Description
Technical field
The utility model relates to a kind of Novel marine detachable blade propellers.
Background technique
It is well known that propeller blade damage phenomenon at shallow-water navigation region, often occurs in ship, propeller is repaired
When, needing to disassemble on propeller can just repair.Existing kind of simple detachable blade propeller peculiar to vessel, it include propeller hub and
Blade, the root of the blade are provided with cushion block, and the cushion block is one of the forming with the blade, the outer end face circle of the propeller hub
Shape array has several grooves compatible with the cushion block, and the cushion block is connected to a fixed with the propeller hub by bolt.It should
Detachable blade propeller has many advantages, such as that structure is simple, easy to maintenance and save production cost, however propeller generally has phase
It to biggish weight, needs when blade is installed by manually lifting or tool is lifted and assembled, so needing two when assembly
Above worker assembles, high labor cost；Simultaneously because blade is heavier, safety problem is easy to happen when manually lifting.For
Making to repair faster and conveniently, usually only removes the blade of damage, propeller is to horizontally suspend state when replacement, due to
The position of centre of gravity for having removed part blade rear screw shaft changes, and the part for having removed blade can be higher in the effect of gravity steering
Position, it is inconvenient when repairing in this way.
Utility model content
Technical problem to be solved in the utility model be overcome the deficiencies of the prior art and provide one kind be easily installed and
Novel marine detachable blade propeller easy to maintenance.
The technical scheme adopted by the utility model is the utility model includes propeller hub and several blades, the blade
Root be provided with cushion block, the cushion block is provided with several L shape blocks far from the blade on one side, is correspondingly arranged on the propeller hub
There are several mounting grooves compatible with the cushion block, the support with several L shape block cooperations is correspondingly provided on the mounting groove
The orifice shapes of slot, the support slot are identical as the maximum cross section of the L shape block, are equipped with and institute in the support slot
The loose slot of the end adapter of L shape block is stated, the cushion block is fixedly connected by bolt with the propeller hub；The L shape block enters institute
After stating support slot certain distance, Xiang Suoshu loose slot is mobile and is inserted into the loose slot, and then the blade is made to be suspended on institute
It states on propeller hub.
By above scheme as it can be seen that by the way that L shape block is arranged on the cushion block and in installation trench bottom setting and institute
The support slot of L shape block adaptation is stated, while is equipped in the support slot for the movable loose slot of L shape block, it is real
The existing L shape block and loose slot cooperation are suspended on the blade on the propeller hub, keep worker described peculiar to vessel new in installation
First the blade can be suspended on the propeller hub when type detachable blade propeller, then pass through bolt again for the cushion block and institute
It states propeller hub to be fixedly connected, and then reaches and be easily installed.The blade needed replacing is cooperated by the L shape block and the support slot
It is first suspended on the propeller hub, and then entire propeller is made to keep relative equilibrium；Simultaneously because when suspension the cushion block with it is described
It is also at regular intervals between mounting groove, make the center of gravity of entire propeller slightly toward the blade needed replacing, makes it downward, just
It is installed in worker.
One preferred embodiment is, when the L shape block is inserted into the loose slot, the lower end surface of the L shape block and the activity
The lower end face contact of slot, the distance between the upper surface of the L shape block and the upper surface of the loose slot are equal to the pad at this time
The distance between the bottom surface of block and the mounting groove, the distance are 1 to 1.5 times of the depth of the mounting groove.
By above scheme as it can be seen that when the blade is hung, the cushion block does not cooperate with the mounting groove, enables the cushion block
Enough length directions along the loose slot move.
Further preferred embodiment is that the distance between the upper surface of the bottom surface of the mounting groove and the loose slot is institute
1 to 1.5 times for stating the vertical range between the root of L shape block and the end face of the L shape block far from the cushion block.
By above scheme as it can be seen that when the cushion block is fixedly connected with the propeller hub, there is sufficient space confession in the loose slot
The L shape block activity, guarantees that the cushion block is closely mounted in the mounting groove.
One preferred embodiment is that the blade is located at the middle section of the cushion block, and the both ends of the cushion block are symmetrical arranged
There are several bolt holes.
Detailed description of the invention
Fig. 1 is the schematic diagram of the section structure of the utility model；
Fig. 2 is the enlarged drawing of part A in Fig. 1；
Fig. 3 is the schematic diagram of the section structure of the utility model other direction.
Specific embodiment
As shown in Figure 1 to Figure 3, in the present embodiment, the utility model includes propeller hub 1 and several blades 2, the blade
2 root is provided with cushion block 3, and the cushion block 3 is provided with several L shape blocks 4 far from the blade 2 on one side, right on the propeller hub 1
Several mounting grooves 5 compatible with the cushion block 3 should be provided with, are correspondingly provided on the mounting groove 5 and several L shape blocks 4
The orifice shapes of the support slot 6 of cooperation, the support slot 6 are identical as the maximum cross section of the L shape block 4, the support
The loose slot with the end adapter of the L shape block 4 is equipped in slot 6, the cushion block 3 connects by the way that bolt and the propeller hub 1 are fixed
It connects.
As shown in Fig. 2, in the present embodiment, after the L shape block 4 enters 6 certain distance of support slot, to the work
Dynamic slot is mobile and is inserted into the loose slot, and then is suspended on the blade 2 on the propeller hub 1.
