Description

Technical Field

[0001] This utility model relates to a coal mine electromechanical transport transmission device, belonging to the technical field of conveying equipment. Background Technology

[0002] Coal mine electromechanical transportation transmission devices mainly include belt conveyors, scraper conveyors, and mining locomotives, and their structural composition varies depending on the type of equipment.

[0003] Belt conveyors are widely used due to their excellent continuous conveying function. For example, a coal mine electromechanical transport transmission device disclosed in CN213801706U and a coal mine electromechanical transport transmission device disclosed in CN202121312526.5 both belong to the category of belt conveyors.

[0004] The technical solutions disclosed in the aforementioned patent documents still have the following technical problems, based on practical experience:

[0005] When in use, its conveying distance is fixed, resulting in a single material drop point. This makes it unsuitable for the dynamic needs of the working face to advance or retreat, which is not conducive to the distribution and accumulation of coal and affects the flexibility of the equipment.

[0006] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0007] This utility model addresses the shortcomings of the prior art by providing a coal mine electromechanical transport transmission device that can flexibly adjust the effective conveying length of the conveyor belt as needed, improving its flexibility and ensuring that the conveyor belt is always taut, thus guaranteeing stable operation.

[0008] To solve the above technical problems, the present invention adopts the following technical solution:

[0009] A coal mine electromechanical transport transmission device includes a driving roller, a driven roller, and a pressure roller arranged in a triangular shape. A conveyor belt is wound around the driving roller, the driven roller, and the pressure roller. The driving roller and the driven roller are rotatably mounted on opposite outer ends of a transverse telescopic arm. A longitudinal telescopic arm is fixedly connected to the middle of the bottom of the transverse telescopic arm and is perpendicular to it. The pressure roller is rotatably mounted on the bottom end of the longitudinal telescopic arm.

[0010] The lateral telescopic arm includes a hollow lateral fixed arm, and both ends of the lateral fixed arm are provided with hollow lateral guide arms; the longitudinal telescopic arm includes a hollow longitudinal fixed arm, and the lower end of the longitudinal fixed arm is equipped with a hollow longitudinal guide arm.

[0011] Furthermore, there are two lateral telescopic booms, which are arranged side by side.

[0012] Furthermore, there are two longitudinal telescopic arms, which are arranged side by side.

[0013] Furthermore, a double-outlet hydraulic cylinder is installed between the two transverse guide arms. The double-outlet hydraulic cylinder is installed in the middle of the inner cavity of the transverse fixed arm through a fixed seat. The double-outlet hydraulic cylinder has two symmetrically arranged extension shafts, and the outward ends of the two extension shafts are connected to the transverse guide arm through pins.

[0014] Furthermore, slip rings are fixedly installed on the inner sides of both ends of the transverse fixed arm, and the slip rings are slidably connected to the outer wall of the transverse guide arm; slip rings are fixedly installed on the outer sides of the opposite inner ends of the transverse guide arm, and the slip rings are slidably connected to the inner wall of the transverse fixed arm.

[0015] Furthermore, the driving roller and the driven roller are rotatably mounted on the end of the transverse guide arm away from the transverse fixed arm via bearing seats.

[0016] Furthermore, a single-output hydraulic cylinder is installed inside the longitudinal fixed arm and the longitudinal guide arm. The head of the single-output hydraulic cylinder is connected to the longitudinal guide arm via a pin, and the tail of the single-output hydraulic cylinder is connected to the longitudinal fixed arm via a rotating shaft.

[0017] Furthermore, the pressure roller is rotatably mounted on the bottom end of the longitudinal guide arm via a bearing seat.

[0018] Furthermore, one end of the drive roller is connected to a geared motor.

[0019] Furthermore, the lateral fixing arm is installed on the top of the frame, and a set of omnidirectional wheels is installed on one side of the bottom of the frame, while a set of directional wheels is installed on the other side of the bottom.

[0020] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0021] The dual-output hydraulic cylinder in this invention provides power for the sliding of the transverse guide arm along the transverse fixed arm. When the dual-output hydraulic cylinder extends or retracts, it causes the driving roller and the driven roller to move in opposite directions or towards each other, thereby extending or shortening the effective conveying length of the conveyor belt and improving the flexibility of the device. The single-output hydraulic cylinder provides power for the sliding of the longitudinal guide arm along the longitudinal fixed arm, causing the pressure roller to rise or fall, which can keep the conveyor belt in a taut state and ensure stable operation.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0030] The active roller 1 and the driven roller 2 are rotatably mounted on the opposite outer ends of the transverse telescopic arm 4. A longitudinal telescopic arm 5, which is perpendicular to the transverse telescopic arm 4, is fixedly connected to the middle position of the bottom of the transverse telescopic arm 4. The pressure roller 3 is rotatably mounted on the bottom end of the longitudinal telescopic arm 5.

[0034] The dual-output hydraulic cylinder 43 is installed in the middle of the inner cavity of the transverse fixed arm 41 via a fixed base 44. The dual-output hydraulic cylinder 43 has two symmetrically arranged extension shafts. The outward ends of the two extension shafts are connected to the transverse guide arm 42 via pins. The dual-output hydraulic cylinder 43 provides power for the transverse guide arm 42 to slide along the transverse fixed arm 41.

[0035] Slip rings are fixedly installed on the inner sides of both ends of the transverse fixed arm 41, and the slip rings are slidably connected to the outer wall of the transverse guide arm 42; slip rings are fixedly installed on the outer sides of the opposite inner ends of the transverse guide arm 42, and the slip rings are slidably connected to the inner wall of the transverse fixed arm 41. The slip rings are used to ensure the smooth extension and retraction of the transverse guide arm 42.

[0036] The driving roller 1 and the driven roller 2 are rotatably mounted on the end of the transverse guide arm 42 away from the transverse fixed arm 41 via bearing seats.

[0037] The longitudinal telescopic arm 5 includes a hollow longitudinal fixed arm 51, and a hollow longitudinal guide arm 52 is installed inside the lower end of the longitudinal fixed arm 51.

[0039] One end of the drive roller 1 is connected to the geared motor 7, and the geared motor 7 drives the drive roller 1, thereby driving the conveyor belt 8 to rotate.

[0040] The horizontal fixed arm 41 is installed on the top of the frame 6, and a set of universal wheels and a set of directional wheels are installed on one side of the bottom of the frame 6.

[0041] The specific working principle of this utility model is as follows:

[0043] When the double-output shaft hydraulic cylinder 43 extends, the single-output shaft hydraulic cylinder 53 retracts, causing the driving roller 1 and the driven roller 2 to move in opposite directions, while the pressure roller 3 rises, thereby extending the effective conveying length of the conveyor belt 8 and keeping the conveyor belt 8 in a taut state at all times.

[0044] When the double-output shaft hydraulic cylinder 43 retracts, the single-output shaft hydraulic cylinder 53 extends, causing the driving roller 1 and the driven roller 2 to move in opposite directions, while the pressure roller 3 descends, thereby shortening the effective conveying length of the conveyor belt 8 and keeping the conveyor belt 8 in a taut state at all times.
