CN202765247U - Double-motor transmission broadside roller - Google Patents

Abstract

The utility model discloses a double-motor transmission broadside roller which comprises a swing frame group which is composed of a plurality of swing frames. One end of the swing frame group is provided with a motor, and the other end of the swing frame group is also provided with a motor. In the double-motor transmission broadside roller, through the arrangement of the motors on two sides of the swing frame group, the motors on the two sides of the swing frame group drive the roller to rotate. Accordingly, the power of the needed motors is reduced, the size of the motors is small, and manufacturing cost is low.

Description

A kind of topside cylinder of duplex set

Technical field

The utility model relates to a kind of fishing boat and fishes for equipment, more specifically, relates to a kind of topside cylinder of duplex set.

Background technology

For fishing for of saury, when putting net, cast fishing net from a side of ship side first, the upper end of fishing net is provided with the bamboo pole float, with push rod the bamboo pole float is shifted onto position away from ship side, the upper end of net relies on the bamboo pole buoys float on the upper strata on sea, and the lower end of net is provided with sinker, because the lower end of the effect net of sinker sinks naturally; When receiving net, rely on the topside cylinder, etting is drawn in the ship.

The described middle ship side cylinder of preamble is the rotatingcylindrical drum that rubber coating is applied in a kind of outside, be arranged on the ship side, during hauling by the cylinder of rotation and the friction force between the etting with etting band upper deck.This equipment is finished the operation of collecting etting as the corollary equipment of power blocks on fishing boat.Owing to can save a large amount of labours, reduce labor intensity, reduce the netting gear wearing and tearing, improving output and economic benefit, generally using on the fishing boat of China now.

Generally the size according to fishing boat is equipped with many group topside cylinders at the fishing boat board, and each organizes the motor driven by at one end upward arranging between the topside cylinder, and this topology requirement propulsion source power is large, thereby makes propulsion source motor volume excessive.Manufacturing cost is higher, and also very inconvenient in the fishing boat installation.

Summary of the invention

For the deficiencies in the prior art, the utility model provides a kind of topside cylinder of duplex set, and actv. has solved traditional single motor and driven greatly to the motor demand power, causes the excessive drawback of motor volume.

The utility model is achieved by following technical proposals: a kind of topside cylinder of duplex set, comprise the swing span group that several swing spans form, end in described swing span group is provided with motor, also is provided with motor at the other end of swing span group.

In the technique scheme, also comprise a connecting shaft cover, be arranged with the drum drive axle in the described swing span, described motor comprises output shaft, described connecting shaft puts and is respectively arranged with in drum drive axle and corresponding the first groove and the second groove of output shaft, described output shaft is connected and fixed in the second groove by key, and described drum drive axle is connected and fixed in the first groove by key.

In the technique scheme, offer tapped bore on the sidewall of described connecting shaft cover, described tapped bore and the first groove are communicated with, and twist in described tapped bore and establish bolt, and described bolt leans the drum drive axle.

The utility model compared with prior art has following beneficial effect: the both sides in the swing span group are provided with motor, drive the rotation of cylinder, thereby have reduced the power of required motor, so that the motor volume is less, manufacturing cost is lower.

The specific embodiment

Below in conjunction with accompanying drawing and the specific embodiment the utility model is described in further detail: referring to Fig. 1, Fig. 1 is structural representation of the present utility model, comprise by the swing span group 100 that comprises that 4 swing spans 3 form, end in described swing span group 100 is provided with motor 1, also is provided with motor 1 at the other end of swing span group 100.

Referring to Fig. 2, be fixed with bearing 7, one drum drive axles 5 in the described swing span 3 and be arranged in the swing span 3 and be fixed on the inner ring of bearing 7, motor 1 has an output shaft 10, and the output shaft 10 of motor is captiveed joint with drum drive axle 5 by connecting shaft cover 4.

Referring to Fig. 3 to Fig. 5, be respectively arranged with the first groove 41 and the second groove 40 in drum drive axle 5 and output shaft 10 correspondences on the described connecting shaft cover 4, described output shaft 10 is connected and fixed in the second groove 40 by key, and described drum drive axle 5 is connected and fixed in the first groove 41 by key.And the sidewall at connecting shaft cover 4 offers tapped bore 42, described tapped bore 42 and the first groove 41 are communicated with, establish bolt 420 described tapped bore 42 interior twisting, described bolt 420 leans drum drive axle 5, fixes so that drum drive axle 5 and 4 in connecting shaft cover form failure-free.

During use, by the motor horsepower output at two ends, drive the rotation of cylinder 2 by connecting shaft cover 4 and drum drive axle 5, mode with respect to the one-sided motor horsepower output of tradition, power demand demand to motor is less, thereby has reduced the volume of required motor, and has reduced productive costs.
