Furthermore, the terms "first," "second," and the like, herein used in order to distinguish one element from another element, without sequence or importance.

As shown in fig. 1, one embodiment of the present disclosure provides a dismounting device for a driving wheel of a rolling machine, including a bracket 1, a lifting mechanism 2, and a clamping portion 3. The support 1 can be supported at the top end of the roller bed rail so as to support the whole dismounting device, the contact surface of the support 1 and the top end of the roller bed rail is a supporting point of the whole dismounting device, and the dismounting device can be stably positioned on the roller bed rail through the supporting point of the support 1 and the top end of the roller bed rail. The lifting mechanism 2 is arranged on the support 1, can vertically move relative to the support 1 along the direction that the driving wheel breaks away from the roller bed track, the clamping part 3 is arranged on the lifting mechanism 2, the clamping part 3 can be driven by the lifting mechanism 2 to approach or separate from the driving wheel after the support 1 is supported on the roller bed track, when the driving wheel needs to be disassembled, the clamping part 3 is driven by the lifting mechanism 2 to approach the driving wheel, the clamping part 3 is clamped on two sides of the driving wheel and fixed with the driving wheel, at the moment, the driving wheel can be gradually separated from the roller bed track by the lifting mechanism 2 in a lifting way, and the driving wheel is driven by the clamping part 3, so that the disassembling operation of the driving wheel is realized.

In the above embodiment, the bracket 1 can be stably positioned on the track of the rolling machine to provide support for the dismounting device, and meanwhile, after the clamping part 3 is matched with the driving wheel in a clamping way, the lifting mechanism 2 can drive the driving wheel to move along the direction away from the driving wheel so as to separate the driving wheel from the track of the rolling machine, so that the dismounting process is convenient and labor-saving, the overhaul operation efficiency of the driving wheel of the rolling machine is improved, and the driving wheel is prevented from being subjected to overlarge physical damage.

In some embodiments, as shown in fig. 2, the lifting mechanism 2 may include a lead screw nut 21 and a screw 22. The screw nut 21 may be axially limited on the support 1, the screw 22 is in threaded fit with the screw nut 21, and the movement of the screw 22 along the axial direction may be controlled by the rotation of the screw 22 itself, or may be realized by the rotation of the screw nut 21. Meanwhile, the clamping part 3 can be connected to one end of the screw 22 close to the driving wheel, so that the stroke in the clamping operation is reduced when the screw 22 approaches to the driving wheel, and the clamping efficiency of the clamping part 3 and the driving wheel is improved. In other embodiments, the lifting mechanism 2 may also include a cylinder piston structure or a linear motor mechanism, and the clamping portion 3 is directly driven to move up and down by the cylinder piston or the linear motor.

For example, the screw nut 21 may limit the screw 22 at the center of the top surface of the support 1, so that the distances from the screw 22 to each supporting point in the horizontal direction are the same, so that when the screw 22 drives the driving wheel to lift through the clamping portion 3, the support 1 and a plurality of supporting points of the rolling machine track are balanced in stress, and physical damage to the driving wheel in the separation is avoided due to sliding of the support 1 in a certain direction in the lifting process of the driving wheel caused by uneven stress of each supporting point.

According to some embodiments, the screw 22 may be provided with a bearing 4 at one end near the driving wheel, as shown in fig. 2, the clamping portion 3 may be rotatably connected with the screw 22 through the bearing 4, so that the clamping portion 3 may keep free rotation relative to the screw 22, after the clamping portion 3 is clamped and fixed with the driving wheel, the clamping portion 3 may keep relatively static with the driving wheel without being affected by rotation of the screw 22, and only moves in a direction in which the driving wheel is separated from the roller bed rail under the lifting action of the screw 22, so as to realize the dismounting operation of driving the driving wheel to be separated from the roller bed rail.

