The attached drawings are the best embodiments of the auxiliary lifting appliance for lifting the closure segments of the high tower, and the utility model is further described in detail below with reference to the attached drawings.
The auxiliary lifting appliance for lifting the folding section of the high tower comprises a bottom frame 1, two middle boxes 7 are fixed above the bottom frame 1, two sides of each middle box 7 are rotatably provided with a wire roller 4, a wire roller 4 braking device is arranged on each middle box 7, and a lifting rope 5 is wound on each wire roller 4.
One end of the lifting rope 5 is fixed with the wire roller 4, and the other end is a free end which is used for lifting. For convenient connection, the free end of the lifting rope 5 is fixed with a tail end connector 6, and the tail end connector 6 is provided with a threaded hole or a through hole for connecting lifting appliances of different specifications, thereby realizing universality.
After the length of the lifting ropes 5 at the two sides of the bottom plate 1 meets the lifting requirement of the folding section, the wire roller 4 is braked by the braking device, so that the wire roller 4 is prevented from rotating in the lifting process.
For reasonable layout, chassis 1 top intermediate position be fixed with support frame 2, two intermediate boxes 7 symmetry set up in support frame 2 both sides, support frame 2 top be equipped with rings 3. The rings 3 are detachably connected with the support frame 2 through threads or other modes, so that the rings 3 with different specifications can be replaced, and the rings 3 are convenient to overhaul and replace.
The rotating shaft of the wire roller 4 is inserted into the middle box 7, and the braking device is connected with the rotating shaft in a matched mode.
The braking mode of the braking device adopts the following two modes:
first kind: the braking device adopts a pneumatic braking device. The rotating shaft is equivalent to a brake pad, and the rotating shaft and the brake pad are in butt joint through air pressure to generate braking. However, this arrangement requires an external air source, which increases the difficulty of implementation.
Second kind: the rotating shaft of the wire roller 4 is provided with a central control shaft 401 which is coaxially arranged, the circumferential surface of the central control shaft 401 is provided with a plurality of jacks 403, and the jacks 403 are distributed in an annular array around the axis of the central control shaft 401.
The brake device is inserted link 8, is equipped with the through-hole on the intermediate box 7, and inserted link 8 wears to set up inside the through-hole, and the jack 403 is inside inserted to inserted link 8 lower extreme, and the upper end is located intermediate box 7 outside.
Inserting the insert rod 8 into the insertion hole 403, the wire roller 4 cannot rotate; the wire roller 4 can rotate by pulling out the inserting rod 8.
Meanwhile, the wire rollers 4 on two sides of the same middle box 7 can be arranged in a split mode or can be connected together, and the advantage of connecting together is that the lengths of the lifting ropes 5 paid out by the two wire rollers 4 are the same.
The synchronization of the two wire rollers 4 is achieved by coaxially and fixedly connecting the two central control shafts 401 inside the same intermediate box 7.
At this time, the insert rod 8 includes two vertical rods inserted into the insertion holes 403 of the two central control shafts 401, respectively, and a horizontal rod located outside the intermediate box 7.
In order to avoid the lifting process, the horizontal rod falls off, and is located on the top surface of the middle box 7, and meanwhile, a handle is arranged on the horizontal rod, so that the inserting rod 8 can be conveniently inserted and pulled.
The end of the wire roller 4 is fixed with a handle 402, and the wire roller 4 is rotated by the handle 402 to perform paying-off and winding-up operations.
Because the width of the folding section is different, the lifting rope 5 is generally connected with the end faces at two sides of the folding section, in order to adapt to different widths, in the embodiment, a limit regulator 9 is fixed below the underframe 1, the limit regulator 9 positioned at two sides of the underframe 1 is concavely provided with a chute 901 which is penetrated up and down, and a guide pipe 10 which is vertically arranged is arranged in the chute 901 in a sliding manner. The guiding tube 10 slides in the same axial direction as the wire roller 4.
The lifting ropes 5 penetrate through the guide pipes 10, and the distance between the two lifting ropes 5 is controlled by adjusting the positions of the guide pipes 10, so that the folding sections with different widths are adapted.
In order to position the sliding guide tube 10, a plurality of clamping ports 902 are recessed in the top surface of the sliding chute 901, clamping plates 11 can be clamped in the clamping ports, and the guide tube 10 is clamped and limited by the two clamping plates 11.
The embodiments of the present utility model have been described in detail with reference to the drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model.
