Abstract
The utility model provides a mechanical-hydraulic combined winding device and relates to a winding device for engineering machinery. The mechanical-hydraulic combined winding device is characterized in that a bearing seat is installed on a rack. A winding drum main shaft is fixed on the bearing seat. A winding drum and a driving main gear are installed on the winding drum main shaft. An external contacting brake is disposed on the winding drum. A double internal expanding clutch is disposed in the winding drum. At least two hydraulic motors and reducers with the same number as the hydraulic motors are arranged below the winding drum in the rack. Pinions disposed at output ends of the reducers are meshed with the main gear. Each motor is provided with a bidirectional balance valve. Through adoption of the structure, the mechanical-hydraulic combined winding device can achieve functions of falling loads of power and free hook-falling. The double internal expanding clutch is disposed in the winding drum, double motors and double reducers are used for driving the main gear on the winding drum to work, and therefore a whole machine operates stably, hoisting capacity of the whole machine is large, hoisting speed of the whole machine is high, and working efficiency of a dynamic consolidation machine is greatly improved. If larger hoisting capacity is needed, three sets or four sets of reducers and motors can be adopted to drive.
Description
Technical field
The utility model relates to a kind of construction machinery and equipment and uses winding plant, specifically, and the winding plant of using about equipment such as crawler crane, rubber tired crane, dynamic compaction machinery, continuous wall grabs.
Background technology
As everyone knows, hoisting mechanism generally is used in the elevator machinery field, and construction machinery and equipment generally is that the built-in hoisting speed reducer of motor driven drives reel work with hoisting mechanism; Normally single motor list reductor structure; This compact conformation, saving space, shortcoming is that lifting capacity is big inadequately, is not easy to realize free off the hook function; If adopt the free off the hook reductor of import cost very high, this structure is lacked service life on the dynamic compaction machinery; Another kind of structure is mainly to be used on the dynamic compaction machinery; By driving engine direct drive drop-gear box; Miniature gears on the output shaft of drop-gear box is meshed with big gear wheel on the drum shaft and drives reel work, and reel adopts single internal expanding power-transfer clutch, single external brake; This structure difficult installation, lifting capacity be big inadequately, it is bigger to take up room, and cost is higher, can not realize that power transfers the function that does not promptly have hoisting crane.
Summary of the invention
In order to solve the technical matters of above-mentioned existence, the utility model provides a kind of lifting capacity big, the fast mechanical-hydraulic convolution of hoisting speed winding plant.
The purpose of the utility model realizes through following technical proposals: mechanical-hydraulic convolution winding plant; Installation shaft bearing on frame; Spool spindle is fixed on the bearing seat, reel is installed on spool spindle and is driven big gear wheel, on reel, is provided with external brake; It is characterized in that: in reel, be provided with two internal expanding power-transfer clutchs; In frame, the below of reel is provided with the reductor of at least two HM Hydraulic Motors and respective numbers, and the miniature gears while of reductor mouth meshes with the big gear wheel on the spool spindle.
The beneficial effect of the utility model: the utility model adopts said structure, can realize the power below, also can realize free off the hook function.Through two internal expanding power-transfer clutchs are set in reel, adopt the two reductors of double motor to drive, the big gear wheel work on the drum shaft, complete machine operates steadily, and hoisting capacity is big; If require hoisting capacity bigger, also can adopt three cover or quadruplet reductor motor driven.The utility model mechanical-hydraulic convolution winding plant hoisting speed is fast, is used on the dynamic compaction machinery, can improve the work efficiency of dynamic compaction machinery greatly.

The specific embodiment
Mechanical-hydraulic convolution winding plant; Installation shaft bearing 3 on frame 1, spool spindle 5 are fixed on the bearing seat 3, and reel 2 and big gear wheel 8 are installed on spool spindle 5; On reel 2, be provided with external brake 7; In reel 2, be provided with two internal expanding power-transfer clutchs 6, in frame 2, the below of reel 2 is provided with two HM Hydraulic Motors 10 and two reductors 9.Bidirectional balanced valve 4 is installed on each motor 10.
The principle of work of the utility model: pressure oil CD-ROM drive motor 10; HM Hydraulic Motor 10 drive speed reducer 9; Miniature gears on the speed reducer output shaft drives the big gear wheel 8 on the spool spindle; Internal expanding power-transfer clutch 6 makes its work through hydraulic oil, realizes the rotation work of reel, and then the lifting of realization weight is transferred; When suspension hook (no weight) in the above, if internal expanding power-transfer clutch 6 quits work, suspension hook just can be realized free off the hook function, can be through the lowering velocity and the height of external brake 7 control suspension hooks; If internal expanding power-transfer clutch 6 is in running order always; Change the rotation direction of HM Hydraulic Motor 10 through the hydraulic oil change-over valve; Just can realize that power transfers, each HM Hydraulic Motor 10 all is equipped with bidirectional balanced valve 4, and every reductor 9 carries the non-maintaining drg of normally closed that hydraulic pressure discharges; Can improve deceleration and stopping performance, improve the mechanical movement reliability.
