Definitions

  • the invention relates to a device and a system for receiving and transporting loads, which is or is to be attached to another device.
  • This device can be a stationary or movable device, whereby the movable device can be, for example, a vertically movable lifting carriage of an industrial truck.
  • Such devices for picking up loads can, for example, be integrated into an industrial truck or designed as an attachment that is attached or is to be attached to a device such as a forklift truck. They usually have two or more load-carrying elements that can move relative to one another and, for example, can have the form of two fork tines that can move relative to one another.
  • This mobility of the fork tines is achieved by appropriately designed adjustment devices and enables users to adapt the fork tines to the width of an object to be picked up or to recesses in it into which the fork tines engage.
  • the load-handling elements can not only be moved towards and away from each other, but also both can be moved parallel and simultaneously in the same direction in order to compensate for an inaccurate approach with the industrial truck without having to maneuver the entire vehicle.
  • This sideshift movement is made possible by the same drive elements as the movement of load-handling elements towards and away from each other.
  • the respective adjustment devices are operated by the operator of the industrial truck from the workplace without him having to get off.
  • a device for transporting loads which comprises two load-bearing elements, each of which is attached to horizontally movable sliding arms which can be moved relative to one another by drive elements, wherein the sliding arms are mounted on at least one sliding guide body and can be moved along a sliding guide body by the drive elements.
  • the load-bearing elements are additionally each attached to movable guide arms which are guided on a guide rail, wherein the sliding guide body and the guide rail are connected to one another by two connecting elements and spaced apart from one another.
  • the drive elements are partially arranged inside the sliding guide body and the sliding arms are movably guided within the sliding guide body, wherein the sliding guide body has a longitudinal slot through which a connecting section of the sliding arm protrudes from the sliding guide body and is connected to a load-bearing element.
  • the sliding guide body thus at least partially encompasses both the drive elements and the sliding arms, so that these are advantageously protected in a sliding guide body, which also serves to guide the sliding arms. Damage and failure of the industrial truck can thus be reduced and maintenance costs remain low.
  • the device can be designed to be compact, thus ensuring a good view from the operator to the load-handling elements and being able to be manufactured inexpensively.
  • a fork positioning arrangement for mounting on a lift truck comprises a first fork positioner and a second fork positioner, the fork positioners being connected to a fork frame.
  • the first fork positioner is constructed essentially as a mirror image of the second fork positioner.
  • Each fork positioner comprises a tube with an internal cavity in which a piston and a carrier are arranged, both of which are coupled to a rod. The piston and the carrier are both in sliding contact with the tube.
  • Each fork positioner has a fork holder arranged outside the tube, the fork holder being coupled to the carrier through a slot in the tube.
  • the part of the carrier coupled to the fork holder is located between a first carrier bushing and a second carrier bushing. Due to the fork frame, the fork positioning arrangement is quite large, reducing the free cross-section between the fork positioners and thus the visibility for an operator of an industrial truck to which the fork positioning arrangement is attached.
  • the device comprises at least two load-bearing elements, each of which is attached to horizontally movable sliding arms, which can be moved relative to one another and as a side thrust parallel in the same direction horizontally in or against the x-direction by at least two drive elements, wherein the sliding arms are mounted on a common upper sliding guide and the load-bearing elements are guided on a common guide rail in the y-direction below the sliding guide, wherein the at least two drive elements for the horizontal movement of the load-bearing elements relative to one another are designed as movable sliding arms and the at least two drive elements are each connected to a connection head via a piston rod and for the parallel movement of the load-bearing elements in the same direction, the at least two drive elements are connected via a simultaneous drive of the connection heads be moved together horizontally in or against the x-direction.
  • the fork unit comprises a frame engaging the lower and upper edges of a plate member mounted on the front end of a forklift truck and accommodating a plurality of forks, the frame being displaceable in a direction substantially parallel to the plate member by means of a hydraulic cylinder acting between the plate member and the frame, the frame having a pair of vertically spaced and transversely extending upper and lower support beams fixedly connected to one another by a pair of spaced vertical side members, the upper support beam of which is substantially inverted U-shaped so as to be displaceable on an axis fixed to the upper edge of the plate member, the forks each having a vertically extending leg portion substantially in the same plane as the frame and a horizontally extending tine portion, the lower ends of the leg portions being displaceable along the lower support beam of the frame, while the upper ends of the leg portions are behind a projection of the upper support beam so as to enable the forks to move back and forth along the lower support beam, and means are provided between the upper support beam and the upper ends of the
  • the object of the invention is therefore to provide a device for receiving loads which improves the device known from the prior art in that standard load-bearing elements can be used at the same time and the free cross-section for the view of an operator of the industrial truck on which the device is mounted is maximized, the device being compact and having a low construction depth.
  • a further object of the invention is to provide a system for receiving and transporting loads for installation on mobile or stationary devices.
  • this object is achieved by a device having the features of independent claim 1.
  • Advantageous further developments of the device arise from the subclaims 2-18.
  • the further object is achieved by a system according to claim 19.
  • An advantageous further development of the system arises from claim 20.
  • a device according to the invention for picking up and transporting loads can be mounted on a movable or stationary device.
  • a movable device can be, for example, an industrial truck such as a forklift truck.
  • a stationary device can be, for example, a stationary lifting device.

