DETAILED DESCRIPTION

[0042] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0043] like Figure 1 to Figure 4 As shown, an inclined transfer lifting device includes a supporting side plate 100 and a lifting platform 200; the supporting side plate 100 is inclinedly provided with a transmission channel; the lifting platform 200 is movably arranged in the transmission channel, and a transmission mechanism is arranged between the lifting platform 200 and the supporting side plate 100; among the supporting side plate 100 and the lifting platform 200, one of them is provided with a supporting guide wheel 1, and the other is provided with a guide wheel groove 4 or a guide rail 2 cooperating with the supporting guide wheel 1; the extension direction of the guide wheel groove 4 or the guide rail 2 is parallel to the extension direction of the transmission channel.

[0044] This embodiment can be used for inspection operations of rail vehicles. Generally speaking, automated inspection operations are completed by inspection robots, and inspection robots are required to conduct safety inspections on the bottom and sides of rail vehicles to find problems and eliminate potential safety hazards in the operation of rail vehicles. Usually, the inspection robot needs to be operated to two height difference positions to carry out inspection operations. The rapid transportation between the bottom and side of the vehicle improves the inspection efficiency and shortens the maintenance time of rail vehicles. These are the technical effects that can be achieved by the application of this embodiment. The above-mentioned two height difference positions generally refer to two locations, the ditch and the ground. There are usually steps or slopes between the ditch and the ground. The slope can be a flat slope or a curved slope. Regardless of whether it is regular or not, this embodiment can achieve efficient and safe transportation.

[0045] Specifically, the support side plate 100 is installed on the side of the trench, so a transmission channel is formed between the two sides of the trench through the support side plate 100. After the lifting platform 200 is assembled to the support side plate 100, the inspection robot can be reciprocated between the trench and the ground when the inspection robot enters the lifting platform 200. In this embodiment, the support side plate 100 is provided with a support guide wheel 1, and the support side plate 100 is provided with a guide rail 2. Therefore, the support side plate 100 can support the lifting platform 200 by using the support guide wheel 1 and the guide rail 2 that are mutually movable and coordinated, and can maintain a high support stability after the inspection robot enters the lifting platform 200.

[0046] In order to better use this embodiment, one of the supporting side plate 100 and the lifting platform 200 is provided with a lateral guide wheel 3 for assisting the movement of the lifting platform 200, and the axis of the lateral guide wheel 3 is perpendicular to the guide wheel groove 4 or the guide rail. Specifically, the supporting side plate 100 is provided with a guide wheel groove 4, and the lifting platform 200 is provided with a lateral guide wheel 3. Therefore, in the process of the lifting platform 200 moving relative to the supporting side plate 100, the lateral guide wheel 3 rotates relative to the guide wheel groove 4 to achieve auxiliary movement of the lifting platform 200, so that the movement of the lifting platform 200 is more stable and smooth.

[0047] like Figure 1 to Figure 3 As shown, in this embodiment, the transmission mechanism includes a creeping gear 5 and a rack 6 that mesh with each other. Among the creeping gear 5 and the rack 6, one is arranged on the supporting side plate 100, and the other is arranged on the lifting platform 200. Further, the creeping gear 5 is arranged on the lifting platform 200, and the rack 6 is arranged on the supporting side plate 100. In this embodiment, a servo motor is used to drive the creeping gear 5 to rotate. Since the creeping gear 5 and the rack 6 are meshed with each other, and the rack 6 is fixedly arranged on the supporting side plate 100, the lifting platform 200 can well meet the motion requirements and ensure a high motion capacity in terms of the action of the servo motor. It can be known that in some other embodiments, the transmission mechanism can be a telescopic cylinder transmission mechanism, a belt transmission mechanism, or a chain transmission mechanism, and the above transmission mechanism can also achieve a better transportation effect.

[0048] like Figure 4 As shown, further, the transmission mechanism also includes a power source 7 and a clutch 8 in transmission connection, and the clutch 8 is in transmission connection with the creeping gear 5. Specifically, the transmission mechanism also includes a reducer 9 and a coupling 10. The power source 7 is a driving motor, and the two ends of the coupling 10 are respectively connected to the reducer 9 and the clutch 8. Therefore, after the power source 7 outputs the power, the power is transmitted to the creeping gear 5 through the reducer 9, the coupling 10, and the clutch 8, thereby realizing the oblique movement of the lifting platform 200 relative to the supporting side plate 100. Therefore, when the clutch 8 is powered on, the gear disc of the clutch 8 is separated to allow the lifting platform 200 to move in the transmission channel, and when the clutch 8 is powered off, the gear disc of the clutch 8 is engaged to prevent the lifting platform 200 from falling.

