Description

Concrete pipe jointer {device for coustructing fume pipe}

The present invention relates to a concrete pipe jointer for embedding a concrete pipe (Hume pipe) for guiding the flow of fluid (water, sewage, etc.), more specifically, suspended by a backhoe (Backhoe) has been carried on a truck The present invention relates to a concrete pipe jointer that quickly and accurately performs the discharging, transporting and joining of a concrete pipe into a pipeline.

1 is a longitudinal sectional view showing a joint of a concrete pipe, in which a water-expandable rubber ring 3 is fitted to a spigot 1a of a concrete pipe 1 to be joined in sequence, and another concrete pipe 2 as a joint thereof is shown. Airtightness is maintained between the inner diameters of the sockets 2a by the rubber rings, and the watertightness at the joints of the concrete pipes 1 and 2 depends on the material, the shape and the joining method of the rubber rings 3. .

Looking at the construction method according to the provision of such concrete pipes as follows.

The backhoe, called a fork lane, is defined as a construction method only for the excavation of pipe lines, and the lifting of concrete pipes by hanging with wire ropes is carried out for transporting concrete pipes on the excavated pipe lines or for joining the concrete pipes. It is prescribed to be a truck crane.

Therefore, after excavating the conduit 4 by the backhoe, the truck crane hangs the concrete pipe on the ground with a wire rope and sequentially transports it on the conduit 4 as shown in FIG. 2.

After the concrete pipes (1) and (2) to be installed on the pipe line (4) are arranged in this way, the inner diameter of the spigot (1a) and the corresponding socket (2a) formed on one side of the concrete pipe is cleaned and then spigot At the same time, the water-expandable rubber ring 3 is inserted into the thing 1a, and a lubricant is uniformly applied to the inner diameter of the spigot 1a and the socket 2a.

Thereafter, the concrete pipe 1 in which the rubber ring 3 is fitted is matched with the corresponding concrete pipe 2 using the wire rope 5 joined to a truck crane (not shown) as shown in FIG. 3. At the same time, one end of the wire rope 5 on which the lever block 6 is installed is joined to the concrete pipe 2 to be constructed, and the other end to the concrete pipe 1 to be constructed, and then the lever installed on the wire rope 5. The rubber ring 3 fitted to the spigot 1a is pulled out of the socket 2a by repeatedly pulling the block 6 and pulling the concrete pipe 1 into which the rubber ring 3 is fitted. It is combined while keeping airtight inside diameter.

This work is mainly applied when the inner diameter of the concrete pipe (1) (2) is relatively small, the operator can not work inside the concrete pipe.

However, when the inside diameter of the concrete pipe (1) (2) is large, the operator can enter the interior of the concrete pipe, the wire rope is bonded to the concrete crane (1) with the rubber ring (3) fitted to the truck crane as shown in FIG. (5) one end of the wire rope (5) in which the lever block (6) is installed in a state in which the support block (7) is supported in the interior of the constructed concrete pipe at the same time as the corresponding concrete pipe (2) Is fixed to the support wood, and then the other end is fixed to the support wood 8 positioned transversely to the opening of the concrete pipe 1 to be constructed, and then the lever block 6 installed on the wire rope 5 is repeatedly bent and rubberized. By pulling the concrete pipe (1) fitted with the ring (3) toward the construction of the concrete pipe (2) side, the rubber ring (3) fitted to the spigot (1a) is coupled to maintain the airtight in the inner diameter of the socket (2a).

Figure 5 is a longitudinal sectional view showing another embodiment for coupling a concrete pipe in the prior art.

In this case, the diameter of the concrete pipe (1) (2) is applied when the diameter is about 1,500mm or more, and the lever block (6) is 2 because the larger force is required during the joining operation of the concrete pipe (1) (2). I used it.

However, such a conventional concrete pipe (1) (2) joining work, the contractor breaks the construction regulations in order to reduce the cost and completed all the construction work with only one backhoe caused the following problems.

First, the concrete pipe (1) suspended on the wire rope (5) during the joining operation of the concrete pipe is shaken severely forward, backward, left and right, so that the spigot (1a) of the concrete pipe (2) fitted with the rubber ring (3) corresponding to the concrete pipe ( Extreme care must be taken when approaching the socket 2a inside 2).

However, due to carelessness, the joints of concrete pipes, which are usually made of concrete pipes, are frequently hit and broken, so that the watertightness at the joints could not be maintained.

