Abstract
The utility model relates to a master controller used for controlling the movement of lifting equipment. The handle of the existing master controller resets automatically via an extension spring or a torsion spring, and the entire size of a spring and the controller is overlarge with short service life. The master controller comprises two rotation shafts which are arranged on a bracket in cross shape. A handle is movably connected with the center of the rotation shafts at lower part and passed through the body of the rotation shaft at upper part. The end heads of the rotation shafts are fixed with segment gears, the segment gears are fixed with shifting blocks, two sides of the shifting blocks are symmetrically and movably provided with resetting shifting sheets, the resetting shifting sheets are movably connected with spring seats, and two ends of a resetting spring are sheathed with the spring seats. Gears on the top end of a transmission shaft in a contact system are correspondingly engaged with the segment gears on the rotation shafts. The master controller has compact structure, small volume and long service life.
Description
Technical field
The utility model relates to a kind of control setup, especially a kind of master controller that is used to control the weight-lifting equipment activity.
Background technology
Master controller is widely used in the control system of various mechanical equipments, especially in the lifting industry, by the comings and goings of master controller control hoisting crane.Master controller generally includes handle, driving device and omnipotent pole changer.Driving device adopts center cross, comprises the rotating shaft of two square crossings, and wherein the rotating shaft middle part above strides across following rotating shaft for arch, and has groove vertically at arcuate part.Handle is movably connected in the central authorities of a rotating shaft below the cross rotating shaft by hinge, and passes the groove of a top rotating shaft.Handle is the rotation of two rotating shafts of may command like this.Two rotating shafts that drive in the driving device by handle in the work are rotated, and driving device is controlled the closure of contact in the omnipotent pole changer again, thus the action of control hoisting crane.The handle of existing master controller is generally realized automatically reseting by extension spring or torsion spring, is called the utility model patent (patent No.: 02232355.4) disclose a kind of master controller that handle is resetted by extension spring of " the extension spring Bringing-back mechanism of hoisting crane control desk " as name.This master controller comprises support, and transmission device is the semiaxis that cross arranges through two groups and is arranged on the support body, and an end of semiaxis is provided with the Bringing-back mechanism that is made of extension spring etc., and control handle is equipped with at the center of transmission device.In use, the spring of extension spring structure and the drag hook easy fracture between support, extension spring and controller whole service life are short, and spring is pulled outwardly and causes usage space to strengthen simultaneously, has increased the overall dimensions of controller.Use the torsion spring structure can dwindle the overall dimensions of controller, but the structure of torsion spring itself cause spring short service life.
Summary of the invention
The purpose of this utility model is to solve short, problem such as overall dimensions is big in the service life that exists in the prior art, and a kind of master controller that handle is resetted by the stage clip structure is provided.
The utility model is to realize this purpose by following structure: comprise a square body support frame and handle, two rotating shafts are square crossing and are arranged on the support, and handle flexibly connects rotating shaft central authorities below, and passes the axis body of a top rotating shaft.The two ends of rotating shaft are fixed with quadrant gear respectively, are fixed with pulling block on the quadrant gear, and the bilateral symmetry activity setting of the shifting block plectrum that resets is connected with spring perch on the plectrum that resets, and the two ends of retracing spring are nested with on spring perch.The top of the transmission shaft of contact system is provided with gear, and with the corresponding engagement of quadrant gear in the rotating shaft.
Owing to adopted the stage clip structure, this master controller compact conformation, volume are little, and service life is longer.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of master controller comprises a square body support frame 1 and handle 5, and cross rotating shaft 6 is arranged on the support 1, and wherein the rotating shaft middle part above strides across following rotating shaft for arch, and has groove vertically at arcuate part.Handle 5 is movably connected in the central authorities of a rotating shaft below the cross rotating shaft by hinge, and passes the groove of a top rotating shaft.The two ends that constitute two rotating shafts of cross rotating shaft 6 are fixed with quadrant gear 3 respectively, be fixed with shifting block 4 on the quadrant gear 3, the bilateral symmetry of shifting block 4 is provided with two rotary plectrums 2 that reset, and is connected with spring perch 9 on the plectrum 2 that resets, and the two ends of retracing spring 10 are nested with on spring perch 9.The top of the transmission shaft 8 of contact system is provided with gear 7, and with rotating shaft 6 on quadrant gear 3 corresponding engagements.
During operating handle 5, handle 5 rotates by two rotating shafts that slide block control constitutes cross rotating shaft 6, drives quadrant gear 3 and rotates synchronously.Quadrant gear 3 rotates by the transmission shaft 8 that the gear 7 that is engaged with drives contact system, thereby realize the rotation of the cam bit on the transmission shaft 8, cooresponding contact head can be depressed or lift to the projection of cam bit and recess, make the contact close or close, and then closing or closing on the control hoisting crane circuit, realize control to the hoisting crane action.During handle 5 activities, shifting block 4 is movable thereupon, and shifting block 4 drives the plectrum 2 that resets and rotates, and makes the leftover bits and pieces of two plectrums 2 that reset close to the center, and retracing spring 10 just is compressed.Behind handle 5 tenth skills, retracing spring 10 flicks, and plectrum 2 and shifting block 4 reset handle 5 by resetting.
