Description

Technical Field

[0001] The utility model belongs to the technical field of mining machinery, and particularly relates to an anti-deviation structure for the tail of a conveyor and a conveyor. Background Art

[0002] The conveyor is a main equipment for fully mechanized coal mining transportation in coal mines. Its function is to transfer the coal transported by the scraper conveyor to the belt conveyor after raising it from the bottom of the roadway. After a cut of coal is completed, the pushing beam of the support uses the pushing and pulling oil cylinder to push the scraper conveyor forward by a cycle distance. After pushing it over, the hydraulic support uses the scraper conveyor as a fulcrum to pull itself forward by a cycle. The conveyor moves longitudinally and integrally by stepping self-shifting, thus completing the coal mining work.

[0003] In a fully mechanized coal mining face, the conveyor transfers the coal of the scraper conveyor to the roadway belt conveyor. It is a heavy-duty scraper conveyor that can move longitudinally and integrally. Due to its large conveying capacity, high load-bearing capacity, and long working face, etc., the tail of the conveyor will deviate when it moves longitudinally and integrally. Therefore, the coal spills outside when it is transferred from the scraper conveyor to the tail of the conveyor, and the coal return at the unloading section and the tail of the conveyor is serious.

[0004] Based on this, the existing technology needs to be further developed. Summary of the Utility Model

[0005] In view of various deficiencies of the existing technology, an anti-deviation structure for the tail of a conveyor and a conveyor are provided to solve the technical problem that the tail of the conveyor is prone to deviation during stepping self-shifting in the existing technology.

[0006] To achieve the above object, the utility model provides the following technical solutions:

[0007] In the first aspect, the utility model provides an anti-deviation structure for the tail of a conveyor, including a connecting plate and a pin shaft assembly. The connecting plate is fixedly connected to the tail of the conveyor, the pin shaft assembly is connected to the connecting plate, and the pin shaft assembly is used to connect a telescopic mechanism, and the telescopic mechanism moves synchronously with the pushing and pulling oil cylinder of the conveyor.

[0008] This technical solution is further set as follows: the side bottom plate of the tail of the conveyor extends a wing plate in the direction away from the tail of the conveyor. The connecting plate and the wing plate are stacked from top to bottom, and the connecting plate is fixedly connected to the wing plate.

[0009] This technical solution is further set as follows: the connecting plate and the wing plate are welded.

[0010] This technical solution is further set as follows: the wing plate and the side bottom plate are integrally formed.

[0011] This technical solution is further configured such that the pin shaft assembly includes a pin shaft and a pin. One end of the telescopic mechanism is sleeved on the pin shaft. One end of the pin shaft is connected to the connecting plate. A connecting ear plate extends from the other end of the pin shaft. The pin passes through the connecting ear plate and is connected to the connecting plate. A pin hole for connecting the pin is formed in the connecting plate.

[0012] This technical solution is further configured such that the telescopic mechanism is a single-body oil cylinder. One end of the telescopic mechanism is connected to the pin shaft assembly, and the other end of the telescopic mechanism is fixedly arranged on the coal wall side.

[0013] This technical solution is further configured such that a plurality of connecting plates are provided. The pin shaft assemblies are arranged in one-to-one correspondence with the connecting plates, and the plurality of connecting plates are symmetrically arranged on both sides of the tail of the transfer machine.

[0022] To enable those skilled in the art to better understand the technical solution of the present utility model, the following clearly and completely describes the technical solution of the present utility model in conjunction with the accompanying drawings of the present utility model. Based on the embodiments in this application, other similar embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application. In addition, the directional terms mentioned in the following embodiments, such as "up", "down", "left", "right", etc. are only with reference to the directions of the accompanying drawings. Therefore, the directional terms used are for illustration rather than to limit the present invention.

[0023] The following further describes the present utility model in conjunction with the accompanying drawings and preferred embodiments.

