Description

A method of transporting construction materials and an apparatus therefor {Delivering of construction materials and apparatus thereof}

The present invention relates to a construction material transport method and apparatus, and more particularly, to a construction material transport method and apparatus for moving cement, sand, gravel, or cement mortar to a construction site or a concrete pouring site, and the present invention is a construction material that can be transported simply and quickly without leaving any residue on the bottom of the pipe when sending out construction materials without rotation of the transfer pipe or spiral plate by inserting and attaching the spiral plate to the inside of the pipe for transport. It relates to a transport method and an apparatus therefor.

In general, a transfer screw is used to transfer powder or semi-solid and liquid substances, and in particular, a pressure pump is used to transfer liquid substances. As an example of using the pressure pump, as shown in FIG. 1, a concrete pump truck (10; CPT; Concrete Pump Truck) is used to transport ready mixed concrete (REMICON) to a destination in a general construction site.

In the concrete pump truck 10, ready-mixed concrete is transported along the boom that connects the vertical transport pipe 100 and the horizontal transport pipe 100 with an elbow.

When the pressure for supplying ready-mixed concrete is applied to the conveying pipe 100 of the concrete pump truck 10 and then stopped, the ready-mixed concrete falls down by a natural fall in the vertical conveying pipe 100 associated with the boom, but the horizontal conveying pipe 100 ), the ready-mixed concrete is not transported well, and the gravel is concentrated in one place and remains in a specific part in the pipe, so that the inside of the transport pipe 100 in a specific part is blocked. At this time, if the user of the pump truck who does not recognize the clogging of the transfer pipe 100 continuously increases the pressure, a rupture phenomenon may occur at any specific portion of the transfer pipe 100 .

On the other hand, the concrete pump truck 10, which serves to transport the ready-mixed concrete, which is a hard slurry, from the ready-mixed concrete truck to reach the destination at the construction site is composed of a vehicle part, a cylinder part, a hopper part, and a transfer pipe 100.

Here, the conveying pipe 100 is a component that functions as a movement path of the ready-mixed concrete, and the conveying pipe 100 must have abrasion resistance and impact resistance.

The transfer pipe 100 is used to transfer ready-mixed concrete made by mixing cement, water, etc. with high-hardness minerals such as sand, gravel (crushed stone), and reclaimed aggregate, so abrasion is severe and in order to reach the high-rise pouring site Because the ready-mixed concrete is pushed by high pressure, high pressure and impact are applied inside the transfer pipe.

A specific part of the transport pipe 100 due to the high pressure in the transport pipe 100 for transferring the ready-mixed concrete blocks the specific part of the transport pipe 100 and the residue remaining in the specific part cannot be transported in the transport pipe 100 . is ruptured, the ready-mixed concrete leaks out of the transfer pipe 100 and the site is contaminated or the worker may be injured by the leaking ready-mixed concrete.

Therefore, when transferring the ready-mixed concrete to the transfer pipe 100, the development of a technology for transferring the ready-mixed concrete without leaving a residue of the ready-mixed concrete to the transfer pipe 100 has been urgently required.

In addition, a means for transferring cement mortar such as ready-mixed concrete to a transfer screw is also known from the prior art. As a prior art for such a transfer screw, Patent No. 0384926 "Twin Transfer Screw" is disclosed in the Laid-Open Patent Publication (Patent Document) see 1). The prior art discloses a feed screw to which the principle of a working cell movable in the axial direction equal to twice the pitch length is applied. As another prior art for the transfer screw, Utility Model Registration No. 382603 "Transfer screw for dough dough" is disclosed in the Utility Model Registered Gazette (see Patent Document 2). The prior art discloses a feed screw having a first feed screw having a wide pitch interval from the central area and a second feed screw having a narrow pitch interval from the central area.

In particular, the previously known transfer screw of the prior art is characterized in that a spiral-shaped thread is fixedly formed around an axis inside a cylinder-shaped housing. In addition, this type of transfer screw has a disadvantage in that the amount of energy consumed is increased due to the pressure generated between the transfer materials and the pressure applied to the screw by the transfer material. There was a difficult problem with this.

As a technology developed in the prior art in order to solve the problems of the prior art, "a rotary feeder and a cement mortar mixing device having a rotary feeder" of Patent Publication No. 2010-0040565 is disclosed in the Patent Laid-Open (Patent Publication) See literature 3).

In the rotary feeder for mixing and conveying raw materials, as shown in FIGS. 2 and 3, "a rotary feeder and a cement mortar mixing device having a rotary feeder" of the Patent Laid-Open No. 2010-0040565, one side a rotatable cylinder-shaped housing 11 with one side open and the other side open or closed; a conveying screw 12 attached to the inner surface of the housing 11 and extending from one side of the housing to the other side in a spiral shape; and a rotary feeder for mixing and transporting raw materials including a rotary shaft 13 coupled to one side of the housing 11, which reduces energy consumption required for blending and transporting raw materials and enables uniform mixing And it has the advantage of being able to discharge quantitatively.

However, in the conventional techniques described above, only the transfer screw 12 installed in the pipe-type or cylindrical housing 11 rotates or the housing 11 itself rotates together with the rotation shaft 13 to transfer the cement mortar. There is a defect that consumes a lot of energy compared to the amount of transport, and the load on the transport screw is excessive during transport, and the transport screw malfunctions frequently. The thread of the mortar is easily worn, and the thread of the housing and the feed screw is easily worn, resulting in a gap between the screw thread of the housing and the feed screw. At this time, a part of the transferred cement mortar cannot be transferred and remains inside the housing. There was a problem in that the transfer could not be performed smoothly.

As such, when the cement mortar remains in a specific part of the housing, the inside of the housing at a certain part of the lower end of the transfer screw is clogged. At this time, if a user who does not recognize the clogging of the housing continuously increases the pressure of the transfer pump, a rupture phenomenon occurs at the site where any specific cement mortar of the housing is left and accumulated, causing a problem in that the construction is stopped.
