Description

[Detailed description of the invention] This invention is a turret for deep excavation that aims to safely and reliably rotate and carry out the bucket for discharging earth and sand used when excavating earth and sand from the ground surface and installing foundation columns. It is related to the device.

In general, transporting earth and sand out of the house during deep foundation work is extremely dangerous work because the depth gradually increases as the work progresses.

Traditionally, the turret equipment used in this type of deep-depth construction work is to install a tripod or four-leg turret around the core of the excavation location.
A winch is attached to the leg of the turret, and when the winch is rotated, the wire is raised, and a bucket tied to the tip of the wire is raised to lift up and carry out the excavated soil. When the dirt that has entered the tunnel rises above the tunnel entrance, the worker at the tunnel entrance pulls the bucket toward him and overturns the bucket to discharge it. In this case, workers often fall and fall, or even when pulling the worker closer to the site, dirt, etc. often falls into the excavation pit, which is very dangerous, and the buckets that are used to dispose of the dirt by tipping over are very dangerous. The work is very tedious. Additionally, conventional turret frames have drawbacks such as being extremely unstable.

This idea improves on the above-mentioned drawbacks, and its main structure is to create a rectangular turret with pillars made of various types of steel that can be assembled freely, horizontal frames on the front and back, and side frames on the left and right sides. Configure the frame body. Below the main body of the turret frame, a floor plate with connected iron plates etc. will be laid. An opening is formed in the floor plate approximately in the center, and a cutout hole is formed in one end. This opening will be equipped with a protective fence with a folding fence.
Further, a support frame for rotatably suspending the bucket rotor is installed in the cutout hole. Therefore, according to this invention, the protective fence completely prevents the worker from falling and falling, and the movement of the bucket can be achieved reliably and easily without any obstacles, and the excavation ability is extremely fast, and the rotation of the bucket is very fast. The body can easily and reliably perform the reverse discharge and return operation of the earth and sand inside the bucket, which has excellent excavation ability and is effective in achieving sufficient safety for workers.

Next, an embodiment of this invention will be described with reference to the drawings.A turret frame main body 1 made of molded steel having various cross-sectional shapes that can be freely assembled is made up of four opposing pillars 2,
2... is erected in a rectangular shape near the excavation position.
On the pillars 2, 2, several horizontal frames 3, 3... which are horizontal on the front and back, and side frames 4, 4 installed above and below the left and right sides are assembled using attachments such as bolt nuts. Freely configure it. Further, diagonal frames 20, 2 in which the horizontal frames 3, 3 and the lower ends of the pillars 2, 2 are inclined
0, and intersecting diagonal frames 21, 21 are also constructed and connected to the pillars 2, 2 on the side frames 4, 4 side.

Next, at a predetermined position below the turret frame main body 1, a floor plate 5 is installed, which is made by welding several iron plates 9, 9, . . . and connecting them into a rectangular shape. The floorboard 5 is provided with an opening 6 of a required size approximately in the center, and a cutout hole 1 at one end in the longitudinal direction.
0 is formed. A protective fence 7 with an open bottom of a predetermined size is installed at the top of the opening 6, and a folding fence 7 whose upper part facing each other can be opened and closed is installed on the side of the protective fence 7. The fences 11, 11 are foldably installed using hinges 12, 12. Further, in the cutout hole 10 provided on one of the longitudinal ends of the floor plate 5, a rotatable bucket rotor 8 into which a bucket 19 is fitted is inserted into the opposing support frames 13, 1.
The support frames 13, 13, which are rotatably suspended by pivots 14, 14, are fitted into the support frames 13, 3. Further, an elastic body 15 with close contact is attached to the inner wall of the bucket rotor 8.

Furthermore, the side frames 4, 4 at the top of the turret frame main body 1,
A hoist rail 16 is constructed, and on this hoist rail 16 is an electric hoist 17 that can freely wind a wire 18 with a bucket 19 suspended below.
is suspended so that it can slide freely. Incidentally, the turret frame main body 1 is equipped with a ladder or the like at a required position for the worker to ascend and descend. Furthermore, a movable body such as casters may be attached to the lower ends of the pillars 2, 2....

This device has the above-mentioned configuration, and to explain how to use it now, the horizontal frames 3, 3 and side frames 4, 4 are attached to the pillars 2, 2, etc. using bolts and nuts at the mine entrance at the excavation location. The composition is made using a groin. Furthermore, the front and back sides and the left and right side surfaces are composed of diagonal frames 20, 20 and diagonal frames 21, 21. Therefore, the wire 18 that is wound around the electric hoist 17 carries the earth and sand excavated from the excavation hole below the opening 6 of the floor plate 5.
Inject it into the bucket 19 at the bottom, and
is hoisted up from the mine entrance, moved to the bucket rotor 8 by running the electric hoist 17 on the hoist rail 16 at a position substantially above the protective fence 7, and is simultaneously lowered and fitted into the bucket rotor 8. At the same time, the bucket 19 is also overturned to discharge the dirt inside. At this time, the internal bucket 19
is closely supported by the elastic body 15 inside the bucket rotor 8, and only the earth and sand in the bucket 19 is tumbled and discharged without using any special fixing device. Thereafter, the bucket 19 is separated from the bucket rotating body 8 by winding up the wire 18,
The electric hoist 17 is used to descend into the excavation pit from the folding fence 11, which is the original pit entrance, and the work is repeated. Through this work, the trench is excavated in a vertical circle, and concrete is placed at the bottom of the foundation at a predetermined location to form foundation columns.

According to the turret device for deep excavation of this invention, carrying out the earth and sand during deep excavation is a very dangerous work as the work gets deeper as the work progresses. Therefore, there is no danger of earth and sand falling from the pit entrance, and there is an effect that there is no chance of workers falling. A floorboard such as an iron plate is laid below the turret frame body, and an opening is drilled in the approximate center of the floorboard and a protective fence is installed, so the turret frame body is strengthened as a whole. In addition, work efficiency is significantly improved, the protective fence prevents workers from falling, and the operator can move the bucket with confidence. In addition, since the protective fence is provided with a folding fence, the lifting distance of the bucket can be reduced, making it convenient for movement and providing excellent workability.

Furthermore, by installing a support frame that rotatably suspends the bucket rotor in the cutout hole provided at the end of the floorboard, it is possible to reversely release and return the earth and sand inside the excavated bucket. This has the practical effect of allowing the bucket to be rotated at the same time without being fixed to the bucket rotating body each time. Furthermore, this invention has the advantage of being very convenient to move and transport because it can be disassembled and reassembled freely.
