Abstract
The invention discloses a weldless light-duty crusher frame. The weldless light-duty crusher frame comprises side wall plates (1), a front wall (4) and a crossbeam (7). The front wall (4) are installed and fixed between the two side wall plates (1) by hinge pins (2) and bolts (3). The front wall (4) is located in front of the side wall plates (1). The crossbeam (7) is installed and fixed between the two side wall plates (1) by hinge pins (5) and bolts (6) and is located behind the side wall plates (1). Through use of pinhole and connection bolt fastening, frame welding is completely avoided and the problem of stress concentration caused by frame welding or casting is solved.
Description
Technical field
The jaw crusher that the present invention relates to a kind of broken stone, metallic ore, urban architecture rubbish, coal cinder etc., is specifically related to a kind of non-welding light-duty crusher frame.
Background technology
As everyone knows, jaw crusher comprises framework portion, moving jaw portion and driving section; Moving jaw portion forms by moving gnathosoma, tooth plate and main shaft and bearing; Driving section is made up of motor, electrical machine belt pulley, moving jaw main shaft, primary shaft belt pulley and flywheel; Framework portion is made up of two framed side wallboards, a casting front wall, a casting beam; Move jaw portion and be fixed in frame, after material enters, carry out attrition crushing by moving, fixed two tooth plates.Framework portion is bearing the effect of repeated stock power, once meet stress concentration point, what first damage will be this point, be easy to like this cause the fracture of whole frame.The difficult ease of casting frame and welding stand has stress concentration point, although have stress treatment measures before installation, is difficult to thoroughly eliminate; A lot of producers to concentrate and bring frame fracture in order to eliminate stress, and normally one strengthen framed side wallboard thickness, and two increase side wall reinforcement, and three increase front wall and crossbeam thickness of slab, have so virtually increased machine weight, have increased entreprise cost.
Summary of the invention
The object of the invention is: a kind of non-welding light-duty crusher frame is provided, adopts pin-and-hole attachment bolt fastening, nowhere whole frame welds, solve frame because of welding or cast the problem of stress concentration of bringing.
Technical solution of the present invention is: this frame comprises framed side wallboard, front wall and crossbeam, front wall is fixed between the wallboard of both sides through bearing pin and bolt, front wall is positioned at the front orientation of framed side wallboard, and crossbeam is fixed between the wallboard of both sides through bearing pin and bolt, and crossbeam is positioned at framed side wallboard back side.
Framed side wallboard thickness of the present invention only have former welding stand 80% and there is no a welding stress, frame weight only have former casting weight 70% and there is no a casting stress, pin-connected panel assembling, it is time saving and energy saving to assemble, be adapted to especially the underground work of mining, take transportation apart and solve the super wide problem of superelevation.
Accompanying drawing explanation
Fig. 1 is assembling schematic diagram of the present invention.
In figure: 1 framed side wallboard, 2 bearing pins, 3 bolts, 4 front walls, 5 bearing pins, 6 bolts, 7 crossbeams.
The specific embodiment
As shown in Figure 1, this frame comprises framed side wallboard 1, front wall 4 and crossbeam 7, and front wall 4 is fixed between both sides wallboard 1 through bearing pin 2 and bolt 3, and front wall 4 is positioned at the front orientation of framed side wallboard 1, crossbeam 7 is fixed between both sides wallboard 1 through bearing pin 5 and bolt 6, and crossbeam 7 is positioned at framed side wallboard 1 back side.
Claims (1)
