Abstract

The invention relates to a roadbed box for a large crawler crane in the technical field of industrial and mechanical construction. The roadbed box comprises a frame, an inclined vertical plate, a cover plate and a bottom plate. The inclined vertical plate is located in the frame, and the cover plate and the bottom plate are respectively located on the upper and lower parts of the frame and connected with the frame. The roadbed box provided by the invention is novel and reasonable in arrangement mode, and good in stress performance. Interval flanges are arranged on a long vertical plate, grooves are formed in the bottom plate, and the flanges are inserted into the grooves of the bottom plate. According to the connection method, deformation of the roadbed box can be effectively reduced. Four lugs are arranged inside notches of the frame for facilitating hoisting and conveyance.

Description

The subgrade case that is used for the large caterpillar car

Technical field

What the present invention relates to is nuclear industry mechanized construction technical field, specifically a kind of subgrade case for 3200 tons of pedrail cranes of the biggest lifting capacity.

Background technology

China's generation Ⅲ nuclear power autonomy-oriented nuclear power station project adopts in the world state-of-the-art presurized water reactor technology AP1000, adopt the modularization building technology, in construction and the installation a large amount of heavy mail lifting work are arranged, need to adopt large-scale tracklaying crane (3200 tons of the biggest lifting capacities), during this type of large-scale crane operation, if it is very high that crawler belt directly contacts the requirement of ground with ground, in order to reduce the requirement to bearing capacity of foundation soil, need to use subgrade case to carry out load distribution.

Find Chinese patent literature CN20181796U, open day 2011-04-20 through the retrieval to prior art, put down in writing a kind of subgrade case of large-scale crawler engineering vehicle, comprise the closed cavity casing, the frame of casing adopts shaped steel to make, and upper surface and soffit adopt steel plate to consist of; Described casing is surrounded in the formation cavity and is provided with the reinforcing rib of being made by shaped steel by frame, upper surface, soffit.Described reinforcing rib two ends are fixedly connected with frame.Upper and lower surface is fixedly connected with soffit with the upper surface of casing respectively.But this subgrade case adopts substantially solid structure, and own wt is heavy, in use carrying inconvenience, and also steel use many when making.

Summary of the invention

The present invention is directed to the prior art above shortcomings, propose a kind of subgrade case for the large caterpillar car, can solve traditional subgrade case Heavy Weight, carrying inconvenience, the many problems of consumption steel when making.

The present invention is achieved through the following technical solutions, and the present invention includes: framework, oblique riser, cover plate and base plate, and wherein: oblique riser is arranged in framework, and cover plate lays respectively at the upper-lower position of framework with base plate and links to each other with framework.

Described framework comprises: elongated riser and horizontal riser, wherein: elongated riser and the laterally orthogonal interconnection of riser.

Establish spaced flange on the described elongated riser, this flange specifically is positioned at the lower limb of elongated riser.

1/3 to 2/3 place of described oblique riser air line distance between the elongated riser in both sides.

Described base plate is provided with the groove corresponding with the flange of elongated riser.

Be fixed with four hangers on the described cover plate, described four hangers arrange in symmetrical each two mode in front and back.

Described hanger is positioned at the recess that is arranged on the cover plate, and the outer of the outer of hanger and horizontal riser is positioned at same vertical plane.

Beneficial effect

Compared with prior art, positioning means of the present invention are new reasonable, and stress performance is good; Elongated riser is provided with spacer lug, has groove on the base plate, and flange inserts in the groove of base plate, and this method of attachment can effectively reduce the distortion of subgrade case, is provided with four hangers in the recess of cover plate, convenient lifting transportation.

The specific embodiment

The below elaborates to embodiments of the invention, and the present embodiment is implemented under take technical solution of the present invention as prerequisite, provided detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.

Embodiment 1

As shown in Figure 1, 2, the present embodiment comprises, framework 1, oblique riser 2, cover plate 3 and base plate 4, and wherein: oblique riser 2 is arranged in framework, and it is coupled that cover plate 3 is positioned at the top of framework, and it is coupled that base plate 4 is positioned at the below of framework.

Described framework 1 comprises: elongated riser 5 and horizontal riser 6, wherein: elongated riser 5 and laterally riser 6 orthogonal interconnections.

As shown in Figure 3, described elongated riser 5 is established spaced flange 7.

As shown in Figure 4, described base plate 4 is provided with the groove corresponding with the flange 7 of elongated riser.

Described flange 7 is positioned at the lower limb of elongated riser, and is connected with the groove of base plate.After the connection, the weld seam in the groove is filled up welding, at last that base plate 4 surface finish are smooth.

As shown in Figure 1, described oblique riser 2 is arranged in framework 1, specifically 1/3 to 2/3 place of air line distance between the elongated riser in both sides.

As shown in Figure 1, be fixed with four hangers 8 on the described framework 1, described four hangers 8 arrange in symmetrical each two mode in front and back.

Described hanger 8 is positioned at the recess 9 that is arranged at framework 1, and the outer of the outer of hanger 8 and horizontal riser 6 is positioned at same vertical plane.

Described elongated riser 5, horizontal riser 6, oblique riser 2, cover plate 3 and base plate 4 all adopt Q345B steel for building.

Scantling of the present invention, material are selected, technological design can be determined for concrete application, can adjust subgrade case overall size, steel plate thickness and cover plate fluting welding position and size according to crane load.

For example, the load that bears on large caterpillar car lifting capacity 3200 ton hours, subgrade case and face that the crane crawler belt contacts is about 2.4Mpa, designed size is: elongated riser (thick 25mm), horizontal riser (thick 20mm), oblique riser (thick 20mm), cover plate (thick 25mm), base plate (thick 25mm).Heavily approximately 13 tons of each subgrade cases, planar dimension (outline) is 3m * 6m, height 0.35m.
