Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to an air filter installation structure and engineering machinery. Background Technology

[0002] There are generally three ways to arrange air filters in underground mining equipment: the first is to fix the air filter to the mudguard through a transition bracket without protection; the second is to arrange the air filter directly above the engine through a transition bracket, with the rain cap exposed to the outside of the engine hood, and the air filter housing and the engine are both inside the engine hood; the third is to fix the air filter to the frame through a transition bracket, with both the air filter and the bracket inside the engine hood.

[0003] The shortcomings of existing technologies are as follows: The first air filter arrangement, being exposed to the outside of the machine, is easily damaged by the underground mine walls or loose rocks; the second air filter arrangement requires a large space to install, and because the air filter is directly connected to the engine, it is prone to resonance, leading to support failure and excessive air filter swaying; the third air filter arrangement, with the transition support designed below the air filter, occupies a large space and is therefore unsuitable for underground mining equipment. Furthermore, the dust discharge ports of all three schemes discharge dust directly downwards, easily contaminating the components below and creating cleaning difficulties. Utility Model Content

[0004] The purpose of this utility model is to provide an air filter installation structure and engineering machinery to solve the problems of difficult air filter arrangement and limited internal space in existing underground mining equipment.

[0005] To achieve the above objectives, the present invention provides an air filter installation structure, including a hood. Inside the hood are an air filter body, a fixing bracket, and a frame crossbeam. The air filter body extends axially forward and backward. The fixing bracket is located below the front of the air filter body. The frame crossbeam is located in front of the air filter body and the fixing bracket. The fixing bracket is an arch-shaped fixing bracket structure, with its inner wall facing downwards from the air filter body. The outer wall of the upper rear end of the fixing bracket is connected and fixed to the bottom wall of the air filter body, and the outer wall of the lower front end of the fixing bracket is connected and fixed to the inner wall of the frame crossbeam. The path length of the fixing bracket extends in a curved manner from the air filter body to the frame crossbeam. An air filter rain cap is provided on the outside of the hood. The hood has a connecting hole. The air filter body, the connecting hole, and the air filter rain cap are arranged sequentially from bottom to top. The top wall of the air filter body is connected to the air filter rain cap via a connecting pipe, which passes through the connecting hole.

[0006] Furthermore, the fixed bracket includes two bow-shaped arms distributed along the left and right sides, two connecting rods distributed along the front and back sides are provided between the upper rear ends of the two bow-shaped arms, and two connecting rods distributed along the top and bottom sides are provided between the lower front ends of the two bow-shaped arms.

[0007] Furthermore, the inner wall of the fixed bracket is provided with a reinforcing rod, and the two ends of the reinforcing rod are respectively connected and fixed to the connecting rod at the upper rear end and the connecting rod at the lower front end.

[0008] Furthermore, the bow-shaped arm, the connecting rod, and the reinforcing rod are steel pipes with a rectangular cross-section, and the fixed bracket is formed by welding together several of the steel pipes.

[0009] Furthermore, the upper rear end and upper front end of the two bow-shaped arms are provided with a number of connecting holes, which can be locked with screws; a number of mounting blocks are provided between the upper rear ends of the two bow-shaped arms, and the connecting rod at the upper rear end is located in front of the mounting block at the upper rear end. One of the bow-shaped arms is provided with a number of mounting blocks, and the mounting blocks are provided with mounting holes.

[0010] Furthermore, a dust collection hopper is fixedly installed at the upper rear end of the fixed bracket, and the dust collection hopper is located below the air filter dust discharge port of the air filter body.

[0011] Furthermore, the air filter body is arranged in front of the mudguard, and the air filter maintenance port of the air filter body faces the outer opening of the hood.

[0012] Furthermore, the connecting pipe includes a rubber corrugated pipe and a sleeve support connected sequentially from bottom to top. The sleeve support passes through the connecting hole, and the side plate of the sleeve support is installed and fixed to the machine cover.

[0013] Furthermore, a pre-filter is connected between the air filter rain cap and the sleeve support. A pre-filter protective cover is provided above the air filter rain cap. The three sides of the pre-filter protective cover are provided with downwardly bent fixing plates. The fixing plates are fixedly connected to the machine cover. Ventilation ports are provided on the two opposite fixing plates.

[0014] This utility model also provides an engineering machinery, including a main body of the engineering machinery and an air filter mounting structure as described in any of the above technical solutions, wherein the air filter mounting structure is disposed on the main body of the engineering machinery.

