Abstract
The utility model relates to a special lifting tool for a circulating tube, which comprises a polygonal base plate, a guide rod, a sliding sleeve, at least three connecting blocks, at least three connecting rods and at least three butting blocks, wherein one end of the guide rod is vertically fixed at the middle part of the base plate, and a hoisting ring is arranged at the other end of the guide rod; the sliding sleeve is sleeved on the guide rod; one end of all the connecting blocks is movably connected on the edge of the base plate and is evenly distributed along the edge of the base plate; one end of the connecting rods is movably connected on the sliding sleeve, and the other end of the connecting rods is connected on the connecting block; and the three butting blocks are respectively and correspondingly fixed at the outer ends of the connecting blocks, and the butting blocks are triangular. The special lifting tool for the circulating tube has a triangular design with the contact points of the butting blocks contacted with the RH circulating tube, the outer end side is an inclined surface, and the stability is obviously enhanced during the hoisting process; the phenomenon that the suspension centre slides off during the hoisting process to cause the circulating tube to slide off and be damaged is eliminated; the service cycle of the lifting tool is obviously prolonged, and the lifting tool can be disassembled and replaced at any moment after being worn; the construction progress and the quality are ensured, and the potential safety hazard is eliminated.
Description
Technical field
The utility model relates to a kind of suspender, relates in particular to a kind of circulating pipe special hanger.
Background technology
In RH refining zone, the replacing of circulating pipe is one of link more important in the whole worker's work progress of RH.In the cast and replacing process of circulating pipe, the handling circulating pipe is particularly important to the safe and construction speed, the construction quality that ensure the operating personnel.
Because the particularity of RH circulating pipe lifting, the suspender of falling the umbrella that adopts carries out lifting construction at present, but in the contact and this construction link of circulating pipe internal diameter contact surface of suspender, because suspender is the oblong contact, following problem occurs through regular meeting:
1, the RH circulating pipe is in when installation, and suspension centre is tried to shirk responsibility and often caused the circulating pipe phenomenon of damaging that comes off to happen occasionally, and execute-in-place worker's inherently safe can't be protected.
2, suspender contact operating cycles is short, must be through reusing after the built-up welding polishing again after the use.
3, the contact point of suspender and RH circulating pipe is 6 points.In the process of installation lifting, stablize, do not have when trying to shirk responsibility omen inadequately, have very big potential safety hazard.
4, construction speed can not be finished on time, and construction quality is affected.
Summary of the invention
The purpose of this utility model is to provide a kind of circulating pipe special hanger, can prevent that circulating pipe from trying to shirk responsibility, and guarantees job safety.
For achieving the above object, the technical solution of the utility model is:
A kind of circulating pipe special hanger, it comprises: substrate is polygon-shaped; Guide rod, the one end is vertically fixed on the middle part of substrate, and the other end is established suspension ring; Sliding sleeve is set on the guide rod; At least three contiguous blocks, an end of each contiguous block is movably connected in the edge of substrate, along the substrate edges rectangular distribution; At least three connecting rods, this connecting rod one end is movably connected on the sliding sleeve, and the other end is connected on the contiguous block; At least three butt pieces, the corresponding respectively outer end of being fixed in contiguous block, this butt piece is triangular in shape.
Again, side, described butt piece outer end is the inclined-plane.
In addition, described contiguous block outer end stretches out and forms a leg-of-mutton groove that is complementary with the butt piece, and the butt piece is fixed in this groove.
The end sides of described contiguous block outer end groove is the inclined-plane, with the inclined-plane coupling of side, described butt piece outer end.
Establish a bolt that can be fixed on the guide rod on the described sliding sleeve.
The beneficial effects of the utility model:
The contact point design triangular in shape of the butt piece that the utility model circulating pipe special hanger will contact with the RH circulating pipe, and outer distolateral be the inclined-plane, obviously raising of stability when making lifting; The phenomenon of having tried to shirk responsibility and having caused circulating pipe to come off and damage because of suspension centre when having eliminated lifting; The suspender operating cycles obviously prolongs, and can carry out dismounting and change at any time after the wearing and tearing; Guarantee construction speed, quality, eliminated potential safety hazard.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment;
Fig. 2 is the scheme drawing of the utility model contiguous block and butt piece.
The specific embodiment
Describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
See also Fig. 1, Fig. 2, circulating pipe special hanger of the present utility model, it comprises: substrate 1 is polygon-shaped; Guide rod 2, the one end is vertically fixed on the middle part of substrate 1, and the other end is established suspension ring 21; Sliding sleeve 3 is set on the guide rod 2; Three contiguous blocks 4, an end of each contiguous block 4 is movably connected in the edge of substrate, along substrate 1 edge rectangular distribution; Three connecting rods 5, this connecting rod one end is movably connected on the sliding sleeve 3, and the other end is connected on the contiguous block 4; Three butt pieces 6, the corresponding respectively outer end of being fixed in contiguous block 4, this butt piece 6 is triangular in shape, and side, butt piece 6 outer end 61 is the inclined-plane.
Described contiguous block 4 outer ends stretch out and form a leg-of-mutton groove 41 that is complementary with butt piece 6, and butt piece 6 is fixed in this groove 41 by screw 7; 411 sides, end of this groove 41 are the inclined-plane, with the inclined-plane coupling of side, described butt piece 6 outer end 61.Establish a bolt 8 that can be fixed on the guide rod 2 on the described sliding sleeve 3.
During the work of the utility model circulating pipe special hanger, by sliding sleeve 3 along moving on the guide rod 2, turn on the contiguous block 4 of drive guide rod 2 one ends, on contiguous block 4 outer distolateral butt pieces 6, turn over and pack up, put into the RH circulating pipe then, put down sliding sleeve 3, make butt piece 6 fall to decontroling, at this moment, butt piece 6 design-calculated contact point contact RH circulating pipes triangular in shape, and distolateral outward is the inclined-plane, and stability obviously improves when making lifting.
