[0001] The present application relates to the field of anti-settling manhole covers and processing devices thereof, in particular to an anti-settling manhole cover and a processing device thereof. BACKGROUND

[0002] In urban construction, there are many underground pipelines, such as sewer, underground gas pipeline, water pipeline, power pipeline, communication pipeline, and national defense pipeline. These pipelines need an outlet to the ground every certain distance, and the section from the pipeline to the ground is called a manhole. The manhole is usually flush with the ground, so a cover is needed to cover the manhole. Manhole covers are very common in people's lives and are widely used.

[0003] There are many problems in the long-term use process that need to be improved and solved:

[0004] 1. Since the manhole cover is mostly fitted or inlaid into the road surface, the overall support and load of the manhole cover rely on the road surface around the manhole cover, so that the road surface around the manhole cover is subjected to the pressure of vehicles for a long time, the internal structure strength is reduced, and the manhole cover gradually sinks, which causes the problem that the manhole cover needs to be frequently maintained and repaired during use;

[0005] 2. Since the manhole cover is not provided with an anti-theft component, the manhole cover is easily lost during use, which can easily cause a series of safety accidents and endanger the safety of people traveling;

[0043] When the cover 5 is installed, the positioning sleeve 1 and the load-bearing block 2 are fixed as a whole inside the foundation groove, and the extrusion plate 4 is tightly squeezed and fitted with the inner wall of the foundation groove. At this time, the cover 5 is sleeved on the inner wall of the positioning sleeve 1, so that the load-bearing block 2 can be positioned and supported on the cover 5, thereby making the load-bearing block 2 able to be fixed inside the positioning sleeve 1. When the cover 5 is rolled, the pressure can be transmitted to the inside of the pushing column 3 through the load-bearing block 2, and then to the inner wall of the foundation groove through the extrusion plate 4, thereby achieving the pressure deflection effect, prompting the cover 5 to perform a single compaction on the foundation when it is rolled once, thereby avoiding the problem that the road surface foundation becomes soft when rolled for a long time and causes the cover to slowly settle, thereby greatly improving the anti-settling effect of the cover.

[0044] There are two lifting openings 6, and the two lifting openings 6 are symmetrically distributed with the positioning sleeve 1 as the symmetry axis; by setting the lifting openings 6, when the manhole cover needs to be opened for maintenance, the manhole cover locking component is opened and the crowbar tool is inserted into the lifting opening 6 for lifting, so that the cover body 5 can be taken out from the inside of the positioning sleeve 1, thereby achieving the opening effect of the inside of the positioning sleeve 1, which brings convenience to the opening and maintenance of the manhole cover.

[0046] The stabilizing mechanism 16 includes a positioning seat 161, which is fixedly connected to the bottom of the inner cavity of the positioning sleeve 1, and the top of the positioning seat 161 is movably sleeved with a No. 1 sliding ball 162; by setting the stabilizing mechanism 16, when the cover body 5 squeezes the push column 3 through the load-bearing block 2, the positioning seat 161 is able to support the horizontally moving load-bearing block 2 through the No. 1 sliding ball 162, thereby avoiding the problem of close friction between the load-bearing block 2 and the positioning sleeve 1 when the push column 3 moves horizontally, thereby reducing the wear of the push column 3 when moving, that is, improving the service life of the manhole cover.

[0047] One end of the bolt 19 is threadedly sleeved inside the positioning hole 20, and the number of bolts 19 is four; by setting the bolt 19, when the cover body 5 is crushed for a long time and sinks a short distance and needs maintenance, the cover body 5 is removed. At this time, the bolt 19 is rotated so that the bolt 19 can be removed from the inside of the positioning hole 20, so that the pushing column 3 can be extended from the inside of the storage sleeve 18, thereby achieving the effect of adjusting the length of the pushing column 3, that is, achieving the effect of adjusting the position of the load-bearing block 2, which greatly facilitates the maintenance of the manhole cover.

