Abstract
The utility model belongs to the field of mining equipment, and in particular relates to a hoop for fastening shaft ends of an electric shovel push big shaft. The hoop for fastening the shaft ends of the electric shovel push big shaft comprises two annular shaft end hoops fixed at the shaft ends of two sides of the electric shovel push big shaft, and the two annular hoops are fixedly connected by two semicircular shaft end hoops through two fastening bolts. The hoop is characterized in that two reinforcing rib plates are fixed on hoop lugs on two sides of each of the two semicircular shaft end hoops, each of the two reinforcing rib plates is provided with a reinforcing threaded hole, and the two semicircular shaft end hoops are fixedly connected through two reinforcing bolts in threaded connection with the reinforcing threaded holes respectively. The hoop is convenient to assemble and disassemble, safe, reliable and long in service life; and by arranging the reinforcing bolts for fastening on the two sides of the shaft end hoops, the assembly strength of the push big shaft end hoop is greatly improved.
Description
Technical field
The utility model belongs to the winning equipment field, especially relates to a kind of clip that is used for fastening power shovel pushing macro-axis axle head.
Background technology
Power shovel is homemade surface mining equipment, and at present, known power shovel pushing macro-axis both sides axle head clip device is to adopt two semi-circular axle head clip butt joints to be fixed on the axle head of pushing macro-axis.Respectively there is a screwed hole at the two ends of two semi-circular axle head clips; Pass two screwed holes with two fastening bolts respectively two semi-circular axle head clips are fastened on the axle head that power shovel pushes macro-axis, form an annular axle head clip that is used for fastening power shovel pushing macro-axis axle head.In the power shovel running; Because there is axial fit-up gap in axial each parts of pushing macro-axis during left rotation and right rotation after assembling; And in the pushing transmission process, after the wearing and tearing, end play also will enlarge gradually between each parts; Therefore cause the clip of pushing macro-axis both sides shaft end, when power shovel rotation switching-over, bear and come from the pushing macro-axis each parts in axial inertial impaction.Under long-term inertial impaction; The clip screw produces fatigue break generation clip and comes off; More be prone to cause pushing to hold up the handle release failure thus, clip and hold up handle in moment comes off process, will directly bring huge potential safety hazard to personnel in the power shovel radius of gyration and vehicle.
Summary of the invention
The purpose of the utility model provides a kind of safe and reliable; Mounting or dismounting are convenient; The clip that is used for fastening power shovel pushing macro-axis axle head that life cycle is long, this installs in actual production process, not only saves maintenance cost; Reduce labor strength, and farthest reduced the incidence of industrial accident.
The purpose of the utility model realizes through following technical proposals:
A kind of clip that is used for fastening power shovel pushing macro-axis axle head of the utility model; Comprise two annular axle head clips that are fixed on the axle head of power shovel pushing macro-axis both sides; These two ring-shaped clips are fixedly connected through two fastening bolts by two semi-circular axle head clips; It is characterized in that respectively on the hoop ear of the both sides of described two semi-circular axle head clips, being fixed with two strengthens gussets; Strengthen respectively being provided with one on the gussets and reinforce screwed hole for described two, described two semi-circular axle head clips two through being threaded with described reinforcing screwed hole are respectively reinforced bolt and are connected.
The advantage of the utility model
A kind of clip that is used for fastening power shovel pushing macro-axis axle head of the utility model, mounting or dismounting are convenient, and safe and reliable, life cycle is long, and the both sides that are employed in the axle head clip are provided with the reinforcing bolton, and the assembling intensity of pushing macro-axis axle head clip is strengthened greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the left view of the utility model Fig. 1.
The specific embodiment
Further specify the specific embodiment of the utility model below in conjunction with accompanying drawing.
Like Fig. 1, shown in 2, a kind of clip that is used for fastening power shovel pushing macro-axis axle head comprises two annular axle head clips that are fixed on the power shovel pushing macro-axis 1 both sides axle head; These two ring-shaped clips are fixedly connected through two fastening bolts 7 by two semi-circular axle head clips 4; It is characterized in that respectively on the hoop ear 5 of the both sides of described two semi-circular axle head clips 4, being fixed with two strengthens gussets 2, the increase of strengthening gusset 2 has increased the intensity of two semi-circular axle head clips 4, strengthens respectively being provided with one on the gussets 2 and reinforces screwed hole 3 for described two; Described two semi-circular axle head clips 4 two through being threaded with described reinforcing screwed hole 3 respectively add fixing bolt 6 and are fixedly connected; Adopt this kind to add fixing bolt 6 and connect two semi-circular axle head clips 4, make connection more firm, become flexible in order to prevent the screw and the nut that add fixing bolt 6; Can also with the fastening back of the nut that adds fixing bolt 6 directly and lead screw weld together; The utlity model has simple in structurely, life cycle is long, easy accessibility; Cost is low, and can effectively guarantee characteristics such as device security running and reduction labor strength.
