Abstract
The utility model relates to a lifting compensation system of a steel wire rope amplitude change portal crane. The lifting compensation system is characterized by comprising a lifting system (1) and an amplitude change mechanism (2), wherein the lifting mechanism (1) comprises lifting rollers (3) and lifting steel wire ropes (4); the amplitude change mechanism (2) comprises amplitude change rollers (5) and amplitude change steel wire ropes (6); the fixed ends of the lifting steel wire ropes (4) are reversely wound on the amplitude change rollers (5). The lifting compensation system of the steel wire rope amplitude change portal crane realizes horizontal displacement of a heavy by changing the lengths of the lifting steel wire ropes during amplitude change, so that requirements on mounting and accurate positioning are met, and the working efficiency is improved.
Description
Technical field
The utility model relates to a kind of hoisting compensation system of rope luffing span winch, mainly applies to large-scale heavy industry enterprise and harbour.The technical field that belongs to elevator machinery.
Background technology
Rope luffing system mainly applies on the large-scale high pedestal jib cranes such as shipyard and harbour, and confidential each mechanism speed asked of large-scale heavy industry enterprise's door is slow, can realize and straight line micro-displacement, to meet the needs of assembling etc.Rope luffing door machine is than the door machine of other form, and such as hydraulic luffing, tooth bar luffing, screw rod luffing are compared, laid down cost reduces, maintains simple greatly, more clean environment firendly.
Rope luffing door machine when luffing because the variation of jib angle, the height of lift heavy goods can change, high variable quantity h as shown in accompanying drawing (), this height change produces considerable influence for using, shipyard door machine particularly, requirement for coordinate is very high, does not allow to occur the variation of lifting altitude.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, a kind of hoisting compensation system of rope luffing door machine is provided, the horizontal displacement of lift heavy while realizing luffing, through verification experimental verification, within the scope of the luffing of 50 meters, can guarantee that the variation of lifting altitude is in 0.2 meter, considerably beyond the demand of heavy industry enterprise installation.
The purpose of this utility model is achieved in that a kind of hoisting compensation system of rope luffing door machine, it comprises lifting mechanism and luffing mechanism, described lifting mechanism comprises hoisting drum and hoist rope, described luffing mechanism comprises amplitude-changing drum and variable-amplitude steel wire rope, and the fixed end reverse-winding of described hoist rope is on amplitude-changing drum.
Compared with prior art, the beneficial effects of the utility model are:
The utility model length of hoist rope when changing luffing has realized the horizontal displacement of lift heavy thing, has guaranteed to install and the accurate needs of location, increases work efficiency.
Accompanying drawing explanation
Fig. 1 is the lifting altitude variation schematic diagram without compensation of luff.
Fig. 2 is the structural representation of the utility model compensation of luff system.
Wherein:
Lifting mechanism 1
Luffing mechanism 2
Hoisting drum 3
Hoist rope 4
Amplitude-changing drum 5
Variable-amplitude steel wire rope 6.
The specific embodiment
Referring to Fig. 1-Fig. 2, the utility model relates to a kind of hoisting compensation system of rope luffing door machine, it comprises lifting mechanism 1 and luffing mechanism 2, described lifting mechanism 1 comprises hoisting drum 3 and hoist rope 4, described luffing mechanism 2 comprises amplitude-changing drum 5 and variable-amplitude steel wire rope 6, by the fixed end reverse-winding of hoist rope 4 on amplitude-changing drum 5, hoisting crane is when luffing, hoist rope 4 can be followed amplitude-changing drum 5 inverse change, when variable-amplitude steel wire rope 6 is packed up, hoist rope 4 is emitted, when variable-amplitude steel wire rope 6 is emitted, hoist rope 4 is packed up, in the time of so just can guaranteeing jib changes in amplitude, lift heavy thing is in sustained height.
