Description

[0001] The present invention relates to a form elevating apparatus,

The present invention relates to an endless track type Euroform lifter, and more particularly, to a Euroform lifter having a rotating chain provided on one supporting structure and having an electric motor for transmitting driving force to the chain, The present invention relates to an endless track type Euroframe lifter characterized in that a beam is installed to raise a form (flow) more efficiently by using a chain rotating in an endless track.

Generally, when constructing a multi-storey structure such as an apartment or a building, a wall formwork is first installed, a ceiling slab form is installed on the top of the wall formwork, and concrete is installed to construct a wall and a ceiling slab structure. The upper layer is transferred from the lower layer to the upper layer.

In addition, when the high-rise buildings are constructed in the same manner as the upper and lower layers, such as apartment buildings, the building materials (including plywood, lumber, and pillars) used in the lower layer are usually transported to the upper layer for reuse.

Particularly, the ceiling slab formwork is mainly used as a plywood having a constant area, for example, being supported on a support in the form of a standpipe, and fixed in a flat posture in a ceiling slab area.

On the other hand, the supports for supporting the ceiling slab form are mainly used for the slabs, and are arranged in an orthogonal posture that is orthogonal to each other at the upper part of the wall formwork, that is, in a grid pattern, and the ceiling slab form is set by the vertical load, It is installed firmly so that the posture is not changed.

The ceiling slab form is installed in a ceiling slab area, and then a ceiling slab form is fixed to the ceiling slab area.

The work of installing the support may be accomplished by using a separate ladder to the ceiling slab area spaced from the floor of the worker or by climbing up the wall formwork and fixing it to the wall formwork using a fastening member such as a nail, A plurality of supports are spaced apart from each other to secure a supporting force of the supporting body.

Also, when the ceiling slab is cured after the ceiling slab is cured, the worker dismantles the supporting body and the ceiling from the bottom to the ceiling.

In addition, the dismantled ceiling slab dies are transported from the lower layer to the upper layer using the workforce of the operator.

 However, there is a disadvantage in that the worker consumes a large amount of manpower to carry the slab form to the upper layer by using the workforce, and the work efficiency also remarkably decreases.

In addition, since a safety accident often occurs during transportation of a ceiling slab form, an automatic conveying device is required to compensate for such disadvantages.

Meanwhile, in the construction of various buildings and constructions, the tie-shaped concrete wall is formed by first making a frame like a mold having a shape of a wall in the inner space, then filling and curing the concrete in the inner space, Are generally made by connecting a plurality of rectangular panel-shaped euro foam panels. Therefore, the wall is formed by connecting a plurality of euro forms to fill the concrete,

Lt; / RTI > The europod for wall construction consists of two parts which are in close contact with the front and back of the wall, and each part can be divided into an upper part and a lower part. The upper and lower ends combine a plurality of euro forms, And the front and rear surfaces are in contact with the front and rear surfaces of the wall, respectively.

These Euro forms also require a lot of manpower because they are heavier when transported to the upper part, and there are also considerable risk factors for safety accidents during the lifting process.

It is an object of the present invention to provide an infinite tracked transportation device using an electric motor, a chain, and a support, so that a form in a lower layer can be more conveniently transported to an upper layer.

As means for achieving the above object,

The tension adjusting screw part And the chain is slid upward or downward about the motor supporting bracket 21 to adjust the tension of the chain.

