Description

  • The The invention relates to a combined lifting device for persons and loads, consisting of assembled individual components with a Winch and a fall arrester with Rettungshubeinrichtung (HSG-R) and with a rotatable crane column, one at the top End of the column head angle-adjustable crane arm and a telescopic boom has, in particular for personal security in shafts or the like as well as for the transport of loads without the change of Lifting device.
  • Lifting devices for personal security or for the transport of loads are generally portable lifting devices with a jib crane with a delivery device and with a support means in conjunction with a base member. One in the DE 43 27 919 A1 described lifting device can be stationed at different locations in a supply device to a respective stationary base element with a bearing plate. The slewing crane is portable and composed of assembled individual sections. The lightweight portable crane is designed for a maximum load of 1000 kg. If the jib crane consists of a single section, the load capacity is limited according to the weight and its construction. With a larger number of portable and mountable individual sections, the lifting capacity of the slewing crane can be increased. The problem is thus to design a slewing crane in lightweight construction such that the carrying capacity is as large as possible with a low transport cost of the individual components.
  • The slewing crane after DE 43 27 919 A1 consists of individual portable and mountable sections with a swivel housing with the support rollers arranged thereon, a pull rod and a triangular arm with the telescopic boom, whose underside is designed as a hollow profile. The upper bar of the triangular jib, like the drawbar, consists of parallel angular profiles or hollow sections. The telescopic boom is a square profile into which a second hollow profile can be inserted. A disadvantage is the production and assembly of the telescoping hollow sections, which are usually not available fitting. In addition, only a small weight saving can be achieved by two mating hollow sections. As an additional equipment, the lifting device can receive a belay device with a Rettungshubeinrichtung for persons.
  • In the DE 297 23 710 U1 the lifting device on a mobile support frame with at least three held on a common center footrests. In addition to the crane device for lifting and lowering a load, a personal rescue device is provided, which can be disassembled if necessary. The additional personal rescue device increases the possible use of the lifting device. The crane device and the personal rescue device are arranged at a horizontal distance from each other to ensure trouble-free operation. The transport of persons is not allowed.
  • In the DE 20 2005 015 821 U1 Similarly, a combined lifting device with a tripod for striking and supporting a personal safety device is proposed, which is easy to transport. The use of the lifting device is provided in manhole structures that are entered by persons. Manhole entrances to well chambers, pumping stations, water-bearing shafts and other subterranean structures are usually made by ladders. According to the current safety regulations, ladders longer than 3 m may only be used with fall protection. In sewage shafts must be provided because of the risk of lack of oxygen, carbon monoxide or fermentation gas to a Rettungshubeinrichtung.
  • The The invention aims a combined lifting device in lightweight construction, the easy as well as effortless transportable and both for personal security for secured transport of persons as well as for the transport of loads without the change of the lifting device suitable is.
  • According to the invention Task solved by a lifting device with a rotatable crane column, wherein the angle-adjustable crane arm and the telescopic boom from two different sizes Profiles consists and the individual components by means of a plug connection are mounted on which a fall arrester with Rettungshubeinrichtung (HSG-R) and one for the passenger transport modified winch is arranged. The lifting device with a much smaller profile for the boom allows the Lightweight construction and easier transport and construction.
  • In addition, can the assembly of the individual components of the lifting device by plug connections be simplified, which will be further explained below should.
  • The Invention will now be described with reference to an embodiment with reference closer to the drawings explained. Advantageous embodiments of the invention will become apparent from the Dependent claims. In detail shows
  • 1 an assembly drawing of the lifting device,
  • 2 an overview of the individual components of the lifting device,
  • 3 an item drawing with the boom head of the boom behind 2 .
  • 4 a cross section through the winch drum and
  • 5 a side view of the winch drum after 4 with the flange in a schematic representation.
  • In the 1 Lifting device shown consists essentially of three mountable components with a rotatable crane column 1 and one at the top of the column head 2 pivotally arranged crane arm 3 , which is a telescopic boom 4 having. The individual components are assembled by means of plug connections. The crane column 1 is in a floor plate 5 mounted with a pivot bearing about a vertical axis rotatable in a horizontal pivoting range of 360 °. The crane column 1 is tubular in cross-section and is in a bearing sleeve 6 the bottom plate 5 plugged in. Above the bearing sleeve 6 is located to the leadership of the crane column 1 a centering ring 7 with over-grip, which prevents the ingress of water and dirt.
