Abstract
The invention provides a gripping device of a cleaning machine of a city inspection shaft. The gripping device consists of a jaw plate (1), a connecting rod (2), an upper crossbeam (3), a hydraulic cylinder (4), a piston (5) and a lower crossbeam (6); and the gripping device is characterized in that the jaw plate (1) is hinged on the upper crossbeam (3), the jaw plate (1) is further hinged with the connecting rod (2) positioned in a grab, the connecting rod (2) is hinged with the lower crossbeam (6), the lower crossbeam (6) is fixedly linked with the piston (5), and an oil cylinder (4) is fixed on the upper crossbeam (3). The gripping device designs a torque-increasing inner-linked type multi-jaw-plate hydraulic grab, the gripping torque of the grab can be continuously increased during theclosing process, and the inner-linked structure can effectively reduce the dimension, reduce the self-weight of the grab, solve the conflict between high gripping efficiency and small dimension in limited space, grip bulk materials of sludge, ash slag, bricks, billets, ropes and the like, have good raking property and grip silt and dry soil, thereby having versatility, high working efficiency, simple and reliable structure, simple operation and low maintenance.
Description
(1) technical field
What the present invention relates to is a kind of extracting material device, is specifically related to a kind of many jaws of square intraconnected hydraulic grab that increases.
(2) background technology
Domestic widely used inspection shaft is drawn method clearly still for manually drawing clearly at present, urban discharging pipeline often occurs stopping up and the phenomenon of easy to clean not, bring many inconvenience for the people's life, influenced the city look and feel and the expanding economy in city, serious is also to have influence on carrying out smoothly of city work of flood prevention in flood season.The drainage pipe operation belongs to Working in confined space, organic matter decomposition in the water accumulation of pipeline and industrial wastewater enter toxic gases such as meeting generation biogas, poison gas and accumulate, cleaning work may bring life danger to the workman, operating environment is abominable, efficient is low, limited by natural environment, and also have the hidden danger of blast.Some inspection shaft Accrete clearing devices have appearred in recent years, utilize grab bucket to grasp inspection shaft mud, but because of grab bucket dischargeable capacity little (being subjected to the inspection shaft spatial constraints), grab bucket structure and the design of Hubei Province plate are unreasonable, grab bucket rake collection property is bad, and lifting force is low, inefficiency, the overall structure installation dimension is big, so still can not satisfy the requirement that promotes the popularization use of large, medium and small city.
Be extensive use of the various materials of cargo handling with grabs at present, the grab bucket working space is also unrestricted, and grab bucket can be determined appearance and size arbitrarily, will obtain reasonable snatch rate and just produce contradiction with grab bucket appearance and size in the confined space, but take intraconnected design head it off.Grasping moment and snatch rate has decisive sexual intercourse, and existing grab bucket can not determine that the closed moment of grab bucket closing course continues to increase.Publication number is in the patent document of CN1381395A, a kind of multi flap synchronous hydraulic grab bucket is disclosed, its technical scheme is that the strut upper end is hinged with deck beam, the outer middle side part of strut lower end and jaw is hinged, jaw top and lower transverse beam are hinged, hydraulic cylinder is installed between lower and upper cross-member, had not only been rotated but also translation in the jaw closing course, can not guarantee to grasp moment and continue to increase.
(3) summary of the invention
The object of the present invention is to provide a kind of extracting moment that can continue to increase; Can be little in deadweight, realize under the little condition of profile that the city inspection shaft of high snatch rate draws the grabbing device of machine clearly.
The object of the present invention is achieved like this:
The present invention is made up of Hubei Province plate 1, connecting rod 2, top rail 3, hydraulic cylinder 4 and piston 5 and lower transverse beam 6; Jaw 1 is hinged on the top rail 3, jaw 1 is also hinged with the connecting rod 2 that is positioned at grab bucket inside, connecting rod 2 is hinged with lower transverse beam 6, lower transverse beam 6 is fixedly connected with piston 5, cylinder tube 4 is fixed on the top rail 3, drive lower transverse beam 6 by piston 5 stretching motions and move up and down, lower transverse beam 6 drives jaw 1 by connecting rod 2 and rotates; In the grab bucket closing course, Hubei Province plate 1 increases gradually with connecting rod 2 angles, and connecting rod 2 is 90 degree with Hubei Province plate 1 angle when closed.
Designed many jaws of the square intraconnected hydraulic grab that increases of the present invention, grasp the sustainable increase of moment in the grab bucket closing course, the intraconnected structure effectively reduces appearance and size, reduce the grab bucket deadweight, in the confined space, can solve high efficient and the little appearance and size contradiction of grasping, of many uses, high efficiency, simple and reliable for structure, easy and simple to handle, keep in repair cheap.
(4) description of drawings
Fig. 1 is an overall structure of the present invention;
Fig. 2 is the inner connection diagram of grab bucket;
(5) specific embodiment
For example the present invention is done description in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1 and Fig. 2, present embodiment is hinged on the top rail 3 by jaw 1, hinged with grab bucket inner link 2, connecting rod 2 is hinged with lower transverse beam 6, lower transverse beam 6 is fixedly connected with piston 5, cylinder tube 4 is fixed on the top rail 3, and piston 5 stretching motions drive lower transverse beam 6 and move up and down, and lower transverse beam 6 drives jaw 1 by connecting rod 2 and rotates.
In the grab bucket closing course, Hubei Province plate closing moment increases gradually, and connecting rod 2 is 90 degree with Hubei Province plate 1 angle when closed, realizes closed moment maximum.
Jaw 1 is hinged on the top rail 3, and hinged with grab bucket inner link 2, it is inner that connecting rod 2 is positioned at grab bucket, can solve the contradiction between maximum appearance and size of grab bucket and the volume like this in limited working space.
In the grab bucket closing course, connecting rod 2 increases gradually with Hubei Province plate 1 angle, and Hubei Province plate closing moment increases gradually, and the closed back link 2 of grabbing bucket is 90 degree with Hubei Province plate (1) angle, and closed moment maximum, closed moment meet extracting material process, can obtain high snatch rate.
When grab bucket was opened fully, plate 1 tip in Hubei Province was vertical with horizontal plane, and the initial insertion of the grab bucket material degree of depth is good, can obtain high snatch rate with little grab bucket deadweight.
Claims (1)
1, a kind of city inspection shaft is drawn the grabbing device of machine clearly, is made up of Hubei Province plate (1), connecting rod (2), top rail (3), hydraulic cylinder (4) and piston (5) and lower transverse beam (6); It is characterized in that: jaw (1) is hinged on the top rail (3), jaw (1) is also hinged with the connecting rod (2) that is positioned at grab bucket inside, connecting rod (2) is hinged with lower transverse beam (6), lower transverse beam (6) is fixedly connected with piston (5), cylinder tube (4) is fixed on the top rail (3), drive lower transverse beam (6) by piston (5) stretching motion and move up and down, lower transverse beam (6) drives jaw (1) by connecting rod (2) and rotates; In the grab bucket closing course, Hubei Province plate (1) increases gradually with connecting rod (2) angle, and connecting rod (2) is 90 degree with Hubei Province plate (1) angle when closed.
