Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to a lightweight double-pitch conveying chain. Background Art

[0002] As a kind of commonly used transmission chain, double-pitch conveyor chain means that the spacing between the inner and outer plates of the chain links is different. This kind of chain can reduce impact and noise, improve transmission stability and service life, and can run for a long time without lubrication. Therefore, it has broad application prospects in industrial production lines and automated production equipment.

[0003] At present, the double-pitch conveyor chain in the prior art is usually arranged at both ends of a conveying structure such as a mesh chain or a chain plate for conveying materials, and its connection method is mostly connected by pins on both sides, so that the double-pitch chain is exposed on the outside, and due to the structural characteristics of the double-pitch chain itself, its pitch is large, and the distance between adjacent rollers is large. For example, when conveying media such as ore, it is often difficult to avoid that media of similar size such as ore remain or get stuck between the rollers on the chain during the conveying process, which can easily cause the chain to deform or even break, affecting the conveying efficiency. At the same time, common double-pitch chains are often not provided with a protective structure. The protective structure designed often acts on the conveying structure itself, thereby only indirectly protecting the chain, and the protective effect of the connection is also less than ideal due to the structural limitations of the conveying structure.

DETAILED DESCRIPTION

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0020] See also Figure 1 The present embodiment relates to a lightweight double-pitch conveyor chain, comprising outer links 1 and inner links 2 which are arranged in a staggered manner, wherein rollers 100 are rotatably provided on the outer links 1 and the inner links 2 and are connected by a plurality of pins 3, and cover plates 4 are provided on the chain plates 101 on both sides of the outer links 1 and the inner links 2, wherein the cover plates 4 are placed on one side of the outer links 1 and the inner links 2 and adjacent cover plates 4 are connected by telescopic sleeves 5.

[0021] Specifically in this embodiment, see Figure 1 As shown, compared with the traditional double-pitch chain structure, this double-pitch conveyor chain has a cover plate 4 of a matching size connected to one side of the outer link 1 and the inner link 2. At the same time, a telescopic sleeve 5 is connected between the adjacent cover plates 4 placed on one side of the outer link 1 and the inner link 2. Specifically, during the rotation of this double-pitch conveyor chain connected on both sides of the conveying structure, the mutually hinged outer link 1 and the inner link 2 rotate at an appropriate angle, and drive the cover plates 4 connected thereto to deviate at an appropriate angle without interfering with each other between adjacent cover plates 4. At the same time, during the rotation of the cover plates 4, the telescopic sleeves 5 connected between the adjacent cover plates 4 can be telescoped to a certain length, so that The upper surface of this double-pitch conveyor chain can play a certain protective role under the action of the cover plate 4 and its telescopic sleeve 5, and no leakage will occur when connected to its conveying structure. At the same time, the protective structure arranged on its conveying structure can further enhance the protective effect, so that it is not affected by its conveying medium, can be suitable for different use environments and use requirements, has high adaptability, and can further reduce the probability of deformation or even damage of this double-pitch conveyor chain due to residual conveying medium or jamming between the rollers 100 of the chain, thereby improving stability during use and further improving durability, saving certain use and maintenance costs.

[0022] The cover plate 4 is connected by the springs 6 arranged on the chain plates 101 on both sides of the outer link 1 and the inner link 2, and is placed on one side of the outer link 1 and the inner link 2 to slide relative to each other. The cover plate 4 connected in this way has a certain shock-absorbing and buffering effect. Specifically, an appropriate gap is left between the cover plate 4 and the outer link 1 and the inner link 2, and the size of the cover plate 4 is such that the gap size is not sufficient to affect the protective effect. When the conveying medium of the conveying structure falls onto the cover plate 4 during the conveying process, the cover plate 4 slides downward under the pressure of the conveying medium through the springs 6 arranged on the chain plates 101 on both sides of the outer link 1 and the inner link 2, and the cover plate 4 has a certain reverse force while sliding, which can play a certain protective role for this chain and also avoid direct contact between the conveyed impurities and the chain during the conveying process or due to external factors, and can play a certain buffering and shock-absorbing role through the cover plate 4 during the falling process of the conveying medium, further improving the use stability and conveying efficiency of this double-pitch conveying chain, and appropriately extending the service life.