  • The rotational movement of the crane column 1 becomes with a in the amount of the center ring 7 arranged locking lever 8th locked in one of the bearing sleeve 6 arranged locking disk 9 engages with recesses under the influence of gravity. The locking recesses are arranged in the circumferential direction at a distance of 45 °, so that the rotational movement of the crane column 1 can be locked in corresponding intervals.
  • At the top of the crane column 1 is a bifurcated column head 2 for receiving the angle-adjustable crane arm 3 arranged. By pillar head 2 There are several holes arranged one above the other 11 for receiving a pivot pin 12 with which the crane arm 3 can be staked at different heights. The crane arm 3 is at the designated place with a corresponding hole 11 Mistake. With the pivot pin 12 is the crane arm 3 mounted vertically pivotable. The hole 11 is in the back third of the crane arm 3 arranged so that the greater part is over the center of gravity outstretched. To counteract the shift of weight are two tie rods end 13 with fastening bolts 14 hinged to the crane column 1 are stationary connected. Through the tie rods 13 becomes the crane arm 3 held in the angled position.
  • Adjusting the inclination of the crane arm 3 done with the pivot pin 12 in the pillar head 2 with which the crane arm 3 is staked in different heights. Because the end pivot point of the crane arm 3 with the crane column 1 over the tie rods 13 is firmly connected, this is at different inclination of the crane arm 3 essentially always at the same altitude. This will make the operation of the crane arm 3 arranged winch 15 facilitated. Otherwise, if the pivot point for adjusting the inclination of the crane arm 3 in the column head 2 is located, the altitude of the winch 15 constantly changing.
  • The crane arm 3 according to 2 consists of a commercially available preferably rectangular hollow profile or square profile, the end with a holding plate 16 for the winch 15 and frontally on the opposite end with a top plate 17 partially closed in the lower part of the opening. The headstock 17 is also formed in the lower portion as a stop means with an attachment point for a power-driven hoist. Furthermore, the square profile on the front side of the crane arm 3 above the top plate 17 a bevel 18 with a arranged on the upper inner edge stop bar 19 for the telescopic boom 4 on. The telescopic boom 4 is a sliding square profile. The square profile of the boom 4 has a much smaller dimension than the square profile of the crane arm 3 which results in a significant weight saving. The smaller square profile of the boom 4 is favorable for a change in length because of the boom 4 easy in the square profile of the crane arm 3 can be moved. The boom 4 is thus also easily mountable by means of this connector.
  • For this purpose, the top plate 17 of the crane arm 3 a U-shaped cutout 21 on, the dimensions of the square profile of the boom 4 equivalent. The boom 4 is therefore not directly in the inner wall of the square profile of the crane arm 3 but in the U-shaped cutout 21 guided. A spacer plate 22 is located as a second guide element at the insertion end of the boom 4 , The spacer plate 22 Hold the boom 4 inside at a distance to the square profile of the crane arm 3 , The spacer plate 22 at the insertion end is in the upper half of the opening of the boom 4 arranged overhanging. The supernatant is according to the internal dimensions of the square profile of the crane arm 3 such that the boom 4 easy to move in a small game.
  • Plugging in the jib 4 in the chamfer 18 done by lifting the boom head 25 until with the spacer plate 22 the at the top ren inner edge of the crane arm 3 arranged stop bar 19 is under attack. After that, the boom can 4 lowered and into the square profile of the crane arm 3 be inserted.
  • For staking the insertion length are Absteckbohrungen 26 near the top plate 17 of the crane arm 3 and on the length of the boom 4 provided with a locking pin 27 be staked out. Pulling out the jib 4 is in the outermost position by the stop bar 19 limited so that it can not be pulled out unintentionally. The complete removal of the jib 4 takes place in the reverse order of installation by the jib head 25 is raised.
