Definitions

  • the present invention relates to a set-up device for scissor lifts, in particular for the lifting of motor vehicles, which requires a reduced force to lift in the initial phase of the lifting movement and generates a low mechanical load on the set-up.
  • the scissor lift has a compact design in the retracted position.
  • Scissor lifts are used in various technical fields for lifting various loads and possibly even people. Different versions of scissor lifts are also used for lifting motor vehicles, especially cars, SUVs and vans, repair shops, manufacturing plants and also in testing operations, due to the simple Hub technology, the robust design and the possibility of a floor level arrangement of the scissors lift ,
  • At least two congruent shears are used for the construction of the lifting mechanism. If particularly high heights can be reached, then one can arrange several such pairs of scissors one above the other, resulting in, for example, double scissor lifts or multiple scissor lifts.
  • Scissor lifts are in the deflated state have the lowest possible height to facilitate the application of the loads to be lifted in this position.
  • the lifts for motor vehicles should protrude in their lowered position as little as possible on the bottom surface, so as to facilitate the driving of the vehicles.
  • it can also account for a special pit at the construction site.
  • U.S. 4,858,888 describes a lift with a mechanism comprising a safety assembly for connecting a piston rod of a hydraulic cylinder to components pivotally mounted to a chassis.
  • WO 01/27499 A1 describes a scissor lift in which in a folded position, a hydraulic cylinder does not protrude beyond the height of the folded scissor arms.
  • DE 29920934 U1 shows an erection mechanism for a scissor lift, which allows by means of a spreading lever, two rolling elements and a stop plate a larger angle between the lifting cylinder and scissor spar and thus a more favorable lever attack ratio and easier installation of the scissor lift.
  • shown form of the expansion lever leads to a high material tension, especially at the areas that are in contact with the stop plate. This leads to a high material stress or a high mechanical load and requires in connection with the rolling bearings a comparatively expensive production. Another disadvantage is the noise generated by the expansion lever on the stop plate.
  • the setting-up device for scissor lifts comprises at least two intersecting scissor beams, a linear actuator for lifting the scissor struts, a double lever joint, which is pivotally mounted on a scissor stay, wherein the double lever joint couples the lifting movement of the linear actuator to at least one scissor stay.
  • the double lever joint allows a particularly advantageous lever ratio when lifting a scissor lift from a lower retracted position.
  • the double lever joint according to the invention consists of a first and a second lever element, which communicate with each other. The first and the second lever element are pivotally mounted in their connecting region about an axis.
  • a scissor beam is pivotally connected at a first location to the first lever member and pivotally connected at a second location to the second lever member.
  • the scissor lift may comprise a further pair of intersecting scissor beams, which is also connected to the double lever joint.
  • the first pair of scissor bars can be on the left and the second pair of scissor bars on the right side of the double lever joint.
  • the double lever joint may be located between the two pairs of scissor bars and articulated therewith.
  • the pivot axis ie the common pivot axis of the first and second lever element of the double lever joint, mounted in a slot of the first lever member, wherein the extension of the linear actuator in the first extended position shifts the pivot axis along the slot.
  • the leadership of the pivot axis through the slot of the first lever member allows a particularly quiet, predetermined erection of the lever member.
  • the end portion of the slot is an anchor point, which can be dispensed with a separate, known from the prior art on the scissor bar stop plate. Reaching this stop position of the slot determines the achievement of the first extended position.
  • an extension of the linear actuator from a lower rest position into a first extended position can produce an erection of the second lever element relative to the extension direction of the linear actuator and relative to the longitudinal axis of the scissor spar.
  • This arrangement of the first and second lever element enables a particularly efficient coupling of the lifting movement of the linear actuator to a scissor beam with an advantageous angle of attack during the lifting phase of the scissor lift from a lower resting state.
  • the first and / or the second lever element may each consist of two parallel arranged lever plates, which are each arranged pivotably and in parallel via hinge pins.
  • the two lever plates of the first lever element may each be hinged at one of its end regions to a scissor spar, while in a second end region they are in communication with the extendable piston head of the lifting cylinder on opposite sides.
  • the two lever plates of the second Hebelelemerits can be arranged parallel and equidistant from each other via a hinge pin and hingedly connected via this hinge pin with a scissor stay of the scissor lift while simultaneously pivotally mounted with an end portion of the lever plates of the first lever member.
  • the second lever element can be movably mounted on a guide element in a second end region, wherein the extension of the linear actuator into the first extended position produces an opposite movement of the second end region of the second lever element.
  • This guide element may be a guide plate attached to the scissor spar.
  • the second lever element may be slidably mounted on the guide plate via a thrust element articulated on the second end region.
  • the second lever element consists of two parallel lever plates
  • two push elements can be pivotally attached to each end region of the lever plates.
  • the guide plate can have a central recess have for receiving the second end portion of the second lever member during extension of the linear actuator in the first extended position.
  • a thrust element may be pivotally mounted at the second end region between the lever plates, wherein the guide plate has a central recess for receiving the thrust element during extension of the linear actuator in the first extended position.
  • the lever plates of the first and of the second lever element in the plan view have the shape of an elongate rectangle with strongly rounded end regions. Furthermore, the lever plates may have recesses along the longitudinal axis for receiving a respective pivot pin.
  • a scissor lift comprises at least one setting-up device according to the invention.
  • four set-up devices can be used for a scissor lift, wherein two of the scissor beams are each assigned to a running surface.
  • the present invention provides a scissor lift assembly which allows for reduction of lift force during deployment from a lower retracted position.
  • the erection device according to the invention is realized by cost-effectively erecting components, which include the double lever joint, the guide plate and the pushers. Become the components can be realized with high stability, at the same time allow a very quiet Aufraumsvorgang and ensure low mechanical stress on the installation components.
