Description

Excavator mounted on fork lane {AN EXCAVATOR HEAD FOR USEING BACK HOE}

The present invention relates to a forklift-mounted drilling rig, the arm connecting rod of the forklane is formed on the upper side of the frame, so that the angle is adjusted two to three times as compared to the conventional rig, and in particular, the hydraulic pressure for adjusting the left and right of the frame By installing a cylinder to move the frame to the left and right has a feature that can greatly improve the workability.

And while using a frame having a small height compared to the conventional excavation device by using a two-stage hydraulic cylinder and a double hydraulic cylinder can be formed deeper depth of the excavation groove, the arm connecting arm of the fork crane is formed on the upper side of the frame In this case, the piston rod and the arm of the fork crane, the frame, the hydraulic cylinder, etc. are given little or no interference, so that a wide range of operations are possible.

In general, as an initial stage of foundation work for building construction or civil engineering, a process of removing rock or rock buried in the ground or basement is first performed. For the removal of rock or rock for this purpose, a method of crushing and removing the rock with a hydraulic vibration crusher mounted on the fork-lane (A), a method of blasting the rock or rock using explosives (B), a vibration crusher To form a small hole in the surface of the rock, and to squeeze it into the hole by using a separating plate that opens to the left and right by the advance of the hydraulic wedge (C), and to remove it by using the cylindrical cutter rotary excavator as in the present invention. After the excavation groove of 150mm diameter or more is formed in the rock or rock, the rock in the above excavation groove is taken out as the upper cylinder cutter is lifted up. There is a way to get rid of lumps.

However, the methods of (a) and (b) have caused a lot of complaints due to the vibration, noise, and dust, which cause pollution, harm the human body, and simultaneously crack the buildings around the workplace. As a matter of fact, it is becoming increasingly difficult to use in Korea, including developed countries.

In the above (c) method, a hole is formed in a rock or a rock by using a small diameter vibration crusher, and a crushing device consisting of a separating plate and a wedge is inserted into the hole, and the upper cylinder is advanced by a hydraulic cylinder. Advancement of the separation plate to the left and right by rock advances the rock, which is relatively used to remove the rock or used in small workplaces, and because it does not solve the vibration, dust, noise and cracks in the building around the workplace It is not received and urgently required improvement measures. Accordingly, as the present invention, a cylindrical cutter rotary excavator having excellent workability and excellent work efficiency with little noise and little vibration and dust is generated and used. Very quiet and fresh compared to one conventional method And emerged a disadvantage, while following the advantage of dust or vibration rarely occurs. That is, Korean Utility Model Registration No. 104282 (excavator; hereinafter referred to as "Line Registration Invention") is provided with excavation means in which a rotary tube with a cutter attached to a lower end thereof is rotated by a hydraulic motor, and the rotary tube is provided. The hydraulic cylinder for vertically moving the housing is fixed with the hydraulic cylinder extending upward through the upper surface of the frame, and the connecting plate for forging the arm and the piston rod is welded to the back of the frame where these devices are assembled. The arm piston piston rod of the fork-lane is connected to it through a fastening pin. In the above-described digging device of the invention, the rotating tube rotated by the hydraulic motor can move up and down to form a hole in the surface of the rock. And the angle of the frame can be modified only in the front-rear direction with respect to the front of the fork-lane by the operation of the arm wave piston rod of the fork-lane. have. However, the pre-registration of the invention is that the frame does not tilt in the left and right directions, so the excavation groove cannot be formed on the rock slope of the side of the fork-lane while the fork-lane stops in place. There are many big uneconomical disadvantages. And as described above, because the frame does not tilt toward the inclined surface of the rock, because the frame and the rotating tube can not be excavated at right angles to the inclined surface, the excavation is almost difficult, and the cutter at the bottom of the rotating tube may be damaged. There is a disadvantage in that the excessive force is generated on the arm and the piston rod of the fork-lane, and the structure of the hydraulic cylinder extended above the upper surface of the frame increases the height of the whole device, making it difficult to handle it. The connecting plate between the arm and the piston rod is fixed to the back of the frame by welding so that when the frame is pulled backward by pulling the piston rod of the fork crane, the arm of the fork crane and the piston rod interfere with the frame of the hydraulic cylinder. I can't get it at a big angle The Bureau is also working radius becomes smaller and is more uncomfortable to move the crane fork to work with the disadvantage poor workability.

