Description

Technical Field

[0001] The utility model relates to the technical field of heat exchanger plate clamping, in particular to a semi-automatic heat exchanger plate clamping and lifting device. Background Art

[0002] In the traditional process of lifting and transferring heat exchangers, the use of hooks is a crucial link, but it also faces many challenges.

[0003] First, the worker carefully adjusts and precisely secures the bottom hook on the support rod. Then, based on the actual length of the heat exchanger to be clamped, the worker manually adjusts the height of the top hook. Once the position and height of both the bottom and top hooks are adjusted, the worker carefully places the heat exchanger into the reserved space between them. Finally, the top hook is securely fastened to the support rod using bolts and other fasteners and then transferred to the storage rack.

[0004] If the distance between the top hook and the bottom hook is not adjusted properly, uneven force may be applied to the heat exchanger during the clamping process. If the bolts are too tight, the heat exchanger may be compressed and deformed. If they are too loose, sufficient clamping force cannot be provided, causing the heat exchanger to become unhooked multiple times during the lifting and transfer process.

[0005] Therefore, the entire process of clamping the heat exchanger plate is not only multi-step and complicated, but also seriously reduces the production efficiency of the heat exchanger plate. Utility Model Content

[0006] In response to the above-mentioned defects, the utility model proposes a semi-automatic heat exchanger plate clamping and lifting device, which not only quickly adjusts the distance between the movable hook and the fixed hook, but also quickly and firmly clamps the heat exchanger plate, solving the problem that the traditional clamping of heat exchanger plates has many and cumbersome steps and low clamping efficiency.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, unless otherwise specified, "plurality" means more than two.

[0032] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "installation," "splicing," and "connection" should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integral connection; they may refer to direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0033] The following combination Figures 1 to 3 , describing a semi-automatic heat exchanger fin clamping and lifting device according to an embodiment of the present utility model.

[0034] A semi-automatic heat exchanger fin clamping and lifting device comprises a support rod 1, a fixed hook 2 is fixedly mounted on the bottom of the support rod 1, a movable mounting block 3 is slidingly sleeved on the top of the support rod 1, a movable hook 4 is rotatably mounted on the movable mounting block 3, and the movable hook 4 and the fixed hook 2 jointly clamp the heat exchanger fin;

[0035] A support mounting block 5 is provided in the middle of the support rod 1, and a handle 8 is rotatably mounted on the support mounting block 5. The handle 8 is connected to the end of the movable hook 4 away from the heat exchange plate through a connecting component 6. When the handle 8 is rotated downward, the end of the movable hook 4 close to the heat exchange plate is tilted upward;

[0036] A locking assembly is provided between the handle 8 and the movable hook 4 , and the locking assembly is used to limit the rotation of the handle 8 and the movable hook 4 .

[0037] Since the bottom of the support rod 1 is provided with a fixed hook 2, the staff only needs to turn the handle 8 downward, and the handle 8 drives the connecting assembly 6 to move downward. The connecting assembly 6 can drive the end of the movable hook 4 close to the heat exchange plate to tilt upward, so that the distance between the fixed hook 2 and the movable hook 4 becomes larger, ensuring that the heat exchange plate can be located between the fixed hook 2 and the movable hook 4. Then, the handle 8 is turned upward, and the handle 8 drives the connecting assembly 6 to move upward. The connecting assembly 6 drives the end of the movable hook 4 close to the heat exchange plate to tilt downward, ensuring that the fixed hook 2 and the movable hook 4 cooperate with each other to jointly clamp the two ends of the heat exchange plate.

[0038] At this time, the staff can control the movement of the movable hook 4 by simply turning the handle 8, without the need for complicated operating steps or additional tools, which reduces the difficulty of operation and makes it easy for non-professionals to get started.

[0039] The locking assembly between the handle 8 and the movable hook 4 can limit the rotation of the handle 8 and the movable hook 4, ensuring the stability and safety of the heat exchange plate during the clamping process, and effectively avoiding the heat exchange plate from falling off or being damaged due to accidental operation or vibration.

[0040] In addition, the movable hook 4 is rotatably installed on the movable mounting block 3 which is sleeved on the supporting rod 1, so that the position of the movable mounting block 3 can be adjusted according to the size of the heat exchange sheet, and the semi-automatic heat exchange sheet clamping and lifting device can be adapted to heat exchange sheets of different sizes.

[0041] Therefore, the semi-automatic heat exchange sheet clamping and lifting device can quickly and stably clamp the heat exchange sheet through the cooperation of the movable mounting block 3, the handle 4 and the locking assembly, and solves the problems of multiple and complicated clamping steps and low clamping efficiency of the conventional heat exchange sheet clamping device.

[0042] The locking assembly comprises a first reset spring 71 and a second reset spring 72.

[0043] The movable hook 4 comprises a clamping portion 41 and a mounting portion 42, the clamping portion 41 clamps the heat exchange sheet together with the fixed hook 2, the mounting portion 42 is rotatably installed at the center of the movable mounting block 3, the end of the mounting portion 42 away from the clamping portion 41 is hingedly connected to the connecting assembly 6, and the side wall of the mounting portion 42 is connected to the top of the movable mounting block 3 through the first reset spring 71.

[0044] The side wall of the supporting mounting block 5 is connected to the top of the handle 8 through the second reset spring 72.

[0045] When the handle 8 is rotated downward, the second reset spring 72 is stretched and deformed, and the mounting portion 42 moves downward, and the first reset spring 71 is stretched and deformed, so that the heat exchange sheet can be located in the space between the fixed hook 2 and the clamping portion 41.

