Description

[Detailed Description of the Invention] This invention relates to an excavation turret frame that is movable and can be disassembled and assembled freely, and is used when excavating earth and sand from the ground surface to form foundation columns.

In the past, various types of turret frames have been seen here and there, but these use tripod and four-leg turrets, but since these cannot be disassembled and reassembled, they are very troublesome to move and transport. It has the disadvantage of being time consuming.

In addition, in the case where the turret frame has a floor plate and a protective frame, they are not securely and securely screwed together, and therefore have drawbacks such as being unstable and easily damaged.

Since falling accidents often occur in mines, there is a need for something that can be reliably and firmly disassembled and reassembled.

This idea allows the conventional tower frame to be easily and reliably assembled and disassembled using bolts and nuts, and its main structure consists of four vertical columns made of L-beams facing each other in the front, back, left and right. Set up In front and behind these vertical columns, several horizontal horizontal frames are removably screwed in with bolts. Two upper frames are removably assembled on the left and right sides of the vertical column using bolts and nuts, and a hoist rail for sliding an electric hoist is installed between the upper frames, and several upper frames are attached to the top horizontal frame. The upper frame is assembled by screwing, and the horizontal frame and the lower ends of the vertical columns are assembled and connected by an inclined diagonal frame. In addition, intersecting diagonal frames are removably screwed onto the vertical columns on the left and right sides. Below the turret frame, a floor plate made by welding several iron plates to the frame frame is mounted and screwed to the lower horizontal frame and lower frame.

Additionally, an opening is bored in the center of the floorboard, and cutout holes are formed in the ends. A protective frame that can be disassembled and assembled is mounted and screwed into this opening.

The protection frame is open at the bottom, and has an opening/closing fence that can be freely opened and closed at the top of one of the fence frames, and is rotatably pivoted on a hinge.

Therefore, according to this invention, the turret frame, which has been disassembled on the ground surface at the excavation site, can be easily assembled and excavated at another location, and after the foundation columns are completed, it can be easily disassembled one after another and the entire structure can be assembled. It has the effect of being miniaturized and very convenient for transportation, storage, and reuse.

Next, an embodiment of this invention will be explained with reference to the drawings. Reference numeral 1 indicates a turret frame that can be disassembled and reassembled as a whole. Pillars 2, 2... are erected in a rectangular shape. Several horizontal frames 3, 3 made of L-shaped steel with a horizontal cross section are attached to the vertical columns 2, 2 with bolts 13 and nuts 14 so as to be removably attached to the front and back sides. On the left and right sides of the vertical columns 2, 2, two parallel upper frames 5, 5 are attached to the top with bolt nuts 13,
14 so that it can be assembled freely, and two lower frames 10, 10 are also screwed to the lower part.

A hoist rail 6 for sliding an electric hoist is screwed between the upper frames 5 and 5 in an erected state. Next, several upper frames 4, 4 are installed between the upper frames 5, 5 on the uppermost horizontal frames 3, 3, and are screwed with bolts and nuts. Further, inclined diagonal frames 7, 7 for reinforcement are screwed to the upper parts of the horizontal frames 3, 3 and the lower ends of the vertical columns 2, 2. Further, diagonal frames 7, 7 are removably screwed to the vertical columns 2, 2 on the left and right sides in a crossing manner. A floor plate 8 is installed at a predetermined position below the turret frame 1. This floorboard 8 is
It is constructed by welding several iron plates 17, 17 to the top of several parallel frame frames 16, 16.... This floorboard 8 is mounted and screwed onto horizontal frames 3, 3 located at the front and rear lower portions, and the lower frames 10, 10. Further, the floor plate 8 is provided with an opening 18 of a required size at approximately the center thereof, and a cutout hole 19 at one end in the longitudinal direction. A removable protective fence 9 constructed in a rectangular shape is placed above the opening 18. This protective fence 9 forms an open part 20 at the bottom and also has front and rear fence frames 2, 2.
The left and right fence frames 22, 22 are constructed into a rectangular shape that can be assembled freely using bolts and nuts 26. On one of the fence frames 22, 22, an opening/closing fence 24 and a fixed fence 25, which can be opened and closed at the upper part, are rotatably pivoted by hinges 23, 23.

Further, a lower horizontal frame 11 for reinforcement is installed at the lowest end of the front and rear vertical columns 2, 2, and the vertical columns 2, 2,
The support leg seats 12, 12... are attached to the lower ends of the legs 2, 2.

This device has the above-mentioned configuration, and to explain how to use this device, there are four vertical columns 2, 2... on the top surface of the excavation position, and several horizontal frames 3, 3... on the front and back.
The upper frames 5, 5 at the left and right upper portions and the lower frames 10, 10 at the lower portion are configured to be detachably attached using bolts 13 and nuts 14, respectively. Furthermore, the diagonal frames 7, 7 on the front and back sides are configured to be inclined to the horizontal frame 3 and the vertical columns 2, 2, and the diagonal frames 7, 7 are crossed on the left and right, and both ends are connected to the side surfaces of the vertical columns 2, 2. It is removably screwed onto the body using bolts and nuts. Then, the floorboard 8 is placed on the lower horizontal frames 3, 3 and the lower side frames 10, 10 of the turret frame 1, and screwed together with bolts and nuts so that it can be assembled freely. The frame 9 is screwed onto it. Then, an electric hoist slides on the hoist rail 6 installed between the upper frames 5, 5, and the earth and sand in the bucket is lifted up from the pit entrance of the opening 18 through a cutout hole provided at the end of the floor surface 8. The bucket is moved up to 19 and the soil is discharged by overturning the bucket. At this time, the opening/closing fence 24 of the protection frame 9 is folded open so that the bucket can be operated at a low position.

As mentioned above, according to the prefabricated tower frame of this invention,
It has the excellent effect of being able to be freely disassembled and reassembled in any location where the foundation pillar is being constructed and used multiple times, and it can be disassembled without taking up much space when moved in the assembled state like before. This has the excellent practical effect of making the whole compact, making it very convenient to transport and store. Then, cross-section L
Since it is constructed using shaped steel, it is resistant to bending and is extremely easy to assemble and disassemble, and the constituent materials are extremely inexpensive, making it easy to repair or replace in case of damage. Furthermore, the oblique frames on the front and back sides and the intersecting diagonal frames on the left and right sides make the framework of the turret frame sturdy, increasing the sense of stability as a whole, and also having the effect of functioning as a handrail, etc., as appropriate. Furthermore, the floor plate screwed to a predetermined position below the turret frame allows for stable work, and also has the effect of making the work easier against mud caused by rainwater. This has the effect of stably fixing the protective frame attached to the opening. In addition, the protective frame attached to the floorboard can be assembled and folded, making it extremely convenient.
Furthermore, by making the upper part of one of the fence frames freely openable and closable, there are excellent effects that have not been seen in the past, such as making the workability of the bucket cart extremely quick and efficient.
