Definitions

  • the invention relates to a support frame of a hoist, in particular a cable, which consists of at least two end plates, which are detachably connected to each other via at least two longitudinal members and spaced from each other.
  • Hoists in particular electric winches, described, which are modularly constructed from the modules electrical, motor, gear, cable drum, suspension and support frame.
  • the individual assemblies are releasably assembled to allow a variety of combinations.
  • On the support frame the main components of the hoist are attached, in particular, the cable drum is mounted there.
  • the support frame consists of at least two end plates, which are arranged at a distance parallel to each other and connected to each other via longitudinal members. Per face plate at least three screw connections are provided for connecting the side members thereto.
  • the German patent application DE 196 02 927 A1 itself relates to a support frame for winches, which is characterized by a reduced installation effort and a lower To distinguish the weight.
  • the support frame consists essentially of the two end plates, which are connected to each other only via an upper and a lower U-shaped side member and a parallel thereto with the axis of rotation of the cable drum falling tension element.
  • the tension element is made of solid material, at the opposite ends to form a shoulder threaded rod sections are arranged. On one side, the tension element is screwed with its threaded rod portion in a centrally arranged in a face plate internal thread and is located with its annular shoulder on a disk on the flat inside of the face plate.
  • a through hole is provided centrally, which is formed in stages to form an annular contact surface for receiving the shoulder of the tube at the beginning of the threaded rod portion.
  • the threaded rod portion is guided through the through hole and clamped from the outside via a threaded nut with the outside of the face plate.
  • the two U-shaped side members are inserted into suitable recesses in the inner sides of the end plates and are held there by the tension force established by the traction means between the end plates.
  • the connecting elements between the end plates are formed as profiles with a circular or tubular cross section, the ends of which protrude into corresponding bores or correspondingly machined contact surfaces in the mutually facing surfaces of the end elements.
  • An attachment is then via a screw that clamp the profiles in the longitudinal direction with the end plates.
  • These joints between the profiles and the end plates can transmit both axial forces in the direction of the longitudinal axis of the connecting elements or the cable drum and so-called corner moments. Under corner moments are understood here moments that arise, for example, by a distortion of the support frame at the joints between face plates and fasteners.
  • corner moments are understood here moments that arise, for example, by a distortion of the support frame at the joints between face plates and fasteners.
  • the exact distance and the parallelism between the two end plates is produced within the desired tolerances over the length of the profiles.
  • the dimensional stability of the connection at a moment load of the support frame is dependent on the size of the annular end faces, since for reasons of ease of mounting between the inner surface of the through hole in the face plate and the outer diameter of the profiles at least a small gap must be present.
  • end plates components of the hoist can also be housing parts that fulfill various functions of the hoist. For example, these serve for fastening the lifting drive, for storing the cable drum, for mounting trusses for parts of the cable shearing, for receiving the electrical equipment, for foot mounting the hoist or for attaching suspension parts.
  • the invention is based on the object to provide a support frame of a hoist, in particular a cable, which is characterized by a structurally simple design.
  • a structurally simple construction is achieved in that the side members are so releasably connected to the end plates that the ends of the longitudinal members seen in the direction of the longitudinal axis are pressed transversely to the longitudinal support against a contact surface of the end plates. This minimizes the manufacturing effort, since only the contact surfaces for the side members must be generated on the end elements. A preparation of the contact surfaces for the usual in the prior art Axialverschraubung deleted.
  • the desired axis parallelism of contact surface and side members can be achieved particularly easily by appropriate machining of the contact surface regardless of the squareness of the frontal contact surface between the longitudinal member and end plates relative to the longitudinal axis of the longitudinal member.
  • a front-side contact between the side member and end plates is not necessary, but can be done.
  • the longitudinal members are thus each connected non-positively with the end plates.
  • the connecting element is a stud.
  • the stud is a threaded pin with a cup point.
  • bores are arranged in the mutually facing inner surfaces of the end plates, in which the ends of the longitudinal members are inserted.
  • the insertion length of the ends of the longitudinal beams in the holes is greater than the diameter of the ends of the longitudinal members. Due to this greater length of the contact surface against the axial clamping usual in the prior art, a greater dimensional stability is achieved with corner moment load.
  • the required cost of materials and thus the manufacturing costs of the longitudinal members between the face plates are primarily determined by the required moment of inertia from the moment load on the support frame by the cable, the load swinging, Auf einsautechniken or unforeseen shocks to these elements during transport or other improper use.
  • the radial connection minimizes the corner moment load.
  • the holes for the ends of the side members simple lock holes with cylindrical cross section, which are thus particularly easy to produce.
  • These blind holes are characterized by a low manufacturing costs, since an exciting production in only one setup is possible.
  • the stud is screwed into a threaded bore, whose longitudinal axis is aligned transversely to the longitudinal axis of the longitudinal members and the threaded bore is arranged in a bore limiting region of the end plates.
  • the end plates are rectangular and in the corner regions in each case a bore is arranged. These holes are concentric with the center of the cable drum and each offset by 90 ° to each other. Although preferably only two side members are needed to form the support frame, four holes are provided here. Thus, the longitudinal beams in coordination with the planned cable drain, i. without hindering this, be arranged on the end plates. Also, these holes can be used to attach other attachments of the hoist.
  • the longitudinal members are formed as round tubes and are in one piece.
  • the thin-walled round tubes are characterized by a favorable ratio between material costs and moment of inertia.
