Definitions

  • the invention relates to a device for transporting and laying shaped stones and stone slabs, which are individually removed from a stack and transported to the installation site, with a horizontally projecting gripping and lifting system, which is vertically displaceably mounted on a vertical frame guided on wheels Height-adjustable by means of a tension member which is guided over a deflection roller mounted at the upper end of the frame and can be influenced in its movement by means of a braking system in cooperation with a spring element designed as a gas spring.
  • Such a device is known from FR-A-2 381 133.
  • This device essentially works by means of a hydraulic cylinder, however, an existing pressure accumulator, which can also be designed as a gas spring, only fulfills an additional function. It is true that the extension arm is raised and lowered by means of a traction cable, this traction cable being guided over a roller which is attached to the upper end of a hydraulic cylinder. When lowering, the hydraulic cylinder also moves downwards and presses the hydraulic fluid into a cylinder, from where the energy accumulator is then activated.
  • such hydraulic cylinders are somewhat susceptible to operation and also require additional lubricants, so that they are therefore not very environmentally friendly.
  • the present invention has for its object to provide a device of the aforementioned type, which is simple in construction, which allows the stones to be picked up and put down without any particular effort and which, with easy handling, has a high level of operational safety without possible environmental pollution.
  • At least one gas spring is fixed vertically in the frame with its gas cylinder and the free end of the downwardly extendable piston rod of the gas spring is in operative connection with the tension member designed as a chain.
  • the lifting and gripping system is thus directly coupled via a chain to the piston rod of a gas spring, which is activated when the lifting system is lowered, the lifting system can be automatically opened again.
  • a gas spring By using a gas spring, a largely trouble-free and very environmentally compatible arrangement is created, which is also very simple, robust and immune to failure.
  • Two gas springs arranged in parallel are expediently provided, the piston rods of which are connected to one another by an axis carrying a further deflecting roller, via which deflecting roller the chain is guided.
  • the chain can be fixed above the lower deflection roller on the frame itself, wherein the deflection roller can also be designed as a sprocket.
  • the brake system is expediently designed as a drum brake, which brake can be inserted by means of a spring and can be released by hand using a Bowden cable.
  • 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 20 .
  • 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 chain wheel 9 can be released via a Bowden cable 10 depending on an actuation 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 springs are compressed and when the load is off they 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.