[0024] According to an embodiment of the present utility model, a structure for preventing the tail of a conveyor loader from deviating is provided. Please refer to Figures 1 to 4 , which includes: a connecting plate 4 and a pin shaft assembly 5. The connecting plate 4 is fixedly connected to the tail 1 of the conveyor loader, the pin shaft assembly 5 is connected to the connecting plate 4, and the pin shaft assembly 5 is used to connect the telescopic mechanism. The telescopic mechanism moves synchronously with the push-pull oil cylinder of the conveyor loader.

[0025] It should be noted that when the conveyor loader moves forward step by step, the body of the conveyor loader moves forward as a whole under the action of the push-pull oil cylinder, and the tail 1 of the conveyor loader moves synchronously with the body under the action of the telescopic mechanism. By providing the connecting plate 4 and the pin shaft assembly 5, a reliable connection is achieved for the telescopic mechanism, preventing the tail 1 of the conveyor loader from deviating when the conveyor loader moves forward step by step, and thus solving the problem of serious coal return at the unloading section of the conveyor loader and at the tail 1 of the conveyor loader. The structure is simple and reliable, greatly reducing the time for workers to clean the coal return, reducing the labor intensity, and improving the work efficiency.

[0026] In the structure for preventing the tail of the conveyor loader from deviating in this embodiment, a wing plate 3 extends from the side bottom plate 2 of the tail 1 of the conveyor loader in a direction away from the tail 1 of the conveyor loader. The wing plate 3 is integrally formed with the side bottom plate 2. The connecting plate 4 and the wing plate 3 are stacked from top to bottom, and the connecting plate 4 is fixedly connected to the wing plate 3.

[0027] To ensure the reliable connection between the connecting plate 4 and the tail 1 of the conveyor loader, a part of the side bottom plate 2 is widened to form the wing plate 3, increasing the contact area between the connecting plate 4 and the tail 1 of the conveyor loader, which is convenient for connecting the two.

[0028] In the structure for preventing the tail of the conveyor loader from deviating in this embodiment, the connecting plate 4 and the wing plate 3 are welded. Welding has a higher connection strength compared to connection methods such as threaded connection, further improving the connection reliability between the connecting plate 4 and the wing plate 3, thereby providing a strong support for the movement of the telescopic mechanism.

[0029] In the anti-deviation structure of the tail of the transfer machine in this embodiment, the telescopic mechanism is a single cylinder. One end of the telescopic mechanism is connected to the pin shaft assembly 5, and the other end of the telescopic mechanism is fixedly arranged on the coal wall side. Compared with cylinders and electric cylinders, the thrust and torque output by the oil cylinder are greater, which is more suitable for large machinery such as transfer machines.

[0030] In the anti-deviation structure of the tail of the transfer machine in this embodiment, the pin shaft assembly 5 includes a pin shaft 6 and a pin 8. The telescopic mechanism is connected to the pin shaft 6. Specifically, one end of the telescopic mechanism is sleeved on the pin shaft 6. One end of the pin shaft 6 is connected to the connecting plate 4, and an installation ear extends from the other end of the pin shaft 6. The pin 8 passes through the installation ear and is connected to the connecting plate 4. A pin hole for connecting the pin 8 is provided on the connecting plate 4.

[0031] It should be noted that the single cylinder is connected to the pin shaft 6 through its connecting earring. After the pin shaft 6 is connected to the single cylinder, the pin 8 is passed through the installation ear and connected to the connecting plate 4.

[0032] In the anti-deviation structure of the tail of the transfer machine in this embodiment, a plurality of connecting plates 4 are provided. The pin shaft assemblies 5 are arranged in one-to-one correspondence with the connecting plates 4, and the plurality of connecting plates 4 are symmetrically arranged on both sides of the tail 1 of the transfer machine. A plurality of pin shaft assemblies 5 can be connected to the single cylinder, so as to ensure the uniform movement of the tail 1 of the transfer machine. In addition, if one of the single cylinders fails, the other single cylinders can still maintain part of the functions to a certain extent, improving the fault tolerance rate.

[0033] According to an embodiment of the present invention, a transfer machine is provided. Please refer to Figures 1 to 4 , which includes the above anti-deviation structure of the tail of the transfer machine.

[0034] The present invention has been described in detail above.
