Description

Technical Field

[0001] This invention relates to the field of electric shovels, and in particular to a cleaning device for use on the shovel's rotary platform. Background Technology

[0002] Electric shovels are one of the main mining equipment in open-pit mines with a capacity of tens of millions of tons. They are highly productive, have a high operating rate, and low operating costs, making them a recognized model in the mining industry. An electric shovel consists of a traveling mechanism, a slewing mechanism, a working mechanism, a lubrication system, and an air supply system. The bucket is the main component of the electric shovel, directly bearing the force of the ore being excavated, and therefore experiences significant wear. The boom is also a key component in the excavation process; its function is to connect and support the bucket, and to transmit the pushing force to the bucket. Under the combined action of pushing and lifting forces, the bucket completes the excavation of the soil.

[0003] Electric shovels are the primary mining equipment in modern open-pit mines. The bucket of an electric shovel is typically rigidly fixed to the boom and pulled into the material to be excavated by a steel cable. It can only move in a forced circular motion in one direction, rather than working according to the composition of the excavated material, thus preventing the bucket from following the ore layer. Since an electric shovel can only exert its digging force in one direction, its working device must be very heavy to resist the digging force. To balance this, the weight of the machine body also increases accordingly. Therefore, the overall weight of a mechanical electric shovel is very large, and counterweights may also be required. The digging force on the bucket comes from the vertical component of the cable tension. Generally, only 28%-60% of the static cable tension is used for digging. Because electric shovels operate outdoors, the slewing mechanism can be affected by the accumulation of silt or impurities, thus affecting its rotation efficiency. Therefore, a device for cleaning the slewing mechanism is needed. Summary of the Invention

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1

[0034] Reference Figures 1-3This is the first embodiment of the present invention. This embodiment provides a cleaning device applied to the rotating platform of an electric shovel. The device is characterized by including an electric shovel 100, on which a rotating platform 101 is provided. The electric shovel 100 is one of the main mining equipment in open-pit mines with a capacity of tens of millions of tons. It has high productivity, high operating rate, and low operating cost. It is a recognized model in the mining industry. The electric shovel 100 consists of a walking device, a rotating device, a working device, a lubrication system, and an air supply system. The bucket is the main component of the electric shovel 100. It directly bears the force of the ore being excavated, and therefore experiences greater wear. The boom is also one of the main components in the excavation process of the electric shovel 100. Its function is to connect and support the bucket and transmit the pushing force to the bucket. Under the combined action of pushing and lifting forces, the bucket completes the action of excavating the soil. The rotating platform 101 is located between the cab and the tracks, allowing the cab to be steered.

[0035] The water spraying unit 200 includes a spring cover 201, a placement plate 202 coaxially disposed at the bottom end of the spring cover 201, a bundle tube 203 coaxially disposed at the bottom end of the placement plate 202, a limiting platform 204 coaxially sleeved on the bundle tube 203, and a water pipe 205 disposed in the placement plate 202. The spring cover 201 and the placement plate 202 cooperate to limit and fix the water pipe 205. The bundle tube 203 is used to further constrain the water pipe 205 to prevent the water pipe from tangling and affecting the water output efficiency. The limiting platform 204 cooperates with the spring cover 201 to fix the spring cover 201 on the placement plate 202.

[0036] The cleaning unit 300 includes a rotating disk 301 coaxially disposed at the bottom of the limiting platform 204, a cleaning component 302 rotatably connected to the outer wall of the rotating disk 301, and a reversing disk 303 coaxially disposed in the inner cavity of the rotating disk 301. The rotation of the rotating disk 301 will drive the rotation of the entire water spraying unit 200. The reversing disk 303 is fixed. When the reversing disk 303 rotates, it will drive the cleaning component 302 to rotate. Under the action of the reversing disk 303, the cleaning component 302 will have rotational force in both the horizontal and vertical directions.

