Abstract
The utility model discloses a steel strand pulling device. The device comprises a winch, a preembedded part I and a preembedded part II, wherein a fixed pulley set I and a fixed pulley set II are respectively arranged on the preembedded part I and the preembedded part II; the preembedded part II is arranged above an anchor mouth of a steel strand to be pulled; the preembedded part I is arranged on the top of a beam body; and a steel wire rope of the winch sequentially passes through the fixed pulley set I and the fixed pulley set II and is connected with the steel strand to be pulled. By the device, the fixed pulley sets are arranged above the anchor mouth of the steel strand to be pulled and on the top of the beam body, the preembedded part are fixed by the beam body, so that the direction of traction force applied to steel strand during pulling can be changed, the problem of the territorial restriction is solved; the device is suitable for prestressed rib pulling construction of large-span continuous beams without limitation of sites and is safe and practical; the working efficiency can be improved; the shortcoming that steel strands cannot be constructed conveniently due to overhigh beam bodies is overcome; and the cost is saved.
Description
Technical field
The utility model relates to a kind of pull-through machine, relates in particular to a kind of pull-through machine that is used for prestress wire.
Background technology
At present bridge prestress lashing technology adopts hoist engine whole bundle direct puncture or the single direct puncture technology of strand pulling machine basically, but is subject to the construction plant restriction during the single lashing of hoist engine whole bundle direct puncture or strand pulling machine.Particularly bridge development span increases gradually in recent years, and the usage quantity of prestress wire significantly increases, and the difficulty of construction of growing the lashing of bundle steel strand is quite big, only adopts manual work, hoist engine or strand pulling machine can not accomplish lashing work safely and effectively.
Summary of the invention
The utility model technical problem to be solved is the deficiency that has overcome traditional mechanical, and a kind of prestressing force lashing technology of safe ready is provided.
For solving this technical problem; The utility model provides a kind of steel strand penetrating device; Comprise hoist engine, built-in fitting I and built-in fitting II, be respectively arranged with fixed block group I and fixed block group II on built-in fitting I and the built-in fitting II, said built-in fitting II is arranged at the anchor mouth top of treating steel strand; Built-in fitting I is arranged at beam body end face, and the hoist engine wire rope is connected with treating steel strand through fixed block group I, fixed block group II successively.
The tractive force of said hoist engine is 5 ~ 10 tons.
The rope capacity of said hoist engine is 2 times of length to steel strand.
The bearing capacity of said fixed block group I, fixed block group II is 12 tons.
Beneficial effect: the utility model is treating to reach beam body end face fixed block group above the anchor mouth of steel strand, adopts beam body built-in fitting to fix, and can change the force direction that receives of steel strand lashing tractive force; Solve region restricted problem, be applicable to the presstressed reinforcing steel lashing construction of the large-span continuous beam that the place is limited, safe, practical; Can increase work efficiency; Overcome because the beam height is spent greatly, and be unfavorable for the condition restriction of constructing, the saving cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 hoist engine, 2 built-in fitting I, 3 built-in fitting II, 4 fixed block group I, 5 fixed block group II, 6 wire rope, 7 are treated steel strand.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done specific descriptions.
Shown in Figure 1 is the structural representation of the utility model.
The utility model provides a kind of steel strand penetrating device, comprises hoist engine 1, built-in fitting I and built-in fitting II, is respectively arranged with fixed block group I and fixed block group II on built-in fitting I and the built-in fitting II.
Said built-in fitting II is arranged at the anchor mouth top of treating steel strand; Built-in fitting I is arranged at beam body end face; The wire rope of hoist engine 1 is connected with treating steel strand through fixed block group I, fixed block group II successively, can change the force direction that receives of steel strand lashing tractive force, solves region restricted problem.
The tractive force of said hoist engine 1 is preferably 5 ~ 10 tons greater than 5 tons.
The wire rope of said hoist engine 1 is equipped with length and is not less than 1.5 times of steel strand length, is preferably 2 times of length to steel strand.
The bearing capacity of said fixed block group I and fixed block group II is not less than 10 tons, is preferably 12 tons.
Foundation is confirmed in the position of two fixed block groups of the utility model: through formed two the angle α of the wire rope of two assembly pulleys, β, can adjust arbitrarily according to on-site actual situations, but for safety, wire rope must not intersect in the same plane.
The utility model is applicable to the presstressed reinforcing steel lashing construction of the large-span continuous beam that the place is limited, and is safe, practical, can increase work efficiency, and overcomes because the beam height is spent greatly, and is unfavorable for the condition restriction of constructing, the saving cost.
The above-mentioned embodiment of the utility model just illustrates, and is not only, all in the utility model scope or the change that is equal in the scope of the utility model all surrounded by the utility model.
