A kind of spherical tank internal hydraulic pressure type detection device
Technical field
The present invention relates to a kind of spherical tank internal hydraulic pressure type detection devices, belong to industrial dedicated inspection device technical field.
Background technology
Spherical tank, common a kind of pressure vessel in chemical industry are mainly used to store, conveying liquified oil gas, liquid oxygen, liquid The gaseous steel pressure vessel such as the liquid such as nitrogen or oxygen, nitrogen, is widely used in petroleum refining industry and petrochemical industry.Phase For general storage tank, spherical tank has many advantages, such as that material saving, floor space are small.But spherical tank manufacture simultaneously, welding, group reload request compare Strictly, maintenance task is big, and manufacturing expense is high.
When pressure vessel during manufacture, installation, use it is possible that various errors and abrasion condition, therefore, It is periodically necessary to pressure vessel detection.Traditional spherical tank detection method is that a large amount of foot hand is built inside spherical tank Frame, reviewer climb on scaffold, working at height.Not only time-consuming for this method, but also has certain danger.Cause This, must be noted that the following in checkout procedure:
1. before examining work, the scene of inspection must be according to security system site clearing.As natural gas station cannot open mobile phone, no Can smoke etc..
2. examined spherical tank should be isolated with other equipment, and apparent mark is arranged.
3. the scaffold height built is suitable, layer is away from reasonable, and suitably, channel is unobstructed for the distance between frame plate and weld seam; When examining unfinished, scaffold is not tampered arbitrarily;The scaffold of installation cannot destroy spherical tank surface.
Patent 200920289372.5 describes a kind of spherical tank inspection associated working platform that can move freely.Main body packet Include the regular polygon truss being arranged on spherical tank vertical centre axis, movably autonomous working platform, vertical driving mechanism, Horizontal mobile mechanism, coupling mechanism.Since the detection environment is in combustible and explosive area, there is generation again using electric control system The possibility of spark, to detecting security presence hidden danger;Its main support partial volume is huge simultaneously, is not easy rapid dismounting.It should One workbench can only test in 120 degree of detection range, there is dead angle.
Patent 201020156974.6 describes a kind of rotating bracket for spherical tank inspection.The rack body is that a master is vertical The upper end of column, head tree is hung by a horizontally disposed fixed orifice plate on the manhole of spherical tank top, and the lower end of head tree passes through The support footing of inclination arrangement is against on the ball wall around spherical tank low side manhole around manhole, on the head tree at spherical tank center The one pivoted arm connecting seat that can be rotated horizontally is set, is uniformly spaced on pivoted arm connecting seat and is connected to the double leval jib that spherical tank radially extends The free end of mechanism, four-bar mechanism is installed with Worker carrying basket, and Worker carrying basket passes through liter close to spherical tank wall, the upper end of Worker carrying basket Drop steel wire rope is connected with the connecting seat that thirst of head tree upper end.Due to the additional levels external force of hawser, hanging basket is it is difficult to ensure that balance. The mechanism structure is huge, installation with it is inconvenient for use, while the setting of mechanism is difficult to that operating personnel is made to operate in any direction.
Patent 201410267973.1, provide can in spherical tank on three-dimensional any direction act the manned dress of detection It sets.In the wirerope fixed position of newel and mounting hanger, bearing is housed, facilitates device in the movement in each orientation.With it is above Two patents are compared, and device design is more thorough, but still needs to carry out more installation in spherical tank, influences service efficiency.
Patent 201710358649.4 describes a kind of inside regular inspection hydraulic pressure manned device for spherical tank inspection.Packet The column in spherical tank, hydraulically extensible swing arm and workbench, hydraulic station, vertical post rotating mechanism, swing arm equipped with electric cabinet is included to adjust Mechanism.The device needs the mechanism of hydraulic oil too many.Hydraulic swivel head, hydraulic capstan, hydraulically extensible oil and four are flexible dynamic Arm.
The invention patent advanced optimizes mechanism, reduces hydraulic oil on the basis of patent 201710358649.4 It uses, the flexible shelves of hydraulic levels telescopic arm is set, avoids encountering, damage spherical tank.It solves needs simultaneously and builds and build scaffold Inconvenience.
