Abstract

The invention relates to an embedded type well tool. A well ring of the well tool is fixed on a well ring seat by a bolt and a nut, and a well cover is fixed on a step of the well ring by a bolt, wherein the step of the well ring passes through a bolt, the upper part of the bolt and the side face of the well cover are provided with cross holes; a pin is inserted in the cross holes, and one end of the pin is welded and smoothed and parallel to the side face of the well cover; the tail end of the bolt is embedded in a shallow groove of the well cover to form an embedding and locking knot so as to ensure that the well cover is not easy to steal and guarantee that pedestrians and vehicles cannot fall into the well to cause accidents. In addition, during construction, the surface of the well cover is consistent with the gradient of a road surface as much as possible so as to ensure that the vehicles can steadily run without bumping and vibrating and reduce the generation of noise.

Description

Embedded type well tool

Technical field

The present invention relates to a kind of embedded type well tool, it adopts and inlays the locking fixed structure, is a kind of well tool of safe antitheft.

Background technology

The inspection hole hand-hole well tool of present underground pipeline (comprising cable, natural gas line and sewer pipe), because the defective of its structure or the carelessness of construction, well lid is concordant inadequately with the road surface, after using a period of time, cracked or the depression of periphery takes place and becomes round pool in regular meeting, causes the well lid bad sealing and makes rainwater or dirt deposition and flow in the well; Usually jolt when vehicle travels and produce noise.In addition, well lid regular meeting is but failed in time to fill by illegal people's theft, has increased the danger that pedestrian or vehicle are absorbed in accident in the well.

In 04 year, I once applied for patent at situation, and the patent No. is 20040077660.1, once was subjected to the favorable comment of municipal sector, according to the experience of practice, will do further to improve to the well tool.

Summary of the invention

The objective of the invention is to provide a kind of embedded type well tool, and it can overcome above-mentioned shortcoming, its novel structure, adopt pin to be welded in nut, nut passes the step of walling crib again, this inserted structure, make well lid be difficult for being stolen by the ruffian, played antitheft effect.

Embedded type well tool is achieved in that

Walling crib 1 has 4 holes 10 and passes hole 10 with bolt 3 and is fixed on above the walling crib seat 7, well lid 2 has 4 holes 14, the bolt 3 of packing in the hole, bolt 3 cooperates with the screwed hole of the step 16 of walling crib 1, well lid 2 bottom reinforcements 18 have shallow slot 19, walling crib 1 has step 15 and step 16, and bolt 17 passes the hole of step 15 and step 16 from bottom to top, and the tail end of bolt is entrenched in the shallow slot 19.Walling crib 1 has 4 holes 10, penetrates bolt 5, nut 6 and fills up 24 fastening in walling crib seat 7.There are decorative pattern 18 and 2 slotted holes 11 of U-shaped fin 9 and hexagon combination on the surface of well lid 2, and well lid 2 has groined type fin 12.Middle part solid welding one pad 23 of bolt 3.

Embedded type well tool is compared with existing well tool, has following advantage:

1. step is arranged at walling crib bottom, and bolt is bottom-up passing from the hole of step, and the tail end of bolt embeds in the wire casing of well lid bottom, and bolt is laterally porose, inserts pin and solid welding in the hole, walling crib and well lid firmly is integral and not quick detachable.

2. plug-in mounting bolt and be fixed in the step of walling crib and be combined into one in four of well lid holes, connecting bolt is welded with pad, does not make bolt quick detachable and play antitheft effect.

3. the well lid surface can adapt with the gradient on road surface, and driving can not jolted to vibrate also and can be reduced noise.

4. well lid can be cast with the title of manhole and numbering and be easy to management.

The specific embodiment

By Fig. 1, the well tool is made up of walling crib 1 and well lid 2 and bolt 3 and nut 4, and walling crib 1 usefulness bolt 5 and nut 6 are fixed on above the concrete well ring support 7.

By Fig. 2, there are the decorative pattern 8 of six shape combinations and the fin of U-shaped in well lid 2 surfaces, fin is title and the numbering in order to cast the well tool also, for example cable shaft, sewer and gas flue well etc., uniform four slotted holes 10 in walling crib 1 surface, well lid 2 has slotted hole 11 (the expression slotted hole is the setting shape among the figure, in fact also can be arranged to diacytic type) in addition, and this hole is used for the instrument dismounting or well lid 2 is installed.

By Fig. 3, well lid 2 bottom surfaces have groined type fin 12 to link to each other with the annular fin 13 of periphery, and well lid 2 has 4 holes 14 and pictorial trademark 22.

By Fig. 4, step 15 and 16 are arranged at walling crib 1 bottom, bolt 17 passes from the hole of step 15 and 16 from lower to upper, the tail end of bolt is entrenched in the shallow slot 19 of reinforcement 18 of well lid 2 bottoms, plug-in mounting one pin 21 in the upper lateral of bolt 17 porose 20 and the hole, after the pin solid welding, the left end of pin polished and concordant with the side of well lid.

By Fig. 7, the reinforcement 18 of well lid 2 has shallow slot 19.

By Fig. 8, walling crib 1 has 4 holes 10, passes bolt 5 in the hole, and is fastening with nut 6 and pad 24.

By Fig. 9, well lid 2 has plug-in mounting bolt 3 in 4 holes 14 and the hole, and the middle part of bolt 3 is welded with a pad 23, and bolt 3 can not be taken out from the well lid hole, and the tail end of bolt 3 is twisted (not shown) in the step 16 of walling crib 1 admittedly.

During use, as needs dismounting well lid 2, can turn 4 bolts, make its afterbody break away from the screwed hole of the step 16 of walling crib 1, and then make bolt 17 upwards liftings, make the hexahedron of bolt 17 near the bottom surface of step 16, insert two holes of well lid 2 with special tool, rotating well cover 2 just can take off well lid 2, when mounted, can store less amount of lubrication oil in the screwed hole of step 16 and makes the unlikely corrosion of bolt.
