Description

Multi-function rotary demolition breaker {Multi-function rotary demolition breaker}

The present invention relates to a multi-function rotary demolition breaker, and more specifically, to a hydraulic breaker that is combined with a connecting rod provided at the tip of the arm of an excavator to strike and crush rocks or concrete blocks, and is used to dismantle (demolish) various buildings, etc. ) By selecting and installing any of the jaws for shears, crushers, or pulverizers required for the work, dismantling (demolition) of buildings, etc. can be performed smoothly using a single hydraulic breaker, as well as hydraulic breaker. A multi-function rotary demolition invented by providing a rotating means between the upper part of the breaker housing and the excavator coupling member so that objects at any angle can be smoothly dismantled (demolished) at the relevant location without a large change in direction or movement of the excavator. It's about breakers.

In general, an excavator is a construction machine that mainly digs and excavates soil, and is a construction equipment that performs various tasks depending on the type of work device attached to the tip of the excavator arm.

In addition, the crusher is a device that crushes bulky stones, concrete, asphalt, etc. so that they can be recycled as building materials, and at the same time cuts the rebar and steel materials contained in the concrete. It includes a reciprocating transfer cylinder and It is a construction work equipment consisting of a tooth and a cutting blade that are interlocked to crush raw stones or concrete structures, combined at the top and bottom of the main body.

A breaker is a device that breaks rock, concrete, or asphalt by repeatedly applying downward impact force according to the action of hydraulic pressure, similar to the principle of striking a chisel with a hammer. It is linked with a reciprocating transfer cylinder to break rock or asphalt. It is a construction work equipment consisting of a rod that strikes a concrete structure, that is, a chisel (chisel), combined inside the main body.

However, most conventional breakers are designed to break rocks when working in areas with a lot of rocks, and are configured to be independently mounted on the excavator arm, so breaking is easy, but cutting rebar or crushing rocks during work is easy. There was the inconvenience of having to remove the installed breaker and replace it with a crasher, etc.

Accordingly, recently, complex work equipment in which the breaker and the crusher are formed as one piece (also called “multi-hydraulic breaker”) has been developed and released.

In this way, most conventional hydraulic breakers equipped with an integrated crusher have no rotation function at all, so they crush and cut the dismantled object using a specific attachment (breaker, crusher, pulverizer, shear, etc.) in a specific direction. When trying to crush and dismantle an object in a certain direction, there is the inconvenience of having to shred and dismantle the object while moving the excavator or rotating the boom direction in response to the direction of the object. There is a problem in that disassembly work takes a lot of time and money.

In addition, when various attachments are used to demolish an old building, a significant amount of concrete fine fragments and dust are generated, making it difficult for workers to see, or contaminating the workplace environment with fine dust.

To prevent this, another person sprays tap water or connects a water pipe to the excavator boom to moisten the building in the area where the work is being done. However, if a person sprays water directly, labor costs are incurred, and debris is generated when the building is demolished. It is exposed to an environment where it can cause injury, and when mounted on an excavator boom, there is a problem that it is difficult to accurately align the spray position with the work point.

In order to solve the above problem, the present inventor would like to propose a multi-function rotary demolition breaker.

This shows a side view of the encounter in an open and closed state.

In addition, Figure 8 shows a perspective view of a multi-function rotary demolition breaker to which another embodiment of the present invention is applied.

According to this, the multi-function rotary demolition breaker to which an embodiment of the present invention is applied, as shown in FIGS. 1 to 4, largely consists of a hydraulic breaker 10, a jaw 20, a hydraulic cylinder 30 for the jaw, and an excavator coupling member. It includes (100) and a rotation means (200).

In addition, the multi-function rotary demolition breaker may further include a housing 40, a cylinder upper assembly member 50, and a jaw assembly member 60.

In addition, the hydraulic breaker 10 includes a chisel 12 coupled to the hydraulic cylinder 11 for a reciprocating breaker.

At this time, the hydraulic cylinder 11 for the breaker is installed in the housing 40 of the hydraulic breaker 10.

The hydraulic breaker 10 is installed in a housing 40 to be described later so that only the chisel 12 is exposed to the outside, and the hydraulic cylinder 11 for the breaker is operated in response to the excavator operator's operation. The chisel 12, which is replaceably coupled to the lower end of the piston of the breaker hydraulic cylinder 11, reciprocates in response to the operation of the breaker hydraulic cylinder 11 and crushes rock or concrete structures by striking them. performs its function.

