By the arrangement mode, the control circuit can realize the control of two modes of wireless remote control and wire control of the tube bundle pumping and installing machine. When wireless control is carried out, the control signal can be transmitted to the latch module through the main control chip by the wireless module, and then is transmitted to the unique corresponding coding relay by the latch module to be processed and then output. When the wire control is carried out, the control signal can be transmitted to the latch module by the wire control module through the main control chip, and then is transmitted to the unique corresponding coding relay by the latch module to be processed and then output. The address module is provided with 8 dial switches, and the switching between remote control and line control modes can be realized through the on-off of a pin in one bit of the switch. The arrangement mode enables the control mode of the tube bundle pumping and installing machine to be more diversified and the operation safety to be higher.

Besides the control modes of wire control and remote control, power switches of action execution units such as a power mechanism, a motor and the like can be led to the outside of the tube bundle drawing and installing machine through electric wires, and the tube bundle drawing and installing machine can be directly and manually controlled through a mode that field personnel manually control the on-off of a power supply. Therefore, the tube bundle pumping and installing machine can realize three control modes, namely manual control, line control and remote control, greatly enriches the control modes of tube bundle pumping and installing, and improves the safety of the tube bundle pumping and installing operation process.

When the device is used, when the tube bundle needs to be pulled out of the heat exchanger shell, the tube bundle pulling and installing machine is hoisted to the position close to the flange of the heat exchanger shell, the flange of the heat exchanger shell is clamped through the clamping feet 4, and then the pre-tensioning section of the tube bundle is pulled out through the steel cable. Then, the tube sheet segments of the tube bundle are clamped and clamped to the clamping portions of the panel hanging device 10. If the position is not proper, the lifting hanging plate 1003 can be adjusted so as to facilitate the smooth extraction of the tube bundle. The power output by the power mechanism 9 is that the main crane 2 pulls the tube bundle to separate from the shell. During the pulling process, the trolley 5 having an arcuate top surface may be used to support the suspended section of the tube bundle.

When the tube bundle needs to be pushed back into the tube bundle shell, the action of the hydraulic motor 63 can be controlled, so that the push rod 65 can be turned over by 180 degrees, the rear part of the main travelling crane 2 is turned over to the front part, and the main travelling crane 2 can move in the opposite direction to push the tube bundle to enter the tube bundle shell through the pushing device 6. The time for turning the push rod of the push rod device 6 can be within 30 seconds, and compared with the traditional method that the push rod device is stretched through a lead screw or a screw rod, the time is at least shortened by 90%, and the working efficiency can be greatly improved.

Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the invention.
