[0002] Inspection robots are currently widely used in all walks of life. They not only save a lot of manpower, but are also safer and more convenient to operate.

[0003] However, the existing domestic hanging rail inspection robots cannot climb steep slopes with a gradient greater than 30 degrees, such as in work environments such as monitoring conveyor belts in the coal mining industry, so it is necessary to design a new type of drive mechanism. Summary of the invention

[0004] In view of the above problems existing in the prior art, the main purpose of the present invention is to provide a side-mounted rail-type driving mechanism.

[0005] The technical solution of the present invention is as follows: a side-mounted rail-mounted drive mechanism comprises a power transmission gear train, an outer side of the power transmission gear train is fixedly connected to a motor, an output end of the motor is installed with a reducer, an output shaft of the reducer is fixedly connected to a tensioning sleeve, an outer side of the tensioning sleeve is fixedly connected to a gear, and the gear is rotatably connected to the top of the power transmission gear train, and two other groups of gears are rotatably connected on both sides of the top of the power transmission gear train away from the gear, and transmission gears are respectively arranged between the other two groups of gears and one of the groups of gears, and the gears are respectively meshed with the transmission gears, and the outer lower parts of the tensioning sleeves inside the other two groups of gears are fixedly connected with rubber-coated power wheels, and a first deep groove ball bearing and a second deep groove ball bearing are respectively fixedly connected to the outer sides of the rubber-coated power wheel and located on the outside of the tensioning sleeve.

[0006] As a preferred embodiment, the bottom of the power transmission gear train is fixedly connected to a base, the top of the base is fixedly connected to a fixing frame on a side away from the power transmission gear train, and a tensioning wheel matching the rubber-coated power wheel is arranged on the upper part of the fixing frame.

[0007] As a preferred implementation, a rotating column is rotatably connected between the base at the bottom of the power transmission gear train and the fixed frame, and bottom auxiliary wheels are fixedly connected to both sides of the outside of the rotating column.

[0008] As a preferred embodiment, a fixing block is fixedly connected to the top of the power transmission gear train and located between the other two sets of gears, and an outer end of the fixing block is rotatably connected to a top supporting wheel.

[0009] As a preferred embodiment, two other sets of fixed blocks are symmetrically fixedly connected to one side of the exterior of the fixed frame close to the power transmission gear train, and the other two sets of fixed blocks are rotatably connected to two other sets of top support wheels at one end close to the power transmission gear train.

[0010] As a preferred embodiment, the outside of the power transmission wheel system and the outside of the fixed frame are fixedly connected with a shell, the function of the tension wheel is to make the rubber-coated power wheel close to the side wall of the track, and a card reader is installed inside the base.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are: In the present invention, the motor is directly connected to the reducer, and the output shaft of the reducer is connected to the gear through a tension sleeve. The power is transmitted to the two rubber-coated power wheels on the left through the power transmission gear train. A tension wheel is installed on the right side, and a spring is provided on the bracket to make the three wheels close to the side wall of the track. There are three top support wheels composed of threaded bearings on the top, which are used to hang the robot above the track. The outer ring of the threaded bearing is made of steel and will not deform under heavy load. This solves the problem that the wheels and the track are too tightly fitted under heavy load in traditional top rubber wheel transmission, and the rubber wheels are deformed by pressure, resulting in excessive running resistance and seriously affecting the service life of the wheels. Compared with traditional devices, the operation quality and use efficiency are greatly improved.

[0013] 2. It solves the problem that the traditional top rubber wheel transmission fits the wheel and the track too tightly under heavy load (the rubber wheel is pressed and deformed), resulting in excessive running resistance and seriously affecting the service life of the wheel.

