Description

Technical Field

[0001] This utility model belongs to the field of cable chain technology, and in particular relates to an intermediate cover plate for a cable chain and a heavy-duty cable chain. Background Technology

[0002] Cable chains are suitable for use in reciprocating motion applications. They can provide traction and protection for built-in cables, oil pipes, air pipes, water pipes, etc., while making the overall machine look more aesthetically pleasing. Cable chains are mostly composed of several links that can be connected together in a relatively rotatable manner.

[0003] In certain special applications, such as the metallurgical industry, heavy-duty cable chains with long travel distances (usually tens of meters) are required to protect wires or pipes. During long-distance dragging, existing heavy-duty cable chains inevitably experience friction between the upper and lower cable chains. Due to the large weight of the heavy-duty cable chains and the fact that they are often used in environments with strong acids and high temperatures, wear is easily caused at the connection between the chain plates and the intermediate cover plates, leading to the detachment of the intermediate cover plates from the chain plates and rendering them unusable. This results in a short service life. Utility Model Content

[0004] The purpose of this utility model is to provide a middle cover plate for a cable chain and a heavy-duty cable chain, so as to solve the problem that conventional heavy-duty cable chains in the prior art have a short service life due to the middle cover plate and chain plate falling off at the connection.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] In a first aspect, a middle cover plate for a cable chain is provided, comprising a cover plate body, wherein:

[0007] The cover plate body is provided with mounting parts on the first surface at both ends along its own length direction, and the two mounting parts are respectively detachably mounted on the inner side of two spaced chain plates.

[0008] The cover plate body has protrusions on the second surfaces at both ends along its length. The protrusions protrude from the second surfaces of the cover plate body and have horizontal surfaces that slide in contact with other components. The first surface and the second surface are opposite surfaces.

[0009] Furthermore, the working surface of the protrusion includes a horizontal plane, a first guide slope, and a second guide slope. The horizontal plane extends along the length direction perpendicular to the cover plate body. The first guide slope and the second guide slope are located at opposite ends of the horizontal plane along its own length direction. The first end of the first guide slope and the second guide slope that connect to the horizontal plane is higher than the second end.

[0010] Furthermore, the connection between the first guide slope and the second guide slope and the horizontal plane is a rounded transition.

[0011] Furthermore, the working surface of the protrusion is an arc surface.

[0012] Furthermore, the sidewall at the end of the cover plate body is provided with a vertically extending extension, and the top of each extension is provided with a guide slope.

[0013] Furthermore, the mounting part is a mounting groove formed on the first surface. A first snap-fit ​​platform extends from the cover plate body toward the mounting groove. A mounting component is provided on the chain plate. Each mounting component has a second snap-fit ​​platform protruding outward on both sides. The second snap-fit ​​platform is provided corresponding to the first snap-fit ​​platform. The second snap-fit ​​platform snaps onto the corresponding first snap-fit ​​platform to install the mounting component in the mounting groove, thereby detachably mounting the cover plate body onto the corresponding chain plate.

[0014] Furthermore, the mounting component is provided with a snap-fit ​​protrusion, and the cover plate body is provided with a snap-fit ​​groove that is connected to the mounting groove. The snap-fit ​​protrusion is adapted to the snap-fit ​​groove. When the cover plate body is installed on the chain plate, the snap-fit ​​protrusion passes through the snap-fit ​​groove.

[0015] Furthermore, at least one side of the middle part of the cover plate body is provided with a weight-reducing groove, and a number of connecting blocks are arranged at intervals in the weight-reducing groove.

[0016] Furthermore, the protrusion and the cover plate body are an integral structure.

[0017] In a second aspect, a heavy-duty cable chain is provided, the cable chain comprising a plurality of cable chain segment units, each of the cable chain segment units comprising the aforementioned intermediate cover plate of the cable chain.

[0018] Compared with the prior art, the beneficial effects of the intermediate cover plate of the cable chain and the heavy-duty cable chain are as follows:

[0019] 1) By setting protrusions on the second surface at both ends of the cover plate body, the upper protrusion and the lower protrusion come into contact and rub against each other during the sliding process of the cable chain, which will not wear down the cover plate body, significantly improving the connection strength of the cover plate body and greatly improving the service life of the cover plate body.

[0020] 2) By setting a first guide ramp and a second guide ramp at both ends of the horizontal plane along the first horizontal direction, the movement of the cable chain is guided during dragging, preventing jamming and ensuring normal dragging of the cable chain. Attached Figure Description

[0027] Please see Figures 1 to 3As shown, in this embodiment, a cable chain intermediate cover plate includes a cover plate body 10, wherein: a mounting portion 20 is provided on the first surface 11 at both ends of the cover plate body 10 along its own length direction, and the two mounting portions 20 are respectively detachably mounted on the inner side surfaces of two spaced-apart chain plates; a protrusion 30 is provided on the second surface 12 at both ends of the cover plate body 10 along its own length direction, the protrusion 30 protrudes from the second surface 12 of the cover plate body 10, and the protrusion 30 has a horizontal surface 31 that slides in contact with other components, and the first surface 11 and the second surface 12 are opposite surfaces.

