Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of manhole covers, in particular to a sinking-proof manhole cover. Background Technique
[0002] In urban construction, manhole covers are an essential infrastructure. A manhole cover is an object used to cover a deep well on the road to prevent people or objects from falling. It can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. Generally, it is circular and can be used in green belts, sidewalks, motor vehicle lanes, docks, alleys, etc. The structure of the manhole cover currently in use is a well seat buried under the road surface and a manhole cover arranged on the well seat.
[0003] However, it still has the following drawbacks in actual use:
[0004] The existing manhole cover uses a double-lock to lock, but there is a possibility of being carried away by a vehicle traveling at high speed, which will cause varying degrees of bumps when the passing vehicle presses over the manhole cover, posing a safety hazard to traffic and reducing the usage experience of residents. Content of the Utility Model
[0005] Technical Solution to be Solved
[0006] The purpose of the utility model is to provide a sinking-proof manhole cover to solve the problem that the existing manhole cover uses a double-lock to lock, but there is a possibility of being carried away by a vehicle traveling at high speed, which will cause varying degrees of bumps when the passing vehicle presses over the manhole cover, posing a safety hazard to traffic and reducing the usage experience of residents as mentioned in the above background technique.
[0007] Technical Solution
[0008] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0009] The utility model is a sinking-proof manhole cover, including:
[0010] A well ring, inside the circumference at the bottom end of the well ring is fixedly connected with a protective net;
[0011] A sinking-proof mechanism, including load-bearing arms equidistantly arranged on the outer circumference of the well ring;
[0012] The bottom outer wall of the load-bearing arm is connected with a triangular support frame. Two holes are symmetrically formed through the load-bearing arm, and there is a skirt at the bottom edge of the well ring;
[0013] The load-bearing arm, the triangular support frame, and the skirt are all cast in one piece.
[0014] Further, it further includes an anti-lifting mechanism, which includes a lock hole penetratingly opened on one side of the well ring near the load-bearing arm. On the outer wall of the bottom end of the well ring on the other side near the load-bearing arm, there are two fixed brackets symmetrically. A fixed seat is welded between the two fixed brackets. The fixed seat is connected to the inner wall of the bottom of the well ring, and a connecting cylinder is movably connected to the top of the fixed seat;
[0015] Further, a rotating shaft is movably connected to the inner circumferential wall of the connecting cylinder. Connecting brackets are sleeved on the outer circumferential walls at both ends of the rotating shaft, and fixing holes are penetratingly opened in the connecting brackets.
[0016] Beneficial effects
[0017] Compared with the prior art, the advantages of the present utility model are as follows:
[0018] First, in the present utility model, one end of the well ring is changed to a fixed and movable type, which is connected to the well ring through a connecting bracket. By installing a fixed shaft in the fixing hole, the connecting bracket is fixed to the well ring. The other end is still fixed to the well ring by installing a lock in the lock hole. When a vehicle rolls over the well ring, through the fixed connection end, it can ensure that the well ring is always firmly connected to the road and can prevent the passing vehicle from lifting the well ring.
[0019] Second, based on the first beneficial effect, by increasing the height of the well ring, the paving thickness of the asphalt concrete is increased. When the vehicle brakes suddenly, the asphalt concrete will not be rubbed off. A triangular support frame is added at the connection between the well ring and the load-bearing arm to solve the problem of easy fracture and improve the overall load-bearing capacity, so that the whole well ring reduces its sinking degree during use, slows down the bump of the passing vehicle, ensures traffic safety, and improves the experience of drivers and passengers.
[0020] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. Brief description of the drawings

[0032] Embodiment 1
[0033] Please refer to Figures 1-4 As shown, this embodiment is an anti-settlement manhole cover, including:
[0034] A manhole cover 1, and a protective net 4 is fixedly connected to the inner circumference of the bottom end of the manhole cover 1;
[0035] The underground well is covered by the manhole cover 1 to prevent residents from falling in, and the items falling into the manhole cover 1 are caught by the protective net for convenient subsequent search;
[0036] An anti-settlement mechanism 2, including load-bearing arms 201 equidistantly arranged on the outer circumference of the manhole cover 1;
[0037] Improve the bearing capacity of the well ring through the load-bearing arm 201;
[0038] The anti-flying mechanism 3 includes a lock hole 301 penetratingly opened on one side of the well ring 1 near the load-bearing arm 201. On the outer wall of the bottom end of the well ring 1 on the other side near the load-bearing arm 201, two fixing brackets 302 are symmetrically welded. A fixing seat 303 is welded between the two fixing brackets 302. The fixing seat 303 is welded to the inner wall of the bottom of the well ring 1. The top of the fixing seat 303 is movably connected with a connecting cylinder 306;
[0039] Install a lock in the lock hole 301 to fix one end of the well ring 1 to the well ring. Support the connecting cylinder 306 through the fixing brackets 302 and the fixing seat 303;
[0040] A rotating shaft 305 is movably connected to the inner circumferential wall of the connecting cylinder 306. Connecting frames 304 are sleeved on the outer circumferential walls at both ends of the rotating shaft 305. Fixing holes 307 are penetratingly opened in the connecting frames 304;
[0041] When the well ring 1 is lifted, since the connecting frame 304 is fixedly connected to the fixing seat 303, the end of the connecting frame 304 close to the rotating shaft 305 is lifted to drive the rotating shaft 305 to rotate, thereby driving the connecting cylinder 306 to rotate. Fix the connecting frame 304 to the well ring by installing a fixing shaft in the fixing hole 307;
[0042] Working principle: One end of the well ring 1 is changed to a fixed and movable type, connected to the well ring through the connecting frame 304, and the connecting frame 304 is fixed to the well ring by installing a fixing shaft in the fixing hole 307. The other end is still fixed to the well ring by installing a lock in the lock hole 301. When the vehicle drives the well ring 1 to lift, the well ring 1 is fixed by the lock, and the other end of the well ring is lifted. The fixing seat 303 drives the connecting cylinder 306 to lift. When the connecting cylinder 306 is lifted, the rotating shaft 305 rotates, so that the connecting cylinder 306 rotates. The connecting cylinder 306 drives the connecting frame 304 to move slightly. And one end of the connecting frame 304 is fixed to the well ring through the fixing shaft. When the vehicle runs over the well ring 1, through the fixed connection at one end, it can ensure that the well ring 1 is always firmly connected to the road, preventing it from being driven by the vehicle. The design of the movable connection allows the well ring 1 to have a certain elasticity when subjected to the pressure of the passing vehicle;
[0043] This step reduces the impact force on the well ring 1 and the road, and can reduce the probability of the passing vehicle flying the well ring 1.
[0044] Embodiment 2
[0045] Please refer to Figures 1-4 As shown, on the basis of the above Embodiment 1, this embodiment further includes:
[0046] A triangular support frame 202 is welded to the outer wall of the bottom of the load-bearing arm 201;
[0047] The load-bearing arm 201 is symmetrically penetrated with two holes 203, and the bottom edge of the well ring 1 is welded with an extension 204;
[0048] The load-bearing arm 201, the triangular support frame 202 and the extension 204 are all cast in one step;
[0049] The more openings there are on the load-bearing arm 201, the smaller the spacing between the plates will be. The distance between the plates determines the stability of the arm when it is subjected to force. Drilling can improve the strength of the load-bearing arm 201, because the holes 203 can disperse the load and increase the force-bearing surface area, thereby making the entire structure more stable. The extension 204 can increase the contact cross-sectional area between the well ring 1 and the well, and can make the bearing force of the well ring 1 more evenly transferred to the contact surface of the well.
[0050] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0051] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
