Abstract
The utility model discloses a kind of reciprocating coal feeder crank mechanism, comprise adapter shaft and disk, the cross section of described adapter shaft one end is made as polygon-shaped, and disk is provided with the mounting hole matching with adapter shaft one end, and after adapter shaft one end is installed to mounting hole, girth welding together.Compared with prior art, the utility model unit design is reasonable, adapter shaft and disk mounting structure are square, the equipment alternation moment of rotation producing that is in operation is all born by tetragonal four faces, there is good practicality, during running, square opening can not cause greatly sealing-off to be rotated because vibrating, and well guarantees that equipment normally moves.
Description
Technical field
The utility model relates to load transfer device technical field, particularly a kind of reciprocating coal feeder crank mechanism.
Background technology
At present, at the industries such as coal in China, metallurgical mine load transfer device used, particularly in coal mine equipment, applying maximum is K type reciprocating feeder.This reciprocating coal feeder adopts Design of Crank, and feed process is reciprocating, and vibration equipment is large, and structure stress is large.The crank at crank mechanism place is the place that is prone to problem, crank is comprised of adapter shaft and disk, the structure of disk and adapter shaft is that cylindrical pin location adds circumferential weld and fixes, and disk is that minimum clearance coordinates with adapter shaft, and dependence accurate to dimension guarantees.
Because the installation place of adapter shaft and disk is circular hole, and both are welding, during equipment operation, can produce very large alternation moment of rotation, adapter shaft can produce and swing under the impact of alternation couple, and straight-line motion can produce vibration, and the weld seam of the disc and shaft produces fracture by fatigue and sealing-off under the effect of long-term alternation moment of rotation, adapter shaft idle running, and then make production efficiency of equipment low, and when serious, can cause floor sliding, cause serious industrial accident.
Summary of the invention
The purpose of this utility model is the reciprocating coal feeder crank mechanism that a kind of safe and stable operation will be provided.
For achieving the above object, the utility model is implemented according to following technical scheme:
A reciprocating coal feeder crank mechanism, comprises adapter shaft and disk, and the cross section of described adapter shaft one end is made as polygon-shaped, and disk is provided with the mounting hole matching with adapter shaft one end, and after adapter shaft one end is installed to mounting hole, girth welding together.
As preferably, the cross section of described adapter shaft one end is made as quadrangle shape.
Compared with prior art, the utility model unit design is reasonable, adapter shaft and disk mounting structure are square, the equipment alternation moment of rotation producing that is in operation is all born by tetragonal four faces, there is good practicality, during running, square opening can not cause greatly sealing-off to be rotated because vibrating, and well guarantees that equipment normally moves.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is lateral plan of the present utility model;
Fig. 3 is the structural representation of disk of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described, in illustrative examples and the explanation of this utility model, is used for explaining the utility model, but not as to restriction of the present utility model.
A kind of reciprocating coal feeder crank mechanism as shown in Figure 1 and Figure 2, comprise adapter shaft 1 and disk 2, the cross section of adapter shaft 1 one end is made as polygon-shaped, and disk 2 is provided with the mounting hole 21 matching with adapter shaft 1 one end, and adapter shaft 1 one end is installed to the rear girth welding of mounting hole 21 together.
As shown in Figure 3, during use, quadrilateral hole is processed into in disk 2 and adapter shaft 1 installation place, both install rear girth welding together.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion of making according to the technical solution of the utility model, within all falling into protection domain of the present utility model.
