The present invention relates to a conductive device of the upper mold for forming a concrete pile, and more particularly, clamping the upper mold by operating the clamp by the operation of the gear by the hydraulic cylinder when dismantling the upper mold after the curing process of the concrete pile By doing so, it is possible to achieve a clamping operation with a constant and accurate force, and to smoothly invert the upper mold with relatively little power by using a planetary reducer, thereby preventing the occurrence of backlash. It relates to a conducting device.

In general, concrete piles, such as embedded or ground poles, to securely support the upper structure, are formed in a cylindrical tube by symmetrically connecting the upper mold and the lower mold, which are divided from each other, to each other. Concrete is filled in the cylindrical tube, and the concrete of the filled state is cured and molded. Subsequently, the molded concrete pile is demolded from the upper and lower molds and sent to the construction site.

On the other hand, after the molding and demolding of the concrete is completed, the upper and lower molds are cleaned of their inner surface for reuse, and then pre-treatment is performed to apply the demolding oil or the release agent to prevent the concrete pile from sticking to the mold. Done.

In order to perform the pretreatment of the upper and lower molds as described above, the inner surfaces of the upper and lower molds must be upward to facilitate the operation. In other words, if the inner surface of the mold is downward, as the worker has to work into the bottom surface, the workability is very low, and there is a risk of safety accident of the worker.

When the upper mold forming the cylindrical tube is lifted, the lower mold does not need a separate conduction work because its inner surface is naturally upward.

However, since the upper mold is in a state where the inner surface thereof is downward from the upper side of the lower mold, the conduction operation must always be preceded before the pretreatment operation.

Conventionally, a number of workers performed the conduction of the upper mold using a lever or the like. However, in the above-described manual work, there were problems that required many workers, and also productivity was lowered, and there were various problems such as safety accidents.

As a conventional technique for improving the problems caused by the conduction operation of the upper mold depending on the manual work as described above, Utility Model Publication No. 1992-0001766 (Application No .: 1990-0003417, Designation name: Concrete pile molding) Upper mold).

1 is a schematic view showing an operating state of a conventional upper mold conductive apparatus for forming a concrete pile.

As shown in the drawing, in the related art, a plurality of pivotal arms in which two rotation shafts 1 on which pinion gears 1a are formed are arranged in parallel, and each of the rotation shafts 1 is provided with a clamp 3a. 3) is fixed, the pinion gear (1a) of the rotating shaft (1) is configured to be coupled to the rack gear (5) in conjunction with the hydraulic cylinder (not shown), respectively.

The prior art having the above configuration has the following effects.

That is, when the concrete pile 8 is cured, the mold for molding the concrete pile is transferred through the conveyor 9, and the transferred mold is disassembled and separated into the upper mold 7a and the lower mold 7b, and then the upper mold. 7a is located on the mounting base 6 by ceiling crane (not shown) or the like.

When the concrete pile 8 is lifted in the above state, the lower mold 7b is in a state where the inner surface of the lower mold 7b is in an upward state, and thus the cleaning work or the release agent coating work can be performed as it is.

Then, when the rack gear 5 is retracted by the hydraulic cylinder (not shown), the pinion gear 1a is rotated, and thus the rotation shaft 1 is rotated, and the pivot arm 3 is rotated by the rotation of the rotation shaft 1. It is located on the mounting table 6 side while being rotated. In this state, the upper mold 7a, which is in a state of being laid down on the mounting table 6, is clamped by the clamp 3a that is operated by the action of the electromagnetic force.

When the rack gear 5 is moved forward by operating the hydraulic cylinder in the above state, the pinion gear 1a is rotated, and the rotating arm 3 is rotated by 180 degrees while the rotation shaft 1 is rotated. Thus, the upper mold 7a clamped by the clamp 3a is in an inverted state.

In the above state, the inner surface of the upper mold 7a is cleaned and a release agent or the like is applied, and then the rear conduction apparatus is operated as described above, and the upper mold 7a is seated on the rear conveyor 10, and then the original position. Will be transferred to.

The prior art having the above-described configuration and working effect simply disposes the upper mold by a pivoting arm that rotates integrally with the pinion gear while clamping the upper mold with a clamp, thus disassembling and cleaning the upper mold. There was an effect that can be carried out quickly and easily, thereby increasing the productivity.

However, in the above conventional technology, there is a problem in that the clamping operation by a constant and accurate force cannot be achieved as the upper mold is clamped by the clamping action by the action of the electromagnetic force, and there is a problem in that it consumes a lot of electricity. .

In addition, in the related art, when the upper mold is inverted according to the coupling operation of the rack and the pinion gear, the upper mold falls below the center of gravity (the uppermost position), and suddenly a large load is suddenly applied to the rack. There was a problem that the pinion gear is forced to cause rapid wear of the rack and the pinion gear, and a backlash phenomenon occurs due to the wear of the gears.

In addition, there was a problem that a sudden drop of the upper mold due to the backlash phenomenon of the gears, there was a problem that the damage of the gears or the separation of the upper mold and the risk of a large safety accident according to this.

In addition to the above problem, there was a problem that a large power is required to move the rack gear having a size of 2m or more.

The present invention is devised to improve the above-mentioned conventional problems, and by clamping the upper mold by operating the clamp by the operation of the gear by the hydraulic cylinder, it is possible to achieve the clamping operation of the upper mold by a precise and always constant force It is an object of the present invention to provide a conductive device of an upper mold for forming a concrete pile.

In addition, the present invention has another object to provide a conductive device of the upper mold for forming a concrete pile that can prevent the occurrence of backlash by smoothly conducting the upper mold with relatively little power using a planetary reducer.

The front and rear rotary shafts (10a, 10b) are each coupled to the flange 12 so that several small shafts are interlocked with each other.

In general, as the concrete pile is formed longer, its upper mold also has a longer length. Therefore, the front and rear rotation shaft (10a, 10b) should also be formed long, but due to the problems caused by the vibration of the shaft, etc. can not be formed as a single integrated shaft. For this reason, several small shafts are configured to interlock with each other.
