Description

Technical Field

[0001] This utility model relates to the field of roadbed box technology, specifically a roadbed box for a crawler crane. Background Technology

[0002] Tracked cranes are heavy and generate significant concentrated pressure during operation. The roadbed box distributes this pressure evenly across the ground, preventing subsidence, deformation, or even damage caused by excessive localized pressure, thus ensuring the stability and safety of the crane during operation.

[0003] Currently, existing tracked crane roadbed boxes typically employ an integrated structure or use welding to fix the upper and lower metal plates together. After long-term use, if the metal plates wear or become damaged, it is difficult to disassemble and replace the upper and lower metal plates individually, resulting in high maintenance costs and low efficiency. Furthermore, in practical engineering applications, multiple roadbed boxes are often needed to support the tracked crane. This can lead to movement between the roadbed boxes during crane operation, affecting the crane's stability and operational safety.

[0004] Based on the above reasons, this utility model proposes a roadbed box for a crawler crane, which enables convenient maintenance and stable use of the roadbed box. Utility Model Content

[0005] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a roadbed box for a crawler crane, which has the advantages of convenient maintenance and stable use.

[0006] The technical solution adopted by this utility model to achieve the above objectives is: a roadbed box for a crawler crane, comprising a rectangular frame, a support frame fixedly connected inside the rectangular frame and a connecting plate fixedly connected to each of the four outer walls, a transverse groove provided on the connecting plate, a positioning rod inserted into the transverse groove, metal plates provided on the upper and lower side walls of the rectangular frame, and mounting components provided on the side walls of the metal plates.

[0007] In the above technical solution, the mounting assembly includes side plates, and side plates are fixedly connected to the four side walls of the metal plate. Threaded holes are opened on the four side walls of the rectangular frame, and fixing bolts that are threadedly connected to the threaded holes are movably connected to the side plates.

[0008] In the above technical solution, the thickness of the side plate is set to be equal to half the thickness of the rectangular frame and the sum of the thickness of the metal plate.

[0009] In the above technical solution, the connecting plates on the left and front sides are set to the same height, the connecting plates on the right and rear sides are set to the same height, the bottom surface of the connecting plate on the left side and the top surface of the connecting plate on the right side are set to the same height, and the bottom surface of the connecting plate on the front side and the top surface of the connecting plate on the rear side are set to the same height.

[0010] In the above technical solution, the bottom end of the positioning rod is conical, and the top end of the positioning rod is fixedly connected to a top plate.

[0011] In the above technical solution, several metal strips are fixedly connected to the side wall of the metal plate away from the rectangular frame.

[0012] In the above technical solution, the support frame includes a horizontal tube, and several horizontal tubes are evenly distributed and fixedly connected to a rectangular frame. Several connecting tubes are evenly distributed and fixedly connected to both sides of the horizontal tube, and the connecting tubes on both sides are fixedly connected to the rectangular frame.

[0013] The beneficial effects of this utility model are:

[0014] 1. When splicing several roadbed boxes, the cross grooves are made through the staggered arrangement of adjacent connecting plates. Then, positioning rods are inserted into the cross grooves and the top plate is hammered to insert the positioning rods into the ground, thereby connecting the connecting plates and completing the splicing and fixing of the roadbed boxes, reducing the occurrence of movement, and thus achieving stable use of the roadbed boxes.

[0015] 2. When it is necessary to replace or maintain the metal plate, the fixing bolts can be removed to release the fixation between the side plate and the rectangular frame, making it easy to remove the metal plate. The new metal plate can then be placed on the rectangular frame, and the fixing bolts can be tightened to fix the side plate, thus completing the replacement of the metal plate. It is convenient to use. Attached Figure Description
