Abstract
The utility model provides a hydraulic winch constant-tension device for holding constant tension of steel wires of different traction mechanisms as mooring winches and towing engines, which is composed of a constant pressure variable pump 1, an overflow valve 2, a hydraulic motor 3 and a host 4 and the like, wherein the oil inlet 5 of the constant pressure variable pump 1 is connected with a coiling side oil port 6 of the hydraulic motor 3, the oil reflux port 7 of the constant pressure variable pump 1 is connected with a releasing side oil port 8 of the hydraulic motor 3, the overflow valve 2 is arranged between the coiling side oil port 6 and the releasing side oil port 8 of the hydraulic motor which is mounted on the host 4 via a transmission device. The hydraulic winch constant-tension device is full-hydraulic type, the tension can be set by an adjusting valve, to adapt the mooring winches and towing engines of different traction tonnages, and the hydraulic winch constant-tension device has simple and reliable structure and high response speed.
Description
(1) technical field:
The utility model relates to the device that a kind of steel rope that is used for various towing machines such as mooring winch, towing port keeps constant tension power, particularly a kind of hydraulic wireline winch constant tension device.
(2) background technology:
Having a kind of in the existing hydraulic wireline winch constant tension device is exactly electric, it responds to the size of steel wire rope tension by the pulling force sensor that is installed on the wire rope pulley bearing pin, and the PLC control system that becomes electric signal to transmit the tension force size conversion, send the action command of receiving rope, slack rope to electromagnetic proportional valve by the PLC system again, thereby keep steel rope to keep tensioning, constant tension.This plant automation degree height, to the induction sensitivity height of tension force, speed of response is fast.But it has used pulling force sensor, the PLC control system, and the proportion magnetic valve element, these elements generally rely on import, and its cost is quite high.The type device need be worked out independent PLC program, and this program has only the designer to understand under the situation of underground code, and commonality is poor; The device debugging, maintenance, all need change the PLC program, the commissioning staff need possess very high electrical control expertise and know program source code, and is difficult in maintenance, the maintenance cost height.
(3) summary of the invention:
Goal of the invention of the present utility model provides a kind of simple and reliable, the hydraulic wireline winch constant tension device that speed of response is fast.
Hydraulic wireline winch constant tension device of the present utility model is made up of constant pressure variable displacement pump, by pass valve, HM Hydraulic Motor, main frame etc.; The oil-feed port of constant pressure variable displacement pump is connected with the receipts rope action side hydraulic fluid port of HM Hydraulic Motor, the return opening of constant pressure variable displacement pump is connected with HM Hydraulic Motor slack rope action side hydraulic fluid port, by pass valve is installed between the receipts rope action side hydraulic fluid port and slack rope action side hydraulic fluid port of HM Hydraulic Motor, and HM Hydraulic Motor is installed on the main frame by driving device.
It is actv. that this hydraulic wireline winch constant tension device is received rope, and when steel rope was in the relaxed state tensile force and diminishes, the pressure oil of constant pressure variable displacement pump drove HM Hydraulic Motor and main frame rotated tighten up steel rope and make tension force recover constant; The slack rope of this device is passive, the tension force of steel rope converts the pressure of hydraulic efficiency pressure system to by HM Hydraulic Motor, when tension force surpasses design value, hydraulic system pressure also surpasses design value, hydraulic oil is back to constant pressure variable displacement pump from by pass valve, and main frame drags the passive down steel rope that loosens to make tension force recover constant the counter of steel wire rope tension.
This device is realized that winch automatically performs and is received the action of rope slack rope by the hydraulic power system of winch is controlled, and keeps constant-tension to keep steel rope, in tension all the time, and speed of response is fast.This device does not use pulling force sensor, the PLC control system, and elements such as proportion magnetic valve, and use hydraulic part purchasing on the market, and homemade performance, quality all can satisfy operating needs, and be simple and reliable for structure, and maintenance cost is low.
(4) description of drawings:
Accompanying drawing is the utility model hydraulic wireline winch constant tension device structural representation.
(5) specific embodiment:
Structure below in conjunction with description of drawings the utility model hydraulic wireline winch constant tension device:
This hydraulic wireline winch constant tension device is made up of constant pressure variable displacement pump 1, by pass valve 2, HM Hydraulic Motor 3 and main frame 4 etc., and main frame 4 can be any mooring winch or towing machine by fluid motor-driven, the permanent tension function of needs.This device is a full hydraulic, can determine element according to parameters such as the operation pressure of main frame 4, working flows when selecting hydraulic part for use, hydraulic parts such as constant pressure variable displacement pump 1, by pass valve 2, HM Hydraulic Motor 3 can be in buying on the market, and homemade performance, quality can both satisfy operating needs.The HM Hydraulic Motor 3 of this device is installed on the main frame 4 by driving device, the oil-feed port 5 of constant pressure variable displacement pump 1 is connected with the receipts rope action side hydraulic fluid port 6 of HM Hydraulic Motor 3 by oil circuit, the return opening 7 of constant pressure variable displacement pump 1 is connected with the slack rope of HM Hydraulic Motor 3 action side hydraulic fluid port 8, and by pass valve 2 is installed between the receipts rope action side hydraulic fluid port 6 and slack rope action side hydraulic fluid port 8 of HM Hydraulic Motor 3.
The pressure decision that pressure that the constant tension value of this device is provided by constant pressure variable displacement pump 1 respectively and by pass valve 2 are set.Constant pressure variable displacement pump 1 provides constant compression force to act on HM Hydraulic Motor 3, the tension value of steel rope when this constant pressure is initiatively received rope corresponding to this device can be realized initiatively receiving under the differential tension value situation rope by the pressure setting of adjusting constant pressure variable displacement pump 1 and make constant tension; The tension value of the steel rope the when setting pressure of by pass valve 2 installs passive slack rope corresponding to this is set the passive rope of putting that can realize under the differential tension situation by the pressure of adjusting by pass valve 2 and is made constant tension.
When main frame 4 loads change, can make the hydraulic efficiency pressure system setting corresponding by the delivery pressure of adjusting constant pressure variable displacement pump 1 and the setting pressure of by pass valve 2 with load, thereby same set of hydraulic wireline winch constant tension device can be used on the different main frames, and same main frame can not use same set of hydraulic wireline winch constant tension device simultaneously in load yet.
Claims (1)
