Definitions

  • the present invention relates to the field of presses for mounting and dismounting solid tires on and from rims, and more particularly to the field of portable presses for mounting and dismounting solid tires.
  • Presses for mounting a tire on a rim and for dismounting the tire from the rim are known.
  • the existing presses for mounting and dismounting solid tires are typically very large since a considerable pressing force has to be applied, usually in the range of 80-150 tons.

  • An example of using adaptors for mounting and dismounting a tire can be seen on the YouTube® net under "press solid tires Rodaco" by Rodaco industrial tires.
  • the most common adaptor comprises a first ring-like disc, a second ring-like disc, and a variety of round bars connecting therebetween.
  • this adaptor has a form of a round cage, and, therefore, hereinafter will be called a cage.

These arms slide within radially directed slots and are entirely manually adjusted to the desire radial position.

  • the hydraulic operating system 90 also operates the shoe adjustment piston 78.
  • the shoe adjustment piston 78 When it is desired to move the pressing shoe 44 radially inwardly, the shoe adjustment piston 78 is raised. Thus, by means of the connecting flange 82 and the connecting segment 84, the connecting arm 42 is pulled upwardly. Since the rear bore 56 of the leading bracket 38 is fixed within the internal bore 74 of the support bracket 32, the leading bracket can only rotate around the third arm axis C3. Thus, the front bore 54 of the leading bracket 38 goes under a combined rotational and translational movement within the opening 76 in the support bracket 32.

  • the shoe adjustment piston 78 When it is desired to move the pressing shoe 44 radially outwardly, the shoe adjustment piston 78 is lowered. By means of the connecting flange 82 and the connecting segment 84, the connecting arm 42 is pushed downwardly. Thus, in a process reversed to the described above, the pressing shoe 44 undergoes a radially outwardly movement as shown by the arrow RO in Fig. 3.

  • the dismounting steps are as follows:
  • the abutment cylinder provides space below the rim into which the removed tire will be loosened
  • a new tire is brought to the solid tire press and is ready for being mounted on the rim according to the following steps: a. Verifying positioning of the abutment cylinder on the press piston
  • a leading-expanding cone Positioning on the rim a leading-expanding cone. This step is not obligatory, however, it enables easy leading of the tire towards the rim and slight expansion of the inner perimeter of the tire during slidingly insertion on the rim.
  • the upper pressing arms 36 are short and sturdy, therefore enabling working with high working pressures, typically up to 100 tons, in a relative small size and in a safe manner.
  • the construction of the solid tire press 10 according to the present invention in contrary to prior art presses, enables the use of only one adaptor in order to mount and dismount a solid tire from a rim. Furthermore, this construction enables dismounting a tire without the need of using an additional plate in which upper arms may press thereon.
  • the radially adjusted sturdy pressing arms 36 by means of the pressing shoes 44, enable strong and efficient pressing on the inner layer of the tire, thereby preventing tearing the outer layer/layers of the tire, and eliminating the need to use additional instruments for scraping and removing tire residuals from the rim.
  • the vertical columns 12 of the solid tire press 10 are retractable, hence, the column lower section 16 and the column upper section 14 do not form a unitary piece.
  • the retraction of the vertical columns during transportation enables the following: (a) insertion of the solid tire press 10 through a rear opening of a small truck, a task that cannot be performed with presses known in the market due to their relatively large overhaul height dimension, (b) lowering the total center of gravity of the press and truck, a fact that increases driving safety and vehicle stability.
  • each column lower section 16 comprises a lower mounting bore 94 at the column lower section 16, and, an upper mounting bore 96, upwardly to the lower mounting bore 94.

If the solid tire press 10 is to be extended into a fully extended position or “working position”, than, the height fixing pin 100 is inserted into the upper mounting bore 96 of the column lower section 16.
  • the solid tire press 10 can be extended or retracted in two different manners: (a) by the aid of a forklift or an upper winch; the columns upper sections 14 and the structure therebetween (i.e., the supporting bridge 26, the support brackets 32, etc.) are slightly lifted in order to remove vertical pressure from the height fixing pin 100 until it can be pulled out from the current mounting bore (be it the lower mounting bore 94 or the upper mounting bore 96). Then, the columns upper sections 14 are lifted or lowered into the required position and then the height fixing pin 100 is inserted back again into the relevant mounting bore (the upper mounting bore 96 or the lower mounting bore 94) to lock the solid tire press 10 in its new required position.
