Description

Technical Field

[0001] This utility model relates to the field of road construction and maintenance technology, specifically to a manhole cover with tactile paving that is easy to install and remove. Background Technology

[0002] The field of road construction and maintenance technology encompasses the professional knowledge, skills, and methods involved in the construction, renovation, daily maintenance, and repair of various types of roads. It employs appropriate repair techniques and maintenance measures, such as crack sealing, pothole repair, and pavement recycling, to maintain the good performance and structural integrity of roads, extend their service life, and ensure safe and smooth road traffic.

[0003] Currently, easy-to-install manhole covers are used in various functional facilities for manholes in urban roads, public places, etc. The upper surface of the manhole cover is equipped with tactile paving. This tactile paving design can provide clear guidance for visually impaired people to walk, allowing them to perceive the texture of the tactile paving by the soles of their feet, thereby successfully identifying the direction and path of travel, ensuring the safety and convenience of visually impaired people during their travels.

[0004] However, the applicant believes that the shortcomings are: 1. When the equipment is used for a long time, the tactile paving may wear down or become flat, which requires the entire equipment to be disassembled and replaced, thus reducing the service life of the equipment; 2. Most equipment is difficult to disassemble and assemble, and takes a long time, which to some extent reduces the convenience and work efficiency of the equipment.

[0005] To address this issue, we propose a manhole cover with tactile paving for easy installation and removal. Utility Model Content

[0006] The purpose of this utility model is to provide a manhole cover with tactile paving that is easy to install and remove, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a manhole cover with tactile paving for easy loading and unloading, comprising a manhole cover body and a base.

[0008] The top two ends of the manhole cover body are fixed with friction textures, and multiple sets of square grooves are opened inside the friction textures. The square grooves are filled with rubber. A placement plate is slidably inserted at one end of the friction texture on the top of the manhole cover body. Both ends of the placement plate are threaded and bolted. Guide strips are evenly distributed in a linear array inside the placement plate. A tactile paving body is fixed at the middle of the top of the manhole cover body. Grooves are opened on both sides of the manhole cover body, and knobs are slidably engaged on the surface of the grooves. Rotary rods are slidably inserted on both sides of the manhole cover body, and a spring is fixed at one end of the rotating rod. The spring is slidably inserted inside the manhole cover body.

[0009] Preferably, the height of the friction pattern, guide strip, and tactile paving pattern is greater than the height of the manhole cover. Through the above operation, blind people can more quickly sense the location of the device with their canes when walking.

[0010] Preferably, pull grooves are provided at both ends of the manhole cover body on both sides of the tactile paving body, which allows the equipment to be taken out more easily.

[0011] Preferably, positioning posts are fixed on both ends of the bottom of the manhole cover body, and a limiting plate is provided at the bottom of the inner wall of the base. Circular grooves are opened on both ends of the limiting plate, and the surface of the circular grooves is in contact with the surface of the positioning posts. The upper surface of the limiting plate is in contact with the bottom surface of the manhole cover body. When the lower surface of the manhole cover body is in contact with the surface of the limiting plate, the circular grooves simultaneously contact the surface of the positioning posts, thereby restricting the position of the manhole cover body.

[0012] Preferably, the knob is provided with an anti-slip block on its side. The anti-slip block helps prevent the operator from slipping their hand while using the equipment, thereby improving work efficiency.

[0013] Preferably, the surface of the rotating rod is threadedly connected to the knob, and rotating the knob causes the rotating rod to move inward or outward.

[0014] Preferably, threaded grooves are provided on both sides of the inner wall of the base, and the surface of the threaded grooves is in contact with the surface of the rotating rod. This operation can fix the position of the manhole cover body and the base.

[0015] This utility model provides a manhole cover with tactile paving for easy installation and removal, which has the following features:

[0016] Beneficial effects:

[0017] By using friction textures and rubber in combination, the friction between the equipment and pedestrians or vehicles can be increased, preventing pedestrians from slipping or losing their footing in rainy weather. Then, by moving the placement plate downwards into the inside of the manhole cover body, the position of the placement plate and the manhole cover body is fixed by rotating the bolts. When the guide strip is damaged or worn after long-term use, the placement plate can be replaced, disassembled or installed through the above operation, thereby improving the service life of the equipment.

[0018] By moving the manhole cover body so that its bottom surface fits against the limiting plate surface of the inner wall of the base, and at the same time, the positioning pin fits against the surface of the circular groove, thus restricting the position of the manhole cover body, the knob is then turned, thereby driving the rotating rod to move outward. When the surface of the rotating rod is inserted into the base, the position of the manhole cover body and the base can be fixed. At the same time, with the cooperation of the spring, the rotating rod can be prevented from sliding or moving backward during the use of the equipment, thereby improving the stability of the equipment. The above operation is relatively simple and allows for quick installation and disassembly of the equipment, which improves the convenience and work efficiency of the equipment to a certain extent.

