Description

　Concrete file cutting equipment using cooling unit integrated wire saw}

The present invention relates to a concrete pile cutting equipment, and more particularly, cutting a concrete pile including the head by adopting a body provided with a wire saw connecting the concrete pile and a hydraulically driven flywheel and a hydraulic cylinder horizontally moving the body And, it relates to a concrete pile cutting equipment using a cooling device-integrated wire saw, including a cooling device for supplying cooling water to the contact portion of the wire saw and the flywheel.

In general, in large-scale construction or civil works, a concrete pile foundation is constructed to support the structure after the initial excavation. When the concrete pile foundation is connected to the structure, the work of arranging the upper part, that is, the head, of the concrete pile is performed. In other words, in order to place the foundation reinforcement and concrete, the foundation floor must be horizontal, so head arrangement is performed for this.

Concrete pile construction is largely divided into pile drilling, excavation and pile reclamation, and head trimming.In the case of pile head trimming, if cracks occur in the process of crushing the concrete pile, the pile strength of the part connected to the foundation is remarkable. Due to the decrease, it was difficult to secure sufficient bearing capacity to support the structure, and it was difficult to maintain the uniformity of the quality of concrete piles as it was not possible to adequately respond to invisible cracks that were difficult to grasp from the outside.

On the other hand, among the conventional methods of arranging the head of a concrete pile, the method using a crusher is to crush to the point (cutting line) to be cut with a cutter, but in this case, the work productivity is increased due to the amount of work to be performed by the hall stonemason. Since a lot of deterioration and cumbersome work occurs, the concrete is crushed close to the cutting line. This is because the steel wire of the pile is pulled forcibly during the process of crushing the concrete with a crusher, causing cracks inside and outside the bottom, which is a great influence on the quality of It means that there is an effect, and this crack is a major cause of delay in construction and increase in construction cost because repair and reinforcement work is required after the head trimming work.

Next, the one-cutting method has the advantage that the cutting surface of the head is cut cleanly, but similarly, there is a problem in that the quality of the pile, the safety decrease, and the productivity decrease occur.

The cutting operation using a grinder using electricity poses a risk of electric shock, and the general laborer uses a cutter and a hydraulic cutter to cut the steel wire, causing the cut steel wire to bounce during the cutting process and cause injury to the worker. Therefore, since the work is being performed in a soft work environment where safety is not secured, it is the time when a technology capable of performing head tidying work within a safe work environment is required.

In the'Pile Head Cutting Device' of Patent Document 1 below, a circular rail 20 that is wrapped in a ring shape on the outer diameter of the pile 5 and fixed by a clamping force, and a circular rail 20 positioned outside the circular rail 20 and supported by rolling contact A cutter moving carriage 30 that moves along the circumference of the pile 5 in the state; A cutter support arm 40 that is hingedly connected to one place of the cutter moving carriage 30 to be rotated; And an electric cutter 50 positioned at the end of the cutter support arm 40 and fixedly mounted, and the cutter support arm 40 is positioned in the circumferential direction by a predetermined pitch while the electric cutter 50 is operated. It is configured to cut the pile 5 by moving the rotary cutter 50 in the radial direction at the same time as moving; The circular rail 20 includes a pair of hinge plates 21 and 21 having a hinge shaft 22; An upper ring 23 and a lower ring 24 which are divided into semicircles and have one end connected to the pair of hinge plates 21 and 21 to be opened and closed; A spacer 25 connected to the upper and lower rings 23 and 24 and arranged at regular intervals in the circumferential direction to form a predetermined distance between the pile 5 and the upper and lower rings 23 and 24; And a clamp means 26 installed on the other side of the upper ring 23 and the lower ring 24 to contract the diameters of the upper and lower rings 23 and 24 to fix the circular rail 20 Although this is described, since a circular rail made of a round bar or a circular steel pipe in a circular ring shape is used, the cutter moving carriage is stably supported and the cutting operation is made safely.

However, there is a problem that the cutting operation is performed through the light-weight electric cutter 50 using electricity, so that the operation is possible only in an area where electricity supply is smooth, and the area cut through the electric cutter 50 due to the structure is outside the concrete. There is a problem that the head of the concrete pile cannot be completely cut by only reinforcing bars. In addition, as a structure in which the pile head cutting device is detached and attached to the outer surface of the concrete pile, there is a problem that several workers are required because the pile head cutting device must be installed at the cutting position while holding the pile head cutting device.

