Description

Remicon transport carrier system

The present invention relates to a ready-mixed concrete carrier system, and more particularly, a hydraulic pump for rotating the ready-mixed concrete drum forward and backward, running forward and backward on a rail, and receiving power from a power line installed on the ground to rotate the drum with an electric motor; It relates to a ready-mixed concrete cart system that drives a hydraulic motor to rotate the wheels.

The ready-mixed concrete used for pouring concrete in the construction phenomenon is also called raw concrete.

The official name of ready-mixed concrete refers to non-solidified concrete that is transported to a designated place while mixing fresh concrete manufactured at a factory equipped with concrete manufacturing facilities as ready mixed concrete.

A truck mixer or ready-mixed concrete vehicle is used for transport.

Shrink mixed concrete is mixed at the factory to a certain extent and then mixed while transported by a truck mixer, and transit mixed concrete is completely mixed while transporting in a truck mixer from the beginning.

When a truck mixer is used, since ready-mixed concrete can be manufactured by mixing aggregate, cement, water, etc. during transport of the truck mixer, it can be easily poured at the construction site.

On the other hand, precast concrete refers to a product that is pre-fabricated into semi-finished products such as columns, beams, slabs, and walls by placing rebars inside the formwork at a factory and pouring concrete. The semi-finished PC manufactured in this way can be transported to the site and additionally constructed at the site to complete the reinforced concrete structure.

Some semi-finished PC products are long enough to reach several hundred meters, and a plurality of semi-finished PC products can be produced at once by arranging them for a long time. So, it is possible to pour concrete while moving the vehicle at every predetermined location using a ready-mixed concrete vehicle in the manufacturing plant.

However, when pouring concrete in a factory producing semi-finished PC products, a driver drives a ready-mixed concrete vehicle and another person has to operate to pour concrete at a predetermined location, so there is a very cumbersome problem.

In addition, since another person must operate near the ready-mixed concrete vehicle and give a signal to the driver, there is a high possibility of a safety accident.

The ready-mixed concrete carrier system of the present invention is mounted on both sides of the lower side of the vehicle body frame 110, and the driving wheel 164 rotated to run on the rail device 200 installed on the ground, and the power line unit 290 installed inside the rail device. , a power supply device 120 connected to the power line unit to supply power while driving, an electric motor 135 driven by receiving power from the power supply device, and a first hydraulic pressure operated by the electric motor to rotate the driving wheels It includes a first hydraulic pump 141 for rotating the motor 160, and a second hydraulic pump 142 for rotating the second hydraulic motor 170 which is operated by the electric motor to rotate the drum 180.

First, the rail device 200 may be installed so that a pair of rails 210 disposed at a predetermined interval on the ground are exposed. The ground may be constructed by pouring concrete so that the lower part of the rail device 200 is buried.

The ready-mixed concrete carriage 100 is equipped with a pair of driving wheels 164 on both lower and rear sides of the body frame 110 so as to travel on a pair of rails 210, and a pair of driven wheels on both sides of the front ( 166) can be installed. The driving wheel 164 may have a diameter that is approximately three times greater than that of the driven wheel 166 . The pair of driving wheels 164 may be rotated forward and reverse by the first hydraulic motor 160 to travel forward and backward on the pair of rails 210 .

Like the mixer truck, the ready-mixed concrete cart 100 may have a drum 180 inclined at a predetermined angle and may be rotatably mounted. The drum 180 may be rotated forward and reverse by the second hydraulic motor 170 .

As shown in FIG. 3 , an inlet 181 is formed at the rear end of the drum 180 , and a hopper (not shown) may be coupled to the inlet 181 . Concrete may be injected into the drum 180 through the hopper. In addition, a scoop 184 is installed at the lower rear end of the inlet 181 , and a chute 186 may be rotatably installed under the scoop 184 . Concrete discharged from the drum 180 may be put into a predetermined position through the scoop 184 and the chute 186 .

The first hydraulic pump 141 and the second hydraulic pump 142 may be operated by an electric motor 135 mounted in front of the upper surface of the vehicle body frame 110 .

Unlike a ready-mixed concrete vehicle that drives wheels and a hydraulic motor from an engine, the ready-mixed concrete carrier of the present invention receives power from a power line installed on the ground and operates the electric motor to rotate the driving wheels and the drum.

The power line unit 290 may be disposed at a predetermined height between the pair of rails 210 . The power line unit 290 may be disposed closer to one side rather than the center of the pair of rails 210 . A detailed configuration of the power line unit 290 will be described later.

In the ready-mixed concrete carrier 100 of the present invention, the drum 180 extends from the inner circumferential surface and is continuously formed for two or more rotations along the rotation axis of the drum, and a pair of blades 182 arranged to have a phase difference of 180 degrees from each other and the inner circumferential surface It is preferable to include a plurality of mixing protrusions 183 protruding and arranged between a pair of blades to prevent aggregate separation of concrete.

The blade 182 is formed in the form of a curved plate having a predetermined height in the center direction from the inner circumferential surface of the drum 180, and may be formed in a spiral structure as a whole. A pair of blades 182 may be disposed on the inner circumferential surface of the drum 180 to have a phase difference of 180 degrees from each other. Each blade 182 may be continuously formed two or more rotations along the axis of rotation of the drum 180 . Let the length of the axis of rotation of the drum 180 be S, and the distance L of the lead of the blade 182 , that is, the spiral blade 182 moves in the axial direction during one rotation, may be referred to as L. Then, the blade 182 can be formed so that the lead L of the blade 182 satisfies the relational expression of 2L<S<3L. The pair of blades 182 may allow aggregate, sand, cement, admixture, etc. included in the concrete inside the drum 180 to be mixed as the drum 180 rotates. In addition, the pair of blades 182 can move the concrete more easily and quickly toward the inlet 181 when discharging the concrete from the drum 180 disposed at an angle.

On the other hand, although the pair of blades 182 rotate to mix the concrete, the aggregate having a larger specific gravity than the sand may be separated from the sand. In order to prevent such an aggregate separation phenomenon, the drum 180 of the present invention may further include a plurality of mixing protrusions 183 protruding from its inner circumferential surface and arranged between a pair of blades. The mixing protrusion 183 may have a shape of a predetermined thickness, such as a triangle, a square, a semi-circle, or a semi-ellipse, and may be formed to extend in the central direction. The mixing protrusion 183 may be formed in the form of a triangular prism, a quadrangular prism, a triangular pyramid, a hemisphere, or a semi-ellipsoid. The plurality of mixing protrusions 183 may be arranged in different shapes together.

The extension length of the mixing protrusion 183 may be formed to be less than half of the extension length in the center direction of the blade 182 . The plurality of mixing protrusions 183 may be disposed on the inner circumferential surface of the drum 180 to be spaced apart from each other at a predetermined distance. Since the plurality of mixing protrusions 183 are arranged between the pair of blades 182 , the virtual line connecting the plurality of mixing protrusions 183 may also be arranged to have a spiral shape. As the plurality of mixing protrusions 183 are formed on the inner circumferential surface of the drum 180, it is rotated to prevent the aggregate separation of the concrete, so that the concrete can be mixed better.
