Abstract
The utility model discloses a kind of device lifting large wt pts, include suspension hook and be connected to the heavy burden rope on suspension hook, the bottom of heavy burden rope is connected with fixed pulley, the below of fixed pulley is provided with the movable pulley be connected with the colligation point or hanger that hang thing, fixed pulley and movable pulley are wound with wiring, and the two ends of chain block are connected with the fag end free end of wiring, movable pulley respectively.The utility model is by the setting of assembly pulley, and the pulling force that chain block can be born reduces, and has the features such as safe and reliable, practical, operating efficiency is high, construction cost is low.
Description
Technical field
The utility model relates to hoisting technology field, specifically a kind of device lifting large wt pts.
Background technology
The method that at present conventional adjustment component (equipment) lifts attitude carries out adjustment (see figure 1) for arranging chain block on heavy burden rope, and the hoisting capacity of chain block is generally 0.5-20 tons, for hang thing weight little time comparatively simple and practical.But, when single heavy burden rope is needed to bear 20 tons and above pulling force, conventional chain block hoisting capacity can not meet the demands, the device resource that can meet hoisting capacity requirement is few, and equipment self-weight is large, inconvenient operation, be difficult to realize the adjustment that large wt pts (equipment) lifts attitude, bring a difficult problem to the accurate hoisted in position of large wt pts (equipment).
Utility model content
The technical problems to be solved in the utility model is to provide a kind of device lifting large wt pts, and by the setting of assembly pulley, the pulling force that chain block can be born reduces, and has the features such as safe and reliable, practical, operating efficiency is high, construction cost is low.
The technical solution of the utility model is:
A kind of device lifting large wt pts, include suspension hook, the heavy burden rope be connected on suspension hook, the bottom of described heavy burden rope is connected with fixed pulley, the below of fixed pulley is provided with the movable pulley be connected with the colligation point or hanger that hang thing, described fixed pulley and movable pulley are wound with wiring, and the two ends of chain block are connected with the fag end free end of wiring, movable pulley respectively.
The standby rope of safety is connected with between the fag end free end of described wiring and movable pulley.
Advantage of the present utility model is:
(1), by the setting of assembly pulley, the pulling force that chain block bears can be decreased to F/n(F restricts stressed for bearing a heavy burden, n value arranges according to assembly pulley and wiring winding is determined), adopt the chain block of relatively ting model to complete adjustment work that large wt pts (equipment) lifts attitude, safe and reliable;
(2), be provided with the standby rope of safety, eliminate the potential safety hazard of chain block position, add the safety of lifting.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing large wt pts hanging apparatus.
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
See Fig. 2, a kind of device lifting large wt pts, the heavy burden rope 2 including suspension hook 1 and be connected on suspension hook 1, the bottom of heavy burden rope 2 is connected with fixed pulley 3, the below of fixed pulley 3 is provided with the movable pulley 4 be connected with the colligation point or hanger 8 that hang thing 9, fixed pulley 3 and movable pulley 4 are wound with wiring 5, and the two ends of chain block 6 are connected with the fag end free end of wiring 5, movable pulley 4, and are also connected with the standby rope 7 of safety between the fag end free end of wiring 5 and movable pulley 4 respectively.
Concrete use procedure of the present utility model is as follows:
First, treating hoisting structure chooses suspension centre, the utility model device is being installed; Secondly, after the utility model lifting, hang thing 9 liftoff before, workmen changes fixed pulley 3 and movable pulley 4 spacing by carrying out lift adjustment to chain block 6, completes to hang thing 9 and lift aerial statue and tentatively adjust (close to design and installation attitude), continues lifting after adjustment, when hanging thing 9 and being lifted near design attitude, can change fixed pulley 3 and movable pulley 4 spacing by carrying out lift adjustment to chain block 6, slight adjustment is hung thing 9 and is lifted attitude, realizes the accurate positioning hanging thing 9.
Claims (2)
1. the device of the large wt pts of lifting, include suspension hook, the heavy burden rope be connected on suspension hook, being connected to bear a heavy burden rope bottom and the chain block that hangs between the colligation point of thing or hanger, it is characterized in that: the bottom of described heavy burden rope is connected with fixed pulley, the below of fixed pulley is provided with the movable pulley be connected with the colligation point or hanger that hang thing, described fixed pulley and movable pulley are wound with wiring, and the two ends of described chain block are connected with the fag end free end of wiring, movable pulley respectively.
2. a kind of device lifting large wt pts according to claim 1, is characterized in that: be connected with the standby rope of safety between the fag end free end of described wiring and movable pulley.
