The specific embodiment
As shown in Fig. 1 to 8, as shown in Figure 1, mine cable car device is comprised of support roller beam 2, support roller suspension bracket 4, support roller 8, steel rope 5, rope clamping device 6 and drive wheel and return sheave, mine wide-angle is taken advantage of people's cable car rope broken protector, comprise be arranged at 1 both sides, tunnel arrest slideway 11, arrest slideway 11 and be connected with support roller beam 2 by being arranged at the slideway suspension bracket 3 in support roller suspension bracket 4 outsides, arrest on slideway 11 and be provided with laterally and arrest stull 10, arrest stull 10 and arrange one every 0.5 meter; On the rope clamping device 6 being fixedly connected with steel rope 5, be fixedly connected with two-way arresting hook 7, arrest the top of stull 10 described in two-way arresting hook 7 is positioned at, when wire cable rupture, two-way arresting hook 7 falls to arrests slideway 11 and catches on and arrest stull 10.As shown in Figure 5, Figure 6, two-way arresting hook 7 comprises the neck of hook being fixedly connected with rope clamping device 6 and the coupler body being connected with neck of hook lower end; The described neck of hook forms by bending segment 74 with the linkage section 71 of connecting bore 73, and described coupling end 71 is angle a with bending segment vertical portion 75, and angle a is 10 °～20 °; Coupler body is comprised of to the curved suspension hook 76 that is circular arc on both sides the bar portion 72 being connected with bending segment vertical portion 75 and bar portion 72 lower ends.As shown in Figure 7, Figure 8, slideway suspension bracket 3 comprises arm 32, and arm 32 upper ends are provided with withholds 31, withholds 31 for the channel-section steel of back-off, and arm 32 lower ends are provided with cross bar 33; Withhold 31 and support roller beam 2 be welded to connect, cross bar 33 with arrest slideway 11 and be welded to connect.Support roller 8 belows are provided with travel switch 9.Described rope clamping device 6 is connected with suspension rod 12, and suspension rod 12 is provided with chair lift 13, and described chair lift 13 is provided with shock absorber.
Principle of work of the present invention is: at the disconnected rope grip of inclined shaft 1 both sides layout, catch slideway 11, on slideway, fix one and arrest stull 10 for every 0.5 meter, on each support roller beam 2, use slideway suspension bracket 3 ground ways, on each coventional type belleville spring formula fixed rope clip 6, fix two-way arresting hook 7, and make it and arrest stull 10 and keep certain safety distance (two-way arresting hook 7 is being arrested 270mm place above stull 10).Because preventing steel wire rope of overhead passenger 5 is subject to pulling force maximum at head drive wheel place, if when steel rope 5 is subject to External Force Acting or tired disconnected rope, tend to appear at top, inclined gallery, near main drive wheel, therefore, disconnected rope catching device shelf (for example: nine ore deposit pedestrian's inclined shaft gradients 30 only need be arranged on tunnel upper semisection
0450 meters of plagioclases, only need be arranged on 240 meters of the first halves), for preventing that arresting hook 7 is when normally moving, because falling to restrict to catch on, arrest stull 10 misoperations, at each support roller, travel switch 9(is installed for 8 times and adopts normally closed switch), and access in PLC control system, when falling to restrict, haulage cable 5 can stop in time.
When there is fracture in haulage cable 5, the steel rope of drive wheel both sides is respectively under the effect of steel rope 5, chair lift 13, personnel's gravity etc., the down landing of chair lift 13 and passenger, final two-way arresting hook 7 will be fallen and arrest in slideway 11, and catches on and arrest stull 10.When two-way arresting hook 7 is slipped to, arrest slideway 11 when interior, first two-way arresting hook 7 rotates to an angle, and after buffering downslide impulsive force, arrests stull 10.After wire cable rupture, owing to arresting the spacing of stull 10, it is 0.5 meter, and two-way arresting hook 7(is chair lift) spacing is 9.5 meters, the spacing that is to say two-way arresting hook 7 is the integral multiple of arresting stull 10 spacing, so, two-way arresting hook 7 is almost caught simultaneously and is arrested stull 10, finally make the steel rope of fracture, the no longer landing of chair lift and passenger, safety arrestment, personnel slide whereabouts and are no more than 0.5 meter (spacing of arresting stull 10), the chair lift 13 that personnel take is in addition spring buffer type, when personnel fall catching device action, available buffer downslide impulsive force, the injury of minimizing to personnel, guaranteed the safety of personnel and equipment, Fig. 3, Fig. 4 has shown respectively downlink side after wire cable rupture, the running state of upstream side, take downlink side as example, after disconnected rope, the downward landing of chair lift passenger and steel rope, the two-way 7 drop action times of arresting hook are 0.252s as calculated, through mechanical analysis, when weight ground clearance is less than 1.248 meters, when after disconnected rope, two-way arresting hook 7 is arrested stull 10, weight lands, gravity does not participate in main rope sliding force, now steel rope only has rope gravity, chair lift and personnel act on two-way arresting hook 7 from the downslide component of gravity, any side steel rope component maxim that glided is: 30007.6N, by experiment, drawn, when rope clamping device slides two-way arresting hook 7 distortion, maximum pull is 7.27KN, therefore when there is disconnected rope, needing only 5 fixing two-way arresting hooks works, just can make 450 meters of inclined gallery passenger brakings not glide, and 25 two-way arresting hooks that are arranged on the 240 meters of sections in top, inclined gallery enough can make the de-danger of passenger safety, thereby realize the safety of personnel and equipment, guaranteed the safe operation of main equipment.
When weight landing distance is greater than 1.248 meters, after disconnected rope, arresting hook is arrested stull, weight gravity participates in main rope sliding force, any side main rope sliding force is 51567.6N as calculated, now, needing the arresting hook participating in is 7.09, get 8, namely need 8 to arrest stull and participate in just making 450 meters of steel ropes not glide in the situation that one-sided 47 chair lift are sat people entirely, and 25 two-way arresting hooks that are arranged on the 240 meters of sections in top, inclined gallery can make passenger escape danger.
In the present invention, arrest slideway and adopt 1 inch thick walled steel tube, during equipment operation, also prevent the outer beat of chair lift and fall rope.By disconnected rope, experimental results show that the disconnected rope of wide-angle overhead man-riding cable car trap setting, is feasible, failure-free, safe, has good generalization and practicality.
