The present invention arranges a moving plate on the inner wall of the arc-shaped surface of the bucket body so that soil adheres to the moving plate, and uses a pushing component to displace the top surface of the convex block from the surface of the moving plate, so that a number of uneven pits are formed on the surface of the moving plate, so that the adhered soil loses the surface to rely on, and the soil on the arc-shaped surface of the bucket body where the soil blocks are most likely to adhere is easy to detach; by arranging a first airbag and a second airbag on the surface of the moving plate, using the cooperation of a pipeline and a high-speed fan, the soil blocks originally remaining on the moving plate can be lifted up by the lifting plate lifted up by the first airbag and the second airbag after being inflated, so that the soil blocks on the moving plate are more completely detached, and at the same time, the arrangement of the lifting plate is conducive to protecting the airbag and preventing the soil blocks from directly contacting the surface of the airbag and causing damage.

Description

Technical Field

[0001] The present invention relates to the technical field of excavation, and in particular to an excavation device for electric power facilities. Background Art

[0002] Power facility excavation generally refers to ground excavation work for the installation, maintenance, repair or upgrading of power infrastructure (such as cables, pipelines, etc.), therefore, excavators are used.

[0003] For example, the patent with the patent authorization announcement number CN104631528B in the prior art discloses an excavator bucket, the front edge of the inner plate is provided with a main blade plate, the left and right side plates are respectively provided with left and right guard plates extending from the front end of the bottom to the left and right ends of the arc connection part of the bucket bottom, the transverse reinforcing strips are welded at intervals on the outside of the arc connection part, the outside of the front part of the bucket bottom has a longitudinal reinforcing plate welded at intervals, the rear end of the reinforcing plate is welded to the reinforcing strips, the front end of the reinforcing plate is welded to the main blade plate, and there are longitudinal wear-resistant plates between adjacent reinforcing plates and between the reinforcing plate and the left and right guard plates. Compared with the prior art, the beneficial effects of the present invention are strong structural rigidity, more reasonable structural design, reduced excavation resistance, less material, and cost saving.

[0004] Although the above device solves the rigidity problem of the bucket, it still has the following shortcomings:

[0005] When the bucket is in the process of excavation, the inner back of the bucket is set in an arc shape. Under the pressure of weight and the action of soil with a certain viscosity, more mud blocks will adhere to the arc position of the bucket, resulting in a reduction in the volume of the bucket. The actual loading volume is reduced during each excavation, and the accumulated mud will also cause difficulties in later cleaning and maintenance. At this time, one way is to manually use a high-pressure water gun to wash it, which is time-consuming and cannot be cleaned in time. Another way is for the excavator driver to operate the bucket with the opening facing downward, so that the bucket hits and vibrates the ground, so that the mud blocks fall due to the vibration, but this knocking method will cause the bucket to hit the ground, which is easy to cause damage to the bucket teeth. Therefore, the arc position of the existing bucket is inconvenient in removing soil. Summary of the invention

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] See also Figure 1-Figure 12 A power facility excavation equipment includes an excavator body 1 and a bucket body 2 connected to one end of the excavator body 1, the inner wall of the arc-shaped surface of the bucket body 2 is connected to a moving plate 5, a plurality of convex grooves 21 are provided on the moving plate 5, a plurality of convex grooves 21 are slidably connected with convex blocks 4 fixedly connected to the inner part of the arc-shaped surface of the bucket body 2, the top surface of the convex blocks 4 is flush with the outer wall of the moving plate 5, the outer wall of the moving plate 5 is connected to a pushing component, and the inner wall of the moving plate 5 is connected to a lifting component.

[0034] In the electric power facility excavation equipment of the present invention, when the bucket body 2 is excavating, the inner wall of the curved surface of the bucket body 2 will cause mud blocks to adhere due to gravity and sticky soil. At this time, the pushing component is started, driving the movable plate 5 to move within the curved surface of the bucket body 2, so that the movable plate 5 moves a certain distance. When the movable plate 5 moves forward a certain distance, the protrusion 4 in the protrusion groove 21 in the movable plate 5 does not move. At this time, the original plane of the movable plate 5 forms uneven pits under the setting of the protrusion 4, which can make the whole piece of mud attached lose the surface on which it relies on for adhesion, so that the mud can fall off the movable plate 5.

[0035] Here, when the movable plate 5 is started to remove soil, the opening of the bucket body 2 is ensured to be in the lower position as much as possible, so that the soil blocks can fall out as much as possible.

