In order to facilitate understanding of the technical scheme of the utility model, the structure of the plate heat exchanger is simply introduced. The plate heat exchanger mainly comprises plates, compression plates clamped on two sides of the plates and clamping bolts connected between the compression plates, and the plates can be clamped and fixed by adjusting the clamping bolts. The surfaces of the hold-down plates of the plate heat exchanger are usually pre-perforated with process holes.
When the plate heat exchanger is disassembled, the frame 1 is pushed to be close to the plate heat exchanger, the transverse position of the frame 1 relative to the plate heat exchanger is adjusted, then the position of the first installation part 2 in the vertical direction is adjusted through the first driving device 21, the transverse position of the second installation part 3 relative to the process hole is further adjusted through the second driving device 31, the frame 1 is continuously pushed to advance until the supporting rod 41 is coincident with the axis of the process hole, the supporting rod 41 is inserted into the process hole, finally the plate heat exchanger can be disassembled from the equipment, the plate heat exchanger is lapped on the supporting rod 41 due to gravity, the frame 1 is controlled to retreat, and the plate heat exchanger is conveyed to a designated position.

Referring to fig. 2, the connection part 4 is further provided with a positioning hole 42. The distance between the positioning holes 42 and the support bar 41 should be set according to the size and type of the plate heat exchanger such that when the support bar 41 is aligned with the positioning holes 42, the positioning holes 42 are exactly aligned with the ends of the clamping bolts on the plate heat exchanger. Thus, when the support bar 41 is inserted into the process hole, the clamping bolt is inserted into the positioning hole 42. By the arrangement of the positioning holes 42, the number of supporting points between the connecting portion 4 and the plate heat exchanger is increased, so that the stability of the plate heat exchanger relative to the connecting portion 4 can be improved.

Referring to fig. 1, 3 and 4, as a possible implementation of the present utility model, a pose adjustment unit 5 is further provided between the second mounting portion 3 and the connecting portion 4. When the frame 1 is pushed to approach the plate heat exchanger under the influence of the space position factor, the position of the connecting part 4 may deviate from the plate heat exchanger in the transverse direction, and the transverse position of the connecting part 4 is further adjusted by mutually matching the pose adjusting unit 5 with the second mounting part 3 so as to ensure that the supporting rod 41 can be accurately abutted with the positioning hole 42.

When the second mounting portion 3 is adjusted to the supporting rod 41 to be capable of basically overlapping with the positioning hole 42, the rotating arm 51 is controlled to rotate, so that the supporting rod 41 is accurately abutted with the positioning hole 42. By adopting the above mode, on one hand, the space position influence factor can be overcome, on the other hand, the transverse position of the supporting rod 41 is adjusted by matching the rotating arm 51 with the second installation part 3, and under the condition that the supporting rod 41 and the positioning hole 42 can be in butt joint by utilizing the rotating arm 51, the second installation part 3 is prevented from deviating from the middle position of the frame 1 too much. When the second mounting part 3 is positioned at the middle position of the frame 1, the rotation arm 51 is used for adjusting, and the gravity applied by the plate heat exchanger is transmitted to the second mounting part 3 through the rotation arm 51, so that the phenomenon that the frame 1 is toppled down due to the fact that the action point of the gravity is seriously deviated from the center of the frame 1 can be avoided.
Alternatively, the first end 511 is fixedly provided with a first hinge shaft 513 in a first direction, and the second end is fixedly provided with a second hinge shaft 514 in the first direction. The first hinge shaft 513 is hinged to the second mounting portion 3, and the second hinge shaft 514 is hinged to the connecting portion 4. Optionally, the first direction is vertical.
The first hinge shaft 513 and the second hinge shaft 514 are vertically provided, and the first hinge shaft 513 and the second hinge shaft 514 are provided within a proper length range so as to be able to bear the gravity from the plate heat exchanger, thereby ensuring the stability of the posture adjustment unit 5.
