Abstract
The utility model relates to a kind of conduit for pile casting of pile foundation engineering joint, solves the problem operation of ZL201220231670.0 scheme existing risk.Structure is by the outer silk braid with open end cap, the plug composition of the interior silk braid with open end cap and tubulose, the upper end outer wall of plug connects power transmission cranse that a cross section is II font and forms one with plug, pass through screw thread, after power transmission cranse and interior silk braid open end cap combine pipe joint, outer silk braid inwall, plug outer wall and the rear closed space formed in order to settle air bag of power transmission cranse inwall combination, gaseous core stretches out from the top of power transmission cranse, the II type sidewall of power transmission cranse stretches into outer silk braid inwall and plays integrated positioning effect, II type side-wall outer side also can bind round O shape cushion rubber simultaneously, joint re-seal is made through extruding away from the termination of end cap side with outer silk braid sidewall.The utility model structure is simple, safe and reliable.
Description
Technical field
The utility model relates to a kind of pile foundation engineering device, particularly a kind of conduit for pile casting of pile foundation engineering joint.
Background technology
Invent for the ZL201220231670.0 conduit utility model after the basis of inventing in patent No. ZL201020238991.4 conduit utility model is improved,
After trial-production input is on probation, find the problem that still there is handling safety when dismantling conduit, during dismounting conduit, the step of safety operation is, after turning on joint screw thread, air bag is exitted in advance, again joint is separated, if operate miss, does not namely make air bag deflation pressure release and directly make pipe joint be separated, then balloon burst, give in operation and bring security risk, for this problem, butt joint structure has done again necessary improvement.
Summary of the invention
The utility model has done necessary improvement to Chinese patent ZL201220231670.0, eliminate middle part airbag cover hoop and bottom to box cupling, power transmission cranse and plug design are integrated, the gaseous core of air bag stretches out from power transmission cranse top, cancel the rubber cushion of bottom, increase O shape cushion rubber, solve the problem operation of former scheme existing risk.
The utility model is realized by following technical scheme:
A kind of conduit for pile casting of pile foundation engineering joint, comprise interior silk braid, outer silk braid, plug, power transmission cranse, O shape cushion rubber and the air bag with gaseous core, interior silk braid, outer silk braid is by sidewall and the end cap composition having centre bore, plug is tubulose, outer wall connection cross section, plug upper end is the power transmission cranse of П font and forms one with plug, outer silk braid sidewall is provided with O shape cushion rubber away between the termination of end cap side and power transmission cranse, outer silk braid inwall, plug outer wall and the rear closed space formed in order to settle air bag of power transmission cranse inwall combination, gaseous core stretches out from the top of power transmission cranse, plug upper end is connected with body, the end cap of outer silk braid is connected with body, interior silk braid, outer silk braid is threaded cooperation.
The utility model structure is simple, safe and reliable, overcomes the defect of patent ZL201220231670.0 completely.
Accompanying drawing explanation
Fig. 1 is that the utility model structure partly cuts open schematic diagram (omission right half part);
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, the utility model comprises interior silk braid 1, outer silk braid 2, plug 3, power transmission cranse 4, O shape cushion rubber 5 and the air bag 6 with gaseous core 7, interior silk braid 1, outer silk braid 2 is by sidewall and the end cap composition having centre bore, plug 3 is tubulose, outer wall connection cross section, plug 3 upper end is the power transmission cranse 4 of П font and forms one with plug 3, outer silk braid 2 sidewall is provided with O shape cushion rubber 5 away between the termination of end cap side and power transmission cranse 4, outer silk braid 2 inwall, plug 3 outer wall and the rear closed space formed in order to settle air bag 6 of power transmission cranse 4 inwall combination, gaseous core 7 stretches out from the top of power transmission cranse 4, plug 3 upper end is connected with body 8, the end cap of outer silk braid 2 is connected with body 9, interior silk braid 1, outer silk braid 2 is threaded cooperation.
Feature of the present utility model:
1, O shape cushion rubber is utilized to coordinate air bag to implement sealing to structure.
2, because air bag pressure forms deboost to inside and outside silk braid, during connecting duct, first must combine and fastening inside and outside silk braid, and then give airbag aeration.
When 3, dismantling conduit, because air bag pressure forms deboost to inside and outside silk braid, strengthen the mill resistance existed between screw thread, screw thread is not easily opened, so after this structure proper property just forces operating personnel first air bag must be discharged air pressure, inside and outside silk braid is just easily opened, and doing so avoids the security risk problem of balloon burst.
The structure that the utility model is mentioned is the one of embodiment, and all principles of air bag that utilizes reach result of use of the present utility model, all in protection domain of the present utility model.
