Abstract
Description
Technical Field
[0001] This utility model relates to the field of infrastructure technology, and in particular to a manhole cover reinforcement base for preventing settlement. Background Technology
[0002] Anti-settlement refers to the process or state of preventing or reducing the sinking, settling or uneven settlement of an object due to external loads, changes in geological conditions, material aging, construction defects or other factors through a series of engineering technologies, structural designs or management measures, so as to ensure its normal function, structural safety and service life.
[0003] A manhole cover reinforcement base is a structural device installed around or at the bottom of a manhole cover. Its core function is to solve problems such as settlement, loosening, displacement, abnormal noise, and even damage caused by factors such as vehicle rolling, pedestrian trampling, and geological subsidence during long-term use by enhancing the connection strength and overall load-bearing capacity between the manhole cover and the surrounding road surface and manhole structure. This ensures road traffic safety and improves the stability and service life of infrastructure.
[0004] However, traditional manhole cover reinforcement bases rely solely on the protrusions on the side wall of the mounting base for initial fixation. With few connection points and a small contact area with the ground, the base is prone to gradually sinking due to local compaction of the foundation or loosening of the soil after long-term stress, resulting in a height difference between the manhole cover and the surrounding road surface. Therefore, a settlement-resistant manhole cover reinforcement base is proposed to solve the above problems. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model of manhole covers, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0035] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a manhole cover reinforcement base for preventing settlement, comprising a mounting base 1. The outer sidewall of the mounting base 1 is provided with four sets of protrusions, and the surface of the four sets of protrusions is provided with threaded grooves. These threaded grooves can be used to insert fasteners such as bolts, so that the mounting base 1 can be initially fixed on the ground, providing basic support for the entire device. The surface of the manhole cover body 4 is provided with threaded grooves, which are used to fix and limit the fixing bolt b31, so that the fixing bolt b31 can only rotate within the threaded grooves of the manhole cover body 4. The upper end of the mounting base 1 is provided with the manhole cover body 4, and the surface of the mounting base 1 is provided with a fixing mechanism 2.
[0036] Reference Figure 1 - Figure 3 The fixing mechanism 2 includes a rotating seat 21, which is rotatably connected to the inner side wall of the mounting base 1. The surface of the rotating seat 21 is provided with an inclined groove, which serves to limit and guide the sliding block 22, so that the sliding block 22 can only slide back and forth in the inclined groove of the rotating seat 21. The surface of the mounting base 1 is provided with a straight groove, and the sliding block 22 is slidably connected in the straight groove of the mounting base 1. The straight groove on the surface of the mounting base 1 serves to limit and guide the sliding block 22, so that the sliding block 22 can only slide back and forth in the straight groove on the surface of the mounting base 1. The bottom end of the mounting base 1 is provided with a sliding groove, and the outer side wall of the fixing block 23 is slidably connected in the sliding groove of the mounting base 1. The sliding groove at the bottom end of the mounting base 1 serves to guide the fixing block 23, so that the fixing blocks 23 can only move closer together or further apart in the sliding groove of the mounting base 1.
[0037] Reference Figure 4 - Figure 6A sliding block 22 is slidably connected to the inner wall of the inclined groove on the surface of the rotating seat 21. Rotation of the rotating seat 21 synchronously drives the sliding block 22 to slide within the inclined groove. A fixing block 23 is fixedly connected to the lower surface of the sliding block 22. Sliding of the sliding block 22 synchronously drives the fixing block 23 to slide. A toothed block is provided on the outer arc surface of the rotating seat 21. The toothed block on the surface of the rotating seat 21 meshes with a gear 24. The gear 24 meshes with the toothed block on the outer arc surface of the rotating seat 21. Rotation of the gear 24 synchronously meshes with the rotating seat 21. The outer sidewall of the gear 24 is rotatably connected to the upper surface of the mounting base 1. The mounting base 1 supports the gear 24. The gear 24 is threadedly connected to a fixing bolt a25. The mounting base 1 has a threaded groove on its surface. The bottom end of the fixing bolt a25 is threaded into the threaded groove of the mounting base 1. The fixing bolt a25 is used to fix the gear 24 so that the gear 24 cannot rotate. The threaded groove is used to limit and guide the fixing bolt a25 so that the fixing bolt a25 can only rotate within the threaded groove. The lower surface of the mounting base 1 is fixedly connected to an anti-settlement net 26. The anti-settlement net 26 can prevent the manhole cover body 4 from being washed into the sewer by heavy rain, which plays a double protection role. The surface of the mounting base 1 is provided with a vibration damping mechanism 3.
