As shown in fig. 2, in the present application, the catheter assembly 3 includes a strong catheter end 31 and an interlocking catheter end 32 which are disposed opposite to each other, a catheter shaft 33 between the strong catheter end 31 and the interlocking catheter end 32, and a catheter piece 34 which reciprocally slides along the catheter shaft 33, the catheter shaft 33 being of a bi-directional lead screw structure, the direction of rotation of the catheter end 31 being forced to be opposite to the direction of rotation of the interlocking catheter end 32; the strong guide pipe end 31 and the interlocking guide pipe end 32 can enable the guide pipe end 33 to be in different rotation directions, when the whole is in normal operation, the interlocking guide pipe end 32 runs at the moment, so that the heat exchange pipe 3 moves to the cylinder core of the heat exchange pipe 3 from the position of the pipe storage cylinder 2 through the guide pipe piece 34, wherein the heat exchange pipe 3 is wound at the position of the pipe storage cylinder 2, and after a layer of the heat exchange pipe is firstly paved during winding, a new layer of the heat exchange pipe is continuously wound on the previous layer, so that when the heat exchange pipe 3 is moved out from the position of the pipe storage cylinder 2, the moving point of the heat exchange pipe 3 can reciprocate in the axial direction of the pipe storage cylinder 2, the drawing of the heat exchange pipe 3 layer by layer is realized, and the guide pipe piece 34 can reciprocate along the guide pipe shaft 33, so that when the moving position of the heat exchange pipe 3 is changed, the position of the guide pipe piece 34 can synchronously change, the heat exchange pipe 3 is ensured to be in a flush state between the pipe storage cylinder 2 and the guide pipe piece 34, and bending damage of the heat exchange pipe 3 is avoided.
The interlocking conduit end 32 operates when the heat exchange tube 3 normally moves, when the heat exchange tube 3 fails in guiding, for example, the heat exchange tube 3 is blocked at the conduit member 34, but the heat exchange tube 3 still moves out of the storage tube body 2 under the action of the heat exchanger tube core, accumulation of the heat exchange tube 3 can occur at the conduit member 34, not only can the heat exchange tube 3 bend to affect subsequent use, but also the storage tube body 2 can be blocked when the accumulation is excessive, so that the storage tube body 2 cannot normally rotate, the current of a main power component driving the storage tube body 2 is increased, danger is easy to occur, at this time, the interlocking conduit end 32 is switched into the forced conduit end 31, and because the interlocking conduit end 32 moves the heat exchange tube 3 out of the storage tube body 2, the strong conduit end 31 then rewinds the heat exchange tube 3 to the storage tube body 2, so that the heat exchange tube 3 accumulated at the conduit member 34 can be rewound to the heat exchange tube body, and safety in use is ensured; alternatively, when the worker finds that the heat exchange tube 3 is erroneously welded to the heat exchanger tube core, for example, the welding of the position of the heat exchange tube 3 is wrong, the heat exchange tube 3 is also required to be rewound to the tube storage tube body 2, and then the heat exchange tube 3 is removed again, and at this time, the strong guide tube end 31 can be started to pull the heat exchange tube 3 outside the tube storage tube body 2 back to the tube storage tube body 2.
It can be understood that the first pulling force of the tube body 2 acting on the heat exchange tube 3 in the present application is the force generated when the interlocking tube end 32 operates, i.e. the heat exchange tube 3 is normally wound, and when the forced tube end 31 is started, the strong tube end 31 is used to rewind the heat exchange tube 3 to the tube body 2, so that after the strong tube end 31 is started, the first pulling force is increased, so as to ensure that the piled heat exchange tube 3 can be rewound to the tube body 2.
In the present application, when a fault occurs and needs to be automatically switched from the chained catheter end 32 to the strong catheter end 31, a current sensor can be arranged at the main power component, and when a large current change is detected, the forced calandria end is started to work, wherein the installation of the current sensor and the connection of a circuit in the present application can be referred to the prior art, and the details are not repeated here.
Preferably, the transfer power assembly comprises a hydraulic motor drivingly connected to the forced conduit end 31, and the main power assembly comprises a servo motor drivingly connected to the interlocking conduit end 32; because the interlocking guide tube end 32 is started during normal operation, namely the starting time of the interlocking guide tube end 32 is relatively long, the interlocking guide tube end 32 is in transmission connection with the interlocking guide tube end 32 through the servo motor, the energy-saving effect is good by adopting the servo motor, meanwhile, the whole noise of the servo motor is low, the heating is less, the efficiency is higher, and meanwhile, the operation by adopting the servo motor is also more convenient; the forced conduit end 31 is connected with a hydraulic motor, so that larger force and moment are easy to obtain, the heat exchange tube 3 is conveniently and rapidly guided to the tube storage tube body 2, and meanwhile, the forced conduit end can be rapidly started and stopped, and the impact on current is small.
The strong guide pipe end 31 is provided with a first sprocket wheel which is in transmission connection with the hydraulic motor through a torque limiter, and the interlocking guide pipe end 32 is provided with a second sprocket wheel which is in transmission connection with the servo motor; the hydraulic motor drives the catheter shaft 33 to rotate through the first sprocket, so that the reciprocating movement of the catheter piece 34 at the catheter shaft 33 is realized, and the servo motor drives the catheter shaft 33 to rotate through the second sprocket, so that the reciprocating movement of the catheter piece 34 at the catheter shaft 33 can be realized.
Preferably, the catheter assembly 3 further comprises sliding sleeves disposed on both sides of the catheter shaft 33 to support the catheter shaft 33; by providing the sliding sleeve, the catheter shaft 33 can be more stable after installation.
The foregoing is merely exemplary of the present application and is not intended to limit the present application. Various modifications and variations of the present application will be apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. which come within the spirit and principles of the application are to be included in the scope of the claims of the present application.
