Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.

Referring to fig. 1-2, the invention provides a device for quickly replacing wheels of an overhead crane, which mainly comprises two parts:

a first part: the anti-deviation device 5 is arranged on the wheel rail and used for preventing the crane wheels 2 from rolling on the wheel rail so as to ensure the safe disassembly of the fault wheels 10, the installation position of the anti-deviation device 5 is shown in figures 1 and 2, and two sides of two crane wheels 2 below the same wheel carrier 11 are respectively provided with one anti-deviation device 5 so as to ensure that the crane wheels 2 cannot move forwards or backwards;

a second part: the safe lifting locking device 6 is positioned between the crane wheels 2 and the crane body 1, particularly, the safe lifting locking device 6 is positioned right above the intact crane wheels 2 on the other side of the fault wheel 10 under the same wheel carrier 11, and meanwhile, the safe lifting locking device 6 has a lifting function so as to be capable of supporting the crane body 1 and avoid unstable shaking of the crane body 1 caused by the fact that the fault wheel 10 is detached; because the original balance between the crane wheel 2 and the crane body 1 is broken after the fault wheel 10 is removed, if the crane body 1 is not supported stably, the wheel carrier 11 on which the crane wheel 2 is mounted can lose balance under the heavy pressure of the crane body 1, and then the crane body 1 can be inclined, which is dangerous, therefore, considering that after the fault wheel 10 is removed, the side of the wheel carrier 11 positioned on the fault wheel 10 has no support of the fault wheel 10, the wheel carrier 11 can incline to the side of the fault wheel 10, the crane body 1 can be easily caused to shake, a safety lifting locking device 6 with lifting function can be placed between the wheel carrier 11 right above the intact crane wheel 2 and the crane body 1, the crane body 1 can be stably supported by the safety lifting locking device 6, and the danger of the crane body 1 inclination caused when the fault wheel 10 is removed can be avoided, the safety of the replacement work of the faulty wheel 10 is ensured.

The first embodiment is as follows: as shown in fig. 4-7, the anti-deviation device 5 is a stop 51, the stop 51 has a slope 56 that abuts the outer circumference of the crane wheel 2, in use, the stop 51 is placed on the wheel rail and the slope 56 abuts the outer circumference of the crane wheel 2, and then the stop 51 is fixed, thereby ensuring that the crane wheel 2 does not roll on the wheel rail.

In order to facilitate the installation and fixation of the stopper 51 on the wheel rail, a locking groove 52 for locking itself on the wheel rail may be provided at the lower part of the stopper 51, and the stopper 51 is locked on the wheel rail through the locking groove 52.

In addition, an anti-slip thread 57 may be provided on the groove wall of the slot 52 to enhance the anti-slip performance of the stopper 51.

As shown in fig. 8-10, the safety lifting locking device 6 includes a mounting box 61 fixedly mounted on the wheel frame 11, an upper surface of the mounting box 61 is open, a fixed block 63 is fixedly mounted on an inner bottom of the mounting box 61, an upper surface of the fixed block 63 has an inclined surface 56, a movable block 64 is slidably disposed on the inclined surface 56, an upper surface of the movable block 64 can contact with the crane body 1, a lower surface of the movable block 64 is also provided with an inclined surface 56, the inclined surface 56 of the movable block 64 is attached to the inclined surface 56 of the fixed block 63, the movable block 64 can slide up and down along the inclined surface 56, and when the movable block 64 slides up and down along the inclined surface 56, the upper surface of the movable block 64 contacts with the crane body 1 and pushes against the crane body 1.

In order to make the movable block 64 stably push against the crane body 1, the upper surface of the movable block 64 is preferably a horizontal surface.

In addition, the safe lifting locking device 6 also comprises a driving device which can push the movable block 64 to slide up and down along the inclined surface 56 in an inclined way and can lock the movable block 64 on the inclined surface 56 at any time without sliding;

specifically, the driving device is provided with a lead screw 65 penetrating through the fixed block 63 and a motor 62 which is arranged on the fixed block 63 and is used for driving the lead screw 65 to rotate, and the lead screw 65 is only connected with the fixed block 63 in a rotating and rolling manner and cannot move axially;

as shown in fig. 10, a first sliding groove 67 into which the screw rod 65 is inserted and capable of moving up and down is formed in the movable block 64, and the screw rod 65 can only rotate and move up and down in the first sliding groove 67 and cannot move back and forth, that is, the groove width of the first sliding groove 67 in the front-back direction is equal to the diameter of the screw rod 65;

the screw 65 is sleeved with a slide block 66, and the slide block 66 is only connected with the movable block 64 in a vertically sliding manner and cannot rotate, so that when the motor 62 drives the screw 65 to rotate, the screw 65 drives the slide block 66 to move along the screw 65, and then the movable block 64 is pushed to move obliquely upwards along the inclined surface 56.

The specific arrangement of the sliding block 66 in up-and-down sliding connection with the movable block 64 includes the following two ways:

1. the lower surface or front and rear side surfaces of the slider 66 are in contact with the mounting case 61, so that the slider 66 is prevented from rotating, and the slider 66 is in sliding contact with the outer side surface of the movable block 64;

2. a second sliding groove 68 for the sliding block 66 to slide up and down is formed in the outer wall of the movable block 64, and the sliding block 66 is inserted into the second sliding groove 68 and slides up and down along the second sliding groove 68; the sliding block 66 can be partially inserted into the second sliding groove 68, or can be completely positioned in the second sliding groove 68.

One end of the screw rod 65, which is far away from the motor 62, can be suspended and can also be movably inserted into the mounting box 61.
