Description

Technical Field

[0001] The utility model relates to the technical field of scraper machines, in particular to a track structure of a scraper machine. Background Art

[0002] The scraper is a transport machine used in coal mining working faces. It is mainly used for coal mining working faces and mining area chute transportation. It can also be used in coal tunnels and semi-coal rock tunnel excavation working faces. It can transport upwards or downwards. The upward transportation is generally not more than 35 degrees, and the downward transportation is generally not more than 25 degrees. In fact, it is better not to exceed 20 degrees. The scraper is also called a chute, which is widely used in daily mining and transportation work in coal mines.

[0003] The two ends of the scraper steel of the heavy-duty coal slime transfer scraper are connected to the connecting ring by bolts. The tracks of the existing scraper are mostly connected by bolts and other means, which makes it very troublesome to connect the tracks, resulting in the same cumbersome maintenance and disassembly in the later stage. The scraper still has certain limitations during use. Therefore, a track structure of the scraper is proposed to solve the above problems. Utility Model Content

[0007] A limiting piece is arranged at one end of the cross bar located outside the support frame.

[0008] Furthermore, a threaded hole located outside the screw rod is opened inside the driving block, and the threaded hole cooperates with the thread outside the screw rod. The inner side wall of the support frame is fixedly connected to a rectangular rod with one end passing through the driving block.

[0009] Furthermore, a circular hole located outside the cross bar is formed on the inner side wall of the connecting frame, and a rectangular hole located outside the cross bar is formed on the inner side wall of the supporting frame.

[0010] Furthermore, the limiting member comprises a threaded ring with one end threadedly connected to the outer side of the cross bar, a hinge block is fixedly connected to the outer side of the threaded ring, and a limiting rod with one end extending to the inside of the cross bar is rotatably connected to the inner side of the hinge block.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-2 In this embodiment, a track structure of a scraper includes a support frame 1, a track body 2 is provided at the upper end of the support frame 1, a mounting rod 3 is fixedly connected to one side of the track body 2, and a driving member 4 is provided on the inner side of the support frame 1;

[0023] The driving member 4 includes a double-axis motor 41 with one end fixedly connected to the inner bottom wall of the support frame 1, the output shaft of the double-axis motor 41 is fixedly connected to a screw 42 with one end rotatably connected to the inner wall of the support frame 1, the outer side of the screw 42 is threadedly connected to a driving block 43, the lower end of the track body 2 is fixedly connected to a connecting frame 45, the inner side of the connecting frame 45 is slidably connected to a movable block 46, the outer side of the driving block 43 is hinged to an inclined rod 44 with one end hinged to the movable block 46, the inner side wall of the support frame 1 is fixedly connected to a stopper 48, and the movable block 46 is fixedly connected to a cross rod 47 with one end penetrating and extending to the outside of the support frame 1 on the side away from the inclined rod 44.

[0024] In this embodiment, when the threaded ring 491 on the outside of the cross bar 47 fixes the cross bar 47, the laterally moving driving block 43 can lift or lower the connecting frame 45 and the track body 1 through the inclined rod 44 and the movable block 46, and by pressing the limit rod 493 to separate from the cross bar 47 and unscrewing the threaded ring 491, the limit cross bar 47 is no longer fixed. At this time, the laterally moving driving block 43 can drive the movable block 46 and the cross bar 47 to move laterally together through the inclined rod 44 until the cross bar 47 is separated from the rectangular hole 410, and the track body 1 can be disassembled.

[0025] Among them, a threaded hole located on the outside of the screw 42 is opened inside the driving block 43, and the threaded hole cooperates with the thread on the outside of the screw 42. The inner wall of the support frame 1 is fixedly connected to a rectangular rod with one end passing through the driving block 43, so that the rotating screw 42 can drive the driving block 43 to move stably laterally.

[0026] In addition, the inner wall of the connecting frame 45 is provided with a circular hole located outside the cross bar 47, and the inner wall of the supporting frame 1 is provided with a rectangular hole 410 located outside the cross bar 47, so that the cross bar 47 passing through the supporting frame 1 has space to move up and down.

[0027] See also Figure 3-4 In this embodiment, the limiting member 49 includes a threaded ring 491 with one end threadedly connected to the outer side of the cross bar 47, a hinge block 492 is fixedly connected to the outer side of the threaded ring 491, and the inner side of the hinge block 492 is rotatably connected to a limiting rod 493 with one end extending to the inside of the cross bar 47.

[0028] In this embodiment, when the threaded ring 491 is tightened on the cross bar 47 and limited by the limiting rod 493, the threaded ring 491 can block the cross bar 47, making it impossible for the cross bar 47 to be separated from the rectangular hole 410. In any case, the cross bar 47 can be separated from the rectangular hole 410.

[0029] Among them, the outer side of the cross bar 47 located at the outer end of the support frame 1 is provided with an external thread, and the external thread cooperates with the thread inside the thread ring 491 so that the rotating thread ring 491 can be tightened on the cross bar 47.

[0030] In addition, a limiting groove is opened on the outer side of the cross bar 47 and is located outside the limiting rod 493. One end of the limiting rod 493 located inside the limiting groove is inclined, so that the limiting rod 493 extending into the limiting groove can limit the rotation of the threaded ring 491, thereby improving the stability of the threaded ring 491 after tightening.

[0031] Secondly, the hinge block 492 is U-shaped, and the inner side of the hinge block 492 is rotatably connected to the limit rod 493 through a rotating shaft. A torsion spring is arranged between the limit rod 493 and the inner side of the hinge block 492, so that the limit block 493 can rotate inside the hinge block 492 and be reset by the torsion spring.

[0032] It should be noted that the outer diameter of the threaded ring 491 is larger than the specification of the rectangular hole 410 .

[0033] The working principle of the above embodiment is:

[0034] Since the started dual-axis motor 41 can drive the driving block 43 to move stably laterally through the screw 42, when the threaded ring 491 on the outside of the cross bar 47 fixes the cross bar 47, the laterally moving driving block 43 can lift or lower the connecting frame 45 and the track body 1 through the inclined rod 44 and the movable block 46, and by pressing the limit rod 493 to separate from the cross bar 47 and unscrewing the threaded ring 491, the limit cross bar 47 is no longer fixed. At this time, the laterally moving driving block 43 can drive the movable block 46 and the cross bar 47 to move laterally together through the inclined rod 44 until the cross bar 47 is separated from the rectangular hole 410, and the track body 1 can be disassembled to improve the convenience of lifting, adjusting, maintaining and disassembling the track body 1.