[0046] When the handle 8 is released, the second reset spring 72 restores the deformation and can automatically push the handle 8 back to its original position, preparing for the next operation. At the same time, the first reset spring 71 can provide a restoring force to make the mounting portion 42 move upward to the locking position, and the clamping portion 41 moves downward to clamp the heat exchange sheet, thereby reducing the operation difficulty and labor intensity of the worker in clamping the heat exchange sheet.

[0047] The first reset spring 71 and the second reset spring 72 interact with each other, so that the clamping portion 41 of the movable hook 4 can be more closely matched with the fixed hook 2, thereby enhancing the clamping force of the heat exchange sheet and preventing the heat exchange sheet from accidentally falling off due to improper operation or external interference.

[0048] The connecting assembly 6 comprises a first connecting rod 61, a second connecting rod 62 and a reset member 64, the top of the first connecting rod 61 is hingedly connected to the mounting portion 42, the bottom of the first connecting rod 61 movably extends into the inner wall of the vertical second connecting rod 62, and the bottom of the second connecting rod 62 is hingedly connected to the handle 8.

[0049] A reset member 64 is provided on the outer wall of the first connecting rod 61 , and a plurality of vertically arranged first limiting holes 65 are provided on the side wall of the second connecting rod 62 . The reset member 64 movably extends out of one of the first limiting holes 65 .

[0050] The hinged connection between the first connecting rod 61 and the mounting portion 42, and the hinged connection between the second connecting rod 62 and the handle 8, allows the entire connecting assembly 6 to flexibly transmit the rotation of the handle 8 to the movable hook 4, thereby clamping and releasing the heat exchanger. This design allows the operator to adjust the rotation angle of the movable hook 4 by simply turning the handle 8, thereby accommodating heat exchangers of different sizes and shapes.

[0051] The first connecting rod 61 movably extends into the inner wall of the second connecting rod 62, and is limited and locked by the cooperation of the reset member 64 and the first limiting hole 65. When clamping heat exchangers of other sizes, the staff flexibly adjusts the position of the movable mounting block 3 on the support rod 1 and presses the reset member 64 so that the reset member 64 extends into the inner wall of the second connecting rod 62. The relative position between the first connecting rod 61 and the second connecting rod 62 is then adjusted up and down. At this time, the reset member 64 movably extends into the corresponding first limiting hole 65, thereby fixing the distance between the handle 8 and the movable hook 4, ensuring that the staff can adjust the movable state of the movable hook 4 through the connecting assembly 6.

[0052] The first connecting rod 61 is provided with an inwardly recessed receiving groove, which is arranged opposite to the first limiting hole 65. A horizontal limiting spring 66 is provided inside the receiving groove, and the end of the limiting spring 66 is connected to the reset member 64.

[0053] A side of the reset member 64 close to the second connecting rod 62 is provided with an arc surface.

[0054] Pressing the reset member 64 causes it to move inward, compressing the limit spring 66 and extending it into the receiving slot, ensuring that the first connecting rod 61 can move freely. When the reset member 64 is positioned opposite one of the first limit holes 65, the limit spring 66 recovers its deformation and pushes the reset member 64 outward, aligning the reset member 64 with the corresponding first limit hole 65 and accurately engaging it, thereby locking the connecting assembly 6. The use of the limit spring 66 in this solution simplifies the adjustment process of the connecting assembly 6 and reduces the possibility of malfunction or damage caused by improper operation.

[0055] In addition, a circular arc surface is provided on the side of the reset member 64 close to the second connecting rod 62. The circular arc surface can not only reduce the friction and collision of the reset member 64 when it is inserted into and exits the first limiting hole 65, but also improve the user experience of the staff.

[0056] The side wall of the support rod 1 is provided with a plurality of vertically arranged second limiting holes 11, and the movable mounting block 3 is movably mounted with a horizontal first latch 12, which movably extends into the second limiting hole 11;

[0057] The support and installation block 5 is movably provided with a horizontal second latch 51 , and the second latch 51 movably extends into the second limiting hole 11 .

[0058] In order to better and more conveniently adjust the height of the movable mounting block 3, the operator only needs to movably insert the first pin 12 into the second limiting hole 11 of the required height to fix the movable mounting block 3 in the corresponding position. Without complicated operating steps or additional tools, the semi-automatic heat exchanger clamping and lifting device of this solution can adapt to heat exchangers of different sizes and achieve precise clamping and lifting.

[0059] When the first latch 12 is inserted into the second limiting hole 11 and locked, it provides a stable support point, preventing the movable mounting block 3 from shaking or shifting during the clamping process. Furthermore, the second latch 51 allows the operator to adjust and secure the position of the supporting mounting block 5. The mechanical locking mechanism of the latch and the second limiting hole 11 enhances the stability of the movable mounting block 3 and the supporting movable block on the support rod 1.

[0060] The distance between two adjacent first limiting holes 65 is consistent with the distance between two adjacent second limiting holes 11 .

[0061] Because the spacing between adjacent first limiting holes 65 and second limiting holes 11 is consistent, this allows for precise alignment between the movable mounting block 3 and the connecting assembly 6. For example, by determining the number of second limiting holes 11 passed by the first latch 12 during movement and simultaneously moving the corresponding number of first limiting holes 65, the height of the movable mounting block 3 and the connecting assembly 6 can be quickly adjusted to accommodate heat exchange fins of different sizes.

[0062] A vertical mounting ring 9 is fixedly provided on the top of the support rod 1 .

[0063] When storing the heat exchanger, the staff only needs to put the mounting ring 9 on the top of the support rod 1 on the fixed mounting support point to store the heat exchanger vertically, thereby improving the convenience of storing the heat exchanger.

[0064] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
