Description
Technical Field
[0001] This utility model belongs to the field of scraper conveyor technology, and in particular relates to an anti-tipping adaptive mechanism for scraper conveyors. Background Technology
[0002] A scraper conveyor is a type of transportation equipment, mainly used in coal mining. It can also be applied to various fields such as metallurgy, building materials, power, and chemicals. It has the advantage that its transportation capacity is not affected by the size and humidity of the cargo, but it also has the disadvantages of high working resistance and high power consumption.
[0003] Nowadays, when scraper conveyors are transporting coal, they are prone to tipping over to the support or coal wall during the transportation process. If a hydraulic cylinder structure is used to support it, the hydraulic cylinder and hydraulic system need to be protected, which greatly increases the complexity of the equipment. At the same time, it also requires workers to perform regular maintenance, which greatly increases the labor intensity and the effect is not good. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that scraper conveyors are prone to tipping over to the support or coal wall during coal transportation. If a hydraulic cylinder structure is used to support it, the hydraulic cylinder and hydraulic system need to be protected, which greatly increases the complexity of the equipment. At the same time, it also requires regular maintenance by workers, which greatly increases the labor intensity and the effect is not good. Therefore, a scraper conveyor anti-tipping adaptive mechanism is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an anti-tipping adaptive mechanism for a scraper conveyor, comprising a scraper conveyor and a connecting pin, wherein a limit plate is fixedly installed on the outer wall of one end of the scraper conveyor, and a push rod is provided at one end of the scraper conveyor via the connecting pin.
[0006] As a further description of the above technical solution:
[0007] The outer wall of the push rod is equipped with a compression spring assembly and a chain-type anti-tipping assembly.
[0008] As a further description of the above technical solution:
[0009] The compression spring assembly includes a housing, the bottom end of which is fixedly mounted on the top surface of the push rod.
[0010] As a further description of the above technical solution:
[0011] A spring rod is fixedly installed on the inner wall of the bottom of the outer casing, and the height of the spring rod is greater than the height of the outer casing.
[0012] As a further description of the above technical solution:
[0013] The chain-type anti-tipping assembly includes a chain, and connecting plates are fixedly installed on the outer wall of the limiting plate and the top surface of the push rod.
[0014] As a further description of the above technical solution:
[0015] A chain pin is fixedly installed on the outer wall of the connecting plate, and the two ends of the chain are movably connected to the chain pin.
[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0017] 1. In this utility model, by setting a compression spring assembly, the spring rod is in contact with the limiting plate set on the scraper conveyor when it is in its natural state. When one end of the scraper conveyor tilts, it compresses the spring rod. When the spring rod is compressed to its limit position, it forms a rigid support, and the scraper conveyor will no longer be able to tilt. In order to ensure that the scraper conveyor has a certain adaptability, the change in the length of the spring rod in its free state and the length in its compressed limit position can be set according to the allowable angle of horizontal tilt of the scraper conveyor. Through this design, the scraper conveyor does not need to use a hydraulic cylinder structure to support it, which greatly reduces the complexity of the equipment. The structure is simple, the cost is low, and there is no need for staff to perform regular maintenance, which greatly reduces the intensity of manual labor and has good performance.
[0018] 2. In this utility model, a chain-type anti-tipping component is provided. The chain is installed on the limiting plate and the push rod at one end of the scraper conveyor through the connecting plate and chain pin respectively. When the scraper conveyor is in a horizontal state, the chain is in a free state and does not affect the normal operation of the scraper conveyor. When the scraper conveyor tilts to the coal wall side, the chain is stretched and the tilt angle of the scraper conveyor is limited. Through this design, the chain connection between the scraper conveyor and the push rod is effectively realized, which not only ensures the connection strength, but also does not interfere with the normal operation of the scraper conveyor, resulting in good performance.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figures 1-5 This utility model provides a technical solution: an anti-tipping adaptive mechanism for a scraper conveyor, including a scraper conveyor 1 and a connecting pin 3. A limit plate 4 is fixedly installed on the outer wall of one end of the scraper conveyor 1. A push rod 2 is provided on one end of the scraper conveyor 1 through the connecting pin 3. A compression spring assembly 5 and a chain-type anti-tipping assembly 6 are provided on the outer wall of the push rod 2.
[0028] The compression spring assembly 5 includes a housing 52, the bottom end of which is fixedly installed on the top surface of the push rod 2, and a spring rod 51 is fixedly installed on the inner wall of the bottom of the housing 52. The height of the spring rod 51 is greater than the height of the housing 52.
[0029] The specific implementation method is as follows: When the spring rod 51 is in its natural state, it is in contact with the limiting plate 4 set on the scraper conveyor 1. When one end of the scraper conveyor 1 tilts, it compresses the spring rod 51. When the spring rod 51 is compressed to the limit position, it forms a rigid support, and the scraper conveyor 1 will not be able to continue to tilt. In order to ensure that the scraper conveyor 1 has a certain adaptability, the change in the length of the spring rod 51 in its free state and the length in its compressed limit position can be set according to the allowable horizontal tilt angle of the scraper conveyor 1.
[0030] The chain-type anti-tipping assembly 6 includes a chain 63. A connecting plate 61 is fixedly installed on the outer wall of the limiting plate 4 and the top surface of the push rod 2. A chain pin 62 is fixedly installed on the outer wall of the connecting plate 61. The two ends of the chain 63 are movably connected to the chain pin 62.
[0031] The specific implementation method is as follows: the chain 63 is installed on the limiting plate 4 and the push rod 2 at one end of the scraper conveyor 1 through the connecting plate 61 and the chain pin 62 respectively. When the scraper conveyor 1 is in a horizontal state, the chain 63 is in a free state and does not affect the normal operation of the scraper conveyor 1. When the scraper conveyor 1 tilts to the coal wall side, the chain 63 is stretched by force to limit the tilt angle of the scraper conveyor 1.
[0032] Working principle: When the spring rod 51 is in its natural state, it is in contact with the limiting plate 4 set on the scraper conveyor 1. When one end of the scraper conveyor 1 tilts, it compresses the spring rod 51. When the spring rod 51 is compressed to its limit position, it forms a rigid support, and the scraper conveyor 1 will no longer be able to tilt. In order to ensure that the scraper conveyor 1 has a certain adaptability, the change in the length of the spring rod 51 in its free state and the length in its compressed limit position can be set according to the allowable horizontal tilt angle of the scraper conveyor 1. The chain 63 is installed on the limiting plate 4 and the push rod 2 set at one end of the scraper conveyor 1 through the connecting plate 61 and the chain pin 62, respectively. When the scraper conveyor 1 is in a horizontal state, the chain 63 is in a free state and does not affect the normal operation of the scraper conveyor 1. When the scraper conveyor 1 tilts to the coal wall side, the chain 63 is stretched and the tilt angle of the scraper conveyor 1 is limited.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