[0036] By arranging a movable plate 5 on the inner wall of the curved surface of the bucket body 2, the soil can be attached to the movable plate 5. By utilizing the pushing assembly, the top surface of the protrusion 4 and the surface of the movable plate 5 are misaligned, thereby forming uneven pits on the surface of the movable plate 5, causing the adhered soil to lose the surface to adhere to, thereby ensuring that the soil blocks are separated from the surface of the movable plate 5, making it easy for the soil on the curved surface of the bucket body 2 where the soil blocks are most likely to adhere to to be separated.

[0037] As a preferred technical solution of the present invention, the pushing assembly includes an outer plate 16 and a plurality of moving rods 31. The outer plate 16 is installed on the outer wall of the bucket body 2. The moving rods 31 are symmetrically arranged in pairs on the inner wall of the outer plate 16. One end of the moving rod 31 passes through the arc surface of the bucket body 2 and is fixedly connected to the moving plate 5. An electric push rod 24 is fixedly installed on the outer wall of the arc surface of the bucket body 2. The output end of the electric push rod 24 is fixedly connected to the outer plate 16. A moving groove 35 corresponding to the position of the moving rod 31 is opened on the arc surface of the bucket body 2, and a protective member is connected to the outer side of the outer plate 16.

[0038] Specifically, when the movable plate 5 needs to be moved, the electric push rod 24 is started, and the output end of the electric push rod 24 will drive the outer plate 16 to extend and retract, thereby realizing the movement of the movable plate 5 within the curved surface of the bucket body 2. When the outer plate 16 moves, it will drive multiple movable rods 31 to move in the movable groove 35, and the movable rods 31 will drive the movable plate 5 to move, thereby realizing the movement of the movable plate 5.

[0039] As a preferred technical solution of the present invention, the lifting component includes a first airbag 19 and a second airbag 20. The inner wall of the movable plate 5 is provided with a plurality of transversely arranged embedding grooves 18, and the first airbag 19 and the second airbag 20 are fixedly embedded in the plurality of embedding grooves 18, respectively. The outer walls of the first airbag 19 and the second airbag 20 are fixedly connected with a lifting plate 17, and the lifting plate 17 is located in the embedding groove 18. An airbag tube 22 embedded in the movable plate 5 is connected between the first airbag 19 and the second airbag 20. One end of the airbag tube 22 at the top of the first airbag 19 that passes through the movable plate 5 is fixedly connected to a bucket tube 15 that passes through the bucket body 2. A high-speed fan 12 is fixedly installed on the top of the bucket body 2, and a fan pipe 13 is fixedly connected to the outer side of the air outlet of the high-speed fan 12. A connecting pipe 14 is arranged between the fan pipe 13 and the bucket pipe 15, and a filter is connected to the outer side of the high-speed fan 12.

[0040] Specifically, in order to make the mud blocks on the surface of the movable plate 5 detach more thoroughly, at this time, the high-speed fan 12 can be started, and the high-speed fan 12 inputs the wind flow into the fan pipe 13 of the air outlet through the air inlet, and the wind flow is input into the first air bag 19 and the second air bag 20 through the fan pipe 13, the connecting pipe 14, the bucket pipe 15 and the air bag pipe 22, so that the first air bag 19 and the second air bag 20 are inflated, and the mud blocks remaining on the movable plate 5 are lifted up by the lifting plate 17 at the same time, so that the remaining mud blocks are again detached more thoroughly;

[0041] The volumes of the first airbag 19 and the second airbag 20 are not equal, and the second airbag 20 can be higher than the first airbag 19. In this way, a height difference can be formed between the lifting plate 17 of the first airbag 19 and the lifting plate 17 of the second airbag 20 after they are lifted up, which is more conducive to the separation of soil blocks. The first airbag 19 and the second airbag 20 can be composed of multiple components and should be cross-arranged.

[0042] Here, the fan pipe 13, the connecting pipe 14, and the bucket pipe 15 can be covered with a protective cover with corrosion resistance, waterproof performance, etc. to extend the service life when used outdoors.

[0043] By arranging the first airbag 19 and the second airbag 20 on the surface of the movable plate 5 and utilizing the coordinated arrangement of the pipeline and the high-speed fan 12, the mud blocks originally remaining on the movable plate 5 can be lifted up by the lifting plate 17 which is lifted up after the first airbag 19 and the second airbag 20 are inflated, thereby achieving a more thorough detachment of the mud blocks on the movable plate 5. The arrangement of the lifting plate 17 is also beneficial to the protection of the airbag, preventing the mud blocks from directly contacting the surface of the airbag and causing damage.

[0044] As a preferred technical solution of the present invention, the protective part includes a protective cover 3, the cross-section of the protective cover 3 is arc-shaped, and the protective cover 3 is located on the outer wall of the outer plate 16. The outer wall of the bucket body 2 is fixedly connected with two U-shaped clamps 9, and the upper and lower ends of the protective cover 3 are plugged into the U-shaped clamps 9. The outer walls of the protective cover 3 are fixedly connected with symmetrically arranged L-shaped straps 10. The outer walls of the L-shaped straps 10 are threadedly connected with a first threaded rod 11, and one end of the first threaded rod 11 is passed through the L-shaped strap 10 and is threadedly connected to the outer wall of the bucket body 2.

