Description

Technical Field

[0001] The present invention relates to the field of glass-lined equipment hoisting, in particular to a large-scale glass-lined equipment firing crane. Background Art

[0002] Large-scale glass-lined equipment is a corrosion-resistant reaction vessel commonly used in the chemical, pharmaceutical, and food industries. It utilizes a glass enamel layer sintered at high temperatures onto a metal substrate (usually carbon steel or cast iron), combining the strength of metal with the chemical stability of glass. Existing large-scale glass-lined equipment typically requires specialized cranes for transport after manufacture. Currently, large-scale glass-lined equipment cranes typically utilize only a hook and a rope for lifting. This method can cause the equipment to shake during lifting due to environmental factors such as wind and rain. Furthermore, after sintering, glass-lined equipment is very fragile, and excessive shaking can cause the equipment to break. This is especially true during port transshipment, where remote control systems are used to assist in operations. The more complex port environment significantly increases the probability of equipment breakage caused by shaking during lifting.

[0003] For example, the Chinese utility model patent (application number: CN202421147875.X) discloses a "large-scale glass-lined equipment firing hanger." Its description discloses that glass-lined equipment is used to manufacture glass-lined products. Glass-lined is a composite material composed of glass and metal (usually steel), with the transparency of glass and the strength of metal. The process of manufacturing glass-lined products includes preparing the substrate, applying glass glaze, baking, and cooling. Existing glass-lined firing hangers typically use hooks connected to a crane, which then uses two hooks hooked to high-temperature-resistant ropes to lift the equipment. However, the crane and hooks are connected by ropes, which causes shaking during lifting. Moreover, glass-lined equipment is very fragile after firing. Excessive shaking can lead to manufacturing failure. Therefore, a large-scale glass-lined equipment firing hanger is needed. The above patent can demonstrate the shortcomings of the existing technology.

[0004] Therefore, we made improvements to this and proposed a large-scale glass-lined equipment firing crane. Summary of the Invention

The connecting block 22 extends to the outside of the counterweight box 20, and thread grooves 23 are symmetrically provided on both sides of the connecting block 22. The two sets of thread grooves 23 are staggered. Bolts 21 are symmetrically provided on the outside of the counterweight box 20. The bolts 21 penetrate the side wall of the counterweight box 20 and are threadedly connected to the thread grooves 23. The connecting block 22 is provided to cooperate with the thread grooves 23 on both sides and the bolts 21 to facilitate the splicing of the counterweight box 20, which is then used to increase the counterweight or splice two sets of hook assemblies 4.

[0048] Please refer to Figure 13 、 Figure 14 and Figure 15 The hydraulic cylinders 27 are spaced apart from the guide shaft 14, and universal joints 29 are fixedly installed at the upper and lower ends of the hydraulic cylinders 27. The hydraulic cylinders 27 are fixedly connected to the bottom of the sleeve ring plate 5 and the top of the mounting plate 31 through the universal joints 29 installed at both ends. The hydraulic cylinders 27 are connected through the universal joints 29, which makes it convenient to adjust the angles of the six groups of hydraulic cylinders 27 through the universal joints 29 when they are extended to different lengths, thereby facilitating the change of the lifting angle.

[0049] A mechanical lock pin 28 for locking the hydraulic cylinder 27 is fixedly installed in the middle of the outer side of the hydraulic cylinder 27, and a connecting ring 30 is sleeved on the bottom of the outer side of the hydraulic cylinder 27, and an elastic steel rope 25 is fixedly installed on the outer side of the connecting ring 30, and the other ends of the two groups of elastic steel ropes 25 are respectively fixedly connected to the side walls of the counterweight box 20 located on both sides of the above-mentioned hydraulic cylinder 27; the installed elastic steel ropes 25 facilitate the limiting connection of the counterweight box 20, and at the same time, it can achieve buffering when the counterweight box 20 shakes.

[0050] A circular groove 34 is provided at the center of the top of the mounting disk 31. A servo motor 33 is fixedly mounted on the top of the mounting disk 31, and the output end of the servo motor 33 extends through the circular groove 34 to its bottom.

[0053] A connecting steel rope 26 is fixedly installed on the outer side of the arc plate 37, and the other end of the connecting steel rope 26 is connected to the inner side of a set of mounting shafts 19 (refer to Figure 8 ), as the arc plate 37 rotates, the connecting steel rope 26 becomes loose, thereby facilitating the shaking of the mounting shaft 19.

[0054] Example 2, further optimizes the large glass-lined equipment firing crane provided in Example 1, specifically, Figure 10 、 Figure 11 and Figure 12 As shown, the connecting block 22 cooperates with the bolt 21 and the threaded groove 23 to facilitate the splicing of the counterweight box 20, thereby realizing the splicing of different hook assemblies 4.

