The terms used in the embodiments are general terms that are currently widely used as much as possible while considering the function in the present invention, but this may vary depending on the intention or precedent of a person working in the art, the emergence of new technology, etc. In addition, in certain cases, there are terms arbitrarily selected by the applicant, and in this case, the meaning will be described in detail in the description of the relevant invention. Therefore, the terms used in the present invention should be defined based on the meaning of the term and the overall content of the present invention, rather than simply the name of the term.

When it is said that a part “includes” a certain element throughout the specification, this means that it does not exclude other elements, but may further include other elements, unless specifically stated to the contrary.

Below, with reference to the attached drawings, embodiments of the present invention will be described in detail so that those skilled in the art can easily implement the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein.

Hereinafter, the present invention will be described in detail based on the accompanying drawings.

Figure 1 is a partial cross-sectional view schematically showing one side of the tray mechanism according to the present invention installed in an underground pipe, and Figure 2 is a front view schematically showing the holder of the tray mechanism according to the present invention connected to another neighboring holder. , Figure 3 is an exploded perspective view of the loop in the tray mechanism according to the present invention, and Figure 4 is a perspective view of the tray mechanism according to the present invention.

Referring to Figures 1 to 4, the tray mechanism (T) according to the present invention includes a holder 10, a loop 90, a support beam 20, a pair of supports 30, and a pair of suspension rods ( 40), a winch 50, a hook 60, an idler 70, and a pair of anchor rings 80. The tray mechanism (T) equipped with the above components prevents falling water from the underground pipe (B) from falling into the underground distribution line (C), causing accidents such as short circuits or electric leaks, and prevents the bottom of the underground pipe (B) from falling (G). The underground distribution line (C) located at ) can be safely placed on the holder (10) using the winch (50).

In this embodiment, two tray devices (T) may be installed in the underground pipe (B) as shown in FIG. 1, but the number and location of the tray devices (T) installed in the underground pipe (B) are not limited to this embodiment. No, it can be modified in various ways.

As shown in Figure 2, since the length of the holders 10 of the tray devices T1 and T2 is not infinite, a plurality of them are arranged in a row to mount the underground distribution line C. Typically, the holders 10 of the adjacent tray mechanisms T1 and T2 are integrally connected without gaps, but in this embodiment, they are shown to be separated from each other.

Below, each of the above-described configurations will be described in more detail.

The holder 10 includes a pair of support panels 11 arranged in parallel with each other, and a plurality of rungs 12 arranged in parallel and connecting the pair of support panels 11 spaced apart. As is well known, the support panel 11 performs a fence function to prevent one or more underground distribution lines C mounted on the holder 10 from escaping. The rung (12) connects a pair of support panels (11) spaced apart from each other, and supports one or more underground distribution lines (C) located between the pair of support panels (11). Since the holder 10 is a well-known device in the distribution line wiring field, additional description of the structure, material, and form of the holder 10 will be omitted.

The loop 90 is tilted so that falling water flows in the direction of the front or rear support panel 11, covers the space between the pair of support panels 11, and has a plurality of drain lines 911 formed in the tilted direction. ), a pair of elevation plates 92 extending vertically and protruding from each of the front and rear sides of the upper plate 91 to cover the outer surfaces of each of the pair of support panels 11 and secure the upper plate 91, and the upper plate ( A drainage channel (93) formed to protrude from the elevation plate (92) is provided to collect falling water moving on 91 and flow in the longitudinal direction of the holder (10).

Ultimately, the loop 90 can cover the top of the holder 10 in a detachable manner, so there is no inconvenience caused by the loop 90 when installing the underground distribution line (C), and water falling from the ceiling of the underground pipe (B) is eliminated. By blocking the inflow into the holder (10), it is possible to prevent short circuits and electric leaks in the underground distribution line (C) caused by falling water. Since the falling water is collected at one point through the drainage channel (93) and drained together, drainage treatment is required. It's efficient. Furthermore, since the drain line 911 is formed on the top plate 91 that covers the holder 10, the falling water that falls on the top plate 91 flows into the drain channel 93 without dispersion, contributing to smooth drainage.

For reference, since the support 30 protrudes from the support panel 11 of the holder 10 due to its own thickness, it is preferable to form a pair of elevation plates 92 to cover each of the pair of supports 30 so as to be in close contact with them. do.

Figure 5 is an exploded perspective view of the mounting assembly of the tray mechanism according to the present invention, and Figure 6 is a side view of the structure formed by combining the mounting assembly.

Referring to FIGS. 1, 4, and 5 to 6, the support beam 20 of the tray device T according to the present invention is formed with a hollow opening line 21 in the longitudinal direction and has a pair of supports. It is disposed laterally on the holder 10 so that both ends protrude while supporting the panel 11.

