The utility model has the advantages of simple structure, small size, low manufacture cost, high safety performance and simple and reliable symmetrical control and is extremely convenient and flexible to operate when replacing travelling crane to lift the hull sections so as to greatly reduce the workshop investment of a shipyard.
Description
Technical field
The utility model relates to a kind of boat body section jacking apparatus, it is high with 2.5 meters of its jackings after manufacturing completion specifically to be used for body section, open into the bottom by large-tonnage hydraulic flat car, boat body section jacking apparatus drops on it on hydraulic flat car, the hydraulic flat car pulls away it to and carries out segment folding outside the workshop, belongs to mechanical equipment technical field.
Background technology
Shipyard after manufacturing completion, all is to adopt the large-tonnage driving that it is sling at the Workshop Production body section at present, is placed on the large-tonnage hydraulic flat car, and the hydraulic flat car pulls away it to and carries out segment folding outside the workshop.A general segmentation weighs 200 tons, and height is about 8 meters, so production segmentation workshop must be furnished with the driving more than 200 tons, lifting altitude is more than 12 meters, this factory building investment is huge, and segmentation needs a large amount of hanger of welding before handling, also needs after the handling hanger is cut off.Segmentation is very dangerous in the handling process in addition, and safety misadventure often takes place, and has wasted a large amount of handling time simultaneously.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of boat body section jacking apparatus is provided, and jacking weight is big, can make up in pairs according to the many groups of the size jacking apparatus of segmentation, and operation is very easy flexibly.
Main solution of the present utility model is achieved in that
The utility model mainly adopts the long travel hydraulic actuating cylinder to be installed in the base two ends, and lifting beam is placed on the spherical surface body, links to each other with spherical surface body by anti-down bearing pin, and spherical surface body is by being threaded on the hydraulic cylinder piston rod.Orienting sleeve is fixed on the long travel hydraulic ram by tie bolt, and described hydraulic cylinder piston rod both sides are equipped with test rod with holes respectively, and test rod with holes penetrates orienting sleeve, spherical surface body is fixed by jam nut.
Floatless switch support on the described firm banking, photoelectric switch is fixed on the switch bracket, and is installed in test rod with holes both sides.Described test rod with holes is by spherical surface body and hydraulic ram secured in parallel.
Described hydraulic cylinder piston rod both sides are equipped with test rod with holes respectively.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, volume is little, low cost of manufacture, safety performance height, synchro control are simple and reliable; Replace driving lifting body section with this jacking apparatus, operation is very easy flexibly, reduces the investment of shipyard workshop greatly.
Description of drawings
Fig. 1 is a structural front view under the utility model running condition.
Fig. 2 is A～A cutaway view of Fig. 1.
Fig. 3 is that the jacking apparatus B of Fig. 1 is to view.
Fig. 4 is a structure birds-eye view under the utility model running condition.
The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As Fig. 1～shown in Figure 3: comprise lifting beam 1, anti-down bearing pin 2, jam nut 3, test rod with holes 4, tie bolt 5, orienting sleeve 6, tie bolt 7, switch bracket 8, photoelectric switch 9, hydraulic ram 10, firm banking 11, spherical surface body 12, moulding bed 13, hull translation dolly 14 etc.
Shown in Figure 3, the utility model mainly adopts at the two ends of firm banking 11 two long travel hydraulic rams 10 is installed respectively, lifting beam 1 is placed on the spherical surface body 12, links to each other with spherical surface body 12 by anti-down bearing pin 2, and spherical surface body 12 is by being threaded on hydraulic ram 10 piston rods.Orienting sleeve 6 is fixed on the long travel hydraulic ram 10 by tie bolt 5, described hydraulic ram 10 piston rod both sides are equipped with test rod with holes 4 respectively, test rod 4 with holes is by spherical surface body 12 and hydraulic ram 10 secured in parallel, and test rod 4 with holes penetrates orienting sleeve 6, spherical surface body 12 is fixing by jam nut 3.Switch bracket 8 is on firm banking 11 under the connection of tie bolt 7, and photoelectric switch 9 is fixed on the switch bracket 8 and is installed in test rod with holes 4 both sides.
Principle of work of the present utility model and working process:
As shown in Figure 1, the utility model body section at ordinary times is placed on the high moulding bed 13 of ground 500mm and manufactures, and jacking apparatus is lower than about the 100mm of segmentation bottom surface at ordinary times.
The utility model divides two rows to be installed in hull translation dolly 14 both sides, in one row 2 to 3 section jacking apparatus are arranged, when needs jacking body section, segmentation is moved on the boat body section jacking apparatus by hull translation dolly 14, and boat body section jacking apparatus is high with 2.5 meters of section jackings.These several section jacking apparatus rise simultaneously, and large-tonnage hydraulic flat car is opened into the bottom, and boat body section jacking apparatus drops on it on hydraulic flat car, and the hydraulic flat car pulls away it to and carries out segment folding outside the workshop.
Boat body section jacking apparatus is when lifting, and test rod with holes is lifting simultaneously also, and the photoelectric switch action once when two or many test rod lifting with holes, by photoelectric switch action frequency relatively, is controlled a plurality of hydraulic cylinder synchronous liftings during hole of every mistake.