Further, an error factor check system for checking and warning the tension of the chain is further provided; The error factor check system includes a power source unit 101 installed to supply a necessary voltage by connecting a plurality of dry cells or mercury cells in series; A pressure error detecting unit 102 for detecting tension applied to the outer periphery of the drive sprocket to check the pressure applied by the chain and switching on the power to apply power to the circuit when one end is connected to the power source and the pressure is lower than a reference value; ; An oscillation transformer (103) for outputting a boosted AC current supplied with electricity when the tension error detecting pressure check unit is turned on; An auxiliary switch operation switching unit 108 connected to an output terminal of the oscillation transformer and turned on by an electric supply; A high voltage transformer 107a provided at an output terminal of the switching unit for operating the auxiliary switch and generating a high voltage; A first circuit connection switch (sw1) that performs a function of energizing the circuit while the iron piece is pulled by the high-voltage transformer; An alarm device power switch (sw2) for supplying power to the alarm device when the iron piece is pulled by the high-voltage transformer; The first circuit connection switch and the base end are connected to each other, the emitter end and the collector end are connected to the switching unit for operating the oscillation transformer and the auxiliary switch, and the iron piece is pulled by the operation of the high voltage transformer, When the alarm device power switch is turned off by the user, the first circuit connecting switch is interlocked and turned off. As a result, the closed circuit is broken while the switching circuit for operating the auxiliary switch is turned on and the transformer is turned on 1 circuit connection switch and a power supply switching unit 118 for turning on the alarm device power supply switch.

According to the die lifter according to the present invention constructed as described above, the operator can easily perform the work of transporting the dies 80 from the lower layer to the upper layer by being disposed inside the upper and lower layers without working on the scaffold or the railing Therefore, the operator can work safely without fear of safety accident.

In addition, since only the operation of supporting the formwork 80 in the form support beam 50 in the lower layer and removing the formwork 80 from the form support beam 50 in the upper layer can be performed, Not only can it be performed easily, but also can be performed quickly in a continuous process.

Further, since the formwork 80 can be carried without providing the openings, the burden of installing the openings can be solved, and the additional cost for double pouring, waterproofing, cleaning and the like filling the openings can be reduced.

In addition, since the worker 80 can be easily carried from the lower layer to the elevator with only two workers, the labor cost can be reduced as the number of workers decreases.

It is also possible to prevent careless handling of the formwork 80 and to prevent the formwork 80 from being lifted up along the chain 28 while being supported by the formwork beam 50, Since the mold 80 is prevented from falling down during the removal process, the mold 80 can be transported without being damaged. Therefore, in the case of a mold which can be recycled like the Euroform, the life of the mold can be greatly extended.

Further, by suitably selecting the lengths of both the support plates 10, 10, it is possible to flexibly cope with a change in the interlayer height.

FIG. 9 is a structural diagram of a tension error alarm system according to the present invention, wherein the die lifter according to the present invention comprises: both support plates 10; A driven sprocket 30 rotatably installed on the upper ends of the two support plates 10 and provided with a drive sprocket 22 and a driven sprocket 30 rotatably installed at a lower portion of the support plate corresponding to the drive sprocket, A chain 40 installed between the drive sprocket and the driven sprocket and connected to each other and a plurality of formwork support beams 50 installed at predetermined intervals over the pair of chains 40, ; ≪ / RTI >

Two spacing rods 60 may be connected to the support plates 10 so that they can be arranged vertically in parallel with each other. In other words, the gap maintaining rods 60 are arranged horizontally, and the male screws are respectively passed through the support plate 10 and fastened with nuts at both ends thereof, so that the gap holding rods 60 are arranged side by side at predetermined intervals about the two support plates 10, . Of course, the gap retaining rods and both support plates can be joined by welding, and in the embodiment of the present invention, they are joined by welding.

That is, both of the support plates and the gap-maintaining rods may be combined in a threaded manner as required, or may be joined by welding.

As described above, the drive sprockets 22 of the drive motor 40 are rotated, so that the chains 40 are rotated, and the driven sprockets 30 are rotated by the rotational movement of the chains 40 . Accordingly, the form (euro foam) supporting beam 50 connecting the chains 28 can move according to the rotational movement of the chains 40.

The support beam 50 supports the lower end of the formwork 80 and may have an angled cross-sectional structure, for example. The end of the form support pipe 50 may be welded to the chain 40 and fastened to the chain 40 by fastening means such as bolts and nuts.

Further, a device holder 70 may be further installed at the lower end of the support plates 10. That is, the equipment platform 70 serves to separate the equipment from the ground a certain distance so that the driven sprocket freely rotates.

