Description
Technical field
The utility model relates to a kind of maintenance tool for aircraft floor workbench lifting locomotive, and specifically the utility model relates to a kind of control setup that locomotive work lifting platform locomotive carries out speed function action operated in conjunction of controlling.
Background technology
China Engineering Mechanical Industry Association on February 15th, 2006 at Beijing evaluation meeting disclosed High Above Ground Work Platform Factory, Beijing Crane Factory two GTBY22S type boom type high-altitude operation platform and GTWY20 type column type overhead operation platform product.Its high-altitude operation platform mainly is made up of structure division, electric system, hydraulic efficiency pressure system.All mechanical actions promote to finish by hydraulic actuating cylinder or HM Hydraulic Motor.Because they can only move voluntarily, therefore there is not the alerting ability of motor-driven control speed combination under line traffic control.And present high-altitude operation platform of the prior art mostly is the speed of electronic each action of line traffic control and control action greatly, and can not normal operation and control under power free situation.For the dorsal fin of larger radius of curvature, the wing of big span span, the vertical fin that straight in length and breadth height space is big, horizontal tail obstacle arrive at maintenance platform lifting locomotive, the lifting service work meeting that regular dismounting is safeguarded brings many inconvenience.Normal operation under the particularly passive situation and control will take place to stop work and treat electricity, nearly the problem of missing opportunity of combat and normally sailing.
Because locomotive work flat-bed parts can be because of the electronic too fast mechanical accident that easily produces near the aircraft parts time.Actual needs according to the ground maintenance work of aircraft; each function action of locomotive work flat-bed; all needing fast slow motion combines; each action of manual control; guarantee that the locomotive work platform can normal operation under power free situation and the locomotive work platform accident that in use can not meet accident.Therefore realize its corresponding manually with just seem necessity of ten minutes of electric functions.
Summary of the invention
The purpose of this utility model provides a kind of flexible to operation, and it is operated in conjunction to carry out speed according to actual needs, but each function action of manual control, even under the non-transformer situation, two control switching mechanisms that the locomotive work platform also can normal operation.
The technical solution that its technical matters that solves the utility model adopts is: the two control of a kind of locomotive work platform locomotive switching mechanism, comprise locomotive work platform locomotive body and with respect to the chassis side folding and unfolding and be movably connected on staying pin and being supported in ground-surface workplatform carrier base plate of chassis by the folding and unfolding strut, it is characterized in that, be equipped with on the described workplatform carrier base plate bevel drive mechanism that is series at the speed governing speed reduction gearing and with bevel drive mechanism be coupled to each other crane electronic with manually operated switching mechanism and manual rocking-turn mechanism, manually operated switching mechanism and bevel drive mechanism combine and assemble are on the base plate plane of flat-bed carrier inner chamber; Be provided with at manual rocking-turn mechanism and the joining position of retarder mechanism can with motor drive mechanism switch mutually at any time manually and electronic change-over swith, pass through the manual rocking-turn mechanism and the driving chain of separate connection separately respectively thereby form, transmission shaft drives the manual of bevel drive speed governing retarder composition, the two control transfer devices and the hand of the lifting of electronic control crane, two control transfer devices of the first half revolution action of electronic controlling and driving locomotive work Platform Implementation locomotive original place rotation, and by connection pipe fitting, the be connected in series fuel priming pump of platform hydraulic of locomotive system of change-over swith and electromagnetic valve, the sequence valve of each hydraulic ram expanding-contracting action of manual control form manually, two control transfer devices of each hydraulic ram expanding-contracting action of electronic control.
The utility model is as follows than the beneficial effect that prior art has.
Electronic and the hand gear of locomotive work flat-bed that the utility model provides can be finished locomotive work flat-bed everything.After equipment moves to desired location, provide power with manual hydraulic oil pump.Rotation change lever places manual position, and the rotary handle of manpower rotation hand-operated mechanism carries out transmission by hand gear, drives the speed governing retarder and rotates, and gives swing type mechanism by the transmission of speed governing retarder again, and swing type mechanism drives the original place rotation of workplatform.When manual rotary handle clockwise rotated, all above at the bottom of locomotive work flat-bed parts clockwise rotated; When manual rotary handle rotated counterclockwise, all above at the bottom of locomotive work flat-bed parts rotated counterclockwise.Crane change lever places manual position, the manual rotary handle of manpower rotation hand-operated mechanism, carry out transmission by hand gear, the drive retarder rotates, and gives the crane runner by the retarder transmission again, and the rotation of crane runner drives crane rope and carries out folding and unfolding, thereby realize the oscilaltion of crane hook, realize the lifting goods, the lifting weight can carry out shut-down operation in any position of vertical dimension, and the maximum height of hoist lifting hook can reach 7000mm; When manual rotary handle clockwise rotated, locomotive work flat-bed crane parts were done the action that raises; When manual rotary handle rotated counterclockwise, locomotive work flat-bed crane parts were made down maneuver.
The utility model provides locomotive work flat-bed hand gear; no matter enlarged the locomotive work flat-bed and used category, be under situation about having a power failure, or under power free situation; all can normally be carried out to guarantee engineering maintenance work with manually carrying out work.Simultaneously, the workplatform that hand gear has been arranged, make the locomotive work flat-bed more convenient to operate flexibly, it is operated in conjunction to carry out speed according to actual needs, locomotive work flat-bed parts have been solved the time near the aircraft parts, because of the electronic too fast mechanical accident that easily produces, the safety of locomotive work flat-bed is improved greatly, has fully satisfied ground maintenance personnel's operating needs.
