Embodiment 1

[0016] like figure 1 , figure 2 and image 3 As shown, the present invention includes a hydraulic motor 1, a bracket 2, a pressure roller mechanism 3 and a pulley assembly 4, and the pulley assembly 4 is transmission-connected to the hydraulic motor 1 through a reduction mechanism 5 whose axis of the input shaft and the axis of the output shaft are collinear , the deceleration mechanism 5 can adopt a planetary gear deceleration mechanism, a cycloidal pinwheel deceleration mechanism, an SB pinwheel cycloidal deceleration mechanism and a planetary cycloid deceleration mechanism, and the deceleration mechanism 5 of the present embodiment is a planetary gear deceleration mechanism;

[0017] The bracket 2 includes a left side plate 2.1, a right side plate 2.2 and a lifting plate 2.3;

[0018] The shell of the reduction mechanism 5 is composed of a cylindrical shell main body 5.1 with an internal gear inside, an outer cover 5.2 and an inner cover 5.3 fixedly connected to the left...

Embodiment 2

[0027] like Figure 4 As shown, the difference between Embodiment 2 and Embodiment 1 is that the reduction mechanism 5 used in Embodiment 2 is a two-stage planetary gear reduction mechanism, and a cylindrical part is fixed in the middle of the left side plate of the bracket 2. The cylinder The inner end of the shaped part is fixedly provided with an annular fixed plate with a screw hole on it, and the outer end of the shell of the speed reduction mechanism 5 and the annular fixed plate are fixedly connected to the shell main body 5.1 of the speed reduction mechanism 5 with screws. Embodiment 2 has a more compact structure.

Abstract

The invention discloses a power block for hauling nets. The power block for hauling the nets comprises a hydraulic motor, a support, a pressing wheel mechanism and a pulley assembly. The pulley assembly and the hydraulic motor are connected in a transmission manner by a reducing mechanism of which the axis of an input shaft and the axis of an output shaft are collinear; the outer end of a shell of the reducing mechanism is fixedly connected with one side of the support; the inner end of the shell of the reducing mechanism is located between both sides of the support; the shell of the hydraulic motor is fixedly connected with the outer end of the shell of the reducing mechanism; and both ends of a hub of the pulley assembly are respectively supported at the inner end of the shell of the reducing mechanism and the other side of the support in a rolling manner. The power block for hauling the nets has the advantages that the structure is compact; the operation is stable and reliable; the service life is long; the energy consumption is low; the environment cannot be polluted; and the maintenance work load is light in daily use.

Description

technical field [0001] The invention relates to a fishing tool, in particular to a power block used for retracting and releasing fishing nets on a fishing boat. Background technique [0002] The power tackle for lifting the net is a device used when retracting and unwinding the seine. The authorized announcement date is 2011.01.26, the authorized announcement number is CN201718338U, and the Chinese patent document named "single motor power tackle" discloses a power tackle for lifting nets, which "includes a bracket, and the bracket is provided with a pulley body assembly.
