Abstract
The utility model provides an overhead manned overspeed protection device which comprises a fixed frame, a protection plate, an axle pin and a stay cord, wherein the fixed frame is fixedly connected with a towing cord support on a manned car track and hinged with the protection plate, an axle sleeve is arranged on the protection plate, the axle pin and an axle pin strut on the fixed frame are sheathed, one end of the axle pin can be spliced with the axle sleeve, the other end of the axle pin is connected with the stay cord, a passenger pulls the stay cord in needing emergency braking, so as to release the protection plate for emergency braking, thus effectively preventing the occurrence of overspeed driving accidents.
Description
Technical field
The utility model relates to a kind of mining protective device, is specially the safety device on a kind of overhead manned equipment.
Background technology
At present, down-hole, mine overhead manned equipment is used for the manned use in inclined gallery more, and general overhead manned equipment is provided with rope clamping device, and the gait of march in order to the control vehicle frame when overhead manned equipment overload operation or brake failure, very easily causes runaway accident; The rope clamping device long-term use, friction force descends, and during driving, also can cause rope clamping device from slipping, and produces potential safety hazard.
Summary of the invention
The utility model is exactly that a kind of built on stilts people's of taking advantage of overspeed protection rational in infrastructure will be provided.
A kind of built on stilts people's overspeed protection of taking advantage of; It comprises fixed mount, guar plate, pivot pin and stay cord; Fixed mount with take advantage of the tow strap support on people's Car Track to be fixedly connected, be hinged with guar plate on the fixed mount, guar plate is provided with axle sleeve, the pivot pin pole socket on pivot pin and the fixed mount; Pivot pin one end can be pegged graft with axle sleeve, and the other end is connected with stay cord.
The latch ends of described pivot pin is provided with spring, and spring is arranged between pivot pin pole cover contact and the latch.
Described pivot pin pole is connected with fixed mount through set screw.
When the axle sleeve at described guar plate back and pivot pin are pegged graft, guar plate with take advantage of people's Car Track steel rope parallel, when pivot pin was deviate from from axle sleeve, whereabouts, guar plate end was connected with the steel rope contact.
Described guar plate end is provided with arc-shaped notch, and the guar plate recess can be connected with the steel rope contact.
Described stay cord is parallel with steel rope.
The principle of work of the utility model is: during normal condition; Pivot pin is pegged graft with the axle sleeve of guar plate under acting force of the spring, and guar plate is parallel with steel rope, and the rope clamping device of device can normally pass through from steel rope by bus; When abnormal condition such as occurring driving over the speed limit; Spur stay cord immediately and make pivot pin break away from axle sleeve, guar plate then falls and contacts with steel rope, and plays and block the effect that rope clamping device is realized emergency braking.
This practical new beneficial effect is: through this device, improved the safety of overhead manned equipment, actv. has prevented the generation of hypervelocity train operation accident.
Description of drawings
Fig. 1 is the utility model example structure scheme drawing.
The specific embodiment
Like a kind of built on stilts people's overspeed protection of taking advantage of shown in the drawings; It comprises fixed mount 1, guar plate 2, pivot pin 3 and stay cord 4; Fixed mount 1 with take advantage of the tow strap support on people's Car Track to be fixedly connected, be hinged with guar plate 2 on the fixed mount 1, guar plate 2 is provided with axle sleeve 5, pivot pin pole 6 sockets on pivot pin 3 and the fixed mount; Pivot pin 3 one ends can be pegged graft with axle sleeve 5, and the other end is connected with stay cord 4.
The latch ends of described pivot pin 3 is provided with spring 9, and spring 9 is arranged between the cover contact and latch of pivot pin pole 6, and under the spring force effect, latch 3 is connected surely with axle sleeve 5 and leans on.
Described pivot pin pole 6 is connected with fixed mount 1 through set screw.
When the axle sleeve 5 at described guar plate back is pegged graft with pivot pin 3, guar plate 2 with take advantage of people's Car Track steel rope 1 parallel, when pivot pin 3 was deviate from from axle sleeve 5, whereabouts, guar plate end was connected with steel rope 7 contacts.
Described guar plate 2 ends are provided with arc-shaped notch 8, and guar plate recess 8 can be connected with steel rope 7 contacts.
Described stay cord 4 is parallel with steel rope 7; Stay cord 4 is arranged on position on steel rope 7 one lateral deviations; Pulling stay cord 4, then pivot pin 3 in tensiones break away from axle sleeve 5, and guar plate 2 falls to being stuck on the steel rope 7; Thereby to the emergency braking effect of playing of overhead manned equipment, the safety that has improved overhead manned equipment.
