Abstract
The utility model relates to a gear rack driving mechanism used for a crane carriage of a portal crane and belongs to the field of cranes. Front wheels and back wheels on two sides of the crane carriage press two wheel tracks correspondingly, two rack tracks and the two wheel tracks are fixedly connected with two main beams in parallel, two speed change motors are symmetrically installed on the lower portion of the crane carriage, and a driving gear connected with the output end of a speed reducing motor is meshed with the rack tracks correspondingly and moves along the rack tracks under drive of motor power to enable the four-wheel carriage to move along the wheel tracks. The gear rack driving mechanism provides large driving force required by working of the crane carriage, ensures large acceleration speed in starting, and improves working efficiency. For example, the gear rack driving mechanism is capable of effectively preventing natural sliding of the crane carriage caused by the fact that a ship body is inclined due to stormy waves when the gear rack driving mechanism is used for a ship portal crane, enables the crane carriage to work stably, efficiently and accurately under the work condition of large acceleration speed and comprehensively improves walking speed and stable performance of the crane carriage.
Description
Technical field
The utility model relates to a kind of gear-rack drive mechanism for the transfer crane crane carriage, belongs to the hoisting crane field.
Background technology
At present, the crane carriage on the transfer crane is generally roller driving and two kinds of forms of winch traction drive.The transfer crane of general land work, because foundation structure is stable, crane structure and ground are connected, and generally also are stable state, therefore two kinds of drive forms can both satisfy job requirements.Yet for gantry crane on board, because operating environment is special, can cause hull to produce certain angle of heel (reach as high as 5 °＜0.087rad 〉).Because and the coefficient of rolling friction between trundle and walking rails is very little, when angle of heel overpressure angle, carriage device will produce autokinetic movement, and this autokinetic movement that produces when work obviously is unfavorable for the complete machine operation.Obviously, roller drives with the winch driving and all can produce this autokinetic movement; In addition, in order to increase work efficiency, the traveling speed of transfer crane becomes larger, become run up time less, also so that the Acceleration of starting degree increases, only depend on force of rolling friction not provide and started required high acceleration, the demand of the obvious inapplicable high acceleration of type of drive of roller, and the winch mode of traction relatively relies on large spatial structure, and the limitation of himself is arranged.Therefore, be applicable to the driver train that transfer crane crane carriage high acceleration starts anti-heel in the urgent need to exploitation.
The utility model content
The purpose of this utility model provides a kind of gear-rack drive mechanism for the transfer crane crane carriage, autonomous heel motion when starting to overcome hoisting crane crane carriage high acceleration, thereby improve hoisting crane crane carriage stable working, particularity and work efficiency, and reduce the number of crane structure, reduce installing space.
The technical scheme that realizes the utility model purpose is as follows:
The utility model gear-rack drive mechanism, comprise girder, the four-wheel crane carriage, the crane carriage wheel rail, driven wheel, rack-track and change speed motor, article two, the crane carriage wheel rail is packed in two parallel girders, before the crane carriage both sides, the rear wheel correspondence is pressed on two wheel rails, article two, rack-track is corresponding parallel affixed with two girders respectively with two wheel rails, and two change speed motor symmetries are installed on the crane carriage bottom, is connected to the driven wheel engagement corresponding to the bar rack-track of reducing motor mouth, motor power orders about driven wheel and moves along rack-track, and lorry is moved along wheel rail.
Above-mentioned two rack-track correspondences are set in parallel in two wheel rail inboards.
Two change speed motor symmetries that above-mentioned symmetry is installed on the crane carriage bottom are positioned at the inboard of two rack-tracks.
Technological merit:
The utility model hoisting crane crane carriage adopts the pinion and-rack actuating device, can provide crane carriage work required larger propulsive effort, larger acceleration/accel when guarantee starting, increase work efficiency, can effectively prevent crane carriage because the natural slippage that alist produces makes crane carriage work traveling steadily accurate.When for example being used for gantry crane on board, the design's rack-and-gear device can make crane carriage effectively resist boats and ships because of naturally sliding that the stormy waves heel causes, make crane carriage under the high acceleration working condition requirement steadily, efficiently, accurately operation, General Promotion crane carriage traveling speed and stationary performance.The design's compact conformation, required installing space is very little, and incremental loading is very little.

Fig. 2, the utility model crane carriage drive birds-eye view;
The specific embodiment
How existing accompanying drawings the utility model is implemented:
In the utility model gantry crane on board crane carriage gear rack actuating device, such as accompanying drawing 1, shown in 2, two girders 1,1 ' and hull be connected, article two, wheel rail 2,2 ' is fixedly mounted on two crossbeams 1,1 ', article two, rack-track 6,6 ' symmetrical parallel are arranged on two wheel rail 2,2 ' inboards and captive joint with two crossbeams 1,1 ' respectively, the forward and backward wheel 7,8 of crane carriage 4 one sides is pressed on the wheel rail 2, and the forward and backward wheel 9 of crane carriage 4 opposite sides, 10 is pressed on the wheel rail 2 '; Two change speed motoies 3,3 ' symmetries are fixed in crane carriage 4 bottom vehicle frames, be positioned at two rack-track 6,6 ' inboards, change speed motor 3,3 ' mouth are connected with driven wheel 5,5 ' respectively, change speed motor 3,3 ' driven wheel 5,5 ' move along two rack-tracks 6,6 ', thereby four wheels that drive crane carriage 4 can start with high acceleration along wheel rail 2,2 ', the high-speed smooth operation.