The present invention is to overcome the above-mentioned conventional problems, an object of the present invention is that the frame of the excavating device mounted on the fork-lane can be moved at a larger angle before and after the conventional, in particular the frame can be inclined to the left and right Accordingly, it is to provide a fork-lane mounted excavation apparatus that can easily excavate the slope of the rock.

In addition, the present invention, while using a frame having a small height compared to the conventional drilling device, by using a two-stage hydraulic cylinder or a double hydraulic cylinder can form a deeper depth of the excavation groove, the arm connection of the fork crane It is formed on the upper side, the piston rod and arm of the fork-lane at the time of operation does not interfere with the frame 30 and the hydraulic cylinder, etc. The present invention provides a fork-lane-mounted drilling rig that is provided to enable a wide range of operations. To achieve the above object, the present invention is fastened to the arm and the piston rod of the fork-lane, assembled inside the frame, and moved up and down by a hydraulic cylinder.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

First of all, the present invention provides a connection table 42 having holes 44 and 46 formed therein so that the arm 62 of the fork lane and the piston rod 60 can be fastened to the upper side of the frame 30 as described above. The connecting table 42 is welded and fixed vertically, and the support plate 40 is configured to be hinged with the shaft pin 34 between the frame 30 so that the frame 30 can be tilted left and right. And, the left and right angle of the frame is connected between the bottom surface of the support plate 40 and the brakit 48 fixed to the rear surface of the frame 30 so that the angle can be adjusted from side to side based on the support pack 40 An adjustment hydraulic cylinder 50 is provided, and as a means for moving the housing 14 up and down, a first hydraulic cylinder 20 and a second hydraulic cylinder 22 are provided, where the second hydraulic cylinder 22 is provided. Switch for controlling the start of operation and home position (28) is installed, in order to amplify the lever-type switch (28) up and down vertically fixed to the braces 16 fixed to the back of the housing 14, the pull 18 having a ring formed at the top is It is equipped with features. Of course, the first hydraulic cylinder 20 and the second hydraulic cylinder 22 may be replaced by a double hydraulic cylinder 23 composed of the first rod 23a and the second rod 23b which are drawn out and win-positioned in an antenna manner. To make it possible.

Hereinafter, the structure and operation of the present invention will be described with reference to the accompanying drawings.

As described above, the support plate 40 of the present invention has a support plate 40 on which the arm 62 of the fork lane and the symmetrical connecting rod 42 to which the piston rod 60 is fastened are vertically welded and fixed to the upper surface of the frame 30. The bracket 32 is fixed to the shaft pin 34 so that the frame 30 can be hinged. That is, in the present invention, the connecting rod 42 and the support plate 40 are hinged to the frame 30 on the upper portion of the frame 30 as shown in the drawing without fixing the connecting rod 42 to the back of the frame 30 by welding. It is formed to be able to move, which is important and plays an important role. The reason why the frame 30 is hinged relative to the support plate 40 before explaining the operation thereof is that between the rear surface of the frame 30 and the bracket 48 fixed to the bottom of the support plate 40 as shown in the drawing. It is due to the action of the hydraulic cylinder 50 for adjusting the left and right angle of the frame is fastened to.

On the other hand, when the arm and the piston rod of the fork lane is fastened to the connecting rod 42 as shown in the drawing, the connecting table 42 and the support plate 40 are fixed to the arm and the piston rod of the fork lane. In this state, when the piston rod 60 of the fork lane is pulled in, the frame 30 is lifted up to the left side, that is, the lower plate 38 is lifted toward the front of the fork lane, so that the frame 30 is inclined. The inclined rock face in the front can be excavated; on the contrary, if the piston rod 62 is further pulled out, the lower plate 38 is inclined toward the forkrain while the frame 30 is inclined toward the forkrain, and the rock is inclined from the front of the forkrain. Allow the surface to be excavated.

As described above, in the case of the basic excavation work as described above, the frame 30 should be able to be tilted freely to the front or rear of the fork lane (adjusting the angle), and the present invention supports the support plate 40 and the upper portion of the frame 30. A connecting rod 42 is provided, and the arm 62 and the piston rod 60 of the forklift fastened thereto have no interference with the frame 30 and no interference with the hydraulic cylinders 20, 22, 23. . However, in the conventional drilling rig, the hydraulic cylinder for operating the housing 14 is extended to the upper part of the frame 30, and the connecting rod 42 is fixedly welded to the rear surface of the frame 30. Likewise, there was a big problem that the frame 30 could not tilt the frame 30 back and forth at a large angle without being interfered with the arms and the piston rod of the fork-lane, and the present invention solved this problem.