The support beam 20 has a hollow structure so as to sufficiently support the heavy holder 10 on which one or more underground distribution lines C are mounted, and both ends protruding from the holder 10 each have a suspension bar 40. ) is connected to. Ultimately, since the holder 10 is supported by the support beam 20 without being directly connected to the suspension rod 40, the holder 10 can be easily replaced and the operator can conveniently maintain and manage the holder.

The support 30 includes a horizontal plate 31 that covers the upper surface of the end of the support beam 20 protruding from the holder 10, and a horizontal plate 31 at one end of the horizontal plate 31 to closely cover the front surface of the support panel 11. A first elevation plate 32 extending vertically upward, an upper plate 33 extending horizontally from the first elevation plate to tightly cover the upper surface of the support panel 11, and an end portion of the support beam 20. A second elevation plate ( 34) and a pair of side plates 35 extending vertically downward from both ends of the horizontal plate 31 so as to tightly cover both sides of the end of the support beam 20. Since the pair of supports 30 are respectively engaged with a pair of support panels 11 forming the holder 10, they limit the forward and backward and vertical movement of the holder 10 as well as the front and rear, left and right movements of the support beam 20. and restricts vertical movement. To explain this in more detail, the horizontal plate 31 covers the upper surface of the end of the support beam 20 through which the suspension bar 40 penetrates, thereby preventing the upward movement of the support beam 20. Since the first elevation plate 32 covers the front of the support panel 11, a pair of supports 30 prevent the holder 10 from moving back and forth. Since the upper plate 33 covers the upper surface of the support panel 11, it prevents the upward movement of the support beam 20 together with the horizontal plate 31. The front part 341 of the second elevation plate 34 covers the front of the support beam 20 and thus prevents the back and forth movement of the support beam 20. Meanwhile, the bobbin 51 (see FIG. 7) is rotatably installed in the suspension portion 342 extending downward from the bottom of the front portion 341. The pair of side plates 35 cover both sides of the support beam 20 and thus prevent the support beam 20 from moving left and right. Ultimately, the tray mechanism (T) of the present invention completely suppresses the movement of the holder (10) and the support beam (20) with two supports (30) and supports the bobbin (51) of the winch (50).

The upper end of the suspension rod 40 is fixed to the ceiling of the underground pipe (B), and the lower end primarily penetrates the horizontal plate 31 and secondarily penetrates the end of the support beam 20 through the opening line 21. This forms a fixed pair. In this embodiment, the lower end of the suspension bar 40 forms a bolt structure and is screwed to the horizontal plate 31 and the support beam 20 through a nut or the like. Ultimately, the suspension bar 40 is combined with the horizontal plate 31 and the support beam 20, and the support beam 20 stably supports the holder 10, and in addition, the support beam 30 supports the support beam 20. ) to form one unity.

Figure 7 is an exploded perspective view between the stationary assembly and the winch type assembly, Figure 8 is an exploded perspective view showing the hook of the tray mechanism according to the present invention connected to a rope, and Figure 9 is a winch of the tray mechanism according to the present invention. This is a front view sequentially showing the process of the assembly lifting the underground distribution line to the stand.

Referring to Figures 7 to 9, the winch assembly of the tray mechanism (T) according to the present invention consists of a winch (50), a hook (60), and an idler (70). To describe each configuration in more detail, the winch 50 has a fence-type flange 511 formed at each end, winds a rope R, and has a bobbin 51 rotatably installed on the suspension portion 342. ) and a drive motor 52 consisting of a rotating shaft 521 connected to transmit power to the bobbin 51. In this embodiment, the central outer diameter of the bobbin 51 is relatively smaller than the outer outer diameter so that the rope R is concentrated in the center. As a result, since the rope (R) is not distributed or biased around the relatively long bobbin (51), the worker can more easily place the underground distribution line (C) throughout the holder (10). Meanwhile, so that the relatively heavy bobbin 51 is stably connected to the suspension portion 342, a reinforcing plate 343 is additionally configured on the suspension portion 342, and a bobbin rollable installed on the suspension portion 342 ( A bearing 36 may be additionally configured between the suspension 342 and the bobbin 51 so that 51) rotates smoothly.

The drive motor 52 of the winch 50 according to the present invention rotates the rotation shaft 521 connected to the bobbin 51. The driving motor 52 is turned on and off by an operator operating a switch (not shown) in the field. Since the drive motor 52 enables bidirectional rotation of the rotation shaft 521, the rope R wound around the bobbin 51 can be unwound and wound. The drive motor 52 is preferably a direct current motor for bidirectional rotation, but is not limited thereto.

