Description

Technical Field

[0001] This utility model relates to the field of well perimeter reinforcement technology, and in particular to a well perimeter reinforcement structure for anti-settlement manhole covers. Background Technology

[0002] Manhole covers are facilities used to cover the openings of manholes on roads or other locations. They are usually made of cast iron, steel, composite materials, etc. They prevent pedestrians and vehicles from falling into the manholes, avoiding safety accidents and protecting people's lives and property. At the same time, they also prevent debris and garbage from falling into the manholes, avoiding blockage of pipes or affecting the normal operation of underground equipment.

[0003] Currently, existing manhole covers are mainly composed of components such as the manhole base and the manhole cover. After long-term use, the contact surfaces between the manhole cover and the manhole base will gradually wear down due to friction, causing the originally tight fit to loosen and the gap between the two to increase. This can easily cause the manhole cover to bounce, which will cause vibration of the surrounding road surface. Over time, this may lead to cracks and loosening of the road surface, and eventually, the manhole cover will settle, affecting traffic safety. To address this issue, we propose an anti-settlement manhole cover perimeter reinforcement structure. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a structure for reinforcing the perimeter of anti-settlement manhole covers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A settling-prevention manhole cover perimeter reinforcement structure is installed on a manhole base, which covers the manhole cover body. A support ring is fixedly welded to the inner wall of the manhole base, and the height of the support ring is lower than that of the manhole cover body. A hole is opened at the center of the manhole base, and the upper diameter of the hole is larger than that of the lower diameter. L-shaped plates are evenly distributed inside the hole, and a reinforcing rod is provided on the side of the L-shaped plates that are far apart from each other. The reinforcing rod is inserted into the inside of a U-shaped frame, and the top of the U-shaped frame is fixedly connected to the inner wall of the manhole base. Insertion grooves adapted to the reinforcing rods are opened inside the manhole cover body and the support ring. A limiting rod is vertically inserted inside the L-shaped plate, and a connecting plate is fixedly connected to the top of the limiting rod. A limiting groove adapted to the limiting rod is opened inside the manhole base.

[0007] Preferably, a spring is vertically connected to the bottom end of the connecting plate, and the other end of the spring is connected to the inner wall of the hole.

[0008] Preferably, the sides of the L-shaped plate are respectively connected to mating blocks, and the end of the reinforcing rod is provided with a connecting groove that matches the mating block. The sides of the reinforcing rod are connected to the mating blocks by bolts.

[0009] Preferably, the outer wall of the reinforcing rod is symmetrically glued with rubber sheets, and the outer wall of the rubber sheets is in contact with the inner wall of the U-shaped frame.

[0010] Preferably, a connecting sleeve is inserted into the hole, and the outer surface of the connecting sleeve is provided with external threads, while the inner wall of the hole is provided with internal threads that are compatible with the connecting sleeve.

[0011] Preferably, a groove is provided at the center of the connecting sleeve, and the groove is configured as an elongated strip structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This device, equipped with reinforcing rods and L-shaped plates, can limit and reinforce the perimeter of the manhole cover by inserting the reinforcing rods into the manhole cover body during use. This effectively prevents the manhole cover from jumping during use and prevents the manhole cover from settling and causing road surface height differences that could lead to traffic accidents.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A settling-prevention manhole cover reinforcement structure is installed on a manhole base 1, which covers the manhole cover body 2. The manhole base 1 and the manhole cover body 2 are rotatably connected to meet the opening and closing requirements of the manhole base 1. The specific connection method between the two is existing technology and will not be described in detail here. A support ring 3 is fixedly welded to the inner wall of the manhole base 1, and the height of the support ring 3 is lower than that of the manhole cover body 2. A hole 4 is opened at the center of the manhole base 1, and the upper diameter of the hole 4 is larger than that of the lower diameter. Since the upper diameter of the hole 4 is larger than that of the lower diameter, it can accommodate L-shaped plates 5. L-shaped plates 5 are evenly distributed inside the hole 4, and a reinforcing rod 6 is provided on the side of the L-shaped plates 5 that is far away from each other. The reinforcing rod 6 is inserted into the inside of a U-shaped frame 7, and the top of the U-shaped frame 7 is fixedly connected to the inner wall of the manhole base 1. Next, the U-shaped frame 7 with its U-shaped structure can be used to guide and limit the reinforcing rod 6 laterally. The inside of the manhole cover 2 and the ring 3 is provided with an insertion slot that matches the reinforcing rod 6. The inside of the L-shaped plate 5 is provided with a vertically inserted limiting rod 8, and the top of the limiting rod 8 is fixedly connected to a connecting plate 9. The inside of the manhole seat 1 is provided with a limiting groove that matches the limiting rod 8. With the combination of the limiting rod 8, the connecting plate 9 and the limiting groove inside the manhole seat 1, the reinforcing rod 6 inserted inside the manhole cover 2 and the ring 3 can be limited. When the manhole seat 1 covers the manhole cover 2, each set of reinforcing rods 6 will be inserted into the corresponding limiting groove. When it is necessary to open the manhole seat 1, the operator can pull out the ends of each set of reinforcing rods 6 from the inside of the limiting groove to release the limiting work on the manhole seat 1.

