Abstract
The utility model relates to a device for installing a hydraulic nut during the installation of screw shafts of ships, which is a structure for supporting the hydraulic nut on an installation position and is composed of a pair of roller wheels (4) and a support frame for installing the roller wheels (4), wherein the roller wheels (4) are respectively arranged at both sides of the hydraulic nut, and rolling shafts (5) for the roller wheels (4) are parallel with the shaft line of the hydraulic nut. The device for installing the hydraulic nut during the installation of screw shafts of ships causes the roller wheels to directly contact the surface of the outside diameter of the hydraulic nut, and the free and flexible rolling of the roller wheels ensures that the hydraulic nut can be easily pushed and rolled by manpower, thus compared with the prior art, the utility model can save the manpower and has labor conservation, convenient installation and increased working efficiency.
Description
Technical field the utility model relates to hydraulic efficiency nut erecting device in a kind of screw shaft of ship installation, belongs to the Marine engineering technical field.
Background technology is along with China builds the increase gradually of tonneaux de jauge, and the diameter of hydraulic efficiency nut that is used for effect such as set and locking screw oar on the screw shaft of ship is also increasing thereupon, and its weight has reached more than the hundreds of kilogram, can't control installation with manpower.Existing field engineering is with wirerope the outer ring of hydraulic efficiency nut to be entangled, and works the axle center that winches to the stern tube shaft outer end, by the support of stern tube shaft end, with manpower hydraulic efficiency nut is tightened stern tube shaft.Because there are certain friction force in lifting back steel wire and hydraulic efficiency nut outer ring, therefore, rotate hydraulic efficiency nut and take very much manpower, cooperating with the installation of stern tube shaft end neither be very convenient, and work efficiency is not high.
Summary of the invention is at above deficiency, and the utility model provides a kind of can save manpower, make things convenient for hydraulic efficiency nut erecting device in the screw shaft of ship installation of installing, improving work efficiency.
Hydraulic efficiency nut erecting device during described screw shaft of ship is installed, be one hydraulic efficiency nut to be supported on structure on the installation site, by a pair roller that places hydraulic efficiency nut both sides, the axis of rolling and hydraulic efficiency nut parallel axes respectively and install that the bracing frame of roller constitutes.
Hydraulic efficiency nut erecting device during described screw shaft of ship is installed makes roller and hydraulic efficiency nut external diameter surface direct contact, because roller can freedom and flexibility roll, has guaranteed that hydraulic efficiency nut can be easily by the push-jump rolling of manpower.This shows that compared with prior art the utility model can be saved manpower, convenient installation, improve work efficiency.
Hydraulic efficiency nut erecting device during described screw shaft of ship is installed, said bracing frame also comprises upright steel bar and horizontal steel bar except that sole, upright steel bar and horizontal steel bar lay respectively at outside the front and back end of hydraulic efficiency nut, hydraulic efficiency nut be placed on upright steel bar and inside the holding frame that laterally steel bar constitutes, prevent that the hydraulic efficiency nut side.
Hydraulic efficiency nut erecting device during described screw shaft of ship is installed, said roller is an antifriction-bearing box, and grouping is installed in the two ends of bearing axle, with the weight of steady bearing hydraulic nut, two ends in bearing axle also are equipped with the adjusting back-up ring, in order to regulate the bearing point of bearing and hydraulic efficiency nut.
Hydraulic efficiency nut erecting device during described screw shaft of ship is installed on the bracing frame that roller is installed, is equipped with safety block, and some exceeds safety block roller and keep off outside hydraulic efficiency nut, makes at hydraulic efficiency nut can deflection not go out the position when rotating.
Hydraulic efficiency nut erecting device during described screw shaft of ship is installed, said horizontal steel bar is a detouchable with upright steel bar, the stress point of a lifting is arranged at said upright steel bar top.
Description of drawings Fig. 1 is the structural representation of hydraulic efficiency nut erecting device during a kind of screw shaft of ship in the utility model is installed, and among the figure: 1-lifts by crane upright angle steel, and 2-laterally insures angle steel, the 3-hydraulic efficiency nut, 4-cylindrical roller bearing, 5-axle, 6-angle stay bearing plate, 7-sole, 8-safety block;
Fig. 2 is A among Fig. 1---the A section-drawing, and among the figure: 1-lifts by crane upright angle steel, and 2-laterally insures angle steel, the 3-hydraulic efficiency nut, the 4-cylindrical roller bearing, the 5-axle, 6-angle stay bearing plate, the 7-sole, the 8-safety block, the 9-bearing is regulated back-up ring.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, 2, holding frame is to be welded to each other by four upright angle steel of lifting 1, four angle stay bearing plates 6 and sole 7 to form a single-piece pedestal, article two, laterally insurance angle steel 2 with lift by crane upright angle steel 1 and be connected as bolt, on each angle stay bearing plate, live safety block 8 with bolt, two of the axle 5 of each group roller devices is placed in respectively on the notch of an angle stay bearing plate 6, and the both sides on it have been installed respectively by one group of cylindrical roller bearing 4 and pair of bearings is regulated back-up ring 9.
During use, earlier two groups of roller devices are placed in respectively on the notch of angle stay bearing plate, then, the mechanical force hydraulic efficiency nut of slinging is put the pedestal the inside of holding frame into, then will laterally insure angle steel with bolt is fixed on the upright angle steel of lifting, with bolt safety block is fixed on the stay bearing plate of angle, guarantees hydraulic efficiency nut can only be rotated, can not move axially or side is fallen.Then, hook the stress hole on the upright angle steel of lifting top, steadily sling, be displaced to center, stern tube shaft end, can tighten stern tube shaft to hydraulic efficiency nut easily with manpower.