[0028] Specifically, the protrusion 30 is a boss with a preset width.

[0029] It should be noted that: the second surface 12 at both ends of the cover plate body 10 along its own length direction is provided with protrusions 30. The protrusions 30 at both ends are located at the connection between the cover plate body 10 and the chain plate. When the drag chain slides, the upper protrusion 30 will contact and rub against the lower protrusion 30, and will not wear down the connection between the cover plate body 10 and the chain plate.

[0030] As can be seen, by providing protrusions 30 protruding from the second surface 12 at both ends of the cover body 10, the upper protrusion 30 and the lower protrusion 30 come into contact and rub against each other during the sliding process of the cable chain, which will not wear down the cover body 10, significantly improving the connection strength of the cover body 10 and greatly improving the service life of the cover body 10.

[0031] In one embodiment, the working surface of the protrusion 30 includes a first guide slope 32 and a second guide slope 33. The horizontal plane 31 extends along the length direction perpendicular to the cover plate body 10. The first guide slope 32 and the second guide slope 33 are located at the two ends of the horizontal plane 31 along its own length direction, respectively. The first end of the first guide slope 32 and the second guide slope 33 that connects to the horizontal plane 31 is higher than the second end.

[0032] As can be seen, by setting the first guide slope 32 and the second guide slope 33 at both ends of the horizontal plane 31 along the first horizontal direction, the movement of the cable chain is guided during dragging, preventing jamming and ensuring normal dragging of the cable chain.

[0033] In one implementation, the connection between the first guide slope 32 and the second guide slope 33 and the horizontal surface 31 is made of a rounded transition.

[0034] In one embodiment, the working surface of the protrusion 30 is an arc surface.

[0035] In one embodiment, a vertically extending extension 34 is provided on the side wall of the end of the cover plate body 10, and a guide slope is provided at the top of each extension 34.

[0036] Specifically, the extension portion 34 has a concave arc surface.

[0037] It can be seen that by setting the vertically extending extension 34, the contact area between the cover plate body 10 and the chain plate is increased, and the connection strength with the chain plate is further improved.

[0038] In one embodiment, the mounting part 20 is a mounting groove formed on the first surface 11. A first locking platform 21 extends from the cover plate body 10 toward the mounting groove. A mounting component is provided on the chain plate. Each mounting component has a second locking platform protruding outward on both sides. The second locking platform is provided corresponding to the first locking platform 21. The second locking platform is locked onto the corresponding first locking platform 21 to install the mounting component in the mounting groove, thereby detachably mounting the cover plate body 10 onto the corresponding chain plate.

[0039] As can be seen, by engaging the first and second locking platforms, the mounting components are installed in the mounting slots, and the cover plate body 10 is then installed on the corresponding chain plate. The locking method is simple and the installation is secure.

[0040] In one embodiment, the mounting component is provided with a snap-fit ​​protrusion, and the cover plate body 10 is provided with a snap-fit ​​groove 13 through it. The snap-fit ​​groove 13 is connected to the mounting groove, and the snap-fit ​​protrusion is adapted to the snap-fit ​​groove 13. When the cover plate body 10 is installed on the chain plate, the snap-fit ​​protrusion passes through the snap-fit ​​groove 13.

[0041] In one embodiment, a weight-reducing groove 40 is provided on at least one side of the middle part of the cover plate body 10 along the first direction, and a plurality of connecting blocks 41 are provided at intervals in each weight-reducing groove 40.

[0042] It can be seen that by opening a weight-reducing groove 40 in the middle of the cover plate body 10, the weight of the cover plate body 10 can be reduced while ensuring the strength of the cover plate body 10.

[0043] Specifically, the cover plate body 10 has weight-reducing grooves 40 on both sides along its length in the middle.

[0044] Based on the aforementioned intermediate cover plate of the cable chain, a heavy-duty cable chain is provided, which includes a plurality of cable chain section units, each cable chain section unit including the aforementioned intermediate cover plate of the cable chain.

[0045] When the cable chain slides, the protrusion 30 of the upper cover body 10 and the protrusion 30 of the lower cover body 10 come into contact and rub against each other. After long-term use, the protrusion 30 of the cover body 10 will wear down, but will not wear down the cover body 10 and the connection of the chain plate, thus improving the service life of the cover body 10.

[0046] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above examples. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
