Description

Technical Field

[0001] The utility model belongs to the technical field of sludge dredging in the bottom bin sedimentation tank, and particularly relates to a sludge dredging device for the bottom bin sedimentation tank. Background Art

[0002] The connecting roadway of the main shaft bottom bin is the horizontal roadway connecting the lowest point of the main shaft shaft, which is mainly used for cleaning the coal scattered in the main shaft and pumping out the shaft water spray to prevent accidents such as clogging of the eyes and flooding caused by the accumulation of coal and water. Specifically, the coal scattered during the loading and unloading of the main shaft enters the bottom of the shaft under the action of gravity, and the water flow in the shaft flows into the bottom bin sedimentation tank through the hopper opening.

[0003] Therefore, a large amount of coal and sludge precipitate in the bottom bin sedimentation tank to form sludge, resulting in serious siltation of the bottom bin sedimentation tank, and further leading to a significant reduction in the water storage capacity.

[0004] Therefore, the sludge in the bottom bin sedimentation tank needs to be cleaned regularly. The current cleaning method is the manual cleaning method, that is, manually using a shovel to dig the accumulated coal in the sedimentation tank for sedimentation tank sludge dredging. This cleaning method must enter the inside of the sedimentation tank. Affected by the water spray in the main shaft, the accumulated coal in the shaft is prone to the situation of the water and coal flushing into the sedimentation tank, causing safety accidents. Moreover, a large number of people are required for cleaning, the labor intensity is high, and the working environment is poor. This is a major contradiction in the transformation of the current production method of our unit.

[0005] Due to the narrow space where the bottom bin sedimentation tank is located, traditional sludge dredging equipment such as excavators is difficult to enter the operation area for operation. Limited by the geographical space where the bottom bin sedimentation tank is located, the excavator simply cannot operate and can only operate through the above-mentioned manual method.

[0006] The disadvantages of the manual operation method are very obvious and the efficiency is very low. Therefore, in the actual production process, how to adopt a highly flexible sludge dredging device that can efficiently dredge the bottom bin sedimentation tank in a narrow space is of great significance for solving the above-mentioned technical problems existing in the production process.

[0008] To achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A sludge dredging device for the bottom bin sedimentation tank includes a sludge dredging mechanism.

[0015] Preferably, cross beam frames are respectively hinged to the front and rear sides of the bucket;

[0016] A connecting beam is fixedly connected between the cross beam frames, and a pull rod welded to the top position of the connecting beam is fixedly connected to the bottom of the lifting seat.

[0023] The utility model has the following beneficial effects:

[0024] 1. During the implementation process, when the trolley is above the sedimentation tank at the bottom of the pot, the lifting oil cylinder drives the lifting seat to carry the bucket down into the sedimentation tank at the bottom of the pot. At the same time, the first push-pull oil cylinder and the second push-pull oil cylinder push the inner turning bucket. Since the bucket is hinged on the crossbeam frame, the bucket rotates relative to the crossbeam frame, and the rotation direction is to rotate towards each other. During the rotation process, the sludge is shoveled into the bucket. Subsequently, the lifting oil cylinder drives the bucket to rise. At this time, under the push of the pushing hydraulic cylinder, the trolley runs on the track to the outside of the sedimentation tank at the bottom of the pot. Then, the first push-pull oil cylinder and the second push-pull oil cylinder push the bucket to turn outwards until the bucket opens, and thus the sludge in the bucket falls outside the tank. In this way, the sludge in the sedimentation tank at the bottom of the pot can be cleaned in a very flexible manner, and there is no need for manual intervention during the cleaning process. The automatic shoveling of materials is realized by using structures such as the bucket and the hydraulic cylinder. Therefore, the dredging efficiency is very high.

In this way, a trolley with a simple structure and high flexibility can be assembled and welded using waste steel beams in the workshop, and thus the operation in a narrow working environment can be realized to meet the operation requirements.

[0034] Embodiment 1

[0035] As Figures 1 - 3 shown, a silt cleaning device for the bottom bin sedimentation tank includes a silt cleaning mechanism. The silt cleaning mechanism includes a track spanning across the upper end of the bottom bin sedimentation tank. Specifically, two tracks 1 are arranged at intervals in the front and back across the upper position of the bottom bin sedimentation tank. According to the existing conventional track fixing and installation method, both ends of the above track 1 are fixed on the roadway rib.

[0036] At the same time, a trolley 2 rolls on the track 1; the trolley 2 is assembled and connected with a pushing hydraulic cylinder 42. Specifically, the piston rod of the pushing hydraulic cylinder 42 is installed on the trolley 2, and the cylinder barrel of the pushing hydraulic cylinder 42 is fixedly installed on the track 1.