For example, referring to fig. 1 and 2, the screw nut 21 may be fixed to the bracket 1, and at this time, the lifting motion of the screw 22 is converted by the rotation of the screw 22 itself, and in order to facilitate the rotation operation of the screw 22, a T-shaped handle 5 may be provided at an end of the screw 22 remote from the engaging portion 3, so that the screw 22 can be manually operated to rotate relative to the screw nut 21.

For example, the end of the screw 22 away from the clamping portion 3 may also be provided with a torque hexagonal bolt or a common special-shaped column head (not shown in the figure) so as to be adapted to the driving end of a common power device such as a torque wrench or an electric wrench, and the screw 22 can be driven in a manual alternative manner. Meanwhile, when the screw 22 is driven by the related power equipment, the torsional force can be detected, the output is ensured to be stable, the driving wheel in the disassembling process is further protected, and the equipment stability is improved.

In some embodiments, the clamping portion 3 may include two clamping plates 31 and two hooking claws 32. As shown in fig. 2, two clamping plates 31 are in clamping connection with the bearing 4 at one end of the screw 22 near the driving wheel, and are arranged on opposite side walls of the periphery of the bearing 4, so as to ensure that the clamping plates 31 can keep coaxial rotation with the bearing 4; the two hook claws 32 are respectively and rotatably connected to two ends of the clamping plate 31, so that the hook claws 32 are fixedly clamped with two sides of the driving wheel through rotation of the clamping plate 31 when the clamping part 3 approaches the driving wheel, and the two hook claws 32 are respectively separated from two sides of the driving wheel through rotation after the clamping part 3 drives the driving wheel to separate from the rolling machine rail so as to realize disassembly of the driving wheel. In this embodiment, after the hooking claws 32 are clamped and positioned with the driving wheel, the screw 22 can be rotated relative to the screw nut 21 by rotating the handle on the screw 22 and lifted in the direction that the driving wheel is separated from the roller track, at this time, the clamping plate 31 can keep the screw 22 in relative rotation in the horizontal direction by clamping action with the bearing 4 and only move in the lifting direction of the screw 22, and then the driving wheel is successfully separated from the roller track by lifting action of the hooking claws 32 clamped and fixed with two sides of the driving wheel, and after the driving wheel is separated, the hooking claws 32 can be separated from the driving wheel by rotating the two hooking claws 32.

Illustratively, the hook jaw 32 and the clamping plate 31 may be connected by a fastener extending through both the hook jaw 32 and the clamping plate 31, and the structure of the fastener is not particularly limited herein, including but not limited to the use of a set screw or pin or other common structural means to connect the hook jaw 32 to the clamping plate 31. It should be emphasized that, when the hook claw 32 is connected to the clamping plate 31 of the connecting piece, a certain clamping force should be provided between the hook claw 32 and the clamping plate, and when the hook claw 32 is connected to the clamping plate 31, the hook claw 32 cannot freely rotate relative to the clamping plate 31 without using external force for stirring, so that when the hook claw 32 is clamped to two sides of the driving wheel, the hook claw 32 cannot be naturally unhooked under the condition of being not interfered by external force, and the detachment safety of the driving wheel in the disassembling operation is ensured. Meanwhile, after the hook claw 32 is clamped and fixed with the two sides of the driving wheel, as the bearing 4 can rotate freely relative to the screw 22, and the clamping plate 31 is clamped and fixed with the peripheral side wall of the bearing 4, the clamping plate 31 and the hook claw 32 are not subjected to external force in the horizontal direction and are only subjected to the action of lifting force of the screw 22 along the separation direction of the driving wheel, and the hook claw 32 is not interfered by external force in the horizontal direction in the process of lifting the driving wheel, so that the clamping safety of the hook claw 32 and the two sides of the driving wheel can be ensured, and the driving wheel is prevented from falling off from the hook claw 32 under the natural condition.

