[0002] In chemical production, towers are indispensable equipment in chemical equipment. The vertical height is usually tens of meters or even hundreds of meters. Usually, maintenance platforms are set up at the manhole and discharge port of the tower body to facilitate the replacement and maintenance of internal parts and fillers during the use of the equipment. As a simple lifting tool, the tower top sling can lift and transport some equipment parts or fillers in the tower from the ground to the platform at the manhole. The commonly used lifting weight of the sling is 500kg and 1000kg, which can effectively reduce the use of large lifting equipment and reduce production costs. At present, the commonly used sling temperature is above -30℃. When the operating temperature is lower than -30℃, it should be stopped.

[0003] With the development of process technology, the working temperature of many tower equipment reaches -70℃, and the design temperature reaches -80℃. Therefore, when the equipment is running, the working environment temperature of the tower top davit is lower than -30℃, which makes the performance of the existing tower top davit unguaranteed, and it is easy to cause hoisting safety accidents. The existing davits can no longer meet the production activity requirements of this part of tower equipment, and only large hoisting machinery can be used to complete the hoisting operation, which increases the production cost.

[0053] An upper pad 2 is sandwiched between the guide connecting plate 25 and the upper connecting plate 13. The upper pad 2 and the upper connecting plate 13 are provided with connecting holes at positions corresponding to the connecting holes of the guide connecting plate 25 and are fixed by bolts.

[0054] like Figure 10-12 As shown, the lower side of the limiting seat 7 is connected to the lower support 6, and the lower support 6 includes a lower connecting plate a20, a lower rib plate a21 and a lower connecting plate b22. The lower rib plate a21 lacks a plate corner, and a complete plate edge of the lower rib plate a21 is fixed to the lower plate surface of the lower connecting plate a20, and another complete plate edge of the lower rib plate a21 is fixed to the plate surface of the lower connecting plate b22.

[0056] A lower pad 5 is sandwiched between the lower connecting plate c17 and the lower connecting plate b22. Fig. 9 As shown, a through groove is provided at the lower part of the lower pad 5, and the support plate 18 of the lower bracket 4 can be just inserted into the through groove of the lower pad 5, and the lower connecting plate c17, the lower connecting plate b22 and the lower pad 5 are fixed with bolts passing through them.

[0057] In this embodiment, the limit seat 7 includes a steel pipe 23 and a connecting plate d24, the steel pipe 23 is welded to a plate surface of the connecting plate d24, the upper bracket 1 and the lower bracket 4 are made of the same material as the equipment shell, and the upper and lower pads 5 are respectively arranged between the upper bracket 1 and the guide frame 8, and between the lower bracket 4 and the lower support 6, which can effectively block the cold transfer of the shell to the suspension rod 10 and the bracket, and ensure that the performance of the suspension rod 10 and the bracket is not reduced due to the low temperature working conditions of the equipment. The upper pad 2 and the lower pad 14 are both made of pine wood soaked in asphalt, which can effectively prevent the cold transfer and avoid the formation of cold bridges, and play the role of cold insulation, vibration reduction and thermal expansion buffering.

[0058] The outer circumference of the sleeve 26 on the guide plate 27 is uniformly distributed with guide holes 271, and a movable latch device is fixed on the vertical straight section of the suspension rod 10. The movable latch device is inserted into or pulled out of the guide hole 271 to achieve the fixation and rotation of the suspension rod 10. The movable latch device includes a stop latch 9, an upper ear plate 30 and a lower ear plate 31; the stop latch 9 is provided with a stopper a281 and a stopper b282 with staggered vertical and horizontal positions, and the size of the stopper b282 is not larger than that of the stopper a281. The stop latch 9 includes a horizontal section and a vertical section. The upper ear plate 30 and the lower ear plate 31 are fixed on the vertical straight section of the suspension rod 10. The upper ear plate 30 is provided with a through hole only for the vertical section of the stop latch 9 and the stopper a281 to pass through, and the lower ear plate 31 is provided with a through hole only for the vertical section of the stop latch 9 to pass through.

[0059] The outer periphery of the limit seat 7 is provided with a rain cover 3 that can pass through the vertical straight section of the suspension rod 10, and the free end of the horizontal straight section of the suspension rod 10 is provided with a baffle 35, and the inner side of the baffle 35 is provided with a hook 34, which is mainly used to hang the pulley assembly, and the hook 34 can be a U-shaped hook. A stopper c36 is provided on the lower side of the guide frame 8 installed on the vertical straight section of the suspension rod 10 to prevent the guide frame 8 from accidentally falling.

[0060] When manufacturing the equipment, the upper bracket 1 and the lower bracket 4 are welded to the equipment shell respectively, the guide frame 8 is connected to the upper bracket 1 by the upper pad 2 through the connecting bolts, and the lower support 6 is connected to the lower bracket 4 by the lower pad 5 through the connecting bolts. Then install the suspension rod 10, the vertical straight section of the suspension rod 10 passes through the sleeve 26 on the guide plate 27, passes through the rain cover 3, and the bottom end of the vertical straight section of the suspension rod 10 is inserted into the steel pipe 23 on the limit seat 7, the lower block c36 of the guide frame 8 is welded, and finally the stop pin device is installed to complete the assembly of the suspension column. Before welding the upper and lower ear plates, the stopper b282 on the vertical section of the stop pin 9 should be passed through the upper ear plate in advance. The reason is that after the upper ear plate 30 is installed in the equipment housing, the horizontal section of the stop pin 9 can only rotate to make the stopper a281 pass through the upper ear plate 30. Due to the obstruction of the equipment housing, the horizontal section of the brake pin 9 cannot be rotated to the angle where the stopper b282 also passes through the upper ear plate 30. That is, the stop pin 9 needs to be assembled with the upper ear plate 30 in advance. This design can prevent the stop pin 9 from being lost after the operator removes it when rotating the hanging column.

[0061] When in use, lift the stop pin 9, rotate the boom 10 to a suitable position by rotating the handle 29, and then lower the stop pin 9 to fix the boom 10. Hang the pulley assembly on the hook 34 of the horizontal straight section of the boom 10 to lift the material up and down.

[0062] When the suspension column is not in use, the vertical section of the stop pin 9 passes through the lower ear plate 31 welded on the suspension rod 10 and is inserted into the guide hole 271 of the guide plate 27, thereby fixing the suspension rod 10 and preventing it from rotating. When the suspension column is in use, the stop pin 9 is lifted so that the stop pin 9 block a281 is located on the upper side of the upper ear plate 30, and the stop pin 9 is rotated so that the stop pin 9 block a281 is suspended on the upper side of the upper ear plate 30. At this time, the suspension rod 10 can be rotated, and the rotating handle 29 is rotated to rotate the suspension rod 10 to the required position, and the stop pin 9 is rotated again so that the stop pin 9 falls into the guide hole 271 of the guide plate 27, thereby fixing the suspension rod 10 to the required position for lifting operations.

[0063] The above is only a specific implementation of the utility model, which enables those skilled in the art to understand or implement the utility model. Although detailed descriptions are given with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments, and they should all be covered by the protection scope of the claims.
