Definitions

  • the invention relates to a réellerüttelvorraum for compacting concrete.
  • Internal vibrator devices also referred to as internal vibrators, usually have an elongated vibrating body or vibrating body or vibrating bottle.
  • the vibration body enclosing a vibration generator is at least partially immersed in the concrete and vibrated.
  • the vibrating body may be connected to a protective or operating hose, which is fastened to one end of the vibrating body and via which, for example, the energy supply can take place.
  • Internal vibrators can be designed as a hose vibrator or as a bending wave vibrator.
  • hose vibrators such as out of DE 92 17 854 U1 known
  • an electric motor is housed in the rear end of the vibrating body.
  • the rear end describes here the closer the protective or operating hose end of the vibrating body.
  • bending shaft vibrators only a rotating imbalance is accommodated in the vibrating body, while the drive is effected via a bending shaft driven by an external motor and guided in the operating hose.
  • a vibration generator with pendulum drive or with one or more eccentric weights can be arranged.
  • the vibrating body is usually made of metal, e.g. Steel or light metal, and forms a housing for the vibration generating device.
  • the concrete compaction by means of an internal vibrator is effected by direct contact of the outer surface of the vibrating vibrating body with the fresh concrete. This can lead to shocks of the vibrating body to a formwork or to reinforcing bars, which can lead to imprints in the formwork or damage to the vibrating body or of coated rebar. Furthermore, the movement of the vibrating body in the concrete sludge can lead to abrasive wear of the wall material of the vibrating body. To avoid these problems, the vibrating body may be covered with a plastic layer that is more elastic than steel. Such a vibrator with a vibrating body with plastic or rubber sleeve is from the DE-U-1 724 786 known. In this internal vibrator, a rubber element is vulcanized onto the housing surrounding the vibration generating device and thus firmly or non-detachably connected to the housing.
  • the housing In the event of wear or damage to the rubber element, replacement of the metal housing part serving as the support is thus required.
  • the housing must be opened, which can only be done in a clean environment, at least not on a construction site, otherwise there is a risk of entry of dirt particles, which could significantly reduce the life of the réellerüttelvorraum.
  • the elastic element is made of a particularly wear-resistant material.
  • Black rubber HNBR - hydrogenated acrylonitrile-butadiene rubber
  • HNBR hydrogenated acrylonitrile-butadiene rubber
  • the invention has for its object to provide a psychologyttelvorraum, in which a simple and thus cost-effective replacement of attached to the vibrating body elastic element is possible.
  • an internal vibrator device comprising a vibrating body comprising a tubular housing in which one is arranged the vibration generating means, and an elastic member which is releasably secured to an end face of the tubular housing.
  • the tubular housing forms the essential part of the vibrating body and contains at least the vibration generating device with which vibrations for concrete compaction can be generated in a known manner.
  • the drive motor for the vibration generating device can also be housed in the housing. In one variant, however, it is also possible to drive the vibration generating device by means of a flexible shaft drive provided separately from the vibration body.
  • the elastic element in particular a rubber element, is vulcanized onto the housing or forms a solid, non-detachable coating, the elastic element is releasably secured in the invention réellerüttelvorraum.
  • the elastic element can be mounted on the housing by utilizing its elastic properties.
  • the elastic element may be formed like a cap and completely enclose the end face of the housing.
  • the part of the housing which can cause damage to a formwork in particular, protected.
  • the housing may have a bead over which the elastic element is pushed.
  • the bead can e.g. as a covenant, paragraph, projection o.ä. be educated. Through the bead, a cross-sectional widening of the housing is effected, so that the elastic element, after it has been pushed over the bead, can be securely held on the housing.
  • the bead may be formed annularly circumferentially on the end face of the housing.
  • the bead may have a conical surface serving as an assembly aid for the elastic member.
  • the conical surface forms a circumferential oblique surface through which the elastic element expands when pushed, so is increased in terms of its diameter. After overcoming the conical surface, the elastic element can contract again and be held securely on the housing.
  • the bead may have a radially extending abutment surface for positive retention of the elastic element on the end face of the housing.
  • the elastic element when the elastic element has been pushed over the conical surface, it can be held in its position in the form of a positive fit on the abutment surface located behind the conical surface in the sliding direction become. An unintentional release of the elastic element from the housing is thus prevented, although the element does not enter into a material connection with the housing, as would be the case, for example, in the case of vulcanization or gluing. Rather, the elastic element still remains releasably attached to the housing. To solve the elastic element, if necessary, the positive connection must be canceled.