[0037] During the working process, the pushing hydraulic cylinder 42 is used to push the trolley 2 to move back and forth above and outside the bottom bin sedimentation tank.

[0038] The bottom of the above trolley 2 is assembled and connected with a silt cleaning component, and the silt cleaning component includes a lifting hydraulic cylinder 31 vertically arranged downward.

[0039] Specifically, a plunger rod of the lifting oil cylinder 31 is fixedly connected with a lifting seat 32, and a first push-pull oil cylinder 33 and a second push-pull oil cylinder 34 are respectively hinged to two sides of the lifting seat 32. Meanwhile, a bucket 35 is hinged to the plunger rods of the first push-pull oil cylinder 33 and the second push-pull oil cylinder 34 respectively. The bucket 35 is a conventional bucket 35 disclosed in the prior art. The specific hinging method is as follows:

[0040] An upper ear plate is fixedly connected to an outer side wall of the lifting seat 32, a lower ear plate is fixedly connected to the top of the bucket 35, and hinge tongues are respectively fixedly connected to the cylinder barrels and the plunger rods of the first push-pull oil cylinder 33 and the second push-pull oil cylinder 34. The hinge tongues are hinged to the corresponding upper ear plate and lower ear plate through fixing pins.

[0041] Meanwhile, cross beam frames 36 are respectively hinged to the front and rear sides of the bucket 35 (the hinging method is: pins are welded to upper ends of the front and rear side walls of the bucket 35, and the pins are hinged to the cross beam frames 36), and the lifting seat 32 is installed between the cross beam frames 36.

[0042] Specifically, a connecting beam 3611 is fixedly connected between the cross beam frames 36, and a pull rod 361 welded to the top of the connecting beam 3611 is fixedly connected to the bottom of the lifting seat 32.

[0043] During the working process, when the carriage 2 is above the bottom bin sedimentation tank, at this time, the lifting oil cylinder 31 drives the lifting seat 32 to carry the bucket 35 down into the bottom bin sedimentation tank. Meanwhile, the first push-pull oil cylinder 33 and the second push-pull oil cylinder 34 push the inner-inverting bucket 35. Since the bucket 35 is hinged to the cross beam frames 36, the bucket 35 rotates relative to the cross beam frames 36, and the rotation direction is to rotate towards each other. During the rotation process, the sludge is shoveled into the bucket 35. Subsequently, the lifting oil cylinder 31 drives the bucket 35 to rise. At this time, under the push of the pushing hydraulic cylinder 42, the carriage 2 runs on the track 1 to the outside of the bottom bin sedimentation tank. Then, the first push-pull oil cylinder 33 and the second push-pull oil cylinder 34 push the bucket 35 to turn outwards until the bucket 35 is opened, and thus the sludge in the bucket 35 falls outside the tank. In this way, the sludge in the bottom bin sedimentation tank is cleaned in a very flexible manner, and no manual intervention operation is required during the cleaning process. The automatic shoveling of materials is realized by using structures such as the bucket 35 and the hydraulic cylinder. Therefore, the dredging efficiency is very high.

[0044] Embodiment 2

[0046] Meanwhile, a number of rollers 21 are respectively assembled and connected to the lower ends of the front and rear side walls of the sports car 2. The rollers 21 roll on the track 1. Specifically, to improve the rolling stability, in the same way as the existing method, a track groove adapted to the rollers 21 is provided on the track 1, and the rollers 21 are limited to roll within the track groove.

[0047] In this way, during the process of pushing the sports car 2 to move, the stability of the movement is maintained.

[0048] Embodiment 3

[0049] As Figures 1 - 3 shown, on the basis of the structure of Embodiment 2, the structure of the sports car 2 is disclosed in this embodiment. Specifically, the sports car 2 includes a frame-type vehicle frame 22. Wing beam plates 23 are respectively welded to both sides of the top of the frame-type vehicle frame 22. The long sliding rod 43 is slidably connected to the frame-type vehicle frame 22. In this way, a sports car 2 with a simple structure and high flexibility is assembled and welded with waste steel beams in the workshop, and then it can operate in a narrow working environment to meet the operation requirements.

[0050] Meanwhile, a number of through holes are respectively provided on the front and rear side walls of the frame-type vehicle frame 22. A sliding sleeve 24 is fixedly connected to the through holes. The long sliding rod 43 passes through the through holes and is slidably connected to the sliding sleeve 24. In this way, the stability of the sliding is further improved.

[0051] An internal fixed connection beam 25 is fixedly connected inside the above-mentioned frame-type vehicle frame. The cylinder barrel of the lifting oil cylinder 31 is fixedly installed on the internal fixed connection beam 25.

[0052] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples.