[0037] Example 2

[0038] Reference Figures 2-7This is the second embodiment of the present invention, which is based on the previous embodiment. The rotating platform 101 includes a top plate 101a, a support column 101b disposed at the bottom end of the top plate 101a, and a chassis 101c disposed at the bottom end face of the support column 101b. The bottom end of the top plate 101a is recessed to form a first annular groove 101a-1, and the chassis 101c is provided with a second annular groove 101c-1. The second annular groove 101c-1 is provided with teeth 101c-2 and drainage holes 101c-3. The rotating platform is connected to the cab and tracks of the electric shovel 100 to ensure the steering of the cab and the bucket. By setting the first annular groove 101a-1 and the second annular groove 101c-1, the cleaning unit 300 can make circular motion on the rotating platform 101 along the direction of the first annular groove 101a-1 and the second annular groove 101c-1.

[0039] In detail, the top of the spring cover 201 has a protruding post 201a, which slides on the inner wall of the first annular groove 101a-1. The spring cover 201 also includes an elastic limiting member 201b and a first water pipe groove 201c disposed on the bottom end face of the spring cover 201. An arc-shaped block 201b-1 is provided at one end of the elastic limiting member 201b extending from the top of the spring cover 201 into the first water pipe groove 201c. The bottom end of the spring cover 201 also has a protruding limiting post 201. d and the fitting post 201e, the fitting post 201e is provided with a locking block 201e-1, and the spring cover 201 is limited to slide in the first annular groove 101a-1 by setting the protruding post 201a. Here, the protruding post 201a can be set as a telescopic rod, which makes it easy to disengage the spring cover 201 from the first annular groove 101a-1. During installation, the arc-shaped block 201b-1 set in the elastic limiting member 201b will fix the water pipe 205 to prevent it from shaking.

[0040] Furthermore, a second water pipe groove 202a and a limiting groove 202b are formed in the recessed top of the placement tray 202. One end of the water pipe 205 is set in the second water pipe groove 202a, and the limiting post 201d penetrates the limiting groove 202b. A through hole 202c is formed in the recessed top of the placement tray 202. The first water pipe groove 201c and the second water pipe groove 202a cooperate to form a complete circular space. When the spring cover 201 is installed on the placement tray 202, the first... There will be a misalignment between the first water pipe groove 201c and the second water pipe groove 202a. At this time, the spring cover 201 can be rotated to align the first water pipe groove 201c with the second water pipe groove 202a. During the rotation, the limiting post 201d slides in the limiting groove 202b. After the first water pipe groove 201c and the second water pipe groove 202a are aligned, the arc block 201b-1 will pop out and lock onto the water pipe 205, thus achieving the initial fixation of the water pipe 205.

[0041] Furthermore, a first limiting plate 203a and a second limiting plate 203b are provided inside the bundle tube 203. The first limiting plate 203a is fixedly connected to the inner wall of the bundle tube 203, and a sleeve 203a-1 is fixedly connected to the first limiting plate 203a. The inner wall of the sleeve 203a-1 is provided with an arc-shaped piece 203a-2 and a round hole 203a-3. The arc-shaped piece 203a-2 is slidably connected to the inner wall of the round hole 203a-3, and the second limiting plate 203b is slidably connected to the outer wall of the sleeve 203a-1. The first limiting plate 203a simultaneously limits multiple water pipes 205 to prevent them from getting tangled together during use and affecting the water output. The second limiting plate 203b provides secondary limiting for the water pipes 205 to improve their stability.

[0042] Furthermore, a spring compression assembly 204a is provided at the top of the limiting platform 204. The spring compression assembly 204a includes a support rod 204b, a pressing piece 204c disposed on the top end face of the support rod 204b, a pressing hole 204d formed by the recess at the top of the pressing piece 204c, and a spring 204e disposed at the end of the pressing piece 204c away from the support rod 204b. A tube hole 204f is also formed by the recess at the top of the limiting platform 204.

