Description

Technical Field

[0001] The utility model relates to the field of support devices for chemical equipment maintenance, in particular to a support device for chemical equipment maintenance. Background Technique

[0002] Chemical equipment is a part of chemical machinery. Chemical machinery includes two parts. One is chemical machinery, mainly referring to equipment such as fans, compressors, and various pumps for fluid transportation. Its main components are moving machinery, generally called chemical machinery. The other is chemical equipment, mainly referring to machinery with stationary components, such as separation equipment like tower vessels, container and reactor equipment, etc., sometimes also called non-standard equipment.

[0003] In the chemical industry, for tower tank equipment such as spherical tanks, some are pressure vessels and need to be inspected and repaired regularly. For spherical tanks, manholes are located at the bottom and top, facilitating convective replacement and personnel entry and exit. In most cases, pipelines are connected below the bottom manhole and need to be removed during maintenance. For example, there are a total of 5 valves at the connection short section of the lower manhole of a liquid ammonia spherical tank, and the pipeline length is 2.5 meters. Due to the spherical structure of the spherical tank, there are no available anchoring points on site for hoisting. If all the valves are disassembled in sections, not only will the workload increase significantly, but excessive flange disassembly will easily increase the leakage risk. Moreover, the leakage of liquid ammonia is extremely harmful. Especially if the root valve leaks, the consequences are unacceptable.

[0004] Therefore, it is necessary to provide a support device for chemical equipment maintenance to solve the above technical problems. It can adjust the support spacing according to the length of the pipeline to be disassembled and freely adjust the support height, reduce the number of flange disassembly, reduce the leakage risk, and at the same time have the function of supporting, disassembling, and removing the pipeline below the equipment, facilitating maintenance personnel to enter and exit through the lower manhole of the tower tank equipment to meet the needs of daily operations. Disclosing the information of this background technical part is only intended to increase the understanding of the overall background of the present invention, and is not necessarily regarded as an admission or an indication in any form that this information constitutes the prior art already known to those of ordinary skill in the art.

[0011] Compared with the related technology, a support device for chemical equipment maintenance provided by the utility model has the following beneficial effects:

[0012] The utility model provides a support device for chemical equipment maintenance. First, the fixed beam and the base are moved to the lower part of the external tower tank equipment through the universal wheels. The support spacing is adjusted according to the length of the pipeline to be disassembled under the tower tank equipment. At this time, the stepping motor drives the lead screw to rotate through the bearing seat. The rotation of the lead screw drives the nut seat to move outwards.

[0023] Embodiment 1:

[0024] Please refer to Figures 1-3 , the present invention provides a technical solution: a support device for chemical equipment maintenance, including a base 1. A partition 2 is vertically fixedly connected to the center of the inner cavity of the base 1. Stepping motors 3 are fixedly connected to both sides of the partition 2. A lead screw 4 is fixedly connected to the output end of the stepping motor 3. A nut seat 5 is threadedly connected to the inner side of the surface of the lead screw 4. A support block 6 is fixedly connected to the top of the nut seat 5. The top of the support block 6 penetrates through the top of the base 1 and is fixedly connected to a support plate 7. A housing 8 is fixedly connected to the top of the support plate 7. An electric hydraulic rod 9 is fixedly connected to the bottom of the inner cavity of the housing 8. A top plate 10 is fixedly connected to the top of the electric hydraulic rod 9. A top column 11 is fixedly connected to the top of the top plate 10. The top of the top column 11 penetrates through the top of the housing 8 and is fixedly connected to an arc-shaped clamping block 12. Sliding sleeves 13 are fixedly connected to the front and back of the top plate 10. A sliding rod 14 is slidably connected to the inner cavity of the sliding sleeve 13. The top and bottom of the sliding rod 14 are fixedly connected to the top and bottom of the inner cavity of the housing 8.

[0025] In this implementation scheme, through the anti-collision pad, it plays a role in preventing bumps during the use of the arc-shaped clamping block 12. Through the limit chute 15 and the limit slider 16, it plays a role in limiting the movement of the nut seat 5 during use. At the same time, the arc-shaped clamping block 12 is a modular structure (including a fixing function) and is suitable for different pipe diameters.

[0026] Embodiment 2:

[0027] Please refer to Figures 1-3As shown, on the basis of the first embodiment, the present utility model provides a technical solution: an anti-collision pad is arranged in the inner cavity of the arc-shaped clamping block 12, and the material of the anti-collision pad is rubber. Limiting sliding grooves 15 are opened on both sides of the bottom of the inner cavity of the base 1. A limiting slider 16 is slidably connected in the inner cavity of the limiting sliding groove 15.

[0028] In this embodiment: through the fixed beam 17 and the universal wheels 18, it plays a role in facilitating the movement and locking fixation of the base 1 during use. Through the bearing seat, it plays a role in preventing the lead screw 4 from shaking during use.

[0029] The two embodiments described in the present utility model are particularly applicable to supporting pipelines. Especially when it is necessary to repair a liquid ammonia spherical tank, the height of the top column 11 can be adjusted through the electric hydraulic rod 9, and the distance between the two arc-shaped clamping blocks 12 can be adjusted through the stepping motor 3 to achieve stable support for the pipeline at the lower part of the liquid ammonia spherical tank; when forming stable support for the pipeline at the lower part of the liquid ammonia spherical tank, only the flanges at both ends of the pipeline need to be disassembled, and the disassembly and removal of the entire pipeline can be realized; the above working process can avoid the disassembly of the flange in the middle of the pipeline, which not only reduces the labor intensity but also reduces the leakage risk of liquid ammonia after subsequent installation.

[0030] The working principle of a support device for chemical equipment maintenance provided by the present utility model is as follows:

[0031] Implementation steps of the first innovation point:

[0032] The first step: First, move the fixed beam 17 and the base 1 to the lower part of the external tower tank equipment through the universal wheels 18, and adjust the support spacing according to the length of the pipeline to be disassembled under the tower tank equipment. At this time, the stepping motor 3 drives the lead screw 4 to start rotating through the bearing seat;

[0033] The second step: The rotation of the lead screw 4 drives the nut seat 5 to move outwards. The nut seat 5 drives the limiting slider 16 to slide in the limiting sliding groove 15. The nut seat 5 drives the support plate 7 to move outwards through the support block 6. The support plate 7 drives the arc-shaped clamping block 12 to move to the designated position through the outer shell 8 and the top column 11.

[0034] Implementation steps of the second innovation point:

[0035] The first step: When it is necessary to lift and disassemble the pipeline, confirm that the arc-shaped clamping block 12 is under the pipeline, and synchronously drive the top plate 10 to move upwards through the electric hydraulic rod 9. The top plate 10 drives the sliding sleeve 13 to slide on the sliding rod 14. The top plate 10 drives the arc-shaped clamping block 12 to move upwards through the top column 11;

[0036] Step 2: Use the arc-shaped clamping block 12 to lift the pipeline, and then disassemble the pipeline from the peripheral tower tank equipment. After completion, control the height of the arc-shaped clamping block 12 through the electric hydraulic rod 9 and move the pipeline out from under the tower tank equipment.
