Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention will be further described with reference to the drawings and the specific embodiments.

The object is handled to this example for the large-scale grid canal that intakes of sewage treatment plant, nevertheless the utility model discloses a protection scope is not restricted to this example, according to parameters such as sewage treatment capacity, sewage medium, the quality of water of intaking earlier, confirms pump station intake canal structure size. Including channel quantity, grid width, grid clearance, channel depth, grid water inlet and outlet level marks and the like. The designer makes a specific equipment arrangement scheme of the anti-tipping grab bucket grating according to technological parameters, and the lifting cut-in position size of the grab bucket comprising the gantry guide rail frame, the underwater grating and the opening and closing grab bucket ensures that the design and field installation size is correct.

As shown in fig. 1, fig. 2, fig. 3, fig. 4 and fig. 5, the technical solution adopted by the present invention for solving the technical problem is: a novel anti-tipping grab bucket grid comprises a gantry guide rail frame 100, an opening and closing grab bucket 110, a driving trolley 120, a slag blocking plate 130, a guide grid 140 and an underwater grid 150.

The open-close grab bucket 110 in the anti-tipping grab bucket grid consists of a tooth rake 200, a vertical bracket 210, a roller 220, a transverse shaft 230, a hoisting steel wire rope 240, a lifting lug 250, a piston oil cylinder 260, a hinge seat 270 and a grab rake 280.

The utility model discloses the theory of operation does: the anti-overturning grab bucket grating is a driving trolley 120 moving on a gantry guide rail frame 100, the driving trolley 120 drives a hoisting steel wire rope 240 to perform downward opening or upward closing actions on an opening and closing grab bucket 110, every channel is immediately transferred to a storage hopper to be removed after every channel is raked and cleaned, then the next channel raked and cleaned procedure is repeatedly performed, and the anti-overturning grab bucket grating has the functions of wide operation area and capability of cleaning floating garbage of multi-channel gratings by one machine.

The anti-tipping grab bucket grating is used for the multi-ditch distribution grating, after the grab bucket grating decontaminates the grating of one ditch, the grab bucket grating moves to another ditch, and the decontamination is continued until the decontamination of the grating surfaces of all the ditch gratings is completed.

When the driving trolley 120 in the anti-tipping grab bucket grid horizontally moves on the gantry guide rail frame 100 and reaches a sewage raking point, the limiting inductor can be triggered to accurately position; the driving trolley 120 can respectively touch the cam limit device and the stroke limit sensor when the opening and closing grab bucket 110 is hoisted and lifted.

The lifting lugs 250 on the opening and closing grab bucket 110 are suspended on a winch of the driving trolley 120 through a lifting steel wire rope 240, the pressure oil pipe of the piston oil cylinder 260 on the opening and closing grab bucket 110 is telescopically retracted and extended by a spring oil pipe winding drum of the driving trolley 120, and the driving trolley 120 can horizontally run in the longitudinal direction of the gantry guide rail frame 100 through the driving of a walking motor.

When the opening and closing grab bucket 110 is lowered down from the hoisting steel wire rope 240, the rake 280 is in an open state by starting the contraction of the piston oil cylinder 260; when the open-close grab bucket 110 descends to the bottom of the channel, the extension of the piston cylinder 260 is started to enable the grab harrow 280 to be in a closed state, so that all the blocked garbage on the grid surface in the channel and the garbage deposited on the bottom of the channel can be captured and fished.

When the opening and closing grab bucket 110 is used for grabbing dirt downwards, the toothed harrow 200 on the opening and closing grab bucket can be tightly meshed with the guide grid 140 and the underwater grid 150, so that the hair-like dirt and entanglement around the grids can be effectively removed.

The lifting lugs 250 on the opening and closing grab bucket 110 are respectively provided with three lifting hole positions, and the lifting gravity center of the opening and closing grab bucket 110 and the position of a grab bucket water falling point can be controlled.

The opening and closing grab bucket 110 has an anti-tipping function, and during the downward movement of the opening rake, once the grid teeth are inserted into the grid and meet the garbage blockage, the larger overall balance weight of the tooth rake 200, the vertical bracket 210, the roller 220 and the transverse shaft 230 inside the lifting steel wire rope 240 can be used for resisting gravity and resistance, and the garbage blockage can be shoveled and smoothly downward by the self weight inside the grab rake. When the self weight of the inner side of the rake is less than the resistance, the rake in the rake opening state can not tip over outwards when the rake is static and difficult to move downwards due to the effect of the inward bending moment generated by the counterweight on the inner side of the rake.

When the opening and closing grab bucket 110 is blocked in a downward direction, once the hoisting steel wire ropes 240 on the two sides are in a rope loosening phenomenon, the rope loosening limiting sensing device is immediately touched to stop.

The utility model discloses an anti-tipping grab bucket grid has that design structure performance is good, strong adaptability, the handling capacity of decontaminating is big, the grab and drag for the degree of depth big, operation area wide, degree of automation is high, operational environment is good and advantages such as long service life, has extensive engineering application and worth.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to let the technical personnel in the field understand the contents of the present invention and implement the present invention, and the protection scope of the present invention can not be limited thereby, and all equivalent changes or modifications made according to the spirit of the present invention should be covered in the protection scope of the present invention.
