Description

Technical Field

[0001] This utility model relates to the field of bulldozer technology, specifically to a wing plate structure for a bulldozer containing support components. Background Technology

[0002] Bulldozer wing plates are important structural components of bulldozers, mainly used to support the cab and protect the operators. Heavy components such as the bulldozer's fuel tank and hydraulic oil tank are also usually directly mounted on the wing plates, making the total weight of the wing plates and their accessories quite large. This inevitably requires the wing plates to have higher strength and load-bearing capacity.

[0003] The existing bulldozer blade structure is made of steel plate sheet metal parts assembled and welded. Under high vibration conditions, the joints at the installation positions of the fuel tank and hydraulic oil tank are prone to cracking or even breakage, which poses a great safety hazard to the operation of the bulldozer.

The front protective plate 2 and the rear protective plate 7 are respectively disposed at two ends of the profile plate 1. The first protective plate 3 and the second protective plate 4 are connected by a first support plate 8 and are disposed on the profile plate 1 at a position away from the rear protective plate 7. The third protective plate 5 is connected to the second protective plate 4 by a first connector 9. The second protective plate 4 and the third protective plate 5 are disposed in the middle position of the profile plate 1. The first protective plate 3 and the second protective plate 4... A support component 60 is provided between them. The fourth protective plate 6 is connected to the front protective plate 2. The front protective plate 2 is a bent plate with a triangular shape at the bend. The first protective plate 3, the second protective plate 4, the third protective plate 5 and the fourth protective plate 6 divide the outline plate 1 into a first mounting part 10, a second mounting part 20 and a third mounting part 30. The first mounting part 10 is used to install the bulldozer's fuel tank, hydraulic oil tank, etc. An inner support component 40 is provided inside the first mounting part 10. An outer support component 50 is provided on the back of the first mounting part 10. The third mounting part 20 is used to install the electrical control box, which contains the bulldozer's electrical control components.

[0025] In this embodiment, as Figure 5 As shown, the contour plate 1 includes a base plate 11, an outer plate 12, a back plate 13, a first connecting plate 14, and a second connecting plate 15. One side of the base plate 11 is connected to the outer plate 12 through the first connecting plate 14, and the other side is connected to the back plate 13 through the second connecting plate 15. Both the first connecting plate 14 and the second connecting plate 15 are arc-shaped. The outer plate 12 is installed vertically downward on one side of the base plate 11, and the back plate 13 is installed vertically upward on the other side of the base plate 11. One end of the back plate 13 is connected to the first protective plate 3, and one end of the third protective plate 4 abuts against the surface of the back plate 13. A baffle 131 of a certain height is milled out from the end of the back plate 13 away from the first mounting part 10. The height of the third protective plate 5 is the same as the height of the baffle 131.

[0026] In this embodiment, as Figure 1 and 3As shown, the first mounting part 10 is a box-shaped frame structure, which is welded to the bottom plate 11, back plate 13, first protective plate 3 and rear protective plate 7 through the fuel tank mounting plate 16 to form an integral frame structure. The fuel tank mounting plate 16 is a whole L-shaped plate, including an upper fuel tank mounting plate 161, a lower fuel tank mounting plate 162 and a third connecting plate 163. The lower fuel tank mounting plate 162 is connected to the upper fuel tank mounting plate 162 through the third connecting plate 163. The lower fuel tank mounting plate 162 is parallel to the outer plate 12 and perpendicular to the upper fuel tank mounting plate 161. The upper fuel tank mounting plate 162 includes a first fitting part 1611, a second fitting part 1612 and a third fitting part 1613. Auxiliary mounting holes 1614 are respectively provided at the first fitting part 1611 and the second fitting part 1612. 161 is attached to the protrusion 132 on the back plate 13 and the rear protective plate 7 through the auxiliary mounting hole 1614. The third fitting part is connected to the first protective plate 3 to prevent the wing plate from tilting outward under the weight of the fuel tank, causing the wing plate to crack or even tear. The box-shaped frame structure has an internal support component 40 arranged horizontally inside. The overall box-shaped frame structure has internal fillet welds and external plug welds. The internal support component 40 includes two sets of internal reinforcing ribs 41. The internal reinforcing ribs 41 are rectangular steel plates. The bottom of the internal reinforcing ribs 41 is in contact with the bottom plate 11, the top is in contact with the upper fuel tank mounting plate 161, one wide side is in contact with the back plate 13, and the other wide side is in contact with the lower fuel tank mounting plate 162. The lower fuel tank mounting plate 162 has several screw holes 1621.

[0027] In this embodiment, as Figure 2 and 4 As shown, the outer support assembly 50 is installed on the back of the first mounting part 10, that is, on the bottom of the contour plate 1. The outer support assembly 50 includes three sets of outer reinforcing ribs 51 and two sets of fasteners 52. The outer reinforcing ribs 51 include a first rib 511, a second rib 512, and a rib connecting plate 513. The first rib 511 and the second rib 512 are connected by the rib connecting plate 513. The first rib 511 and the second rib 512 are both right-angled triangles. Taking the first rib 511 as an example, the two right-angled sides of the first rib 511 are respectively connected to the bottom plate 11 and the outer plate 12. The contact connection is used to reinforce and support the fuel tank or hydraulic tank under high load due to the cantilever structure, thus playing a cantilever support role. The fastener 52 includes a bolt 521, a washer 522, a nut 523, and a pad 524. The washer 522 has a ring hole 5221, and the pad 524 has a small round hole 5241. The ring hole 5221 and the small round hole 5241 correspond to the screw hole 1621. The bolt 521 passes through the small round hole 5241, the screw hole 1621, and the ring hole 5221, and is fixed with the nut 523 to install and connect the outer plate 12 to the lower oil tank mounting plate 162.

[0028] This embodiment discloses a wing plate structure 100 for a bulldozer. This wing plate structure, at the first mounting part 10 where the fuel tank and hydraulic oil tank are installed, combines a contour plate 1, a rear protective plate 7, and a fuel tank mounting plate 16 to form a box-shaped frame structure. Two sets of internal reinforcing ribs 41 are provided within this structure, and external reinforcing ribs 51 are provided on the back of the contour plate 1. This prevents the wing plate structure from cracking or even breaking under heavy load and high vibration conditions, thereby improving the overall strength of the first mounting part 10 where the fuel tank and hydraulic oil tank are installed, and thus enhancing the overall reliability and safety of the bulldozer.
