Description

Technical Field

[0001] The invention belongs to the technical field of integrated pipe corridors and relates to an escape manhole cover for an integrated pipe corridor. Background Art

[0002] As a method for laying municipal pipelines, the integrated pipeline corridor centralizes various municipal pipelines by constructing a linear underground tunnel structure, leaving space for maintenance and passageways for personnel. The pipelines in the integrated pipeline corridor are centrally arranged, and the laying and maintenance of various pipelines are carried out directly within the integrated pipeline corridor, avoiding the repeated excavation of roads for laying and maintaining underground pipelines, which would disrupt traffic and residents' travel.

[0003] To ensure the safety of workers in underground utility corridors, utility corridors should be equipped with personnel entrances and exits, escape hatches, lifting hatches, air inlets, and pipeline branching hatches. The opening method of utility corridor escape hatch covers differs from that of ordinary municipal manhole covers. In an emergency, they must be able to be opened smoothly from inside the corridor to facilitate escape. Traditional escape hatch covers are flat in structure, and debris easily accumulates on them, affecting their opening and hindering the smooth escape of personnel in the corridor. When the accumulated debris is heavy, it may even prevent the cover from being opened from inside the corridor, resulting in the serious consequence of blocking the escape route for personnel in the corridor. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an integrated pipe gallery escape manhole cover that is not easily accumulated with debris, so as to solve the hidden danger problem that the existing integrated pipe gallery escape manhole cover is easy to accumulate debris, making it difficult to open from the inside of the pipe gallery and blocking the escape passage.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A comprehensive pipe gallery escape manhole cover comprises a base and a cover plate hinged on the base and capable of being opened and closed. The cover plate is provided with a plurality of reinforcing ribs, which are arranged on the outer surface of the cover plate. The height of each reinforcing rib gradually decreases from the center of the cover plate to the edge of the cover plate.

[0007] Furthermore, a drainage outlet is provided on the reinforcing rib.

[0008] Furthermore, the two side surfaces of the reinforcing rib are not parallel to each other.

[0009] Furthermore, the reinforcing ribs are arranged in a crisscross pattern.

[0010] Furthermore, a portion of the reinforcing ribs are arranged in a linear radial pattern from the center of the cover plate to the edge of the cover plate, and another portion of the reinforcing ribs are arranged in a ring-shaped pattern.

[0011] Furthermore, a portion of the reinforcing ribs are arranged in a curved radial shape from the center of the cover plate to the edge of the cover plate, dividing the outer surface of the cover plate into several areas, and another portion of the reinforcing ribs are bent with the bending point tending toward the center of the cover plate, and are arranged correspondingly in the areas divided by the reinforcing ribs arranged in a curved radial shape, and do not intersect with the reinforcing ribs arranged in a curved radial shape.

[0012] Furthermore, a lock core for opening or closing the cover is provided on the outer surface of the cover away from the hinged position of the cover and the base, and a hydraulic cylinder or electric pull rod device for opening or closing the cover is provided on the inner surface of the cover close to the hinged position of the cover and the base.

[0013] Furthermore, a handle is provided on the inner surface of the cover plate away from the hinged position between the cover plate and the base.

[0014] Furthermore, a well ring is provided on the base, a support is provided on the inner wall of the well ring, the cover plate is covered on the support, and one side of the cover plate is connected to the well ring through a hinge device.

[0015] Furthermore, a sealing groove is provided on the support, and a sealing ring is provided in the sealing groove.

[0016] The beneficial effects of the present invention are:

[0017] (1) The reinforced ribs provided on the outer surface of the cover plate of the comprehensive pipe corridor escape hatch disclosed by the present invention not only strengthen the strength of the cover plate and improve the load-bearing and anti-deformation capabilities of the cover plate, but also the raised reinforced ribs form a discontinuous inclined slope with a high middle and low edges on the outer surface of the cover plate. The cover plate with this structure is not prone to accumulation of debris, and the design eliminates the possibility of objects stacked on the cover plate making it difficult to open the escape hatch from the inside and blocking the escape passage, thereby ensuring smooth opening of the cover plate and unobstructed escape passage.

[0018] (2) The escape hatch cover of the integrated pipe gallery disclosed in the present invention has drainage holes between the reinforced ribs for draining rainwater from the cover plate to prevent rainwater from accumulating in the enclosed area of ​​the cover plate formed between the reinforced ribs.

[0019] (3) In the integrated pipe corridor escape manhole cover disclosed by the present invention, the two side surfaces of each reinforced rib are not parallel to each other, which makes it inconvenient to clamp the reinforced rib with a clamp to forcibly open the cover, thereby meeting the requirement that it is difficult for non-professionals to open the cover outside the escape hole.

