[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0031] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0033] After the coal is dug out, a coal mine belt conveyor is needed to transport the excavated coal to the outside, and the belt of the belt conveyor needs to use a roller frame to support the belt. At present, the roller frames on the belt conveyor are mostly fixed roller frames. The rollers on the roller frames can support the belt, but usually many roller frames cannot adjust the distance between them and the belt.

[0034] In the related art, the support and the roller frame are connected by a threaded rod and a threaded sleeve, and the threaded sleeve is rotated to retract the threaded rod into the interior of the threaded sleeve to adjust the length of the threaded rod, and the roller frame is rotated to move away from the belt, so as to facilitate the removal of the roller inside. However, when the existing device is used, it is necessary to manually adjust the threaded sleeve, which is time-consuming and laborious to rotate the threaded sleeve, and it is difficult to accurately adjust the threaded sleeves on both sides to make the rotation angle of the side roller frame consistent, so that greater friction will be generated when contacting the belt, causing the belt to deviate.

[0035] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a coal mine belt conveyor roller frame structure. When the roller on the side roller frame 12 needs to be removed for replacement, it is first necessary to stop the belt conveyor from transporting coal mines, and then connect the double-headed motor 21 to the external power supply and drive the threaded rod 24 to rotate. While rotating, due to the restriction of the rectangular shell 22 on the rectangular rod 23, the threaded rod 24 rotates and drives the rectangular rod 23 to retract into the interior of the rectangular shell 22. At the same time, the connecting rod 25 is used to pull the side roller frame 12 to rotate so that it is flush with the middle roller frame 11 and separated from the bottom of the belt. Then, the roller on the opposite side roller frame 12 is removed. It is only necessary to push the lever 36 to slide inside the groove body 33 and drive the baffle 35 to retract into the interior of the groove body 33 to release the obstruction of the mounting block 32, and then push the roller to move upward so that the mounting block 32 is detached from the inside of the mounting groove 31 to complete the disassembly. When the lever 36 is dragged, after the positioning rod 42 is aligned with the positioning hole 41, the spring 2 43 rebounds and pushes the positioning rod 42 into the positioning hole 41 to fix the position of the baffle 35, so that the lever 36 does not need to be dragged all the time when it is disassembled.
