Abstract
The utility model provides a double-crane lifting freely-unhooking device, which comprises a reinforced beam fixing pin shaft. The tail end of the reinforced beam fixing pin shaft is bent to form a bent section, a gasket is welded on the bent section, and the gasket is connected with a pulling rope. The double-crane lifting freely-unhooking device adopts a method of free unhooking, thereby not requiring a rope ladder to unhook at high altitude and reducing high-altitude operation amount and danger of high-altitude operations. The reinforced beam fixing pin shaft and a fixing lug plate are used as lifting lugs, thereby eliminating work amount of welding lifting lugs and cutting off the lifting lugs at high altitude.
Description
Technical field
The utility model relates to lifting and hangs technical field, specifically is that a kind of two-shipper lifts free trip mechanism.
Background technology
Present domestic large electric power plant unit is installed, and the unit block assembly rack of the general usage level of boiler water wall tube panel carries out the device ground combination, lifts needs for satisfying, and also must weld interim hanger as the Heave Here, adopts two-shipper with the cocked setting of assembly during lifting.
Cooperate the crane binding rope lift to be difficult for breaking off relations when but two-shipper lifts, lift cocked after, need set up the destructing of just getting on of rope ladder crane man.Owing to need climb up and carry out aloft work on the rope ladder, increase amount of high-altitude operation and danger; In addition, the interim hanger of welding also needs to cut off, and the time of cutting off interim hanger in the practical operation is longer, has so just influenced the lifting time, also influences the time of installation in place in succession.
Summary of the invention
The utility model provides a kind of two-shipper to lift free trip mechanism, can solve the problem that it is difficult to break off relations in the high-altitude, reduces amount of high-altitude operation simultaneously, reduces the operation danger factor, increases work efficiency.
A kind of two-shipper lifts free trip mechanism, comprises the buttress bracing struts fixed pin shaft, and the tail end of buttress bracing struts fixed pin shaft is bent to form bending part, is welded with pad at bending part, pad with pull the rope be connected.
Aforesaid two-shipper lifts free trip mechanism, and the buttress bracing struts fixed pin shaft is used for inserting one group of buttress bracing struts fixedly otic placode and the crane rope Eight Diagrams head on the water screen tube, and pad is connected with crane rope Eight Diagrams head by safety rope.
The utility model adopts and freely breaks off relations, and can not need to set up rope ladder and carry out the high-altitude uncoupling, reduces amount of high-altitude operation and aloft work danger; Use the buttress bracing struts bearing pin and fixedly otic placode can save the work capacity that hanger is cut off in welding hanger and high-altitude as lifting hanger.
Description of drawings
Fig. 1 is that the utility model two-shipper lifts the birds-eye view of free trip mechanism when installing and using;
Fig. 2 is that A among Fig. 1 is to view;
Fig. 3 is that B among Fig. 1 is to view.
Among the figure: 1-Bailey wall upper collecting chamber, the 2-panelized-tube-wall section, the 3-buttress bracing struts is otic placode fixedly, the 4-trip mechanism, the 5-water screen tube, the 6-fin, 7-crane rope Eight Diagrams head, 41-buttress bracing struts fixed pin shaft, the 42-bending part, the 43-pad, 44-pulls rope, the 45-safety rope.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model, the technical scheme in the utility model is clearly and completely described.
Figure 1 shows that the utility model two-shipper lifts the birds-eye view of free trip mechanism when installing and using, please in the lump referring to figs. 2 and 3, the bottom of Bailey wall upper collecting chamber 1 is connected with the upper end of many water screen tubes 5, the both sides of every water screen tube 5 are provided with fin 6, and the fin 6 of many water screen tubes 5 is welded to each other and forms panelized-tube-wall section 2.
Every water screen tube 5 keeps at a certain distance away and is welded with fixedly otic placode 3 of one group of buttress bracing struts, and the utility model trip mechanism 4 is located in wherein one group of buttress bracing struts fixedly in the otic placode 3.
Concrete, described the utility model trip mechanism 4 comprises buttress bracing struts fixed pin shaft 41, and the tail end of buttress bracing struts fixed pin shaft 41 is bent to form bending part 42, is welded with pad 43 at bending part 42, and pad 43 44 is connected with pulling to restrict.
During use, choose four suitable locations point in the bottom of panelized-tube-wall section 2, respectively four trip mechanisms 4 are inserted into four groups of buttress bracing strutss fixedly in the otic placode 3, concrete, the buttress bracing struts fixed pin shaft 41 of trip mechanism 4 inserts the fixedly fixing otic placode 3 of otic placode 3, crane rope Eight Diagrams 7, another one buttress bracing struts of one of them buttress bracing struts from the bottom to top successively, and the bending part 42 of buttress bracing struts fixed pin shaft 41 tail ends rests on the end (as shown in Figure 1) by panelized-tube-wall section 2 bottoms.The other end of crane rope hangs on the suspension hook of gauntry crane, and two 600t hook suspension centres are set on the Bailey wall upper collecting chamber 1, and the upper end of panelized-tube-wall section 2 is provided with the little hook block point of 600t.
Like this, can use buttress bracing struts fixed pin shaft 41 and utilize buttress bracing struts fixedly otic placode 3 saved the work of welding interim hanger as the lifting suspension centre of gauntry crane.Preferable, pad 43 also can be connected by safety rope 45 and crane rope Eight Diagrams 7, prevents that trip mechanism 4 from falling from the high-altitude.
After assembly (Bailey wall upper collecting chamber 1, panelized-tube-wall section 2, water screen tube 5) is cocked, buttress bracing struts fixed pin shaft 41 of the present utility model is under the effect of gravity, can fixedly come off the otic placode 3 from its buttress bracing struts that wears, if bite is then available to pull rope 44 it is fixedly pulled out the otic placode 3 from buttress bracing struts, reach the purpose that freely breaks off relations.
The utility model adopts and freely breaks off relations, and can not need to set up rope ladder and carry out the high-altitude uncoupling, reduces amount of high-altitude operation and aloft work danger; Use the buttress bracing struts bearing pin and fixedly otic placode can save the work capacity that hanger is cut off in welding hanger and high-altitude as lifting hanger, specifically see the following form:
The above; it only is the specific embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly belong to those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