[0043] The working principle of this embodiment:

[0044] When assembling this device, first, multiple water pipes 205 are passed through the bundle tube 203. The water pipes 205 are initially limited by the first limiting plate 203a. Then, the second limiting plate 203b is installed inside the bundle tube 203. The second limiting plate 203b can move freely up and down within the bundle tube 203. Adjust the position of the spring cover 201 and install it onto the placement plate 202 so that the limiting post 201d can be embedded in the limiting groove 202b. At the same time, the fitting post 201e extends into the bundle tube 203, and the locking block 201e-1 on the fitting post 201e abuts against the concave point of the arc-shaped piece 203a-2. At this time, rotate the spring cover 201 so that the first water pipe groove 201c and the second water pipe groove 202a are aligned with each other. Simultaneously, the limiting post 201d slides in the limiting groove 202b, with one end of the limiting post 201d abutting against one end of the pressing piece 204c. When the first water pipe groove 201c and the second water pipe groove 202a are aligned, fixation in three directions is achieved. First, the elastic limiting member 201b will engage with the water pipe 205 under the action of elastic force. Second, when the limiting post 201d moves to the other end of the pressing piece 204c, the spring 204e is compressed. After the limiting post 201d is inserted into the pressing hole 204d, the spring 204e rebounds, and the spring cover 201 is limited and cannot rotate. Third, the locking block 201e-1 abuts against the concave point of the arc-shaped piece 203a-2 under the rotation of the spring cover 201.

[0045] The device moves to abut against the protrusion of the arc-shaped piece 203a-2, causing the arc-shaped piece 203a-2 to expand to both sides. One end of the arc-shaped piece 203a-2 extending out of the bundle tube 203 is located below the second limiting plate 203b, thus fixing the second limiting plate 203b and preventing it from falling off during device operation.

[0046] Example 3

[0047] Reference Figures 8-9 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment. The top of the rotating disk 301 is provided with a water pipe hole 301a, and the water pipe 205 passes through the water pipe hole 301a. The end of the cleaning member 302 extending out of the rotating disk 301 is provided with a brush column 302a. The end of the cleaning member 302 located inside the rotating disk 301 is provided with an arc-shaped rotating plate 302b. A steering column 302c is provided on the arc-shaped rotating plate 302b. The rotation of the rotating disk 301 drives the rotation of the cleaning member 302.

[0048] Furthermore, a rotating water tank 303a is formed by a recess at the top of the commutator 303. A fixing post 303b and a water supply pipe 303a-1 are provided at the bottom of the rotating water tank 303a. A fixing block 303c is provided on the fixing post 303b. A third annular groove 101c-4 is provided on the inner wall of the second annular groove 101c-1. The fixing block 303c is embedded in the third annular groove 101c-4. A convex groove 303d is also provided on the side of the commutator 303.

[0049] Furthermore, a support plate 303b-1 is provided on the fixed column 303b, a triangular block 303b-2 is provided on the support plate 303b-1, a hanging plate 303b-3 is connected to the top of the inner wall of the steering wheel 303, and a shaft hole 303b-4 is formed through the fixed column 303b from the top.

[0050] Furthermore, a rotating shaft 301d is provided on the rotating disk 301, a gear 301d-1 is provided on the rotating shaft 301d, a motor 301d-2 is provided at the bottom end of the gear 301d-1, the gear 301d-1 meshes with the teeth 101c-2, a water storage tank 101c-5 is provided inside the chassis 101c, and a water supply pipe 303a-1 extends into the water storage tank 101c-5.

[0051] The working principle of this embodiment:

[0052] The drive motor 301d-2 rotates, which in turn drives the gear 301d-1 to rotate. The rotation of the gear 301d-1 causes the rotating disk 301 to move in a circular motion along the direction of the first annular groove 101a-1. Simultaneously, the rotating disk 301 also rotates on its own axis, causing the cleaning component 302 to move in a circular motion. The steering wheel 303 remains stationary relative to the rotating disk 301. Therefore, the steering column 302 slides along the bottom end of the steering wheel 303. When the steering column 302 moves to the convex groove 303d, it will move in conjunction with the triangular block 303b-2. The cleaning component 302 is flipped over. A water pump is installed in the water supply pipe 303a-1 to pump water from the water storage tank 101c-5 into the rotating water tank 303a. Since the rotating water tank 303a is located on the reversing disk 303, it remains stationary relative to the rotating disk 301. Therefore, the water pipe 205 rotates in the rotating water tank 303a. Each water pipe 205 is equipped with a water pump and a nozzle to draw water from the rotating water tank 303a into the water pipe 205, which then sprays water onto the cleaning component 302. This not only suppresses dust but also continuously washes the cleaning component 302, improving the cleaning effect.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
