Definitions

  • the switch controls the operation of a piston-cylinder arrangement such that when the switch contact is not engaged with the platform, the guide structure will be pivoted until the switch comes into contact with the platform, whereupon the piston-cylinder arrangement serves as a buffer resisting pivotal movement of the guide structure away from the platform.
  • this object is achieved by a device which comprises a structure hinged at one end and connected to an operating cylinder, as a result of which said structure may be swung about its hinge joint, said structure being provided near its other end with a contact element, a control device being employed for the pressure fluid for the operating above itsposition on the loading platform or when the,
  • the control device for the pressure fluid of the operating cylinder comprises a four-way slide valve in the supply and discharge pipes to and from the operating cylinder and a pipe by-passing said valve extending between the chamber at one side of the cylinder and the supply of pressure fluid, wherein a throttle element is provided.
  • the base member from which the structure is suspended may consist of a bridging beam between the legs of a container bridge.
  • Several spaced guiding devices may be mounted on said bridging beam of the container bridge so that containers of different lengths may be handled.
  • FIG. 1 is a side view of one embodiment of the device in accordance with the invention.
  • FIG. 2 isa diagrammatic view of the control device for the pressure fluid of the operating cylinder.
  • FIG. 1 illustrates a base member 1 which is part of a container bridge.
  • a structure 2 is mounted on said base I member 1, said structure 2 being permitted to swing about an axle 3.
  • An operating; cylinder 4 is also mounted on the base member I, and the piston rod of the cylinder is connected with the structure 2.
  • a contact element 5 is mounted at the lower end of the structure 2, element 5 being permitted to engage the loading platform 6 of a truck or similar vehicle.
  • a load (not shown) to be deposited on the loading platform 6 is suspended from the container-bridge above the platform and is slowly lowered onto the platform from the bridge, the load being guided by structure 2 in the four-way slide valve 7 in the supply and discharge pipes 8 and 9 of the operating cylinder 4.
  • a pipe 10 is provided by-passing the valve 7 and extending from the chamber at the left side of the piston in the cylinder 4 to the supply of pressure fluid 11.
  • a throttle element 12 isprovided in the pipe 10.
  • the contact element 5 When the contact member 5 engages the loading platform 6, the contact element 5 will be actuated, whereby the magnetic coil 13 will be de-energized and the four'way valve 7 will assume a central position in which the supply of the pressure fluid through the pipe 8 is cut off.
  • a safety device 17 When the magnetic coils l3 and 14 are not energized, a safety device 17 will operate on a low pressure. When energized, the overflow pressure of the device is increased. The piston will then act as a buffer because the pressure fluid in the chamber atthe left side of the piston can flow only through the by-pass pipe I0 and the throttle element 12 to the supply 11. The supply of the fluid to the chamber of cylinder 4 at the right side of the piston is effected through the pipe 15 having a non-return valve 16.
  • FIG. 1 It is within the contemplation of the invention to provide a plurality of traversely spaced guiding structures 2 between the legs of the bridge, all being pivotal about axle 3 under the action of a respective operating cylinder 4 and associated control device.
  • control means comprises a slide valve controlling flow of pressure fluid 'to and from the operating cylinder means.
  • control means comprises a supply pipe and a discharge pipe to and from the operating cylinder means and a supply of pressure fluid, said slide valve comprising a four-way valve controlling flow in said pipes in opposite directions of flow.
  • Apparatus as claimed in claim 3 comprising a bypass pipe connected to said operating cylinder means.
  • said operating cylinder means comprises a cylinder, and a double-acting piston in said cylinder defining chambers on opposite sides thereof, one chamber when pressurized acting on the piston to displace the guiding structure towards the platform,.the other chamber when pressurized acting on the piston to displace the guiding struc- I ture away from the platform,'said by-pass pipe being connected to said one chamber, and comprising throttle means in said by-pass pipe.
  • said main support comprises a bridging beam supported between I the legs of a container bridge.
  • Apparatus as claimed in claim 6 comprising-a'plu: rality of said guiding structures mounted in spaced rela-
