Description

Technical Field

[0001] The utility model belongs to the technical field of excavators, and in particular relates to a radiator inspection window for a mining excavator. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] An excavator is an earth-moving machine that uses a bucket to dig materials above or below the surface of the machine and load them into a transport vehicle or unload them to a stockpile. A radiator is installed on the excavator, and the radiator is equipped with a corresponding radiator inspection window to facilitate radiator inspection.

[0004] At present, most of the heat dissipation windows of radiators are grille-type structures, which cannot effectively prevent foreign matter (sand and gravel, etc.) in the air from entering the radiator, affecting the heat dissipation efficiency. Some also use shutter structures as heat dissipation windows. Although this structure improves the heat dissipation effect, it cannot effectively prevent sand and gravel from entering the radiator. In particular, the working environment of mining excavators is special. It is inevitable that ore fragments will collapse during work, and the shutter structure is difficult to play a good protective role. In addition, most of the current heat dissipation nets are welded, which are prone to welding defects. The welding parts tend to crack more after vibration, resulting in the failure of the protective net. If replacement is required, it can only be replaced as a whole, which increases the cost of use.

[0038] It should be noted that the following detailed descriptions are all exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0039] The following is a detailed description of the utility model with reference to the accompanying drawings. The present embodiment discloses a radiator inspection window for a mining excavator, such as Figure 1 As shown, it comprises a mounting frame 1, a first side beam 2 is arranged at one end of the mounting frame 1, and a second side beam 9 is arranged at the other end; a cross beam 3 is arranged at the front and rear parts between the first side beam 2 and the second side beam 9, and a middle beam 4 is arranged at the middle part; a heat dissipation mechanism 5 is arranged between the cross beam 3 and the middle beam 4;

[0040] like Figure 2 As shown, the heat dissipation mechanism 5 includes a first heat dissipation mesh plate 51 and a second heat dissipation mesh plate 54, the first heat dissipation mesh plate 51 and the second heat dissipation mesh plate 54 are connected by a second heat dissipation connecting plate 53, and a first heat dissipation connecting plate 52 is arranged at one end of the second heat dissipation connecting plate 53; a plurality of first heat dissipation mesh plates 51 and second heat dissipation mesh plates 54 are alternately arranged, and meshes are provided on the first heat dissipation mesh plates 51 and the second heat dissipation mesh plates 54.

[0041] When the excavator is working, the sand and gravel will collapse from any direction onto the inspection window. If a grille structure is used, the holes on its surface are relatively large, and the sand and gravel can easily collapse into the radiator. If a shutter structure is used, the sand and gravel will collapse into the radiator from the oblique bottom. In this regard, the utility model uses the second heat dissipation connecting plate 53 to place the first heat dissipation mesh plate 51 and the second heat dissipation mesh plate 54 in different planes. The second heat dissipation mesh plate 54 is concave, so that the second heat dissipation connecting plate 53 protects the sand and gravel that collapses from the oblique direction. The mesh apertures on the first heat dissipation mesh plate 51 and the second heat dissipation plate are small and densely distributed, which can ensure the heat dissipation effect and prevent sand and gravel from entering the radiator through the mesh holes.

[0042] The working environment of the excavator is special, and it is easy to be bumped and vibrated. The long-term vibration of welding will cause cracking. In this regard, the heat dissipation mechanism 5 of the utility model is an integrated structure, which can be stamped and then punched, and the overall strength is high.

[0043] A plurality of second mounting holes 56 are arranged at intervals on the first heat dissipation connection plate 52, and square grooves are arranged between the second mounting holes 56. The second mounting holes 56 are used to connect the first heat dissipation connection plate 52 with the cross beam 3 and the middle beam 4. Heat dissipation mechanisms 5 are arranged at both ends of the middle beam 4, and the square grooves of the heat dissipation mechanisms 5 at both ends are aligned, thereby reserving a position for the installation of the opening and closing mechanism 6. Square protrusions are arranged at both ends of the second heat dissipation mesh plate 54, and first mounting holes 55 are arranged on the square protrusions. The first mounting holes 55 are used to connect the second heat dissipation mesh plate 54 with the side beams.

