Description

Technical Field

[0001] This utility model relates to the field of monorail hoisting technology, specifically a monorail hoisting drive gearbox. Background Technology

[0002] A monorail crane is a system that uses a specially designed I-beam suspended above a tunnel as a track. Various types of lifting vehicles are connected together to form a train, which is then pulled along the track by traction equipment. A monorail crane mainly consists of a cab, a power unit (main unit), a drive unit (drive section), a braking system (brake), a load-bearing device (load-bearing vehicle), and a lifting device (lifting beam). The drive reduction gearbox (or drive reducer) is a key component of the power transmission system, primarily used to reduce input speed, increase output torque, and adapt to different driving requirements.

[0003] However, existing monorail hoisting drive gearboxes typically experience rapid oil temperature rises due to the heat generated by gear meshing friction and bearing rotation under continuous heavy load conditions. This leads to a decrease in lubricating oil viscosity, accelerates gear pitting failure, and results in insufficient heat dissipation efficiency in the high-temperature environment downhole. Although lubricants can assist in heat dissipation, separate heat dissipation treatment is required for long-term use. Failure to dissipate heat in a timely manner will affect the performance of the gearbox and may even damage it. Utility Model Content

It solves the problem mentioned in the background art of insufficient heat dissipation efficiency in the high-temperature environment of underground mines. Although lubricants can assist in heat dissipation, they still require separate heat dissipation treatment during long-term use. If heat dissipation is not timely, it will affect the performance of the gearbox and may even cause damage to the gearbox.

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] This embodiment aims to address the problem that relying solely on lubricants for auxiliary heat dissipation results in poor heat dissipation during prolonged use, which can negatively impact the performance of the gearbox.

[0022] Please see Figures 1-3 The single-rail hoisting drive gearbox includes a gearbox body 1, a housing 2 fixedly installed on one side of the gearbox body 1, a connecting pipe 3 fixedly installed on one side of the housing 2, and the connecting pipe 3 is connected to the gearbox body 1. The connecting pipe 3 can facilitate the transmission of cold air to the inside of the gearbox body 1. A cooling component 4 is fixedly installed inside the housing 2, which can cool the surrounding air. A blower 5 is fixedly installed inside the housing 2. A drive frame 6 is slidably connected inside the housing 2. A double-head motor 7 is fixedly installed on one side of the drive frame 6.

A cleaning component 9 is rotatably connected to one side of the filter plate 8. The two ends of the double-head motor 7 can be connected to either the blower 5 or the cleaning component 9.

[0023] In this embodiment: Connecting brackets 21 are fixedly installed on both sides of the housing 2, and the connecting brackets 21 are fixedly connected to the gearbox body 1 by bolts. The connecting brackets 21 are fixed to the gearbox body 1 by bolts, which can fix the housing 2.

[0024] The cooling component 4 includes a frame plate 41 and a semiconductor cooling chip 42 fixed to one side of the frame plate 41. The frame plate 41 is fixedly connected to the housing 2 by bolts. A temperature conducting pipe 43 is provided on one side of the semiconductor cooling chip 42, and one end of the temperature conducting pipe 43 is connected to one side of the housing 2. Several heat sinks 44 are fixedly installed on one side of the semiconductor cooling chip 42. After the semiconductor cooling chip 42 is powered on, the cooling surface will cool and transfer the low temperature to the temperature conducting pipe 43. After heat exchange with the temperature conducting pipe 43, the air is converted into cold air and finally blown into the gearbox body 1 through the connecting pipe 3, thereby dissipating heat inside the gearbox body 1. Compared with the existing heat dissipation structure of the gearbox body 1, the heat dissipation temperature of this heat dissipation structure is lower and the heat dissipation effect is better.

[0025] The blower 5 includes a frame 51 and a fan blade 52 rotatably connected inside the frame 51. A first guide post 53 is fixedly installed on one side of the fan blade 52. The first guide post 53 can serve as a connection. By rotating the fan blade 52, cold air can be blown into the gearbox body 1.

[0026] The drive frame 6 includes a fixed block 61 and an electric push rod 62 fixed to one side of the fixed block 61. The fixed block 61 is fixedly connected to the housing 2. A support frame 63 is fixedly installed at the output end of the electric push rod 62, and the support frame 63 is slidably connected to the housing 2. The dual-head motor 7 is fixedly connected to the support frame 63. The electric push rod 62 can drive the support frame 63 to move, and the position of the dual-head motor 7 can be adjusted by moving the support frame 63.

[0027] Both ends of the dual-head motor 7 are fixedly mounted with shafts 71, and the shafts 71 are slidably connected to the first guide post 53. Limiting posts 72 are fixedly mounted on both sides of the shafts 71, and the limiting posts 72 are slidably connected to the first guide post 53. When it is necessary to dissipate heat from the gearbox body 1, the shafts 71 are inserted into the first guide post 53, and then the limiting posts 72 slide into one end of the first guide post 53. The limiting posts 72 can be limited and connected to the first guide post 53. When the dual-head motor 7 drives the shafts 71 to rotate, it can drive the fan blades 52 to rotate.

[0028] Example 2

[0029] This embodiment aims to address the problem that a lot of dust accumulates on the surface of the filter plate 8 after prolonged use, affecting the filtration effect. This embodiment is an improvement based on Embodiment 1.

[0030] For details, please refer to Figure 4The cleaning component 9 includes a second guide post 91 and fixed plates 92 fixed on both sides of the second guide post 91. The second guide post 91 is rotatably connected to the filter plate 8. The shaft 71 and the limiting post 72 are slidably connected to the second guide post 91. A brush 93 is fixedly connected to one side of the fixed plate 92, and the brush 93 is in contact with the filter plate 8. When the filter plate 8 needs to be cleaned, the shaft 71 is inserted into the second guide post 91, and then the limiting post 72 slides into one end of the second guide post 91. The limiting post 72 can be limited to the second guide post 91. When the dual-head motor 7 drives the shaft 71 to rotate, it can drive the second guide post 91 to rotate, thereby driving the brush 93 to clean the dust attached to the surface of the filter plate 8. Due to gravity, the dust will fall naturally.
