The heat exchange tube cleaning apparatus as recited in claim 1, wherein the clamping mechanism comprises: the upper clamping arm and the lower clamping arm are arranged below the conveying mechanism, and clamping blocks for clamping the heat exchange tube are arranged on the upper clamping arm and the lower clamping arm; the clamping device comprises an upper clamping cylinder for driving the upper clamping arm to move downwards and a lower clamping cylinder for driving the lower clamping arm to move upwards.
8. The heat exchange tube cleaning apparatus as recited in claim 1, further comprising: and a feeding frame for placing the heat exchange tubes to be detected, and conveying the heat exchange tubes in the feeding frame to the feeding mechanism of the conveying mechanism.
9. The heat exchange tube cleaning apparatus as recited in claim 8, wherein the feed mechanism comprises:
the top surface of the feeding table is obliquely arranged;
the jacking component is used for jacking the feeding frame so that the inclined bottom surface of the feeding frame can be connected with the top surface of the feeding table;
the material limiting handle is arranged on the feeding platform, can extend out of the top surface of the feeding platform or retract into the feeding platform, and divides the top surface of the feeding platform into a pre-feeding area and a to-be-fed area when extending out of the feeding platform;
the material limiting baffle is suspended above the material waiting area, and a material passing gap is formed between the material limiting baffle and the top surface of the feeding table;
the material blocking block is arranged on the feeding table and used for blocking the heat exchange tube of the material passing gap, and the material blocking block and an outlet of the material passing gap form a material ejecting gap at intervals;
the material blocking plate is suspended above the material blocking block, an inclined material passing channel is formed between the material blocking plate and the material blocking block, and the outlet side of the material passing channel is communicated with the conveying mechanism;
and the material ejecting component is arranged below the material loading platform and used for ejecting the heat exchange tubes positioned in the material ejecting gaps to enter the material passing channel.
10. The heat exchange tube cleaning apparatus of claim 9, wherein the pre-load zone houses one of the heat exchange tubes, and the flash gap houses a single row of the heat exchange tubes.
