Embodiment Construction
[0011] Lever body 2, pillar 4, base 5 are made of steel pipes. There is a hole at the front end of the bar body 2 . The front and rear tie bars 3 are made of round steel. Hanging chain 6 buy commercially available iron chains. Cover hook 7 is refitted with hanging chain 6 with existing cover hook and links to each other.
[0012] The body 9 is made of a steel pipe just inserted into the bar body 2; the C-shaped bayonet root formed by welding with the factory letter plate 10 is covered with a plastic sleeve, and the friction force generated by inserting the bar body 2 is fixed in the bar body 2, The force cannot be pulled out. Factory character plate 10 is made of flat steel. Steel parts are hot-dip galvanized or painted.

The invention relates to a prying and lifting device for a cable inspection well cover, and belongs to the technical field of power transmission and distribution engineering. The prying and lifting device consists of a prying bar 1 and a lifting handle 8. The lifting handle 8 is inserted in the rod body 2 of the prying bar 1. The prying bar 1 consists of the rod body 2, a tie bar 3, a pillar 4, a base 5, a lifting chain 6 and a cover hook 7. The front end of the rod body 2 is hinged to the lifting chain 6, and the lifting chain 6 is hinged to the cover hook 7. The support pillar 4 is welded at the front part of the rod body 2. The base 5 vertically staggered with the rod body 2 is welded at the bottom of the support pillar 4. The tie bar 3 is welded between the base 5 and the rod body 2 in front of and at the back of the support pillar 4. The lifting handle 8 is formed by welding a handle body 9 and an inverted L-shaped plate 10. The cover hook 7 is inserted in a inspection well cover hole, the base 5 is taken as a supporting point, and the inspection well cover is lifted by pressing the tail end of the rod body 2 downwards; the inspection well cover is clamped by a bayonet of the lifting handle 8, and the lifting handle 8 is hold with hands to pull up and turn over the inspection well cover. The cable inspection well cover is easily opened, so that the device is safe, reliability and high in work efficiency. The prying and lifting device is used for opening inspection well covers such as cable inspection well covers.
Description
technical field [0001] Transmission and distribution engineering. Background technique [0002] The cable trench inspection well cover for underground power transmission is large and heavy, and is hinged with the well circle. After a period of time, the gap between the manhole cover and the manhole circle is filled with soil and rusted, so it takes a lot of effort to open it. Contents of the invention [0003] The technical problem to be solved by the cable manhole cover prying device is to easily open the cable manhole cover. [0004] The technical scheme that adopts is: adopt the crowbar of lever principle to lift the handle to open and overturn the well cover. [0005] Cable manhole cover prying device ( figure 1 ) is made up of crowbar 1, lifting handle 8. Lifting handle 8 is inserted in the bar body 2 of crowbar 1 at ordinary times. Crowbar 1 is made up of bar body 2, tie bar 3, pillar 4, base 5, hanging chain 6, cover hook 7. The front end of the bar body 2 is ...