[0048] The reinforcing mechanism 17 includes a mounting base 171, which is movably sleeved on the bottom of the positioning sleeve 1, and a blocking sleeve 172 is fixedly sleeved inside the mounting base 171. A reinforcing steel mesh 173 is movably sleeved inside the mounting base 171. There are four reinforcing steel meshes 173, and the four reinforcing steel meshes 173 are evenly distributed inside the mounting base 171 around the positioning sleeve 1. By setting up the reinforcing mechanism 17, when the manhole cover is installed and fixed, the reinforcing steel mesh 173 is sleeved on the inside of the mounting base 171. At this time, high-strength concrete is poured into the inside of the mounting base 171, so that the reinforcing steel mesh 173 and the concrete can form a limiting foundation to block and limit the extrusion plate 4, thereby greatly improving the compressive strength of the ground around the manhole cover, that is, greatly improving the compressive strength of the manhole cover when in use, and thus greatly improving the service life of the manhole cover.

The limit sleeve 151 is fixedly connected to the bottom of the support platform 8. The bottom of the inner cavity of the limit sleeve 151 is movably sleeved with a No. 2 sliding ball 152. The inner movably sleeve of the limit sleeve 151 is connected to a receiving water tank 153. A discharge port 154 is provided on the top of the support platform 8. By arranging the limit column 9, when the height of the lifting platform 11 is adjusted, the limit column 9 is able to limit the lifting platform 11 moving up and down, that is, to limit the milling mechanism 12, thereby avoiding the problem of position tilt and offset when the milling mechanism 12 is lifted or lowered.

[0050] The milling mechanism 12 includes a No. 1 electric slide rail 121, which is fixedly mounted on the bottom of the lifting platform 11. The bottom of the No. 1 electric slide rail 121 is movably connected to a No. 1 sliding sleeve 122. The bottom of the No. 1 sliding sleeve 122 is fixedly connected to a No. 2 electric slide rail 123. The bottom of the No. 2 electric slide rail 123 is movably connected to a No. 2 sliding sleeve 124. The bottom of the No. 2 sliding sleeve 124 is fixedly mounted with a drive motor 125. A milling cutter head 126 is fixedly mounted on the output shaft of the drive motor 125. By setting the milling mechanism 12, when the load-bearing block 2 needs to be milled, the load-bearing block 2 is moved. It is fixed on the top of the support platform 8. At this time, the No. 1 sliding sleeve 122, the No. 2 sliding sleeve 124 and the drive motor 125 are started, so that the drive motor 125 can drive the milling cutter head 126 to rotate rapidly. At this time, the No. 1 sliding sleeve 122 and the No. 2 sliding sleeve 124 can drive the rotating milling cutter head 126 to move in a plane, so that the milling cutter head 126 can perform synchronous milling processing on the load-bearing block 2, thereby avoiding the problem of multiple disassembly and fixation of the load-bearing block 2 during the separate milling process, thereby bringing convenience to the processing of the load-bearing block 2, that is, bringing convenience to the machining of the manhole cover.

[0051] The lifting mechanism 13 includes a lifting motor 131, which is fixedly installed at the bottom of the positioning platform 10. A threaded column 132 is fixedly connected to the output shaft of the lifting motor 131, and the threaded column 132 is threadedly sleeved on the inside of the lifting platform 11; by setting the lifting mechanism 13, when the load-bearing block 2 is milling, the lifting motor 131 is started, so that the lifting motor 131 can drive the lifting platform 11 up and down through the threaded column 132, that is, drive the milling mechanism 12 up and down, thereby facilitating the adjustment of the milling depth of the load-bearing block 2, and further facilitating the processing of different types of manhole covers.

