Description
Technical field: the utility model relates to a kind of safety device, particularly a kind of elevator are with leading boots formula safety tongs.
Background technology: leading boots in China's elevator industry is at present two individualities that separate with safety tongs, leads boots and is enclosed within on guide rail, play the guiding role in lifting process, prevents that lift car from rocking in lifting process; Safety tongs is also enclosed within on guide rail and moves together in company with lift car, when the load-bearing wires rope of lift car surprisingly disconnects or to throw off while causing lift car to fall safety tongs and guide rail locked, prevent that lift car from falling, play security insurance effect, the generation of the hardly imaginable serious accident that prevents that life-and-death matter.Due to the safety tongs of prior art scheme with to lead boots are splits, be difficult in force guarantee with one heart, therefore in elevator normal different strength phenomenon in service, occur, increased running resistance, smooth and easy operation to elevator has a negative impact, and the normal performance of the security insurance effect of safety tongs simultaneously also affects adversely.
Utility model content: for above-mentioned the deficiencies in the prior art, the utility model provides a kind of volume little, easy for installation, can guarantee to lead the boots formula of the leading safety tongs of the concentricity of boots and safety tongs well.
For achieving the above object, the technical solution adopted in the utility model is: a kind of boots formula safety tongs of leading, comprises that wedge (01), spring baffle ring (02), locking cone sleeve spring (03), trigger (04), trigger spring (05), screw thread block (06), trigger guide (07), steel ball row (08), flexible axle draw core (09), locking tapered sleeve (10), orienting sleeve (11), gland (12), caliper (13) and locking tapered sleeve finger (14).Caliper (13) is provided with column chamber and the pyramidal cavity along axially open, and wedge (01) draws core (09) to be fixedly connected with flexible axle; Wedge (01) passes and trigger (04) sliding block joint from the slotted hole of trigger (04); Trigger (04) and trigger guide (07), screw thread block (06), locking tapered sleeve (10) sliding block joint; Locking cone sleeve spring (03) one end is connected with locking tapered sleeve (10) contact, and the other end is connected with spring baffle ring (02) contact.Locking tapered sleeve finger (14) is fixedly connected with locking tapered sleeve (10); In the pyramidal cavity of locking tapered sleeve (10) in caliper (13), the male cone (strobilus masculinus) of locking tapered sleeve (10) rolls and is connected with steel ball row (08); Steel ball row (08) rolls and is connected with the inner conical surface of caliper (13), and screw thread block (06) is fixedly connected with trigger guide (07); Trigger guide (07) is fixedly connected with caliper (13); Locking tapered sleeve (10) is connected with guide rail (15) slide-and-guide; Spring baffle ring (02) is fixedly connected with caliper (13); Orienting sleeve (11) is fixed in the column chamber of caliper (13); Gland (12) is fixed on the top of caliper (13); Orienting sleeve (11) is connected with cage guide (15) slide-and-guide; Caliper (13) is connected with cage guide (15) slide-and-guide of lift car (21) by wearing pin (22).
The utility model volume is little, easy for installation, can guarantee well to lead the concentricity of boots and safety tongs, move smooth and easy, security insurance, performance sensitive is reliable; Solved that one of elevator producer anticipation solves and can not worry.
accompanying drawing explanation:fig. 1 is structural representation of the present utility model.

Fig. 3 is the A-A cutaway view of Fig. 1.
The specific embodiment:
As shown in Figure 1-Figure 3: a kind of boots formula safety tongs of leading, comprises that wedge 01, spring baffle ring 02, locking cone sleeve spring 03, trigger 04, trigger spring 05, screw thread block 06, trigger guide 07, steel ball row 08, flexible axle draw core 09, locking tapered sleeve 10, orienting sleeve 11, gland 12, caliper 13 and locking tapered sleeve finger 14.Caliper 13 is provided with column chamber and the pyramidal cavity along axially open, and wedge 01 draws core 09 to be fixedly connected with flexible axle; Wedge 01 passes and trigger 04 sliding block joint from the slotted hole of trigger 04; Trigger 04 and trigger guide 07, screw thread block 06, locking tapered sleeve 10 sliding block joints; Locking cone sleeve spring 03 one end is connected with 10 contacts of locking tapered sleeve, and the other end is connected with 02 contact of spring baffle ring.Locking tapered sleeve finger 14 is fixedly connected with locking tapered sleeve 10; In the pyramidal cavity of locking tapered sleeve 10 in caliper 13, the male cone (strobilus masculinus) of locking tapered sleeve 10 rolls and is connected with steel ball row 08; Steel ball row 08 rolls and is connected with the inner conical surface of caliper 13, and screw thread block 06 is fixedly connected with trigger guide 07; Trigger guide 07 is fixedly connected with caliper 13; Locking tapered sleeve 10 is connected with guide rail 15 slide-and-guides; Spring baffle ring 02 is fixedly connected with caliper 13; Orienting sleeve 11 is fixed in the column chamber of caliper 13; Gland 12 is fixed on the top of caliper 13; Orienting sleeve 11 and cage guide 15 sliding block joints; Caliper 13 is connected with cage guide 15 slide-and-guides of lift car 21 by wearing pin 22.
When the track cable of lift car 21 surprisingly disconnects or throws off, flexible axle draws core 09 to pull on wedge 01 and moves, under wedge 01 ramp effect, promoting trigger 04 moves to left, because trigger 04 moves to left, trigger 04 stops that on locking tapered sleeve 10, bullet effect disappears, cause locking tapered sleeve 10 to be upspring under 03 effect of locking cone sleeve spring, locking tapered sleeve 10 arranges 08 by steel ball causes locking tapered sleeve 10 to be tightened up under caliper 13 inner conical surface effects, locking is on cage guide 15, stop falling of lift car 21, play security insurance effect; Lead the locking of boots formula safety tongs and can only rise at the rear lift car 21 of cage guide 15, can not fall.After elevator maintenance personnel reset wedge 01, pull locking cone cover finger 14 to make to lock tapered sleeve 10 to bottom offset downwards, trigger 04 automatically resets under 05 effect of trigger spring, blocks locking tapered sleeve 10; Due to locking tapered sleeve 10 with respect to caliper (13) to bottom offset, the inner conical surface of caliper 13 is arranged the effect of tightening up of 08 pair of locking tapered sleeve 10 by steel ball and is disappeared, make to lock tapered sleeve 10 and become releasing orientation with guide rail (15) locking state, recovered the normal operating condition of elevator.