Second, the rubber ring having a larger outer diameter than the inner diameter of the socket 2a because the concrete pipe is joined to the backhoe which is only to excavate the pipe line 4 by the wire rope 5 and then the concrete pipe is pulled out to perform the joining operation. 3) cannot be completely inserted into the inside of the socket, and thus the soil filling operation is performed without maintaining sufficient airtightness between the inner diameters of the socket 2a, so that a watertight effect cannot be expected.

Third, when constructing by the above-mentioned method, if the concrete pipes are joined in a state where the centers of the concrete pipes 1 and 2 do not coincide with each other, the rubber ring 3 inserted in the spigot 1a will become a socket. Since it is damaged by (2a), the airtight at a junction cannot be expected.

Fourth, when the construction is the same as the prescribed construction method requires a large number of people in the construction, because the construction cost was high, as well as a long time due to the construction will cause a smooth traffic communication.

The present invention has been made to solve such a problem in the prior art, by miniaturizing and lightweighting the concrete pipe jointer to perform the construction work of the concrete pipe within a short period of time even in a narrow space such as alleys, concrete joints of the concrete pipe Its purpose is to prevent leakage from occurring.

At this time, the guide rods 31 are fixed to both sides of the elevating member 26 so that the fingers 28 can move more stably, and each of the fingers 28 has an insertion rod 32 fitted to the guide rods 31. ) Is fixed.

The first, second, third, and fourth cylinders 20, 25, 27, 29 are each independently or a plurality of cylinders by operation of the control unit 33 installed on one side of the elevating member 26. Is to operate at the same time, the hydraulic source of the cylinder is to use the hydraulic source of the backhoe 12.

This is possible by extending the hydraulic hose (not shown) of the backhoe 12 to the side of the boom 13 and joining the control part 33 of the present invention in a one-touch manner.

Referring to the operation of the present invention configured as described above is as follows.

First, in order to use the concrete pipe joint of the present invention, as shown in Fig. 7, the bucket 34 is mounted on the boom 13 of the backhoe 12 and at the same time, the locking lever 17 to the locking pin of the support means ( 18) you have to walk.

In this state, the rod of the pair of fourth cylinders 29 driving the finger 28 is pulled out as much as possible, and the fingers are opened to both sides as shown in FIG. 10A, and the X-axis slider 24 is moved to the left in the drawing as far as possible. It keeps being in a state.

In addition, the Y-axis slider 19 fitted in the frame 11 is located in the middle of the frame.

Referring to Figures 10a to 11c attached to the process of mutual bonding construction of the concrete pipe (1) was unloaded along the pipe line 4 using the concrete pipe joint of the present invention in this state as follows.

In order to join the concrete pipe on the pipeline 4, the concrete pipe 1 unloaded along the pipeline 4 should be gripped and positioned on the pipeline.

To this end, when the finger 28 of the adapter suspended on the boom 13 is opened to both sides as shown in FIG. 10A, when the boom 13 is lowered by the operation of the backhoe 12, the finger 28 is connected to the concrete pipe 1. Will wrap.

In this state, when the finger 28 operates the lever of the control unit 33 to surround the concrete pipe 1, the fourth cylinder 29 installed in each of the elevating members 26 simultaneously drives the fingers that are opened to both sides ( As shown in FIG. 10B, the concrete tube 1 is gripped by the inner side of the concrete tube 1. When the finger 28 is retracted inward by the driving of the fourth cylinder 29 as described above, the finger ( 28 is inserted into the guide rods 31 fixed to the elevating member 26, the insertion rod 32 is fixed to the finger more stably.

At this time, the pusher 30 installed close to one finger 28 moves the boom 13 before wrapping the concrete pipe 1 by the finger 28 so that the pusher 30 is located close to the socket portion of the concrete pipe. The position of the splicer must be adjusted.

In this way, after a pair of fingers are lifted inward to grip the concrete pipe 1, the concrete pipe can be moved to the pipe line 4 by operating the backhoe 12 to raise the boom 13. .

After grasping the concrete pipe 1 which was unloaded along the pipeline by the finger 28, the backhoe 12 is operated to raise the boom 13 and at the same time the concrete pipe 1 suspended on the boom is connected to the pipeline 4. By turning the direction of the boom so as to be located on the upper portion of the), when the concrete pipe (1) suspended on the finger 28 is located on the conduit (4), the boom 13 is lowered.

In this way, if the central axis of the concrete pipe (1) suspended from the finger 28 and the concrete pipe (2) mounted on the finger 28 in the state in which the boom 13 of the backhoe 12 is lowered, the X axis slider The third cylinder 27 installed between the 24 and the elevating member 26 is driven to adjust the height of the concrete pipe 1 as shown by the dashed-dotted line of FIG. 10B so that the horizontal center axes of the concrete pipes can coincide with each other. do.