[0026] 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, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This embodiment proposes a manhole cover with tactile paving for easy installation and removal.

[0028] Example 1

[0029] like Figures 1 to 3 As shown, this embodiment proposes a manhole cover with tactile paving that is easy to install and remove, including a manhole cover body 1 and a base 12. Friction patterns 2 are fixed at both ends of the top of the manhole cover body 1, and multiple sets of square grooves are opened inside the friction patterns 2, and the square grooves are filled with rubber 3. A placement plate 4 is slidably inserted at one end of the friction patterns 2 on the top of the manhole cover body 1, and bolts 5 are threaded to both ends of the placement plate 4. Guide strips 6 are evenly distributed in a linear array inside the placement plate 4. A tactile paving body 7 is fixed at the middle position of the top of the manhole cover body 1. The height of the friction patterns 2, guide strips 6 and tactile paving body 7 is greater than the height of the manhole cover body 1.

[0030] In the above embodiment, the friction texture 2 and rubber 3 work together to increase the friction between pedestrians or vehicles when they pass over the device, preventing pedestrians from slipping and falling due to slippery conditions in rainy weather. At the same time, it can protect both ends of the manhole cover body 1 and reduce its wear time. When the placement plate 4 needs to be installed or replaced, it can be moved into the inside of the manhole cover body 1. Then, the positions of the manhole cover body 1 and the placement plate 4 are fixed by rotating the bolts 5. With the cooperation of the guide strip 6, the guide cane can detect the position of the device more quickly, thereby guiding the blind person to continue walking on the upper end of the tactile paving body 7.

[0031] Example 2

[0032] like Figure 4 and Figure 5As shown, based on the same concept as the above embodiment, this embodiment also proposes: grooves are provided on both sides of the manhole cover body 1, and a knob 9 is slidably engaged on the surface of the groove; a rotating rod 10 is slidably inserted on both sides of the manhole cover body 1, and a spring 11 is fixed at one end of the rotating rod 10, and the spring 11 is slidably inserted inside the manhole cover body 1; pull grooves are provided at both ends of the manhole cover body 1 on both sides of the tactile paving body 7; positioning posts 8 are fixed on both ends of the bottom of the manhole cover body 1; a limiting plate is provided at the bottom of the inner wall of the base 12, and a circular groove 13 is provided on both ends of the limiting plate, and the surface of the circular groove 13 is in contact with the surface of the positioning post 8; the upper surface of the limiting plate is in contact with the bottom surface of the manhole cover body 1; an anti-sliding block is provided on the side of the knob 9; the surface of the rotating rod 10 is threadedly connected to the knob 9; threaded grooves are provided on both sides of the inner wall of the base 12, and the surface of the threaded grooves is in contact with the surface of the rotating rod 10.

[0033] In the above embodiment, the groove allows for better rotation of the knob 9, and the spring 11 increases the stability of the rotating rod 10, thereby improving the stability of the manhole cover body 1 and the base 12. Rotating the knob 9 moves the spring 11 inward or outward. When moving outward, it can be fixed to the base 12. When the spring 11 moves inward, the manhole cover body 1 can be disassembled, thus improving the convenience of the equipment. Moving the manhole cover body 1 moves the positioning column 8 downward. When the surface of the positioning column 8 is in contact with the surface of the circular groove 13, the position of the manhole cover body 1 can be restricted, which can increase the speed of equipment installation and thus increase work efficiency.

[0034] Working principle: When using the equipment, first move the base 12 to a suitable position, then install the base 12. Subsequently, move the manhole cover body 1 to make the positioning post 8 fit against the surface of the circular groove 13, thereby restricting the position of the manhole cover body 1. Then turn the knob 9, at which time the rotating rod 10 can move outward and be inserted into the interior of the base 12, thereby fixing the position of the manhole cover body 1 and the base 12. Next, move the placement plate 4 downward into the interior of the manhole cover body 1, and turn the multiple sets of bolts 5 to fix the position of the manhole cover body 1 and the placement plate 4. When the guide cane touches the surface of the guide strip 6, the blind person can be guided to walk on the upper end of the tactile paving body 7 through the guide strip 6. At the same time, the friction texture 2 and the rubber 3 work together to increase the friction at both ends of the equipment and prevent pedestrians from slipping. The above is the complete working principle of this utility model.

[0035] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may change.

[0036] Secondly: The accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0037] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
