Description

Technology Field

[0001] The present invention relates to a flattening device for poured concrete, and more specifically, to a flattening device for poured concrete in which an auger screw that performs a primary flattening operation is positioned to be driven in the same direction as the direction of operation so as not to interfere with the forward movement of the device body having the auger screw, and the device body can freely move up and down and forward and backward and left and right according to a set control command signal. Background Technology

[0003] Generally, since concrete consists of a mixture of sand, gravel, and moisture, leveling work must be performed after pouring the concrete when constructing floors of building structures or road surfaces that require leveling.

[0005] To this end, the applicant has proposed the "Leveling Device for Poured Concrete" in Korean Registered Patent No. 10-2729727 (published Nov. 19, 2024). The configuration comprises a device body installed on the rear side of a passenger vehicle body, which moves along a concrete pouring surface, and is equipped with left and right driving units on the left and right sides that perform leveling work on the concrete pouring surface. The vertical height of the device body is adjusted by a body height adjustment means, and the device body is configured to adjust the left and right widths of the left and right driving units by a body width adjustment means.

[0007] However, since this conventional casting concrete leveling device is configured such that the auger screw, which is installed at the bottom of the device body and performs a primary leveling operation by forming a left-right driving unit, moves in the left-right direction perpendicular to the direction of work progress to perform the leveling operation, instantaneous forward movement is impossible. Furthermore, in order to move forward, the process of lifting the device body, moving the vehicle body, then lowering the device body and moving it sideways must be repeated one by one, which is cumbersome and inconvenient, as well as causing a loss of work time. Additionally, since one of the workers must always ride in the vehicle body to monitor the work while driving, there were problems that resulted in inefficiency and reduced economic efficiency.

[0017] The advantages and features of the embodiments of the present invention and the methods for achieving them will become clear by referring to the embodiments described in detail below together with the accompanying drawings.

[0019] However, the present invention is not limited to the embodiments disclosed below but can be implemented in various different forms, and these embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. Throughout the specification, the same reference numerals refer to the same components.

[0021] In describing the embodiments of the present invention, specific descriptions of known functions or configurations will be omitted if it is determined that such detailed descriptions could unnecessarily obscure the essence of the invention. Furthermore, the terms described below are defined in consideration of their functions in the embodiments of the present invention, and these may vary depending on the intentions or practices of the user or operator; therefore, their definitions should be based on the content throughout this specification.

[0023] Hereinafter, a leveling device for poured concrete according to the present invention will be described in detail with reference to the attached drawings.

[0025] FIGS. 1 and 2 are photographs showing the overall configuration of a flattening device for poured concrete according to the present invention, and FIGS. 3 and 4 are magnified photographs showing the primary flattening work unit and the concrete vibration unit of FIGS. 1 and 2. As shown therein, the present invention is composed of a device body (4) having a primary flattening work unit (1), a concrete vibration unit (2), and a secondary flattening work unit (3). The device body (4) is configured to be able to move forward, backward, left, and right by means of a longitudinal movement means (5) and a lateral movement means (6), and to be able to adjust the upper and lower height of the device body (4) by means of a height adjustment means (8).

[0027] To explain this in more detail, the primary leveling work unit (1) is configured such that a pair of auger screws A and B (11) (12) are installed in the longitudinal direction parallel to each other, and the pair of auger screws A and B (11) (12) receive power from a screw drive motor (13) and rotate in opposite directions. When concrete is poured on a road surface or floor surface, the auger screws A and B (11) (12) rotate and move the poured concrete forward to cut it away, thereby performing the primary leveling work. At this time, the left and right reciprocating movement of the auger screws A and B (11) (12) is achieved by a lateral movement means (6) to be described later.

[0029] The concrete vibration unit (2) is configured to evenly mix a mixture of gravel, sand, and aggregates contained in poured concrete using vibration, and is provided on the front side of the primary leveling unit (1). It consists of a pair of rake support bars A and B (21) (22), a plurality of transverse bars (24), a vibration motor (25), and a vibration damping member (26). The rake support bars A and B (21) (22) are provided parallel to each other with a longitudinal spacing and are connected and supported by a plurality of transverse bars (24). A plurality of rakes (23) are provided symmetrically on the outer surface of each of the rake support bars A and B (21) (22) so as to face left and right outward. In addition, a vibration motor (25) is provided on a plurality of transverse bars (24), and a vibration damping member (26) is installed between the front frame (41) of the device body (4) that connects and supports the transverse bars (24) to the device body (4) and the transverse bars (24).

[0031] The concrete vibration unit (2) configured in this manner generates vibration by driving the vibration motor (25), and the vibration is transmitted through the transverse bar (24) to the rake support bars A and B (21) (22), which are symmetrically arranged on the left and right sides of the rake (23), so that the rake (23) vibrates to evenly mix the mixture of gravel, sand, and aggregates contained in the poured concrete. This process allows the internal structure of the concrete to be created and cured more firmly, thereby enabling improvements in durability, impact resistance, etc.

[0033] The second leveling work unit (3) is provided on the rear side of the first leveling work unit (1), and a pair of first compaction rollers (31) are each rotatably provided on both sides behind the auger screws A and B (11) (12) of the first leveling work unit (1), and each first compaction roller (31) is configured to be rotatably supported on the intermediate frame (42) of the device body (4) by the first compaction roller support (32). That is, as the pair of first compaction rollers (31) pass over the concrete pouring surface after the first leveling work is completed, they press and compact the pouring surface, thereby increasing the density of the concrete structure and creating an environment for maintaining hard flatness.

