The specific embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is elaborated:
Like Fig. 1, shown in Figure 2; The two high pulling torque duplex type elevator structures that drive of a kind of board-plugging device; Comprise top pulleys group 1, steel sleeve 2, tension pulley block group 3, elevator 7, elevator cylinder 8, lower pulley group 9, first motor 10, first planetary reducer 11, second motor 12, second planetary reducer 13; Elevator 7 is connected with an end of first steel cable 14, second steel cable 15 respectively; First steel cable 14, second steel cable 15 begin to twine from the two ends of elevator 7 respectively, and the other end of first steel cable 14 is connected with steel sleeve 2 through top pulleys group 1 back, are connected with steel sleeve 2 after the other end process tension pulley block group 3 of second steel cable 15, the lower pulley group 9; Elevator cylinder 8 is set on the elevator 7, and the two ends of elevator cylinder 8 are provided with first planetary reducer 11 respectively, second planetary reducer, 13, the first planetary reducers 11 are connected with first motor 10, and second planetary reducer 13 is connected with second motor 12.
As shown in Figure 1, the present invention arranges leading sheave group 4 on the steel cable between tension pulley block group 3 and the elevator 7.
As shown in Figure 1, connect tensioning hydro-cylinder 5 on the tension pulley block group 3 of the present invention.
As shown in Figure 1, connect self adaptation tensioning elastic body 6 on the tensioning hydro-cylinder 5 of the present invention.
As shown in Figure 1; Hoisting system is equipped with in the present invention on equipment; Twine first steel cable 14, second steel cable 15 on the elevator 7 respectively; First steel cable 14, second steel cable 15 begin to twine (the steel cable rotation direction is identical) from the two ends of elevator respectively, and second steel cable 15 is back to the bottom of equipment through its top leading sheave group 4 and tension pulley block group 3, pass through again lower pulley group 9 up bolt on steel sleeve 2; First steel cable 14 is directly up to equipment top pulleys group 1, returns down also bolt on steel sleeve 2.When elevator 7 rotated insertion, second steel cable 15 was regained, and steel sleeve inserts soil down, and first steel cable 14 is put rope; When elevator 7 counter-rotation, first steel cable 14 is regained, and through top pulleys group 1 steel sleeve 2 is extracted soil, and second steel cable 15 is put rope.
As shown in Figure 2, the present invention installs first motor 10, first planetary reducer 11, second motor 12, second planetary reducer 13 respectively at elevator cylinder 8 two ends.Two motor oil oral sex forks join, and such two motor switched in opposite exert oneself for simultaneously elevator cylinder 8.
Connect tensioning hydro-cylinder 5 on the tension pulley block group 3 of the present invention, tensioning hydro-cylinder 5 is connected with self adaptation tensioning elastic body 6 again.Because the existence of the adsorption affinity f of sleeve pipe deadweight G and soil, pulling force is bigger about 1.5 times than insertion force in the working process, and to extend will be than tube drawing the time steel cable elongation little for steel cable when also being intubate.Simultaneously as can be seen from Figure 1; Confirmed that by the installation site of elevator 7 intubate first steel cable 14 has been lacked much than tube drawing second steel cable 15 when maximum pulling force (also being that sleeve pipe is inserted into the innermost); Second steel cable, 15 elongations had been lacked quite a few times when therefore, the elongation of first steel cable 14 was than tube drawing during intubate.Therefore, as shown in Figure 1, we are installed in tensioning hydro-cylinder 5 on the body frame of bottom; And a self adaptation tensioning elastic body 6 has been installed in tensioning hydro-cylinder 5 bottoms; This self adaptation tensioning elastic body 6 is restrained simultaneously stroke necessarily, after compression arrives the trip, the supporting power of oil cylinder (Zhang Shengli) will be provided by the oil cylinder lower bearing pin; To guarantee that there is certain predetermincd tension F0 the closed loop inside of being made up of two steel cables, the big young pathbreaker of this predetermincd tension is near the required insertion force of intubate (F0 ≈ f1).At this moment the preparatory elongation of stretching of first steel cable 14 is d1, and the preparatory elongation of second steel cable 15 is d2, and when the steel cable joint of steel sleeve 2 was got back to the equipment top, the not coiling length of first steel cable 14 and second steel cable 15 was approximately equal, so d1 ≈ d2.
When steel sleeve 2 of the present invention is got back to the top and is inserted operation: F1=F2-G, at this moment: F1=F0, also promptly: F2=F0+G
When inserting operation: F1=f1+F2-G
When carrying out the tube drawing operation: F2=f1+F1+G
Wherein: F1 is the pulling force of first steel cable 14, and F2 is the pulling force of second steel cable 15, and G is the deadweight of steel sleeve, soil resistance force when f1 is intubate, soil resistance force when f2 is tube drawing
When the intubate operation; Because the resistance of soil makes the corresponding increase of tension force of first steel cable 14, elongation is linear the increasing with the increase of putting forth effort also; The elongation of corresponding second steel cable 15 is also corresponding to be reduced; The equal in length that the length that reduces and first steel cable 14 increase, also being that F2 is corresponding reduces, and remains on the state of balance.When soil resistance force increases near the steel cable predetermincd tension (f1 ≈ F0), the double length when first steel cable 14 will be elongated to pretension, at this moment second steel cable, 15 elongations are also withdrawn and are approached 0, also are the tensile force f 1 ≈ f1-G of first steel cable 14.Second steel cable 15 is not loose yet, and elevator is in proper working order.
When carrying out the tube drawing operation, because the resistance of soil and the deadweight of steel sleeve, the pulling force of first steel cable 14 was much bigger when the pulling force of second steel cable 15 can be than intubate.And this moment because steel sleeve 2 is most of or all insert ground, the not coiling length of first steel cable 14 is shorter, the twice of the length of second steel cable 15 during near intubate not; Therefore, when tube drawing, the elongation of second steel cable 15 will be the twice during intubate not; At this moment first steel cable 14 will relax, and self adaptation tensioning this moment elastic body 6 will play a role, and oil cylinder is risen; To compensate the loose of first steel cable 14; And make first steel cable 14 keep the Zhang Shengli that produces by elastic body elastic force, and first steel cable 14 will can disorder cable not occur on elevator 7, and machine still can normal operation.
