Abstract
Description
Technical Field
[0001] This utility model belongs to the field of excavator technology, specifically relating to an excavator walking frame that facilitates track maintenance. Background Technology
[0002] The excavator's engine transmits power to the drive wheels via a transmission system. The rotation of the drive wheels drives the track links, and the friction between the tracks and the ground allows the excavator to move on the ground. Simultaneously, by controlling the speed and direction of the drive wheels, the excavator can move forward, backward, and turn.
[0003] In the field of construction machinery, equipment such as excavators and bulldozers often operate under complex and harsh conditions. Tracks, as critical walking components, are highly susceptible to accumulating large amounts of sand and soil mixtures. Traditional track cleaning methods mainly include manual cleaning and simple flushing equipment. Manual cleaning is not only labor-intensive and time-consuming, but also inefficient, and the cleaning effect is difficult to guarantee. For some tightly adhered sand and soil mixtures, it is difficult to completely remove them. If these mixtures are not cleaned in time, they will increase the friction between the tracks and the ground and drive wheels during equipment operation, leading to abnormal track wear. This not only severely shortens the service life of the tracks and increases equipment maintenance costs, but may also cause equipment failure and affect the smooth progress of the project. Utility Model Content
[0004] The purpose of this invention is to provide an excavator undercarriage that facilitates track maintenance. This addresses the issue that in the construction machinery field, equipment such as excavators and bulldozers often operate under complex and harsh conditions, where tracks, as critical walking components, are highly susceptible to accumulating large amounts of sand and soil mixtures. Traditional track cleaning methods mainly include manual cleaning and simple flushing equipment. Manual cleaning is not only labor-intensive and time-consuming, but also inefficient and lacks guaranteed cleaning results. For tightly adhered sand and soil mixtures, thorough removal is difficult. If these mixtures are not cleaned promptly, they will exacerbate friction between the tracks and the ground and drive wheels during equipment operation, leading to abnormal track wear. This not only severely shortens track lifespan and increases equipment maintenance costs but may also cause equipment malfunctions, hindering the smooth progress of projects.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an excavator traveling frame that facilitates track maintenance, comprising a traveling frame, a set of tracks respectively installed on both sides of the traveling frame, a water tank embedded in the surface of one side of the traveling frame, and a water inlet installed on the surface of the water tank;
[0006] The surface of the water tank is also equipped with a water pump pipe. One side of the water pump pipe is connected to the water inlet of the water pump. The two sides of the water pump are connected to a drain pipe. The other end of the drain pipe is connected to a high-pressure nozzle. The water outlet of each high-pressure nozzle is aligned with the outer wall of a set of tracks.
[0007] To prevent the excavator cab from interfering with the water pump when mounted on the traveling frame, as a preferred design for an excavator traveling frame that facilitates track maintenance, the top of the water pump is lower than the highest point of the traveling frame, and the bottom bracket of the high-pressure nozzle is mounted on the surface of the traveling frame.
[0008] In order to filter the water entering the water tank and prevent the entire water supply mechanism from being blocked by large debris in the water, as an excavator walking frame that is easy to maintain the tracks according to this utility model, preferably, the water inlet is located at the bottom of one end of the water tank and a connecting rod is installed thereon, and a disc is fixedly connected to the bottom of the connecting rod.
[0009] Six connecting rods are installed at equal intervals along the outer wall of the bottom opening of the water inlet. Filter cotton is installed between the six connecting rods. The vertical length of the filter cotton is greater than the vertical length of the connecting rods, and the top of the filter cotton is located one-third above the bottom opening of the water inlet.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] When using, open the water inlet and add cleaning water into it. When the water tank is full, start the water pump. The water pump will draw water out of the tank through the water pipe and then deliver it to the drain pipe. Finally, the water will be sprayed onto the track through the high-pressure nozzle.
[0012] When the tracks still contain a large amount of sand and soil mixture, the sand and soil mixture can be effectively cleaned by the high-pressure nozzles as the chassis moves. This reduces the wear and tear on the tracks caused by the sand and soil during movement, thus effectively maintaining the tracks. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-3 The present invention provides the following technical solution: an excavator traveling frame that is easy to maintain tracks, including a traveling frame 1, a set of tracks 2 installed on both sides of the traveling frame 1, a water tank 3 embedded on the surface of one side of the traveling frame 1, and a water inlet 4 installed on the surface of the water tank 3.
[0020] The surface of the water tank 3 is also equipped with a water suction pipe 5. One side of the water suction pipe 5 is connected to the water inlet of the water pump 6. The two sides of the water pump 6 are connected to a drain pipe 7. The other end of the drain pipe 7 is connected to a high-pressure nozzle 8. The water outlet of each high-pressure nozzle 8 is aimed at the outer wall of a set of tracks 2.
[0021] Preferably, the top of the water pump 6 is lower than the height of the highest point of the walking frame 1, and the bottom bracket of the high-pressure nozzle 8 is mounted on the surface of the walking frame 1.
[0022] In actual use, the excavator's cab will not interfere with the water pump 6 when it is mounted on the traveling frame 1;
[0023] Preferably, a connecting rod 41 is installed at the bottom of one end of the water tank 3 for the water inlet 4, and a disc 42 is fixedly connected to the bottom of the connecting rod 41;
[0024] Six connecting rods 41 are installed at equal intervals along the outer wall of the bottom opening of the water inlet 4. Filter cotton 43 is installed between the six connecting rods 41. The vertical length of the filter cotton 43 is greater than the vertical length of the connecting rods 41. The top of the filter cotton 43 is located one-third above the bottom opening of the water inlet 4.
[0025] When in use, the filter cotton 43 needs to be inserted between the six connecting rods 41. When the cleaning water enters the water tank 3 through the water inlet 4, the filter cotton 43 can effectively block foreign objects in the water, making the water entering the water tank 3 cleaner and preventing blockage caused by larger foreign objects in the water supply system.
[0026] In practical use, open the water inlet 4 and inject cleaning water into it. Once the water tank 3 is full, start the water pump 6. It will then pump the water out of the water tank 3 through the suction pipe 5 and deliver it to the drain pipe 7 at a certain water pressure.
[0027] Finally, the water flows through the high-pressure nozzle 8 and impacts the track 2 at high speed. When the track 2 is covered with a large amount of sand and soil mixture, the traveling frame 1 propels the track 2 forward. During this movement, the high-pressure water jet continuously sprayed from the high-pressure nozzle 8 powerfully washes away the sand and soil mixture on the track 2. In this way, the high-pressure nozzle 8 effectively removes the mud and sand mixture from the gaps in the track 2. This not only reduces the wear and tear on the track 2 caused by sand and soil, extending the service life of the track 2, but also reduces the time and cost of equipment maintenance, thus achieving the function of efficiently maintaining the track 2.
[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
