Abstract

The utility model relates to a workbench for testing the inner side of a spherical tank. A central upright post (2) is positioned at an upper central access hole and a lower central access hole of the spherical tank by an upper support (5) and a lower support (1). The fulcrum end of a deflector rod (4) is hinged at the middle part of the upright post, and the rounded end of the deflector rod (4) is hinged with the supports of the workbench. A lifting device (7) is fixed at the upper support of the workbench. Both ends of a twisted rope (6) are respectively connected with the rounded end of the deflector rod and the lifting device by that the twisted rope (6) hangs a pulley on a liftinglug which is welded at the upper part of the upright post. The upright post can support three sets of deflector rods and be connected with three workbenches furthest, and contains six people to work. Inspectors manipulate the lifting device, namely drag the deflector rod and the workbench to swing and lift. The inner wall of the spherical tank is pushed by hands, and follows upright post to swing in a circumferential direction so as to arrive at the position which needs testing to implement the internal test of the spherical tank comfortably, safely and quickly.

Description

Spherical tank inner survey bench board

Affiliated technical field

The utility model relates to a kind of spherical tank inner survey bench board, a kind ofly can provide three to detect the scope of operations, and each scope of operation can be held the spherical tank inner survey bench board that two people implement to check operation simultaneously.

Background technology

Know with the regular cut out test of spherical tank, no matter be band, be not with, be with dismountable type still to be with the non-disconnectable inner ladder landing platform of type that removes, at present without exception all be to adopt the way of taking interim inside staging, operational security and happy degree are poor on scaffold, detection accuracy is influenced, introducing had revolution to hang basketball jar inner survey bench board in the spherical tank, but hanging the column of blue structure, revolution can only support circular table of connection, hold people's operation, can't satisfy of short duration actual needs of duration.

Summary of the invention

The utility model provides a kind of spherical tank inner survey bench board, this bench board is that the driving lever tricks and the bonded assembly bench board number that make revolution hang blue structure spherical tank inner survey bench board column upper support no longer limit to one in one, can be to be mutually 180 degree two of angles, also can be to be mutually 120 degree three of angles, the bench board bottom surface can singlely also can be the double Long Circle of using with circle, detection scope of operation number that provides and open ended operation number, be increased to 3 and 6 respectively by original 1 the most for a long time, thereby thoroughly solved scaffold, deficiency and inapplicable problem that basketball jar inner survey bench board is hung in revolution.

The technical scheme that its technical matters that solves the utility model adopts is: the column as axis of revolution is located on the manhole of the upper and lower center of spherical tank by upper support and lower support respectively; The support end of driving lever is articulated in the column middle part, and the support of its round end and bench board is hinged; Bont is with the upper support of bolt in bench board; Twisted rope welds pulley on the hanger by hanging over column top, two ends respectively with the round end of driving lever with carry opening apparatus and be connected.Column has whole and merogenesis to tie and be connected into as a whole two kinds of structures with connecing valve snail again, and middle part institute is with driving lever bonded assembly articulated element single shape being arranged, being mutually 180 and spending the symmetric figure at angles and be mutually 120 quincunx three kinds of structures of spending angles; Driving lever has fixed length welding shape and two kinds of structures of telescopic retractable shape; The bench board bottom surface has single with circular and double two kinds of the Long Circles of using.Inspection man author stays on the bench board and oneself handles bont, twisted rope drags driving lever and bench board rotary and lifting in perpendicular, utilize action and reaction power principle, hand push spherical tank inwall, bench board is promptly with column circumferentially revolution in horizontal surface, two gyroscopic movement combinations arbitrarily arrive the inner any inspection position that needs of spherical tank.When the articulated element of change column middle part institute band three kinds of planforms that are connected with driving lever, promptly form on the root post respectively with one overlapping, two overlapping maximum three three kinds of different structures that overlap bench board; When change bench board bottom shape, promptly form single stance with circular and double stance with two kinds of different structures of oval formation; When the driving lever combination of whole column and fixed length welding shape, promptly only be applicable to the structure on a plurality of spherical tanks of same diameter; When the column of merogenesis and the combination of telescopic retractable shape driving lever, promptly obtain applicable to the structure on a plurality of spherical tanks of different-diameter.Though local change combination is varied, general plotting is identical with structural principle, and these different combinations changes have formed serial like product.

The beneficial effects of the utility model are flexible and changeable use more, can satisfy and use diameter series scope, the scope of operation what, requirement that operating environment level of comfort aspect is different, scope of operation number and operation number, be increased to 3 and 6 respectively by 1, shorten significantly and detect the duration, make dismountable type spherical tank inner survey bench board really practical.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified

Fig. 1 is the physical structure simplified schematic diagram of first embodiment among three embodiment of spherical tank inner survey bench board.

Fig. 2 is that the A-A of Fig. 1 analyses and observe, and this figure has removed assembly 1 and assembly 6.

Among the figure, 1. lower support 2. columns 3. bench board 4. driving levers 5. upper supports 6. twisted rope pulleys 7. bonts

The specific embodiment

In first embodiment shown in Figure 1, the steady ring of lower support (1) embeds manhole adapter in center under the spherical tank, and several supporting legs place on the spherical tank inwall, and the rotation end that the rotating stand of antifriction-bearing box is equipped with in the upper end is connected with column (2) lower end to connect the valve snail bolt; Cover column (2) constitutes plain bearing in the steady ring of upper support (5), and the steady ring overhanging arm is with bolt manhole flange in center on spherical tank; Column (2) merogenesis ties and is connected into an one rotating shaft with connecing valve snail, the middle part be mutually 120 degree angles quincunx with articulated element, hinged with the support end of the three cover scalable driving levers of telescoping (4) respectively; The support of the round end of driving lever (4) and bench board (3) is hinged; Bont (7) uses bolt on the upper support of bench board (3), twisted rope (6) welds the pulley on the hanger by being hung on column (2) top, two ends are connected with bont (7) with the round end of driving lever (4) respectively, constitute and support three cover driving levers (4) on the root post shown in Figure 2 (2) simultaneously, connect the structure of three bench board (3).

The difference of embodiment shown in the structure of second embodiment and Fig. 1, only be that column (2) middle part institute is to be mutually 180 symmetric figures of spending angles with articulated element, constitute and support two cover driving levers (4) on the root post (2) simultaneously, connect the structure of two bench board (3).