In addition, the jaw 20 corresponds to at least one of a jaw for a shear, a jaw for a crusher, or a jaw for a pulverizer each having a plurality of teeth 21 on the inside, and the upper end of the hydraulic breaker 10 The front middle portion, that is, the upper portion is detachably coupled to the jaw assembly member 60 installed on the front of the housing 40 with the hydraulic breaker 10 installed therein, through an assembly pin 61. .

This jaw 20 is rotated based on the assembly pin 61 of the jaw assembly member 60 in response to the direction of the operating pressure of the hydraulic cylinder 30 for jaws, which will be described later, and moves like scissors in FIGS. 1 and 7. It performs the function of cutting the reinforcing bars and steel materials existing between the front of the housing 40 and the inner surface provided with the teeth 21 by repeating the operation of being closed together and then opening as shown in FIGS. 1, 5, and 6. do.

In addition, the hydraulic cylinder 30 for the jaw is located on the front upper part of the hydraulic breaker 10, that is, between the front upper part of the housing 40 in which the hydraulic breaker 10 is installed and the middle part of the jaw 20. It has an installed form.

In the hydraulic cylinder 30 for such a jaw, a cylinder rod whose end is hinged to the middle part of the jaw 20 reciprocates from the inside to the outside of the body in response to the excavator operator's operation, and moves in and out of the jaw 20. It performs the function of providing rotational force and cutting pressure.

At this time, the installed number of the jaws 20 and the hydraulic cylinders 30 for the jaws may vary depending on the type of jaw to be applied or installed in the multi-function rotary demolition breaker of the present invention.

For example, in the case of a shared jaw or crusher jaw configured with two jaws 20 forming a set, two jaw hydraulic cylinders 30 are also installed, and a pulverizer consisting of one jaw. In the case of an encounter, only one hydraulic cylinder 30 for the encounter may be installed.

Therefore, workers who use excavators to dismantle (demolish) various buildings, etc., select one of the above-mentioned jaws for sharing, jaws for crushers, or jaws for pulverizers and replace them according to the site conditions during the dismantling work. In addition, the number of hydraulic cylinders 30 for the encounter may be determined and installed according to the type and number of the encounter.

Meanwhile, as shown in Figures 5 to 7, which are shown as other embodiments of the present invention, including Figure 1, the upper front part of the housing 40 is provided with an assembly pin 51 at the upper end of the hydraulic cylinder 30 for encountering. It includes further installing a cylinder upper assembly member 50 to be detachably coupled through.

At this time, the cylinder upper assembly member 50 is a pair of wings using an iron plate having a predetermined area and thickness and having assembly pin passing holes (not shown for drawing protection) drilled on both sides of a fixing plate 52 having a predetermined area. (53) has a form that is integrally bent and formed through a cutting and bending process.

However, when manufacturing the cylinder upper assembly member 50 as described above, in the bending process of integrally bending and forming a pair of wings 53 on both sides of the fixing plate 52 using an iron plate having a predetermined thickness and area, There is a risk that the area between the fixing plate 52 and the pair of wings 53 and the lower end of the fixing plate 52 may be weakened or damaged due to bending stress.

Accordingly, separate assembly member reinforcement plates 54 are further formed on the outer surfaces of both wings 53 integrally bent on both sides of the fixing plate 52 of the cylinder upper assembly member 50 and on the front of the lower end of the fixing plate. It is desirable to prevent damage between the fixing plate 52 and the pair of wings 53 and the lower end of the fixing plate 52 due to bending stress.

In addition, a jaw assembly member 60 including a pair of hinge pieces for coupling assembly pins is further installed on the front of the housing 40 below the cylinder upper assembly member 50.

In this jaw assembly member 60, the upper end of the jaw 20 is removable between the hinge pieces (reference symbols omitted) for coupling the assembly pins of the jaw assembly member 60 through the assembly pin 61. It performs a function that allows it to be combined.

At this time, the jaw assembly member 60 is manufactured separately from the cylinder upper assembly member 50 as described above and is detachably installed on the front of the housing 40 from the lower part of the cylinder upper assembly member 50. It is not limited to this, and may include one in which the jaw assembly member 60 and the cylinder upper assembly member 50 are integrally formed.