[0035] As described above, the device body (4) is configured to integrally fix and support the first and second leveling work sections (1) (3) and the concrete vibration section (2), and is composed of a front frame (41) that connects and supports the concrete vibration section (2), an intermediate frame (42) that connects and supports the first leveling work section (1), a second leveling work section (3), and a rear frame (43) that connects and supports the third leveling work section (7) to be described later, and the front frame (41), the intermediate frame (42), and the rear frame (43) are formed integrally with each other.

[0037] The longitudinal movement means (5) drives and supports the device body (4) to move forward and backward. A pair of longitudinal drive rails (51) are laid along both longitudinal sides of the work section, and a gate-shaped work bridge (52) is placed on the longitudinal drive rails (51) so that the work bridge (52) having the device body (4) can travel forward and backward along the longitudinal drive rails (51) by the power of the longitudinal drive motor (53). The work bridge (52) has a vertical support (52b) installed at the bottom of the longitudinal drive wheel section (52a) that travels along the longitudinal drive rails (51), and the structure is integrally connected between the left and right supports (52b) to provide a space for installing various related parts and devices.

[0039] The lateral movement means (6) moves together with the longitudinal movement means (5) and drives and supports the device body (4) to enable left and right movement. A lateral drive rail (61) is installed on the lower lateral side of the longitudinal movement means (5), and a lateral drive wheel part (62) that travels along the lateral drive rail (61) is integrally formed with the device body (4) and connected to and supported by the lateral drive rail (61). By receiving power from the forward and reverse rotation of the lateral drive motor (63), the lateral drive wheel part (62) travels along the lateral drive rail (61), thereby enabling the device body (4) to be moved in the left and right lateral directions. In addition, the height adjustment means (8) moves together with the longitudinal movement means (5) and the lateral movement means (6) to adjust the upper and lower height of the device body (4) having the primary leveling work section (1), the concrete vibration section (2), and the secondary leveling work section (3).

[0041] In addition, the device body (4) further includes a third leveling work unit (7) for more firmly compacting the concrete after the second leveling work is completed, wherein the third leveling work unit (7) is rotatably equipped with a second compaction roller (71) on each rear side of the first compaction roller (31) with respect to the direction of work progress, and the second compaction roller (71) is each connected and supported to the rear frame (43) of the device body (4) by a second compaction roller support (72).

[0043] Meanwhile, FIG. 4 is a schematic diagram showing the overall moving means of a flattening device for poured concrete according to the present invention, and FIG. 5 is a schematic diagram showing the height adjustment means of FIG. 4. As shown in the figure, the lateral moving means (6) has a lateral driving motor (63) installed on one side inside the work bridge (52), the lateral driving motor (63) has a lateral driving sprocket (64), a lateral driven sprocket (65) is installed on the opposite side of the lateral driving sprocket (64), and the lateral driving sprocket (64) and the lateral driven sprocket (65) are connected by a lateral driving chain (66).

[0045] And, the first leveling work unit (1), which includes second and third leveling work units that perform leveling work, is connected to the lateral drive chain (66) by the lateral connection unit (67), and the first leveling work unit (1) is movably supported by the lateral drive wheel unit (62) that travels along the lateral drive rail (61). In this state, when the lateral drive chain (66) moves in one direction by the lateral drive motor (63), the first leveling work unit (1) connected to the lateral drive chain (66) also moves left and right in the lateral direction together, and the range of movement is limited by contact of a limit switch not shown.

[0047] Additionally, the height adjustment means (8) is composed of a main lifting drive cylinder (81) that raises and lowers the entire work bridge (52) and a sub lifting drive cylinder (84) that raises and lowers the primary leveling work section (1). The main lifting drive cylinder (81) is installed inside the support (52b) to adjust the overall height of the work bridge (52) by extending the support (52b), and the sub lifting drive cylinder (84) is installed between the upper and lower frames (82) (83) of the primary leveling work section (1) to adjust the upper and lower heights of the auger screws A and B (11) (12).

[0049] Along with this, as shown in FIG. 6, the longitudinal movement means (5) has a longitudinal drive motor (53) installed on one side in a direction perpendicular to the work bridge (52), and the longitudinal drive motor (53) has a longitudinal driving sprocket (54), and a longitudinal driven sprocket (55) is installed on the opposite side of the longitudinal driving sprocket (54), and the longitudinal driving sprocket (54) and the longitudinal driven sprocket (55) are connected by a longitudinal drive chain (56). Then, the work bridge (52) is connected and installed to the longitudinal drive chain (56) by a longitudinal connecting part (57). In this state, when the longitudinal drive chain (56) moves in one direction by the longitudinal drive motor (53), the work bridge (52) connected to the longitudinal drive chain (56) also moves forward and backward in the longitudinal direction, and the range of movement is limited by contact with a limit switch not shown.

[0051] Thus, the present invention arranges the auger screw, which performs the primary leveling operation, to be driven in the same direction as the direction of operation so as not to interfere with the forward movement of the device body equipped with the auger screw, and allows the device body to move up and down and forward and backward and left and right freely according to a set control command signal, thereby ensuring the speed and convenience of the leveling operation for concrete poured on the floor surface of a building structure or a road surface, and further increasing economic efficiency by reducing unnecessary work and manpower.

[0053] Although the device for leveling poured concrete according to the present invention has been described in detail above, this describes only the most preferred embodiment of the present invention and is not limited thereto, but is defined and limited by the appended claims. Furthermore, anyone with ordinary knowledge in this technical field may make various modifications and imitations based on the description in the specification of the present invention, and it will be obvious that such are not outside the scope of the present invention.
