The utility model content
In view of this, the purpose of this utility model provides a kind of concentrated rope pulling device, can will organize the folding and unfolding and the adjustment of stay cord by centralized control all directions top layer stay cord more, guarantee the jacking equipment vertical lifting, reduce labour intensity, reduced operating personal quantity, control is simple, and lifting is steady, safety.
Concentrated rope pulling device of the present utility model, comprise casing, rotating shaft and the reel that cooperates with the rotating shaft transmission, also comprise the ratchet catch gear, described ratchet catch gear comprise ratchet and with the ratchet of rotating shaft in the circumferencial direction heavy keying fit, described ratchet is with respect to the hinged formation lever construction of casing, the resistance point of ratchet produces drag torque direction engagement at stay cord to ratchet with ratchet, at least three on described reel, each reel all cooperates with the rotating shaft transmission by an overriding clutch, and described overriding clutch produces the engagement of drag torque direction at stay cord to reel.
Further, described ratchet is provided with engage spring, and described engage spring one end connects ratchet, and the other end is fixed with respect to casing, and is provided with the tensile stress that makes ratchet and ratchet engaged;
Further, with the corresponding release rod that is provided with of power point of ratchet, described release rod is opposite with spring tensile stress direction to the thrust direction of ratchet power point;
Further, the corresponding hinged pressing plate that is provided with stay cord on the elastic compression reel with reel on the described casing;
Further, the stay cord end that is wrapped on the reel connects a hook, also is provided with two groups of pulleys on the stay cord, and two groups of pulleys are provided with a hook respectively;
Further, described roller end and rotating shaft are provided with manual rocking handle seat in the circumferencial direction heavy keying fit.
The beneficial effects of the utility model: concentrated rope pulling device of the present utility model, adopt and concentrate rope pulling device to carry out stay cord control from different directions, folding and unfolding and adjustment by one man operation control all directions top layer stay cord guarantee the jacking equipment vertical lifting, control is simple, and lifting is steady, safety.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 be Fig. 1 along A to view.
The specific embodiment
Fig. 1 is a structural representation of the present utility model, Fig. 2 be Fig. 1 along A to view, as shown in the figure: the concentrated rope pulling device of present embodiment, comprise casing 2, rotating shaft 11 and the reel 1 that cooperates with rotating shaft 11 transmissions, also comprise ratchet catch gear 6, described ratchet catch gear 6 comprise ratchet 62 and with the ratchet 61 of rotating shaft 11 in the circumferencial direction heavy keying fit, described ratchet 62 is with respect to casing 2 hinged formation lever constructions, the resistance point of ratchet 62 produces drag torque direction engagement at stay cord to ratchet 61 with ratchet 61,1 at least three on described reel, in the present embodiment, reel 1 quantity is three; Each reel 1 all cooperates with rotating shaft 11 transmissions by an overriding clutch 10, and described overriding clutch 10 produces the engagement of drag torque direction at stay cord to reel 1.
In the present embodiment, described ratchet 62 is provided with engage spring 63, and described engage spring 63 1 ends connect ratchet 62, and the other end is fixing with respect to casing 2, and is provided with and makes ratchet 62 and ratchet 61 ingear tensile stresss; Carry out the normality engagement by engage spring 63, simple to operate, engagement is reliable.
In the present embodiment, with the corresponding release rod 8 that is provided with of power point of ratchet 62, the thrust direction of 8 pairs of ratchet 62 power points of described release rod is opposite with engage spring 63 tensile stress directions; Separate driving by release rod 8 structures, simple and compact for structure, cost of manufacture is low.
In the present embodiment, on the described casing 2 with the reel 1 corresponding hinged pressing plate 9 that is provided with stay cord on the elastic compression reel; Owing to adopt pressing plate 9, make the stay cord queueing discipline, avoid occurring steel rope and arrange problems such as loose entanglement, protect steel rope effectively, improved service life.
In the present embodiment, stay cord 3 ends that are wrapped on the reel 1 connect a hook 5, also be provided with 4, two groups of pulleys 4 of two groups of pulleys on the stay cord 3 hook be set respectively, as required by pulley 4 and hook make stay cord be distributed in lifting bar around, easy to use; Rotating shaft 11 ends and rotating shaft 11 are provided with manual rocking handle seat 7 in the circumferencial direction heavy keying fit.
The utility model is when last lift operations, drive release rod, the rotating drum stay cord is drawn out, when skew takes place owing to factors such as wind carry in the jacking equipment top, by adjusting the rotating speed of reel combination, jacking equipment is adjusted to vertically, keep vertically, steadily rise, when wind carries when excessive, rocking handle can be inserted in manual rocking handle seat and drive reel and rotate centralized control to put the speed of stay cord; After rising to specified altitude,, can adjust reel one by one, make jacking equipment as far as possible vertically, tighten up stay cord then owing to adopt the overriding clutch structure; During step-down operation, rocking handle is inserted in the contrarotation of rocking handle seat comes centralized control to reel the speed of rope, when skew takes place owing to factors such as wind carry in the jacking equipment top, only need one man operation, by adjusting the rotating speed of reel combination, thereby jacking equipment is adjusted to vertical position, keep vertical, the steadily decline of jacking equipment.
