Description
Technical field:
The utility model relates to a kind of large-tonnage mast guy rope simultaneously pretightening or relaxation system, particularly a kind of large-tonnage mast guy rope simultaneously pretightening or relaxation system that adopts the computing machine synchro control.
Background technology:
Cable wind rope is the important component part in great hoisting engineering middle mast tackling system, plays a part to stablize mast and bears part load in the mast hoisting and hanging.Before the mast carrying, must impose an amount of predetermincd tension to the cable wind rope of mast, its objective is after mast loads, still to guarantee the lifting parameter of being scheduled to substantially, as upright mast do not produce allowed band crooked, tiltedly upright mast still can keep the leaning angle be scheduled to etc. substantially.
The general wire tensioner that is connected in series with in the cable wind rope that adopts of the pretension of traditional cable wind rope, chain block, polyspast are drawn with winch.The large-tonnage mast is all established 6～8 cable wind ropes, traditional cable wind rope pretension is at independently a certain, each predetermincd tension can only rely on operator's experience to be controlled, adopt this method to occur mast easily and lose stable situation, particularly when carrying out the lifting of some large-tonnage reaction towers, because its its mast of back in place needs the certain distance of translation could dismantle mast, the tradition movable mast adopts gradation to move as shown in Figure 1, the concrete operations step has two kinds, and a kind of is the mobile raft-towing behind the mast of inclining earlier; Another kind is the mobile raft-towing hypsokinesis mast of elder generation.No matter adopt which kind of operation, mast is all wanted to move on to position B from position A earlier, behind the adjustment cable wind rope, moves on to position C from position B again, in this process, the adjusting of its cable wind rope power is difficult to realize that many are regulated simultaneously, and the predetermincd tension size is estimated by the operator fully, is difficult to guarantee consistent, thereby less stable, if surpass 100 meters high, the nearly 10000 tons of masts of weight move, and its stability more can't guarantee; In practice of construction, the mast of hoisting large-size retort far surpasses 100 meters, thereby the movable mast difficulty is very big.
The utility model content:
The technical problems to be solved in the utility model is: a kind of many guy rope simultaneously pretightenings of large-tonnage mast or relaxation system that adopts the computing machine synchro control is provided, adopt this system can make that mast remains the equilibrium of forces state in moving, the stressed distribution of cable wind rope is reasonable, mast stable, to solve the problem of the less stable that pre-clamping method that above-mentioned mast adopts traditional cable wind rope in moving exists.
The technical scheme that solves the problems of the technologies described above is: many guy rope simultaneously pretightenings of a kind of large-tonnage mast or relaxation system, by N root cable wind rope, the translation jack of two band displacement pickups, N+2 platform hydraulic power unit, 1 cover control system is formed, every cable wind rope is made up of M bar tensioned prestressing bar, wherein all be in series with by earth anchor, bracing frame, the stretch-draw jack that has pressure sensor, the single cable wind rope tensioning equipment that anchor fitting and adaptor union are formed, control system is to include cable wind rope to loosen the computer remote control system that module and cable wind rope tighten up module, and N+2 platform hydraulic power unit links to each other with the translation jack of stretch-draw jack that has pressure sensor and band displacement pickup respectively by high pressure fuel pipe; Each displacement pickup, pressure sensor link to each other with the control system input end by circuit, and each hydraulic power unit links to each other with control system by control cable; The span of above-mentioned M, N is: 1≤M≤100, N is the even number between 2～20.
Further scheme of the present utility model is: be made up of last clamper, main top, lower gripper, spike as the stretch-draw jack of cable wind rope stretch-draw actuating unit in the system in the single cable wind rope tensioning equipment; On bracing frame, and an end of bracing frame links to each other with earth anchor by bearing pin the stretch-draw jack by bolt; The other end of bracing frame is unsettled, and in adaptor union, adaptor union maybe needs to strain the position by bearing pin with the mast upper end and links to each other anchor fitting with bolt; The M bar tensioned prestressing bar of forming cable wind rope passes anchor fitting, stretch-draw jack by the upper and lower clamper anchoring of anchor fitting, stretch-draw jack, and the span of above-mentioned M is: 1≤M≤100.
In the utility model, the prestressing tendon of forming cable wind rope is steel strand or reinforcing bar, and wherein, it is a kind of that steel strand are best suited for.
Because adopt technique scheme, many guy rope simultaneously pretightenings of the large-tonnage mast of the utility model or relaxation system have following beneficial effect:
One, make in the work progress, mast remains the equilibrium of forces state, mast is stable:
Many guy rope simultaneously pretightenings of the utility model large-tonnage mast or relaxation system have adopted the calculating synchronous control technique, many guy rope simultaneously pretightenings that make mast with loosen, and can be synchronous with the raft-towing moving hormany of mast, make the large-tonnage mast remain the equilibrium of forces state, make large-scale mast keep stabilized conditions in real time, increased the stability of mast.
Two, the stressed distribution of cable wind rope is reasonable:
Because the pretension of cable wind rope has adopted hydraulic jack stretch-draw, and have pressure sensor on the stretch-draw jack again, can detect the size of the bearing capacity of every cable wind rope exactly, simultaneously, can realize the accurate adjusting of every cable wind rope predetermincd tension accurately according to the size of predefined power by computer controlled.
Three, cable wind rope has adopted the cable wind rope that many low loose high-intensity steel strand are formed, and holding capacity is big, flexible arrangement, and the cable wind rope predetermincd tension is unrestricted, can be satisfied with various large-scale masts (pylon) stability requirement.
Four, this system bulk is little, and method of operation is simple, every cable wind rope stretching force shows in real time, intuitively.
Below, in conjunction with the accompanying drawings and embodiments the many guy rope simultaneously pretightenings of large-tonnage mast of the utility model or the technical characterictic of relaxation system are further described.
