Due to the adoption of the constant tension wave compensation device, on the premise of not improving the rotating speed of the large-load lifting winch, the problems of low lifting speed caused by high rope winding multiplying power and large reduction ratio of the movable pulley block, and high difficulty on adapting to operation under the marine working conditions can be rapidly responded and solved.
Description
One, technical field
The utility model relates to the compensation of undulation device of a kind of ocean hoisting crane, and particularly heavy ocean hoisting crane carries out compensation of undulation to select the best lifting device on opportunity before hoisting.
Two, background technology
Present ocean hoisting crane compensation of undulation technology is only to use the single winch that hoists, and by the hoist state of kinematic motion of winch of control, makes its motion along with wave carry out the folding and unfolding cable automatically, realizes the compensation of undulation function.Because the live load of heavy ocean hoisting crane under non-compensation of undulation operating mode is big, must adopts running block to restrict more and twine to reduce the pulling force of single wire rope.For reaching specified lifting velocity, just the hoist rotating speed of winch of the single rope speed of steel rope is inevitable very high.If also need take into account the operating needs of the quick response of compensation of undulation, then the rotating speed to the winch that hoists proposes higher requirement.And heavy load, the high-revolving winch design difficulty that hoists are very big, the productive costs height.
Three, summary of the invention
Goal of the invention of the present utility model is carried out quick compensation of undulation to select the best lifting permanent tension force wave compensating device on opportunity before being to provide a kind of heavy ocean crane hoisting, carry out at the rotating speed of the winch that need not heavy load hoisted that improved can to respond solution fast under in advance slow because of running block wiring multiplying power height, the big caused lifting velocity of reduction ratio, be difficult to adapt to the open ocean shop problem.
This permanent tension force wave compensating device, it is characterized in that it comprises the main winch that hoists, the selftenssion winch that the main winch cable that hoists passes wherein running block, plugs into the main winch cable other end that hoists, be positioned at the brake system on the selftenssion winch reel baffle plate, with selftenssion winch power input shaft bonded assembly drop-gear box, by drop-gear box and selftenssion winch bonded assembly hydraulic executing system and by circuit respectively with hydraulic executing system and the permanent tension force logical signal of brake system bonded assembly disposal system.
Owing on the main winch cable other end that hoists has been plugged into a high-revolving selftenssion winch and the reel baffle plate at selftenssion winch, be equipped with brake system, utilize the high speed performance of selftenssion winch to remedy the loop wheel machine master slow defective of hoisting of winch that hoists, guarantee under permanent tension state, to receive when loop wheel machine rises and fall on the waves rope or put rope, realize the compensation of the relative position of weight and boats and ships, the rotating speed of the main like this winch that hoists does not need to improve.
Four, description of drawings
Accompanying drawing is the structural representation of the permanent tension force wave of the utility model compensating device.
Five, the specific embodiment
Below in conjunction with accompanying drawing permanent tension force wave compensating device structure of the present utility model is described further.
As shown in drawings, be applied in the heavy ocean loop wheel machine of marine operation, in order to be implemented in lifting work under the severe sea condition, must on hoisting system, be equipped with permanent tension force wave compensating device, to eliminate the boats and ships that wave causes and the relative motion of weight 4, weight 4 can arbitrarily rise and drop to positive and negative 3m scope, and the permanent tension force of suspension hook can be adjusted as required.
The permanent tension force wave of the utility model compensating device comprises selftenssion winch 1, brake system 2, the main structures such as winch 3, running block 5, hydraulic executing system 6, permanent tension force logical signal disposal system 7, drop-gear box 8 that hoist.Wherein the structure of the steel wire penetrating running block 5 of the main winch 3 that hoists, the main winch 3 employing running blocks 5 that hoist makes stressed being minimized of single rope to solve high to the steel rope requirement of strength greatly problem of heavy ocean hoisting crane load; Plug into selftenssion winch 1 in main winch 3 steel wire penetrating running blocks 5 backs that hoist, selftenssion winch 1 is high speed winch, the reel baffle plate of selftenssion winch 1 is provided with brake system 2, brake system 2 is a High Performance, big braking force, rapid-action chuck stopper, for selftenssion winch 1 provides enough braking forces, the selftenssion winch 1 brake safety when guaranteeing main winch 3 work; Hydraulic executing system 6 is connected with the power input shaft of selftenssion winch 1 by drop-gear box 8, permanent tension force logical signal disposal system 7 by circuit respectively with hydraulic executing system 6 and brake system 2 bonded assemblys, by controlling to realize modulated pressure actuating system 6 and brake system 2, make selftenssion winch 1 and the main winch 3 that hoists reach the purpose of orderly work to being installed on hydraulic executing system 6 and brake system 2 electromagnetic valve everywhere.
Because the main winch 3 that hoists has adopted running block 5, though stressed being minimized of single rope, but speed has also reduced simultaneously, slow in order to overcome the big caused lifting velocity of wiring multiplying power height, reduction ratio that adopts running block 5 to bring, compensating weight 4 is with respect to the problem of the motion of boats and ships fast, adopt high-revolving selftenssion winch 1 to be installed in the method for the other end of main winch 3 steel ropes that hoist, utilized the high speed performance of high speed selftenssion winch 1 to remedy the hoist above-mentioned defective of winch 3 of loop wheel machine master.
By permanent tension force logical signal disposal system 7 (this system is by the solenoid control hydraulic work system), control the tension function of selftenssion winch 1, coordinate the action relationships of selftenssion winch 1 and the main winch 3 that hoists simultaneously, select weight 4 Heave Heres easily.At first start-up system obtains permanent tension function, and selftenssion winch 1 is transferred until lower limit, and the permanent tension force operation of winch is ready; Can operate main hook transfer to weight 4 places this moment, and hook allows selftenssion winch 1 be in permanent tension state, and steel rope links to each other with weight 4 with certain force of strain, guarantee to connect weight 4 and boats and ships steel rope be no more than specified pulling force, with the safety of guaranteeing that weight 4 lifts by crane.Selftenssion winch 1 rised and fell on the waves and received rope or put rope under the control of permanent tension force logical signal disposal system 7 this moment, realized the compensation of the relative position of weight 4 and boats and ships.When operation selftenssion winch 1, the main winch 3 that hoists will be ready; When boats and ships are in crest, cancel permanent tension force operation, selftenssion winch 1 will be by the chuck stopper drag of brake system 2, simultaneously, system will initiatively switch to the main state that hoists, this moment, suspension hook possessed with the power of setting and the trend of speed rising, and loop wheel machine can be with the command speed hoisting heavy.
