Description
Technical field
The utility model relates to a kind of municipal power tool, specifically is inspection shaft lid lifter.
Background technology
Along with the fast development of urbanization process, all kinds of sub-districts, utility structures like the mushrooms after rain emerge in large numbers the corresponding surge of the quantity of urban highway, supporting pipe network; The work capacity of municipal administration, environmental sanitation also grows with each passing day.As the primary work of inspection shaft cleaning, promptly be the unlatching of inspection shaft lid.Traditional well lid opener only is a pick, though instrument is simple, needs two people compounding practice simultaneously, wastes time and energy the labour intensity height.
The utility model content
The purpose of this utility model is the deficiency that overcomes the above-mentioned background technology, provides a kind of inspection shaft lid to promote apparatus, and this lifting apparatus should have easy-to-use, time saving and energy saving, moves flexibly lightly, and makes characteristic of simple.
The technical scheme that the utility model proposes is: inspection shaft lid lifter is characterized in that this lifter comprises body and is installed in activity wheel on the body; The front end of described body is equipped with the rotating key that well lid is used that lifts, and the rear end is shaped on a handle and a rotating spanner; The pull rope mechanism of one transmission pulling force is set between described spanner and the key.
Described pull rope mechanism comprises that key axle, two ends that a wrench shaft, that is hinged on body rear portion and rolling stay cord vertically is hinged on the body front end and fixes a pull bar are separately fixed on the pull bar and are wrapped in stay cord on the wrench shaft, comprise that also several are installed in the body middle part and are used for the transition wheel that stay cord turns to.
The front end of described body also is provided with an extension spring, and this extension spring applies a pulling force opposite with the stay cord direction of pull to pull bar.
Described key next to axis limit also is provided with the baffle plate of a qualification key axle rotational angle.
The top of described key axle is exposed on the body surface and is fixed the label of an indication key rotational axis direction.
The bottom of described body also is shaped on the protective block of a protection key.
Principle of work of the present utility model is: because the mouth that lifts of inspection shaft lid is elongated groove, key needs elder generation to aim at and lifts turn an angle after mouth inserts (about 90 degree) during use, upwards lift then, key just can block to be pricked the edge that lifts mouth and upwards lifts inspection shaft and cover.
During use this lifter is moved to inspection shaft and cover the limit, the pulling spanner makes key turns, pull bar is blocked (direction that can distinguish key according to the label of body front end) when forwarding certain position to by catch, the lifter front end can be moved down this moment to make key insert the mouth that lifts of well lid; Release handle then, key circles round to initial position, firmly presses down handle and can utilize lever principle to upgrade well lid.
The beneficial effects of the utility model are: this lifter has solved to be opened and mobile well lid is wasted time and energy at present, the deficiency that labour intensity is big, it is simple to have manufacture craft, it is convenient to open, move light and handy flexibly, time saving and energy saving, can fully alleviate working strength of workers, can adapt to the advantages such as inspection shaft lid of all size.
Description of drawings
Fig. 1 is a perspective view of the present utility model.
Fig. 2 is the A portion structure for amplifying scheme drawing among Fig. 1.
The specific embodiment
As shown in the figure, inspection shaft lid lifter is characterized in that this lifter comprises body 5 and is installed in activity wheel 4 on the body; The front end of described body is equipped with rotating key 12 (rotation direction is shown in arrow G among Fig. 2), and the rear end is shaped on a handle 1 and a rotating spanner 2; The pull rope mechanism of one transmission pulling force is set between described spanner and the key.
Described pull rope mechanism comprises that key axle 121, two ends that a wrench shaft (spanner is fixed on the wrench shaft), that is hinged on body rear portion and rolling stay cord vertically is hinged on the body front end and fixes a pull bar 8 are separately fixed on the pull bar 8 and are wrapped in stay cord 7 on the wrench shaft, comprise that also several are installed in the body middle part and are used for the transition wheel 51 (figure shows 2 transition wheels) that stay cord turns to.
The front end of described body also is provided with an extension spring 10, and this extension spring applies a pulling force opposite with the stay cord direction of pull to pull bar.
Described body front end also is provided with a baffle plate 9, and this baffle plate is arranged on key axle 121 next doors; Pull bar 8 drives the key axle and rotates under the stay cord effect, when pull bar 8 was run into baffle plate 9, the direction of key axle promptly was defined (key towards being determined).
Described key axle 121 vertically is hinged on the body front end, and the top of key axle is exposed on the body surface and fixed the label 11 of an indication rotation direction.
The bottom of body also is shaped on a protective block 6, can prevent that key from being clashed into damage.
