Description

Technical Field

[0001] This invention relates to the field of mechanical manufacturing technology, specifically to an installation device for extra-long internal components of large horizontal equipment. Background Technology

[0002] As chemical processes become increasingly complex, users have a stronger demand for economical and efficient equipment structures. In actual use, large horizontal equipment requires the installation of numerous internal components or modules to achieve various mass and heat transfers, chemical reactions, and functional integration while saving space. For example, when assembling and using horizontal pressure vessels, it may be necessary to install extra-long internal components such as catalysts, packing materials, or heat exchanger tube bundles according to actual usage requirements. Due to increasing usage and functional demands, the size of horizontal equipment is growing, and the length and weight of internal components are gradually increasing. The installation of extra-long internal components in large horizontal equipment is becoming increasingly complex, and conventional lifting devices can no longer meet the installation requirements. During the installation of long internal components, insufficient support can easily lead to them falling or loosening, which will reduce the installation quality of extra-long internal components in large horizontal equipment and pose safety hazards. Summary of the Invention

[0003] The purpose of this invention is to provide an installation device for extra-long internal components of large horizontal equipment, in order to solve the problem mentioned in the background art that the installation of extra-long internal components of large horizontal equipment is becoming increasingly complex, and conventional lifting devices can no longer meet the installation requirements. When installing long internal components, insufficient support during installation can easily lead to them falling or loosening, which will reduce the installation quality of extra-long internal components of large horizontal equipment and pose safety hazards.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an installation device for extra-long internal components of a large horizontal equipment, comprising an inlet assembly and a lifting assembly. The lifting assembly includes a lifting guide beam, and the inlet assembly includes an inlet guide beam installed in the large horizontal equipment. The lifting guide beam is fastened to the inlet guide beam, and one end of the inlet guide beam extending into the interior of the large horizontal equipment abuts against the inner wall of the large horizontal equipment. Multiple sets of pulley assemblies for connecting with the extra-long internal components are slidably arranged inside the lifting guide beam. Both the lifting guide beam and the inlet guide beam are in the shape of an "I" shape. Two slide rail grooves are formed in the middle of the "I" shape, allowing the pulley assemblies to drive the extra-long internal components to slide. Each pulley assembly includes a lifting rope fixedly connected to its bottom, which is used to connect to the bottom and sides of the extra-long internal components. The lifting assembly also includes an adjusting component disposed inside the large horizontal equipment. The adjusting component is connected to the inlet guide beam, and the adjusting component can adjust the tilt angle of the inlet guide beam so that the pulley assembly carries the extra-long internal components and slides into the large horizontal equipment on its own.

[0005] Preferably, the adjusting component includes multiple sliding plates, multiple stretching round steel bars, and multiple limiting round steel bars. The sliding plates are slidably connected to the top of the guide rail beam. The sliding plates have an interface that matches the top of the guide rail beam. The interface is slidably connected to the guide rail beam. The stretching round steel bars are connected to the top of the sliding plates. The stretching round steel bars have multiple positioning holes. The limiting round steel bars are inserted into the positioning holes.

[0006] Preferably, the lifting assembly further includes a lifting beam, a lifting hole, an upper connecting plate, a lower connecting plate, multiple upper connecting bolts, and multiple lower connecting bolts. The lifting beam is fixedly connected to the top of the lifting guide beam. The lifting hole is opened through the top of the lifting beam. The top of the connection between the lifting guide beam and the guide beam is fastened with an upper connecting plate. The upper connecting plate is internally threaded with an upper connecting bolt. Both the lifting guide beam and the guide beam have threaded through holes adapted to the upper connecting plate. The bottom of the connection between the lifting guide beam and the guide beam is fastened with a lower connecting plate. The lower connecting plate is internally threaded with a lower connecting bolt. Both the lifting guide beam and the guide beam have threaded through holes adapted to the lower connecting bolts. Nuts are threaded into both the upper and lower connecting bolts.

[0007] Preferably, the pulley assembly includes a round steel bending rod, two sliding sleeves, and multiple limiting bushings. The two sliding sleeves are rotatably connected to both ends of the round steel bending rod, and the sliding sleeves are slidably connected to the slide rail groove. The limiting bushings are fixedly connected to both ends of the round steel bending rod, and the sliding sleeves are disposed between the two limiting bushings.