[0014] 3. The mechanism has been improved to be able to be used on a variety of tracks such as tracks made of I-beams, T-steels and galvanized square tubes. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0019] like Figure 1-Figure 4 As shown, the present invention provides a technical solution: a side-mounted rail-type driving mechanism, including a power transmission gear train 3, a motor 1 is fixedly connected to an external side of the power transmission gear train 3, a reducer 2 is installed at the output end of the motor 1, a tensioning sleeve 10 is fixedly connected to the output shaft of the reducer 2, a gear 11 is fixedly connected to the external side of the tensioning sleeve 10, and the gear 11 is rotatably connected to the top of the power transmission gear train 3, and two other groups of gears 11 are rotatably connected to the two sides of the top of the power transmission gear train 3 away from the gear 11, respectively, and transmission gears are respectively arranged between the other two groups of gears 11 and one of the groups of gears 11, and the gears 11 are respectively meshed with the transmission gears, and the outer lower part of the tensioning sleeve 10 inside the other two groups of gears 11 is fixedly connected with a rubber-coated power wheel 4, and the first deep groove ball bearing 8 and the second deep groove ball bearing 9 are respectively fixedly connected to the outer sides of the rubber-coated power wheel 4 and located on the outside of the tensioning sleeve 10.

[0020] In this embodiment, the motor 1 is directly connected to the reducer 2, and the output shaft of the reducer 2 is connected to the gear 11 through the tension sleeve 10. The power is transmitted to the two rubber-coated power wheels 4 on the left through the power transmission gear train 3. A tension wheel 6 is installed on the right side, and there are springs on the bracket to make the three wheels close to the side wall of the track. There are three top support wheels 12 composed of threaded bearings on the top, which are used to hang the robot above the track. The outer ring of the threaded bearing is made of steel and will not deform under heavy load, which solves the problem that the traditional top rubber wheel transmission fits the wheel too tightly with the track under heavy load, and the rubber wheel is pressed and deformed, resulting in excessive running resistance and seriously affecting the service life of the wheel. Example

[0021] like Figure 1-Figure 4As shown, the bottom of the power transmission gear train 3 is fixedly connected to a base, the top of the base is fixedly connected to a fixing frame on the side away from the power transmission gear train 3, and a tensioning wheel 6 matching the rubber-coated power wheel 4 is arranged on the upper part of the interior of the fixing frame. A rotating column is rotatably connected between the base and the fixing frame at the bottom of the power transmission gear train 3, and bottom auxiliary wheels 5 are fixedly connected to the outer sides of the rotating column. A fixed block is fixedly connected to the top of the power transmission gear train 3 and located between the other two groups of gears 11. One end of the outer side of the fixed block is rotatably connected to a top support wheel 12, and the outer side of the fixing frame is symmetrically fixedly connected to the other two groups of fixed blocks on the side close to the power transmission gear train 3. The other two groups of fixed blocks are rotatably connected to the other two groups of top support wheels 12 at one end close to the power transmission gear train 3. The outer side of the power transmission gear train 3 and the outer side of the fixing frame are fixedly connected to a shell 13. The function of the tensioning wheel 6 is to make the rubber-coated power wheel 4 close to the side wall of the track, and a card reader 7 is installed inside the base. In this embodiment, the wheel train frame is composed of two steel wheel train side plates and four support columns. The bottom is a fuselage connecting part made of 5 mm thick sheet metal. The left side with gears is the power part of the drive mechanism. This part is modular and can be installed on a bracket that adapts to different tracks. The position of the auxiliary wheel will vary for different tracks. The right side is a tensioning mechanism, which is used to make the power wheel close to the side wall of the track.

[0022] Working principle: like Figure 1-Figure 4 As shown, the wheel train frame consists of two steel wheel train side plates and four support columns. The bottom is a fuselage connector made of a 5mm thick sheet metal. The left part with a gear is the power part of the drive mechanism. This part is modular and can be installed on a bracket that adapts to different tracks. The position of the auxiliary wheel will vary for different tracks. The right side is a tensioning mechanism, which is used to make the power wheel close to the side wall of the track. The motor 1 is directly connected to the reducer 2. The output shaft of the reducer 2 is connected to the gear 11 through a tensioning sleeve 10. The power is transmitted to the two rubber-coated power wheels 4 on the left through the power transmission wheel train 3. A tensioning wheel 6 is installed on the right side. There are springs on the bracket to make the three wheels close to the side wall of the track. There are three top support wheels 12 composed of threaded bearings on the top, which are used to hang the robot above the track. The outer ring of the threaded bearing is made of steel and will not deform under heavy load. This solves the problem that the wheels of the traditional top rubber wheel transmission fit too tightly with the track under heavy load, the rubber wheels are deformed by pressure, and the running resistance is too large, which seriously affects the service life of the wheels. Compared with traditional devices, the operation quality and use efficiency are greatly improved.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
