Abstract
The utility model belongs to the mechanical screw technology, aims to provide machinery which changes pure manual opening of a well lid into semi-automatic opening to reduce the labor intensity of workers, improve the work efficiency and prolong the service life of the well lid, and provides a spiral lifting device for a manhole cover. The spiral lifting device is mainly characterized in that two A-type supports are respectively mounted at the two ends of a main cross beam, a nut and a lifting screw rod are mounted in the middle of the main cross beam, meanwhile, a lifting handle is fixed to the upper end of the lifting screw rod, the lower end of the lifting screw rod is sleeved with a small cross beam and a stop block, finally, the two ends of the small cross beam are sleeved with lifting hooks, and the lifting hooks are connected with a well lid. The spiral lifting device is mainly used for opening a manhole cover, because urban grounds are bestrewn with various well lids, however, most of the well lids are difficult to open due to natural environmental factors, inspection and repair are troublesome and inconvenient, and even loss is caused.
Description
Technical field:
The utility model belongs to mechanical spiral lift technique.
Background technology:
Now countless inspection well covers on ground, cities and towns, because sand and dust sleet and the reason such as freezing are difficult to while causing maintenance open.Existing unlatching way mainly contains: hook hook, crowbar sled, iron hammer strike and the pick handwork such as not.Its labour intensity is large, efficiency low and service life of greatly reducing well lid.
Summary of the invention:
The purpose of this utility model is: open manhole cover is manually changed over to semi-automatic mechanization from pure.Thereby alleviate people's labour intensity, increase work efficiency and extend service life of well lid.
The technical solution of the utility model is, inspection well cover screw lifting device, it comprises a lifting hook, it is characterized in that: its two ends of a main beam (4) are provided with A type support (5), a nut (3) and corresponding lifting screw (2) are fixed in middle part, on the top of this lifting screw (2), lifting handle (1) is installed, a needle beam (6) and block (8) installed in bottom, on needle beam (6), mount with well lid hole hook with together with lifting hook (7).Each part mentioned above forms inspection well cover screw lifting falling unit jointly.This device is detouchable, Assembling when application.Assemble and be completely integrally connected with the well lid access opening that is unlocked promoting hook (7), then both hands rotate lifting handle (1) open manhole cover.
The beneficial effect of the utility model contrast background technology:
1 is laborsaving.Pure artificial with machinery replacement, the diameter dimension that particularly increases lifting handle (1) can be more laborsaving.
2 savings of labor.Pure artificial with machinery replacement, the large speed of power saves time soon.
3 extend the well lid life-span.Pure artificial, evenly afterburning with machinery replacement, reduce the destruction to well lid.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
(1) lifting handle, (2) lifting screw, (3) nut, (4) main beam, (5) A type support, (6) needle beam, (7) lifting hook, (8) block.
Detailed description of the invention:
Existing inspection well cover geomery is all different, existing taking two open holes as example.Measure well lid size and determine the scantling of structure of main beam (4) and needle beam (6).Given hoisting depth is to determine the height of A type support (5).Determine diameter and the size of lifting screw (2) and lifting hook (7) according to local natural environment and climate condition.The material of main beam (4) A type support (5) can be pipe or section bar, the material requirements high strength of lifting hook (7), and good rigidly is on-deformable.The screw thread of lifting screw (2) and nut (3) preferably adopts Acme thread, gains in strength.This is wherein except A type support (5) employing is fixedly connected with, and all the other are all designed and manufactured into detouchable and are flexibly connected convenient mobile.
