Abstract
The utility model relates to a kind of development machine, particularly relates to a kind of development machine eyelid retractor.Utility model comprises: supporting leg, base plate, and supporting leg and base plate are flexibly connected by joint pin.The utility model supporting leg lower plane is welded with joint pin, and spherical joint pin column cap matches with the spherical needling of base plate, base plate and cover plate are bolted together by four, in order to prevent coal ash from entering in needling, between cover plate and column cap, dust ring is housed.In order to contact with roadway floor, eyelid retractor base plate lower plane is welded with six footing.The utility model solves the problem of rear support portion eyelid retractor and base plate bad adaptability when development machine slope works inside coal mine roadway.Change original rigid support device structure into ball-type structure, add the degree of freedom of base plate, enhance the compliance of eyelid retractor to roadway floor, ensure that stability during complete machine cut.
Description
Technical field:
The utility model relates to a kind of development machine, particularly relates to a kind of development machine eyelid retractor.
Background technology:
Development machine belongs to Coal Mechanical equipment, it is the heading equipment of coal petrography of mechanically declining, be mainly used in the driving in colliery coal road, half-coal rock roadway, total rock lane, primarily of several large parts composition such as cutting units, shovel board portion, first conveyor, body, rear support portion, electrical system, hydraulic system, water circuit system, oil cylinder, there is the function such as cut, loading, transhipment coal petrography, atomizing de-dusting, certainly walking.
The work under bad environment of development machine, roadway floor is uneven, with a varied topography.General development machine service condition is longitudinal direction ± 18 o, side direction 8 o.Rear support portion is the critical piece of development machine, during development machine work, machine stress is complicated, especially when yaw cuts, machine bears very large lateral force and cut counter-force, and lateral force forms tilting moment, complete machine stability is poor, cut counter-force is moved after causing machine longitudinally, and rear support portion eyelid retractor is the vitals moved after stoping development machine longitudinally, eyelid retractor ground under the effect of rear support oil cylinder in rear support portion, reduce the vibration of body during cut, improve job stability and prevent body longitudinal sliding motion.So eyelid retractor is the critical piece ensureing complete machine stability, it is the key ensureing development machine performance.
Development machine inside coal mine roadway slope work time, the frictional force of roadway floor to machine not only wants balanced side force, also want the component that balancing gravity is downward on inclined-plane, the supporting leg of current domestic development machine eyelid retractor and base plate are and are rigidly connected or integrated formed structure, this structure is to the bad adaptability of roadway floor, can not ensure giving full play to of machine performance, time serious, machine cannot normally work.
Utility model content:
The utility model object is to provide a kind of development machine eyelid retractor, and this structure solves development machine problem of eyelid retractor bad adaptability during the work of slope inside tunnel, improves the stability of development machine when cut, effectively ensure that giving full play to of overall performance.
Technical solution:
The utility model comprises: supporting leg, base plate, and supporting leg and base plate are flexibly connected by joint pin.
Described base plate top be provided with can joint pin rotate spherical needling.
Described joint pin is made up of spherical column cap and connecting rod, and described connecting rod is fixedly connected with supporting leg, and spherical column cap is placed in spherical needling, and spherical column cap and base plate adopt mating spherical surfaces.
Described spherical column cap is limited in the spherical needling of base plate by bolt, cover plate.
Described base plate arbitrarily rotates around spherical column cap.
Between the spherical column cap of described cover plate and joint pin, dust ring is housed.
The utility model supporting leg lower plane is welded with joint pin, and spherical joint pin column cap matches with the spherical needling of base plate, base plate and cover plate are bolted together by four, in order to prevent coal ash from entering in needling, between cover plate and column cap, dust ring is housed.In order to contact with roadway floor, eyelid retractor base plate lower plane is welded with six footing.
The utility model solves the problem of rear support portion eyelid retractor and base plate bad adaptability when development machine slope works inside coal mine roadway.Change original rigid support device structure into ball-type structure, add the degree of freedom of base plate, enhance the compliance of eyelid retractor to roadway floor, ensure that stability during complete machine cut.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of Fig. 1.
Detailed description of the invention:
See Fig. 1-2, the utility model supporting leg 1, base plate 4, be provided with footing 5 bottom base plate 4,
The spherical needling that can be provided with joint pin 2 and rotate is arranged at described base plate 4 top, supporting leg 1 and base plate 4 are flexibly connected by joint pin 2, joint pin 2 is made up of spherical column cap and connecting rod, described connecting rod is fixedly connected with supporting leg 1, described spherical column cap is limited in the spherical needling of base plate 4 by bolt 6, cover plate 3, spherical column cap and base plate 4 adopt mating spherical surfaces, and base plate 4 arbitrarily rotates around spherical column cap.
In order to prevent coal ash from entering the stuck column cap of needling, affecting the rotation of needling, dust ring 7 is housed between cover plate 3 and spherical column cap.
The course of work: the eyelid retractor involved by the utility model, when inside coal mine roadway, slope works development machine, base plate 4 can rotate around the spherical column cap of joint pin 2, increase the contact area of base plate 4 and roadway floor, enhance stability of strutting system, can solve be rigidly connected at present eyelid retractor inside scraggly coal mine roadway slope work time bad adaptability, the problem that can not effectively support.
