Description

Technical Field

[0001] The present invention relates to the field of lifting enamel equipment, and more specifically, to a firing crane for large enamel equipment. Background Art

[0002] Large enamel equipment is a commonly used corrosion-resistant reaction vessel in industries such as chemical engineering, pharmaceuticals, and food. It sinteres a glass enamel layer at high temperature on a metal (usually carbon steel or cast iron) substrate, combining the strength of the metal and the chemical stability of the glass. After the existing large enamel equipment is manufactured, when it is transported, a special crane is usually required to lift it for transportation. Currently, the large enamel equipment cranes used in reality usually only use the hook of the crane in combination with a lifting rope for connection during the lifting operation. This method will cause the large enamel equipment to shake during lifting due to environmental influences such as strong winds and rain. Moreover, the enamel is very fragile after firing. If the shaking amplitude is too large, it will cause the equipment to break. Especially during port transfer, during the process of assisting the operation with the remote control system of the port container crane, due to the more complex port environment, the probability of the equipment breaking due to shaking during lifting is greatly increased.

[0003] For example: The "Firing Hanger for Large Enamel Equipment" disclosed in the Chinese utility model patent (Application No.: CN202421147875.X) has a description in its specification: Enamel equipment is equipment used to manufacture enamel products. Enamel is a composite material formed by combining glass and metal (usually steel), with the transparency of glass and the firmness of metal. The process of manufacturing enamel products includes steps such as preparing the base material, coating the glass glaze, baking, and cooling. The existing enamel firing hangers usually connect the crane with a hook, and then lift the equipment by hooking two hooks to high-temperature-resistant ropes. However, the crane and the hook are connected by a rope, which causes shaking during lifting. Moreover, the enamel is very fragile after firing. If the shaking amplitude is too large, it will lead to manufacturing failure. Therefore, a firing hanger for large enamel equipment is needed; the above patent can prove the defects existing in the prior art.

[0004] Therefore, we make improvements and propose a firing crane for large enamel equipment. Summary of the Invention

[0020] To enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] As described in the background art, for the large enamel equipment crane currently used in reality, when lifting operations are carried out, it usually only uses the hook of the crane in cooperation with the lifting rope for connection. This method will cause the large enamel equipment to shake when lifted due to environmental impacts such as strong winds and rain in the external environment. Moreover, the enamel is very fragile after firing. If the shaking amplitude is too large, the equipment will be broken.

[0022] To solve this technical problem, the present invention provides a large enamel equipment firing crane, which is applied to a large enamel equipment firing crane with buffering.

[0023] Specifically, please refer to Figures 1 - 15 , the large enamel equipment firing crane specifically includes a port container crane remote control and a crane body 1 controlled by the system, a lifting rope 2, and a pulley block 3. At the bottom of the pulley block 3, there is a hook assembly 4 for increasing the hoisting stability. The hook assembly 4 includes a central disk 9 arranged at the bottom of the pulley block 3. A socket ring plate 5 is sleeved outside the central disk 9. And a hydraulic cylinder 27 is arranged in an array at the bottom of the socket ring plate 5. The hydraulic cylinders 27 are distributed in a funnel shape. Below the hydraulic cylinders 27, there is an installation disk 31. Exactly below the installation disk 31, there is a first hook 40. And on one side of the first hook 40, there is a second hook 41; By connecting this device to the port container crane remote control, it is convenient to view the working state of the crane body 1 in real time through the cooperation of the port container crane remote control and the sensors installed at each joint of the crane body 1 during operation.

[0024] For the large enamel equipment firing crane provided by the present invention, through the socket ring plate 5 arranged inside the hook assembly 4 in cooperation with the hydraulic cylinders 27 arranged in an array at its bottom, and the mechanical locking pins 28 installed outside the hydraulic cylinders 27, in cooperation with the installation disk 31 arranged at the bottom of the hydraulic cylinders 27, it is convenient to form a degree-of-freedom platform with a short stroke. Then, through the array of hydraulic cylinders 27, buffering is realized. When the enamel equipment shakes, by compressing the hydraulic cylinders 27, the shaking amplitude is reduced.

[0025] To enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings.

[0026] It should be noted that, without conflict, the embodiments in the present invention and the features and technical solutions in the embodiments can be combined with each other.

[0027] It should be noted that like reference numerals and letters indicate like items in the following figures; thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

[0028] Example 1, please refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , a large-scale enamel equipment firing crane, on the outer side of the central disk 9, hydraulic buffers 12 are arranged in an array. Socket shafts 13 are arranged at both ends of the hydraulic buffer 12. The hydraulic buffer 12 is connected to the outer side of the central disk 9 and the inner side of the socket ring plate 5 respectively through the socket shafts 13 arranged at both ends thereof. The hydraulic buffers 12 are inclinedly distributed. By providing the hydraulic buffers 12, it is convenient to buffer when the socket ring plate 5 is subjected to external torsion force through the hydraulic buffers 12. On the outer side of the central disk 9, second guide plates 10 are arranged in an array. The second guide plates 10 are spaced from the hydraulic buffers 12. The second guide plates 10 can continue to conduct the flow, and thus it is convenient to cool the hydraulic buffers 12 in and out. At the center of the top of the central disk 9, a fixing block 11 is fixedly installed. The fixing block 11 is sleeved with the bottom of the pulley block 3. Through holes 7 penetrating through its side wall are uniformly formed on the outer side of the socket ring plate 5. On the outer side of the socket ring plate 5, first guide plates 6 are arranged in an array, and the first guide plates 6 are inclined and spaced from the through holes 7. By providing the through holes 7 in cooperation with the first guide plates 6, air guiding and flow splitting can be achieved.

