Description

[Detailed explanation of the invention] (Industrial application field) This invention is a drop-in device that is installed at the bottom of a grid-like cover called a grating, which is installed in ventilation holes such as underground power distribution line tunnels and underground holes. This invention relates to a garbage receiving device with prevention.

(Prior art) This type of conventional garbage receiving device has a garbage receiving member support made of an appropriate angle material or long steel material installed near the upper edge of both side walls of a tunnel, etc., and a wire mesh attached to the frame. A flat garbage receiving member covered with a net or the like was installed on top of this support to receive the garbage from above that had passed through the grating at the top.

(Problems to be Solved by the Invention) However, such conventional garbage receiving devices have the following problems. That is, when discharging the received garbage and cleaning the net, etc., there was an inconvenience in that the garbage receiving member could not be taken out unless the entire upper grating was first removed.

Moreover, while the drainage and cleaning work was being carried out elsewhere, all of the tunnels had been crossed and exposed.
There was a danger that people or objects could fall into the cave.

(Means for solving the problem) This idea was made in view of the above points, and it is possible to take out the garbage receiving member outside without removing the entire grating, and moreover, it is possible to move all the garbage receiving members to another location. The purpose of the present invention is to solve this problem by providing a safe garbage receiving device with a fall prevention function that prevents the entire tunnel from being exposed while the garbage is being removed.

Therefore, in this invention, a plurality of dust receiving members equipped with air permeable dust receiving members such as punched metal, wire mesh, and netting are connected in a detachable manner, and are installed near the top of both side walls of tunnels, ventilation holes, etc. The above-mentioned dirt receiving member is installed so that it can slide freely on the set appropriate rail body, and furthermore, the falling object receiving member that extends between the above-mentioned rail bodies is placed below the above-mentioned rail body over an appropriate length. It is characterized by being located nearby.

(Function) Since each dust receiving member is mutually removable and can be slid on the rail body, it is possible to pull it up one by one from one place and remove it.
When removing the grating, all the dust receiving members can be removed by removing the grating by the minimum necessary space, that is, the length of one dust receiving member.

Moreover, during the removal and cleaning work of the garbage accumulated in the garbage receiving member, the part where the tunnel was exposed,
This area corresponds to a part of the installed grating, and by passing a rod to catch falling objects in this area, it is possible to prevent people and objects from falling into the tunnel from above.

Also, when the dust receiving member is returned to its original position and installed again, it is sufficient to install one dust receiving member and slide the dust receiving member by pushing it inward one after another.

(Example) Hereinafter, an example of this invention will be described with reference to the drawings.

In FIG. 1, numerals 1 and 2 are inverted L-shaped long steel members fixed to the side wall of the tunnel, and as shown in FIG. 2, the fixation to the side wall 3 was based on a hawk cut anchor 4. Rail bodies 5 and 6 made of ultra-high molecular weight polyethylene are installed on the upper surfaces of the long steel members 1 and 2. Further, L-shaped short steel members 8 and 9 are fixed to the side wall of the tunnel groove below one side of the long steel members 1 and 2 that is on the side of the climbing ladder 7 in the tunnel, and the upper surfaces of the short steel members 8 and 9 are also fixed. Rail body 1 made of ultra-high molecular weight polyethylene
0 and 11 are installed.

As shown in FIG. 4, on top of the rail bodies 10, 11, a truss body 14 for catching falling objects, consisting of a plurality of vertical rams 12 and a plurality of lateral rams 13, is slidable on the rail bodies 10, 11. It is placed as shown. The four sides of this rod 14 are L-shaped rods 1.
5. 16,1
Reference numeral 7 denotes a horizontal garbage receiver protruding from the rod 14, and each horizontal garbage receiver 16, 17 has a handle 16a, 17.
a is attached, and furthermore, a punching metal 18 is stretched on the horizontal surface.

A first dust receiving member 1 is disposed on the upper surface of this rod body 14.
9 is placed on the first dust receiving member 1.
9 has sleeves 19a on both sides as shown in FIG.
A punching metal 20 is attached to a frame body 19b whose longitudinal center longitudinal section is substantially mountain-shaped, and a handle 21 is fixed to the end of the sleeve 19a. Therefore, by holding the handles 16a and 17a and moving the rod body 14, the first
The dust receiving member 19 also slides. Furthermore, body 14
A rail body 14 is provided at both ends of the lower surface of the rail body 10, 11.
A long guide rod 14a is firmly fixed to prevent it from falling off when sliding.