[0008] Preferably, the end of the lifting guide beam away from the guide beam is threaded with two external limiting bolts, which are positioned on the moving path of the pulley assembly to restrict its movement. The end of the guide beam away from the lifting guide beam is threaded with two internal limiting screws, which are positioned on the moving path of the pulley assembly to restrict its movement.

[0009] Preferably, two adjacent lower connecting bolts are equidistant from each other, the lower connecting bolts are positioned inside the slide rail groove, and the lower connecting bolts are positioned outside the movement path of the pulley assembly.

[0010] The installation method for the extra-long internal component mounting device of large horizontal equipment includes the following steps:

[0011] S1. First, pass the extra-long equipment through the connection between the hoisting rope and the pulley assembly, use the hoisting rope to hold the extra-long internal parts, and then connect multiple sets of pulley assemblies with the lifting guide beam and slide them into the slide rail groove.

[0012] S2. Pass multiple stretched round steel bars through the reserved pipes of the large horizontal equipment, and adjust the horizontal angle of the guide rail beam according to the actual installation requirements. Specifically, gradually increase the insertion depth of the multiple stretched round steel bars from the reserved pipes near the outside of the large horizontal equipment, so that the guide rail beam tilts towards the inside of the large horizontal equipment. Then, insert multiple limiting round steel bars into the corresponding stretch round steel bars. Use the limiting round steel bars to abut against the top of the reserved pipe to support the stretch round steel bars and the sliding plate. Then, connect the guide rail beam with the sliding plate and slide it into the inside of the large horizontal equipment to complete the installation of the guide component.

[0013] S3. When installing the lifting assembly, use existing crane equipment to connect through the lifting hole to lift the lifting guide beam as a whole and suspend it in the air. Then, connect the lifting guide beam with the guide beam. At the same time, apply traction force to the extra-long internal component to position it. Fit the upper connecting plate and the lower connecting plate with the top and bottom of the connection between the lifting guide beam and the guide beam, respectively. Screw the upper connecting bolt and the lower connecting bolt into the corresponding positions. Finally, screw multiple nuts into the upper connecting bolt and the lower connecting bolt and tighten them to fix it. The connection of the lifting assembly is completed, and the lifting guide beam and the guide beam are in a parallel state.

[0014] S4. Then, remove the force applied to the extra-long internal component. The extra-long internal component will slide into the large horizontal equipment by its own weight with the help of the sliding sleeve within the lifting guide beam and the guide beam. After that, the regular installation operation can be carried out. After the installation of the extra-long internal component is completed, the upper and lower connecting bolts can be removed by unscrewing the nuts, and the lifting assembly can be taken off.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention improves the installation efficiency of extra-long internal components by gradually increasing the insertion depth of multiple stretched round steel bars through a pre-reserved pipe near the exterior of a large horizontal equipment. This causes the guide rail beam to tilt towards the interior of the large horizontal equipment, and an external lifting guide rail beam forms a sloped track. The weight of the extra-long internal components drives the pulley assembly to move into the large horizontal equipment to a designated position, thus improving the installation efficiency of extra-long internal components.

[0017] This invention involves placing an inlet component inside a large horizontal equipment and connecting a lifting component to the outside of the equipment. A pulley assembly is connected to an extra-long internal component, which is then slid into the inlet component. This inlet component provides support for the extra-long internal component, increasing its support strength and preventing loosening due to insufficient support during installation. Furthermore, the simple structural connections facilitate the removal of the lifting component after installation, simplifying operation and improving installation safety. This invention also boasts strong versatility. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-5 One embodiment provided by the present invention:

