Detailed Description

In order to make the technical solutions and advantages of the present invention more clearly understood, the following description is made in further detail for the exemplary embodiments of the present invention with reference to the accompanying drawings. It is clear that the described embodiments are only a few embodiments of the invention, and are not exhaustive of all embodiments. And the embodiments and features of the embodiments may be combined with each other without conflict.

As shown in fig. 1 to 5, the antiskid device 100 for coal mining machine according to the embodiment of the present invention includes a middle frame 2 and an antiskid assembly. Wherein, as shown in fig. 1 and 2, the antiskid components are hinged at one longitudinal end of the middle frame 2, and when needing antiskid, the antiskid components are transferred to the ground for antiskid, and can be folded when not needing antiskid. Specifically, as shown in fig. 3, the anti-skid assembly 1 includes an adjusting bracket 1, a driving member 16, a rotating rod 9, an anti-skid member 10, and a locking assembly. Wherein, alignment jig 1 is for articulated formula setting on middle frame 2, mainly plays basic effect of supporting. The driving piece 16 is used for driving the adjusting frame 1 to perform lifting movement relative to the middle frame 2 so as to retract the adjusting frame 1 or lower the adjusting piece 1. The rotating rod 9 is connected with the adjusting bracket 1 in a rotating way. The anti-slip element 10 is fixed on the rotary rod 9. The locking assembly serves to restrict the rotation of the rotary lever 9 relative to the adjustment bracket 1.

In the use process, the driving element 16 drives the adjusting bracket 1 to move up, and then the adjusting bracket 1 drives the rotating rod 9 and the anti-skid element 10 to move away from the ground together, so that the anti-skid element 10 is separated from the ground, and at this time, the anti-skid operation is not performed. When the driving member 16 drives the adjusting bracket 1 to move downwards, the adjusting bracket 1 drives the rotating rod 9 and the anti-skid member 10 to approach the ground together, so that the anti-skid member 10 falls on the ground. At this time, if the locking assembly is not operated, the anti-slip member 10 can perform a rotational movement with respect to the adjusting bracket 1 together with the rotating rod 9, has a small resistance anti-slip function, and provides for a later complete anti-slip. At this time, if the locking assembly is operated, the anti-slip member 10 cannot perform a rotation movement with respect to the adjustment bracket 1, thereby providing a complete anti-slip effect. The antiskid device of the coal mining machine can not only realize antiskid operation, but also gradually enter a complete antiskid state in the antiskid operation, and is beneficial to buffering, effectively avoids stress concentration, and is unlikely to damage equipment due to too large antiskid resistance.

In one embodiment, as shown in fig. 3, the anti-slip member 10 includes a disc 101 sleeved on the outer wall of the rotating rod 9, and anti-slip pieces 102 arranged on the outer circumferential surface of the disc 101 at intervals in the circumferential direction. For example, the anti-slip sheet 102 is configured in a substantially rectangular plate shape, four in number, and evenly distributed on the outer circumferential surface of the disc 101. The anti-skid device 10 with the arrangement can conveniently realize the function of buffering, and the anti-skid service life can be prolonged by the plurality of anti-skid plates 102. Preferably, the anti-slip members 10 are two and spaced apart in the axial direction of the rotary rod 9 for improving the uniform anti-slip resistance. For example, the cleats 10 are preferably made of a ferrous material.

In one embodiment, the locking assembly includes stationary teeth 11 and latch teeth 8. The fixed teeth 11 are fixedly sleeved on the outer wall of the rotating rod 9 and are positioned between the two anti-skid members 10. The latch 8 is provided on the adjusting bracket 1 for selective engagement with the fixed teeth 11. In particular, the latch 8 is arranged on the translation plate 7 parallel to the rotation rod 9. At the end of the translating plate 7 facing away from the rotating rod 9, a transverse plate 20 is provided parallel to the translating plate 7. Between the translation plate 7 and the transverse plate 20 there is arranged a reinforcement plate 3 parallel to the rotary rod 9. The reinforcing plate 3 is fixedly connected with the adjusting frame 1. A side bar 6 is fixedly arranged between the translation plate 7 and the transverse plate 20. The side bars 6 are inserted through the reinforcement plate 3 with clearance. The side rods 6 are two and are distributed at intervals in the axial direction of the rotating rod 9 for fixing the translation plate 7 and the transverse plate 20. A screw rod 5 is arranged between the adjusting frame 1 and the transverse plate 20, and the screw rod 5 is in threaded connection with the transverse plate 20. That is, by rotating the screw 5, the transverse plate 20 is driven to move longitudinally, and then the side rods 6 and the translation plate 7 are driven to move longitudinally in turn, so as to drive the latch 8 to approach or depart from the fixed teeth 11, thereby realizing selective engagement of the latch 8 and the fixed teeth 11.

In a preferred embodiment, the adjusting carriage 1 is constructed in the shape of a U-shaped frame with its opening facing the swivel lever 9. A guide rod 12 passing through the transverse plate 20 is fixedly arranged between the adjusting bracket 1 and the reinforcing plate 3. The guide rod 12 ensures that the cross plate 20 moves along the guide of the guide rod 12, thereby ensuring the movement smoothness of the cross plate 20.

As shown in fig. 4, the screw 5 is driven by a first motor 4 provided on the adjustment frame 1. A spline is provided between the drive shaft of the first motor 4 and the screw 5.

As shown in fig. 5, a connecting rod 13 is fixedly provided to the adjusting bracket 1. For example, two engaging lugs 21 are provided on the adjusting bracket 1. Meanwhile, the adjusting bracket 1 is provided with a mounting groove 22. The connecting lug 21 is inserted into the mounting groove 22 and then is in interference fit with the connecting rod 13. The connecting rod 13 is fixedly sleeved with the second gear 14. The first gear 15 is connected in mesh to the second gear 14. A drive configured as a second electric motor 16 drives the first gear 15 in rotation. Thus, under the driving of the second motor 16, the first gear 15 rotates, which in turn drives the second gear 14 to rotate, which in turn drives the connecting rod 13 to rotate, and finally drives the adjusting bracket 1 to rotate. Therefore, the rotation angle of the adjusting bracket 1 can be adjusted through the arrangement, so as to meet the use requirement.

In the present application, as shown in fig. 2, the intermediate frame 2 is further provided with a driving wheel 18, a driven wheel 19, and a traveling frame 17 for performing the movement of the intermediate frame 2.

The first motor and the second motor are both servo motors. The electrical components presented in the document are all electrically connected with an external master controller and 220V mains, and the master controller can be a conventional known device controlled by a computer or the like.
