Description
Technical field
The utility model relates to underframe hound structure, and specifically a kind of tower crane interpolation type underframe hound structure, belongs to tower crane technical field.
Background technology
Present stage, domestic tower machine industry homogeneity competition is serious, and especially in middle-size and small-size tower machine field, each producer product design, price are on a par, and surface structure, dismounting transportation mode are very nearly the same.So for domestic Ta Ji enterprise, want to win the market, obtain client's favor, also need convenient transportation and the economic and practical of improving product, at utmost meet client's high performance-price ratio demand.So continue to optimize product structure, reduce manufacturing cost, improving product performance for making product core competitiveness, maintaining enterprise brand advantage is significant.
In existing product design, the underframe hound two ends of tower crane are all with ears plate 21 (as Fig. 1 and Fig. 2), and ears plate 21 spacing are less, when assembling, coordinate with the monaural plate 8 on underframe joint 1, connect by bearing pin.Therefore, on underframe joint 1, must weld four unsettled monaural plates 8 and be connected with hound 3, certainly will increase the bulk of underframe joint.Because other standard knot is regular cubic space structure, underframe saves four jiaos and hangs monaural plate only, inconsistent with standard knot bulk, so very inconvenience when entrucking transport.In addition, because monaural plate and underframe joint weld seam are that monaural plate thickness face docks with underframe joint main chord, weldquality is had relatively high expectations, and is not easy to ensure.
Summary of the invention
For the deficiency existing in existing hound technology, the utility model provides a kind of tower crane interpolation type underframe hound structure, for making underframe joint oad and standard knot unified, tactical rule compactness, strengthen the convenience of underframe joint transport, meanwhile, optimize connecting portion structure, improve connection location force-bearing situation, effectively reduce weldquality requirement.
For solving the problems of the technologies described above, a kind of tower crane interpolation type of the utility model underframe hound structure, comprises base section, underframe joint and hound, and base section bottom is vertically fixedly connected on rood beam; Underframe joint bottom is fixedly connected on the end face of base section; Hound favours rood beam setting, its bottom is fixedly connected with rood beam, its top is fixedly connected with underframe joint, the top of described hound is provided with " U " type structure ears plate being fixedly connected with it, and the home record size of described ears plate " U " type structure matches with the width dimensions of main chord; Hound top is enclosed within by ears board on the main chord of underframe joint, and the top of ears plate is fixedly connected with the main chord of underframe joint by attaching parts.
As preferably, attaching parts is bearing pin.
Further, bearing pin one end is provided with positioning step, and the other end is provided with screw thread and the anti-return nut with screw thread fit.
Further, the inside face of " U " type structure ears plate bottom on hound top is ramp structure, and its bevel angle is identical with the angle between hound and the main chord of underframe joint.
Compared with prior art, the utlity model has following advantage:
(1) underframe joint integral structure size reduction, convenient transportation strengthens.The utility model has removed the monaural plate on underframe joint main chord, makes underframe joint oad and standard knot unified, and tactical rule compactness has significantly been reduced the overall dimensions that underframe saves, relatively traditional underframe joint, and convenient transport is strong.
(2) improve connecting portion force-bearing situation, effectively reduced weldquality requirement.The weld seam stressing conditions of tradition connection mode underframe joint main chord and monaural plate is severe, must strictly control weldquality, avoids weld seam to produce low cycle fatigue cracking.Connecting portion of the present utility model has removed monaural plate, the ears distance between plates of hound is increased, extend ears plate and embrace underframe joint main chord, this kind of connection mode force-bearing situation obtained improving significantly, effectively reduced near the weldquality requirement of joint, convenient welding is quick.
(3) the utility model is on the basis of existing structure, hound and connection mode thereof to be improved, and overall structure variation is little, does not increase any manufacturing process burden, simple in structure, be easy to manufacture, and low cost of manufacture.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figures 3 to 5, a kind of tower crane interpolation type of the utility model underframe hound structure, is mainly made up of base section 6, underframe joint 1 and hound 3, and base section 6 bottoms are vertically fixedly connected on rood beam 7; Underframe saves 1 bottom and is fixedly connected on the end face of base section 6; Hound 3 favours rood beam 7 and arranges, its bottom is fixedly connected with rood beam 7, its top is fixedly connected with underframe joint 1, the top of described hound 3 is provided with " U " type structure ears plate 2 being fixedly connected with it, the home record size of described " U " type structure ears plate 2 matches with the width dimensions of main chord 4, prevent the phenomenon appearance that " U " type structure ears plate 2 and main chord 4 occur double swerve, slide up and down, make the two in conjunction with more tight, firm; Hound 3 tops are fastened in by ears plate 2 on the main chord 4 of underframe joint 1, and the top of ears plate 2 is fixedly connected with the main chord 4 of underframe joint 1 by attaching parts 5.
The preferred version that changes as the utility model to technique scheme, for fastening " U " type structure ears plate 2, is better fixed on main chord 4 hound 3, and described attaching parts 5 is bearing pin.
Further improvement as the utility model to technique scheme, described bearing pin one end is provided with positioning step, the other end is provided with screw thread and the anti-return nut with screw thread fit, the use of anti-return nut, prevent that on the one hand nut is because using and occur loosening phenomenon for a long time, the spacing that can further further between ears plate 2 by modulation anti-return nut on the other hand, further reduce ears plate 2 and main chord 4 gaps, increasing friction force, thereby make the support underframe joint 1 that hound 3 is more firm, further increase the safety and reliability of equipment in work progress.
Further improvement as the utility model to technique scheme, the inside face of " U " type structure ears plate 2 bottoms on described hound 3 tops is ramp structure, its bevel angle is identical with the angle between hound 3 and the main chord 4 of underframe joint 1.Can increase the area of contact of hound 3 and main chord 4, increasing friction force, makes to connect more firm.
The utility model has removed four unsettled monaural plates on traditional underframe joint 1, ears distance between plates on hound 3 is strengthened, and increase ears plate length, ears plate after improvement is " U " type structure, make " U " type structure ears plate 2 on hound 3 directly embrace the main chord 4 of underframe joint 1, then connect by attaching parts 5.The utility model has reduced the bulk of underframe joint 1, has significantly promoted the convenient transportation of underframe joint 1, and has effectively improved the stressing conditions of connecting portion.