Next, looking at Figure 7, it can be seen that the frame 30 is inclined to the right, the support plate 40 is coupled to the arm and the piston rod of the fork-lane while keeping the horizontal and only the frame 30 is tilted to the right It is lost. The reason is that when the hydraulic cylinder 50 for adjusting the left and right angle of the frame is operated and the piston escapes, the distance between the support plate 40 and the upper surface of the frame 30 is naturally increased, and at this time, the bottom surface of the support plate 40 and the frame Since the upper surface of the 30 is hinged by the shaft pin 34, the frame 30 is inevitably tilted. Meanwhile, when the piston of the hydraulic cylinder 50 is further pulled in, the frame 30 is inclined to the left side with reference to FIG.

As such, when the frame 30 is inclined to the left or the right side as shown in FIG. 7 while the fork crane is standing in place, the rock slope sloped to the left or right in front of the fork crane without moving the fork crane one by one. The inclined surface may be excavated as shown in FIG. 7, and as shown in FIG. 7, the lower plate 38 of the frame 30 is substantially parallel to the inclined surface of the rock to allow the rotary tube 10 to be perpendicular to the inclined surface. Most preferably, the cutter 11 and the rotary tube 10 do not overdo it, and the frame 30 may be safely mounted on the inclined surface. However, in the conventional excavation device, the frame 30 is not tilted left and right as in the present invention, and has no choice but to perform irrational, inconvenient and dangerous excavation work.

Next, basic usage tips of the entire apparatus will be described with means for moving the housing 14 of the present invention up and down.

The state of FIG. 2 is a standby state in which excavation work is performed on the surface of the rock, which is the same as that of FIG. Then, when the hydraulic motor 15 is operated, the rotary tube 10 in which the cutter 11 is fixed to the lower end rotates, and an industrial diamond tip is fixed to the lower end of the upper cutter 11. When the rotary tube 10 rotates and the hydraulic system of the control box (not shown) is operated, the piston of the first hydraulic cylinder 20 starts to descend gradually and starts to form an excavation groove on the surface of the rock as shown in FIG. 3. . On the other hand, referring to Figures 2, 3, and 4, the pull 18, which has a ring formed at the top thereof, is fixed vertically to the edge of the horizontal brace 16 fixed to the rear of the housing 14. It can be seen that the lever-type switch 28 is fixed to the inner side of the frame 30. The lever-type switch 28 is connected to the above-described control box to control the hydraulic line. Since this technique is a known level, detailed description is omitted. Subsequently, in the state of FIG. 2, the hook of the pull 18 is located above the lever-type switch 28, and as shown in FIG. 3, the piston of the first hydraulic cylinder 20 descends and the housing 14 naturally descends. Pull 18 is also lowered at this time, the ring of pull 18 is placed in the state just before pulling down the lever-type switch (28). On the other hand, the pull 18 is good to use a spring steel excellent in elasticity.

In the state of FIG. 3, since the shallow excavation groove is formed on the surface of the rock, the rotary tube 10 and the housing 14 must be further lowered to form the excavation groove to a depth of about tens of centimeters. The secondary hydraulic cylinder 22 should be lowered with the starting point just before the piston rod of () is almost exited, and the ring of the upper pulley 18 is immediately before the piston rod of the primary hydraulic cylinder 20 is almost lowered. Is in the position just before pulling down the lever-type switch 28, and the piston of the primary hydraulic cylinder 20 is completely released from the cylinder, and the housing 14 is further lowered to pull the lever-type switch 28. The ring of (18) is pulled down. As a result, the operation of the primary hydraulic cylinder 20 is stopped and at the same time, the operation of the secondary hydraulic cylinder 22 starts, and as the piston rod of the secondary hydraulic cylinder 22 descends, the housing 14 descends and the rotary tube ( 10) If the piston rod of the secondary hydraulic cylinder 22 completely exits from the cylinder as shown in FIG. 4, the excavation groove of sufficient depth is formed in the rock. At this time, in the rotary tube 10 excavated into the rock as shown in Figure 4 there is a rock column in the form of a column, as shown in Figure 5 by operating the secondary hydraulic cylinder 22 to rotate the piston rod in place to rise Due to the vibration of (10) cracks are generated in the rock roots of the shape of the weft column, so as to be cut and rise with the rotary tube 10 while being embedded in the rising rotary tube 10. As shown in FIG. 5, when the secondary hydraulic cylinder 22 is raised to raise the housing 14, the lowered pull 18 is also raised while lifting the lever-type switch 28 upward. Thus, the operation of the secondary hydraulic cylinder 22 is stopped and at the same time the primary hydraulic cylinder 20 is operated to return the piston rod, and the housing 14 and the rotary tube 10 in the state of FIG. 2 as in the original state. When the original position is stopped, the hydraulic motor 15 is stopped so that the rotary tube 10 is stopped. Afterwards, tap lightly on the rotary tube with a hammer, etc. The rock-shaped rock pillars embedded in the rotary tube 10 exit out of the rotary tube 10 and a hole is formed in the surface of the rock. After moving the forklift to the side again excavation work.

