Description

Technical Field

[0001] This utility model belongs to the field of excavator technology, and in particular relates to a protective cover for the exhaust pipe of a mining excavator. Background Technology

[0002] Mining excavators are hydraulically driven engineering machines specifically designed for mining operations. They are primarily used for stripping and loading operations in open-pit mines and possess large-tonnage loading capabilities. The excavator's exhaust pipe is a crucial component of the exhaust system, responsible for safely discharging exhaust gases from the engine into the atmosphere.

[0003] Because the surface of the mine is often uneven, to prevent damage to the exhaust pipe caused by the excavator's movement during operation, the exhaust pipe is usually placed above the engine compartment and is often exposed. This poses a risk of burns to personnel performing maintenance during engine startup if they are working on the exhaust pipe. Furthermore, excavators, especially mining excavators, typically operate outdoors, and prolonged exposure to sun, wind, and rain can easily cause the exhaust pipe to rust and perforate, creating a potential for corrosion and leaks. Utility Model Content

[0004] In view of the defects or deficiencies in the existing technology, this utility model provides a protective cover for the exhaust pipe of a mining excavator, which can effectively protect the exhaust pipe of the excavator and improve the safety and service life of the exhaust pipe.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An embodiment of this utility model provides a protective cover for the exhaust pipe of a mining excavator, including a surrounding plate, side plates, partitions, and a mounting plate. The partitions are located behind the surrounding plate, and the two sides of the surrounding plate and the partitions are connected by the side plates. The surrounding plate, side plates, and partitions are fixed to the outside of the excavator exhaust pipe by the mounting plate, and all are spaced at a set distance from the excavator exhaust pipe.

[0007] Furthermore, the enclosure is made of bent steel plate, and its shape is adapted to the shape of the front side of the excavator's exhaust pipe.

[0008] Furthermore, the enclosure includes a flat plate, a vertical plate, and a connecting plate. The flat plate is located above the vertical plate and is perpendicular to the vertical plate. The top end of the vertical plate is connected to the end of the flat plate near the vertical plate through the connecting plate, and the connecting plate is inclined.

[0009] Furthermore, the partition is made of bent steel plate, and the shape of the partition is the same as the rear side of the excavator exhaust pipe.

[0010] Furthermore, the partition includes a first vertical section, a connecting section, and a second vertical section, which are connected by the connecting section and are inclined.

[0011] Furthermore, the top end of the first vertical segment is welded and fixed to the side of the plate away from the connecting plate, and the first vertical segment is perpendicular to the plate.

[0012] Furthermore, the second vertical segment is located behind the vertical plate and is spaced a certain distance from the vertical plate, with the bottom end of the second vertical segment flush with the bottom end of the vertical plate.

[0013] Furthermore, a first mounting opening is provided on the upper part of the partition, and the first mounting opening is opened on the first vertical section and the connecting section.

[0014] Furthermore, the shapes of the two sides of the side plate correspond to those of the surrounding plate and the partition plate, respectively. The top and bottom ends of the side plate are both horizontally set. The top end of the side plate is welded and fixed to the flat plate, and the bottom end of the side plate is flush with the bottom edge of the surrounding plate and the partition plate.

[0015] Furthermore, the mounting plate is horizontally positioned and welded to the bottom edge of the surrounding plate, partition plate, and side plate. A second mounting hole is provided in the middle of the mounting plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model, by setting up a surrounding plate, side plate, partition plate, and mounting plate, fixes the surrounding plate, side plate, and partition plate to the outside of the excavator exhaust pipe through the mounting plate, and the surrounding plate, side plate, and partition plate are spaced at a set distance from the excavator exhaust pipe. In this way, the excavator exhaust pipe is protected without affecting the heat dissipation of the excavator exhaust pipe. This can effectively prevent scalding of maintenance personnel due to excessive temperature during engine start-up, and also prevent corrosion caused by prolonged exposure to the outside, thereby improving the safety and service life of the excavator exhaust pipe.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] A typical embodiment of this utility model is as follows: Figure 1 and Figure 2 As shown, a protective cover for the exhaust pipe of a mining excavator includes a surrounding plate 1, a side plate 2, a partition plate 3, and a mounting plate 4. The partition plate 3 is located behind the surrounding plate 1. The two sides of the surrounding plate 1 and the partition plate 3 are connected by the side plate 2. The surrounding plate 1, the side plate 2, and the partition plate 3 are fixed to the outside of the excavator exhaust pipe 6 by the mounting plate 4, and all of them are spaced at a set distance from the excavator exhaust pipe 6, thereby protecting the excavator exhaust pipe 6 without affecting the heat dissipation of the excavator exhaust pipe 6.

[0024] Specifically, the enclosure 1 is made of bent steel plate. The shape of the enclosure 1 is adapted to the shape of the front side of the excavator exhaust pipe 6. It includes a flat plate 11, a vertical plate 12 and a connecting plate 13. The flat plate 11 is located above the vertical plate 12 and is set perpendicular to the vertical plate 12. The top of the vertical plate 12 is connected to the end of the flat plate 11 near the vertical plate 12 through the connecting plate 13. The connecting plate 13 is set at an angle so that the flat plate 11 and the vertical plate 12 are spaced apart by a set distance in both the horizontal and vertical directions.

