Description
Technical field
The utility model relates to cable duct and patrols and examines field, specifically a kind of cable cover hoisting device.
Background technology
Cable duct is the underground structure for cable laying, and cable duct 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 impact work efficiency of patrolling and examining not only also may make patrol officer's injured (cable cover weigh wounded or scratch and so on) simultaneously.
The patent No. is " ZL201320777874.9 ", the patent that name is called " substation's packaged type cable cover crane carriage " discloses a kind of vehicle structure, this structural entity is a dolly, a hand winch is set on dolly rises cable cover, then promoting dolly removes cable cover, although comparing traditional cable cover of manually prying open is to have facilitated much, but still there is certain problem, such as, because cable cover itself is comparatively heavy, if employing hand winch, for women and older, relatively painstaking, and to control hand winch on one side, to check cable on one side, this just needs larger human input to a certain extent.Because the hook of this crane carriage belongs to the structure that can directly hook cable cover, therefore also easily skid off, safety can not get ensureing.
Utility model content
The purpose of this utility model is to provide a kind of cable cover hoisting device, and the cable cover lifting mode solving in the past is comparatively required great effort, and needs larger human input, and safety can not get the problem ensureing simultaneously.
The utility model for achieving the above object, is realized by the following technical solutions: a kind of cable cover hoisting device, and two groups of rollers that comprise vehicle frame and be arranged on vehicle frame below, every group of roller comprises two rollers, two rollers connect by rotating shaft;
Described vehicle frame comprises four root posts, top board and bearing plate, and described top board is positioned at the top of four root posts, and the center of top board is provided with through hole, and the outer of top board is provided with fixed pulley, and the center of described bearing plate is provided with the big hole that can make cable cover pass;
Also comprise rope and hook, one end of described rope is fixed therein the middle part of a rotating shaft, and the other end, successively through fixed pulley, through hole, is then connected with hook;
Described hook comprises central tube and is connected to two cantilevers on central tube, and two cantilever symmetries are fixed on the both sides of central tube, and 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.
This programme has two important component parts, and one is lift portion, and another is hook portion, lift portion design is very ingenious, lift portion comprises rotating shaft, rope, fixed pulley and hook, one end of rope is fixed in rotating shaft, when promoting car body, realize kinking and the unwrapping wire of rope in rotating shaft, realize the lifting of hook, thereby without increasing again separately the lifting of controlling hook of tray and so on, make more reasonable structure, more convenient operation, and hook portion design is also very ingenious, with inserted link, pin and lever be combined into one can switch right angle hook, 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 with arc hook, replace reluctantly, but there is it self problem in arc hook, and the hook of this programme is a kind of controlled right angle 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, inserted link now, lever, pin just can insert in the aperture of cable cover downwards, 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, inserted link now, lever, pin forms a right angle hook, inflexibly cable cover is hooked, after cable cover is resetted, drop-down arm-tie again, lever is packed up, from the aperture of cable cover, take off hook.
Further, as preferred version, attachment point and line fixed pulley between of described rope in rotating shaft is vertical state.
Further, as preferred version, described bearing plate is parallel with top board.
Further, as preferred version, described bearing plate is fixed on the midpoint of four root posts.
The utility model compared with prior art, has the following advantages and beneficial effect:
(1) the utility model passes through the combination dexterously of rotating shaft, rope, fixed pulley and hook, formed a lifting mechanism, one end of rope has been fixed in rotating shaft, when promoting car body, realize kinking and the unwrapping wire of rope in rotating shaft, realize the lifting of hook, thereby without increasing again separately the lifting of controlling hook of tray and so on, make more reasonable structure, more convenient operation, simultaneously more laborsaving, only need a people can realize operation, can reduce to a certain extent the input of manpower.
(2) for the utility model inserted link, pin and lever be combined into one can switch right angle hook, facilitated the insertion of hook and taken out after hooking cable cover, right angle hook hooks cover plate inflexibly, make hook there is no the possibility of landing completely, thereby improved the reliability of hook and the safety of operation.
