In addition, the heating channels of the heaters extend along the second direction, so that the respective heating channels of the heaters distributed along the first direction can be matched with an oil pipe processed by a production line, and a heating effect is provided for the oil pipe. Wherein, heater auto-change over device includes base, mount pad 2, brace table and elevating system.

The base is the foundation structure in the heater switching device, and the base can provide the installation foundation effect for other structures, makes mount pad 2, elevating system and brace table all can directly or indirectly install on the base. Therefore, the base can be made of materials with relatively high structural strength, such as metal, and the like, so that the base is guaranteed to have good structural stability. The structure and shape of the base can be determined according to actual requirements, for example, the base can be a plate-shaped structural member, or the base can be a frame-type structure, which is not limited herein; accordingly, the size of the base can be determined according to the number of heaters required to be carried by the heater switching device.

Similarly, in order to ensure that the mounting base 2 and the supporting platform have reliable supporting capability, the mounting base 2 and the supporting platform may also be formed by using a material such as metal, and the size of the two may also be determined according to actual situations. Mount pad 2 can be frame column structure to reduce the whole weight of mount pad 2, promote the motion performance of mount pad 2, and reduce the drive degree of difficulty of mount pad 2. The support platform can be a plate-shaped structural member, so that the support platform has good bearing capacity, the heaters can be stably supported on the support platform, and a heating effect is provided for the oil pipe.

In order to ensure the capability of switching the position of the heater, the mounting seat 2 is movably matched with the base in the first direction, so that one of the heaters arranged in the first direction corresponding to the position of the production line can be changed under the condition that the mounting seat 2 moves relative to the base. Specifically, the mounting base 2 and the base may form a sliding fit relationship therebetween, for example, the two may be connected to each other through a sliding block and a sliding rail, so that the mounting base 2 and the base can form a stable movable fit relationship in the first direction; or, the base and the mounting base 2 may be combined through a shaft hole structure in the first direction to form a sliding fit relationship, which may also ensure that the mounting base 2 and the base are movably fitted in the first direction.

Simultaneously, the supporting table is still installed in mount pad 2 through elevating system, and elevating system can drive supporting table and mount pad 2 relative motion in the third direction, changes the interval of supporting table and mount pad 2 (or base) in the third direction to make the supporting table drive each heater and descend, in order to dodge and produce the line, correspondingly, the supporting table also can drive each heater and lift, and make required heater correspond with producing the line, guarantee to produce the oil pipe of line production department and can be sent into the heating channel of this heater in by the heating.

Specifically, the lifting mechanism may be a device such as an air cylinder or a hydraulic cylinder, or the lifting mechanism may also be a linear motor, and the supporting platform connected to the lifting mechanism may be lifted or lowered by controlling the lifting mechanism to perform lifting or lowering actions. In order to ensure that the supporting platform has relatively high stability relative to the mounting base 2 in the third direction, the number of the lifting mechanisms can be at least three, and the at least three lifting mechanisms are distributed at intervals in the direction around the third direction.

As above, a plurality of heaters are distributed along the first direction, the mounting base 2 is movably matched with the base in the first direction, the heating channel of the heater extends along the second direction, and the support table is movably matched with the mounting base 2 in the third direction. In order to reduce the control difficulty of the heater switching device and improve the movement precision of the heater switching device, any two of the first direction, the second direction and the third direction can be perpendicular to each other. More specifically, the first direction may be a direction Y in fig. 4, the second direction may be a direction X in fig. 4, and the third direction may be a direction Z in fig. 4.

As shown in fig. 5 and 6, two heaters 100 may be supported on the heater switching device at intervals in the first direction, and the apertures of the heating passages of the two heaters 100 are different. Therefore, in the process of heating the oil pipe 200 with a relatively small diameter, the heater 100 on the right side can be made to correspond to the production line, the oil pipe 200 is made to extend into the heating channel of the heater 100, and the oil pipe is heated by the heater 200. Accordingly, in the case that the oil pipe 200 having a relatively large diameter needs to be heated, the heater 100 corresponding to the production line may be switched by the heater switching device, that is, the heater 200 located on the left side is switched to the position corresponding to the production line, so that the heater 100 having a relatively large diameter of the heating passage can provide the heating function for the oil pipe 200.

In addition, in the process of switching the heater corresponding to the production line, in order to prevent the switching process from being possibly obstructed by the production line, a lifting mechanism is further arranged between the supporting table and the mounting base 2, and the lifting mechanism can drive the supporting table to move along the third direction relative to the mounting base 2. Furthermore, before the heater is switched, the lifting mechanism can drive the supporting platform to descend so as to avoid a production line; then, the mounting base 2 can be moved along a first direction relative to the base, and the required heater can be switched to a position corresponding to the production line; afterwards, the lifting mechanism can be utilized to drive the supporting table to lift, the heater corresponds to the production line in the third direction, and the oil pipe processed by the production line can be guaranteed to stretch into the heating channel of the corresponding heater to be heated.

More specifically, the rotating shaft 25 may extend in the second direction, and considering that the heater switching device has a relatively larger size in the first direction, the rotating shaft 25 may extend in the first direction, which may also prevent the rotating shaft 25 from interfering with other components in the heater switching device as much as possible, and by extending the end of the rotating shaft 25 away from the first coupling 24 to the outside of the mounting seat 2 and the base, prevent the rotation of the handwheel 27 from interfering with other devices, and reduce the difficulty of operating the handwheel 27.
