The specific embodiment
Shown in Fig. 1 to 8; As shown in Figure 1, mine cable car device is made up 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, and the 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, arrest to be provided with laterally on the slideway 11 and arrest stull 10, arrest stull 10 and whenever be provided with one at a distance from 0.5 meter through the slideway suspension bracket 3 that is arranged at support roller suspension bracket 4 outsides; With rope clamping device 6 that steel rope 5 is captiveed joint on be fixedly connected with two-way arresting hook 7, two-way arresting hook 7 is positioned at said top of arresting stull 10, when wire cable rupture, two-way arresting hook 7 falls to arrests slideway 11 and catches on and arrest stull 10.Like Fig. 5, shown in Figure 6, two-way arresting hook 7 comprise the neck of hook of captiveing joint with rope clamping device 6 and with neck of hook lower end bonded assembly coupler body; The said neck of hook is made up of the linkage section that has connecting bore 73 71, bending segment 74, and said coupling end 71 is angle a with the vertical part 75 of bending segment, and angle a is 10 °～20 °; Coupler body is formed by on both sides, bending the suspension hook 76 that is circular arc with bending segment vertical part 75 bonded assembly bar portions 72 and bar portion 72 lower ends.Like Fig. 7, shown in Figure 8, slideway suspension bracket 3 comprises arm 32, and arm 32 upper ends are provided with withholds 31, withholds 31 and is 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.Said rope clamping device 6 is connected with suspension rod 12, and suspension rod 12 is provided with chair lift 13, and said chair lift 13 is provided with shock absorber.
The principle of work of the utility model is: the disconnected rope grip of layout is caught slideway 11 in inclined shaft 1 both sides; Arrest stull 10 for per 0.5 meter fixing one on the slideway; On each support roller beam 2 with slideway suspension bracket 3 ground ways; Fixing two-way arresting hook 7 on each coventional type belleville spring formula fixed rope clip 6, and make it and arrest stull 10 and keep certain safety distance (two-way arresting hook 7 is being arrested 270mm place above the stull 10).Because overhead manned equipment steel rope 5 receives pulling force maximum at head drive wheel place; If when steel rope 5 receives external force effect or tired disconnected the rope, tend to appear at top, inclined gallery, near the main drive wheel; Therefore, disconnected rope catching device shelf (for example: nine ore deposit pedestrian's inclined shaft gradients 30 only need be installed in the tunnel upper semisection
0Tiltedly long 450 meters, only need be installed in the first half and get final product for 240 meters), for preventing that arresting hook 7 is when normally moving; Arrest stull 10 misoperations because of falling to restrict to catch on; At each support roller travel switch 9 (employing normally closed switch) is installed for 8 times, and inserts in the PLC control system, when haulage cable 5 falls to restrict, can in time stop.
When fracture takes place 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 the slideway 11, and catches on and arrest stull 10.When two-way arresting hook 7 is slipped to when arresting in the slideway 11, two-way arresting hook 7 at first rotates to an angle, and behind the buffering downslide impulsive force, arrests stull 10.Behind the wire cable rupture, be 0.5 meter owing to arrest the spacing of stull 10, and two-way arresting hook 7 (being chair lift) spacing it is 9.5 meters; The spacing that is to say two-way arresting hook 7 is the integral multiple of arresting stull 10 spacings, so two-way arresting hook 7 is almost caught simultaneously and arrested stull 10; Finally make the no longer landing of steel rope, chair lift and passenger of fracture, safety arrestment, personnel slide the whereabouts and are no more than 0.5 meter (spacing of arresting stull 10); The chair lift taken of personnel 13 is the spring buffer type in addition, when personnel fall the catching device action, and available buffer downslide impulsive force; Minimizing has been guaranteed the safety of personnel and equipment to personnel's injury, and Fig. 3, Fig. 4 have shown the running state of downlink side, upstream side behind the wire cable rupture respectively; With the downlink side is example, behind disconnected rope, and the downward landing of chair lift passenger and steel rope; The two-way 7 drop action times of arresting hook are through being calculated as 0.252s, through mechanical analysis, when weight ground clearance during less than 1.248 meters; When the two-way arresting hook 7 in disconnected rope back was arrested stull 10, weight landed, and gravity is not participated in the main rope sliding force; This moment, steel rope had only rope gravity, chair lift and personnel to act on the two-way arresting hook 7 from the downslide component of gravity, and any side steel rope component maxim that glided is: 30007.6N is drawn by experiment; Maximum pull was 7.27KN when rope clamping device slided 7 distortion of two-way arresting hook, therefore when disconnected rope takes place when as long as 5 fixing two-way arresting hooks work, 450 meters inclined gallery passengers are braked are not glided; And 25 two-way arresting hooks that are installed in the 240 meters sections in top, inclined gallery enough can make passenger safety take off danger, thereby the safety of realization personnel and equipment has been guaranteed the safe operation of main equipment.
When weight landing distance when disconnected rope back arresting hook is arrested stull during greater than 1.248 meters; Weight gravity is participated in the main rope sliding force, and any side main rope sliding force is through being calculated as 51567.6N, at this moment; The arresting hook that needs to participate in is 7.09; Get 8, just need 8 to arrest the situation that stull participates in just making 450 meters steel ropes sit the people entirely in one-sided 47 chair lift and glide, and 25 two-way arresting hooks that are installed in the 240 meters sections in top, inclined gallery can make passenger escape danger.
In the utility model, arrest slideway and adopt 1 inch thick walled steel tube, also prevent the outer beat of chair lift during equipment operation and fall rope.Testing the built on stilts disconnected rope of the people's cable car trap setting of taking advantage of of proof wide-angle through disconnected rope, is feasible, failure-free, safe, has excellent popularization property and practicality.