[0023] Furthermore, refer to Figure 4 It can be seen that the bottom end of the connecting plate 9 is vertically connected to the spring 10, and the other end of the spring 10 is connected to the inner wall of the hole 4. During use, the elasticity of the spring 10 itself can effectively ensure the tightness of the limiting rod 8 when it is inserted into the limiting groove inside the well seat 1.

[0024] Furthermore, refer to Figure 3 and Figure 5 It can be seen that the sides of the L-shaped plate 5 are respectively connected to the mating blocks 13, and the end of the reinforcing rod 6 is provided with a connecting groove that matches the mating blocks 13. The side of the reinforcing rod 6 is connected to the mating blocks 13 by bolts. The cross-sectional area of ​​the connecting groove and the mating blocks 13 is smaller than the cross-sectional area of ​​the reinforcing rod 6, so as to meet the limiting requirements of the mating blocks 13 being inserted into the connecting groove at the end of the reinforcing rod 6. At the same time, with the bolts, it is convenient for the staff to replace the damaged reinforcing rod 6 during the maintenance process.

[0025] Furthermore, refer to Figure 3 It can be seen that the outer wall of the reinforcing rod 6 is symmetrically glued with rubber plates 14, and the outer wall of the rubber plates 14 is in contact with the inner wall of the U-shaped frame 7. The rubber plates 14 glued to the outer wall of the reinforcing rod 6 can increase the resistance of the reinforcing rod 6 when it is inserted into the U-shaped frame 7. Therefore, when the workers pull the reinforcing rod 6 out of the limiting groove of the well cover body 2 and the support ring 3 to release the reinforcement of the well seat 1, it can effectively prevent the reinforcing rod 6 from easily sliding when the workers rotate the well seat 1 later.

[0026] Furthermore, refer to Figure 4 and Figure 5 It can be seen that a connecting sleeve 11 is inserted inside the hole 4, and the outer surface of the connecting sleeve 11 is provided with external threads. The inner wall of the hole 4 is provided with internal threads that are compatible with the connecting sleeve 11. When the reinforcing rod 6 is inserted into the limiting groove inside the well cover body 2 and the ring 3, there will be a certain gap between the L-shaped plate 5 and the inner wall of the hole 4, which can meet the subsequent threaded connection requirements of the hole 4 and the connecting sleeve 11. With the setting of the spring 10, it is easy to cover and protect the L-shaped plates 5 set inside the hole 4.

[0027] Furthermore, refer to Figure 2 and Figure 5 It can be seen that a slot 12 is provided at the center of the connecting sleeve 11, and the slot 12 is set as a long strip structure. The inner diameter of the slot 12 is larger than the outer diameter of an adult maintenance worker's finger, so that the worker can easily insert his finger into the slot 12 to drive the connecting sleeve 11 to rotate quickly and complete the disassembly and assembly of the connecting sleeve 11.

[0028] Working principle: When using this utility model, the worker can first install the manhole cover 2 at a suitable location on the road. After installation, the worker can pull the connecting plate 9 vertically in sequence, thereby causing the connecting plate 9 connected to its bottom to be lifted simultaneously. Then, the worker can push the L-shaped plate 5 horizontally, causing the reinforcing rod 6 to move simultaneously under force. The end of the reinforcing rod 6 away from the L-shaped plate 5 can be inserted into the insertion groove opened inside the manhole cover 2 and the support ring 3. After insertion, the position of the limiting rod 8 corresponds to the position of the limiting groove opened inside the manhole seat 1. At this point, the operator can stop pulling the connecting plate 9, so that the limiting rod 8 can be embedded into the limiting groove inside the well base 1, thereby limiting the reinforcing rod 6 inserted after the insertion groove. After the limiting work of each set of reinforcing rods 6 is completed in sequence, the operator can insert the connecting sleeve 11 into the hole 4, and then rotate the connecting sleeve 11 to cover the opening of the hole 4. After the covering is completed, the connecting sleeve 11 is horizontal above the well base 1 to ensure the normal use of the device. The above is the complete working principle of this utility model.

As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.
