Description

Beam extractor moving device and beam extractor having the same {Apparatus for moving beam extractor and beam extractor having the same}

The present invention relates to a beam extractor for pulling out an H beam embedded in the ground, and more specifically, to a beam extractor moving device that can easily and conveniently move a beam extractor that has completed beam extraction to the next working position, and a beam extractor equipped with the same. It's about.

In general, in civil engineering work, protective walls are installed to prevent earthen walls from collapsing due to earth pressure during excavation work, and water blocking work is also carried out to block the inflow of groundwater.

A commonly used method for such earth retaining and water blocking is to place a plurality of H-beams at regular intervals, insert wooden earth plates between adjacent H-beams to install an earth retaining structure, and then install a retaining structure behind the earth retaining structure where a space is formed. A method of stabilizing the ground by filling in the soil is mainly used.

Since these H-beams are expensive equipment and are temporarily installed structures, when the construction of the underground structure is completed, the work of pulling out and recovering the H-beams embedded in the ground must be carried out.

However, since the H-beam is buried deep underground and cannot be pulled out by manpower, a puller is usually used that uses a hydraulic cylinder to pull out the H-beam embedded in the ground with strong upward pressure.

Figure 1 is a perspective view of a general beam extractor in use. As shown, the conventional beam extractor includes a base 10 placed on the ground, left and right raising and lowering cylinders 20 installed on the base, and left and right raising and lowering cylinders. It includes rotary holders installed to extend from the upper part of (20) toward the H beam (H).

In addition, the rotary holder consists of a cylinder 30 rotatably coupled to the side of the left and right raising and lowering cylinders 20, and a left and right pressure plate 40 rotatably coupled to the end of the rod of the cylinder 30, respectively. It is composed.

Therefore, when the rods of the left and right raising and lowering cylinders 20 are pulled out while the left and right pressure plates 40 are pressed in close contact with both sides of the H beam (H), the cylinder 30 of the rotary holder rises and the H beam (H) rises. It is pulled out from the ground.

However, the conventional H-beam dispenser as described above must be moved for the next work after the drawing work is completed, but due to its high weight, there is an inconvenience in that it must be moved by hanging it using heavy equipment such as a crane.

Accordingly, the work speed slows down and various safety accidents often occur during the process of hanging and moving the crane, so improvements are required.

As shown, the beam extractor moving device according to the present invention is a beam extractor (1). ), the first cylinder 100 to the fourth cylinder 400 installed on the base 10, the lifting cylinder 500 and the lifting cylinder coupled to the first cylinder 100 to the fourth cylinder 400. It includes a wheel (600) coupled to (500).

The beam extractor 1 to which the present invention is applied is a general beam extractor and is substantially the same as the above-described beam extractor, so detailed description here will be omitted.

The first cylinder 100 is installed on the front left side of the base 10. The first cylinder 100 is installed to expand and contract as the rod is pulled out or retracted to the left.

The second cylinder 200 is installed on the front right side of the base 10. The second cylinder 200 is installed to expand and contract as the rod is pulled out or retracted to the right.

In this way, the first cylinder 100 and the second cylinder 200 are installed at the front end of the base 10 to face opposite directions.

The third cylinder 300 is installed on the rear left side of the base 10. The third cylinder 300 is installed to expand and contract as the rod is pulled out or retracted to the left. The third cylinder 300 is installed in a straight line with the first cylinder 100 in the front-to-back direction.

The fourth cylinder 400 is installed on the right side of the rear end of the base 10. The fourth cylinder 400 is installed to expand and contract as the rod is pulled out or retracted to the right. The fourth cylinder 400 is installed in a straight line with the second cylinder 200 in the front-to-back direction.

In this way, the fourth cylinder 400 is installed at the rear end of the base 10 to face opposite directions.

Accordingly, the first cylinder 100 to fourth cylinder 400 has an overall square shape and is installed along the upper edge of the base 10 and is located inside the first cylinder 100 to fourth cylinder 400. The left and right raising and lowering cylinders 20 of the beam extractor 1 and the rotary holder 30 are located there.

The lifting cylinder 500 is vertically coupled to each rod end of the first to fourth cylinders 100 to 400, and is connected to the beam extractor 1 along the rods of the first to fourth cylinders 100 to 400. It moves left and right until it is located outside the base 10.

Meanwhile, the first to fourth cylinders 100 to 400 are preferably installed inclined upward.

In this case, the vertical load of the lifting cylinder 500 applied to the rods of the first cylinder 100 to fourth cylinder 200 can be effectively distributed, and the first cylinder 100 to fourth cylinder 400 ) can be smoothly coupled to the lifting cylinder (500).

In addition, it is preferable that a support bracket (B) is installed at the lower part of the first to fourth cylinders 100 to 400 to support the inclined lower part of the first to fourth cylinders.

The inclination angle of the first cylinder 100 and the second cylinder 200 is not particularly limited, and is taken into consideration the load of the lifting cylinder 500 and the load strength of the first cylinder 100 and the second cylinder 200. Just set it appropriately.

The wheel 600 is installed at the end of the rod of the lifting cylinder 500 and descends toward the ground when the rod is pulled out.

The beam extractor moving device of the present invention configured as described above is used when moving the beam extractor (1) to the working position for beam extraction or moving the beam extractor (1) to the next working position after completing beam extraction. As shown in 4a, when the rods of the first cylinder 100 to the fourth cylinder 400 are pulled out simultaneously, the lifting cylinders 500 rise to the same height and move the same distance in the left and right directions, and the beam extractor ( 1) moves to the outside of the base 10.

In this state, when the rod of the lifting cylinder 500 is pulled out, the wheel 600 installed at the end of the rod lowers and touches the ground, as shown in FIG. 4B. And in this state, when the rod of the lifting cylinder 500 is further pulled out, the beam extractor 1 rises from the ground along the lifting cylinder 500, as shown in FIG. 4C.

At this time, the operator raises the beam extractor 1 to a height where the base 10 of the beam extractor 1 does not interfere with the top of the H beam H protruding from the ground.

In this way, when the beam extractor 1 rises from the ground, it is possible to move the beam extractor 1 to a desired position by pushing or pulling it forward or backward without mobilizing heavy equipment.

As shown in FIG. 5, there is a drive unit 650 at the rod end of the pair of lifting cylinders 500 facing each other so that the beam extractor 1 can move by magnetic force, which provides rotational force to the corresponding wheel 600. Can be installed.
