Description
Technical field
The utility model relates to a kind of lever type manhole cover, cover plate hangs the instrument of moving.
Background technology
In recent years, along with the acceleration of various places urbanization process, a large amount of layings of the pipe network such as power communication, water supply and sewage, gas transmission, build the well lid, the cover plate that employ various material.In its use procedure, there is various problem: the cement cover board weight had is too heavy badly to be opened; Some well lids are not opened for a long time, and fill up foreign material around and be difficult to open, this seems a simple procedure to make open manhole cover, becomes the large problem affecting maintenance and inspection work efficiency.Traditional cover opening tool is cleek, pickax and sledgehammer, is commonly called as " three-major-items ", and the well lid of unlatching difficulty, cover plate often use sledgehammer destructiveness to open, and cause well lid damage or scrap.Therefore, we develop a kind of simple to operate, sturdy and durable, the Multifunctional well cover of safety of operation, cover plate and hang the instrument of moving, and can not only alleviate the labour intensity of operating personal, increase work efficiency, and not damage well lid, cover plate, reduce the service expenditure changed.
Summary of the invention
The purpose of this utility model is to provide a kind of lever type manhole cover, cover plate hangs the instrument of moving, and overcomes the defect that above-mentioned prior art exists.
The technical solution of the utility model is achieved in the following ways:
The utility model comprises lever, lever connecting seat, support, lifting rope, suspension hook and two-point form arresting agency or four-point arresting agency, it is characterized in that: cradle top and lever connecting seat are weldingly connected, lever connecting seat is nested with lever and is connected, lever is linked by lifting rope and hook, link up with and the hanging a cutting ferrule or hang a snap ring and be connected of two-point form arresting agency or four-point arresting agency, formation lever type manhole cover, cover plate hang the instrument of moving.
Two-point form arresting agency comprises and hangs a cutting ferrule, grapple suspension ring and hang cylinder, hang a cutting ferrule two ends and be provided with cutting ferrule, be stuck with sleeve two ends, grapple suspension ring are set to two symmetrical equicrural triangle suspension ring, be located on and hang in the centre hole of cylinder, grapple is set to symmetrical two, and upper end is provided with the collar, be nested with grapple suspension ring, lower end is provided with 90 degree or be less than the grapple of 90 degree.
Four-point arresting agency comprise hang a suspension ring, hang cylinder, grapple frame cutting ferrule, grapple frame and grapple, hang a suspension ring and be set to equicrural triangle, be nested with the centre hole hanging cylinder, grapple frame cutting ferrule is set to symmetrical two, and respective two ends are provided with cutting ferrule, and middle part is placed in the centre hole hanging cylinder, the card sleeve clamp at two ends is in grapple frame both sides, grapple erection is two symmetrical pipes, and respective two ends are provided with grapple hole, and hook is connected with grapple frame nut through grapple hole.
Support is set to four leg formulas or the three leg formulas of leg appearance etc., upper end with link with disk separately, bottom is provided with one and moves back the cutting ferrule be nested separately with three legs.
Lever connecting seat comprises drum type brake permanent seat and lever socket, and drum type brake permanent seat lower weld is on the disk of support, and top is provided with openning, lever socket top is provided with sleeve pipe, middle part is provided with rotating shaft, and bottom is provided with rotating disk, and the diameter of rotating disk is greater than the width of openning.
The utility model has the advantages that:
1, quick open manhole cover, cover plate, increase work efficiency.Be difficult to well lid, the cover plate opened more in the past, used " old three samples ", about 30 minutes/consuming time of 3 people.And use Multifunction lever formula well lid, cover plate hangs the instrument of moving, 2 people operation, only needs about 3 minutes.
2, after open manhole cover, cover plate, conveniently move.Traditional " old three samples ", after levering up well lid, cover plate, move inconvenience to side, waste time and energy, too near with operating personal, easy presser feet.And use Multifunction lever formula well lid, cover plate hangs the instrument of moving, and does not have operating personal near well lid, cover plate, the rotating shaft on A-frame can make 360 ° of angles about lever horizontal surface rotate, and makes it easily go to correct position and puts down.
3, improve economic benefit, some are difficult to well lid, the cover plate opened, use " old three samples ", well lid, cover plate cracky, or damage, and can not use.And use Multifunction lever formula well lid, cover plate hangs the instrument of moving, well lid, cover plate are not easily damaged, extend well lid, cover plate tenure of use.

Detailed description of the invention
For disclosing the technical solution of the utility model further, elaborated by embodiment below in conjunction with Figure of description:
The utility model comprises lever 3, lever connecting seat 4, support 5, lifting rope 2, suspension hook 1 and two-point form arresting agency or four-point arresting agency, it is characterized in that: support 5 top and lever connecting seat 4 are weldingly connected, lever connecting seat is nested with lever 3 and is connected, lever is linked by lifting rope 2 and suspension hook 1, link up with and the hanging a cutting ferrule or hang a snap ring and be connected of two-point form arresting agency or four-point arresting agency, formation lever type manhole cover, cover plate hang the instrument of moving.During use, first install and fix support 5 assembly, then select suitable two-point form arresting agency or four-point arresting agency according to dissimilar well lid, cover plate.
Grapple 1, grab in the space on well lid hole or cover plate limit, if the space on well lid hole or cover plate limit is blocked by foreign material, the tip of available lever 2 is chiseled, clean out, then lever 3 is penetrated in the sleeve pipe of lever connecting seat 4, regulate fulcrum, the tip of presses lever 3 levers up well lid or cover plate, to sling well lid or cover plate with two-point form arresting agency or four-point arresting agency again, then turn to correct position to the left or to the right, put down well lid or cover plate gently, complete whole operation.When with four-point arresting agency, as shown in Figure 2, hang a suspension ring 7 with suspension hook, the cover plate not hanging nose sling remove by hanging cylinder 8, grapple cutting ferrule 9, grapple frame 10 and grapple 11, the maintenance work of next program can be carried out.