In the present invention, the driven sprocket is freely rotatable because the driven sprocket is in contact with the ground and is difficult to rotate. Of course, the equipment cradle can be unfolded only when it is assembled by hinge coupling, and it can be folded and transported when moving between operations.

Further, a plurality of knobs 90 may be further provided on the outer surface of the gap holding bar 60. The handle 90 is installed to easily move the die lifter of the present invention. The handle 90 is formed in a substantially channel-shaped handle structure and has male threads on both ends thereof. Thus, . Of course, the handles can be welded together and are shown to be joined by welding in embodiments of the present invention.

Next, the operation of the formwork (euro foam) lifter according to the present invention constructed as described above will be described.

In order to carry a formwork (europium) 80 from the lower layer to the upper layer in order to perform the formwork for each part of the upper part of the building, the upper end of the both supporting plates 10 is supported by an interlayer slab So as to be inclined at an angle.

Since the lifter of the present invention can be handled by holding the handle 90 in the process of installing the die lifter according to the present invention as described above, the die lifter can be easily provided.

In this manner, in the state where the form lifter of the present invention is installed, one worker is placed on each of the upper and lower layers of the building, and the formwork 80 can be carried from the lower layer to the upper layer. That is, when the worker placed on the lower layer puts the form (flow form) 80 placed on the lower layer on the form beam 50 in a state in which the drive motor 20 is driven, The beam 50 is raised, and the mold 80 is also raised.

Since the formwork lifter 80 according to the present invention maintains the inclined state, the lower end of the formwork 80 is supported and the rear face thereof is lifted while being supported by the chain 40, There is no risk of being separated from the form support beam 50 in the process of ascending.

When the mold (flow path) 80 ascending according to the rotational movement of the chain 40 reaches the upper layer as described above, the operator of the upper layer releases the mold (the flow path) 80 from the form support beam 50, (Euchob) 80 can be easily and quickly transported by repeatedly carrying out the above-described process.

In the present invention, a tension adjusting device is additionally provided for adjusting the tension. In the present invention, a female thread is formed on the inner circumference of the support plate 10, and a tension adjusting screw part 1 for coupling to the female thread is provided, When the tension adjusting screw part (1) is rotated, the motor is supported by the motor supporting bracket (21) and is slid upward or downward about the motor supporting bracket (21) to adjust the tension.

In addition, the tension adjusting screw part 1 may be combined with a simple bolt 2 to rotate the bolt clockwise or counterclockwise to manually adjust the tension or automatically adjust the tension, And a drive motor 3 for turning the tension adjusting screw part leftward or rightward.

Further, the present invention is characterized in that a tension check unit 102 is provided on the outer periphery of a drive sprocket, a pressure of a chain connected to the tension error detection pressure check unit is checked to check whether the tension is appropriate, And a circuit for continuously outputting an alarm sound so as to output an alarm signal when the measurement result of the detection pressure check unit is looser than the reference value or when it is taut than the reference, and the user can not ignore the alarm.

That is, according to the present invention, the engagement state of the chain and the sprocket is checked at all times, and when the engagement pressure is lowered, the pressure check unit for detecting the tension error senses it and outputs an alarm signal. It is possible to prevent safety accidents caused by weakening the coupling force between the chain and the sprocket by continuously outputting an alarm signal.

In other words, if the chains and sprockets are loosely coupled, there is a risk of safety accidents for the workers as the chain collapses in the course of using the form (euro form) and the form falls. Accordingly, the present invention checks the coupling pressure between the chain and the sprocket to make an audible alarm sound when an error factor occurs, and even if the user ignores the alarm sound and turns off the alarm signal with the manual switch, Lt; / RTI >

In the error factor check system of the present invention, only the auxiliary switch (sw2) is exposed to the outside, and when the user turns off the auxiliary switch mechanically even though the alarm condition is not released, the auxiliary switch (sw2) So that the electricity supply can be continued.

To this end, the error factor checking means of the present invention includes a circuit power source 101, a tension error detecting pressure checking unit 102, an oscillating transformer 103, a switching unit 108 for operating an auxiliary switch, 107a, a first circuit connecting switch sw1, an alarm device power switch sw2, and a power supply holding switch 118. [

The power source unit 101 is installed to supply a necessary voltage by connecting a plurality of dry batteries or mercury batteries in series.

