Description

Technical Field

[0001] This utility model relates to the technical field of coal mine scraper repair equipment, and in particular to a curved scraper repair machine. Background Technology

[0002] A curved scraper conveyor is a conveyor that uses a scraper chain to pull and transport bulk materials in a trough. It is commonly used for transporting coal and ore.

[0003] Existing curved scraper conveyors, due to the large amount of ballast material, often develop bent scrapers over long-term use, affecting the normal operation and use of the equipment. Repairing bent scrapers typically involves purchasing new scrapers for replacement or returning them to the factory for repair, both of which are costly and time-consuming.

[0004] In the process of implementing this embodiment, the inventors discovered at least the following problems:

[0005] Existing curved scraper conveyors have high costs and long repair times due to scraper bending. Utility Model Content

[0029] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] This embodiment provides a curved scraper repair machine. Please refer to [link / reference]. Figure 1 As shown, the system includes a support frame 100, a hydraulic cylinder 200, a pick 300, a hydraulic pipe assembly 400, a valve assembly 500, and an oil tank 600. One end of the hydraulic cylinder 200 is fixedly connected to the support frame 100, and its output end is connected to the pick 300. The hydraulic pipe assembly 400 includes a first hydraulic pipe 410, a second hydraulic pipe 420, and a third hydraulic pipe 430. The valve assembly 500 includes a supply valve 510, an inlet valve 520, and a return valve 530. The first hydraulic pipe 410 and the second hydraulic pipe 420 are respectively connected to the hydraulic cylinder 200, the third hydraulic pipe 430 is connected to the first hydraulic pipe 410, and the second hydraulic pipe 420 is connected to the first hydraulic pipe 410. The supply valve 510 is installed on the third hydraulic pipe 430, the inlet valve 520 is installed on the first hydraulic pipe 410, and the return valve 530 is installed on the second hydraulic pipe 420. The first hydraulic pipe 410 and the third hydraulic pipe 430 are respectively connected to the oil tank 600.

[0031] Specifically, the support frame 100 supports the hydraulic cylinder 200, which drives the pick 300 to move up and down. The hydraulic pipe assembly 400 delivers the emulsion from the oil tank 600 into the hydraulic cylinder 200. The valve assembly 500 controls the opening and closing of the hydraulic pipe assembly 400. When the hydraulic cylinder 200 drives the pick 300 downward, the supply valve 510 and the inlet valve 520 open, and the return valve 530 closes. The emulsion enters the first hydraulic pipe 410 from the third hydraulic pipe 430, and then enters the hydraulic cylinder 200. When the hydraulic cylinder 200 drives the pick 300 upward, the inlet valve 520 closes, and the return valve 530 opens. The emulsion enters the second hydraulic pipe 420 from the first hydraulic pipe 410, and then enters the hydraulic cylinder 200. In use, the bent scraper is placed at the bottom of the support frame 100, the supply valve 510 and the inlet valve 520 are opened, and the return valve 530 is closed. The emulsion in the oil tank 600 enters the first hydraulic pipe 410 from the third hydraulic pipe 430, and then enters the hydraulic cylinder 200. The hydraulic cylinder 200 drives the pick 300 to move downward to repair the bent scraper. Then the inlet valve 520 is closed and the return valve 530 is opened. The emulsion in the oil tank 600 enters the second hydraulic pipe 420 from the first hydraulic pipe 410, and then enters the hydraulic cylinder 200 to lift the pick 300, thereby removing the bent scraper from the support frame 100.

[0032] In this embodiment, the support frame 100 includes a base plate 120 and a tripod 110; the bottom of the tripod 110 is welded to the base plate 120, and the hydraulic cylinder 200 is connected to the tripod 110.

[0033] Specifically, the base plate 120 is made of channel steel, and the tripod 110 is also made of two channel steels welded together. Channel steel is a commonly used material and is easy to find; the base plate 120 is used to support the scraper.

[0034] In this embodiment, the tripod 110 is connected to a round pin 130, and the round pin 130 passes through the tripod 110.

[0035] Specifically, the setting of the round pin 130 facilitates the fixing of the hydraulic cylinder 200 to the tripod 110.

[0036] In this embodiment, a reinforcing rib 140 is welded to the top of the tripod 110.

[0037] Specifically, since the tripod 110 is made of two channel steels welded together, the connection strength is relatively weak. The reinforcing rib 140 is used to strengthen the stability of the tripod 110.

[0038] In this embodiment, the pick 300 is provided with a groove 310.

[0039] Specifically, the groove 310 is adapted to the width of the curved scraper to hold the scraper in place, allowing for stable repair.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