At this time, it is understood that two third cylinders 27 can be driven simultaneously or individually according to the inclination of the concrete pipe 1 suspended on the finger 28 and the inclination of the concrete pipe being constructed.

If the central axis in the vertical direction is displaced while the horizontal center axes of the concrete pipes (1) and (2) coincide with the above operation, the X-axis guide rods 21 of the frame 11 and the Y-axis slider 19 By driving the first cylinder 20 installed in the concrete pipe 1 is finely adjusted in the Y-axis direction.

That is, the concrete pipe joint is suspended on the boom 13 of the backhoe 12, the position of the frame 11 is unchanged, while the rod of the first cylinder 20 is hinged to the Y-axis slider 19 and Y Since the Y-axis guide rod 22 of the shaft slider 19 is fitted to the frame, when the rod of the first cylinder 20 is moved, the finger 28 hanging on the concrete pipe 1 as shown in FIG. 10C is, of course, X Since the shaft slider 24 is finely moved along the Y axis, the axis slider 24 is able to coincide with the vertical center axis of the concrete pipe 1. Accordingly, the central axis and the fingers of the concrete pipe 2 constructed as shown in FIG. The central axis of the concrete pipe (1) hanging on 28) is completely coincident.

After the center axes of the concrete pipes (1) and (2) coincide with each other as described above, the connection of the concrete pipes (1) and (2) is wiped clean, and the rubber ring (3) is inserted into the spigot (1a), A lubricant is applied evenly to the inner diameter of the thing 1a and the socket 2a.

In this state, when the second cylinder 25 is driven, the X-axis slider 24 fitted to the X-axis guide rod 21 is moved to the right in the drawing. At this time, the pusher 30 is attached to the elevating member 26 on one side. Is fixed so that the pusher 30 pushes the concrete pipe 1 suspended on the finger 28 to the coupling portion of the concrete pipe, so that the coupling work of the concrete pipe 1 is completed as shown in FIG. 11C.

After completion of the joining work of the concrete pipe (1) (2) by the operation as described above, the soil filling work to the bottom of the concrete pipe (1) after the joining work is completed, the fourth cylinder 29 and the second cylinder (25) ) Are sequentially re-driven to move inward to each other to reduce the finger 28 holding the concrete pipe 1 and the X-axis slider 24 moved in the insertion direction of the concrete pipe 1 to the initial state.

After the second and fourth cylinders 25 and 29 are re-driven, the gripping state of the concrete pipe 1 is released and the pusher 30 is reduced to an initial state. The concrete pipe joint located in the inside of 4) is vertically raised and at the same time by turning the boom 13, it becomes possible to join the next concrete pipe.

As described above, the process of joining the concrete pipe 1 adjacent to the pipe line 4 by the finger 28 and bonding the concrete pipe 2 to the concrete pipe 2 constructed on the pipe line has been described. After the operation is completed, by operating the backhoe 12 to raise the boom 13 and at the same time turning it to be able to continuously join the concrete pipe by the operation as described above.

As described above, the present invention has the following advantages over the prior art.

First, since the structure is simple and small and lightweight, it is possible to apply usefully when replacing the sewage pipe in a limited space such as an alley using a backhoe.

Second, the concrete pipe (1) suspended on the finger 28 is not shaken during the joining operation of the concrete pipe, so that the spigot (1a) of the concrete pipe (1) in which the rubber ring (3) is fitted to the corresponding concrete pipe (2) When approaching the inside of the socket (2a) it is prevented in advance to prevent the breakage of the joint due to inadvertent collision.

Third, the pusher 30 fixed to the X-axis slider 24 pushes the concrete pipe 1 so that the concrete pipes 1 and 2 are joined to each other, so that the spigot 1a into which the rubber ring 3 is inserted is socketed. The inside of (2a) can be completely pushed in, and thus perfect airtight at the joint of the concrete pipe can be maintained.

Fourth, since the center axes of the concrete pipes (1) and (2) coincide with the horizontal movement of the X and Y axis sliders (19, 24), the rubber ring (3) wrapped on the outer circumferential surface of the spigot (1a) is damaged. This will prevent the phenomenon.

Fifth, since the perfect watertightness is ensured at the joint of the concrete pipe (1), there is no fear of reconstruction due to leakage, thereby reducing the overall construction cost.
