Description

Technical Field

[0001] This application relates to the field of tunnel engineering equipment technology, and in particular to a sliding mechanism for a tunneling arm and a tunneling trolley. Background Technology

[0002] During tunnel construction, the tunnel boring machine's boom relies on a sliding mechanism to achieve multi-directional sliding operations on the large integrated unit. The sliding mechanism typically consists of guide rails, sliding seats, and crossbeams to support the boom's sliding movements in all directions, ensuring its flexible position adjustment to meet different construction needs. The guide rails and sliding blocks work together, powered by a hydraulic or electric system to achieve the boom's sliding motion. In practical applications, this structure reduces friction and ensures smooth movement through the smooth surface of the guide rails and the sliding between the blocks. The sliding mechanism effectively helps the boom maintain flexibility in complex construction environments, and it is particularly important when tunnel construction requires multi-angle operations.

[0003] However, existing tunneling arm sliding mechanisms have some drawbacks. The main problem is that during construction, the sliding mechanism is exposed, and the tunneling machine operates in a complex environment. Sand, dust, and other debris easily fall and accumulate on the guide rails and crossbeams of the sliding mechanism. This accumulation increases sliding resistance, affecting the sliding effect of the tunneling arm and causing slow sliding or even jamming. Over time, this accumulation can also cause wear on the slider and guide rails, increasing equipment failure rates and maintenance costs. The lack of a dedicated sliding protection structure is the primary cause of these problems. Most existing sliding mechanisms lack effective protective devices to isolate or remove debris from the sliding path, thus failing to prevent the impact of sand and dust on sliding performance. As a result, the sliding mechanism requires frequent manual cleaning after prolonged operation, which is labor-intensive and affects construction efficiency and progress. Furthermore, long-term accumulation of debris can also damage and deform the sliding structure, shortening the equipment's lifespan and increasing maintenance and replacement costs. Utility Model Content

[0005] To achieve the above objectives, this application provides a sliding mechanism for a tunneling arm, including a crossbeam, a sliding guide rail, a first sliding seat, and a first scraper; the sliding guide rail is disposed on the crossbeam and arranged along the length of the crossbeam; the first sliding seat is slidably connected to the crossbeam via the sliding guide rail; the first scraper is disposed on the side of the first sliding seat that contacts the sliding guide rail, and the first scraper is used to scrape away debris on the sliding guide rail.

[0006] Optionally, each side of the crossbeam is provided with a sliding guide rail, and the first sliding seat is slidably sleeved on the crossbeam. Multiple first scrapers are provided on both sides of the first sliding seat that contact the sliding guide rail, and multiple first scrapers that cooperate with the corresponding sliding guide rail are provided on the same side of the first sliding seat.

[0007] Optionally, the first scraper can be detachably connected to the first sliding seat.

[0008] Optionally, it also includes two second sliding seats and a second scraper. The two second sliding seats are respectively connected to both ends of the crossbeam, and the sliding direction of the second sliding seats is perpendicular to the sliding direction of the first sliding seat. The second scraper is disposed on the target side of the second sliding seat and is used to scrape off debris on the slide rail that is slidably engaged with the second sliding seat. The target side is the side of the second sliding seat that is in the same sliding direction as the second sliding seat.

[0009] Optionally, two second scrapers are provided on each of the two target sides of the second sliding seat, and the two second scrapers located on the same target side are respectively close to the top and bottom of the second sliding seat.

[0026] Example 1

[0027] Reference Figure 1 This embodiment provides a sliding mechanism for a tunneling arm, including a crossbeam 110, a sliding guide rail 120, a first sliding seat 130, and a first scraper 140. The first sliding seat 130 is used to connect the tunneling arm. The sliding guide rail 120 is disposed on the crossbeam 110 and arranged along the length direction of the crossbeam 110. The first sliding seat 130 is slidably connected to the crossbeam 110 through the sliding guide rail 120. The first scraper 140 is disposed on the side of the first sliding seat 130 that contacts the sliding guide rail 120, and the first scraper 140 is used to scrape away debris on the sliding guide rail 120.

[0028] In this embodiment, when the first sliding seat 130 slides laterally along the crossbeam 110 via the sliding guide rail 120, the first scraper 140 on the side of the first sliding seat 130 can move accordingly, thereby scraping away debris on the sliding guide rail 120, achieving an automatic cleaning function without the need for manual cleaning, ensuring construction efficiency, reducing the risk of damage to the sliding structure, and demonstrating high practicality. Therefore, when this embodiment is applied to a tunneling trolley, it can save debris cleaning time, ensure continuous and uninterrupted operation of the tunneling trolley, and thus improve excavation construction efficiency.

