Description
Technical field
The utility model belongs to Construction Technology field, is specifically related to the safety guard of a kind of inclined shaft engineering construction.
Background technology
Need arrange during slope construction that Lifting Convey system transports constructor, material and equipment to work plane in inclined shaft.Hoisting System forms primarily of lifting means, boom hoist cable and travelling bogie.Lifting means is by the upper and lower operation in inclined shaft of rope hoisting travelling bogie.To travelling bogie be caused to fall along inclined shaft if the wire cable rupture of Lifting Convey dolly or lifting means break down, directly threaten constructor's life security of personnel and the mining face under mine that travelling bogie carries.At present, when adopting rail travel in slope construction, can effectively prevent rail travel dolly from occurring because of break rope or the lifting means accident that breaks down and fall of boom hoist cable by " a kind of conveying trolley used in inclined shaft falling-proof brake device " of my company's engineering participation.But, when adopting flexible transport (as travelling bogie runs along the concrete surface that lining cutting completes) in slope construction, still lack a kind of safety guard effectively preventing travelling bogie from falling.
Summary of the invention
For effectively preventing flexible transport dolly from falling, the utility model provides a kind of safety guard being exclusively used in flexible transport trolley travelling in inclined shaft engineering construction.
The utility model is realized by following technical proposal: a kind of safety guard of inclined shaft engineering construction, comprise and connect rope sheave 1, support frame 2, driving spring 3, check band assembly pulley 4, catching device 5, catching device chock 6, transmission device 7 and brake wire 8, described connection rope sheave 1 is fixed on support frame 2, transmission device 7 is connected with the driving spring 3 at support frame 2 two ends and catching device chock 6 respectively, catching device chock 6 movable set is in catching device 5, brake wire 8 is through catching device 5, every root brake wire 8 is clamped by the check band assembly pulley 4 at catching device 5 two ends.
Described check band assembly pulley 4 is installed on safety guard both sides; and there are two groups of assembly pulleys every side; brake wire 8, through two groups of assembly pulleys, makes the cable bent of brake wire 8 in two groups of assembly pulley regions minimum, thus guarantees that catching device can timely and effective catch brake wire rope.Meanwhile, brake wire 8 is also the guide rope of flexible transport dolly, ensures that travelling bogie is along braking steel cable linear running.
Described transmission device 7 is made up of balance plate and transmission arm, the middle part of transmission arm is by the support movable supporting be fixed on support frame 2, balance plate two ends are flexibly connected with one end of transmission arm respectively, and the other end of transmission arm is connected with driving spring 3 and catching device chock 6.
Described catching device chock 6 is two.
When adopting flexible transport in slope construction, install safety guard in travelling bogie front end, and respectively arrange a brake wire in safety guard both sides along travelling bogie traffic direction, its two ends are individually fixed in the upper well head of inclined shaft, lower well head.Flexible transport dolly is along when running in inclined shaft; if wire cable rupture or the lifting means of Lifting Convey dolly break down; the catching device being installed on the safety guard of travelling bogie front end just can be arrested in time and lock onto on check band, prevents travelling bogie from falling along inclined shaft.Detailed process is:
Connect rope sheave 1 by boom hoist cable Lifting Convey dolly; under normal running (operation) conditions, boom hoist cable pulls the transmission device 7 of safety guard; under the effect that safety guard and travelling bogie are conducted oneself with dignity; driving spring 3 compresses; transmission arm drives catching device chock 6 to deviate from catching device 5 downwards and is opened, and travelling bogie just normally can run along the movement of brake wire 8 on check band assembly pulley 4.When the disconnected rope of boom hoist cable or lifting means break down lose tractive force time, by the driving spring 3 that compresses because cease to bind just can stretch to free state, thus by transmission arm, catching device chock 6 is upwards pulled up, two catching device chocks 6 of catching device 5 li block brake wire 8, and make travelling bogie out of service, prevent from falling.
The advantage that the utility model possesses and effect: affect arresting in time of catching device because the brake wire be arranged in inclined shaft naturally droops; therefore the utility model adopts and respectively installs two groups of assembly pulleys in the both sides of safety guard along brake wire; to make the steel cable sag between two groups of assembly pulleys of every root brake wire minimum, thus ensure that the catching device embracing rope device can effective catch brake wire rope.The utility model can guarantee that flexible transport dolly makes travelling bogie stop by catching device catch brake wire rope after losing tractive force, prevents it from falling along inclined shaft, protects on travelling bogie and the life security of underground construction personnel.This safety guard is applicable to be shared in the long slope construction of a boom hoist cable Synchronous lifting travelling bogie by two lifting means.
