Technical Field
[0001] This utility model belongs to the field of scraper conveyor maintenance technology, specifically an auxiliary tool for inspecting the passability of the scraper after maintenance of the middle trough of a scraper conveyor. Background Technology
[0002] Scraper conveyors are transport machinery used in coal mine working faces. They are mainly used for transporting coal in coal faces and mining area roadways, and can also be used in coal roadways and semi-coal-rock roadway excavation faces. They can transport materials upwards and downwards, generally not exceeding 35 degrees for upward transport and 25 degrees for downward transport, ideally not exceeding 20 degrees in practice. Scraper conveyors have advantages such as transport capacity unaffected by the size and moisture of the load, small machine height for easy loading, convenient machine length adjustment, and a robust body suitable for use in blasting and loading faces. Therefore, they are widely used in many coal mines. However, their disadvantages include: high operating resistance, high power consumption, severe chute wear, easy chain breakage due to improper maintenance and use, and certain limitations on transport distance.
[0003] After prolonged use underground, the central trough of the scraper conveyor requires repair due to wear. During repair, severely worn areas such as the inner recesses of the trough walls, the lower slope of the upper edge of the trough walls, the upper slope of the trough walls, and the bottom plate need to be repaired by welding and overlaying. Because it is difficult to measure the wear thickness and existing dimensions of the central section of the trough walls, there is a possibility of excessive weld overlay in certain areas, preventing the scraper from passing through the repaired central trough and thus affecting the normal operation of the scraper conveyor. Given this problem, the passability of the scraper in the repaired central trough usually needs to be inspected. However, due to the weight of the scraper itself and the difficulty in handling it, directly using the scraper to inspect the passability of the repaired central trough is both difficult to operate and consumes a significant amount of time and manpower.
[0004] Therefore, it is necessary to provide a new auxiliary tooling for inspecting the scraper passability after maintenance of the central trough of a scraper conveyor to solve the above-mentioned technical problems. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it. The technical solution of this utility model will be described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.
[0024] See Figures 1 to 4 This embodiment proposes an auxiliary tooling for inspecting the passability of the scraper after maintenance of the middle trough of a scraper conveyor. It includes a middle trough body 1. Dumbbell pin male heads 2 are fixedly installed on both sides of one end of the middle trough body 1, and dumbbell pin female heads 3 are fixedly installed on both sides of the other end of the middle trough body 1. The dumbbell pin male heads 2 and dumbbell pin female heads 3 are compatible. The middle trough body 1 is provided with a male head positioning tooling 4, a female head positioning tooling 5, and a scraper template 6.
[0025] like Figure 3As shown, the male head positioning fixture 4 includes a male head positioning frame 41, two support blocks 42, two male head claws 43, two mounting plates 44, a track square tube 45, and a pin screw 46. The two support blocks 42 are respectively fixedly installed at the bottom positions of both ends of the male head positioning frame 41. The two male head claws 43 are respectively fixedly installed on the side of the two support blocks 42 that are far apart from each other. The two mounting plates 44 are both fixedly installed at the bottom middle position of the male head positioning frame 41. One end of the track square tube 45 is inserted between the two mounting plates 44. The pin screw 46 is installed on the two mounting plates 44 and passes through the track square tube 45, fixing the track square tube 45 to the mounting plate 44.
[0026] The track square tube 45 can be fixed to the two mounting plates 44 by pin screws 46, and the male head positioning bracket 41 can be locked onto the two dumbbell pin male heads 2 by support block 42 and male head claw 43.
[0027] like Figure 4 As shown, the female head positioning fixture 5 includes a female head positioning frame 51, two square tube positioning plates 52, two strip plates 53, two extension frames 54, two L-shaped plates 55, and two female head claws 56. The two square tube positioning plates 52 are fixedly installed in the middle of one side of the female head positioning frame 51. The two strip plates 53 are respectively fixedly installed at the bottom of both ends of the female head positioning frame 51. The two extension frames 54 are respectively fixedly installed on the top of the two strip plates 53. The two L-shaped plates 55 are respectively fixedly installed at the bottom of the two extension frames 54. The two female head claws 56 are respectively fixedly installed on the side of the two L-shaped plates 55 that are close to each other.
[0028] The female head positioning bracket 51 can be locked onto the two dumbbell pin seat female heads 3 by the L-shaped plate 55 and the female head claw 56, and one end of the track square tube 45 is inserted between the two square tube positioning plates 52 to ensure the centering of the track square tube 45 in the middle groove body 1.
[0029] like Figures 1 to 4 As shown, handles are fixedly installed on the male head positioning frame 41, the female head positioning frame 51, and the scraper template 6;
[0030] By providing handles, it is easy for workers to lift the male head positioning fixture 4, the female head positioning fixture 5, and the scraper template 6 to install and use the auxiliary fixtures.
[0031] like Figure 2 As shown, a rectangular guide groove is provided at the bottom of the scraper template 6. The rectangular guide groove is adapted to the track square tube 45. The bottom surface of the scraper template 6 is in contact with and adapted to the upper surface of the middle groove body 1.
[0032] By setting a rectangular guide groove, it is possible to ensure that the scraper template 6 does not deviate when passing through the central groove body 1 while moving within the central groove body 1.
[0033] The working principle of the auxiliary tooling for inspecting the scraper's passability after repairing the middle trough of the scraper conveyor provided by this utility model is as follows:
[0034] First, the track square tube 45 can be fixed to the two mounting plates 44 by pin screws 46, and the male head positioning bracket 41 can be clamped onto the two dumbbell pin seat male heads 2 by the support block 42 and the male head claw 43. Then, the scraper template 6 can be clamped onto the track square tube 45. After that, the female head positioning bracket 51 can be clamped onto the two dumbbell pin seat female heads 3 by the L-shaped plate 55 and the female head claw 56, and one end of the track square tube 45 can be inserted between the two square tube positioning plates 52. This constitutes an auxiliary tooling for inspecting the scraper passability after maintenance of the middle trough of the scraper conveyor. Finally, the scraper template 6 can be moved in the middle trough body 1 by the handle on the scraper template 6, and the scraper template 6 can be prevented from deflecting by the track square tube 45, thereby inspecting the passability of the middle trough body 1 after maintenance.
[0035] It should be noted that the device structure and accompanying drawings of this utility model mainly describe the principle of this utility model.
