain; Jig adjustment cylinder for adjusting the height of the upper jig; And lifting means for driving the work table up and down along a support column.

In addition, the chain pin replacement device of the present invention, the lower plate; A worktable supported and installed by a support pillar at an upper portion of the lower plate; A lower jig fixed to the upper surface of the work table; An upper jig configured to be liftable from an upper part of the lower jig to fix a chain placed on an upper surface of a work table; Jig adjustment cylinder for adjusting the height of the upper jig; Elevating means for elevating and driving the work table along a support column; Characterized in that the configuration including; a movable pedestal is configured to the bottom to enable the movement of the lower plate.

The chain pin replacement device of the present invention, the chain pin replacement operation in the continuous unloader was made by the manual labor of the operator can be made more easily, thereby improving the work safety and greatly reduce the working time Effect.

In particular, it is possible to easily remove the chain pin by releasing the lateral force of the chain through the secondary worktable lift in the state fixed to the jig through the primary height adjustment.

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

First, looking at the configuration of the chain pin replacement apparatus according to the present embodiment, the lower jig 51 and the upper jig 52 for fixing the chain 100 is configured on the work table 50 to be replaced, among which The upper jig 52 has a structure capable of lifting and lowering by the jig control cylinder 53, one side of the pin removal cylinder 54 is mounted together with the operation rod 54a. Two concave portions 51a and 52a are formed in pairs on opposite surfaces of the lower jig 51 and the upper jig 52 so that the chain 100 may be seated and fixed.

A support pillar 55 for supporting the work table 50 to be movable up and down is installed on the lower plate 60 in a vertical direction, and the support pillar 55 is a rotation gear 59a driven by a driving motor 59. Is mounted, and the engaging portion 58 engaged with the rotational gear 59a is fixedly installed on the worktable 50, and thus the worktable 50 can be lifted and lowered by driving the drive motor 59. .

On the other hand, the movable pedestal 70 is used as a moving means for the movement of the work table 50.

The movable pedestal 70 is supported by a conventional X-link 71 that is intersected about a hinge axis, and one side of the X-link 71 is provided with a hydraulic cylinder 72 for lifting and lowering. There can be seen that four moving wheels 73 are mounted on each corner side.

In the figure, reference numeral 56 denotes a hydraulic distribution valve, 61 denotes a hydraulic pump, and 62 denotes a hydraulic control remote controller.

The effect of the use of the present pathogen chain pin replacement device constituting such a configuration will be described.

First, the foot frame part of the CSU is seated on the ground, and then the bucket of the chain pin part to be replaced is removed.

Thereafter, the work table 50 of the present invention is moved to a continuous unloading work position where the work is to be made by the movable wheel 73 in a state seated on the movable pedestal 70, and after the position movement, the work table 50 is The hydraulic cylinder 72 is driven to be approximately aligned with the height of the chain 100 to drive the X link 71 upward.

When the height adjustment of the primary work table 50 is made as described above, the upper part of the upper jig 52 is driven by driving the jig control cylinder 53 after the bucket 100 is mounted on the lower jig 51. By lowering the chain 100 is fixed, in this case, because the lateral axial force due to the load acting on the chain 100 acts to eliminate the lateral axial force due to the chain weight of the secondary work table ( 50) Ascending drive is performed.

That is, when the drive motor 59 is driven while the chain 100 is fixed by the upper and lower jigs 51 and 52, the work table 50 is engaged with the rack portion 58 and the rotation gear 59a. By increasing the height of the chain tension can be eliminated.

In addition, the chain pin 101 is removed by the pin removal cylinder 54 in the stable fixing of the chain 100.

That is, at this time, the chain pin 101 is removed by being pushed by the forward operation of the operation rod 54a. In this case, the chain 100 is operated because both sides are caught in the recesses 51a and 52a. It can be seen that the support of the reaction force against (54a) can be made so that a stable pin removal operation can be made.

In addition, when the lower jig 51 is installed in accordance with the center height of the chain pin 101 during manufacturing, the centering process may be omitted during the operation.

In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the structure of the chain pin replacement device of the present invention may be variously modified and implemented by those skilled in the art.

For example, in the above embodiment, a state in which the work table 50 is mounted and used on the movable pedestal 70 has been described and illustrated, but the work table 50 may be used separately or may be manufactured integrally with the movable pedestal 70. Will be.

It should be understood, however, that such modified embodiments are not to be understood individually from the spirit and scope of the invention, and such modified embodiments are intended to be included within the scope of the appended claims.