Therefore, for the wire saw 150 to be cut in contact with the outer surface or the outer circumferential surface of the concrete pile, the wire saw 150 additionally generates a force to press the cut surface, thereby enhancing the cutting force of the wire saw 150 It is done.

The flywheel 140 will be described. The circular (specifically, disk-shaped) flywheel 140 is provided on one side of the main body 120, and the flywheel 140 includes a hydraulic driving unit 141 to drive a hydraulic motor (not shown). do. The hydraulic drive unit 141 is connected through the body 120 and the third hydraulic line 123 and is configured to rotate the flywheel 140 by driving the hydraulic motor by hydraulic pressure provided from the body 120.

The flywheel 140 may rotate in one direction or may reciprocate in both directions within a predetermined range while limiting the rotation angle of the flywheel 140 to a predetermined range.

When the flywheel 140 rotates, an annular wire saw 150 connecting the flywheel 140 and the concrete pile is engaged with the flywheel 140 to cut the concrete pile during rotation. Of course, in this process, the hydraulic cylinder 130 continuously moves the body 120 in the opposite direction to the concrete pile.

The flywheel 140 is provided vertically on one side of the body 120 as shown. The wire saw 150 fastened to the circular flywheel 140 is fastened up and down of the flywheel 140 disposed vertically with respect to the body 120 to rotate, and the wire saw 150 is the flywheel 140 and In the front and rear regions to be fastened or engaged, the annular wire saw 150 is arranged vertically in parallel.

The wire saw 150 will be described. The wire saw 150 is a form in which a ring-type diamond saw is continuously spaced apart from and coupled to a wire, and a method of arranging a diamond saw on the wire or forming angle may be variously provided.

The wire saw 150 is generally composed of a flexible wire in a closed shape such as an annular or elliptical shape, and one side of the wire saw 150 surrounds and contacts a part of the outer surface of the concrete pile to be cut, and the other side of the flywheel 140 It is connected while wrapping a part. In other words, it is a closed wire that is pulled tightly while surrounding the concrete pile and the flywheel 140 to be cut as both axes.

In the front and rear area of the portion where the wire saw 150 is fastened or engaged while surrounding the flywheel 140, both sides of the annular wire saw 150 are arranged vertically in parallel, but the cut surface of the concrete pile to be cut is horizontal. , In the concrete pile part wrapped by the wire saw 150, both sides of the annular wire saw 150 should be arranged horizontally in parallel, which is provided with a plurality of wire saws 150 passing through the flywheel 140.

That is, in the portion where the wire saw 150 wraps around the flywheel 140 and fastens or engages, the flywheel 140 rotates on a vertical surface, so the wire saw 150 also moves up and down. In the front and rear areas, the wire saw 150 must be moved horizontally in a parallel state to cut the concrete pile horizontally.

Accordingly, the wire saw 150 that enters the lower side of the flywheel 140 and comes out to the upper side is interlocked with the plurality of switching wheels 160 to pass through the last lower switching wheel 160, while entering the lower side of the flywheel 140 It is similar to the height of the wire saw 150 is eventually arranged in parallel in a horizontal state.

In addition, all three switching wheels 160 may be provided on the body 120 or may be provided on the frame 110.

The number or position of the switching wheel 160 is not particularly limited, and the position may be variably adjusted by the switching wheel mounting bracket 161.

In particular, the conversion wheel 162 provided at the lowermost side of the three conversion wheels 160, which is located in the front and close to the concrete pile to be cut, rotates a predetermined angle from the front to the left and right by the conversion wheel installation bracket 161 It is equipped to be able to do.

During the operation, the wire saw 150 that came into the lower side of the flywheel 140 facing the front passes through the last conversion wheel 162 and faces completely forward, thereby extending the wire saw 150 surrounding the concrete pile. Both sides of the should be kept parallel.

Although not shown, the size (or roughly the diameter) of the concrete pile remaining while being cut during the concrete pile cutting operation continues to decrease.

Therefore, in the starting stage of the work, the conversion wheel 162 is completely directed forward by the conversion wheel installation bracket 161, but as the cutting operation proceeds, the conversion wheel installation bracket 161 rotates slightly inside the front reference, and similarly, the conversion wheel By allowing the 162 to rotate little by little to a predetermined angle, the straight portions of both sides of the wire saw 150 that extend left and right surrounding the concrete pile, that is, the side entering the flywheel 140 and the side exiting the conversion wheel 162 By keeping them continuously parallel, it is possible to optimize the cutting operation without loss of cutting force.
