Referring to Fig. 2, the roughly principle of work of hydraulic actuator in the present invention (II) is described.
When elevator stall, being fixed on second, third driving hydraulic actuating cylinder (5) connected on stock (18,19) drives main fork (6) to swing around fork S. A. (17), and then drives the guide wheel (50) of the rolling guide wheel mechanism (I) be made up of brake wheel (3) and antifriction rubber (4) press to three driving surfaces of T-shaped guide rail (1) and clasp with it.
Referring to the exploded drawings of the guide wheel (50) shown in Fig. 3,4, the concrete pie graph of the stall mechanism (III) shown in Fig. 5,6, guide wheel (50) shown in Fig. 7,8 and the assembled relation figure of fork (6,8) supporting guide wheel (50), be described the formation of stall mechanism (III) and principle of work.
Stall mechanism (III) comprises back-plate (9), brake pad (22), brake shoe brake cheek (23), supporting pin (32) and hydraulic wheel cylinder (40).As shown in Figure 3, remove brake wheel (3), the stop mechanism occurring back-plate (9) and be integrated on back-plate (9).As shown in Figure 4, brake wheel (3) has peep hole (21), to facilitate the service condition of inspecting the inner stall mechanism (III) of guide wheel (50).As shown in Figure 5, be the strut member of back-plate (9) and a series of brake shoe brake cheek (23) mounted thereto.As shown in Figure 6, remove back-plate (9), stress the major part illustrating stop mechanism.Brake pad (22), brake shoe brake cheek (23) form neck in similar automobile drum brake from shoe type structure; Brake shoe brake cheek (23) maintains a certain distance with back-plate (9) under the support of brake shoe brake cheek strut member (36,37); Brake shoe brake cheek (23), under the effect of supporting pin (32), supporting pin cover plate (33), spring cotter (34), can rotate around supporting pin (32); Adjustment cam (38) rotates around self under the effect of cam adjustment knob (41), thus drive brake shoe brake cheek (23) to rotate around supporting pin (32), with the gap between adjustable brake brake lining (22) and brake wheel (3), brake shoe brake cheek (23), under the effect of brake shoe hold down spring (28), limit spring seat (29), stop screw (30), keeps parallel with back-plate (9); Brake shoe brake cheek (23) return under the effect of upper and lower pull back spring (24,31) also keeps the rigid contact with braking liquid cylinder pressure (40); Hydraulic actuating cylinder (40), under the effect of braking liquid cylinder pressure tie bolt (42), is fixed on back-plate (9); Slotted brake shoe brake cheek opening frame (25) is filled between two brake shoe brake cheek (23), opening frame (25) and brake shoe clearance adjustment block (26), brake shoe clearance adjust spring (27) combined action, with braking liquid cylinder pressure (40) under return state, the power of two brake shoe brake cheek is distributed to adjust two brake shoe brake cheek opening, two brake shoe brake cheek can well be worked; When elevator stall, brake shoe brake cheek (23) promotes brake pad (22) and opens under the effect of braking liquid cylinder pressure (40), and brake pad (22) contacts also phase mutual friction with stall guide wheel with brake wheel (3).
Referring to Fig. 1, Fig. 7, Fig. 8, the assembly relation of leading boots is described.
Back-plate (9) is fixed together with secondary fork (8) under the effect of back-plate tie bolt (43); Back-plate (9), secondary fork (8), be connected with main fork (6) by bogie (16); Main fork (6), secondary fork (8) by fork S. A. (17) with lead boots pedestal (7) and be connected.
Referring to Fig. 2, the roughly principle of work that the present invention realizes emergency braking is described.
When elevator stall, brake pad (22) and brake wheel 3) contact also phase mutual friction to brake guide wheel, then hydraulic actuating cylinder (5) is driven to drive main fork (6) to swing around fork S. A. (17), and then drive the guide wheel (50) of the rolling guide wheel mechanism (I) be made up of brake wheel (3) and antifriction rubber (4) press to three driving surfaces of T-shaped guide rail (1) and rub with it, can emergency braking be realized.
According to the present embodiment, when elevator normally runs, three guide wheels (50) of rolling guide wheel mechanism (I) are close on three driving surfaces of T-shaped guide rail, lift car movement in the horizontal direction can be limited, reach and reduce the operating vibration of elevator and noise, improve the function of the comfort taken; When elevator fault speed, stall mechanism (III) and hydraulic actuator (II) combined action allow guide wheel (50) stall rubbing with cage guide (1) to provide enough large power, so can enough large friction force be produced, so lift car emergency braking can be made effectively.
Thus, the present invention allows and leads the dual-use function that boots achieve guiding and emergency braking, and lead the needs that boots can run according to elevator, mapping function in time, there will not be again mutual interference.
