[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] As Figures 1 to 5 shown, the present utility model provides a new type of shell-and-tube heat exchanger, including a tubular heat exchanger 1. A base 2 is attached and arranged below the outer side of the tubular heat exchanger 1. A receiving frame 3 is rotatably arranged on the left side of the top end of the base 2. The base 2 cooperates with the receiving frame 3 to support and limit the tubular heat exchanger 1. A jacking assembly 4 is further included on the right side of the base 2;

[0028] The jacking assembly 4 includes a side frame 41 rotatably arranged inside the base 2. A support frame 43 is rotatably arranged at the top end of the side frame 41. A hydraulic pusher 44 is fixedly arranged at the top end of the support frame 43, and the end of the hydraulic pusher 44 abuts against the tubular heat exchanger 1. The side frame 41 in the structure of the jacking assembly 4 that can rotate inside the base 2 can be pushed by the hydraulic pusher 44 to control the deflection of the side frame 41 and simultaneously push the tubular heat exchanger 1.

[0029] Specifically, a fixed shaft 42 is rotatably arranged on the outer side of the support frame 43, and the fixed shaft 42 is fixedly arranged with the base 2. The structure of the fixed shaft 42 can connect and support the support frame 43, keep the support frame 43 stable, support the hydraulic pusher 44, and push the tubular heat exchanger 1.

[0030] Furthermore, a buffer seat 45 is fixedly arranged at the bottom end of the side frame 41, and the buffer seat 45 is in contact with the base 2. A first spring 46 is sleeved outside the buffer seat 45, and the first spring 46 is located between the side frame 41 and the buffer seat 45. The first spring 46 and the buffer seat 45 are at the bottom of the side frame 41, and buffering is carried out between the side frame 41 and the base 2.

[0031] Furthermore, a transmission shaft 5 is rotatably arranged at the bottom end of the receiving frame 3, and the other end of the transmission shaft 5 is rotatably provided with a slider 6, and the slider 6 is slidably arranged with the base 2. After the receiving frame 3 is subjected to gravity, it can push the transmission shaft 5 to push the slider 6 to slide inside the base 2.

[0032] It should be noted that a horizontal shaft 7 penetrates through the slider 6, and the horizontal shaft 7 is fixedly arranged with the base 2. A second spring 8 is sleeved outside the horizontal shaft 7, and the second spring 8 is located between the base 2 and the slider 6. The slider 6 slides outside the horizontal shaft 7, squeezing the second spring 8 to deform, achieving a buffering and pushing effect on the slider 6.

[0033] It should be noted that a baffle 9 is slidably arranged through the top end inside the receiving frame 3. A third spring 11 is fixedly arranged at the bottom end of the baffle 9, and the other end of the third spring 11 abuts against the receiving frame 3. The baffle 9 is connected to the inside of the receiving frame 3 through the third spring 11.

[0034] It should be introduced that a pulling block 12 is fixedly arranged on the left side of the baffle 9, and the pulling block 12 is slidably arranged with the receiving frame 3. A pulley 10 is rotatably arranged at the top end of the baffle 9. Pulling the pulling block 12 can control the opening or closing of the baffle 9. Removing the tubular heat exchanger 1, the pulley 10 structure contacts the tubular heat exchanger 1, achieving a buffering contact effect.

[0035] Among them, the tubular heat exchanger 1 and the hydraulic pusher 44 are prior arts and will not be elaborated; at the same time, the present utility model also includes a power supply, a controller, a switch, etc., which are not the main technical points of this patent and will not be elaborated.

[0036] Working principle and process:

[0037] When the staff installs the tubular heat exchanger 1 inside the base 2, the receiving frame 3 can be rotated to control its rotation on the base 2 to a position close to the ground. Then, the tubular heat exchanger 1 is pushed along the receiving frame 3 to the upper part, so that it can be more conveniently pushed into the inside of the base 2. Press the side frame 41 in the jacking component 4 inside the base 2 to rotate, and press the side frame 41 tightly into the inside of the base 2. The compression deformation of the buffer seat 45 and the outer spring 46 can be used to buffer and support the tubular heat exchanger 1 when it is placed inside the base 2 to keep it stable, and then the assembly is completed and the normal heat exchange operation can be carried out. During the use process, when the tubular heat exchanger 1 is damaged or leaks, the hydraulic pusher 44 on the support frame 43 in the jacking component 4 can be controlled to work. The support frame 43 can be positioned by the outer fixed shaft 42 to support the hydraulic pusher 44, and the tubular heat exchanger 1 can be pushed to move from inside the base 2. The rotation of the side frame 41 can be controlled, and with the elastic push provided by the spring 46, the tubular heat exchanger 1 can be pushed and jacked out from inside the base 2, and the tubular heat exchanger 1 can be jacked up to the position of the receiving frame 3. The receiving frame 3 is affected by gravity and starts to rotate, driving the transmission shaft 5 at the bottom of the receiving frame 3 to rotate, which can drive the slider 6 to slide outside the cross shaft 7 and squeeze the spring 8 outside the cross shaft 7 for buffering to protect the receiving frame 3. The receiving frame 3 supports the tubular heat exchanger 1 through the baffle 9 inside the top end, and the receiving frame 3 is rotated until it reaches the maintenance device, and the tubular heat exchanger 1 above is pushed onto the maintenance machine tool for maintenance. The baffle 9 can be controlled to be retracted or opened by pulling the pull block 12 to form a positioning structure in different states, and with the pulley 10 structure, the movement of the tubular heat exchanger 1 can be protected to reduce friction.

[0038] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
