Description

Technical Field

[0001] The utility model relates to the technical field of subway track construction equipment, and particularly relates to a device for clearing the bottom of a subway tunnel excavation. Background Art

[0002] During the modification of subway tracks, a large amount of work such as tunnel excavation and platform construction is required. During these construction processes, a large amount of solid waste will be generated. Therefore, as an important part of safe and civilized construction, site cleaning needs to be carried out daily, which virtually increases the workload. Moreover, after the concrete blocks spilled during the in-site construction solidify, it is difficult for workers to clean them up.

[0003] For solid waste with a large volume or a large quantity, a loader is often used for preliminary cleaning. During cleaning, the solid waste is dug up or shoveled up by the bucket of the loader and transported to the destination, which can greatly improve the work efficiency.

[0004] However, since the bucket design of a common loader is mainly used for shoveling large pieces of materials, there are relatively large gaps between the steel teeth in front of the bucket. The cleaning effect on fine or scattered materials is often not ideal. When used for ground cleaning, a large part of the garbage and solid waste will pass through the gaps. Therefore, using a common loader to clean the site will result in incomplete cleaning of the construction site, and manual secondary cleaning is required, which increases the workload and time cost. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the technical problem to be solved by the utility model is to provide a device for clearing the bottom of a subway tunnel excavation, which is used for quickly and effectively cleaning construction access roads, construction sites and other sites. Thereby reducing the time and labor intensity of manual cleaning, and at the same time ensuring the safety of operators.

[0006] To achieve the above purpose, the utility model is realized by the following technical solutions: A device for clearing the bottom of a subway tunnel excavation is installed on the bucket of a loader, and includes:

[0007] A baffle plate, the baffle plate is strip-shaped, the baffle plate is arranged along the width direction of the bucket, covers the bucket teeth of the bucket, and blocks all the gaps between the bucket teeth of the bucket; and

[0008] A connecting piece, the baffle plate is detachably connected to the bucket through the connecting piece.

[0009] Further, the connecting piece includes a connecting plate, the connecting plate is connected to the side of the baffle plate close to the bucket teeth, a plurality of jacks are arranged at intervals along the length direction of the connecting plate, the plurality of jacks are arranged in one-to-one correspondence with the plurality of bucket teeth, and the bucket teeth can be inserted into the jacks and are in tight fit with the jacks.

[0010] Further, a limiting member is further included. The limiting member includes a limiting rod. A limiting hole is formed along the bucket tooth, and the limiting hole is located on the side close to the end of the bucket tooth relative to the connecting plate. The limiting rod can be detachably inserted into the limiting hole, and both ends of the limiting rod extend out of the limiting hole.

[0011] Further, the limiting member further includes a stop rod. The stop rod is arranged on the limiting rod along the radial direction of the limiting rod and extends along the radial direction of the limiting rod.

[0012] Further, the limiting hole extends along the width direction of the bucket and penetrates through the bucket tooth.

[0013] Further, one limiting member is arranged on each bucket tooth.

[0014] Further, a scraper is further included. The scraper is oppositely arranged at both ends of the connecting plate relative to the baffle.

[0028] The embodiments of the technical solutions of the present invention will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention, so they are only examples and cannot be used to limit the protection scope of the present invention.

[0029] Please refer to Figures 1 to 6 , the present invention provides a subway tunnel excavation and bottom-cleaning device, which is installed on the bucket 1 of a loader. It includes a baffle 100 and a connecting member 200. The baffle 100 is long and is arranged along the width direction of the bucket 1, covers the bucket teeth 2 of the bucket 1, and blocks all the gaps between the bucket teeth 2 of the bucket 1. The baffle 100 and the bucket 1 can be detachably connected through the connecting member 200.

