Detailed description of the invention
The technical solution of the utility model is further illustrated below in conjunction with the accompanying drawings with embodiment.
Incorporated by reference to shown in Fig. 2 to Fig. 4, a kind of revolving furnace sublance lift cart fall arrest locking device of the present utility model, same as the prior art is, the most also include main body frame 12, be connected at the movable pulley 13 of main body frame 12 upper end, the suspension rod 1 being arranged in main body frame 12 center and track 11, the upper end of suspension rod 1 is connected with movable pulley 13, just repeats no more at this.nullUnlike the prior art，Also include the spring 3 being sheathed on outside suspension rod 1，The top of spring 3 and the contacted inner surfaces of main body frame 12 upper end，Main body frame 12 is respectively provided on two sides with, towards the one side of track 11, the base 10 that is locked，The base that is locked is an inclined-plane towards 10 to the one side of track，From top to bottom gradient increases，Locking sliding block 9 it is additionally provided with respectively at each inclined-plane，Form oblique contract with the inclined-plane of the base 10 that is locked to coordinate，Each locking sliding block 9 is vertical towards the one side of track，And sky leaves gap between track 11，The lower end of each locking sliding block 9 is equipped with linkage，And be connected by bearing pin with one end of linkage，The other end of pair of links mechanism is connected by transverse arm 4，The lower end of spring 3 offsets with the upper surface of transverse arm 4，The lower end of suspension rod 1 passes transverse arm 4，And fixed by the lower surface of locking member with transverse arm 4.
Preferably, described linkage all includes intermediate connecting rod 7 and connecting rod 6, one end of intermediate connecting rod 7 is connected by bearing pin with the lower end of locking sliding block 9, and the other end of intermediate connecting rod 7 is connected by bearing pin with one end of connecting rod 6, and the other end of connecting rod 6 is connected by bearing pin with transverse arm 4.
It is also preferred that the left the centre position of described intermediate connecting rod 7 is also connected with being provided with hold-down support 8, and being connected to one end of hold-down support 8 by bearing pin, the other end of hold-down support 8 is fixed on the lower end of main body frame 12.
It is also preferred that the left be also arranged with pilot sleeve 2 outside spring 3 in described main body frame 12.
It is also preferred that the left described transverse arm 4 includes transverse arm block and a pair connecting pin, connecting pin is connected to the both sides of transverse arm block, and is connected with connecting rod 6, the center of transverse arm block is further opened with perforation, in order to penetrate suspension rod 1.
It is also preferred that the left described locking sliding block 9 is 5mm towards the gap between track 11.
It is also preferred that the left the outside of described pair of links mechanism is all additionally provided with guide plate 5, the lower end of main body frame 12 is fixed in the upper end of guide plate 5, and the lower end of guide plate 5 offers gathering sill, and the connecting rod 6 of linkage moves up and down along gathering sill.
Locking process of the present utility model is as follows, when normal operation, by suspension rod 1, transverse arm 4 is pulled up, spring 3 is compressed simultaneously, and drives the connecting rod 6 on transverse arm 4 upwards, and one end that intermediate connecting rod 7 is attached thereto also up is promoted, under the point action of hold-down support 8, the other end of intermediate connecting rod 7 is then toward declining, locking sliding block 9 is also lowered by therewith, is allowed between track 11 produce a gap, does not affect the normal rise and fall of lift cart；But when after wire cable rupture, spring 3 can eject, under the effect of elastic force, drivening rod mechanism action makes locking sliding block 9 rise, owing to being locked, gap between base 10 and track 11 is changeless, so locking sliding block 9 upwards after it face part directly and will reduce moment with the gap of track 11 until both laminatings, thus utilizing the frictional force between them is lift cart moment to stop tenesmus.
Those of ordinary skill in the art will be appreciated that, above embodiment is intended merely to this utility model is described, and it is not used as to restriction of the present utility model, as long as in spirit of the present utility model, change, the modification of embodiment described above all will be fallen in Claims scope of the present utility model.