[0049] like Figure 3As shown, in this embodiment, it also includes a front sensor 11, a middle sensor 12 and a rear sensor 13 arranged on the lifting platform 200. Obviously, the front sensor 11 is located at the front end of the lifting platform 200, the middle sensor 12 is located in the middle of the lifting platform 200, and the rear sensor 13 is located at the rear end of the lifting platform 200. The front sensor 11 and the rear sensor 13 are used to detect whether the inspection robot has completely left the lifting platform 200, or whether an external object blocks the travel path, while the middle sensor 12 is used to detect whether the inspection robot stops in the middle position of the lifting platform 200. When the inspection robot is in place, the lifting platform 200 can be driven to move, thereby improving the safety of transportation. Further, it also includes a magnet 14 arranged in the middle of the lifting platform 200, which is used to sense the magnetic sensor on the object to be transported. Similar to the middle sensor 12, the induction of the magnet 14 and the magnetic sensor is used to detect whether the inspection robot stops in the middle position of the lifting platform 200 to ensure that the inspection robot is in place on the lifting platform 200. In this embodiment, the front-end sensor 11, the middle-end sensor 12 and the rear-end sensor 13 may be photoelectric sensors, ultrasonic sensors and the like.

[0050] In this embodiment, both ends of the lifting platform 200 are provided with safety touch edges 15. The safety touch edges 15 can be configured by flexible parts, such as cotton strips, damping springs, etc., so as to provide collision buffering when there is an oblique movement of the lifting platform 200 and there is an obstruction by external objects. Furthermore, the safety touch edges 15 are provided with touch switches. The touch switches are contact switches, and their transmission mechanisms are connected in communication, so as to meet the requirement of achieving emergency stop when the lifting platform 200 collides.

[0051] In order to better use this embodiment, it also includes a safety baffle 16, which can be movably arranged on the lifting platform 200, and is used to limit the movement of the objects to be transported on the lifting platform 200. Further, the safety baffle 16 is rotatably arranged on the lifting platform 200, and can be switched between the blocking position and the avoidance position; the lifting platform 200 is provided with an avoidance hole for the movement of the safety baffle 16. The safety baffle 16 is linked with the front sensor 11, the middle sensor 12, and the rear sensor 13, and can be linked with the magnet and the magnetic sensor, that is, when the inspection robot moves to the right position on the lifting platform 200, the safety baffle 16 switches from the avoidance position to the blocking position. In other words, after confirming that the position of the inspection robot is correct, the safety baffle 16 of the lifting platform 200 swings to a vertical position to protect the inspection robot by mechanical limiting during the movement.

[0052] Therefore, this embodiment can achieve the operation in the following manner.

[0053] 1. After the inspection robot completes the inspection of the bottom of the rail vehicle in the trench, the lifting device receives the completion signal from the inspection robot and moves the lifting platform 200 to the boarding position in the trench.

[0054] 2. When the inspection robot enters the lifting platform 200, the inspection robot is detected by the rear-end sensor 13. At the same time, the sensor is used to detect whether there are any objects blocking the outside of the lifting platform 200 to prevent collision until the inspection robot drives to the middle of the lifting platform 200.

[0055] 3. The front position and the rear position of the inspection robot are detected by the mid-end sensor 12 of the lifting platform 200. At the same time, the magnetic sensor configured by the inspection robot senses the magnet 14 on the lifting platform 200 to confirm the parking position again.

[0056] In this step, if the front sensor 11, the middle sensor 12, and the rear sensor 13 all detect the chassis of the inspection robot, it is considered that the inspection robot is in the middle position. If one of the front sensor 11 and the rear sensor 13 senses the chassis and the other does not sense the chassis, it is considered that the inspection robot is not in the middle, and the lifting platform 200 cannot be lifted or lowered.

[0057] 4. After confirming that the inspection robot is in the correct position, the safety baffle 16 swings to the vertical position.

[0058] 5. After completing the above steps, the lifting platform 200 moves to transfer the inspection robot from the trench to the ground. When it rises to the ground level, the clutch 8 is powered off and engaged.

[0059] 6. After the inspection robot receives the signal that the lifting platform 200 is in place, the inspection robot drives out of the lifting platform 200. The lifting platform 200 can move only after the sensor 11 at the front end of the lifting platform 200 completely stops sensing objects. The sensor also detects whether there are any objects blocking the outside of the lifting platform 200 to prevent collision.

[0060] 7. Use inspection robots to perform inspection tasks on the sides of rail vehicles.

[0061] It can be known that the above steps are to detect the bottom of the vehicle first and then the side of the vehicle. In different detection methods, the order of detecting positions can be reversed. The specific steps can be referred to the above process and will not be repeated here.

[0062] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention. The protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