[0030] In the normal state, the loader can be used normally. When large pieces of materials need to be cleaned at the work site, the baffle 100 is installed on the bucket 1 through the connecting member 200, so that the baffle 100 covers the bucket teeth 2 of the bucket 1. The baffle 100 blocks all the gaps between the bucket teeth 2. During the operation of the bucket 1, the baffle 100 can prevent small or scattered materials from falling through the gaps between two adjacent bucket teeth 2, thereby improving the cleaning effect, avoiding secondary manual cleaning, reducing the time and labor intensity of manual cleaning, and ensuring the safety of operators.

[0031] In this embodiment, the connecting member 200 includes a connecting plate 210. The connecting plate 210 is connected to the side of the baffle 100 close to the bucket tooth 2. A plurality of jacks 211 are arranged on the connecting plate 210 at intervals along its length direction. The plurality of jacks 211 are arranged in one-to-one correspondence with the plurality of bucket teeth 2, and the bucket teeth 2 can be inserted into the jacks 211 and are in a tight fit with the jacks 211.

[0032] When in use, the connecting plate 210 is installed on the bucket tooth 2 through the jack 211, and the installation of the baffle 100 can be completed quickly. The tightness of the tight fit between the bucket tooth 2 and the jack 211 should be such that it can ensure that the baffle 100 does not fall off during the operation of the bucket 1, and can be removed by external force after cleaning.

[0033] To ensure the installation reliability of the connecting plate 210, the device further includes a limiting member 220. Specifically, the limiting member 220 includes a limiting rod 221. A limiting hole is formed along the bucket tooth 2, and the limiting hole is located on the side close to the end of the bucket tooth 2 relative to the connecting plate 210. The limiting rod 221 can be detachably inserted into the limiting hole, and both ends of the limiting rod 221 extend out of the limiting hole. When installing the connecting plate 210 on the bucket tooth 2, the limiting rod 221 is inserted into the limiting hole. When it is necessary to disassemble the connecting plate 210, the limiting rod 221 needs to be removed first.

[0034] As a preferred embodiment, the limiting member 220 further includes a stop rod 222. The stop rod 222 is arranged on the stop rod 221 along the radial direction of the limiting rod 221 and extends along the radial direction of the stop rod 221. It can play a certain limiting role to prevent the stop rod 222 from falling out of the jack 211.

[0035] In specific implementation, the limiting hole should extend along the width direction of the bucket 1 and penetrate the bucket tooth 2. This facilitates the installation of the limiting rod 221.

[0036] In addition, in specific implementation, a limiting member 220 can be provided on each bucket tooth 2. During the operation, the limiting member 220 can play a certain limiting role on the connecting plate 210, thereby improving the strength and stability of the entire connecting plate 210.

[0037] As another preferred embodiment, the device further includes a scraper 300. The scraper 300 is arranged at both ends of the connecting plate 210 opposite to the baffle 100. The scraper 300 not only has the function of the baffle 100. In addition, when the bucket 1 moves along the ground, the scraper 300 can play a role in scraping the ground, thus solving the problem that the bucket teeth 2 of the loader do not touch the ground and cannot clean fine or scattered materials.

[0038] The usage method of the above subway tunnel excavation and bottom cleaning device:

[0039] In the normal state, the loader can be used normally. When it is necessary to clean large pieces of materials on site, the bucket teeth 2 are used to install the connecting piece 200 and the baffle 100 on the bucket 1 through the jacks 211. At this time, the baffle 100 and the scraper 300 cover the upper and lower sides of the bucket teeth 2 of the bucket 1. The baffle 100 and the scraper 300 block all the gaps between the bucket teeth 2. During the operation of the bucket 1, the baffle 100 can prevent small or scattered materials from falling through the gaps between the bucket teeth 2, and the scraper 300 can play a role in scraping the ground, thus solving the problem that the bucket teeth 2 of the loader do not touch the ground and cannot clean small or scattered materials.

[0040] By adopting the above device, the cleaning effect can be effectively improved, and manual secondary cleaning can be avoided. Furthermore, the time and labor intensity of manual cleaning can be reduced, and the safety of operators can be guaranteed.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