[0029] As an optional implementation, each side of the crossbeam 110 is provided with a sliding guide rail 120, and the first sliding seat 130 is slidably sleeved on the crossbeam 110. Multiple first scrapers 140 are provided on both sides of the first sliding seat 130 that contact the sliding guide rail 120, and multiple first scrapers 140 that cooperate with the corresponding sliding guide rail 120 are provided on the same side of the first sliding seat 130.

[0030] In this embodiment, the crossbeam 110 is generally a rectangular beam, and sliding guide rails 120 can be provided on all four sides of the rectangular beam to facilitate the sliding of the first sliding seat 130 onto the crossbeam 110. The first sliding seat 130 will not fall off, and the sliding structure is reliable and stable. However, due to the increase of sliding guide rails 120, the risk of the sliding guide rails 120 being stuck by debris will also increase. Therefore, multiple first scrapers 140 are provided on both sides of the first sliding seat 130 that contact the sliding guide rails 120, and each sliding guide rail 120 is provided with a corresponding first scraper 140. This ensures that no matter which direction the first sliding seat 130 slides, the debris on the corresponding sliding guide rail 120 can be scraped off by the corresponding first scraper 140, so as to ensure the smooth sliding of the first sliding seat 130.

[0031] It should be noted that in some special structures, the crossbeam 110 may also be a circular beam or a beam of other shapes, and the sliding guide rails 120 may be distributed according to the specific structure of the crossbeam 110.

[0032] As an optional implementation, the first scraper 140 is detachably connected to the first sliding seat 130. When the first scraper 140 has been used for a long time, it will experience a certain degree of wear, thus facilitating its disassembly and replacement to ensure effective debris removal. It should be noted that the first scraper 140 can be detachably connected to the first sliding seat 130 using screws, or other detachable structures, such as snap-fit ​​connections, can also be used.

[0033] As an optional implementation, it also includes two second sliding seats 150 and a second scraper 160. The two second sliding seats 150 are respectively connected to both ends of the crossbeam 110. The sliding direction of the second sliding seats 150 is perpendicular to the sliding direction of the first sliding seat 130. The second scraper 160 is disposed on the target side of the second sliding seat 150. The second scraper 160 is used to scrape away debris on the slide rail that is slidably engaged with the second sliding seat 150. The target side is the side of the second sliding seat 150 that is in the same sliding direction as the second sliding seat 150.

[0034] In this embodiment, since the tunneling arm needs to slide laterally in addition to sliding laterally through the first sliding seat 130, two slidable second sliding seats 150 are provided to drive the crossbeam 110 and the first sliding seat 130 to slide laterally as a whole. Similarly, the second sliding seats 150 are slidably connected to the tunnel construction unit (not shown in the figure) through corresponding slide rails. Therefore, a second scraper 160 is also provided on the side of the second sliding seat 150 that contacts the slide rail (i.e., the target side). When the second sliding seat 150 slides, the second scraper 160 scrapes away the debris on the corresponding slide rail to ensure smooth sliding.

[0035] As an optional implementation, two second scrapers 160 are provided on both target sides of the second sliding seat 150, and the two second scrapers 160 located on the same target side are close to the top and bottom of the second sliding seat 150, respectively.

[0036] In this embodiment, to ensure sliding stability, the top and bottom of the second sliding seat 150 are slidably connected by slide rails, and the second sliding seat 150 needs to move back and forth. Therefore, two second scrapers 160 are provided on the two target sides corresponding to the back and forth movement of the second sliding seat 150, and are respectively arranged on the top and bottom of the second sliding seat 150. This ensures that debris can be removed from the upper and lower slide rails at the same time during the back and forth movement, so as to ensure the cleaning effect.

[0037] As an optional implementation, the second scraper 160 is detachably connected to the second sliding seat 150. Similarly, the second scraper 160 can be replaced after wear, and its detachable structure can adopt a screw, snap-on or other structure.

[0038] As an optional implementation, both second sliding seats 150 are connected to telescopic mechanisms 170. The telescopic mechanisms 170 are used to drive the second sliding seats 150 to perform linear sliding motion. The two second sliding seats 150 can be controlled by their respective telescopic mechanisms 170, which facilitates operation.

[0039] As an optional implementation, the telescopic mechanism 170 includes any one of a telescopic hydraulic cylinder, a telescopic pneumatic cylinder, or an electric push rod, and has the function of automatic telescopic movement to drive the two second sliding seats 150 to move synchronously and automatically.
