Definitions

  • the present invention relates to a device for transporting shaped stones or shaped stone slabs according to the preamble of patent claim 1.
  • transport devices in the manner of a forklift have become known, which have a height-adjustable gripping and lifting system on a frame, for example in the form of gripping tongs or the like, on the frame in cooperation with a counterweight or a spring is guided in such a way that the gripping and lifting system is pulled upwards by the counterweight in the empty state and is pulled down in the loaded state, that is to say after gripping a shaped block or a shaped stone plate.
  • a manually releasable braking system is provided, with which, for example, the hoisting and lifting system can be started up in the unloaded state via a hoist, but also the lowering of this gripping and lifting system can be released or interrupted arbitrarily in the loaded state.
  • the gripping and lifting system can only be raised by the counterforce to such an extent that the height is given in which the next slab is to be picked up and lifted from a stack.
  • the frame is then inclined in such a way that the gripping and lifting system lowers over the next plate of a stack, grips it and is lifted from the stack by re-erecting the frame.
  • the brake is then released at the installation location and the plate sinks down to the desired location with the gripping and lifting system. There the plate is released and the spring or the counterweight raised due to the lowering pulls the gripping and lifting system upwards, provided that this movement is not slowed down.
  • the object of the invention is to provide a device of the type mentioned, which is of simple construction, which enables the stones to be picked up and put down without any particular effort, is easy to handle and which guarantees high operational reliability.
  • the gripping and lifting system which grips and holds it in a manner known per se when the gripper is placed on a shaped stone plate in the manner of a gripping excavator, is assigned a gas pressure spring as an energy store, the weight of a plate to be installed the gas pressure spring is tensioned so that the lifting and gripping system is pulled up again after relief by the force of the gas pressure spring.
  • the downward movement acts on the gas pressure spring via a brake connected to a roller and / or the drive side of the clutch, which simultaneously serves as a damper for the movement.
  • the gripper is guided on rollers, the rollers being positively guided along two guide rods, which guarantees low-friction and faultless guidance even in rough operation and in unfavorable weather conditions.
  • the gas spring representing the energy accumulator can act on a cable or chain hoist on the lifting and gripping system guided as a slide or directly on it, this spring being used in such a way that the gas is compressed when the lifting and gripping system is lowered and during expansion this lifting and gripping system pulls or pushes upwards.
  • the gripping and lifting system is guided according to an advantageous embodiment of the invention by means of a chain, which is guided over a chain wheel arranged on the top of the frame, which is coupled to a shoe or disc brake.
  • the brake can be inserted and released with the help of a hoist that the operator operates.
  • the gripping and lifting system shown in Fig. 1 is generally designated 1. It is constructed in a basic design known per se and works in the manner of a snap lock with a sensor in such a way that the pliers-like gripper is first opened when it is lowered by a sensor and is closed by the train when it is raised again.
  • the entire gripping and lifting system 1 depends on a crossbar 2, which is supported by a rod 16, with which it is jointly attached to a vertical guide system 3, which slides on two parallel guide rods 4 and 4 'with the help of rollers.
  • the guide system 3 hangs on a chain 8, which is guided via a chain wheel 9, which is connected to a disc brake or drum brake, not shown.
  • the brake in connection with the sprocket 9 can be released via a cable pull 10 depending on an operation of the operator on the lever 11 against the force of a spring 14, which is fixed on one side to an abutment 13, via a brake lever, which is not specified in detail.
  • the entire device can be moved using the linkage 12.
  • the device according to the invention is used in such a way that the operator first moves the entire device to a stack of shaped stone pallets, where the holding and lifting system can drop by tilting onto the uppermost pallet, and this upper plate is raised for gripping. The brake is therefore blocked. Then the entire device is pushed to the storage place (relocation point).
  • the frame which can be constructed, for example, as a frame 23 (FIG. 4), two gas pressure springs 15 are attached next to one another, which are rigidly connected at their lower end, in the region of the end of the piston rod, to a deflection wheel 21, which is only indicated schematically.
  • the gas springs push the deflection roller 21 down again and thereby lift the now much lighter lifting and gripping system 1 until the operator stops the upward movement by applying the brake.
  • the trolley can be guided back to the stack of stones with the lifting and gripping system raised and the stone slab can be picked up.
  • the process described is repeated, the gas springs being set so that when the lifting and gripping system is loaded, the gas pressure spring is compressed and when it is relieved it can relax again.
  • the lifting and gripping system can be guided on a corresponding endless chain and the gas pressure springs can be arranged on the side of the lowering of the lifting and gripping system and act directly on the slide.
  • the chain is only used for the holding and braking processes, while the pressure of the lifting and gripping system is exerted directly on the gas pressure springs when lowering and on the other hand by the gas pressure springs on the spring and brake system when lifting.
  • the only decisive factor is that the movement of the lifting and gripping system, which is controlled in a weight-dependent manner by means of the gas pressure springs, can be clearly locked in any end position and in particular also in every intermediate position by means of a brake.
