Description

Technical Field

[0001] This patent relates to the technical field of boiler transportation, and specifically relates to a vertical boiler transportation platform. Background Technique

[0002] Vertical boilers are widely used thermal energy equipment with many advantages: small floor area after installation, compact structure, etc. Due to the height limit of domestic road transportation, the height of large-tonnage vertical boiler bodies cannot meet the road transportation limit, and they can only be laid down horizontally for fixed transportation. The internal structure of vertical boilers is complex. If only using the lifting lugs at the upper and lower ends of the boiler, the boiler legs and the boiler transportation platform for fixation, it is easy to make the internal components such as the furnace lining and pipelines subject to uneven pressure, resulting in deformation, damage or rupture. For this reason, we propose a vertical boiler transportation platform. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of this patent in conjunction with the accompanying drawings in the embodiments of this patent. Obviously, the described embodiments are only a part of the embodiments of this patent, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this patent without creative efforts shall fall within the scope of protection of this patent.

[0019] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 This patent provides a technical solution: a vertical boiler transportation rack, including side beams 1, the number of side beams 1 is two, a cross beam 2 is fixedly installed between the two side beams 1, gantry frames 3 are fixedly installed at the tops of the two side beams 1, lifting lug fixing plates 4 are fixedly installed at the front and rear ends on the right side of the left gantry frame 3, mounting holes are provided on the lifting lug fixing plates 4, a leg fixing plate 5 is fixedly installed on the left side of the right gantry frame 3, and mounting holes are provided on the leg fixing plate 5;

[0020] The position of the lifting lug fixing plate 4 fits with the position of the boiler product lifting lug and is fixed by bolts.

[0021] The leg fixing plate 5 can be an iron plate, and the mounting holes on the iron plate are fixed to the bolt holes of the boiler leg bottom plate by bolts.

[0022] The cross beam 2 includes a first column body 6 and a second column body 9. A chute 7 is provided at the right end of the first column body 6, a strip hole 8 is provided at the bottom of the side wall of the chute 7, the side wall of the second column body 9 is relatively fitted and slid with the inner side wall of the chute 7, a screw rod 10 is integrally formed at the top of the side wall of the second column body 9, and the top end of the screw rod 10 passes through the strip hole 8 and is screwed with a nut 11.

[0023] By dividing the cross beam 2 into the first column body 6 and the second column body 9, the length can be adjusted according to different types of boilers.

[0024] Specifically, a collar 20 is fixedly installed on the first column body 6. The collar 20 includes a ring body, a cross plate is fixedly installed on the inner side wall of the ring body, and mounting holes are provided on the cross plate.

[0025] Long bolts are provided in the mounting holes of the cross plate.

[0026] During installation, the position of the manhole of the boiler (the cover of the manhole needs to be removed) is downward, so that the bottom of the manhole ring of the boiler fits on the top of the ring body (the diameters of the manhole ring and the ring body are the same). Then, the hand of the installer reaches into the ring body from the bottom of the cross beam 2 to turn the long bolt, so that the end of the bolt presses against the inner side wall of the manhole ring of the boiler.

[0027] Specifically, the nut 11 includes an internal thread ring 12 and a pressing ring 13. The internal thread ring 12 is screwed onto the screw rod 10. On both the front and rear sides of the bottom of the pressing ring 13, insertion teeth 14 are integrally formed. On both the front and rear sides of the top of the side wall of the first cylinder 6, tooth grooves are provided which are continuously distributed left and right. The bottom of the internal thread ring 12 is closely attached to the top of the pressing ring 13, the bottom of the pressing ring 13 is closely attached to the top of the side wall of the first cylinder 6, and the insertion teeth 14 are inserted into the tooth grooves.

[0028] The two rows of tooth grooves are respectively located on the front and rear sides of the strip-shaped hole 8.

[0029] By providing the insertion teeth 14, the locking effect of the nut 11 on the outer side wall of the first cylinder 6 can be further increased.

[0030] Specifically, on both the left and right ends of the side wall of the screw rod 10, limiting slideways 16 are provided. On both the left and right ends of the inner side wall of the pressing ring 13, sliding blocks 15 are integrally formed. The two sliding blocks 15 are respectively slidably installed in the two limiting slideways 16.

[0031] By providing the sliding blocks 15 to be slidably installed in the limiting slideways 16, the movement trajectories of the pressing ring 13 and the insertion teeth 14 are limited, so that the pressing ring 13 and the insertion teeth 14 can only move up and down relative to the screw rod 10.

[0032] Specifically, an annular groove 17 is provided on the outer side wall of the pressing ring 13. A rotating ring 18 is rotatably installed in the annular groove 17. The shape and size of the rotating ring 18 match the internal shape and size of the annular groove 17. A connecting ring 19 is fixedly installed on the outer side wall of the rotating ring 18. The upper side of the inner side wall of the connecting ring 19 is fixedly installed on the outer side wall of the internal thread ring 12.

[0033] The rotating ring 18 can only rotate in the annular groove 17 and cannot move in other directions in the annular groove 17, which is used to make the internal thread ring 12 and the pressing ring 13 rotate relative to each other.

[0034] When the internal thread ring 12 is rotated to move it up and down, the pressing ring 13 can be driven to move up and down simultaneously through the rotating ring 18.

[0035] Specifically, the rotating ring 18 includes a first half ring and a second half ring. The two ends of the first half ring and the second half ring are opposite to each other. The outer side walls of the first half ring and the second half ring are fixed to the inner side wall of the connecting ring 19.

[0036] By dividing the rotating ring 18 into the first half ring and the second half ring, it is convenient to install the rotating ring 18 in the annular groove 17 in the early stage. After the installation is completed, the outer side walls of the first half ring and the second half ring are fixed to the inner side wall of the connecting ring 19.

[0037] Working principle: During installation, place the boiler horizontally on the crossbeam 2. The position of the lifting lug fixing plate 4 coincides with the position of the lifting lugs of the boiler product and is fixed by bolts. The leg fixing plate 5 can be an iron plate, and the mounting holes on the iron plate are fixed to the bolt holes of the boiler leg bottom plate by bolts. The manhole of the boiler (the cover of the manhole needs to be removed) faces downward, so that the bottom of the manhole ring of the boiler fits against the top of the ring body (the diameters of the manhole ring and the ring body are the same). Then, the installer reaches into the ring body from the bottom of the crossbeam 2 with his hand to turn the longer bolt, so that the end of the bolt presses against the inner side wall of the manhole ring of the boiler.
