Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present utility model.
In figure, shovel bar 1, bar head handle 2, left side 21, right side 22, through hole 23, jaw 3, strengthens handle 4, flange 41, step 42, lining 5, end face 51, junction plate 6.
Detailed description of the invention
The utility model is described further as follows below in conjunction with drawings and Examples:
As shown in Figure 2, electric shovel rod, comprises shovel bar 1 and bar head handle 2, the axis of described shovel bar 1 and the dead in line of bar head handle 2, described bar head handle 2 comprises left side 21 and right side 22, and bar head handle 2 is provided with bar head handle 2 axis for center line and the through hole 23 of bar head handle 2; Comprise and strengthen handle 4, described reinforcement handle 4 is arranged between shovel bar 1 and bar head handle 2, and with the left side 21 of bar head handle 2 with shovel bar 1 and be fixedly connected with; Described reinforcement handle 4 is provided with the one week flange 41 be plugged in bar head handle 2 through hole 23, and described flange 41 extends to right side 22 by the left side 21 of bar head handle 2.
The left side 21 of described bar head handle 2 is the end face of bar head handle 2 near shovel bar 1 one end, and the end face of bar head handle 2 other end is right side 22.The left side 21 of bar head handle 2 with strengthen handle 4 and be welded to connect, bar head handle 2 closes with jaw 3 handle in the one end at place, right side 22.Described reinforcement handle 4 is arranged between shovel bar 1 and bar head handle 2, and be fixedly connected with shovel bar 1, namely strengthen handle 4 one end and can dock fixing with shovel bar 1, as strengthened handle 4 and shoveling bar 1 and dock and weld, or strengthen handle 4 and shovel bar 1 are equipped with flange, removably connected by flange; Strengthen handle 4 also to dock with shovel bar 1.But comparatively speaking, reinforcement handle 4 and shovel bar 1 dock to be connected and easily occur that stress is concentrated, and are docked by flange, add operation, are unfavorable for producing, comprehensive, refer to strengthen handle 4 and shovel bar 1 butt welding when reinforcement handle 4 is fixedly connected with shovel bar 1.Shovel bar 1 transmits the active force come and is just delivered to reinforcement handle 4, due to strengthen handle 4 be fixedly connected with the left side 21 of bar head handle 2, and reinforcement handle 4 be provided be plugged on bar head handle 2 through hole 23 in one week flange 41, therefore, be delivered to the active force strengthening handle 4, just shared by bar head handle 2 and flange 41.Described flange 41 extends to right side 22 by the left side 21 of bar head handle 2, stressed on whole length direction of bar head handle 2 is in evenly, does not occur stressed weak link.So, strengthen the partial action power that handle 4 just shares the transmission of shovel bar 1, the active force making shovel bar 1 be directly delivered to bar head handle 2 reduces, and improve the application life of bar head handle 2, avoid frequently changing bar head handle 2, the replacing time limit of bar head handle 2 was increased to 3-5 by 1 year.
Preferably, as shown in Figure 2, described flange 41 is fixedly connected with by junction plate 6 with bar head handle 2, and described junction plate 6 is concordant with the right side 22 of bar head handle 2.
Because flange 41 stretches in the through hole 23 of bar head handle 2, flange 41 is equivalent to a semi girder, flexible, and therefore, described flange 41 is fixedly connected with by junction plate 6 with bar head handle 2, and described junction plate 6 is concordant with the right side 22 of bar head handle 2.Junction plate 6 and bar head handle 2, flange 41 are suitable.Junction plate 6 can with the cast molding of bar head handle 2 one, also can junction plate 6 outer peripheral face and bar head handle 2 be welded to connect, inner peripheral surface and flange 41 are welded to connect.Flange 41 just becomes simply supported beam by a semi girder, and intensity is strengthened.Due to bar head handle 2 at the one end at place, right side 22 and jaw 3 closing, junction plate 6 is concordant with the right side 22 of bar head handle 2, is equivalent to the contact area increasing bar head handle 2 and jaw 3.
Preferably, described junction plate 6 and the cast molding of bar head handle 6 one.
From above-mentioned embodiment: junction plate 6 and bar head handle 6 can one cast moldings, also can be welded to connect as shown in Figure 2.But junction plate 6 reduces the production process of electric shovel rod with the cast molding of bar head handle 6 one.Therefore, as preferably, described junction plate 6 and the cast molding of bar head handle 6 one.
Preferably, as shown in Figure 2, described shovel bar 1 is the rod member of hollow, and described reinforcement handle 4 is hollow member; Also comprise lining 5, it is inner that shovel bar 1 is stretched in described lining 5 one end, and the other end stretches into be strengthened handle 4 inside and is fixedly connected with reinforcement handle 4.
Shovel bar 1 is the rod member of hollow, saves material, and lighter than solid rod member, is convenient to casting.Lining 5 plays the effect connecting shovel bar 1 and strengthen handle 4, when shovel bar 1 docks with reinforcement handle 4, usually adopts and is welded to connect.Lining 5 plays the effect increasing weld strength.Meanwhile, lining 5 plays guide effect, because lining 5 is fixedly connected with reinforcement handle 4, when lining 5 stretches into shovel bar 1 inside, strengthens handle 4 just relative with shovel bar 1, direct welding.
Preferably, as shown in Figure 2, described reinforcement handle 4 is provided with the step 42 of dummy section projection wherein, and described lining 5 is positioned at the end face 51 strengthening handle 4 inside and leans the step 42 strengthening handle 4.
Conveniently strengthen being welded to connect of handle 4 and lining 5, strengthen the step 42 that handle 4 is provided with dummy section projection wherein, the welding directly between lining 5 end face 51 relative with step 42 and step 42.And lean step 42 by strengthening the end face 51 of handle 4, make lining 5 can by a part of force transmission to strengthening handle 4.
Preferably, described reinforcement handle 4 is forge piece.
Strengthening handle 4 can be cast member, can be also forge piece, but due to self technological reason, it is good that cast member intensity is not so good as forge piece, and therefore, as preferably, described reinforcement handle 4 is forge piece.
