[0028] The foregoing and other technical contents, features and effects of the present application will be further illustrated in the following detailed description of the embodiments in conjunction with the accompanying drawings. Figures 1-4 The structural contents mentioned in the following embodiments will be clearly presented with reference to the drawings.
[0029] The exemplary embodiments of the present application will be described below with reference to the accompanying drawings.
[0030] The present application relates to a kind of telescopic frame of heavy load flow car, the specific embodiments of the present application are further illustrated in the following in conjunction with drawings.
[0031] As shown in FIGS. 1-3, the telescopic frame of the present embodiment includes a main frame 1, a telescopic frame 2 and a telescopic assembly 3. The main frame 1 is made of high-strength metal material in a box structure, and a cavity capable of accommodating the telescopic frame 2 is formed inside. The main frame 1 includes a top plate 11 and a bottom plate 12, which are fixedly connected to form a frame structure by four support plates 13. The support plates 13 are symmetrically arranged at the center of the top plate 11, and a buffer pad 14 is arranged between adjacent support plates 13. The buffer pad 14 is made of elastic rubber material and is distributed radially at intervals with the center of the top plate 11 as the reference, which can effectively absorb the impact load during transportation.
[0032] Two telescopic frames 2 are symmetrically arranged inside the main frame 1, and the two telescopic frames 2 are connected by a telescopic connector 21 to realize linkage telescoping. The telescopic connector 21 adopts a cross-link mechanism, and its two ends are respectively hinged with the two telescopic frames 2. When the telescopic frames 2 move relatively, the length of the link mechanism can be adjusted synchronously. The telescopic assembly 3 includes a fixed seat 32 and a bidirectional telescopic rod 31, the fixed seat 32 is respectively installed on the inner side wall of the top plate 11 and the bottom plate 12, and the two ends of the bidirectional telescopic rod 31 are hinged with the fixed seat 32 through a pin shaft. The piston rod of the bidirectional telescopic rod 31 is connected with the telescopic frame 2 through an L-shaped connector, the vertical segment of the L-shaped connector is fixedly connected with the telescopic frame 2, and the horizontal segment is slidably connected with the sliding groove 15 of the main frame 1 through a sliding block.
[0033] The sliding grooves 15 are formed on the top plate 11 and the bottom plate 12 of the main frame 1, and the dovetail groove structure is preferably adopted in the present embodiment, which can effectively prevent the connector from tilting during movement. The sliding grooves 15 extend along the length direction of the main frame 1, and the length thereof matches the maximum telescopic stroke of the telescopic frame 2. The outer surface of the telescopic frame 2 and the inner wall of the main frame 1 are coated with a composite coating, which includes a rust-proof bottom layer, a wear-resistant intermediate layer and a corrosion-resistant surface layer in sequence, which can significantly improve the corrosion resistance and wear resistance of the frame.
[0034] When the length of the frame needs to be adjusted, the bidirectional telescopic rod 31 is activated to drive the piston rod to extend, and through the L-shaped connecting piece, the telescopic frame 2 is synchronously moved to both sides along the sliding groove 15. Due to the symmetrical double telescopic frame structure, the stability of the frame during telescoping can be ensured. After telescoping to the required length, the hydraulic lock of the bidirectional telescopic rod 31 is automatically locked to ensure that the frame remains fixed during transportation.
[0035] The present embodiment can realize stepless adjustment of the length of the frame through the symmetrical double telescopic frame structure and the bidirectional driving telescopic assembly, and meet the transportation needs of goods of different sizes. The setting of the buffer pad 14 and the composite coating effectively improves the carrying capacity and service life of the frame, and is particularly suitable for heavy-load transportation scenes such as ports and logistics centers.
[0036] The above is only to illustrate the present application, and it should be understood that the present application is not limited to the above embodiments, and various modifications in accordance with the present application are within the scope of the present application.