[0023] See also Figure 2-3The cover plate 4 disposed on one side of the outer link 1 is connected through the lifting assembly 7 disposed on the chain plates 101 on both sides of the outer link 1. The bottom of the cover plate 4 disposed on one side of the outer link 1 is provided with a first slide groove 41. The chain plates 101 on both sides of the outer link 1 are provided with a connecting shaft 1012 and a second slide groove 1011. The lifting assembly 7 adopts a scissor-type lifting structure, which includes a lifting rod 71, a first connecting seat 72 and a second connecting seat 73. The lifting rod 71 is provided with two groups and is diagonally rotated on the connecting shaft 1012. The first connecting seat 72 and the second connecting seat 73 are hingedly provided with two ends of the lifting rod 71 and are respectively slidably provided on the first sliding groove 41 at the bottom of the cover plate 4 and the second sliding groove 1011 on the chain plates 101 on both sides of the outer link 1. The second connecting seats 73 slidably provided in the second sliding groove 1011 on the chain plates 101 of the outer link 1 are connected by the tension spring 8 and slide relatively. Specifically, the second connecting seats 73 on both sides of the second sliding groove 1011 on the chain plates 101 of the outer link 1 are moved along the second sliding groove 1011 to the middle of the chain plate 101 under the action of the tension spring 8. The lifting rods 71 ​​hinged at one end thereof are driven to rotate relatively on the connecting shaft 1012 provided on the chain plate 101 during the sliding process, thereby driving the first connecting seat 72 hinged at the other end of the two sets of lifting rods 71 ​​to slide relatively along the first sliding groove 41 provided at the bottom of the cover plate 4 on one side of the outer chain link 1. At the same time, the relative rotation of the two sets of lifting rods 71 ​​can drive the cover plate 4 to move upward, thereby leaving a certain gap with the outer chain link 1. When the conveying medium of the conveying structure falls onto the cover plate 4 during the conveying process, The cover plate 4 placed on one side of the outer link 1 moves in a manner opposite to the above process under the pressure of the conveying medium. For details, please refer to the scissor-type lift structure. The lifting component 7 adopting the scissor-type structure can make the cover plate 4 placed on one side of the outer link 1 have a better supporting effect. At the same time, the staggered distribution structure of the cover plate 4 placed on the side of the inner chain plate 101 through the spring 6 link can further enhance the buffering and shock absorbing performance of the cover plate 4, reduce the impact of the conveying medium on the chain, and further improve the stability and reliability of this chain during rotation.

[0024] The outer sides of the tension spring 8 and the spring 6 are both covered with a matching protective sleeve 110, which can be seen in Figure 2 or Figure 4 The protective cover 110 can provide a certain degree of protection for the tension spring 8 and the spring 6, thereby preventing the conveying medium or external factors from causing deformation, jamming or even damage to the spring 6 or the tension spring 8, further improving the stability of the spring 6 or the tension spring 8 during the chain rotation process and during its use, and extending its service life.

[0025] The top of the cover plate 4 is also provided with a mounting seat 9 for connecting the conveying structure. Figure 4As shown, the mounting seat 9 can be arranged with a clamp or a clamping ring structure, which can facilitate the clamping connection between the double-pitch conveying chain placed at both ends of the conveying structure and the axis of the conveying structure such as its mesh chain or chain plate 101, which is convenient for installation, use and disassembly and maintenance, and has high adaptability and practicality. At the same time, the connection structure of the cover plate 4 and this chain can make the conveying structure such as the mesh chain or chain plate 101 have a certain buffering and shock-absorbing effect, improve the stability during use, reduce the degree of damage to the conveying structure caused by the conveying medium, and meet different conveying needs.

[0026] The mounting seat 9 is rotatably set on the top of the cover plate 4. The rotatable setting and the mounting seat 9 on the top of the cover plate 4 can be offset and adjusted at a certain angle according to the installed conveying structure such as the mesh chain or chain plate 101, so as to have a certain buffering and shock-absorbing effect on the stress generated by the conveying medium on the conveying structure during the conveying process, reduce the degree of damage, and facilitate the adaptation and installation of different conveying structures, meet different installation and use requirements, and improve adaptability.

[0027] The cover plate 4 is provided with a hollow structure in the middle, such as Figure 4 As shown in the figure, the cover plate 4 with a hollow structure in the middle can further reduce the weight of the cover plate while ensuring that its structure has a certain stability, so that the double-pitch conveyor chain itself has a lighter weight compared to the conventional short-distance chain, and the weight is further reduced, thereby ensuring the operating stability while reducing the vibration, noise and energy loss generated during the operation.

[0028] The lifting assembly 7 is installed on the two side chain plates 101 of the outer link 1 through a detachable structure. The two side chain plates 101 of the outer link 1 are also provided with a second connecting shaft 1013. The cover plate 4 is provided with a split structure and is connected to the lifting assembly 7 through a detachable structure. Figure 4 As shown, the lifting rod 71 is rotatably arranged on the connecting shaft 1012, the first connecting seat 72 and the second connecting seat 73 in a plug-in manner. At the same time, the first connecting seat 72 is connected to the cover plate 4 by bolts. The cover plate 4 arranged in a split structure can be connected by a plug-in structure. Specifically, when deformation or even damage occurs and needs to be disassembled, repaired and replaced, the cover plate 4 arranged in a split structure and the lifting assembly 7 connected thereto can be easily disassembled, and at the same time, the second connecting shaft 1013 arranged on both sides of the outer chain link 1 can be installed and fixed in the opposite direction, and the chain plate 101 on the outer chain link 1 can also be rotated in the matching direction to facilitate use and adjustment, easy maintenance and replacement, and improve stability and flexibility in use.
