This design is conducive to triggering the trigger button 510 to make the speaker 59 sound an alarm.

[0030] The top of the base 2 is fixedly connected to a limiting rod 511, and a limiting groove 512 is provided inside the limiting rod 511. The inside of the limiting groove 512 is slidably connected to a collection box 513.

This design is conducive to resetting the collection box 513 through the spring 514.

[0031] The trigger button 510 is located on the displacement track of the collection box 513. The side of the collection box 513 is elastically connected to the top of the base 2 through a spring 514. This design is conducive to collecting the leaked coal tar through the collection box 513 to reach a certain weight, so that the collection box 513 touches the trigger button 510, causing the speaker 59 to sound an alarm.

[0032] A heating device 6 is provided on the top of the base 2, and the heating device 6 includes a fan blade frame 61. The bottom of the fan blade frame 61 is fixedly connected to the top of the base 2, and the internal rotation of the fan blade frame 61 is connected to the rotating shaft 62.

[0034] The number of blades 66 is set to be several, and they are arranged in a circumferential array on the circumferential surface of the rotating shaft 62. This design is conducive to the use of multiple blades 66 to achieve better heating effects.

[0035] A specific application of this embodiment is: in the process of punching, in order to prevent the connection between the pump body 3 and the straight pipe 4 from being unstable and causing coal tar to leak, it is necessary to fix it. First, start the motor 51. When the motor 51 is started, the bidirectional threaded rod 53 on the output shaft of the motor 51 rotates clockwise. When the bidirectional threaded rod 53 rotates clockwise, the threaded sleeve 55 on the circumferential surface of the bidirectional threaded rod 53 moves inward horizontally. When the threaded sleeve 55 moves inward horizontally, the fixing plate 56 on the threaded sleeve 55 fixes the connection between the pump body 3 and the straight pipe 4. When the bidirectional threaded rod 53 rotates counterclockwise, the threaded sleeve 55 on the circumferential surface of the bidirectional threaded rod 53 moves horizontally outward. When the threaded sleeve 55 moves horizontally outward, the fixing plate 56 on the threaded sleeve 55 loosens the connection between the pump body 3 and the straight pipe 4. When coal tar leaks out, it falls into the collection box 513 below the connection. When the coal tar in the collection box 513 reaches a certain weight, the collection box 513 touches the trigger button 510. When the trigger button 510 is touched, the sound 59 sounds an alarm to remind the staff of coal tar leakage.

[0036] During production, because coal tar is relatively viscous at room temperature, it is difficult to flow, so the coal tar needs to be heated. First, the baffle 611 is opened, and then the motor 51 is started. When the motor 51 is started, the bidirectional threaded rod 53 on the output shaft of the motor 51 rotates clockwise. When the bidirectional threaded rod 53 rotates clockwise, the rotating shaft 62 driven by the belt 65 and the bidirectional threaded rod 53 rotates clockwise. When the rotating shaft 62 rotates clockwise, the blades 66 on the rotating shaft 62 blow air to the vent 68. When the bidirectional threaded rod 53 rotates counterclockwise, the rotating shaft 62 driven by the belt 65 and the bidirectional threaded rod 53 rotates counterclockwise. When the rotating shaft 62 rotates counterclockwise, the blades 66 on the rotating shaft 62 cannot blow air to the vent 68.
