Description

H-Beam extract machine with wedge type clamp

The present invention relates to an extractor for drawing out H-beams buried underground, and more particularly, to an H-beam extractor capable of strongly clamping and extracting beams using a wedge-shaped clamp. In order to block the inflow of soil, water, etc., the construction of the screen is carried out. In this case, the H-beam is used for landfill. After the construction of the curtain and the completion of the construction or civil works, the beams that have no effect on the structure must be withdrawn and reused. However, since no mechanical device has been developed for this purpose, the beams cannot be drawn out, so a large amount of beams are buried underground, causing environmental pollution (ground water or soil) or waste of resources.

As a conventional machine, a vibrator type machine may be used for beam drawing, but very small amount (less than 5% of statistics) is drawn out due to the lack of drawing power which can draw the beam due to the characteristics of the machine. to be.

An object of the present invention is to provide an extractor capable of effectively extracting a buried H-beam with strong clamping force and withdrawal power. For this purpose, the extractor of the present invention has a wedge-shaped clamp that repeatedly performs beam clamping / unclamping by the lifting and lowering operation of the body.

The H-beam extractor according to the present invention includes: a base fixed to the ground; A lifting cylinder fixed to the base; A body which is repeatedly moved upward and downward by the operation of the lifting cylinder; It is installed in the body and consists of a wedge-shaped clamp that clamps the beam when the body is raised and releases the beam when the body is lowered again. The clamp preferably comprises a flow wedge which flows in contact with an inclined surface formed in the body. According to the extractor of the present invention, the clamping and withdrawing of the clamp is made with the raising of the body, and the beam with the lowering of the body. Unclamping takes place. And the rise and fall of the body is repeated until the beam is completely pulled out. Features of the present invention and the resulting effects thereof will become more apparent through the embodiment description described below with reference to the drawings. In other words, the H-beam extractor according to the present invention is denoted by reference numeral 10. The dispenser 10 includes a base 12 stationary on the ground, two lifting cylinders 14 upright on the base 12, and an upper side of the base 12, both sides of which are disposed on each lifting cylinder 14. The base 12 is a stationary object seated on the ground, and the lifting cylinder 14 is a hydraulic cylinder that repeats the rising and falling. The beam H protruding from the ground passes through each center of the base 12 and the body 16. Here, reference numeral 18 denotes a jack cylinder fixed to the base 12. Referring to FIG. 2, each of the elevating cylinders 14 is bolted onto the base 12, and the body 16 is each elevating cylinder. It is bolted to 14. In addition, a clamp 18 is installed at the inner center of the body 16. The clamp 18 has a symmetrical structure with respect to the horizontal side h of the beam H passing through the center of the body 16. It consists of two fixing wedges 20 and two floating wedges 22 of symmetrical structure disposed between each fixing wedge 20 and the horizontal side h of the beam H. The fixing wedge 20 has one side. The inclined surface is formed to the lower side, is fixed to the body 16 is moved with the body 16. However, the fixing wedge 20 may be formed integrally with the body 16. On the other hand, the flow wedge 22 is formed in one side of the inclination narrowing to the lower side, the inclined contact with the fixed wedge 20 is to be able to flow in accordance with the vertical movement of the fixed wedge 20. On the other side of the flow wedge 22, a toothed projection 23 is formed to increase the contact frictional force with the transverse side h of the beam H at the time of beam extraction. Beam H protruding from the ground The silver passes through the base 12 and the clamp 18 in the center of the body 16. Referring to FIG. 3, the transverse side h of the beam H is located between two flow wedges 22, and both longitudinal sides of the beam H are located at the side of the flow wedge 22. Referring to, the jack cylinder 24 is fixedly installed on the base 12 to help the body 16 to rise. A first wedge 28a having an inclination is fixed to an end of the reciprocating shaft 26 of the jack cylinder 24, and a second wedge 28b that is in inclined contact with the first wedge 28a at a lower portion of the body 16. The extractor 10 of the present invention configured as described above has a clamp (a) by repeated lifting and lowering operations of the body 16 made by the operation of the lifting cylinder 14 and lifting and lowering of the body 16. Through the beam clamping / unclamping operation of 18), the beam H can be drawn out. 5 and 6, a process of drawing the beam H is described. Referring to FIG. 5, when the body 16 is raised: the floating wedge 22 in oblique contact with the fixed wedge 20. The pressure flows at the push pressure of the fixing wedge 20 and clamps by pressing the horizontal side h of the beam H. As the body 16 continues to rise in this state, the beam H is drawn out of the ground by a certain length, specifically, the stroke length of the lifting cylinder 14. At this time, the lifting cylinder 14 lacks a force. If the rise of the body 16 (withdrawal of the beam) is not smooth to operate the jack cylinder 24. When the jack cylinder 24 is operated, the first wedge 28a is advanced, and the second wedge 28b which is in inclined contact with the first wedge 28a is raised to allow the body 16 to rise (see FIG. 7). Referring to FIG. 6, when the body 16 descends: as the fixed wedge 20 descends, there is a play between the fixed wedge 20 and the flow wedge 22, thereby causing the flow of the wedge 22. Beam H clamping is released. That is, the beam is unclamped. At the same time, the flow wedge 22 descends to its own weight and prepares for the next clamping. When the body 16 rises again, the beam H clamping of the flow wedge 22 is made in the same operation as in FIG. A certain length is withdrawn. The drawing operation according to the rise and fall of the body 16 proceeds repeatedly until the beam H is completely drawn out.

The drawer of the present invention takes out the beam H by the lifting and lowering operation of the body 16 and the clamping / unclamping of the flow wedge 22 by this operation. Therefore, there is an effect that can effectively withdraw the H-beam with a strong clamping force and the output power. It is also economical due to its complex structure and operation, and it is less likely to cause disturbances. It is a device provided especially for H-beam extraction, which can largely prevent soil and water pollution, save national resources, At least, it will not only help the cost reduction of construction or civil engineering companies, but will also be able to anticipate the effects of job creation by running a withdrawal business.
