Description

Inspection shaft silt clearance instrument

Technical Field

The invention relates to the field of dredging tools, in particular to an inspection well sludge cleaning tool.

Background

The inspection well is used at the turning, branching, falling and other positions of a drainage pipeline so as to be convenient for inspection and dredging of a vertical shaft, and the inspection well dredging plays a vital role in dredging and draining the pipeline of the whole city. Long-term stable dredging can prevent urban waterlogging. However, a lot of sundries such as stones, cement mortar, silt and the like brought to the whole underground drainage channel of a city by heavy rain and domestic garbage such as plastic bags and the like are not exhausted, the sundries are precipitated in the inspection well, if the silt and the garbage are not removed in time, the inspection well is blocked, sanitation is affected, and the smooth operation of city flood prevention work is affected in the flood season, so that the city is very prone to waterlogging. Nowadays, the desilting work of the inspection well becomes an important work which is not neglected in the drainage department.

The dredging vehicle is one kind of special vehicle, and the existing dredging vehicle uses a manually operated grab bucket type dredging vehicle, and is characterized by simple structure and capability of simply replacing manual dredging; however, since an operator cannot directly observe the conditions in the inspection well and needs to guide the operation by other people, a visual error exists, and the problem of poor positioning precision exists in the inspection well dredging process, so that the grab bucket needs to be adjusted repeatedly every time the operator grabs the inspection well, the stability of the action of the grab bucket is poor, meanwhile, the dredging vehicle is large in size, when the inspection well near a road is cleaned, the influence on traffic is large, the engine is required to drive the grab bucket of the dredging vehicle to provide power, not only is petroleum resources consumed, but also tail gas of the dredging vehicle can harm urban environment, the dredging vehicle is expensive, professional operators are required, and the cost for cleaning the inspection well by the dredging vehicle is high, so that the inspection well cleaning method widely used in China still can be manually cleaned at present.

Inspection shaft clearance belongs to airtight space operation, and the organic matter of inspection shaft ponding is decomposed and industrial waste water discharges and can make gas that marsh gas, poison gas etc. have harm store up, and the operational environment is abominable, and is unsuitable for the workman directly to get into the inspection shaft and draw and dig, and under the general condition, the clearance workman can prepare long handle silt bag, long handle stick fork, the curved ladybug of long handle of instrument such as mutually supporting and draw and dig, wastes time and energy, and is dirty again tired, and inefficiency, and it is very inconvenient to operate.

The patent with the application number 201410242587.7 discloses a sludge grab bucket consisting of a first grab bucket, a second grab bucket, a mounting seat, an operating rod, a handle positioning mechanism, a pull rod and a connecting seat, as shown in a drawing 6, the grab bucket mechanism has certain technical defects in design and cannot completely improve the problems of labor waste and low efficiency when an environmental sanitation worker cleans a manhole at the present stage, and the problems that ① needs to tightly hold the operating rod (5) or a bending part (5.1) of the operating rod when the worker operates the sludge grab bucket, the other hand pulls the handle (7) upwards to pull the handle (7) to a proper position after the handle (7) is pulled, the two hands cannot release the handle, an arc-shaped support rod (8) does not have an automatic closing function, so that the second teeth (8.1) on the arc-shaped support rod (8) can only be clamped with first teeth (9.1) on a support (9) by the other worker when the handle swings into a swinging rod, the handle (7) to be opened with a limited swinging angle of the handle (6) and the handle (7), the handle (7) is not easy to move, the handle is not easy to move, namely, the handle is a swinging angle of the handle (7) and the handle (6) is larger than the limit, the height of the handle (7) when the handle is larger than the handle, the handle (6), the handle (7) of the handle (6), the handle (7) is larger than the handle, the handle is larger than the handle, the handle swinging angle of the handle (7) of the handle, the handle (7) of the handle (7), the handle (7) of the handle is larger, the handle is larger value of the handle, the handle is larger, the handle is larger, the handle is larger handle, the handle is larger, the handle is larger, the handle is the handle, the handle.

The embodiment of the invention comprises the following steps:

when the inspection well needs to be desilted, firstly, the inspection well cover is opened, the distribution condition of sludge in the inspection well is observed, then, the left handle 1 and the right handle 2 are mutually closed, the hook 2.1 of the right handle 2 is inserted into the rectangular hole of the left handle 1, at the moment, three bucket flaps (8.1, 8.2 and 8.3) are closed together, then, the lower end of the grab bucket extends into the bottom of the inspection well, then, the clamping handle 10 in the left handle 1 is pulled upwards, then, the left handle 1 and the right handle 2 are opened towards two sides, in the process, the outer rod 5 is pulled upwards by two upper supporting rods (3.1 and 3.2), the grab bucket is gradually opened, the grab bucket is downwards inserted into the sludge at the bottom of the inspection well, the left handle 1 and the right handle 2 are gradually closed, in the process, the outer rod 5 is gradually moved upwards, the three bucket flaps (8.1, 8.2 and 8.3) are gradually closed and shovel the sludge into the grab bucket, after the hook 2.1 on the right handle 2 is inserted into the rectangular hole of the left handle 1, the couple latch 10.1 of card handle 10 lower extreme blocks couple 2.1, makes left handle 1 and right handle 2 can not part from each other, later carries and draws left handle 1, right handle 2 and outer pole 5 and pull out the inspection shaft with the grab bucket, places the grab bucket on fortune dirty car after, upwards pulls card handle 10 to couple latch 10.1 is let go of couple 2.1, opens left handle 1 and right handle 2 to both sides afterwards, makes three fill lamella 10 alternate segregation, thereby opens the grab bucket, places the mud in the grab bucket in the clearance dirty car, repeats above-mentioned operation process, until the silt clean up in the inspection shaft.

The left handle 1 and the right handle 2 are made of materials with certain elasticity, when the left handle 1 and the right handle 2 are close to each other, after the grab bucket is closed, the three bucket flaps (8.1, 8.2 and 8.3) are mutually depended and pressed, the outer rod 5 cannot move upwards continuously, at the moment, the hook 2.1 of the right handle 2 is required not to be inserted into the rectangular hole of the left handle 1, therefore, the left handle 1 and the right handle 2 need to be closed continuously, in the process, the left handle 1 and the right handle 2 are elastically deformed until the hook of the right handle 2 is inserted into the rectangular hole of the left handle 1 and clamped by the hook clamping teeth 10.1, the left handle 1 and the right handle 2 cannot be separated, the grab bucket can be tightly closed by the elasticity generated by the deformation of the two handles (1 and 2), and therefore, the phenomenon that gaps are generated between the three bucket flaps (8.1, 8.2 and 8.3) and sludge automatically flows down from the gaps is avoided, and the operation space is.
