Description

Technical Field

[0001] The utility model relates to the technical field of scraping devices, in particular to a track equipment scraper. Background Art

[0002] Rail-mounted equipment is crucial for mine development, transportation, and production. It's typically heavy and bulky, requiring the use of winches, locomotives, or manual maneuvering. Equipment such as underground locomotives, ore buckets, rock loaders, air compressors, drilling rigs, and cable racks all require rail transport. However, rail-mounted equipment is difficult to install and transport in areas without rail access, where rail installation is inconvenient, or in sectioned tunnels. Furthermore, rail-mounted equipment requires rail installation and removal for transport, which is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0003] Based on this, the purpose of this utility model is to provide a rail equipment scraper to overcome the problem of difficulty in transporting rail equipment during existing underground operations, realize the transportation of equipment on the working surface without tracks, and is easy to operate, saving a lot of manpower and material resources and shortening the operation time.

[0004] A rail equipment scraper includes a locomotive, a flat bucket connected to the locomotive, and an electric winch arranged on the locomotive for towing the rail equipment. The flat bucket is provided with a rail axle matching the rail equipment. The locomotive controls the lifting and rotation of the flat bucket and drives the flat bucket to move.

[0005] The utility model discloses a rail equipment scraper that uses a flat flat bucket provided with a rail shaft that matches the rail equipment to load and transport the rail equipment. When in use, the flat bucket is first driven by a locomotive to move in front of the rail equipment and the horizontal position and angle of the flat bucket are adjusted. The rail shaft on the flat bucket is aligned with the wheel rail of the rail equipment. An electric winch is used to pull the rail equipment along the rail shaft to the flat bucket. The horizontal position and angle of the flat bucket are then adjusted to a suitable state for transportation. The rail shaft not only facilitates the loading and unloading of the rail equipment, but also prevents the rail equipment from moving left and right during transportation, resulting in uneven loading and tipping of the scraper. The rail equipment shovel loader described in the utility model is cleverly designed and easy to operate, so that large equipment can be transported directly to remote work surfaces without the need to install rails, and the equipment can be directly put into production and use without having to disassemble, transport and install. It has now been used in the underground rail equipment transportation of Fankou Lead-Zinc Mine, saving a lot of manpower in transportation, shortening operation time, greatly improving operation efficiency, and at the same time reducing safety risks and operation costs, achieving good results.

[0006] Furthermore, the locomotive includes a first arm, a second arm, and a lifting cylinder; the first arm and the second arm are parallel to each other and correspondingly arranged on both sides of the flat bucket, and the first arm and the second arm move synchronously. The first arm and the second arm are hinged to the flat bucket via a first pin that passes through the flat bucket; the lifting cylinder includes a pull rod, which is hinged to the flat bucket via a second pin. The rail equipment scraper described in the utility model controls the flat bucket through the first and second arms of the locomotive, and adjusts the angle of the flat bucket by pushing the flat bucket to rotate around the first pin by extending and retracting the pull rod of the lifting cylinder, thereby adjusting the flat bucket to a state suitable for loading and unloading rail equipment.

[0007] Furthermore, the flat bucket includes a bracket and several bottom plates; the bracket includes a first side plate and a second side plate that are parallel to and corresponding to each other, the parts of the first side plate and the second side plate close to the locomotive are the head, and the parts away from the locomotive are the tail; the first side plate and the second side plate are fixedly connected by several main shafts perpendicular to the first side plate and the second side plate; the main shaft is provided with several secondary shafts perpendicular to the main shaft, and the secondary shafts are parallel to the extension directions of the head and the tail of the first side plate and the second side plate, and the secondary shafts include the rail shaft; the bottom plate covers and is fixed to the upper surface of the main shaft, and the rail shaft protrudes from the bottom plate.

[0008] Furthermore, a baffle is provided between the head portions of the first side panel and the second side panel, and is vertically and fixedly connected to the first side panel and the second side panel. The baffle, the first side panel and the second side panel form a semi-enclosed structure.

[0009] Furthermore, the first and second side panels are connected at their respective ends by a hollow sleeve and a second pin; the first pin passes through the hollow sleeve and is fixedly connected to the first and second arms. The hollow sleeve and first pin structure not only achieves an articulated connection between the first and second arms of the locomotive and the flat bucket, but also prevents wear between the first pin and the flat bucket, thereby protecting the flat bucket.

[0010] Furthermore, the flat bucket further includes a plurality of intermediate plates disposed between the nose portions of the first and second side plates, each of which is fixedly connected to the bracket and the bottom plate. A sleeve is provided on the intermediate plate perpendicular to the first and second side plates, with the central axes of the sleeve located on the same horizontal line. A second pin extends through the sleeve and is hingedly connected to the first and second side plates. The pull rod of the lifting cylinder is fixedly connected to the second pin. The sleeve and second pin structure not only achieves the articulated connection between the locomotive's lifting cylinder and the flat bucket, but also prevents wear between the first pin and the intermediate plate, the pull rod, and the second pin, thereby protecting the intermediate plate and the pull rod.

[0011] Furthermore, the middle plates are connected by a connector that distributes the tensile load of the pull rod to all the middle plates and even the brackets, thereby preventing the flat bucket structure from being deformed or even broken due to excessive local tensile load.

[0012] Furthermore, the number of the rail axles is 2; the rail axles include a first rail axle close to the first side plate and a second rail axle close to the second side plate; the middle plate includes a first middle plate, a second middle plate and a third middle plate arranged correspondingly and arranged between the first middle plate and the second middle plate for improving the structural strength of the flat bucket; the first middle plate and the second middle plate are fixedly connected to the first rail axle and the second rail axle respectively, the first middle plate is fixedly connected to the first side plate through a first round steel piece perpendicular to the first middle plate, and the second middle plate and the third middle plate are fixedly connected to the second side plate through a second round steel piece perpendicular to the second middle plate; the first middle plate, the second middle plate and the third middle plate are all fixedly connected to the bottom plate and the main shaft closest to the locomotive. In actual production and operation, in order to facilitate the transportation of the rail equipment scraper, the locomotive and the flat bucket are generally aligned to reduce the footprint of the scraper. However, the lifting cylinder and its pull rod of the existing locomotive are not located on the symmetry axis of the locomotive, so that when the locomotive and the flat bucket are connected, the pull rod of the lifting cylinder cannot be fixedly connected to the midpoint of the second pin shaft, which easily leads to uneven load distribution on the second pin shaft. Providing a third middle plate between the first middle plate and the second middle plate can, on the one hand, strengthen the structural strength of the second pin shaft, and on the other hand, facilitate the dispersion of the tensile load to avoid excessive local tensile load.

[0013] Furthermore, the scraper also includes a tensioner for securing the rail-mounted equipment; the flat bucket is provided with a plurality of fixing holes; the tensioner's rope is passed through the fixing holes to secure the rail-mounted equipment to the flat bucket. The rail-mounted equipment scraper of the present invention uses a tensioner to secure the rail-mounted equipment, thereby preventing the rail-mounted equipment from moving or shaking during transportation, which could cause the rail-mounted equipment to fall, affect transportation stability, and easily cause safety accidents.