[0029] As Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 shown, spherical socket parts 8 (refer to Figure 6 ) are arranged in an array at the bottom of the socket ring plate 5. The bottom of the socket ring plate 5 is socketed with a ball head 17 through the spherical socket parts 8. A diversion shaft 14 is fixedly installed at the bottom of the ball head 17. The diversion shaft 14 is inclined and opposite to the inclination direction of the hydraulic cylinder 27. A central groove 18 is formed in the middle of the diversion shaft 14. Air grooves 16 are formed through the outer side of the diversion shaft 14, and the air grooves 16 communicate with the central groove 18. A spiral spoiler 15 is fixedly installed on the outer side of the diversion shaft 14. By providing the diversion shaft 14 and the spiral spoiler 15 installed on its outer side, it is convenient to guide the air flow, thereby reducing its influence.

[0030] At the bottom of the diversion shaft 14, a mounting shaft 19 is fixedly installed. On the outer side of the mounting shaft 19, a counterweight box 20 is fixedly installed. The counterweight box 20 is hollow, and counterweight blocks are filled inside the counterweight box 20. A splicing groove 24 is formed on the outer side of the counterweight box 20. The counterweight box 20 is sleeved with an adapter block 22 through the splicing groove 24. The adapter block 22 extends to the outside of the counterweight box 20. Thread grooves 23 are symmetrically formed on both sides of the adapter block 22, and the two groups of thread grooves 23 are staggeredly distributed. Bolts 21 are symmetrically arranged on the outer side of the counterweight box 20. The bolts 21 penetrate through the side wall of the counterweight box 20 and are threadedly connected with the thread grooves 23. By providing the adapter block 22 and cooperating with the thread grooves 23 and bolts 21 on both sides thereof, it is convenient to splice the counterweight box 20, thereby increasing the counterweight or splicing the two hook assemblies 4.

[0031] Please refer to Figure 13 、 Figure 14 and Figure 15 , in which the hydraulic cylinders 27 and the diversion shaft 14 are spaced apart. Universal joints 29 are fixedly installed at both the upper and lower ends of the hydraulic cylinders 27. The hydraulic cylinders 27 are fixedly connected to the bottom of the socket ring plate 5 and the top of the mounting plate 31 respectively through the universal joints 29 installed at both ends thereof. By connecting the hydraulic cylinders 27 through the universal joints 29, it is convenient to adjust the angle through the universal joints 29 when the six hydraulic cylinders 27 extend and contract by different lengths, thereby facilitating the change of the lifting angle.

[0032] A mechanical locking pin 28 for locking the hydraulic cylinder 27 is fixedly installed in the middle of the outer side of the hydraulic cylinder 27. A connecting collar 30 is sleeved on the bottom of the outer side of the hydraulic cylinder 27, and an elastic steel cable 25 is fixedly installed on the outer side of the connecting collar 30. The other ends of the two elastic steel cables 25 are respectively fixedly connected to the side walls of the counterweight boxes 20 located on both sides of the above-mentioned hydraulic cylinder 27; by installing the elastic steel cables 25, it is convenient to limit and connect the counterweight boxes 20, and at the same time, it can buffer the counterweight boxes 20 when they shake.

[0033] A circular groove 34 is formed at the center of the top of the mounting plate 31. A servo motor 33 is fixedly installed on the top of the mounting plate 31, and the output end of the servo motor 33 penetrates through the circular groove 34 and extends to its bottom. Side grooves 32 are arrayed on the side wall of the mounting plate 31, and the mounting plate 31 is in contact with the mounting shaft 19 through the side grooves 32.

[0034] A rotating disk 35 is installed directly below the mounting plate 31, and the bottom of the rotating disk 35 is connected to the first hook 40 through screws. An installation groove 36 is formed at the center of the top of the rotating disk 35. The rotating disk 35 is fixedly connected to the output end of the servo motor 33 through the installation groove 36. Arc plates 37 are arrayed on the outer side of the rotating disk 35. The ends of the arc plates 37 are in a disk shape, and the bottom of the ends of the arc plates 37 is connected to the second hook 41 through screws.

[0035] A limit slider 38 is fixedly installed at the top of the arc plate 37. A chute 39 is opened at the bottom of the mounting plate 31. The mounting plate 31 is sleeved with the limit slider 38 through the chute 39. The servo motor 33 drives the rotating disc 35 and the arc plate 37 to slide under the limitation of the limit slider 38 and the chute 39, and drives the first hook 40 and the second hook 41 to rotate, facilitating the adjustment of the direction and angle of the hook.

