Description
Technical Field
The invention relates to the technical field of inspection wells, in particular to an anti-falling inspection well.
Background
There are many underground pipes in urban construction, such as sewers, underground gas pipes, water supply pipes, power pipes, communication pipes, defense pipes, etc., which have an outlet to the ground at every other section, the section from the pipe to the ground is called a manhole, which is usually flush with the ground, and therefore a cover is needed to cover the manhole, called a manhole cover. The inspection well cover is usually made of reinforced cement, metal, reinforced plastic and other materials, and the shape of the inspection well cover mainly takes a round shape and a square shape. Along with inspection shaft quantity constantly increases, the potential safety hazard that its brought is also more and more, and the inspection shaft lid is stolen or damaged the back, and the accident that the pedestrian dropped takes place for the inspection shaft that loses the inspection shaft lid often, and the pedestrian will cause the pedestrian in case of dropping in the inspection shaft in, and casualties.
The patent of the Chinese utility model with the granted publication number of CN204475372U discloses an inspection well anti-falling well cover, which comprises a well seat and a cover body matched with the well seat, wherein the inner wall of the well seat is provided with a support frame for supporting the cover body; the well seat is also internally provided with an anti-falling cover, and the edge of the anti-falling cover extends outwards to form more than two clamping strips; grooves corresponding to the clamping strips in number are formed in the supporting frame, and the clamping strips of the anti-falling inner cover can fall into the grooves. After the well lid is lost or damaged, prevent that the lid of falling can prevent that the pedestrian from falling the inspection shaft, improve the security.
The above prior art solutions have the following drawbacks: the inspection well needs to be maintained and overhauled regularly, and an overhaul worker needs to enter the inspection well, so the inspection well can be opened completely only after the anti-falling cover is taken out of the well base, the space in the inspection well is small, the anti-falling cover is rotated and taken out of the inspection well, and the maintenance and the overhaul are inconvenient.
Disclosure of Invention
The invention aims to provide an anti-falling inspection well which can conveniently receive and release an anti-falling baffle and is convenient to maintain and overhaul.
The technical purpose of the invention is realized by the following technical scheme: the utility model provides a prevent weighing down inspection shaft, establishes the well lid on the walling crib including walling crib and the lid that sets up in the walling crib upper end, just is located on the walling crib below is provided with along circumference and is no less than three and prevents weighing down the baffle, prevent weighing down the baffle and rotate and connect on the walling crib, just be located walling crib and prevent weighing down and be provided with on the walling crib and order about and prevent weighing down baffle pivoted drive arrangement between the baffle, drive arrangement includes along vertical direction sliding connection and is being close to the actuating lever that the walling crib was served at.
Through adopting above-mentioned technical scheme, when needs overhaul the inspection shaft, when the maintainer goes down in the inspection shaft, order about the vertical downstream of actuating lever and be used in preventing weighing down the baffle and being close to one of the wall of a well and serve, prevent weighing down the baffle and upwards rotating towards the one end of walling crib seat centre of a circle department this moment, and draw in towards wall of a well one side, each prevents weighing down the baffle and draws in the back in, thereby open the inspection shaft, the maintainer just can get into and examine in the inspection shaft, after its inspection finishes, then will prevent weighing down the baffle and turn over the back down, a plurality of prevent weighing down the baffle will play and prevent weighing down the effect, thereby can receive and release the baffle of preventing weighing.
The invention is further provided with: the anti-falling baffle is close to one of the wall of a well and is provided with a mounting groove for embedding of the driving rod, the inner walls of two sides of the mounting groove are provided with sliding elongated grooves along the length direction of the anti-falling baffle, and one end of the driving rod is provided with a sliding rod penetrating through the sliding elongated grooves.
By adopting the technical scheme, when the driving rod vertically moves downwards, the sliding rod can be abutted against the inner wall of the sliding long groove, so that the end, close to the well wall, of the anti-falling baffle is driven to rotate downwards, the sliding rod can slide in the sliding long groove at the moment, and the anti-falling baffle can be continuously driven to rotate.
The invention is further provided with: when the anti-falling baffle is turned upwards and folded, one end of the anti-falling baffle, which is far away from the well wall, is positioned below the well ring seat, and a groove for embedding the driving rod is formed in the anti-falling baffle.
By adopting the technical scheme, after the driving device drives the anti-falling baffle to rotate, the anti-falling baffle can be gathered below the manhole seat after being turned upwards, and the driving rod is embedded into the groove, so that the anti-falling baffle can not occupy the space in the manhole during maintenance, and a maintainer can conveniently enter the manhole.
The invention is further provided with: drive arrangement is still including setting up on the wall of a well and being located the collar that prevents weighing down the baffle top, seting up on the collar downside and being annular groove of sliding, along vertical direction slide and connect the driving ring at the inslot that slides, the one end setting of actuating lever is in on the driving ring, the collar is located on the curb seat downside, just the internal diameter of collar equals curb seat internal diameter.
By adopting the technical scheme, after the maintainer enters the inspection well, the driving ring vertically moves downwards in the sliding groove, the driving ring can drive each driving rod to simultaneously move downwards, and each anti-falling baffle can be driven to turn upwards together; meanwhile, after the anti-falling baffle is turned downwards at last, one end of the anti-falling baffle close to the well wall drives the driving rod to move upwards, and finally the driving ring is tightly abutted to the bottom of the sliding groove, so that the anti-falling baffle can be limited.
