Abstract
The utility model relates to an automatic retraction device for a cable, which is composed of a pressure reducing valve, an overflow valve, an electromagnetic reversing valve, a motor, a winding drum with a revolving hydraulic joint, an oil cylinder, a flexible pipe, etc., wherein the oil cylinder and a lifting hook component are connected into integration, and the oil cylinder simultaneously moves with a heavy; the winding drum which is used for winding the flexible pipe, is connected with one end of the flexible pipe and is provided with the revolving hydraulic joint, and the motor are formed into a whole, and the winding drum, the motor and other relevant hydraulic elements are all fixed on the lifting arm of the first segment; the flexible pipe is connected between the winding drum with the revolving hydraulic joint and the oil cylinder. When the utility model is used for lifting the heavy, the maximum pressure of hydraulic oil of the motor is inputted, and the utility model obtains the double control of the pressure reducing valve and the overflow valve simultaneously to realize the free adjustment of the length of the flexible pipe (the cable) within the range of the permissive pulling force of the flexible pipe (the cable). When the heavy falls down, the motor and the winding drum with the revolving hydraulic joint are dragged to rotate. The overflow valve which plays the damping function is connected into a hydraulic oil discharging loop in series to prevent the flexible pipe from being released too long because of the inertia of moving components.
Description
Technical field
The utility model relates to weight lifting and implements the cable of electronic monitoring or flexible pipe that relevant Hydraulic Elements are handled during retractable, guarantee the device that suffered tension variations is very little, particularly be suitable for the occasion of the arm-type hoisting crane of multi-joint telescoping or the cargo height extra-high-speed that promotes.Because the power of this device is taken from the hydraulic pressure energy, fundamentally broken away from the obviously uneven drawback of wind spring application force, the operating mode that the weight lifting altitude is high more, the preceence of this device also just shows outstanding.
Background technology
At present, the hawser of subsidiary, tubing folding and unfolding actuating device on the common weight-lifting equipment, the mechanical energy of mostly utilizing wind spring to store is power, and such apparatus structure is simple, installs, safeguards very convenient, and different structure is seen everywhere.
If the hoisting depth extra-high-speed of institute's hoisting heavy is that the device of power is just powerless with the wind spring structure often, because the range of use of this device directly is subjected to the restriction of number of spring coils.The radial dimension of its structure can increase along with the increase of number of spring coils.And the pulling force that acts on the hawser (pipe) is the function of wind spring rotating cycle; the degree of difference also can increase along with the increase of number of spring coils between maximum and the minimum value; the situation that this structure can't be used at all appears in the condition following time regular meeting long and thin at hawser (pipe).
Summary of the invention
The purpose of this utility model provides a kind of easy to use, compact conformation, guarantee the accurate permanent pulling force automatic retraction device of hawser of weight stressed variation of hawser (pipe) in the overall process that promotes very little (the thing intensity one rule pulling force of tension can be adjusted thereupon, equates with one deck cable stress on the reel).
The purpose of this utility model is achieved in that by fuel inlet fitting, reducing valve, by pass valve, solenoid directional control valve, motor, have the reel that turns round hydraulic joint, oil cylinder, flexible pipe, back leakage connection is formed, be connected with between the oil cylinder and first motor and have the reel that turns round hydraulic joint, be connected with first by pass valve between two hydraulic fluid ports of first motor, the oil inlet of first solenoid directional control valve is connected with the oil outlet of first motor, be connected with second by pass valve between the return opening of first solenoid directional control valve and the fuel tank, second by pass valve and have between the reel that turns round hydraulic joint and be connected with solenoid directional control valve, be connected with reducing valve between first solenoid directional control valve and the motor, be connected with the 3rd by pass valve between reducing valve and the solenoid directional control valve, the 3rd by pass valve, reducing valve and fuel tank are connected, and the oil inlet of motor is connected with fuel tank.
Have the reel that turns round hydraulic joint and connect first motor by flexible pipe.
Be connected with back leakage connection on the fuel tank, be connected with fuel inlet fitting on the motor.
Oil cylinder and load hook parts fuse and are synchronized with the movement with weight, the reel and the groups of motors of twining flexible pipe and linking to each other with the one end are integral, all be fixed on the first segment crane arm together with other relevant Hydraulic Elements, flexible pipe is connected in and has between the reel and oil cylinder that turns round hydraulic joint.
During installation, at first oil cylinder is fixed on the hanger components of weight-lifting equipment; First motor, the reel that is tied with flexible pipe are installed in the side of first segment crane arm front end; As required reducing valve, three by pass valves, two solenoid directional control valves and corresponding pipeline, joint are installed concentratedly on suitable flat board and formed plate member, and be installed in first segment crane arm afterbody and motor ipsilateral; Use corresponding pipe joint and flexible pipe at last, finish between fuel inlet fitting, back leakage connection, plate member, motor, the oil cylinder and with being connected of weight-lifting equipment associated pipe.
The utility model has the advantages that at multi-stage telescopic arms, especially replace wind spring mechanism on the weight-lifting equipment of super-tonnage; Reel is discharging or is rolling in the flexible pipe process, and hawser (pipe) is under suffered pulling force substantially constant state, according to rotating freely of the length realization reel of actual needs.Be specially adapted to the long and thinner occasion of diameter of hawser (pipe) release distance.Compact conformation, reliable in action, for the hawser (pipe) of different-diameter and intensity, the folding and unfolding pulling force is arbitrarily adjustable, and prolonged service life.
Be described further below in conjunction with drawings and Examples.