In some embodiments, the bracket 1 may include a support plate 11, a support post 12, and a stopper 13. As shown in fig. 3, the support plate 11 is used for being fixedly connected and bearing a lifting mechanism, the support plate 11 is relatively perpendicular to the driving wheel along the direction of the falling rolling bed rail, so that the force applied when the driving wheel is disassembled is balanced, four support posts 12 can be fixedly arranged at the bottom of the support plate 11, are respectively connected at four corners of the support plate 11 relatively in parallel, extend from the support plate 11 to the rolling bed rail direction, can be clamped and supported on the rolling bed rail, and provide support points for the whole disassembling device. Meanwhile, the support column 12 can be provided with a limiting part 13 at one end far away from the support plate 11, and the limiting part 13 can be in plug-in connection with the roller bed rail so as to position the dismounting device on the roller bed rail, and ensure that the dismounting device can be stably abutted to the roller bed rail in the dismounting operation process and cannot move or shake, so that the overall stability of the dismounting device is improved.

For example, referring to fig. 3, the limiting part 13 may be constructed in an L-shaped structure, and one side of the limiting part 13 is abutted against the top end of the roller track and the other side can be abutted against the inner side wall of the roller track mounting driving wheel. One side of the limiting part 13, which is abutted against the side wall of the inner side of the driving wheel, of the roller bed rail is in clearance fit with the roller bed rail in a micro-size manner, so that the support column 12 can be supported and mounted on the roller bed rail, the abutting state of the limiting part 13 and the side wall of the inner side of the roller bed rail can be ensured, excessive shaking or integral sliding of the dismounting device in the process of dismounting the driving wheel by the external force driving lifting mechanism is prevented, and the integral stability of the dismounting device is effectively improved.

In some embodiments, the support plate 11 may further include a connection plate 111 and a hollowed-out portion 112. As shown in fig. 3, the screw nut 21 in the lifting mechanism may be relatively and fixedly connected with the support plate 11 by arranging a connection plate 111 penetrating through the center of the plane on the support plate 11, and the part of the connection plate 111, which is not fully connected with the support plate 11, is namely a hollowed-out part 112, and the hollowed-out part 112 can provide a wider line of sight for the clamping installation of the clamping part 3 and the driving wheel, so that an operator can observe and implement the clamping and fixing operation of the hook claw 32 and two sides of the driving wheel through the hollowed-out part 112. The specific shape and area of the hollow portion 112 are not limited, the hollow portion 112 can be symmetrically arranged on the support plate 11 at two sides of the connecting plate 111, so that the connecting plate 111 can be stressed and balanced on the support plate 11, the hollow portion 112 can ensure that an operator can observe the state of the clamping portion 3 at most angles through the hollow portion 112 in a normal disassembling process, and convenience is provided for practical disassembling operation.

According to some embodiments, the struts 12 may also be slidably connected to the plate 11. As shown in fig. 4, the supporting columns 12 can be slidably disposed on two sides of the supporting plate 11 along the plane of the supporting plate 11, where the supporting columns 12 should be slidably connected on two sides of the supporting plate 11 perpendicular to the extending direction of the rolling machine track, so that the distance between the supporting columns 12 can be adjusted by sliding the supporting columns 12 on the supporting plate 11, so that the supporting columns are adapted to the disassembling operation of the rolling machine driving wheels with different track distances, and the whole application range of the disassembling device can be improved. The connection manner of the strut 12 and the strut 11 is not particularly limited, and includes, but is not limited to, a sliding connection manner using a movable buckle, a sliding rail, or a simple sliding way. Further, it is also required to ensure that two pillars 12 on the same slat side of the supporting plate 11 and two other slat sides parallel to the roller track respectively slide at equal intervals, that is, the two pillars 12 on the same slat side need to slide reversely at the same time and have the same displacement distance, so as to prevent the sliding distances of the two pillars 12 on the same slat side from being unequal, and after the dismounting device is supported and positioned on the roller track, the integral center of gravity of the device is deviated, which causes the risk of overturning the device when the driving wheel is dismounted.

The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings, but the present disclosure is not limited to the specific details of the embodiments described above, and various simple modifications may be made to the technical solutions of the present disclosure within the scope of the technical concept of the present disclosure, and all the simple modifications belong to the protection scope of the present disclosure.