[0045] Specifically, in order to prevent the bucket body 2 from contaminating the outer plate 16 and the electric push rod 24 during the excavation process, the protective cover 3 can be set to protect them. During installation, it is only necessary to connect the upper and lower ends of the protective cover 3 with the two U-shaped clamps 9, and then thread the first threaded rod 11 on the outside of the L-shaped strap 10 with the outer wall of the bucket body 2 to fix it. The protective cover 3 can protect the outer plate 16 and the electric push rod 24, and the cross-section of the protective cover 3 is set to be arc-shaped, which can ensure the smoothness of the bucket body 2 during excavation.

[0046] As a preferred technical solution of the present invention, a plurality of wear-resistant plates 8 are fixedly connected to the outer wall of the protective cover 3 .

[0047] Specifically, the provision of the wear-resistant plate 8 can increase the service life of the protective cover 3 during the excavation process of the bucket body 2.

[0048] As a preferred technical solution of the present invention, the filter element includes an installation box 6, which is fixedly arranged on the top side of the bucket body 2. The installation box 6 is arranged with a top opening, and the top of the installation box 6 is detachably connected to a box cover 7. The high-speed fan 12 is located in the installation box 6. A pipe groove 30 is opened on one side of the outer wall of the installation box 6. The air outlet of the high-speed fan 12 is connected to the fan pipe 13 through the pipe groove 30. An annular groove 25 is opened on the outer wall of the installation box 6 on the side close to the air inlet of the high-speed fan 12. A filter ring plate 26 is detachably connected in the annular groove 25, and a filter combination plate 27 is fixedly connected in the filter ring plate 26.

[0049] Specifically, in order to prevent the high-speed fan 12 from having its air inlet blocked and its service life reduced in the harsh environment of the construction site, the high-speed fan 12 can be installed in the installation box 6. At the same time, the outer wall of the installation box 6 is provided with a filter ring plate 26 corresponding to the air inlet position of the high-speed fan 12. The filter ring plate 26 is provided with a filter combination plate 27. The filter combination plate 27 can be composed of a non-woven filter mesh, a nylon filter mesh, etc., which can not only ensure the blocking of dust, but also reduce wind resistance and ensure wind speed.

[0050] The filter ring plate 26 here can be detachably connected to the annular groove 25, so that the filter ring plate 26 and the filter combination plate 27 can be easily disassembled.

[0051] As a preferred technical solution of the present invention, vertical plates 28 are fixedly connected to both sides of the bottom of the box cover 7, and a third threaded rod 29 is threadedly connected to the vertical plate 28. One end of the third threaded rod 29 passes through the vertical plate 28 and is threadedly connected to the outer wall of the installation box 6.

[0052] Specifically, in order to facilitate the installation and disassembly of the high-speed fan 12, the third threaded rod 29 can be separated or installed from the vertical plate 28 to ensure that the box cover 7 is installed and fixed and easy to disassemble.

[0053] As a preferred technical solution of the present invention, the outer wall of the outer plate 16 is provided with a second threaded rod 23 corresponding to the position of a plurality of moving rods 31, a thread groove 34 is opened at the end of the moving rod 31, one end of the second threaded rod 23 passes through the outer plate 16 and is threadedly connected to the thread groove 34, and the second threaded rod 23 is fixedly connected with a hexagonal boss 32 at one end away from the moving rod 31, and an elastic pad 33 is sleeved on the outer side of the second threaded rod 23, and the elastic pad 33 is against the arc-shaped outer wall of the outer plate 16.

[0054] Specifically, in order to facilitate the removal of the movable plate 5, the second threaded rod 23 can be disassembled to separate the second threaded rod 23 from the outer wall of the outer plate 16, and then the outer plate 16 is separated from the plurality of movable rods 31, and the movable plate 5 can be removed.

[0055] Since the outer plate 16 is arranged in an arc shape, when the second threaded rod 23 is connected to the moving rod 31 , the elastic pad 33 will be pressed against the outer wall of the outer plate 16 . This arrangement can improve the stability between the second threaded rod 23 and the outer plate 16 and the moving rod 31 .

[0056] In the above structure, the high-speed fan 12 and the electric push rod 24 are existing mature technologies, so they will not be described in detail here. The power-on drive of the high-speed fan 12 and the electric push rod 24 can be driven to open and close by switches such as solenoid valves, and they should be able to be driven in the cab of the excavator body 1.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
