[0018] like Figure 1 As shown, in a preferred embodiment, the motor mounting structure of a pipeline robot according to this utility model includes a motor base 1 and a motor mounting seat 2, which are fixedly connected. The motor base 1 is simultaneously connected to a first motor 4 and a second motor 5. The non-output ends of the first motor 4 and the second motor 5 are connected to the motor base 1, and the output ends of the first motor 4 and the second motor 5 are connected to the motor mounting seat 2. Thus, the motor base 1 and the motor mounting seat 2 form a single fixed structural component. Using a single structural component to assemble the two motors (first motor 4 and second motor 5) results in a more compact structure, smaller overall size, and reduced space occupation.

[0019] like Figure 2As shown, in a preferred embodiment, a first bearing 8 and a second bearing 9 arranged side-by-side are installed in the motor mounting base 2. The first bearing 8 and the second bearing 9 are respectively connected to a first gear 11 and a second gear 12. The first gear 11 and the second gear 12 are respectively connected to the output shafts of the first motor 4 and the second motor 5, thereby driving the first gear 11 and the second gear 12. The first gear 11 and the second gear 12 are connected to the operating components of the pipeline robot. This invention does not involve other components of the pipeline robot, therefore they are not described.

[0020] In a preferred embodiment, a shock-absorbing block 6, which is fixedly connected to the motor mounting base 2, is connected between the first bearing 8 and the second bearing 9. During motor assembly, the first motor 4 and the second motor 5 do not contact each other, nor do the first bearing 8 and the second bearing 9. The vibrations generated by the two motors are transmitted only from outside the motor mounting base 2. With the shock-absorbing block 6 installed on the motor mounting base 2, some of the vibrations generated by the two motors can be buffered and attenuated within the motor mounting base 2, reducing the adverse effects of vibration between the two motors, improving the structural stability of the dual-motor assembly, and ensuring the service life of the two motors in the pipeline robot.

[0021] A top cover 3 is connected to the upper part of the motor mounting base 2. The top cover 3 has several first mounting holes 301 and several second mounting holes 302. The top cover 3 is used to cover the motor mounting base 2. The first mounting holes 301 are connected to the shock absorber 6, which fixes the shock absorber 6 to the motor mounting base 2 and makes the two sides of the shock absorber 6 abut against the first bearing 8 and the second bearing 9, respectively. The shock absorber 6 extends along the length of the motor mounting base 2 and abuts against the first motor 4 and the second motor 5. At the same time, the outer periphery of the first gear 11 and the second gear 12 is fitted with a shock-absorbing ring 10 that abuts against the shock absorber 6 and the motor mounting base 2, which can further buffer and dampen the vibration generated by the two motors inside the motor mounting base 2.

[0022] like Figure 3 As shown, in a preferred embodiment, the damping block 6 extends towards the motor base 1 and has a damping plate 7 that abuts against the first motor 4 and the second motor 5. The damping plate 7 dampens the vibration of the two motors outside the motor mounting base 2, and a sealed buffer cavity 13 is provided between the damping block 6 and the damping plate 7. The damping block 6 and the damping plate 7 can be integrally formed. In this case, when the damping block 6 and the damping plate 7 are vibrated in both directions, the buffer cavity 13 can further buffer the vibration and reduce the impact of the vibration on the two motors. It is known that the damping block 6 and the damping plate 7 are made of rubber material, but they can also be made of damping materials such as polyurethane or thermoplastic elastomers.

[0023] The preferred specific embodiments and examples of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments and examples, and various changes or equivalent replacements can be made within the knowledge range possessed by the person skilled in the art without departing from the concept of the utility model, therefore, the utility model is not limited by the specific embodiments disclosed herein, and all the embodiments falling within the scope of the claims of the application belong to the range protected by the utility model.