[0052] The working principle of the anti-sinking manhole cover and the processing device thereof provided by the present invention is as follows:

[0053] First, when installing the manhole cover, the positioning sleeve 1 and the load-bearing block 2 are fixed as a whole inside the foundation groove. At this time, the extrusion plate 4 is tightly squeezed and fitted with the inner wall of the foundation groove. At this time, the cover body 5 is sleeved inside the positioning sleeve 1, so that the load-bearing block 2 can position and support the cover body 5, so that the load-bearing block 2 can be limited and fixed inside the positioning sleeve 1, so that when the cover body 5 is rolled, the pressure can be transmitted to the inside of the pushing column 3 through the load-bearing block 2, and then transmitted to the inner wall of the foundation groove through the extrusion plate 4, thereby achieving a pressure diversion effect, prompting the cover body 5 to compact the foundation once when it is rolled, so as to avoid the problem of the manhole cover slowly settling due to the softening of the road foundation during long-term rolling, thereby greatly improving the anti-settling effect of the manhole cover. When the lid 5 needs to be opened for maintenance, the lid locking component is opened and the crowbar tool is inserted into the lifting port 6 to lift it, so that the lid 5 can be taken out from the inside of the positioning sleeve 1, thereby achieving the opening effect of the positioning sleeve 1, which is convenient for opening and repairing the lid. When the lid 5 is installed, the mechanical lock 71 drives the rotating clamping post 72 to rotate, so that one end of the rotating clamping post 72 can be stuck and sleeved in the inside of the clamping groove 73, so that the rotating clamping post 72 can be stuck and fixed in the inside of the positioning sleeve 1 through the clamping groove 73, thereby achieving the anti-theft effect of the lid 5, thereby improving the safety of the lid when used for a long time. When the lid 5 squeezes the pushing post 3 through the bearing block 2, the positioning seat 161 can pass through the first The sliding ball 162 supports the horizontally moving load-bearing block 2, thereby avoiding the problem of close friction between the load-bearing block 2 and the positioning sleeve 1 when the push column 3 moves horizontally, thereby reducing the wear of the push column 3 when moving, that is, improving the service life of the manhole cover. When the cover body 5 is crushed for a long time and sinks for a short distance and needs maintenance, the cover body 5 is removed. At this time, the bolt 19 is rotated so that the bolt 19 can be removed from the inside of the positioning hole 20, so that the push column 3 can be extended from the inside of the storage sleeve 18, thereby achieving the effect of adjusting the length of the push column 3, that is, achieving the effect of adjusting the position of the load-bearing block 2, which brings great convenience to the maintenance of the manhole cover. When installing and fixing the manhole cover, the reinforcing steel mesh 173 is sleeved on the inside of the mounting base 171. At this time, high-strength concrete is poured into the interior of the mounting base 171, so that the reinforcing steel mesh 173 and the concrete can form a limiting foundation to block and limit the extrusion plate 4, thereby greatly improving the compressive strength of the ground around the manhole cover, that is, greatly improving the compressive strength of the manhole cover when in use, and thus greatly improving the service life of the manhole cover. When the height of the lifting platform 11 is adjusted, the limiting column 9 can limit the lifting platform 11 moving up and down, that is, limit the milling mechanism 12, so as to avoid the problem of position tilt and offset when the milling mechanism 12 is lifted and lowered. When the load-bearing block 2 needs to be milled, the load-bearing block 2 is fixed to the top of the support platform 8, and the No. 1 sliding sleeve 122, the No. 2 sliding sleeve 124 and the drive motor 125 are started at this time.The driving motor 125 drives the milling cutter head 126 to rotate rapidly, and the first sliding sleeve 122 and the second sliding sleeve 124 drive the rotating milling cutter head 126 to move in a plane, so that the milling cutter head 126 can mill and process the weight block 2 synchronously, thereby avoiding the problem that the weight block 2 needs to be disassembled and fixed for multiple times when the milling process is separated, thereby facilitating the processing of the weight block 2, that is, facilitating the machining of the well lid. When the weight block 2 is milled, the lifting motor 131 is started, so that the lifting motor 131 drives the lifting platform 11 to move up and down through the threaded column 132, that is, drives the milling mechanism 12 to move up and down, thereby facilitating the milling depth adjustment of the weight block 2, and further facilitating the processing of different types of well lids.
