Description

Technical Field

[0001] This utility model relates to the technical field of air-cooled tube bundle body, specifically an air-cooled tube bundle lifting device. Background Technology

[0002] While the technology and operational experience in the thermal power generation industry have matured, the micro-application of new technologies, processes, and equipment in engineering construction can change traditional construction methods and revitalize outdated approaches. In the process of anti-freezing type A direct air-cooled construction, it is required that the air-cooled tube bundle of the cooling triangular unit be installed at an angle.

[0003] The prior art patent document CN206857963U provides an air-cooled tube bundle lifting device, including a truck crane hook, a tube bundle lifting beam, and an air-cooled tube bundle body. Its characteristic is that a left upper lifting lug and a right upper lifting lug are respectively provided on both sides of the top surface of the tube bundle lifting beam, and a left lower lifting lug and a right lower lifting lug are respectively provided on both sides of the bottom surface of the tube bundle lifting beam. An upper lifting strap passes through the left upper lifting lug and the truck crane hook in sequence and connects to the right upper lifting lug. The upper end of the air-cooled tube bundle body is connected to the left lower lifting lug via the left lower lifting strap, and the lower end of the air-cooled tube bundle body is connected to the right lower lifting lug via the right lower lifting strap. This utility model utilizes lifting ropes of different lengths at both ends of the object being lifted, causing the object to be in an inclined state after lifting. The Pythagorean theorem is used to calculate the lengths of the ropes at both ends, allowing the air-cooled tube bundle body to be directly positioned in one step.

[0004] Although the device has many benefits, the following problems still exist: once the hoisting rope is fixed, the rope length cannot be changed. If the measurement is wrong, the rope needs to be replaced directly, which affects the efficiency of use.

[0005] When hoisting the air-cooled tube bundle body, the device uses double-sided lifting lugs in conjunction with rope hoisting. This can be affected by environmental factors such as wind, causing swaying, which not only affects hoisting efficiency but may also pose safety risks. Utility Model Content

[0006] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0007] 1. Technical problems to be solved:

[0008] To address the issue mentioned above where the length of the hoisting rope cannot be changed after the device is fixed, and if the measurement is incorrect, the rope needs to be replaced directly, affecting the efficiency of use;

[0009] When hoisting the air-cooled tube bundle body, the device uses double-sided lifting lugs in conjunction with rope hoisting. However, it is subject to swaying due to environmental factors such as wind, which affects hoisting efficiency and may also pose safety risks. Therefore, this utility model was proposed.

[0010] Therefore, the purpose of this utility model is to provide an air-cooled tube bundle lifting device that can change the ratio of the lengths of the ropes at both ends and stabilize the air-cooled tube bundle body during lifting.

[0050] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0051] This utility model provides an overall structural schematic diagram of an embodiment of an air-cooled tube bundle lifting device, including:

[0052] Please see Figures 1-5 An air-cooled tube bundle lifting device according to this embodiment includes: an air-cooled tube bundle body 1 and a tube bundle lifting beam 2, with the tube bundle lifting beam 2 disposed above the air-cooled tube bundle body 1.

[0055] The limiting mechanism 200 is installed at the connection between the air-cooled tube bundle body 1 and the tube bundle hoisting beam 2. The limiting mechanism 200 can stabilize the connection between the air-cooled tube bundle body 1 and the tube bundle hoisting beam 2.

[0056] The positioning mechanism 300 is installed at the connection between the lifting beam 3 and the tube bundle lifting beam 2. The positioning mechanism 300 can stabilize the connection between the lifting beam 3 and the tube bundle lifting beam 2.

[0057] It is worth noting that, specifically, for adjustment purposes, the air-cooled tube bundle body 1 is provided with lifting straps 11 at both ends; the adjustment mechanism 100 includes: a groove a101, which is opened through the tube bundle lifting beam 2;

[0058] Groove b102, groove b102 is opened through the side wall of tube bundle hoisting beam 2;

[0061] An adjusting wheel 105 is rotatably disposed in a groove a101, and a fixed shaft 104 passes through the adjusting wheel 105.

[0062] Multiple auxiliary wheels a106 are rotatably connected to both ends of the groove a101. The auxiliary wheels a106 can prevent the traction rope a108 from getting tangled during adjustment.

[0077] 2: After passing the traction rope c303 around the positioning wheel 301 and fixing it to the auxiliary wheel d302, lift the lifting beam 3. The tube bundle lifting beam 2 and the air-cooled tube bundle body 1 will be lifted. Under the action of the traction rope a108, the air-cooled tube bundle body 1 will tilt. At this time, the traction rope b205 will rotate along the rotating shaft 203 with the limit wheel 202 under the action of force. Adjust the ratio of the traction rope b205 and maintain it. At the same time, the traction rope c303 will also rotate at the bottom of the lifting beam 3 with the positioning wheel 301. Adjust the ratio of the traction rope c303 and maintain it.