[0038] Reference Figure 1 , Figure 2 and Figure 7 The vibration damping mechanism 3 includes a fixing bolt b31, with a connecting disc 32 threaded onto the surface of the fixing bolt b31. The connecting disc 32 can simultaneously connect four sets of vibration damping mechanisms 3 to evenly distribute the pressure on the vehicle. A sliding groove is provided on the outer surface of the mounting base 1. The outer wall of the bottom end of the sliding rod 36 contacts the sliding groove at the bottom end of the mounting base 1. The sliding groove of the mounting base 1 serves to limit and guide the sliding rod 36, ensuring that the sliding rod 36 can only slide up and down within the slot of the mounting base 1. The fixing bolt b31 passes through and is threaded into the threaded groove of the connecting disc 32. A connecting block 33 is fixedly connected to the lower surface of the connecting disc 32. The connecting block 33 slides downwards under pressure, and the sliding rod 36 is fixedly connected to the lower surface of the connecting block 33. When the connecting block 33 slides down, it will simultaneously drive the sliding rod 36 at the bottom to slide down. The connecting block 33 is elastically connected to the sliding seat 35 through the spring 34. One end of the spring 34 is fixedly connected to the lower surface of the connecting block 33, and the other end of the spring 34 is fixedly connected to the surface of the sliding seat 35. The function of the spring 34 is to automatically reset the sliding rod 36. The inner wall of the sliding seat 35 has a cavity. The sliding rod 36 is slidably connected in the cavity of the sliding seat 35. The function of the cavity of the sliding seat 35 is to limit and guide the sliding rod 36, so that the sliding rod 36 can only slide back and forth in the cavity of the sliding seat 35. The lower surface of the manhole cover body 4 is in contact with the upper surface of the connecting plate 32. The sliding seat 35 is fixedly connected to the surface of the mounting base 1.
[0039] Working principle: When installing the manhole cover base, first fix the protrusion on the side wall of the mounting base 1 to the ground. After fixing, rotate the gear 24. The rotation of the gear 24 will synchronously drive the meshing tooth block on the surface to rotate, thereby driving the rotating base 21 to rotate synchronously. The rotating base 21 has a sloping groove on its surface. The rotation of the rotating base 21 will synchronously drive the sliding block 22 to slide in the sloping groove. At the same time, the sliding block 22 will synchronously slide in the straight groove of the mounting base 1. The two sets of sliding grooves will squeeze the sliding block 22 away from each other. The sliding block 22 moving away from each other will synchronously drive the bottom fixing block 23 to move away from each other until it is inserted into the soil for fixing. After fixing, rotate the fixing bolt a25 to fix and limit the position. The insertion of the fixing block 23 into the soil can increase the contact area with the ground, increase the grip of the reinforced base on the ground, and make it more solid and less prone to settlement.
[0040] Meanwhile, the repeated rolling of vehicles over the manhole cover body 4 can easily cause the manhole cover body 4 to settle. To address this, a vibration damping mechanism 3 is designed. The vibration damping mechanism 3 has a spring 34 between the manhole cover body 4 and the mounting base 1. When the vehicle rolls over the manhole cover body 4, the manhole cover body 4 slides downward, causing the connecting plate 32 to slide downward. The connecting plate 32 causes the four sets of connecting blocks 33 to slide downward. The connecting blocks 33 simultaneously cause the sliding rod 36 to slide downward. The connecting blocks 33 will compress the spring 34, and the spring 34 will play a buffering role against the pressure caused by the vehicle, effectively reducing the settlement of the manhole cover.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
