Abstract

The utility model discloses a boardside roller enabling a framework oil seal to be dismounted conveniently. The boardside roller enabling the framework oil seal to be dismounted conveniently comprises a swaying frame and a skeleton oil seal, and the side wall of the swaying frame corresponding to the skeleton oil seal is provided with a fourth through hole. By arranging through holes at the corresponding positions to the skeleton oil seal on the swaying frame, thin sticks can stretch into the through holes and can conveniently push out the skeleton oil seal arranged inside the swaying frame, and the dismounting of the skeleton oil seal is very convenient.

Description

A kind of topside cylinder of outside framework oil seal convenient disassembly

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 outside framework oil seal convenient disassembly.

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, improve output and economic benefit, generally use on the fishing boat of China now.

The structure of tradition topside cylinder mainly comprises motor, swing span, cylinder.In swing span, be provided with the drum drive axle by bearing carrier ring, in the bearing bearing caused corrosion in order to prevent that seawater etc. from entering, generally all can be at bearing both sides mounting framework oil sealing, but outside framework oil seal dismounting inconvenience very.

Summary of the invention

For the deficiencies in the prior art, the utility model provides a kind of topside cylinder of outside framework oil seal convenient disassembly.

The utility model is achieved by following technical proposals: a kind of topside cylinder of outside framework oil seal convenient disassembly, comprise swing span and outside framework oil seal, and offer fourth hole on the sidewall of described swing span corresponding to the outside framework oil seal position.

In the technique scheme, preferred, described fourth hole is provided with four, and arranges symmetrically and evenly.

The utility model compared with prior art has following beneficial effect: by offering through hole at swing span corresponding to the sidewall of outside framework oil seal position, stretch into thin rod and can eject easily the outside framework oil seal that arranges, convenience very in through hole in swing span.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the structural representation of swing span among Fig. 1.

Fig. 3 is the partial enlarged drawing at A place among Fig. 2.

Fig. 4 is the left view of Fig. 2.

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 to Fig. 4, a kind of topside cylinder of outside framework oil seal convenient disassembly, comprise swing span 1, described swing span 1 once-cast forms, have easy to process, the plurality of advantages such as mechanical strength height, described swing span 1 rotary being arranged on the base 10 can be adjusted the position of swing span 1 as required freely.

The left side of described swing span from left to right offers the first through hole 4 successively, the second through hole 5 and third through-hole 6, and the aperture of described the first through hole 4 is greater than the aperture of the second through hole 5, the aperture of the second through hole 5 is greater than the aperture of third through-hole 6, also be, the junction of the first through hole 4 and the second through hole 5 has a step, and the junction of the second through hole 5 and third through-hole 6 goes out to have a step.Wherein be embedded with on the second through hole and be provided with bearing 7, one drum drive axles 8 in outside framework oil seal 2, the first through holes and pass successively the bearing 7 in the first through hole 4, outside framework oil seal 2 and the third through-hole 6 in the second through hole 5.

Offer fourth hole 3 at described swing span 1 corresponding to the sidewall of outside framework oil seal 2 positions.And described fourth hole 3 is provided with 4, uniformly at intervals on the sidewall of swing span.

When wearing and tearing appear in outside framework oil seal, when perhaps bearing failure need to be changed, when also namely needing demolition, bearing is removed, finally stay outside framework oil seal and be embedded at the second through hole, this moment, outside framework oil seal was difficult to transfer to from the second through hole because stressed nowhere.

Offer the mode of fourth hole 3 corresponding to the sidewall of outside framework oil seal 2 positions at swing span 1 by the utility model, during dismounting, only need by in fourth hole 3, passing into a thin rod, outside framework oil seal namely is ejected from swing span 1, operate convenience very, and can not affect the performance of topside cylinder itself.

The right side structure of the utility model swing span is identical with the structure in swing span left side, does not give unnecessary details one by one inferior.

Claims

1. the topside cylinder of an outside framework oil seal convenient disassembly comprises swing span (1) and outside framework oil seal (2), it is characterized in that: offer fourth hole (3) on the sidewall of described swing span (1) corresponding to outside framework oil seal (2).

2. the topside cylinder of a kind of outside framework oil seal convenient disassembly according to claim 1, it is characterized in that: described fourth hole (3) is provided with four, and uniformly at intervals on the sidewall of swing span (1).