[0015] In summary, the application of the technical solution of this utility model has the following beneficial effects: The structural design of this utility model is reasonable. (1) By setting up a cover, the inside of the cover is provided with an air filter body, a fixed bracket, and a frame beam. The axial direction of the air filter body extends along the front and rear. The fixed bracket is set at the lower front of the air filter body. The frame beam is set in front of the air filter body and the fixed bracket. The fixed bracket is an arc-shaped fixed bracket structure. The inner wall of the fixed bracket faces the lower part of the air filter body. The outer wall of the upper rear end of the fixed bracket is connected and fixed to the bottom wall of the air filter body. The outer wall of the lower front end of the fixed bracket is connected and fixed to the inner wall of the frame beam. The path length of the fixed bracket extends from the air filter body to the frame beam in a curved manner. Thus, the air filter body is fixed to the frame beam through the arc-shaped fixed bracket structure. Since the arc-shaped fixed bracket structure does not occupy the space below the air filter body, the space below the air filter body can be used to arrange other components. (2) By setting an air filter rain cap on the outside of the housing, and a connecting hole on the housing, the air filter body, the connecting hole, and the air filter rain cap are arranged sequentially from bottom to top. The top wall of the air filter body and the air filter rain cap are connected by a connecting pipe, which passes through the connecting hole; thus, the air filter body inside the housing and the air filter rain cap outside the housing are connected by the connecting pipe for gas communication. As can be seen from the above analysis, since the bow-shaped fixed bracket structure of this utility model does not occupy the space below the air filter, the space below the air filter can be used to arrange other components, thereby improving the space utilization rate inside the housing.

[0019] See Figures 1 to 5This embodiment provides an air filter installation structure, including a hood 6. Inside the hood 6 are an air filter body 3, a fixing bracket 1, and a frame crossbeam 7. The air filter body 3 extends axially along the front and rear. The fixing bracket 1 is located at the lower front of the air filter body 3. The frame crossbeam 7 is located in front of the air filter body 3 and the fixing bracket 1. The fixing bracket 1 is an arc-shaped fixing bracket structure. The inner wall of the fixing bracket 1 faces the lower part of the air filter body 3. The outer wall of the upper rear end of the fixing bracket 1 is connected and fixed to the bottom wall of the air filter body 3. The outer wall of the lower front end of the fixing bracket 1 is connected and fixed to the inner wall of the frame crossbeam 7. The path length of the fixing bracket 1 bends and extends from the air filter body 3 to the frame crossbeam 7. An air filter rain cap 5 is provided on the outside of the hood 6. The hood 6 has a connecting hole 601. The air filter body 3, the connecting hole 601, and the air filter rain cap 5 are arranged sequentially from bottom to top. The top wall of the air filter body 3 and the air filter rain cap 5 are connected by a connecting pipe 8, which passes through the connecting hole 601. Function: (1) By setting up a hood, the inside of the hood is provided with an air filter body, a fixed bracket, and a frame crossbeam. The axial direction of the air filter body extends along the front and rear. The fixed bracket is set at the lower front of the air filter body. The frame crossbeam is set in front of the air filter body and the fixed bracket. The fixed bracket is an arc-shaped fixed bracket structure. The inner wall of the fixed bracket faces the lower part of the air filter body. The outer wall of the upper rear end of the fixed bracket is connected and fixed to the bottom wall of the air filter body. The outer wall of the lower front end of the fixed bracket is connected and fixed to the inner wall of the frame crossbeam. The path length of the fixed bracket bends and extends from the air filter body to the frame crossbeam. Thus, the air filter body is fixed to the frame crossbeam through the arc-shaped fixed bracket structure. Since the arc-shaped fixed bracket structure does not occupy the space below the air filter body, the space below the air filter body can be used to arrange other components. (2) By setting an air filter rain cap on the outside of the housing, and a connecting hole on the housing, the air filter body, the connecting hole, and the air filter rain cap are arranged sequentially from bottom to top. The top wall of the air filter body and the air filter rain cap are connected by a connecting pipe, which passes through the connecting hole; thus, the air filter body inside the housing and the air filter rain cap outside the housing are connected by the connecting pipe for gas communication. As can be seen from the above analysis, since the bow-shaped fixed bracket structure of this utility model does not occupy the space below the air filter, the space below the air filter can be used to arrange other components, thereby improving the space utilization rate inside the housing.