  • the elastic element may have a conical surface which is associated with the conical surface of the bead in order to facilitate the assembly of the elastic element, such that during a mounting operation of the elastic element and thereby to be carried out, in particular axial, relative movement between the elastic element and the bead, the two conical surfaces slide past each other, whereby the diameter of the elastic element is widened.
  • the two conical surfaces of the bead and of the elastic element are thus pushed over one another, whereby the elastic element is first expanded. Only when overcoming the bead can the elastic element contract again.
  • the elastic member may be a radially extending abutment surface which abuts against the abutment surface of the bead, such that the elastic member is positively held on the bead and thus on the housing.
  • the housing does not need to be opened, so that the replacement process of the subject to a certain wear underlying elastic element is greatly simplified. In particular, it is not necessary to open the housing when replacing the elastic element, so that the risk of contamination inside the housing is avoided.
  • the elastic member may comprise an elastic bead, wherein the conical surface of the elastic member and / or the abutment surface of the elastic member are provided on the elastic bead.
  • the housing can have a bead and, on the other hand, the elastic element can have an (elastic) bead.
  • the elastic bead may e.g. as a covenant, heel, projection, thickening or similar be educated. By passing the two beads together, the desired positive engagement is achieved.
  • the elasticity and thus the resilient properties of the elastic element may be sufficient to reliably hold the elastic element to the housing in a form-fitting manner.
  • an additional spring-elastic element This may be, for example, a vulcanized snap ring, a snap ring inserted into a groove running around in the bead, a spring ring or a worm spring.
  • the spring-elastic element can thus also comprise a metallic spring which, in addition to the elastic material of the elastic element, supports or stabilizes the spring effect.
  • the housing may be a metal housing in the usual way, while the elastic member may be made of a rubber material, for example of HNBR, or of a plastic material.
  • the housing is closed in the area in which the elastic element is attached. As a result, the housing interior is protected against the ingress of dirt, in particular but also the concrete vat or other liquids.
  • the housing has on the end face on which the elastic element is fixed, an opening which is closed by the elastic element attached to the housing.
  • the elastic element serves as part of the housing and closes tightly and reliably the housing end face.
  • the figures show a vibrating body 1, which is part of a mecanical or a retetradeviations, in particular a so-called Schlauchrüttlers.
  • a vibrating body 1 On the vibrating body 1 can - in the FIGS. 1 and 2 above - an unillustrated protective or operating hose are attached, over which an operator holds the vibrating body 1 and immersed in the concrete to be compacted.
  • the vibrating body 1 has a metallic, tubular housing 2, which is composed of two housing parts 2a and 2b.
  • the two housing parts 2a, 2b are screwed together at a mounting point 3.
  • a drive motor (electric motor), also not shown, is provided axially to the oscillation exciter in order to set the imbalance mass in rotating motion.
  • the drive motor is supplied via electrical lines 4 with electrical energy.
  • the power lines 4 are arranged in the interior of the protective and operating hose, not shown, and thus effectively protected against mechanical damage and moisture.
  • an elastic element 5 is arranged on the front side of the housing 2, in particular of the housing part 2a.
  • the elastic element 5 may consist of an elastic plastic or of a rubber material. It is detachably fastened to the housing 2 or its housing part 2a and can thus be separated again from the housing 2. This is particularly necessary when the elastic element 5 is worn after prolonged use and must be replaced.
  • the housing part 2a has a bead 6, which can be produced, for example, in a simple manner by turning.
  • a conical surface 7 and the opposite rear stop surface 8 is provided ( Fig. 3 ).
  • the cap-shaped elastic element 5 also has a bead 9, which is formed on the inside. At the bead 9, a conical surface 10 and a stop surface 11 is formed.
  • the elastic element 5 can be pushed for mounting by means of the conical surfaces 7 and 10 sliding past each other in a very simple manner to the front end of the housing part 2a.
  • the bead 9 of the elastic element 5 expands in such a way that the elastic element 5 can slide over the bead 6 of the housing part 2a.
  • the elastic element 5 is held positively in the end position shown in the figures on the housing part 2a and the housing 2.
  • either the bead 9 must be widened or the elastic element 5 is pulled with a tool from the housing part 2 a. Alternatively, it is also possible to cut the elastic element 5.
  • a worn elastic element 5 can thus be exchanged at the place of use by a suitable tool. It is no longer necessary to perform a repair in a particularly clean environment, since an opening of the vibrating body 1 by separating the two housing parts 2a, 2b is not required. In addition, an exchange of the elastic element 5 is inexpensive to perform, since no other housing parts, such as the front housing part 2 a must be replaced.
