Description

Technical Field

[0001] The utility model relates to the field of crane pipe loading for automobiles and train tank trucks, and in particular to a full-automatic vertical pipe stroke detection and collision detection device for the crane pipe. Background Art

[0002] With the booming petrochemical industry, the volume of pipe cranes loaded and unloaded at chemical bases continues to grow, increasing the workload of operators. Consequently, the demand for fully automated pipe crane alignment technology is becoming increasingly urgent and has become a mainstream trend in the industry. However, the greatest challenge currently facing fully automated pipe crane alignment technology is ensuring that the pipe crane accurately locates the tank opening.

[0003] If the automatic positioning crane is inaccurately positioned when searching for the tank opening, the drop pipe will not be able to be inserted smoothly into the tank opening, potentially causing it to collide with the edge of the tank opening during descent. Furthermore, if the tank opening height is measured incorrectly, the drop pipe may not reach the intended depth during descent, leading to a series of problems. For example, if the drop pipe is lowered too deep, the outer arm may collide with the tank opening, while if it is lowered too shallow, the chemical medium may overflow from the tank opening during loading, contaminating the tank truck's exterior.

[0004] This device was developed to address this technical challenge. Its core function is to resolve the problem of loading failures caused by inaccurate positioning of the tank opening during the drop pipe's descent. This device provides feedback on the drop pipe's incorrect position and height, ensuring accurate and stable insertion into the tank opening. This effectively improves loading efficiency, reduces operational risks, and provides a strong guarantee for safe production in the petrochemical industry. Utility Model Content

[0005] The purpose of the utility model is to provide a fully automatic crane pipe vertical pipe stroke detection and collision detection device, which has the characteristics of ensuring that the vertical pipe can be accurately dropped into the tank mouth, thereby successfully completing the loading operation.

[0008] The tank mouth baffle assembly includes a tank mouth guide rod and a tank mouth return spring. The top of the tank mouth guide rod passes through the connecting flange. One end of the tank mouth return spring is connected to the connecting flange and the other end is connected to the tank mouth guide rod. The bottom of the tank mouth guide rod is connected to the tank mouth guide cylinder.

[0012] Preferably, the probe detection assembly includes a tank mouth detection probe and a bottom detection probe. The tank mouth detection joint and the bottom detection joint are respectively facing the tank mouth guide rod and the bottom guide rod.

[0024] The present invention will be described in further detail below with reference to the accompanying drawings.

[0025] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0026] Example:

[0027] like Figures 1-9 As shown, the device mainly includes a welding vertical pipe 1, a probe detection component 2, a tank mouth baffle component 5, and a bottoming component 6.

[0028] The welded vertical pipe 1 comprises a rotary joint flange 11, an elbow 12, and a connecting straight pipe 14 which are connected in sequence. A connecting flange 13 is provided on the connecting straight pipe 14.

[0029] The tank mouth baffle assembly 5 comprises two vertically arranged tank mouth guide rods 53, the tops of which extend through the connecting flange 13. A tank mouth spring stop 52 is connected to the rods 53. A tank mouth return spring 51 is sleeved between the portion of the tank mouth guide rods 53 between the connecting flange 13 and the tank mouth spring stop 52. One end of the tank mouth return spring 51 is connected to the connecting flange 13, and the other end is connected to the tank mouth spring stop 52. A tank mouth guide cylinder 56 is connected to the bottom of the two tank mouth guide rods 53. A triangular tank mouth stop plate 57 is attached to each side of the tank mouth guide cylinder 56.

[0030] The bottoming assembly 6 includes two vertically arranged bottoming guide rods 63, the tops of which pass through the connecting flange 13. A bottoming spring stop 62 is connected to the shafts of the bottoming guide rods 63. A bottoming return spring 61 is sleeved on the portion of the bottoming guide rods 63 between the connecting flange 13 and the bottoming spring stop 62. One end of the bottoming return spring 61 is connected to the connecting flange 13, and the other end is connected to the bottoming spring stop 62. A bottoming detection cylinder 67 is connected to the bottoms of the two bottoming guide rods 63.

[0031] The probe detection assembly 2 includes a probe connecting plate 24, a tank opening detection probe 22, and a bottom detection probe 23. The probe connecting plate 24 is L-shaped and fixedly connected to the connecting flange 13. The tank opening detection probe 22 and the bottom detection probe 23 are each horizontally connected to the probe connecting plate 24 and face the direction of the tank opening guide rods 53 and the bottom detection guide rods 63.

[0032] Working principle:

[0033] Bottom detection feedback process: Figure 6 、 7 As shown, after the crane finds the tank opening through the tank opening detection device, it controls the welding drop pipe 1 to move above the tank opening. At this time, the welding drop pipe 1 is lowered. When the welding drop pipe 1 deviates from the tank opening, the bottom detection cylinder 67 first contacts the tank opening. At this time, the welding drop pipe 1 continues to descend, driving the bottom detection cylinder 67 to move relatively upward. The bottom detection cylinder 67 drives the bottom guide rod 63 to move upward. At this time, the bottom guide rod 63 moves to the bottom contact state, the bottom return spring 61 is compressed, and the upper end of the bottom guide rod 63 rises, causing the bottom detection probe 23 to receive a signal, which is fed back to the system to control the welding drop pipe 1 to stop descending and rise. At this time, the bottom return spring 61 extends, driving the bottom spring limit block 62 and the bottom guide rod 63 to move downward and reset. Then the tank opening is found again until the welding drop pipe 1 can be placed in the tank opening.

[0034] Tank mouth detection feedback process: Figure 8 、 9 As shown, after the crane pipe finds the tank mouth through the tank mouth detection device, it controls the welding vertical pipe 1 to move above the tank mouth, and at this time the welding vertical pipe 1 is lowered, and the welding vertical pipe 1 is normally inserted into the tank mouth. At this time, the welding vertical pipe 1 continues to descend until the tank mouth limit plate 57 contacts the tank mouth and continues to descend for a distance. At this time, the tank mouth limit plate 57 drives the tank mouth guide cylinder 56 to move upward, and the tank mouth guide cylinder 56 drives the tank mouth guide rod 53 to move upward. At this time, the tank mouth guide rod 53 moves to the tank mouth contact state, the tank mouth return spring 51 is compressed, and the upper end of the tank mouth guide rod 53 rises, so that the tank mouth detection probe 22 contacts the signal, and the signal is fed back to the system to control the welding vertical pipe 1 to stop descending. At this time, the vehicle can be loaded normally. After the loading is completed, the welding vertical pipe 1 is lifted, and the tank mouth return spring 51 is extended to drive the tank mouth spring limit block 52 and the tank mouth guide rod 53 to move downward and reset, completing the entire loading process.
