Description

Technical Field

[0001] The utility model belongs to the technical field of excavators, and particularly relates to a track idler mud scraping device, a track idler, a crawler frame and a crawler crane. Background Art

[0002] Since the excavator often works in an environment with a lot of soil on the ground, the crawler often carries a large amount of soil. When the crawler rotates, this soil is likely to spill around the track idler. After a long time, the track idler will be wrapped by a large amount of soil. When the soil dries and hardens, the track idler will have difficulty rotating or even stop rotating completely, which will cause abnormal wear and damage of the track idler. In many existing applications, the track idler needs to be manually cleaned regularly, or a mud dropping hole is opened on the frame below it to reduce soil accumulation. However, manual cleaning is time-consuming and laborious, and due to the structural strength, the opening on the frame below the track idler is generally not large, and the fallen soil is limited, so the problem of soil accumulation still cannot be solved.

[0003] Therefore, it is necessary to design a cleaning device that can not only solve the problem of soil accumulation on the track idler but also is easy to operate. Summary of the Invention

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a track idler mud scraping device, a track idler, a crawler frame and a crawler crane. By setting a track idler bracket on the crawler frame that can accommodate the rotation of the track idler, the soil accumulated on the track idler can be cleaned by a simple means, and there is enough space to store the accumulated soil, ensuring the normal operation and use of the excavator crawler and track idler.

[0005] To achieve the above purpose, the utility model is implemented by the following technical solutions.

[0006] In the first aspect, the utility model provides a track idler mud scraping device, including: a track idler bracket installed on the crawler frame;

[0007] There is a storage space for soil between the track idler bracket and the crawler frame. A slot is opened on the supporting end face of the track idler bracket, and the shape of the slot is adapted to accommodate the rotation of the track idler therein.

[0008] By setting a track idler bracket that forms a storage space with the crawler frame and opening a slot on the track idler bracket for the track idler to rotate therein, the soil wrapped around the outside of the track idler can be scraped and cleaned through the slot, and the storage space between the track idler bracket and the crawler frame can also be used to temporarily store the cleaned soil, simultaneously solving the problems of soil cleaning on the track idler and soil accumulation on the frame below the track idler by a simple means.

[0009] Optionally, mounting holes are provided at both ends of the bearing end face of the carrier wheel support;

[0010] The mounting holes are respectively located on both sides of the bearings at both ends of the carrier wheel and are used to clamp and fix the carrier wheel bearings in combination with fixing rods.

[0011] By providing mounting holes on the upper end face of the carrier wheel support to fix the bearings at both ends of the carrier wheel shaft, there is no need to fix the scraper, carrier wheel and crawler frame with several bolts on the same plane like existing scraper equipment, which not only simplifies the structure of the scraping equipment, but also reduces the risk of loosening between the scraper, carrier wheel and crawler frame, and has higher reliability.

[0012] Optionally, the contour shape of the slot is matched with the outer contour shape of the cross-section of the carrier wheel and is slightly larger than the outer contour shape of the cross-section of the carrier wheel.

[0013] Optionally, the contour shapes of both sides of the slot parallel to the carrier wheel shaft are formed into teeth.

[0014] By setting the contour of the slot to be tooth-shaped, the effect of easier and more and faster scraping compared with the existing scraper can be achieved through a simple setting.

[0015] Optionally, the carrier wheel support is in an inverted U-shaped structure, and its upper end face is used to support and accommodate the rotation of the carrier wheel.

[0016] In a second aspect, the present invention provides a carrier wheel, and the carrier wheel is detachably mounted on the carrier wheel scraping device according to any step of the first aspect.

[0017] In a third aspect, the present invention provides a crawler frame, including the carrier wheel according to the second aspect.

[0018] In a fourth aspect, the present invention provides a crawler crane, including the crawler frame according to the third aspect and a crawler surrounding the crawler frame and the carrier wheel provided thereon.

[0019] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows: In this application, a carrier wheel support is provided on the crawler frame, and a receiving space is formed between the carrier wheel support and the crawler frame. A slot is opened on the carrier wheel support for the carrier wheel to rotate therein. Through this slot, the soil wrapped around the outside of the carrier wheel can be scraped and cleaned. Moreover, the receiving space between the carrier wheel support and the crawler frame can also store the cleaned soil. Compared with the limited leaky soil holes in the prior art, it can accommodate more cleaned soil, and simultaneously solves the problems of soil cleaning on the carrier wheel and soil accumulation on the frame below the carrier wheel by a simple means; In this application, by providing an inverted U-shaped carrier wheel support, its two vertical walls are installed on the crawler frame, and the carrier wheel is installed on its upper end surface in a manner that does not affect its rotation, which simplifies the structure and improves the stability compared with the prior art; This application also designs the contour of the toothed slot. The toothed plate is more labor-saving and easier when scraping mud than the linear plate, and can achieve a better and faster mud scraping effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] This embodiment provides a sprocket mud scraping device, including: a sprocket support 3 installed on a crawler frame 4;