The hook 60 includes a rotor 61 and a rolling shaft 621 connected to allow the rotor 61 to rotate idly, and includes a fixture 62 connected to the end of the rope R. The hook 60 is in the form of a ring that can hang the underground distribution line (C) located on the floor (G), and a rotor 61 is formed at the end. In this embodiment, the fixture 62 connected to the rotor 61 constitutes the rolling shaft 621, so the rotor 61 has a rolling hole (not shown) into which the rolling shaft 621 is inserted. . The fixture 62 is detachably connected to the end of the rope R, and the rolling shaft 621 is inserted into the rolling hole and connected to enable idling. Accordingly, the hook 60 is rotatably connected to the rope R, so even if the rope R is twisted in the process of being wound or unwound from the bobbin 51, the fixture 62 and the rotor 61 rotate idly. , the hook 60 maintains its position and lifts or pulls the underground distribution line (C) without rotation.

The idler 70 is equipped with a roller 71 and a fixing pin 72 that connects both ends of the roller 71 to a pair of support panels 11 so as to rotate freely. The roller 71 of the idler 70 freely rotates on the support panel 11 without external power, and as shown in FIG. 9, the rope R drawn from the bobbin 51 passes through the idler 70 to the floor G. It is suspended as Ultimately, the underground distribution line (C) caught on the hook (60) moves toward the idler (70) along with the winding of the rope (R), as shown in (a) and (b) of FIG. 9. In addition, when the bobbin 51 continues to wind the rope R, the underground distribution line C reaches the upper surface of the holder 10 via the roller 71, as shown in (c) of FIG. 9, and the operator Pull the underground distribution line (C) that has reached (10) and place it in the desired location. Therefore, the worker does not have to lift the underground distribution line (C) up to the stand (10) by manpower, and through this, the labor load can be minimized.

Figure 10 is a perspective view showing the anchor ring of the tray mechanism according to the present invention installed in an underground distribution line, Figure 11 is a perspective view of the anchor ring constructed in the tray mechanism according to the present invention, and Figure 12 is the anchor ring It is a front view schematically showing the operation of the ring, and Figure 13 is a side view schematically showing a hook hanging on an underground distribution line on which the anchor ring is installed.

10 to 13, the anchor ring 80 of the tray device T according to the present invention includes a first hook 81, a second hook 82, and a hinge shaft 83. To explain the anchor ring 80 in more detail, the hook 60 is a kind of ring for lifting the underground distribution line (C) to be placed on the holder 10 from the floor (G), so during the process of raising the underground distribution line (C) C) can slide down from the hook due to its own weight. Therefore, a means is required to prevent the underground distribution line (C) hung on the hook (60) from slipping. The first hook 81 of the anchor ring 80 has a semicircular shape with a first fixing flange 811 formed at one end, and the second hook 82 is a second hook 82 that is fixably in contact with the first fixing flange 811. The fixing flange 821 has a semicircular shape formed at one end, and the hinge shaft 83 rotatably connects the other ends of the first hanger 81 and the second hanger 82. Ultimately, the first hanger 81 and the second hanger 82 unfold or fold around the hinge axis 83 as shown in Figure 12, and when folded, they form a ring shape surrounding the circumference of the underground distribution line (C).

The outer surface of the underground distribution line (C) is insulated to prevent short circuits and leakage. In general, the insulating coating is made of flexible rubber or synthetic resin for bending of the underground distribution line (C), so when force is applied to the surface of the coating, it is deformed. In this embodiment, the inner diameter of the anchor ring 80 is smaller than the outer diameter of the underground distribution line (C), so that when the anchor ring 80 is folded, it strongly bites the circumference of the underground distribution line (C). Ultimately, the anchor ring 80 is immovably fixed to one point of the underground distribution line (C).

Meanwhile, the pair of anchor rings 80 are arranged to be spaced apart at a length corresponding to the thickness of the hook 60, and the hook 60 is inserted between the pair of anchor rings 80 as shown in FIG. 13 to ensure underground distribution. Place the line (C). Ultimately, since the hook 60 is caught by the pair of anchor rings 80 and does not slip, the hook 60 can stably hook and lift the underground distribution line C.

For reference, the first hanger 81 and the second hanger 82 are fixed by inserting bolts into the first fixing flange 811 and the second fixing flange 821, respectively, so the anchor ring 80 is in a folded state. can be maintained, and when the underground distribution line (C) is lifted up to the holder (10), the anchor ring (80) can be unfolded and separated from the underground distribution line (C).

The cross-sectional representation of the underground distribution line (C) shown in FIG. 10 does not directly express the internal shape of the underground distribution line (C), but merely symbolically expresses that the underground distribution line (C) is a single line.

Although the detailed description of the present invention described above has been described with reference to preferred embodiments of the present invention, those skilled in the art or those skilled in the art will understand the spirit of the present invention as described in the patent claims to be described later. It will be understood that the present invention can be modified and changed in various ways without departing from the technical scope.