[0020] (4) The escape hatch cover of the integrated tunnel disclosed by the present invention is convenient for professionals to open or close the cover plate through a lock core outside the tunnel, while preventing non-professionals from opening the cover plate from outside the tunnel, and has a good anti-theft function; inside the tunnel, the cover plate can be quickly opened or closed by a hydraulic cylinder or an electric pull rod device, and in the event of failure of the hydraulic cylinder or the electric pull rod device, the cover plate can also be opened manually using a handle to ensure that the escape passage is unobstructed.

[0027] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] like Figure 1 and Figure 2 As shown, this embodiment provides a comprehensive pipe corridor escape manhole cover, including a base 1 and a cover plate 2 hinged on the base 1 and capable of being opened and closed, the cover plate 2 being provided with a plurality of reinforcing ribs 3, the reinforcing ribs 3 being provided on the outer surface of the cover plate 2, and the height of each reinforcing rib 3 gradually decreasing from the center of the cover plate 2 to the edge of the cover plate 2. The reinforcing ribs 3 provided on the outer surface of the cover plate 2 not only play the role of strengthening the strength of the cover plate 2, improving the load-bearing and anti-deformation capabilities of the cover plate 2, but also the raised reinforcing ribs 3 form a discontinuous inclined slope with a high middle and low edges on the outer surface of the cover plate 2. The cover plate 2 of this structure is not prone to accumulation of debris, and the design eliminates the possibility of the escape passage being blocked due to the stacking of items on the cover plate 2, thereby ensuring the smooth opening of the cover plate 2 and the unobstructed escape passage.

[0029] Specifically, in this embodiment, the reinforcing ribs 3 are arranged in a crisscross pattern, and drainage holes 7 are provided on the reinforcing ribs 3 to prevent rainwater from being retained or accumulated in the enclosed area formed between the reinforcing ribs 3. The two side surfaces of the reinforcing ribs 3 are not parallel to each other, such as Figure 1 As shown, the cross-section of the reinforcing rib 3 is a conical structure that is narrow at the top and wide at the bottom. It is difficult for the clamp to firmly clamp the reinforcing rib 3 to apply an upward force, which can prevent non-professionals from using the clamp to forcibly open the cover plate 2 outside the escape exit, meeting the requirement that it is difficult for non-professionals to open the cover plate 2 outside the escape exit.

[0030] A lock core 8 for opening or closing the cover plate 2 is provided on the outer surface of the cover plate 2 away from the hinged position of the cover plate 2 and the base 1. The setting of the lock core 8 makes it convenient for professionals to open or close the cover plate 2 from outside the escape hatch using a key compatible with the lock core 8 when needed, while it is difficult for non-professionals to open the cover plate 2 from outside the escape hatch, thereby playing an anti-theft role; a hydraulic cylinder or an electric pull rod device for opening or closing the cover plate 2 is provided on the inner surface of the cover plate 2 near the hinged position of the cover plate 2 and the base 1, which facilitates the rapid opening of the cover plate 2 from inside the escape hatch and enables the rapid escape of people in the escape hatch; in addition, a handle is provided on the inner surface of the cover plate 2 away from the hinged position of the cover plate 2 and the base 1, so that the cover plate 2 can be manually opened in the event of a hydraulic cylinder failure or a power failure of the electric pull rod device.

[0031] like Figure 1 As shown, the base 1 is provided with a manhole ring 4, the inner wall of which is provided with a support 5. The cover plate 2 is placed on the support 5, and one side of the cover plate 2 is connected to the manhole ring 4 via a hinge 6. The support 5 is provided with a sealing groove, and a sealing ring is installed in the sealing groove to provide waterproofing. When the integrated pipe corridor escape manhole cover is installed, the top of the manhole ring 4 is flush with the design elevation, and the cover plate 2 has a raised shape due to the reinforced ribs 3 provided on the outer surface.

[0032] Example 2:

[0033] The difference between Example 2 and Example 1 is that the arrangement of the reinforcing ribs 3 is different, wherein three reinforcing ribs 3 are evenly distributed around the circumference of the cover plate 2, and are arranged linearly and radially from the center of the cover plate 2 to the edge of the cover plate 2, and another part of the reinforcing ribs 3 are concentric rings with the cover plate 2, and are arranged in a ring shape with the rings nested inside each other.

[0034] Example 3:

[0035] The difference between Example 3 and Example 1 is that the arrangement of the reinforcing ribs 3 is different, wherein three of the reinforcing ribs 3 are arranged in a curved radial shape from the center of the cover plate 2 to the edge of the cover plate 2, dividing the outer surface of the cover plate 2 into three equal areas, and the other three reinforcing ribs 3 are bent with the bending point tending to the center of the cover plate 2, and are correspondingly arranged in the area divided by the reinforcing ribs 3 arranged in a curved radial shape; the bent reinforcing ribs 3 do not intersect with the reinforcing ribs 3 arranged in a curved radial shape, and there is a certain gap, which serves as a drain outlet 7 to drain rainwater from the outer surface of the cover plate 2.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions, which should all be included in the scope of the claims of the present invention.
