[0001] The utility model belongs to the technical field of manhole covers, in particular to a manhole cover with a ladder which is anti-falling and convenient for construction and inspection. Background Art

[0002] Inspection wells are set up for easy installation and maintenance of urban underground infrastructure such as power supply, water supply, drainage, sewage, communications, cable TV, gas pipes, and street light lines. Inspection wells are common facilities in municipal engineering, construction engineering, and other fields.

[0003] Traditional inspection well covers often lack anti-fall devices, increasing the risk of workers falling into the well. In addition, traditional inspection well covers are inconvenient for construction inspection, affecting construction efficiency. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a manhole cover with a fall-proof and convenient construction inspection ladder, which effectively solves the problems raised in the above background.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a manhole cover with an anti-falling ladder and convenient for construction inspection, comprising a fixing ring, a lower flange welded at the lower end of the fixing ring, an upper flange welded at the upper end of the fixing ring, reinforcing ribs welded circumferentially between the fixing ring, the lower flange and the upper flange, a retaining ring symmetrically connected inside the fixing ring, a transverse axis provided between the two retaining rings, the transverse axis connected to the inner wall of the fixing ring, a rotating seat symmetrically sleeved outside the transverse axis, and an anti-falling part connected outside the rotating seat.

[0006] Preferably, the anti-falling component comprises a frame, and the interior of the frame is evenly connected with blocking rods.

[0007] Preferably, a fixing hole is provided on the circumference of the upper end of the lower convex edge, and the fixing hole is a waist-shaped hole structure.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] The utility model can play an anti-falling effect inside by providing the anti-falling part. When it is necessary to inspect and construct the inside of the inspection well, the anti-falling part can be flipped open upwards, and then personnel can climb down from the ladder on the inner wall of the inspection well for inspection and construction. Through the anti-falling part structure that is flipped up and down to open, the device can not only play an anti-falling effect, but also can be quickly flipped open for entry during inspection and construction, which effectively improves work efficiency and has a simple overall structure.

[0015] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0016] Embodiment 1, by Figure 1-Figure 2 The utility model includes a fixing ring 1, a lower flange 2 is welded at the lower end of the fixing ring 1, an upper flange 3 is welded at the upper end of the fixing ring 1, a reinforcing rib plate 4 is welded circumferentially between the fixing ring 1, the lower flange 2 and the upper flange 3, a retaining ring 5 is symmetrically connected inside the fixing ring 1, a transverse axis 6 is arranged between the two retaining rings 5, the transverse axis 6 is connected to the inner wall of the fixing ring 1, a rotating seat 7 is symmetrically sleeved outside the transverse axis 6, and an anti-falling part 8 is connected to the outside of the rotating seat 7;

[0017] The anti-falling member 8 comprises a frame 81, and the interior of the frame 81 is evenly connected with a blocking rod 82;

[0018] A fixing hole 9 is provided on the circumference of the upper end of the lower flange 2. The fixing hole 9 is a waist-shaped hole structure, which is convenient for adjusting the position of the expansion bolt when the device is installed in the inspection well.

[0019] Working principle: When in use, the device is fixedly installed on the upper end of the inspection well, and then the corresponding manhole cover is placed inside the fixing ring 1 to close the inspection well. In the case that the manhole cover is damaged and broken due to pressure for a long time, the anti-falling part 8 of the device can play an anti-falling effect inside. When it is necessary to inspect and construct the inside of the inspection well, the anti-falling part 8 can be flipped upward and opened, and then the personnel can climb down from the ladder on the inner wall of the inspection well for inspection and construction. Through this anti-falling part 8 structure that is flipped up and down, the device can not only play an anti-falling effect, but also can be quickly flipped open and entered during inspection and construction, which effectively improves work efficiency.
