DETAILED DESCRIPTION

[0019] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] Embodiment 1:

[0021] like Figure 1~Figure 3 As shown, the utility model provides a technical solution, a CCTV robot mobile platform, including a lifting module and a landing platform 19; the lifting module includes a lower annular ring 1, an upper annular ring 2, a transmission ring 3, a rotating wheel 4 and a driving device 5, a support column 6 is fixedly connected between the lower annular ring 1 and the upper annular ring 2, the transmission ring 3 is rotatably installed between the upper annular ring 2 and the lower annular ring 1, the cross-section of the transmission ring 3 is an inverted prism shape, and transmission teeth are provided on both sides of the transmission ring 3, and the rotating wheel 4 is rotatably installed on the upper annular ring 2. Between the upper annular ring 2 and the lower annular ring 1, the wheels 4 are arranged in an annular array, and the wheels 4 are all wound with ropes 8, and the ends of the ropes 8 are fixed on the landing platform 19. The rotating shaft of the wheel 4 is fixedly connected with a first bevel gear 9 that cooperates with the transmission ring 3 for transmission. The driving device 5 is fixedly installed on the upper annular ring 2, and the rotating shaft of the driving device 5 is fixedly connected with a second bevel gear 10 that cooperates with the transmission ring 3 for transmission. The landing platform 19 is provided with a telescopic trestle 11, and the trestle 11 is used for the passage of the CCTV robot.

[0022] The working principle is: first, place the device to align with the wellhead, with the trestle 11 extending in the direction of the pipeline flow, and then place the CCTV robot on the landing platform 19. Then operate the driving device 5, which can select a servo motor, and first transmit the driving force of the servo motor to the transmission ring 3. When the transmission ring 3 rotates, the transmission teeth on the transmission ring 3 synchronously drive all the wheels 4 to rotate together, and release the suspension rope 8 on the wheel 4. After releasing the suspension rope 8, the landing platform 19 descends. When the landing platform 19 descends to a suitable position at the wellhead, the trestle 11 is extended into the pipeline until the trestle 11 overlaps the inner wall of the pipeline, and the CCTV trolley can enter the pipeline through the trestle 11 for detection. In this way, the movement from the inspection well to the pipeline with a height difference is completed, fundamentally avoiding the limited space operation risk brought by personnel going down to the well to place the CCTV robot, greatly improving safety, and at the same time, compared with the conventional rope-hook CCTV robot, it reduces the preparation work links such as continuous ventilation and gas detection in the pipeline, with high efficiency, short time and simple operation.

[0023] In this embodiment, if Figure 3~Figure 5 As shown, the landing platform 19 is provided with two layers of chute arranged in parallel, the trestle 11 is slidably connected to the upper chute, and the lower chute is slidably connected to the counterweight 12. The landing platform 19 is also provided with a power device 13, which drives the trestle 11 and the counterweight 12 to move in the opposite direction at the same time. A robot is placed on the trestle 11, and when the power device 13 drives the trestle 11 to extend, the counterweight 12 moves in the opposite direction to balance the landing platform 19, thereby ensuring the stability of the entire landing platform 19 and facilitating the smooth movement of the robot.

[0024] In this embodiment, if Figure 4 As shown, the power device 13 is a motor, and a gear plate 14 arranged between the trestle 11 and the counterweight 12 is fixedly connected to the rotating shaft of the motor, and a toothed belt that cooperates with the gear plate 14 is provided on the side adjacent to the trestle 11 and the counterweight 12. The rotation of the motor drives the gear plate 14 to rotate, and the rotation of the gear plate 14 drives the trestle 11 and the counterweight 12 that cooperate with the gear plate 14 to move in the opposite direction at the same time, so as to balance the landing platform 19, which is convenient to use.

[0025] Embodiment 2:

[0026] On the basis of this embodiment 1, as shown in Figure 5, the power device 13 is an electric bidirectional cylinder, the middle part of which is fixed on the landing platform 19, and the two ends of the telescopic shaft are respectively fixed on the trestle 11 and the counterweight 12. The electric bidirectional cylinder is used to replace the motor, so that the bidirectional cylinder is driven, and the movement speed of the counterweight 12 can be adjusted according to the situation, which is more convenient to adjust the balance of the entire landing platform 19.

[0027] Embodiment 3:

[0028] On the basis of Example 1, Figure 2 As shown, an L-shaped support plate 15 is fixedly connected to the upper annular ring 2, and a roller 16 is fixedly installed on the support plate 15. The roller 16 contacts the bottom of the transmission ring 3, and an annular convex ring 17 is fixedly connected to the top of the transmission ring 3. An annular groove 18 that slidably cooperates with the convex ring 17 is fixedly connected to the bottom surface of the upper annular ring 2. The annular groove 18 is used to slide the transmission ring 3, and the roller 16 is used to support the transmission ring 3, so that the transmission ring 3 is more stable when rotating, which is convenient for driving all the wheels 4 to rotate at the same time to balance the lifting landing platform 19.

[0029] Embodiment 4:

[0030] On the basis of Example 1, Figure 2As shown, a pulley 7 corresponding to the rotating wheel 4 is fixedly mounted on the support column 6, and the suspension rope 8 is passed through the pulley 7. It is convenient for the suspension rope 8 to synchronously lift the landing platform 19.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