[0020] Specifically, the fixed bracket 1 includes two bow-shaped arms 101 distributed along the left and right sides, two connecting rods 102 distributed along the front and rear sides between the upper rear ends of the two bow-shaped arms 101, and two connecting rods 102 distributed along the vertical sides between the lower front ends of the two bow-shaped arms 101. Function: Through the cooperation of the bow-shaped arms 101 and the connecting rods 102, the overall structure of the fixed bracket 1 is formed.

[0021] Specifically, the inner wall of the fixed bracket 1 is provided with a reinforcing rod 103, and both ends of the reinforcing rod 103 are connected and fixed to the connecting rod 102 at the upper rear end and the connecting rod 102 at the lower front end, respectively. Function: The reinforcing rod improves the overall support strength of the fixed bracket 1.

[0022] Specifically, the bow-shaped arm 101, connecting rod 102, and reinforcing rod 103 are all steel pipes with rectangular cross-sections, and the fixed bracket 1 is formed by welding together several steel pipes. Function: The bow-shaped fixed bracket structure formed by welding together rectangular steel pipes has high strength and rigidity, improving reliability and thus enhancing the overall connection strength of the fixed bracket 1.

[0023] Specifically, the upper rear and upper front ends of the two bow-shaped arms 101 are provided with several connecting holes 104, which can be locked with screws 9; several mounting blocks 105 are provided between the upper rear ends of the two bow-shaped arms 101, and the connecting rod 102 at the upper rear end is located in front of the mounting block 105 at the upper rear end. One of the bow-shaped arms 101 is provided with several mounting blocks 105, and the mounting blocks 105 are provided with mounting holes. Function: The connecting holes 104 at the upper rear and upper front ends can be screwed and fixed to the air filter body 3 and the frame crossbeam 7, respectively, while the mounting blocks 105 facilitate the installation of other components.

[0024] Specifically, a dust collection hopper 2 is fixedly installed at the upper rear end of the fixed bracket 1, and the dust collection hopper 2 is located below the air filter dust discharge port of the air filter body 3. Function: This solution uses a dust collection hopper for dust collection and discharge, preventing dust from falling directly onto the surface of the components below. Cleaning can be done by simply removing the dust collection hopper. Additionally, due to the high dust levels in underground working conditions, large amounts of dust can be discharged by cleaning the dust collection hopper.

[0025] Specifically, the air filter body 3 is arranged in front of the mudguard, and the air filter maintenance port of the air filter body 3 faces the outer opening of the hood 6. Function: Since the air filter body 3 is arranged inside the hood and in front of the mudguard, the air filter maintenance port of the air filter body 3 faces outward, making it convenient to maintain and replace the filter element.

[0026] Specifically, the connecting pipe 8 includes a rubber corrugated pipe 801 and a sleeve support 802 connected sequentially from bottom to top. The sleeve support 802 passes through the connecting hole 601, and the side plate 803 of the sleeve support 802 is fixed to the housing 6. Function: Since the air filter rain cap is installed on the outside of the housing, it is connected to the air filter body through the rubber corrugated pipe and the sleeve support 802. The installation of the sleeve support 802 on the housing can achieve a stable connection between the air filter rain cap and the air filter body.

[0027] Specifically, a pre-filter is connected between the air filter rain cap 5 and the casing support 802. A pre-filter protective cover 4 is provided above the air filter rain cap 5. The three sides of the pre-filter protective cover 4 are provided with downwardly bent fixing plates 401. The fixing plates 401 are fixedly connected to the machine cover 6. Ventilation ports 402 are provided on the two opposite fixing plates 401. Function: By adding the pre-filter protective cover, the air filter rain cap 5 is prevented from being damaged by gravel, and the pre-filter or the rain cap is prevented from being damaged by falling gravel in the harsh underground environment.

[0028] This utility model also provides an engineering machinery, including a main body of the engineering machinery and an air filter mounting structure according to any of the above-mentioned technical solutions, wherein the air filter mounting structure is disposed on the main body of the engineering machinery. Function: The air filter mounting structure can be applied to the design of air filter layout schemes for underground mining equipment (such as loaders and other engineering machinery). As can be seen from the above description, this utility model improves the utilization rate and maintainability of the space inside the engine hood. Furthermore, since no other components are fixed above the engine, the overall height of the equipment can be greatly reduced, further increasing the driver's visibility and improving safety.

[0029] In summary, the air filter arrangement of this utility model not only improves the service life of the air filter and enhances maintenance convenience, but also makes reasonable use of the limited space inside the machine hood, facilitating the arrangement of other components and improving space utilization, making underground mining equipment more compact; and providing more design options for the design of underground mining equipment.

[0030] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