[0025] In use, the enclosure 1 is fixed to the front side of the excavator exhaust pipe 6. Since the excavator exhaust pipe 6 extends vertically upward and bends backward at the top, the vertical plate 12 is located in front of the vertical section of the exhaust pipe and is spaced at a set distance from the vertical section of the exhaust pipe, thereby protecting the front side of the vertical section of the exhaust pipe. The flat plate 11 is located above the top of the exhaust pipe and is spaced at a set distance from the top of the exhaust pipe, thereby protecting the top of the exhaust pipe. At this time, the connecting plate 13 is located outside the curved section of the exhaust pipe and is spaced at a set distance from the curved section of the exhaust pipe, for the purpose of protecting the curved section of the exhaust pipe.

[0026] The partition 3 is made of bent steel plate, and its shape is adapted to the rear shape of the excavator exhaust pipe 6. It includes a first vertical section 31, a connecting section 32, and a second vertical section 33. The first vertical section 31 and the second vertical section 33 are connected by the connecting section 32. The top of the first vertical section 31 is welded and fixed to the side of the plate 11 away from the connecting plate 13, and the first vertical section 31 is perpendicular to the plate 11. The second vertical section 33 is located behind the vertical plate 12 and is spaced a certain distance from the vertical plate 12. The bottom end of the straight section 33 is flush with the bottom end of the vertical plate 12. The height of the second vertical section 33 is less than the height of the vertical plate 12. The first vertical section 31 and the second vertical section 33 are connected by a connecting section 32, and the connecting section 32 is inclined so that the first vertical section 31 and the second vertical section 33 are spaced apart by a set distance in the horizontal and vertical directions, thereby conforming to the rear structure of the excavator exhaust pipe 6. A first mounting port 34 is provided on the upper part of the partition plate 3. The first mounting port 34 is located on the first vertical section 31 and the connecting section 32.

[0027] By setting the first mounting port 34, on the one hand, it is convenient to put the protective cover on the outside of the excavator exhaust pipe 6, and on the other hand, when the protective cover is put on the outside of the excavator exhaust pipe 6, it is convenient for the exhaust pipe to exhaust from the first mounting port.

[0028] There are two side panels 2, which are respectively set on both sides of the enclosure 1 and the partition 3. The shapes of the two sides of the side panel 2 correspond to the enclosure 1 and the partition 3, so as to facilitate the welding and fixing of the two sides of the side panel 2 to the enclosure 1 and the partition 3 respectively. The top and bottom ends of the side panel 2 are both set horizontally. The top end of the side panel 2 is welded and fixed to the flat plate 11, and the bottom end of the side panel 2 is flush with the bottom edge of the enclosure 1 and the partition 3.

[0029] The bottom ends of the enclosure 1, partition 3 and side plate 2 are joined to form a rectangular mounting opening. The mounting plate 4 is set horizontally, and a second mounting hole is opened in the middle of the mounting plate 4. The second mounting hole is adapted to the rectangular mounting opening. The mounting plate 4 is welded and fixed to the bottom edge of the enclosure 1, partition 3 and side plate 2 so that the second mounting hole and the rectangular mounting hole correspond to each other.

[0030] The mounting plate 4 has multiple bolt holes 41 on both sides, which can be fixed to the excavator cover by bolts, so that the protective cover can be easily disassembled and replaced after it is damaged.

[0031] Furthermore, a lifting lug 5 is provided at the upper edge of the side panel 2 to facilitate the installation and removal of the protective cover.

[0032] When using, such as Figure 3 As shown, the bottom end of the exhaust pipe passes through the second mounting port on the mounting plate 4, and the exhaust end of the exhaust pipe exhausts through the second mounting port 34 on the upper part of the partition 3. Since both the enclosure plate 1 and the partition 3 are made of steel plate bent, the bending angle can be adjusted according to the shape of the exhaust pipe, so that the shape of the protective cover fits the shape of the exhaust pipe better, effectively protecting the exhaust pipe, while reserving heat dissipation space to avoid the exhaust pipe temperature from being too high.

[0033] Furthermore, the exterior of the protective cover is coated with a high-temperature resistant paint with a heat resistance temperature of not less than 600℃, thereby improving the high-temperature resistance of the protective cover.

[0034] By installing enclosures, side panels, partitions, and mounting plates, which are fixed to the outside of the excavator's exhaust pipe via the mounting plates, and with a set distance between the enclosures, side panels, and partitions and the excavator's exhaust pipe, the excavator's exhaust pipe is protected without affecting its heat dissipation. This effectively prevents burns to maintenance personnel due to excessive temperature during engine startup and avoids corrosion caused by prolonged exposure, thus improving the safety and service life of the excavator's exhaust pipe.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
