Description

Derrick crane intersection Anchored Bar

Technical field

The utility model relates to derrick crane attachment device field, especially derrick crane intersection Anchored Bar.

Background technology

The attachment device of derrick crane typically requires several Anchored Bars to be arranged on and adheres to frame and be positioned at same level, and distance, Angle is suitable, when due to the restriction of the many factors such as construction site, support position or attachment position, Anchored Bar must be adopted sometimes By the scheme of arranged crosswise, however, to ensure that the stress of Anchored Bar, Anchored Bar needs to be generally aligned in the same plane, and how to ensure to be subject to Carry out arranged crosswise particularly important in the case that power is good.

Utility model content

Technical problem to be solved in the utility model is: provide one to intersect in same level and stress is good, structure is simple Single derrick crane intersection Anchored Bar.

Be the technical scheme is that derrick crane intersection Anchored Bar by solving above-mentioned technical problem the utility model, including hand over Pitching the first Anchored Bar being connected on attachment device and the second Anchored Bar, also including jointing, jointing is by base and connection Plate forms, and connecting plate is vertically fixed on the two ends of base parallel with the long limit of base；First Anchored Bar is two-stage structure and passes through Jointing is connected, and the termination being connected in axial direction is provided with notch, and connecting plate inserts notch and is welded to connect with termination； Second Anchored Bar passes through from jointing.

Further: described connecting plate is four, the two ends of base are each parallel fixes two；The quantity of the notch of termination and position Put and match with connecting plate.

Further: also include locking bar, connecting plate upper end is provided with lockhole, and locking bar is connected with connecting plate by bearing pin, locking bar Form " mouth " shape structure with jointing.

Further: described locking bar is the frame structure being mutually perpendicular to be welded by four pieces of steel bars.

The beneficial effects of the utility model are: be welded to connect with jointing after the first Anchored Bar is divided into two sections, then allow Two Anchored Bars pass through from jointing, meet the requirement that two Anchored Bars intersect in same level；The utility model is tied Structure is simple, easy to assembly, be connected firmly, the stress of Anchored Bar is good.

Detailed description of the invention

For the ease of understanding the utility model, below in conjunction with the accompanying drawings the utility model is further detailed.

As it is shown in figure 1, the utility model includes the first Anchored Bar 1 on attachment device for the interconnection and the second Anchored Bar 2； As in figure 2 it is shown, in order to allow the first Anchored Bar 1 and the second Anchored Bar 2 can be positioned at same level while intersecting, Adding jointing 3, jointing 3 includes base 31 and connecting plate 32；Connecting plate 32 is hammered into shape and is directly welded on the two of base 31 End, connecting plate 32 position at two ends is corresponding, and parallel with the long limit of base 31；As shown in Figure 4, Figure 5, the first attachment Bar 1 is two-stage structure, and the termination of every section is in axial direction provided with notch 11, and connecting plate 32 is welded to connect after inserting notch 11； Base 31 and connecting plate 32 form the structure of U-shaped like, and the second Anchored Bar 2 passes through from jointing 3.

As shown in Figure 2 and Figure 3, connecting plate 32 four altogether in the utility model, the two ends of base 31 are each parallel fixes two, Notch 11 quantity of the first Anchored Bar 1 termination and position match with connecting plate 31, connecting plate 32 two notches of correspondence 11.The quantity of connecting plate 32 is selected also dependent on actual conditions, minimum for each one of one end, it is ensured that the end with the first Anchored Bar 1 Head welds.In the present embodiment, the intensity in order to ensure junction has selected four.

In order to ensure that the second Anchored Bar 2 will not skid off in jointing 3, as shown in Figure 2 and Figure 3, on jointing 3 Increasing locking bar 4, the upper end of connecting plate 32 is provided with lockhole, and locking bar 4 is provided with the through hole corresponding with lockhole, by locking bar 4 and company Fishplate bar 32 is connected by bearing pin 41, and locking bar 4 and jointing 3 form " mouth " shape structure, play position-limiting action, by second Anchored Bar 2 surrounds.

As it is shown on figure 3, locking bar 4 is positioned between connecting plate 32, owing to the utility model being selected four pieces of connecting plates 32, locking bar 4 Two ends are respectively connected with two pieces of connecting plates 32, in order to ensure the fastness of jointing 3, best between locking bar 4 and connecting plate 32 Very close to each other, and also to increase the intensity of locking bar 4, locking bar 4 is the square frame knot being mutually perpendicular to be welded by four pieces of steel bars Structure.
