Abstract
Disclosed in the utility model is a hook structure for lifting a cable well cover. The hook structure comprises a center cylinder and two cantilevers connected to the center cylinder. The two cantilevers are symmetrically fixed at the two sides of the center cylinder; vertical insertion rods are fixed at far ends of the two cantilevers; and blocking rods perpendicularly to the insertion rods are fixed at the lower ends of the insertion rods. In addition, the hook structure also includes moving rods and springs; the moving rods are movably fixed at the connection portions of the insertion rods and the blocking rods. One end of each spring is fixed at the middle portion of one insertion rod and the other end is fixed at the moving portion of one moving rod. Besides, the hook structure also includes pulling ropes and a pulling plate; one end of each pulling rope is fixedly connected with the free end of the moving rod; and the other end of the pulling rod penetrates into the center cylinder, extends out of the lower end of the center cylinder, and is fixedly connected with the pulling plate. And sleeve rings also arranged and are fixed at connection portions of the cantilevers and the insertion rods; and the pulling ropes penetrates the sleeve rings. On the basis of the structure, the hook reliability is improved; and the slip-off possibility of the cable cover plate during lifting can be prevented, so that security is enhanced.
Description
Technical field
The utility model relates to cable trough and patrols and examines field, specifically for promoting the hook structure of cable well lid.
Background technology
Cable trough is the underground structure for cable laying, and cable trough is provided with well head, and well head covers with cable cover.When patrolling and examining, patrol officer need to move cable cover away, cable is checked, because hoist cable cover plate does not have special instrument or equipment, generally can only pry open by patrol officer, then move, because cable cover is heavier, cause operation very inconvenient, the not only impact operating efficiency of patrolling and examining also may make patrol officer's injured (cable cover weigh wounded or scratch and so on) simultaneously.At present, some hooks cable cover with linking up with for lifting by crane the device of cable cover, then by lifting means, cable cover is risen, but this hook less stable easily makes cable cover landing, thereby may cause security incident.
Utility model content
The purpose of this utility model is to be provided for promoting the hook structure of cable well lid, and the stability that solves the hook in the past promoting for cable cover is not high, easily causes cable cover landing, causes the problem of security incident.
The utility model for achieving the above object, realize by the following technical solutions: for promoting the hook structure of cable well lid, comprise central tube and be connected to two cantilevers on central tube, two cantilever symmetries are fixed on the both sides of central tube, the far-end of described two cantilevers is fixed with the inserted link that is vertical state, and the lower end of described inserted link is fixed with the pin vertical with inserted link;
Also comprise lever and spring, the length of lever is greater than the length of pin, and described lever is movably fixed to the junction of inserted link and pin, and one end of described spring is fixed on the middle part of inserted link, and the other end is fixed on the middle part of lever, and spring is all the time in compressive state;
Also comprise stay cord and arm-tie, one end of described stay cord is fixedly connected with the free end of lever, and the other end of stay cord penetrates central tube and passes from the lower end of central tube, is then fixedly connected with arm-tie; Also comprise the collar, the described collar is fixed on the junction of cantilever and inserted link, and stay cord is through the collar.
In this programme, with inserted link, pin and lever be combined into one can switch right angle hook, and traditional hook is arc hook, arc hook is for right angle hook, stability is so unreliable, arc hook may skid off from the hole of cable cover, and why do not adopt right angle to link up with to promote cable cover in the past, not get on because basic extension is linked up with at the right angle of general structure, also be not easy to take off, therefore pretty troublesome, just for arc hook replace reluctantly, but there is it self problem in arc hook.This programme is by a kind of controlled right angle of design hook, before hook inserts the aperture on cable cover, drop-down arm-tie, by stay cord, the free end of lever is up drawn, make lever substantially keep vertical state, now inserted link, lever, pin just can insert downwards in the aperture of cable cover, then unclamp arm-tie, under the effect of spring and pin, lever is flicked downwards, make lever become 90 degree right angles with inserted link, now inserted link, lever, right angle hook of pin composition, inflexibly cable cover is hooked, after cable cover is resetted, drop-down arm-tie again, lever is packed up, take off hook from the aperture of cable cover.
Further, as preferred version, the angle that described two cantilevers become is 150 ~ 160 degree.
Further, as preferred version, the inner side of the described collar is provided with a rubber ring.
The utility model compared with prior art, have the following advantages and beneficial effect: the utility model is by being designed to inserted link, lever, pin the version of controlled right angle hook, improve the control of hook to cable cover, make hook there is no the possibility of landing from cable cover, thus stationarity and fail safe while having ensured to promote cable cover; In addition, this hook operates also very convenient in picking and placeing, and on the basis of fail safe, can also increase work efficiency to a certain extent having ensured.