On the other hand, if a suitable number of holes are formed in the rock as described above, the hydraulic jacks are inserted into the above holes, and the high pressure hydraulic pressure is applied to split the rock (half rock). When the excavation work is to be performed on the rock slope of the side of the fork-lane side, conventionally, the fork-lane is stopped in a state in which the fork-lane is moved and the upper inclined plane is faced, and then the lower plate of the frame 30 is perpendicular to the upper inclined plane. 38) and then the excavation work, which takes a lot of time, inconvenient, and considering the rock topography factors, there was a lot of problems, such as increased risk of safety accidents, as described above As described above, the left and right sides of the frame 30 are operated by operating the hydraulic cylinder 50 for adjusting the left and right angle of the frame. This problem is solved simply by allowing the angle to be adjusted arbitrarily.

Next, the application example as the vertical movement means of the housing is to use a double hydraulic cylinder 23 as shown in Figs. The double hydraulic cylinder 23 is a cylinder assembly in which the second rod 23b is inserted at the innermost side and the first rod 23a is installed at the outer circumference thereof so as to draw out and return in an antenna manner, which is commercially available. Therefore, detailed description of the structure is omitted. First, when the rotary tube 10 is rotated and the hydraulic pressure is applied to the double hydraulic cylinder 23 in the same manner as described above in the excavation standby state as shown in FIG. 8, the first rod 23a first seals as shown in FIG. 9. You will exit the launcher body. In this case, the lever-type switch 28 and the pull 18 have the same function as the above-described example.

As the first rod 23a is pulled out as above, the housing 14 descends and forms an excavation flaw on the surface of the rock as shown in FIG. 9, and the hook of the pull 18 pulls the lever-type switch 28. Upon lowering, the second rod 23b immediately exits from the first rod 23a to form a deep excavation groove in the rock as shown in FIG. Since the following procedure is the same as the above-described example will be omitted.

On the other hand, the lower plate 38 of the frame 30 of the present invention is formed with a semi-circular hole (39) and the edge of the semi-circular hole (39) serves to hold the rotating rotating tube 10 less shake. However, the frame lower plate of the conventional apparatus is fixed by welding while exiting the rear of the frame at a distance from the rotary tube 10, and thus does not act to reduce the shaking phenomenon of the rotary tube 10 as in the present invention and rotates. The durability of the tube 10 is reduced, and thus the durability of the cutter 11 is also reduced. The present invention solves this problem by forming the upper semicircular hole 39 in the lower plate 38.

As described above, the apparatus of the present invention is located in the upper portion of the frame is connected to the arm of the fork and the piston rod is connected, the angle of the frame is bent back and forth several times compared to the conventional device in the state that the fork crane is stopped The working radius is wider and the forklift is easy to handle, which is characterized by excellent workability. In addition, when the frame is connected to the arm and the piston rod of the fork crane and the support plate, the frame can be bent freely from side to side with the hinge pin as a starting point, so that when the excavation to the inclined rock on the side of the fork crane does not have to move every day, It is convenient to work, shortens working air and reduces the possibility of a safety accident. The hydraulic cylinder, which is a means for moving the housing up and down, can be installed inside the frame. It is not cumbersome when using the present invention by preventing exposure to the outside, and there is no interference between the arm and the piston rod of the fork crane, and it has excellent workability and excellent usability, and uses two parallel hydraulic cylinders or an antenna-type dual hydraulic cylinder. Reduce the height of the frame Kige As there are a number of useful effects, such as that to facilitate the drilling operation in a small space, especially it can achieve the downsizing as a whole a wide range of end uses.