[0026] A device for installing extra-long internal components of a large horizontal equipment includes an inlet assembly and a lifting assembly. The lifting assembly includes a lifting guide beam 1, and the inlet assembly includes an inlet guide beam 10 installed on the large horizontal equipment. The lifting guide beam 1 and the inlet guide beam 10 are fastened together. One end of the inlet guide beam 10 extends into the interior of the large horizontal equipment and abuts against the inner wall of the equipment. Multiple sets of pulley assemblies 3 for connecting to the extra-long internal components are slidably installed inside the lifting guide beam 1. Both the lifting guide beam 1 and the inlet guide beam 10 are I-shaped, with two slide rail grooves formed in the middle of the I-shape for the pulley assemblies 3 to drive the extra-long internal components to slide. The pulley assembly 3 includes a lifting rope 4 fixedly connected to its bottom, which is used to connect to the bottom and sides of the extra-long internal components. The lifting assembly also includes an adjustment mechanism installed inside the large horizontal equipment. The section and adjustment component are connected to the guide rail beam 10, and the adjustment component can adjust the tilt angle of the guide rail beam 10 so that the pulley assembly 3 can slide into the large horizontal equipment with the extra-long inner part. The guide assembly is set inside the large horizontal equipment and connected to the lifting assembly outside the large horizontal equipment. The pulley assembly 3 is connected to the extra-long inner part and the extra-long inner part is slid into the guide assembly of the large horizontal equipment. Thus, the guide assembly provides support for the extra-long inner part, which improves the support strength for the extra-long inner part and avoids the loosening of the connection due to insufficient support strength when installing the extra-long inner part. At the same time, through the simple combination and connection between the structures, it is convenient to remove the lifting assembly after the extra-long inner part is installed. This simplifies the operation of the device and improves the safety of installation. It has the advantage of strong versatility.

[0027] Please see Figure 1 , Figure 4 In this embodiment, the adjusting component includes multiple sliding plates 13, multiple tensile round steel bars 8, and multiple limiting round steel bars 9. The sliding plates 13 are slidably connected to the top of the guide rail beam 10. The sliding plates 13 have an interface that matches the top of the guide rail beam 10. The interface is slidably connected to the guide rail beam 10. The tensile round steel bars 8 are connected to the top of the sliding plates 13. The tensile round steel bars 8 have multiple positioning holes. The limiting round steel bars 9 are inserted into the positioning holes. During installation, the multiple tensile round steel bars 8 are first passed through the reserved pipe of the large horizontal equipment, and the horizontal angle of the guide rail beam 10 is adjusted according to the actual installation requirements. Then, the multiple limiting round steel bars 9 are inserted into the tensile round steel bars 8 at the corresponding positions. The limiting round steel bars 9 and the top of the reserved pipe are used to support the tensile round steel bars 8 and the sliding plates 13. Then, the guide rail beam 10 is connected to the sliding plates 13 and slid into the large horizontal equipment to complete the installation of the guide component.

[0028] It should be noted that the connection between the tension round steel 8 and the sliding plate 13 includes, but is not limited to, two connection methods: welding and rotation. When the required tilt angle of the guide rail beam 10 is small, both welding and rotation can be used. When the required tilt angle of the guide rail beam 10 is large, only rotation can be used to achieve the required tilt angle. In order to maintain the connection stability between the limiting round steel 9 and the reserved pipe, the connection between the limiting round steel 9 and the reserved pipe can be spot welded using commonly used electric welding equipment in the prior art, thereby strengthening the connection between the limiting round steel 9 and the reserved pipe. Furthermore, the part of the tension round steel 8 extending to the outside of the reserved pipe can also be fixed by spot welding, further improving the connection stability with large horizontal equipment.

