Description

Technical Field

[0001] The utility model belongs to the technical field of cableway disassembly tools, and in particular relates to a disassembly and assembly mechanism for a cable wheel on a reciprocating cableway. Background Art

[0002] The cable pulley used on the reciprocating ropeway will wear out after a certain period of use. When the rubber wheel lining on the cable pulley is worn out and the rope groove depth exceeds the radius of the carrying rope, the rubber wheel lining needs to be replaced.

[0003] The current cable wheel disassembly and assembly tool is a rack. The force plate for disassembling and assembling the cable wheel lining needs to be lifted onto the disassembly and assembly rack, and then the disassembly and assembly rack needs to be lifted down after the disassembly and assembly is completed. The weight of a force plate is nearly 120 pounds, and three people need to lift it together in a small space to put it on the jack under the rack for disassembling the cable wheel lining. At the same time, one person needs to observe and make sure that the jack is placed in the middle of the force plate. Moreover, when the cable wheel force plate is pushed up with the jack, the bottom is very unstable, and someone needs to straighten it to prevent it from sliding off. Once it slides off, it will hurt the operator's hands and feet, which is very unsafe. In addition, it takes 1.5 hours to disassemble and assemble a cable wheel lining, which is time-consuming and laborious. Therefore, it is necessary to propose improvements. Utility Model Content

[0033] When the utility model is used:

[0034] 1. Removal of the rubber wheel village of the cable wheel

[0035] Step 1:

[0036] (1) Place the cable pulley 14 on the lower pressure plate 8;

[0037] (2) Use the jack to press the rubber wheel liner 14-2 until the snap ring 14-4 is loose and can be removed; after removing the snap ring 14-4, release the pressure of the jack to lower the lower pressure plate 8 and remove the side plate 14-3. (I think the operation here is not complete, please ask the technician to add some explanation.)

[0038] Step 2:

[0039] (1) Place the guide cone 13 on the lower pressure plate 8

[0040] (2) Place the cable pulley 14 on the guide cone 13, ensuring that the two are concentric and that the side with the side plate 14-3 is on top. Use a jack to move the lower pressure plate 8 and the guide cone 13 upward. The edge of the central circular hole of the upper pressure plate 5 is pressed on the rubber wheel liner 14-2, so that the guide cone 13 pushes against the wheel hub 14-1 and comes out of the rubber wheel liner 14-2 and the side plate 14-3.

[0041] 2. Installation of rubber wheel lining

[0042] Step 1:

[0045] (3) Flatten the rubber wheel liner 14-2 onto the top of the guide cone 13

[0046] (4) Use a jack to press upward, and the edge of the central circular hole of the upper pressure plate 5 presses on the rubber wheel liner 14-2. Continue to press until the rubber wheel liner 14-2 passes through the guide cone 13 and slides onto the wheel hub 14-1. The rubber wheel liner 14-2 must be firmly pressed against the lower side plate 14-3.

[0047] (5) Release the pressure of the jack to lower the lower pressure plate 8 and remove the guide cone 13.

[0048] Step 2:

[0049] (1) Place the second side plate 14-3 on the rubber wheel liner 14-2, and press the rubber wheel liner 14-2 with a jack until the snap ring 14-3 on the side plate 14-3 can be installed;

[0050] (2) Release the pressure of the jack to lower the lower pressure plate 8, and the compressed rubber wheel liner 14-2 causes the side plate 14-3 to press against the retaining ring 14-4, so that the rubber wheel liner is installed in place.

[0051] (3) The two snap rings 14-4 must be correctly installed in the snap ring grooves of the wheel hub 14-1.

[0052] The utility model has a simple structure, is easy to use, reduces the time for disassembly and assembly, and eliminates potential safety hazards in the operation process.