The distance between the load-bearing elements can be changed by moving relative to one another.
  • a movement parallel to one another represents a so-called side-shift movement, via which, for example, a forklift operator can pick up or put down a load without having to maneuver the forklift truck precisely, by being able to move the load-bearing elements to pick-up points of a load that correspond to the distance between the load-bearing elements but are not exactly at the positions of the load-bearing elements.
  • the device according to the invention is characterized in that the first guide profile has a hollow profile and a drive element is at least partially integrated in the first guide profile inside the guide profile, wherein a drive plate is operatively connected to the drive element and the guide of the drive plate is also at least partially integrated and mounted in the guide profile, wherein the drive element and the guide of the drive plate are on one axis, wherein the first guide profile has a longitudinal slot through which the holder of the drive plate protrudes, wherein a load-bearing element can be operatively connected to a drive plate. Due to the position of the drive element inside the first guide profile, the drive elements are well protected against external influences.
  • the load-bearing elements can be easily inserted into the drive plates, so that standard load-bearing elements such as standard fork tines can be used, which can nevertheless carry out lateral movements relative to one another or parallel to one another. Due to the integration of the guide and By storing the carrier plate in the first guide profile, the size of the device is minimized and the cross-section for the view of an operator of an industrial truck is maximized.
  • the first guide profile forms the supporting structural element. In other words, the first guide profile carries the at least two load-bearing elements. A further supporting structure is not required, which means that the inventive device is extremely compact and has a low structural depth.
  • the device has, in addition to the first guide profile, a second guide profile arranged essentially parallel to the first guide profile, wherein the guide profiles are connected to one another at a distance from one another via at least one connecting element arranged essentially perpendicular to the guide profiles.
  • the at least one connecting element can form a frame construction with the guide profiles, whereby the device can be mounted as an attachment on, for example, a forklift truck.
  • vertically arranged mast cheeks which are mounted directly in the lifting frame of the industrial truck, form two connecting elements and, together with the two guide profiles, a frame that stabilizes the device.
  • the second guide profile can have a hollow profile just like the first guide profile, whereby a drive element can be at least partially integrated in the interior of the second guide profile, whereby a drive plate can also be operatively connected to this drive element and the guide of a drive plate can also be at least partially integrated and mounted in the second guide profile, whereby here too the drive element and the guide of the drive plate lie on one axis, whereby at least the second guide profile also has a longitudinal slot through which the holder of a drive plate protrudes.

  • At least one drive element has a spindle, for example a ball screw.
  • At least one drive element has a fluid cylinder, for example a hydraulic or pneumatic cylinder.
  • the drive unit has a hydraulic motor.
  • the drive unit has an electric motor.
  • a drive unit drives one or two drive elements.
  • the drive unit can be arranged centrally in a guide profile, for example in the first guide profile, and drive two drive elements that are arranged on both sides of the drive unit in the direction of the guide profile. This can be done via a gear or directly. If the drive unit and the two drive elements that are operatively connected to the two drive plates are arranged in just one guide profile, the second guide profile only serves to support and guide the load-bearing elements. This can be done directly or indirectly via the drive plates. However, it is also conceivable to be able to dispense with a second guide profile, for example by making the first guide profile larger and more stable.
  • both guide profiles each have a drive element.
  • Both guide profiles can have a drive unit. It is also conceivable that only one guide profile has a drive unit or that no guide profile has a drive unit.
  • the drive of the carrier plates is possible via fluid cylinders with pistons and piston rods, whereby the fluid can be, for example, compressed air or hydraulic fluid, which is provided by a central system, for example the hydraulic unit of an industrial truck on which the device is mounted.

  • Ball screws or threaded spindles can be used, for example.
  • a hydraulic motor or an electric motor is advantageous for driving a rotary drive element or for driving two rotary drive elements in parallel. If two rotary drive elements are connected to only one drive unit, the direction of movement of at least one drive element can be reversed by interposing a gear, in particular a switchable gear, between the drive unit and at least one drive element, while the second drive element continues to rotate in the same direction. This enables the drive plates to move in opposite directions towards or away from each other, as well as the drive plates to move in the same direction in the form of a side-shift movement.
  • the interposition of a gear for the two types of movement of the drive plates in relation to each other is not necessary.
  • the combination of different drive units is also conceivable.
  • the combination of different drive elements for example a spindle and a linear cylinder, for example a fluid cylinder in the form of a pneumatic or hydraulic cylinder, is also conceivable.

  • the guide slots point forward, i.e. in the direction of the load-handling elements or in the direction of travel of the industrial truck.
  • the two guide profiles are arranged essentially horizontally one above the other, so that the first guide profile is above the second guide profile and the longitudinal slot of the second guide profile is on the upper side of the second guide profile in the direction of the first guide profile, the longitudinal slot of the second guide profile being closed off by a protective element, for example a strip, that moves with the drive plate.
  • the horizontal arrangement of the guide profiles one above the other is the usual arrangement for attaching the device to a forklift truck, for example.
  • the longitudinal slot of the lower, second guide profile points upwards.
  • the protective element which moves with the drive plate, closes this longitudinal slot at the top, so that the risk of contamination is minimized.
  • the longitudinal slots have a length that corresponds to the maximum travel path of the drive plates.
  • the drive elements have fluid-operated cylinders, each with a cylinder housing and a piston rod, with fastening means and guide means for the respective drive plate being at least partially integrated into the respective cylinder housing.
  • Pressurized hydraulic oil is usually provided to a forklift, so it is advantageous to design the drive elements as hydraulic cylinders.
  • connection head By integrating the fastening and guide means for the carrier plates into the cylinder housing, components are saved and the size is further minimized, which further maximizes the free cross-section for the view of an industrial truck operator. Another advantage is that the connections to the hydraulic cylinder are located directly next to each other via a connection head, which minimizes the effort required for the hydraulic connection.
  • Pneumatic cylinders can also be used as drive elements.
  • the invention also includes other drive elements, such as electrical drive elements.

Wear elements can also be attached here.
  • At least one guide profile encompasses more than half of the drive element arranged inside it. It has proven to be particularly advantageous if both guide profiles encompass more than half of the respective drive element. It has also proven to be particularly advantageous if the degree of encirclement of at least one guide profile is more than 75%.
