Description

Technical Field

[0001] This utility model relates to a chain cleaning auxiliary device and a chain transmission device. Background Technology

[0002] Chain drive equipment, as a core transmission device, is widely used in the following fields due to its high load-bearing capacity, stability, and flexibility: In industrial manufacturing, it is used for the automated transfer of raw materials, semi-finished products, and finished products; in automated warehousing and logistics, it works with stacker cranes in automated warehouses to achieve efficient storage and retrieval of goods; in the mining and metallurgical industry, it carries heavy materials such as ore and coal for continuous transport, meeting the needs of high-intensity operations, and high-temperature resistant chains are suitable for conveying molten metal or high-temperature materials in the metallurgical industry; it also has extremely wide applications in the food and pharmaceutical industries, agriculture and fisheries, construction and building materials transportation, and intelligent interconnected systems. It enables continuous, high-efficiency, and large-angle transport. It has high adaptability, durability, and significantly improved efficiency. Chain drive equipment is characterized by its ease of use, easy maintenance, and low transportation costs.

[0003] When a chain runs continuously within a track, especially with the track grooves facing upwards, friction between the chain bearings and the track is inevitable. This friction generates metal shavings, which mix with oil to form sludge that accumulates inside the track and inevitably adheres to the bearings. This accelerates the friction between the chain and the track and damages the chain bearings. Therefore, it is necessary to clean the chain.

[0004] The common practice for cleaning existing chain drive equipment is to disassemble a section of chain, about 10 meters long, clean that section, reassemble it, and then disassemble another section, repeating this process until the entire chain is cleaned. However, while this method is time-saving and labor-saving, it results in long maintenance times for the chain drive equipment and low cleaning efficiency.

[0005] In view of this, it is necessary to improve the existing chain cleaning methods to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a chain cleaning auxiliary device to solve the problems of time-consuming, labor-intensive, and inefficient cleaning methods in existing methods.

[0007] To achieve the above objectives, this utility model provides a chain cleaning auxiliary device for placing in a track to support the chain for cleaning. The chain cleaning auxiliary device includes an upper arch plate for placing in the track and multiple support plates arranged below the upper arch plate to support the upper arch plate. The multiple support plates are spaced apart along the extension direction of the upper arch plate. The upper arch plate has an arc-shaped cross-section, and the support plate in the middle is higher than the support plates at both ends.

[0008] As a further improvement of this utility model, the chain cleaning auxiliary device also includes a base plate, which extends horizontally and connects the two ends of the upper arch plate, and the lower ends of the plurality of support plates are fixedly connected to the base plate.

[0009] As a further improvement of this utility model, the chain cleaning auxiliary device further includes at least two limiting frames, which are used to support the track along the track width direction and are fixed to the upper arch plate.

[0010] As a further improvement of this utility model, the limiting frame includes a connecting member fixedly connected to the bottom of the upper arch plate and extending downward, a support plate fixedly connected to the bottom of the connecting member and extending along the width direction of the upper arch plate, and limiting plates disposed at both ends of the extension direction of the support plate. The limiting plates are used to hold the two sides of the track.

[0011] As a further improvement of this utility model, the height difference between the lower side of the support plate and the base plate is equal to the height of the track.

[0012] As a further improvement of this utility model, the number of support plates is three, including a first support plate disposed in the middle and two second support plates disposed on both sides of the first support plate, with the two second support plates being symmetrically arranged.

[0013] As a further improvement of this utility model, the number of the limiting frames is two, and the two limiting frames are symmetrically arranged on both sides of the first support plate, with each limiting frame located between the first support plate and the second support plate.

[0014] As a further improvement of this utility model, the height difference between the highest point of the upper arch plate and the lowest points at both ends is greater than the height of the track.

[0015] This utility model also provides a chain drive device, which includes a track, a chain for transmission within the track, and a chain cleaning auxiliary device as described above. The chain drive device has a working state and a cleaning state. When the chain drive device is in the working state, the chain runs within the track, and the chain cleaning auxiliary device is disengaged from the track. When the chain drive device is in the cleaning state, the chain cleaning auxiliary device is within the track, and the chain protrudes from the track when passing the chain cleaning auxiliary device.

[0016] The beneficial effects of this utility model are: the chain cleaning auxiliary device and chain transmission equipment of this utility model eliminate the tedious disassembly, heavy handling and reassembly process of the chain in the past, which greatly reduces the chain cleaning time, saves time and effort and improves economic efficiency; and the chain operation is continuous, which provides conditions for the subsequent development of automated cleaning.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] like Figures 1 to 4 As shown, the chain drive device 100 of this utility model includes a track 2, a chain 3 for transmission within the track 2, a tensioning device for tensioning the chain 3, and a chain cleaning auxiliary device 1.

[0026] The chain drive device 100 has a working state and a cleaning state. When the chain drive device 100 is in the working state, the chain 3 runs within the track 2, and the chain cleaning auxiliary device 1 is disengaged from the track 2. When the chain drive device 100 is in the cleaning state, the chain cleaning auxiliary device 1 is within the track 2, and the chain 3 protrudes from the track 2 when passing the chain cleaning auxiliary device 1, thereby facilitating the worker to clean the chain 3 outside the track 2.

