Therefore, they cannot be understood as limitations on the present invention.
[0033] This embodiment discloses an inspection well anti-falling device and an inspection well, which are used to solve the problems existing in the prior art.
[0034] Reference Figure 1A manhole anti-fall device includes a grille component 1, two fixings 2 and two pairs of telescopic components 3. The two fixings 2 are arranged opposite to each other and fixedly connected in a preset manhole seat 100. In this embodiment, the fixings 2 are U-shaped galvanized steel bars. The diameter of the fixings 2 is greater than 22 mm. Both ends of the fixings 2 are anchored in the preset manhole seat 100, and the depth of the fixings 2 is not less than 150 mm. The length exposed in the manhole seat 100 is in the range of 60-70 mm, which is used to provide stable support for the telescopic components 3. One end of each telescopic component 3 is detachably connected to the grille component 1, and the other end is detachably connected to the fixing 2. The four telescopic components 3 firmly fix the grille component 1 through the tension of the spring 32. The telescopic components 3 on the same side of the grille component 1 are arranged at intervals of not less than 170 mm. The telescopic components 3 on both sides of the grille component 1 are mirror-symmetrical to reduce the possibility of the grille component 1 rolling over when the force is uneven.
[0035] Compared with the prior art, the device of the utility model has better structural strength and hydrophobic effect, is not easy to tip over, and is not easy to be washed away by water.
[0036] Optionally, the outer surface of the fixing member 2 is painted with anti-corrosion paint.
[0037] Among them, Figure 1 and Figure 2 As shown, the grille component 1 includes two "L"-shaped main frame members 11, a plurality of transverse rods 12 and a plurality of longitudinal rods 13. The two main frame members 11 are arranged mirror-symmetrically along the longitudinal center axis of the grille component 1, and the plurality of longitudinal rods 13 are arranged at intervals. The main frame members 11 are parallel to and fixedly connected to the longitudinal rods 13. The plurality of transverse rods 12 are arranged at intervals, and the transverse rods 12 are fixedly connected to the plurality of longitudinal rods 13. The main frame members 11 are perpendicular to and fixedly connected to the transverse rods 12.
[0038] Compared with the prior art, the grid component 1 has better structural strength and greater stability when bearing falling objects.
[0039] Preferably, two arc-shaped rods 14 are further provided on both sides of the grille component 1 , and the rod bodies of the arc-shaped rods 14 are fixedly connected to the ends of the plurality of transverse rods 12 , so as to improve the structural strength of the grille component 1 .
[0040] It should be noted that the material of the above-mentioned grille component 1 includes but is not limited to polyethylene or fiberglass, which has the advantages of high strength, light texture, low cost, good support, corrosion resistance and anti-aging. In this embodiment, the thickness of the main frame 11, the longitudinal rod 13 and the transverse rod 12 is 5-6mm, and the width is 40-50mm. The length and number of the main frame 11, the longitudinal rod 13 and the transverse rod 12 are set according to the size of the inspection well.
[0041] In this embodiment, the grille component 1 can be manufactured in one go in a factory to form an integral grille, and the net width of the grille holes of the grille component 1 is 60 mm-100 mm to reduce the possibility of a person's foot getting stuck in the grille component 1 .
[0042] It should be noted that if Figure 3 As shown, this embodiment also discloses an inspection well, which is used in conjunction with the above-mentioned anti-fall device. The inspection well includes a well seat 100 and a well cover 200. The well cover 200 is hinged to the top of the well seat 100. When the well seat 100 is cast, a fixing part 2 is preset in the well seat and is manufactured at the same time as the well seat 100.
[0043] Reference Figure 3 The telescopic assembly 3 includes a hook 31, a connector 33 and a spring 32 made of stainless steel. The hook head of the hook 31 is connected to the crossbar of the fixing member 2. One end of the spring 32 is welded to the hook tail of the hook 31, and the other end is connected to the main frame 11 through the connector 33. After the telescopic assembly 3 is stretched and clamped to the fixing member 2, the device of the utility model forms a firm anti-falling device. When personnel need to enter the inspection well to work, they only need to stretch the hook 31 and release it from the fixing member 2.
[0044] Preferably, to ensure that the hook 31 is firmly hooked to the fixing member 2, the opening arc range of the hook 31 is 180 degrees to 190 degrees, and the opening radius of the hook 31 is 2-3 mm larger than the diameter of the fixing rod.
[0045] Among them, Figure 4 As shown, the connecting member 33 includes a bolt 331, a washer 332 and a nut 333. The bolt 331 penetrates the end of the spring 32, the washer 332 and the main frame 11 in sequence and is connected to the nut 333. In this embodiment, the washer 332 can be 1-3 pieces, which are used to raise the spring 32 and the hook 31 to facilitate the stretching and scaling of the telescopic assembly 3. The connecting members 33 are all galvanized to enhance the anti-corrosion effect and ensure the durability of the connecting members 33.
[0046] The working principle of the embodiment of the utility model is:
[0047] During the construction of the utility model, the U-shaped Φ22 galvanized steel bar fixing member 2 is first embedded in the concrete well seat 100, the grille member 1 and the telescopic assembly 3 can be prefabricated in advance, and only the spring 32 and the main frame member 11 need to be fixed with the connecting member 33, without the need for on-site secondary processing. The installed grille member 1 can "support" the inspection well mouth, thereby avoiding the occurrence of falling casualties.
[0048] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
