Abstract
The utility model relates to the important part of a coal mine roadway heading machine, specifically a driving device for gathering arm, which is used in the gathering device for blanking of the heading machine. The utility model is characterized in that the gathering arm is disposed on a shovel plate through a shaft; the drive mechanism of the gathering arm is a hydraulic cylinder; one end of the hydraulic cylinder is hinged to the shovel plate and the other end thereof is hinged to a push arm which is fixedly connected to a main shaft in a circumferential direction; the upper end of the main shaft is fixedly connected to the gathering arm in a circumferential direction. The utility model is advantageous in that the problem of many failures and difficult maintenance caused by the fact that the shovel plate material recovering mechanism of the prior art is driven by a decelerator or a hydraulic motor can be resolved; the structure is simple and reasonable; the maintenance is easy and the cost is low.
Description
Affiliated technical field
The utility model relates to the vitals of coal mine roadway development machine, is specially a kind of rake claw drive unit, and it is the gathering-device that is used for development machine shovel board blanking.
Background technology
At present, the shovel board receiving mechanism of development machine is mainly reductor or fluid motor-driven, these two kinds of driving mechanism structure complexity, many, the maintenance difficult of fault, cost height.
The utility model content
For simplified structure, reduce fault, the utility model provides a kind of rake claw drive unit, has solved that existing shovel board receiving mechanism is existed by reducer driving or fluid motor-driven that fault is many, maintenance difficult, a baroque difficult problem.
The technical scheme that the utility model adopted is:
A kind of rake claw drive unit, the rake pawl is installed on the shovel board by axle, and the driving mechanism of rake pawl is a hydraulic cylinder.
Described rake claw drive unit, an end and the shovel board of hydraulic cylinder are hinged, and the other end and the push arm of hydraulic cylinder are hinged, and push arm is circumferentially fixedlyed connected with main shaft, and main shaft circumferentially is fixedly linked with the rake pawl.
Described rake claw drive unit, this device is provided with bearing pin, hydraulic cylinder, push arm, main shaft and rake pawl, bearing pin is installed in the cavity of shovel board, the cylinder body end of hydraulic cylinder links to each other with bearing pin, the tailpiece of the piston rod of hydraulic cylinder links to each other with push arm one end, the push arm other end is connected with main shaft by spline, and main shaft is connected by spline between the pawl with rake.
Described rake claw drive unit, push arm, main shaft are installed in the drive seat, and drive seat is by being bolted on the shovel board.
The beneficial effects of the utility model are:
1, the utility model is respectively adorned a hydraulic cylinder in shovel board bilateral symmetry cavity, and hydraulic cylinder one end and shovel board are hinged, and the other end and push arm are hinged, and push arm is circumferentially fixedlyed connected with main shaft, and the upper end of main shaft circumferentially is fixedly linked with the rake pawl.During work, the hydraulic cylinder piston rod stretching motion is converted into push arm and the main shaft reciprocally swinging around main shaft self axis, thus main shaft drive the rake pawl the shovel board surface with the main shaft be between the fan section at center in reciprocating motion.
2, the utlity model has the rake jaw arrangement of Driven by Hydraulic Cylinder, it is rational in infrastructure, and simple structure has reduced fault, has reduced cost.
Description of drawings
Fig. 1 is the utility model structural layout plan in shovel board.Among the figure: 1 shovel board; 2 bearing pins; 3 hydraulic cylinders; 4 rake pawls; 5 push arms.
Fig. 2 is the utility model rake claw drive unit structural representation.Among the figure: 2 bearing pins; 3 hydraulic cylinders; 4 rake pawls; 5 push arms; 6 drive seat; 7 main shafts.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Shown in Fig. 1-2, rake pawl 4 is installed on the shovel board 1 by axle, and rake pawl 4 is symmetrical arranged, and the driving mechanism of rake pawl 4 is a hydraulic cylinder 3, and under the driving of hydraulic cylinder 3, rake pawl 4 can be around the axle reciprocally swinging.The utility model is respectively adorned a hydraulic cylinder 3 in shovel board 1 bilateral symmetry cavity, an end and the shovel board 1 of hydraulic cylinder 3 are hinged, and the other end of hydraulic cylinder 3 and push arm 5 are hinged, and push arm 5 is circumferentially fixedlyed connected with main shaft 7, and the upper end of main shaft 7 circumferentially is fixedly linked with rake pawl 4.
As shown in Figure 2, the utility model is the rake claw drive unit, and this device mainly comprises bearing pin 2, hydraulic cylinder 3, push arm 5, main shaft 7 and rake pawl 4.Bearing pin 2 is installed in the cavity of shovel board 1, and the cylinder body end of hydraulic cylinder 3 links to each other with bearing pin 2, and the tailpiece of the piston rod of hydraulic cylinder 3 links to each other with push arm 5 one ends, and push arm 5 other ends are connected with main shaft 7 by spline, and main shaft 7 is connected by spline between the pawl 4 with rake.Push arm 5, main shaft 7 all are installed in the drive seat 6, and drive seat 6 is by being bolted on the shovel board 1.
During the work of the utility model rake claw drive unit, when the piston rod of hydraulic cylinder 3 stretches out, be turned back to shovel board 1 centre position by push arm 5 and main shaft 7 drive rake pawls 4, when the piston rod of hydraulic cylinder 3 is withdrawn, drive rake pawls 4 by push arm 5 and main shaft 7 and be turned back to apart from shovel board 1 middle highest distance position.
More than rake claw drive unit structure provided by the utility model is described in detail, used specific case principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
