Definitions
- the invention relates to a bottom block, especially for cables, with side arranged, rotatably mounted rope pulleys and one around a vertical axis rotatably mounted load hook, which has at least one thrust bearing on one Supported connecting element and via the connecting element with the rope pulleys is connected, which are mounted on the side of the connecting element.
- Document DE-A-32 20 253 discloses a bottom block which corresponds to the preamble of independent claim 1.
- the thrust bearing in one downwardly open recess of the connecting element arranged and axially is secured. This will significantly reduce the height of the bottom block achieved with high load capacity with tensile loads.
- the compactly trained Connection element also allows the number of individual parts to increase significantly reduce, thereby reducing the assembly effort during assembly the bottom block is achieved.
- the upper end of the load hook shaft is in the shape of the Recess complementary, so that it is positively in the recess can be used.
- the axial securing which has a high tensile load on the load hook enables, is carried out in a simple manner by means of cylinder pins which in the in the area of horizontal tangential grooves formed at the upper end of the load hook shaft intervention.
- the cylinder pins are only on in this embodiment Shear stresses, making the bottom block highly resilient.
- Connecting element is integrally formed.
- connection element the inner halves of the covers of the rope pulleys attached to the Connection element are integrally formed.
- the one-piece connecting element is advantageously formed from one for assembly Middle part for the recess and molded on both sides, each in the middle plane halves, the outer circumference forming hoods that protect the Ensure rope pulleys. Furthermore, the connecting element of the rope pulley axis also molded, central pins for one bearing each.
- FIG. 1 shows a partial section of the bottom block in front view.
- the bottom block has a solid one-piece connecting element 1. This is provided on both sides with a pin 2 on which the also laterally arranged pulleys 3 are supported via bearings 4.
- the camp 4 are stop surfaces formed by the connecting element 1 and additionally secured in their axial position by retaining rings 5.
- the inner half of the Cover 6 is - as shown in FIG. 1 - molded onto the connecting element 1.
- the Cover is closed by an outer half 7, for example, by a screw 8 is fastened to the connecting element 1.
- the correct location of the Cover 6 is achieved in that each cam of the cover 6 by one corresponding recess on the connecting element 1 non-positively or positively be included.
- the connecting element 1 according to FIG. 1 has one on the lower side recess 9 open at the bottom approximately in the form of a cylindrical opening, in which the upper end of the load hook 10 via a thrust bearing with a corresponding outer diameter is positively inserted.
- the thrust bearing from a ball socket 11, the balls 12 and the Ball cage 13 formed. 3 and 4, the ball socket 11 can be seen more precisely; so 3 shows a longitudinal section through the ball socket 11.
- FIG. 4 which shows a cross section along the section line A-A in FIG. 3, is the ball socket 11 provided on both sides with a horizontal tangential groove 14.
- the cylinder pins 15 are only claimed for shear in the exemplary embodiment, whereby a strong connection between the connecting element 1 and the Load hook 10 is made.
- the cylinder pins 15 can additionally by serrated rings 16 are secured in position in the bores 17.
- the one-piece connecting element 1 is thus advantageously formed from one Middle part for the recess 9 and molded on both sides, each in the Half-level, the outer circumference forming covers 6 for protection the rope pulleys 3. Furthermore, the connecting element 1 is formed from on the Rope roller axis formed, central pin 2 for sliding one each Camp 4.
- the load hook should expediently on its back part at the proposed embodiment have recessed grips that hold the Ensure the operator's fingers.
