Abstract
A cage falling preventing device of a steel wire rope type lift is characterized in that a left inward-inclined dovetail plate and a right inward-inclined dovetail plate are located in a braking base plate, a wedge-shaped sliding block and a semi-circular tubular brake shoe are arranged on the inner side of each dovetail plate, a traction frame is arranged on the lower sides of the dovetail plates, a fixed pulley and a traction line are arranged on the upper side of each dovetail plate, each traction line is connected with the corresponding sliding block and the traction frame, a supporting shaft notch is formed in the position, between the brake shoes, of the braking base plate, a supporting shaft is arranged in the notch, the inner end of the supporting shaft is connected with the traction frame, a spring and a movable ring sleeve are arranged on the outer section of the supporting shaft, a supporting base is arranged at the lower end of the movable ring sleeve, and an adjustable bolt is arranged at the upper end of the spring. The cage falling preventing device of the steel wire rope type lift solves the problem that an instant braking type cage falling preventing device easily enables a guide post frame and a guide post to be damaged and deformed, so that accidents occur, and the cage falling preventing device is very suitable for being matched with the pull rope type lift for use.
Description
Technical field
The present invention relates to Architectural Equipment safety guard-safeguard field, specifically a kind of mechanical device for preventing that steel wire rope type construction elevator cage from falling.
Background technology
The cage falling-proof utensil of current steel wire rope type building construction hoist, be all adopt instantaneous formula structure, the instantaneous time falling at cage by cage stop on guide rail.Its shortcoming is, the application force of instantaneous braking is too large, easily makes guide rail bracket, the impaired distortion of guide rail, and accident even meets accident.
Summary of the invention
The present invention is for solving instantaneous brake type cage falling-proof device, and application force is too large, and the problem that easily makes guide rail bracket, the impaired distortion of guide rail have an accident has designed a kind of progressive cage falling-proof dropping control device.
Technical scheme of the present invention is, a kind of guide rope hoist cage falling-proof device, its special character is, the two intilted coattail boards in upper end in left and right are equipped with at middle part in plane braking seat board the inside, identical wedge block is equipped with in the inner side of coattail board, the vertical brake shoe of semicircle tubulose of indent is equipped with in the inner side of wedge block, on the inwall of brake shoe, leave many enclose to groove; The downside of coattail board is equipped with drawbar frame, the upside of left and right coattail board is equipped with respectively left and right fixed pulley, and draught line is housed on fixed pulley, and one end of draught line is connected with the upper end of wedge block, the other end is fixed on drawbar frame, and the downside of drawbar frame and the upside of fixed pulley are all equipped with track adjusting wheel; On braking seat board between the brake shoe of left and right, have vertical pivot shaft Tiaokou, the pivot shaft vertical with braking seat board face is housed in pivot shaft Tiaokou, the inner end of pivot shaft connects with drawbar frame, outer section is stretched out the outside of braking seat board, and the spring put and the movable ring set of underlying be housed, bearing is equipped with in the lower end of movable ring set, and adjusting bolt is equipped with in the upper end of spring.
During use, first bearing is fixed on cage; Left and right brake shoe is encircled to the periphery at hoister guide rail, and track adjusting wheel is depended on guide rail; By adjusting bolt, spring, adjust the length of draught line, guarantee that the gap between brake shoe and guide rail is suitable; Also make the vertex of pivot shaft pivot shaft Tiaokou on braking seat board.During cage lifting, braking seat board, coattail board, wedge block, brake shoe etc. is accompanied by and slides up and down simultaneously, the cage weightless whereabouts suddenly if gig is in operation, be fixed on the bearing on cage, movable ring set can drive pivot shaft, drawbar frame to glide along pivot shaft Tiaokou moment, drop-down draught line pulls wedge block upwards to squeeze along inclination coattail board by fixed pulley, force the left and right brake shoe direction guiding rail of wedge block inner side to be pressed close to, hold gradually guide rail tightly and stop falling.
Technique effect of the present invention is, adopts technique scheme, can realize a kind of initial braking force adjustable, and braking force increases gradually, the cage of the steel rope material elevator of the progressive buffer-type braking protective device that falls.
Accompanying drawing explanation
Fig. 1 is structural front view of the present invention, and the accompanying drawing that makes an abstract.
Fig. 2 is sectional view of the present invention.
In the drawings, 1 drawbar frame, 2 draught lines, 3 pivot shaft Tiaokous, 4 pivot shafts, 5 fixed pulleys, 6 braking seat boards, 7 brake shoes, 8 wedge blocks, 9 coattail boards, 10 track adjusting wheels, 11 guide rails, 12 bearings, 13 movable ring sets, 14 springs, 15 adjusting bolts.
The specific embodiment:
Below in conjunction with accompanying drawing and example, the present invention is further described.
As shown in the figure, the two intilted coattail boards 9 in upper end in left and right are equipped with at middle part in plane braking seat board 6 the insides, identical wedge block 8 is equipped with in the inner side of coattail board 9, and the vertical brake shoe 7 of semicircle tubulose of indent is equipped with in the inner side of wedge block 8, on the inwall of brake shoe 7, leave many enclose to groove; The downside of coattail board 9 is equipped with drawbar frame 1, the upside of left and right coattail board 9 is equipped with respectively left and right fixed pulley 5, draught line 2 is housed on fixed pulley 5, one end of draught line 2 is connected with the upper end of wedge block 8, the other end is fixed on drawbar frame 1, and the upside of the downside of drawbar frame 1 and fixed pulley 5 is all equipped with track adjusting wheel 10; On braking seat board 6 between left and right brake shoe 7, have vertical pivot shaft Tiaokou 3, the pivot shaft 4 vertical with braking 6 of seat boards is housed in pivot shaft Tiaokou 3, the inner end of pivot shaft 4 connects with drawbar frame 1, outer section is stretched out the outside of braking seat board 6, and the spring 14 put and the movable ring set 13 of underlying be housed, bearing 12 is equipped with in the lower end of movable ring set 13, and adjusting bolt 15 is equipped with in the upper end of spring 14.
During use, first bearing 12 is fixed on cage; Left and right brake shoe 7 is encircled in the periphery of hoister guide rail 11, and upper and lower track adjusting wheel 10 is all depended on guide rail 11; By adjusting bolt 15, spring 14, adjust the length of draught line 2, guarantee that the gap between brake shoe 7 and guide rail 11 is suitable; Also make the vertex of pivot shaft 4 pivot shaft Tiaokou 3 on braking seat board 6.During cage lifting, braking seat board 6, coattail board 9, wedge block 8, brake shoe 7 etc. is accompanied by and slides up and down simultaneously, the cage weightless whereabouts suddenly if gig is in operation, the bearing 12, the movable ring set 13 that are fixed on cage can drive pivot shaft 4, drawbar frame 1 to glide along pivot shaft Tiaokou 3 moment, drop-down draught line 2 pulls wedge block 8 upwards to squeeze along inclination coattail board 9 by fixed pulley 5, force left and right brake shoe 7 direction guiding rails 11 of wedge block 8 inner sides to be pressed close to, hold gradually guide rail 11 tightly and stop falling.
