Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment one:
Such as Fig. 1, Fig. 2 and shown in Figure 3, the utility model comprises hydraulic motor 1, support 2, and pressing wheel mechanism 3 and pulley assembly 4, described pulley assembly 4 is in transmission connection by a reducing gear 5 with hydraulic motor 2, and reducing gear 5 is a planet gear reduction;
Described support 2 comprises left plate 2.1, right plate 2.2 and hoisting board 2.3;
The shell of described reducing gear 5 by inside be provided with the cylindrical housing main body 5.1 of internal gear, the outer seal 5.2 and the interior capping 5.3 that are connected with two ends, housing main body 5.1 left and right sides respectively consist of, extension Generation Liquid pressure motor stationary magazine creel and pulley support cylinder turn up to the outside of housing main body 5.1 respectively at the middle part of outer seal 5.2 and interior capping 5.3; Outer seal 5.2 consists of the outer end of the shell of reducing gear 5, and it is fixed on the middle part of left plate 2.1 with the left side of bolt structure and support 2; Housing main body 5.1 and interior capping 5.3 consist of the inner of the shell of reducing gear 5, and the inner related gear of being located at the reducing gear in the housing main body 5.1 of the shell of slowing-down structure 5 is beneficial to cramped construction between the both sides of support 2;
The present embodiment, described hydraulic motor 1 is a kind of double speed hydraulic motor, its shell right-hand member is fixedly connected with the left part of screw with described hydraulic motor stationary magazine creel, in the described hydraulic motor stationary magazine creel of end cap 1.1 interior plants of its right-hand member; The output shaft of hydraulic motor 1 is external splines, its with the power shaft 5.4 of reducing gear between adopt the spline structure transmission to link to each other; Connection between reducing gear and the hydraulic motor is easy, is in transmission connection steadily reliable.
The left end of the wheel hub 4.1 of pulley assembly 4 is being held within the shell of reducing gear 5 in described interior capping 5.3 with the rolling bearing rolling support, the right-hand member of the wheel hub 4.1 of pulley assembly 4 with the rolling bearing rolling support in the right side of support 1 within the pulley support seat 2.4 that is connected with described right plate 2.2 end.The present embodiment, pulley support seat 2.4 outer ends are round platform tubular construction (in order to weight reduction), are connected with screw and right plate 2.2.The middle part of the wheel hub 4.1 of pulley assembly 4 is installed with pulley power shaft fixed head 4.2, the left end of pulley power shaft 4.3 is the external splines structure, the right-hand member of pulley power shaft 4.3 passes the locating hole of being located at pulley power shaft fixed head 4.2 middle parts, pulley power shaft fixed head 4.2 is provided with screw, the middle part of pulley power shaft 4.3 is provided with the power shaft retainer ring, and screw and pulley power shaft fixed head 4.2 screws that pulley power shaft 4.3 usefulness are passed the power shaft retainer ring are connected.Pulley assembly 4 is by the output shaft spline joint transmission of pulley power shaft 4.3 with reducing gear 5; Pulley assembly is lightweight, starts easily, and easy with the reducing gear connection, the smooth running that is in transmission connection is reliable;
In order to increase power blocks to the band power of grabbing of fishing net and protection fishing net, the phenomenon of skidding appears when preventing from drawing in the net, and the side of the pulley of pulley assembly 4 is evenly equipped with and increases the block rubber 4.2 that rubs, and the pinch roller 3.1 of pressing wheel mechanism is rubber wheel.
When fishing for end, the primer fluid pressure motor, power blocks starts working that fishing net is received on the ship.When just beginning to draw in the net, netting gear is wet and have fish to be clipped in the net, and comparison of resistance is large, so will use large discharge capacity, plays the low-speed big effect, if the fish folder is many, net cannot get through, and can suitably reverse fish is got rid of down.After net has drawn a part to come up, net weight saving, remaining fish is also few, and can use small displacement this moment, draws in the net speed with increase.The design than before the power blocks of open type gear driving have following advantage:
1. the reducing gear volume that adopts is little, and transmission efficiency is high, and compact conformation is reliable, and is lightweight; Reducing gear is arranged between the frame both sides, has namely reduced the space that power blocks takies, by the center of having improved power blocks.Therefore, power blocks weight is large, mounts difficulty large, and is safe to use.
2. clean environment firendly.The lubricating oil of reducing gear does not spatter loss outside not understanding, and plays the effect of environmental protection, has alleviated daily maintaining and cleaning.
3. the power shaft of reducing gear and output shaft are coaxial, and transmission links to each other with pulley assembly with hydraulic motor with the good spline structure of centering respectively, and connection is easy, and connection reliability is high, is conducive to improve whole power blocks robust motion and security reliability.
Embodiment two:
As shown in Figure 4, the difference of embodiment two and embodiment one, be that mainly embodiment two used reducing gears 5 are the two-stage planet reducing gear, the built-in cylindrical shape product that is installed with in left plate middle part of support 2, this cylindrical shape product the inner is installed with an annular fixed head which is provided with screw, and the outer end of the shell of reducing gear 5 and this annular fixed head are fixed on the housing main body 5.1 of reducing gear 5 with screw.Embodiment two structures are more compact.
Reducing gear among the above embodiment also can be used cycloidal planetary gear speed reducer structure, SB spindle wheel swinging reducer structure and cycloidal planetary gear speed reducer structure instead.The specific embodiment of the above only is the better embodiment of the utility model in a word, is not to limit implementation scope of the present utility model with this.The equivalence that all shapes according to the utility model, structure are done changes and ought to all be included in the protection domain of the present utility model.
