Problems solved by technology
The grabbing torque has a decisive relationship with the grabbing rate, and the existing grab cannot determine that the closing torque continues to increase during the closing process of the grab
In the patent document with the publication number CN1381395A, a multi-lobe synchronous hydraulic grab is disclosed. Hinged, the hydraulic cylinder is installed between the upper and lower beams, the jaw plate is both rotating and translational during the closing process, which cannot guarantee the continuous increase of the grabbing torque

Embodiment Construction
[0010] The present invention is described in more detail below in conjunction with accompanying drawing example:
[0011] combine figure 1 and figure 2 In this embodiment, the jaw plate 1 is hinged on the upper beam 3, which is hinged with the internal connecting rod 2 of the grab bucket, the connecting rod 2 is hinged with the lower beam 6, the lower beam 6 is fixedly connected with the piston 5, and the cylinder barrel 4 is fixed on the upper beam 3 Up, the telescopic movement of the piston 5 drives the lower beam 6 to move up and down, and the lower beam 6 drives the jaw plate 1 to rotate through the connecting rod 2 .
[0012] During the closing process of the grab bucket, the closing torque of the jaw plate gradually increases. When closing, the angle between the connecting rod 2 and the jaw plate 1 is 90 degrees, and the maximum closing torque is achieved.
[0013] The jaw plate 1 is hinged on the upper beam 3 and is hinged with the internal connecting rod 2 of the gr...

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 [0001] The invention relates to a material grabbing device, in particular to a moment-increasing inline multi-jaw hydraulic grab. (2) Background technology [0002] At present, the inspection well cleaning method widely used in China is still manual cleaning, and urban drainage pipes are often blocked and difficult to clean up, which brings a lot of inconvenience to people's lives, affects the city's appearance and economic development, and seriously Even in the flood season, it will also affect the smooth progress of urban flood control work. Drainage pipeline operation is an operation in a confined space. The decomposition of organic matter in the accumulated water in the pipeline and the discharge of industrial wastewater will produce methane, poisonous gas and other toxic gases. The cleaning work may bring life danger to workers. restrictions, and there is a hidden danger of explosion. In recent years, some inspection well dredging devices have appe...
