Description

Technical Field

[0001] The invention belongs to the technical field of drainage ditch cleaning, and in particular relates to a track-type underground mine drainage ditch sludge cleaning device. Background Art

[0002] Track-type mines are a type of mine transportation method that uses a track system to transport minerals and equipment. Track-type mine transportation systems play an important role in mine production and operations; they can not only efficiently transport ore, coal and other minerals to ensure the continuity of production, but also transport personnel and equipment to improve work efficiency and safety. Especially in underground mines, track-type transportation systems can reduce personnel's walking distance and labor intensity, and improve overall work efficiency. In addition, when an accident occurs in a mine, the track-type transportation system can also be used as a means of transporting emergency rescue equipment to quickly deliver rescue equipment and personnel to the accident site.

[0003] To remove water from the mine, Figure 1 As shown, a sewer ditch parallel to the rail transport system is often set up in a rail mine. After a period of drainage, silt will accumulate in the sewer ditch, affecting the smooth drainage. Therefore, the sewer ditch needs to be cleaned of silt regularly.

[0004] However, mine tunnels are often designed to be very narrow for support safety considerations, which brings great inconvenience to the cleaning of sludge in sewer ditches. If manual cleaning is used, it is not only time-consuming and labor-intensive, but also poses a safety hazard of mine tunnel collapse; and conventional sewer sludge cleaning devices are difficult to operate in narrow mine tunnels; in order to solve the above problems, the present invention proposes a track-type mine underground ditch sludge cleaning device. Summary of the invention

[0005] The present invention aims at solving the problems in the prior art and proposes the following technical solutions:

[0007] Under the connection of the connecting components and the drive of the rail vehicle, the silt clearing mechanism clears the sludge along the sewer ditch, and at the same time collects the cleared sludge through the sludge collecting mechanism, thereby realizing the automatic cleaning of the sludge in the underground ditch of the track-type mine.

[0008] As a preferred embodiment of the above technical solution, the sludge collection mechanism includes a collection box installed on a rail car, a pump body is installed on the collection box, an input end of the pump body is interconnected with a delivery pipe, and an output end of the pump body extends to the interior of the collection box.

[0009] As a preferred embodiment of the above technical solution, the connecting assembly includes a connecting plate fixedly connected to the side wall of the rail vehicle and a sleeve rod fixedly connected to the dredging mechanism, the other end of the connecting plate is fixedly connected to a ring, the ring is movably sleeved on the periphery of the sleeve rod and the inner diameter is larger than the diameter of the sleeve rod, and one end of the sleeve rod away from the dredging mechanism is fixedly connected to a limiting disk, and the diameter of the limiting disk is larger than the outer diameter of the ring.

[0010] As a preferred embodiment of the above technical solution, the dredging mechanism includes a sludge transfer vehicle, and the width of the sludge transfer vehicle is smaller than the width of the sewer ditch, a shovel head is fixedly connected to the front of the sludge transfer vehicle, and side shovel bars are arranged on both sides of the sludge transfer vehicle.

[0011] As a preferred embodiment of the above technical solution, two elastic support components are provided on both sides of the sludge transfer vehicle, and the elastic support components are used to adjust the position of the sludge transfer vehicle in the sewer ditch.

[0012] As a preferred embodiment of the above technical solution, the elastic support assembly includes a fixed cylinder fixedly connected to the side of the sludge transfer vehicle, a sliding rod is slidably inserted into the inner wall of the fixed cylinder, a roller is installed at the end of the sliding rod away from the fixed cylinder, and a spring is fixedly installed at the other end of the sliding rod, and the other end of the spring is fixed to the outer wall of the sludge transfer vehicle.

[0013] As a preferred embodiment of the above technical solution, the inner wall of the shovel head is slidably connected with two symmetrically arranged extended shovels, and the extended shovels and the side shovel bars are fixed by a second connecting bar;

[0014] The side wall of the sludge transfer vehicle is fixedly connected with a fixed plate, and one end of the side shovel bar close to the sludge transfer vehicle is slidably sleeved on the periphery of the fixed plate;

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0028] Example

[0029] like Figure 2 As shown, a track-type underground mine ditch sludge cleaning device includes a track vehicle 10 adapted to the track and a silt removal mechanism 30 adapted to the ditch. The track vehicle 10 and the silt removal mechanism 30 are connected via a connecting assembly 40. The track vehicle 10 is provided with a silt collection mechanism 20 for collecting silt removed by the silt removal mechanism 30.

[0030] The present invention utilizes the track in the mine and sets a rail vehicle 10 that can travel on the track. Under the connection of the connecting component 40 and the drive of the rail vehicle 10, the silt clearing mechanism 30 is pushed along the sewer ditch to clean the silt. At the same time, the cleaned silt is collected by the silt collecting mechanism 20, thereby realizing the automatic cleaning of the silt in the underground ditch of the track-type mine. It is suitable for narrow mine space and the silt cleaning is more convenient.

