DE1123806B - C-shaped hook for transporting sheet metal rolls or metal wire rings - Google Patents

Description

The invention relates to a C-shaped hook for transporting sheet metal rolls or metal wire rings with one inserted between the upper leg of the C-shaped hook and the suspension bolt Compensation device by means of compression springs and one on the upper leg of the hook and the hanger hinged to the suspension bolt substantially engages the suspension point of the hook Brings vertical of the center of gravity caused by the load with the sheet metal roller and its Deposition is displaced so that the leg of the hook that receives the roll or the like is held horizontally will.

It has already been proposed to provide a balancing device between the upper leg of the C-shaped hook and the suspension bolt, which have compression springs and an am the upper leg of the hook and the hanger hinged to the suspension bolt, the suspension point of the hook brings essentially in the vertical of the center of gravity. This well known facility has however, it has the disadvantage that it does not work "softly"; that is, it is unresponsive to subtle different weight ratios so that it is continuously at working systems has not proven itself in continuous operation.

This disadvantage inherent in the known device is made clear by the proposal according to the invention avoided. The hook according to the invention is characterized in that the spring of the compensating device presses against a joint that connects two links, one of which is the one above the central part of the hook and the other in the joint for the suspension bolt is hinged so that the spring, depending on whether the hook carries a load or not, on the Suspension bolt hinged handlebar exerts a different pressure and the joint and thus the The suspension point moves depending on the load on the hook.

When the hook is not loaded, the spring forces the hanger to move to the middle part of the The hook and consequently the suspension point, i.e. the joint carrying the suspension bolt, to move by acting on one of the handlebars so that the suspension point is almost is brought vertically above the center of gravity of the empty hook. On the other hand, the pen exercises exert a pressure on the upper leg of the hook around the lower joint of the hanger pivots so that between the inclination of the hanger and the pressure of the spring against the upper C-shaped hook

Leg of the C-shaped hook a balance is established, which the lower leg of the Holds hook in a substantially horizontal position.

When the hook picks up a sheet metal roll or the like and carries it, the weight the load of the suspension point shifted to the ends of the legs of the hook. At the same time presses the entrained pair of links the spring together until a new state of equilibrium is reached, the keeps the lower leg essentially horizontal and the suspension point anew essentially perpendicularly above the center of gravity, namely the center of gravity of the Hook and load existing whole.

The resistance of the spring to compression must be chosen so that the lower Leg of the hook both with full load on the hook and with partial load as well as without Load is held horizontally. In the event of a spring break, the hook tilts in the safety direction, i.e. the end of the lower leg is raised and prevents the load from falling.

The drawing shows as an exemplary embodiment a C-shaped hook with the inventive

direction for shifting the suspension point in the load position, the one corresponding to the empty hook Position of the device is indicated by dash-dotted lines.

The C-shaped hook has a lower sight, which takes a sheet metal roll2 on the saddle3, furthermore a middle part 4 and an upper leg 5. The latter is penetrated by one Pin 6, on the one hand and on the other hand of the hook struts 7 of a hanger are articulated, the connects the hook to the joint 8 of the suspension bolt 9. The end of the upper leg 5 carries a spring 10 with an articulated piece 11, which is guided by links 12 and 13 articulated by means of bolts 14 will. The handlebar 12 is articulated in the joint 8 on the suspension bolt 9, and the handlebar 13 is hinged by means of bolts 15 to bearing blocks 16, which are on each side of the hook above its middle Part 4 are attached.

The weight of the sheet metal roll 2 adjusts the struts 7 almost vertically, and the link 12 guided by the link 13 compresses the spring 10, the reaction of which on the end of the upper leg 5 of the hook pivots it around the pin 6 until the saddle 3 of the lower leg 1 occupies a substantially horizontal position. At this moment the point of suspension, ie the joint 8, is essentially perpendicular to the center of gravity of the whole formed by the hook and the load. When the load has been deposited at the desired point, the relaxation of the spring 10 lifts the joint piece 11 into the position 11 ', and the link 12, which has reached the position 12', pushes the joint 8 back into the position 8 '. The resistance to the compression of the spring 10 and its relaxation path are chosen so that the suspension point shifted to 8 'is approximately perpendicular above the center of gravity of the empty hook and the saddle 3 of the leg 1 is in the horizontal, ready to accept a new load . The struts 7 are then inclined, as indicated by T.

PATENT CLAIM: C-shaped hook for conveying sheet metal coils or metal wire rings with a compensating device connected between the upper limb of the C-shaped hook and the suspension bolt, which by means of compression springs and a hanger hinged on the upper limb of the hook and on the suspension bolt essentially into the suspension point of the hook Brings vertical of the center of gravity, which is displaced by the load with the sheet metal roller and its settling, so that the leg of the hook receiving the roller or the like is held horizontally, characterized in that the spring (10) of the compensating device against a joint piece ( 11), which connects two links (12, 13) with each other, one of which (13) above the central part (4) of the hook and the other (12) in the joint (8) for the suspension bolt (9) so is articulated that the spring, depending on whether the hook carries a load or not, on the link (12) hinged to the suspension bolt (9) exerts different pressure and moves the joint (8) and thus the suspension point depending on the load on the hook.
