Embodiment

Be described in further detail below in conjunction with accompanying drawing:

As shown in Fig. 1-6, the present invention includes saddle seam 1, saddle joist 1-1, supporting frame 2, box type column seam 3 and lifting boom 4.Saddle joist 1-1 adopts channel-section steel, built-in snubber block 1-5, and snubber block 1-5 adopts block rubber, is used for placing the afterbody of main frame 6 at the affixed main frame connecting plate 1-4 in the right side of saddle joist 1-1; The inner vertical welding of the lower end of saddle seam 1 and saddle joist 1-1, stiffening plate 7 is established in both joints.Fixed card 5 is established in box type column seam 3.Fixed card 5 is parts in box type column seam, adopts grooved steel plate, and welds between box type column seam, between supporting frame and fixed card, is bolted.The cross section of saddle seam 1 is opening frame-shaped construction, is inside provided with dampening assembly 1-2, and dampening assembly 1-2 adopts three block rubbers, is screwed on three inner faces of saddle seam, wherein establishes a pair of roll wheel assembly 1-3 near the both sides of opening.The object that roll wheel assembly 1-3 is installed is to be convenient to saddle seam along box type column seam 3 slippage up and down more freely; Supporting frame upper end is provided with a round steel pipe, the A-frame welding on its one end and supporting frame top, and the other end and connecting plate welding, the fixed card in connecting plate and box type column seam is bolted.

Saddle seam 1 is socketed and leans on its deadweight to slide onto in fixed card 5 by block rubber and box type column seam 3, and saddle joist below is dropped on supporting frame.Box type column seam 3 bottoms are highly consistent with supporting frame 2 to fixed card 5 end face height; The present embodiment adopts adjustable lifting boom, can regulate according to actual needs the length of lifting boom.Lifting boom one end is connected to the upper end of saddle seam, and the other end is fixed on speed reducer upper end.Because main frame needs time-based maintenance maintenance, need to be promoted to operation on the bank, pass through rope hoisting by lifting device, in lifting process, for reducing force of rolling friction, wire rope should be as far as possible in vertical state, because machining accuracy causes the center of gravity of every main frame all different, so lifting boom center of gravity is unfixing, need to adjust.Lifting boom one end is connected to the upper end of saddle seam, and the other end is fixed on speed reducer upper end, triangularity,, by regulating the nut location of lifting boom end, drive another two angles to rotate, adjust position, Heave Here.Main frame is fixed on the saddle supporting plate of saddle seam, then glide voluntarily along box type column seam by deadweight, drop on supporting frame, when lifting, lean on lifting device by carrying on wire rope, because main frame (comprising saddle seam) needs maintenance service, regularly need to promote, pool inner water generally can not be put dry, so main frame will freely, can not be fixed up and down, supporting frame and box type column seam need to be fixed, the stability of assurance equipment operation.

As shown in Figure 7, the main frame connecting plate 1-4 that when use, main frame 6 afterbodys is arranged on to saddle joist 1-1 is upper, and head is fixed on saddle seam riser, and in order to increase the stability of main frame, centre distance that can expanded motor head attachment hole, reduces the area of contact with riser.Adjustable lifting boom 4 one end are connected with main frame 6 afterbodys, between saddle joist and supporting frame 2, and be equipped with damping device between saddle seam 1 and cube rod seam 3, therefore adopt this device fixed host computer 6, amplitude is very little, greatly increase the stability of equipment operation, plug-flow effect and the working life of also having improved equipment.
