[0024] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1, refer to Figure 1-Figure 7The trolley 1 is provided with a guide rail 2 on both sides of the rail trolley 1, and a driving motor 31 is installed inside the rail trolley 1, and the wheels 3 are fixedly connected to the output end of the driving motor 31. The rail trolley 1 is slidably arranged on the guide rail 2. The driving motor 31 can drive the rail trolley 1 to move on the guide rail 2. The left end side wall of the rail trolley 1 is provided with a three-color signal light 4, which is used to prompt different states of the vehicle. When the vehicle is running, the green light is on, when the vehicle stops, the red light is on, and when the vehicle fails, the yellow light is on.

[0026] Furthermore, an opening cover assembly is provided at the lower right end of the rail trolley 1, and the opening cover assembly includes an adjusting motor 7, a first gear 71 and a second gear 72. The adjusting motor 7 is fixedly mounted on the right bottom of the rail trolley 1, and the output end of the adjusting motor 7 is fixedly connected to the first gear 71, and the first gear 71 is meshed with the second gear 72. The connecting shaft of the second gear 72 is rotatably connected to the bottom of the rail trolley 1, and the bottom of the second gear 72 is fixedly connected to the connecting frame 61 and the mounting plate 81. The bottom side of the connecting frame 61 is fixedly mounted with an opening rod 6. When the adjusting motor 7 is started, the first gear 71 starts to rotate, and because the first gear 71 is engaged with the second gear 72, the connecting shaft of the second gear 72 is rotatably connected to the bottom of the rail trolley 1. The gear 71 is meshed with the second gear 72, and at this time the second gear 72 starts to drive the connecting frame 61 and the mounting plate 81 to rotate. At this time, the opening rod 6 will rotate with the connecting frame 61 to match the top cover 11 in different positions (because the positions of different top covers 11 are different, the opening rod 6 needs to be rotated to different angles at different positions to lift the top cover 11 through the pull rod 12). Buffer assemblies are provided on both sides of the rail trolley 1 to provide buffering for the rail trolley 1. Taking into account that there may be unevenness or vibration on the top of the coke oven 10, the stability of the trolley under complex working conditions can be improved by setting the buffer assembly.

[0027] It should be noted that: the angle between the connecting frame 61 and the mounting plate 81 is 90 degrees, and a temperature measuring mechanism 8 is installed at the rear end of the connecting frame 61. The connecting frame 61 and the mounting plate 81 rotate synchronously, which enables the temperature measuring mechanism 8 to accurately locate the temperature measuring point of the coke oven 10 as the opening rod 6 rotates. When the opening rod 6 pulls up the top cover 11, the temperature measuring mechanism 8 can measure the temperature inside the coke oven 10 in real time. The temperature measuring mechanism 8 is a thermocouple. As a special electronic instrument, the main function of the thermocouple is to measure and monitor the temperature of a substance. It uses the resistance principle formed by the change of resistance value due to temperature to measure the temperature quickly and accurately. In the scenario of measuring the temperature of the coke oven 10, the thermocouple can directly measure the temperature inside the coke oven 10, providing key temperature data for production.

[0028] Reference Figure 3-Figure 6 The buffer assembly includes a mounting frame 5 fixedly arranged on both sides of the rail trolley 1. The mounting frame 5 is arranged in an L shape. The upper side of the bottom plate of the mounting frame 5 is fixedly connected to a buffer spring 92. The upper end of the buffer spring 92 is fixedly connected to a connecting seat 9. A ball 91 is rotatably arranged in the upper end of the connecting seat 9.

[0029] It should be noted that the bottom of the mounting frame 5 is located on the lower side of the guide rail 2, and the upper end of the ball 91 is in contact with the bottom of the guide rail 2. Through the setting of the mounting frame 5, the rail trolley 1 can be limited to prevent it from leaving the guide rail 2. In the initial state, there is a gap between the bottom of the connecting seat 9 and the upper side of the bottom plate of the mounting frame 5. Through the setting of the ball 91 and the buffer spring 92, the vibration of the rail trolley 1 during operation can be effectively reduced, thereby improving the operating stability of the rail trolley 1.

[0030] In the second embodiment, the opening rod 6 is a trapezoidal rod inclined downward, and the opening rod 6 is detachable for easy replacement. The opening rod 6 can also be a U-shaped rod or other lid opening device with a hook, which can also achieve the same lid opening effect.

[0031] The working principle of the trolley for walking and opening the cover on the top of the coke oven is as follows: the rail trolley 1 slides on the guide rail 2 on the top of the coke oven 10 through the wheels 3, and the driving motor 31 provides power for the wheels 3 so that it can move along the guide rail 2.

[0032] Opening function: When the rail trolley 1 moves to the position of the coke oven 10 where the cover needs to be opened, the adjusting motor 7 is started, and the adjusting motor 7 drives the first gear 71 to rotate. The first gear 71 engages with the second gear 72, thereby driving the second gear 72 and its connected connecting frame 61 and mounting plate 81 to rotate, and the opening rod 6 on the bottom side of the connecting frame 61 rotates to a suitable position to match the pull rod 12 of the top cover 11, so that the top cover 11 can be opened. Since the furnace cover is usually very heavy, the traditional opening method requires the cooperation of multiple people and requires operation close to the furnace cover. This method has the risk of being hit by the furnace cover or injured by heat radiation from the high-temperature furnace. Through this device, the opening rod 6 can be used for operation, and the operator can maintain a certain safety distance, avoiding and reducing the risks caused by improper position, such as being hit, scalded, etc.

[0033] Temperature measurement function: When the opening rod 6 successfully pulls up the top cover 11, the temperature measuring mechanism 8 (such as a thermocouple) can measure the temperature inside the coke oven 10 in real time.

[0034] Buffering function: During the movement of the rail trolley 1, it may be affected by factors such as the unevenness or vibration of the top of the coke oven 10. The buffer assembly absorbs and reduces these vibrations through the setting of the buffer spring 92 and the ball 91, thereby improving the operation stability of the trolley. At the same time, the mounting frame 5 can also limit the rail trolley 1 to prevent it from leaving the guide rail 2.

[0035] Through the cooperation of the driving motor 31 and the regulating motor 7, the automatic opening of the coke oven 10 cover is realized. In addition to the cover opening function, the trolley is also equipped with a temperature measuring mechanism 8, which can measure the temperature inside the coke oven 10 in real time, providing more useful information for production and greatly improving work efficiency. The rail trolley 1 can move freely on the guide rail 2, which is convenient for opening the cover of the coke oven 10 at different positions; the opening rod 6 in the cover opening assembly can be rotated to match the top cover 11 at different positions, which enhances the flexibility of the trolley. The detachable design of the opening rod 6 facilitates replacement and maintenance, and improves the adaptability of the trolley; the setting of the buffer assembly effectively reduces the vibration of the trolley under complex working conditions and improves the operating stability.