That is, when manufacturing the cylinder upper assembly member 50, the jaw assembly member 60 may be formed integrally at the bottom of the fixing plate 52 of the cylinder upper assembly member 50. In this way, the two assembly members When molded as one piece, the manufacturing cost of the assembly members can be reduced and assembly can be simplified.

In addition, it may further include a pair of lower cylinder assembly plates 70 having assembly pin passing holes (reference symbols omitted) drilled on both upper sides of the jaw 20.

In this way, when a pair of cylinder lower assembly plates 70 are further installed on both upper sides of the jaw 20, the lower end of the hydraulic cylinder 30 for the jaw is not directly coupled to the jaw 20, and the With the pair of cylinder lower assembly plates 70 positioned, they can be detachably coupled through the assembly pins 71.

In addition, a shear strength reinforcement plate 72 may be further installed on the outer surface of the cylinder lower assembly plate 70.

In this way, if the shear strength reinforcement plate 72 is further installed on the outer surface of the cylinder lower assembly plate 70, the shear strength of the cylinder lower assembly plate 70 formed of a steel plate with a certain thickness will be greatly increased. Therefore, the hydraulic cylinder 30 for a long period of time rotates the jaw 20 and the cylinder lower assembly plate 70 is driven by a strong shear force applied when cutting reinforcing bars and iron materials through the jaw 20. It can prevent itself from being damaged or destroyed as much as possible.

In addition, in the present invention, a cutter 81 having a substantially blade shape and a crushing plate 82 having a triangular plate shape are further installed at a predetermined distance in the upper and lower directions from the front lower part of the housing 40. Includes.

When the jaw 20 is strongly rotated in the front direction of the housing 40 and the retracting operation is performed, the reinforcing bars and steel materials are formed on the teeth 21 of the jaw 20 and the cutter 81. ), and rock and concrete are smoothly crushed between the teeth 21 of the jaw 20 and the crushing plate 82, making it easier to dismantle (remove) the object using the jaw 20. It can be cut and shredded effectively.

In addition, the present invention may include installing a wear-resistant reinforcement plate 83 on the front of the housing 40 where the cutter 81 and the crushing plate 82 are installed.

In this way, with the wear-resistant reinforcement plate 83 further installed on the front of the housing 40, the jaw 20 is strongly retracted in the front direction of the housing 40 through the jaw hydraulic cylinder 30. When the unfolding operation is repeated, a part of the disassembly (removal) object that is located between the inner surface of the jaw 20 and the front of the housing 40 and is cut and damaged does not directly contact the front of the housing 40. In a state of contact between the inner surface of the jaw 20 and the outer surface of the wear-resistant reinforcement plate 83, the teeth 21 including the inner surface of the jaw 20, the cutter 81, and the crushing plate (82) It is cut or broken between.

Therefore, not only can the wear resistance of the front part of the housing 40 be greatly increased, but it is also possible to completely prevent a portion of the front part of the housing 40 from being worn by disassembly objects.

In addition, the present invention may include installing a plurality of wear-resistant reinforcement members 84 at predetermined intervals between both sides of the upper surface of the wear-resistant reinforcement plate 83 and both sides of the housing 40.

In this way, when a plurality of wear-resistant reinforcement members 84 are further installed between both sides of the upper surface of the wear-resistant reinforcement plate 83 and both sides of the housing 40, the jaw 20 is moved through the hydraulic cylinder 30 for the jaw. When the operation of strongly squeezing and unfolding is repeated in the front direction of the housing 40, in addition to the wear resistance improvement function of the wear resistance reinforcement plate 83, which prevents wear of the front part of the housing 40, the wear resistance reinforcement plate ( 83) performs the function of significantly improving the wear resistance on both sides of the housing 40.

Therefore, disassembly (removal) is located between the inner surface of the jaw 20 and the front of the housing 40 and is cut and damaged between the jaw 20, the cutter 81, and the crushing plate 82. It is possible to more completely prevent the front part of the housing 40 as well as both sides of the housing 40 from being worn, deformed, or damaged by objects.

In addition, the present invention may further include a cutting object separation prevention member 90 formed with a cutting object catching groove 91 formed on the front lower end of the housing 40.

The cutting object separation prevention member 90 is connected to the front part of the housing 40 and the jaw 20 in the process of cutting the reinforcing bar or various steel materials through the retracting operation of the jaw 20. Some objects that escape through the gap between the inner surfaces are caught in the cutting object catching groove 91 of the cutting object separation prevention member 90, so that a larger amount of objects can be cut in a single cutting process.