[0027] In this embodiment, the track 2 has a U-shaped cross-section and an upward opening. When the chain drive device 100 is in operation, the chain 3 is housed within the track 2.

[0028] The chain 3 is equipped with rollers, bearings and other structures.

[0029] The chain cleaning auxiliary device 1 is used to place in the track 2 to support the chain 3 for cleaning. The chain cleaning auxiliary device 1 includes an upper arch plate 11 for placement in the track 2, a plurality of support plates 12 arranged below the upper arch plate 11 to support the upper arch plate 11, at least two limiting frames 13, and a base plate 14.

[0030] The upper arch plate 11 has an arc-shaped cross section. More specifically, the upper arch plate 11 has a circular arc-shaped cross section along the width direction of the track 2. The support plate 12 and the bottom plate 14 are used to support the upper arch plate 11 to maintain its circular arc shape in order to ensure load-bearing capacity.

[0031] The height difference between the highest point of the upper arch plate 11 and the lowest points at both ends is greater than the height of the track 2, so that even if the two ends of the upper arch plate 11 are in contact with the bottom of the track 2, the chain 3 passing through the highest point of the upper arch plate 11 can still protrude outside the track 2.

[0032] In this embodiment, the base plate 14 extends horizontally and connects the two ends of the upper arch plate 11. The bottom of the base plate 14 is supported in the track 2 to support the upper arch plate 11.

[0033] In other embodiments, the base plate 14 may not be directly connected to the upper arch plate 11, but only to the support plate 12.

[0034] The plurality of support plates 12 are spaced apart along the extending direction of the upper arch plate 11, and the support plate 12 located in the middle is higher than the support plates 12 located at both ends.

[0035] The lower ends of the plurality of support plates 12 are fixedly connected to the base plate 14.

[0036] The number of support plates 12 is three, including a first support plate 121 disposed in the middle and two second support plates 122 disposed on both sides of the first support plate 121, with the two second support plates 122 being symmetrically arranged.

[0037] In this embodiment, the support frame is spaced apart along the extending direction of the upper arch plate 11 to support the upper arch plate 11 at multiple locations. Preferably, there is an odd number of support plates 12, with the middle one being the highest, and the support plates 12 on both sides being symmetrically arranged.

[0038] The limiting frame 13 is used to support the track 2 along its width direction, and is fixed to the upper arch plate 11. In this embodiment, the limiting frame 13 serves as an auxiliary support, preventing damage to the chain cleaning auxiliary device 1 due to insecure support from the base plate 14 and the support frame. Simultaneously, the limiting frame 13 also limits movement along the width direction of the track 2, preventing the chain cleaning auxiliary device 1 from shaking and affecting the cleaning of the chain 3.

[0039] The limiting frame 13 includes a connector 131 that is fixedly connected to the bottom of the upper arch plate 11 and extends downward, a support plate 132 that is fixedly connected to the bottom of the connector 131 and extends along the width direction of the upper arch plate 11, and limiting plates 133 disposed at both ends of the extension direction of the support plate 132. The limiting plates 133 are used to hold the two sides of the track 2.

[0040] The connector 131 serves as a connector, the support plate 132 is used to overlap the two sides of the track 2, and the limiting plate 133 is used to abut against the two sides of the track 2 along the width direction.

[0041] The height difference between the lower side of the support plate 132 and the base plate 14 is equal to the height of the track 2. This ensures that when the base plate 14 contacts the track 2, the support plate 132 just overlaps the track 2.

[0042] In this embodiment, there are two limiting frames 13, which are symmetrically arranged on both sides of the first support plate 121, and each limiting frame 13 is located between the first support plate 121 and the second support plate 122.

[0043] The chain cleaning auxiliary device 1 is used as follows:

[0044] When the chain 3 needs cleaning, the tensioning device is loosened, causing the chain 3 to relax.

[0045] Select a suitable track 2 for cleaning, pull the soft chain 3 out of the track 2, insert it into the chain cleaning aid 1, and then place the chain 3 on the chain cleaning aid 1.

[0046] Start the chain drive device 100 to make the chain 3 run slowly. The chain 3 passes over the chain cleaning auxiliary device 1, and the cleaning operator cleans the raised chain 3 thoroughly next to the track 2. Alternatively, the chain drive device 100 can be used in a jogging manner to make the chain 3 pass over in sections, which gives time to clean the chain 3 thoroughly.

[0047] After one section is cleaned, start the chain drive device 100 to pull the next section of chain 3 over, and repeat the operation until the entire chain 3 is cleaned.

[0048] Lift chain 3, remove chain cleaning auxiliary device 1, and tighten the tensioning device to complete the cleaning operation.

[0049] The chain cleaning auxiliary device 1 and chain transmission equipment 100 of this utility model eliminate the cumbersome disassembly, heavy handling and reassembly process of the chain 3 in the past, greatly reducing the cleaning time of the chain 3, saving time and effort, and improving economic efficiency; moreover, the operation of the chain 3 is continuous, which provides conditions for the subsequent development of automated cleaning.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