  • The arrangement of the spacer plate 22 has the additional advantage that the vertical load of the telescopic boom 4 not over the locking pin 27 but over the distance plate 22 is derived. The locking pin 27 is not charged and has only a backup function. The locking pin 27 For this reason, it does not have to be specifically designed as a wearing part. The spacer plate 22 also causes the lateral guidance of the boom 4 in the square of the crane arm 3 ,
  • In the in 3 illustrated boom head 25 , corresponding to the detail A in 2 , are for deflecting the ropes 23 for the winch 15 and fall arrester with rescue lift (HSG-R) 24 two pulleys 28 arranged, with a common, secured against rotation pulley axis 29 are stored. The securing of the cable guide takes place according to 3 with a slotted stop plate 20 for the rope hooks. To cover the pulleys 28 is a doubly bent at right angles, the boom head 25 enclosing cover plate 31 provided, the front with a front plate 30 is closed. The cover plate 31 with the front plate 30 is at a small distance to the pulleys 28 arranged and prevents a rope 23 from the pulley 28 can fall down.
  • In addition, with the cover plate 31 the pulley axle 29 secured. The pulley axle 29 has on both sides of the out of the boom head 25 protruding side a circumferential groove 32 in the sheet thickness of the cover plate 31 on. The cover plate 31 is at the right angles bent sides with a tilted to the axis of the boom 4 extending slanted slot 33 provided in the groove 32 the pulley axle 29 is introduced obliquely from top to bottom. For fixing the cover plate 31 is a safety bolt 34 with a pin safety 35 provided by the cover plate 31 immovable and secured with the boom 4 connected is. Due to the inclined arrangement of the slanted slot 33 can the cover plate 31 can not be moved in this way and the pulley axle 29 is securely fixed. At the same time, the release of the cover plate 31 Easy to plug in and without any screw connection possible. The ropes 23 are then free and can from the pulleys 28 be removed.
  • For lifting and lowering of loads is after 4 a conventional winch 15 with a drivable cylindrical winch drum 36 used. Conventional winches are not suitable for passenger transport, because for winches for transporting persons a cable guide or pressure device and a winch drum 36 with a rope groove 40 is prescribed for the orderly winding of the cable turns. In the outer surface of the winch drum 36 becomes a rope groove for this reason 40 for receiving the rope 23 formed. The winch 15 is driven by a hand crank over a not further shown worm gear and additionally has an automatically incident brake. The worm gear has due to the self-locking property an additional safety function in terms of blocking the direction of movement. This design allows for the transport of persons a sufficiently high level of security. For the transport of persons is the winch 15 further modified so that it meets the safety requirements for hanging people receiving means.
  • To 4 has the winch drum 36 a left pulley 37 and a right flange 38 on. The pulley 37 and the flange 38 are in the embodiment with the winch drum 36 firmly welded. The winch drum 36 is modified to the original right pulley 37 through the flange 38 is replaced. This is indicated by the winch drum 36 a larger groove-free section 39 on, so that the flanged wheel 38 at a greater distance from the right front of the winch drum 36 can be mounted. Furthermore, the flanged wheel 38 a rope passage 41 for the rope 23 on. The rope 23 is thus by the flanged wheel 38 through on the groove-free section 39 the winch drum 36 wound with at least two turns of rope and through the rope hole 43 continued in the direction of the axis.
  • The end of the rope 23 will be with an in 5 indicated rope clamp 42 at the winch drum 36 attached. This takes into account the current safety requirements for suspended equipment. With a winch 15 for passenger transport must be after unwinding the rope 23 at least two turns on the winch drum 36 are located. This is done by the modified winch 15 absolutely guaranteed. In addition, next to the rope winch 15 in a conventional manner, a fall arrester with Rettungshubeinrichtung (HSG-R) 24 arranged for persons. This can be ensured without the change of the lifting device, a transport of loads or people. The proposed combined lifting device also allows the protection of persons in structures with climbing aid in addition to the transport of loads. With the lifting device, a person can include the fall arrester with rescue hoist (HSG-R) 24 be lowered or lifted in shafts or on walls without climbing. Without involvement of the winch 15 or fall arrester with rescue lift (HSG-R) 24 Material transport can also be done with a powered hoist at the attachment point of the head plate 17 respectively.