[0044] like Figure 3 As shown, hinge reserved grooves 11 are arranged at intervals at one end of the mounting frame 1, and lock holes 12 are arranged at intervals at the other end of the mounting frame 1; a heat dissipation reserved hole 13 is arranged in the middle of the mounting frame 1. The hinge reserved groove 11 provides a reserved space for the installation of the hinge 8; the heat dissipation reserved hole 13 is a square hole, so that the mesh of the heat dissipation mesh plate is in contact with the outside.

[0045] like Figure 4 As shown, the first side beam 2 is an integrated structure, and the first side beam 2 includes a side beam body 21, a first connecting plate 22 is arranged at one end of the side beam body 21, and a second connecting plate 23 is arranged at the other end of the side beam body 21. The first connecting plate 22 is arranged on the upper part of the mounting frame 1, so that there is a certain distance between the side beam body 21 and the inner side surface of the mounting frame 1, providing space for the installation of the hinge 8, so that the hinge 8 is protected by the mounting frame 1, and the hinge 8 is prevented from being impacted by sand and stones. One end of the first heat dissipation mesh plate 51 is arranged on the upper part of the second connecting plate 23, and the second connecting plate 23 provides support for the first heat dissipation mesh plate 51, which is convenient for the installation or removal of the heat dissipation mechanism 5.

[0046] Hinge mounting holes 24 are arranged at intervals on the upper surface of the side beam body 21, and first heat dissipation mounting holes 25 are arranged at intervals at one end of the hinge mounting holes 24; the first side beam 2 and the second side beam 9 are connected to the second heat dissipation mesh plate 54 by bolts. The hinge mounting holes 24 are used to fix one end of the hinge 8 on the side beam body 21; the first heat dissipation mounting holes 25 are used to connect the second heat dissipation mesh plate 54 to the side beam.

[0047] like Figure 5 As shown, the second side beam 9 includes a side beam body 21, a second connecting plate 23, a hinge mounting hole 24 and a first heat dissipation mounting hole 25, and the functions of each component are the same as those of the first side beam 2. Figure 6As shown, second heat dissipation mounting holes 31 are arranged at intervals on the upper surface of the crossbeam 3 ; the crossbeam 3 and the second heat dissipation connecting plate 53 of the heat dissipation mechanism 5 are connected by bolts.

[0048] like Figure 7 As shown, the upper surface of the middle beam 4 is provided with third heat dissipation mounting holes 42 at intervals, and the middle beam 4 is connected to the second heat dissipation connecting plate 53 of the heat dissipation mechanism 5 by bolts; a base mounting hole 41 is provided at one end of the upper surface of the middle beam 4. The base mounting hole 41 is used to install the base 61 of the opening and closing mechanism 6.

[0049] like Figure 8 As shown, an opening and closing mechanism 6 is arranged on the upper part of the middle beam 4, and the opening and closing mechanism 6 comprises a base 61, a special-shaped hole 611 is arranged on the base 61, and a second connecting column is arranged in the special-shaped hole 611; a connecting plate 65 is arranged at one end of the second connecting column, and a moving plate 62 is arranged at the other end; a first connecting column 63 is arranged at one end of the moving plate 62. When in use, as the moving plate 62 rotates, the second connecting column 64 slides along the special-shaped hole 611, and then cooperates with the hinge 8 to assist the inspection window to open or close.

[0050] like Figure 1 As shown, a plurality of hinges 8 are arranged at intervals on the first side beam 2, a plurality of locking blocks 7 are arranged at intervals on the second side beam 9, a through hole is arranged on the locking block 7, and the through hole of the locking block 7 is aligned with the locking hole 12 of the mounting frame 1. The hinge 8 is used for opening and closing the inspection window. After the inspection window is closed, a bolt is passed through the locking hole 12 and the through hole of the locking block 7 to lock the inspection window, and the inspection window is opened when the inspection window is in operation.

[0051] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