[0031] The sludge collection mechanism 20 includes a collection box 21 installed on the rail car 10, and a pump body 22 is installed on the collection box 21. The input end of the pump body 22 is interconnected with a delivery pipe 23. The other end of the delivery pipe 23 is placed on the bottom inner wall of the sludge transfer vehicle 31 to absorb the sludge temporarily stored in the sludge transfer vehicle 31. The output end of the pump body 22 extends to the interior of the collection box 21.

[0032] The connecting assembly 40 includes a connecting plate 44 fixedly connected to the side wall of the rail vehicle 10 and a sleeve rod 41 fixedly connected to the dredging mechanism 30. The other end of the connecting plate 44 is fixedly connected to a collar 42. The collar 42 is movably sleeved on the periphery of the sleeve rod 41 and has an inner diameter greater than the diameter of the sleeve rod 41. One end of the sleeve rod 41 away from the dredging mechanism 30 is fixedly connected to a limit plate 43, and the diameter of the limit plate 43 is greater than the outer diameter of the collar 42.

[0033] Due to the construction process, the track and the bottom of the sewer ditch are not completely parallel. Therefore, setting the inner diameter of the ring 42 larger than the diameter of the sleeve rod 41 can ensure that the height of the dredging mechanism 30 will not be affected when the rail vehicle 10 pushes the dredging mechanism 30 forward, so that the dredging mechanism 30 always remains in a forward state close to the bottom of the sewer ditch.

[0034] The silt removal mechanism 30 includes a silt transfer vehicle 31, and the width of the silt transfer vehicle 31 is smaller than the width of the lower ditch. A shovel head 32 is fixedly connected to the front of the silt transfer vehicle 31, and side shovel bars 33 are arranged on both sides of the silt transfer vehicle 31. The side shovel bars 33 can be used to push the silt at the bottom of the lower ditch and the side wall silt at a lower position through the mud inlet 311 to the silt transfer vehicle 31 for temporary storage, and the side wall silt at a higher position can be pushed to the bottom of the lower ditch first by the side shovel bars 33, and then pushed by the shovel head 32 through the mud inlet 311 to the silt transfer vehicle 31 for temporary storage.

[0035] A counterweight 37 is provided on the back of the sludge transfer vehicle 31 to prevent the vehicle from tilting forward when shoveling sludge.

[0036] Two elastic support components 34 are provided on both sides of the sludge transfer vehicle 31, and the elastic support components 34 are used to adjust the position of the sludge transfer vehicle 31 in the sewer ditch; thereby, the overall forward trajectory of the dredging mechanism 30 is aligned with the sewer ditch, avoiding collision between the side shovel bars 33, the shovel head 32 and other components and the side walls of the sewer ditch.

[0037] The elastic support assembly 34 includes a fixed cylinder 341 fixedly connected to the side of the sludge transfer vehicle 31, a sliding rod 342 is slidably inserted into the inner wall of the fixed cylinder 341, a roller 344 is installed at one end of the sliding rod 342 away from the fixed cylinder 341, and a spring 343 is fixedly installed at the other end of the sliding rod 342, and the other end of the spring 343 is fixed to the outer wall of the sludge transfer vehicle 31.

[0038] The inner wall of the shovel head 32 is slidably connected with two symmetrically arranged extended shovels 321, and the extended shovels 321 and the side shovel strips 33 are fixed by a second connecting strip 38;

[0039] The side wall of the sludge transfer vehicle 31 is fixedly connected with a fixing plate 35, and one end of the side shovel bar 33 close to the sludge transfer vehicle 31 is slidably sleeved on the outer periphery of the fixing plate 35;

[0040] A first connecting bar 36 is fixedly connected between the sliding rod 342 in the front elastic support assembly 34 and the side shovel bar 33 .

[0041] By providing the extended shovel 321, the width of both sides of the shovel head 32 can be increased to adapt to the width of the sewer ditch, thereby making the silt at the bottom of the sewer ditch and the lower side wall cleaning more thorough.

[0042] When the dredging mechanism 30 moves forward at the bend position of the sewer ditch, under the elastic adjustment of the spring 343, the roller 344 always fits the side wall of the sewer ditch, and the sliding rod 342 is correspondingly extended and retracted; under the connection between the first connecting bar 36 and the second connecting bar 38, the extension and retraction of the sliding rod 342 in the front elastic support assembly 34 drives the side shovel bar 33 and the extension shovel 321 to make corresponding extension and retraction on both sides, so that the side shovel bar 33 and the extension shovel 321 can follow the extension and retraction adjustment position and be close to the side wall of the sewer ditch even when the dredging mechanism 30 moves forward in the bend area of ​​the sewer ditch, thereby further improving the cleaning effect of the dredging mechanism 30 when it moves forward in the bend area of ​​the sewer ditch.

[0043] The side shovel bar 33 is located above the shovel head 32, and a bending portion 331 is provided on the side shovel bar 33. By providing the bending portion 331, it is convenient to guide the silt accumulated by the extended shovel 321 along the bending portion 331 through the mud inlet 311 into the silt transfer vehicle 31 for temporary storage.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