[0055] The use process of the large-scale glass-lined equipment firing crane provided by the present invention is as follows:

[0056] When in use, before lifting, it is necessary to first select a ballast block of appropriate weight according to the weight of the glass-lined equipment and its placement position, and evenly place it inside the six groups of ballast boxes 20, and then select the position for installing the first hook 40 and the second hook 41 according to the placement position of the glass-lined equipment. During installation, if the lifting position is good, only the first hook 40 can be installed. If the lifting position is not good, the second hook 41 can be installed for auxiliary lifting. At this time, it is necessary to pay attention to the placement position of the ballast block. The tilting weight of the ballast block needs to offset the tilting weight generated by the second hook 41, or form a certain angle. This angle needs to be the same as the tilt angle of the glass-lined equipment, thereby ensuring that there is no shaking during lifting. Then, the port container crane remote control system is used to perform the lifting operation, and the port container crane remote control system is used to cooperate with the sensors installed at each joint position of the crane body 1 to judge the real-time status of the crane body 1;

[0057] Slight shaking: When the glass-lined equipment is hoisted in the air and shakes due to a breeze, the mechanical lock pin 28 on the outside of the hydraulic cylinder 27 can be opened. At this time, when the wind blows on the hook assembly 4 and the glass-lined equipment, the shaking can be buffered by the hydraulic cylinders 27 arranged in the array, thereby avoiding the influence of the wind. At the same time, the hydraulic cylinders 27 can also be disabled. In this case, the wind is first guided by the first guide plate 6, the guide shaft 14 and the spiral spoiler 15 on the outside of the sleeve ring plate 5, and then diverted through the air guide holes 7 opened through the side wall of the sleeve ring plate 5 and the wind grooves 16 opened through the side wall of the guide shaft 14, thereby reducing the shaking caused by the wind.

[0058] The shaking is aggravated. As the wind force continues to increase, the shaking of the hook assembly 4 and the glass-lined equipment also increases. At this time, the servo motor 33 can be slowly started, and the output end thereof drives the rotating disk 35 and the arc plate 37 installed in the array on its outer side to rotate, thereby driving the first hook 40 and the second hook 41 to rotate. As the arc plate 37 continues to rotate, the connecting steel rope 26 connected to its outer side is continuously loosened. At this time, the connecting steel rope 26 no longer pulls the mounting shaft 19, so the mounting shaft 19 will be separated from the mounting disk 31 under the action of gravity and wind force. At this time, the mounting shaft 19 arranged in the array cooperates with the counterweight box 20 and the counterweight blocks filled therein to form a counterweight in a free-fall state, and then the shaking of the counterweight box 20 in the free-fall state can be used to convert the wind force into a swinging force of the counterweight box 20, thereby maintaining stability.

[0059] The swaying intensifies again. At this time, the swing amplitude of the counterweight box 20 increases again and swings to the extreme under the fibers of the elastic steel rope 25. At this time, the wind force forces the glass-lined equipment and the hook assembly 4 to sway. The torsional force generated by the swaying is transmitted through the sleeve ring plate 5 to the hydraulic buffer 12 installed in the array inside it, forcing the hydraulic buffer 12 installed in the array to produce different degrees of expansion and contraction. The hydraulic buffer 12 converts the wind force into pressure of the hydraulic buffer 12, thereby dispersing the wind force and reducing its impact.

[0060] When the sway reaches its limit, all of the above components provide flow diversion and buffering, while also cooperating with the port container crane remote control system to read the real-time status of the crane body 1, determine the sway direction of the hook assembly 4 and the glass-lined equipment, and then start the servo motor 33. The servo motor 33 drives the first hook 40 and the second hook 41 to rotate through the rotating disk 35 and the arc plate 37 installed at its output end, thereby driving the glass-lined equipment to rotate, so that it conforms to the wind direction, thereby reducing the amplitude of the glass-lined equipment sway;

[0061] If the wind at the port is too strong and causes the crane body 1 to shake, the servo motor 33 is started in reverse to reset the guide shaft 14, and the taut connecting steel rope 26 and the side groove 32 are used to limit the guide shaft 14. Then all the hydraulic cylinders 27 are retracted to reduce the gap between the sleeve ring plate 5 and the mounting plate 31. After the retraction is completed, it is ensured that the hydraulic cylinders 27 are completely locked by the mechanical locking pin 28. Then, multiple sets of counterweight boxes 20 can be used, in conjunction with the connecting blocks 22 and bolts 21 provided on the outside thereof, to splice the hook assemblies 4 of the two sets of cranes, thereby increasing the connection between the two sets of crane bodies 1 and jointly resisting the hurricane.
