Referring to fig. 2, the split type two-bucket rotary drilling bit connecting square box assembly comprises:
the connecting square box 100 is provided with a first connecting plate 200 at the bottom end of the connecting square box 100;
the two hinge middle sleeves 300 are fixedly arranged on the lower end face of the first connecting plate 200 in parallel;
the second connecting plate 400 is fixedly arranged on the lower end surfaces of the two hinge middle sleeves 300, and the first connecting plate 200 and the second connecting plate 400 enclose the two hinge middle sleeves 300 between the two hinge middle sleeves;
the first connecting plate 200 and the second connecting plate 400 are connected to each other through the plurality of connecting rib plates 500, and the connecting rib plates 500 are fixedly connected with the connecting square box 100.
First connecting plate 200 welds the bottom at connecting square chest 100, and cover 300 welds between first connecting plate 200 and second connecting plate 400 in two hinges, and connecting rib plate 500 and connecting square chest 100 rigid coupling simultaneously to great improvement cover 300 and connecting square chest 100's joint strength in the hinge, reduced in the connection between cover 300 and the connecting square chest 100 welding seam fracture lead to the risk that drops. The middle sleeve 300 is connected with the hinge edge sleeve on the cylinder body 600, so that the risk that the cylinder body 600 falls into the pile hole is reduced.
According to the utility model discloses a some embodiments, connecting rib plate 500 is four, and the setting of four two bisymmetries of connecting rib plate 500 is equipped with the draw-in groove on connecting rib plate 500 in the left and right sides of connecting square chest 100, first connecting plate 200 and second connecting plate 400 set firmly the draw-in groove in, connecting rib plate 500's upper portion and connecting square chest 100 rigid couplings.
The first connecting plate 200 and the second connecting plate 400 are fixedly arranged in the clamping groove, so that the welding position is located in the clamping groove area, the exposure of the welding position is reduced, the risk of abrasion and cracking of the welding position in the use process is reduced, and the possibility of falling off of the second connecting plate 400 can be reduced.
In the conventional connection square box shown in fig. 1, the reinforcing frame 120 only needs to be welded to the box body 110, and in order to reduce the welding difficulty, the upper end surface of the reinforcing frame 120 is usually lower than the upper end surface of the box body 110, and the pressure of the drill rod of the rotary drilling machine is borne by the upper end surface of the box body 110 and the pin shaft of the box body 110 matching with the drill rod. In the using process, the part of the upper part of the box body 110 protruding out of the reinforcing frame 120 is often easily deformed by pressure, and the pin shaft bears the pressure alone, so that the pin shaft is easily broken, the barrel body falls off, and the safety is low and the cost is high.
According to the utility model discloses a some embodiments, connect square chest 100 and include box 110 and reinforcement frame 120, box 110 inside cavity and top opening are for the matching of rotary drilling machine drilling rod to insert, and week side is equipped with box through-hole 111, and the up end of box 110 is the plane, and reinforcement frame 120 cover is established at box 110 week side in order to be used for strengthening box 110, and reinforcement frame 120 up end is the plane, and with box 110 up end parallel and level.
By arranging the upper end surfaces of the reinforcing frame 120 and the box body 110 to be flat and level, when the drill rod of the rotary drilling machine is pressed down, the reinforcing frame 120 and the box body 110 bear pressure together, so that the pressure bearing area is increased, and excessive abrasion and deformation of the box body 110 are avoided.
As shown in fig. 3, the lower portion of the drill rod of the rotary drilling machine is provided with a connector for connecting with the casing 110, the connector includes a connector body 710 and a connector cap 720, and the connector body 710 is provided with a connecting pin hole 730.
The interior of the box body 110 is hollow and has an upper opening for the drill rod of the rotary drilling machine to be inserted in a matching manner, specifically, the interior space of the box body 110 is matched with the connector body 710 at the lower part of the drill rod of the rotary drilling machine, the box body 110 is provided with box body through holes 111 on the periphery side to be matched with the connecting pin holes 730, so that the box body 110 and the drill rod of the rotary drilling machine are connected by using the pin shaft not shown to be inserted, and the upper end surface of the box.
The reinforcing frame 120 is disposed around the box body 110 for reinforcing the box body 110, and an upper end surface of the reinforcing frame 120 is a plane and flush with an upper end surface of the box body 110. It is contemplated that after the case body 110 and the reinforcing frame 120 are assembled, the upper surface of the case body 110 and the upper surface of the reinforcing frame 120 are at the same level and can jointly bear the pressure of the connector cap 720, i.e., the pressed area is increased, thereby preventing the case body 110 from being excessively deformed.
In some embodiments of the present invention, the case through hole 111 includes a first pin hole 1111 that penetrates through a set of opposite surfaces of the case 110, and the first pin hole 1111 is vertically arranged to be provided in plurality. Through vertical arrangement be provided with a plurality of first pinhole 1111, different model connectors, its pinhole height is different, selects suitable first pinhole 1111, has improved the suitability.
The case through hole 111 further includes a second pin hole 1112 penetrating from the other set of opposing surfaces of the case 110. For some connectors with pin holes on multiple surfaces, the first pin hole 1111 and the second pin hole 1112 can be matched with the connectors, so that the application range is expanded. It is contemplated that in other embodiments, the second pin holes 1112 may be arranged in a plurality of vertical rows according to the specification of a common connector, or may be designed in other forms.
The case through hole 111 is a kidney-shaped hole. Through setting up to waist type hole, effectively reduce to produce in the use gyration moment of torsion shearing force and cut off connecting pin to increase round pin axle life, thereby guarantee quality and reduce cost.
Of course, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention, and such equivalent modifications or substitutions are included in the scope defined by the claims of the present application.
