Abstract
The utility model relates to an expansion excavating skip in manhole in a well. Two rocking arms are hinged and connected to the lower end of an outer sleeve barrel, and the lower ends of the rocking arms are hinged and connected with two excavating skips which are hinged and connected with central push rods by two connecting rods. The long hole of the push rod is connected with the long hole of the rocking arm by a central shaft, and the push rod is moved to make the excavating skip expanded and closed. The dredging problems of small well opening and big well bottom can be solved by the utility model, the sludge in a dung well and at the bottom of a sewerage well can be cleaned effectively, and the work environment for workers is improved.
Description
The utility model relates to a kind of grabbing excavator bucket device, especially can adapt to the big change excrement well in little bottom suitable for reading, the mud of sink hole, sedimental cleaning.
In the past during environmental sanitation department cleaningization excrement well deposit, need people's cleaning in the well down, work under bad environment, dangerous big.At present, the grab bucket of known goods bulk be crane drive grab bucket do about, all around moves, and has a little reductor to make in grab bucket, grab bucket is opened, is drawn, finishes the mobile action of putting down of picking up of material.If adopt this grab bucket, the deposit of cleaningization excrement well can only be removed the deposit of the area littler than well head, can not satisfy the requirement of cleaning.
The purpose of this utility model is to provide a kind of grabbing excavator bucket, and it can draw the deposit greater than well head area bottom in, proposes to reach the purpose of the deposit thing that thoroughly opens a hole outside the well.
The utility model is achieved in that in the outer sleeve lower end and is hinged two rocking arms, and the lower end of rocking arm is hinged two grabbing excavator buckets, and two grabbing excavator buckets are hinged with two connecting rods and center tappet, and the slotted hole of tappet is connected with jackshaft with the slotted hole of rocking arm.When tappet moved down, the grabbing excavator bucket servo-actuated was opened.When tappet continues to move down, drive jackshaft and move down and stir the outside herringbone of two rocking arms fork, do to grab and dig preparation.When integral body drops to contact during the scope of operation, handle again tappet move up drive grabbing excavator bucket, rocking arm draws in, proposes well head.Remove well head, handle tappet and move down grabbing excavator bucket is opened, draw off thing in the bucket, on move tappet, grabbing excavator bucket is drawn in, finish once to grab and dig action.Whole can the rotation in the scope that is not less than 180 degree can be finished greater than the down-hole of well head area and be dug purpose clearly.
Owing to adopt such scheme, can replace manually going into the well and dig clearly and the change excrement well that other machinery can't be finished and the desilting work of sink hole, improved operating environment.
Embodiment specifically further specifies the utility model below in conjunction with accompanying drawing.
Among the figure 1, change excrement well well head 2, outer sleeve 3, tappet 4, jackshaft 5, go up hinge 6, rocking arm 7, connecting rod 8, "down hinge 9, grabbing excavator bucket
In the figure illustrated embodiment, outer sleeve (2) lower end is provided with two pairs of fraisings, goes up hinge (5) with two and is connected with the fraising of going up of two rocking arms (6).The following fraising of two rocking arms (6) is connected with the outer fraising of two "down hinges (8) with two grabbing excavator buckets (9).The connecting rod fraising of two grabbing excavator buckets (9) is hinged with an end of connecting rod (7), and the following fraising of the other end of connecting rod (7) and tappet (3) is hinged.The jackshaft slotted hole of one slotted hole and two rocking arms is arranged on the top of the following fraising of tappet (3), connect with jackshaft (4).The upper end of outer sleeve (2) is connected with the upper end of a double acting oil cylinder with tappet (3), and control tappet (3) moves up and down in outer sleeve (2), forms one complete, the interior expanded type grabbing excavator bucket of well.
Its use operation process is such: the upper end of expanded type grabbing excavator bucket in well, the wire rope of connection hoisting mechanism.The operator handles the top of hoisting mechanism with winching to of expanded type grabbing excavator bucket excrement well well head (1) in the well.Behind the entering excrement well of lower end, operating hydraulically operated handle moves down tappet (3) and drives grabbing excavator bucket (9) rocking arm (6) fork.Two handle hoisting mechanism makes grabbing excavator bucket (9) contact work plane.Operating hydraulically operated handle makes on the tappet (3) and moves, and can drive grabbing excavator bucket (9) rocking arm (6) and draw in to the centre, and the deposit of changing in the excrement well enters in the grabbing excavator bucket (9) immediately.After two buckets close up, handle hoisting mechanism, propose to move on well head side or the automobile expanded type grabbing excavator bucket in the well.Operating hydraulically operated handle make tappet (3) move down grabbing excavator bucket (9) open can draw off the bucket in thing, the reversible control hydraulic handle makes grabbing excavator bucket (9) return, has finished a working programme.Rotate the position of expanded type grabbing excavator bucket in the well, carry out above-mentioned working cycles, can the deposit of changing in the excrement well is peace and quiet.
Claims (2)
1, expanded type grabbing excavator bucket in a kind of well, it is characterized in that: be hinged two rocking arms in the outer sleeve lower end, the lower end of rocking arm is hinged two grabbing excavator buckets, and two grabbing excavator buckets are hinged with two connecting rods and center tappet, and the slotted hole of tappet is connected with jackshaft with the slotted hole of rocking arm.
2, grabbing excavator bucket according to claim 1 is characterized in that: a slotted hole is arranged at the top in the following fraising of tappet.
