[0002] With the continuous development of social economy and the increasing level of science and technology, my country's port terminal industry is also booming. RTG, also known as tire gantry container crane, adopts gantry steel structure design, divided into trolley, car, lifting mechanism, among which RTG trolley is mainly responsible for the position movement control and drive in the direction of gantry. The driving device of RTG trolley generally includes motor, reduction box, small wheel and horizontal wheel, among which the horizontal wheel, as a guide device, can reduce the occurrence of rail gnawing phenomenon and plays an important role.
[0003] Regarding the above-mentioned related technologies, since the horizontal wheels of the trolley are generally equipped with bearings, when the bearings inside the horizontal wheels need to be disassembled, the relevant personnel need to hold the copper rod in one hand and make the bottom end of the copper rod against the top wall of the bearing, and then hold a hammer or other tools for striking in the other hand to strike the top of the copper rod, so that the copper rod drives the bearing to slide down and out of the horizontal wheel. Since the contact area between the copper rod and the bearing is small and the force of a single strike is difficult to control, the pressure on the bearing is often greater when the copper rod is struck, thereby increasing the chance of bearing damage. Utility Model Content
[0004] In order to reduce the probability of bearing damage when disassembling the internal bearings of the trolley horizontal wheels, the present application provides a special tool device for disassembling and assembling the horizontal wheels of an RTG trolley.
[0005] The present application provides a special tool device for disassembling and assembling the horizontal wheel of an RTG trolley, which adopts the following technical solution:
[0006] A special tool device for disassembling and assembling the horizontal wheels of an RTG trolley comprises a vertical frame, on which a mounting frame is arranged, and the mounting frame is used for installing the horizontal wheel. The vertical frame is also provided with a disassembly mechanism, and the disassembly mechanism comprises a disassembly frame and a driving member, wherein the disassembly frame is used to abut against the top wall of the bearing in the horizontal wheel, and the driving member is used to drive the disassembly frame to move downward, thereby pushing the bearing in the horizontal wheel to slide downward.
[0007] By adopting the above technical scheme, compared with the prior art, relevant personnel need to use tools such as copper rods and hammers to knock on the bearings in the horizontal wheel to separate the bearings from the horizontal wheel. The present application sets a vertical frame and a disassembly mechanism, so that relevant personnel can drive the disassembly frame to descend through a driving member, so that the disassembly frame abuts against the top wall of the bearing in the horizontal wheel, pushing the bearing to slide downward relative to the horizontal wheel, thereby realizing the disassembly of the bearing. Since the bottom wall of the disassembly frame abuts against the top wall of the bearing, the contact area is increased. At the same time, relevant personnel can also control the pressure applied by the disassembly frame on the bearing by controlling the speed of movement of the disassembly frame, thereby reducing the pressure on the top of the bearing and reducing the probability of the bearing being damaged due to excessive pressure.

At the same time, the presence of the positioning component can also clamp horizontal wheels of different diameters, thereby increasing the usability and scope of application of the present application.
[0012] Preferably, a rubber pad is further provided at the bottom of the placement cylinder, and the top wall of the rubber pad is in contact with the bottom wall of the horizontal wheel.
[0013] By adopting the above technical solution, the setting of the rubber pad can effectively protect the bottom of the horizontal wheel and effectively reduce the probability of wear of the bottom of the horizontal wheel due to excessive force between the bottom of the horizontal wheel and the bottom wall of the placement tube.
[0014] Preferably, the driving member comprises a screw jack, which is mounted on the top of the stand, and the top plate of the screw jack is arranged downward and connected to the disassembly frame.
[0015] By adopting the above technical solution and the specific setting of the driving member, relevant personnel can operate the screw jack so that the top plate of the screw jack drives the disassembly frame to move downward, thereby realizing the driving of the disassembly frame.
