Description

A kind of hole cap assemblies of manhole

Technical field

The utility model relates to a kind of hole cap assemblies of manhole.

Background technique

For hand hole as the manhole reduced, installing is to install, dismantle, clean and repair apparatus interior arrangement.It is answered For many aspects, for example paper pulp pipe is due to the particularity of paper pulp fiber, it is easy to block in elbow, therefore generally can be in paper The elbow setting hand hole of slurry pipe is in order to cleaning and dredge blockage；If purchased by client BOM standard hand hole component difficulty, the period It is long, price.In addition, (manhole switch block, hand hole switch block are even for current hand hole component or port lid switch block Size is less than the port lid switch block of hand hole) it is all a hole with a hole cap assemblies, adaptability is not high.

Utility model content

The purpose of this utility model is that overcoming defect existing in the prior art, a kind of port lid group of manhole is provided Part, excellent in design, process-cycle be short, good economy performance and adaptability are high.

To achieve the above object, the technical solution of the utility model is to design a kind of hole cap assemblies of manhole, including hole Core, is set with port lid outside Kong Xin, and hole is covered equipped with boss, at least provided with one for install the opening of hook on boss, opening and Grab cooperation on hook, the middle part rotation of hook are equipped with rotary body, and rotary body is connected by adjusting stud with hole core.General hole Core side surface is the disc of cylindrical body, but its side of hole core when encountering rectangular manhole then in the utility model is shown to be four squares Shape face, and the outer surface (lateral surface) of port lid is still the disc (or saying curved surface) of cylindrical body, because the utility model is by turning The dynamic stud that adjusts realizes the movement for opening, closing (or fastening) hook and Kong Xin, so the outer surface of port lid need to be cylindrical body Disc, and inner wall can then make corresponding change according to the shape of Kong Xin；Opening can along the radial direction of hook its step surface of limited step It, can also be not through hook limited step to run through hook limited step (i.e. exposed hole core segment)；Stud is adjusted by rotation It realizes to change the spacing of Kong Xin and hook and adjusts the elastic of entire port lid switch block, after unscrewing, pass through rotational hook Certain angle, which to link up with grab below and turns to opening and can then take out hole core and hook, (and leaves port lid And manhole), the work that manpower or tool are overhauled or dredged or cleaned at this moment is protruded into again.

Further technical solution is that port lid includes opposite both ends, and one end is adapted with maintenance hole shape, the other end Equipped with the hook limited step that cylinder is step-like, links up with limited step and be equipped at least two openings, opening is along hook limiting stand The rotation axis direction of rank is detached from hook limited step for linking up with through hook limited step, opening, blocks on opening and hook Shape, the size of hook are adapted, and the size of opening is less than the outer diameter of hook limited step；It is equipped in the middle part of port lid and runs through both ends Through hole, providing holes core at through hole, Kong Xin is fixedly connected with port lid, and sealing ring is arranged in the junction of Kong Xin and port lid.

Further technical solution is that hook is connected by adjusting stud with hole core, adjusts stud and is threadedly coupled with hole core； The middle part rotation of hook is equipped with rotary body, and it is upper end, the rotation axis of rotary body that hole, which covers and is equipped with one end of hook limited step, For up and down direction, the middle part of hook is equipped with upper and lower perforative circular hole be adapted to rotary body, the lower part of rotary body be located at circular hole it is interior, Top is stretched out outside circular hole, and the lower end of rotary body is flushed with the lower end of circular hole, and the part fixation that rotary body stretches out outside circular hole is arranged one A sheath with cylinder step, the lower end of rotary body are also that cylinder is step-like, the cylinder step of sheath and the cylinder table of rotary body Rank is used for the limit of rotary body；Stud connection is adjusted on rotary body.It is just able to rotate adjusting stud by rotating rotary body in this way, To realize the movement for opening, closing (or fastening) hook and Kong Xin.

Further technical solution is to adjust stud to be threaded on rotary body, and the lower central position of rotary body is set There is the threaded hole being adapted to adjusting stud, threaded hole is blind hole；The upper and lower ends for adjusting stud are equipped with screw thread, adjust stud Upper end is threadedly coupled with rotary body, and the lower end for adjusting stud is threadedly coupled with hole core.When rotating rotary body in this way, spiral shell is adjusted before this Column is moved up in a rotating body, until adjust stud arrive to after the roof of blind hole continue to rotate rotary body then Kong Xin relative to adjusting spiral shell Column is moved down to complete the process of fastening.

Further technical solution is to adjust stud to be fixedly connected on rotary body, and the lower central position of rotary body is set There is the connecting hole being adapted to adjusting stud, connecting hole is blind hole or perforation；The lower end for adjusting stud is equipped with screw thread, adjusts stud Lower end is threadedly coupled with hole core.When rotating rotary body in this way, adjusts stud and and then rotate, due to adjusting the screw thread of stud and Kong Xin Connection type moves up or down Kong Xin, the process completing fastening or unscrewing；The shape of hook is generally in approximate channel steel Shape, but its thickness is less than the outer diameter of hook limited step, therefore two openings are essentially square aperture, it is vertical by adjusting hook The height hook of different height notch (replacement) of notch adapts to the manhole of different depth on section inner wall.

Further technical solution is that the part that rotary body stretches out outside circular hole is equipped with handle and is inserted into hole, and handle passes through hand Handle insertion hole is fixedly connected with rotary body, is corresponded at the position in handle insertion hole on sheath and is equipped with handle across hole；It is described to open Mouth set there are two, positioned at hook its step surface of limited step it is same diametrically.

Further technical solution is that port lid switch block is hand hole switch block or manhole switch block.It even can be with It is the port lid switch block that size is less than hand hole.

Advantages and beneficial effects of the utility model lie in that excellent in design, process-cycle be short, good economy performance；Pass through replacement Rotary body or replacement hook can adapt to same aperture but the different hand hole of hole depth, and adaptability increases, design concept is ingenious.Port lid Outer surface need to be cylindrical body disc, and inner wall can then make corresponding change according to the shape of Kong Xin；Opening is along hook limit The radial direction of its step surface of step can be through hook limited step (i.e. exposed hole core segment), can also be not through hook limiting stand Rank, flexible design are changeable.
