Abstract
The utility model relates to a rotary lifting platform for operation inside a large ball pot, which mainly comprises a machine base component. A rotary rod is arranged on the upper part of the machine base component and is connected with a hanging column, and the bottom surface of the machine base component is connected with a flange of a manhole of the ball pot through screw bolts. Both ends of a lifting rod are provided with pipe bench vices, and a stabilizer rod is connected to the lifting rod by the pipe bench vices. A steel cable adjacent to a tying knot of a platform is provided with a lifting device. The utility model has the advantages of convenient assembly and safe and reliable use and can greatly shorten the construction period of the ball pot body.
Description
The utility model relates to the rotation and lifting platform that operation is used in a kind of large-size spherical tank.The alternative that belongs to the operation use landing stage of scaffold in the large-size spherical tank.
Multiple enterprise all is provided with large-size spherical tank equipment, for guaranteeing production safety, must regularly open a jar operation that detects, overhauls.The landing stage of scaffold that operation is used in now large-size spherical tank being carried out, its build and disassemble and assemble work extremely required great effort time-consuming, and work capacity is heavy, and is long in time limit.For example for one 1000 cubic capacity spherical tank, the platform that scaffolds erecting needs steel up to the 8-9 ton, and finish and once opened a jar interior operation need 7-8 days, and, because of this situation is often brought enormous economic loss to enterprise.
The purpose of this utility model is to provide that operation is used in a kind of large-size spherical tank executes the commentaries on classics lifting table.This platform structure is simple, tears open and takes conveniently, and is safe and reliable.
For achieving the above object, the utility model is realized by following proposal.Main structure comprises frame component, its following connection davit, wire rope handling ring and supporting sleeve are set on the davit, hinged two stabilizer rods of supporting sleeve symmetry, the davit lower end links to each other with the center of lifting bar with hinged, the external expansion link in the two ends of lifting bar, flexible rod end support platform, the two ends of expansion link and stabilizer rod lower end are shaped on the semi-ring cover, bind cable wire on it, it is characterized in that, dwang of the upper unit of frame component, this bar also is connected with davit, the underrun bolt of frame component links to each other with spherical tank hand-hole flange, at the lifting bar two ends pipe tong is set, stabilizer rod is connected on the lifting bar, on the cable wire that close platform binds lifter is set by pipe tong.
The pressed component that above-mentioned pipe tong adopts comprises the steel link chain of a pocket around stabilizer rod.
Below in conjunction with accompanying drawing the utility model is illustrated.
Fig. 1 is the utility model structural representation.
Fig. 2 is the enlarged drawing of A among Fig. 1, i.e. the supporting sleeve scheme drawing.
Fig. 3 is the enlarged drawing of B among Fig. 1, i.e. the pipe tong scheme drawing.
Fig. 4 is the enlarged drawing of C among Fig. 1, i.e. half collar scheme drawing.
1 is dwang on the frame component among the figure, and 2 is frame component, and 3 is davit, 4 is the wire rope handling ring, and 5 is supporting sleeve, and 6 is stabilizer rod, 7 is lifter, 8 is the expansion link of lifting bar, and 9 is lower platform, and 10 is cable wire, 11 is lifting bar, 12 is upper mounting plate, and 13 pipe tong pockets are around the steel link chain of stabilizer rod, and 14 is the semi-ring cover.
Accompanying drawing is further analyzed, can installation and the using method of clear and definite the utility model in spherical tank.Because primary load bearing davit of the present utility model all adopts hinges to be connected with two stabilizer rods and lifting bar, therefore four rod members can be a branch of body and sent in the jar by the hand-hole place on the spherical tank, four rod members are sent in the tank body, at first frame component is connected with the hand-hole flange fastening the jail, in a certain angle with cable wire pulling stabilizer rod and davit then, swing lifting bar again, make it and davit, stabilizer rod constitutes triangle, with the pipe tong on the lifting bar stabilizer rod is connected then, so davit, lifting bar and stabilizer rod constitute a stable triangular supports, the staff can hold upper right the detection and service work level with both hands at expansion link two, working process, and outer personnel rotate dwang on the support by tank body, the drive platform rotates, and can finish the side face work on the same level height of tank body; By the angle of action pipe tong and lifter change triangular supports, thereby the lifter of implementation platform can be finished the side face work on the tank body differentiated levels, so just can easily carry out omnibearing detection, maintenance to spherical tank.
The utility model is simple in structure, tears open and takes conveniently, and is safe and reliable, can shorten the maintenance duration of spherical tank greatly.
Claims (2)
1, the rotation and lifting platform that operation is used in a kind of large-size spherical tank, it is mainly constructed and comprises frame component, its following connection davit is provided with wire rope handling ring and supporting sleeve on the davit, hinged two stabilizer rods of supporting sleeve symmetry, the davit lower end links to each other with the center of lifting bar with hinged, the external expansion link in the two ends of lifting bar, flexible rod end support platform, the two ends of expansion link and stabilizer rod lower end are shaped on the semi-ring cover, bind cable wire on it, it is characterized in that:
Dwang of the upper unit of frame component, this bar also is connected with davit, and the underrun bolt of frame component links to each other with spherical tank hand-hole flange, at the lifting bar two ends pipe tong is set, by pipe tong stabilizer rod is connected on the lifting bar, on the cable wire that close platform binds lifter is set.