  • a cable drum is mounted at both ends at this support frame between the end plates, whose axis of rotation is aligned parallel to the longitudinal axis of the side members.
  • FIG. 1 shows a perspective view of a cable pull 1 according to the invention of a lifting device which is driven by an electric motor 2.
  • the electric motor 2 is flanged to a gear 3, which is laterally and externally attached to a support frame 4 of the cable 1.
  • the cuboid support frame 4 consists essentially of two end plates 5a, 5b, which are connected to each other via two longitudinal members 6.
  • the two rectangular end plates 5a, 5b are spaced apart by the longitudinal members 6, with their inner surfaces 5c facing each other and aligned parallel to each other.
  • the longitudinal members 6 are formed as tubes and it is per support frame 4 only two side members 6 are provided, which in opposite corners of the end plates 5a, 5b are arranged.
  • the longitudinal members 6 are each inserted with their opposite ends 6a in holes 8 of the end plates 5a, 5b and held via a Radialverschraubung with a stud 9.
  • the holes 8 are located in the corner regions of the inner surfaces 5c of the end plates 5a, 5b and are designed as paragraph-free Sacklockbohronne.
  • a cable drum 7 of the cable 1 is mounted between and on the end plates 5a, 5b.
  • the axis of rotation D of the cable drum 7 in this case runs parallel to the longitudinal extent L of the side members 6.
  • the end plates 5a, 5b are also housing parts that fulfill various functions of the lifting device and carry, for example, the electric drive 2, are used for storage of the cable drum 7, are used for the cultivation of trusses for parts of the cable shearing, take on the electrical equipment, serve as lunarbefest Trent the lifting device or take up chassis parts of the lifting device.
  • FIG. 2 shows a detailed view of the side members 6 connected to the end plates 5a, 5b
  • the embodiment of the connection between the ends 6a of the side members 6 and the end plates 5a, 5b is explained in more detail.
  • bores 8 for the longitudinal members 6 are arranged in at least two opposite corner regions per end plate 5a, 5b, starting from the inner surfaces 5c.
  • the longitudinal axis L of the holes 8 extends in the assembled state of the support frame 4 and the entire cable 1 parallel to the rotation axis D of the cable drum 7.
  • the holes 8 are each formed as stepless blind holes with a cylindrical inner peripheral surface 8a.
  • annular abutment surface 8b is formed adjacent to the inner circumferential surface 8a thereof.
  • the shape of the bottom of each bore 8 depends on the type of drilling tool used to make the blind hole.
  • the bore 8 has a depth t and a diameter a.
  • the longitudinal carrier 6 designed as a round tube has an outer diameter d which is slightly smaller than The inner diameter a of the bore 8.
  • the insertion length e of the ends 6a of the longitudinal members 6 corresponds to the depth t of the bore 8.
  • the end 6a of the longitudinal members 6 with its annular planar end face 6c on the annular abutment surface 8b at the bottom of the bore 8.
  • the side members 6 are held in the bores 8 via a radial screw connection, which takes place via at least one stud bolt 9 in each case.
  • the preferably used stud bolt 9 is a threaded pin according to DIN 916 with a circular hardened annular cutting edge 9a at one end and a hexagon socket 9b or other pads for a tool at the other end.
  • the stud bolt 9 is screwed for fastening the longitudinal member 6 in the bore 8 in a threaded bore 10 which is arranged in a bore 8 surrounding part of the end plates 5a, 5b and thus the wall of the bore 8.
  • the stud 9 is screwed so deep into the threaded hole 10, that the annular cutting edge 9a cuts into the outer peripheral surface 6b of the end 6a of the longitudinal member 6.
  • the resulting positive connection between the stud bolt 9 and the longitudinal member 6 increases the strength of the connection between the two longitudinal members 6 and the two end plates 5a, 5b.
  • the stud 9 is aligned with its longitudinal axis E at right angles to the longitudinal axis D of the longitudinal member 6 corresponding to the desired Radialverschraubung.
  • the dimensions and tightening torques of the stud 9 are within wide limits selectable and coordinated so that the expected moments and forces in the support frame 4 and thus in the connections between the bore 8, stud 9 and the side member 6 can be received or transmitted with sufficient security ,
  • a circumferential groove 11 is provided in that in the outer peripheral surface of the longitudinal member 6, a circumferential groove 11 is provided.
  • This aligned transversely to the longitudinal axis L of the longitudinal member 6 groove 11 is arranged approximately in the direction of the longitudinal axis L in the middle of Einsteckin e of the end 6a of the longitudinal member 6 and has a width which corresponds approximately to the width of the annular cutting edge 9a of the stud 9.
  • the fact that now the ring cutting edge 9a of the stud 9 can also dip into the groove 11 when screwing, the strength of the connection is further increased.
  • the depth of the groove 11 is made as small as possible, but large enough to achieve the desired tear resistance.
  • the correct axial position of the longitudinal member 6 in the bore 8 is achieved in that either the depth t of the bore 8 coincides with the desired insertion length L of the longitudinal member 6 or optionally also the circumferential groove 11 on the circumference of the longitudinal member 6 with the stud 9 to cover to be brought.
  • the insertion length e of the ends 6a of the longitudinal members 6 in the respective bores 8 of the end plates 5a, 5b is chosen so large that the support frame 4 already reaches sufficient stability with only two diagonally opposite longitudinal member 6.
  • Comparable previous constructions of support frame 4 in contrast, have at least three side members 6.
