All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
As shown in figures 1 and 2, the utility model comprises a sealing cover body 5, a sealing gasket 4, a positioning screw hole 3 and a locking bolt 1, wherein the sealing cover body 5 is formed by a plastic die in an integrated mode and is covered and buckled on an anchorage device 6, the utility model also comprises a pressure lever 1 and an ejector rod 8, a first positioning hole and a second positioning hole and a pressing screw hole are respectively arranged on the pressure lever 1, the first positioning hole and the second positioning hole are respectively arranged at two ends and respectively correspond to the positioning screw hole 3, the pressing screw hole is arranged in the middle of the pressure lever 8 and is used for being matched with the ejector rod 8, the ejector rod 8 is a T-shaped screw rod, and the bottom of the T-shaped screw rod is arranged in a contact way with the sealing cover body 5 from top to bottom.
According to the utility model, the sealing cover body is replaced on the existing structure, and the arrangement of the ejector rod 8 and the compression bar 1 is combined, so that the existing slurry leakage position can be quickly replaced, the existing anchor backing plate and the positioning screw hole on the anchor backing plate do not need to be replaced, and the replaced leakage-proof effect can be realized.
A groove 9 is formed in the circumferential end face, in contact with the anchorage device, of the sealing cover body, and a second sealing washer is arranged in the groove 9. The pressing screw hole is an M20 bolt hole. Through the arrangement of the groove 9 and the second sealing gasket, the existing sealing gaskets are matched
The first sealing washer pad 4 to make sealed cowling body 5 and ground tackle 6, sealed the setting between sealed cowling body 5 and the anchor backing plate 2 army, thereby make the sealing performance of whole device better.
The sealing cover further comprises a top plate, and the top plate is arranged between the ejector rod 8 and the sealing cover body 5. The size of the top plate is consistent with that of the top end face of the sealing cover body. Through setting up the roof, when can increaseing the ejector pin extrusion, the terminal surface of sealed cowling body 5 accepts the area, makes its atress more even, avoids appearing damaging.
In this application the depression bar for portable fender version, wholly adopt steel structure processing to form. During the in-service use, the through-hole of portable fender version both sides also can be for the bolt hole of under shed formula design, need tear two fixing bolt completely open down when having avoided that can be fine to alternate just can install, has also avoided fixing bolt often to dismantle the wearing and tearing that bring when having improved the installation rate to fixing bolt's life has been prolonged. The M20 bolt hole reserved in the middle can still adjust the compactness of the grouting cover after the grouting cover is installed on the fixing bolt.
The closed grouting cover is integrally processed by engineering plastic polyamide materials, is solid and durable, and is additionally provided with a section of sealed rubber gasket at the opening, so that the abrasion can be reduced, and the compaction can be better realized, thereby ensuring the sealing property and the pressure maintaining property of grouting
In practical use, aiming at a slurry leakage position, the original sealing cover body is firstly detached, and then the M12 bolt is screwed into two symmetrical positioning holes on the anchor backing plate. Then the grouting cover body is buckled on the anchorage device. And clamping the open slot of the pressure plate on the M12 bolt, screwing the M20 bolt in the middle of the pressure plate, and propping against the cover body to tightly compact the cover body and the anchorage device.
The utility model discloses vacuum mud jacking sealed cowling beneficial effect has following benefit with original vacuum mud jacking sealed cowling contrast:
1. the weight is light. The original vacuum grouting cover is processed by adopting a seamless steel pipe and round steel, and the improved grouting cover is processed by adopting an engineering plastic polyamide material. Taking a 9-hole grouting cover as an example, the weight of the single grouting cover before improvement is 7 kilograms, and the weight of the grouting cover after improvement is 3.35 kilograms, so that the labor intensity of workers is greatly reduced.
2. The installation is convenient. The bolt that original vacuum mud jacking sealed cowling and anchor backing plate are connected does the location concurrently and compresses tightly dual function, because anchor backing plate processes the factor such as damage to anchor backing plate locating screw hole in the difference of meticulous degree and the work progress, the effective thread length in anchor backing plate locating screw hole can be different. During construction, the bolt is always screwed still, and the vacuum mud jacking sealing cover is not tightly compacted with the anchorage device, so that mud leakage is caused. At the moment, the bolt needs to be dismounted, the gasket needs to be additionally arranged, and the depth of screwing in the positioning hole is adjusted again, so that slurry is wasted, and the working time is prolonged. The improved vacuum mud jacking sealing cover changes the pressing mode, and the bolt connected with the anchor backing plate only plays a positioning role and does not play a pressing role, so that the influence of different depths of screw holes of the anchor backing plate on the pressing degree is avoided.
3. Saving cost and simple processing. The original vacuum mud jacking sealing cover needs to be processed through a plurality of procedures such as blanking, boring, grooving, drilling and welding, and the processing period is long. The improved vacuum mud jacking sealing cover can be produced in batch by one-step casting through a plastic mould, so that the processing period is greatly shortened, and the cost is saved.