[0029] Please see Figure 1 , Figure 2 , Figure 4 The lifting assembly also includes a lifting beam 2, a lifting hole 14, an upper connecting plate 5, a lower connecting plate 6, multiple upper connecting bolts 7, and multiple lower connecting bolts 15. The lifting beam 2 is fixedly connected to the top of the lifting guide beam 1. The lifting hole 14 is opened through the top of the lifting beam 2. The top of the connection between the lifting guide beam 1 and the guide beam 10 is fastened with the upper connecting plate 5. The upper connecting plate 5 is internally threaded with the upper connecting bolts 7. Both the lifting guide beam 1 and the guide beam 10 have threaded through holes adapted to the upper connecting plate 5. The bottom of the connection between the lifting guide beam 1 and the guide beam 10 is fastened with the lower connecting plate 6. The lower connecting plate 6 is internally threaded with the lower connecting bolts 15. Both the lifting guide beam 1 and the guide beam 10 have threaded through holes adapted to the lower connecting bolts 15. The upper connecting bolt 7 and the lower connecting bolt 15 are threaded with nuts. First, the extra-long equipment is passed through the connection between the lifting rope 4 and the pulley assembly 3. The extra-long internal parts are supported by the lifting rope 4. When installing the lifting assembly, the existing crane equipment is used to connect through the lifting hole 14 to lift the lifting guide beam 1 as a whole and suspend it in the air. Then, the lifting guide beam 1 is connected to the guide beam 10. The upper connecting plate 5 and the lower connecting plate 6 are respectively attached to the top and bottom of the connection between the lifting guide beam 1 and the guide beam 10. The upper connecting bolt 7 and the lower connecting bolt 15 are screwed into the corresponding positions. Finally, multiple nuts are screwed into the upper connecting bolt 7 and the lower connecting bolt 15 and tightened to fix them. The connection of the lifting assembly is then completed.

[0030] It should be noted that the aforementioned reserved pipelines are actually pre-installed during manufacturing and serve functions such as venting, ventilation, feeding, discharging, cooling, heating, monitoring, measurement, and safety accessories. Pipelines for venting and ventilation are used to discharge gases from the container to maintain stable internal pressure and ensure safe operation. Pipelines for feeding and discharging facilitate the transfer of materials into or out of the container. Pipelines for cooling and heating are used in chemical reactions or storage processes requiring temperature control; these pipes may be used to transport coolants or heating media, which can circulate within the container to maintain the required temperature range. Pipelines for monitoring and measurement are used to install sensors or instruments to monitor parameters such as pressure, temperature, and liquid level within the container. This monitoring data is crucial for ensuring the safe operation and process control of the container. Horizontal pressure vessels are also typically equipped with various safety accessories, such as safety valves and rupture discs. These accessories are usually also connected to the container via piping systems to ensure timely response and measures to protect equipment and personnel in abnormal situations.

[0031] Please see Figure 5 In this embodiment, the pulley assembly 3 includes a round steel bending rod 301, two sliding sleeves 302, and multiple limiting lugs 303. The two sliding sleeves 302 are rotatably connected to both ends of the round steel bending rod 301, and the sliding sleeves 302 are slidably connected to the slide rail groove. The limiting lugs 303 are fixedly connected to both ends of the round steel bending rod 301. The sliding sleeves 302 are arranged between the two limiting lugs 303. The extra-long equipment passes through the connection between the lifting rope 4 and the pulley assembly 3. The lifting rope 4 is used to hold the extra-long internal parts. Then, the multiple sets of pulley assemblies 3 are connected to the lifting guide beam 1 and slid into the slide rail groove, thus completing the connection between the multiple sets of pulley assemblies 3 and the extra-long internal parts.

[0032] The installation method for the extra-long internal component mounting device of large horizontal equipment includes the following steps:

[0033] S1. First, pass the extra-long equipment through the connection between the hoisting rope 4 and the pulley assembly 3, use the hoisting rope 4 to hold the extra-long internal parts, and then connect multiple sets of pulley assemblies 3 with the lifting guide beam 1 and slide them into the slide rail groove.

[0034] S2. Pass multiple stretched round steel bars 8 through the reserved pipes of the large horizontal equipment, and adjust the horizontal angle of the guide rail beam 10 according to the actual installation requirements. Specifically, gradually increase the insertion depth of the multiple stretched round steel bars 8 from the reserved pipes near the outside of the large horizontal equipment, so that the guide rail beam 10 tilts towards the inside of the large horizontal equipment. Then, insert multiple limiting round steel bars 9 into the corresponding positions of the stretched round steel bars 8. Use the limiting round steel bars 9 to abut against the top of the reserved pipe to support the stretched round steel bars 8 and the sliding plate 13. Then, connect the guide rail beam 10 with the sliding plate 13 and slide it into the inside of the large horizontal equipment to complete the installation of the guide component.

