Abstract
The utility model provides an internal automatic lifting platform for sphere tanks, which solves the problems of complicated frame building, poor security, excessive affiliated equipment and low efficiency. The internal automatic lifting platform for sphere tanks is formed by assembling a pillar, an upper and a lower stabilizer blades, an inner platform, a swing arm and a draw rod. The utility model has the advantages of simple structure, convenient transportation, flexible operation, safety, reliability, repeated use of parts, convenient assembly and disassembly, and wide purpose. The utility model is especially suitable for welding, polishing, flaw detection, painting, etc., during construction and overhauling in the sphere tank.
Description
The utility model relates to a kind of self-raising platform, be particularly suitable for being used in interior construction of spherical tank and the maintenance automatic lifting workbench of operations such as welding, polish, detect a flaw, spray paint.
At present in the construction and maintenance of spherical tank, mainly be that the method that the trellis scaffold is taken in personnel selection satisfies construction requirement.This method poor stability, handicapped, the built time is long, and repeat usage is low, and the Soviet Union once proposed a kind of " facility that the spherical tank interior construction is used " (patent 618519 in 78 years).Articulating two people bracketplant by jacking system and cantilever moves along the spherical tank inwall.This improved facility is regulated flexibly, is applicable to maintenance, but owing to can not provide many people to use simultaneously, does not satisfy the welding procedure requirement, because the big thing of facility body is heavy, needs large-scale accent equipment during installation, otherwise column can't be installed in addition.
In view of the foregoing, the purpose of this utility model is will provide a kind of to be suitable in interior construction of spherical tank and the maintenance, and purposes is wide, installs and removes easy, easy to use and reliable automatic lifting workbench.
Workbench mainly comprised swing arm (2), pull bar (3) and the hoist engine (14) of column (5), inner platform (1) and location usefulness in the utility model was achieved in that.Column (5) is connected with upper and lower leg (13) (4) by stand bar seat (18), upper and lower leg (13) (4) is supported on the inwall of spherical tank, at column (5) middle part fixedly U type spare (6) is housed, U type spare (6) is connected with pull bar (3) with swing arm (2) by bearing pin (19), the other end at swing arm (2) and pull bar (3) is being connected inner platform (1), make column (5), swing arm (2), pull bar (3) and inner platform (1) form a flat shape quadrangle, to guarantee the eternal parallel ground of work top.Hoist engine (14) is housed on the inner platform (1),, determines the operating position with the lifting of control inner platform (1).Hawser (8) termination of hoist engine (14) is connected with column (5) upper end.Available suspension hook (9) connects.The upper and lower leg (13) (4) that interior workbench adopts can respectively have three at least, uses wire rope (12) serial connection location respectively, and the Lever Blocks (11) of fastening usefulness is housed on the wire rope of last leg (13).In addition, column (5), cantilever (10) are to be formed by connecting with bolt (17) by welded unit (16), and pull bar (3) is an incident, has different length plurality of specifications, and during installation, its length can be adjusted and selects for use according to the size of spherical tank capacity.The cantilever (10) of going up available security insurance rope (7) and column (5) at inner platform (1) is connected, and rises at a slow speed or descends as safeties and control inner platform with Lever Blocks (11) is fastening.Can use positioner (15) to connect between column (5) and upper and lower stand bar seat (18), workbench can manually rotate easy access in making.One and many inner platforms (1) can be installed on column (5) in addition, symmetric arrangement, at many inner platforms (1) overlap joint pedal (20), the looping work top is in order to construction.
Use the automatic lifting workbench in the spherical tank that the utility model provides, because all component all are to adopt bolt to be connected with bearing pin, and interior workbench supports the location by last lower support leg, compare with above-mentioned prior art, this automatic lifting workbench, transportation is convenient, does not need other lifting appliance and ancillary service during installation.According to the different requirements of construction and maintenance and the requirement of varying number workbench, can be assembled into the automatic lifting workbench of suitable different capabilities, dissimilar spherical tanks rapidly, easily.Installation work-hour is few.This automatic lifting Working table structure is simple, be convenient to make, component are reused, flexible and convenient operation, safe and reliable, purposes is wide, and problem such as solved built complexity in the spherical tank operation, poor stability, ancillary service is many, efficient is low is a kind of automatic lifting workbench that is suitable for being used in the construction and maintenance in the spherical tank operations such as welding, polish, detect a flaw, spray paint.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the structure principle chart of interior workbench
Fig. 2 is interior workbench rotation positioner structure principle chart
Fig. 3 is a U type spare connection diagram
Fig. 4 is interior annular working table top
During use, earlier the whole component of workbench and welded unit are hung spherical tank inside with self hoist engine, assemble swing arm earlier, the first segment welded unit that to go up leg and column earlier with upside-down method of hull-section construction connects with bolt again, sling with self hoist engine, connect the second joint welded unit with bolt, connect the 3rd joint in turn until lower support leg is installed.
The column cross dimensions is 400mm * 400mm, and the welded unit element length is one meter, can form the long column of 6-16 rice.Upper and lower leg respectively has three, locatees with wire rope respectively.The positioning wire rope of last leg is strained with Lever Blocks: column is pushed up securely stand in spherical tank inside.One of the swing arm that assembles is sling, be connected and fixed with the U type spare at column middle part, pull bar is installed again, and last installation dimension is the hoist engine that 1 meter * 2 meters load-bearing inner platform that is 400kg and lifting capacity are 1000 kilograms, and the wire rope on the hoist engine is connected with suspension hook on the column.At this moment start hoist engine, can drive inner platform and move along the spherical tank inwall is upper and lower.For ease of maintenance, during installation, can between upper and lower leg and column, be connected, in order to manual rotation with positioner.One or more inner platform co-operation can be installed as required, Fig. 4 has installed 12 inner platforms, and the schematic diagram of the interior annular working table top of overlap joint pedal, safety rope or theft-resistant link chain also can be set as handrail, the staff on the same plane is worked simultaneously.In order to guarantee safety, behind the inner platform location, be connected with column upper end cantilever from termination, inner platform both sides with two safety ropes, strain with Lever Blocks.When the inner platform need are mobile, need unclamp safety rope earlier.This workbench can with spherical tank with the supporting use of outer automatic lifting workbench: to improve the efficient and the quality of spherical tank construction.