Therefore, the second dust receiving member 2 in this embodiment
As is clear from FIG. 1, 2, 23, 24, and 25 are generally similar in shape to the first dust receiving member 19. For example, in the case of the first dust receiving member 22, the sleeves 22a on both sides are A punching metal 26 is attached to a frame body 22b which has a longitudinal central vertical section having a substantially chevron shape, and a handle 27 is fixed to the end of the sleeve 22a. A connecting member 28 as shown in FIGS. 6 and 7 is fixed to the end frame 22b. This connecting member 2
8 is constructed by bending one side at a right angle and bending the other side into an R shape, and the inner surface of the end on the right angle side is fixed to the upright side of the frame body 22b. With this configuration, the second dust receiving member 22 is removably connected to another adjacent second dust receiving member 23. That is, if the second dust receiving member 22 moves in the direction of the arrow shown in FIG. , the R side end thereof is connected to the frame 23 at the end of the sleeve 23a of the second dust receiving member 23.
Climb over b and fit into place to lock it. Concatenation is done in this way. When attaching and detaching, all that is required is to hold the handle 27 and lift the second dirt receiving member 22 upward.

Each second dust receiving member 2 configured as described above
2, 23, 24, 25 are slidably placed on the rail bodies 5, 6. As shown in FIG. 8, the second dirt receiving members 22, 23, 24, 25 are set so as to be able to slide freely on the rail bodies 5, 6 below the gratings 30, 31, 32 at the upper part of the tunnel groove. Also, the first dust receiving member 1
As is clear from FIGS. 1 and 8, they are polymerized with each other and can slide freely relative to each other. That is, the first dust receiving member 19 is arranged to fit under the second dust receiving member 22.

The present embodiment has the configuration as described above, and the dust from above that has passed through the gratings 30, 31, 32 is transferred to each of the punching metals 26 of the second dust receiving members 22, 23, 24, 25 and the first dust receiving member. Part 19
The punched metal 20 is received. At this time, each of the punching metals 26 and 20 has a substantially chevron-shaped center, so that the received garbage does not accumulate and slides down the slope, leaving the sleeves 22 on both sides.
a, 19a, etc. Therefore, the slope portions of each punching metal 26, 20 can always maintain a good ventilation function without becoming clogged. In addition, the ventilation function itself has a larger surface area than conventional planar ones, allowing for a greater amount of ventilation.

Also, second dust receiving members 22, 23, 24, 25
When cleaning the grating 30, remove the grating 30 from one end and pull the grating 30 upward from there. Furthermore, when the first dust receiving member 19 is removed, the tunnel 14 is located on the bottom surface, so the tunnel will not be exposed, and even if someone falls from the place where the grating 30 is removed, the body 14
It is safe to receive it.

Thus, the cleaning work is completed, and the second dirt receiving member 22 is removed.
When restoring things, etc., you can easily do it by reversing the steps. That is, the second dirt receiving member 25 is first placed on the rail body 5,
6 and slide it to the back, and then place the remaining second dirt receiving members 25, 24, 23, and 22 on the rail bodies 5 and 6 in order and push them to the back and slide them, the connecting member 28 automatically connects each second dirt receiving member.

Furthermore, in this embodiment, the rail bodies 5 and 6 have bell-shaped longitudinal sections, as is clear from FIGS. The sliding of the receiving member 22 and the like is not hindered. Therefore, smooth sliding over a long period of time is ensured.

(Effects of the invention) According to this invention, the work space required for taking out the garbage receiving member to the outside and installing it on the rail body is the minimum required, that is, the width and length of one garbage receiving member is sufficient. Therefore, even when removing the grating on the upper part, by appropriately setting the length of the dust receiving member, it is only necessary to remove one grating, which speeds up the work.

In addition, in such cases, the only part of the exposed tunnel, etc. is that of this single piece of grating, and by passing a rod to catch falling objects in this part, it is possible to prevent people or objects from falling into the tunnel. There is nothing to do and it is extremely safe.

In addition, taking out the above-mentioned garbage receiving member to the outside,
The practical effects of this invention are extremely high, as the installation work itself is easy and smooth.
