Described man cage trailer coupling is comprised of coaxial twin drum winch 2, two groups of planar guide pulleys 17, two 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, pulley two A that wherein alter course, for changed course dynamometry pulley, are connected with soft connecting pipe 22 between the oil pocket of two balancing cylinders, 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 connecting with vertical shaft top, two balancing cylinders are arranged at the fixed mount at described vertical shaft top, two changed course pulley two B are installed on respectively the piston rod outer end of described balancing cylinder, two card rope slings 20 of one pair of steel rope catching device are fixed on radially symmetrically man cage and are set in respectively the section corresponding with described hanging basket steel rope attachment point and changed course pulley one B of described hanging basket steel rope, two man cage steel ropes are set in two changed course pulley two B after being connected in correspondingly respectively successively two card rope slings of steel rope catching device, be set in again two reels that are connected in coaxial twin drum winch after two changed courses pulley two A and two groups of planar guide pulleys, every group, described two groups of planar guide pulleys 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 respectively the section corresponding with hanging basket steel rope attachment point 6 and changed course pulley one B5 of hanging basket steel rope, the hanging basket steel rope of both sides of take while making man cage lifting carries over the oscilaltion of hanging basket steel rope, steady ordered as guiding.
Changed course pulley one A in the utility model and changed course pulley two A are changed course dynamometry pulley; its function one is as hanging basket steel rope, man cage steel rope tractive guiding; the 2nd, there is sensor force measuring function; can control the overload restriction of work hanging basket, man cage; when load-carrying surpasses setting value; its meeting automatic alarm, when the value of reaching capacity, its can automatically be controlled and shut down, until the effect of safety guard-safeguard.This changed course dynamometry pulley is prior art device, and it is existing explanation above essential structure.
Work hanging basket 11 in the utility model is mainly as workplatform and deposit working Work tool, the transportation of man cage 9 for going into the well on staff.
When vertical shaft digs the stage or vertical shaft is carried out to lining cutting, supporting, grouting construction, work hanging basket is essential.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 extends upward the hanging basket steel rope attachment point 6 that is fixed on vertical shaft top, and the other end extends upward and passes the reel that is connected in hanging basket rack winch 1 after changed course pulley one B5 and changed course pulley one A3.Operation is put in leading of hanging basket rack winch, realizes the operation of work cage lifting.
Man cage 9 in the utility model is for delivering staff, to arrive or leave 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 lower end of these two man cage steel ropes passes respectively the card rope sling 20 that is connected in the steel rope catching device of man cage both sides after the changed course pulley at man cage top.The rope guiding hole 19 of man cage both sides is worn translateral hanging basket steel rope 12.Described two man cage steel ropes pass two changed course pulley two A4 after extending upward and wearing respectively two changed course pulley two B8, then pass two pairs of rear two reels that are connected in respectively coaxial twin drum winch 2 of planar guide pulley 17.Coaxial twin drum winch leads puts operation, realizes man cage lifting operation.
Fig. 1 expresses vertical shaft and digs the excavation rock ballast 15 producing in construction and be positioned at silo bottom, and the loader 16 in the side path connecting with silo bottom is for transporting excavation rock ballast 15.Vertical shaft in Fig. 1 is to be for example arranged in a mountain, and the side path connecting with silo bottom is for example the passage being situated at the foot of a hill, and the side path connecting with vertical shaft top or top is for example the passage that is positioned at mountain top or hill-side.
Two changed course pulley two B8 are connected in respectively oil cylinder A piston rod 711 and oil cylinder B piston rod 721.Two reels of coaxial twin drum winch simultaneously constant speed draw described two man cage steel ropes.Once there is difference in two man cage rope traction speed, as a winding reel, arrange and overlap, this root steel rope is in relative tension, and another root is in relative relaxed state, as Fig. 5 shows, when man cage steel rope, B132 strains relatively, man cage steel rope A131 is relatively lax, 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 volumes increase, the piston of balancing cylinder A moves to oil cylinder A cylinder barrel cavity 713 directions, pull oil cylinder A piston rod 711 to inside contract, by relatively lax man cage steel rope A131 tension, when the piston of balancing cylinder A moves to oil cylinder A cylinder barrel cavity direction, in chamber, air is discharged from oil cylinder A air extractor vent 714.Man cage steel rope A131 strains relatively, and Principles of Regulation when man cage steel rope B132 is relatively lax similarly.
The guarantee of transporting safely of man cage is mainly following several respects:
1. adopt double-steel wire rope traction can play duplicate protection.The effect of balancing cylinder 7 is automatically to regulate in two man cage steel rope 13 distraction procedure and occur the non-equilibrium state that length and degree of tightness differ and cause.
2. changed course pulley two A4 are changed course dynamometry pulley, have the man cage of preventing 9 and overload and play and report to the police and auto-stop effect.
3. the auxiliary device 20 of man cage steel wire rope grip has been installed, it is 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 moment, make man cage 9 stop being hung on hanging basket steel rope and do not drop, effectively guaranteeing man cage safe in operation.Due to work, to hang blue 11 bearing capacities relatively large, therefore hanging basket steel rope 12 is relatively thick; And operation when work hanging basket 11 is different with man cage 9; Because hanging basket steel rope 12 passes the rope guiding hole 19 of man cage when mounted, so 12 whiles of hanging basket steel rope are as the safety rope of man cage 9.
