Definitions

  • the invention relates to a lifting jack for supporting and allowing the handling of mechanical components under an elevated vehicle or apparatus.
  • lifting jacks designed to lift or support various parts, parts or components of vehicles or other devices are known, facilitating their handling. These lifting jacks are devices commonly used in mechanical workshops to perform maintenance, inspection, assembly, disassembly, installation, uninstallation or repair of specific components of a vehicle characterized by the fact that in order to access them it is necessary that the vehicle is elevated . Some examples of these components are the gearbox and the transmission.
  • the lifting jack Prior to handling the vehicle component, the lifting jack must be placed under the vehicle. To allow the lifting jack to be placed under the vehicle, the vehicle must be previously elevated at a sufficient height to be able to introduce the lifting jack under it. For this, the vehicle is usually located on a pit or on specific column elevators for lifting vehicles. Likewise, the vehicle must be adequately secured or fixed so that it cannot move while handling the component.
  • Professional lifting jacks for work in trenches or under elevated vehicles, generally consist of a base equipped with wheels to facilitate the movement of the lifting jack on the ground, a lift support or lifting support intended to receive, hold and / or accommodate the component of the vehicle to be handled and a drive system, for example of hydraulic type. Said drive system enables both the lifting of the support to a working area under the vehicle and the recoil or lowering of the support.
  • the hydraulic system drive for lifting and lowering the support is usually implemented by manual or pedal levers.
  • the present invention aims at a lifting jack that reduces the risk of damage to the component to be handled when the component is deposited in the lifting jack or is temporarily housed or held by a lifting jack in order to handle the component.
  • the object of the invention is a lifting jack, to support and allow the manipulation of a component of a vehicle or apparatus, with a base provided with wheels to allow the lifting jack to move on a floor, a tubular body with a lower end and a upper end and a support to hold and allow the manipulation of the vehicle or device component.
  • the base is attached to the lower end of the body and the support is attached to the upper end of the body.
  • the lifting jack comprises a telescopic body comprising in its interior a piston for detachably joining the body with the support, and a support comprising a rigid part joined to a flexible part, where the rigid part comprises a claw provided with at least one pair of hooks with an arched base and arranged facing each other, and where the flexible part is formed by a deformable material.
  • Both the rigid part and the flexible part comprise at least one hole to receive the piston, where both holes are matching and of different diameters to retain the piston in two different positions:
  • the configuration of the lifting jack of the invention allows the jack to be able to hold and manipulate both conventional components and delicate components or that can present delicate parts.
  • the first position will allow the cat to hold and manipulate conventional components
  • the second position will allow the cat to hold and manipulate delicate components without damaging them.
  • the flexible part of the support being a deformable material and presenting a lower stiffness than the rigid part, has the capacity to absorb impacts or vibrations.
  • the use of the lifting jack according to the invention prevents damage to the component even if this component has delicate parts.
  • the connection of the support in the first position, with the rigid part arranged at the upper end of the lifting jack, is reserved for the handling of robust components of the vehicle or manipulations that require and allow the application of a higher force.
  • the configuration of the support allows it to be fixed in two different positions depending on whether it is to perform a protective function or a function of resistance to the application of a force. This double functionality is advantageous in the daily use of lifting jacks, making the cat more versatile to hold or come into contact with components of different nature or to allow different types of manipulations.
  • Another advantage of the described support is that, by having a flexible protective part comprised or integrated in the support, it is achieved that the positioning of the flexible part within the lifting jack is very stable and therefore the Delicate component is held safely and with a reduced risk of falling.
  • the integration of the flexible part in the support is also advantageous because it does not carry risks of the flexible part being lost.
  • the lifting jack according to the invention constitutes an alternative that allows the manipulation of components of vehicles of robustness or variable resistance or that present delicate parts in a comfortable, practical way and with a simple assembly .
