Abstract

The utility model discloses a device capable of automatically controlling constant tension by using a hydraulic oil-way. The device comprises a hydraulic pump unit, a constant tension valve block and a hydraulic motor which are connected by oil pipes, wherein the constant tension valve block is arranged between the hydraulic pump unit and the hydraulic motor. The motor drives the hydraulic pump unit to pump oil out, the oil reaches to the hydraulic motor through a three-way pressure relief and a switching valve to drive the hydraulic motor to rotate, and the conversion between hydraulic energy and mechanical energy is realized by the motor, therefore the retraction and extension of a cable on a mooring winch can be automatically adjusted. The security risks that when a ship is moored in shore or cargoes are loaded or unloaded, the cable becomes tight or loose due to tidal fluctuations, and thus the cable snaps or the ship goes away from the pier can be eliminated.

Description

Permanent automatic tension control apparatus through hydraulic circuit
Technical field
The utility model belongs to marine anchor winch field, is specifically related to a kind of permanent automatic tension control apparatus of marine anchor winch.
Background technology
When boats and ships pulled in to shore mooring or handling goods, the draft of ship can be because tidal bulge falls or cargo handing changes, thereby the mooring cable that causes mooring winch on the ship becomes tight or fluffs.If hawser stretches tight very tightly, can cause hawser to snap, if hawser is too loose, can cause ship to float slipping from alongside, either way there is potential safety hazard, possibly cause safety misadventure.
The utility model content
The utility model purpose: the purpose of the utility model is the safety hazard that exists when boats and ships pull in to shore mooring or handling goods in order to solve, and a kind of device that can realize automatic constant tension control through hydraulic circuit is provided.
Technical scheme: a kind of permanent automatic tension control apparatus through hydraulic circuit; Described permanent automatic tension control apparatus comprises that through oil pipe bonded assembly hydraulic pump unit, permanent tension valve group and HM Hydraulic Motor described permanent tension valve group is arranged between hydraulic pump unit and the HM Hydraulic Motor.
Described hydraulic pump unit is connected to form by electrical motor, Hydraulic Pump and safety pump according to this.
Described permanent tension valve group is connected to form by three-way pressure reducing valve and change-over valve according to this, and described change-over valve links to each other with the entrance of HM Hydraulic Motor through oil pipe.
Beneficial effect: the utility model is simple and reasonable; Only need permanent tension force reversing handle is changed to the AUTO position from the NORMAL position; Constant tension device just can begin automatic work; When the utility model can prevent ship mooring or handling goods, thereby to cause hawser to break accidents caused because of the drinking water degree change of ship.
Description of drawings
Fig. 1 is the utility model hydraulic structure scheme drawing.
Fig. 2 is the structural representation of the permanent tension valve of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
A kind of permanent automatic tension control apparatus through hydraulic circuit, described permanent automatic tension control apparatus comprises that through oil pipe bonded assembly hydraulic pump unit 1, permanent tension valve group 2 and HM Hydraulic Motor 3 described permanent tension valve group 2 is arranged on hydraulic pump unit 1 draw
Between the HM Hydraulic Motor 3, described hydraulic pump unit 1 is connected to form by electrical motor 11, Hydraulic Pump 12 and safety pump 13 according to this.Described permanent tension valve group 2 is connected to form by three-way pressure reducing valve 21 and change-over valve 22 according to this, and described change-over valve 22 links to each other with the entrance of HM Hydraulic Motor 3 through oil pipe.
Open permanent tension force pump unit, hydraulic oil is got by oil pump, through permanent tension valve control; Reach HM Hydraulic Motor, drive HM Hydraulic Motor and rotate, when external force during greater than the mechanical resistance sum of the propulsive effort of HM Hydraulic Motor and winch; Motor begins counter-rotating, and winch is in the cable laying state, when external force during less than the difference of the propulsive effort of HM Hydraulic Motor and mechanical resistance; HM Hydraulic Motor just changes, and this moment, winch was in the state of drawing over to one's side.When external force was between these two power, it is motionless that motor keeps, and winch neither cable laying is not drawn over to one's side yet.This
Utility model is simple and reasonable, only needs permanent tension force reversing handle is changed to the AUTO position from the NORMAL position, and constant tension device just can begin automatic work.
When ebb tide/loading; Originally the hawser of tension fluffs gradually; At this moment the oil suction from fuel tank of electric motor driven Hydraulic Pump is discharged pressure oil from outlet, reaches the HM Hydraulic Motor import through change-over valve again through three-way pressure reducing valve output constant compression force oil; Drive HM Hydraulic Motor and miniature gears and rotate together, miniature gears passes to the hawser on the cylinder through big gear wheel, main shaft, cylinder with power.The motor inlet constant pressure, the mechanical resistance of winch is constant, and after motor overcame mechanical resistance, the winch power output was constant.When hawser gradually to the time less than the power output of winch, winch is drawn over to one's side hawser and is become gradually tightly and when identical with the winch power output, stop to draw over to one's side.
When rising tide/unloading, originally the hawser of tension becomes tighter.Permanent tension force pump group normal operation; External force is delivered to HM Hydraulic Motor with power from cylinder, main shaft, big gear wheel, miniature gears through hawser; The entrance pressure of motor increases, and three-way pressure reducing valve is in order to keep the constant beginning draining of constant pressure, the import counter-rotating winch cable laying of motor.Same existence owing to the winch mechanical efficiency, external force needs the mechanical resistance of customer service winch and motor driven power just can make the winch cable laying.When the power on the hawser has the mechanical resistance sum that overcomes winch greater than the propulsive effort of HM Hydraulic Motor gradually simultaneously, this moment the winch cable laying.Power on hawser equates to stop cable laying with this power.
To sum up when external force during greater than the difference of motor power output and winch mechanical resistance, less than motor power output and winch mechanical resistance sum, neither also not take-up of cable laying of winch.
