Described work hanging basket trailer coupling is made up of hanging basket rack winch 1, changed course pulley one A3, changed course pulley one B5, drawbar frame 18 and hanging basket steel rope 12, and pulley one A that wherein alters course is for changed course dynamometry pulley, described hanging basket rack winch and changed course pulley one A are positioned at the side path ground through with vertical shaft top, changed course pulley one B is arranged at the fixed mount of described shaft top, drawbar frame is positioned at described vertical shaft, this drawbar frame is connected and fixed by hoist cable 21 and described work hanging basket, the two ends of drawbar frame are respectively provided with an equalizer pulley 10, described hanging basket steel rope is set in the equalizer pulley at described drawbar frame two ends, the steel rope attachment point of described shaft top is fixed in this hanging basket steel rope one end, the hanging basket steel rope other end is fixed on described hanging basket rack winch after being set in described changed course pulley one B and changed course pulley one A,
Described man cage trailer coupling is made up of 17, two, coaxial twin drum winch 2, two groups of planar guide pulleys changed course pulley two A4, two balancing cylinders 7, two changed course pulley two B8, one pair of steel rope catching device and two man cage steel ropes 13, wherein alter course pulley two A for changed course dynamometry pulley, between the oil pocket of two balancing cylinders, is connected with soft connecting pipe 22, described coaxial twin drum winch 2, two groups of planar guide pulleys 17 and two changed course pulley two A4 are positioned at the described side path ground through with vertical shaft top, two balancing cylinders are arranged at the fixed mount of described shaft top, two changed course pulley two B are installed on the piston rod outer end of described balancing cylinder respectively, two card rope slings 20 of one pair of steel rope catching device are fixed on man cage radially symmetrically and are set in the section corresponding with described hanging basket steel rope attachment point and pulley one B that alters course of described hanging basket steel rope respectively, two changed course pulley two B are set in after two man cage steel ropes are connected to two card rope slings of steel rope catching device successively respectively correspondingly, two reels of coaxial twin drum winch are connected in after being set in two changed courses pulley two A and two group of planar guide pulley again, described two groups of planar guide pulleys often group are two, corresponding to a man cage steel rope, on man cage 9, the both sides of radial symmetry are respectively provided with upper and lower two rope guiding holes 19, this rope guiding hole of both sides is set in the section corresponding with hanging basket steel rope attachment point 6 and pulley one B5 that alters course of hanging basket steel rope respectively, the oscilaltion of hanging basket steel rope is carried over, steady ordered with the hanging basket steel rope of both sides for leading when man cage is elevated.
Changed course pulley one A in the present invention and changed course pulley two A is changed course dynamometry pulley; its function one is as hanging basket steel rope, man cage steel rope tractive guiding; two is have sensor force measuring function; the overload restriction of work hanging basket, man cage can be controlled; when load-carrying exceedes setting value; its meeting automatic alarm, it can control to shut down, until the effect of safety guard-safeguard automatically when the limit value is reached.This changed course dynamometry pulley is prior art device, existing explanation above its essential structure.
Work hanging basket 11 in the present invention is mainly as workplatform and deposit working Work tool, the transport that man cage 9 is gone into the well on staff.
When vertical shaft digs the stage or carries out lining cutting, supporting, grouting construction to vertical shaft, work hanging basket is required.Drawbar frame 18 is by four hoist cable 21 tractive connection work hanging baskets 11, drawbar frame two ends are respectively provided with pulley 10, hanging basket steel rope 12 wore the pulley 10 at two ends, this steel rope one end upwards extends the hanging basket steel rope attachment point 6 being fixed on shaft top, the other end upwards extend pass changed course pulley one B5 and changed course pulley one A3 after be connected in the reel of hanging basket rack winch 1.Operation is put in leading of hanging basket rack winch, realizes work cage lifting and runs.
Man cage 9 in the present invention arrives for carrying work personnel or leaves the device of work hanging basket.
Man cage steel rope 13 has two for man cage steel rope A131 and man cage steel rope B132; The card rope sling 20 of the steel rope catching device of man cage both sides is connected in after the lower end of these two man cage steel ropes passes the changed course pulley at man cage top respectively.The rope guiding hole 19 of man cage both sides wears translateral hanging basket steel rope 12.Described two man cage steel ropes upwards extend wear two changed course pulley two B8 respectively after pass two changed course pulley two A4, then after passing two pairs of planar guide pulleys 17, be connected in two reels of coaxial twin drum winch 2 respectively.Coaxial twin drum winch leads puts operation, realizes man cage lifting and runs.
Fig. 1 indicates the excavation rock ballast 15 produced in vertical shaft Enlargement excavation and is positioned at silo bottom, with the loader 16 in the side path that silo bottom is through for being transported by excavation rock ballast 15.Vertical shaft in Fig. 1 is for example be arranged in a mountain, and the side path through with silo bottom is for example the passage be situated at the foot of a hill, and is for example the passage being positioned at mountain top or hill-side with the through side path in vertical shaft top or top.
Two changed course pulley two B8 are connected in oil cylinder A piston rod 711 and oil cylinder B piston rod 721 respectively.Two reels of coaxial twin drum winch can the described two man cage steel ropes of constant speed traction simultaneously.Once there is difference in two man cage rope traction speed, as a winding reel arrangement overlaps, then this root steel rope is in relative tension, and another root is in relative relaxation state, as Fig. 5 shows, when man cage steel rope B132 strains relatively, man cage steel rope A131 relative relaxation, now oil cylinder B piston rod 721 is drawn out, oil cylinder B hydraulic oil 722 is squeezed and flows to balancing cylinder A71 cylinder barrel by connecting pipe 22, oil cylinder A hydraulic oil 712 volume increases, the piston of balancing cylinder A moves to oil cylinder A cylinder barrel cavity 713 direction, oil cylinder A piston rod 711 is pulled to inside contract, the man cage steel rope A131 of relative relaxation is strained, when the piston of balancing cylinder A moves to oil cylinder A cylinder barrel cavity direction, chamber air is discharged from oil cylinder A air extractor vent 714.Man cage steel rope A131 strains relatively, and Principles of Regulation during man cage steel rope B132 relative relaxation similarly.
The guarantee of transporting safely of man cage is mainly following several respects:
1. adopt double-steel wire rope traction to play duplicate protection.The effect of balancing cylinder 7 automatically regulates in two man cage steel rope 13 distraction procedure to occur that length and degree of tightness differ the non-equilibrium state caused.
2. alter course pulley two A4 for changed course dynamometry pulley, have and prevent man cage 9 from overloading and play warning and auto-stop effect.
3. the auxiliary device 20 of man cage steel wire rope grip has been installed, i.e. falling protector, when there is the breakdown simultaneously of two haulage cables in man cage 9, by the effect of connecting rod mechanism spring, the auxiliary device 20 of man cage steel wire rope grip can clamp hanging basket steel rope 12 instantaneously, make man cage 9 stop being hung on hanging basket steel rope and not dropping, effectively ensure man cage safe in operation.Because work hangs blue 11 bearing capacities relatively greatly, therefore hanging basket steel rope 12 is relatively thick; And the hanging basket 11 that works runs time different with man cage 9; Because hanging basket steel rope 12 is when mounted through the rope guiding hole 19 of man cage, therefore hanging basket steel rope 12 is simultaneously as the safety rope of man cage 9.
