Abstract
The invention relates to an automatic leveling control system, which is designed for a small boat collecting and releasing device with double hoisting points. The two hoisting points are controlled by two identical winches. The automatic leveling control system has a manual mold and an automatic mold, a universal handle operation priority of the manual mode is higher than the automatic mode, and errors can be adjusted at any time when in the automatic mode. Counters are arranged at ends of the winches, whether the two hoisting points are horizontal or not is confirmed by the aid of values of the counters, and when the system detects that the values of the counters are identical after an automatic button is pressed down, the two hoisting points are lifted automatically. Limiting switches with identical limiting quantities are disposed at upper limiting positions, and accordingly accumulative errors are eliminated.
Description
(1) technical field
The present invention is two suspension centre canoe draw off gear design-calculateds, guarantees that two suspension centres keep the auto leveling control system of equal height in the folding and unfolding process.
(2) background technology
In the hoisting large-size jolly boat; Single suspension centre canoe draw off gear can't guarantee the stationarity of jolly boat, thus need to adopt the form of two suspension centres, but two suspension centre canoe draw off gear; In the retractable process; Will be through the height that keeps two suspension centres the identical level that guarantees jolly boat, control the canoe draw off gear of two suspension centres respectively for the multiple twin car, the level that whether can guarantee two suspension centres is to need a key problem in technology solving.At present, domestic also do not have an actv. levelling control system, and this has caused considerable restraint for safe handling of two suspension centre canoe draw off gears.
(3) summary of the invention
In order to address the above problem, guarantee the level of synchronization property of two suspension centres of two little boat and box handling gears of suspension centre, improve the safety in the use, the present invention has designed a kind of new auto leveling control system.It is realized through following technical scheme: adopt two identical passive type hydraulic wave compensation winches; It is identical all the time to make HM Hydraulic Motor offer the hydraulic oil discharge capacity of two winches through the control cock in the loop; Identical to guarantee two winch rotating speeds, thus guarantee two suspension hook synchronization liftings.This winch is provided with two kinds of operation modes: play the ship pattern automatically, manually play the ship pattern.The operator is through rising ship operation mode two-way choice switch and can select to rise automatically the ship pattern or manually play the ship pattern on the operating console.Automatic mode detects whether level of two suspension centres through winch end counting machine.The priority that manually plays the ship pattern is higher than the ship pattern that rises automatically, in use, can carry out levelling through manually playing the ship pattern if find error, and limit switch stops lifting process automatically when rising to upper limit position.Because the spacing amount that the limit switch of two winches is provided with is identical, therefore when stopping ship, can thoroughly eliminate the non-equilibrium accumulated error in the lifting process, make ship reach complete equilibrium.
The advantage of this invention is: the auto leveling performance of two suspension centres is strong; Can in time eliminate when in the folding and unfolding process, finding error through manual operation; Manual operation is the preferential selection mode of system, can in time regulate the level attitude of canoe, simultaneously; When being promoted to the upper limit position, can thoroughly eliminate error through limit switch.
(4) specific embodiment
Adopt two identical passive type hydraulic wave compensation winches among the present invention; It is identical all the time to make HM Hydraulic Motor offer the hydraulic oil discharge capacity of two winches through the control cock in the loop; Identical to guarantee two winch rotating speeds, thus guarantee two suspension hook synchronization liftings.This draw off gear has and automatically plays the ship pattern and manually play the ship pattern, and the operator is through rising ship operation mode two-way choice switch and can select to rise automatically the ship pattern or manually play the ship pattern on the operating console.
When manual control played ship, behaviour ship person made the ship operation mode select switch of controlling on the vertical platform that rises to manual mode, available each control step of handle control.When receiving ship, operating handle has been pulled the ship position, and two winch synchronous same-speed rotations hoist; Make ship break away from the water surface; Operating handle makes the ship leveling again, and leveling is to pull to the side through handle to let the low suspension hook winch fast rotational in position, and the high winch of another suspension hook rotates at a slow speed.After the ship leveling, behaviour's ship person handle is pulled to the dead ahead with fast run location, and two winches begin the synchronous same-speed operation, upwards mention ship, up to being raised to end position, stop to finish lifting process automatically through limit switch.
When rising the ship manipulation automatically, adopt the button form.Two winch ends are provided with counting machine, calculate length of steel wire rope through the number of turns of calculating the cylinder rotation.The priority of universal handle is higher than a ship button automatically, is playing the error that can adjust two suspension centres in the ship process through universal handle automatically.Press automatically play the ship mode button after, Circuits System can detect two counter values, when two counter values are identical, just during the identical canoe level of rope capacity, play the ship function automatically and realizes immediately, carries out fast lifting.When ship hoist put in place after, stop lifting process automatically through limit switch.Because the spacing amount that the limit switch of two winches is provided with is identical, therefore when stopping ship, can thoroughly eliminate the non-equilibrium cumulative errors in the lifting process, make ship reach complete equilibrium, rise the ship process automatically and finish.
Claims (2)
1. the present invention is two suspension centre canoe draw off gear design-calculated auto leveling control system; Use two identical two suspension centres of hydraulic wireline winch control; It is characterized in that: have manually and automatic two kinds of patterns; Utilize counting machine to detect when two suspension centres are up to the standard and promote, manual mode can be adjusted error at any time, and limit switch is eliminated cumulative errors when being promoted to terminal point.
2. manual and automatic operation mode according to claim 1, it is characterized in that: the priority of manual operation mode is higher than automatic operation mode, can be implemented in the automatic operating process and eliminates error through M/C at any time.
