Abstract
The utility model relates to a heavy-duty project frontal hoist frame with integrated amplitude variation oil cylinder bearing seats, and solves the problem that the concentricity of the left and the right bearing seats of the prior heavy-duty project front hoist frame is not easy to be ensured. The heavy-duty project frontal hoist frame is characterized in that through holes are opened at the corresponding positions on the both sides of the frame, integrated amplitude variation oil cylinder bearing seats are inserted in the through holes, the middle parts of the integrated amplitude variation oil cylinder bearing seats adopt multi-edge columns, fixed grooves are formed at the radial positions of the both ends, bearing seat holes are formed at the axial positions of the both ends, and the integrated amplitude variation oil cylinder bearing seats are fixed with the through holes by welding. The heavy-duty project frontal hoist frame can ensure the concentricity of the left and the right bearing seats, the effect of welding deformation is reduced, and the requirements on assembly die assemblies are reduced.
Description
Technical field
The utility model relates to a kind of heavy engineering car vehicle body, specifically has the heavy engineering front crane carriage of integral type amplitude oil cylinder supporting base.
Background technology
Left and right sides amplitude oil cylinder supporting base is installed on the heavy engineering car vehicle body, the amplitude oil cylinder supporting base is the mechanical mechanism of support left and right sides amplitude oil cylinder, the amplitude oil cylinder supporting base is welded on the car body, bearing the Container Weight of deadweight and institute's load of telescopic boom by amplitude oil cylinder, at present, the amplitude oil cylinder supporting base that hang in homemade heavy engineering front generally adopts split-type structural, the supported at two edges seat will be distinguished welding separately in welding process, the right alignment in left and right sides supporting base hole is not easy to guarantee under the influence of welding deformation, must realize by high-precision assembly jig, the productive costs height, manufacture difficulty is big, and aspects such as butt welded seam quality and welding deformation have proposed higher requirement simultaneously.
Summary of the invention
The purpose of this utility model provides a kind of heavy engineering front crane carriage with integral type amplitude oil cylinder supporting base.
Concrete structural design scheme is as follows:
Have the heavy engineering front crane carriage of integral type amplitude oil cylinder supporting base, comprise vehicle frame, have through hole, in through hole, be fitted with integral type amplitude oil cylinder supporting base in the position of the corresponding installation amplitude oil cylinder in vehicle frame both sides; Integral type amplitude oil cylinder supporting base middle part is the polygon cylinder, and its two ends radial position is respectively equipped with hold down groove, the axial coaxial supporting base hole that is provided with of at both ends;
Fixing between the through hole on integral type amplitude oil cylinder supporting base and the vehicle frame by welding.
This uses later-model useful technique effect to be embodied in following aspect:
1, utilizes metalworking equipment directly to guarantee supporting base hole, left and right sides right alignment, reduce the influence of welding deformation;
2, reasonable structural design reduces the weldquality requirement, improves safety performance;
3, improve welding process, reduce requirement, effectively reduce welding difficulty and manufacturing cost assembly jig.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of integral type amplitude oil cylinder supporting base of the present utility model;
Fig. 3 is the birds-eye view of integral type amplitude oil cylinder supporting base of the present utility model.
Below in conjunction with accompanying drawing, the utility model is further described by embodiment:
Heavy engineering front crane carriage with integral type amplitude oil cylinder supporting base comprises vehicle frame 2, position in the corresponding installation amplitude oil cylinder in vehicle frame 2 both sides has the through hole (see figure 1), in through hole, be fitted with integral type amplitude oil cylinder supporting base 1, fixing between the through hole on integral type amplitude oil cylinder supporting base 1 and the vehicle frame 2 by welding; Integral type amplitude oil cylinder supporting base 1 middle part is a polygon cylinder (see figure 2), and its two ends radial position is respectively equipped with hold down groove 4, axial coaxial supporting base hole 3 (see figure 3)s that are provided with of at both ends; The right alignment in the supporting base hole 3 at two ends is directly guaranteed by equipment by the mode of carrying out machine up after welding again, avoided the influence of welding deformation in the split-type structural, fixing between integral type amplitude oil cylinder supporting base 1 and through hole by welding, this in addition penetration type structure can also be directly delivered to the load of bearing on the supporting base on the car body, reduces the weld strength requirement of supporting base place greatly.