[0036] A connecting steel rope 26 is fixedly installed on the outer side of the arc plate 37. The other end of the connecting steel rope 26 is connected to the inner side of a group of mounting shafts 19 (refer to Figure 8 ), and as the arc plate 37 rotates, the connecting steel rope 26 continuously loosens, thereby facilitating the shaking of the mounting shaft 19.

[0037] Example 2 further optimizes the large-scale enamel equipment firing crane provided in Example 1. Specifically, as shown in Figure 10 、 Figure 11 and Figure 12 , through the cooperation of the connecting block 22, the bolt 21 and the thread groove 23, it is convenient to splice the counterweight box 20, so as to realize the splicing of different hook assemblies 4.

[0038] The use process of the large-scale enamel equipment firing crane provided by the present invention is as follows: During use, before the hoisting work, according to the weight of the enamel equipment and its placement position, first select the counterweight blocks with appropriate weights and evenly place them inside the six counterweight boxes 20. Then, according to the placement position of the enamel equipment, select the positions for installing the first hook 40 and the second hook 41. During installation, if the hoisting position is good, only the first hook 40 can be installed. If the hoisting position is not good, the second hook 41 can be installed for auxiliary hoisting. At this time, attention needs to be paid to the placement position of the counterweight blocks. The inclined weight of the counterweight blocks needs to cancel out the inclined weight generated by the second hook 41, or form a certain included angle, and this included angle needs to be the same as the inclined angle of the enamel equipment, so as to ensure that there is no shaking during hoisting. Then, use the port container crane remote control system to carry out the hoisting operation, and judge the real-time state of the crane body 1 through the port container crane remote control system and the sensors installed at each joint position of the crane body 1; Slight shaking; when the glass-lined equipment is lifted into the air and shakes due to the blowing of a gentle breeze, the mechanical lock pin 28 outside the hydraulic cylinder 27 can be opened. At this time, when the wind blows the hook assembly 4 and the glass-lined equipment to shake, the arrayed hydraulic cylinders 27 can be used for buffering, thus avoiding the influence of the wind. At the same time, the hydraulic cylinders 27 can also not be used. At this time, the wind first passes through the first guide plate 6, the diversion shaft 14, and the spiral spoiler 15 outside the socket ring plate 5 for guiding, and then is shunted through the air guide holes 7 penetrated through the side wall of the socket ring plate 5 and the wind grooves 16 penetrated through the side wall of the diversion shaft 14, thereby reducing the shaking generated by the wind; Increasing shaking, as the wind force continuously increases, 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 its output end drives the rotating disk 35 and the arc plates 37 arrayed outside it to rotate, thereby driving the first hook 40 and the second hook 41 to rotate. As the arc plates 37 continuously rotate, the connecting steel ropes 26 connected to the outside of them are continuously loosened. At this time, the connecting steel ropes 26 no longer pull the mounting shaft 19. Therefore, the mounting shaft 19 will separate from the mounting plate 31 under the action of gravity and wind force. At this time, the arrayed mounting shafts 19 cooperate with the counterweight box 20 and the counterweight blocks filled inside it to form a counterweight in a free-fall state. Furthermore, the shaking of the counterweight box 20 in the free-fall state can be used to convert the wind force into the swinging force of the counterweight box 20, thereby maintaining stability; The shaking intensifies again. At this time, the swinging amplitude of the counterweight box 20 increases again and swings to the extreme under the action of the elastic steel rope 25. At this time, the wind force forces the glass-lined equipment and the hook assembly 4 to shake. The torsion generated by the shaking is transmitted to the hydraulic buffers 12 arrayed inside the socket ring plate 5 through the socket ring plate 5, and forces the arrayed hydraulic buffers 12 to generate different degrees of expansion and contraction. Thus, the wind force is converted into the pressure of the hydraulic buffers 12 through the hydraulic buffers 12, thereby dispersing the wind force and reducing its influence; The shaking reaches the limit. At this time, while guiding and buffering through all the above components, the remote control system of the port container crane can also be coordinated to read the real-time state of the crane body 1 in real time and judge the shaking direction of the hook assembly 4 and the glass-lined equipment. Then, the servo motor 33 is started, and the rotating disk 35 and the arc plates 37 installed at its output end are used to drive the first hook 40 and the second hook 41 to rotate, thereby driving the glass-lined equipment to rotate, making it conform to the wind direction, and thus reducing the shaking amplitude of the glass-lined equipment; If the wind force at the port is too strong and causes the crane body 1 to shake, the servo motor 33 is started in reverse at this time to reset the diversion shaft 14, and the tensioned connecting steel rope 26 and the side groove 32 are used to limit the diversion shaft 14. Then, all the hydraulic cylinders 27 are contracted to reduce the gap between the socket ring plate 5 and the mounting plate 31. After the contraction is completed, it is ensured that the hydraulic cylinders 27 are completely locked under the action of the mechanical locking pins 28. Then, multiple counterweight boxes 20 can be used, in cooperation with the connecting blocks 22 and bolts 21 arranged on the outside thereof, to splice the hook assemblies 4 of the two cranes, increase the connection between the two crane bodies 1, and thus jointly resist the hurricane.