The tension error detecting pressure check part 102 is installed at the outer circumference of the drive sprocket to check the pressure applied by the chain, one end is connected to the power supply part, and the switching is turned on to apply power to the circuit.

When the power switch is turned on, the oscillation transformer 103 is supplied with electric power and outputs a boosted AC current.

The switching unit 108 for operating the auxiliary switch is connected to the output terminal of the oscillation transformer and is turned on by electrical supply.

The high-voltage transformer 103 is installed at the output terminal of the switching unit for operating the auxiliary switch and generates a high voltage.

The first circuit connection switch sw1 performs a function of energizing the circuit by pulling the iron piece by the high-voltage transformer.

The alarm device power switch sw2 serves to supply power to the alarm device control unit 140 and the alarm device 150 as the iron piece is pulled by the high voltage transformer.

The power supply switching unit 118 is connected to the first circuit connection switch and the base stage, and the emitter stage and the collector stage are connected to the oscillation transformer and the switching unit for the auxiliary switch operation. When the iron piece is pulled by the operation of the high voltage transformer, Pressure transformer is stopped and the user turns off the alarm device power switch, the first circuit connecting switch is interlocked and turned off. As a result, the closed circuit is turned off while the closed circuit is broken, The switching unit is turned on and the transformer is turned on so that the first circuit connecting switch and the alarm device power switch are turned on.

Hereinafter, the operation of the error factor checking means will be described.

First, when an error factor occurs in the coupling pressure between the chain and the sprocket and it becomes loose, the tension check error detection pressure check unit 102 is turned on, the DC power source is connected and power is applied to the oscillation transformer, .

The power source induced on the secondary side becomes a DC power source of a half wave through a rectifying diode, and this half wave DC power source becomes a more stable DC power source due to the charging and discharging action of the condenser.

This DC power source is applied to the anode terminal of the thyristor via the primary coil of the high-voltage transformer 103, while the DC power source charges the capacitor through the resistor. The elevated voltage passes through the diaphragm, triggers the switching unit 108 for operating the auxiliary switch, so that the node end and the cathodic end are switched so that the operation of the high-voltage transformer 107a is performed, The first circuit connecting switch sw1 and the alarm device power switch sw2 are turned on to power the alarm device control unit 140 to operate the alarm device 150. [

When the first circuit connection switch sw1 is activated, the base end of the switching unit for power supply maintenance is activated while a closed circuit is induced at the emitter end and the collector end of the power supply switching unit to turn off the power to the transformer.

That is, the voltage between the resistor 109 and the capacitor 110 is passed through the diode 120 to flow between the emitter terminal and the collector terminal of the power supply switching unit 118, and the resistance between the resistor by the bypass and the capacitor When the voltage between the resistor and the capacitor is lowered, the trigger signal to the switching part for operating the auxiliary switch is stopped and the node end and the tail end are turned off and the current does not flow to the high-voltage transformer 107a. It will stop supplying power continuously.

If the user turns off the first circuit connecting switch (sw1) or the alarm device power switch (sw2), the current flow of the closed circuit is lifted and the bias voltage flowing between the emitter end and the base end of the power supply switching part disappears, The holding switching unit 118 is turned off.

The power supply switching part 118 is turned off and the bypass voltage between the resistor and the capacitor through the diode 120 disappears and the voltage is charged in the capacitor 110. [

The charged voltage causes a break-over phenomenon of the die 111. The die signal causes the trigger signal to be output to the switching unit for auxiliary switch operation to move the iron piece, while maintaining the closed circuit and at the same time returning the output power to the alarm device control unit Make sure that alarms are made continuously.

Of course, at this time, if the pressure error check part returns to the normal state, the power supply connection is cut off, so that the alarm device power switch can be manually turned off and the alarm signal output can be cut off.

As a result, the present invention continues to output an alarm sound in a state where the error factor is not completely blocked, thereby inducing the user to completely block the error factor.