[0028] There is an accommodation space for storing mud between the sprocket support 3 and the crawler frame 4. A slot hole 3-4 is formed on the supporting end surface of the sprocket support 3, and the shape of the slot hole 3-4 is adapted to accommodate the rotation of the sprocket 1 therein. Embodiment 2

[0029] Based on Embodiment 1, the following design is further made in this embodiment.

[0030] The sprocket support 3 is in an inverted U shape. The two vertical walls on both sides of the inverted U-shaped sprocket support 3 are fixed to the crawler frame 4, and a square slot hole 3-4 is formed on its upper end surface. The shape and size of the square slot hole 3-4 are adapted to the cross-sectional shape and size of the sprocket 1, and there is a certain gap between the square slot hole 3-4 and the outer surface of the sprocket 1, so that the sprocket 1 wrapped with mud can rotate therein.

[0031] In this embodiment, a receiving space is formed between the upper end surface of the inverted U-shaped idler sprocket bracket 3 and the two vertical walls on both sides thereof and the crawler frame 4. This receiving space can store the soil scraped off through the square slot holes of the idler sprocket bracket 3, without the need to open special mud-drop holes on the bottom plate of the box of the crawler frame 4 as in the traditional mud scraper, which simplifies the structure of the mud scraping equipment and solves the problem of soil accumulation caused by the limited size of the mud-drop holes set in consideration of the structural strength of the crawler frame 4 in the prior art.

[0032] In this embodiment, mounting holes 3-3 are also provided on the upper end surface of the inverted U-shaped idler sprocket bracket 3. The mounting holes 3-3 are respectively provided on both sides of the bearings at both ends of the axle of the idler sprocket 1, that is, four mounting holes 3-3 with symmetric positions are provided; the bearings at both ends of the idler sprocket 1 are fixed by setting fixing rods in the mounting holes 3-3, and the idler sprocket 1 is mounted on the idler sprocket bracket 3 in a way that does not affect the rotation of the idler sprocket 1. Moreover, the idler sprocket bracket 3 and the crawler frame 4 as well as the idler sprocket 1 and the idler sprocket bracket 3 are respectively fixed on different planes. Compared with the prior art in which the mud scraper, the idler sprocket 1 and the crawler frame 4 are fixed by several bolts on the same plane, not only the structure is further simplified, but also the risk of loosening between the idler sprocket 1, the idler sprocket bracket 3 and the crawler frame 4 caused by friction during the rotation of the idler sprocket 1 and the crawler is greatly reduced, making the structure more stable.

[0033] In this embodiment, the long side contours on both sides of the square slot hole 3-4 are set to be tooth-shaped and match the outer contour of the cross-section of the idler sprocket 1, that is, the long side contour of each side of the square slot hole 3-4 is formed into a tooth-shaped structure combined with shorter side teeth 3-2 and longer middle teeth 3-1, which is convenient for better scraping and cleaning the soil wrapped on the idler sprocket 1 according to the shape of the idler sprocket 1, and a faster and better mud scraping effect is achieved with the tooth-shaped structure. The tooth-shaped structure in this embodiment can be replaced with different shapes or in different positions, and can be either on the same horizontal plane as the cross-section of the idler sprocket or in an up-turned or down-dropped state, as long as it adapts to the outer surface contour of the idler sprocket 1. Embodiment 3

[0034] This embodiment provides an idler sprocket 1, which is mounted in the idler sprocket mud scraping equipment as described in Embodiment 2, and the size of its outer surface is adapted to rotate in the square slot hole 3-4 provided on the idler sprocket bracket 3. Embodiment 4

[0035] This embodiment provides a crawler frame 4, which includes the idler sprocket 1 as described in Embodiment 3. The idler sprocket bracket 3 equipped with the idler sprocket 1 is arranged on the crawler frame 4, and a receiving space for storing the scraped-off soil is formed between the idler sprocket bracket 3 and the crawler frame 4. Embodiment 5

[0036] This embodiment provides a crawler crane, which includes a crawler frame 4 as described in Embodiment 4 and a crawler that is disposed around the crawler frame 4 and the idler sprockets 1 provided thereon.

[0037] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
