The specific embodiment
According to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, specific embodiments of the present utility model is described in detail.
This pulley frame mechanism is comprised of outside frame 4, head sheave 5 and locking mechanism 3, and wherein catch gear 3 is comprised of adapter plate 301, spring 302, rotary gear axis 303, quadrant gear 304, locating dowel pin 305, strut bar 306, strut bar turning cylinder 307.It is characterized in that: outside frame 4 is enclosed within guide rail bracket 1 outside, head sheave 5 is arranged on the both sides on outside frame 4 tops, facilitate the mounting or dismounting of guide rail bracket 1, locking mechanism 3 is arranged on outside frame 4, adapter plate 301 is contained in the inner side of outside frame 4, quadrant gear 304 is arranged on adapter plate 301 by rotary gear axis 303, the one end that has connected spring 302 below quadrant gear 304, the other end of spring 302 is arranged on adapter plate 301, quadrant gear 304 can be meshed with tooth bar 2, above quadrant gear 304, by strut bar turning cylinder 307, strut bar 306 is arranged on adapter plate 301, locating dowel pin 305 can make strut bar 306 be fixed on a position or b position.
Because the scantling of structure of pulley frame mechanism outside frame 4 and head sheave 5 is greater than guide rail bracket 1, so when adding or remove the standard knot of guide rail bracket 1, pulley frame mechanism does not need to remove, and only need to move up and down.
When needing the standard knot of the guide rail bracket 1 of installation elevator to increase the height of guide rail bracket 1, first the standard knot of guide rail bracket 1 is increased to required height at top, and then the jacking of pulley frame mechanism is arrived to top, when top lift is removed, by the fixing pulley frame mechanism of catch gear 3, at this moment strut bar 306 is fixed (as Fig. 2) in a position.When top lift promotion pulley frame moves up, quadrant gear 304 rotates, quadrant gear 304 is separated with tooth bar 2, and spring 302 is in compressive state, when top lift is removed, pulley frame mechanism moves down, quadrant gear 304 rotation of meshing and make progress with tooth bar 2 under the 302 power effects of spring bullet, quadrant gear 304 can not rotate after turning to the position contacting with strut bar 306, and quadrant gear 304 is stuck with tooth bar 2, now catch gear 3 lockings, pulley frame can not continue to move down.
In the time need to dismantling the standard knot of guide rail bracket 1 of building hoist, make strut bar 306 fix (as Fig. 4) in b position.Pulley frame mechanism moves down, and quadrant gear 304 upwards rotates, and quadrant gear 304 is separated with tooth bar 2, and due to not effect of strut bar 306, pulley frame mechanism can be moved down into desired position.
Embodiment to pulley frame integral body further illustrates (as Fig. 5): available cage 6 is as the lifting body of pulley frame, when increasing the standard knot of guide rail bracket 1, counterweight 8 can be hung on guide rail bracket 1, now steel rope 7 is in relaxation state, after guide rail bracket 1 has highly increased, cage 6 promotes pulley frame upward movement, and pulley frame rises to after new height, and cage 6 moves down rear pulley frame meeting auto lock; Then need to increase the length of steel rope 7, counterweight 8 is taken off and is suspended on steel rope 7 from guide rail bracket 1, pulley frame can normally be used (as Fig. 6).Dismounting during guide rail bracket, is extracted locating dowel pin 305, and strut bar 306 is fixed on to b position, and cage 6 is held pulley frame and moved down and put down.
In addition, pulley frame lifting body that also can design specialized.
