Definitions
- the invention relates to a mechanical clamp connection for the end sections of a conveyor belt which can be set up endlessly, in particular in a belt bucket elevator, in which the belt end sections are led out of the plane of the conveyor belt and are non-positively clamped between at least two shaped pieces enclosing the conveyor belt, the shaped pieces being closed by means of at least one on both sides of the conveyor belt they are connected by a screw connection and are held under tension.
- a generic clamping device is described in DE-PS 33 46 802, in which reference is also made to the problem existing with such clamping connections, according to which the pre-tension imparted to the screw connections is reduced over the course of the operating time because the rubber between the shaped pieces of the conveyor belt end sections during the company crawls or gives way. If this condition is not eliminated by retightening the screw connection in good time, there is a risk that if the value falls below a predetermined limit for the pretension of the frictional connection of the clamp connection is reduced and the belt slips out or screw breaks occur, so that the clamp connection no longer holds the conveyor belt and the belt breaks.
- the invention is therefore based on the object of improving a generic clamping device in such a way that early detection of the decrease in the pretensioning force and problem-free re-tensioning of the clamping connection is given.
- the invention is based on the fundamental idea that between the screw head and / or the nut of the supplied associated SSverbi ⁇ disme * and a preloaded compression spring is arranged in the molding. This is associated with the advantage that, due to the prestressed compression spring, a relaxation of the pre-tension mediated by tightening the screws of this screw connection is greatly delayed by the prestressed compression spring largely maintaining the state of tension. This initially results in greater operational reliability of the clamp connection because, firstly, the need for re-tensioning occurs less frequently and because there is still sufficient scope during a predetermined maintenance interval to maintain the pretension above an empirically determined value during the maintenance interval.
- a compression spring can be arranged only on one side of the screw connection, that is to say for example only in the area of the screw head or the screw nut; however, it is also part of the invention to arrange a compression spring between the screw head and the fitting and between the nut and the fitting.
- both screw connections can be equipped with additional springs; However, according to one embodiment of the invention, it may be sufficient to provide only one of the screw connections on each side of the belt ends with additional compression springs.
- These Druckfeder ⁇ are preferably designed as disc springs; alternatively, the use of screw springs of appropriate strength is also possible.
- the invention is particularly advantageously implemented when the shaped pieces in the area of the screw connections equipped with compression springs have recesses for receiving the preloaded compression springs, the height of which corresponds to the dimension of the preloaded spring assembly. If the compression springs lie in these recesses, this has the particular advantage that dust or, for example, debris and trickle material conveyed with the bucket elevator or the associated buckets cannot get between the spring spaces, so that the compression springs are reliable in their function .
- An expedient exemplary embodiment of the invention further provides that the washer of the associated screw part, or the slip-on washer, have a positively projecting shoulder in the recesses of the molded parts, or the sleeve, the extent of which is expediently larger than the predetermined relaxation path in the Recess seated compression spring. In this way, it is prevented that dirt or other particles can enter the interior of the recesses even when the gap is released by the spring release, because the shoulders extending over a corresponding section here ensure a tight closure of the recesses to the outside.
- Fig. 2 shows another embodiment of the clamping connection.
- the two end sections 11, 12 of a conveyor belt 10 to be made endless are guided substantially outward from this plane at right angles to the plane of the conveyor belt 10 and lie against one another with the inclusion of an intermediate piece 13.
- the intermediate piece 13 On the inside of the end sections 11, 12, in the region of the gusset formed by the bent end sections, the intermediate piece 13 has a section 14 which guides the end sections 11, 12 with their associated outer surfaces when they are angled; In the plane of the conveyor belt 10, the section 14 has a further surface which can have a slight curvature, for example in coordination with a drive drum (not shown) for the conveyor belt 10.
- a respective mold 15, 16 On the outside of the Enda 'bitese 11, 12 is a respective mold 15, 16 which faces in their the gradient layer of the conveyor belt 10 area also a the angling of the end portions 11, 12 of the conveyor belt 10 have leading curvature and perpendicular to the running plane of the conveyor belt 10 run straight, taking the end portions 11, 12 of the conveyor belt 10 running in accordance therewith between them.
- the fittings 15, 16 are by means of two adjacent high-strength Schr 'aubrive ⁇ 17 with a screw head 18 and a nut 19 connected to each other, wherein the screw connections 17 are tightened with ent speaking biasing force.
- both screw connections 17 have compression springs 20 between their screw heads 18 and the shaped piece 15, which are also tensioned by tightening the screw connections 17.
- the mutually opposite shaped pieces 15, 16 in the area of the screw connections 17 arranged on the inside to the level of the conveyor belt 10 have a greater thickness than in the area of the outer screw connection, so that the screw heads 18 or screw nuts 19 are arranged in mutually offset planes, with which not only is the accessibility to both screw connections improved, but also the visual recognition of the tension state of the screw connection or the compression springs.
- FIG. 2 Another exemplary embodiment with further variants of the invention is described in FIG. 2, in which the shaped pieces 15, 16 each have a recess 21 for receiving the associated compression springs 20, so that the compression springs 20 when the screw connection is tightened 17 lie in the recesses 21.
- separate sleeves 25 are arranged in the outer screw connection 17 between the shaped pieces 15, 16 and the screw head 18 or the screw nut 19, the recesses 21 arranged in the sleeves now accommodating the compression springs 20.
- Screw head 18 and nut 19 each have a washer 22 on their side assigned to the compression springs 20, against which the compression springs 20 are supported. The diameter of these disks 22 is larger than the inner diameter of the recesses 21, so that the disks 22 and thus screw head 18 or nut 19 cannot enter the recess 21.
- the two screw connections 17 have in the area of their respective lower screw nuts 19 connected to the washers 22 and extending into the respectively arranged recesses 21 of the shaped part 16 or the sleeve 25 shoulders 23, the depth of which is dimensioned greater than the relaxation path of the Compression springs, so that when the disk 22 is detached from the shaped piece 16 or the sleeve 25, a gap is created to make the decreasing pretension visible, but due to the recess 23, which closes off from the environment, no foreign particles in the recess 21 can enter.