[0035] S3. When installing the lifting assembly, use the existing crane equipment to connect through the lifting hole 14 to lift the lifting guide beam 1 as a whole and suspend it in the air. Then, connect the lifting guide beam 1 with the guide beam 10. At the same time, apply traction force to the extra-long internal parts to position them. Fit the upper connecting plate 5 and the lower connecting plate 6 with the top and bottom of the connection between the lifting guide beam 1 and the guide beam 10, respectively. Screw the upper connecting bolt 7 and the lower connecting bolt 15 into the corresponding positions. Finally, screw multiple nuts into the upper connecting bolt 7 and the lower connecting bolt 15 and tighten them to fix them. The connection of the lifting assembly can be completed, and the lifting guide beam 1 and the guide beam 10 are in a parallel state.

[0036] S4. Then, the force applied to the extra-long internal component is removed. The extra-long internal component slides into the large horizontal equipment by its own weight with the help of the sliding sleeve 302 within the lifting guide beam 1 and the guide beam 10. After that, the regular installation operation can be carried out. After the installation of the extra-long internal component is completed, the upper connecting bolt 7 and the lower connecting bolt 15 can be removed by unscrewing the nut, and the lifting assembly can be removed.

[0037] It should be noted that the limiting lug 303 is specifically formed by spot welding the round steel bending rod 301 on both sides of the sliding sleeve 302 using electric welding equipment in the conventional operation of the prior art. It is used to restrict the degree of freedom of the sliding sleeve 302 and facilitate its use.

[0038] Please see Figure 1 , Figure 4In this embodiment, the end of the lifting guide beam 1 away from the guide beam 10 is threaded with two external limiting bolts 12. The external limiting bolts 12 are positioned on the moving path of the pulley assembly 3 to restrict its movement. The end of the guide beam 10 away from the lifting guide beam 1 is threaded with two internal limiting screws 11. The internal limiting screws 11 are positioned on the moving path of the pulley assembly 3 to restrict its movement. This arrangement can limit the range of movement of the pulley assembly 3 and prevent excessive movement of the pulley assembly 3 from affecting subsequent installation. The two adjacent lower connecting bolts 15 are equidistant from each other. The lower connecting bolts 15 are positioned inside the slide rail groove and outside the moving path of the pulley assembly 3 to prevent the lower connecting bolts 15 from appearing in the moving path of the pulley assembly 3 and affecting its movement.

[0039] Working principle: During installation, firstly, the extra-long equipment is passed through the connection between the lifting rope 4 and the pulley assembly 3. The lifting rope 4 is used to hold the extra-long internal components. Then, multiple sets of pulley assemblies 3 are connected to the lifting guide beam 1 and slid into the slide rail groove. Secondly, multiple tensile round steel bars 8 are passed through the reserved pipe of the large horizontal equipment, and the horizontal angle of the guide beam 10 is adjusted according to the actual installation requirements. Then, multiple limiting round steel bars 9 are inserted into the corresponding positions of the tensile round steel bars 8. The limiting round steel bars 9 abut against the top of the reserved pipe to support the tensile round steel bars 8 and the sliding cover plate 13. Finally, the guide beam 10 is connected to the sliding cover plate 13 and slid into the large horizontal equipment, thus completing the installation of the guide assembly. When installing the lifting assembly, a crane is used in the prior art to connect through the lifting hole 14. The lifting guide beam 1 is lifted and suspended in the air. Then, the lifting guide beam 1 is connected to the guide beam 10. The upper connecting plate 5 and the lower connecting plate 6 are respectively attached to the top and bottom of the connection between the lifting guide beam 1 and the guide beam 10. The upper connecting bolt 7 and the lower connecting bolt 15 are screwed into the corresponding positions. Finally, multiple nuts are screwed into the upper connecting bolt 7 and the lower connecting bolt 15 and tightened to fix them. The connection of the lifting assembly is then completed. Finally, the extra-long internal component is pushed into the large horizontal equipment by sliding the sliding sleeve 302 within the lifting guide beam 1 and the guide beam 10. Then, the routine installation operation can be carried out. After the installation of the extra-long internal component is completed, the upper connecting bolt 7 and the lower connecting bolt 15 are removed by unscrewing the nuts, and the lifting assembly can be removed.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
