Definitions

  • the invention relates to a conveyor, in particular a hoist with a sprocket passing through it chain drive driven by a motor which through a chain guide to prevent it from jumping off the sprocket is secured and that of the chain guide at least one switch or sensor is assigned, if at least part of the position changes the chain guide the drive motor of the conveyor switches off.
  • a chain conveyor is the above kind of an essentially U-shaped Known chain guide, which is pivotally mounted on bushings which is the drive shaft for the sprocket a chain strand consisting of round steel links enclose.
  • the sprocket is supported in this construction about rolling bearings inside the already mentioned Bush and has a hole through which the shaft of a drive motor protrudes, which is a gear is connected downstream, the output pinion with a gear meshes with the sprocket connected is.
  • the well-known construction can not fully satisfactory in that their structure is complicated and time-consuming.
  • the invention has for its object a conveyor of the kind contemplated to create the Advantages of a perfect chain guide with the Advantages of a simple structure combined.
  • This object is achieved in that the chain guide next to a fixed guide section one that moves back and forth between two positions, to operate the switch or sensor serving and designed as a one-armed swivel lever Has guide element, its its pivot axis opposite end in the area of the inlet of the Chain strand is arranged in the sprocket.
  • the chain conveyor according to the invention offers the advantage that with him the operating state with very simple means of its chain strand continuously monitored is and therefore a review of the discard the user is superfluous. Due to the chosen arrangement the one-armed swivel lever is a high one Switch-off mechanism responsiveness for ensures the drive motor of the conveyor.
  • 1 is a pocket wheel Sprocket with teeth 2 and between each two successive pairs of teeth 2 arranged Pockets 3.
  • the chain wheel is used to drive one a lifting chain forming chain strand 4, the horizontal links 5 come to lie in the pockets 3 and whose vertical links 6 in one between the teeth Grip 2 of a pair of teeth arranged.
  • the chain guide 7 has by a lever pivotally mounted about an axis 8 formed guide element 9 on by a spring 10 pressed into a first position shown in Figure 1 becomes. This first position is opposed by one the left end face of a recess 11 pressed Stop 12 defined.
  • the Guide element 9 holds a stylus 13 Switch 14 the supply circuit one to drive the sprocket 1 serving, not shown Motor closed at an interruption point, i.e. the hoist can be used.
  • FIG. 5 An equally simple and therefore inexpensive solution shows Fig. 5.
  • Construction serves to guide the chain strand 4 a guide element 19 provided with a roller 18 is, which has a circumferential groove in which the the longitudinal leg of the guide element 19 Vertical members 6 can immerse.
