Description
Technical field
The invention belongs to industrial dedicated inspection device field, particularly relate to the manned equipment of the inner regular inspection of spherical tank.
Background technology
Along with the development of chemical industry, all kinds of pressure-bearing spherical liquid-storage tank are used widely.Use after certain time limit in pressure-bearing spherical liquid-storage tank, need to do periodic inspection to the weld seam of spherical tank inside, in order to make reviewer can arrive each weld seam position in spherical tank, generally need to set up cripple in spherical tank inside, climb for reviewer.The shortcoming of this method is:
(1) build workload large, the cycle is long.Because spherical tank internal capacity is large, building shelf needs thousands of hack levers, frame plate, fastener, is transported to behind scene to enter spherical tank assembling by the manhole of 500mm only and connect again, and overall weight is large, need the many people Gao Qian long work of shutting out just can complete, and in the process of installing easy damaged tank body.
(2) use inconvenience, operating efficiency is low.When tradition scaffold uses, people will ceaselessly move instrument detection position on scaffold, and portable power source line, equipment also will be walked around steel pipe in disorder on scaffold simultaneously, extremely inconvenient.Reviewer's labour intensity is large, and the personnel that need are many, and operating efficiency is not high.
(3) poor stability.Tradition scaffold is barricaded as by hack lever and frame plate, and people walks unstable in the above, and in spherical tank, light is bad, through working for a long time, easily causes danger.
Patent 200920289372.5, introduced a kind of for spherical tank inspection can move freely associated working platform, comprise main couple, top-support, lower support, electrical control system and the removable platform mechanism that works alone.Because this testing environment is in inflammable and explosive place, uses electrical control system to have again and produce pyrophoric possibility, to detecting security presence hidden danger; And its main support partial volume is huge, is difficult for rapid dismounting, has increased technician's workload.This working platform is single can only test in the detection range of 120 degree, has dead angle.Patent 201020156974.6, has introduced a kind of rotating bracket for spherical tank inspection.This support is by runing rest, comprise a head tree, hanging is pressed on the manhole of spherical tank top by the fixing hole of a horizontal arrangement in the upper end of head tree, one pivoted arm that can horizontally rotate and Worker carrying basket composition are set on spherical tank gin pole, Worker carrying basket is connected with gin pole by spiral arm, between spiral arm and gin pole, there is thrust bearing, but lack bearing between hawser and gin pole, in the time that testing staff horizontally rotates around center stand column, due to the additional levels external force of hawser, hanging basket is difficult to ensure balance.This mechanism needs two cover quadric chains, to ensure stress balance, and installation and use inconvenience, in the time that a people enters spherical tank inspection, the setting of mechanism is difficult to make operating personnel to operate in any direction.Because the head tree volume of this device is too huge, cannot realize rapid installation and removal.
It is too huge that above two kinds of patented inventions all exist volume, and installing/dismounting needs a large amount of manpowers, in single testing process, exists measuring tool cannot after any one direction moves or be mobile, keep the problem of balance.To the spherical tank of the inflammable and explosive medium of splendid attire, in actual installation practice process, there is security risk.
Summary of the invention
In order to solve in the time that spherical tank detects, need to build truss work amount large, the cycle is long; Use inconvenience, operating efficiency is low; Poor stability problem.The invention provides the auxiliary manned utensil of the inner regular inspection of a kind of spherical tank, formed by suspension bracket, vertical support column, horizontal support bar and manned work basket.
Suspension bracket is the hinged metal construction of Umbrella frame posture that can strut and pack up, the handle of umbrella frame is hollow steel pipe structure, it is suitable for reading that the handle of umbrella frame upwards exposes spherical tank, and by fixing orifice plate and being bolted on spherical tank upper manhole flange suitable for reading, multiple support end points of the hinged metal construction of umbrella frame while strutting are uniformly distributed along spherical tank inwall around suitable for reading, and each support end points fixedly mounts spring contact; The hinged metal construction of umbrella frame is fixed on spherical tank inwall by supporting end points portion spring contact.
Central axis bottom at the umbrella frame fixing is sequentially fixedly connected with multiple transitional connection pipes vertically downward by flange, forms vertical support column, and the length of vertical support column is a bit larger tham the radius of spherical tank; Be fixed for the thrust bearing of fixing top sheave group on the top of vertical support column.
Be positioned at the equidistant up and down of the central point of spherical tank at vertical support column, respectively the upper thrust bearing of fixed installation and lower thrust bearing; Both sides, radially outer ring at upper thrust bearing and lower thrust bearing fixedly mount respectively two pins for hinged horizontal support bar.
The horizontal support bar of four equal lengths is parallel to each other, and one end is hinged on respectively on four pins of thrust bearing and lower shaft washer, and the other end is hinged on the tie point with manned work basket.
The multiple springs with magnet of end points place fixed installation that approach spherical tank inwall at manned work basket, when work, spring stretches out, and is adsorbed on the inwall of spherical tank.
Fix a manual hoist at manned work basket near horizontal support bar one side; Downslide wheels are fixed on horizontal support bar near manned work basket one end; Top sheave group, downslide wheels and manual hoist composition pulley system, for promoting or the manned work basket that declines.
The present invention is simple in structure, is easy to remove and install, and security performance is high, and operating efficiency is high.
