Embodiment Construction
[0014] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0015] as attached figure 1 .2 shows a manhole cover liner with thermal insulation performance, including the liner body, the surface of the liner body is round, and it is aluminum plate layer 6, cotton fiber layer 7 and steel plate layer 8 from bottom to top, The aluminum plate layer 6, the cotton fiber layer 7 and the steel plate layer 8 are fixedly connected by bolts evenly distributed on the surface of the liner body. The surface of the liner body has four strip-shaped grooves 2 evenly distributed in the radial direction. Extending outwards is a hole of equal width. Double springs 3 and buckle blocks 4 are installed at the bottom of the bar-shaped groove ...

The invention relates to a manhole cover liner plate with the heat preservation performance. A liner plate body sequentially comprises an aluminum sheet layer, a cotton fiber layer and a steel plate layer from bottom to top, strip-shaped grooves uniformly distributed in the radial direction are formed in the surface of the liner plate body, and one ends of the strip-shaped grooves extend outwards to form equal-width holes. Double springs and a buckling block are installed on the bottom of each strip-shaped groove. The double springs are fixedly connected with one ends of the buckling blocks. Protruding blocks which are 2-4 cm high are arranged at the connection ends of the buckling blocks and the double springs. By arranging the aluminum sheet layer, the cotton fiber layer and the steel plate layer, the manhole cover liner plate is good in heat preservation performance, users can compress the springs by pressing the protruding blocks, and therefore the buckling blocks can enter the strip-shaped grooves completely. After the equal-width holes of the linear plate and installation holes in a manhole cover correspond, users can loosen the protruding blocks so that the linear plate can be installed on the manhole cover. According to the structure, stable installation of the linear plate is easy, the service life of the manhole cover can be prolonged, and the manhole cover liner plate is suitable for popularization and application.
Description
technical field [0001] The invention relates to a manhole cover liner with thermal insulation performance. Background technique [0002] The function of the liner is to protect the lined structure from direct internal or external impact and friction. Different forms of liner can be used to adjust the motion state of the lined structure, thereby prolonging the service life of the lined structure. [0003] Generally, manhole covers with special functions need liners, such as manhole covers with thermal insulation function, impact-resistant manhole covers, pressure-resistant manhole covers or manhole covers with antibacterial and sterilizing properties, etc., these The liner of the manhole cover with special performance needs special design to make the manhole cover achieve special performance. If the design is not in place, the manhole cover is easy to wear seriously or seriously affects the product quality inside the manhole cover, and the liner needs to be maintained or rep...
