Description
Technical field
The utility model belongs to engineering construction manufacturing field of equipment, relates in particular to high slope construction prestressed cable field.
Background technology
Along with sustainable development and the continuous demand to the energy of Chinese national economy, country implements grand strategy to develop western regions, especially " transferring electricity from the west to the east " strategy, for hydroelectric development construction has brought unprecedented good opportunity.The engineering fields such as existing water power, railway and highway are progressively shifted to the dangerously steep high mountain gorge area of physical features by Plain opening, relate to a large amount of high slope cable bolting constructions in engineering construction.
At present, the domestic lowering anchor cable construction methods of concentrating rope under a large amount of manpowers that rely on that adopt more.Adopt the method, can't help needing a large amount of manpower and materials, and lower Suo Sudu is slow, cost is high, security risk is also larger.
Harmonious society advocates " people-oriented ", hommization, mechanized construction have become the most important condition of engineering construction project, therefore, and from safety, economic angle, solve current domestic anchor cable and mostly be the present situation that relies on rope under concentrated a large amount of manpowers, seemed particularly important.
Summary of the invention
Problem to be solved in the utility model provides rope equipment under the fireballing automation of a kind of simple to operate, mobile flexible, lower rope exactly for above deficiency.Its technical scheme is as follows:
It comprises frame, mobile piston and jack, and the cylinder bottom of jack is fixed in frame, and mobile piston is connected with the piston rod of jack; In mobile piston both sides, weld respectively Π shape bracing frame, the bipod inner side of Π shape bracing frame forms chute, inserts eccentric shaft in chute; On eccentric shaft, be inserted in eccentric wheel, on mobile piston surface, between two Π shape bracing frames, be provided with kerve.
Compared with prior art, the beneficial effect the utlity model has is:
This device body is light, and flexibly mobile, Installation and Debugging are simple, are applicable to different parts, different size model anchor cable.Adopt this lower rope equipment construction, lower rope process support staff is few, easy to operate, and lower Suo Sudu is fast, safe and reliable.Solved current lowering anchor cable construction and can only adopt the backward problem of concentrating rope under a large amount of manpowers, cost is low.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model top view;
Fig. 3 is Figure 1A-A sectional view.
The specific embodiment
Referring to Fig. 1-Fig. 3, the utility model comprises frame 1, mobile piston 4 and jack 3, the cylinder bottom of jack 3 is fixed in frame 1, and mobile piston 4 is connected by bolt 12 with the piston rod of jack 3, and ejecting of jack piston rod comes and goes mobile with the drive mobile piston that bounces back along frame; In mobile piston 4 both sides, weld respectively Π shape bracing frame 9, the bipod inner side of Π shape bracing frame 9 forms chute 9.1, inserts eccentric shaft 6 in chute 9.1, and eccentric shaft can move up and down in chute; On eccentric shaft 6, be inserted in eccentric wheel 5, on mobile piston 4 surfaces, between two Π shape bracing frames 9, be provided with kerve 8.
Described eccentric wheel 5 rough surface, half section is arcuate structure.
Different with the ratio of smallest cross-sectional diameter in view of the maximum cross-section diameter of different size model anchor cable, 2～3 axle center holes 7 are set on eccentric wheel and for eccentric shaft 6, pass.
The cross section of described kerve 8 is arcuate structure, forms ellipsoidal structure with eccentric wheel 5 in same cross section.
At chute 9.1 tops, adjusting bolt 10 and adjusting nut 11 are installed, by adjusting bolt, are stretched into the length of chute, control the move up and down scope of eccentric shaft in chute, reach the object of the different size model anchor cable of constructing.
Described jack 3 is connected with electric hydraulic pump 13 by high-pressure oil pipe 14.
Concrete lower rope step is as follows:
Step 1: frame 1 is taken into account to anchor cable placing direction by anchor cable hole hole to direction simultaneously and place, after frame is well placed, for preventing machine frame movement, adopt movable fixedly snap ring 2 that frame is fixed on framed bent steel pipe.
Step 2: adopt connecting bolt 12 to be connected and fixed the cylinder bottom seat of jack 3 and frame 1.Mobile piston 4 adopts connecting bolt 12 to be connected and fixed with the piston rod of jack 3.
Step 3: adopt high-pressure oil pipe 14 that jack 3 is connected with electric hydraulic pump 13, guarantee that electric hydraulic pump can be normally to jack conveying or recovery hydraulic oil.
Step 4: anchor cable is put into fixator kerve 8 along frame axis direction.Anchor head is put into anchor cable hole.
Step 5: eccentric wheel 5 is put between two Π shape bracing frames 9, choose suitable axle center hole 7, eccentric shaft 6 passes from the bipod inner side of the Π shape structure of a side Π shape bracing frame 9, through the axle center hole of choosing, then passes the bipod inner side of the Π shape structure of opposite side Π shape bracing frame 9.
Step 6: according to anchor cable cross-sectional sizes, transfer two adjusting bolts 10 of Π shape bracing frame 9 tops simultaneously, control the moving range of eccentric shaft 6 chute inside Π shape bracing frame 9 Π shape structure bipods.
Step 7: the motor that starts electric hydraulic pump 13, by the hand-operated direction valve commutation oil transportation state of electric hydraulic pump 13, the piston rod of jack 3 ejects forward, promoting mobile piston 4 moves forward along frame 1, mobile piston 4 drives kerve 8 and Π shape bracing frame 9 to move forward, Π shape bracing frame 9 drives eccentric shaft 6 to move forward, eccentric shaft 6 band movable eccentric wheels 5 move forward, thereby make eccentric wheel 5 and anchor cable produce relative motion, because of eccentric wheel rough surface, add eccentric wheel itself and there is constant weight, make to produce frictional force between eccentric wheel and anchor cable, eccentric wheel 5 rotates around eccentric shaft 6 under frictional force effect, cause space between eccentric wheel 5 and kerve 8 to diminish, thereby anchor cable is firmly blocked between eccentric wheel 5 and kerve 8, thereby make anchor cable continuing to eject in anchor cable hole hole and move with jack, send in hole.
Step 8: by the hand-operated direction valve commutation oil return state of electric hydraulic pump 13, the piston rod of jack 3 bounces back backward, pull mobile piston 4 to move backward along frame 1, mobile piston 4 drives kerve 8 and Π shape bracing frame 9 to move backward, Π shape bracing frame 9 drives eccentric shaft 6 to move backward, eccentric shaft 6 band movable eccentric wheels 5 move backward, thereby make eccentric wheel 6 and anchor cable produce relative motion, because of eccentric wheel rough surface, add eccentric wheel itself and there is constant weight, make to produce frictional force between eccentric wheel and anchor cable, eccentric wheel 5 counter-rotates around eccentric shaft 6 under frictional force effect, cause space between eccentric wheel 5 and kerve 8 to become large, anchor cable separates with eccentric wheel 5 and kerve 8, mobile piston 4 while bouncing back with jack piston rod, do not drive anchor cable after move.
Step 9: repeating step 7 and step 8, until whole bundle anchor cable is sent in anchor cable hole.
